Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following further describes the technical solution of the present invention with reference to the drawings and the embodiments.

Referring to fig. 1-13, a fiber winding forming system includes a paying-off mechanism (shown in fig. i) and a winding mechanism (shown in fig. ii) for paying off a strand of fiber from the paying-off mechanism and winding the strand of fiber according to a preset winding line, and a plurality of fiber yarns are gathered into a strand through the paying-off mechanism or a cloth tape is transmitted to the winding mechanism to wind and form a mandrel 100. The molding system has a numerical control system (preferably a Siemens 840D-SL numerical control system) and a hydraulic system to achieve automated operation.

Paying out machine constructs including first guide rail base 1, first guide rail base 1 slides along its length direction and the interval is provided with two at least pay-off (as shown in fig. 2 department III), and through dabber 100's winding demand, adopt two or more pay-off to twine the dabber with stranded cellosilk simultaneously and satisfy the winding requirement. Different winding modes and routes of the fiber filaments on the mandrel 100 are completed by sliding each pay-off device on the first guide rail base 1 according to a set program.

The pay-off device comprises a fiber sand rack 2 and a winding system, wherein the winding system is a wet winding impregnation system or a cloth tape winding system. The fiber sand frame 2 prevents the fiber yarn from being wound into a plurality of rolls, and the fiber yarn is stranded by a wet winding impregnation system matched with the fiber sand frame to be impregnated and then is coiled on the mandrel 100. In order to adapt to the winding of different materials of the mandrel 100, the fiber yarns in the fiber sand frame 2 can be replaced by cloth tapes, and then the cloth tapes are processed by a cloth tape winding system matched with the cloth tapes and then wound on the mandrel 100.

The wet winding impregnation system comprises an impregnation device 3 and a wire nozzle device 4 which are sequentially arranged on the first guide rail base 1 towards the direction of the winding mechanism and have constant impregnation amount. The gum dipping device 3 is provided with a gum tank 31 with constant loading temperature, the heating temperature and the temperature control precision of the gum dipping device are adjustable and controllable within the range of RT-80 ℃, the water bath is matched with a circulating water tank within the fluctuation range of +/-3 ℃, the water supply pipeline has good tightness and is not leaked. The stranded filaments are dipped in glue through a glue tank 31. The glue dipping device 3 has the function of keeping the glue dipping amount constant, and the concrete structure of the glue dipping device comprises a glue squeezing roller device (shown as V in figure 3) arranged at the edge of a glue groove 31 at one side of a fiber strand which is dipped with glue, the glue squeezing roller device is provided with a movable roller 32 and a fixed roller 33 which are arranged in an up-and-down symmetrical mode, the fixed roller 33 is fixed on a supporting plate 34, the movable roller 32 is arranged on the supporting plate 34 in an up-and-down sliding mode, the top of the supporting plate 34 is provided with a screw rod 35, an adjusting nut 36, an adjusting spring 37 and a slide block 38 are sequentially arranged on the screw rod 35, and the bottom of the slide. When the glue is extruded, the adjusting spring 37 and the sliding block 38 are extruded through rotation of the adjusting screw cap 36, the sliding block 38 pushes the rotating shaft of the movable roller 32 to move towards the fixed roller 33, so that the fiber strand is reduced through a gap between the fiber strand and the fixed roller, the glue on the fiber strand is extruded, the glue amount reaches the rated dose, and the uniformity of the glue dipping amount on the fiber strand is improved. After the impregnation, the fiber strand is guided by the nozzle device 4 and is fed to the mandrel 100 to be wound by the winding mechanism.

In order to avoid the problem that the winding quality is reduced due to the fact that the tension force of the fiber strands wound on the mandrel 100 is not uniform, a gravity tensioning device 5 for winding of the winding mechanism is further arranged between the fiber sand rack 2 and the glue dipping device 3, and the device enables the fiber strands to be in a tensioned state constantly under the action of gravity, so that the winding quality of the fiber strands wound on the mandrel 100 is improved.

Specifically, the gravity tensioning device 5 includes a triangular bracket 51 and rollers 52 fixedly disposed on two sides of the triangular bracket 51, an elastic weight 53 is disposed at the bottom of the inner side of the triangular bracket 51, a movable roller 54 for tensioning the fiber is disposed at the top of the triangular bracket, and an adjusting electric cylinder 55 opposite to the elastic weight 53 (the elastic action of which is to dispose a spring 56 at the bottom of the elastic weight) is connected between the top of the movable roller 54 and the top of the triangular bracket 51. The tensioning effect is as follows: the fiber strand is passed through the bottom of the roller 52 and the top of the movable roller 54, and is elastically jacked up and tensioned by the spring at the bottom of the elastic weight 53, and the jacking force of the spring is adjusted to be balanced by the air cylinder.

Because the strap has certain width, need not become the strand like the cellosilk, consequently its skew will influence the winding quality taking place when twining, consequently, strap winding system includes the deviation guide mechanism (as shown in VI in fig. 12), heating running roller 12 and the silk mouth device 4 that set gradually towards the mechanism direction of winding. Wherein the guiding mechanism of rectifying is used for correcting the skew of strap, and concrete structure is including the correction board 10 that the sensor of rectifying (not shown in the figure for detecting and feeding back the skew of strap) and strap bilateral symmetry set up, and the strap passes between this correction board 10, when the sensor of rectifying detects the strap and takes place the skew, the correction board 10 of control corresponding side interferes the strap, makes it return just, after the strap returns just, the board 10 return of rectifying. Preferably, the deviation rectifying plate 10 is controlled by a servo motor to move along a linear guide rail 92, and the heating roller is further connected with a hot air system 13.

Since the tape itself has the adhesive, it is necessary to heat the adhesive to soften and wind it on the mandrel 100 to increase the winding force, so that the heating operation is performed on the tape by the heating roller before winding. After the heating is finished, the cloth belt is guided by the wire nozzle device 4 and is conveyed to the mandrel 100 for winding.

The winding mechanism comprises a second guide rail base 6 parallel to the first guide rail base 1, a left jacking mechanism 7 is vertically arranged at one end of the second guide rail base 6, a right jacking mechanism 8 which is identical to the left jacking mechanism 7 in structure is arranged on the second guide rail base 6 in a sliding mode towards the left jacking mechanism 7, and a mandrel 100 used for winding is jacked between the left jacking mechanism 7 and the right jacking mechanism 8. The distance between the right tightening mechanism 8 and the left tightening mechanism 7 is adjusted through sliding of the right tightening mechanism to tighten and clamp mandrels 100 with different lengths. The mandrel 100 has a problem that the overall length is slightly changed due to thermal expansion and contraction under the change of temperature, and the winding quality is affected by avoiding the change of the rotation speed of the mandrel 100 caused by the change of the pushing force of the mandrel 100 due to the problem. Preferably, the left jacking mechanism 7 and the right jacking mechanism 8 are both structures of a lathe chuck box, sensors (not shown in the figure) are arranged at jacking positions at two ends, and the functions of automatic real-time display and compensation of jacking force are realized in the workpiece cooling process, and the compensation distance is 20mm at the maximum value. The real-time measurement to the tight mechanism of top to the system control right side tight mechanism 8 is for the removal of the tight mechanism 7 of left top, and makes the tight force of top to dabber 100 invariable, thereby guarantees the invariant of rotational speed, improves winding quality. The left tightening mechanism 7 and the right tightening mechanism 8 are controlled by a special headstock servo, so that the positioning precision is high, the bearing capacity is high, the operation is stable and reliable, and the guarantee is provided for ensuring the winding precision and the winding quality.

In the process of stranding a plurality of fiber yarns, the tension of the stranded fiber yarns is different due to the inconsistent pay-off speed of each fiber disc, the fiber yarns which are broken by excessive tension and the fiber yarns which are not tensioned by too small tension exist, and the stranded quality is poor. In order to make each fiber yarn have the same tension, an adjusting device for fiber paying-off tension constant is provided in the fiber sand rack 2, and comprises a tension sensor (not shown in the figure), a servo motor 21, and a spiral roller 22 with a continuous roller groove 22a connected to the rotating shaft of the servo motor 21. The paying-off tension of each fiber yarn is detected through a tension sensor, the paying-off tension is fed back to the servo motor 21 to be adjusted, and the tension of the fiber yarns is adjusted through acceleration or deceleration of the servo motor 21. The fiber is wound on the continuous roller groove 22a of the spiral roller 22, and the friction between the fiber and the spiral roller 22 is increased by continuously winding the fiber on the continuous roller groove 22a, so that the synchronism of the fiber and the spiral roller is improved, and the servo motor 21 can accurately adjust the tension of the fiber. Each fiber yarn has the same tension when being stranded, and the strand forming quality is improved. Preferably, in order to further improve the synchronization between the fiber and the spiral roller 22 and improve the precision of the adjustment of the servo motor 21, the continuous roller groove 22a has a gradual structure (as shown in fig. 4) with a large diameter at both sides and a small diameter at the middle along the axial direction of the spiral roller 22, and compared with the roller grooves with the same diameter, the continuous roller groove has different winding diameters because the fiber is wound in the roller grooves with different diameters, so that the fiber is prevented from sliding between the adjacent roller grooves, the synchronization between the fiber and the spiral roller 22 is further improved, and the precision of the tension adjustment of the servo motor 21 is further improved. Preferably, the servo motor 21 can be replaced by a magnetic powder brake to apply braking action to the fiber or other winding materials as required.

The winding of the stranded fiber on the mandrel 100 has multiple routing modes, so that the nozzle device 4 has adaptive flexibility, the nozzle device 4 comprises a cylinder 41 which is opposite to the roller 52 fixedly arranged on one side of the triangular bracket 51 and has a hollow structure, the cylinder 41 is close to one side of the winding mechanism and is sequentially provided with a rotating mechanism (preferably a servo motor, not shown in the figure) and an anti-falling device for preventing fiber from slipping towards the direction of the winding mechanism, and the other side of the cylinder 41 is fixedly provided with a front end anti-falling device (shown as iv in fig. 7) which has the same structure as the anti-falling device. The strand of fiber that passes through the tensioning of elasticity weight 53 loops through front end anticreep device, barrel 41 and anticreep device earlier and twines on dabber 100, and the anticreep device drives rotatory guide fiber strand nimble winding on dabber 10 through servo motor. Because the fibre thigh has the process of marcing forward always when the winding, the change of walking the line is walked in the cooperation winding again, has the process of displacement in the space, consequently, the anticreep device can effectively prevent the change of fibre thigh displacement and the problem of slippage for 4 whole ability control fibre thigh's trends of silk mouth device improve the accuracy nature of the line of winding. The front end anti-slip device provides guidance and anti-slip of the fiber strands into the barrel 41. The cylinder 41 can rotate freely in 360 degrees, so that no obstacle exists in an operation area, and the safety during operation is greatly improved.

Specifically, the anti-disengaging device includes that perpendicular symmetry sets up the backup pad 42 in rotary mechanism one side, transversely is equipped with leading wheel 43 and anti-disengaging wheelset 44 between backup pad 42, anti-disengaging wheelset 44 is including laminating rolling first action wheel 44a and second action wheel 44b, and the running roller groove between them all establishes to be close with planar structure's cambered surface 44 c. In the cavity 101 that the fibre thigh constitutes through the roller groove of first action wheel 44a and second action wheel 44b, because the roller groove of first action wheel 44a and second action wheel 44b is the cambered surface 44c that is close with planar structure, cavity 101 that consequently constitutes can effectively be inside fibre thigh (its strip structure for having certain width) restriction, prevent when winding circuit changes, the fibre thigh is the easy problem of turning round (fibre thigh laminating is at cambered surface 44c, because cambered surface 44 c's structural feature, the both sides height is middle low, can prevent the lateral sliding of fibre thigh in the roller groove), influence the planarization of twining on dabber 100. In order to reduce the friction and wear of the roller grooves to the fiber strands, the roller grooves and the fiber strands are preferably synchronously transmitted through the matching of the gear tooth grooves, and the first driving wheel 44a and the second driving wheel 44b in synchronous transmission can avoid the friction and wear problem caused by the restraining rotation of the fiber strands to the wheel body which rotates slowly.

For the weight of winding the fibre thigh on the accurate control dabber 100, the tight mechanism 7 in left side top all is equipped with the structure the same and is used for dabber 100 to twine measuring weighing device 9 in real time with the tight mechanism 8 inboard in right side top, it can twine the weight on the dabber 100 by real-time measurement, so that can in time stop the winding when reaching rated winding weight, not only save fibre thigh material, also effectively prevent to twine unnecessary fibre thigh to the dabber 100 simultaneously, the difficult problem of getting rid of in later stage (because fibre thigh soaks glues, twine the difficult removal on the dabber 100). And the real-time measurement mode also solves the problem of tedious weighing due to multiple times of shutdown, and reduces redundant workload.

Specifically, the weighing device 9 includes a scale 91 arranged at the bottom of the inner side of the left tightening mechanism 7 and the right tightening mechanism 8, and a sliding support device for the mandrel 100 is arranged at the top end of the scale 91 along the tightening direction of the mandrel 100. The mandrel 100 is supported by the sliding support device, and then both ends of the mandrel 100 are tightly pressed by the left pressing mechanism 7 and the right pressing mechanism 8 (the pressing action does not have the support for the mandrel 100 in the vertical direction, and is only used for keeping the pressing force of the mandrel 100 under the temperature change constant and keeping the rotating speed constant, thereby facilitating the winding of the fiber strand). When the mandrel 100 is subjected to temperature change, the two ends of the mandrel can horizontally slide under the supporting action of the sliding supporting device without influencing weight measurement. Therefore, the weighing device 9 has the function of measuring the weight in real time and simultaneously has the function of allowing the mandrel 100 to change along with the temperature.

Preferably, the sliding support means includes a linear slide rail 92 provided on the scale 91 in the tightening direction of the mandrel 100 and a U-shaped bracket 93 sliding thereon. And flat rollers 94 for supporting and rotating both ends of the core shaft 100 are provided at both sides of the bottom in the U-shaped bracket 93. Therefore, the sliding support device has the function of facilitating the movement of the mandrel 100 due to temperature changes on the basis of real-time measurement.

In order to provide the mandrel 100 with a high levelness after being jacked up, so as to improve the winding quality. The front end of the screw nozzle device 4 is provided with a marking plate 11. After the mandrel 100 is tightly jacked, marking marks are marked on two ends of the mandrel 100 through the marking plate 11, and the jacking levelness of the mandrel 100 is further determined, so that the winding quality is improved.
