During the process, each pressure sensing device on the upper uniform output roller detects the reverse pressure of the fiber bundle at the corresponding position on the upper uniform output roller, and transmits the detected pressure value to the average pressure device to calculate along the The average pressure value of the apocynum fiber fed in the length direction of the upper uniform output roller. When the average pressure value is greater than the set pressure value, it means that the thickness of the output apocynum fiber bundle is too large. At this time, drive the motor to control the uniform output roller. The speed decreases, thereby reducing the feeding of the apocynum fiber bundle. When the average pressure value is less than the set pressure value, it means that the thickness of the output apocynum fiber bundle is too small. At this time, the speed of the uniform output roller under the control of the motor is increased. , so as to increase the feeding of the apocynum fiber clusters, and then realize the uniform output of the apocynum fiber clusters, and the evenly output apocynum fiber clusters are fed after being conveyed by the conveying curtain, so as to accept the counterclockwise movement of the front in a free state with a certain pressure The carding effect of the rotating third carding roller, during the carding process, the apocynum fiber clusters are sent into the third carding roller in the vertical direction to receive free opening, and the carding clothing of the third carding roller first touches the apron during the free opening process. The hemp fiber cluster is grasped with a certain thickness, and the opening effect between the fibers of a certain thickness is realized during the grasping process, and the captured apocynum fiber is gradually dispersed on the circumferential surface of the third carding roller rotating at high speed, and then realized. The gradual dispersion and opening effect of the apocynum fiber, along with the dispersion of the apocynum fiber on the surface of the third carding roller, the card clothing is gradually inserted between the fibers, and then the carding is realized. The fine carding effect of the hemp fiber, the apocynum fiber transferred to the third carding roller is supported by the small drain bottom to realize the rotation around the circumferential direction of the third carding roller, and the carding on the small drain bottom during the supporting process The carding clothing on the bar and the carding clothing on the third carding roller have a mutual tearing effect on the fibers so as to realize the carding effect on the fibers.

Under the combined action of the two The fibers in the apocynum fiber bundle are gradually transferred to the fourth carding roller by the third carding roller 7, and then the discretization of the fibers in the fiber bundle is realized in the step-by-step transfer process, thereby realizing the opening and closing in the free state during the transfer process. Loose effect, the cotton fiber transferred under the drive of the second carding roller is sent downward, and the apocynum fiber transferred under the drive of the fourth carding roller is sent upward, and the two fibers are then separated by the second carding roller and the fourth carding roller.

During the stripping and transfer process, the mixing of the two fibers is further realized. The mixed fibers on the fifth carding roller are subsequently The complete transfer to the sixth carding roller is realized under the action of the sixth carding roller that rotates clockwise in front, and the fibers on the sixth carding roller are carded by the movable cover plate that rotates counterclockwise after rotating to the upper arc surface The carding action of the opening card clothing on the sheet realizes the repeated transfer of the mixed fibers between the sixth carding roller and the movable flat plate under the action of the carding, and realizes the repeated carding action of the mixed fibers during the transfer process, and then makes the fibers The contact force between them is further reduced until they are decomposed into a single fiber state. At the same time, the fine mixing of the two fibers in the single fiber state is realized in the repeated transfer process of the fibers under the action of carding. The mixed fibers on the sixth carding roller are After detaching from the active area of the movable cover, it is subjected to the carding action of the card clothing on the seventh carding roller that rotates counterclockwise. The mixed fiber web is condensed on the seven carding rollers. The mixed fiber web is completely stripped by the stripping roller and then conveyed by the pressing roller pair. The output fiber web is then The mixed fiber raw sliver is gathered into a mixed fiber sliver through the bell mouth, and the mixed fiber raw sliver is continuously wound in the winding can after being pressed and shaped by the compacting roller pair through the coordinated rotation of the winding shaft and the winding can.

As a further preferred solution, in step 4, two drawing frames are adopted. In the first drawing drawing, raw mixed fiber slivers are fed together, and the raw mixed fiber slivers fed are first gathered together. During the gathering process, each mixed fiber The details and thick places on the raw sliver are randomly combined, so that the weight unevenness of the sliver can be improved during the random combination process, and the gathered sliver can be stretched by the drafting system to reduce the linear density to obtain a mixed fiber Half-cooked sliver, the straightness of the fibers in the sliver is improved during the drafting process; 8 mixed fiber half-cooked slivers are fed together in the second drawing, and the fed 8 mixed fiber half-cooked slivers are gathered and drafted in turn After stretching, mixed fiber cooked strips are obtained.

As a further preferred solution, in step five, during the large drafting process, the mixed fiber cooked sliver is drafted through a drafting system composed of four rollers and four long and short aprons, and the gripping effect between the rollers is relied on during the drafting process The external control force field jointly formed by the force and the friction field formed by the apron jaws controls the fibers in the mixed cooked sliver, so that the fibers in the mixed cooked sliver can achieve a relatively stable and concentrated speed change in the drafting area. The reduction of the linear density is achieved during the speed change process, and the fiber strands with the required linear density are obtained after drafting. The fiber strands are then transferred to each other under the action of the twisting degree. During the transfer process The mutual entanglement between the fibers is caused, and then a certain cohesion force is generated between the fibers, so as to obtain an antibacterial blended yarn with continuous distribution characteristics and a certain strength.

Compared with the prior art, the present invention feeds the apocynum fiber clumps into the mixing carding machine by opening and clearing the apocynum fibers with short fiber length and poor length uniformity, thereby avoiding the roll-making process of apocynum. , Feed the apocynum fiber bundle and the cotton fiber roll into the mixing carding machine in a free state and a holding state respectively, and after fully opening and carding independently, the two are mixed with each other through the carding action of a pair of carding rollers, In this way, the uniform mixing effect of the two can be realized, and the mixing effect of the two can be realized before the sliver is formed, so as to effectively overcome the difficulty that the apocynum fiber is difficult to form a sliver separately, and the mixed fiber cooked sliver can be directly formed into a yarn through a spinning frame with a large draft , thereby reducing the spinning process and greatly improving spinning efficiency.
