It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

Referring to FIGS. 1-7 , an automatic feeding unwinding storage device includes a feeding mechanism 1 for conveying coils, an unwinding mechanism 2 for driving the coils to rotate, a quilting machine 3 for sewing the head and tail ends of two coils together, and a storage rack 4. The unwinding mechanism 2 includes an unwinding frame 21 and a roller 22 rotatably connected to the unwinding frame 21 for driving the coils to rotate, and a rotating motor 23 for driving the roller 22 to rotate. A plurality of rollers 22 are provided, and the rollers 22 are arranged in parallel with each other. The rollers 22 are arranged in a U-shaped structure that can hold the coils. The unwinding frame 2 1 is connected with a lifting frame 24 in a sliding manner along its height direction, a roller 22 on the unwinding frame 21 close to the feeding port is rotatably connected to the lifting frame 24, and the unwinding frame 21 is also provided with a lifting driver 25 for driving the lifting frame 24 to slide on the unwinding frame 21; the feeding mechanism 1 includes a feeding frame 11, a conveyor belt 12 wound on the feeding frame 11, and a feeding driving device 13 for driving the conveyor belt 12 to rotate, the discharge port of the conveyor belt 12 is arranged corresponding to the feeding port of the unwinding frame 21, and the height of the discharge port of the conveyor belt 12 is not lower than the height of the feeding port of the unwinding frame 21.

The discharge port of the loading mechanism 1 is arranged correspondingly to the feed port of the unwinding mechanism 2, the discharge port of the unwinding mechanism 2 is arranged correspondingly to the feed port of the quilting machine 3, and the discharge port of the quilting machine 3 is arranged correspondingly to the feed port of the storage rack 4, thereby realizing the continuous connection of the conveying, unwinding, quilting and storage of the coiled material. Each roller 22 constitutes an unwinding position for holding the coil. When the rotating motor 23 drives the roller 22 to rotate, the coil thereon can be driven to rotate accordingly, thereby realizing feeding. The sliding setting of the lifting frame 24 can move the roller 22 on one side of the feed port, so as to facilitate the heavy coil to be directly dropped from the loading mechanism 1 to the unwinding position. The loading mechanism 1 drives the conveyor belt 12 to rotate through the loading drive device 13, which is convenient for moving the coil and directly dropping the coil from the discharge port of the loading mechanism 1 to the unwinding position. In this process, due to the downward sliding of the lifting frame 24, the roller 22 on the side of the feed port of the unwinding mechanism 2 can slide downward, which is convenient for the supply coil to be rolled into the unwinding position, rather than falling from the top of the unwinding position to the unwinding mechanism 2. Therefore, the coordinated use of the loading mechanism 1 and the unwinding mechanism 2 not only realizes the automatic loading of the coil and improves the degree of automation, but also can effectively prevent the coil from being damaged during transportation and placement, and greatly shortens the replacement time of the coil, thereby effectively improving work efficiency.

Among them, the quilting machine 3 is a well-known technology and adopts a common design; the lifting drive 25 can refer to the use of a cylinder, or can use a motor to drive a screw to achieve the sliding of the lifting frame 24 on the unwinding frame 21; and the feeding drive device 13 can refer to the use of a motor.

The rotating motor 23 is connected to the roller 22 rotatably connected to the unwinding frame 21, and the two adjacent rollers 22 rotatably connected to the unwinding frame 21 are connected to each other in the same direction. The rotating motor 23 is only connected to the roller 22 rotatably connected to the unwinding frame 21, so the roller 22 rotatably connected to the unwinding frame 21 serves as a driving wheel for driving the coil to rotate, and the roller 22 rotatably connected to the lifting frame 24 serves as a driven wheel for driving the coil to rotate. This structure is simple and easy to implement, and can drive the coil to rotate smoothly on the unwinding frame 21. This solution only needs to be provided with one motor to realize the rotation and feeding of the coil, and has good economic benefits; and the transmission connection structure can refer to the use of a synchronous belt or a synchronous chain.

Among the rollers 22 rotatably connected to the unwinding frame 21, two rollers 22 at the same height are arranged at the bottom. The two rollers 22 can facilitate the loading of the coil and place it at the unwinding position. In the process of driving the coil to rotate, the two rollers 22 at the same height can facilitate the smooth feeding of the coil.

The unwinding frame 21 is provided with a pushing plate 26 capable of pushing the coils to align, and a material pushing driving device 27 for driving the pushing plate 26 to move closer to or away from the coils at the ends of the coils. After the coils are placed at the unwinding position, the material pushing driving device 27 drives the pushing plate 26 to push the ends of the coils to align, which is beneficial for the later unloading of the coils. The material pushing driving device 27 can refer to the use of a cylinder.

A material pressing device 28 capable of pressing the sheet material sent out of the coil is provided on the side of the unwinding frame 21 near the discharge port. The material pressing device 28 includes a fixed rotating roller 281 rotatably connected to the unwinding frame 21, a material pressing slide 282 slidably connected to the unwinding frame 21, a movable rotating roller 283 rotatably connected to the material pressing slide 282, and a material pressing driver 284 for driving the material pressing slide 282 to slide on the unwinding frame 21. The fixed rotating roller 281 is arranged in parallel with the movable rotating roller 283, and the sliding direction of the material pressing slide 282 on the unwinding frame 21 is close to or away from the fixed rotating roller 281. The material pressing driver 284 drives the material pressing slide 282 to slide toward the fixed rotating roller 281, so that the movable rotating roller 283 can cooperate with the fixed rotating roller 281 to press the sheet material sent out of the coil. The material pressing driver 284 can refer to the use of a cylinder.

A discharge pressing block 29 for pressing the coil is provided on the unwinding frame 21 near the discharge port, and a contact wheel 291 capable of contacting the outer wall of the coil is rotatably connected to the discharge pressing block 29 toward the coil side, and a discharge port cylinder 292 is rotatably connected to the unwinding frame 21, and the discharge pressing block 29 is fixedly connected to the piston rod of the discharge port cylinder 292. The discharge pressing block 29 contacts the outer wall of the coil after the sheet material is sent out through the pressing device 28, which is convenient for the output of the sheet material, and the contact wheel 291 is provided on the discharge pressing block 29 to reduce the friction on the coil material and avoid scratches on the coil material, and the discharge port cylinder 292 is provided, and when the coil material gradually reduces its diameter after continuous feeding, the discharge pressing block 29 can be sent out through the discharge port cylinder 292, and it is always in contact with the outer wall of the coil material.

The conveyor belt 12 is provided with a limit strip 121 for limiting the rolling of the coil, and a plurality of limit strips 121 are provided, and each limit strip 121 is arranged along the length direction of the conveyor belt 12. The limit strips 121 are arranged in parallel, and the coil is located between two adjacent limit strips 121. The limit strip 121 can abut against the circumferential outer side wall of the coil to limit the rolling of the coil on the conveyor belt 12, which is conducive to improving the stability of the coil during transportation.

A winding roller 41 for winding material around is rotatably connected to the storage rack 4, and a plurality of winding rollers 41 are arranged on the upper and lower sides of the storage rack 4, and the winding rollers 41 are arranged in parallel. A storage slide 42 for installing the winding roller 41 is slidably connected to the storage rack 4 near the discharge port, and several winding rollers 41 on the lower side of the storage rack 4 near the discharge port are rotatably connected to the storage slide 42, and the sliding direction of the storage slide 42 on the storage rack 4 is the height direction of the storage rack 4. An induction switch for detecting the position of the storage slide 42 is arranged on the storage rack 4, and a feeding device 43 for feeding the stitched material is provided at the feeding end of the storage rack 4, and a discharging device 44 for feeding out the material that has bypassed the winding roller 41 is provided at the discharging end of the storage rack 4. After the coil of the quilting machine 3 is fed into the feeding device 43, it is wound on the winding roller 41. The implementation method of winding the coil on the winding roller 41 can be expressed as the coil winding around the winding roller 41 on the upper side of the storage rack 4, then around the winding roller 41 on the lower side of the storage rack 4, and then around the winding roller 41 on the upper side of the storage rack 4. This is repeated so that the coil is wound into a snake shape and finally sent out from the discharging device 44. The coil can be processed by processing equipment or wound up by a receiving device.

While the coil is being wound and conveyed on the storage rack 4, when the discharging speed of the discharging device 44 is greater than the feeding speed of the feeding device 43, the length of the coil wound on the winding roller 41 will be shortened, thereby driving the storage slide 42 to slide upward until the storage slide 42 is detected by the induction switch. The feeding speed of the feeding device 43 and/or the discharging speed of the discharging device 44 can be adjusted to ensure that the coil can be delivered stably and continuously. When the length of the coil wound on the storage rack 4 is restored, the storage slide 42 will slide downward under the action of gravity to restore the original settings of the feeding device 43 and/or the discharging device 44.

The feeding device 43 and the discharging device 44 both include a fixed feeding roller 45 and a dynamic feeding roller 46 rotatably connected to the storage rack 4, and a feeding driver 47 for driving the dynamic feeding roller 46 to rotate. The fixed feeding roller 45 and the dynamic feeding roller 46 are arranged in parallel for clamping and conveying the material. The fixed feeding roller 45 and the dynamic feeding roller 46 are clamped on both sides of the thickness direction of the coil respectively, and the feeding driver 47 drives the dynamic feeding roller 46 to rotate to realize the conveying of the coil. The structure is simple and easy to implement, and the conveying force on the coil is directly applied to the coil, which is conducive to improving the stability of the coil conveying.

A storage slide 48 for installing winding rollers 41 is provided on the storage rack 4 near the feed port. Several winding rollers 41 on the upper or lower side of the storage rack 4 near the feed port are rotatably connected to the storage slide 48. The sliding direction of the storage slide 48 on the storage rack 4 is the height direction of the storage rack 4. The storage rack 4 is provided with a lifting drive device 49 for driving the storage slide 48 to slide longitudinally on the storage rack 4. During the continuous feeding process of the discharging device 44, when the coil on the unwinding mechanism 2 is being replaced, the feeding device 43 cannot continue to feed the coil into the storage rack 4. After the storage slide 42 is detected by the induction switch, the lifting drive device 49 can drive the storage slide 48 to slide on the storage rack 4, shortening the distance between the winding roller 41 on the storage rack 4 and the winding roller 41 on the storage slide 48, so that the coil can be continuously released for the continuous operation of the discharging device 44. After the coil is replaced, the feeding speed of the feeding device 43 can be adjusted, and after the lifting drive device 49 drives the storage slide 48 to reset, the feeding speed of the feeding device 43 can be restored to match the discharging speed of the discharging device 44. The storage slide 48 greatly improves the automation of the storage rack 4, which can be conducive to the continuous transportation of the coil.

The lifting drive device 49 can refer to the use of a screw rod threaded on the storage slide 48 and a motor for driving the screw rod to rotate. The length direction of the screw rod is consistent with the sliding direction of the storage slide 48. When the motor drives the screw rod to rotate, the storage slide 48 can be driven to slide on the storage rack 4.
