Description

Technical Field

[0001] This utility model relates to the field of hook and loop fastener winding technology, and more specifically, it relates to an adjustable hook and loop fastener winding machine. Background Technology

[0002] Hook and loop fasteners are a type of fabric fastener consisting of hook and loop sides on both sides. They are widely used in clothing, footwear, medical supplies, and other fields. Their main function is to achieve quick fastening and easy removal through the adhesion of the hook and loop sides. They are characterized by ease of operation, high reusability, and wide applicability.

[0003] During the production and processing of hook and loop fasteners, they need to be wound up for storage and transportation. Existing hook and loop fastener winding machines are not convenient for adjusting the winding length of the winding shaft for hook and loop fasteners of different widths, thus making it inconvenient to wind up hook and loop fasteners of different models and widths, resulting in poor flexibility in use.

[0008] An easily adjustable Velcro rewinding machine includes a frame, a ball screw at the rear of the frame, a screw motor in cooperation with the ball screw, a screw nut on the ball screw, a rewinding motor on the screw nut, a rewinding shaft at the output end of the rewinding motor, a rewinding groove on the rewinding shaft, a telescopic groove on the frame to cooperate with the rewinding shaft, first cylinders on both sides of the screw nut, mounting brackets at the top of the first cylinders, a pressure shaft in front of the mounting brackets to cooperate with the rewinding shaft, multiple pressure rollers on the pressure shaft via bearings, the pressure rollers being located above the rewinding shaft, and a moving groove on the frame to cooperate with the pressure rollers.

[0009] The present invention is further configured such that two sets of support wheels are symmetrically arranged at the front of the frame, the two sets of support wheels are located on both sides below the winding shaft, and a synchronous opposing adjustment component is provided between the two sets of support wheels. The support wheels can press and support the bottom of the hook and loop fastener during the winding process, thereby improving the winding effect of the hook and loop fastener.

[0010] The present invention is further configured such that the synchronous opposing adjustment component includes a support frame, a bidirectional screw is provided on the support frame, and a drive motor is provided in cooperation with the bidirectional screw. A drive block is threaded on the bidirectional screw, and the support wheel is installed on the corresponding drive block.

[0011] The present invention is further configured such that a second cylinder is provided on the drive block, a support frame is provided at the top of the second cylinder, and the support wheel is mounted on the support frame through a bearing. The lifting and lowering of the support frame can be controlled by the second cylinder, thereby realizing the lifting and lowering adjustment of the support wheel during use.

[0012] The present invention is further configured such that limit rods are provided at both ends of the bidirectional screw, and the driving block is slidably sleeved on the limit rods. The limit rods can limit the movement of the driving block, thereby improving the movement stability of the driving block.

[0013] The present invention is further configured such that a limiting shaft is provided at the tail end of the pressing shaft, and a limiting roller is provided on the limiting shaft via a bearing. The cooperation of the limiting shaft and the limiting roller can limit the hook and loop fastener during winding, improve the stability of the hook and loop fastener during winding, and avoid the situation of unwinding or tangling.

Loosening the locking element can realize the flexible adjustment of the installation angle of the limiting shaft on the pressing shaft.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides an adjustable Velcro winding machine with the following advantages:

[0018] 1. This utility model incorporates a ball screw and mounts a winding motor, which drives the winding shaft to rotate during the winding of the hook and loop fastener, on the screw nut. In operation, the screw motor is activated, controlling the ball screw's movement. This allows the screw nut to control the movement of the winding motor, enabling the winding shaft to extend outward through the telescopic groove to the outside of the frame. By controlling the movement of the screw nut, the length of the winding shaft extending out of the frame for winding can be controlled. This allows the winding shaft to extend to different lengths depending on the width of the hook and loop fastener to be wound, improving the flexibility of hook and loop fastener winding.

[0019] 2. Simultaneously, this utility model provides a pressing shaft above the take-up shaft, and multiple pressing rollers are mounted on the pressing shaft in conjunction with the take-up shaft. The pressing shaft is mounted on a screw nut via a mounting bracket and a first cylinder, allowing the position of the pressing rollers to be adjusted synchronously with the position of the take-up shaft. Thus, when the extension length of the take-up shaft changes, the pressing rollers will also move accordingly, ensuring the pressing of Velcro of different widths during take-up. In this utility model, multiple pressing rollers are provided, so unused pressing rollers will not rotate, reducing rotational resistance and wear on equipment parts. During the take-up process, the operation of the first cylinder can be controlled, causing the mounting bracket to drive the pressing shaft to descend, and the pressing shaft to drive the pressing rollers to descend, thereby pressing the Velcro roll located on the take-up shaft and improving the take-up effect of Velcro.

[0020] 3. This utility model has support wheels on both sides below the winding shaft. In use, the drive motor can be started, which controls the rotation of the bidirectional screw. Under the threaded engagement of the drive block and the bidirectional screw, and the sliding limit action of the drive block and the limit rod, the two sets of drive blocks can be controlled to move synchronously in opposite directions. This can drive the corresponding support frame to move, thereby adjusting the distance between the two sets of support wheels. This allows for flexible adjustment of the support position according to the thickness of the wound hook and loop fastener roll. At the same time, the second cylinder can be started, which controls the raising and lowering of the support wheels, so that the support wheels can press and support the bottom of the wound hook and loop fastener roll, thereby achieving bottom pressing support during the hook and loop fastener winding process and improving the tightness of the winding.

[0031] Furthermore, this utility model has two sets of support wheels 14 symmetrically arranged in front of the frame 1. The two sets of support wheels 14 are located on both sides below the winding shaft 6. A synchronous opposing adjustment component is provided between the two sets of support wheels 14. The support wheels 14 can press and support the bottom of the Velcro during the winding process, thereby improving the winding effect of the Velcro.

[0032] Specifically, the synchronous opposing adjustment assembly includes a support frame 15, on which a bidirectional screw 16 is provided, and a drive motor 17 is provided in conjunction with the bidirectional screw 16. A drive block 18 is threaded on the bidirectional screw 16, and a support wheel 14 is mounted on the corresponding drive block 18. The bidirectional screw 16 is rotated by the drive motor 17, so that the drive block 18 can move synchronously in opposite directions on the support frame 15, thereby realizing the movement adjustment of the support wheel 14.

[0033] Furthermore, the present invention provides a second cylinder 19 on the drive block 18, and a support frame 20 is provided at the top of the second cylinder 19. The support wheel 14 is mounted on the support frame 20 through bearings. The second cylinder 19 can control the lifting and lowering of the support frame 20, thereby realizing the lifting and lowering adjustment of the support wheel 14 during use.

[0034] Please see Figures 1-5 As one implementation of the drive block 18: the two ends of the bidirectional screw 16 are provided with limit rods 21, and the drive block 18 is slidably sleeved on the limit rods 21. The drive block 18 can be moved and limited by the limit rods 21, thereby improving the movement stability of the drive block 18.

[0035] Please see Figures 1-5 As one embodiment of the pressing shaft 11: a limiting shaft 22 is provided at the tail end of the pressing shaft 11, and a limiting roller 23 is provided on the limiting shaft 22 through a bearing. The cooperation of the limiting shaft 22 and the limiting roller 23 can limit the hook and loop fastener during winding, improve the stability of the hook and loop fastener during winding, and avoid the situation of unwinding or messy winding. The setting of the limiting roller 23 can reduce the sliding friction between the limiting shaft 22 and the hook and loop fastener.

[0036] Please see Figures 1-5As one implementation of the limiting shaft 22: a connector 24 is provided at the top of the limiting shaft 22, and a connecting groove 25 is provided on the connector 24.

Tightening the locking member 26 can lock the connector 24 on the pressing shaft 11, thereby realizing the installation and fixation of the limiting shaft 22 on the pressing shaft 11. Loosening the locking member 26 can flexibly adjust the installation angle of the limiting shaft 22 on the pressing shaft 11.

[0037] In summary:

[0038] This invention features a ball screw 2 and a winding motor 5, which drives the winding shaft 6 to rotate during the winding of the Velcro, mounted on a screw nut 4 on the ball screw 2. In use, the screw motor 3 can be started, controlling the operation of the ball screw 2. This allows the screw nut 4 to control the movement of the winding motor 5, enabling the winding shaft 6 to extend outward through the telescopic groove 8 to the outside of the frame 1. By controlling the movement of the screw nut 4, the length of the winding shaft 6 extending out of the frame 1 for winding can be controlled. This allows the winding shaft 6 to extend to different lengths depending on the width of the Velcro to be wound, improving the flexibility of Velcro winding.

[0039] Meanwhile, this utility model provides a pressing shaft 11 above the take-up shaft 6, and multiple pressing wheels 12 are provided on the pressing shaft 11 in conjunction with the take-up shaft 6. The pressing shaft 11 is mounted on the screw nut 4 through the cooperation of the mounting bracket 10 and the first cylinder 9. This allows the position of the pressing wheels 12 to be adjusted synchronously with the position of the take-up shaft 6. Thus, when the extension length of the take-up shaft 6 changes, the pressing wheels 12 will also move accordingly, thereby ensuring the pressing of Velcro of different widths during winding. In this utility model, multiple pressing wheels 12 are provided, so that unused pressing wheels 12 will not rotate, reducing rotational resistance and wear of equipment parts. During the winding process, the operation of the first cylinder 9 can be controlled, so that the mounting bracket 10 drives the pressing shaft 11 to descend, and the pressing shaft 11 drives the pressing wheels 12 to descend, thereby pressing the Velcro roll located on the take-up shaft 6 and improving the winding effect of Velcro.

[0040] This invention features support wheels 14 on both sides below the winding shaft 6. During use, the drive motor 17 is activated, controlling the rotation of the bidirectional screw 16. Through the threaded engagement of the drive block 18 and the bidirectional screw 16, and the sliding limit action between the drive block 18 and the limiting rod 21, the two sets of drive blocks 18 can be controlled to move synchronously towards each other. This drives the corresponding support frame 20 to move, thereby adjusting the distance between the two sets of support wheels 14. This allows for flexible adjustment of the support position based on the thickness of the wound hook and loop fastener roll. Simultaneously, the second cylinder 19 is activated, controlling the raising and lowering of the support wheels 14. This allows the support wheels 14 to press firmly against the bottom of the wound hook and loop fastener roll, achieving bottom pressure support during the winding process and improving the tightness of the hook and loop fastener roll.
