Abstract
Description
Technical Field
[0001] This utility model relates to the field of hook and loop fastener technology, and more specifically, to a hook and loop fastener forming equipment. Background Technology
[0002] Hook and loop fasteners, commonly known as Velcro, are fastening devices made of two different fabrics: one side has dense hooks, and the other side has soft fibers. The invention of hook and loop fasteners was inspired by nature. In 1948, Swiss engineer Georges de Mestral noticed while hunting that his clothes and his dog's fur were covered with burdock seeds. The hooks on these seeds allowed them to adhere firmly to the clothing. After research, de Mestral discovered that this structure could be used to create a new type of fastener. After years of experimentation, he successfully invented hook and loop fasteners. Since its invention, hook and loop fasteners have been rapidly and widely used in various fields due to their unique adhesive properties.
[0003] Traditional hook and loop fastener processing and shaping equipment may be inconvenient to process hook and loop fasteners of different widths and sizes due to its relatively simple structure. During the cutting process, the shape and size of the cut hook and loop fasteners may change due to offset during transportation. At the same time, it is not convenient to adjust the tension of the hook and loop fasteners during feeding and conveying, which may cause the hook and loop fasteners to loosen during feeding, thus reducing their practicality. Utility Model Content

[0029] Please see Figure 1-5 A hook and loop fastener forming device includes a workbench 1, a limiting device and a cutter 2 on the workbench 1, a moving device on the workbench 1, a guide frame 3 on the moving device, a pressing sleeve 4 on the guide frame 3, a pressing spring 5 inside the pressing sleeve 4, a pressing plate 6 at one end of the pressing spring 5, a guide wheel 7 on the pressing plate 6, a support seat 8 on one side of the workbench 1, a rotating shaft 9 on the support seat 8, a rotating roller 10 on the rotating shaft 9, a friction ring 11 on the rotating shaft 9, a support plate 12 on the support seat 8, a support rod 13 on the support plate 12, a friction plate 14 at one end of the support rod 13, a support spring 15 between the friction plate 14 and the support plate 12, a positioning shaft 27 on the rotating roller 10, a positioning groove 28 on the rotating shaft 9, an installation rod 29 on the rotating shaft 9, and an installation nut 30 at one end of the installation rod 29.
[0030] In this embodiment, during the cutting and forming of the hook and loop fastener, a rotating roller 10, on which the hook and loop fastener is wound, is mounted on a rotating shaft 9. The positioning shaft 27 of the rotating roller 10 is inserted into the positioning groove 28 of the rotating shaft 9. The rotating roller 10 and the rotating shaft 9 are connected and installed through the cooperation of the mounting rod 29 and the mounting nut 30. Then, one end of the hook and loop fastener is passed through the limiting device, the guiding device, and the cutter 2 in sequence. Driven by the driving action of one end of the hook and loop fastener, the hook and loop fastener moves between the guiding device and the limiting device. At the same time, the hook and loop fastener drives the rotating roller 10 to rotate. When the rotating roller 10 rotates, it drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 causes the friction ring 11 to slide relative to the friction plate 14. The support spring 15 provides a continuous and stable elastic force to the friction plate 14, thereby slowing down the rotation of the rotating shaft 9 and preventing the rotating roller 10 from rotating too fast and causing the hook and loop fastener to loosen. The forming equipment can be maintained according to the wear of the friction ring 11 and the friction plate 14, making the operation convenient.
[0031] Please see Figure 1 and Figure 5As one embodiment of the limiting device and the moving device: the moving device includes a moving groove 16, which is symmetrically arranged on the worktable 1. A moving block 17 is slidably arranged in the moving groove 16. A guide frame 3 is fixedly arranged on the moving block 17. A moving screw 18 is provided on the worktable 1. The moving screw 18 is provided with symmetrical and opposite threads and is threadedly connected to the moving block 17. A moving knob 19 is provided at one end of the moving screw 18. The limiting device includes a limiting frame 20, which is symmetrically arranged on the worktable 1. A limiting roller 21 is rotatably arranged between the limiting frames 20. A limiting groove 22 is provided on the limiting frame 20. A limiting block 23 is slidably arranged on the limiting groove 22. The limiting roller 21 is rotatably arranged on the limiting block 23. A limiting screw 24 is provided between one limiting block 23 and the limiting frame 20. A limiting slide bar 25 is provided between the other limiting block 23 and the limiting frame 20. An anti-slip protrusion 26 is provided on the limiting roller 21.
[0032] More specifically, based on the width of the hook and loop fastener, rotating the movement knob 19 causes the movement screw 18 to rotate, which in turn causes the movement block 17 to move in opposite directions within the movement groove 16, thereby adjusting the spacing of the guide frame 3. To adjust the height of the limiting roller 21 as needed, rotating the limiting screw 24 causes the limiting block 23 to move within the limiting groove 22, thereby adjusting the height of the limiting roller 21. When the hook and loop fastener passes through the limiting roller 21, the anti-slip protrusion 26 prevents it from slipping and shifting. Simultaneously, after entering the guiding device, the guide wheel 7 on the pressure plate 6 guides the movement of the hook and loop fastener, preventing it from shifting on the worktable 1 and ensuring that the hook and loop fastener enters the cutter 2 accurately.
[0033] In summary, during the use or operation of the overall equipment: when cutting and forming hook and loop fasteners, the rotating roller 10, which is wrapped around the hook and loop fastener, is installed on the rotating shaft 9. The positioning shaft 27 of the rotating roller 10 is inserted into the positioning groove 28 of the rotating shaft 9. The rotating roller 10 and the rotating shaft 9 are connected and installed through the cooperation of the mounting rod 29 and the mounting nut 30. Then, one end of the hook and loop fastener is passed through the limiting device, the guiding device and the cutter 2 in sequence. Through the driving action of one end of the hook and loop fastener, the hook and loop fastener moves between the guiding device and the limiting device. At the same time, the hook and loop fastener drives the rotating roller 10 to rotate. When the rotating roller 10 rotates, it drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 causes the friction ring 11 to slide relative to the friction plate 14. The support spring 15 provides a continuous and stable elastic force to the friction plate 14, thereby slowing down the rotation of the rotating shaft 9 and preventing the rotating roller 10 from rotating too fast and causing the hook and loop fastener to loosen. The forming equipment can be maintained according to the wear of the friction ring 11 and the friction plate 14. The operation is convenient.
[0034] According to the width of the hook and loop fastener, rotate the moving knob 19. The moving knob 19 drives the moving screw 18 to rotate. The moving screw 18 drives the moving block 17 to move in opposite directions within the moving groove 16, thereby adjusting the spacing of the guide frame 3. To adjust the height of the limiting roller 21 as needed, rotate the limiting screw 24. The limiting screw 24 drives the limiting block 23 to move within the limiting groove 22, thereby adjusting the height of the limiting roller 21. When the hook and loop fastener passes through the limiting roller 21, the anti-slip protrusion 26 prevents the hook and loop fastener from slipping and deviating. At the same time, after the hook and loop fastener enters the guiding device, the guide wheel 7 on the pressure plate 6 guides the movement of the hook and loop fastener, preventing the hook and loop fastener from deviating on the worktable 1, so that the hook and loop fastener enters the cutter 2 in an accurate position.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
