Description

Technical Field

[0001] This utility model relates to the field of hook and loop fastening technology, specifically to a material pairing structure of a hook and loop fastening device. Background Technology

[0002] Velcro is a common connecting accessory used in clothing, bags, toys and other products. It is fixed by bonding the male and female sides. In order to improve the rigidity of Velcro products and the ease of use, a base layer needs to be sewn on its working side (male or female side).

[0003] Currently, hook and loop fastener sewing is mostly done manually. Workers take raw materials from a basket, align the working surface with the base surface, stack them together, and then sew them together using a sewing device to complete the production of the hook and loop fastener product. With the continuous increase in labor costs, production costs are constantly rising. Furthermore, due to differences in worker skills and proficiency, the consistency of hook and loop fastener products is easily affected. Manual sewing is costly, labor-intensive, inefficient, and results in inconsistent product quality. Therefore, there is a need to design automated hook and loop fastener sewing equipment. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies and to disclose to the public a material pairing structure for a Velcro sewing device that has a reasonable structure, can achieve the alignment and stacking of the working surface and the base surface, and can improve processing efficiency.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A material pairing structure for a Velcro sewing device includes a frame, on which a feeding tray assembly is mounted. A working fabric tray and a base fabric tray are coaxially mounted on the feeding tray assembly. A working surface conveying channel is located on the frame opposite the working fabric tray, and a base surface conveying channel is located on the frame opposite the base fabric tray. The working surface conveying channel and the base surface conveying channel are parallel to each other. A working surface cutting device is located on the working surface conveying channel, and a base surface cutting device is located on the base surface conveying channel. A working surface conveying gripper is located beside the working surface conveying channel, and a pre-fixing mechanism and a product conveying gripper are located beside the base surface conveying channel.

[0007] Further optimization measures for this technical solution are as follows:

[0008] As an improvement, the working face cutting device includes a first cutting cylinder, a first cutting head connected to the first cutting cylinder, and a first clearance groove provided on the working face conveying channel directly opposite the position of the first cutting head.

[0009] As an improvement, the base surface cutting device includes a second cutting cylinder, a second cutting head is connected to the second cutting cylinder, and a second clearance groove is provided on the base surface conveying channel opposite the position of the second cutting head.

The working surface conveying gripper moves the cut working surface horizontally above the base surface, causing the working surface and base surface to overlap.

[0011] As an improvement, the pre-fixing mechanism includes a third lifting cylinder, on which a pre-fixing block is fixed. The pre-fixing mechanism is used for fixing when the base surface is cut.

[0012] As an improvement, a limiting step is provided at the bottom of the pre-fixed block. The limiting step is used to limit the base surface, thereby achieving the purpose of conveying and positioning.

[0014] As an improvement, the product conveying gripper includes a conveying guide rail fixed to the frame, a second slider slidably fitted on the conveying guide rail, a fourth lifting cylinder fixed on the second slider, a second mounting base connected to the fourth lifting cylinder, a second fixed head and a fifth lifting cylinder provided on the second mounting base, and a second movable head cooperating with the second fixed head connected to the fifth lifting cylinder. The product conveying gripper conveys the stacked working surfaces and base surfaces together to the sewing process for stitching.

[0015] As an improvement, a connecting plate is connected to the second slider, the connecting plate is connected to the conveyor belt, and the conveyor belt is wound around two rotating wheels, one of which is connected to a drive motor.

[0016] The advantages of this utility model compared with the prior art are:

[0017] This utility model discloses a material alignment structure for a hook and loop fastener sewing device. The structure is rationally designed, using parallel conveying channels for the working surface and the base surface to transport them respectively. A corresponding cutting device cuts both the working and base surfaces. Then, a working surface conveying gripper moves the cut working surface onto the base surface, stacking them together. Finally, a product conveying gripper transports the stacked working and base surfaces together to the sewing process for stitching. This achieves automatic alignment, stacking, and feeding of the working and base surfaces, thus automating the processing of hook and loop fastener products. It effectively improves production efficiency, product consistency, and reduces the labor intensity of workers. Attached Figure Description

A working surface conveying gripper 5 is located beside the working surface conveying channel 11, and a pre-fixing mechanism 6 and a product conveying gripper 7 are located beside the base surface conveying channel 12.

[0034] The working face cutting device 3 includes a first cutting cylinder 31, a first cutting head 32 connected to the first cutting cylinder 31, and a first clearance groove 11a provided on the working face conveying channel 11 directly opposite the position of the first cutting head 32.

[0035] The base surface cutting device 4 includes a second cutting cylinder 41, a second cutting head 42 connected to the second cutting cylinder 41, and a second clearance groove 12a provided on the base surface conveying channel 12 directly opposite the position of the second cutting head 42.

[0036] The working surface webbing is cut by the working surface cutting device 3, and the base surface webbing is cut by the base surface cutting device 4.

[0037] The working surface conveying gripper 5 includes a translational track 51 fixed to the frame 1. A first slider 52 is slidably fitted on the translational track 51. A translational cylinder 53 is connected to the first slider 52. A first lifting cylinder 54 is fixed on the slider 52. A first mounting base 55 is connected to the first lifting cylinder 54. A first fixing head 56 and a second lifting cylinder 57 are provided on the first mounting base 55. A first movable head 58 that cooperates with the first fixing head 56 is connected to the second lifting cylinder 57. The working surface cut by the working surface conveying gripper 5 is translated to above the base surface, so that the working surface and the base surface are stacked together.

[0038] The pre-fixing mechanism 6 includes a third lifting cylinder 61, on which a pre-fixing block 62 is fixed.

[0039] The bottom end of the pre-fixed block 62 is provided with a limiting step 62a. The limiting step 62a is used to achieve conveying and positioning, so that the base surface is conveyed to the set position.

[0040] A mounting bracket 63 is fixed on the frame 1, and the third lifting cylinder 61 is fixed to the mounting bracket 63. The mounting bracket 63 facilitates the installation of the third lifting cylinder 61.

[0041] When cutting the base surface, the end of the base surface webbing is fixed by the pre-fixing mechanism 6 to facilitate the cutting of the base surface cutting device 4.

[0042] The product conveying gripper 7 includes a conveying guide rail 71 fixed to the frame 1. A second slider 72 is slidably fitted on the conveying guide rail 71. A fourth lifting cylinder 73 is fixed on the second slider 72. A second mounting base 74 is connected to the fourth lifting cylinder 73. A second fixed head 75 and a fifth lifting cylinder 76 are provided on the second mounting base 74. A second movable head 77 that cooperates with the second fixed head 75 is connected to the fifth lifting cylinder 76. The function of the product conveying gripper 7 is to convey the stacked working surfaces and base surfaces together to the sewing process for sewing.

[0043] A connecting plate 81 is connected to the second slider 72. The connecting plate 81 is connected to the conveyor belt 82, which is wound around two rotating wheels 83. One of the rotating wheels 83 is connected to a drive motor 84. The drive motor 84 drives the rotating wheel 83 to rotate, thereby driving the conveyor belt 82 to move, which in turn drives the second slider 72 to move along the conveyor guide rail 71 via the connecting plate 81.

[0044] Working principle:

[0045] The working face webbing is placed on the working face fabric tray 21, and the base face webbing is placed on the base face fabric tray 22. The working face fabric tray 21 and the base face fabric tray 22 are coaxially arranged so that the working face and the base face are pulled out to the same length. The working face is conveyed on the working face conveying channel 11 and cut by the working face cutting device 3. When cutting the working face, the working face conveying jaws 5 clamp the end of the working face. The base face is conveyed on the base face conveying channel 12 and cut by the base face cutting device 4. When cutting the base face, the pre-fixing mechanism 6 presses down on the end face of the base face.

[0046] The working surface conveying gripper 5 clamps the cut working surface. The working surface conveying gripper 5 controls the lifting and lowering of the first movable head 58 through the second lifting cylinder 57. The working surface is clamped by the cooperation of the first movable head 58 and the first fixed head 56. The first slider 52 is moved along the translation track 51 by the translation cylinder 53, so that the gripper is moved as a whole, thereby moving the working surface to the base surface conveying channel 12 (at the same time, the third lifting cylinder 61 drives the pre-fixed block 62 to rise to avoid it), aligning the working surface with the base surface, or stacking the working surface on the base surface.

[0047] Then, the product conveying gripper 7 operates, transferring the working surface and the base surface together to the sewing process for sewing. The product conveying gripper 7 controls the lifting and lowering of the second movable head 77 through the fifth lifting cylinder 76. The clamping function is achieved through the cooperation of the second movable head 77 and the second fixed head 75. After the gripper clamps the working surface and the base surface, the drive motor 84 is started to drive the second slider 72 to move along the conveying guide rail 71 to achieve conveying.

[0048] The material matching structure of this utility model's hook and loop fastener sewing device enables automatic alignment, stacking, and conveying of the working surface and the base surface, thereby achieving automated processing of hook and loop fastener products. This effectively improves production efficiency, enhances product consistency, and reduces the labor intensity of workers.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
