[0044] According to some embodiments of this application, please refer to Figures 1 to 6 This embodiment relates to a Velcro bag flap sewing template, including a base plate 1, a middle cover plate 2, and a top cover plate 3. The base plate 1 is provided with a bag flap placement area 11. The middle cover plate 2 is hinged to the base plate 1 and is positioned opposite to the bag flap placement area 11. The shape of the middle cover plate 2 is adapted to the bag flap placement area 11. The middle cover plate 2 is provided with at least one Velcro placement hole 21. One side of the top cover plate 3 is hinged to the base plate 1. The top cover plate 3 is provided with a Velcro processing hole 31, which is positioned opposite to the Velcro placement hole 21. The top cover plate 3 is also provided with a laser processing hole 32, which is positioned relative to the outer shape of the middle cover plate 2.
[0045] In this embodiment, four bag cover placement areas 11 are arranged on the base plate 1. The bag cover placement area 11 is a bag cover placement hole, and the bag cover placement hole positions the bag cover.
[0046] The middle cover plate 2 is hinged to the base plate 1. The middle cover plate 2 is set in the bag cover placement hole. There is a gap between the middle cover plate 2 and the bag cover placement hole. Four middle cover plates 2 are hinged on the base plate 1. One bag cover placement area 11 corresponds to one middle cover plate 2. The middle cover plate 2 presses the bag cover. There are two arranged hook and loop fastener placement holes 21 on the middle cover plate 2. The hook and loop fastener placement holes 21 position the hook and loop fastener.
[0047] Simply place the bag flap into the bag flap placement hole, cover it with the middle cover plate 2, then place two Velcro patches in the two Velcro placement holes 21 of the middle cover plate 2, and cover it with the top cover plate 3 to sew the two Velcro patches onto the bag flap.
[0048] In this embodiment, two top cover plates 3 are hinged to the base plate 1, such as... Figure 4 As shown, the two top cover plates 3 can be designed as double doors. The top cover plates 3 are provided with four Velcro processing holes 31 and two laser processing holes 32.
[0049] In this embodiment, the Velcro processing hole 31, the Velcro placement hole 21, and the bag cap placement hole are arranged from top to bottom. The textile head fixes two Velcro patches onto a bag cap. This embodiment can process four bag caps.
[0050] After sewing two Velcro straps onto the bag flap, open the top cover 3, place the bag flap inside on top of the middle cover, then close the top cover 3 and sew the bag flap inside onto the bag flap.
[0051] The gap between the laser-processed hole 32, the intermediate cover plate 2 and the bag cap placement hole is set from top to bottom. The laser cuts the inside of the bag cap and the edge of the bag cap along the gap between the laser-processed hole 32, the intermediate cover plate 2 and the bag cap placement hole.
[0052] After processing, turn the side with the Velcro facing out.
[0053] In this way, by completing the hook and loop fastener stitching and laser trimming in one go using the hook and loop bag flap stitching template, the sewing difficulty is reduced, no conversion is required, the process is simplified, and production efficiency is improved. This template, when used in the structural design of stitching hook and loop fasteners on the four corner bag flaps, saves 27 seconds per piece, increasing efficiency by 40% in this process.
[0054] According to some embodiments of this application, optionally, the middle cover plate 2 is provided with two hook and loop fastener placement holes 21, located on both sides of the middle cover plate 2, and the top cover plate 3 is provided with two hook and loop fastener processing holes 31 opposite to each other. In this way, two hook and loop fasteners can be sewn onto the bag flap at the same time, improving production efficiency.
[0055] According to some embodiments of this application, optionally, the cross-sectional shape of the hook and loop fastener placement hole 21 and the hook and loop fastener processing hole 31 is rectangular, and the size of the hook and loop fastener placement hole 21 is adapted to the size of the hook and loop fastener processing hole 31. In this way, by adapting the size and shape of the hook and loop fastener placement hole 21 to the size and shape of the hook and loop fastener processing hole 31, it is convenient for the textile head to sew the hook and loop fastener onto the bag flap.
[0056] According to some embodiments of this application, optionally, the bag cap placement area 11 is a bag cap placement hole, and the intermediate cover plate 2 is hinged within the bag cap placement hole. Thus, the bag cap within the bag cap placement area 11 can be fixed by the intermediate cover plate 2.
[0057] According to some embodiments of this application, optionally, the base plate 1 is provided with two or more bag flap placement areas 11, and the base plate 1 is correspondingly provided with two or more intermediate cover plates 2, with one intermediate cover plate 2 corresponding to one bag flap placement area 11. In this way, through two or more bag flap placement areas 11, two or more bag flaps can be sewn simultaneously, improving production efficiency.
[0058] According to some embodiments of this application, optionally, the base plate 1 is provided with four bag flap placement areas 11, and the Velcro bag flap sewing template is provided with two top cover plates 3, one of which is hinged to one side of the base plate 1 and the other is hinged to the other side of the base plate 1, with each top cover plate 3 corresponding to two bag flap placement areas 11. Thus, with four bag flap placement areas 11 and each top cover plate 3 corresponding to two bag flap placement areas 11, it is convenient to fix the bag flaps and improve production efficiency.
[0059] According to some embodiments of this application, optionally, the cross-sectional shape of the laser-processed hole 32 is adapted to the cross-sectional shape of the intermediate cover plate 2. Thus, the shape of the laser-processed hole 32 is set along the outer edge of the intermediate cover plate 2, which facilitates the laser-processed hole 32 to process the bag cap and the inside of the bag cap along the outer edge of the intermediate cover plate 2.
[0060] According to some embodiments of this application, optionally, the base plate 1, the intermediate cover plate 2, and the top cover plate 3 are all made of transparent material. This allows for easy viewing during the processing through the base plate 1, the intermediate cover plate 2, and the top cover plate 3.
[0061] Unlike existing technologies, the technical solution of this application features a bag cap placement area 11 on a base plate 1, with a middle cover plate 2 hinged to the base plate 1. The middle cover plate 2 has a Velcro placement hole 21, and one side of the cover plate is hinged to the base plate 1. The cover plate has a Velcro processing hole 31 and a laser processing hole 32, with the laser processing hole 32 shaped relative to the outer side of the middle cover plate 2. In use, a bag cap 5 is placed in the bag cap placement area 11, the middle cover plate 2 is closed, and the bag cap 5 is pressed down. The Velcro placement hole on the middle cover plate 2 is then... Place the Velcro 4 inside the hole 21, cover it with the top cover plate 3, and sew the Velcro 4 onto the bag flap 5 using a sewing head; open the top cover plate 3, place the bag flap liner on the middle cover plate 2, cover it with the top cover plate 3, and sew the four sides of the bag flap liner onto the four sides of the bag flap 5 using a sewing head; then use a laser head to laser trim the edges of the bag flap liner and the bag flap 5; in this way, by completing the sewing of the Velcro 4 and the laser trimming on the Velcro bag flap sewing template in one go, the sewing difficulty is reduced, no conversion is required, the process is simplified, and the production efficiency is improved.
[0062] Secondly, this embodiment also relates to a Velcro bag flap sewing device, including a Velcro bag flap sewing template as described in any of the above.
[0063] Velcro bag flap sewing equipment also includes a textile head and a laser head. The specific principles of the textile head and laser head are existing technologies and will not be elaborated here.
