[0012] Preferably, the upper template is also provided with a first handle groove for facilitating lifting of the upper template.

[0013] Preferably, a second handle groove for facilitating lifting of the positioning plate is provided on the positioning plate of the lower template.

[0014] The beneficial effects of the utility model are:

[0015] (1) The slide rail and sliding plate design of the upper template provide a stable channel for the sewing machine presser foot, avoiding direct contact between the sewing needle and the Velcro fiber, making it difficult for the sewing needle to hook the Velcro fiber during sewing, thereby reducing the risk of thread breakage and Velcro damage.

[0016] (2) The positioning plate and gasket on the lower template provide precise positioning for sewing Velcro. After the slot of the positioning plate is aligned with the Velcro, the Velcro is fixed in the predetermined position and will not move even during the sewing process, ensuring the accurate alignment of the Velcro and improving the quality of the finished product.

[0017] (3) By setting marking lines and gaskets on the lower template, operators are provided with clear instructions to help them accurately place clothing and Velcro. This effective positioning mechanism reduces the number of times the operator adjusts the position of the Velcro during the sewing process, reduces workload, and improves production efficiency.

[0021] The present invention is further described below in conjunction with the accompanying drawings and examples, but these specific implementation schemes do not limit the protection scope of the present invention in any way.

[0022] Example 1

[0023] like Figure 1-2 As shown, a positioning mold for sewing Velcro comprises an upper template 1 and a lower template 2 connected to the upper template 1 by folding adhesive tape, a positioning plate 3 is also movably connected to the lower template 2, a slot 4 identical to the Velcro is provided on the positioning plate 3, after the positioning plate 3 is flipped over, the slot 4 is aligned with the Velcro for placement; a notch 5 aligned with the Velcro placement position is provided on the upper template 1, a slide rail 6 is provided on the notch 5, a slidable slide plate 7 is provided in the slide rail 6, a positioning groove 8 is provided on the slide plate 7, and the presser foot of a sewing machine moves the positioning groove 8 to sew the Velcro.

[0024] The technical effects that can be achieved by the above technical solution include:

[0025] By providing a positioning plate 3 on the lower template 2 and a slot 4 on the positioning plate 3 which is the same shape as the Velcro, accurate placement of the Velcro during the sewing process is ensured, and the flipping mechanism of the positioning plate 3 enables the slot 4 to be aligned with the Velcro, thereby avoiding movement of the Velcro during the sewing process and improving sewing accuracy.

[0026] The design of the slide rail 6 and the sliding slide plate 7 on the upper template 1 provides a stable channel for the sewing machine presser foot. The sewing machine presser foot moves through the positioning groove 8, and can directly sew the Velcro according to a fixed movement trajectory, which also reduces the risk of thread breakage and Velcro damage.

[0027] In this embodiment, the slide rail 6 is arranged on the top of the upper template 1, which is closed on three sides and open on one side. There is a slide groove between the slide rail 6 and the upper template 1. The slide plate 7 placed in the slide groove is a horizontally movable rectangular long plate, which is used to reduce the displacement of the slide plate 7 caused by machine vibration or improper operation during the sewing process, thereby ensuring the stability of the sewing process.

[0028] The rectangular long plate is provided with at least one long strip positioning groove 8 perpendicular to the direction of the slide rail 6. In this embodiment, the number of the long strip positioning grooves 8 is two, and the length of the long strip positioning groove 8 is greater than the width of the notch 5 of the upper template 1 and the slot 4 on the positioning plate 3. The horizontally movable rectangular long plate placed in the slide groove, with the long strip positioning groove 8 perpendicular to the direction of the slide rail 6, can assist the sewing machine presser foot of the sewing machine to move in the vertical direction, thereby accurately controlling the sewing path.

[0029] The lower template 2 is provided with a marking line 9 for placing clothes and at least one gasket 10 for marking the placement position of the Velcro. In this embodiment, there are two gaskets 10, which are arranged on the lower template 2 on the left and the right and have different shapes.

[0030] The marking line 9 and the gasket 10 provided on the lower template 2 provide clear instructions for the operator to help them accurately place the clothes and Velcro, while the gasket 10 reduces the time required for alignment and positioning before sewing, thereby improving the efficiency of the entire sewing process.

[0031] In this embodiment, the upper template 1 is provided with two first handle grooves 11 for facilitating lifting of the upper template 1 , and the positioning plate 3 of the lower template 2 is provided with two second handle grooves 12 for facilitating lifting of the positioning plate 3 .

[0032] The working principle and method of the positioning mold for sewing Velcro are as follows:

[0033] First, the operator lays the clothes flat on the lower template 2, and uses the marking lines 9 and gaskets 10 on the lower template 2 to accurately place the clothes and Velcro. The shape design of the gasket 10 helps to fix the Velcro, and can be combined with the positioning plate 3 to ensure that it does not move during sewing.

[0034] Secondly, the operator covers the positioning plate 3 and inserts the Velcro into the slot 4, so that the Velcro is fixed in the correct position.

[0035] Again, cover the upper template 1, align the notch 5 of the upper template 1 with the Velcro, place the entire mold under the sewing machine presser foot of the sewing machine, and start the sewing machine.

[0036] Finally, the sewing machine presser foot passes through the long strip positioning groove 8 on the slide plate 7, and drives the long strip positioning groove 8 to move horizontally along the slide rail 6, and sews the Velcro according to the preset sewing track.

[0037] The above shows and describes the basic principles, main features and advantages of the invention. Those skilled in the art should understand that the invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the invention.
