Description

Technical Field

[0001] This utility model relates to the field of bag manufacturing technology, specifically a bag sewing positioning mold. Background Technology

[0002] In the bag manufacturing industry, a bag is generally made up of several pieces of fabric sewn together in certain positions. To improve the appearance of the bag, fabric with logos, patterns and other markings is usually sewn onto the outer and inner surfaces of the bag. In addition, for the overall aesthetics, the flap of the bag is also sewn into an arc shape. Currently, the sewing and fixing of various parts to improve the appearance of the bag is purely done by manual positioning and sewing.

[0003] The existing patent with publication number CN219861869U proposes a sewing positioning mold for bags. The mold is sewn and fixed, which, compared with the traditional manual positioning and sewing, can quickly, accurately and uniformly fix the fabric and sew multiple layers of fabric together.

[0004] However, when sewing the base fabric at the bottom of the bag, the existing molds cannot quickly squeeze and fix the base fabric around the perimeter, resulting in slow sewing efficiency for the base fabric at the bottom of the bag. Utility Model Content

[0005] The purpose of this invention is to provide a sewing positioning mold for bags, so as to solve the problem that existing molds cannot quickly squeeze and fix the bottom base fabric of bags, resulting in slow sewing efficiency of the bottom base fabric.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewing positioning mold for a bag, including a first base, a second base fixedly disposed at the front end of the first base, overlapping plates fixedly disposed on the inner walls of both the second base and the first base, a mold component placed on the upper end of the two overlapping plates, a sewing groove opened on the inner wall of the mold component, a hidden groove opened on one side of the upper end of the first base and one side of the upper end of the second base, a quick locking structure provided inside the two hidden grooves, the quick locking structure including an adjusting plate slidably disposed inside the hidden groove, a fastening rod fixedly disposed on the side of the adjusting plate near the mold component, and locking holes opened on both sides of the mold component located on the side of the two fastening rods; Two sets of fastening rods are inserted into two corresponding locking holes to achieve a fixed connection between the first base, the second base and the stacking plate.

[0007] Furthermore, an adjustment structure is provided between the first base and the second base. The adjustment structure includes sliding rods fixedly disposed on both sides of the rear end of the second base, a sliding groove is provided at the front end of the first base located at the rear end of the sliding rods, a screw is threaded on the upper end of the first base, and an adapter hole is provided at the upper end of the sliding rods.

[0008] Furthermore, limiting blocks are fixedly installed on both sides of the two sets of sliding rods, and the sliding rods are limited to slide within the sliding groove.

[0009] Furthermore, elastic elements are provided at both the front and rear ends of one side of the adjustment plate, and one side of the elastic element is fixedly connected to the inner wall of one side of the hidden groove.

[0010] Furthermore, the elastic element is a spring.

[0011] Furthermore, a crossbar is rotatably provided on one side of the upper end of the mold component.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1) By setting up a quick-locking structure, when the mold is used to squeeze and fix the base fabric at the top of the lap board, the mold can be fixedly assembled with the first base and the second base, which can improve the sewing efficiency when sewing the edge of the base fabric.

[0013] 2) By setting and adjusting the structure, when it is necessary to place mold parts of different sizes, the size can be adapted by adjusting the distance between the first base and the second base, thereby improving the overall application range of the mold. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Combination Figures 1-4 A sewing positioning mold for a bag includes a first base 1, a second base 2 fixedly disposed at the front end of the first base 1, and overlapping plates 3 fixedly disposed on the inner walls of both the second base 2 and the first base 1. A mold component 4 is placed on the upper end of the two overlapping plates 3. A sewing groove 5 is provided on the inner wall of the mold component 4. A hidden groove 6 is provided on one side of the upper end of the first base 1 and one side of the upper end of the second base 2. A quick locking structure 7 is provided inside the two hidden grooves 6. The quick locking structure 7 includes an adjusting plate 8 slidably disposed inside the hidden groove 6. A fastening rod 9 is fixedly disposed on the side of the adjusting plate 8 near the mold component 4. Locking holes 11 are provided on both sides of the mold component 4 located on the side of the two fastening rods 9. Two sets of fastening rods 9 are inserted into two corresponding locking holes 11 to achieve a fixed connection between the first base 1, the second base 2 and the stacking plate 3.

[0018] See Figure 3 and Figure 4 Furthermore, it is found that both sides of the two sets of sliding rods 13 are fixedly provided with limiting blocks, the sliding rods 13 are located inside the sliding groove 14 and are limited to slide, and the front and rear ends of one side of the adjusting plate 8 are provided with elastic elements 10, one side of the elastic element 10 is fixedly connected to the inner wall of one side of the hidden groove 6, the elastic element 10 is a spring, and a crossbar is rotatably provided on one side of the upper end of the mold part 4.

[0019] Specifically, the limiting block can prevent the rear end of the sliding rod 13 from being directly pulled out from the sliding groove 14, and the elastic element 10 can reset the adjusting plate 8 to ensure that the mold part 4 is fixed at the upper end of the stacking plate 3.

[0020] Example 2 See Figure 4 Furthermore, based on Embodiment 1, an adjustment structure 12 is provided between the first base 1 and the second base 2. The adjustment structure 12 includes sliding rods 13 fixedly arranged on both sides of the rear end of the second base 2. A sliding groove 14 is provided at the front end of the first base 1 located at the rear end of the sliding rods 13. A screw 15 is threaded on the upper end of the first base 1. An adapter hole 16 is provided at the upper end of the sliding rods 13.

[0021] Specifically, the sliding rod 13 is used to slide inside the sliding groove 14, thereby adjusting the distance between the first base 1 and the second base 2. After the screw 15 enters the interior of the adapter hole 16, it can achieve the tightening of the first base 1 and the second base 2 after the distance is adjusted.

[0022] In actual operation, when it is necessary to sew the base fabric of the bag bottom, put the fabric to be sewn on the upper end of the overlay plate 3, and simultaneously pull the adjusting plate 8 with both hands, so that the adjusting plate 8 squeezes the spring. The mold part 4 covers the upper end of the base fabric, thereby achieving the fastening of the edge of the base fabric. The sewing needle is used to sew the base fabric of the bag bottom against the inner wall of the sewing groove 5, which speeds up the sewing efficiency and avoids the separation of multiple layers of base fabric during the sewing process.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
