Description

Technical Field

[0001] This utility model relates to the field of home textile production technology, specifically a double-needle overlapping and pressing 2.5 cm elastic and rolled edge integrated mold. Background Technology

[0002] During the production of home textile products, some customers have put forward specific process requirements for products such as fitted sheets: they require the use of 2.5 cm wide elastic bands, of which 1 cm is sewn and fixed by a double needle machine, and the remaining 1.5 cm of elastic bands are exposed, and the elasticity ratio of the elastic bands must reach 1:2.2 or higher.

[0003] However, in existing technologies, hemming and elastic band installation in home textile sewing are usually two separate processes, lacking integrated equipment capable of simultaneously achieving precise hemming and elastic band positioning and elasticity control. Using traditional processing methods not only requires operators to frequently switch processes and repeatedly position the elastic bands, resulting in high labor intensity and low production efficiency, but also easily leads to problems such as inconsistent hemming width, uncontrolled elasticity ratio of the elastic band, and sewing position deviation. This results in unstable product quality, a high error rate, and an inability to meet specific customer process requirements, thus affecting order acceptance. Therefore, there is an urgent need to develop an integrated mold adapted to this process requirement to overcome the shortcomings of existing technologies. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, the purpose of this invention is to provide a double-needle overlapping 2.5 cm elastic band and rolled edge integrated mold, so as to realize the integrated sewing of rolled edge treatment and elastic band installation, reduce the labor intensity of operators, reduce the error rate, stabilize product quality, accurately control the elasticity ratio of elastic band, improve labor efficiency, and meet customer process requirements.

[0006] Furthermore, the number of guide posts is two, and the distance between the two guide posts is 2.5cm.

[0007] Furthermore, a rectangular hole is provided inside the mounting base plate, and a third bolt is fitted onto both the inner wall of the rectangular hole and the upper surface of the mounting base plate.

[0008] Furthermore, a rectangular tube is fixedly connected to the upper surface of the rectangular ring, a pressing plate is slidably connected to the inner wall of the rectangular tube, a rubber pad is adhered to the bottom of the pressing plate, a spring is fixedly connected to the upper surface of the pressing plate, and a horizontal plate is fixedly connected to the upper surface of both the spring and the upper surface of the rectangular tube.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, this utility model of a double-needle overlapping 2.5 cm tensioning and curling integrated mold includes a mounting base plate 1. A T-shaped plate 2 is attached to the upper surface of the mounting base plate 1. A first circular hole 3 is opened inside the T-shaped plate 2. A first bolt 4 is attached to both the inner wall of the first circular hole 3 and the upper surface of the T-shaped plate 2. A first threaded hole 5 is opened inside the mounting base plate 1. The inner wall of the first threaded hole 5 is threadedly connected to the surface of the first bolt 4. A guide post 6 is fixedly connected to the upper surface of the T-shaped plate 2. A rectangular ring 7 is connected to the upper surface of the guide post 6. A support plate 8 is attached to the upper surface of the mounting base plate 1. A second circular hole 9 is provided on the upper surface. A second bolt 10 is attached to the inner wall of the second circular hole 9 and the upper surface of the support plate 8. A second threaded hole 11 is provided inside the mounting base plate 1. The inner wall of the second threaded hole 11 is threaded to the surface of the second bolt 10. A rolled edge folding plate 12 is fixedly connected to the bottom of the support plate 8. A rectangular hole 13 is provided inside the mounting base plate 1. A third bolt 14 is attached to the inner wall of the rectangular hole 13 and the upper surface of the mounting base plate 1. Positioning blocks 22 are attached to both the front and rear sides of the support plate 8. The bottom of the positioning blocks 22 is fixedly connected to the upper surface of the mounting base plate 1.

[0024] There are two guide posts 6, and the distance between the two guide posts 6 is 2.5cm.

[0025] It should be noted that the T-shaped plate 2 can be fixed on the mounting base plate 1 by the cooperation of the first round hole 3, the first bolt 4 and the first threaded hole 5. When the 2.5cm elastic band is inserted between the two guide posts 6, the guide posts 6 and the rectangular ring 7 can guide and position the 2.5cm elastic band. The support plate 8 can be fixed on the mounting base plate 1 by the cooperation of the second round hole 9, the second bolt 10 and the second threaded hole 11. At the same time, the support plate 8 is provided with two second round holes 9. By aligning the second round holes 9 at different positions with the second threaded hole 11, the position of the hem folding plate 12 can be changed. At the same time, the positioning block 22 can position the support plate 8 and ensure that the hem folding plate 12 will not tilt. The hem folding plate 12 is used to hem the cut pieces with a width of 1 cm, ensuring that the hem width is accurately controlled at 1 cm, reducing manual positioning errors, reducing the probability of errors and stabilizing product quality.

[0026] A rectangular tube 15 is fixedly connected to the upper surface of the rectangular ring 7. A pressing plate 16 is slidably connected to the inner wall of the rectangular tube 15. A rubber pad 17 is glued to the bottom of the pressing plate 16. A spring 18 is fixedly connected to the upper surface of the pressing plate 16. A horizontal plate 19 is fixedly connected to the upper surface of both the spring 18 and the upper surface of the rectangular tube 15. A third threaded hole 20 is opened inside the horizontal plate 19. A fourth bolt 21 is threadedly connected to the inner wall of the third threaded hole 20. The bottom of the fourth bolt 21 is in contact with the upper surface of the pressing plate 16.

[0027] Among them, the upward pulling force of the spring 18 on the pressing plate 16 is greater than the sum of the weights of the pressing plate 16 and the rubber pad 17, and the rubber pad 17 is located between the left and right guide posts 6.

[0028] It should be noted that the pressing plate 16 can slide up and down within the rectangular tube 15. The tension of the pressing plate 16 by the spring 18 ensures that the pressing plate 16 can make close contact with the fourth bolt 21. When the user rotates the fourth bolt 21, the fourth bolt 21 can move up or down through the cooperation between the fourth bolt 21 and the third threaded hole 20, which changes the pressure of the rubber pad 17 on the elastic band. At this time, the friction between the rubber pad 17 and the elastic band stabilizes and controls the elasticity ratio to 1:2.2 or higher, meeting the specific process requirements of the customer and solving the problem of uncontrolled elasticity ratio in traditional processing.

[0029] The working process of this utility model is as follows: (a) Place the mounting base plate 1 on the sewing machine table and adjust the position of the third bolt 14 in the rectangular hole 13 according to the preset distance between the cut piece and the needle. Then, fix the mounting base plate 1 on the sewing machine table by means of the third bolt 14.

[0030] (b) Place the T-shaped plate 2 on the mounting base plate 1 and align the first round hole 3 with the first threaded hole 5. Then, pass the first bolt 4 through the first round hole 3 and screw it into the first threaded hole 5. At this time, the T-shaped plate 2 is fixed on the mounting base plate 1 by the cooperation of the first round hole 3, the first bolt 4 and the first threaded hole 5.

[0031] (c) Insert the 2.5cm elastic band between the two guide posts 6, and guide and position the elastic band through the rectangular ring 7 and the guide posts 6. Then, by rotating the fourth bolt 21, adjust the pressing force of the rubber pad 17 on the elastic band so that the elasticity ratio of the elastic band reaches the process requirement of 1:2.2 or higher. After the adjustment is completed, stop rotating the fourth bolt 21. At this time, the pressing force of the rubber pad 17 on the elastic band will no longer change due to the self-locking property between the fourth bolt 21 and the third threaded hole 20.

[0032] (d) Adjust the position of the hem folding plate 12 according to the distance between the cut piece and the needle. After adjustment, pass the second bolt 10 through the corresponding second round hole 9 and screw it into the second threaded hole 11. At this time, the hem folding plate 12 can be fixed in a suitable position by the cooperation of the second round hole 9, the second bolt 10 and the second threaded hole 11.

[0033] (e) The home textile piece to be sewn is placed into the inlet end of the hemming folding plate 12. The piece is automatically hemmed to a width of 1cm through the inner wall of the hemming folding plate 12 and then sent out from the outlet end.

[0034] (f) Start the double needle machine. The cut piece and the 2.5 cm elastic band after elasticity adjustment are fed synchronously. The double needle machine completes the 1 cm wide overlap stitching according to the preset trajectory, so that the elastic band and the rolled edge cut piece are firmly connected. Finally, the double needle overlap stitching of 2.5 cm elastic band plus rolled edge stitching is completed.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
