Description

Technical Field

[0001] This utility model relates to the field of fabric production, and in particular to a hot pressing forming device for fabric processing. Background Technology

[0002] Non-elastic fabrics (such as wool, cotton-linen, and polyester blends) require thermoforming processes in garment manufacturing to achieve specific silhouettes and three-dimensional structures, in order to meet the design requirements of high-end clothing for drape, crispness, and clean lines. Thermoforming, through precise control of temperature, pressure, and time, causes the fiber molecular chains to recombine and solidify, giving the fabric a stable geometric shape (such as neckline creases and placket hems), while retaining its natural properties of moisture absorption, breathability, and soft touch. It is a key processing step that balances aesthetics and functionality.

[0003] Chinese Utility Model Patent Publication No. CN214736719U discloses a hot pressing molding machine for fabric processing, including a support mechanism for supporting a storage box, a storage mechanism for storing different types of molds, and a molding mechanism for hot pressing the fabric. The storage mechanism is installed above the support mechanism, and the molding mechanism is fixed above the storage mechanism. This utility model, by incorporating the storage mechanism, allows the storage box to store different types of molds, improving the functionality and practicality of the device.

[0004] The aforementioned prior art achieves thermoforming of fabric by pressing a heating plate into a mold. However, since the fabric being formed is pressed into the mold cavity, it is not easy to remove the fabric after thermoforming, which makes loading and unloading inconvenient and affects efficiency.

[0005] Therefore, it is necessary to propose a hot pressing forming device for fabric processing to solve the above problems. Utility Model Content

The top of the linkage lifting plate 8 is provided with a guide block corresponding to the drive arms 13. A corresponding auxiliary plate 9 is provided, and a guide groove assembly is provided on the side wall of the auxiliary plate 9. A guide block 14 is used to move and guide the guide groove assembly. The guide groove assembly is configured such that when the auxiliary plate 9 moves down, the mold plate 5 remains stationary, and when the mold plate 5 moves up, the mold plate 5 first opens and then closes. In a preferred embodiment, the guide groove assembly includes a vertical guide groove 19 provided on one side of the auxiliary plate 9. A first inclined guide groove 20 is provided at the upper end of the vertical guide groove 19, and a second inclined guide groove 21 is provided at the lower end. The ends of the first inclined guide groove 20 and the second inclined guide groove 21 that are away from the vertical guide groove 19 correspond to the ends of the vertical guide groove 19. The vertical guide groove 19, the first inclined guide groove 20, and the second inclined guide groove 21 form a closed loop mechanism. The guide block 14 interacts with the vertical guide groove 19, the first inclined guide groove 20, and the second inclined guide groove 21. In the guiding mechanism, the first inclined guide groove 20 is provided with a slope 23 at one end near the vertical guide groove 19 and at the lower end of the vertical guide groove 19. The upper end of the vertical guide groove 19 and the second inclined guide groove 21 are provided with a step 22 corresponding to the slope 23. A recess with a depth greater than that of the vertical guide groove 19, the first inclined guide groove 20, and the second inclined guide groove 21 is formed between the step 22 and the corresponding slope 23. In order to accommodate the step 22 and the slope 23, a blind hole 24 corresponding to the guide block 14 is provided on the lower side wall of the drive arm 13. One end of the guide block 14 is movably connected to the inside of the blind hole 24. An elastic element 25 is provided between the inside of the blind hole 24 and one end of the guide block 14. The elastic element 25 is preferably a spring.

[0030] In order to guide the mold plate 5, side plates 6 corresponding to the mold plate 5 are provided around the top of the frame 1. Guide rods 7 are provided on the side plates 6. The mold plate 5 is provided with a first guide hole 16 corresponding to and adapted to the guide rod 7 on the side near the side plate 6. The guide rod 7 passes through the first guide hole 16 and is movably guided and engaged with the first guide hole 16.

[0031] To further facilitate loading and unloading operations, a first positioning plate 10 corresponding to one of the side plates 6 is provided at one end of the top of the frame 1. A first positioning socket 11 is provided at the bottom of the side plate 6 corresponding to the first positioning plate 10. The first positioning plate 10 is movably inserted into the first positioning socket 11. A second positioning plate 15 is provided at the upper end of the drive arm 13 corresponding to the first positioning plate 10. A second positioning socket 12 adapted to the second positioning plate 15 is provided at the bottom of the mold plate 5 corresponding to the second positioning plate 15. The second positioning plate 15 is inserted into the second positioning socket 12.

[0032] In use, the four mold plates 5 are in a combined state. The fabric to be formed is placed in the space enclosed by the four mold plates 5. Initially, the guide block 14 is located in the recess between the lower step 22 and the slope 23. The control drive source 3 drives the lifting frame 4, the column 27, and the linkage lifting plate 8 to move down synchronously. The guide block 14 enters the vertical guide groove 19 through the lower slope 23 and the elastic element 25 retracts. During this stage, the drive arm 13 and the mold plates 5 remain stationary. The heating plate 26 enters the space enclosed by the four mold plates 5 to achieve heat pressing. The guide block 14 will pass through the upper step 22 and fall into the recess between the upper step 22 and the slope 23. The elastic element 25 resets at this time. After the heat pressing is completed, the drive source 3 drives the lifting frame 4, the column 27, and the linkage lifting plate 8 to rise synchronously. At this time, the auxiliary plate 9 rises along with it. The guide block 14 is on the upper step. Under the restriction of 22 and the guidance of slope 23, it will enter the first inclined guide groove 20 through slope 23. The elastic element 25 will retract again. At this stage, the drive arm 13 will drive the mold plate 5 to move outward and open, so as to remove the formed fabric. Then, the new fabric will be fixed. After that, the drive source 3 will continue to raise the auxiliary plate 9. The guide block 14 will enter the second inclined guide groove 21 from the first inclined guide groove 20. The drive arm 13 will drive the mold plate 5 to merge until the guide block 14 enters the depression between the lower step 22 and slope 23. The elastic element 25 will reset. Then, the hot pressing work can be repeated. In addition, in order to further facilitate loading and unloading, one side of the mold plate 5 and side plate 6 can be removed upward, so that the first positioning insert 10 is separated from the first positioning insert 11, and the second positioning insert 15 is separated from the second positioning insert 12.
