Description

Technical Field

[0001] This utility model relates to the field of hot pressing technology for shoe uppers, specifically a hot pressing seamless bonding device for multi-layer composite flyknit shoe uppers. Background Technology

[0002] Flyknit uppers are a type of knitting technology controlled by computer programming. Through the integrated weaving of special yarns and computerized flat knitting machines, the upper is lightweight, breathable, and conforms well to the foot, making it widely used in athletic shoes. As a new generation of upper material, flyknit uppers achieve a sophisticated microstructure design thanks to their unique nanotechnology polymer treatment. This innovative material not only significantly improves the breathability and comfort of athletic shoes but also gives the upper excellent strength and elasticity. Specifically, the core characteristics of flyknit uppers include: extreme lightweight for effortless movement; high breathability to keep feet dry and cool; a comfortable fit with elastic material that tightly wraps the feet, enhancing the natural feel of walking; stylish and attractive with a variety of colors and patterns to meet individual needs; and stable support with high-strength material ensuring foot safety during exercise. Furthermore, flyknit uppers are suitable for various outdoor sports, running, fitness, and everyday casual wear. When maintaining them, avoid using strong corrosive cleaning agents; clean gently and keep the shoes dry. In conclusion, flyknit uppers, with their unique advantages, are gradually becoming a new favorite in the footwear market, providing an ideal choice for consumers who pursue quality and comfort.

[0003] Existing multi-layer composite flyknit uppers involve applying adhesive between two layers during hot pressing, followed by repeated hot pressing of each layer, resulting in a multi-layered hot pressing process. Furthermore, wrinkles occasionally occur during lamination, leading to wrinkles in the final laminated upper. Utility Model Content

One end of one of the hot pressing rollers 9 is connected to the output shaft of the first servo motor 8 via a coupling, and the two hot pressing rollers 9 are connected by transmission.

[0031] Gears 10 are fixedly installed on both hot press rollers 9, and the two gears 10 are meshed together.

[0032] The anti-wrinkle mechanism includes a support block fixedly installed on the laminating table 5. A second servo motor 6 is fixedly installed on the support block. The output shaft of the second servo motor 6 is connected to the anti-wrinkle roller 7 through a coupling. The anti-wrinkle roller 7 is inclined.

[0033] It also includes a winding mechanism located on one side of the laminating table 5; the winding mechanism includes a first support frame 13, on which a winding drum 14 is rotatably connected via bearings, and one end of the winding drum 14 is drivenly connected to a third servo motor 16.

[0034] A drive synchronous pulley 15 is fixedly mounted on the output shaft of the third servo motor 16, and a driven synchronous pulley 22 is fixedly mounted on one end of the winding drum 14. The drive synchronous pulley 15 and the driven synchronous pulley 22 are connected by a synchronous belt drive.

[0035] The feeding mechanism includes a second support frame 12, and the feeding assembly includes a release cylinder 3 that is rotatably connected to the second support frame 12 via a bearing. One end of the release cylinder 3 is connected to the output shaft of the fourth servo motor 2 via a coupling.

[0036] The feeding mechanism also includes a third support frame 11, on which a guide roller assembly is connected. Each guide roller assembly includes two guide rollers 4 that are rotatably connected to the third support frame 11. The bottom of the third support frame 11 and the second support frame 12 are fixedly connected to the base plate 1.

[0037] In practical use, each fourth servo motor 2 drives each release cylinder 3 to rotate and release the corresponding fabric. Each fabric passes between the two guide rollers 4 in each guide roller group, and the two guide rollers 4 guide the released fabric. The second servo motor 6 drives the anti-wrinkle roller 7 to rotate, thereby flattening the released fabric and avoiding wrinkles. The first servo motor 8 drives the two hot press rollers 9 to rotate and hot press the fabric together.
