[0002] Composite fabrics are fabrics made by bonding one or more layers of textile materials, non-woven materials and other functional materials together. Among them, nylon twill PU composite fabric, which combines nylon twill fabric with PU coating, not only has the characteristics of nylon twill fabric, but also adds functions such as waterproof, dustproof and antistatic properties.

[0003] Chinese patent CN215435486U discloses a bonding device for composite fabric processing. The key technical features include: a base plate with support columns mounted on both sides of its top; a first extrusion roller mounted between the bottom of the two support columns via bearings; a first crossbeam mounted on the top of the two support columns; a second extrusion roller mounted on the bottom of the first crossbeam via a lifting mechanism; and guide rollers mounted on the sidewalls of the two support columns via a first bracket. This invention quickly and effectively bonds two pieces of fabric together, improving production efficiency. An electric heating plate heats the extrusion plate, and the extension of a first electric telescopic rod pushes the extrusion plate downwards. The extrusion rod then extrudes and heats the two pieces of fabric, thereby eliminating wrinkles and improving the quality of the finished product.

[0004] Existing technologies often have the following drawbacks: When using a composite fabric bonding device to bond nylon fabric and PU, in order to ensure the tightness of the bond, it is necessary to control the glue to be sprayed evenly on the bonding surface. Therefore, when pressing and bonding nylon fabric and PU, glue is prone to overflow, making subsequent cleaning difficult.

[0005] Therefore, this utility model provides a device for precise bonding and pressing of nylon spun PU composite fabric. Utility Model Content

[0030] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a device for precise bonding and pressing of nylon twill PU composite fabric, including a base 1, two vertical plates 2 fixedly connected to the upper surface of the base 1, glue boxes 5 fixedly connected to the surfaces of the two vertical plates 2, horizontal plates 3 fixedly connected to the side of each of the two vertical plates 2 near the glue boxes 5, guide rollers 4 rotatably connected to the side of the two horizontal plates 3 close to each other, second extrusion rollers 7 rotatably connected to the side of the two vertical plates 2 close to each other, a first extrusion roller 6 installed on the side of the two vertical plates 2 close to each other, a cleaning device 8 provided on the side of the two vertical plates 2 close to each other, and a recycling device 9 provided on the upper surface of the base 1.

[0031] The specific setup and function of the cleaning device 8 and the recycling device 9 will be explained in detail below.

[0032] Reference Figures 1-4 As shown in this embodiment: the cleaning device 8 includes two base plates 81, which are fixedly connected to two vertical plates 2 respectively. Both base plates 81 are installed on the side of the vertical plates 2 closest to the first extrusion roller 6. Slide plates 86 are slidably connected to the inner walls of both base plates 81. A top plate 83 is fixedly connected to the side of the slide plate 86 away from the base 1. Scrapers 85 are fixedly connected to the sides of the two base plates 81 and the top plate 83 that are close to each other. During the bonding process of nylon fabric and PU using the first extrusion roller 6 and the second extrusion roller 7, the slide plate 86 can be used in conjunction with the scraper 85 to clean up any overflowing adhesive. A collection box 88 is fixedly connected to the upper surface of the base 1, and two collection slots 87 are fixedly connected to the upper surface of the collection box 88. The collection slots 87 guide the cleaned-up adhesive into the collection box 88, completing the collection of the adhesive.

[0033] Both vertical plates 2 have grooves on their adjacent sides, and sliders 82 are slidably connected to the surfaces of the grooves on both vertical plates 2. The sliders 82 are fixedly connected to the top plate 83, and two guide ramps 89 are fixedly connected to the inner wall of the collection box 88. The sliders 82 ensure a stable connection between the top plate 83 and the vertical plates 2, while also allowing the top plate 83 to move. The guide ramps 89 guide and adjust the position of the glue within the collection box 88. An adjusting screw 84 is threaded into the inner wall of the top plate 83 and is rotatably connected to the bottom plate 81. The adjusting screw 84, rotatably connected to the bottom plate 81, can be rotated to adjust the position of the top plate 83.

[0034] Reference Figure 1 and Figure 5 As shown, specifically, the recycling device 9 includes an extraction pipe 92 installed inside the collection box 88. A pump body 93 is fixedly connected to the upper surface of the base 1. The input end of the pump body 93 is fixedly connected to the extraction pipe 92, and the output end of the pump body 93 is fixedly connected to a circulation pipe 94, which is connected to the glue tank 5. Through the extraction pipe 92, pump body 93, and circulation pipe 94, the collected glue can be transported back to the glue tank 5, thus completing the recycling of the glue.

[0035] A heating plate 91 is fixedly connected to the inner wall of the collection box 88, and a scraper ring 95 is slidably connected to the surface of the extraction tube 92. The heating plate 91 maintains the temperature inside the collection box 88, thus slowing down the curing speed of the adhesive. The scraper ring 95 cleans the adhesive adhering to the surface of the extraction tube 92. A fixing plate 96 is fixedly connected to the upper surface of the collection box 88, and an electric telescopic rod 97 is fixedly connected to the inner wall of the fixing plate 96. The output end of the electric telescopic rod 97 is fixedly connected to the scraper ring 95. The fixing plate 96 allows the electric telescopic rod 97 to be connected to the collection box 88, and activating the electric telescopic rod 97 controls the movement of the scraper ring 95.

[0036] The working principle is as follows: when bonding nylon fabric and PU, the nylon fabric is first passed through the guide roller 4 on the horizontal plate 3, and then the nylon fabric and PU are passed through the first extrusion roller 6 and the second extrusion roller 7 on the vertical plate 2. The glue in the glue box 5 is evenly sprayed onto the nylon fabric by the glue gun installed on the side of the glue box 5 near the base 1. The two are then bonded by the extrusion of the first extrusion roller 6 and the second extrusion roller 7. When bonding nylon fabric and PU, the adjusting screw 84 is rotated to rotate on the inner wall of the top plate 83 and the surface of the bottom plate 81. Under the constraint of the slider 82, the distance between the top plate 83 and the bottom plate 81 is adjusted. During the process of the first extrusion roller 6 and the second extrusion roller 7 extruding and bonding the nylon fabric and PU, the scraper 85 and the slide plate 86 scrape off the overflowing glue. The overflowing glue enters the collection box 88 through the collection groove plate 87. Then, the guide plate 89 guides the glue to flow in the collection box 88 and adjusts the position of the glue in the collection box 88. Through the cleaning device 8, the overflowing glue can be cleaned and collected during the bonding process of nylon fabric and PU, thereby avoiding the situation where the overflowing glue drips onto the base 1 as much as possible and reducing the difficulty of subsequent glue cleaning.

[0037] During the bonding process of nylon fabric and PU using the composite fabric precision bonding and pressing device, the heating plate 91 is activated to heat the adhesive in the collection box 88 to prevent it from solidifying. At the same time, the pump body 93 is activated to draw the adhesive in the collection box 88 into the glue tank 5 through the extraction pipe 92 and the circulation pipe 94, completing the adhesive recovery. While recovering the adhesive, the electric telescopic rod 97 on the fixed plate 96 is activated to control the scraper ring 95 to separate the adhesive on the surface of the extraction pipe 92, preventing the adhesive from solidifying on the surface of the extraction pipe 92. Through the set recovery device 9, the collected adhesive can be transported back to the glue tank 5 during the bonding process of nylon fabric and PU using the composite fabric precision bonding and pressing device, improving the utilization rate and processing efficiency of the adhesive.
