[0020] 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.

[0021] See Figures 1-4 As shown, it includes a base plate 1. The upper and lower ends of the base plate 1 are provided with a material wheel 2 and a material wheel 3. The material wheel 2 is located above the material wheel 3. The upper part of the base plate 1 is provided with two sets of adjustable limiting components. The two sets of adjustable limiting components are located in front of the material wheel 2 and the material wheel 3 respectively. The lower set of adjustable limiting components is provided with a scraping structure. In front of this set of adjustable limiting components, there is also a spraying component and a vibration structure. The upper and lower sides of the front end of the base plate 1 are respectively equipped with guide shafts 21. In front of the guide shafts 21, there are two pressing rollers 4 for pressing aramid and polyethylene materials. The base plate 1 is provided with a pressing motor 5 that is driven to the two pressing rollers 4.

[0022] The adjustable limiting assembly includes multiple horizontally mounted guide rail assemblies 6. Two sets of sliders 9 are slidably mounted on the guide rail assembly 6. A bidirectional screw 7 is also provided on the side of the guide rail assembly 6. The two sets of sliders 9 are symmetrically mounted on the bidirectional screw 7 via threads. An adjusting motor 8 is also provided on one side of the bracket on which the guide rail assembly 6 and the bidirectional screw 7 are mounted. The rotating shaft of the adjusting motor 8 is connected to the bidirectional screw 7. A "C"-shaped limiting block 10 is provided above each set of sliders 9.

[0023] By adjusting the motor 8, the bidirectional screw 7 can be rotated, which in turn can drive the sliders 9 on both sides and the limit blocks 10 to move towards each other or relative to each other along the guide rail assembly 6, thereby adjusting the distance between the limit blocks 10, which is suitable for use with fabrics of different widths.

[0024] See Figures 1-4 As shown, the glue scraping structure includes two inclined scrapers 11, both of which are connected to the front of the limiting block 10, and the inner end of the scraper 11 is flush with the vertical surface inside the limiting block 10. The base plate 1 is provided with a glue receiving tray 12, which is located directly below the two scrapers 11.

[0025] A scraper 11 is provided, which moves along with the limit block 10, so that the limit block 10 can limit the fabric while keeping the scraper 11 in contact with the edge of the fabric, thereby removing excess glue.

[0026] See Figures 1-4As shown, the glue spraying assembly includes a mounting base 14 installed above the front side of the limiting block 10. The mounting base 14 is located behind the scraper 11. Several nozzles 15 are provided below the mounting base 14. The nozzles 15 are connected to the glue supply equipment through the glue supply tube 13.

[0027] The vibration structure includes supports 16 mounted on both sides of the base plate 1, a movable plate 18 between the two supports 16, a flexible contact head 19 at the top of the movable plate 18, the flexible contact head 19 being located directly below the nozzle 15, a plurality of buffers 17 at the bottom of the movable plate 18, and a vibration motor 20 mounted on the movable plate 18.

[0028] Adhesive is supplied through the adhesive supply tube and sprayed from the nozzle 15 to achieve adhesive application. At the same time, the vibration motor 20 drives the movable plate 18 to generate low-frequency vibration, which causes the fabric surface to vibrate through the flexible contact head 19, so that the adhesive can flow evenly.

[0029] The usage process of this utility model:

[0030] After the equipment is started, the limit block 10 is adjusted according to the width of the fabric. The limit block 10 guides and limits the fabric to prevent it from deviating. The nozzle 15 sprays glue onto the material below. Vibration makes the glue even. Then the scraper 11 scrapes off the excess glue on both sides. The scraped glue flows into the glue receiving tray 12. Then the two layers of material are pressed together between the pressing rollers 4.

[0031] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof.
