The jacking screw mechanism 21 includes two groups of lead screws, which are distributed at both ends of the glue storage tray 2. A sliding column is arranged at the bottom of the glue storage tray 2, and the sliding column is slidably arranged on the rack 1. By driving the rotation of the nut sleeve, the lifting of the lead screw is realized, and then the lifting of the glue storage tray 2 is realized. An outlet is arranged on the glue storage tray 2, which can be connected to a recycling and filtering device to collect and filter the glue liquid and re-introduce it into the glue storage tray 2.

[0036] The coating roller group 3 is rotatably arranged on the rack 1, and the coating roller group 3 is arranged above the glue storage tray 2;

[0037] The coating driving mechanism 4 is arranged on one side of the rack 1 and is connected to the coating roller group 3; the coating driving mechanism 4 is used to drive the coating roller group 3 to rotate. The coating driving mechanism 4 includes a coating driving power source structure 41, a universal connecting shaft 42 and a friction wheel 43 structure. The power of the coating driving power source structure 41 is transmitted to the friction wheel 43 through the universal connecting shaft 42, and the coating roller group 3 realizes power transmission through the friction wheel 43.

[0038] The position adjusting mechanism 5 includes a cylinder 51, a wedge-shaped transmission block 52 and a wedge-shaped adjusting block 53. The wedge-shaped transmission block 52 is slidably arranged on the rack 1. One end of the cylinder 51 is fixed on the rack 1, and the other end is connected to the wedge-shaped transmission block 52 for driving the wedge-shaped transmission block 52 to slide. The wedge-shaped adjusting block 53 is slidably arranged on the rack 1 and is in wedge-shaped cooperation with the wedge-shaped transmission block 52. A fine-threaded lead screw 54 is installed on the wedge-shaped adjusting block 53, and the fine-threaded lead screw 54 is in threaded cooperation with the wedge-shaped adjusting block 53. The distance between the coating rollers can be adjusted through the position adjusting mechanism 5. In this embodiment, the coating roller group 3 includes a glue-coated roller 31, and the glue-coated roller 31 is used to stick glue in the glue storage tray 2 to provide glue liquid for the base fabric.

[0039] Embodiment 2

[0040] As Figure 6 shown, the coating roller group 3 includes a glue-coated roller 31 that can extend into the glue storage tray 2 and a transfer roller 32 arranged on one side of the glue-coated roller 31. Here is a two-roller working mode, adopting a single drive or a friction wheel drive method. The glue-coated roller 31 rotates to adhere the glue liquid in the glue storage tray 2. The position of the glue-coated roller 31 remains unchanged. The transfer roller 32 is moved near the glue-coated roller 31 through the position adjusting mechanism 5. The glue-coated roller 31 rotates counterclockwise, and the transfer roller is used for threading the cloth and rotates clockwise for coating. It is suitable for products with low requirements for glue coating uniformity and is easy to operate.

A glue scraping plate 34 is provided on one side of the glue roller 31. The position of the glue roller 31 remains unchanged. The transfer roller 32 and the adjusting roller 33 are moved near the glue roller 31 through the position adjusting mechanism 5. The glue roller 31 rotates clockwise to pick up the glue. When passing through the gap between the adjusting roller 33 and the glue roller 31, the excess glue is filtered out. The glue further rotates driven by the glue roller 31 and passes through the glue scraping plate to scrape the glue evenly. The transfer roller 32 is used for threading the cloth and rotates clockwise. When the glue moves to the gap between the glue roller 31 and the transfer roller 32, it is coated on the sandpaper, which is suitable for the glue coating scenario that requires accurate measurement.

The transfer roller 32 and the adjusting roller 33 are moved near the glue roller 31 through the position adjusting mechanism 5, and the back pressure roller 35 is moved near the transfer roller 32. The glue further rotates driven by the glue roller 31 and passes through the glue scraping plate to scrape the glue evenly. The transfer roller 32 rotates counterclockwise. When the glue rotates to the gap between the glue roller 31 and the transfer roller 32, the glue is pressed evenly again by the extrusion between the two rollers. The back pressure roller 35 is used for threading the cloth and rotates clockwise. When the glue moves to the gap between the back pressure roller 35 and the transfer roller 32, it is coated on the sandpaper, which is suitable for the scenario with extremely high requirements for glue coating uniformity.
