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.

[0025] Please see Figure 1-6 This utility model provides a technical solution:

[0026] A sandpaper gluing device for easy recycling of excess glue includes a workbench 1, a gluing mechanism 2 on the top of the workbench 1, and a recycling mechanism 3 on the top of the workbench 1. The recycling mechanism 3 includes:

[0027] The recycling component 31 includes a support rod 311 that is slidably installed inside the workbench 1. A recycling plate 312 is fixedly connected to the top of the support rod 311.

A filter plate 315 is installed inside the recycling pipe 314. A collection box 317 is fixedly connected to the bottom of the recycling pipe 314 through a folded pipe 316.

[0028] Adjustment component 32 is located on the top of workbench 1 and is used to adjust the height of the glue-spreading plate 313.

[0029] The support rod 311 serves to support the recycling plate 312, providing a stable support structure for the recycling plate 312;

[0030] The recycling plate 312 is used to receive the glue flowing from the glue spreading plate 313 and guide the glue to the recycling pipe 314;

[0031] The filter plate 315 is bolted inside the recovery pipe 314 and is made of filter screen or porous material to intercept glue impurities and ensure the purity of the recovered glue.

[0032] Collection bin 317 is used to store recycled glue for easy subsequent processing or reuse.

[0033] In this embodiment, the adjustment assembly 32 includes an adjustment cylinder 321 and an adjustment plate 322 installed on the top of the workbench 1. The output end of the adjustment cylinder 321 is fixedly connected to a sliding plate 323. The surface of the sliding plate 323 is slidably connected to the interior of the adjustment plate 322. The top end of the sliding plate 323 is fixedly connected to a sliding block 324.

[0034] The regulating cylinder 321 is connected to an external air source via an air pipe;

[0035] The top of the adjusting plate 322 is provided with a sliding groove to provide a sliding track and support for the sliding plate 323, ensuring that the sliding plate 323 slides stably.

[0036] In this embodiment, a connecting plate 4 is fixedly connected to the bottom of the recycling plate 312, and an inclined groove 5 is provided on the surface of the connecting plate 4. The inner surface of the inclined groove 5 is slidably connected to the surface of the sliding block 324.

[0037] The inclined slide 3122 has a designed inclination angle, which works in conjunction with the sliding block 324 to achieve the lifting function.

[0038] Through the ingenious design of the recycling mechanism 3, excess glue can be quickly collected by the glue-spreading plate 313, and then flow into the collection box 317 through the recycling plate 312 and the recycling pipe 314. The filter plate 315 effectively ensures the purity of the recycled glue, and the folded pipe 316 facilitates the installation and disassembly of the collection box 317. The entire recycling process is efficient and convenient, greatly reducing glue waste, lowering production costs, and maintaining a clean working environment.

[0039] In this embodiment, the gluing mechanism 2 includes a glue box 21 and a support plate 22 installed on the top of the workbench 1. A rotary motor 23 is fixedly connected to the outside of the support plate 22. One end of the output shaft of the rotary motor 23 is fixedly connected to the gluing roller 24 through a coupling. A lifting block 25 is slidably connected inside the support plate 22. A pressure roller 26 is rotatably connected to the inside of the lifting block 25. A lifting screw 27 is threadedly connected inside the lifting block 25. The surface of the lifting screw 27 is rotatably connected to the inside of the support plate 22. A rotating handle 28 is fixedly connected to the top of the lifting screw 27. A glue scraping assembly 29 is provided on the surface of the glue box 21.

[0040] The rotating motor 23 is a three-phase asynchronous motor and is connected to an external circuit via wires;

[0041] Glue box 21 is used to store glue and provide a source of glue for the glue application process;

[0042] The operator can adjust the height of the pressure roller 26 by turning the handle 28, which in turn drives the lifting screw 27 to rotate.

[0043] In this embodiment, the glue scraping assembly 29 includes a control box 291 mounted on the surface of the glue box 21. A control screw 292 is rotatably connected inside the control box 291. A folded rod 293 is threadedly connected to the surface of the control screw 292. The surface of the folded rod 293 is slidably connected to the inside of the control box 291. A glue scraper 294 is fixedly connected to one end of the folded rod 293.

[0044] The scraper blade 284 is made of wear-resistant material and has a certain degree of elasticity. One side is closely attached to the surface of the glue roller 24 and is used to scrape off excess glue from the surface of the glue roller 24.

[0045] In this embodiment, the scraper 294 is disposed above the glue box 21, and one side of the scraper 294 is in contact with the surface of the glue roller 24.

[0046] With the glue application mechanism 2, the glue thickness on the surface of the glue application roller 24 can be precisely controlled by the glue scraping component 29, ensuring that the sandpaper is glued evenly. The distance between the pressure roller 26 and the glue application roller 24 can be flexibly adjusted by the lifting screw 27. The height of the glue spreading plate 313 of the recycling mechanism 3 can be adjusted by the adjustment component 32, so that the equipment can adapt to the production needs of sandpaper of different thicknesses, significantly improving the versatility and production flexibility of the equipment and improving the quality of sandpaper products.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0048] When using this device, first, according to the thickness of the sandpaper, rotate the lifting screw 27 to adjust the distance between the pressure roller 26 and the glue roller 24; at the same time, start the adjusting cylinder 321 and adjust the glue spreading plate 313 to a suitable height through the adjusting component 32.

[0049] Subsequently, the rotating motor 23 is started to drive the glue-applying roller 24 to rotate. The glue in the glue box 21 is applied to the surface of the glue-applying roller 24. The control screw 292 is rotated to adjust the position of the folding rod 293, which drives the scraper 294 to move. The adhesion between the scraper 294 and the glue-applying roller 24 is adjusted. The scraper 294 scrapes off the excess glue on the surface of the glue-applying roller 24. The rotation of the glue-applying roller 24 drives the sandpaper to move. Under the action of the pressure roller 26, the glue-applying process is completed. Continuing to be conveyed by the subsequent conveying device, the glue-spreading plate 313 will spread the glue under the sandpaper evenly. The excess glue falls on the glue-spreading plate 313 and flows into the collection box 317 through the recycling plate 312, recycling pipe 314 and folding pipe 316. The filter plate 315 filters the recycled glue.

[0050] During the production process, the position of the scraper 294, the spacing of the pressure rollers 26, and the height of the glue-spreading plate 313 can be adjusted at any time according to actual production needs to ensure the glue application quality and glue recycling effect, and achieve efficient and precise sandpaper glue application production.
