Description

Technical Field

[0001] This utility model relates to the field of sandpaper production technology, and in particular to a coating system for a high-efficiency, environmentally friendly, water-based green sandpaper production line. Background Technology

[0002] The role of the coating system in the production of high-efficiency, environmentally friendly water-based green sandpaper is mainly reflected in improving production efficiency, ensuring product quality, and promoting environmentally friendly production. The specific functions are as follows: 1) In the production process of high-efficiency, environmentally friendly water-based green sandpaper, the coating system can automatically or semi-automatically complete the coating treatment of the sandpaper surface. Compared with traditional manual spraying, the coating system can significantly reduce the time required for spraying and improve production efficiency. At the same time, the tooling design ensures a more uniform coating, reducing problems such as uneven coating and missed coating caused by improper manual operation, thereby further improving production efficiency and product quality. 2) The coating system can ensure that key indicators such as coating thickness, uniformity, and adhesion on the sandpaper surface meet production requirements. The tooling design usually considers factors such as the characteristics of the coating, the properties of the sandpaper substrate, and the production environment, thereby ensuring stable and reliable coating quality. In addition, the tooling can reduce coating waste, lower production costs, and reduce the scrap rate of sandpaper due to coating quality problems, improving overall product quality.

[0003] Existing adhesive coating systems for sandpaper production have several shortcomings. First, when the viscosity of the water-based coating liquid is high, clogging can easily occur, resulting in uneven application and affecting subsequent sanding operations. Second, they cannot quickly heat the base paper after spraying, which hinders the rapid curing of the water-based coating liquid. Therefore, optimization and improvement are necessary. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a coating system for an efficient and environmentally friendly water-based green sandpaper production line.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A coating system for an efficient and environmentally friendly water-based green sandpaper production line includes a uniform drying component, a coating component, and a spreading component. The uniform drying component is located below the base paper conveying surface, and the coating component and the spreading component are sequentially located above the base paper conveying surface.

[0007] The adhesive application assembly includes a conveying auger, a hopper, a distribution pipe, an anti-clogging cam, and a drive shaft. The upper side of one end of the conveying auger is provided with a feed inlet, and a hopper is installed at the feed inlet. The lower side of the other end of the conveying auger is provided with a discharge outlet, and multiple distribution pipes are installed side by side at the discharge outlet. Each distribution pipe consists of an anti-clogging expansion section and an inlet pipe and an outlet pipe connected to its upper and lower ends. An anti-clogging cam is installed inside the anti-clogging expansion section of each distribution pipe. All the anti-clogging cams are driven to rotate by a drive shaft that passes through the distribution pipe.

[0008] The smoothing assembly includes a base frame and multiple smoothing units mounted side by side thereon, wherein the distance between the smoothing roller and the base paper conveying surface in each smoothing unit gradually decreases along the base paper conveying direction.

[0009] Furthermore, in the coating system of the above-mentioned high-efficiency and environmentally friendly water-based green sandpaper production line, the uniform drying component includes a circulating heat conduction tape, a drive wheel, a driven wheel, a heat insulation frame, and heating lamps. The circulating heat conduction tape is sleeved on the outside of the drive wheel and the driven wheel. A heat insulation frame is installed inside the circulating heat conduction tape. The upper end of the heat insulation frame is open. Several heating lamps are installed side by side inside the heat insulation frame.

[0010] Furthermore, in the adhesive coating system of the aforementioned high-efficiency and environmentally friendly water-based green sandpaper production line, the upper layer of the circulating heat-conducting tape abuts against the lower side of the base paper and the upper side of the heat insulation frame on the base paper conveying surface, respectively.

[0011] Furthermore, in the glue coating system of the above-mentioned high-efficiency and environmentally friendly water-based green sandpaper production line, one end of the drive shaft is connected to the output shaft of the drive motor via a coupling, and the drive motor is fixed to the outer shell of the conveying auger via a motor bracket.

[0012] Furthermore, in the adhesive coating system of the aforementioned high-efficiency and environmentally friendly water-based green sandpaper production line, the smoothing unit includes a mounting base with a vertical groove. A movable block is slidably restricted in the vertical groove.

A flip motor is installed on the support plate, and the output shaft of the flip motor is connected to the central shaft of the smoothing roller through a belt drive component.

[0013] Furthermore, in the coating system of the above-mentioned high-efficiency and environmentally friendly water-based green sandpaper production line, the outer surface of the spreading roller is provided with a Teflon coating that is not easily adhered to by grease.

[0014] The beneficial effects of this utility model are:

[0015] The adhesive coating system provided by this utility model is reasonably designed and mainly consists of a uniform drying component, an adhesive coating component, and a spreading component. The uniform drying component is located below the base paper conveying surface, while the adhesive coating component and the spreading component are sequentially located above the base paper conveying surface. The components work together to continuously and uniformly heat the bottom side of the base paper in the base paper conveying surface, which is conducive to the rapid curing of the water-based coating liquid. The adhesive coating component can apply the water-based coating liquid with high viscosity to the base paper at intervals, which is less likely to cause clogging. The spreading component can distribute and spread the water-based coating liquid on the base paper evenly, which is beneficial to the subsequent sand planting operation.
