[0028] See also Figure 1-Figure 5 The utility model provides a technical solution: a paint grinder with a screening structure, comprising a collecting box 1, a grinding box 2 and a feed bin 3. The feed bin 3 is arranged on the upper surface of the grinding box 2. The feed bin 3 serves as the entrance of the paint. The design of the feed bin 3 can ensure that the paint can enter the grinding box 2 smoothly and evenly. The internal stirring mechanism pre-mixes the paint before it enters the grinding box 2, which helps to evenly mix the paint and improve the grinding effect. Through holes are provided at the bottom of the feed bin 3, the upper surface of the grinding box 2 and the upper surface of the collecting box 1. The grinding box 2 is arranged above the feed bin 3. The grinding box 2 is the main place for grinding the paint. The roller group 204 installed inside can efficiently grind the paint to achieve the required fineness and uniformity. At the same time, the filter screen plate 206 below the grinding box 2 can screen the ground paint, remove impurities and unqualified particles, and ensure the quality of the paint. A scraping mechanism is provided inside the collecting box 1;

[0029] The scraping mechanism includes a scraping unit and a cleaning unit;

[0030] The scraping unit includes a chute 102, a cylinder 103, a slider 104 and a scraper 105. The chute 102 is opened on the front and rear sides of the left wall inside the collection box 1. The slider 104 is slidably connected to the inside of the chute 102. The bottom of the slider 104 is fixedly connected to the output end of the cylinder 103. The right-angle surface of the scraper 105 is fixedly connected to the right side of the slider 104. There are two groups of scraping units, which are respectively arranged on both sides of the inner wall of the collection box 1. The scraping unit drives the slider 104 and the scraper 105 to move through the cylinder 103.

[0031] The cleaning unit includes an electric push rod 108, a cleaning push plate 106 and a cleaning inclined block 107. The bottom of the electric push rod 108 is fixedly connected between the outer wall and the inner wall of the front of the collection box 1. The output end of the electric push rod 108 is fixedly connected to the front of the cleaning push plate 106. The right-angle surface of the cleaning inclined block 107 is fixedly connected to the back of the cleaning push plate 106. A discharge port 101 is provided on the back of the collection box 1. Universal wheels 5 are fixedly connected around the lower surface of the collection box 1. The cleaning unit uses the electric push rod 108 to push the cleaning push plate 106 and the cleaning inclined block 107 to push the residual paint out of the collection box 1. This mechanism greatly improves the cleanliness and maintenance efficiency of the equipment. Universal wheels 5 are fixedly connected around the lower surface of the collection box 1 and are installed on the lower surface of the collection box 1, so that the equipment can be easily moved and positioned. This greatly improves the flexibility and applicability of the equipment, and is convenient for operation or transportation in different locations.

[0032] A stirring mechanism is arranged inside the feeding bin 3, and the stirring mechanism includes a cross block 6, a driving motor 301, a rotating shaft 302 and a stirring rod 303. The cross block 6 is fixedly connected to the bottom of the feeding bin 3, and the bottom of the rotating shaft 302 is rotatably connected to the middle of the upper surface of the cross block 6. The stirring rod 303 is fixedly connected to the rotating shaft 302. There are two groups of stirring rods 303, each group has two stirring rods, which are respectively arranged at the upper and lower positions of the rotating shaft 302. The arrangement of multiple stirring rods 303 can ensure that the paint is fully mixed, thereby improving the uniformity of the paint and the grinding effect.

[0033] A roller group 204 is arranged above the inside of the grinding box 2. The roller group 204 is the core component in the grinding box. The roller group 204 grinds the paint by rotation and friction. The drive of the motor group 202 enables the roller group 204 to work stably and continuously, ensuring the grinding effect and output of the paint. The right end of the transmission shaft in the roller group 204 is fixedly connected to the motor group 202, and the bottom of the motor group 202 is fixedly connected to the support plate 201. A placement plate 205 is arranged below the grinding box 2, and a filter screen plate 206 is movably connected to the inside of the placement plate 205. A handle 203 is fixedly connected to the front of the filter screen plate 206, so that the filter screen plate 206 can be easily replaced and cleaned.

[0034] Working principle: Move the device to a suitable position through the handle 204 and the universal wheel 5. When the paint enters through the entrance of the feed bin 3, the drive motor 301 starts, driving the rotating shaft 302 and the stirring rod 303 fixed thereon to rotate. Multiple groups of stirring rods 303 fully mix and stir the paint during the rotation process to ensure that the paint reaches a certain uniformity before entering the grinding box 2. The pre-stirred paint enters the grinding box 2 through the through hole. The motor group 202 drives the roller group 204 to rotate, and the paint is efficiently ground through the friction and extrusion between the roller and the paint to achieve the required fineness and uniformity. The ground paint enters the collection box 1 through the through hole. In this process, the filter screen 206 screens the paint to remove impurities and unqualified particles. When a certain amount of paint is collected in the collection box 1, the scraping mechanism and cleaning unit start working by operating the cylinder 103 and the electric push rod 108. The scraping unit drives the slider 104 and the scraper 105 to move along the slide 102 through the cylinder 103 to scrape the paint residue on the inner wall of the collection box 1. The cleaning unit pushes the cleaning push plate 106 and the cleaning inclined block 107 through the electric push rod 108 to push the scraped paint out of the discharge port 101 of the collection box 1.
