[0022] See also Figure 1-3, One embodiment of the present utility model is: a grinding device for paint processing with a screening function, comprising a box body 1, a box door 2 is provided on the front of the box body 1, a feed hopper 3 is provided on the top of the box body 1, a box body is slidably connected to the interior of the box body 1, and the ground paint can be collected, and a grinding mechanism 4 is provided inside the box body 1, and the grinding mechanism 4 includes a frame body 41, a motor 43, a rotating rod 44, a blade 45, a screen 46 and a grinding roller 48. The frame body 41 is fixedly installed inside the box body 1, and the motor 43 is fixedly installed on the left side of the inner wall of the box body 1. The output end of the motor 43 is rotatably connected to the left end of the rotating rod 44 through a connecting rod, the blade 45 is fixedly installed on the outer wall of the rotating rod 44 and is located inside the frame body 41, the screen 46 is arranged inside the frame body 41, and the grinding roller 48 is arranged below the screen 46. The front of the frame body 41 is hinged with a cover plate 42, and the right end of the rotating rod 44 is connected to the right side of the inner wall of the frame body 41 through a bearing. Rotationally connected, the rotating rod 44 passes through the left side of the frame 41 and is rotatably connected to the frame 41, and the grinding roller 48 is rotatably connected to the inside of the frame 41. The frame 41 can be opened by setting a cover 42, and the cover 42 can be closed and installed on the frame 41. Two relatively arranged grinding blocks 47 are fixedly installed inside the frame 41, and the grinding roller 48 is located between the two grinding blocks 47. The left end of the grinding roller 48 is fixedly installed with a round rod 412, and the round rod 412 passes through the left side of the frame 41 and is rotatably connected to the frame 41. An arc groove is provided on the grinding roller 47, and the two opposite arc grooves form a semicircular groove, so that the grinding roller 48 can rotate in the semicircular groove. The outer wall of the coupling rod is fixedly sleeved with a transmission wheel 1 49, and the left end of the round rod 412 is fixedly mounted with a transmission wheel 2 411. The outer wall sleeves of the transmission wheel 1 49 and the transmission wheel 2 411 are provided with a conveyor belt 410, and the conveyor belt 410 is movably connected to the transmission wheel 1 49 and the transmission wheel 2 411.

[0023] Working principle: By pouring the paint from the feed hopper 3 into the interior of the box 1, the paint will enter the interior of the frame 41, and the screen 46 will screen the paint. The large particles in the paint will remain on the top of the screen 46, and the small particles will fall down. The starting motor 43 will drive the connecting rod to rotate, and the connecting rod will drive the rotating rod 44 to rotate. The rotating rod 44 will drive the blade 45 to rotate. The blade 45 will crush the large particles of paint remaining on the top of the screen 46 so that the large particles of paint can pass through the screen 46. When the connecting rod rotates, it will drive the transmission wheel 1 49 to rotate. The transmission wheel 1 49 drives the transmission wheel 2 411 to rotate through the conveyor belt 410. The transmission wheel 2 411 drives the round rod 412 to rotate. The round rod 412 drives the grinding roller 48 to rotate, thereby grinding the fallen paint. The ground paint will fall into the box body inside the box 1. Rotating the cover 42 can open the frame 41, making it convenient for the staff to clean the inside of the frame 41.

[0024] See also Figure 3On the basis of the above embodiment, in another embodiment of the present utility model, the screen 46 is slidably connected to the inside of the frame 41, and a U-shaped rod 6 is slidably connected to the screen 46. The outer wall fixed sleeve of the U-shaped rod 6 is provided with a disc 7, and the outer wall sleeve of the U-shaped rod 6 is provided with a spring 8. By setting the U-shaped rod 6, the screen 46 can vibrate stably, and the two ends of the spring 8 are respectively fixedly connected to the top of the disc 7 and the top of the screen 46. The outer wall of the rotating rod 44 is fixedly installed with an extrusion rod 5. The top arc-shaped extrusion rod 5 is set, and the number of the extrusion rods 5 is two. The top arc-shaped setting can better extrude the screen 46. The number of U-shaped rods 6, springs 8 and discs 7 is four, which are arranged in four groups at the four corners of the screen 46. The screen 46 can be driven to reset by setting the spring 8.

[0025] Working principle: When the paint is screened, the rotation of the rotating rod 44 will drive the extrusion rod 5 to rotate, and the arc surface on the top of the extrusion rod 5 will squeeze the screen 46, and the screen 46 will move down a certain distance. When the extrusion rod 5 does not squeeze the screen 46, the screen 46 will reset and move up under the action of the spring 8, thereby repeatedly causing the screen 46 to vibrate, thereby improving the screening efficiency.

[0026] It is worth noting that the motor 43 is controlled by a controller, the blade 45 can crush the material, and the grinding roller 48 can grind the coating. The above are all existing technologies and are not the main innovations, so they will not be described in detail here.

[0027] The present invention provides a grinding device for coating processing with a screening function. There are many methods and approaches for implementing this technical solution. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Any components not specified in this embodiment may be implemented using existing technologies.
