The left and right sides of the outer wall of the rotating rod 7 are fixedly connected to the lower part of the corresponding screen plate 11. The finished paint product is poured into the screening box 1 along the feed hopper 2 and falls on the screen plate 11. Then the motor 3 is started to make the rotating rod 7 drive the eccentric wheels 8 on both sides to rotate, so that the end of the eccentric wheel 8 with a smaller outer diameter intermittently pushes up the screen plate 11, so that the screen plate 11 slides up and down in the screening frame 6 and squeezes the first spring 15. The elasticity of the first spring 15 can enhance the reciprocating effect on both sides of the screen plate 11, so that the screen plate 11 vibrates and screens the finished paint product, and the finished product material that falls out of the screen falls on the lower side of the inner cavity of the screening box 1 along the inclination of the push plate 10.

[0034] like Figure 2 , Figure 5As shown, an electric push rod 9 is installed on the inner wall of the lower side of the left end of the screening box 1, and a push plate 10 is fixedly connected to the driving end of the electric push rod 9. The front and rear ends of the push plate 10 are respectively slidably connected to the inner walls of the front and rear sides of the screening box 1.

The electric push rod 9 is started to push the material out of the discharge port 4. The staff can use the material box to continue. When the screen plate 11 needs to be cleaned, just pull the fixed block 17 upwards to make the bottom of the plug 18 disengage from the socket 16, so that the limit of the plug 18 on the plug block 12 is released, and then push the plug block 12 forward, and then pull the handle of the lifting plate 5 from the front to take the screening frame 6 out of the screening box 1, and then the screen plate 11 can be cleaned.

[0035] Working principle: First, pour the finished paint into the screening box 1 through the feed hopper 2 and drop it onto the screen plate 11. Then start the motor 3 to make the rotating rod 7 drive the eccentric wheels 8 on both sides to rotate, so that the end with the smaller outer diameter of the eccentric wheel 8 intermittently pushes up the screen plate 11, so that the screen plate 11 slides up and down in the screening frame 6 and squeezes the first spring 15. The elasticity of the first spring 15 can enhance the reciprocating effect on both sides of the screen plate 11, so that the screen plate 11 vibrates and screens the finished paint, and the finished product material that falls out of the screen is passed through the screen frame 6. The push plate 10 tilts and falls to the lower side of the inner cavity of the screening box 1, and then the electric push rod 9 is started to push the material out of the discharge port 4. The staff can use the material box to continue. When the screen plate 11 needs to be cleaned, just pull the fixing block 17 upwards to make the bottom of the plug 18 disengage from the socket 16, thereby releasing the limit of the plug 18 on the plug block 12, and then push the plug block 12 forward, and then pull the handle of the lifting plate 5 from the front to take the screening frame 6 out of the screening box 1, and then the screen plate 11 can be cleaned.
