[0014] The present invention provides a new type of crushing and filtering device for paint production. It has the following beneficial effects:

[0015] (1) In order to facilitate the crushing operation, the new type of paint production crushing and filtering device can, when the rotating rod rotates, drive the cylindrical block to move in the middle of the moving frame, so that the two sets of shielding plates can move back and forth through the L-shaped connecting rod, open and close the feed cover, and perform intermittent feeding, which is convenient for the crushing operation and prevents excessive addition of raw materials into the feed cover, causing the feed cover to be blocked. When the moving frame moves, the top of the moving frame will squeeze the arc block, and through the cooperation of the reset spring, the transmission plate can move up and down. Through the cooperation of the hinged rod, the transmission rod can drive the striking rod to move left and right in the feed cover, which is convenient for breaking up the paint raw materials that are stuck together and performing the crushing operation of the crushing roller.

[0016] (2) The new type of crushing and filtering device for paint production can drive the L-shaped connecting rod to move back and forth when the movable frame moves back and forth, so that the long plate can drive the breaking rod to move back and forth on the filter plate, and the raw materials that fall to one position after being crushed can be dispersed, which is convenient for the filter plate to perform screening operations. When the long plate moves back and forth, the inclined block moves back and forth on the triangular block, and through the cooperation of the movable rod, the auxiliary rod, the connecting seat and the knocking ball, the knocking ball can knock the filter plate back and forth, thereby improving the screening efficiency and preventing the filter plate from being blocked.

[0017] (3) In the new type of crushing and filtering device for paint production, when the long plate moves back and forth, when the raw materials accumulated on the filter plate are too much and higher than the push plate, when the push plate moves, the push plate will be subjected to extrusion force. Through the cooperation of the connecting column and the inclined rod, the push rod will squeeze the transmission block, so that the transmission block can drive the limit rod to move out of the limit hole, thereby releasing the limit on the filter plate. Because the spring sheet is in a stretched state, the spring sheet drives the filter plate to rotate downward, causing the filter plate to tilt, and the raw materials on the filter plate are discharged from the opening on the right side of the filter box, preventing excessive accumulation of raw materials in the equipment from causing blockage and damage to the machine body.
