The rotation of the L-shaped rod will drive the wheel to rotate, and the rotation of the wheel will contact with the ground to generate friction. Under the action of the friction, the wheel is driven to rotate, and the rotation of the wheel drives the stirring plate to rotate, thereby improving the mixing effect between the pigments and preventing uneven dispersion of the pigments during stirring, resulting in inconsistent gloss effect of the pigments in the final product.

The circular scraper will drive the connecting shaft to move up and down during the up and down movement, and the up and down movement of the connecting shaft will drive the pulley to move up and down. The pulley will contact the inner wall of the feeding box during the up and down movement, and the pigment attached to the surface will be shaken off by the vibration of the circular scraper, thereby improving the utilization efficiency of the pigment, and the trapezoidal block is reset by the No. 2 spring.

[0011] According to the above technical solution, the unloading device includes a connecting port, a discharging port, a control valve and an electric skateboard. After the stirring is completed, the electric skateboard is opened to allow the stirred pigment to enter the discharging port.

[0013] The present invention provides a pearlescent pigment feeding device that prevents dust from overflowing. It has the following beneficial effects: This invention pushes the semicircular plate to rotate and put the pigment into the feeding box. After the pigment is put into the feeding box, the semicircular plate will be reset under the drive of the No. 1 torsion spring to prevent pigment dust from floating out during the feeding process, causing some pigment to leak. At the same time, when the semicircular plate rotates downward, it will drive the rotating plate to rotate upward. At the same time, the rotating plate rotates upward to close the feeding box outlet, preventing the pigment from falling from too high a position and splashing a lot of dust, which may easily cause dust overflow. At the same time, the overflowed dust may be inhaled into the lungs of workers, endangering personal safety.

[0014] This invention uses a motor to drive the stirring rod to rotate, thereby stirring the pearlescent pigment and improving the mixing effect of the pigment. During the stirring, the wheel contacts the feeding box, and the friction between the wheel and the feeding box drives the wheel to rotate. The rotation of the wheel drives the stirring plate to rotate. Through stirring, the mixing effect between the pigments is improved, and uneven dispersion of the pigment during the stirring process is prevented, resulting in inconsistent gloss effect of the pigment in the final product.

[0015] This invention drives the reciprocating screw to rotate through electric rotation, and the rotation of the reciprocating screw drives the circular scraper to move up and down. The up and down movement scrapes off the paint adhering to the inner wall of the feeding box to prevent the paint from adhering to the inner wall surface and being unable to be utilized. The circular scraper drives the pulley to rotate while moving up and down, and the rotation of the pulley hits the circular scraper, shaking off the paint remaining on the surface of the circular scraper, thereby improving the utilization efficiency of the paint.

[0016] This invention uses an electric slide to open, allowing the paint to enter the discharge port. The paint is then discharged through a controlled valve to color the product. Simultaneously, the electric slide moves the triangular block to contact the protrusion, generating vibrations that shake the paint out of the feeding box, preventing the paint from clinging tightly together and getting stuck at the connection port, preventing it from entering the discharge port and affecting work efficiency.
