the dispensing module (44) comprises a dispensing box (441), a filter cover (442), a dispensing shaft (443) and a dispensing motor (444), wherein the dispensing box (441) is a cuboid, a triangular groove is formed in the right lower corner of the cuboid, a cavity is formed in the cuboid, a feed inlet and an air outlet are formed in the upper surface of the dispensing box (441), the filter cover (442) is mounted at the air outlet, and a discharge outlet is formed in the bottom of the dispensing box (441); the material distributing shaft (443) is mounted on the inner wall of the spreading box (441), the material distributing shaft (443) is connected with an output shaft of the material distributing motor (444) fixed on the spreading box (441), the material distributing shaft (443) is positioned above a discharge hole of the spreading box (441), material passing holes are formed in the material distributing shaft (443) along the axial line, discharge holes are uniformly formed in the circumferential surface of the material distributing shaft (443) along the radial direction, and the discharge holes are communicated with the material passing holes;
when the paint pouring device works, after paint enters the tank body (1) through the feeding port of the tank body (1), the paint falls into the first funnel (21) and then flows out from the opening at the lower end of the first funnel (21); when the coating flows out of the lower end of the first hopper (21), the first mixing motor (23) drives the fan (22) to rotate, and the powdered coating is stirred for the first time under the blowing of the fan (22);
the coating continues to move downwards under the action of gravity and falls into the second hopper (31), the coating flows out of a discharge hole at the lower end of the second hopper (31) and then falls onto the rotating disc (32), the rotating disc (32) is driven by the second mixing motor (33) to rotate, the coating on the rotating disc (32) flies out around under the action of centrifugal force, the flown coating impacts the material baffle plate (34) and falls along the material baffle plate (34), and therefore the coating is mixed again;
the coating falls to the bottom of the tank body (1) after being mixed by the secondary mixing unit (3), and the coating is sent into the mixing cavity (41) after a discharge hole at the bottom of the tank body (1) is opened; before the coating enters the mixing cavity (41), the spreading box (441) is driven by the slide block (43) to enable a feed inlet on the spreading box (441) to be positioned right below the feed inlet of the mixing cavity (41), and the coating directly enters the spreading box (441) after falling into the mixing cavity (41); then, the air cylinder (42) drives the sliding block (43) to move horizontally, the dispensing box (441) moves horizontally at the same time, a discharge hole of the dispensing box (441) is opened, the dispensing motor (444) drives the dispensing shaft (443) to rotate in the moving process, the discharge holes in the dispensing shaft (443) intermittently discharge the coatings, the coatings are further dispersed, and the discharged coatings are mixed again to realize full stirring.
