the discharging element 34 is controlled by the central control, so that the coating of the storage unit 30 is sent to the spraying element 41, and the spraying element 41 sprays the coating to the hammer head;

excess coating flows from the spray tank member 11 into the recovery tank member 61;

the fourth driving element 64 is controlled by the central control to drive the second stirring element 63 to stir the coating of the recovery box element 61, so that precipitation and unevenness are avoided;

the fluid conveying element 62 is controlled by the central control so that the coating of the recovery tank element 61 is conveyed to the storage tank element 31 after being filtered by the first filter element 71 and/or the second filter element 72;

after spraying for a certain time, the feeding of the coating material of the storage unit 30 to the spraying element 41 is stopped by the central control discharging element 34;

the gas conveying element 51 and the heating element 52 are controlled through central control to supply drying gas to the hammer head;

after drying for a certain time, the gas conveying element 51 and the heating element 52 are controlled by the central control to stop supplying the drying gas to the hammer head;

opening the spray door member 12, holding the retainer plate member 25 with a hand and rotating the turning member 23 in a counterclockwise direction to move the gripper plate member 24 away from the hammer head;

and taking out the hammer head and carrying out spraying work on the next hammer head.

The utility model has the advantages that the worktable unit can clamp and rotate the hammer head, thereby solving the problem of uneven spraying of the hammer head and improving the product yield; the spraying unit sprays the hammer head uniformly from multiple angles, so that the coating is uniformly distributed on the surface of the hammer head; after the coating is sprayed, the drying unit quickly dries the hammer head immediately, so that the problems of long drying time, low drying efficiency, uneven coating, micro bubbles of a product and the like in the process of transferring the hammer head are solved; and the recovery unit and the filtering unit are used for filtering and recovering redundant coatings, so that the times of supplementing new coatings are reduced, the production cost is reduced, and the utilization rate of the coatings is improved.

The above description is only an example of the preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and those skilled in the art should be able to realize the equivalent alternatives and obvious variations of the present invention.
