Technical Field

[0001] The utility model relates to the technical field of end cap processing, in particular to a surface spraying device for end cap processing. Background Art

[0002] The end cap is a component used to seal the end of a container to isolate the internal and external media, also known as an end cap. The end cap is a component of a container, connected to the cylinder by welding. According to the shape of the end cap surface, it can be divided into convex, conical, flat and combined shapes. A convex end cap refers to a end cap with a convex outer surface, such as a hemispherical, elliptical, dished and spherical end cap without folded edges.

[0003] During the processing of existing hemispherical heads, due to their hemispherical shape, traditional spray guns are prone to dead spots during the spraying process, requiring secondary supplementary spraying, resulting in low overall spraying efficiency and affecting the processing flow; therefore, it does not meet existing needs. In this regard, we propose a surface spraying device for head processing. Utility Model Content

[0012] Preferably, a base is installed below the rotating table, a motor shaft is installed between the base and the rotating table, and the upper end of the motor shaft is assembled and installed with the rotating table.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model, through the arrangement of arc-shaped spraying rack, arc-shaped elbow, shunt pipe, control valve, nozzle, second electric telescopic rod, bracket and conveying pipe, enables the surface spraying equipment to effectively spray the hemispherical heads. During the spraying process, the nozzle positions are distributed in an arc shape, which can effectively spray the hemispherical arc surface, reduce the spraying dead angle, and facilitate the use of users;

[0015] Specifically, the second electric telescopic rod drives the bracket to move up and down, and the delivery pipe is a telescopic pipe, which is telescopic and retracts with the movement. At the same time, it is used to deliver the spray material in the storage tank into the arc-shaped curved pipe; the arc-shaped spraying rack and the arc-shaped curved pipe are both arc-shaped structures, and their volumes are larger than the volume of the head to be sprayed, so that the head can be covered inside for comprehensive spraying; the spray material in the arc-shaped curved pipe is diverted and transported from each diverter pipe to each nozzle for spraying operation, and the control valve is used to control the opening and closing state of each diverter pipe; after spraying, the arc-shaped spraying rack is driven upward by the second electric telescopic rod to retract, so that the rotating table below can rotate and replace the head;

[0016] The invention solves the problem that during the processing of the existing hemispherical head, due to the limitation of its hemispherical shape, the traditional spray gun is prone to have dead angles in the spraying process, and a secondary supplementary spraying is required, resulting in low overall spraying efficiency and affecting the processing flow.

[0017] 2. The driving motor is used to drive the transmission shaft and the driven platform to rotate, and the upper head body is driven to rotate by the rotation. In combination with the arc-shaped spraying assembly above, the head can perform a more comprehensive spraying operation by self-rotation, reducing the blind spots of spraying; when the first electric telescopic rod is extended, the limit block can be pressed against the inner wall of the head body. When multiple first electric telescopic rods are extended at the same time, the head body can be firmly fixed, thereby improving the firmness of the head when it is placed, and the position of the limit block can be adjusted by the first electric telescopic rod, which is convenient for adjusting heads of different sizes; after the spraying is completed, the limit block is no longer pressed against the head by retracting inward, so that the user can easily remove the head and replace it; the above structure can improve the spraying effect, and can improve the stability and firmness of the hemispherical head when it is placed. At the same time, it is convenient for users to quickly take out and replace it, thereby improving the overall processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
