Description

Technical Field

[0001] The utility model relates to the field of spraying devices, in particular to a device for controlling the uniformity of plastic spraying. Background Technique

[0002] The device for controlling the uniformity of plastic spraying is a device specifically designed to ensure uniform coating distribution in plastic surface spraying operations. It mainly solves problems such as uneven coating thickness, inconsistent color, and uneven surface quality that may occur during plastic spraying. This device usually includes: a high-precision spray gun, a motion control system, a sensor monitoring system, and an intelligent control system.

[0003] Traditional spraying devices usually use linear motion or simple planar motion for spraying. This method can achieve good results when dealing with planar or regular-shaped workpieces. However, when facing semi-circular workpieces, since the movement trajectory of the spray gun cannot perfectly match the shape of the workpiece, it is easy to cause uneven coating distribution. At the top and bottom of the semi-circle, there are often situations of too thick or too thin coatings, seriously affecting the quality and performance of the product.

[0004] Therefore, a device for controlling the uniformity of plastic spraying is proposed. Content of the Utility Model

[0014] In a further technical solution, a plurality of equally spaced positioning ports are formed on the top surface of the workbench, at least six positioning bolts are inserted into the inner walls of the positioning ports, and a clamping plate is fixedly connected to the top surface of the positioning bolts.

[0015] Through the above technical solution, it is convenient to limit the bottom edge of the workpiece, and at the same time, the plugging operation is convenient.

[0016] In a further technical solution, a stopper is fixedly connected to one end of the sliding rod, and the surface of the stopper is attached to the rear surface of the guide plate.

[0017] Through the above technical solution, it is convenient to keep the sliding state of the sliding rod stable.

[0018] Compared with the prior art, the present utility model has the following beneficial effects:

[0019] By the rotation of the driving motor, one end of the support rod can rotate around the center of the mounting block, so that the spray head can spray the workpiece placed on the top surface of the workbench.

At the center of the bottom surface of the guide plate 3, a mounting block 4 is fixedly connected. On the surface of the mounting block 4, a motor 5 is fixedly connected. The output end of the motor 5 is fixedly connected with a support rod 6. The end of the support rod 6 far from the motor 5 is fixedly connected with an electric telescopic rod 10. The telescopic end of the electric telescopic rod 10 is fixedly connected with a connecting bolt 11. The connecting bolt 11 is fixedly connected with a spraying head 13 through an angle adjustment component. A connecting pipe 131 is communicated with the surface of the spraying head 13.

[0031] Please refer to Figure 1 and Figure 2 , The angle adjustment component includes a fixed block 12. The fixed block 12 is fixedly connected to the end of the connecting bolt 11 far from the electric telescopic rod 10. On one side of the fixed block 12 far from the connecting bolt 11, a rotating groove 14 penetrating to the inside is opened. The inner wall of the rotating groove 14 is rotatably connected with a rubber ball 15, and the opening diameter of the rotating groove 14 is smaller than the radius of the rubber ball 15. The end of the rubber ball 15 far from the fixed block 12 is fixedly connected with a connecting rod 16.

During the process, the spray head 13 can perform semi-circular spraying on the workpiece. In addition, during the spraying process, the electric telescopic rod 10 can be driven to adjust the lateral use position of the spray head 13 to improve the comprehensiveness of the sprayed workpiece. After each arc spraying is completed, the workpiece can be rotated to The unsprayed position faces the moving route of the spray head 13 for spraying. In addition, the positioning port 20 is set so that the excess paint in the spraying process can fall directly to avoid accumulation of paint on the surface of the workbench 1. When the workpiece needs to be sprayed horizontally, the motor 5 can be directly driven to let the spray head 13 face the spraying surface of the workpiece. In addition, when the spray head 13 needs to be used at an inclined angle, the rubber ball 15 can be rotated on the inner wall of the rotating groove 14 to adjust the outlet angle of the spray head 13, and then the anti-slip column 18 can be pressed against the current position of the rubber ball 15 by rotating the rotating head 19.
