Description

Technical Field

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

[0002] Plastic products are a general term for daily necessities, industrial products, etc. processed mainly with plastics as raw materials. During the production and processing of plastic products, a spraying process can be carried out. The functions of spraying plastic products mainly include increasing wear resistance, corrosion resistance, acting as seals for hydraulic components, airtightness, sound absorption, insulation, heat insulation, decoration, etc. The spraying process for plastic products is a common surface treatment method. Through this method, plastic products can achieve various effects, such as changing colors, improving weather resistance, enhancing hardness and scratch resistance, hiding surface defects, adjusting surface gloss, improving electrostatic properties, etc.

[0003] After retrieval, the patent document with the publication number: CN213468289U discloses a surface spraying device for plastic products. By turning the handle, the rotating screw can be rotated, and thus the distance between the sponge pads installed at the other ends of the two rotating screws can be adjusted. In this way, plastic products of different lengths can be clamped, and the sponge pads play a certain protective role for the plastic products. The three-phase asynchronous motor can drive the moving block to move left and right. The spraying head installed at one end of the hose can automatically spray the clamped plastic products through the left and right movement of the moving block, and the stable power of the three-phase asynchronous motor can ensure the smooth left and right movement of the moving block, so as to achieve a certain degree of uniform spraying.

[0004] When the above device is actually used, the plastic products need to be fixed by clamping them relatively tightly between two sponge pads. During the spraying of the same batch, it is necessary to install and disassemble them back and forth. Since it is not easy to pick up the plastic products after spraying on the outer surface, waiting time is generated in the middle, reducing the efficiency. At the same time, it is not conducive to the recovery of excess paint during the spraying process. Summary of the Utility Model
