Description

Technical Field

[0002] After long-term struggle and opening up to the world, China's plastics industry has gradually formed a relatively complete industrial system and has become a basic material industry that is on par with steel, cement, and wood. As a new type of material, it is widely used. During the processing of plastic parts, glue needs to be applied to their surface to make them firmly bonded with other parts, thereby improving the functions of the plastic parts and allowing them to play a better role. At the same time, in order to speed up the coating work efficiency, a plastic part continuous coating machine is needed. For example, a coating machine is disclosed in a Chinese patent, and its application number is: CN201410187486.4. By adjusting the regulating valves of the transmission roller I and the transmission roller II, it can coat plates of different thicknesses. In addition, a tray is provided on the protective frame of the transmission roller II, which improves the safety of the operator. However, during the coating process, the object needs to be placed manually in the coating position and then taken out after the coating is completed. When performing continuous coating, manual repeated operations are required, which increases the labor intensity of the manual operation. In addition, the glue is easy to solidify during use, which will affect the bonding effect. Utility Model Content
