Description

technical field

[0001] The invention relates to the processing equipment and method of the metal wall plate of the refrigerated container, in particular to the equipment and method of removing the protective film of the aluminum wall plate. Background technique

[0002] In the design of refrigerated boxes or refrigerated trucks, pre-painted aluminum panels are often used as the wall panels of the box body, and are typically used as the inner roof panel. The following takes the treatment process of the inner roof plate of the refrigerator as an example to illustrate. As shown in Figure 1, the aluminum plate 1 used as the inner top plate is generally a pre-coated aluminum plate, and an anti-oxidation and anti-corrosion paint film 12 is sprayed on its aluminum surface 11 as a protective layer. In order to prevent the film from being damaged, its Outer surface has used one deck plastic film 13 to cover again. According to the production requirements of the refrigerator, in ord...
