Abstract

The present invention relates to apparatus and method of eliminating protecting film comprising the inner paint layer and the outer plastic layer from metal plate material. The apparatus includes a film cutting device, a film winding device, a polishing device and a cleaning device arranged successively on the frame. The method includes the following steps: unwinding the plate material, cutting the outer plastic layer in the edge of the film to be eliminated with the film cutting device, winding the plastic film with the film winding device, eliminating the paint layer with the polishing device and eliminating residual powder with the cleaning device. The present invention has high production efficiency and stable product quality.

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...
