DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When in use, the aluminum-based copper-clad laminate is placed on the conveyor belt, and the protective film roll is placed on the reel.

[0030] Moreover, in actual application, the bracket is also provided with a coating pressing shaft roller 6, which is parallel to the unwinding frame; the conveyor belt travels from the unwinding frame to the coating pressing shaft roller; the symmetrical edge of the coating platform is provided with a limiting convex strip 7, and the conveyor belt is located between the two limiting convex strips. In this embodiment, the coating pressing shaft roller is mainly used to press the protective film and the aluminum-based copper-clad laminate to ensure the quality of the coating, and the limiting convex strip is mainly used to limit the aluminum-based copper-clad laminate to prevent it from shifting or tilting on the conveyor belt.
