The collection methods in the prior art are: crushing online recycling and conventional curling. Powder will affect the environment of the entire dust-free workshop during the crushing and recycling process, and the noise is loud. The unloading work after traditional curling is complicated and easy to cause defects due to broken edges. Not only does it require the core to be replaced every time, but the operation is also troublesome. In particular, the high-viscosity self-adhesive protective film is prone to adhesion, resulting in broken film and loss.
