Description

Technical Field

[0001] The present invention relates to the technical field of printing waste treatment, and in particular to a non-stop waste discharge and collection system and method. Background Art

[0002] In the label printing industry, most flexographic printing machines are equipped with non-stop unwinding, non-stop rewinding and non-stop waste disposal devices to achieve non-stop processing of printing waste. The waste in the label printing industry is generally strip-shaped scraps that need to be torn off from the paper after die-cutting. The waste discharge device in the existing technology is generally winding and rewinding through a winding drum.

[0003] However, the diameter of the winding drum for collecting waste materials in the existing waste discharge device cannot be infinitely increased. After being wound to a certain extent, it needs to be disassembled and processed. At this time, the printing machine needs to be stopped for processing. The printing machine can continue to work after the winding drum processing is completed. The existing waste discharge post-processing devices simply carry out winding processing and then directly pack them. These wastes have different shapes and sizes. The waste processed in this way will take up a lot of storage space, which is not conducive to centralized storage; resulting in low working efficiency of the entire waste discharge and collection system. Summary of the invention

[0004] The purpose of the present invention is to provide a non-stop waste discharge and collection system to address the deficiencies in the prior art.
