Description

Technical Field

[0001] The present invention relates to the technical field of packaging belt crushing and recycling equipment, and particularly relates to an automatic shredder for PV packaging belts of cartons. Background Art

[0002] At present, the sliced tobacco box packaging in each tobacco factory uses inner and outer cartons, and the cartons are tied with PV packaging belts for packing. During production, it is necessary to disassemble the packed sliced tobacco boxes to take out the internal sliced tobacco for processing. The existing method for removing the PV packaging belts on the sliced tobacco boxes generally involves mechanical hands or manual cutting. After the PV packaging belts are cut by industrial mechanical hands or manually, they are extracted and thrown aside. Because the PV packaging belts are relatively long, on-site collection is very inconvenient, resulting in the need for manual sorting at the operation site to remove interference. At this time, since the manual processing operation area coincides with the working radius of the industrial robot, it is necessary to stop the production line. After the manual processing is completed, the production line is restarted again, affecting the processing efficiency of the production line. Therefore, a device is needed to clean the cut PV packaging belts to prevent the cut PV packaging belts from scattering on the ground and affecting production. Summary of the Invention
