Description

Technical Field

[0001] This utility model relates to the field of bag production technology, specifically to a trimming device for bag production. Background Technology

[0002] Bags and luggage are a general term encompassing all kinds of bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags, and various types of rolling suitcases. After 20 years of rapid development, China's bag and luggage industry now accounts for more than 70% of the global market share. Bags and luggage can be classified by material into leather bags, fabric bags, plastic bags, and metal bags. During the injection molding or compression molding process of rigid bags such as plastic and metal bags, excess material or overflow may occur at the edges, requiring the use of edge trimming equipment to remove excess material.

[0003] Existing edge-trimming equipment used in bag manufacturing may pose safety risks such as flying chips and knife injuries during the edge-trimming process of rigid bags. Additional safety measures are required, such as using a protective box to cover the edge-trimming equipment and protect the bags being edged from flying chips or knife injuries. During the edge-trimming process, due to the friction between the material and the knife, the chips may become statically charged and be attracted to the nearby protective box. To prevent chip accumulation and adhesion, the chips on the inner wall of the protective box need to be cleaned afterward. This requires workers to reach into the protective box to clean, increasing the workload, labor intensity, and reducing work efficiency of the workers. Utility Model Content

Then, the two first motors 12 are started, and the two first motors 12 drive the first threaded rods 13 fixedly connected to them to rotate, so that the two first threaded rods 13 drive the connecting plates 9 respectively threaded to them to move backwards. The two connecting plates 9 drive the two brushes 10 to move synchronously, pushing the debris on the upper surface of the workbench 1 into the connecting hole 8, and then into the collection box 6 through the connecting hole 8 to clean the debris on the inner wall of the protective box 2. The debris thrown onto the door of the protective box 2 can be cleaned off when the staff opens the door.
