Description

Technical Field

[0001] The utility model relates to the technical field of material transmission, in particular to a bag breaking and feeding device. Background Art

[0002] When recycling waste paper, the raw materials are mostly packaged and transported to the factory. The packaging bags are mostly plastic bags or nylon woven bags. When the materials are put into the production equipment, they need to be disassembled bag by bag, which increases labor, wastes time and effort, and slows down production efficiency.

[0003] In order to improve efficiency, many companies use bag breaking equipment to break bags and feed materials. The current bag breaking equipment puts the bagged products directly into the cutting roller to cut the bag body. However, this method can easily cause the bag body to be entangled on the blade, and it is more likely to cause the bag body to break and mix into the material, affecting product quality. It is also not convenient for the subsequent collection and processing of the bag body, which needs to be improved.

[0004] Therefore, those skilled in the art are in urgent need of developing a bag breaking and feeding device. Utility Model Content
