Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, and in particular to a scrap collection device for paper product processing. Background Technology

[0002] Paper products refer to paper products made from paper and paperboard as raw materials through further processing. Their advantages include high cost performance, good elasticity and toughness. The paper packaging industry has a wide variety of products, mainly including three categories: corrugated paper, honeycomb paper and embossed paper. Paper packaging derived from these three categories includes cartons, paper boxes, paper bags, paper cans, pulp molding, etc. Among them, cartons, paper boxes and paper cups are the products with the largest sales volume in the industry market.

[0003] Chinese Patent CN222287495U discloses a scrap collection device for paper product processing. Specifically, it discloses a method for sweeping scraps into a hopper, conveying them through a conveying mechanism to the interior of a housing, and using a baffle mechanism to block scraps from entering the housing, facilitating pulverization. A first drive motor rotates a mounting rod inside the housing, causing the pulverizing blades to further pulverize the scraps, thus improving collection efficiency and facilitating subsequent reuse. While this patent effectively conveys, pulverizes, and collects scraps, it suffers from several drawbacks. The scraps are often long and narrow, easily tangling around the pulverizing blades, resulting in low pulverization efficiency. Furthermore, the limited rotation angle of the baffle mechanism slows the pulverization of scraps passing through it, further reducing collection efficiency. Therefore, there is an urgent need for a scrap collection device for paper product processing that can solve the problem of low pulverization efficiency caused by long, narrow scraps tangling around the pulverizing blades and improve the collection efficiency of pulverized scraps.
