Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carton waste paper processing, in particular to a waste paper processing device for carton green printing. BACKGROUND

[0002] Carton recycling is a multi-step process. First, the recycled cartons are compressed and packaged before being fed into a pulper, mixed with water and stirred into a paste-like pulp 34. Then the pulp is filtered to remove impurities (such as adhesives or cement residues) to ensure purity 45; after filtration, the pulp is sent to a large drum to spin dry and compress, forming a wet paper layer, which is then dehydrated by secondary compression to produce a raw paper board base layer, which can be compounded into multiple layers of paper board according to its intended use.

[0003] The core value of recycling is environmental protection and resource recycling. For example, corrugated cartons have a three-layer to seven-layer composite structure, and the utilization rate of recycled fibers is as high as 70%. Each ton of recycled paper reduces carbon emissions by 1.2 tons and saves 28 cubic meters of water compared to virgin pulp, significantly reducing environmental burden. At the same time, single-layer paperboard boxes can improve the brightness of recycled pulp by 15% through bioenzymatic technology, increasing the recycling value by 30%. The demand for e-commerce and logistics is driving the continued growth of the carton market.

[0004] In the prior art, the paper box green printing waste paper processing device disclosed in the publication "CN118357248A" includes a support leg fixedly connected to the bottom, a crushing transmission assembly fixedly connected to the top, a crusher fixedly connected to the top, a connection box fixedly connected to the top of the crusher, a connection disc fixedly connected to the top of the connection box, and a waste paper compression mechanism provided on the inner wall of the connection box. It relates to the technical field of waste paper processing. By setting the waste paper compression mechanism, the thread angle of the outer wall of the threaded rod is greater than 45 degrees, so the sliding sleeve can normally rotate and lift with low friction through the thread rotation, thereby driving the sliding sleeve, the rotating rod and the conical block to rotate synchronously. With the rotation of the conical block, the waste paper scraps on the surface will be thrown off by rotation, which will lose the friction force of static friction with the surface of the conical block, thereby sliding down the inclined surface of the outer wall of the conical block, improving the feeding effect of the waste paper scraps.

[0005] However, the prior art still has some shortcomings, such as: The above device and the prior art lack a tearing and peeling mechanism for the pattern layer on the surface of the paperboard before the waste paper is crushed, which makes the pattern layer on the surface of the waste paper pieces still firmly attached after the waste paper is crushed.
