[0002] Papermaking is an important invention of the working people in ancient China. It is divided into two forms: mechanical and manual. The mechanical process is carried out continuously on a papermaking machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and initially dehydrated on the wire section of the papermaking machine to form wet paper sheets, which are then pressed for dehydration and then dried into paper.

[0003] The prior art (patent number: CN217174176U) discloses a new type of rubber roller for papermaking in a paper mill, including a base, a group of fixing frames are fixedly installed on the left and right ends of the base, the two groups of fixing frames are symmetrically distributed on the left and right, and each group is set to two, and fixing bolts are inserted and installed on the upper ends of the two groups of fixing frames.

[0004] The existing special rubber rollers for paper mills have the following disadvantages. When the existing rubber rollers are in use, the paper scraps remaining on the surface of the rubber rollers are not easy to clean, which affects the secondary use of the rubber rollers. In addition, the length of the existing rubber rollers is fixed, but the sizes of the papers are different. Therefore, when the papers are wound, the width of the papers is smaller than the length of the rubber rollers, so the papers will become loose when wound, which makes the equipment have certain limitations. Therefore, we propose a new type of special rubber roller for paper mills. Utility Model Content
