[0002] At present, in the process of paper production, the production and processing personnel need to roll a large amount of paper. In the prior art, most of the base paper roll tube cores are used for auxiliary winding to facilitate later turnover. However, the base paper roll tube core is generally made of ordinary kraft paper, which is easily damaged during use. Once the end is damaged, the entire paper core tube is discarded. Therefore, the service life of the turnover paper core tube is very short and needs to be replaced frequently, which makes the production cost high.

[0003] To solve the above problems, after searching, a Chinese patent application numbered CN201310563379.2 discloses a glass fiber reinforced plastic paper core tube and a preparation method thereof, and its main technical features are: comprising a cylindrical glass fiber reinforced plastic tube body, the inner wall of the glass fiber reinforced plastic tube body is provided with a plurality of axial convex strips, a cylindrical adapter with end caps is inserted at both ends of the glass fiber reinforced plastic tube body, and the outer wall of the adapter is provided with a plurality of axial grooves matching the axial convex strips. The glass fiber reinforced plastic paper core tube and the preparation method thereof in the above patent have the following deficiencies: adapters are inserted at both ends of the glass fiber reinforced plastic tube body, and in order to increase the integrity of the glass fiber reinforced plastic tube body and the adapter, an adhesive layer is coated between the two. Although the stable winding of the paper roll can be achieved, the adapter is a consumable part. Once damaged, it is inconvenient to disassemble and replace it. Utility Model Content
