Description

Technical Field

[0001] The utility model relates to the technical field of paper tubes, and particularly to a wear-resistant fiber winding paper tube. Background Art

[0002] As a low-cost material, paper tubes are applied to multiple industries such as textile and chemical fiber, and are commonly used as spools, which are winding shafts for carrying filaments, yarns or other fiber materials. Their structures and performances directly affect the use effects and production efficiencies. The structures of traditional paper tubes are mostly cylindrical and are composed of paper tube substrates made of pulp. Although they have certain strength and stiffness, when running at high speeds during winding and bearing large winding forces, problems such as deformation and cracking are likely to occur, which limits their use in high-end application fields.

[0003] In order to improve the strength and wear resistance of paper tubes, in the prior art, there has been a practice of attaching reinforcement layers on the inner and outer sides of paper tube substrates. However, these reinforcement layers are usually made of a single material and cannot meet the changing use environments and higher performance requirements. In addition, the structural designs of existing paper tubes are relatively simple and lack effective limiting and shaping mechanisms, resulting in easy deformation or instability during the winding process, which affects the winding quality and production efficiency. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model relates to a wear-resistant fiber winding paper tube, which has a simple and reliable structure and effectively solves the above technical problems and is suitable for popularization and use. To achieve the above purpose, the utility model is realized through the following technical solutions:

[0005] A wear-resistant fiber winding paper tube includes a paper tube substrate. An inner reinforcement layer is arranged on the inner side of the paper tube substrate, and an outer protection layer is arranged on the outer side of the paper tube substrate. The paper tube substrate is of a polygonal structure. Limiting and shaping covers are symmetrically arranged on both sides of the paper tube substrate. The shapes of the limiting and shaping covers are adapted to the paper tube substrate and cover the outer side thereof. The two limiting and shaping covers are fixedly connected by a positioning rod.

[0006] On the basis of the above solution and as a preferred solution of the above solution: The inner reinforcement layer is made of glass fiber, and the outer protection layer is made of polyethylene fiber.

[0007] On the basis of the above solution and as a preferred solution of the above solution: External threaded columns are arranged at both ends of the positioning rod. A stepped through hole is arranged in the middle of the limiting and shaping cover. The small hole of the stepped through hole allows the external threaded column of the positioning rod to pass through, and a nut is installed in the large hole of the stepped through hole. The nut is threadedly connected to the external threaded column of the positioning rod.

A support shaft is arranged on the installation seat, and the support shaft coincides with the axis of the paper - tube base body. The support shaft is used for docking with the driving system of the winding equipment.

[0009] On the basis of the above - mentioned solution and as an optimal solution of the above - mentioned solution: The cross - section of the paper - tube base body is hexagonal.

[0010] The prominent and beneficial technical effects of the present utility model compared with the prior art are as follows: By arranging an inner reinforcement layer inside the paper - tube base body and an outer protection layer outside, the strength and wear resistance of the paper tube are significantly improved. The design of the polygonal structure increases the stability and support force of the paper tube, and has higher efficiency during stacking because they can fit seamlessly with each other to form a stable stacking structure, are arranged more closely, reduce space waste, provide a uniform tension distribution, contribute to keeping the material flat and reducing damage during the winding process, while the setting of the limiting and shaping cover and the positioning rod ensures the stability of the paper tube during use and effectively prevents deformation during the winding process.
