AI Technical Summary

Technical Problem

Fibers with high moisture content can easily wet the paper tube when wound on a regular paper tube, affecting its subsequent use.

Method used

It adopts a multi-layer composite paper tube structure, with a high basis weight kraft paper inner layer, a glass fiber mesh or aramid fiber paper middle layer, and a plastic-coated kraft paper outer layer. Combined with the design of inclined groove, limiting groove, anti-slip paper and plastic film, it enhances structural stability and water resistance. The raised points on the outside of the anti-slip paper increase friction, and the plastic film isolates moisture and contaminants.

Benefits of technology

It achieves both anti-slip and waterproof effects in humid environments, prevents the bottom yarn from sticking, facilitates unwinding later, and extends service life.

Abstract

The application relates to a fiber winding paper tube with high moisture content, belonging to the technical field of winding paper tubes, which comprises a main cylinder, the inner wall of the main cylinder is fixedly connected with two limiting rings, the left and right ends of the main cylinder are both provided with inclined grooves, the ends of the two inclined grooves close to each other are both provided with limiting grooves, the outer side of the main cylinder is provided with anti-skid paper, and the inner wall of the anti-skid paper is in sliding connection with the main cylinder. The main cylinder, the limiting ring, the inclined groove, the limiting groove, the anti-skid paper, the plastic film and other components are arranged, the anti-skid paper is horizontally slid into the main cylinder, then the plastic film is installed along the anti-skid paper, the waterproof film is coated on the outermost layer, the anti-skid convex is formed to ensure anti-skid, the waterproof effect is ensured on the basis of ensuring the anti-skid effect, the bottom wire is prevented from adhering to the paper tube while the anti-skid effect is ensured, and the effect that the device can facilitate the unwinding of the bottom wire in the later period is achieved.
