AI Technical Summary

Technical Problem

Traditional pressing rollers come into direct contact with the fabric surface, resulting in high friction and wear on the fabric, especially the edge fabric, which is severely worn under tension, affecting the quality of the fabric.

Method used

The outer roller and enclosed disc, made of carbon fiber nylon material, combined with a liquid circuit and adjustable liquid mass, control the pressure by adjusting the weight of the roller body, replacing the traditional metal roller body and fixed bracket.

Benefits of technology

This technology allows for pressure adjustment by adjusting the weight of the roller without using an adjustable bracket, thereby reducing friction, protecting the fabric surface, and improving the quality of the greige fabric.

Abstract

According to the cloth pressing roller, an existing cloth pressing roller is usually made of metal, the downward pressing force is usually constant, the downward pressing force of the cloth pressing roller can only be adjusted and controlled through supporting equipment, and therefore friction force generated by downward pressing is adjusted. When a programmable and adjustable cloth pressing roller bracket is not arranged, especially in a traditional nylon belt hanging mode, a traditional cloth pressing roller is extremely prone to generating large friction force, and serious abrasion is caused to a cloth cover. The cloth pressing roller comprises an outer roller rod, a hollow shaft rod and a steering connector. Wherein the outer roller rod and the hollow shaft rod are coaxially arranged, and the hollow shaft rod is sleeved with the supporting discs at equal intervals; a steering joint is arranged at one end of the hollow shaft rod; the two ends of the outer roller rod are provided with closed round pieces, the closed round pieces are bonded with the outer roller rod, and the contact edges of the closed round pieces and the hollow shaft rod are bonded through a dissoluble adhesive.

Description

Technical Field

[0001] This utility model relates to weaving equipment, specifically to a fabric pressing roller. Background Technology

[0002] The function of the take-up device on a water-jet loom is to promptly and quantitatively guide the woven fabric away from the weft end and onto the take-up roller, according to the fabric's required weft density. This ensures that the weft end position does not change due to the introduction of new weft yarns, thereby guaranteeing continuous weaving production and forming a greige fabric package. Simultaneously, the flatness and uniform tension of the greige fabric during take-up are crucial factors affecting the package quality.

[0003] The traditional method of installing and fixing the pressure roller involves creating a suspension groove at the end of the pressure roller shaft and suspending it from the side panels of the loom using nylon straps. The pressure roller and the roll-up roller are in close contact before weaving. At the beginning of the roll-up stage, due to the small thickness and insufficient elasticity of the fabric roll, and the direct contact between the pressure roller and the roll-up roller, the friction between the metal pressure roller and the fabric surface is large, and the fabric surface is prone to severe wear. In particular, under the influence of the tension torque, the selvage fabric suffers more severe wear, which greatly affects the overall quality of the fabric. Summary of the Invention

[0004] This invention addresses the issue that existing pressure rollers are typically made of metal, with a constant downward pressure. The downward pressure can only be adjusted using a support device to regulate the friction generated by the downward pressure. Without a programmable and adjustable pressure roller support, especially with the traditional nylon belt suspension method, conventional pressure rollers are prone to generating high friction, causing severe wear on the fabric surface.

[0005] Therefore, this utility model provides a pressure roller, including: an outer roller rod, a hollow shaft rod, and a deflector joint;

[0006] The outer roller and the hollow shaft are coaxially arranged, and support discs are evenly spaced on the hollow shaft, with the outer ring of the support discs fitting with the inner wall of the outer roller.

[0007] At least one dividing disc is provided inside the hollow shaft, and a diverter joint is provided at one end of the hollow shaft. The cavity formed by the inner wall of the hollow shaft between the dividing disc and the diverter joint is designated as a liquid circuit.

[0008] Closed circular pieces are provided at both ends of the outer roller rod. The closed circular pieces are bonded to the outer roller rod and are bonded to the contact edge of the hollow shaft rod using a soluble adhesive.

[0009] At least two liquid inlet / outlet holes are provided on the hollow shaft where the liquid circuit is located, and a flexible hose is fitted over the liquid inlet / outlet hole. The length of the flexible hose is greater than or equal to the radius of the outer roller, and the flexible hose is installed inside the outer roller.

[0010] Preferably, the outer roller and the closed disc are made of carbon fiber nylon; the outer roller has a wall thickness of 2 mm, and the closed disc has a thickness of 2 mm or more.

[0011] Preferably, the support disc has several fan-shaped holes arranged symmetrically at its center, and the outer ring of the support disc is fitted with a 3-5cm wide outer peripheral support ring, which is fixedly connected to the support disc.

[0012] Preferably, the hollow shaft has a bearing fitted on the shaft body outside the closed disc, and the end without the steering joint is provided with a counterweight ring, the mass of which is equal to that of the steering joint.

[0013] The beneficial effects of this utility model are as follows: by using a main roller made of carbon fiber nylon material, the basic weight caused by the metal roller is effectively replaced. The actual total weight of the roller is adjusted by the degree of liquid filling, so that the roller pressure can be adjusted even without using an adjustable pressure roller bracket. Furthermore, the structure of this application has the characteristics of being more adaptable. Attached Figure Description
