Large overfeed roller for textile machinery

A technology of textile machinery and large overfeeding, which is applied to the elongation of fabrics, textiles and papermaking, and fabric surface trimming. It can solve the problems of inability to adjust the speed of large overfeeding rollers in real time, inconvenient transportation and installation, and large moment of inertia. Achieve the effect of reducing the moment of inertia and mass, ensuring stable rotation and stable structure

Problems solved by technology

Most of the large overfeeding rollers used in the textile industry are solid cylindrical metal rollers. Such large overfeeding rollers have the following obvious disadvantages: one is that the weight is too heavy, and it is inconvenient to carry and install; the other is that the moment of inertia is too large. When overfeeding, the speed of the large overfeeding roller cannot be adjusted immediately

Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the preferred embodiment of the large overfeed roller on a kind of textile machine of the present invention is described in detail:

[0021] Such as figure 1 As shown, the main body of the large overfeed roller is a concentric steel sleeve outer ring 1, a mandrel 2 and a plastic part 3 that fixes the relative positions of the two. The outer ring 1 of the steel sleeve is a steel cylinder, the outer surface is polished smooth, and the inner wall is provided with internal anti-slip lines 11, which are cross internal threads; the mandrel 2 is a steel round stick shaft, which is concentric with the outer ring 2 of the steel sleeve. There are outer anti-slip lines 21 on the surface of the shaft 2, which are reticular patterns, and the part of the mandrel 2 located in the outer ring 2 of the steel sleeve is polished into a special-shaped shaft 22, which is a section of cylindrical shaft with two short planes on the surface. Shaf...

Abstract

The invention relates to common components on textile machineries, and especially relates to a large overfeed roller for a textile machinery. The large overfeed roller comprises a steel sleeve outer ring (1) and a core shaft (2) which are concentric to each other. The relative position between the steel sleeve outer ring (1) and the core shaft (2) is fixed through an integrally molded plastic component (3). According to the present invention, the large overfeed roller is manufactured through fixing the relative position between the steel sleeve outer ring and the core shaft by the integrally molded plastic component, the overfeeding quality is ensured by the steel sleeve outer ring, and the mass and the inertia moment of the large overfeed roller is reduced with the plastic component, such that the installation and transportation of the large overfeed roller are convenient, and the rolling speed of the large overfeed roller can be adjusted in time.

Description

technical field [0001] The invention relates to common parts on textile machinery, in particular to a large overfeeding roller on textile machinery. Background technique [0002] During the dyeing and finishing process of textiles, a large tensile force is received in the warp direction, resulting in elongation of the piece length and narrowing of the width. In order to overcome this unstable state and ensure the dimensional stability of the textile, a large overfeed roller is used to adjust the cloth feeding speed during tentering or setting. This is called overfeeding, and the large overfeeding roller is an essential part of overfeeding . Most of the large overfeeding rollers used in the textile industry are solid cylindrical metal rollers. Such large overfeeding rollers have the following obvious disadvantages: one is that the weight is too heavy, and it is inconvenient to carry and install; the other is that the moment of inertia is too large. When overfeeding, the spe...
