Pressure-resistant and wear-resistant semi-arc type addendum metallic card cloth

Abstract

The invention discloses a pressure-resistant and wear-resistant semi-arc type addendum metallic card cloth and relates to the field of carding components of textile machinery. The addendum metallic card cloth solves the problems that since stressed areas of addendum ends of current metallic card cloths are small, the service life is short, bending and lodging are caused easily. Each tooth of the pressure-resistant and wear-resistant semi-arc type addendum metallic card cloth includes a tooth front surface, an arc top surface, a tooth back surface and a tooth root part connected with a base part, the tooth front surfaces and the tooth back surfaces are both linear, the junctions between the tooth front surfaces and the tooth back surfaces are connected through the arc top surfaces, and thearc top surfaces are arc-shaped and are inclined downward and slidingly connected with the tooth back surfaces. The pressure-resistant and wear-resistant semi-arc type addendum metallic card cloth iseasy to manufacture, high in pressure resistance and long in service life.

Description

technical field [0001] The invention relates to the field of carding components of textile machinery, in particular to a compression-resistant and wear-resistant half-arc tooth top metal card clothing. Background technique [0002] The carding part is the core equipment in the spinning process, and the metal card clothing is the most important element on the carding part. With the different properties of textile raw materials and fabrics, especially the wide application of various new fibers, higher requirements are put forward for the use of metal card clothing. The quality of metal card clothing is mainly reflected in smoothness, sharpness, wear resistance and flatness. and quenching uniformity. However, at present, the structure of metal card clothings is basically pointed tooth type. Recently, some metal card clothings with prismatic teeth and main and auxiliary tooth structures have also appeared, but the tooth types of existing metal card clothings are all straight to...

AI Technical Summary

Problems solved by technology

However, at present, the structure of metal card clothings is basically pointed tooth type. Recently, some metal card clothings with prismatic teeth and main and auxiliary tooth structures have also appeared, but the tooth types of existing metal card clothings are all straight tooth types. Type metal card clothing has the following disadvantages: 1. The fiber flow is constantly rubbing through the needle teeth, so that the tooth tips are gradually worn away. After the sharpness of the needle teeth declines, the quality of the yarn is seriously reduced, resulting in a greatly shortened service life of the metal card clothing; 2. Due to the small force-bearing area of ​​the metal card clothing tooth tip, that is, the weak compressive capacity, the teeth of the metal card clothing are easy to bend and fall under the action of a large external force when the metal card clothing is working; 3. Straight-tooth metal card clothing is processed When manufacturing instant punching teeth, large and small teeth are likely to be produced due to the motor on the punching machine and the running speed of the card clothing, and the metal card clothing with large and small teeth is covered on the drum, which will show poor flatness, that is, the hand feel is not good
