Pressure-assisted weaving and dyeing compression roller capable of preventing pressure non-uniformity of middle edges

Abstract

The invention discloses a pressure-assisted weaving and dyeing compression roller capable of preventing the pressure non-uniformity of middle edges. The compression roller comprises a pair of compression roller bodies, wherein rubber layers are coated on the outer sides of the compression roller bodies; the two sides of the compression roller bodies are provided with a metal roller respectively; pressurization devices are arranged on the outer sides of the metal rollers; and the pressure directions of the pressurization devices penetrate through the axes of the metal rollers and the compression roller bodies. According to the pressure-assisted weaving and dyeing compression roller capable of preventing the pressure non-uniformity of the middle edges, pressing blocks are tightly pressed on the metal rollers to apply pressure onto the metal rollers, and the metal rollers are used for transmitting the pressure to the compression roller bodies to prevent the compression roller bodies from deforming, so that the pressure of the compression roller bodies is uniformly applied, and the problem of chromatic aberration of the middle edges is solved. The pressing blocks cannot be directly contacted with the rubber layers on the outer sides of the compression roller bodies by transmitting the pressure of the pressing blocks through the metal rollers, so that the rubber of the compression roller cannot be abraded, and the service life of the compression roller cannot be influenced.

Description

technical field [0001] The invention relates to the field of textile and printing and dyeing finishing machinery, in particular to a textile dyeing press roller which can be assisted by pressure to prevent uneven pressure on the middle side. Background technique [0002] In the field of textile and printing and dyeing finishing, textiles need to pass through rollers during dyeing, wet processing or dry processing. However, because the pressure rollers are generally supported by bearing assemblies at both ends of the shaft of the pressure rollers, the two ends of the pressure rollers can be tightly squeezed to each other due to the limitation of the bearings, but the outside of the middle part of the pressure rollers is less restricted , the pressure roller will be deformed, causing the pressure in the middle of the pressure roller to decrease. This results in uneven pressure at the middle and both ends of the press roller, which ultimately leads to inconsistent liquid absor...
