A low-position pressure roller

Abstract

The invention discloses a low squeezing roller. The low squeezing roller comprises a metal roller core and a rubber layer, wherein the rubber layer is mainly composed of a bottom rubber layer, a buffering rubber layer and a surface layer, a gap layer is arranged in the buffering rubber layer and in a wavy hole shape, extends inwards from one end face of the buffering rubber layer and is of an impassable blind hole structure, and the gap layer is filled with hot airflow. According to the low squeezing roller in the scheme, sizing is uniform, soakage and superimposition are good, yarn permeation, consideration and enhancement of superimposition, reduction of horizontal stripe starch lumps and side laitance are obviously improved, the sizing film integrity is improved, yarn hairness is appressed, and the sizing quality is improved.

Description

technical field [0001] The invention relates to a squeeze roller, in particular to a low-position squeeze roller. Background technique [0002] When sizing the yarn on the sizing machine, multiple pairs of sizing rollers that cooperate with each other are often used to squeeze the yarn after being soaked in the sizing tank to squeeze out the excess sizing on the yarn and realize the sizing of the yarn. Sizing. The elasticity of the coating material on the surface of the pressure roller has a great influence on sizing. When the concentration, viscosity and decomposition degree of the slurry are constant and the speed of the sizing machine remains constant, the elasticity of the coating material on the pressure roller is not only directly related to It affects the size of the sizing rate, and also affects the ratio between the penetration of the sizing liquid and the coating, thus affecting the relationship between the reinforcement of the sizing, straightening and wear resis...

The elasticity of the coating material on the surface of the pressure roller has a great influence on sizing. When the concentration, viscosity and decomposition degree of the slurry are constant and the speed of the sizing machine remains constant, the elasticity of the coating material on the pressure roller is not only directly related to It affects the size of the sizing rate, and also affects the ratio between the penetration of the sizing liquid and the coating, thus affecting the relationship between the reinforcement of the sizing, straightening and wear resistance; the current structure of the pressure roller is in the sizing Sliding is easy to occur during the time, causing friction to cause hairiness of the sizing yarn, increasing the elongation of the sizing yarn, and prone to sizing spots in the transverse direction, especially the edge due to poor pressing, resulting in uneven drying, sticking to adjacent yarns, and increasing edge yarns beheaded
