Continuous squeezing force deviation-eliminated roller using atmospheric pressure as squeezing power

Abstract

Disclosed is a continuous roll without pressing force deviation using atmospheric pressure as pressing power, comprising at least four rolls (1), wherein the four rolls (1) form a square arrangement, two ends of the rolls (1) are respectively provided with a sealing guard plate (6), a sealed cavity is formed between the rolls (1) and the sealing guard plates (6), and the sealing guard plates (6) on at least one side are provided with an air extraction port (10). A main water trough (3) is provided below the rolls (1). A vacuum sealed cavity is formed between the four rolls (1) and the sealing guard plates (6) at the two ends. When a textile passes through the sealed cavity, air contained therein is extracted, such that when the textile comes into contact with water, the textile can be easily soaked in the water, and no surfactant is required. Costs are low, results are good, no pollution is caused, and continuous production and operation can be achieved.

Description

technical field [0001] The invention relates to the technical field of textile and printing and dyeing machinery, in particular, it is a continuous non-deviation rolling roll which uses atmospheric pressure as power to generate squeezing capacity. Background technique [0002] In the textile printing and dyeing industry and related industries, wet processing is often used. The wet treatment in the prior art generally just soaks textiles such as cloths and yarns in water, but this treatment process takes a long time, and because the textiles contain air, it is difficult for water to completely soak the textiles. Less than expected effect. In order to improve this problem, in the prior art, chemicals such as wetting agents or surfactants are generally added to the water to improve the penetration capacity of water. However, the textiles treated in this way will be contaminated with chemical substances, which will affect the subsequent treatment process, and even affect peopl...

Problems solved by technology

However, the textiles treated in this way will be contaminated with chemical substances, which will affect the subsequent treatment process and even affect people's health, and the cost is high and the pollution is also large.
