High linear pressure water-squeezing big roller and manufacturing method thereof

Abstract

The invention belongs to a high linear pressure big roller and a manufacturing method of the high linear pressure big roller. The high linear pressure big roller comprises a central spindle and a rubber layer covering the exterior of the central spindle. Six nylon reinforcement layers are added into the rubber layer to enhance the displacement prevention capability of the rubber layer and improve the tear-resistant performance of the rubber layer. The central spindle is an iron core, and the nylon reinforcement layers are made of nylon 66 cord fabrics. The manufacturing process comprises conducting abrasive blasting, cleaning, adhesive brushing, drying and mucilage brushing on the central spindle in sequence; after mucilage is dry, cord fabric straps and the rubber layer are wound around the central spindle through a winding type forming machine for forming, and then the central spindle is sequentially subjected to iron wire winding, vulcanization, iron wire dismantling, turning, inspection and warehousing to obtain the high linear pressure big roller. The actual service life of the rubber covered roller is up to six months according to manufacturers.

Description

technical field [0001] The invention relates to the field of a refining machine for viscose staple fiber production, in particular to a high-line extrusion water large roller on a refining machine for viscose staple fiber production. Background technique [0002] Viscose staple fiber manufacturing industry refiner upper high-line squeeze water large roll is used for squeeze water in the final oiling process of the refiner. The high-line squeeze water large roll is composed of a shaft core and a rubber layer covering the shaft core. The specifications and dimensions are generally: diameter: 580mm, length 3200mm, rubber thickness 25mm, iron core diameter 530mm, and the maximum line pressure involved in the work is 100kg / cm. The purpose is to squeeze out the moisture in the short fiber as much as possible, so as to facilitate the subsequent drying process. However, due to the uneven laying of the viscose staple fiber wool layer, unevenness, and the thickness of the wool layer ...

Problems solved by technology

[0005] 3. The rubber roller has the best water-squeezing effect and the price is reasonable. However, due to the unevenness of the water-squeezing pressure bearing (hair layer) and excessive local line pressure, it is easy to cause degumming of the water-squeezing rubber roller and the service life is too short.

If the thickness of the adhesive layer is reduced, the displacement can be reduced, but it will have an adverse effect on the water squeezing effect
