Description

Calender

Technical Field

The utility model relates to the technical field of calender equipment, in particular to a calender.

Background

In the plastic industry, the calender is a processing method for making the plastic mixed with various auxiliary agents, heated, plasticized and nearly viscous state, through the gap formed by two (or more than two) rollers rotating in opposite directions, under the action of the extrusion force and shearing force of the rollers, the plastic generates a certain extension deformation, thus obtaining the continuous lamellar products with required specification.

In calendaring production practice, 1-3 width roll gaps are typically provided before the final extrusion of the product, with a certain ratio between the two rolls of each gap being maintained. The accumulated materials in the roll gap can be rolled and flowed regularly under the condition of having a speed ratio, so that further mixing and plasticizing are carried out, the temperature, the internal uniformity and the plasticizing degree of the materials are fully improved, and part of volatile gases and mixed air can be removed.

Therefore, after the materials are subjected to thin pass, rolling and shearing through a certain number of roll gaps, the plasticizing and homogenizing effects of the materials are enhanced, and the method has positive effects on improving the quality of the rolled products. But the actual production speed ratio cannot be too large or too small. The speed ratio is too large, so that the temperature of the material in the roll gap is too high due to the friction force, and scorching or pyrolysis is easy to occur. The speed ratio is too small, the motion law of materials can be in an irregular state, the homogenization effect and the exhaust effect can be reduced, and air bubbles are formed in products in the air mixing materials easily, so that the precision and quality of products are affected.
