Rubber calender

Abstract

The invention relates to a rubber calender comprising a frame body, a feeding device, a calendering device, scraping devices, a cooling device and a discharging device. The feeding device is arrangedat the left side of the frame body, the calendering device is arranged in the middle of the interior of the frame body, the scraping devices are installed on the upper end face and the lower end faceof the interior of the frame body, and the cooling device is arranged at the front end of the frame body; and the discharging device is arranged at the right side of the frame body. According to the rubber calender, the following defects of a traditional rubber calender can be overcome: a, rubber is calendered into a common rubber sheet, and the cross section has no specific shape; b, in the calendering process, rubber is adhered to the surface of a working roller, so that the surface of a calendered rubber sheet is not smooth enough, and the calendering quality is influenced; and c, after therubber is calendered, the rubber is cooled too quickly, so that the shrinkage rate of the calendered rubber sheet is relatively high, and the calendering effect is influenced.

Description

technical field [0001] The invention relates to the field of rubber processing, in particular to the technical field of a rubber calender. Background technique [0002] Rubber calendering refers to the process of making rubber products into a film of a certain thickness, width or shape in advance. The principle is that when the rubber material is added between the two working rollers of the calender, the rubber material is brought into the nip by the rotation of the rollers, and the rubber material is rolled into a film with a certain thickness and width. [0003] At present, the traditional rubber calender usually has the following disadvantages: a. The rubber is calendered into an ordinary film, and the cross-section has no specific shape; Affect the quality of calendering; c. Cool down the rubber too quickly after calendering, resulting in a large shrinkage rate of the film after calendering, thus affecting the effect of calendering. Contents of the invention [0004]...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the following disadvantages usually existing in traditional rubber calenders: a. rubber is calendered into ordinary film, and the cross-section has no specific shape; b. during the calendering process, the surface of the calendered film is not smooth enough due to the adhesion of rubber on the surface of the working roller , which affects the quality of calendering; c. After rubber calendering, it cools down too quickly, resulting in a large shrinkage rate of the film after calendering, which affects the effect of calendering and other problems
