Silica gel calendering compounding machine

Abstract

The invention discloses a silica gel calendering compounding machine, comprising a rack and five rollers, wherein, the rollers are connected with the rack through a bearing pedestal, and each roller is respectively connected with an independent variable frequency motor. According to the invention, a plurality of variable frequency motors are used to independently drive each roller to enable the speed ratio among rollers to be arbitrary ratio, cooperate the reasonable collocation of distance between rollers and generate certain buildup between rollers, so that the quality defect of bubbles carried in the products can be solved, and the advantages of low electricity consumption, small volume, high production efficiency, labor saving and the like of the silica gel calendering compounding machine are achieved.

Description

technical field [0001] The invention relates to a calender compound machine, in particular to a silica gel calender compound machine. Background technique [0002] Existing calenders for the rubber industry. Mainly used for the production of silica gel (silicone) sheets, the composite production of silica gel (silicone) sheets and film / cloth, and the production or composite production of rubber sheets below Shore 50 degrees. The existing calender consists of two or more rollers arranged in a certain form, mainly composed of rollers, racks, roller distance adjustment devices, roller temperature adjustment devices, transmission devices, lubrication systems, feeding systems and control system etc. There are following shortcoming and deficiency in existing calender: [0003] (1) poor quality [0004] When producing thicker products (thickness above 1-2mm), there will be a large number of air bubbles in the produced product, and different degrees of poor quality will occur dep...

[0003] (1) poor quality

[0004] When producing thicker products (thickness above 1-2mm), there will be a large number of air bubbles in the produced product, and different degrees of poor quality will occur depending on the thickness. Although various measures are taken to eliminate air bubbles, quality defects cannot be solved. It is fundamentally overcome and cannot meet the quality requirements of silicone products in the electronics-related industries. The reason is that the existing calender drive device is driven by a single motor through a reducer and driven by gears. The speed ratio between the rollers is single and cannot be adjusted. Adapt to the matching requirements of different thickness silicone products for the mutual speed ratio of each roller;

[0005] (2) Low efficiency

[0006] Due to the use of a single motor drive, the speed ratio between the rollers is single and cannot be adjusted. When producing products with different
