Pressure device of calendaring machine

Abstract

The invention discloses a pressure device of a calendaring machine, and relates to the field of calendaring machines. The pressure device comprises a supporting frame and a self-pressing device; the supporting frame is fixedly connected to a machine base of a main calendaring machine, and the self-pressing device is fixedly connected to the supporting frame; the self-pressing device comprises a pneumatic mechanism and a pressurizing mechanism; the pneumatic mechanism comprises an airbag, a first connection pipe and an inflation pump, one end of the first collection pipe is communicated with aninternal cavity of the airbag, and the other end of the first connection pipe is connected with the inflation pump; the pressurizing mechanism is arranged over an upper roller of the main calendaringmachine body, and the airbag presses the upper roller of the main calendaring machine body through the pressurizing mechanism. The pressure device has the advantages that a pressure transfer chain issaved, a pressure value of the calendaring machine is more stable, and the qualification rate of glass is increased.

Description

technical field [0001] The invention relates to the field of calenders, in particular to a pressure device of a calender. Background technique [0002] In the glass calendering production line, the calender is the key equipment for glass forming. When producing thin glass, the pressure between the upper roll and the lower roll of the calender is not enough to make the glass thinner, so an additional pressure device is needed to force the upper roll down to ensure the thickness of the glass. [0003] The existing pressure device has the following defects: 1. The transmission chain of the pressure is: the upper roller, the pressure bar device, the lever mechanism, the support platform, the concrete foundation of the workshop, the base of the calender, and the lower roller. The transmission chain of the pressure is too long, It makes the elastic deformation and vibration difficult to control, and finally leads to unstable pressure value, resulting in a low qualified rate of gl...

AI Technical Summary

Problems solved by technology

The pressure transmission chain is reduced, the pressure value of the calender is more stable, and the qualification rate of the glass is improved; the pressure does not need to be transmitted through the concrete foundation of the factory building, which reduces the requirements for the civil design and construction of the factory building; the air pump can pass through the connecting pipe Set in a low temperature area, it solves the problems of easy damage, short life, high failure rate and low accuracy of electrical components caused by high temperature environment; no need to install a large platform, which reduces construction costs and construction time
