Rolling machine air valve manual adjusting device

Abstract

The invention relates to the field of rolling machines, in particular to a rolling machine air valve manual adjusting device. The rolling machine air valve manual adjusting device comprises a body, amoving plate arranged on the body in a sliding mode and a driving mechanism; and an air port is formed in the body, moreover, the air port is located in the sliding range of the moving plate, and themoving plate is connected to the driving mechanism. The rolling machine air valve manual adjusting device has the advantages that the driving mechanism drives the moving plate to slide in the body, the air port is located in the sliding range of the moving plate, then opening and closing of the air port are achieved, meanwhile, the air volume can be flexibly adjusted through the size of the area of the part, shielded by the moving plate, of the air port, for the rolling machine air valve manual adjusting device, the opening degree of the moving plate can be visually controlled, the adjusting process is reliable, moreover, the manual adjusting device can work in a high-temperature environment for a long time, and is more suitable for production requirements, the influence caused by wind system faults on production is greatly reduced, meanwhile, the leakage quantity of air can be well guaranteed, then the production requirements can be met, moreover, the structure is relatively simple, the installation is convenient, the cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of calenders, in particular to a manual adjustment device for an air valve of a calender. Background technique [0002] The calender in the rolling glass production line is located between the melting furnace and the annealing kiln. Its main function is to hydraulically roll the molten glass into a glass ribbon of a certain thickness, and transport the glass ribbon into the annealing kiln through the wind system between the roller tables. Annealing belongs to the forming part of rolled glass. Generally, the air valve of the calender is adjusted by an electric actuator, but due to the high temperature in the forming area, the electrical components are prone to failure when working at high temperature for a long time, resulting in the inability to adjust the air volume, and the maintenance of the electric mechanism is relatively complicated, requiring professional technicians to overhaul , more importantly, the price o...
