Cold-end falling plate lifting device used in float glass production line

Abstract

The invention discloses a cold-end falling plate lifting device used in a float glass production line, and the lifting device can guarantee stable lifting and descending operation of a cold-end falling plate. The lifting device comprises a frame, a cylinder and a V-shaped crank all of which are arranged below the cold-end falling plate, wherein the base of the cylinder is hinged on the frame, the corner of the crank is hinged with the frame, one end of the crank is hinged with the cold-end falling plate, and the other end of the crank is connected with a piston rod of the cylinder through a joint bearing. The lifting device has the advantages that: after the crank is connected with the piston rod of the cylinder through the joint bearing, the abrasion between the end part of the piston rod and the crank is avoided, the stable lifting and descending operation of the cold-end falling plate is guaranteed, and the service life of the cold-end falling plate lifting device is prolonged.

Description

technical field [0001] The invention relates to a float glass production line, in particular to a cold-end dropping plate lifting device in the float glass production line. Background technique [0002] At present, the cold end technology of the glass production line is becoming more and more mature. The cold-end drop plate device of the glass production line includes a cold-end drop plate, a rotating main shaft hinged to one end of the cold-end drop plate, a frame, a cylinder, and a V-shaped crank arranged under the cold-end drop plate, and a row of rollers are arranged on the cold-end drop plate , the base of the cylinder is hinged on the frame, the corner of the crank is hinged with the frame, one end of the crank is hinged with the cold end drop plate, and the other end of the crank is connected with the piston rod of the cylinder through a pin. When the glass production line is working, the cold end drop plate needs to be lifted frequently, but this will cause wear bet...

AI Technical Summary

Problems solved by technology

When working in the glass production line, the cold-end falling plate needs to be lifted frequently, but this will cause wear between the pin shaft and the end of the crank, and the long-term wear between the pin shaft and the end of the crank will cause There is a large gap, and when the falling plate is raised and lowered, the roller table will shake, which will have a great impact on the bearing at the hinge joint between the falling plate and the rotating spindle. The bearing is easily damaged, which will affect the normal operation of the falling plate and cause the glass plate to deviate. If the two glass plates are conveyed at the same time, it will also cause the two glass plates to collide with each other, resulting in damage to the glass plates
