Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of float glass production lines, in particular to a cold end drop plate lifting device for a float glass line. Background Art
[0002] Currently, cold-end technology in glass production lines is maturing. In float glass production, cold-end equipment primarily performs various inspections, cutting / cutting, surface protection, stacking, and packaging of the annealed glass ribbon during the production process, as well as transporting these processes. The main dropper of the glass production line primarily screens the glass for defects. Incomplete or defective glass sheets are transported to the crusher for crushing and remelting.
[0003] The working principle of the cold-end roller mainline drop plate structure in a float glass production line is to use the cylinder piston rod to drive the V-shaped crank to rotate around the V-shaped crank corner point, thereby driving all the drop plates to descend together. The existing glass production line drop plate lifting device adopts a lower support lifting mode. The cylinder pulls the rotary crank to rotate. The wedge block is welded to the main beam of the drop plate. The top wheel moves on the wedge block to complete the lifting of the drop plate. This lifting device vibrates greatly during operation, which can easily cause the glass plate to shatter. In addition, the upper and lower lifting heights are fixed, and it is difficult to adjust them in time when the roller elevation changes. It is also easy for the glass plate to hit the rear roller, causing damage to the glass plate. The above two situations will affect glass production, reduce the glass yield rate, and increase production costs. Summary of the Invention
