Quick roll change device

Abstract

The invention relates to a rapid roll changing device. The rapid roll changing device comprises an upper levelling roll mechanism and a lower levelling roll mechanism; the upper levelling roll mechanism is fixed on the rack; limiting devices are arranged below the upper levelling roll mechanism; the limiting devices are movable limiting blocks; the lower levelling roll mechanism is fixed on a support; an adjusting device is arranged beside the lower levelling roll mechanism; the adjusting device consists of a fixed support and a rotary beam; the rotary beam consists of a fixed beam and a rotary limiting beam; jacking devices are arranged below the lower levelling roll mechanism; the jacking devices are arrayed below the lower levelling roll mechanism in a pressure-sharing manner; and the jacking devices perform jacking and falling actions through oil cylinders. The jacking devices are arranged below the lower levelling roll mechanism, so that a lower levelling roll can be changed more conveniently; the lower levelling roll mechanism can be drawn out of a leveller rapidly through the effect of the jacking devices, so that the efficiency of changing the levelling roll mechanisms is improved; and the upper levelling roll mechanism is limited through the movable limiting blocks, so that the lifting of the upper levelling roll mechanism is facilitated.

Description

technical field

[0001] The invention relates to a device for replacing leveling rollers on a leveling machine, in particular to a quick roller changing device. Background technique

[0002] The leveling machine is widely used in industrial production. The leveling machine will level the plate through the action of the upper and lower leveling rollers, so that the plate can achieve a better curvature. When the upper and lower leveling rollers are used, the upper and lower levels will be adjusted. There is a lot of oil on the leveling rollers. It takes a lot of time and manpower to clean the upper and lower leveling rollers, and it is not easy to clean the leveling rollers on the leveling machine, which affects the leveling quality of the leveling machine. Since the leveling machine used to replace the leveling rollers, the leveling rollers could only be pulled out from the frame by manpower. This working method requires a lot of manpower to replace the leveling rollers, which...
