Description

Technical Field

[0001] The utility model relates to the field of aluminum foil production, in particular to a grinding wheel replacement device for a grinder. Background Art

[0002] During the aluminum foil production process, the rolling mill changes the thickness of the aluminum foil through the force exerted by the rollers on the surface of the aluminum foil until the ideal thickness requirement is reached.

[0003] When rolling aluminum foil of different passes, different alloys, and different finished thicknesses, the requirements for the roughness and crown of the roller surface are different. At this time, the roller needs to be ground on a CNC grinder to meet the required standards. Rollers of different standards require corresponding grinding wheels for grinding.

[0004] In the prior art, when replacing the grinding wheel of a CNC grinder, two people are usually required to cooperate to dismantle and lift the existing grinding wheel, and then lift the required grinding wheel up and install it, which is inefficient. In addition, since the grinding wheel is heavy, two people need to cooperate closely with each other. If the cooperation is improper, the grinding wheel may fall, which may cause personal safety accidents, grinding wheel damage, equipment damage and other problems. Summary of the invention
