The invention discloses a refrigerator door lining stable edge
cutting device and a using method thereof, and relates to the technical field of refrigerator door lining production. The device comprises an outer frame, a built-in supporting frame is fixedly installed on the outer frame, a stable
cutting device is arranged on the built-in supporting frame, and a transverse reciprocating moving
assembly is arranged on the side, close to the stable
cutting device, of the built-in supporting frame; the refrigerator door lining obtained after plastic uptake is completed is moved to a
workbench through a mechanical arm and an electric suction cup
assembly; the driving
assembly is started, and the driving assembly drives the intermittent rotating assembly to perform quarter-circumference intermittent rotation; by arranging the driving assembly, the stable cutting device, the transverse reciprocating moving assembly and the refrigerator door lining burr removing and
grinding device, the driving device drives the stable cutting device to
cut the outer edge of the refrigerator door lining and drives the transverse reciprocating moving assembly to move in a reciprocating mode at the same time; and the transverse
reciprocating motion assembly drives the refrigerator door lining deburring and
polishing device to synchronously reciprocate.
