Knife roll of corrugated paper cross cutting machine

Abstract

The invention relates to the technical field of transverse cutting machines, in particular to a corrugated paper transverse cutting machine knife roller. The knife roller comprises a rotating shaft, wherein the center of the rotating shaft is fixedly and coaxially sleeved with a first cylinder; supporting rods are welded to the outer circumferential side surface of the first cylinder at equal intervals; the first cylinder is coaxially sleeved with a second cylinder; one ends, away from the first cylinder, of the supporting rods are welded to the inner circumferential side surface of the secondcylinder; inverted T-shaped inserting grooves are formed in the side surface of the outer circumference of the second cylinder at equal intervals; a cutter assembly is fixedly arranged in one of theinserting grooves and comprises an inserting plate; and the inserting plate is inserted into the inserting groove. According to the knife roller, the cutter assembly is fixed in the inserting groove of the second cylinder through fastening bolts, when a cutter in the cutter assembly is passivated or damaged, a worker can conveniently maintain or replace the cutter assembly by detaching the fastening bolts, and the service life of the knife roller can be prolonged.

Description

technical field [0001] The invention relates to the technical field of cross-cutting machines, in particular to a knife roller of a cross-cutting machine for corrugated paper. Background technique [0002] In recent years, the production speed of the corrugated cardboard packaging industry has been continuously refreshed, so more and higher requirements have been put forward for the equipment in the corrugated paper production line. The cross-cutting machine belongs to the carton processing machinery. In the corrugated cardboard production line, the assistance of the cross-cutting machine must be indispensable. The cross-cutting machine is a mechanical device for cutting the finished cardboard. Its technical performance and equipment adjustment directly affect whether the cutting size of the finished cardboard is accurate and whether the crimping line is accurate. Cracks and whether the appearance of the incision is smooth and beautiful. When the knife roller installed on ...

AI Technical Summary

Problems solved by technology

When the knife roller installed on the cross-cutting machine is used for a long time, the cutting knife on the knife roller is prone to passivation or damage, and the cutting knife is not easy to disassemble from the knife roller for replacement. cause waste of resources
