Corrugated paper cross cutting machine knife roller

Abstract

The invention relates to a knife roll for a transverse cutting machine for corrugated paper. The knife roll comprises a roll body and shaft heads, wherein the shaft heads are arranged at the two ends of the roll body and used for supporting and transmitting power. The roll body comprises a steel lining and a laying layer with a certain thickness, wherein the laying layer is formed by making carbon fiber wound around and cured on the outer circle of the lining. A knife rest, a balance weight strip and a paper guide ring are mounted on the laying layer. The knife rest and the balance weight strip are symmetric about the axis. The paper guide ring is located near the knife rest, and cutters are fixedly arranged on the knife rest. The knife roll is made of a carbon fiber composite and has the beneficial effects of being low in inertia, high in rigidity, low in power, low in energy consumption, small in diameter and high in speed.

Description

technical field [0001] The invention relates to a corrugated paper cross-cutting machine equipment, in particular to a corrugated paper cross-cutting machine knife roller. 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 corrugated paper cross-cutting machine is an important equipment in the corrugated paper production line. Its function is to cut the formed corrugated board according to the length required by the user. The steel knife roll is the main type of the corrugated paper cross-cutting machine knife roll. When the width continues to increase , When the speed continues to increase, the use of steel knife rollers can no longer meet the requirements of mechanical performance improvement. How to ensure the stable and low-consumption work of the corrugated pa...

Problems solved by technology

The corrugated paper cross-cutting machine is an important equipment in the corrugated paper production line. Its function is to cut the formed corrugated board according to the length required by the user. The steel knife roll is the main type of the corrugated paper cross-cutting machine knife roll. When the width continues to increase , When the speed continues to increase, the use of steel knife rollers can no longer meet the requirements of mechanical performance improvement. How to ensure the stable and low-consumption work of the corrugated paper cross-cutting machine is an important issue under the condition of continuous increase in width and speed.

[0003] At present, the diameter of the knife roll of the corrugated paper cross-cutting machine is mostly small, and the small diameter knife roll may cut the paper when it runs at high speed. In order to overcome this problem, the current solution is to increase the outer diameter of the knife roll, adjust Cross-section, to obtain a large moment of inertia, although the large-diameter knife roller can meet the requirements of high-speed paper cutting, but its mass and inertia are large, and the knife roller will vibrate during the movement, which will aggravate the wear of the knife roller and make the The paper cutting quality of the knife roller is reduced, and the energy consumption and consumables of the paper cutting process are serious, which increases the processing cost, and the steel knife roller will be seriously deformed in the long-term working process, which will easily lead to the situation of cutting and breaking the paper
