High-precision corrugated paper die cutting device based on rigid contact

Abstract

The invention discloses a high-precision corrugated paper die cutting device based on rigid contact. The high-precision corrugated paper die cutting device comprises a die cutting roller and a cushion roller which are matched with each other, a die cutting plate is installed on the die cutting roller, outwards-protruding cutter lines and pressing lines are distributed on the die cutting plate, a rigid cushion plate is installed on the cushion roller, and a plurality of die cutting grooves are distributed in the rigid cushion plate. When a corrugated board is subjected to die cutting, the cutter lines and the surface of the rigid cushion plate are correspondingly located on the upper side and the lower side of the corrugated board for die cutting operation, the pressing lines and the die cutting grooves are correspondingly located on the upper side and the lower side of the corrugated board for indentation operation, and the cutter lines and the pressing lines on the die cutting board are in rigid contact with the rigid cushion plate. The rigid cushion plate is installed on a cushion roller to replace a traditional rubber cushion roller for use, the die cutting grooves are formed in the rigid cushion plate, in the application process, on one hand, rigid contact is formed between the cutter lines and the rigid cushion plate, the phenomena of deviation, dislocation and the like of corrugated boards can be effectively avoided, on the other hand, the die cutting grooves are matched with the pressing lines, and the indentation with accurate positioning can be ensured to be formed.

Description

technical field [0001] The invention relates to the field of corrugated paper printing equipment, in particular to a high-precision corrugated paper die-cutting device based on rigid contact. Background technique [0002] In the process of corrugated cardboard printing and processing for packaging, corrugated cardboard often needs to obtain pre-designed shapes or cut marks. Therefore, die-cutting machines are one of the essential equipment for corrugated cardboard printing and processing. As the core mechanism of the die-cutting machine, the die-cutting roller group is mainly composed of a matching die-cutting roller and a rubber pad roller. When the corrugated cardboard passes through the gap between the die-cutting roller and the rubber pad roller, cutting marks and indentations are formed on the corrugated cardboard by using the knife line and the pressing line respectively. [0003] In the die-cutting roller set of a traditional die-cutting machine, since the surface la...

Problems solved by technology

However, in practical applications, with the continuous grinding and repair of the rubber pad roller, its surface accuracy will actually continue to decline; in addition, because the surface layer of the rubber pad roller is still a flexible rubber pad material, during the die-cutting process, with the The surface layer of the rubber backing roller is squeezed, and the corrugated cardboard is prone to misalignment and offset, especially for large corrugated cardboard. This phenomenon is more obvious, which leads to the inability to effectively improve the die-cutting accuracy and easily affects product quality.
