Description

Paperboard processing structure of creasing machine and creasing machine

Technical Field

The invention relates to the technical field of paper processing equipment, in particular to a paperboard processing structure of an creasing machine and the creasing machine.

Background

In the post-processing industry of paper, when post-printing equipment such as a laminating machine, an indenting machine, a gluing machine and the like works, when paper enters a device of the next processing procedure from a paper feeding device, the head of the paper is often warped, and especially the problem that the paper coated with the film is easier to warp is solved. The head of the paper is upwarped, so that the front end of the paper is easy to push against the paper feeding side of the next processing procedure device, and the paper is conveyed forwards continuously, so that the paper is stacked between the next processing procedure device and the paper feeding device, and the phenomenon of paper jamming is caused. The paper jam phenomenon seriously affects the normal use of the post-printing equipment.

Among the prior art, all can set up in the indentator and prevent the card paper structure, avoid the paper to pile up the card paper, prevent that the card paper structure generally all installs the front end at upper and lower cutting die in addition, the paper is carried by paper feed device and can be earlier through preventing that card paper structure department eliminates the problem that the paper head upwarps, then gets into stamping forming between the upper and lower cutting die again. But prevent the problem that the card paper structure can only eliminate the slight upwarp of paper head, if the upwarp of paper head is serious, then the paper front end probably can push up on preventing the card paper structure and cause the card paper phenomenon, leads to the indentator can not normally work, must take out the paper that is blocked. Because often compact structure between indentation unit and the output of paper feed unit, the clearance is minimum, the people hand can not stretch into, all paper that will clear up to be blocked just must pull down the anti-card paper structure, will pull down among the prior art and prevent card paper structure just must pull down cutting die, sword beam and whole blade holder, still can receive the influence of the sensor mounted position in the indentation unit, still need consider the high accuracy of aiming at of upper and lower cutting die when reinstalling, it is loaded down with trivial details inconvenient to operate.
