Printing surface humidifying treatment device and method capable of automatically correcting and used for paperboard printing processing

Abstract

The invention discloses a printing surface humidifying treatment device and method capable of automatically correcting for paperboard printing and processing, belongs to the technical field of paperboard printing, and aims to solve the problems that the paperboard humidifying treatment effect is affected due to the fact that the paperboard is easy to deviate when being placed on a conveying belt to be conveyed by an existing humidifying treatment device; and the problem of low efficiency of humidifying treatment by repeatedly spraying to the same place due to slow infiltration of the printing surface of the paperboard during humidifying treatment by using spray is solved. After the size of a paperboard is detected through a size detection probe, a hydraulic push rod is used for driving and adjusting the distance between guide plates in a square-shaped frame, an electric piston push rod is used for driving a correction shifting plate at the ends of the guide plates to deflect back and forth to automatically shift the paperboard into the space between the guide plates, and blowing limiting rollers on the outer walls of the guide plates are matched for limiting; during limiting, a humidification processor moves up and down to take water and drip to soak a humidification cotton pressing cover paperboard, and rapid humidification treatment of the paperboard is promoted; the paperboard humidifying device is high in paperboard humidifying treatment precision, and rapid and sufficient paperboard humidifying treatment is facilitated.

Description

technical field [0001] The present invention relates to the technical field of cardboard printing, in particular, to a device and method for humidifying a printing surface that can be automatically corrected for cardboard printing. Background technique [0002] Cardboard is also called cardboard. Thick paper sheets made of various pulps with interwoven fibers. The difference between cardboard and paper is usually distinguished by the basis weight and thickness. Generally, the basis weight is more than 250g / m2 and the thickness is greater than 0.5mm is called cardboard. m2 is considered to be paper, and a basis weight of 250g / m2 or more is considered to be cardboard). The cardboard printing is to print the desired pattern or text on the outer wall of the cardboard. [0003] Before printing the pattern on the cardboard, the printing surface is generally humidified. After the printing surface of the cardboard is wetted, it is convenient for the stable adhesion of the printin...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a printing surface humidification treatment device and method that can be automatically corrected for cardboard printing processing. It aims to solve the above-mentioned background technology. Humidify the printing surface of the cardboard, the cardboard is prone to offset on the conveyor belt, resulting in incomplete humidification of the printing surface of the cardboard, affecting the effect of the humidification treatment of the cardboard, and when using spray humidification treatment, the printing effect of the spray on the cardboard Surface wetting is slow, and it is necessary to repeatedly spray on the same part of the cardboard to ensure that the cardboard is completely humidified, which affects the efficiency of cardboard humidification.
