Paperboard printing device

Abstract

The invention relates to a printing device, in particular to a paperboard printing device. The paperboard printing device comprises a supporting frame, a control screen, a first motor, a first transmission wheel, a liquefaction mechanism, an automatic adding mechanism, a dust removing mechanism, a flattening mechanism, a flow regulator, a liquid delivery pipe, a printing mechanism and a storage bin; and the control screen is arranged on the middle-top part of the left end of the supporting frame, and the first motor is arranged on the middle-left part of the bottom end in the supporting frame.The paperboard printing device achieves the effects that industrial alcohol volatile in a fountain solution is liquefied and collected, manual contact and consequently damage to human health are avoided, meanwhile, the fountain solution required by printing can be quickly supplemented, manual feeding is replaced with automatic feeding through a machine, the situation that the machine idles to waste energy is avoided, and by treating dust of a paperboard and flattening the bending edge, the situation that printing patterns are unclear, the printing quality is reduced, and consequently, the quality of a finished product is poor is avoided.

Description

technical field [0001] The invention relates to a printing device, in particular to a cardboard printing device. Background technique [0002] When the cardboard printing machine is working, the text and images to be printed are first made into a printing plate, which is installed on the printing machine, and then the printing machine is operated by a person to evenly apply the ink to the text and image on the printing plate, and then directly or indirectly Transfer onto corrugated cardboard or carton, thus reproducing a printed replica identical to the printing plate. Existing printing machines generally use manual feeding, and manually pick up the cardboard after printing, which makes the workload of the operator heavy and the printing efficiency low; at the same time, due to the large amount of dust and other impurities on the cardboard, the ink will be damaged during printing. If it sticks to the dust, the dust will move or drive the ink to shift in the later stage, res...

AI Technical Summary

Problems solved by technology

[0006] The present invention overcomes the lack of cleaning of the dust on the printing surface of the cardboard in the prior art, the temperature rises in the workshop when the machine is running for a long time, the printing pattern is not clear, the printing quality decreases, and the edge of the cardboard is bent due to the excessive temperature in the workshop, causing the machine to stop. Damage to the machine, lack of treatment for the volatilization of industrial alcohol in the dampening solution, the reduction of alcohol concentration, the decline in the efficacy of the dampening solution, and the low printing quality. At the same time, the volatilization of industrial alcohol will be harmful to the human body and endanger the lives and health of workers. The technical problem to be solved by the invention is to provide a printing device for cardboard
