Problems solved by technology

The humidity of the paper itself also affects the drying of the ink, resulting in poor ink drying and smearing
If the edge of the paper turns inside out and is uneven, it means that some part of the paper roll is too loose or too tight, which is not suitable for printing

Abstract

The invention discloses a roll paper printing device which comprises a rack, a printing unit is arranged on the rack, a winding machine and an unwinding machine are arranged at the positions, located on the two sides of the printing unit, of the rack correspondingly, and elastic pressing rollers are arranged at an outlet of the unwinding machine and an inlet of the winding machine correspondingly. A pressure sensor is arranged on each elastic pressing roller, a paper clamping and conveying roller is arranged on the portion, between the unwinding machine and the printing unit, of the rack, a hot air drying device is arranged on the portion, between the winding machine and the printing unit, of the rack, and the paper clamping and conveying roller is controlled by a fixed-frequency motor. The winding machine and the unwinding machine are controlled through a first variable frequency motor and a second variable frequency motor respectively, and the pressure sensor, the fixed frequency motor, the first variable frequency motor and the second variable frequency motor are connected with a PID closed-loop controller. Printing ink is heated evenly, paper rolls are prevented from being too loose or too tight, and the printing effect is good.

Description

technical field [0001] The invention belongs to the technical field of chemical products, and in particular relates to a printing device for roll paper. Background technique [0002] The roll paper is made of paper made by a paper machine, cut into a roll by a rewinding machine, and meets the required width and diameter. Web offset presses are favored by many printing companies for their high efficiency, strong adaptability to printing books and newspapers, and good economic benefits. However, in printing, the product quality is often affected by the problem of dragging. [0003] Smearing means that the imprint on the printed matter dries slowly, and part of the ink adheres to the paper guide roller, triangular plate, folding roller and conveyor belt that the paper belt passes through, and is returned to the paper, causing stripes of oil on the printed matter. Ink dirty. There are many reasons for the phenomenon of smearing. It has a lot to do with paper structure, ink co...
