Problems solved by technology

[0004] In the prior art, the inkjet printing machines used in the assembly line mostly use conveyor belts to transport the printing material paper. The reverse side is printed at the same time; the platform-type paper transfer mechanism takes up a lot of space and requires high technology; the inkjet paper feeding method of the platform-type inkjet printing is easy to make the paper dirty or even damaged; High precision requirements and insufficient flatness will cause the distance between the nozzle group and the flat plate to be unable to be fixed, resulting in inaccurate printing and other problems

Abstract

The invention discloses a two-sided ink-jet printer, comprising a paper supply unit, a printing unit, and a paper collection unit. The paper supply unit comprises a paper feed mechanism and a paper feed roller, and is used to transmit paper to the printing unit to print. The printing unit comprises a front-surface printing roller, a paper transport unit, a back-surface printing roller, an ink jet head, and a drying device. The paper transport unit is arranged below the front-surface printing roller and the back-surface printing roller. The paper transport unit comprises a plurality of paper transport rollers. The paper transport rollers are used to transmit the paper which has been printed on the front surfaces to the back-surface printing roller to print on the back surfaces. The paper collection unit comprises a paper collection roller, a paper collection component, and a transmission portion. The paper collection roller is one a side of the back-surface printing roller, close to the front-surface printing roller. The paper collection roller transmits the paper which completes two-sided printing to the paper collection component. The printer is simple in structure, low in cost, small in space occupation, and accurate in printing, and the printer can protect paper.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to a double-sided inkjet printing machine. Background technique [0002] With the rapid development of social informatization and networking and the continuous progress of printing technology, digital inkjet printing has also made great progress, and the printing quality has continued to improve, which will gradually replace traditional lithographic offset printing technology. Inkjet printing is the process of jetting ink droplets to the substrate to form an image. Due to its characteristics of no plate, no pressure and digital imaging, it is showing an extremely strong development momentum in today's digital world, with on-demand printing, high-speed , high quality, low price, wide color and other advantages; in addition, the inkjet printing machine is a kind of "non-contact with the object" inkjet printing high-tech digital printing equipment, because the inkjet printin...
