Ink-jet printer

Abstract

The ink-jet printer comprises a printing trolley, a driving mechanism, a printing platform, feeding mechanisms, a drying device and an air drying device, the feeding mechanisms comprise the first feeding mechanism located on the front side, the second feeding mechanism located in the middle and the third feeding mechanism located on the rear side, and the printing platform is installed above the second feeding mechanism; the driving mechanism is transversely erected above the second feeding mechanism, the printing trolley is installed on the driving mechanism, and the printing trolley is located in the area above the printing platform; the drying device is installed above the first feeding mechanism, the air drying device is installed at the bottom end of the second feeding mechanism, a discharging roller and a collecting roller are installed on the third feeding mechanism, an ink droplet diffusion area is arranged between the first feeding mechanism and the second feeding mechanism, and the distance between the first feeding mechanism and the second feeding mechanism is adjustable. The printing device has the beneficial effects of being good in printing effect, few in flaws, good in drying effect and small in pollution.

Description

technical field [0001] The invention relates to the technical field of inkjet printing equipment, in particular to an inkjet printer. Background technique [0002] The inkjet printer completes the printing of patterns or characters by ejecting ink droplets on the printing medium through the nozzle. During the printing process, the ink may be mixed with air bubbles when it flows through various components, and the air bubbles may easily lead to the empty spray of the nozzle. In order to solve this problem, in the prior art, a degassing device is usually set in the ink path before the ink enters the secondary ink cartridge, and the ink that is about to enter the secondary ink cartridge is degassed before entering the secondary ink cartridge. The degassing effect of this method is not ideal, because the ink has a certain speed when entering the secondary ink cartridge, and tiny bubbles will also be generated when it collides with the inner wall of the secondary ink cartridge a...

AI Technical Summary

Problems solved by technology

[0007] 1) The degassing effect of the ink in the prior art is not ideal, and the situation of empty spraying will also occur during printing;

[0008] 2) The oily ink droplets are not easy to dry on the surface of the medium, which will cause the paper to bulge, and the paper will scratch the nozzle, print pattern deformation, ghosting and other problems;

[0009] 3) After printing, the printing medium directly enters the drying area for drying, and the ink droplets do not have time to diffuse freely, resulting in too much white space on the printed medium, which makes the color of the pattern lighter, and even makes the defects more obvious;

[0010] 4) The paper will be deformed after ink infestation and drying, which will lead to wrinkles or irregular delivery during the delivery process;

[0011] 5) The oil mist generated during the printing process not only causes environmental pollution, but also adversely affects the health of on-site workers; the oil mist condenses on other parts and accumulates into oil droplets, which drip to the bottom surface causing environmental pollution, Dripping onto the print media renders the printed product unusable
