Problems solved by technology

However, this L-shaped or C-shaped paper feeding channel cannot feed paper from the front, and has certain restrictions on the softness of the printing medium. For thicker printing media, it will fail to feed paper or fail to feed paper, which will easily cause paper jams. phenomenon, the wear and tear on the relevant parts of the printer is also serious, shortening the service life of the printer, and the structure is complex and takes up space

Embodiment 1

[0030] see image 3 , Figure 3A and Figure 4 , an inkjet printing device of the present invention includes a frame composed of a bottom shell 1, a rear wall panel 2, a left wall panel 3, a right wall panel 4, and an upper shell. For clarity, the upper shell and other parts have been changed from Hidden in the picture. A power supply board 30 and a main board 31 are provided on the back side of the rear wall board 2, and a main control chip is provided on the main board 31 to control the operation of the entire inkjet printing equipment. Such as image 3 and Figure 4 As shown, the rear wall panel 2 , the left wall panel 3 and the right wall panel 4 are vertically arranged on the rear side, the left side and the right side of the bottom case 1 respectively. The rear wall panel 2 is provided with a movable inkjet unit, the inkjet unit includes an ink cartridge 5 and a carriage 6, wherein the carriage 6 is installed on the slide rail 7 of the rear wallboard 2, and the carr...

Embodiment 2

[0043] Such as Figure 8 As shown, the structure of the inkjet printing device of this embodiment is basically the same as that of Embodiment 1, the only difference is that there is only one sensor 29 connected to the main control chip on the axial side of the first paper guide roller 20 . The sensor 29 can simultaneously detect the presence or absence of the printing medium and the front / end position of the printing medium. Compared with Embodiment 1, this embodiment can achieve the purpose of cost saving.

[0044] This embodiment also has two working modes:

[0045] 1. Method 1: print while unloading the paper

[0046] The printing medium is put in from the paper inlet 13 and pushed onto the first paper guide roller 20 → the sensor 29 detects the existence of the printing medium and sends out a signal → the main control chip receives the signal and sends out an instruction, and the paper feeding motor 14 drives the first A paper guide roller 20 and the first friction whee...

Abstract

The invention discloses front-in front-out ink-jet printing equipment which comprises a framework, an ink jetting unit provided with a printing head, a paper feeding channel and a paper feeding mechanism, wherein the ink jetting unit comprises an ink box containing rapidly-dried ink; the paper feeding channel is a horizontal channel capable of enabling a printing medium to move horizontally; and a paper inlet and a paper outlet of the paper feeding channel are the same opening at the front side of the paper feeding channel. According to the ink-jet printing equipment disclosed by the invention, the adopted paper feeding channel is horizontally linear, the printing medium is fed in and discharged out from the front, the operation is humanized, and the requirement on the softness of the printing medium is reduced; and the rapidly-dried ink is adopted for printing, so that the rapidly-dried ink, which is jetted out by the printing head and attached to the printing medium, is solidified and dried before arriving at a friction wheel of the paper feeding mechanism, and the problem that image distortion is caused due to the condition that the friction wheel scrapes ink marks which are not dried is solved. The equipment structure is simplified; and the front-in front-out ink-jet printing equipment is convenient to install, simple in operation, low in cost, long in service life and especially suitable for front-in front-out printing media such as invoices.

Description

technical field [0001] The invention relates to an inkjet printing device, in particular to an inkjet printing device capable of realizing printing medium forward and forward. Background technique [0002] Traditional inkjet printers have little friction due to the small contact area between the star wheel and the printing medium. If the star wheel is used to feed the paper under the nozzle for printing, the printing accuracy cannot be guaranteed; and if the star wheel is replaced with a If the printing medium has a friction wheel with a large contact area, when the paper is discharged, it will cause the friction wheel to scratch the ink that has not dried up, distorting the image, and at the same time, the ink that sticks to the friction wheel will also stain the paper that passes behind. [0003] For this reason, the paper feed channel on the traditional inkjet printer is designed as L-shaped or C-shaped, such as figure 1 and figure 2 As shown, the printing medium 1A ...
