Ink-jet apparatus

Abstract

The invention discloses an ink-jet printing device which comprises a bearing body, an ink supply groove, a plurality of inking pipes, a seat body and a pivot device, wherein the bearing body is used for bearing a print head device, and can move in the ink-jet printing device in a reciprocating way. The ink supply groove is used for providing inks needed by the print head device. Both ends of each inking pipe are respectively connected with the ink supply groove and the print head device. The pivot device is provided with a restriction part, and can be arranged on the seat body in a rotatable mode. A part of the section between the both ends of each inking pipe is fixed at the restriction part. According to the ink-jet printing device, each inking pipe can maintain enough bend curvature radius to avoid the condition that flow resistance is too large, the process of reciprocating motion of the bearing body is more smooth, and the printing quality is more stable.

Description

technical field [0001] The present invention relates to an ink jetting device, and more particularly to an ink jetting device including a hinge means for securing an ink delivery tube. Background technique [0002] refer to Figure 1A with Figure 1B , which is a schematic diagram of a printer (HP 8250) with known head water separation. As shown in the figure, the printer includes at least a carrier 11 , a print head device 12 , an ink supply tank 14 and a hose 15 . [0003] Wherein, the carrier 11 is used to carry the print head device 12 , and can move back and forth along the slideway 13 in the printer, so that the print head device 12 can perform printing work. The ink supply tank 14 is used to provide ink required by the print head device 12 . Flexible pipe 15 has replaced common four ink supply pipes 152, just utilizes flexible pipe 15 to integrate four ink supply pipes 152 together (referring to Figure 1A The enlarged schematic diagram of the section a-a' in ), an...

AI Technical Summary

Problems solved by technology

[0006] 1. Both the second fixed end and the swing bracket 18 are independent components, which cannot be effectively integrated, resulting in an increase in manufacturing and assembly costs

[0007] Two, the manufacturing cost of hose 15 is higher

When the bending radius of curvature (R) of the hose 15 changes more, the force applied by the hose 15 to the carrier 11 will be less fixed, so the carrier 11 will experience uneven force during the movement process, which will affect Movement stability and print quality

[0010] 5. Whenever the hose 15 swings as the carrier 11 moves to the right, the hose 15 will continuously beat the ink supply tank 14, which will reduce the service life of the hose 15
