Problems solved by technology

[0002] In the inkjet printing process of textiles, a program-controlled inkjet printing machine must be used, but the existing inkjet print head has the following defects in the printing process: (1) Most of the existing inkjet printing uses pigment ink, which is comparable to dye ink. Compared with the poor stability of pigment ink, the combination of pigment ink and textiles, especially cotton fabric, is not very good. In order to improve and enhance the stability of pigment ink, the binding force and color fastness with cotton fabric, pigment ink Various additives are added, which improve and enhance the relative performance of pigment inks, but cause the problem that the inkjet print head is easy to clog
Especially when printing intermittently, the inkjet print head is easy to clog
This not only affects the speed of inkjet printing, prolongs the production cycle, increases production costs, but also seriously affects the quality of inkjet printing
(2) The caliber of the inkjet port of the existing inkjet print head is fixed, and the size cannot be adjusted and changed
The inkjet flow rate of the existing inkjet print head is not adjustable and uncontrollable, which affects the quality of inkjet printing

Abstract

The invention relates to a novel ink-jet printing head. The printing head is characterized in that an ink box, an ink jet hopper, an ink jet head, a slide bar, a crank shaft, an electromagnetic clutch and a micro motor are included, the bottom of the ink box is connected with the ink jet hopper in a funnel shape, the bottom end of the ink jet hopper is provided with the ink jet head, the middle hollow portion of the ink jet head is provided with the coaxial slide bar, the slide bar is provided with a small piston, the uppermost end of the slide bar is connected with the crank shaft, and the crank shaft is connected with an output shaft of the micro motor through the electromagnetic clutch. The novel ink-jet printing head has the advantages that the inkjet printing speed is high, flow is easy to control and the ink jet head can be prevented from being blocked.
