Printing machine for textile fabric

Abstract

The invention relates to the technical field of textile fabric processing, and discloses a printing machine for textile fabric. The printing machine comprises a spray head, spray holes are formed in the right side of the bottom of the spray head, a segmentation impeller is movably installed in the spray head, and an extrusion cavity is fixedly connected to the top of the spray head. Through the arrangement of silicon film piezoelectric ceramic elements and silica gel films, when the silicon film piezoelectric ceramic elements perform a piezoelectric effect, a piezoelectric ceramic plate is bent; when the two silicon film piezoelectric ceramic elements are both bent inwards, the ink in the middle is extruded and discharged from the spray holes, and first-time acting is performed; when the two silicon film piezoelectric ceramic elements are bent outwards, water is extruded, certain pressure is applied to the water, the water presses the silica gel films downwards, the ink is pressed again, the ink is sprayed out of the spray holes, and second-time acting on the ink is completed, so that the effective frequency of the silicon film piezoelectric ceramic elements is increased; and in addition, the printing ink spraying frequency is improved, and the printing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of textile fabric processing, in particular to a printing machine for textile fabrics. Background technique [0002] With the increase of people's personalized consumption demand, the printing demand for textiles is becoming more and more important. The traditional rotary screen printing and flat printing process are complicated and the production cost is high. Therefore, inkjet printing technology has emerged as the times require. The non-contact clean printing of textiles, its working principle is: the ink is forced to pass through a small nozzle under high pressure, the diameter is distributed in the range of 10-100um, the ink liquid flow out is divided into fine droplets, and falls on the textile , and then form the required pattern by intensive and regular jetting of ink, but there are some shortcomings in the existing inkjet technology, as follows: [0003] First, when using piezoelectric technology t...

Problems solved by technology

[0004] Second, in order to improve and enhance the stability of the pigment ink, the binding force with the cotton fabric, and the color fastness, various additives are added to the pigment ink, which improves and enhances the related performance of the pigment ink, but causes inkjet printing. The nozzle is easy to be blocked, and the nozzle needs to be disassembled for cleaning in the later stage. The process is very troublesome. Similarly, the printing machine is generally used intermittently, which makes it easy for the pigment to form deposits in the nozzle, resulting in a decline in printing quality
