Digital textile printing high-speed output equipment

Abstract

The invention relates to digital textile printing high-speed output equipment using piezo jet technology, in particular to the digital textile printing high-speed output equipment of a large pattern. A dye bucket of the equipment is fixed, dyed matters such as a cloth material and the like move at a high speed; high-speed continuous textile printing operation is formed according to unit width or required width; therefore, production efficiency can be greatly improved, the dye bucket which produces heat during the high-speed textile printing operation is forcibly cooled, and continuous high-speed textile printing can be guaranteed.

Description

technical field [0001] The present invention relates to a high-speed output device for digital printing using piezoelectric inkjet technology (piezo jet). The continuous printing operation can greatly improve the production efficiency, and at the same time, the dye tank that generates heat during the high-speed printing operation is forced to cool to ensure that the high-speed printing can continue. Background technique [0002] Generally speaking, the actual pattern output process is to use computer and related software, that is, use image editing software such as Corel DRAW, Photoshop and Illustrator to prepare the image to be printed, and then use RIP (Raster Image Processing) program to generate computer image data, and finally Output to large pattern output devices. [0003] The advantage of the above-mentioned image output method using a large-scale pattern output device is that it can output the data edited by the computer to the dyed object as it is. Compared with t...

Problems solved by technology

[0005] On the other hand, for the thermal printing (bubble inkjet method) technology used in high-speed printing, since multiple dye barrels are used to move back and forth along the width direction of the dyed object such as cloth (direction perpendicular to the direction of cloth travel), according to The method of printing in a certain interval or line by line is not only slow in printing speed, but also low in efficiency, and does not have a suitable device for cooling the dye barrel that generates heat during high-speed printing, so it is not suitable for long-term printing (or printing ), in order to solve the heat release problem of the dye tank, only intermittent operations can be carried out, which greatly reduces the production efficiency

[0006] In addition, the dye barrel adopts a reciprocating structure, so it is difficult to accurately determine the initial position of the dye injection position, so errors are prone to occur during speed control. If such errors occur, it will be due to inaccurate dye injection positions. Cause printing focus to be different, reduce quality

In addition, for the high-speed printing method that supports bidirectional printing, there will be errors in the printing position due to the separation of the connecting part, which will reduce the printing quality.

[0007] In addition, due to the smooth operation of the motor and the limitations of the injection of the spray gun, and the dye barrel is a mobile structure, the accuracy is reduced, causing the printing head to touch or wipe the dyed object, so that the printing head hangs on the dyed object. The tearing of the dyed object, if serious, will not only cause damage to the dye barrel, but also cause impurities, air bubbles, etc.
