Glue-free continuous printing machine

Abstract

A glue-free continuous printing machine comprises table-board rubber (1), below which a vacuum cavity (4) is arranged. The vacuum cavity (4) is connected with a vacuum generator through a hose (6). Inside the table-board rubber (1), a vacuum pipe (2) is arranged at a position corresponding to the vacuum cavity (6). In the surface of the table-board rubber (1), an air suction opening is arranged at a position corresponding to the vacuum pipe (2). With the glue-free continuous printing machine, vacuum is produced by the vacuum generation device to form negative pressure inside the vacuum cavity (4) and the vacuum pipe (2), so that the textiles to be printed and dyed are firmly absorbed to the table-board rubber without coating glue. After printing and dyeing, vacuum supply is simply stopped, and textiles can be separated. The glue-free continuous printing machine is simple and convenient in operation, pollution-free and capable of continuous production.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing machinery, in particular to a glueless continuous printing machine. Background technique [0002] In industries related to the textile and printing and dyeing industries, continuous printing machines are often used for printing processes. When using a continuous printing machine to print textiles, it is necessary to fix the cloth on the table rubber of the printing machine. Generally in the prior art, weaving is temporarily firmly adhered to the rubber of the printing machine with patch glue. However, this method is cumbersome to operate and the cost is high. After the printing and dyeing is completed, it is troublesome to separate the textile from the rubber. And this kind of patch glue is generally made of PVA (polyvinyl alcohol), and the BOD (biochemical oxygen demand) and COD (chemical oxygen demand) values ​​of PVA are very high, and it is difficult to biodegrade, causin...

AI Technical Summary

Problems solved by technology

However, this method is cumbersome to operate and the cost is high. After the printing and dyeing is completed, it is troublesome to separate the textile from the rubber.

And this kind of patch glue is generally made of PVA (polyvinyl alcohol), and the BOD (biochemical oxygen demand) and COD (chemical oxygen demand) values ​​of PVA are very high, and it is difficult to biodegrade, causing water pollution, etc.

In addition, since the prior art is glued, at least two printing screens are required to use optical screens, which cannot be used for printing and dyeing operations, but are used to press the textiles on the table rubber, wasting work space and low production efficiency.
