Quantitative cloth printing and dyeing equipment

Technical Field

The invention belongs to the technical field of textile printing and dyeing, and particularly relates to quantitative cloth printing and dyeing equipment.

Background

Exhaust dyeing is also known as exhaust dyeing. Dyes are the term applied. The method comprises immersing the object to be dyed in a dye bath containing the dye and the required auxiliary agent, and gradually dyeing the object to be dyed by the dye bath circulation or the movement of the object to be dyed. At present to the dip-dyeing technology of cloth, one of them is for directly putting into the dye liquor that has the uniform temperature with the whole scattering of cloth in the middle of, then through modes such as stirring the cloth, make the absorption dyestuff that the cloth can be abundant, the method of this dyeing has the advantage that the cloth is colored evenly at the in-process of dyeing, consequently, the cloth quality of dyeing out is high, but because the in-process cloth that dyes in the dip-dyeing receives the stirring of external force etc. a large amount of folds can appear in originally smooth cloth, lead to the cloth to need carry out many times flattening in the later stage, it can influence the quality of cloth.

The other dip dyeing process is that a cloth passing roller is arranged in a dyeing tank, and then cloth quickly passes through the cloth passing roller; for example, chinese patent CN107988747A discloses a high-efficient dyeing machine is used in weaving, including the main engine body, the top of the main engine body is provided with flexible motor, the bottom of flexible motor is provided with flexible arm, flexible motor is connected with flexible arm transmission, the bottom of flexible arm is provided with the printing roller, the printing roller rotates with flexible arm and is connected, the both sides of the main engine body are provided with the support, the bottom of support is provided with the support column, driving motor is installed to the one end of support column, support column upper portion is provided with a pair of live-rollers, be provided with the transfer line between support column and the live-rollers, the transmission is connected between transfer line and the driving motor, be provided with the dye cell under the main engine body, the bottom in dye cell is provided with a pair of pulley, the left and right sides of pulley all is provided with.

In the above document, by arranging the rotating roller, the cloth passes through the rotating roller, and in the process, because the rotating roller is located in the dye liquor, the cloth can be partially in the dye liquor when passing through, so that the continuous dip dyeing of the cloth is realized.

Disclosure of Invention

The invention provides quantitative cloth printing and dyeing equipment which has the advantages of good printing and dyeing effect, flat cloth and simple structure, and overcomes the defects of the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: a quantitative cloth printing and dyeing apparatus comprises

A dye vat containing dye liquor;

the cover plate is in sealing fit with the dye vat;

a vacuum pumping device for pumping out the gas in the dye vat;

the cloth rolling device is used for rolling the cloth and immersing the cloth in the dye liquor;

and the driving device is used for driving the cloth rolling device to roll the cloth back and forth in the dye liquor.

According to the invention, the cloth is wound together in advance by arranging the cloth winding device, then the whole cloth is directly immersed into the dye liquor together with the cloth winding device, and the dye liquor can gradually permeate into the wound cloth in the process, so that the pre-dyeing of the cloth is realized, and the dyeing rate of the cloth is improved; under the drive of a subsequent driving device, the cloth is rewound in the dye liquor, the distributed cloth is spread out in the middle of the rewinding process, so that the cloth is fully contacted with the dye liquor, the dye in the dye liquor can be fully colored on the cloth, and the cloth is fully colored in the process; in addition, the cloth can be rewound back and forth for multiple times with different times according to the cloth made of different materials, so that the cloth is fully dyed; in the dyeing process, the cloth moves in the dye vat, the movement enables the cloth and the dye liquor to form convection, the convection improves the efficiency of the dye on the cloth, and further improves the dyeing efficiency.
