Description

Printing and dyeing double-side spraying structure

Technical Field

The utility model relates to a textile printing and dyeing technical field, in particular to printing and dyeing two-sided sprays structure.

Background

In textile printing and dyeing, continuous pad dyeing is an environment-friendly, energy-saving and clean textile processing technology for production and dyeing, can improve the quality of printing and dyeing products, promote energy conservation and consumption reduction, and strengthen environmental protection, so that the continuous pad dyeing processing technology is accelerated to be applied and developed when backward process equipment which has high energy consumption, high pollution and can not meet the requirements of waste water treatment is eliminated.

A dyeing process in which the textile impregnation liquor is then subjected to nip roller pressure to cause the liquor to penetrate the textile and remove the residual liquor. The textile is soaked in the dye liquor for a short time by a pad dyeing method, then is rolled by a roller, the dye liquor is squeezed into the tissue gaps of the textile, and the redundant dye liquor is removed, so that the dye is uniformly distributed on the textile. In the pad dyeing process, padding liquor is required to be uniform, and the front, rear, left, middle and right liquor carrying rates are required to be uniform and consistent, and the current ideal padder is a uniform padder.

However, when the flexible or elastic textile is rolled, the textile is soaked in the dye liquor for a short time, the dye liquor in the material tank is very easy to be unbalanced, particularly, the dye liquor near the roller is very easy to be thin, and meanwhile, the textile is in passive contact with the dye liquor, so that the dye liquor is not easy to enter the fiber of the fluffy textile, the uneven dyeing is very easy to be caused, the color difference of the textile is caused, and the product quality is reduced.

The inventor researches the structure and researches a printing and dyeing double-sided spraying structure, and can solve the technical problem of printing and dyeing color spots caused by uneven dye liquor permeation into fibers in the printing and dyeing process of flexible or elastic textiles.

Disclosure of Invention

An object of the utility model is to provide a printing and dyeing two-sided spraying structure to solve flexible or elastic textile at the printing and dyeing in-process, because of the inside uneven technical problem of the printing and dyeing color spot that causes of dye liquor infiltration fibre.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

a printing and dyeing double-sided spraying structure comprises a material cylinder, a plurality of rotary roll shafts, a roller for rolling and a dye liquor circulating component, wherein the dye liquor circulating component comprises a liquid inlet pipe, a water pump and a liquid return pipe, the liquid inlet pipe, the water pump and the liquid return pipe are sequentially connected, and the liquid inlet pipe and the liquid return pipe are both connected with the material cylinder;

a double-sided spray pipe is arranged between the last rotary roll shaft and the roll and is connected with a liquid return pipe, a plurality of spray heads are arranged on the double-sided spray pipe, and the spray heads respectively point to the upper surface and the lower surface of the textile;

the conveying angle of the textile between the last revolving roller shaft and the roller is more than 30 degrees.

Furthermore, a water retaining sheet is arranged in front of the double-sided spray pipe and the roller and is arranged on two sides of the textile in a V shape. The dye liquor extruded from the roller and with relatively low concentration is quickly returned to the material cylinder through the water retaining sheet.

Furthermore, a material returning area is arranged at the lower part of the front end of the material cylinder, and the bottom of the material returning area is connected with a liquid inlet pipe.

Furthermore, a material homogenizing barrel is arranged between the liquid inlet pipe and the water pump. Is used for adding and balancing the dye liquor, so that the concentration of the dye liquor is always kept consistent.

Further, a stirrer is arranged in the material homogenizing barrel. When the dye liquor is pumped or added, the stirring function can be achieved.

After the scheme is adopted, the utility model discloses contrast prior art has following benefit:

the dye liquor circulating component can improve the uniformity of the dye liquor in the material cylinder, and ensure the uniformity of the concentration of the dye liquor output by the double-sided spray pipe, thereby improving the printing and dyeing quality;

the dyeing liquid is sprayed to the textile from the front side and the back side of the textile through the action of the double-sided spray pipe and the spray head, so that the dyeing liquid can quickly and uniformly enter the fiber of the textile, the textile dyeing liquid is particularly suitable for flexible or elastic textiles, and the consistency of dyeing colors is improved;

when the conveying angle of the textile between the last rotary roll shaft and the roller is larger than 30 degrees, the discharge of the dye liquor at the roller can be accelerated, and the dye liquor with relatively low concentration is prevented from accumulating at the front end of the press roller, so that the printing and dyeing quality is influenced.
