Printing and dyeing pretreatment device with good liquid feeding effect

Abstract

The invention relates to a printing and dyeing pretreatment device with a good liquid feeding effect, and relates to the field of printing and dyeing equipment. The printing and dyeing pretreatment device comprises a pair of supporting plates, wherein a pair of guide rollers and a pair of power rollers are rotationally connected between the pair of supporting plates, and driving pieces for drivingthe power rollers to rotate are arranged on the power rollers; a hollow liquid outlet roller is arranged between the guide rollers and the power rollers, a plurality of through holes are formed in the side face of the liquid outlet roller, rotating shafts rotationally connected with the corresponding supporting plates are fixed to the two ends of the liquid outlet roller correspondingly, and therotating shafts are of a hollow structure; one of the rotating shafts penetrates through the corresponding supporting plate and is fixedly provided with a rotating joint, and the end, far away from the corresponding supporting plate, of the rotating joint is connected with a liquid storage tank; a receiving box is arranged below the liquid outlet roller, a plurality of collecting holes are formedin the upper surface of the receiving box, the lower surface of the receiving box communicates with a water return pipe, and the end, far away from the receiving box, of the water return pipe communicates with the liquid storage tank; and gray cloth sequentially passes through the space between the pair of guide rollers, the space between the liquid outlet roller and the receiving box and the space between the pair of power rollers. The printing and dyeing pretreatment device with the good liquid feeding effect has the effect of facilitating full utilization of working liquid.

Description

technical field [0001] The present application relates to the field of printing and dyeing equipment, in particular to a printing and dyeing pretreatment device with better liquid feeding effect. Background technique [0002] Printing and dyeing, also known as dyeing and finishing, is a processing method and a general term for pretreatment, dyeing, printing, finishing, washing, etc. A large amount of textile detergents are used in the pretreatment process of textiles, and environmental protection should be used A high-quality surfactant and a new detergent preparation technology to prepare an excellent environmental protection pretreatment agent. [0003] In short-process pre-treatment, no matter it is desizing first or desizing and boiling process first, it must first be padding desizing, scouring or oxygen bleaching working fluid, and necessary additives such as penetrating agent.

AI Technical Summary

Problems solved by technology

[0003] In short-process pre-treatment, no matter it is desizing first or desizing and boiling process first, it must first be padding desizing, scouring or oxygen bleaching working fluid, and necessary additives such as penetrating agent. Traditional short-process pre-dyeing During processing, soak the gray cloth in the working solution to carry liquid, but this method of supplying liquid contains too much liquid

[0004] In view of the above-mentioned related technologies, the inventor believes that excessive liquid supply to the gray cloth is likely to cause waste of working fluid
