Multi-roller extrusion type cloth dewatering device for cloth printing and dyeing

Abstract

The invention discloses a multi-roller extrusion type cloth dewatering device for cloth printing and dyeing. The device comprises a torsion rolling preliminary dewatering unit and a roller extrusion dewatering unit. The torsion rolling preliminary dewatering unit is fixedly mounted on the roller extrusion dewatering unit; after cloth passes through a straight-through barrel, unwound cloth is wound together in a columnar shape and passes through the straight-through barrel; and when the columnar cloth is pulled out of the straight-through barrel, transverse pull force is matched with an inner spiral grooved rail formed in the inner wall of the straight-through barrel to drive the straight-through barrel to rotate, and the rotating straight-through barrel twists the cloth at the rear end together in a columnar shape and conveys the cloth into a box-type primary rolling dewatering assembly for dewatering treatment, so that the cloth can be twisted to be of a columnar structure before being conveyed into a dewatering structure, the later rolling water squeezing operation is facilitated, and compared with traditional cloth expansion type rolling water squeezing operation, the dewatering effect is better.

Description

technical field [0001] The invention relates to the technical field of production and processing equipment for printing and dyeing cloth, in particular to a multi-roller extrusion type cloth dehydration device for cloth printing and dyeing. 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. [0003] In the existing printing and dyeing process, it is necessary to clean the cloth before printing and dyeing to ensure that the cloth is clean and convenient for printing and dyeing. The cleaned cloth needs to be dehydrated. Most of the existing dehydration devices are centrifugal dehydration. The dehydration time is limited, and the dehydration time is long. At the same time, the drum will generate noise during the swinging process. However, the current roller extrusion dehydration device cannot twist the cloth together and enter the roller bod...

AI Technical Summary

Problems solved by technology

[0003] In the existing printing and dyeing process, it is necessary to clean the cloth before printing and dyeing to ensure that the cloth is clean and convenient for printing and dyeing. The cleaned cloth needs to be dehydrated. Most of the existing dehydration devices are centrifugal dehydration. The dehydration time is limited, and the dehydration time is long. At the same time, the drum will generate noise during the swinging process. However, the current roller extrusion dehydration device cannot twist the cloth together and enter the roller body in a columnar shape during extrusion dehydration. If the fabric is stretched into the roller body for extrusion dehydration, the dehydration effect will be poor, and the moisture in the fabric cannot be squeezed out well.
