Full-width vacuum water suctioning device for knitting

Abstract

The invention discloses a full-width vacuum water suctioning device for knitting. The full-width vacuum water suctioning device comprises a box body, wherein the box body is internally provided with a vacuum water suctioning cavity and a balanced extrusion cavity; the vacuum water suctioning cavity is internally provided with a vacuum water suctioning mechanism; first sliding grooves are arranged in the top surface and the bottom surface of the vacuum water suctioning cavity in parallel; the vacuum water suctioning mechanism is movably connected between the first sliding grooves; the balanced extrusion cavity is internally provided with traction rollers which are distributed in an S shape; a dragging mechanism is arranged between the upper traction roller and the lower traction roller; a supporting plate is arranged at the bottom part of the box body. The full-width vacuum water suctioning device disclosed by the invention has the advantages that the structure is simple, and the practicability is strong; by adoption of the vacuum water suctioning device, not only can semi-finished mercerized fabrics be forcibly permeated under the negative pressure in process liquid of strong caustic soda, no permeation can be realized, coils are not damaged, alkaline-containing liquid of fewer fabrics can enter the alkaline removing procedure, so that the alkaline removing load can be reduced; when the fabric suctions water, no additional tension for the fabric can be realized, and the alkaline removing effect is good and the energy-saving effect in the following process can be easily realized.

Description

technical field [0001] The invention relates to a knitted open-width vacuum water absorbing device. Background technique [0002] Knitting open-width mercerizing machine is a device for cotton yarn and cotton fabric to be treated with concentrated caustic soda solution and washed with water to remove alkali under certain tension conditions. [0003] At present, the vacuum suction head at home and abroad will generate additional tension on the fabric, especially the needle loop fabric, which will deform the coil. The dehydration of the high-pressure padding machine will also make the fabric hard and the coil deformed. Therefore, continuous dyeing and finishing of knitted fabrics In the process of processing, less rolling pressure and no rolling pressure are the key. Domestic and foreign mercerizing processes generally use additives resistant to high-concentration caustic soda for mutual assistance, which not only increases production and operation costs, but also provides mo...

AI Technical Summary

Problems solved by technology

Generally, the additional tension of the conventional plate-type vacuum suction device is large, which easily causes the fabric to "bow" and the coil is deformed, so it can only be sprayed w
