Dewatering, untwisting and opening equipment for textile printing and dyeing

Abstract

The invention discloses a textile printing and dyeing dehydration and untwisting opening equipment. By changing the dehydration mode of textiles, the textiles are horizontally drawn by a tractor. The spiral untwisting and dewatering cylinder is equipped with a spiral dehydration section, a smooth buffer section and a spiral untwisting section respectively, and the textiles are rotated and extruded by using the positive spiral threads on the spiral dehydration section, so that the waste water in the textiles is quickly and completely separated , while the anti-rotation thread of the spiral untwisting section is used to reverse and untwist the textiles to eliminate the torsion of the textiles. Wrinkles generated in the dehydration process; solve the technical problem that no additional untwisting device is needed, and perfectly solve the technical problem of wrinkles in the textile during the rotary extrusion dehydration process.

Description

Technical field [0001] The invention relates to the technical field of textile dehydration, in particular to a textile printing and dyeing dehydration untwisting opening device. Background technique [0002] In modern printing and dyeing textile enterprises, the textiles printed and dyed by the printing and dyeing device contain a large amount of moisture, and the moisture contains a large amount of dyeing pigments, dye auxiliaries and other chemical raw materials. Therefore, it is necessary to remove the printing and dyeing wastewater contained in the textiles through dehydration equipment. Most of the traditional dehydration methods use centrifugal dewatering. Most of the textiles after centrifugal dewatering are twisted and become rope-like due to the centrifugal force. Therefore, the dehydrated textiles need to be untwisted before the subsequent processing procedures. Eliminate twisting, and open the textile to make the textile return to the open-width state. The traditional ...

Problems solved by technology

[0002] In modern printing and dyeing textile enterprises, the textiles printed and dyed by the printing and dyeing device contain a large amount of water, and the water contains a large amount of various chemical raw materials such as dyeing pigments and dyeing aids. Therefore, dehydration equipment is required to remove the printing and dyeing wastewater contained in the textiles. However, the traditional dehydration method mostly uses centrifugal dehydration. Most of the textiles after centrifugal dehydration are twisted and become rope-shaped due to the centrifugal force. Therefore, before the subsequent processing procedures, the dehydrated textiles need to be untwisted. Eliminate torsion, and open the textile to return the textile to the open state. The traditional untwisting method is to use an untwisting device to untwist after the textile is dehydrated. An additional untwisting step is added, which is too cumbersome

[0003] In the Chinese patent whose patent number is CN104528450B, a kind of open-width centering machine is disclosed, which is to advance and untwist the textiles after centrifugal dehydration by setting an untwisting device at a high place, and use a spreading mechanism to open the textiles after untwisting. Spread out, very cumbersome
