Efficient supercharged cotton yarn environment-friendly dyeing device

Abstract

The invention discloses an efficient supercharged cotton yarn environment-friendly dyeing device, and belongs to the field of yarn processing equipment, the efficient supercharged cotton yarn environment-friendly dyeing device comprises a yarn dyeing machine, a yarn coiling and dyeing assembly, a water pressure pressurizer and a filter screen wall scraping assembly, one end of the upper winding roller and one end of the lower winding roller are fixedly sleeved with a first-stage belt, liquid spraying holes are formed in the surface of the winding base at equal intervals, a water outlet pipe and a water suction pipe are fixedly connected to the bottom end of the water pressing shell, and the water outlet pipe leads to the interior of the winding base and communicates with the liquid spraying holes; the secondary motor is fixedly installed at one end of the upper surface of the circulating liquid box, a traditional dyeing mode of spraying dye liquor is changed, the dyeing time is shortened, meanwhile, the dyeing effect is guaranteed through a mode of mechanically increasing water pressure, additional electric supercharging equipment is not needed, in addition, charging and discharging are convenient, and the cost is reduced. And manual cleaning of the filter screen can be replaced.

Description

technical field [0001] The invention relates to the field of yarn processing equipment, and more particularly, to a high-efficiency pressurized type environmental protection dyeing device for cotton yarn. Background technique [0002] Yarn dyeing, a dyeing process for yarn. Mainly include: "beam dyeing", "hank dyeing", "cheese dyeing", "compressed cheese dyeing" and "filling dyeing", etc. The above are uniform dyeing processes, and "spaced dyeing" is also yarn dyeing; Among them, hank dyeing: it is the dyeing in which the fiber yarn is hung in a skein in a special dyeing machine, and the dyeing liquid is circulated or stirred by a pump or a mechanical device to obtain a level dyeing; [0003] However, the existing hank dyeing machines have the following defects: [0004] (1) The dyeing method of the existing hank dyeing machine usually adopts the method of spraying the dyeing agent for dyeing. In this method, the contact between the yarn and the dyeing agent needs to reach...

Problems solved by technology

[0004] (1) The dyeing method of the existing skein dyeing machine usually adopts the method of spraying the dyeing agent for dyeing. In this way, the contact between the yarn and the dyeing agent needs to reach a certain period of time before a good dyeing effect can be guaranteed. , the dyeing time is too long, the production efficiency is low, and the working time is too short, it is easy to cause insufficient contact between the yarn and the dyeing agent, and the dyeing effect is not good;

[0005] (2) In the work of dye liquor circulation, it is usually necessary to remove impurities from the dye liquor before putting it into use again. However, in this process, the surface of the filter screen is easily blocked by a large amount of wool after long-term use , which in turn affects the filtering effect of the dye liquor. At the same time, the work of manually repairing the filter screen is too complicated and time-consuming
