Description

TECHNICAL FIELD

[0001] The present application relates to the field of textile dyeing devices, in particular to a dyeing tube with anti-blocking function. BACKGROUND

[0002] The dyeing tube is one of the important tools in the yarn dyeing process. When in use, the yarn to be dyed is wound on the dyeing tube, and then the dyeing tube is put into the dyeing cylinder. The dyeing liquid flowing in the dyeing cylinder penetrates into the yarn from all directions. Generally, a plurality of through holes are arranged on the wall of the dyeing tube. The flowing dyeing liquid can enter the inside of the dyeing tube and flow out from the through holes to dye the yarn from the inside, thereby improving the uniformity of the yarn dyeing.

[0003] The conventional dyeing tube is a hollow stainless steel or plastic tube. A plurality of through holes are arranged on the outer wall of the tube. This type of dyeing tube is simple to manufacture and low in cost. However, the following problems exist in the use of the dyeing tube.

[0004] 1. Non-uniform dyeing: The uniformity of yarn dyeing has high requirements on the winding thickness and density of the yarn. With the increase of the winding thickness of the yarn on the dyeing tube, it is more and more difficult for the dyeing liquid to penetrate into the inside of the yarn for dyeing. Therefore, it is necessary to increase the dyeing time or adjust the winding thickness and density to ensure the uniformity of the dyeing of the inside yarn, which reduces the dyeing work efficiency and increases the operation difficulty.

[0005] 2. After the dyeing time is reached, the yarn and the dyeing tube are dried and the yarn is unwound. During the drying, the dyeing liquid remaining on the inner wall of the dyeing tube is solidified and adhered after being dried. If the through holes are not cleaned for a long time, the through holes will be blocked, which will affect the subsequent use. In order to clean the dyeing tube, after the yarn is unwound, the dyeing tube is collected and the inner wall of the dyeing tube is cleaned by using a brush, a cleaning ball or other tools. This process is time-consuming and labor-intensive, which greatly affects the production efficiency and increases the labor intensity. SUMMARY

[0006] The dyeing tube with anti-blocking function is provided to solve the problems of non-uniform dyeing and inconvenient cleaning of the dyeing tube in the background technology.

[0007] The embodiment of the application provides a kind of anti-blocking dyeing pipe, including hollow pipe, it is characterized in that: the cleaning device is arranged in the hollow pipe, one end of the cleaning device is connected with front baffle ring, the other end of the cleaning device is equipped with rear baffle ring, the front baffle ring top is equipped with inlet pipe, the inlet pipe top is equipped with front bearing and front sealing device, the inlet pipe end is equipped with adjusting block and connector, the connector is connected with conversion head by pipeline, the conversion head is connected with first electromagnetic valve and second electromagnetic valve by pipeline, the other end of the rear baffle ring is equipped with support shaft, the support shaft is equipped with rear bearing and rear sealing device, one end of the hollow pipe is equipped with front end cover, the other end of the hollow pipe is equipped with rear end cover, the hollow pipe is equipped with through-hole, and the cleaning device includes cleaning block and support block.

[0013] The technical scheme provided by the embodiment of the application has at least the following technical effects or advantages:

[0014] 1. The cleaning device, bearing, adjusting block and the like are arranged in the hollow pipe, after the yarn on the hollow pipe is dyed, the cleaning device is rotated by rotating the adjusting block before drying, the cleaning block on the cleaning device removes the residual dyeing liquid on the inner wall of the hollow pipe, the removed dyeing liquid is discharged from the through-hole and the inlet pipe, and the dyeing liquid remaining on the inner wall of the hollow pipe is prevented from drying and solidifying. After the yarn is unwound after the hollow pipe is dried after being cleaned by the cleaning device, the hollow pipe can be used to wind the yarn for the next dyeing work, and the work efficiency of dyeing is improved.
