Description

Technical Field

[0001] The utility model relates to the technical field of cotton cleaning machines, in particular to a cleaning mechanism of a cotton cleaning machine used for the production of regenerated cotton yarn. Background Art

[0002] Cotton yarn is a textile used for weaving, rope making, thread making, knitting and embroidery, etc. Cotton yarn is made from cotton fibers through a spinning process, and is called cotton thread after being twisted. Regenerated cotton is usually used in the production of regenerated cotton yarn, that is, waste clothing fabrics are collected, and regenerated cotton yarn is obtained through the steps of crushing, combing, drawing and spinning. After the crushing process, impurities are often mixed in it, but now the subsequent steps such as combing are often carried out directly after the crushing process, so it is necessary to carry out a cotton cleaning process to remove the impurities in it. After such treatment, the regenerated cotton yarn produced is often of higher quality.

[0003] However, unlike conventional cotton blowing, which processes cotton, the production of regenerated cotton yarn processes the raw materials after the waste cloth is crushed. The impurities in the raw materials include large particles and small particles of dust, and the conventional cotton blowing machine has poor processing effect.

[0004] This case was created to solve the above problems. Utility Model Content
