Description

Technical Field

[0001] The utility model relates to the field of textile napping, in particular to an anti-winding dust removal napping roller. Background Art

[0002] The raising roller is an important part in the napping process. It contacts, destroys and lifts the surface of the textile through the napping needle, so that the surface of the textile presents different shapes and appearances. It is widely used in the textile field. However, due to the relatively violent contact between the needle and the surface of the textile, the thread ends are easily broken and entangled, which seriously affects the service life and napping effect of the raising roller. The operator needs to clean it regularly. At the same time, a large amount of dust will be generated during the napping operation. In addition to affecting the environmental quality of the workshop, excessive dust will also affect the placement of equipment and need to be cleaned in time. Therefore, the existing napping equipment will be specially equipped with a dust removal device; for example, the application number 202021196583.7 discloses a waste hair collection system for a napping machine, which can solve the dust problem by sucking dust and thread ends from the napping cavity and the bottom of the cavity through a suction fan, but the dust removal efficiency is low and the compatibility with the napping roller is not high. Therefore, there is an urgent need for a napping roller that is anti-entanglement and has high dust removal efficiency. Utility Model Content
