Description
Technical field
The utility model belongs to spinning equipment field, is related to a kind of pin cloth of Opening Roller in Rotor Spinning, more particularly to a kind of
Revolving cup spinning spins the opening roller of cotton noils.
Background technology
During rotor spinning, combing roller be single fiber and despumation are resolved into strip combing, fiber circulation is moved on to it is defeated
The primary element of gland passage.Thus, say that its quality such as bar to resultant yarn makes a good job of the number of impurity in bad, sliver in a sense
Play material impact.Usually require that the crown of combing roller tooth bar answers bright and clean sharp, and have hardness and appropriate tooth form higher
And operating angle, so in order to be pierced into the depths of sliver, be conducive to point comb, shredding and the despumation of cotton fiber, and also have
Beneficial to the release and transfer of cotton fiber.Yarn quality can both be ensured in this case, its service life can be extended again.
During cotton spinning, the strip produced by carding machine has more defect in quality, containing more short such as in strip
Fiber, impurity and fault, the extended parallelization of fiber are also poor.These defects can influence after road processing, yarn quality and resultant yarn
Fineness.Combing refer to just when fiber must Cong Yiduan be held when, the other end be subject in combing, therefore combing to fine impurities and
The exclusion of chopped fiber, to stretch fiber be very effective.Strip is by combing process under combing when cotton noils refers to cotton spinning
Come containing the short fine and more raw material of impurity.
At present, the specification of combing roller tooth bar, model are relatively more, and general its operating angle is between 65 °~100 °, and tooth is high 3
~4mm, tooth pitch is in 2~5mm.In general, the operating angle of combing roller tooth bar is bigger, and tooth is higher, tooth is close bigger, to the comb of fiber
Reason ability is stronger, but damage simultaneously to fiber is more serious.It is impure more because the length of fiber in cotton noils is shorter,
When therefore carrying out rotor spinning using it, should select less to fibre damage, and be difficult to accumulate miscellaneous combing roller model.
