Carding effect, resultant yarn index are not achieved, and textile industry is urgently to be resolved hurrily.
Invention content
The purpose of the utility model is to overcome needle cloth existing in the prior art easily embedding miscellaneous, needle tooth by grass it is miscellaneous be full of, point
Comb the defect of effect difference, and provide it is a kind of by fiber control on needle tooth top, convenient for a point comb, be discharged small miscellaneous, do not allow impurity to sink to
The miscellaneous cylinder metal needle cloth of forced-ventilated of the crown.
What the technical solution of the utility model was realized in：
A kind of miscellaneous cylinder metal needle cloth of forced-ventilated, including base portion are evenly equipped with multiple continuous teeth on base portion, and each tooth includes
Front tooth part, back of tooth portion and root portion are equipped with the crown to cross together between the front tooth part and back of tooth portion of each tooth, adjacent
Two teeth between have a horizontal connection portion, the front tooth part include the straight flange portion being connect with crown, with the round and smooth connection in straight flange portion
Arc sections, arc sections and the round and smooth connection in horizontal connection portion, the arc sections concave towards root portion, the back of tooth portion include from
Crown is justified to first rake in horizontal connection portion successively round and smooth connection, the first arc sections, the second arc sections, horizontal part, third
Arc portion, the second rake and the 4th arc sections, second arc sections and the 4th arc sections concave towards root portion, the first circular arc
Towards the direction protrusion far from root portion, the straight flange portion of the front tooth part is tilted with the first of back of tooth portion for portion and third arc sections
There is tooth angle between portion, the size of the tooth angle is 15 ° ~ 30 °, and the straight flange portion of front tooth part and the angle of vertical direction are
40°。
The vertical range of the horizontal part to crown is h1, and h1 is the ㎜ of 0.15 ㎜ ~ 0.25.
The length of the horizontal part is the ㎜ of 0.25 ㎜ ~ 0.45.
The arc diameter of first arc sections is the ㎜ of 0.1 ㎜ ~ 0.3, and the arc diameter of second arc sections is
The arc diameter of the ㎜ of 0.15 ㎜ ~ 0.4, the third arc sections are the ㎜ of 0.5 ㎜ ~ 1.0, and the arc diameter of the 4th arc sections is
0.1㎜~0.25㎜。
The angle of second rake and horizontal plane is 10 ° ~ 25 °.
The space width of two neighboring tooth is the ㎜ of 1.5 ㎜ ~ 2.0.
Total a height of 1.8 ㎜ of needle cloth.
Described with the arc sections of the round and smooth connection in straight flange portion arc diameters is the ㎜ of 0.1 ㎜ ~ 0.25.
The good effect of the utility model is：Use traditional straight working edge, crown that there is the comb of small angle in front tooth part
Tooth is managed, is combined with back of tooth streamline circular arc in carded fiber, complete style of work region point comb fiber is formed, in combing
By a large amount of single fibers and small miscellaneous control therein is mingled in the first half of needle tooth, when it being allowed to divide comb jointly with cover board, smoothly will
It is small it is miscellaneous be transferred in flat strips, be discharged with flat strips, while its streamlined back of tooth is conducive to shift, promoted yield.
