Description
Technical field
The present invention relates to technical field of textile machine, and in particular to a kind of doffer's needle cloth used on carding machine passes through
When twill is arranged in needle tooth side, and doffer rotates, the requirement of the angular compliance technical process of twill reaches point comb fiber well
Effect.
Background technology
The cotton (fiber) that preceding working procedure is sent is rolled up or is supplied by hopper for processing cotton fiber and chemical fibre by carding machine
Cotton (chemical fibre) layer carry out shredding point comb and removal of impurities, make all to become the single fiber shape stretched substantially in crimping block-like cotton-wool.
Doffer is component part important in its carding process, and doffer's needle cloth is the core carding element suitable of doffer workspace, and fiber exists
Cylinder-cover board master point comb can be transferred to doffer's needle cloth surface after distinguishing comb well, then be carried and be transferred to pattern doffing roller workspace.
According to process requirements, doffer's needle cloth need to have following performance indicator：(1), in cylinder-doffer trigonum, doffer's needle cloth must be able to
Enough high-speed flows effectively dredged cylinder rotation and generated, point fiber combed should be transferred to the table of doffer's needle cloth completely as possible
Face should not again return to Bearded-needle knitted cloth surface；(2) doffer's needle cloth should have suitable purchase capabilities and control to fiber
Ability should avoid doffer's needle cloth from being caught phenomenon that is, in transfer process；(3), the purchase capabilities of doffer's needle cloth should
Appropriateness cannot be too strong, to ensure in doffer-pattern doffing roller trigonum, can fiber 100% be swimmingly completely transferred to stripping
Roller.Transverse stripe doffer card clothing is one of more extensive needle cloth of existing application, and needle tooth one side is inclined-plane, is equipped with band,
Another side is smooth vertical plane, and distance of the top twill apart from needle tooth crest is 0.08mm or so.Transverse stripe doffer card clothing
In use, there are following problems：(1), the superficial velocity of doffer is the 1/15~1/30 of cylinder, doffer and cylinder it
Between the airflow that is formed Fiber Straightness, the depth of parallelism, separating degree can be caused to be deteriorated；(2), under cylinder-doffer's gauge point
Side, the air-flow that the high rotating speed of cylinder generates so that cylinder can be again returned to by being partly transferred to the fiber on doffer's needle cloth surface layer
Surface；(3), in the bottom of doffer, band can not effectively improve purchase capabilities of doffer's needle cloth to fiber, can cause to be caught
Phenomenon；(4), in doffer-pattern doffing roller workspace, doffer's needle cloth adds the design of band, can be hindered while improving purchase capabilities
Pattern doffing roller strips fiber.Based on this, the present invention devises a kind of doffer's needle cloth, and twill thereon is adjusted according to process requirements
The angle of twill achievees the effect that good fiber point comb.
Invention content
The purpose of the present invention is to provide a kind of unequal twill doffer needle cloth, i.e., in common straight tooth-shaped, arc-shaped gear doffer
The side of needle cloth added with twill, can effective solution existing doffer's needle measuring fiber degree of stretching, the depth of parallelism and separating degree it is bad,
There are problems that being caught, return phenomena such as colored.
To achieve the goals above, unequal twill doffer needle cloth of the present invention, including base portion and it is evenly distributed on base
Needle tooth in portion is equipped at least two raised or sunken twills, twill and base portion bottom surface angle theta=45- on needle tooth inclined-plane
55°。
Further, twill thickness of the present invention is D=0.02mm-0.08mm, and twill height is H=0.02mm-
0.06mm, the distance between adjacent two twill are L=0.02mm-0.06mm, distance M=of the twill peak away from needle crest top land
0.03mm-0.05mm。
Preferably, the twill thickness that is related to of example of the present invention is D=0.05mm, twill height is H=0.04mm, adjacent two
The distance between twill is L=0.04mm, and distance M=0.04mm of the twill peak away from needle crest top land, twill quantity is 2-3
Item.
Compared with prior art, the invention has the advantages that：(1) compared with band, by twill on needle tooth
Position adjusts upward, it is ensured that the grasp force of fiber；(2) with the rotation of doffer, the angle of twill is consistent with process requirements,
It when needing to capture fiber, firmly captures, when needing to shift fiber, is conducive to crawl to fiber, point comb and in time
Transfer improves the rate of transform；(3) shape of needle tooth is imitated into carding machine stepped ramp type card clothing design, it being capable of effectively carded fiber；
(4) unequal twill production easy to process promotes and applies；(5) improve fibre migration rate, improve pattern doffing roller strip it is smooth
Degree improves web quality and final resultant yarn index.

Specific implementation mode
Technical solution of the present invention is further described with reference to specific embodiment.
Embodiment 1：
As shown in Figure 1, unequal twill doffer's needle cloth that the present embodiment is related to, including base portion 1 and it is evenly distributed on base portion 1
Needle tooth 2, at least two raised or sunken twills 3, twill 3 and base portion bottom surface angle theta=45- are equipped on 2 inclined-plane of needle tooth
55°。
Further, the twill thickness that the present embodiment is related to is D=0.02mm-0.08mm, and twill height is H=
0.02mm-0.06mm, the distance between adjacent two twill be L=0.02mm-0.06mm, twill peak away from needle crest top land away from
From M=0.03mm-0.05mm.
Preferably, the twill thickness that is related to of the present embodiment is D=0.05mm, twill height is H=0.04mm, adjacent two
The distance between twill is L=0.04mm, and distance M=0.04mm of the twill peak away from needle crest top land, twill quantity is 2-3
Item.
Further, the needlepoint form for the needle tooth that the present embodiment is related to is imitated step-like.
In use, in cylinder-doffer trigonum, the twill design of doffer's needle cloth side can effectively dredge cylinder-road
The air-flow of husband trigonum reduces fiber because of gas conducive to impurity can be effectively prevent to be filled on needle cloth surface while fibre migration
Stream has some setbacks and tangled, improves the degree of orientation, the depth of parallelism and degree of stretching of fiber；Below doffer and cylinder gauge point,
The inclined direction of twill is consistent with the existing inclined direction of doffer's needle cloth operating angle, and the inclined direction of twill can effectively prevent fiber
Cylinder surface is returned to, while after position of the twill on needle tooth is adjusted to tooth top, twill can capture fiber, avoid fiber again
Secondary return cylinder surface；When using band needle cloth, lose parallel with horizontal plane of band on the needle cloth of doffer bottom grabs fiber
Holding force, when using twill, twill still has certain angle with horizontal plane, strengthens the curable grip to fiber, avoids feelings of being caught
The generation of condition；In doffer-pattern doffing roller trigonum, the direction of twill strips convenient for pattern doffing roller, reduces because stripping the generation that has some setbacks
The problems such as fault, cotton knot, effectively raises web quality and final resultant yarn index.The unequal twill doffer needle cloth effectively carries
The high rate of transform, improves the smooth degree that pattern doffing roller strips, improves web quality and final resultant yarn index.
