Description
Technical field
The utility model is related to a kind of fibre migration pretreatment unit, specifically a kind of spinning cotton cylinder metal needle cloth.
Background technology
Cylinder metal needle cloth is important point of comb original paper of carding machine, and the specification of metallic card clothing and the combing effect of carding machine have
Close relationship.It is the key factor for determining Bearded-needle knitted cloth carding capacity that the transverse teeth of cylinder metal needle cloth is close and longitudinal tooth is close,
Lateral crown is away from smaller, and point comb power is bigger, and base thickness W originally is 1.0-0.6mm, cannot be met and present high speed high yield
The mating combing of carding machine, point comb strength is excessive to be easy to cause fibre damage and the big damage needle cloth of load, and appearance point comb is insufficient to ask
Topic.
Utility model content
To solve the problems, such as that existing Bearded-needle knitted cloth point comb poor performance and fibre damage, the utility model provide a kind of spinning cotton
Cylinder metal needle cloth.The needle cloth can reduce fibre damage, can reach strong carding role, reduce cotton knot and generate, and be conducive to improve cotton
Yarn quality.
The utility model is achieved through the following technical solutions：Cotton cylinder metal needle cloth is spun, includes the base in bandlet shape
Portion and the needle tooth being distributed on base portion, the wide b of base portion are 0.5mm, and the tooth pitch a of the needle tooth on base portion is 1.5mm, operating angle
α is 30 °.
As being further improved for technical solutions of the utility model, total high h of the base portion and needle tooth is 2.0mm, needle tooth
Tooth depth h1For 0.45mm.
As being further improved for technical solutions of the utility model, the teeth portion working face of the needle tooth is concave surface arc knot
Structure, the teeth portion back side are convex surface arcuate structure.
As being further improved for technical solutions of the utility model, wherein one side is in the teeth portion two sides of the needle tooth
Vertical plane, other side face are inclined-plane.
Compared with prior art, the thin lateral density of base portion increases the utility model, and flock is laterally resolved into single fiber effect
Fruit increases, and fibre bundle is made line to combing by tooth pitch longitudinal direction, reduces front and back existing important combing, it is ensured that comb unimpeded, reduction cotton
Knot, operating angle is small, increases the gripping to fiber, solves fiber caused by since high speed, centrifugal force are big and slips, reduces the fibre that swims
Dimension improves carding role.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram described in the utility model for spinning cotton cylinder metal needle cloth.
Fig. 2 is the sectional view of Fig. 1.
In figure：1- base portions, 2- needle teeth.
Specific implementation mode
It, below will be to the technology of the utility model to keep the purpose of this utility model, technical solution and advantage clearer
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings.
Spin cotton cylinder metal needle cloth（Model AC2030 × 01550）, include in bandlet shape base portion 1 and be distributed on base portion 1
On needle tooth 2,1 width b of the base portion is 0.5mm, and the tooth pitch a of the needle tooth 2 on base portion 1 is 1.5mm, and operating angle α is 30 °.
Specifically, total high h of the base portion 1 and needle tooth 2 is 2.0mm, the tooth depth h of needle tooth 21For 0.45mm.Tooth depth h1It is small,
Backlash capacity is small, and the rate of transform is big, fills that fiber is few, and needle cloth load is light, advantageous to reducing cotton knot, and is not easy around cylinder；Tooth depth h1
Reduce, the air-flow that cylinder drives is few, and the influence of air-flow can mitigate.It advantageously reduces fiber to fill, fiber is made to be in needle cloth tooth
Nose part, the height x length that fiber exposes dial increases, with another dial（Flat-clothing）Contact length and effect increase, have
Alternating is combed conducive to fiber point, crawl gripping is strong, divides comb release orderly, to improve carding effect and even mixed effect.
Further, the teeth portion working face of the needle tooth 2 is concave surface arcuate structure, and the teeth portion back side is convex surface arcuate structure.
Tooth top area is small, improves sharpness, and tooth top area is smaller, and crown is sharper, stronger to the puncture ability of fibre bundle, more advantageous
Gripping, point comb in fiber and flock, reach that combing effect is good, and floating fiber is few, and cotton junction impurity is few, good excellent of cotton net sharpness
Point.
Further, wherein one side is vertical plane in the teeth portion two sides of the needle tooth 2, and other side face is inclined-plane.
It improves that needle cloth is anti-to roll intensity, makes needle cloth be not easy to run over and injure, and be not easy embedding broken seed.
Spinning cotton cylinder metal needle cloth provided by the utility model, with the characteristics of Optimal Parameters are improved in tooth form, base portion 1
Thickness be thinned, total high h is short, tooth depth h1Shallow, crown is close, and tooth top area is small, and operating angle is small, development characteristic design.Total height, can be with
Mitigate the load during needle cloth combs, increases Carding Degree.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with the power
Subject to the protection domain that profit requires.
