Abstract

The invention discloses a combined beater device suitable for a scutcher. The combined beater device comprises a beater roller body, and is characterized in that at least one set of beaters composed of sawtooth plates, card wire plates, saw web plates and smooth plates are arranged around the surface of the beater roller body, wherein the beaters are arranged in an orderly or orderless mode. The combined beater device overcomes the defects of existing scutchers, integrates advantages of various beater forms, and has the advantages of strong impact, much carding, sufficient impurity removal and less fiber damage.

Description

A kind of combination Beater arm device being applicable to scutcher

Technical field

The present invention relates to field of textile machinery, especially relate to a kind of combination Beater arm device for scutcher in opening picking or carding process.

Background technology

Scutcher is shredding impurity removing equipment crucial in opening picking or carding process.It does further shredding, removal of impurities to cotton block, both can make the big or middle assorted basic removing contained in flock, can make again the meticulous shredding of flock, for carding step creates good carding condition.Its Openability is strong, and dust removal rate is high, and its dust removal rate generally accounts for 40% ~ 60% of the total edulcoration rate of blowing flow process, and meanwhile, scutcher is also cotton knot, short flannel increases more equipment.Reduce cotton knot short flannel growth rate and improve dust removal rate etc. and have considerable meaning to raising spinning quality.

At present, the hired roughneck of scutcher mainly contains several types: saw bit beater arm, kirschner beater and garnet beater etc.

1, saw blade (nose shape) Striker Structure form is see accompanying drawing 1, Fig. 2.

Saw bit beater arm is by sawtooth blade 1 ˊ, block plate 2 ˊ, form every dish 3 ˊ, locking nut 4 ˊ and hired roughneck's axle 5 ˊ etc.Be connected with key by screw, nut between each parts, sawtooth blade arranges according to random ranking method.

Saw bit beater arm profile of tooth is large, and hitting power is strong, except large assorted effective, but also larger to fibre damage.Sawtooth blade can bear larger shredding power, good rigidly, and intensity is high, not easy fracture.

2, kirschner beater version is see accompanying drawing 3, Fig. 4.

Kirschner beater is made up of card wire plate 1-1, flange 1-2, hired roughneck's axle 1-3 and spindle nose 1-4 etc.Be formed by connecting by bolt, nut, pin and key etc. between each parts.

Kirschner beater to the effect of flock mainly combing shredding, instead of directly hits.Kirschner beater needle point is sharp, and puncture ability is strong, holds fine ability large; Needle point conically, smooth surface, little to fibre damage; Card wire density is large, and shredding is effective.

3, garnet beater version is see accompanying drawing 5, Fig. 6.

Garnet beater is made up of saw blade 2-1, hired roughneck's axle 2-2, roll body 2-3 and flange 2-4 etc.Connect by welding and gluing etc. between each parts and be formed by connecting.

Sawtooth needle is close larger than card wire, shredding better effects if; When the accurate combing of sawtooth, tiny trifle in the world exposes more abundant, advantageously in removal of contamination; The rectangular cross section of serrated surface, puncture ability, sawtooth and fibration, except adhesion friction power, also have a kind of very large plow frictional force, and therefore, garnet beater is large to fibre damage, produces short flannel many.Serration depth is shallow, and hold fine ability, flock is afterturn between hired roughneck and combing plate, easily produces cotton knot.

According to related tests, the technical indicators such as hired roughneck's pattern and degree of opening, dust removal rate, cotton knot, short flannel are closely related, and saw bit beater arm is to hit shredding, and card wire and garnet beater are based on combing shredding, therefore produce short flannel relatively less.From process raw material, saw bit beater arm mainly processes containing large assorted more raw material, and card wire and garnet beater mainly process containing little assorted, thin assorted more raw material.From hitting dynamics, the hitting power of garnet beater than card wire and garnet beater large.From shredding effect, garnet beater is better than kirschner beater, and kirschner beater is better than saw bit beater arm.

The form of a blade of single hired roughneck was unique in the past, in order to realize more preferably shredding impurity-eliminating effect, often needing one or more scutcher to have employed several dissimilar hired roughnecks and combinationally using.Than if any serial flow relationship two or three single scutchers, one uses saw bit beater arm, another then uses kirschner beater or garnet beater, and some flow processs adopt three roller scutchers, kirschner beater, thick garnet beater and serration hired roughneck combinationally use, and could realize the target of multiple effect.

Summary of the invention

Object of the present invention provides a kind of combination Beater arm device being applicable to scutcher for weak point existing in prior art just.

Object of the present invention realizes by following technique measures:

The combination Beater arm device being applicable to scutcher of the present invention comprises hired roughneck's roll body, is provided with at least one group in order or the hired roughneck be made up of gullet plate, card wire plate, saw blade plate and tabula rasa of lack of alignment around hired roughneck's roll body surface.

The length of length≤hired roughneck's roll body of gullet plate of the present invention, card wire plate, saw blade plate and tabula rasa.

Operation principle of the present invention and beneficial effect as follows:

Combination Beater arm device of the present invention combines the feature of multiple hired roughneck's form in the past, after cotton block enters hired roughneck room, has both been subject to the pound of saw blade, and can be subject to again the combing effect of card wire and sawtooth.Boll hull, mote, mote, broken seed etc. are mixed greatly under the thwack of saw blade point of a knife hits, and cotton block looses off, and under centrifugal action, departs from hired roughneck fast, enters dirt room; The needle point of card wire is sharp, and puncture ability is strong, can penetrate into cotton block depths, dismembers cotton block for tiny flock, is more conducive to being separated of impurity and cotton fiber; Bearded mote is under card wire, sawtooth combing effect and centrifugal action, and be fully exposed to cotton block surface, impurity end, by combing plate combing, makes it depart from fiber, falls into dirt room.This combination hired roughneck taken into account assortedly caducously broken, littlely assortedly fully to expose less greatly, the abundant combing of fiber and the process characteristic being separated, hindering less fiber, achieve many hired roughnecks (or roller), process task that multiple computer desk just can complete.

In sum, combination Beater arm device of the present invention, compensate for the deficiency that existing scutcher exists, absorbs the advantage of various hired roughneck's form, have that good thwack hits, many combings, fully removal of impurities and hinder the characteristic of fiber less.
