Description

The application of flax tape condenser in process of ramie spinning shredding and steel wire operation

Technical field

The present invention relates to the application in process of ramie spinning shredding and steel wire operation of the purposes of flax tape condenser, particularly flax tape condenser.

Background technology

Ramie just can be used for spinning after making degummed ramie, the technological process of production of ramie spinning is: degummed ramie → softening, oil supply, dewing → heap storage → pull fiber crops → shredding → steel wire → in advance also → combing → grilling → rove → spun yarn.Wherein shredding operation is the overcut fibre of breaking in the ramee mainly, and fiber is tentatively loosened, and generally adopts C111B, FZ001, FZ002 type opener; The steel wire operation mainly is that ramee is further carried out careful carding assembly single-fiber, adopts CZ191 type eckling machine more.The structure of opener and eckling machine can be referring to " (ramie spinning " the 124th～195 page of (textile industry publishing house in June, 1986 front page, chief editor: Jiang Fanchang, wide, the Zhou Yan of Shao), it mainly acts on is that degummed ramie is carried out combing, and combing is the important step in the ramie spinning production technology.Ramie degummed ramie after the softening heap storage still exists with the bundle fiber state, and its fibre length and the requirement of regularity incompatibility ramie spinning still can not direct spinnings, therefore the bundle fiber of degummed ramie must be separated into the filament state to adapt to the requirement of ramie spinning.

The main task that opener and eckling machine are finished is as follows:

One, utilizes card wire that fiber is carried out shredding and combing from coarse to fine, make fiber make in order out, be separated into the filament state from freeing under confusion is tangled state.

Two, in shredding and carding process fiber is broken, minimizing overcomes overcut fibre, to meet the process of ramie spinning requirement.

Three, the combing by opener and eckling machine make flax fibre head, in, the flax fibre of each position of tail and different brackets fully mixes as requested, makes the ramie stripes structure make every effort to even.

Four,, flax fibre is become continuous uniform ramie stripes by discontinuous, and neatly and regularly be enclosed in the ramie stripes bucket, for the continuous production of back operation is got ready by behind shredding and the steel wire.

It mainly is to finish by many big and small cylinders (various roller) that opener and eckling machine carry out combing to degummed ramie, one deck pin tooth (being needle plate, card clothing) coating is all arranged on the surface of all cylinders, near each other between each cylinder, distance is very little, sometimes even needle point is inserted mutually, fiber constantly divides comb and strips at a high speed therebetween.

The course of work of opener (referring to Fig. 2): the degummed ramie after the softening heap storage is pulled fiber crops send into fluted roll to 17 after feed numb curtain 16, fluted roll is a bit larger tham the numb curtain speed of feeding to 17 linear velocity, make fiber stretch parallel slightly and firmly gripped feeding to 17 and feed between numb roller 18 and the shell feed plate 19 by fluted roll, feed numb roller 18 and be surrounded by needle plate, spacing of its needle point and shell feed plate 19 is descending, under the passiveness of feeding numb roller 18 and shell feed plate 19 grips, enter cylinder 20 slowly.The surface of cylinder 20 is surrounded by needle plate, its speed is much larger than the speed of feeding numb roller 18, the card wire direction is mutually suitable on the contrary mutually with feeding numb roller 18 for the velocity attitude of cylinder 20, feeding the fiber of numb roller 18 all transfers on the cylinder 20, cylinder 20 takes fiber on the worker rollers 26 again, worker rollers 26 also is surrounded by needle plate and superficial velocity and cylinder 20 and differs bigger, the velocity attitude of worker rollers 26 and needle plate direction are opposite with cylinder 20, fiber has produced the branch comb at worker rollers 26 and 20 in cylinder, only the minority fiber is taken away by worker rollers 26, peeled by the numb roller 27 of stripping again simultaneously and return cylinder 20 and take away, ask numb cylinder 28 to hold up the fiber that is peeled and do not drop.Fiber on the cylinder 20 carries out the branch comb at second worker rollers 26, and its effect is identical with first worker rollers 26, and fiber is entering under the drive of cylinder 20 between cylinder 20 and the doffer 21.Doffer 21 also is surrounded by needle plate, its speed is less than cylinder, doffer 21 gyratory directions is opposite with cylinder 20 with the card wire direction, produce again and divide comb, the part fiber, is taken off by last drawing rollers 22 and following drawing rollers 23 on doffer 21 surfaces by aggegation, makes numb net, enter out between numb roller 24 and 25 through tubaeform sliver mouth, lend the gravity pressure of numb roller 25 and export closely the fiber crops band around to lapper, making the fiber crops volume.

The course of work of eckling machine (referring to Fig. 3): the fiber crops volume that opener is made is placed on the reel-off stand 30 of eckling machine, along with moving back the fiber crops volume, the revolution of creel roller 29 separates out, feed metal valley roller 32 through ramie supporting plate 31 and feed, and give branch comb rod 35 the fiber crops volume thus to pin rod 33.Divide on the comb rod 35 to be surrounded by sawtooth, thereby fiber is by minute comb 35 shreddings of rod and a combing, hairbrush 34 is mainly used in to remove to feed and passes to branch comb rod to the residual fiber on the pin rod 33 and take away, help hello to the gripping of pin rod 33.The fiber of being taken away on the branch comb rod 35 is transferred rod 36 transmission and meets with cylinder 37.Be surrounded by card clothing on the cylinder 37, its superficial velocity manys times soon than shifting rod 36, fiber on the transfer rod 36 is seized by cylinder 37 and is advanced by its pin tooth gripping, when advancing to worker rollers 39, fiber, is used to deprive and gets small amount of fibers that worker rollers 39 takes away and fiber is returned cylinder 37 and shell numb roller 38 by a minute comb at worker rollers 39 and cylinder 37 pin between cog.Fiber divides with the numb roller 38 of stripping repeatedly at four groups of worker rollers 39 to be combed and strips, fiber on cylinder 37 contacts with doffer 40, because of doffer 40 surfaces are surrounded by card clothing, its pin number and density are slower than height and speed on the cylinder 37, so fiber by aggegation on doffer 40 surfaces, from cylinder 37 to doffer's 40 transfer processes fiber again by combing.Aggegation fibrage on doffer 40 meets with the numb rod 41 of stripping, shell numb rod 41 surfaces metallic card clothing is also arranged, under the effect of pin tooth, fibrage on the doffer 40 is transferred to transfer roller 42, warp nip roll 43 up and down peels into numb net, the fiber crops net becomes ramie stripes through supporting plate 44, can coiler 45 (having horn mouth and nip roll fibrage to compress on it) output, puts into ramie stripes bucket 46 regularly.

Application opener and eckling machine carry out combing to ramie degummed ramie fiber and have following shortcoming:

One, opener and steel wire machine utilize cylinder pin tooth that fiber is carried out brute force to divide comb repeatedly and strip, and fiber divides at a high speed comb and strips between each cylinder, and the probability that produces the fiber crops grain is bigger, and fiber is opened fine balling-up, make the fiber after the combing have more fiber crops grain.

Two, opener and steel wire machine utilize cylinder pin tooth that fiber strength is divided comb repeatedly and strips, and fiber is opened fine balling-up, its part fiber crimp, part produces hook, part is mutually twined kink, and it is not very straight making the fiber after the combing, and the back operation is had a negative impact.

Three, fiber divides at a high speed comb and strips between each cylinder, because distance is very little between each cylinder, so it has carried out unnecessarily breaking to the fiber that part meets the length requirement that spin, and is big to fibre damage, causes the short fiber increase, causes the combing card yield low.

Flax tape condenser applies to the spinning of flax comb growth fiber crops, be first procedure in flax ramee spinning technology---the equipment that uses in flax slivering operation, it mainly acts on is the length ramie stripes that a branch of bundle heckling machine comb growth fiber crops are made successively, have certain fineness and even structure, on drawing frame, carry out then and close drawing-off, make strip even, for flax ramee spinning of back is prepared.At present, document record and the report that does not have flax slivering in process of ramie spinning, to use.

Summary of the invention

The purpose of this invention is to provide the new purposes of flax tape condenser in process of ramie spinning, provide the application of flax tape condenser in process of ramie spinning shredding and steel wire operation specifically, replace opener and eckling machine that ramie degummed ramie fiber is carried out combing with flax tape condenser, the bundle fiber of ramie degummed ramie is separated into the filament state to adapt to the requirement of ramie spinning.

With reference to " flax spinning technology " the 92nd～99 page of (Heilungkiang science tech publishing house, chief editor: Yu Cuiying, Xia Jingyi) disclosed content and Fig. 1, flax tape condenser of the present invention is mainly right by feed mechanism, drafter, guide, shaping metallic roller, compositions such as can coiler, layering device, ramie stripes gauging machine device.Feed mechanism is made up of the numb belt 1 in shop, shop numb belt transmission rod 2 and guide 3, mainly be with comb fiber crops fiber crops bundle by behind the technological requirement lay hello to machine, and send into drafter, be held when making it be subjected to drawing-off.

The pressurization top roller 10 that drafter is made by metallic roller under the drawing-off 8 and elastomeric material, feeding metallic roller to 4 and 5, faller gill mechanism 6 (mainly being made up of up screw rod and descending screw rod and many needle plates), guide 7 and lever roller pressing mechanism 9 are formed, and mainly are that feeding flax ramie stripes is extended drawing-down equably.

Supporting plate 13, fiber crops pages or leaves buncher 11, strip-producing roller to 15 and 14, can coiler, layering device, ramie stripes gauging machine device mainly be can be with certain cast and certain-length lay-up in the bar bucket, for the feeding of next procedure is prepared with the output ramie stripes.Wherein strip-producing roller to 15 and 14, can coiler is positioned at the right side that flax tape condenser goes out the fiber crops end.

When flax tape condenser uses in shredding and steel wire operation, be through numb belt 1 feeding of feeding of flax tape condenser with the degummed ramie after the softening heap storage, the fibrage that moves is through feeding guide 3, after making the certain width of tool at the beginning of the fiber crops layers, enter and feed numb roller 4 and 5, with fibre guide faller gill district 6, fiber carries out compartition between the pin in guiding faller gill district 6, parallel, remove part hards and impurity, after again fiber being sent into drawing-off guide 7, be that drafted roller is to 8,10 grip, at this moment through drawing rollers to 8,10 constantly extract fiber, because of ramee is not fitly to arrange, but filament staggers and hangs together, thus under the gripping of faller gill through the flax tape condenser drawing rollers to 8, basically become the filament state after 10 extractions.Feed the ramee of numb belt feeding after drawing-off is extracted through flax tape condenser, enter bar bucket 12 to being combined into one after 15,14 through can coiler by supporting plate 13, fiber crops pages or leaves buncher 11 and strip-producing roller successively, thereby formed the ramie stripes of filament continuously, in order to entering subsequent processing through mixing.Thereby realize the application of flax tape condenser in process of ramie spinning shredding and steel wire operation.

In process of ramie spinning shredding and steel wire operation, use flax tape condenser and produced extremely useful effect:

One, because the flax tape condenser needle plate speed of service is slower, and its combing to flax fibre is slowly carried out, so the generation of the fiber after combing fiber crops grain is less, the fiber crops grain in the ramie strip can reduce more than 70%.

Two, flax fibre is in straight state always in flax tape condenser, after faller gill carries out combing to flax fibre, through drawing rollers ramee is extracted drawing-off again, further made the straight degree of fiber in order, so fiber is straight, not disorderly in the ramie strip, for following operation is laid a good foundation.

Three, because flax tape condenser only is to utilize drawing rollers that ramee is extracted, the fibre weight of being broken is reduced, and the damage of fiber is little, and through the combing test, the ramee card yield can improve 8-11%, has greatly improved economic benefit.
