Description

The transmission device of the detaching roller of combing machine

Technical field

The invention belongs to textile machine equipment, be specifically related to a kind of transmission device that is used for the detaching roller of combing machine.

Background technology

Combing machine has combing combination and at least one pair of detaching roller of a sealing, detaching roller can be in advance with in the last working cycles (separation) web of combing pour in the machine, and in time pincers are held and are sent here by nipper, just by the palpus Cong Qianduan of cylinder combing, and above the superimposed web in pouring machine into of these fiber front ends, because the movement velocity of detaching roller significantly surpasses the speed of advancement of nipper, therefore the fiber of having been held by pincers is exported at a high speed, and from nipper, take out and draw (separation) and come out, in separation process, because nipper continues forward, so this pincers are held, superimposed (joint) takes out row (separation) process also is the carrying out that continue.Under present state of the art, these are well-known, and detaching roller generally is paired, the forward and backward motion with cycle pitch motion.This seesawing of detaching roller depends primarily on cylinder, the direction rotation that cylinder advances towards sliver.The device that is used to drive axle that difference turns to and cylinder and detaching roller is all by machine driving control, and the angular speed of the effective length of delivery of detaching roller and detaching roller can not change.

Summary of the invention

Technical problem to be solved by this invention provides a kind of transmission device that is used for the detaching roller of combing machine.In this technology, first motor is controlled all rollers of drafting system, nipper and carding movement (linear and circle) by mechanical transmission method combining.Two motors are synchronized with the movement to the pair of separated roller respectively and carry out single driving respectively in addition.These motor interdependences, and these motors are installed in the encoder control on cylinder and the detaching roller axle respectively.Use three motors, eliminated the part of complicated mechanical transmission.Motor has an interactional adjustment, can be soft by computer, hardware is programmed to this adjustment and revise.On the rotary pulsed basis of angle rotary pulsed in the angle that the encoder by the cylinder system provides and that the detaching roller transmission system provides, determine the driving of detaching roller motor.

The present invention is achieved by the following technical solutions: a kind of transmission device that is used for the detaching roller of combing machine comprises first motor 101, drafting system 15, nippers 13, nipper plate 14, cylinder 5,

guide roller

The specific embodiment

A kind of transmission device that is used for the detaching roller of combing machine comprises first motor 101, drafting system 15, and nippers 13, nipper plate 14, cylinder 5,

guide roller

10,11, delivery roller 9 is given cotton roller 6, and jockey pulley 3 holds volume roller 1,2; Hairbrush motor 102, hairbrush 4; First motor 101 connects to hold by drafting system 15 rolls up roller 1,2, jockey pulley 3, and cylinder 5 is given cotton roller 6, nippers 13, nipper plate 14, delivery roller 9,

guide roller

10,11; Hairbrush motor 102 drives hairbrush 4; Cylinder 5 is provided with the 3rd encoder 201; First detaching roller 7 is connected with second motor 103, is connected with first encoder 202 on second motor 103; Second detaching roller 8 is connected with the 3rd motor 104, is connected with second encoder 203 on the 3rd motor 104.

Can find that according to above-mentioned figure 301 refer to input web part, 302 are web part after the combing, that is to say combing after web behind pressure roller, become sliver 303.

Whole work comprises a pair of

guide roller

10,11, and delivery roller 9 is given cotton roller 6, cylinder 5, and jockey pulley 3 holds volume roller 1,2, is at first driven by first motor 101, is furnished with the 3rd encoder 201 on 5 in the cylinder.Be furnished with first, second detaching

roller

7,8, separate roller 7 ', 8 ', directly drive by second motor, 103, the three motors 104, be furnished with first, second encoder 202,203 on the motor shaft.12 refer to top comb, and 13 refer to nippers, and 14 refer to nipper plate.

Therefore, in Fig. 1, the motor-driven function.

---the first, the first motor 101, drive two by transmission device 15 and hold volume roller 1,2, make lap gently carry out unwinding web 301; By jockey pulley 3, to cotton roller 6, enter nippers 13 and nipper plate 14.Through cylinder 5 combing webs 301.

---the second, second motor 103, the 3rd motor 104 of being furnished with encoder drive first, second detaching

roller

7,8.

---the 3rd, the only clockwise direction rotation of first motor 101 of being furnished with first encoder 201 drives cylinder 5 by drafting system 15, and cylinder 5 is controlled by corresponding first encoder 201,

Particularly reconnect with

nipper

13,14 and cylinder after pile be placed on very soon detaching roller on afterbody, top comb 12 can move around to first detaching roller 7, and nipper the 13, the 14th is opened, carry out simultaneously with top pile part and facing on first detaching roller 7, like this, can obtain pile overlap joint (at of the top with of bottom) when direction of rotation restarts forward has detaching roller to clamp, referring to Fig. 2.

Must overlap under the exact state, fully with accurately the tightness overlap joint is to form uninterrupted sliver in order to obtain, and circulation generates sliver thereby pass through step by step.

Particularly following separation---combing and overlap the operation cycle situation once more:

---when nipper clips the fiber pile when retracting and hanging downwards, nipper is in closed condition.

---under pile, the direction of rotation of combing cylinder is opposite with nipper direction (forward), and combing cylinder is engaged in the combing work of the pile of suspension.

---nipper starts forward once more, opens a moment later, and simultaneously, detaching roller rotates backward, for obtaining enough pile parts, allows pile to be overlapped in detaching roller forward.

In case---finish overlap joint, just under the state that nipper is opened, make detaching roller clockwise, and drag all webs forward.

---web giving between cotton roller 6 and nipper plate 14 tops clamped.

---simultaneously, last sliver fiber is forward inserted in top comb.

---therebetween, the nipper of opening begins new work then in revolution of the pile place on top and clamping.

Fig. 3 has shown the angle value of motor with different parts operating conditions:

From angle Fig. 3, can obviously find out:

-I-I 35 calibration-3.5 calibration, expression combing cylinder 5 carries out the combing angle-differentiated;
