Description
Technical field
The utility model relates to the ring throstle of spinninging technical field, relates in particular to the drafting system of ring throstle.
Background technology
The drafting system of ring throstle is that the rove of feeding or strip are taken out the finished product spun yarn that long drawing-down becomes to have certain special number equably.Therefore the structural shape and the run stability of drafting assembly of spinning frame not only directly affect the quality index of resultant yarn, and are determining the prouctiveness of fine spining machine itself and even whole spinning technological process.
The drafting system of tradition ring throstle adopts the two cushion rubber drawing-off structural shapes of three rollers mostly, it is that the boundary is divided into two draw zones with drafting system with the middle roller, make it between front roller and middle roller, to form the front draft zone, between middle roller and rear roller, then constitute the first break draft district.Generally adopt the two cushion rubber drafting systems of elastic nip in the front draft zone, this drafting system can be implemented effectively to grip and better controlled to the proparea fiber movement; Then draw zone lacks the fiber movement necessary control owing to adopt the drawing-off of simple roller straight line, thereby can not bring into play the positive role of back area draft.
In order to improve the drawing-off quality in first break draft district, people have designed V-type drawing-off structure, it is that certain altitude and suitably reach are raised with respect to the drawing-off plane in the rear roller position, again will the back roller certain distance (or angle) of setovering backward, this just makes the fiber strip in first break draft district form grip hold arc on rear roller, to expand rear roller friction field intensity distributions, also shortened noncontrolled area length simultaneously.On this basis,, designed again in the back zone fiber control roll has been set, strengthened the control action of first break draft district, improved the drawing-off ability, thereby obtained the effect of improving first break draft district yarn quality fiber strip for further strengthening control to first break draft district fiber.
But, no matter be with two cushion rubber controls in the front draft zone, still adopt the V-type drawing-off in the first break draft district, or install control roll again additional, the middle roller of this three roller devices always has the cushion rubber roller of a pair of frictional drive, and it is the rear roller of front draft zone, plays the control action to the front draft zone yarn, be again the front roller in first break draft district, play drawing-off guiding function first break draft district fiber strip.Because the motion of apron is a frictional drive, the cushion rubber up and down of middle roller generally always exists smooth and the irregular phenomenon of speed, thereby causes forward and backward district drafting process instability, and the increase drawing-off is irregular.Particularly in high drafting, feed increasing the weight of of regular roving feeding, the back zone is adopted the V-type drawing-off and is added under the situation of control roll, the drafting force in first break draft district enlarges markedly, interference and resistance have also just more been aggravated to the cushion rubber motion, cushion rubber kinetic stability and synchronism sharply descend about making, do thereby worsen into sliver, increase resultant yarn yarn defect, also increase the yarn quality difference between ingot simultaneously.Therefore the total draft multiple of three traditional roller drafting devices all is no more than 60 times, is restricting the raising of ring spinning prouctiveness.
Although four roller super draft devices occurred, disclose the two cushion rubber drafters of a kind of fine spining machine four rollers as Chinese utility model patent (the ZL patent No. 03217784.4), this drafting device with four rollers is actually by increasing the roller logarithm, reaches increase total draft multiple purpose by increasing draw zone quantity.It is when increasing the total draft multiple, can produce the drafting wave synergistic effect, make the spun yarn bar do variation, the thickness joint increases, particularly long details increases, cause that the spinning end breaking rate increases, this to sacrifice the way that product quality reaches increases drafting multiple, can not reach the synchronous raising of drafting multiple and yarn quality.
