Summary of the invention
The purpose of this invention is to provide a kind of fine spining machine that starts described type, use this fine spining machine, especially at the condensation region end, rove can reach certain degree of compression, especially for the cohesion of the unmanageable fiber of being made up of chemical fibre, problem can be well solved.In addition, the requirement for reduce the transporting velocity of rove at twisting end-blocking roller inner region and twisting end-blocking roller front region can reduce this speed significantly according to fine spining machine of the present invention.
According to following feature of the present invention, promptly twist the rotation of end-blocking roller and the rotation of coacervating part and tilt mutually, just form non-0 ° of angle α, can be resolved as this task of the object of the invention.Therefore, according to the present invention, the rotation of twisting end-blocking roller is not parallel to each other mutually with the rotation of cohesion element and seems extremely important.
Therefore, from then on feature is of the present invention as can be seen will be intended to a kind of very simple mode, promptly only will twist the end-blocking roller and tilt to place a little, thereby reduce the peripheral speed of twisting the end-blocking roller.Between perforated cage and twisting end-blocking roller surface, formed a speed discrepancy that depends on the two angle of cut, so, the rove that is delivered between cohesion element and twisting end-blocking roller can obtain an average speed, i.e. speed between Jie's perforated cage and the twisting end-blocking roller peripheral speed.
For forming described angle α, preferably will twist the end-blocking roller tilts to place around tilt axis, and tilt axis is overlapped with perforated cage contact point place at twisting end-blocking roller with the radius of coacervating part, the twisting end-blocking roller that promptly tilts occurs in the radius of perforated cage and is positioned at perforated cage and the contact point scope of twisting end-blocking roller.Thereby the peripheral speed of twisting end-blocking roller reduces by the coefficient that is relevant to this inclination angle cosine.
Therefore, the bus of twisting end-blocking roller can be done and be in line.
For obtaining long closing line, preferably will twist the bus of end-blocking roller and make curve, thereby make the closing line of coacervating part and twisting end-blocking roller become longer, particularly long than the axial length of twisting end-blocking roller with the related closing line in angle of inclination.
Also can place twisting end-blocking roller in the following way, be angulation β, to twist the end-blocking roller tilts to place around tilt axis, make tilt axis perpendicular to the radius of coacervating part with the contact point place of twisting end-blocking roller, also perpendicular to the plane that forms by the rotation of twisting end-blocking roller and/or perforated cage, in this case, twisting end-blocking roller should be designed to be tapered vertically, especially form cone, and the coning angle of described cone is equivalent to twist 2 times of angle β of the rotation of the rotation of end-blocking roller and perforated cage.
Preferred inclination angle scope is: angle [alpha], β is between 1 ° to 20 °, and is better, particularly best between 7 ° to 8 ° between 5 ° to 10 °.
Preferably select to allow twisting end-blocking roller have the twisting end-blocking roll material of hard relatively outer surface.
But, because now rove is to pass from path elongated between sieve roller and the twisting end-blocking roller, and the speed discrepancy between sieve roller and the twisting end-blocking roller is to rove and have no adverse effects, should allow twisting end-blocking roller comprise the resilient flexible outer surface, and coacervating part placed very position near twisting end-blocking roller outer surface, thereby make coacervating part be pressed into the surface of twisting end-blocking roller slightly.In this embodiment, the busbar of twisting end-blocking roller can be in line, thereby the advantageous particularly that seems.

The specific embodiment
According to Fig. 1, rove 17 is introduced in a pair of guide-in roller 22 of drafting system 11, for position from then on be directed to through preliminary draft district 23 with another of apron 25 collaborative works to running roller 24, exit at this running roller, rove is led in the output gap of drafting system 11, and this output gap is formed between perforated cage 13 and the output pressure roller 14.Main drawing area 34 is between the contact wire of the output gap of apron 25 and output pressure roller 14 and perforated cage 13.Along in the certain angle scope of the inner surface of perforated cage 13, be provided with the suction box 27 of extension, suction box 27 is connected with suction tube 26.On the outer circumference surface of suction box 27, suction box 27 comprises the suction slotted hole 28 (Fig. 2) that extends along its circumferencial direction, thus, the hole 29 that is distributed in suction slotted hole 28 tops by perforated cage 13 just can produce the suction air flow that acts on the rove 17 that is attached on the perforated cage 13, thereby makes rove 17 obtain cohesion.
Next within the angular distance at 45, the throughput direction in output pressure roller 14 back along rove, twisting end-blocking roller 15 is resisted against on the perforated cage 13 in the same way.Between output pressure roller 14 and twisting end-blocking roller 15 is condensation region 12.Twist thread and 17 ' come out from the twisting end-blocking gap of twisting end-blocking roller 15 just to extend towards the ring spinning apparatus 30 of reality.
According to Fig. 2, twisting end-blocking roller 15 tilts to place with respect to perforated cage 13 around tilt axis 35, and tilt axis 35 overlaps with the contact point place of perforated cage at twisting end-blocking roller 15 with the radius of perforated cage 13.Thereby the rotation 18 of twisting end-blocking roller 15 and the rotation 19 of perforated cage 13 form angle α, thereby the contact zone of perforated cage 13 and twisting end-blocking roller 15 is positioned at the zone at tilt axis 35 places.Make pressure release surface if will twist end-blocking roller 15, perhaps that it is more close with respect to perforated cage 13, allow the two be not only a contact, then this contact area can increase.
Because the existence of the angle of cut α of rotating shaft 18,19, thereby with respect to self being driven the sieve roller 13 that drives described twisting end-blocking roller 15 rotations, the twisting end-blocking roller 15 of non-drive is to hang down the peripheral speed rotation of some.The peripheral speed of twisting end-blocking roller 15 reduces by the coefficient that is relevant to angle [alpha] cosine.
Thereby, in the course of work of fine spining machine, twisting end-blocking roller 15 to be rotating than the lower peripheral speed of perforated cage, thus make rove in the zone, abutment of perforated cage 13 and twisting end-blocking roller 15 or region in front have certain degree of compression and/or slackness.
Have a bit extremely important, promptly twist end-blocking roller 15 drive source of oneself can not be set, but by being driven with driving contacting of perforated cage 13 surfaces, also, because the existence of angle of cut α, twisting end-blocking roller 15 is done the rotation that speed reduces.
In order to realize the cylindrical twisting end-blocking roller 15 among Fig. 2, its bus 36 is done and is in line.
But, if expect longer closing line between perforated cage 13 and the twisting end-blocking roller 15, then bus 36 ' will make the concave shaped among Fig. 2 in varying degrees.The radius of this kind bus is decided according to the radius of perforated cage 13 and twisting end-blocking roller 15 and the angle α of rotation 18,19, thereby makes closing line extend to required length.
In the embodiment shown in fig. 3, be provided with two adjacent and be in perforated cage 13 on the same axis, each perforated cage all is furnished with twisting end-blocking roller 15 ' separately.Herein, two twisting end-blocking rollers 15 ' are tilting around tilt axis 35 ' equity, tilt axis 35 ' is perpendicular to the radius of perforated cage 13 in the contact point zone of perforated cage 13 and twisting end-blocking roller 15 ', this setting can obtain as follows: by mode shown in the figure two twisting end-blocking rollers 15 are made cone by opposite direction, and the closing line that its outer surface extends vertically is resisted against on the outer surface of perforated cage 13; Thereby between rotation 18 ' and 19, formed relative angle β.Twisting end-blocking roller 15 ' is supported rotationally by the driving shaft 37 that tilts with pivot center 18 ' at bearing 38 places.
Conical twisting end-blocking roller 15 ' is with certain rotating speed rotation, and this rotating speed is equivalent to twist the rotating speed of path portion in the end-blocking roller 15 '.Therefore, this condition is set up: the radius of perforated cage 13 multiply by the middle footpath that its angular speed equals to twist end-blocking roller 15 ' and multiply by its rotating speed.This only just means at the middle part of twisting end-blocking roller 15 ', does not just exist speed discrepancy between twisting end-blocking roller 15 ' and the perforated cage 18, and has produced speed discrepancy in the smaller relatively end of diameter, means carrying rove so far to produce trigger action.
On the other hand, the peripheral speed of the diameter the best part of twisting end-blocking roller 15 ' is greater than the peripheral speed of perforated cage, and this fibre bundle that will cause being transported between perforated cage 13 and the twisting end-blocking roller 35 ' produces acceleration.
And in the embodiment according to Fig. 1 and Fig. 2, the rotation 18,19 that mutually tilts is also non-intersect, promptly is not arranged to crossing mode, and in the embodiment according to Fig. 3, two rotations 18 ' and 19 intersection points that have separately.
Therefore, essential characteristic of the present invention is that the rotation 19 of rotation cohesion element 13 is not parallel to each other mutually with the rotation 18,18 ' of twisting end-blocking roller 15,15 '.
