Description
Technical field:
The invention relates to textile machine, especially about the differential attachment of drawing frame even device of spinning usefulness.
Background technology:
Mixing in doubling step be spin before connecting in the short staple spinning process and after spin, yarn quality played an operation of key effect, this operation is intended to the sliver weight inequality of the long and short fragment after preceding spinning is revised, thereby fundamentally eliminate into the irregular defective of yarn count, improve the uniformity of resultant yarn.
Drawing frame (referring to Fig. 1) mainly is by the synthetic differential attachment of speed, the changes in weight that causes by the thickness difference according to the input sliver of detection means measure, change the speed of servomotor by the control module of setting, then with the constant motion of main transmission and the synthetic unidirectional continuous motion of fluctuation within the specific limits of variable motion of servo-drive, thereby in time change the drafting multiple of input sliver automatically, make the output sliver even thickness, reach the self-adjusting purpose of weight, at present employed to carry out the synthetic differential attachment of speed substantially all be the differential gear train structure of gear type to drawing frame, most typical is exactly the differential attachment that the RSB51 type autoleveller draw frame of being produced by Switzerland Rieter Perfojet shown in Figure 2 is adopted, this differential attachment has two central gear C1 and C2, this central gear C2 is driven by servomotor M1, the instruction that its rotating speed sends according to the checkout gear of drawing frame input sliver thickness and changing, this central gear C1 is an internal gear; Being hubbed on the planetary gear D of tie-rod E on cranking arm is engaged between two central gear C1 and the C2, tie-rod E obtains constant rotating speed by the gear B that it is arranged on the center axle head, planetary gear D then synthesizes a unidirectional continuous surge movement with above-mentioned variable motion and constant motion and passes to central gear C1, and export to corresponding drafter by its in-line gears A, carry out neat and well spaced to sliver.The differential machine machine of this gear type can reach changes in weight ± 25% sliver neat and well spaced to setting value ± 1% in.But this differential attachment noise is big, and noise more very became a pollution source of noise when especially speed was high, has limited its production efficiency simultaneously again; Secondly the manufacturing of gear requires height, the manufacturing expenses height, and maintenance is also complicated, difficult.
Summary of the invention:
The object of the invention is to provide the belt wheel differential attachment of the even device of a kind of drawing frame, solves the technical problem of noise under its high speed rotating.

Description of drawings:
Fig. 1 is that drawing frame is from mixing well schematic diagram of device.
Fig. 2 is the gear differential attachment schematic diagram of prior art.
Fig. 3 is a structural representation of the present invention.
The specific embodiment:
See also shown in 3, the present invention mainly is made up of driving pulley 1, planet belt wheels 2, passive belt wheel 4 and tie-rod 3.These planet belt wheels 2 are made up of two two intermediary's belt wheels 22 that are fixed in the same rotating shaft 21, and the diameter of these two intermediary's belt wheels 22 is decided on the needs of transmission.The axial line of this driving pulley 1 and passive belt wheel 4 is on the same straight line.This tie-rod 3 is one and has vertical 31 the axle of cranking arm, this end of 31 of vertically cranking arm is articulated in the rotating shaft 21 of these planet belt wheels 2, and this is cranked arm and 31 is provided with the length adjustment device (not shown), this length adjustment device can be superimposed with each other or the arm body of fit is partly formed by two that crank arm, and with the fastening location of screw, in order to regulate the rate of tension of driving belt; Also can form, perhaps the length adjustment device of other existing various structures by the positive and negative internal thread that the adjusting screw(rod) and being arranged on that two ends have positive and negative screw thread is respectively cranked arm in the 31 two ends arm bodies parts.
On the tie-rod 3 one group of planet belt wheels 2 can only be set, but be system's rotary balance, must be provided with corresponding counterweight block, with the vibration that centrifugal force was produced of these planet belt wheels 2 generations of balance.The present invention also can be provided with 2 to 4 groups of planet belt wheels 2, this moment tie-rod 3 should be provided with quantity identical crank arm 31 these crank arm 31 in vertical plane, to be symmetrically and arrange along circumference, obtaining the rotation of balance and stability, and counterweight block needn't be set.Each planet belt wheels 2 is connected with passive belt wheel 4 with driving pulley 1 with driving belt respectively.
This driving wheel 1 can be connected the input as the servo speed changing that changes with input sliver thickness as shown in Figure 3 with servomotor M1,3 of this tie-rods pass through the belt wheel of its central shaft end or gear 6 as shown in Figure 3 and are connected input as constant speed with general motor; Perhaps driving pulley 1 is connected the input as constant speed with general motor, and the central shaft of tie-rod 3 is connected the input as the servo speed changing that changes with input sliver thickness with servomotor M1; Passive belt wheel 4 is generally by coaxial belt wheel or gear 5 output as resultant motion, perhaps directly as output resultant motion is exported by the wheel shaft of passive belt wheel 4, drafting of sliver mechanism is passed in this unidirectional continuous motion that is output as fluctuation within the specific limits, thereby give suitable drafting multiple of sliver, make sliver thickness, weight unanimity, reach the regulation requirement.
