Servo motors of the middle and the back rollers drive the middle roller and the back roller respectively through a driving device of the middle roller and a driving device of the back roller. The utility model has the advantages of big driving power, simple transmission, stable draft ratio and good quality of the fiber. The utility model provides guarantee for the numerical control and automation of the ring spinning frame.
Description
Affiliated technical field
The utility model relates to a kind of ring throstle, particularly is suitable for the numerical control drafting system of ring spinner.
Background technology
Drafting system is the important component part of ring throstle, roller all is by an asynchronous motor before, during and after in traditional drafting system of ring spinner, transmission system by complexity drives, preceding to realize, in, roller and in, different draw ratio (gearratio) between the rear roller, not only transmission complexity of this structure, adjust inconvenience, and the spinning suiting performance is limited, is difficult to realize automation.In order to overcome these deficiencies, Chinese invention patent application (publication number CN1074494A) specification disclosed " digitally-controlled spinning frame " has appearred resembling, it drives the drawing-off drive unit of front roller and middle rear roller respectively with two stepper motors, though this drive unit has simplified transmission mechanism, help improving the automaticity of fine spining machine, but there is the driving power deficiency in stepper motor, the scope of application is little, more because the existence of the step-out phenomenon of stepper motor, particularly at start-up period, before causing, the unusual fluctuations of first break draft ratio have increased end breakage rate, are having a strong impact on quality index such as the one-tenth sliver is dried.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides the ring throstle drawing-off drive unit that a kind of draw ratio is stable, yarn quality is good, and not only driving power is big for it, transmission is simple, and helps the automation of fine spining machine.
The technical scheme that is adopted that the utility model solves its technical problem is: drafting system of ring spinner of the present utility model comprises the left and right front roller that is arranged in parallel, middle roller and rear roller; The front roller servomotor drives front roller by the front roller transmission mechanism; Middle rear roller servomotor drives middle roller and rear roller by middle roller transmission mechanism and rear roller transmission mechanism respectively.
After adopting said structure since with servomotor as power source, not only driving power is big, applied widely; And avoided the step-out phenomenon of stepper motor, and the draw ratio between roller is reliable and stable, and priming speed is level and smooth, advantageously guarantees the raising of yarn quality and the reduction of end breakage rate.Also since adopted front roller and in, the driving respectively of rear roller, simplified transmission mechanism greatly, made things convenient for the spinning process adjustment, help realizing the numerical controlization of fine spining machine, improved the automaticity of fine spining machine.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a kind of ring throstle drawing-off drive unit transmission schematic diagram of the present utility model.
The specific embodiment
Ring throstle drawing-off drive unit shown in Figure 1, the left and right front roller 1,12 that is arranged in parallel is installed on fine voile machine, left and right middle roller 2,11, left and right rear roller 3,10, the front roller 12, middle roller 11 and the rear roller 10 that are positioned at the left side are opposite with the direction of rotation of the front roller 1 that is positioned at the right side, middle roller 2, rear roller 3.Front roller servomotor 25 is by the left front roller gear 30 in travelling gear 27,28, the 29 driving left sides of front roller motor gear 26 and engagement successively, to drive left front roller 12 rotations; Front roller servomotor 25 also drives the right front roller gear 22 on right side by the travelling gear 24,23 of front roller motor gear 26 and engagement successively, to drive right front roller 1 rotation.Middle rear roller servomotor 17 drives left middle roller gear 13 by the travelling gear 16,15,14 of middle rear roller motor gear 18 and engagement successively, to drive left middle roller 11 rotations; Middle rear roller servomotor 17 also drives right middle roller gear 21 by the travelling gear 19,20 of middle rear roller motor gear 18 and engagement successively, drives right middle roller 2 rotations.Middle rear roller servomotor 17 drives left back roller gear 9 by middle rear roller motor gear 18 and travelling gear 16,15,7,8, drives left back roller 10 and rotates; Middle rear roller servomotor 17 drives left back roller gear 4 by middle rear roller motor gear 18 and travelling gear 19,6,5, drives right back roller 3 and rotates; Travelling gear 15,7 and 19,6 is fixedly connected respectively, and they have identical turning to and rotating speed.
During work, according to spin technological parameters such as thin yarn number number and total draft distribution, determine the rotary speed ratio of front roller, middle roller, rear roller, thereby directly set the output speed of front roller servomotor 25 and middle rear roller servomotor 17, travelling gear need be do not changed, just the spinning process variation of parameter can be realized; The numerical controlization that so not only helps ring throstle makes operation more convenient flexibly, and technology is easy to adjust quick, and the employing of servomotor, has both guaranteed the stable of technological parameters such as draw ratio, has improved the spinning suiting scope and the running efficiency of fine spining machine again.
The utility model is not limited to above-mentioned embodiment, the set-up mode of travelling gear and quantity all can be made corresponding adjustment in its front roller transmission mechanism, middle roller transmission mechanism, the rear roller transmission mechanism, these transmission mechanisms also are not limited to adopt gear drive simultaneously, can also adopt band transmission, gear---the corresponding kinds of drive such as band transmission.Therefore, under the prerequisite that does not break away from the utility model principle, some modification and the improvement done all should be considered as in protection domain of the present utility model.
