Abstract
The utility model relates to a bobbiner with a yarn tension testing mechanism and a tension actuating mechanism. The tension testing mechanism is arranged between the bobbiner and a front roller. The tension actuating mechanism for adjusting the lifting or falling of a rope is arranged on the back area of a cone pulley belt rope, wherein, the tension testing mechanism mainly comprises a plurality of infrared photoelectric sensors, and the tension actuating mechanism mainly comprises an adjusting cam. The utility model can realize the automatic adjustment of the yarn tension under a working state for detecting the yarn tension in a contactless mode and adjusting a cone pulley belt in a bidirectional fine mode. The utility model is suitable for various bobbiners of which the cone pulley belts are moved via the pull of the ropes.
Description
The utility model relates to a kind of Speed frames, particularly a kind of Speed frames with yarn tension detection and executing agency.
In existing Speed frames, the normal winding of flyer bobbin is to rely on the cone pulley transmission to realize, cone pulley is then stirred by the belt by the weight pulling under the tension compensating mechanism control.Wherein, tension compensating mechanism has disc type and various ways such as guide tracked, and this class mechanical type tension compensating mechanism all is to discharge and the tension pull rope according to certain Changing Pattern, to realize the control to cone pulley, guarantees that the percentage elongation of yarn reaches unanimity as far as possible.Yet owing to the adjustment to compensation arrangement is that the people is for carrying out; belong to seizure, presetting system; promptly to when driving, find strain problem; shut down then and regulate; the checking of driving again is through repeatedly just finishing after repeatedly, so this compensation arrangement workload in application is big; also be difficult to accurately, and every adjustment once all to influence 1/6 or 1/3 section of belt total travel.In addition, for the tension variation that takes place at random in the course of work, this compensation arrangement can not be adjusted thereupon.
The purpose of this utility model, be at above-mentioned defective of the prior art, and propose a kind ofly to have yarn tension and detect Speed frames with executing agency, it can carry out contactless tension force to yarn and detect, through the signal conversion, be controlled at the executing agency that cone pulley belt back zone installs additional, thereby regulate cone pulley as required, guarantee the uniform tension in order of yarn.
The purpose of this utility model is to realize like this.
Have the Speed frames of yarn tension detection and executing agency, comprise flier formula Speed frames and control circuit by cable traction cone pulley belt.In the utility model, between the front roller 7, a tension-detecting mechanism is installed at the flier 1 of Speed frames; On the back zone of Speed frames cone pulley belt rope 8, be equipped with one and adjust the Tension Control executing agency that rope raises or reduces.
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
Fig. 1 tension-detecting mechanism schematic diagram;
Fig. 2 sensor schematic diagram;
Fig. 3 tension force executing agency schematic diagram.
Tension-detecting mechanism with Speed frames of yarn tension detection and executing agency is to arrive between the front roller 7 at one or more fliers 1, and an infrared photoelectric sensor 6 is installed respectively, and the luminous tube 5 of sensor and the line of receiving tube 4 are perpendicular to yarn 3 positions.And the luminous tube on the sensor is one, and receiving tube has one or more.
Tension-detecting mechanism of the present utility model is to efflux three flier place sensor installations at Speed frames, and sensor is provided with six receiving tubes.
Tension force executing agency with Speed frames of yarn tension detection and executing agency is that a curve that is driven by micro machine is the cam 10 of spiral of Archimedes.Be equipped with near switch at place, summit, both sides at cam.
Operation principle of the present utility model is: the rove between front roller and flier false twist device 2, pass through from the flute profile sensor stand simultaneously.Do when the rove bar and only to stop that when receiving with the horizontally disposed 1# receiving tube of luminous tube, sliver tension force is big; Have trace sagging or beat when the rove bar is dried, sliver tension force is moderate in the time of can stopping 1# and following 2# receiving tube; When the rove bar is done sagging or the 3# under can stopping again of beating, even during the 4#-6# receiving tube, sliver tension force is then little, or too small.For the tension state signal that sensor receives, control circuit is made reflection immediately, when sliver tension force is big, make micro machine counter-rotating operation, the cam counter-rotating, the height that the belt rope on the cam arches upward reduces, thereby the belt trace moves to left, and the roving bobbin rotating speed is descended, and makes tension force from large to small.Sliver tension force hour makes micro machine just transport row, and cam just changes, and the height that the belt rope on the cam arches upward increases, thereby the belt trace moves to right, and the roving bobbin rotating speed is risen, and tension force is changed from small to big.
In order to get rid of the tension variation of indivedual slivers that cas fortuit causes, tension-detecting mechanism adopts three sensors to detect respectively, when having only three sensors all to detect identical tension state, just executing agency is regulated, avoids wrong generation.Simultaneously, in order to protect machine, cam is rotated in and arrives summit (highs and lows of cam) before, near switch circuit is closed.
Advantage of the present utility model is as follows:
1, can realize that the yarn tension under the duty regulates automatically, guarantee that even yarn tension is consistent, improve the quality of products.
2, yarn tension is carried out contactless detection, neither affect the tension force of yarn, also spinning quality is not impacted, and detect the position near the outgoing position of yarn, tension state is the most accurate.
3, by the forward and backward rotation of cam, the cone pulley belt position can be regulated by two-way trace, also makes the mechanical tension system increase feedback element, has realized closed-loop control.
4, the utility model is applicable to the flier formula Speed frames that various cone pulley belts are moved by cable traction, also can install and use on existing these type of Speed frames.
