Background
The yarn of the twisting machine is driven by a spindle assembly to rotate at 4000-10000 rpm outside the spindle pot to form a rotating outer diameter, the diameter of the rotating outer diameter greatly affects energy consumption and finished product quality, the energy consumption is increased sharply due to the overlarge rotating outer diameter, the energy consumption can be increased by 30%, and the finished product quality is affected by yarn breakage accidents caused by the friction between the yarn and the spindle pot due to the undersized rotating outer diameter.
In the prior art, a scheme of observing the rotating outer diameter of the yarn by using a sensor is provided. For example, in german patent document DE102015014382, it is described that the device for detecting the measured value i is a sensor device 25 which is configured as a grating, i.e. comprises a light source 26 and a light receiver 27. The optically active grating is blocked by the looped yarn of the linear rotating outer diameter B, in the exemplary embodiment the outer yarn 5 originating from the first feeding bobbin 7, intermittently blocking the light beam 28 during each revolution of the linear rotating outer diameter B, which enables to deduce the instantaneous rotation speed of the spindle 2 and the size of the linear rotating outer diameter B. How the dimensions of the wire-turning outer diameter B are determined is not given in the document. In german patent document DE102016001099, it is described that the sensor system 33 can be designed as a one-way grating, in which the light source 41 and the light receiver 40 are arranged on opposite sides of the outer diameter B of the yarn rotation to be monitored, or as a reflection grating, in which the light source 41 and the light receiver 40 are positioned on the same side of the outer diameter B of the yarn rotation to be monitored and are arranged, for example, in a common sensor housing. The measuring beam 42 of the sensor device 33 is thus intersected twice by the thread 25 at each revolution of the thread rotational outer diameter B. The control circuit 18 calculates the diameter of the current yarn outer diameter B of rotation without any problem on the basis of the time interval t of the two measuring pulses and the known distance of the measuring beam 42 from the axis of rotation 35 of the spindle 2. According to the scheme, the precision requirements on the sensing device 33 and the adjusting circuit 18 are very high, 10000 r/min is taken as an example, the time of one rotation of the yarn is about 6 milliseconds, the time required by one refreshing of the PLC is 100-200 milliseconds, the time difference between two pulses of 1-3 milliseconds needs to be detected within the time range of one rotation of 6 milliseconds, the precision requirements on the sensing device 33 and the adjusting circuit 18 are extremely high, the requirement on the anti-interference capability of equipment is extremely high, the cost of the equipment is higher, and the anti-interference capability is weaker.

when the count is 0, the tension adjusting device (4) reduces the tension of the yarn (5) at a larger adjusting speed, and after a period of time, if the count is still 0, the yarn is determined to be broken; if the count increases to 1, the tension adjusting device (4) continues to reduce the tension on the yarn (5) at a smaller adjusting rate until the count is 2;
when the diameter of the rotating ring (1) needs to be adjusted, the swing driving device (16) drives the rotating seat (21) to rotate for an angle, and the sliding seat (19) slides for a certain distance along the arc-shaped guide rail (18) until the rotating ring (1) is positioned between the first light beam (201) and the second light beam (31);
when the range between the oversize rotating outer diameter (101) and the undersize rotating outer diameter (103) needs to be adjusted, the photoelectric tube seat (11) and the reflection seat (14) are driven to rotate for an angle through the rotation driving device (20) until the requirements are met;
the diameter of the rotating ring (1) and the range between the over-large rotating outer diameter (101) and the under-small rotating outer diameter (103) need to be adjusted simultaneously, and the aforementioned steps are adjusted simultaneously.
