Abstract
The invention discloses a control method for a yarn ballooning size of a straight twisting machine, and belongs to the technical field of textile machinery. The problems that external yarn tension control is not accurate, and an optimum ballooning shape cannot be reached exist in the existing straight twisting machine. The straight twisting machine is characterized in that an external yarn sensor is arranged in a yarn path between a twisting tray and an external yarn tensioner and used for detecting an external yarn linear speed and yarn tension; a strand yarn sensor is arranged in a yarn path between an overfeeding device and an even twisting device and used for detecting a strand yarn linear speed and tension; or/and a motor sensor is arranged on a spindle drive motor and used for detecting a motor speed and motor current; the external yarn tensioner is driven by a separate motor to feed yarns actively; an overfeeding wheel of the overfeeding device is driven by a separate motor; and by taking one, two or three detection results of the three sensors as separate or combined control parameters, a control system controls a speed of the motor connected with the overfeeding wheel, adjusts a strand yarn pulling speed, and ensures that an external yarn tension value meets a requirement of the optimum yarn ballooning shape capable of allowing a wrapping angle to be minimum.

The motor speed that state modulator processed is connected with overfeeding wheel changes.
On the basis of outer yarn sensor is set, setting electromechanical transducer detection electricity on described spindle motor simultaneously
Any one or two in machine rotating speed and two parameters of current of electric detect simultaneously, yarn sensor beyond described control system
The testing result of testing result and electromechanical transducer is arbitrarily made with the electricity that at least two control parameter controls are connected with overfeeding wheel
Machine rotating speed changes.
On the basis of outer yarn sensor and stock yarn sensor are set, motor is arranged on described spindle motor simultaneously
Sensor detects that any one or two in motor speed and two parameters of current of electric detect simultaneously, described control system
Can beyond yarn sensor testing result, the testing result of stock yarn sensor and electromechanical transducer testing result combination in any
At least three control parameters are become to control the motor speed being connected with overfeeding wheel to change.
Described outer yarn tensioner is by single Motor drive uniform rotation active line sending.
The motor that described outer yarn tensioner connects is by yarn speed, outer yarn tension, spindle motor beyond control system
