In this embodiment, the swing roller 332 has a normal operation station 2, a zero calibration station 1, and a full-scale calibration station 3. The cylinder is connected with the tension swing arm 331, and due to the thrust of the cylinder, the tension swing roller is stopped at the zero calibration station 1, and zero calibration needs to be performed on the tension controller at this time, as shown in fig. 1; swinging the tension swing arm 331 causes the swing roller 332 to reach the maximum position full scale calibration station 3, where a mechanical limit mechanism is disposed, as shown in fig. 3, at this time, the full scale calibration is performed on the panel of the tension controller, and the deviation generated in the installation and use process is eliminated through zero calibration and full scale calibration. In normal operation, under the action of the tension controller, the tension swing arm 331 controls the spindle motor 120 to stop the swing roller 332 at the normal operation station 2, so as to maintain a constant tension, as shown in fig. 2.
In this embodiment, as shown in fig. 4, the control device 340 includes a signal conditioning circuit 341, a CPU module 342, a subtraction circuit 343, a material axis servo motor driver 344, a TT L/RS 485 conversion module 345, a P L C module 346, a material receiving axis servo motor driver 347, and a control panel 348.

The tension control adopts a speed mode, when the real-time tension is greater than the set tension, the output voltage value is increased, the rotating speed of the material shaft is increased, and the tension is reduced at the moment; when the real-time tension is smaller than the set tension, the output voltage value is reduced, the rotating speed of the material shaft is reduced, and the tension of the system is correspondingly increased, so that the circulating operation is realized, and the automatic control is realized.
As shown in fig. 7, the tension PID processing is performed in the ADC interrupt routine service routine. The interrupt service routine carries out sliding filtering on the signal of the potentiometer type sensor; acquiring a current large and small volume signal through a photoelectric switch, and loading different PID parameters according to the volume diameter; judging the current state according to the current PID output trend, wherein the current state can be an acceleration stage, a deceleration stage and a constant speed stage, and different PID parameter correction values are made according to different stages; and the tension error value is used as an error signal, incremental PID calculation is carried out, the voltage of 0 to 5V is output, the voltage enters a peripheral subtraction circuit to be changed into the voltage of-2.5V to +2.5V, and the voltage is sent to a servo voltage controller, so that the aims of small deviation and quick system response are finally fulfilled.
