Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0084] Combination Figure 5 , Figure 8 and Figure 9 The working mechanism of the fabric storage device in this utility model is as follows:

[0085] The process requires unwinding mode. Operate the 3-position rotary switch S28-2 to the unwinding mode label position. One end of rotary switch S28-2 is connected to the PLC input terminal X2, and the other end is connected to N24. PLC output terminals Y18 and Y16 are energized. Y16 controls K17, K17 controls KM2, and KM2 controls the magnetic powder brake. The magnetic powder driver adjusts the tension of the magnetic powder controller. When the material production is complete, the operator needs to change the shaft. The operator presses the unwinding and cloth storage button and the push-button switch S42. One end of rotary switch S42 is connected to the PLC input terminal X31, and the other end is connected to N24. PLC output terminals Y21 and Y23 are energized. Y21 controls K2 to be energized, K2 controls KM3 to be energized, and KM3 controls the hydraulic station motor to be energized; Y23 controls K4 to be energized, and K4 controls the hydraulic station lifting solenoid valve to be energized. The hydraulic station oil outlet continuously supplies oil to the lifting cylinder through the high-pressure oil pipe, and the lifting cylinder begins to rise and drives the lifting roller to rise through the transmission chain. When the operator completes the shaft changing work, the operator activates the unwinding and lowering button and the push-button switch S44. One end of the push-button switch S44 is connected to the input terminal X34 of the PLC and the other end is connected to N24. The output terminal Y21 of the PLC is de-energized and the hydraulic station motor is disconnected from the work, and Y20 is energized. Y20 controls the energization of the pressure roller solenoid valve and the descent of the pressure roller via intermediate relay K1. K1 energizes the pressure roller solenoid valve and causes the pressure roller to descend. Simultaneously, the hydraulic station's oil outlet valve Y21 is de-energized. The fabric storage device descends by gravity while maintaining constant tension. When the fabric storage device touches the lower limit switch S35, one end of the limit switch S35 is connected to the PLC input terminal X10, and the other end is connected to N24. When the limit switch S35 opens, it indicates that there is no material in the fabric storage device. The PLC output terminals Y23 and Y20 are de-energized, as are the hydraulic station's rising solenoid valve and pressure roller solenoid valve, causing the pressure roller to return to its original position. The single-cycle unwinding and rewinding operation is completed.

[0086] The process requires the winding mode. Operate the 3-position rotary switch S28-1 to the winding mode label position. One end of the rotary switch S28-1 is connected to the PLC input terminal X1, and the other end is connected to N24. The PLC output terminal Y31 is energized, which in turn energizes K8. K8 controls the forward rotation of the winding inverter. The winding inverter speed is controlled by connecting the normally closed auxiliary contacts K13-1 and K13-2 to the PLC's analog 0-10V signal. Potentiometer R2 adjusts the winding inverter torque, indirectly adjusting the material tension. When the winding head is fully wound, the operator needs to change the roll. The operator presses the winding and storing cloth button S41. One end of the button switch S41 is connected to the PLC input terminal X34, and the other end is connected to N24. When PLC outputs Y21 and Y23 are energized, Y21 controls K2, K2 controls KM3, and KM3 controls the hydraulic station motor; Y23 controls K4, which in turn controls the hydraulic station's lifting solenoid valve. The hydraulic station's oil outlet continuously supplies oil to the lifting cylinder via a high-pressure oil pipe. The lifting cylinder begins to rise and, via the transmission chain, drives the lifting roller upwards. After a few seconds of logic control, PLC output Y20 is energized, which controls K1. K1 controls the pressure roller solenoid valve and causes the pressure roller to descend. When the operator completes the shaft change, they activate the winding and lowering button switch S43. One end of button switch S43 is connected to PLC input X33, and the other end is connected to N24. When the PLC output Y21 and the hydraulic station motor lose power, the lifting roller of the fabric storage device descends by gravity and maintains constant tension. When the fabric storage device touches the lower limit switch S35, one end of the limit switch S35 is connected to the PLC input X10, and the other end is connected to N24. When the limit switch S35 opens, it means there is no material in the fabric storage device. The PLC outputs Y23 and Y20 lose power, the hydraulic station's lifting solenoid valve and pressure roller solenoid valve lose power, and the pressure roller returns to its original position. The winding shaft is in the winding operation, and a single winding cycle is completed. In addition, in the winding mode, for easier and faster roll changing, a speed and torque mode switching function and a winding linkage / single action function are configured. The operator operates the rotary switch S39 to the winding speed mode on the operation label. One end of the rotary switch S39 is connected to the PLC input X15, and the other end is connected to N24. When the PLC output terminal Y35 is energized, Y35 controls K12 and K13 to be energized. K12-1 receives the COM port of the winding inverter at one end and the X8 port of the winding inverter at the other end. When the X8 port of the winding inverter is set to open for speed mode and closed for torque mode, K12 is closed, the X8 port is in the on state, and the inverter is in speed mode. The normally open auxiliary contacts K13-3 and K13-4 are closed, and the speed of the winding shaft is indirectly adjusted by adjusting the frequency of the inverter through potentiometer R1.

[0087] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
