According to the independent arm splitting machine, through the mutual cooperation of the stations, tension on the diaphragm 700 can be detected and adjusted in real time, the diaphragm 700 is flattened, the diaphragm 700 is split, contact pressure on the split diaphragm 700 is adjusted, and splitting and winding quality and efficiency of the diaphragm 700 are improved greatly under the synergistic effect of the stations.
In an alternative aspect of this embodiment, the tension adjustment station 200 includes a detection roller assembly 210, an adjustment roller assembly 220, and a first drive assembly 230; the detection roller assembly 210 includes a tension roller 211 and a first detection element 212, wherein the first detection element 212 is disposed at an end of the tension roller 211 (preferably, the first detection element 212 is disposed at two ends respectively), and the first detection element 212 is fixedly mounted on the base; the adjusting roller assembly 220 comprises a floating roller 222 and a first swing arm 221, the first swing arm 221 is rotatably arranged on the base, the first swing arm 221 is in transmission connection with the output end of the first driving assembly 230, and the floating roller 222 is rotatably connected to the first swing arm 221; the first detection element 212 and the first driving component 230 are connected with a control device of the independent arm splitting machine; the first detecting element 212 can detect the tension of the diaphragm 700 on the tension roller 211, and transmit the detection result to the control device, and the control device controls the first driving assembly 230 to start, and the first driving assembly 230 drives the first swing arm 221 to rotate relative to the base, so as to adjust the position of the dancer 222.
In this embodiment, the specific working principle of the tension adjusting station 200 is: when the device is started, the first driving component 230 (preferably an air cylinder, hereinafter, when the principle is described, the first driving component 230 is assumed to be an air cylinder, when the first driving component 230 uses other structures, such as an electric cylinder, the principle is the same), the first driving component 230 acts with initial air pressure (the initial air pressure is calculated by tension calibration), the adjusting roller component 220 is pressed down, the position of the adjusting roller component 220 is detected by a potentiometer arranged at the end part of an adjusting rotating shaft of the adjusting roller component, the control device controls an unreeling motor in the unreeling station 100 to drive the unreeling roller to rotate according to the position fed back by the potentiometer, the unreeling roller pulls the diaphragm 700 so as to adjust the adjusting roller component 220 to the horizontal position, at the moment, the first detecting element 212 detects the tension value on the tension roller 211, and if the detected tension value is within a target range, the device starts to operate; if the detected tension value is not within the target range, the tension of the diaphragm 700 is adjusted by the rotation of the adjustment roller assembly 220 by adjusting the air pressure of the first driving assembly 230 (air cylinder) by adjusting the electric proportional valve, and thus the pressure value at the tension roller 211. The adjustment of the tension set point by adjusting the electric proportional valve is a dynamic adjustment process: adjusting the electrical proportional valve to further change the output of the first driving assembly 230, at this time, the tension of the diaphragm 700 and the position of the adjusting roller assembly 220 are both changed, the unreeling motor is controlled to rotate so as to adjust the position of the adjusting roller assembly 220 to the horizontal position, then it is judged whether the tension detected by the first detecting element 212 is within the target range, if yes, the adjustment is ended, the device starts to operate, if not, the adjustment is continued by adjusting the electrical proportional valve until the tension value detected by the first detecting element 212 is within the target range under the horizontal position of the adjusting roller assembly 220, the adjustment is completed, and the device starts to operate.
In this embodiment, by using the dancer assembly 220, the effect of tension disturbances of the diaphragm 700 on slitting may be reduced because the dancer assembly 220 may cushion by swinging as the diaphragm 700 is disturbed.
After the apparatus starts to operate, if the tension of the diaphragm 700 is changed, the dancer roller assembly 220 passively rotates to compensate the tension, so that the dancer roller assembly deviates from the horizontal position, and after the control device obtains information about the deviation from the horizontal position, the unreeling speed of the unreeling motor is controlled, so that the dancer roller assembly 220 is adjusted to the horizontal position. If the tension detected at the first detecting element 212 is within the target range when the dancer assembly 220 is adjusted to the horizontal position, the adjustment is completed, and if not, dynamic adjustment of the tension through the electric proportional valve and the first driving assembly 230 (air cylinder) is required.
Specifically, both ends of the tension roller 211 are rotatably connected to the first detecting element 212, the first detecting element 212 is fixed on the base, the diaphragm 700 bypasses the tension roller 211 to exert a force on the tension roller 211, at this time, the first detecting element 212 can detect the acting force and transmit the acting force to the control device, and the control device performs analysis and judgment to determine whether the detected value is within the target range. Further, when it is determined that the position of the floating roller 222 is not within the target range, the first driving assembly 230 is adjusted by adjusting the electric proportional valve, and the first swing arm 221 is driven to rotate on the base by the first driving assembly 230, at this time, the first swing arm 221 can synchronously drive the floating roller 222 to rotate, so that the position of the floating roller 222 is changed. Therefore, when the diaphragm 700 passes through the tension adjusting station 200, the tension on the diaphragm 700 can be detected and adjusted in real time, and the tension on the diaphragm 700 is continuously fed back and adjusted, so that the tension on the diaphragm 700 is finally kept within a preset range, the real-time control of the tension on the diaphragm 700 is realized, and the slitting quality of the diaphragm 700 is further improved. The control method/control process has the advantages of high control precision, high efficiency and the like.
