the cylinder control end is connected with the output end of the adjustment controller;
further comprises:
after the adjustment controller sends motor driving information to the paper roll motor control interface, initial tension values of tension sensors on the first adjustment roller and the second adjustment roller are obtained;
the adjustment controller judges whether the difference value between the initial tension value and an initial preset value is within a set initial threshold value, if not, the initial adjustment tension is obtained according to the initial tension value and the initial preset value; acquiring an initial adjustment length according to the initial adjustment tension and a preset corresponding relation between the tension and the paper path length;
the adjusting controller drives the adjusting roller cylinder according to the initial adjusting length, so that the telescopic rods of the first adjusting roller and the second adjusting roller can drive the first adjusting roller and the second adjusting roller to slide along the extending direction of the frame body until the initial tension value is adjusted to the position closest to the initial preset value.
2. The fully automatic reel of claim 1, wherein the adjustment controller is further configured to determine whether the pressure value of the pressure sensor is less than a set point, and if so, to generate the paper change information.
3. The fully automatic reel of claim 1, wherein the adjustment controller is further configured to obtain a centrifugal offset distance of the current raw material reel according to the sensing information of the plurality of position sensors, and obtain an average position corresponding to the periodic centrifugal offset distance of the raw material reel within a set number of turns; obtaining an output distance corresponding to the average position;
when the adjustment controller drives the motor control end to make corresponding driving according to the initial driving information, or when the adjustment controller drives the motor control end to make corresponding driving according to the intermediate driving information, judging whether the adjusted distance is an output distance, and if not, generating paper relaxation information.
