[0023] When the polarizing plate needs to be cut, the polarizing plate in roll is installed on the winding wheel 4, then the one end of the polarizing plate is pulled out manually and passes through the gap at the bottom of the limiting plate 102, so that the one end of the polarizing plate is located in the front and rear clamping mechanism, then the polarizing plate is clamped by the clamping mechanism, the hollow piston rod 71 of the second air cylinder 7 is pulled to pull the clamping mechanism away from the winding wheel 4, at the same time, the winding wheel 4 rotates to release the polarizing plate, in the process of the hollow piston rod 71 retracting into the second air cylinder 7, the clamping mechanism contacts and extrudes the fixed block 9, the first elastic member 81 is stretched, the sliding rod 8 gradually moves away from the inside of the hollow piston rod 71, when the hollow piston rod 71 is completely retracted into the second air cylinder 7, the sliding rod 8 is still in the inside of the hollow piston rod 71, then the cutter 6 is driven by the first air cylinder 5 to move downward to cut the polarizing plate, after cutting, the clamping mechanism is loosened, the cut polarizing plate is moved to the right by the belt conveyor 2 and falls into the discharging frame 3, then the clamping mechanism is reset by the second air cylinder 7, the uncut polarizing plate is clamped again, and the above steps are repeated to continuously cut the polarizing plate, when the size of the polarizing plate needs to be adjusted, the first bevel gear 14 is rotated by the handle, so that the second bevel gear 15 drives the screw rod 13 to rotate, so that the fixed plate 12 slides along the hollow piston rod 71 away from the transmission assembly, so that when the hollow piston rod 71 is retracted into the second air cylinder 7, the distance between the clamping mechanism and the second air cylinder 7 is reduced, so that the distance between the cutter 6 and the clamping mechanism is increased, so that longer polarizing plates can be cut, when shorter polarizing plates need to be cut, the screw rod 13 can be reversed by the transmission assembly, the moving distance of the fixed plate 12 can be accurately adjusted according to the scale on the scale 22, so that the required size of the polarizing plate can be accurately cut, the cutting efficiency of the polarizing plate is improved, the limiting plate 102 can reduce the height of the polarizing plate when it is pulled out, so that the polarizing plate can be kept horizontal when it is cut, and the error rate of the cutting size of the polarizing plate is reduced.
