[0027] In this embodiment, the threads on the front and rear sides of the outer wall of the screw rod 11 are arranged relative to each other, so that when the screw rod 11 rotates, the front and rear sides of its outer wall generate relative thread rotation force, so that the two sliders 13 slide relatively at the same time under the limiting action of the limiting groove 16 and the limiting block 17.

Before the use process, the sensor needs to be placed in a suitable position manually. However, there is a certain error in the manual placement of the sensor. When the inner side of the U-shaped groove is placed too close to the foil surface, the foil surface will be torn, but the sensor will not output an alarm, thereby affecting the normal operation of the foil machine. After adjusting the depth of the copper foil penetrating into the inner cavity of the photoelectric sensor 1, the turntable 12 is rotated to make the turntable 12 drive the screw rod 11 to rotate, so that the opposite threads on the front and rear sides of the outer wall of the screw rod 11 generate relative thread rotation force, so that the two sliders 13 are in the limit groove 16 and the limit Under the limiting action of the block 17, they slide toward the front and rear ends of the screw rod 11 at the same time, so that the two connecting rods 15 pull the fixing seat 14 and the limiting plate 3 to slide along a straight line toward the left side of the inner cavity of the photoelectric sensor 1 under the limiting action of the connecting block 10 and the connecting groove 9, so that the limiting plate 3 is kept away from the copper foil to avoid the copper foil from being scratched and torn between the limiting plate 3 during the movement. The knob 8 is rotated to drive the screw rod 7 to rotate. Since the screw rod 7 is screwed to the inner cavity of the fixing tube 6, when the screw rod 7 rotates, the transmitter and receiver 4 can slide up and down to adjust the distance between the two transmitter and receivers 4, so that the distance between the two transmitter and receivers 4 can be conveniently adjusted according to the actual usage situation, thereby improving the flexibility of the device when in use.
