The second infrared distance measuring instrument 27 is located in the third installation groove 26.

[0023] This setting first determines the width of the plate to be punched, then rotates the threaded column 24 so that the threaded column 24 drives the limiting plate 25 to slide on the inner wall of the storage box 2. At the same time, the second infrared rangefinder 27 is used for distance measurement, so that the limiting plate 25 slides on the inner wall of the storage box 2 to an appropriate position. Then the plate is stacked between the two limiting plates 25. Then, the external controller is used to start the two electric push rods 16, so that the electric push rods 16 drive the two clamping plates 18 through the connecting blocks 17 respectively, and then the distance between the two clamping plates 18 is adjusted.

The controller receives the electrical signals transmitted by the first infrared rangefinder 19 and the second infrared rangefinder 27, and then the controller controls the opening and closing of the first motor 12, the electric push rod 16 and the second motor 21.

[0028] A placement groove 202 is formed in the inner side wall of the stock bin 2. The push block 23 is located in the placement groove 202 and is used to place the push block 23 to prevent the sheet from tilting due to the push block 23 when being placed.

[0029] Working principle: First, determine the width of the sheet to be punched. Then rotate the threaded column 24, and the threaded column 24 drives the limit plate 25 to slide on the inner wall of the stock bin 2. At the same time, use the second infrared rangefinder 27 to measure the distance. The limit plate 25 slides on the inner wall of the stock bin 2 to an appropriate position. Then stack the sheets between the two limit plates 25. Then use an external controller to start the two electric push rods 16. The electric push rods 16 respectively drive the two clamping plates 18 through the connecting blocks 17, and then adjust the distance between the two clamping plates 18. At the same time, use the first infrared rangefinder 19 to measure the distance. The distance between the two clamping plates 18 is equal to the distance between the two limit plates 25. Then use the controller to start the second motor 21. The second motor 21 drives the second threaded rod 22 to rotate.
