[0024] The side length detection component 3 includes a fixed box 301 installed on the side wall of the square column 2. An activity plate 302 is slidably installed inside the fixed box 301. A first limit plate 303 is installed on the activity plate 302, and the first limit plate 303 is used to contact and limit the side wall of the corrugated board. One end of the activity plate 302 located inside the fixed box 301 is installed with a first position sensor 308, and the first position sensor 308 is used to measure the distance between one end of the activity plate 302 away from the first limit plate 303 and the base 1. A sliding groove is opened on the side wall of the fixed box 301. A slider 304 is fixedly installed on one side wall of the activity plate 302 located at the fixed box 301. The slider 304 is slidably connected with the sliding groove. Two fixed plates 305 are symmetrically arranged on both sides of the slider 304. The two fixed plates 305 are fixedly installed on the fixed box 301. A screw rod 306 is rotatably installed between the two fixed plates 305. The screw rod 306 is threadedly connected with the slider 304. One end of the screw rod 306 is fixedly connected with the output shaft of the motor 307, and the motor 307 is fixedly installed on the fixed plate 305. The fixed boxes 301 are installed on two perpendicular side walls of the square column 2. The long side and the wide side of the corrugated board are respectively contacted with the two fixed boxes 301. The motor 307 is used to move the activity plate 302 until the first limit plates 303 on the two activity plates 302 respectively contact the other two sides of the corrugated board. The length and width of the corrugated board are automatically detected through the first position sensor 308 and the length of the activity plate 302.

[0025] The thickness detection component 4 includes a longitudinal activity groove opened inside the base 1. A longitudinal plate 401 is movably installed inside the longitudinal activity groove. A second limit plate 402 is fixedly installed at the top end of the longitudinal plate 401, and the second limit plate 402 is used to limit the top wall of the corrugated board. A second position sensor 406 is installed on one side wall of the longitudinal plate 401 located at one end inside the longitudinal activity groove, and the second position sensor 406 is used to measure the distance between the bottom end of the longitudinal plate 401 and the upper surface of the base 1. Two springs 403 are symmetrically installed at the bottom end of the longitudinal plate 401. The bottom ends of the springs 403 are fixedly connected with the inner bottom wall of the longitudinal activity groove. A magnetic block 404 is fixedly installed at the bottom end of the longitudinal plate 401. An electromagnet 405 is fixedly installed on the inner bottom wall of the longitudinal activity groove. When the electromagnet 405 is energized, it generates an attractive force on the magnetic block 404, causing the longitudinal plate 401 to move downward until the second limit plate 402 contacts the top wall of the corrugated board. The thickness of the corrugated board is automatically detected through the second position sensor 406 and the length of the longitudinal plate 401. When the thickness of the corrugated board is small, the thickness of a single corrugated board is detected by measuring the thicknesses of multiple corrugated boards of the same size, which is convenient for use.

[0026] Working principle: During operation, first place the corrugated cardboard to be measured on the top of the base 1, such that the two perpendicular sides of the corrugated cardboard are respectively in close contact with the two fixed boxes 301. Turn on the motor 307 to make the screw 306 rotate. Since the screw 306 is threadedly connected to the slider 304, the movable plate 302 is driven to move horizontally until the first limiting plates 303 at the ends of the two movable plates 302 contact the other two sides of the corrugated cardboard. At this time, the distance between the end of the movable plate 302 and the square column 2 is detected by the first position sensor 308, and the detection result is A, while the length of the movable plate 302 is B. Thus, the length or width of the corrugated cardboard can be obtained as A + B;

[0027] Then control the electromagnet 405 to be energized to generate an attractive force on the magnetic block 404, thereby driving the longitudinal plate 401 to move downward until the second limiting plate 402 contacts the top wall of the corrugated cardboard. The second position sensor 406 detects the distance between the bottom end of the longitudinal plate 401 and the base 1, and the detection result is C, while the length of the longitudinal plate 401 is D. Thus, the thickness of the corrugated cardboard can be obtained as C + D. When the thickness of the corrugated cardboard is small, place n corrugated cardboard of the same size on the base 1, and the thickness can be obtained as C + D / n.
