[0030] Specific implementation in this embodiment: The above-mentioned conveying device 1, photoelectric switch 4, and counter 5 are all well-known in the art for counting. The conveying device 1 is used to convey the produced cardboard. The counter 5 is equipped with a microcomputer control circuit. When a cardboard moves past the photoelectric switch 4 on the conveying device 1, the grating on the photoelectric switch 4 generates a pulse signal. The pulse signal is transmitted through the connecting wire to the microcomputer control circuit in the counter 5. The microcomputer control circuit counts the number of cardboard through the counter 5. When it is necessary to count the cardboard, the carrier 2 is installed on the upper part of the tail end of the conveying device 1 through the fixing unit 3. The photoelectric switch 4 is installed at the lower end of the mounting post 6. The position of the mounting post 6 along the carrier 2 is adjusted through the first adjustment unit 7 to avoid the cardboard cutting seam position. At the same time, the height of the photoelectric switch 4 is adjusted through the second adjustment unit 8 to improve the accuracy of the photoelectric switch 4 in identifying the number of cardboard. At the same time, the counter 5 is installed in the carrier plate 9 through the limiting unit 10, and the photoelectric switch 4 and the counter 5 are electrically connected by wires. Then the conveying device 1 can be started to convey the cardboard, and the number of cardboard is monitored through the counter 5 and the photoelectric switch 4. When the counter 5 monitors that the number of cardboard is sufficient for packing, the microcomputer control circuit in the counter 5 transmits the signal to the external main controller. The external main controller controls the conveying device 1 to stop and clears the displayed number of the counter 5. When the cardboard at the tail end of the conveying device 1 is transferred, the conveying device 1, the photoelectric switch 4, and the counter 5 are started again to improve the accuracy of counting the cardboard.

[0031] Embodiment Two

[0032] Please refer to Figure 2 and Figure 6 This embodiment includes the above-mentioned embodiment. The fixing unit 3 includes adjusting bolts 11 that penetrate and are threadedly connected to both ends of the carrier 2. Rotating connection plates 12 are respectively connected to the opposite ends of the two adjusting bolts 11. A first limiting nut 13 for limiting the adjusting bolt 11 is threadedly connected to the side of the adjusting bolt 11.

[0033] Specific implementation in this embodiment: When it is necessary to install the carrier 2, move the carrier 2 above the conveying device 1. By rotating the two adjusting bolts 11, the two rotating connection plates 12 are driven to be clamped on the opposite sides of the conveying device 1. The rotating connection plate 12 is L-shaped. After tightening the adjusting bolts 11, the carrier 2 will not move down due to vibration. Tighten the first limiting nut 13 to limit and fix the position of the adjusting bolt 11. The carrier 2 can be installed on conveying devices 1 with different widths, improving the applicability of the overall device.

[0034] Embodiment Three

Among them, the first adjustment unit 7 includes a sliding block 14 slidably connected within the carrier 2, and a mounting post 6 is provided on the sliding block 14. A sliding groove 15 adapted to the sliding block 14 is formed through the upper side of the carrier 2. A first threaded post 16 is fixedly connected to the upper side of the sliding block 14, and a second limit nut 17 is threadedly connected to the side of the first threaded post 16. The second adjustment unit 8 includes a third limit nut 18 threadedly connected to the side of the mounting post 6. The mounting post 6 passes through the first threaded post 16 and the sliding block 14, and the mounting post 6 is threadedly connected to the first threaded post 16 or the sliding block 14. Through holes 24 are formed through the upper and lower ends of the mounting post 6. One end of the photoelectric switch 4 is provided with a second threaded post 25, and the second threaded post 25 is threadedly connected within the through hole 24.

[0036] Specific implementation method in this embodiment: When installing the photoelectric switch 4, the connecting wire is passed out through the through hole 24, and the photoelectric switch 4 is installed between the mounting post 6 by threadedly connecting the second threaded post 25 within the through hole 24. When it is necessary to adjust the photoelectric switch 4 along the length direction of the carrier 2, the sliding block 14 slides within the sliding groove 15. When the sliding block 14 moves, it drives the mounting post 6 to move, thereby driving the photoelectric switch 4 to move along the sliding groove 15. After the horizontal position of the photoelectric switch 4 is adjusted, the second limit nut 17 threadedly connected to the side of the first threaded post 16 is tightened to limit and fix the position of the sliding block 14. When it is necessary to adjust the height position of the photoelectric switch 4, the height position of the photoelectric switch 4 can be adjusted by rotating the mounting post 6 threadedly connected in the middle of the sliding block 14. After the position adjustment is completed, the position of the mounting post 6 is limited and fixed by tightening the third limit nut 18, which is convenient for adjusting the position of the photoelectric switch 4.

A bidirectional lead screw 22 with one end extending into the moving groove 21 is passed through the side of the carrier plate 9. The bidirectional lead screw 22 passes through both moving blocks 20 and is threadedly connected to the moving blocks 20. A fourth limit nut 23 is threadedly connected to the side of the end of the bidirectional lead screw 22 located outside.

[0039] Specific implementation method in this embodiment: Place the counter 5 in the carrier plate 9, which is located between two clamping frames 19. By rotating the bidirectional lead screw 22, the threads on the side of the bidirectional lead screw 22 are symmetrically arranged in the reverse direction. When the bidirectional lead screw 22 rotates, it drives two moving blocks 20 to move towards each other in the moving grooves 21. The two moving blocks 20 drive the two clamping frames 19 to clamp and fix the counter 5. Subsequently, tighten the fourth limit nut 23 to limit and fix the position of the bidirectional lead screw 22, which is convenient for installing and fixing the counter 5.
