[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 and Figure 2 The utility model provides a box height automatic adjustment device used in a cardboard die-cutting and slotting machine, comprising a servo motor 1, a roller 2, a moving gear 20 on a shaft, a fixed gear 18 on a shaft, a hexagonal shaft 8 and a gear box 17.

[0022] like Figure 1 and Figure 2 The roller 2 is mounted on the driving shaft (shown in the figure, not numbered) of the servo motor 1, and the fixed gear 18 on the shaft is mounted on the end of the driving shaft; the movable gear 20 on the shaft is mounted on the driving shaft and is located between the roller 2 and the fixed gear 18 on the shaft. The servo motor 1 can drive the roller 2 to move through its driving shaft, so that it moves at a constant speed, accelerates, or decelerates.

[0023] like Figure 1 and Figure 2 , the roller 2 is provided with a tool holder 3, that is, the tool holder 3 is sleeved on the roller 2, a fixed knife 4 is installed on one side of the tool holder 3 for die-cutting cardboard, and a pinion 7, an adjustment large internal gear 6 and a moving knife 5 are arranged on the other side. The moving knife 5 is limited on the tool holder 3, and it can move relative to the fixed knife 4 within a circumferential range. Specifically, the pinion 7 is meshed with the adjustment large internal gear 6, and the adjustment large internal gear 6 is fixed to the moving knife 5; the pinion 7 is installed on the hexagonal shaft 8, and the hexagonal shaft 8 is arranged parallel to the driving shaft. The end of the hexagonal shaft 8 is provided with a first adjustment gear 9, and the first adjustment gear 9 is meshed with the moving gear 20 on the shaft. The hexagonal shaft 8 can rotate relative to the roller 2, or it can rotate together with the roller 2 when working. The hexagonal shaft 8 drives the pinion 7 to move, and the pinion 7 then turns the adjustment large internal gear 6 to rotate, so that the moving knife 5 changes its displacement, and the purpose of adjusting the box height can be achieved. The movable knife 5 is in an arc-shaped structure, and the adjusting large internal gear 6 is in an arc-shaped structure, which ensures that the effect of the movable knife 5 on the carton cutting will not change after displacement.

[0024] like Figure 1 and Figure 2, a planetary mechanism 14 with a small tooth difference is arranged in the gear box 17, and a servo reducer 15 is installed on the outside thereof. The planetary mechanism 14 with a small tooth difference is a prior art and will not be described here again. The servo reducer 15 is connected to the planetary mechanism 14 with a small tooth difference through a small shaft 16. That is, the small shaft 16 can transmit the power of the servo reducer 15 to the planetary mechanism 14 with a small tooth difference. A connecting shaft 13 is arranged on the planetary mechanism 14 with a small tooth difference, and the connecting shaft 13 is used to output power. The connecting shaft 13 is arranged parallel to the driving shaft, and a second adjustment gear 10 is installed on the end of the connecting shaft 13, and the second adjustment gear 10 is meshed with the moving gear 20 on the shaft; the planetary mechanism 14 with a small tooth difference is meshed with the fixed gear 18 on the shaft, that is, the planetary mechanism 14 with a small tooth difference can be rotated by the meshing of the fixed gear 18 on the shaft.

[0025] like Figure 1 and Figure 2 In this preferred embodiment, a wall panel 11 is further included, the gear box 17 is installed on one side of the wall panel 11, the fixed gear 18 on the shaft is located in the gear box 17, and the movable gear 20 on the shaft is located on the other side of the wall panel 11. A bearing seat 12 is provided on the wall panel 11, and the bearing seat 12 is used to support the connecting shaft 13. The tooth width of the movable gear 20 on the shaft is greater than the sum of the tooth widths of the first adjustment gear 9 and the second adjustment gear 10, ensuring that the effect of the two adjustment gears transmitting power through the gears is optimal.

[0026] Furthermore, the fixed gear 18 on the shaft is connected to the driving shaft through a spherical roller bearing 19, and the spherical roller bearing 19 is also provided on the wall panel 11. The fixed gear 18 on the shaft can rotate together with the drum 2 when the spherical roller bearing 19 is working.

[0027] During specific operation, the roller 2 starts to rotate under the drive of the servo motor 1, and the tool holder 3 also rotates with the rotation of the roller 2, so that the packaging cardboard to be formed can be die-cut; by using the servo motor 1, the die-cutting accuracy can be effectively controlled to ensure the processing quality of the product. When the packaging cardboard is die-cut normally (that is, no additional adjustment of the box height is required), the first adjustment gear 9 and the moving gear 20 on the shaft are relatively stationary, the servo reducer 15 does not work, and the planetary small tooth difference mechanism rotates with the fixed gear 18 on the shaft.

[0028] When the box height needs to be adjusted, the servo reducer 15 is started, the small shaft 16 rotates to drive the planetary small tooth difference mechanism to rotate, and the connecting shaft 13 rotates under the action of the planetary small tooth difference mechanism, thereby driving the second adjustment gear 10 to rotate, and the moving gear 20 on the axis meshing with it rotates accordingly, and the first adjustment gear 9 also rotates, and then drives the small gear 7 to rotate through the hexagonal shaft 8, and the small gear 7 thereby drives the large internal gear 6 to rotate, so that the position of the moving knife 5 changes, so that the size of its slot can be adjusted, and then the purpose of adjusting the box height is achieved. The automatic box height adjustment device used in the cardboard die-cutting slotting machine can adjust the box height when the entire equipment is moving or stopped. It is easy to use and does not need to be stopped for adjustment, which can effectively improve production efficiency.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
