Detailed Description of the Preferred Embodiment

[0023] The present utility model will be further described below in conjunction with the drawings and embodiments. The implementation manners of the present utility model include but are not limited to the following embodiments.

[0024] Embodiment 1:

[0025] As Figures 1-4As shown in the figure, the carton creasing device for carton production and processing provided by the present utility model includes: a frame 1, on which two rollers 2 are installed. Two conveyor belts 3 are installed on the two rollers 2. The conveyor belts 3 are in a tensioned state. A creasing belt 9 is installed on the conveyor belts 3. One end of at least one roller 2 is connected to a driving motor, and the roller 2 is driven to rotate by the driving motor. Four limiting rings 4 are sleeved and installed on the roller 2. The four limiting rings 4 are respectively installed on both sides of the two conveyor belts 3. The limiting rings 4 abut against the sides of the conveyor belts 3 to limit the lateral position of the conveyor belts 3. The lateral position of the conveyor belts 3 and the creasing belt 9 can be adjusted by adjusting the axial position of the limiting rings 4 on the roller 2. A bearing roller 5 is installed on the frame 1. The bearing roller 5 is in contact with the inner side of the conveyor belt 3. An elevating rotating rod 6 is installed above the bearing roller 5. Two laterally adjustable roller pressing wheels 7 are installed on the rotating rod 6. The installation and driving methods of the rotating rod 6 and the roller pressing wheels 7 adopt the scheme disclosed in CN220500085U, which will not be elaborated here. During use, after adjusting the lateral position of the roller pressing wheels 7, the limiting rings 4 on both sides of the conveyor belt 3 are synchronously moved laterally, so that the creasing belt 9 on the conveyor belt 3 moves below the adjacent roller pressing wheels 7 until the lateral distance between the two reaches a suitable position. Then, the limiting rings 4 are fixed on the roller 2. The other creasing belt 9 moves below the other roller pressing wheel 7 and is used in cooperation with the roller pressing wheel 7. The carton is conveyed to the upper part of the bearing roller 5 through the two conveyor belts 3. The two roller pressing wheels 7 perform creasing operations on the top surface of the carton, while the two creasing belts 9 perform creasing operations on the bottom surface of the carton. Since the positions of the roller pressing wheels 7 and the creasing belts 9 can be adjusted laterally, they can be used in cooperation after adjustment, and the creasing positions on the upper and lower surfaces of the carton will not be inconsistent or mismatched.

[0026] By setting the frame 1 and the rollers 2, and installing two conveyor belts 3 on the two rollers 2, and using the limiting rings 4 installed on both sides of the conveyor belts 3, the lateral position of the creasing belt 9 can be adjusted. After adjustment, the creasing belt 9 can be used in cooperation with the two roller pressing wheels 7 above the bearing roller 5, and the creasing positions on the upper and lower surfaces of the carton will not be inconsistent or mismatched.

[0027] Embodiment 2:

[0028] As Figure 1 shown, width limiters 8 are installed on both sides of the frame 1. The width limiters 8 can limit the lateral position of the carton on the conveyor belt 3, so that the position of the carton that needs to be creased can be aligned with the roller pressing wheels 7 and the creasing belt 9, so that the carton can perform creasing operations according to the design.

[0029] By installing width limiters 8 on both sides of the frame 1 and using the two width limiters 8 in cooperation to limit the carton, the carton can perform creasing operations at the correct position.

[0030] Example 3:

[0031] As Figure 3 shown, a limit screw 10 is installed on the limit ring 4. The limit screw 10 penetrates through the limit ring 10. During use, the limit ring 10 is sleeved on the roller 2, and the limit screw 10 is rotated so that its bottom end tightly presses on the surface of the roller 2, then the limit ring 4 can be fixed on the roller 2. On the contrary, the limit ring 4 can be moved.

[0032] By installing the limit screw 10 on the limit ring 4, it is convenient to fix the limit ring 4 on the roller 2 for use.

[0033] Example 4:

[0034] As Figure 4 shown, the width limiting member 8 includes a track 11 installed on the frame 1. A laterally slidable slider 12 is installed on the track 11. A baffle 14 is installed on one side of the slider 12. The length of the baffle 14 can extend at least to the position of the pressure roller 5. And an adjusting knob 13 is installed on the top of the track 11 in a threaded manner. The bottom end of the adjusting knob 13 tightly presses on the slider 12. During use, the adjusting knob 13 is rotated to separate its bottom end from the slider 12, and then the baffle 14 can be pushed to make the slider 12 slide along the track 11 until the baffle 14 gently contacts the side of the carton that has been placed at a preset position on the conveyor belt 3. Then the adjusting knob 13 is rotated in the reverse direction to fix the slider 12 in the track 11, and further fix the position of the baffle 14 to limit the side of the carton. The width limiting member 8 on the other side is also processed in the same way to limit the other side of the carton. Therefore, after the carton is placed on the conveyor belt 3 between the two baffles 14, the position where the carton needs to be indented can be exactly aligned with the roller press wheel 7 and the indentation belt 9.

[0035] By setting the width limiting member 8 including the track 11, the slider 12, the adjusting knob 13 and the baffle 14, the side position of the carton can be limited, which is convenient for the carton to be indented at the correct position.

[0036] Example 5:

[0037] As Figure 4 shown, the baffle 14 is provided with a fold angle 15 on the side where the carton enters. The fold angle 15 is bent outward. Therefore, the distance between the entering sides of the two baffles 14 is greater than the width of the carton, so that the carton can smoothly enter between the two baffles 14, preventing the end of the baffle 14 from blocking or even piercing the carton.

[0038] By providing the fold angle 15 on one side of the baffle 14, it can prevent the end of the baffle 14 from blocking the carton, making it convenient for the carton to enter between the two baffles 14.

[0039] Working principle: When in use, after adjusting the lateral position of the roller press wheel 7, synchronously move the limit rings 4 on both sides of the conveyor belt 3 laterally, so that the indentation belt 9 on the conveyor belt 3 moves downward to the position below the adjacent roller press wheel 7 until the lateral distance between the two reaches a suitable position. Then fix the limit ring 4 on the roller 2. The other indentation belt 9 moves to the position below the other roller press wheel 7 and is used in cooperation with this roller press wheel 7. The cardboard box is conveyed to the upper part of the bearing roller 5 through the two conveyor belts 3. The two roller press wheels 7 perform indentation operations on the top surface of the cardboard box, while the two indentation belts 9 perform indentation operations on the bottom of the cardboard box. Since both the roller press wheel 7 and the indentation belt 9 can be adjusted laterally, therefore, the two can be used in cooperation after adjustment, and it will not cause the inconsistent or mismatched indentation positions on the upper and lower surfaces of the cardboard box.
