[0010] As a further embodiment of this utility model: a support base is fixedly connected to the bottom of the table, and a cutting groove is provided on the top of the workbench, the cutting groove being located below the cutting block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This cardboard box bending device consists of a base, a drive motor, a drive wheel, a driven wheel, a transmission wheel, a drive shaft, and a conveyor belt. When bending the cardboard box, the box is first placed between the drive wheel and the driven wheel in the base. The box then presses against the driven wheel, lifting it upwards. The driven wheel then drives the fixed shaft upwards, which in turn moves a slider upwards. The slider pulls a spring upwards, thus fixing the box and driving it forward. Next, the drive motor in the motor box is turned on and rotated, which in turn drives the drive shaft to rotate. This drives the transmission wheel and the drive wheel to rotate, further driving the box forward. Finally, the transmission wheel drives the conveyor belt to rotate, transporting the box to the top of the workbench. This device is suitable for cardboard boxes of varying thicknesses, improving user convenience and reducing labor costs.

[0013] 2. This cardboard box bending device consists of a worktable, a cutting groove, a connecting plate, a cutting block, and a bending block. When bending is required, the cardboard box is first moved to the top of the worktable and passes under the cutting and bending blocks. An electric telescopic rod applies downward pressure to the bending block, causing it to engage with the bending groove on the top of the worktable to bend the cardboard. Then, the pressure on the bending block is released, allowing it to move upward. A punch cylinder then applies downward pressure to the connecting plate, causing it to move downward. The connecting plate then moves the cutting block downward, allowing it to engage with the cutting groove on the top of the worktable to cut the cardboard. The cardboard box is then removed from the top of the worktable, thus improving the efficiency of cardboard box bending. Attached Figure Description

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a cardboard box bending device, including a table 1, a workbench 2 fixedly connected above the table 1, and a frame 5 fixedly connected to the top of the workbench 2. Because of the frame 5, the stamping cylinder 17 and the electric telescopic rod 22 can be fixed by setting the frame 5.

[0020] A base 3 is fixedly connected to the top of the table 1, and a support 6 is fixedly connected to the bottom of the table 1. A cutting groove 20 is provided on the top of the workbench 2. The cutting groove 20 is located below the cutting block 19. By setting the cutting groove 20, the carton can be cut by the cooperation between the cutting groove 20 and the cutting block 19.

[0021] Limiting grooves 23 are provided on both sides of the base 3. Two sliders 24 are slidably connected in the limiting grooves 23. A spring 16 is provided between the two sliders 24. A drive shaft 7 is engaged on one side of one of the sliders 24. A drive wheel 8 is provided on the outside of the drive shaft 7. A fixed shaft 9 is fixedly connected to one side of one of the sliders 24. The fixed shaft 9 is located above the drive shaft 7. A driven wheel 10 is provided on the outside of the fixed shaft 9. An auxiliary plate 15 is provided between the two drive wheels 8. By providing the auxiliary plate 15, it is possible to prevent the carton from tilting downwards at one end during transmission, thereby affecting the direction of the carton transmission. The two ends of the auxiliary plate 15 are fixedly connected to... Inside the base 3, a transmission wheel 11 is fixedly connected to one end of the transmission shaft 7, and a transmission belt 12 is sleeved on the outside of the transmission wheel 11. A drive motor 13 is fixedly connected to one end of one of the transmission shafts 7, and a motor box 14 is fixedly connected to the outside of the drive motor 13. One end of the motor box 14 is fixedly connected to one side of the base 3. Electric telescopic rods 22 are fixedly connected to both ends of the bottom of one side of the frame 5. A bending block 21 is fixedly connected to the bottom of the electric telescopic rod 22. Because of the electric telescopic rod 22, the bending block 21 can be pressed downward by the electric telescopic rod 22, so that the bending block 21 and the bending groove 4 cooperate with each other to bend the carton.

[0022] The top of the workbench 2 is provided with a bending groove 4, which is located below the bending block 21. Because of the bending groove 4, it is convenient to bend the carton.

[0023] A stamping cylinder 17 is fixedly connected to both ends of the bottom of one side of the frame 5. A connecting plate 18 is fixedly connected to the bottom of the stamping cylinder 17. A cutting block 19 is fixedly connected to the bottom of the connecting plate 18. Because of the stamping cylinder 17, the connecting plate 18 can be pressed downward by the stamping cylinder 17, causing the connecting plate 18 to move downward. Then, the cutting block 19 is moved downward by the connecting plate 18. Thus, the carton is cut by the cooperation between the cutting block 19 and the cutting groove 20.

[0024] The working principle of this utility model is as follows: When it is necessary to bend the carton, firstly, the carton is placed between the drive wheel and the driven wheel 10 in the base 3. Then, the carton will squeeze the driven wheel 10, thereby lifting the driven wheel 10 upward. The driven wheel 10 drives the fixed shaft 9 to move upward, the fixed shaft 9 drives the slider 24 to move upward, and the slider 24 drives the spring 16 to pull upward, thereby fixing the carton and driving it forward. Then, the drive motor 13 in the motor box 14 is turned on and rotated. The drive motor 13 drives the transmission shaft 7 to rotate, and the transmission shaft 7 drives the transmission wheel 11 and the transmission wheel 8 to rotate, thereby driving the carton forward. The transmission wheel 11 then drives the conveyor belt 12 to rotate. The carton is then moved to the top of the workbench 2 and passes under the cutting block 19 and bending block 21. The electric telescopic rod 22 applies downward pressure to the bending block 21, causing the bending block 21 to cooperate with the bending groove 4 on the top of the workbench 2 to bend the carton. Then, the pressure of the electric telescopic rod 22 on the bending block 21 is released, causing the bending block 21 to move upward. The stamping cylinder 17 then applies downward pressure to the connecting plate 18, causing the connecting plate 18 to move downward. The connecting plate 18 then drives the cutting block 19 to move downward, thereby cutting the carton by cooperating with the cutting groove 20 on the top of the workbench 2. The carton is then removed from the top of the workbench 2.
