A frame 4 is fixedly installed in the inner cavity of the support frame 1. A tool body 5 that works with the stamping plate 7 is fixedly installed inside the frame 4. The output end of the first cylinder 6 drives the stamping plate 7 and the tool body 5 to perform die-cutting operations, ensuring the smooth progress of the die-cutting process. A knife groove 8 that works with the tool body 5 is provided on the lower surface of the stamping plate 7. The knife groove 8 works with the tool body 5 to precisely control the die-cutting position and shape, improving the die-cutting accuracy.

[0022] The support frame 1 and the upper surface of the stamping plate 7 are provided with a punching assembly 3 for use with the cutter body 5. The punching assembly 3 can discharge the waste material remaining after the cutter body 5 is punched in a timely manner. A demolding assembly 2 is provided on one side of the frame 4. The demolding assembly 2 can smoothly separate the punched honeycomb paperboard from the cutter body 5 after the punching is completed, reduce the damage to the paperboard during demolding, and improve the demolding effect.

[0023] The demolding assembly 2 includes a vertical groove 24, which is fixedly installed on one side of the frame 4. A servo motor 27 is fixedly installed on the lower surface of the vertical groove 24. A mounting base 26 for use with the servo motor 27 is fixedly installed on the lower surface of the frame 4. The servo motor 27 is fixedly installed in the mounting base 26, which provides a stable mounting position for the servo motor 27. The output end of the servo motor 27 passes through the vertical groove 24 and is fixedly connected to a screw 23, which facilitates the output end of the servo motor 27 to drive the screw 23 to rotate. A slider 25 is threaded on the outer surface of the screw 23. The slider 25 is slidably connected to the vertical groove 24. The rotation of the screw 23 causes the slider 25 to slide up and down in the vertical groove 24. The top end of the screw 23 is rotatably connected to the inner cavity of the vertical groove 24 to ensure the stability of the screw 23's rotation.

[0024] A stripping template 28 for use with the cutter body 5 is fixedly connected to one side of the slider 25. Guide blocks 22 are symmetrically fixedly connected to both sides of the stripping template 28. Guide grooves 21 for use with the guide blocks 22 are symmetrically opened in the inner cavity of the support frame 1. The guide blocks 22 and guide grooves 21 are slidably connected. The cooperation between the guide blocks 22 and guide grooves 21 can ensure the stability and accuracy of the stripping template 28 during movement. The stripping template 28 is slidably sleeved with the cutter body 5. The slider 25 drives the stripping template 28 to move. The stripping template 28 can lift the punched cardboard along the axial direction of the cutter body 5, which can better reduce the damage to the cardboard during demolding and improve the demolding effect.

[0025] The punching and purging assembly 3 includes a mounting bracket 36, which is fixedly mounted on the upper surface of the stamping plate 7. A second cylinder 37 is fixedly mounted on the upper surface of the mounting bracket 36. The output end of the second cylinder 37 passes through the mounting bracket 36 and is fixedly connected to a connecting plate 34. A connecting frame 38 is fixedly connected to the lower surface of the connecting plate 34. A plurality of punching and purging rods 31 are fixedly connected to the lower surface of the connecting frame 38. When the second cylinder 37 is working, it pushes the connecting plate 34, the connecting frame 38, and the punching and purging rods 31 to move downward. The punching and purging rods 31 move through the stamping plate 7. The punching and purging rods 31 are made of stainless steel and are positioned corresponding to the holes on the tool body 5. The stainless steel punching and purging rods 31, corresponding to the holes on the tool body 5, can quickly discharge the waste material stuck inside the tool body 5, replacing the traditional manual cleaning and saving time and effort.

[0026] The inner cavity of the support frame 1 is symmetrically provided with slots 32. A guide bar 35 is slidably connected in the slots 32. A collection basket 33 for use with the punching rod 31 is fixedly connected to one side of the opposite side of the guide bar 35. The damping sliding connection of the guide bar 35 can keep the collection basket 33 stable when collecting waste. The collection basket 33 is used to collect the waste that is punched down, which is convenient for centralized processing and effectively improves the efficiency of the honeycomb paperboard punching and demolding device.

[0027] Working principle: First, the honeycomb paperboard to be punched is placed on the cutter body 5. Then, the first cylinder 6 is started. When the first cylinder 6 is working, it pushes the punching plate 7 to move downward. Since the lower surface of the punching plate 7 is provided with a knife groove 8 that is used in conjunction with the cutter body 5, the punching plate 7 drives the knife groove 8 to cooperate with the cutter body 5 to punch the honeycomb paperboard, thereby completing the punching operation.

[0028] Next, the punching and discharge assembly 3 starts working. The second cylinder 37 in the punching and discharge assembly 3 is activated, pushing the connecting plate 34, the connecting frame 38 and the punching and discharge rod 31 to move downward. The punching and discharge rod 31 quickly discharges the waste material stuck inside the cutter body 5. After the waste material is discharged, it falls into the collection basket 33 for centralized collection.

[0029] Meanwhile, the guide bar 35 is damped and slidably connected in the slot 32, which facilitates the installation and disassembly of the collection basket 33 and ensures the stability of the collection basket 33 when collecting waste.

[0030] After the blanking is completed, the first cylinder 6 drives the stamping plate 7 to move upward, thus canceling the stamping of the cardboard.

[0031] Then, the demolding assembly 2 starts working, the servo motor 27 starts, and its output end drives the screw 23 to rotate. As the screw 23 rotates, the slider 25 slides upward in the vertical groove 24, and the demolding template 28 moves upward along the axial direction of the cutter body 5 under the drive of the slider 25, lifting the punched honeycomb paperboard from the cutter body 5 to realize the demolding operation.

[0032] Meanwhile, the guide block 22 is slidably connected to the guide groove 21, which ensures the stability and accuracy of the demolding template 28 during the movement process, avoids the demolding template 28 from shaking, better completes the demolding task, and reduces damage to the honeycomb paperboard.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
