[0019] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0020] like Figure 1-Figure 3 As shown, a honeycomb paperboard punching and demoulding device includes a punching component and a demoulding component. The punching component includes a support frame 1, a punching cylinder 2, a pressing plate 3 and a cutting knife 4. The support frame 1 serves as an integral supporting structure component to provide installation support for each component.
[0021] Guide columns 5 are respectively arranged at the four corners of the support frame 1, and the pressing plate 3 is slidably mounted on the guide columns 5, and the pressing plate 3 can move up and down along the guide columns 5.
[0022] The support frame 1 is provided with a punching cylinder 2 for driving the pressing plate 3 to move. After the punching cylinder 2 is ventilated, it can drive the pressing plate 3 to move up and down on the guide pillar 5. A cutting knife 4 is provided under the pressing plate 3. When the pressing plate 3 is pressed down, the cutting knife 4 can punch the honeycomb paperboard.
[0023] The demoulding assembly includes a demoulding cylinder 6 and a demoulding template 7. The demoulding cylinder 6 is arranged on the pressing plate 3, and the demoulding template 7 is arranged under the piston rod of the demoulding cylinder 6. The demoulding template 7 is provided with a knife hole 8 that can cooperate with the cutter 4. The demoulding template 7 is surrounded by the outer side of the cutter 4. When part of the cardboard is stuck with the knife, the demoulding cylinder 6 is ventilated, and the demoulding template 7 moves downward, which can push the cardboard off the cutter 4 to realize the demoulding function.
[0024] Furthermore, the support frame 1 includes a base plate 9, the guide columns 5 are fixedly installed at the four corners of the base plate 9, a top plate 10 is provided at the upper end of the guide column 5, the punching cylinder 2 is installed on the top plate 10, a through hole 11 is opened in the middle of the top plate 10, and the piston rod of the punching cylinder 2 passes through the through hole 11 and is connected to the pressure plate 3 using a connecting seat 12.
[0025] Furthermore, mounting holes 13 are respectively opened at the four corners of the pressure plate 3, and copper sleeves 14 that can cooperate with the guide pillars 5 are respectively arranged in the mounting holes 13. The pressure plate 3 moves up and down on the guide pillars 5 by utilizing the cooperation between the copper sleeves 14 and the guide pillars 5, thereby improving the service life.
[0026] Furthermore, the stripping cylinder 6 is connected to the pressure plate 3 by means of a connecting flange 15. After the piston rod of the stripping cylinder 6 passes through the pressure plate 3, it is connected to the stripping template 7 by means of a fixing seat 16. The fixing seat 16 enables the stripping cylinder piston rod to be firmly connected to the pressure plate 3, thereby preventing the stripping template 7 from falling off during operation.
[0027] Furthermore, a clearance hole 17 that can cooperate with the stripping cylinder 6 is opened on the top plate 10. When the stripping cylinder 6 runs to the uppermost end at the pressing plate 3, it can pass through the clearance hole 17 without touching the top plate 10.
[0028] Furthermore, reinforcing ribs 18 are cross-arranged on the pressing plate 3 , and the reinforcing ribs 18 make the pressing plate 3 stronger and able to withstand a greater load.
[0029] Furthermore, the number of the stripping cylinders 6 is 4, and the 4 stripping cylinders 6 are symmetrically arranged on the pressing plate 3, so that the stripping template 7 moves up and down synchronously without tilting, thereby avoiding stripping jams.
[0030] Working principle: The utility model sets a guide column 5 between the bottom plate 1 and the top plate 10, and a pressing plate 3 is slidably set on the guide column 5, and a cutting knife 4 is set on the pressing plate 3. A stripping cylinder 6 is set on the pressing plate 3, and a stripping template 7 that can cooperate with the cutting knife 4 is set on the piston rod of the stripping cylinder 6. The stripping template 7 is driven by the stripping cylinder 6, so that the honeycomb paperboard stuck on the outside of the cutting knife 4 is pushed down to realize the stripping action, and then the stripping cylinder 6 retracts, and the next step of punching work can be continued.
[0031] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
