[0032] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0033] Example 1: Please refer to Figure 1-5 As shown, this embodiment provides a batch cutting device, including a base 1, with a workbench 2 fixedly mounted on the top of the base 1. Two side plates 3 are fixedly mounted on the top of the workbench 2, forming a processing groove between the two side plates 3 for stacking multiple cardboard pieces to be cut.

[0034] A fixing frame 4 is installed above the processing groove, and the fixing frame 4 is fixedly connected to the top of both side plates 3. A second cylinder 7 is fixedly installed on the top of the fixing frame 4. One end of the piston rod of the second cylinder 7 slides through the inner wall of the top of the fixing frame 4 and is fixedly installed with an L-shaped mounting plate 8. A cutting blade 9 is fixedly installed on the bottom of the L-shaped mounting plate 8 for edge trimming of the stacked cardboard.

[0035] To ensure the stability of the cardboard during the cutting process, this embodiment also includes a pressing assembly. The pressing assembly includes a movable plate 11 disposed on one side of the L-shaped mounting plate 8. Multiple guide rods 13 slide through the bottom of the movable plate 11, and a single pressure plate 15 is fixedly mounted at the bottom end of each guide rod 13. A first spring 14 is fitted onto the outer wall of each guide rod 13; one end of the first spring 14 is fixedly connected to the top of the pressure plate 15, and the other end is fixedly connected to the bottom of the movable plate 11. Through the elastic force of the first spring 14, the pressure plate 15 can press and fix the stacked cardboard.

[0036] To adjust the height of the pressing assembly to accommodate cardboard of different thicknesses, in this embodiment, two limiting frames 10 are fixedly installed on one side of the L-shaped mounting plate 8, and the movable plate 11 is slidably connected to the inner walls of the two limiting frames 10. An adjusting screw 12 is also rotatably connected to one side of the L-shaped mounting plate 8 via a bracket, and the movable plate 11 is threadedly connected to the adjusting screw 12. By rotating the adjusting screw 12, the movable plate 11 can be adjusted up and down, thereby ensuring that the first spring 14 can adapt to stacked cardboard of various thicknesses.

[0037] To remove the waste strips after cutting, this embodiment also includes a pull plate assembly. A groove 16 is formed on one side of the base 1, and a groove that mates with the groove 16 is formed on one side of the worktable 2. A pull plate 19 is slidably connected inside the groove, and two fixing rods 20 are fixedly mounted on the bottom of the pull plate 19 via protrusions. Two sliding holes 17 are formed on one side of the worktable 2, and the two fixing rods 20 are slidably connected to the inner wall of the corresponding sliding hole 17. Limiting blocks 18 are fixedly installed on both sides of the inner wall of the groove, and one end of each of the two fixing rods 20 slides through the corresponding limiting block 18. A fixing collar 21 is fixedly sleeved on the outer wall of each of the two fixing rods 20, and the two fixing collars 21 are located between adjacent sliding holes 17 and limiting blocks 18. A second spring 22 is sleeved on the outer wall of each of the two fixing rods 20, one end of the second spring 22 is fixedly connected to one side of the fixing collar 21, and the other end is fixedly connected to one side of the limiting block 18. The pull plate 19 can be reset by the elastic force of the second spring 22. Both limit blocks 18 cooperate with the pull plate 19 to ensure that there is a gap between the pull plate 19 and the worktable 2 for the cutting blade 9 to pass through.

[0038] To facilitate the pushing of stacked cardboard, in this embodiment, a pusher plate 6 is provided in the processing groove. The pusher plate 6 is slidably connected to two adjacent side plates 3, and its bottom is slidably engaged with the top of the worktable 2. A first cylinder 5 is fixedly installed on the top of the worktable 2. The first cylinder 5 is located in the processing groove, and one end of its piston rod is fixedly connected to one side of the pusher plate 6. By pushing out the piston rod of the first cylinder 5, the pusher plate 6 can be pushed, thereby pushing the stacked cardboard toward the cutting blade 9 for cutting.

[0039] This application can be used in the field of packaging box production technology, or in other fields applicable to this application.

[0040] Example 2: Reference Figure 1 , 5 An improvement based on Example 1: a batch cutting device for packaging box production, which is applied to the field of packaging box production technology;

[0041] To facilitate the pulling out of the pull plate 19, in this embodiment, a push-pull block 23 is fixedly installed at the bottom of the pull plate 19, and the push-pull block 23 is located on the side away from the cutting blade 9. The user can easily pull out the pull plate 19 by operating the push-pull block 23, thereby discharging the cut waste strips.

[0042] To ensure the safety of the cutting operation, in this embodiment, a control switch 24 is fixedly installed on one side of each of the two side plates 3, and the two control switches 24 are connected in series. The user needs to press both control switches 24 simultaneously to control the piston rod of the second cylinder 7 to extend, thereby performing the cutting operation. This design can effectively prevent misoperation and improve the operational safety of the equipment.

[0043] However, as is well known to those skilled in the art, the working principles and wiring methods of the first cylinder 5, the second cylinder 7, and the control switch 24 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0044] The usage process and working principle of this utility model technical solution are as follows:

[0045] In use, the user can stack multiple cardboard sheets to be processed together, and then place them in the processing slot, ensuring that one side of each cardboard sheet is in close contact with the push plate 6. Next, the first cylinder 5 is activated, which pushes the push plate 6 to move within the processing slot. The push plate 6 moves the multiple cardboard sheets synchronously, moving their other edges below the cutting blade 9. Depending on the size of the packaging box cardboard, the user can control the push plate 6 to move to a suitable position relative to the cutting blade 9. Then, the user can simultaneously press two control switches 24 to activate the second cylinder 7. The design of the two control switches 24 ensures that the cutting blade 9 will not cause injury to the user due to accidental operation. When the second cylinder 7 drives the L-shaped mounting plate 8 to descend, the pressure plate 15 descends synchronously with the cutting blade 9, and the pressure plate 15 contacts the cardboard before the cutting blade 9. After the pressure plate 15 contacts the cardboard, as the L-shaped mounting plate 8 continues to descend, multiple guide rods 13 slide relative to the moving plate 11, and at this time... A spring 14 is compressed to ensure that the pressure plate 15 can continuously press against the multiple cardboard pieces below. Depending on the thickness of the stacked cardboard pieces below, the user can also rotate the adjusting screw 12 to fine-tune the height of the moving plate 11, thereby ensuring that the pressure plate 15 has appropriate pressing force on stacked cardboard pieces of different thicknesses. As the L-shaped mounting plate 8 descends, the cutting blade 9 can cut the edge of the cardboard. Then, the second cylinder 7 retracts the piston rod again, and both the cutting blade 9 and the pressure plate 15 can rise sequentially. Next, the user can pull the pull plate 19 through the push-pull block 23. At this time, multiple cut strips of paper located above the pull plate 19 can fall into the inclined groove 16 through the gap between the pull plate 19 and the worktable 2, and be discharged along the inclined surface of the inclined groove 16. When the user stops pulling the pull plate 19, the pull plate 19 can quickly return to its original position under the action of the two second springs 22. At this time, it can be used with the push plate 6 to remove multiple cut cardboard pieces, and then rotate them to cut them again on the other side or put in new cardboard pieces for cutting.
