[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a fixed plate, an adjusting groove, and a graduated groove, allows the fixed plate to move downwards via a movable plate. The fixed plate, in turn, moves the mounting sleeve, movable rod, and pressing plate. The pressing plate then contacts the carton to be cut, and a pressure spring applies pressure to it, preventing uneven cutting and ensuring a smooth slitting process. A movable baffle moves an adjusting block, which, in conjunction with the adjusting groove, allows for lateral adjustment of the baffle. This adjustment of the baffle effectively blocks the carton from being cut, ensuring proper slitting. This design facilitates subsequent slitting. The movement of the baffle moves the connecting plate, which in turn moves the pointer. The pointer then points to the scale groove, allowing for easy adjustment of the baffle's position and effective slitting of the packaging carton. This solves the problem that die-cutting machines without a pressing mechanism typically require manual positioning and fixing of the material, significantly increasing production time. Furthermore, die-cutting machines without an adjustment mechanism require repeated manual positioning and adjustment during packaging paper die-cutting, further increasing production time and reducing overall efficiency. This design provides the advantage of pressing and positioning the packaging paper during slitting.

[0015] 2. This utility model uses pressing components set on the left and right sides of the moving plate. The moving plate moves downward, driving the fixed plate to move. The fixed plate moves downward, driving the mounting sleeve, movable rod and pressing plate to move. The pressing plate moves and comes into contact with the packaging carton that needs to be cut. The pressure spring generates a thrust to press the pressing plate, so that the pressing plate can press the packaging carton and avoid the packaging carton from being too thin, which would result in poor cutting effect.

[0016] 3. This utility model uses an adjustment component set inside the mounting plate to move the baffle, which in turn moves the adjustment block. The movement of the adjustment block, in conjunction with the adjustment groove, allows for lateral adjustment of the baffle. This baffle adjustment then acts as a divider for the packaging cartons that need to be cut, thereby aligning the cartons for easier subsequent cutting. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, this utility model provides a die-cutting machine for producing food packaging cartons, including a workbench 1, a gantry frame 2, and a slitting blade 3. The gantry frame 2 is fixedly installed on the top of the workbench 1, and the slitting blade 3 is movably installed on the bottom of the inner wall of the gantry frame 2.

A movable plate 5 is movably installed on the bottom of the inner wall of the gantry frame 2, and the bottom of the movable plate 5 is fixedly connected to the top of the slitting blade 3. Pressing components 6 are provided on the left and right sides of the movable plate 5. Adjustment components 7 are provided on the inner side of the mounting plate 4. A control plate 8 is fixedly installed on the top of the front of the gantry frame 2.

[0023] refer to Figure 1 and Figure 2 The pressing assembly 6 includes a fixed plate 61, a mounting sleeve 62, a movable rod 63, a pressure spring 64, and a pressing plate 65. The fixed plate 61 is fixedly installed on the left and right sides of the movable plate 5. The mounting sleeve 62 is fixedly installed at the bottom of the fixed plate 61. The movable rod 63 is movably installed inside the mounting sleeve 62. The pressure spring 64 is fixedly installed at the top of the movable rod 63 and located inside the mounting sleeve 62. The pressing plate 65 is fixedly installed at the lower end of the movable rod 63.

[0024] As a technical optimization of this utility model, the pressing components 6 are set on the left and right sides of the moving plate 5. The moving plate 5 moves downward, driving the fixed plate 61 to move. The fixed plate 61 moves downward, driving the mounting sleeve 62, the movable rod 63 and the pressing plate 65 to move. The pressing plate 65 moves and comes into contact with the packaging carton that needs to be cut. The thrust generated by the pressure spring 64 applies pressure to the pressing plate 65, so that the pressing plate 65 can press the packaging carton and avoid the packaging carton from being too thin, which would result in poor cutting effect.

[0025] refer to Figure 1 and Figure 3 The adjustment assembly 7 includes an adjustment groove 71, an adjustment block 72, and a baffle 73. The adjustment groove 71 is opened inside the mounting plate 4. The adjustment block 72 is movably installed inside the adjustment groove 71. The baffle 73 is movably installed inside the mounting plate 4. The outer side of the baffle 73 is fixedly connected to the inner side of the adjustment block 72.

[0026] As a technical optimization of this utility model, by using the adjustment component 7 set inside the mounting plate 4, the baffle 73 is moved so that the baffle 73 drives the adjustment block 72 to move. The movement of the adjustment block 72 cooperates with the adjustment groove 71 to adjust the baffle 73 laterally. The adjustment of the baffle 73 blocks the packaging cartons that need to be cut, thereby aligning the packaging cartons to facilitate subsequent cutting.

[0027] refer to Figure 1 and Figure 3 The front mounting plate 4 has a scale groove 9 on its front side. The scale groove 9 has several sets of slits that are evenly distributed. A connecting plate 10 is fixedly installed on the top front side of the mounting plate 4. A pointer 11 is fixedly installed on the bottom of the connecting plate 10.

[0028] As a technical optimization of this utility model, the scale groove 9 set on the front of the mounting plate 4 is used to move the connecting plate 10 by moving the baffle 73, and the pointer 11 is moved by moving the connecting plate 10. The pointer 11 moves to point to the scale groove 9, thereby facilitating the adjustment of the position of the baffle 73 and effectively cutting the packaging carton.

[0029] refer to Figure 1 and Figure 3 A material collection hopper 12 is fixedly installed on the left side of the workbench 1. A guide groove 13 is opened on the top left side of the workbench 1. The left side of the guide groove 13 is connected to the material collection hopper 12. A guide plate 14 is fixedly installed on the top right side of the workbench 1, and two sets are provided.

[0030] As a technical optimization of this utility model, the hopper 12 set on the left side of the workbench 1 facilitates the initial alignment of the packaging cartons to be cut by the guide plate 14. The waste material of the packaging cartons after cutting falls into the hopper 12 through the guide groove 13 for collection.

[0031] refer to Figure 1 , Figure 2 and Figure 3 The bottom of the gantry frame 2 is fixedly equipped with a hydraulic cylinder 15 and two sets are provided. The output end of the hydraulic cylinder 15 is fixedly connected to the top of the moving plate 5. The top of the worktable 1 is provided with a slitting groove 16, and the inside of the slitting groove 16 is movably connected to the bottom of the slitting knife 3.

[0032] As a technical optimization of this utility model, a hydraulic cylinder 15 is set at the bottom of the gantry 2. The output end of the hydraulic cylinder 15 pushes the moving plate 5 to move. The moving plate 5 drives the slitting knife 3 to move. The slitting knife 3 moves and cooperates with the slitting groove 16 to slitting the packaging carton on the top of the workbench 1.

[0033] refer to Figure 1 and Figure 2 A control button 17 is fixedly installed on the front of the control panel 8, and a display panel 18 is fixedly installed on the front of the control panel 8 and located on top of the control button 17. The hydraulic cylinder 15 is electrically connected to the control button 17 and the display panel 18 through wires.

[0034] As a technical optimization of this utility model, the hydraulic cylinder 15 is raised and lowered by the control panel 8 set on the front of the gantry frame 2 and the control button 17, so that the hydraulic cylinder 15 can drive the moving plate 5 and the slitting knife 3 to move and slit the packaging carton.

[0035] The working principle and usage process of this utility model are as follows: During use, the guide plate 14 facilitates the initial alignment of the packaging cartons to be cut. The moving baffle 73 causes the adjusting block 72 to move. The adjusting block 72, in conjunction with the adjusting groove 71, adjusts the baffle 73 laterally. The baffle 73 then blocks the packaging cartons to be cut. The control button 17 controls the lifting and lowering of the hydraulic cylinder 15. The output end of the hydraulic cylinder 15 pushes the moving plate 5 to move, which in turn moves the cutting blade 3. The downward movement of the moving plate 5 moves the fixed plate 61. The device moves downward via the fixed plate 61, which in turn moves the mounting sleeve 62, the movable rod 63, and the pressing plate 65. The pressing plate 65 moves to contact the packaging carton that needs to be cut, and the pressure spring 64 applies pressure to the pressing plate 65, allowing the pressing plate 65 to press the packaging carton. The moving plate 5 moves to move the slitting knife 3, which moves in conjunction with the slitting groove 16 to cut the packaging carton on the top of the workbench 1. The waste material from the packaging carton after cutting slides down the guide groove 13 into the collection hopper 12 for collection.

[0036] In summary, this die-cutting machine for food packaging cartons utilizes a fixed plate 61, an adjusting groove 71, and a graduated groove 9. The downward movement of the movable plate 5 moves the fixed plate 61, which in turn moves the mounting sleeve 62, the movable rod 63, and the pressing plate 65. The pressing plate 65 then contacts the cartons to be cut, and the pressure spring 64 applies pressure to it, preventing uneven cutting and ensuring a smooth cut. The movable baffle 73 moves the adjusting block 72, which, in conjunction with the adjusting groove 71, adjusts the baffle 73 laterally. The baffle 73 adjusts to block the packaging cartons that need to be cut, thereby aligning the cartons for subsequent cutting. The movement of the baffle 73 moves the connecting plate 10, which in turn moves the pointer 11, which in turn points to the scale groove 9. This allows for easy adjustment of the position of the baffle 73, effectively cutting the packaging cartons. This solves the problem that die-cutting machines without a pressing structure usually require manual positioning and fixing of materials, which greatly increases production time. Furthermore, die-cutting machines without an adjustment structure require repeated manual positioning and adjustment when die-cutting packaging paper, which also greatly increases production time and reduces overall production efficiency.
