On both the left and right sides of the mounting plate 1, two fixed plates 3 are fixedly connected. Between the two fixed plates 3, a rotating shaft 4 is rotatably connected. Outside both of the rotating shafts 4, rotating rollers 5 are fixedly sleeved. Around both of the rotating rollers 5, the same conveyor belt 6 is wound. On one of the fixed plates 3, a motor 7 is fixedly connected. The output end of the motor 7 is fixedly connected to the rotating shaft 4. Above the mounting plate 1, a U-shaped frame 8 is fixedly connected. On the U-shaped frame 8, a hydraulic telescopic device 9 is fixedly connected. The output end of the hydraulic telescopic device 9 is fixedly connected to a mounting seat 10. Below the mounting seat 10, a die-cutting knife 11 is fixedly connected. Between the U-shaped frame 8 and the mounting seat 10, an anti-offset mechanism is connected;
[0028] The anti-offset mechanism includes two extrusion plates 12 symmetrically and fixedly connected to the lower side of the mounting seat 10. On the vertical side walls of the U-shaped frame 8, two through holes are symmetrically opened, and sliding rods 13 are movably inserted into the through holes. At one end of the two sliding rods 13 located inside the U-shaped frame 8, the same anti-offset plate 14 is fixedly connected. On the opposite sides of the anti-offset plate 14 and the extrusion plates 12, chamfering treatments are made. At the end of the sliding rod 13 far from the anti-offset plate 14, a limit block 15 is fixedly connected. Between the limit block 15 and the U-shaped frame 8, the same spring 16 is fixedly connected. The spring 16 is movably sleeved outside the sliding rod 13.
[0029] In this embodiment, during die-cutting, the cardboard is placed on the conveyor belt 6. The conveyor belt 6 conveys the cardboard to the lower side of the die-cutting knife 11. The hydraulic telescopic device 9 drives the mounting seat 10 to move downward. The mounting seat 10 drives the two extrusion plates 12 to move downward. The two extrusion plates 12 extrude the two anti-offset plates 14, causing the two anti-offset plates 14 to approach both sides of the cardboard. The two anti-offset plates 14 can limit both sides of the cardboard, thereby preventing the cardboard from shifting during die-cutting, effectively improving the die-cutting accuracy of the die-cutting device and effectively improving the forming quality of the packaging box.
[0030] On the U-shaped frame 8, two stripping ejector rods 17 are symmetrically and fixedly connected. On the upper side of the mounting seat 10, two jacks 18 are symmetrically opened. The stripping ejector rods 17 pass through the mounting seat 10 through the jacks 18. At the lower end of the stripping ejector rods 17, a push block 19 is fixedly connected.
[0031] In the above embodiment, during use, when die-cutting is completed, the hydraulic telescopic device 9 drives the die-cutting knife 11 to separate from the cardboard. When the cardboard stuck in the die-cutting knife 11 encounters the push block 19, the push block 19 can make the cardboard separate from the die-cutting knife 11, thereby avoiding the problem of inconvenient cardboard stripping after die-cutting and effectively improving the convenience of using the die-cutting device.
[0032] A same cross plate 20 is fixedly connected between the four support columns 2. Threaded holes 21 are formed in the cross plate 20.

The U-shaped plate 23 is slidably connected to the cross plate 20. A roller 24 is rotatably connected inside the U-shaped plate 23. The conveyor belt 6 is wound around the outside of the roller 24. During use, by rotating the adjusting screw rod 22, with the cooperation of the adjusting screw rod 22 and the threaded holes 21, the roller 24 can be driven to move, and the roller 24 drives the conveyor belt 6 to move, so that the tightness of the conveyor belt 6 can be adjusted, improving the smoothness of the operation of the conveyor belt 6.
[0033] A protective plate 25 is fixedly connected to the side of the anti-offset plate 14 away from the sliding rod 13. The specific material of the protective plate 25 is rubber. The provided protective plate 25 can prevent the anti-offset plate 14 from damaging the cardboard.
[0034] The lower end of the adjusting screw rod 22 is fixedly connected to a turntable 26. The outer wall of the turntable 26 is treated with anti-slip. The provided turntable 26 can improve the convenience of rotating the adjusting screw rod 22.
[0035] A triangular reinforcement plate 27 is fixedly connected between the side wall of the lower side of the cross plate 20 and the support column 2. The provided triangular reinforcement plate 27 can improve the stability of the connection between the cross plate 20 and the support column 2.
[0036] Two guide rods 28 are symmetrically and fixedly connected to the lower side of the U-shaped plate 23. Two guide grooves 29 are symmetrically formed in the cross plate 20. The two guide rods 28 are respectively movably inserted into the two guide grooves 29. The cooperation of the provided guide rods 28 and the guide grooves 29 can prevent the U-shaped plate 23 from rotating along with the adjusting screw rod 22.
[0037] A rubber pad 30 is fixedly connected to the lower side of the push block 19. The provided rubber pad 30 can prevent the push block 19 from causing indentations on the surface of the cardboard.
[0038] Working principle: During die-cutting, the cardboard is placed on the conveyor belt 6. The conveyor belt 6 conveys the cardboard to the lower part of the die-cutting knife 11. The hydraulic telescopic device 9 drives the mounting seat 10 to move downward. The mounting seat 10 drives the two pressing plates 12 to move downward. The two pressing plates 12 press the two anti-offset plates 14, causing the two anti-offset plates 14 to approach both sides of the cardboard. The two anti-offset plates 14 can limit both sides of the cardboard, thereby preventing the cardboard from shifting during die-cutting, effectively improving the die-cutting accuracy of the die-cutting device and effectively improving the forming quality of the packaging box.
