Description

Technical Field

[0001] This utility model relates to the field of crimping machine technology, specifically a slitting crimping machine for corrugated paper production. Background Technology

[0002] A slitting and creasing machine for corrugated paper production is a specialized piece of equipment in a corrugated board production line, primarily used for longitudinal cutting and creasing of corrugated board. It cuts corrugated board (such as A-flute, B-flute, C-flute, etc.) longitudinally (parallel to the corrugation direction) and presses crease lines (creases) onto the board. It is typically used to cut wide corrugated board into narrow strips and press fold lines for subsequent processing into components such as side panels and flaps of cartons.

[0003] During the slitting process, corrugated cardboard is fed into the slitting and creasing machine via a conveyor belt. The slitting blade cuts the cardboard longitudinally, dividing it into multiple narrow strips. If the corrugated cardboard is not centered during the production process, the slitting blade will not be aligned with the center of the cardboard, resulting in uneven cutting edges, increased dimensional deviations, and inaccurate cutting. Consequently, the carton size will not meet the design requirements, affecting the packaging effect. Therefore, it is necessary to provide a slitting and creasing machine that can position the corrugated cardboard to improve the accuracy of slitting and creasing. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a slitting and creasing machine for corrugated paper production, comprising:

[0028] The support base 11, the fixing frame 12, the corrugated paper 13, the lifting frame 14 and the rotating shaft 16 are arranged together. The fixing frame 12 is fixed on the upper surface of the support base 11. The corrugated paper 13 is placed on the upper surface of the support base 11. The lifting frame 14 is located inside the fixing frame 12. The rotating shaft 16 rotates through the interior of the lifting frame 14. The upper surface of the fixing frame 12 is fixed with a first electric push rod 15, and the output end of the first electric push rod 15 is connected to the lifting frame 14. A first motor 17 is fixed on one side of the rotating shaft 16. A pressure knife 18 passes through the outer surface of the rotating shaft 16.

[0029] The support base 11 serves as the basic support structure of the entire equipment, supporting the weight of the corrugated paper 13 and ensuring its stability during processing. The fixed frame 12 serves as the main frame of the equipment, used to install components such as the lifting frame 14 and the first electric push rod 15. Driven by the first electric push rod 15, the lifting movement is realized, thereby adjusting the pressure between the pressure knife 18 and the corrugated paper 13. The first motor 17 drives the pressure knife 18 to perform creasing or longitudinal cutting operations through the rotating shaft 16. The pressure knife 18 performs precise processing on the corrugated paper 13.

[0030] The positioning assembly includes a connecting frame 21, a limiting post 25, a movable plate 26, a connecting plate 27, and a positioning plate 29. The connecting frame 21 is fixed to one side of the fixed frame 12. Two limiting posts 25 are provided and fixed to the two sides inside the connecting frame 21 respectively. The movable plate 26 slides through the two sides of the limiting post 25. The connecting plate 27 is fixed below the movable plate 26. The positioning plate 29 is fixed to one side of the connecting plate 27.

[0031] The connecting frame 21 serves as the mounting base for the positioning component, and the limiting post 25 serves as the guide mechanism for the movable plate 26, limiting its range of motion and ensuring that the movable plate 26 moves in a straight line. The movable plate 26 is used to transmit the power of the second electric push rod 23. The connecting plate 27 drives the positioning plate 29 to move towards the center or both sides through the movement of the movable plate 26. The positioning plate 29 is used to contact the two sides of the corrugated paper 13 to achieve the centering positioning of the corrugated paper 13.

[0032] A fixed frame 22 is fixed on the upper surface of the connecting frame 21. A second electric push rod 23 is fixed inside the fixed frame 22. A lifting plate 24 is fixed at the output end of the second electric push rod 23. Movable slots 241 are opened on both sides of the lifting plate 24. A connecting column 28 is rotatably passed through the movable slot 241. The other end of the connecting column 28 is rotatably passed through the connecting plate 27. The positioning plate 29 contacts both sides of the corrugated paper 13.

[0033] The first electric push rod 15 is model DYT-1000, and the second electric push rod 23 is model DYT-50. The fixed frame 22 is used to install the second electric push rod 23. The second electric push rod 23 drives the lifting plate 24 to move up and down through telescopic movement, thereby driving the connecting column 28, the movable plate 26 and the positioning plate 29 to achieve the centering positioning of the corrugated paper 13.

[0034] Working principle:

[0035] When slitting and pressing the corrugated paper 13, simply place the corrugated paper 13 on the support base 11, and then start the second electric push rod 23 through the external controller. The second electric push rod 23 drives the lifting plate 24 to move upward. The lifting plate 24 simultaneously drives the upper end of the connecting column 28 to move upward, so that the lower end of the connecting column 28 pulls the connecting plate 27 to move towards the middle. The connecting plate 27 simultaneously drives the movable plate 26 to move towards the middle at the limiting column 25. The movable plate 26 and the connecting plate 27 drive the positioning plate 29 to move towards the middle. The positioning plate 29 contacts the corrugated paper 13 and positions the corrugated paper 13 in the middle of the surface of the support base 11.

[0036] This step uses the second electric push rod 23 to drive the lifting plate 24 and related moving parts to achieve automatic centering and positioning of the corrugated paper 13, ensuring that the cutting and creasing positions of the slitting blade and creasing wheel on the corrugated paper 13 are accurate, and improving the accuracy of operation.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The moving component includes a second motor 31, a lead screw 32, and a movable ring 33. The second motor 31 is fixed to one side of the fixed frame 12. The lead screw 32 is fixed to the output end of the second motor 31 and rotates through the inside of the fixed frame 12. The movable ring 33 slides through the outer surface of the lead screw 32. A telescopic rod 34 is fixed to the lower surface of the movable ring 33. A connecting rod 35 is fixed to one side of the telescopic rod 34, and one side of the connecting rod 35 is connected to the pressure knife 18.

[0039] The second motor 31 serves as the power source for the moving component, providing rotational power to drive the lead screw 32 to rotate. Through forward and reverse rotation control, the movable ring 33 moves left and right on the lead screw 32, thereby adjusting the spacing of the pressure knife 18. The telescopic rod 34 is used to support the connecting rod 35 and the pressure knife 18, and the connecting rod 35 is used to connect the pressure knife 18.

[0040] Working principle:

[0041] When adjusting the longitudinal cutting width, the second motor 31 is started, which drives the lead screw 32 to rotate. The rotation of the lead screw 32 synchronously drives the movable ring 33 to move on the outer surface of the lead screw 32, adjusting the spacing of the movable ring 33. The movable ring 33 synchronously drives the telescopic rod 34 to adjust, the telescopic rod 34 drives the connecting rod 35 to move, and the connecting rod 35 then drives the pressure knife 18 to adjust the spacing on the surface of the rotating shaft 16. When the telescopic rod 34 extends, the first electric push rod 15 extends synchronously, and the lifting frame 14 moves downward, causing the pressure knife 18 to move downward.

[0042] In this step, the second motor 31 drives the lead screw 32 to rotate, which in turn moves the movable ring 33 on the outer surface of the lead screw 32, thereby achieving precise adjustment of the spacing of the pressure knife 18. This not only improves the processing effect of longitudinal cutting and pressing of corrugated paper 13, but also reduces equipment maintenance costs and manual operation risks.
