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.

[0025] Please see Figure 1-7 This utility model provides a technical solution:

[0026] A corrugated paper cutting device for corrugated box production includes: a mounting frame 1, and a first cutting mechanism 3, a material transfer mechanism 5, and a second cutting mechanism 6 arranged sequentially along the corrugated paperboard conveying direction, all of which are installed within the mounting frame 1; and multiple sets of clamping mechanisms 4, which are symmetrically arranged in pairs on both sides of the first cutting mechanism 3 and the second cutting mechanism 6 for clamping the corrugated paperboard during cutting.

[0027] In an optional embodiment: such as Figures 1 to 3 As shown, it also includes a fixing plate 2, which is fixedly connected to the inner wall of the mounting frame 1. The first cutting mechanism 3 includes a cylinder 31, a push plate 32, a cutting blade 33, and a positioning rod 34. The cylinder 31 is fixedly installed on the top of the fixing plate 2, and the telescopic end of the cylinder 31 is fixedly installed on the top of the push plate 32. The cutting blade 33 is fixedly installed on the bottom of the push plate 32, and the positioning rod 34 is fixedly connected to the top of the push plate 32. The positioning rod 34 is movably inserted into the fixing plate 2.

[0028] It should be noted that the cylinder 31, the push plate 32 and the cutting knife 33 work together. The cylinder 31 pushes the push plate 32, so that the cutting knife 33 approaches the corrugated cardboard and cuts the corrugated cardboard into segments.

[0029] In an optional embodiment: such as Figure 4 As shown, the pressing mechanism 4 includes a support rod 41, a pressure roller frame 42, a pressure roller 43, a mounting rod 44, and a tension spring 45. The support rod 41 is fixedly installed on the inner wall of the mounting frame 1, the pressure roller frame 42 is rotatably installed on the support rod 41, and the pressure roller 43 is movably installed inside the pressure roller frame 42.

[0030] The mounting rod 44 is fixedly installed on the inner wall of the mounting frame 1. One end of the pull spring 45 is movably installed on the mounting rod 44, and the other end of the pull spring 45 is movably installed on the pressure roller frame 42 for dragging the pressure roller frame 42 so that the pressure roller 43 presses against the corrugated cardboard.

[0031] It should be noted that the support rod 41, pressure roller frame 42, pressure roller 43, and mounting rod 44 work together to press the corrugated cardboard, avoiding dimensional deviations and rough edges caused by displacement, and ensuring the quality of the initial cutting.

[0032] Specifically, when the corrugated cardboard passes through the pressure roller 43, the corrugated cardboard lifts the pressure roller 43, and under the drag of the pressure roller frame 42 by the pull spring 45, the pressure roller 43 presses against the corrugated cardboard, pressing and fixing the corrugated cardboard.

[0033] In an optional embodiment: such as Figure 5 As shown, the material transfer mechanism 5 includes a guide rail 51, a slider 52, an electric slide table 53, a moving plate 54, a connecting rod 55, and a vacuum suction cup 56. The guide rail 51 is fixedly installed on one side of the mounting frame 1, the electric slide table 53 is fixedly installed on the other side of the mounting frame 1, the slider 52 is slidably installed on the guide rail 51, the moving plate 54 is fixedly installed on the slide base of the slider 52 and the electric slide table 53, the connecting rod 55 is fixedly installed on the bottom of the moving plate 54, and the vacuum suction cup 56 is fixedly installed on the bottom of the connecting rod 55.

[0034] The mounting bracket 1 has a movable slot 9, and the movable plate 54 is slidably installed in the movable slot 9.

[0035] It should be noted that the guide rail 51, slider 52, electric slide table 53, moving plate 54, connecting rod 55 and vacuum suction cup 56 work together to transport the corrugated cardboard, realize the stacking of multiple sets of corrugated cardboard, use the interaction force between the cardboard to assist in fixation, and prepare for secondary cutting.

[0036] The guide rail 51 and the slider 52 work together to guide and position the moving plate 54, so that the corrugated cardboard can be stably transported by the transfer mechanism 5.

[0037] A vacuum suction cup 56 is connected to a vacuum hose, which is connected to a vacuuming device. The vacuuming device uses the vacuum hose to create a vacuum in the vacuum suction cup 56, allowing the corrugated cardboard to be attached to the connecting rod 55 via the vacuum suction cup 56.

[0038] In an optional embodiment: such as Figure 6 As shown, the second cutting mechanism 6 includes a drive motor 61, a rotating rod 62 and a cutting blade 63. The drive motor 61 is fixedly installed on the side of the mounting frame 1. The output shaft of the drive motor 61 is fixedly connected to the rotating rod 62 through a coupling. The cutting blade 63 is fixedly installed on the cutting blade 63.

[0039] It should be noted that the drive motor 61, the rotating rod 62 and the cutting blade 63 work together to cut the corrugated cardboard.

[0040] In an optional embodiment: such as Figure 1 and Figure 2 As shown, a first belt conveyor 7 and a second belt conveyor 8 for conveying corrugated cardboard are fixedly installed on the inner bottom of the mounting frame 1.

[0041] It should be noted that the first belt conveyor 7 and the second belt conveyor 8 work together to convey the corrugated cardboard.

[0042] Additionally, a support base 11 is fixedly installed at the bottom inner side of the mounting frame 1. The support base 11 is located between the first belt conveyor 7 and the second belt conveyor 8, and is located directly below the cutting blade 33. The top of the support base 11 is provided with a clearance groove for the cutting blade 33 to avoid. The cutting blade 33 serves to support the corrugated cardboard and prevent the cutting position from being recessed when the cutting blade 33 cuts the corrugated cardboard.

[0043] In an optional embodiment: such as Figure 2 As shown, it also includes multiple sets of stops 10 fixedly installed at the bottom of the mounting frame 1 for positioning the corrugated cardboard during transport.

[0044] It should be noted that the stop block 10 is used to position the corrugated cardboard box and prevent the corrugated cardboard from shifting when it is conveyed on the first belt conveyor 7 and the second belt conveyor 8, which would affect the cutting quality of the corrugated cardboard.

[0045] The usage process of this utility model is as follows: Corrugated cardboard is conveyed on the first belt conveyor 7 and the second belt conveyor 8. When it passes the pressing mechanism 4 of the first cutting mechanism 3, the pressure roller 43 can press the corrugated cardboard onto the first belt conveyor 7 to press and fix the first belt conveyor 7, so as to avoid dimensional deviation and edge roughness caused by displacement and ensure the quality of the first cut.

[0046] After the corrugated cardboard moves below the first cutting mechanism 3, the cylinder 31 is activated. The telescopic rod of the cylinder 31 pushes the push plate 32, causing the cutting blade 33 to approach the corrugated cardboard and cut it. The electric slide table 53 is activated, and the electric slide table 53 drives the moving plate 54 to move. The moving plate 54 drives the vacuum suction cup 56 to tilt downward and approach the corrugated cardboard. The vacuuming equipment evacuates the vacuum suction cup 56, allowing the corrugated cardboard to be adsorbed onto the vacuum suction cup 56. The electric slide table 53 is activated again, and the electric slide table 53 drives the vacuum suction cup 56 to move through the moving plate 54, allowing the corrugated cardboard to be dragged by the transfer mechanism 5 to move above another set of corrugated cardboard. The vacuuming equipment stops evacuating the vacuum suction cup 56, allowing the corrugated cardboard to be pressed on top of another set of corrugated cardboard, achieving multiple stacking. The interaction force between the cardboard pieces is used to assist in fixing, and at the same time, it prepares for secondary cutting.

[0047] When the corrugated cardboard is conveyed close to the second cutting mechanism 6, it is further reinforced and fixed by the clamping mechanism 4 close to the second cutting mechanism 6 to ensure stable precision when cutting strips. The drive motor 61 drives the rotating rod 62 to rotate the cutting blade 63, so that the cutting blade 63 can cut the corrugated cardboard into strips. The cut strips are then conveyed and unloaded by the second belt conveyor 8.

[0048] The control method in this application is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so the control method and circuit connection will not be explained in detail. The device is powered by a built-in power supply or an external power supply.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
