[0001] This utility model relates to the technical field of cross-cutting tools, and in particular to a cardboard cross-cutting tool. Background Technology

[0002] As a basic material for the packaging, printing and logistics industries, the processing efficiency and precision of cardboard directly affect the production costs and product quality of downstream industries.

[0003] In the paperboard processing process, such as the prior art patent with authorization announcement number CN219946351U, this utility model discloses a paperboard cross-cutting machine that is easy to replace the blades, belonging to the field of paperboard cross-cutting machine technology. It includes a frame, a support frame is provided on the top of the frame, movable slots are provided on both sides of the support frame, and an electric hydraulic rod is fixedly installed on the top of the support frame.

[0004] However, during the use of the equipment, it was found that the main cutter was not very convenient to use when cutting multiple notches in different positions on the cardboard, which reduced processing efficiency and affected cutting accuracy. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cardboard cross-cutting knife that improves the flexibility of spacing adjustment, enhances ease of use, and improves the cutting quality of cardboard.

[0006] This utility model discloses a cardboard cross-cutting tool, including a fixed plate mounted on a device drive shaft; it also includes a drive structure, a first cutting blade, a second cutting blade, a third cutting blade, and a fourth cutting blade. The first cutting blade is fixedly mounted on the outer wall of the fixed plate. Drive structures are provided on both sides of the fixed plate. The second, third, and fourth cutting blades are respectively mounted on the drive structures, which drive the second, third, and fourth cutting blades to move circumferentially to different positions. The drive structures are mounted on the device drive shaft. By adjusting the circumferential positions of the second, third, and fourth cutting blades through the drive structures, the spacing between the first, second, third, and fourth cutting blades can be flexibly adjusted. When the cardboard is conveyed below the fixed plate, the device drive shaft drives the fixed plate and drive structures to rotate synchronously, causing the first, second, third, and fourth cutting blades to move synchronously circumferentially. This allows the cardboard to be cut with notches at different positions by the first, second, third, and fourth cutting blades during its movement, improving the flexibility of blade adjustment, enhancing ease of use, and improving the cutting quality of the cardboard.

[0007] Preferably, the drive structure includes two sets of first turntables, two sets of second turntables, two sets of third turntables, a first side plate, and a second side plate. The two sets of first turntables are rotatably mounted on both sides of the fixed plate, the two sets of second turntables are rotatably mounted on both sides of the two sets of first turntables, and the two sets of third turntables are rotatably mounted on both sides of the two sets of second turntables. A power unit is provided on the drive shaft of the equipment. The power unit is used to independently drive the rotation and adjustment of the two sets of first turntables, the two sets of second turntables, or the two sets of third turntables. A second cutting blade is mounted on the two sets of first turntables, a third cutting blade is mounted on the two sets of second turntables, and a fourth cutting blade is mounted on the two sets of third turntables. The first side plate is mounted on the equipment drive shaft and rotatably connected to the first set of third turntables. The second side plate is mounted on the equipment drive shaft and rotatably connected to the second set of third turntables. By driving the two sets of first turntables to rotate independently, the first turntables drive the second cutting blade to move circumferentially. By driving the two sets of second turntables to rotate independently, the two sets of second turntables drive the third cutting blade to move circumferentially. By driving the two sets of third turntables to rotate independently, the two sets of third turntables drive the fourth cutting blade to move circumferentially. This improves the ease of adjusting the spacing between the first, second, third, and fourth cutting blades and improves the ease of cutting notches at different positions on the cardboard.

[0008] Preferably, it also includes a blade head and an elastic pad. The blade head is installed at a certain angle on the outer wall of the first cutting blade, the second cutting blade, the third cutting blade and the fourth cutting blade, and the elastic pad is disposed inside the blade head. By pressing the blade head into contact with the cardboard, the blade head cuts a notch in the cardboard. The elastic pad pushes the cardboard embedded in the blade head outward, preventing the cardboard from getting stuck in the blade head and affecting the cutting.

[0009] Preferably, the device also includes multiple sets of threaded holes and multiple sets of bolts. The multiple sets of threaded holes are respectively set on the outer walls of the fixed plate, the two sets of first turntables, the two sets of second turntables, and the two sets of third turntables. The multiple sets of bolts are respectively set on the second cutting blade, the third cutting blade, and the fourth cutting blade, and the multiple sets of threaded holes and multiple sets of bolts are installed in conjunction. By setting multiple sets of threaded holes and multiple sets of bolts, the convenience of fixing the first cutting blade, the second cutting blade, the third cutting blade, and the fourth cutting blade in different positions is improved.

[0010] Preferably, it also includes serrations, which are set at the end of the cutter head; by setting serrations, the cutting sharpness of the cutter head on the cardboard is improved, and the cutting quality is improved.

[0011] Preferably, it also includes a measuring ruler, which is installed on the outer wall of the first side plate; by setting the measuring ruler, it is convenient to measure the distance between the first cutting blade, the second cutting blade, the third cutting blade and the fourth cutting blade, thereby improving the accuracy of adjustment.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By adjusting the circumferential position of the second, third, and fourth cutting blades through the drive structure, the spacing between the first, second, third, and fourth cutting blades can be flexibly adjusted. When the cardboard is conveyed below the fixed plate, the device drive shaft drives the fixed plate and the drive structure to rotate synchronously, thereby causing the first, second, third, and fourth cutting blades to move synchronously circumferentially. As a result, the cardboard is cut with notches at different positions by the first, second, third, and fourth cutting blades at different positions during the movement of the cardboard, improving the flexibility of blade adjustment, improving ease of use, and improving the cutting quality of the cardboard.

[0021] like Figures 1 to 5As shown, this utility model discloses a cardboard cross-cutting tool, including a fixed plate 5, which is mounted on the drive shaft of the equipment; it also includes a drive structure, a first cutting blade 1, a second cutting blade 2, a third cutting blade 3, and a fourth cutting blade 4. The first cutting blade 1 is fixedly mounted on the outer wall of the fixed plate 5. The drive structure is provided on both sides of the fixed plate 5. The second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4 are respectively mounted on the drive structure. The drive structure drives the second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4 to move circumferentially to different positions, and the drive structure is mounted on the drive shaft of the equipment.

[0022] like Figure 1 As shown, the drive structure includes two sets of first turntables 6, two sets of second turntables 7, two sets of third turntables 8, a first side plate 9, and a second side plate 10. The two sets of first turntables 6 are rotatably mounted on both sides of the fixed plate 5, the two sets of second turntables 7 are rotatably mounted on both sides of the two sets of first turntables 6, and the two sets of third turntables 8 are rotatably mounted on both sides of the two sets of second turntables 7. A power device is provided on the drive shaft of the equipment. The power device is used to independently drive the two sets of first turntables 6, the two sets of second turntables 7, or the two sets of third turntables 8 to rotate and adjust. The second cutting blade 2 is mounted on the two sets of first turntables 6, the third cutting blade 3 is mounted on the two sets of second turntables 7, and the fourth cutting blade 4 is mounted on the two sets of third turntables 8. The first side plate 9 is mounted on the drive shaft of the equipment and rotatably connected to the first set of third turntables 8. The second side plate 10 is mounted on the drive shaft of the equipment and rotatably connected to the second set of third turntables 8.

[0023] In this embodiment, the positions of the second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4 are adjusted circumferentially by a drive structure, allowing for flexible adjustment of the spacing between the first cutting blade 1, the second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4. When the cardboard is conveyed below the fixed plate 5, the device drive shaft drives the fixed plate 5 and the drive structure to rotate synchronously, thereby causing the first cutting blade 1, the second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4 to move circumferentially synchronously. This results in the cardboard being cut with notches at different positions by the first cutting blade 1, the second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4 during its movement, improving the flexibility of blade adjustment, enhancing ease of use, and improving the cutting quality of the cardboard.

[0024] Example 2

[0025] Based on Example 1, such as Figure 3 As shown, the cardboard cross-cutting knife of this utility model also includes a blade head 11 and an elastic pad 12. The blade head 11 is installed at a certain angle on the outer wall of the first cutting blade 1, the second cutting blade 2, the third cutting blade 3 and the fourth cutting blade 4, and the elastic pad 12 is disposed inside the blade head 11.

[0026] like Figure 2 As shown, it also includes multiple sets of threaded holes 13 and multiple sets of bolts 14. The multiple sets of threaded holes 13 are respectively set on the outer walls of the fixed plate 5, the two sets of first turntables 6, the two sets of second turntables 7 and the two sets of third turntables 8. The multiple sets of bolts 14 are respectively set on the second cutting blade 2, the third cutting blade 3 and the fourth cutting blade 4, and the multiple sets of threaded holes 13 and multiple sets of bolts 14 are installed together.

[0027] like Figure 4 As shown, it also includes a tooth 15, which is disposed at the end of the cutter head 11;

[0028] like Figure 2 As shown, it also includes a measuring ruler 16, which is mounted on the outer wall of the first side plate 9;

[0029] In this embodiment, by driving the two sets of first turntables 6 to rotate independently, the first turntables 6 drive the second cutting blade 2 to move circumferentially. By driving the two sets of second turntables 7 to rotate independently, the two sets of second turntables 7 drive the third cutting blade 3 to move circumferentially. By driving the two sets of third turntables 8 to rotate independently, the two sets of third turntables 8 drive the fourth cutting blade 4 to move circumferentially. This improves the ease of adjusting the spacing between the first cutting blade 1, the second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4, and improves the convenience of cutting notches at different positions on the cardboard. By pressing the blade head 11 into contact with the cardboard, the blade head 11 cuts notches on the cardboard. The elastic pad 12 pushes the cardboard embedded in the blade head 11 outward, preventing the cardboard from getting stuck in the blade head 11 and affecting the cutting.

[0030] This utility model discloses a cardboard cross-cutting tool. During operation, the positions of the second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4 are adjusted circumferentially through a drive structure, allowing for flexible adjustment of the spacing between the first cutting blade 1, the second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4. When the cardboard is conveyed below the fixed plate 5, the device drive shaft drives the fixed plate 5 and the drive structure to rotate synchronously, thereby causing the first cutting blade 1, the second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4 to move circumferentially synchronously. As the cardboard moves, the first cutting blade 1, the second cutting blade 2, the third cutting blade 3, and the fourth cutting blade 4 at different positions cut notches at different locations.

[0031] The above description is only a preferred embodiment of the present utility model.
