Technical Field

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

[0002] As a basic material for the packaging, logistics and printing industries, efficient and precise processing of cardboard is a key link in ensuring the production efficiency and product quality of downstream industries.

[0003] Currently, in the cutting and processing of cardboard, as exemplified by the patent with prior art authorization announcement number CN211466641U, this utility model relates to a corrugated cardboard cross-cutting machine, including a frame, an upper cutter roller, a lower cutter roller, a conveyor roller and a pressure roller for transmitting the corrugated cardboard, and a first motor for driving the conveyor roller to rotate. The upper cutter roller is slidably connected to the frame, and the lower cutter roller is rotatably connected to the frame. A second motor for driving the lower cutter roller to rotate is provided on the frame. The upper and lower cutter rollers are provided with a cutter assembly along their length direction. The cutter assembly includes a mounting seat, a blade rotatably connected to the mounting seat, and an adjusting plate for adjusting the blade angle. The mounting seat is connected to the upper or lower cutter roller, and the adjusting plate is embedded and slidably connected to the blade.

[0004] However, it was found during the use of the equipment that the adjustment flexibility and convenience of the blades were poor, which increased the limitations of its use in cutting different types of cardboard. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cardboard cross-cutting machine that improves the convenience of adjusting the circumferential and left-right spacing between multiple sets of cutters, improves the convenience of cutting notches with different spacings on cardboard, and improves the convenience of cutting cardboard of different widths.

[0006] This utility model discloses a cardboard cross-cutting machine, comprising a machine body and a first rotating shaft, with both ends of the first rotating shaft rotatably mounted on the machine body; it also includes a drive device, an adjustment device, a first cutter disc, cutters, a second rotating shaft, and a second cutter disc, with both ends of the second rotating shaft rotatably mounted on the machine body. Multiple sets of first cutter discs are rotatably connected to each other, and multiple sets of second cutter discs are rotatably connected to each other. The multiple sets of first and second cutter discs are rotatably and slidably mounted on the left and right sides of the outer wall of the first rotating shaft, respectively. A drive device is provided on the first rotating shaft to drive the multiple sets of first and second cutter discs to rotate. Multiple sets of cutters are respectively mounted on the outer walls of the multiple sets of first and second cutter discs at different positions. The adjustment device is located on the machine body and is used to drive the first and second cutter discs to move in opposite directions. The cardboard to be cut is fed between the first and second rotating shafts. Rotating the first rotating shaft causes the first and second cutting discs to rotate, which in turn causes multiple sets of cutting tools to move circumferentially. These cutting tools, in conjunction with the second rotating shaft, cut notches into the cardboard. A drive device individually rotates and adjusts multiple sets of the first and second cutting discs, allowing the cutting tools at corresponding positions on both sides to move circumferentially. This improves the ease of adjusting the spacing between the multiple sets of cutting tools and the ability to cut notches of varying spacing on the cardboard. An adjustment device moves the first and second cutting discs in opposite directions, allowing for adjustment of the spacing between the cutting tools on the left and right sides, further improving the ease of cutting cardboard of different widths.

[0007] Preferably, the drive device includes gears, gear rings, side plates, shaft seats, mounting plates, multiple sets of hexagonal rods, and multiple sets of motors. The multiple sets of shaft seats are all mounted on the right side of the first rotating shaft, and the mounting plate is mounted on the left side of the first rotating shaft. The two ends of the multiple sets of hexagonal rods are rotatably mounted on the multiple sets of shaft seats and the mounting plate, respectively. The multiple sets of hexagonal rods all pass through the interiors of the multiple sets of first and second cutter discs. Multiple sets of gears are slidably mounted left and right on the multiple sets of hexagonal rods. Multiple sets of gear rings are respectively mounted on the inner sidewalls of the multiple sets of first and second cutter discs. Multiple sets of side plates are respectively mounted on both sides of the multiple sets of gear rings. The multiple sets of gears mesh with the multiple sets of gear rings. Multiple sets of motors are all mounted on... Mounted on the outer wall of the mounting plate, multiple sets of motor outputs are connected to multiple sets of hexagonal rods. After the first rotating shaft rotates, it drives multiple sets of shaft seats to move circumferentially, causing multiple sets of shaft seats to drive multiple sets of first cutter discs and multiple sets of second cutter discs to rotate as a whole through multiple sets of gears and multiple sets of gear rings. This causes multiple sets of cutters to move circumferentially to cut the cardboard. Multiple sets of motors drive multiple sets of hexagonal rods to rotate, and the rotation of multiple sets of hexagonal rods drives multiple sets of gears to rotate. The multiple sets of gears, through meshing with multiple sets of gear rings, drive multiple sets of first cutter discs and multiple sets of second cutter discs to rotate individually, thereby allowing the position of multiple sets of cutters to be moved and adjusted, improving the flexibility of adjusting the spacing between multiple sets of cutters.

[0008] Preferably, the adjustment device includes two sets of connecting parts, guide columns, a bidirectional lead screw, and two sets of pushing parts. The two sets of pushing parts are rotatably connected to the first cutter head and the second cutter head, respectively. The two sets of connecting parts are connected to the two sets of pushing parts, respectively. The guide columns are installed on the outer wall of the machine body, and the two sets of connecting parts are slidably installed on the guide columns. The bidirectional lead screw is rotatably installed on the machine body, and the two sets of connecting parts are fitted onto the bidirectional lead screw. By rotating the bidirectional lead screw, the bidirectional lead screw drives the two sets of connecting parts to move in opposite directions, and the two sets of connecting parts drive the first cutter head and the second cutter head to move in opposite directions through the two sets of pushing parts. This improves the convenience of adjusting the spacing between the multiple sets of cutters on both sides and improves the convenience of cutting paperboard of different widths. When the multiple sets of first cutter heads and multiple sets of second cutter heads move in opposite directions, the multiple sets of side plates drive the multiple sets of gears to slide left and right, thereby improving the convenience of the multiple sets of hexagonal rods driving the multiple sets of first cutter heads and multiple sets of second cutter heads to rotate.

[0009] Preferably, it also includes two sets of third rotating shafts and two sets of conveyor wheels. The two sets of third rotating shafts are rotatably mounted on the machine body, and the two sets of conveyor wheels are respectively mounted on the outer walls of the two sets of third rotating shafts. The cardboard is passed between the two sets of third rotating shafts and the two sets of conveyor wheels, and the two sets of third rotating shafts drive the two sets of conveyor wheels to rotate in opposite directions, thereby improving the convenience of cardboard conveying.

[0010] Preferably, it also includes two sets of protective covers, which are respectively installed on the rightmost first cutter head and the leftmost second cutter head, and the two sets of protective covers are fitted onto multiple sets of hexagonal rods; by setting two sets of protective covers, the shielding and protection effect inside the multiple sets of first cutter heads and multiple sets of second cutter heads is improved.

[0011] Preferably, the machine body is provided with a power mechanism, which is used to drive the first rotating shaft, the second rotating shaft, the bidirectional lead screw and two sets of third rotating shafts to rotate, thereby improving the ease of use.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The cardboard to be cut is conveyed between the first rotating shaft and the second rotating shaft. By rotating the first rotating shaft, the first rotating shaft drives the first and second cutting discs to rotate, thereby causing the first and second cutting discs to drive multiple sets of cutters to move circumferentially. The multiple sets of cutters cooperate with the second rotating shaft to cut notches into the cardboard. By using a driving device to drive multiple sets of first and second cutting discs to rotate and adjust individually, the cutters at corresponding positions on both sides move circumferentially, thereby improving the convenience of adjusting the spacing between the multiple sets of cutters arranged circumferentially and improving the convenience of cutting notches with different spacings on the cardboard. By using an adjustment device to drive the first and second cutting discs to move in opposite directions, the spacing between the cutters on the left and right sides can be adjusted, improving the convenience of adjusting the cutting of cardboard of different widths.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0020] like Figures 1 to 5 As shown, this utility model discloses a cardboard cross-cutting machine, including a machine body 1 and a first rotating shaft 2, with both ends of the first rotating shaft 2 rotatably mounted on the machine body 1; it also includes a drive device, an adjustment device, a first cutter disc 3, cutters 4, a second rotating shaft 5, and a second cutter disc 16, with both ends of the second rotating shaft 5 rotatably mounted on the machine body 1; multiple sets of first cutter discs 3 are rotatably connected to each other, and multiple sets of second cutter discs 16 are rotatably connected to each other; the multiple sets of first cutter discs 3 and multiple sets of second cutter discs 16 are rotatably and slidably mounted on the left and right sides of the outer side wall of the first rotating shaft 2, respectively; a drive device is provided on the first rotating shaft 2, which is used to drive the multiple sets of first cutter discs 3 and multiple sets of second cutter discs 16 to rotate respectively; multiple sets of cutters 4 are respectively mounted on the outer side walls of the multiple sets of first cutter discs 3 and second cutter discs 16 at different positions; and an adjustment device is provided on the machine body 1, which is used to drive the first cutter discs 3 and second cutter discs 16 to move in opposite directions.

[0021] like Figure 3As shown, the drive device includes gears 6, gear rings 7, side plates 8, bearing seats 9, mounting plates 10, multiple sets of hexagonal rods 17, and multiple sets of motors 18. The multiple sets of bearing seats 9 are all installed on the right side of the first rotating shaft 2, and the mounting plates 10 are installed on the left side of the first rotating shaft 2. The two ends of the multiple sets of hexagonal rods 17 are respectively rotatably installed on the multiple sets of bearing seats 9 and mounting plates 10. The multiple sets of hexagonal rods 17 all pass through the interior of the multiple sets of first cutter discs 3 and multiple sets of second cutter discs 16. The multiple sets of gears 6 are respectively slidably installed on the multiple sets of hexagonal rods 17. The multiple sets of gear rings 7 are respectively installed on the inner side walls of the multiple sets of first cutter discs 3 and multiple sets of second cutter discs 16. The multiple sets of side plates 8 are respectively installed on both sides of the multiple sets of gear rings 7. The multiple sets of gears 6 mesh with the multiple sets of gear rings 7. The multiple sets of motors 18 are all installed on the outer side wall of the mounting plates 10, and the output ends of the multiple sets of motors 18 are respectively connected to the multiple sets of hexagonal rods 17.

[0022] In this embodiment, the cardboard to be cut is conveyed between the first rotating shaft 2 and the second rotating shaft 5. By rotating the first rotating shaft 2, the first rotating shaft 2 drives the first cutting disc 3 and the second cutting disc 16 to rotate, thereby causing the first cutting disc 3 and the second cutting disc 16 to drive multiple sets of cutters 4 to move circumferentially. The multiple sets of cutters 4 cooperate with the second rotating shaft 5 to cut notches into the cardboard. The driving device drives multiple sets of first cutting discs 3 and multiple sets of second cutting discs 16 to rotate and adjust individually, thereby causing the cutters 4 at corresponding positions on both sides to move circumferentially. This improves the convenience of adjusting the spacing between the multiple sets of cutters 4 arranged circumferentially, and improves the convenience of cutting notches with different spacing on the cardboard. The adjusting device drives the first cutting disc 3 and the second cutting disc 16 to move in opposite directions, so that the spacing between the cutters 4 on the left and right sides can be adjusted, improving the convenience of adjusting the cutting of cardboard of different widths. Example 2

[0023] Based on Example 1, such as Figure 1 As shown, this utility model discloses a cardboard cross-cutting machine. The adjustment device includes two sets of connecting parts 11, guide columns 12, bidirectional screws 13, and two sets of pushing parts 19. The two sets of pushing parts 19 are rotatably connected to the first cutter disc 3 and the second cutter disc 16, respectively. The two sets of connecting parts 11 are connected to the two sets of pushing parts 19, respectively. The guide columns 12 are installed on the outer wall of the machine body 1. The two sets of connecting parts 11 are slidably installed on the guide columns 12. The bidirectional screws 13 are rotatably installed on the machine body 1. The two sets of connecting parts 11 are fitted onto the bidirectional screws 13.

[0024] like Figure 1 As shown, it also includes two sets of third rotating shafts 14 and two sets of conveying wheels 15. Both sets of third rotating shafts 14 are rotatably mounted on the machine body 1, and the two sets of conveying wheels 15 are respectively mounted on the outer side walls of the two sets of third rotating shafts 14.

[0025] like Figure 2As shown, it also includes two sets of protective covers 20, which are respectively installed on the rightmost first cutter head 3 and the leftmost second cutter head 16, and the two sets of protective covers 20 are fitted onto multiple sets of hexagonal rods 17.

[0026] like Figure 1 As shown, the machine body 1 is equipped with a power mechanism, which is used to drive the first rotating shaft 2, the second rotating shaft 5, the bidirectional lead screw 13 and the two sets of third rotating shafts 14 to rotate.

[0027] In this embodiment, after the first rotating shaft 2 rotates, it drives multiple sets of bearing seats 9 to move circumferentially. These bearing seats 9, through multiple sets of gears 6 and multiple sets of gear rings 7, drive multiple sets of first cutter discs 3 and multiple sets of second cutter discs 16 to rotate as a whole. This causes multiple sets of cutters 4 to move circumferentially to cut the cardboard. Multiple sets of motors 18 drive multiple sets of hexagonal rods 17 to rotate. The rotation of the hexagonal rods 17 then drives the multiple sets of gears 6 to rotate. The gears 6, through meshing with the gear rings 7, drive multiple sets of first cutter discs 3 and multiple sets of second cutter discs 16 to rotate individually, thereby adjusting the position of the multiple sets of cutters 4 and improving their position. The flexibility of spacing adjustment is enhanced by rotating the bidirectional lead screw 13, which drives two sets of connecting parts 11 to move in opposite directions. These connecting parts 11, in turn, drive the first cutter head 3 and the second cutter head 16 to move in opposite directions via two sets of pushers 19. This improves the ease of adjusting the spacing between the multiple sets of cutters 4 on both sides and enhances the ease of cutting cardboard of different widths. When the multiple sets of first cutter heads 3 and multiple sets of second cutter heads 16 move in opposite directions, the multiple sets of side plates 8 drive the multiple sets of gears 6 to slide left and right, thereby improving the ease of driving the multiple sets of first cutter heads 3 and multiple sets of second cutter heads 16 to rotate via the multiple sets of hexagonal rods 17.

[0028] This utility model discloses a cardboard cross-cutting machine. During operation, the cardboard to be cut is conveyed between a first rotating shaft 2 and a second rotating shaft 5. Rotating the first rotating shaft 2 causes the first cutter disc 3 and the second cutter disc 16 to rotate, thereby causing the first cutter disc 3 and the second cutter disc 16 to move multiple sets of cutters 4 circumferentially. These cutters 4, in conjunction with the second rotating shaft 5, cut notches into the cardboard. A driving device individually rotates and adjusts multiple sets of first cutter discs 3 and multiple sets of second cutter discs 16, thereby causing the cutters 4 at corresponding positions on both sides to move circumferentially, adjusting the spacing between the multiple sets of circumferentially arranged cutters 4. An adjusting device then moves the first cutter disc 3 and the second cutter disc 16 in opposite directions, adjusting the spacing between the cutters 4 on the left and right sides.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
