[0025] Example: Please refer to Figure 1-4 A CNC cardboard creasing device for carton processing includes a base plate 1, a fixed frame 2 fixedly connected to the top of the base plate 1, a lifting frame 4 inside the fixed frame 2, the center line of the lifting frame 4 and the center line of the fixed frame 2 are on the same vertical plane, and the lifting frame 4 is provided with an adjustment structure for adjusting the creasing spacing.

[0026] The adjustment structure includes a bidirectional lead screw 6, a bidirectional lead screw 6 is movably connected to the top of the inside of the lifting frame 4, threaded sleeves 5 are movably connected to both sides of the outside of the bidirectional lead screw 6, a connecting sleeve plate 19 is fixedly connected to the bottom of the threaded sleeve 5, a mounting frame 17 is fixedly connected to the bottom of the connecting sleeve plate 19, a pressure wheel 20 is movably connected inside the mounting frame 17, a limit shaft 18 is fixedly connected inside the lifting frame 4, a second servo motor 26 is fixedly connected to the left side of the top of the lifting frame 4, a second sprocket 24 is fixedly connected to the output end of the second servo motor 26, a first sprocket 23 is fixedly connected to the left side of the outside of the bidirectional lead screw 6, and a transmission chain 25 is movably connected to the outside of the second sprocket 24.

[0027] The transmission chain 25 extends into the interior of the lifting frame 4 and is movably connected to the first sprocket 23. The threaded sleeves 5 on both sides of the outer side of the bidirectional lead screw 6 are arranged symmetrically.

[0028] The connecting sleeve 19 is slidably connected to the limiting shaft 18, and the center line of the first sprocket 23 and the center line of the bidirectional lead screw 6 are on the same vertical plane.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, before pressing the wire, the second servo motor 26 at the top of the lifting frame 4 is started to drive the second sprocket 24 to rotate. The second sprocket 24 drives the bidirectional lead screw 6 to rotate through the first sprocket 23. The bidirectional lead screw 6 then drives the two sets of external threaded sleeves 5 to move. The threaded sleeves 5 drive the mounting bracket 17 and the pressing wheel 20 at the bottom to move through the connecting sleeve plate 19, adjusting the pressing wheels 20 on both sides to a suitable distance. The limiting shaft 18 fits inside the connecting sleeve plate 19 to limit the pressing wheel 20 and ensure the stability during pressing, thus realizing the ability to adjust the distance of the pressing components.

[0030] The two ends of the two sides inside the fixed frame 2 are fixedly connected to the support sleeve plate 14. The inside of the support sleeve plate 14 is movably connected to the movable plate 3. The top of the movable plate 3 is fixedly connected to the second electric cylinder 13. The output end of the second electric cylinder 13 passes through the movable plate 3 and is fixedly connected to the positioning pressure plate 21. A rubber pad 16 is fixedly connected to one side of the bottom of the positioning pressure plate 21.

[0032] Specifically, such as Figure 1 and Figure 3 As shown, before creasing, the cardboard is placed on top of the base plate 1 and kept in the middle position. Then, the third electric cylinders 15 on both sides are activated to push the movable plate 3 to move. The movable plate 3 drives the positioning pressure plate 21 at the bottom to move it to both sides of the top of the cardboard. Then, the second electric cylinder 13 at the top of the movable plate 3 is activated to push the positioning pressure plate 21 down. The positioning pressure plate 21 drives the rubber pad 16 down to fit against the top of the cardboard and position it. The support sleeves 14 at both ends fit against the outside of the movable plate 3 to limit the movable plate 3 and ensure its stability during movement, thus realizing automatic positioning of the cardboard.

[0033] The top of the fixed frame 2 is fixedly connected to the mounting cover 8, the bottom of the mounting cover 8 is movably connected to the mounting cylinder 11, the top of the lifting frame 4 is fixedly connected to the fixed cylinder 12, the top of the mounting cylinder 11 is fixedly connected to the first electric cylinder 7, the inside of the mounting cover 8 is movably connected to the threaded shaft 9, the outside of the threaded shaft 9 is movably connected to the threaded collar 10, and the front end of the mounting cover 8 is fixedly connected to the first servo motor 22.

[0035] The mounting cylinder 11 is movably connected to the fixed cylinder 12, and the output end of the first electric cylinder 7 is fixedly connected to the fixed cylinder 12.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, during the creasing process, the first electric cylinder 7 is activated to push the lifting frame 4 down. The lifting frame 4 drives the bottom creasing wheel 20 down to press it onto the top of the cardboard. Then, the first servo motor 22 is activated to drive the threaded shaft 9 to rotate. The threaded shaft 9 drives the bottom mounting cylinder 11 to move to one end through the threaded collar 10. The mounting cylinder 11 then drives the lifting frame 4 to move through the fixing cylinder 12. The lifting frame 4 drives the bottom creasing wheel 20 to move, which can automatically complete the creasing on the top of the cardboard. This realizes that the creasing wheel 20 can be automatically driven to move for creasing.

[0037] Working Principle: In use, before creasing, the cardboard is placed on top of the base plate 1 and held in the center. Then, the third electric cylinders 15 on both sides are activated to move the movable plate 3. The movable plate 3 moves the bottom positioning plate 21 to both sides of the top of the cardboard. Next, the second electric cylinder 13 on top of the movable plate 3 is activated to lower the positioning plate 21. The positioning plate 21 lowers the rubber pad 16 to fit against the top of the cardboard for positioning. The support sleeves 14 at both ends fit against the outside of the movable plate 3 to limit its movement and ensure stability. Then, the second servo motor 26 at the top of the lifting frame 4 drives the second sprocket 24 to rotate.

The two sets of threaded sleeves 5 on the outside move, and the threaded sleeves 5 drive the mounting frame 17 and the pressure roller 20 at the bottom to move through the connecting sleeve plate 19. The pressure rollers 20 on both sides are adjusted to a suitable distance, and the limiting shaft 18 fits into the inside of the connecting sleeve plate 19 to limit the pressure roller 20 and ensure the stability during pressure. When pressure is performed, the first electric cylinder 7 is started to push the lifting frame 4 down. The lifting frame 4 drives the pressure roller 20 at the bottom to fall down and press it on the top of the cardboard. Then the first servo motor 22 is started to drive the threaded shaft 9 to rotate. The threaded shaft 9 drives the mounting cylinder 11 at the bottom to move to one end through the threaded collar 10. The mounting cylinder 11 then drives the lifting frame 4 to move through the fixing cylinder 12. The lifting frame 4 drives the pressure roller 20 at the bottom to move, which can automatically complete the pressure on the top of the cardboard.
