The first adjusting nut is disposed on the first lead screw and is connected to the right moving side connecting rod.
[0010] Furthermore, the second axial adjustment mechanism includes a second guide post, a second lead screw, and a second adjusting nut. The second guide post is mounted on the second lead screw via a second bearing, and the second adjusting nut is disposed on the second lead screw and connected to the left moving side connecting rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This invention uses a cylinder to drive a swing linkage, which in turn drives the first and second axial adjustment mechanisms to swing until the positioning wheel is blocked by a limit block. This allows for height adjustment of the front and rear pressure rods, enabling the cartoning machine to adapt to changes in the length and dimensions of cartons. Rotating the adjustment handwheel drives the first lead screw to rotate, which in turn drives the first adjusting nut to move along the lead screw. The first adjusting nut then moves the right-side moving link. Simultaneously, the first lead screw drives the second, third, and fourth lead screws to rotate synchronously via gears and chains. The second lead screw drives the second adjusting nut to move along the second lead screw, which in turn moves the left-side moving link synchronously, thus causing the rear pressure rod to move axially. This allows for adjustment of the distance between the front and rear pressure rods, enabling the cartoning machine to adapt to various carton height and dimensions, improving its applicability, ease of adjustment, and work efficiency.

[0027] The front pressure box rod 1 and the rear pressure box rod 2 are symmetrically distributed front and rear.
[0028] The first axial adjustment mechanism 3 and the second axial adjustment mechanism 4 are located above the front pressure box rod 1 and the rear pressure box rod 2, and the third axial adjustment mechanism 5 and the fourth axial adjustment mechanism 6 are located below the front pressure box rod 1 and the rear pressure box rod 2. The first axial adjustment mechanism 3 is connected to the adjustment handwheel 8, and the first axial adjustment mechanism 3, the second axial adjustment mechanism 4, the third axial adjustment mechanism 5 and the fourth axial adjustment mechanism 6 are connected by transmission.
[0029] A swing link 9 is connected between the first axial adjustment mechanism 3 and the second axial adjustment mechanism 4. The swing link 9 is connected to the cylinder 10. A positioning structure 11 is provided on the first axial adjustment mechanism 3. The positioning structure 11 and the height adjustment mechanism 7 cooperate with each other to limit the height.
[0030] The first axial adjustment mechanism 3 is connected to the front pressure box rod 1 via the right fixed side connecting rod 12 and the rear pressure box rod 2 via the right moving side connecting rod 13. The second axial adjustment mechanism 4 is connected to the front pressure box rod 1 via the left fixed side connecting rod 14 and the rear pressure box rod 2 via the left moving side connecting rod 15.
[0031] The first axial adjustment mechanism 3 includes a first guide post 16, a first lead screw 17, and a first adjusting nut 18. The first guide post 16 is mounted on the first lead screw 17 via a first bearing 19. The first lead screw 17 is connected to the adjusting handwheel 8. The first adjusting nut 18 is mounted on the first lead screw 17 and is connected to the right moving side connecting rod 13.
[0032] The second axial adjustment mechanism 4 includes a second guide post 20, a second lead screw 21, and a second adjusting nut. The second guide post 20 is mounted on the second lead screw 21 via a second bearing. The second adjusting nut is mounted on the second lead screw 21 and is connected to the left moving side connecting rod 15.
[0033] The third axial adjustment mechanism 5 includes a third guide post 22 and a third lead screw 23. The third guide post 22 is mounted on the third lead screw 23 via a third bearing 24.
[0034] The fourth axial adjustment mechanism 6 includes a fourth guide post 25 and a fourth lead screw 26. The fourth guide post 25 is mounted on the fourth lead screw 26 via a fourth bearing.
[0035] Gears 27 are respectively provided on the first lead screw 17, the second lead screw 21, the third lead screw 23 and the fourth lead screw 26, and the gears 27 are connected to each other by a chain 28.
[0036] The swing linkage 9 includes a drive rod 29, a right swing arm 30, and a left swing arm 31. The right swing arm 30 and the left swing arm 31 are hinged to both ends of the drive rod 29, and the cylinder 10 is hinged to the left swing arm 31. The left swing arm 31 is connected to the second guide post 20, and the right swing arm 30 is connected to the first guide post 16.
[0037] The height adjustment mechanism 7 includes a limit block 32 and a lifting adjustment structure 33, with the limit block 32 mounted on the lifting adjustment structure 33.
[0038] The height of the limit block 32 can be adjusted by the lifting and adjusting structure 33 to achieve the desired height setting. The lifting and adjusting structure is a screw and nut structure.

[0040] In use, the cylinder 10 retracts, driving the swing linkage 9 to swing counterclockwise. This drives the right fixed-side linkage 12, right moving-side linkage 13, left fixed-side linkage 14, and left moving-side linkage 15 to swing counterclockwise synchronously until the positioning wheel 35 is blocked by the limit block 32. At this point, the height of the front pressing rod 1 and the rear pressing rod 2 stops at the pre-set height of the limit block 32, thus enabling the adjustment of the height of the front pressing rod 1 and the rear pressing rod 2, allowing the cartoning machine to adapt to various paper box length specifications. When the cylinder 10 is raised, it drives the swing linkage 9 to swing clockwise, driving the right fixed-side linkage 12, right moving-side linkage 13, left fixed-side linkage 14, and left moving-side linkage 15 to swing clockwise synchronously. This raises the front pressing rod 1 and the rear pressing rod 2 away from the top surface of the paper box, facilitating the handling of abnormalities in the cartoning machine.
[0041] When the adjusting handwheel 8 is rotated alone, it drives the first lead screw 17 to rotate. The first lead screw 17 drives the first adjusting nut 18 to move along the first lead screw 17. The first adjusting nut 18 drives the right moving side connecting rod 13 to move. At the same time, the first lead screw 17 drives the second lead screw 21, the third lead screw 23, and the fourth lead screw 26 to rotate synchronously through the gear 27 and the chain 28. The second lead screw 21 drives the second adjusting nut to move along the second lead screw 21. The second adjusting nut drives the left moving side connecting rod 15 to move synchronously, thereby driving the rear pressing rod 2 to move axially, realizing the adjustment of the distance between the front pressing rod 1 and the rear pressing rod 2, so that the cartoning machine can adapt to the changes in the height and size of various paper boxes.
[0042] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
