They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Combine Figures 1 to 5 As shown, the utility model discloses a cardboard transverse pressing mechanism, comprising:

[0030] The transfer platform 100 comprises a support platform 110 and a conveying component 120. The support platform 110 is used to carry cardboard, and the conveying component 120 is used to convey cardboard. The support platform 110 has a transversely arranged open slot 111.

[0031] The transverse pressing unit includes a transverse pressing blade 310 and a transverse driving component 320 . The transverse driving component 320 is used to drive the transverse pressing blade 310 to perform transverse reciprocating linear motion. The bottom end of the transverse pressing blade 310 is inserted into the opening slot 111 .

[0032] The beneficial technical effects of the utility model are:

[0033] The cardboard transverse pressing mechanism of the present invention is applied to a carton forming machine. The cardboard on the support platform 110 is conveyed forward by the conveying component 120. When the cardboard reaches the pressing position, the conveying component 120 stops moving the cardboard. At this time, the transverse pressing blade 310 is staggered with the cardboard. Then, the transverse driving component 320 drives the transverse pressing blade 310 to move transversely. During the movement, the transverse pressing blade 310 presses the cardboard toward the open groove 111, so that the corresponding position of the cardboard is bent into a line toward the open groove 111, thereby realizing transverse pressing of the cardboard. The pressing line is smooth, solving the problem that the support platform 110 blocks the transverse pressing blade from pressing the cardboard, and improving the quality and aesthetics of the carton.

[0034] Furthermore, the support platform 110 has a plurality of spaced-apart hollowed-out locations; the conveying member 120 has a plurality of rollers 121, which are respectively disposed at the plurality of hollowed-out locations. The tops of the rollers 121 are higher than or equal to the surface of the support platform 110, and the paperboard is moved by the rotation of the rollers 121. The rollers 121 may be motorized rollers or driven by an external motor.

[0035] Furthermore, the outer contour of the horizontal pressing blade 310 is circular and rotatable, so that when the horizontal pressing blade 310 presses the cardboard, the blade can rotate to avoid only a local position of the horizontal pressing blade 310 being used for pressing, effectively extending the service life of the horizontal pressing blade 310.

[0036] Furthermore, in order to realize the lateral movement of the transverse pressure blade 310, the transverse driving component 320 includes a crossbeam 321, a driving motor 322, two transmission wheels 323, a synchronous belt 324, a transverse guide rail 325, a slider 326, an intermediate carrier 327 and a clamping plate 328; the two transmission wheels 323 are rotatably mounted on the crossbeam 321 through a bracket 341, the two transmission wheels 323 are connected by the synchronous belt 324, the driving motor 322 is fixedly mounted on one of the brackets 341 and is drivingly connected to the transmission wheel 323 on the bracket 341, the transverse guide rail 325 is installed on the crossbeam 321, the transverse guide rail 325 is parallel to the synchronous belt 324, the intermediate carrier 327 is installed on the slider 326, one side of the synchronous belt 324 is against the intermediate carrier 327, and the clamping plate 328 is used to fix the synchronous belt 324 and the intermediate carrier 327; the intermediate carrier 327 is connected to the transverse pressure blade 310; the drive motor 322 drives the transmission wheel 323 to rotate, and the rotation of the transmission wheel 323 drives the movement of the synchronous belt 324, thereby driving the transverse pressure blade 310 on the intermediate carrier 327 to move horizontally.

[0037] Furthermore, in order to enable the transverse pressure blade 310 to rotate while moving laterally, the transverse driving component 320 also includes a transverse rack 329, which is installed on the crossbeam 321 and arranged parallel to the transverse guide rail 325; the intermediate carrier 327 includes a first carrier plate 3271 and a second carrier plate 3272, the first carrier plate 3271 is fixedly connected to the slider 326, and the second carrier plate 3272 is uprightly arranged on the outer side of the first carrier plate 3271, and a gear transmission component is provided on the second carrier plate 3272, which is in transmission connection with the transverse rack 329, and the transverse pressure blade 310 is fixedly connected to the gear transmission component. As the synchronous belt 324 moves, it drives the intermediate carrier 327 to move, causing the gear transmission component on the second carrier plate 3272 to move laterally. When the gear transmission component moves laterally, it engages with the transverse rack 329 for transmission, and the gear transmission component rotates, thereby driving the transverse pressing blade 310 to rotate. That is, the transverse pressing blade 310 rotates while relying on the transverse driving component 320 to drive the transverse pressing blade 310 to move laterally, rather than simply relying on the contact friction with the cardboard to rotate. This can reduce the friction between the transverse pressing blade 310 and the cardboard, effectively extend the service life of the transverse pressing blade 310, avoid damage to the cardboard due to friction with the transverse pressing blade 310, and effectively improve the quality of the cardboard.

[0038] Furthermore, the gear transmission component includes a first gear 330 and a second gear 331, the first gear 330 is meshed with the transverse rack 329 for transmission, the first gear 330 and the second gear 331 are transmitted in a flat meshing manner, the transverse pressure blade 310 is fixedly connected to the second gear 331, the diameter of the first gear 330 is larger than the diameter of the second gear 331, that is, the first gear 330 is a large gear, and the second gear 331 is a small gear. The large gear drives the small gear to rotate, thereby increasing the rotation speed of the small gear, and then increasing the rotation speed of the transverse pressure blade 310 fixedly connected to the small gear, thereby effectively reducing the friction between the transverse pressure blade 310 and the cardboard, and extending the service life of the transverse pressure blade 310.

[0039] Furthermore, the cardboard transverse pressing mechanism also includes a paper discharge unit, which includes multiple roller groups 340 distributed along the transverse direction. The roller group 340 includes a bracket 341, a connecting shaft 342, and multiple rollers 343. The bracket 341 is mounted on the crossbeam 321. The connecting shaft 342 passes through both sides of the bracket 341 and can move up and down relative to the bracket 341. The rollers 343 are rotatably mounted on the connecting shaft 342 via bearings. The multiple rollers 343 press on the cardboard, reducing the extent to which the cardboard is tilted upward due to pressing, ensuring that the bottom plate of the cardboard maintains contact with the conveying component 120 on the transfer platform 100, ensuring the conveyance of the cardboard.

[0040] Furthermore, the bracket 341 has strip-shaped slots 3411 on both sides, which are arranged obliquely or vertically. The two ends of the connecting shaft 342 are respectively inserted into the two strip-shaped slots 3411. When the connecting shaft 342 abuts the bottom sides of the strip-shaped slots 3411, the distance between the roller 343 and the transfer platform 100 is less than the thickness of the cardboard. Because the arrangement of the strip-shaped slots 3411 provides conditions for the roller 343 to move upward, when the cardboard passes by the roller 343, the cardboard pushes the roller 343 up, and the roller 343 maintains pressure on the cardboard under the action of gravity, so that the bottom surface of the cardboard maintains contact with the conveying member 120 on the transfer platform 100. Furthermore, the paper discharge unit can be used with a variety of cardboard thicknesses, the difference being that the height to which the roller 343 is lifted varies depending on the thickness of the cardboard, thereby improving the versatility of the cardboard transverse pressing mechanism.

[0041] It should be noted that the arrow direction not explained in the drawings is the cardboard conveying direction.

[0042] The utility model also discloses a carton forming machine, which comprises the cardboard transverse pressing mechanism described above.
