[0002] With the continuous development of the economy, the demand for cardboard packaging is increasing, involving more and more industries. Compared with the traditional carton making process, the carton forming machine can be used for small-batch, multi-specification carton production. Its carton production efficiency is high, and only one operator is needed to complete the carton production operation. The carton forming machine generally includes modules such as cardboard feeding, slotting, longitudinal creasing, transverse creasing, and punching. When the cardboard is being processed, it is necessary to punch holes in the specified positions of the cardboard. It is often used to first use a punching structure to punch the specified position of the cardboard to form a hole-shaped contour indentation on the cardboard, but the contour indentation will not cause the hole to separate from the cardboard, and the staff will subsequently remove the cardboard within the contour indentation range. After the punching structure in the prior art punches the cardboard, the cardboard will adhere to the punching die. When the punching die rises, it will drive the cardboard up, affecting the transportation of the cardboard to other modules and affecting the production work of the carton forming machine.

[0028] The punching unit includes a punching table 410 and a punching component 420; the punching component 420 includes a support frame 421, a punching cylinder 422, and a punching die 423. The punching die 423 is located above the punching table 410. The punching cylinder 422 is fixed to the support frame 421 and is used to drive the punching die 423 to move up and down.

[0029] A conveying unit, comprising a driving component and two rollers 440 , the two rollers 440 being located on either side of the punching table 410 , with the tops of the rollers 440 being flush with the upper surface of the punching table 410 ;

[0030] Two paper pressing units are respectively located above the two rollers 440. The paper pressing units include a paper pressing wheel 450 and a cantilever arm 460. The cantilever arm 460 is connected to the support frame 421 through a spring 490 so that the cantilever arm 460 can move in a vertical direction relative to the support frame 421. The paper pressing wheel 450 is rotatably set on the cantilever arm 460, and the paper pressing wheel 450 is against the roller 440.

[0031] Furthermore, a rubber plate is provided on the upper surface of the punching table 410. When the punching die 423 punches the cardboard, the punching die 423 presses the rubber plate, effectively avoiding direct contact between the punching die 423 and the punching table 410, and effectively extending the service life of the punching die 423 and the punching table 410.

[0032] Furthermore, the axial length of the roller 440 is greater than the axial length of the paper pressing wheel 450 to avoid slipping.

[0033] Furthermore, the driving component includes a driving shaft 431 and a driving motor 432. The driving shaft 431 passes through the bottom of the punching table 410 and is connected to the two rollers 440. The driving motor 432 is connected to the driving shaft 431 to drive the two rollers 440 to rotate synchronously to ensure stable transportation of the cardboard and avoid deviation of the cardboard due to uneven force on the two rollers 440 due to inconsistent rotation speeds.

[0034] Furthermore, cardboards of different specifications may have different punching positions. In order to make the cardboard punching mechanism applicable to cardboards of various specifications, the cardboard punching mechanism includes a first transverse moving component 470 and a second transverse moving component; the first transverse moving component 470 is connected to the support frame 421 so that the support frame 421 can move laterally, and then the punching cylinder 422 and the punching die located on the support frame 421 can move laterally synchronously with the support frame 421, so that the transverse position of the punching die 423 can be adjusted according to cardboards of different specifications; the second transverse moving component is connected to the punching table 410 and the two rollers 440 so that the punching table 410 and the two rollers 440 can move laterally, so that the transverse position of the punching table 410 and the two rollers 440 can be adjusted according to cardboards of different specifications.

[0035] Furthermore, the first transverse moving component 470 includes a crossbeam 471 and a first slide rail 472 . The first slide rail 472 is transversely arranged on the crossbeam 471 . The support frame 421 is connected to the first slide rail 472 via a first slider so that the support frame 421 can move transversely.

[0036] Furthermore, a laterally extending scale is provided on the crossbeam 471; a pointer 473 is fixed to the support frame 421, and the pointer 473 is close to and points to the scale. Workers can mark the scale according to the different cardboard specifications, and the mark must be aligned with the pointer 473. This allows workers to quickly move the punching die 423 to the corresponding position during production changes. Once the punching die 423 is in place, the punching table 410 and roller 440 are moved to the corresponding positions based on the position of the punching die 423, making production changes quick and convenient.

[0037] Furthermore, the second transverse moving component further includes a support platform 500 and a second slide rail 481, which is transversely arranged on the support platform. The punching platform 410 is connected to the second slide rail 481 via a second slider 482. Supports 484 are connected to opposite sides of the two rollers 440, and the supports 484 are connected to the second slide rail 481 via a third slider 483. The cross-section of the drive shaft 431 is a polygonal structure. In this way, the drive shaft 431 can transmit power to rotate the rollers 440 while also allowing the rollers 440 to move transversely along the drive shaft 431. The drive shaft 431 is preferably a hexagonal shaft.

[0038] It should be noted that corresponding positioning holes can be set on the beam 471 and the support platform according to different specifications of cardboard, and pins can be set on the support frame 421, the support 484 and the punching platform 410 to realize the positioning and fixation of the punching die 423, the roller 440 and the punching platform 410 by plugging the pins into the positioning holes.

[0039] The utility model also discloses a carton forming machine, comprising the cardboard punching mechanism described above.

[0040] So far, the present embodiment has been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the cardboard punching mechanism of the present invention. The cardboard punching mechanism of the present invention is applied to a carton forming machine. During the punching process, the cardboard is pressed by the cooperation of the pressure wheel 450 and the roller 440, which effectively solves the problem that the cardboard adheres to the punching die 423 and rises with the punching die 423; specifically, the two rollers 440 are driven by the driving component to rotate until the cardboard passes between the pressure wheel 450 and the roller 440 and after the cardboard reaches the preset position, the two rollers 440 stop rotating, and when the paper wheel passes through the pressure wheel 450 When the cardboard is between the roller 440 and the pressing wheel 450, the spring 490 is subjected to a compression force, so the pressing wheel 450 will continue to press the cardboard. After the roller 440 stops rotating, the pressing of the cardboard by the pressing wheel 450 can fix the position of the cardboard. Then the punching cylinder 422 drives the punching die 423 to descend and punch the cardboard on the punching table 410 to complete the punching operation of the cardboard. After the punching is completed, the driving component drives the two rollers 440 to rotate, transporting the cardboard forward, so that the cardboard leaves the punching table 410.
