[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The listed embodiments are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0021] Example 1

[0022] Reference Figure 1 and Figure 2 This utility model provides a corner-trimming machine for cardboard packaging, including a base 1, a base 2 on the base 1, a first connecting column 3 on the upper end of the base 2, the base 2 and the first connecting column 3 being hollow, and a hydraulic pump 5 inside the base 2, a telescopic rod 6 connected to the hydraulic pump 5 with the telescopic direction extending upward along the first connecting column 3, a second connecting column 4 slidably connected inside the first connecting column 3, the second connecting column 4 being hollow and a support plate fixed inside, the end of the telescopic rod 6 away from the hydraulic pump 5 being fixedly connected to the support plate, a corner-trimming module on the second connecting column 4, a worktable 7 in the middle of the second connecting column 4, a feeding plate 8 rotatably connected to one side of the worktable 7, a limit block being provided on the feeding plate 8 near the worktable 7, and a discharge plate 9 rotatably connected to the other side of the worktable 7, with a conveyor wheel on the discharge plate 9.

[0023] The corner punching module includes a pressing machine 10, a corner punching pad 11, and a power mechanism. The pressing machine 10 is located at the top of the second connecting column 4. The front end of the pressing machine 10 is connected to the corner punching machine head 12. The corner punching pad 11 is fixed below the corner punching machine head 12 on the second connecting column 4. The power mechanism is located at the rear end of the pressing machine 10.

[0024] For example, when adjusting the height of the corner-trimming machine station, the hydraulic pump 5 drives the second connecting column 4 to move up and down via the telescopic rod 6 to adjust the height. In use, the feed plate 8 of the corner-trimming machine is connected to the external discharge port. The cardboard box to be corner-trimmed enters the feed plate 8 from the outside and stops on the feed plate 8 via a limiting block. The external discharge port can be aligned by adjusting and rotating the feed plate 8. The operator picks up the cardboard box to be corner-trimmed from the feed plate 8 and performs the corner-trimming operation using the existing corner-trimming machine, which consists of the press 10, corner-trimming pad 11, power mechanism, and corner-trimming machine head 12. After the corner-trimming is completed, the cardboard box is conveyed away by the conveyor wheels on the discharge plate 9, completing the corner-trimming operation.

[0025] The first connecting post 3 has a sliding groove 13 on its inner side, and the second connecting post 4 has a sliding strip 14 on its outer side. The sliding strip 14 and the sliding groove 13 are slidably connected.

[0026] For example, when the height of the second connecting column 4 is adjusted by the hydraulic pump 5, the slide bar 14 provided on the outer side of the second connecting column 4 will slide with the slide groove 13 provided on the inner side of the first connecting column 3 to stabilize the movement of the second connecting column 4.

[0027] The inner diameter of the first connecting post 3 is adapted to the outer diameter of the second connecting post 4, and lubricant is provided at the contact point between the slide bar 14 and the slide groove 13.

[0028] For example, by adapting the inner diameter of the first connecting post 3 to the outer diameter of the second connecting post 4, the frictional force between the first connecting post 3 and the second connecting post 4 can be controlled, and the fit between the first connecting post 3 and the second connecting post 4 can be controlled, thereby increasing the stability of the first connecting post 3 and the second connecting post 4. By providing lubricant between the slide bar 14 and the slide groove 13, the frictional force generated by the second connecting post 4 during sliding can be reduced.

[0029] Example 2

[0030] See attached document Figure 1 and attached Figure 2 Based on the aforementioned embodiments, the difference between this embodiment and the aforementioned embodiments is that: a control module is provided inside the base 2, and the hydraulic pump 5, the transmission wheel, the corner-shooting module, and the power mechanism are all electrically connected to the control module.

[0031] For example, by setting up a control module, the operation of the corner punching machine and the corner punching work of the cardboard box can be controlled, which helps to increase the automation of the device itself.

[0032] A start switch 15, an upper adjustment switch 16, and a lower adjustment switch 17 are provided on the outside of the second connecting post 4. The start switch 15, the upper adjustment switch 16, and the lower adjustment switch 17 are all electrically connected to the control module.

[0033] For example, when the angle-beating machine needs height adjustment, it can be adjusted using the upper adjustment switch 16 and the lower adjustment switch 17. When the upper adjustment switch 16 is pressed, the control module controls the hydraulic pump 5 to start. The hydraulic pump 5 drives the second connecting column 4 upward through the telescopic rod 6, and stops the movement when the upper adjustment switch 16 is pressed again. When the lower adjustment switch 17 is pressed, the hydraulic pump 5 drives the second connecting column 4 downward through the telescopic rod 6, and stops the movement when the lower adjustment switch 17 is pressed again. When the height adjustment of the angle-beating machine is complete, the start switch 15 is pressed to start the angle-beating machine to perform the corner-beating operation.

[0034] Damping pads are provided at the rotatable connection between the workbench 7 and the feed plate 8, and at the rotatable connection between the workbench 7 and the discharge plate 9.

[0035] For example, by setting damping pads, the feed plate 8 and the discharge plate 9 can provide damping when rotating with the worktable 7. The damped rotation stabilizes the feed plate 8 and the discharge plate 9 at any set angle, which is beneficial for the adjustment of the discharge plate 9 and the feed plate 8.

[0036] It should be noted that the hydraulic pump 5, the lower press 10, the power mechanism, the corner bender head 12, the control module, the transmission wheel, the start switch 15, the upper adjustment switch 16, and the lower adjustment switch 17 used in this application are all existing electronic components in the art. Those skilled in the art can understand the circuit structure and the circuit connection structure between the electronic components such as the hydraulic pump 5, the lower press 10, the power mechanism, the corner bender head 12, the control module, the transmission wheel, the start switch 15, the upper adjustment switch 16, and the lower adjustment switch 17 based on existing publicly available technical knowledge and technical information. This application embodiment will not elaborate on this in detail, and those skilled in the art can freely select the corresponding models as needed. This embodiment does not impose any specific restrictions here.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
