[0023] The following elaborates on the preferred embodiments of the present utility model in conjunction with the attached drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0024] Refer to Figures 1-3 , a device for cutting the corners of a packaging carton, including a workbench 1 and a cutting mechanism and a positioning and adjusting mechanism installed on the workbench 1. The cutting mechanism includes a first motor 2, a driving shaft 3, and a cutting blade 9. The driving shaft 3 is installed at the output end of the first motor 2, and two cutting blades 9 are slidably arranged opposite to each other on the driving shaft 3;

[0025] The positioning and adjusting mechanism includes a moving seat 4, a moving ring 5, an adjusting plate 7, a second motor 12, and a bi-directional lead screw 13. The second motor 12 is arranged below the first motor 2, and the bi-directional lead screw 13 is installed at the output end of the second motor 12. There are two groups of adjusting plates 7, which are oppositely and drivingly connected to the bi-directional lead screw 13 and slide along the slide groove 101. The moving seat 4 is slidably connected to the driving shaft 3 and is rotationally connected through a rotating ring 8. The moving ring 5 is sleeved and slid on the moving seat 4 and is fixedly connected to the adjusting plate ⑦ and can be locked to the moving seat 4 through a bolt 6;

[0026] A first guiding plate 11 is further fixed to the lower end of the moving seat 4;

[0027] According to the width of the carton, drive the second motor 12 to drive the adjusting plate 7 to move through the bi-directional lead screw 13. The adjusting plate 7 synchronously drives the moving seat 4 to push the cutting blade 9 to move. After the distance between the two groups of adjusting plates 7 is adjusted, the bolt 6 can be loosened, and the moving seat 4 is moved to make the cutting blade 9 correspond to the position of the packaging carton to be cut, so that the device can perform a fixed-length cutting on the side of the packaging carton. Then, the moving seat 4 and the moving ring 5 can be limited through the bolt 6;

[0028] At this time, the first motor 2 can be driven to synchronously drive the cutting blade 9 to rotate through the driving shaft 3, and the packaging carton is pushed to cut the side of the packaging carton. When the cut waste touches the first guiding plate 11, the cut waste can be guided to fall below the workbench 1 to avoid the accumulation of the cut waste on the workbench 1 and affect the subsequent cutting of the side of the packaging carton.

[0029] At the blanking opening of the workbench 1, an extension plate 10 and a second guiding plate 14 are respectively installed on both sides of the bidirectional lead screw 13; the extension plate 10 is arranged in a flat plate structure, and the second guiding plate 14 is arranged in an arc plate structure. The highest point of the second guiding plate 14 is flush with the middle surface of the workbench 1; when pushing the carton, the carton is pushed between the two adjusting plates 7, and the two adjusting plates 7 are used to limit the carton to ensure that the carton is pushed straight. The cooperation of the extension plate 10 and the second guiding plate 14 can ensure that the carton normally passes through the blanking opening of the workbench 1, so that the side of the carton can be normally cut off by the cutting blade 9.

[0030] A baffle plate 1101 is also installed at the bottom surface of the upper end of the first guiding plate 11; the distance between the first guiding plate 11 and the cutting blade 9 is set to be less than 0.5 cm. So when the side of the carton is cut off by the cutting blade 9, the waste material cut off from the carton will contact the first guiding plate 11, and through the guidance of the first guiding plate 11, the waste material will fall below the workbench 1.

[0031] A plurality of sliding grooves are formed on the outer wall of the driving shaft 3. The rotating ring 8 is slidably embedded on the driving shaft 3 through the convex key in the middle thereof. The inner wall of the moving seat 4 is arranged in a circular hole structure and fits and slides on the outer wall of the driving shaft 3; the driving shaft 3 can normally drive the cutting blade 9 to rotate synchronously, while the moving ring is not affected by the rotation of the driving shaft 3 and will not be driven to rotate by the driving shaft 3.

[0032] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
