DETAILED DESCRIPTION

[0024] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0025] Example:

[0026] like Figure 1-5 As shown, when cutting a packaging box, the cutting part will be pressed tightly, and then a cutting knife will be used for cutting. Usually, heavy objects are taken manually to press the part to be cut. Each time a cut is made, the position of the heavy object needs to be moved, and the heavy object needs to be removed from the packaging box and placed, which requires the heavy object to move a certain distance and consumes a certain amount of manpower and physical energy. For this reason, a device is designed that allows the heavy object to move only a shorter distance, so that personnel can cut packaging boxes more efficiently.

[0027] The support plates 3 are fixedly installed at the four corners of the bottom of the packaging box placement plate 1. The left and right sides of the packaging box placement plate 1 are fixedly connected with the side plates 2. The top parts of the two side plates 2 are commonly fixedly connected with the cross plate 4. The cross plate 4 is provided with a first transverse limit slide groove 5, and the first sliding plate 7 slides left and right on the first limit slide groove 5. The first threaded rod 6 is rotatably connected between the two side plates 2, and the first sliding plate 7 is threadedly connected to the outer wall of the first threaded rod 6. The servo motor 8 is fixedly installed on the side plate 2, and the power output end of the servo motor 8 is connected to the first threaded rod 6.

[0028] A second limiting slide groove 17 is provided on the left side of the first sliding plate 7, and the second sliding plate 9 is connected to the second limiting slide groove 17 in a front-rear limiting sliding manner. A cutting knife mounting plate 10 is fixedly connected to the bottom of the second sliding plate 9. A cutting knife 11 is detachably mounted on the bottom of the cutting knife mounting plate 10 for cutting the packaging box placed on the top of the packaging box placement plate 1.

[0029] The third sliding plate 12 is slidably connected to the right side of the first sliding plate 7 in an upper and lower limited position, and a sliding sleeve 18 is fixedly connected to the bottom of the third sliding plate 12. The sliding sleeve 18 is placed at the bottom of the first sliding plate 7 so that the sliding sleeve 18 is close to the cutting position of the cutting knife 11 and can press the part to be cut. The fourth sliding plate 20 is slidably connected to the inner limit position of the sliding sleeve 18, and an elastic member 19 is connected between the top of the fourth sliding plate 20 and the inner top of the sliding sleeve 18. The bottom of the fourth sliding plate 20 is fixedly connected to a pressing plate 21.

[0030] The first sliding plate 7 is provided with an up-and-down moving mechanism so that the third sliding plate 12 can move up and down, thereby making the pressing plate 21 press the packaging box.

[0031] There are two preferred embodiments of the up and down moving mechanism.

[0032] The first type: a cylinder fixing plate 22 is fixedly connected to the first sliding plate 7 , a cylinder 23 is fixedly installed on the cylinder fixing plate 22 , and a telescopic end of the cylinder 23 is connected to the third sliding plate 12 .

[0033] The second type: a threaded sleeve 16 is fixedly connected to the first sliding plate 7, the threaded sleeve 16 is internally threaded with the second threaded rod 13, and two nuts 14 are threadedly connected to the second threaded rod 13. The two nuts 14 are respectively located at the top and bottom of the threaded sleeve 16, so that the second threaded rod 13 can be stably placed at different heights. A plurality of rotating bars 15 are fixedly connected to the outer wall of the nut 14. The bottom of the second threaded rod 13 is rotatably connected to the top of the third sliding plate 12 through a bearing.

[0034] In a specific implementation, first lay the packaging box flat on the top of the packaging box placement plate 1. Then start the servo motor 8 to move the first sliding plate 7 left and right, and make the cutting knife 11 face the part that needs to be cut. At this time, start the power supply of the cylinder 23 to move the third sliding plate 12 downward, so that the pressing plate 21 can stably press the packaging box under the action of the elastic member 19. Then push the cutting knife mounting plate 10 forward to cut the packaging box. After the cutting of this part is completed, then pull back the cutting knife mounting plate 10, and move the cylinder 23 upward, so that the pressing plate 21 no longer presses the packaging box. Then start the servo motor 8 again to move the cutting knife 11 to the next cutting position, and repeat the above operation to perform the pressing and cutting operation.

[0035] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
