DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , the present utility model provides a technical solution: a packaging carton size adjustment device, including a processing table 1, a pushing plate 17, and a pressing plate 9. A limiting strip plate 2 is fixedly installed on the top of the processing table 1. The number of the limiting strip plates 2 is two groups. A positioning space is provided between the two groups of limiting strip plates 2. A driving motor 16 is arranged on the processing table 1. The pushing plate 17 is located above the processing table 1. The driving motor 16 is used to drive the pushing plate 17 to move horizontally. A support plate 3 is fixedly installed on the top of the processing table 1. An electric push rod 4 is fixedly installed on the top of the support plate 3. The electric push rod 4 is used to drive the pressing plate 9 to move up and down.

[0022] Further, two groups of mounting bottom plates 11 are fixedly installed at the bottom of the processing table 1. A threaded rod 12 is rotatably installed on the adjacent side walls of the two groups of mounting bottom plates 11. A moving block 15 is threadedly installed on the outer wall of the threaded rod 12. A guide rod 13 is fixedly installed on the adjacent side walls of the two groups of mounting bottom plates 11. The guide rod 13 is slidably installed with the moving block 15. A connecting vertical rod 14 is fixedly installed on the top of the moving block 15. The top of the connecting vertical rod 14 is fixedly installed with the bottom of the pushing plate 17. A groove for the connecting vertical rod 14 to move is opened inside the processing table 1. The bottom of the pushing plate 17 is in contact with the top of the processing table 1 and is not fixed. Such a setting can move the carton when adjusting the size of the carton, so that it is started under the cutter 6, facilitating the cutting process of the carton by the cutter 6. At the same time, such a cutting method does not require workers to manually move the carton. The automated setting can reduce the labor of workers.

[0023] Still further, the free end of the electric push rod 4 extends below the support plate 3 and is fixedly installed with a lifting plate 5. A cutter 6 is fixedly installed at the bottom of the lifting plate 5. A linkage plate 7 is fixedly installed on one side of the lifting plate 5. A telescopic spring 8 is fixedly installed at the bottom of the linkage plate 7. A pressing plate 9 is fixedly installed at the bottom of the telescopic spring 8. A stabilizing rod 10 is fixedly installed on the top of the pressing plate 9. One end of the stabilizing rod 10 extends above the linkage plate 7 and is fixedly installed with a limiting block. The linkage plate 7 is slidably installed with the stabilizing rod 10. Such a setting can press the carton through the pressing plate 9 during the downward movement of the cutter 6 for cutting, avoiding the situation of the carton shifting when being cut by the cutter 6, improving the accuracy of carton cutting, and reducing the error after carton cutting.

[0024] Secondly, a V-shaped groove for the movable cutting knife 6 is formed at the top of the processing table 1. A driving motor 16 is fixedly installed on one side of one set of mounting bases 11 on the processing table 1. The rotating shaft of the driving motor 16 is fixedly installed at one end of the threaded rod 12. A protective pad is fixedly adhered to the bottom of the cutting knife 6.

[0025] Working principle: During use, place the cardboard box on the processing table 1, and then control the driving motor 16 to start. The driving motor 16 drives the threaded rod 12 to rotate when it starts. The threaded rod 12 rotates to drive the moving block 15 to move. The moving block 15 moves to drive the connecting vertical rod 14 and the pushing plate 17 to move, so as to be able to move the cardboard box horizontally. When the cutting position of the cardboard box is directly below the cutting knife 6, control the electric push rod 4 to start. The electric push rod 4 drives the lifting plate 5 and the linkage plate 7 to descend when it starts. The descending of the lifting plate 5 drives the cutting knife 6 to descend. The descending of the cutting knife 6 can cut the cardboard box. The descending of the linkage plate 7 drives the pressing plate 9 to descend, and the descending of the pressing plate 9 can press the cardboard box.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the purpose of the present utility model.
