Description

Technical Field

[0001] The utility model relates to the technical field of edge material cutting, in particular to an edge material cutting device for a carton printing machine. Background Art

[0002] A carton printing machine is a machine device specifically used for printing cartons, which can print contents such as words, patterns, logos, etc. on the surface of cartons to meet the production and packaging requirements. The main working principle of the carton printing machine is to print printing ink on the surface of the carton through the printing cylinder or printing plate on the printing machine. During the carton printing process, some edge materials or waste materials are often generated, and a cutting device is needed to cut off the redundant corners for subsequent processing.

[0003] The cutting of the corners of the redundant printing machine generally uses a tool for cutting. For smaller or thinner edge materials, a tool is used for cutting. Common tools include blades, cutting knives, etc. However, since it is cutting after printing, after printing, the pressing effect on the carton will also end with the end of printing. At this time, cutting may cause the situation of cutting misalignment. Although the tool cuts the cardboard quickly and is relatively sharp, it cannot guarantee whether the unfixed cardboard will produce a certain offset, resulting in cutting to the printed pattern.

[0004] However, in the prior art, when cutting the edge materials of cartons, the cartons are stacked on the cutting table, and the stacked cartons are uneven, and workers are required to adjust and correct the cartons. This process takes a lot of time, not only reducing the overall production efficiency, but also increasing the labor intensity of workers. If directly cut, if directly cut off, it will cause the cartons to be cut unevenly, and even mis-cut the effective printing area of the cartons, thus affecting the product quality. Therefore, an edge material cutting device for a carton printing machine is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art, such as reducing the overall production efficiency, increasing the labor intensity of workers, and at the same time, mis-cutting the effective printing area of the cartons, thus affecting the product quality, and to propose an edge material cutting device for a carton printing machine.

[0007] The correction mechanism includes a base, two sets of moving plates and a connecting frame plate. Telescopic rods are fixedly installed at the upper end of the base near the positions of both side edges. Push plates are fixedly installed at the upper ends of the two sets of moving plates. A movable plate is rotatably installed at the protruding part of the upper end of the base. Connecting pieces are rotatably installed at the protruding parts of the upper ends of the two sets of moving plates. Four cylinders are fixedly installed at the inner bottom end of the connecting frame plate.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As shown in FIG. Figure 1 -4, the present utility model provides an edge material cutting device for a carton printing machine, including a processing table 1 and an edge material cutting mechanism 14. Six vertical holes 11 are penetrated through the upper end of the processing table 1, and limiting plates 12 are fixedly installed at both sides of the upper end of the processing table 1 near the edge positions, and a correction mechanism 2 is arranged at the lower end of the processing table 1;

[0025] The correction mechanism 2 includes a base 21, two groups of moving plates 23 and a connecting frame plate 27. Telescopic rods 22 are fixedly installed at the upper end of the base 21 near the positions of both side edges. Push plates 24 are fixedly installed at the upper ends of the two groups of moving plates 23. A movable plate 25 is rotatably installed at the protruding part of the upper end of the base 21. Connecting pieces 26 are rotatably installed at the protruding parts of the upper ends of the two groups of moving plates 23. Four cylinders 28 are fixedly installed at the inner bottom end of the connecting frame plate 27. Four guide rails 29 are fixedly installed at the upper end of the base 21. Sliding seats 210 are slidably installed on the outer walls of the four guide rails 29. The upper ends of the four sliding seats 210 are respectively fixed to the lower ends of the two groups of moving plates 23. The telescopic ends of the two telescopic rods 22 are respectively fixed to one end of one of the two groups of moving plates 23. The six push plates 24 are respectively inserted into the six vertical holes 11. The other ends of the two connecting pieces 26 are respectively rotatably installed on the outer walls of the two protruding parts at the upper end of the movable plate 25. The extending ends of the four cylinders 28 are respectively fixed to the lower end of the base 21. The protruding ends of the connecting frame plate 27 are respectively fixed to the bottom end of the support cross beam of the processing table 1.

[0026] Next, specifically describe the specific settings and functions of this embodiment. Start the operation of the four cylinders 28. The four cylinders 28 drive other structures in the correction mechanism 2 to drive the six push plates 24 to move upward, so that the six push plates 24 move upward respectively inside the six vertical holes 11. After being flush with the limiting plates 12, start the two telescopic rods 22. The extending ends of the two telescopic rods 22 move one of the two groups of moving plates 23. One of the moving plates 23 will drive three of the six push plates 24 to move, and at the same time will also drive one of the connecting pieces 26 to move, so that one of the connecting pieces 26 drives the movable plate 25 to rotate at the protruding part of the base 21, and the movable plate 25 drives the other connecting piece 26 to move, and the other connecting piece 26 drives the other group of moving plates 23 to move, so that the two groups of moving plates 23 move towards the middle of the base 21. Among them, one ends of the two connecting pieces 26 rotate on the outer walls of the protruding parts of the two groups of moving plates 23 respectively, and the other ends of the two connecting pieces 26 rotate on the outer walls of the two protruding parts of the movable plate 25 respectively, which is convenient for one of the connecting pieces 26 to drive the other connecting piece 26 to move through the movable plate 25, and then enables the two groups of moving plates 23 to drive the six push plates 24 to move, and the six push plates 24 slide respectively inside the six vertical holes 11. Cooperating with the two limiting plates 12, the two sides of the cardboard box can be limited, so that the cardboard box can be adjusted and corrected, saving a lot of time, not only improving the overall production efficiency, but also reducing the labor intensity of workers, and preventing the occurrence of uneven straight cutting or mis-cutting of the effective printing area, improving the product quality.

[0027] When the two groups of moving plates 23 move, the two groups of moving plates 23 drive the four sliding seats 210 to move, so that the four sliding seats 210 slide respectively on the four guide rails 29, making the movement of the two groups of moving plates 23 smoother, and at the same time can also improve the stability of the two groups of moving plates 23 when moving.

[0028] Embodiment 2: As Figure 1 and Figure 4 shown, both sides of the processing table 1 are fixedly installed with left - right adjustment mechanisms 13. Both ends of the side - material cutting mechanism 14 are fixedly installed with infrared sensing modules 15. The moving ends of the two groups of left - right adjustment mechanisms 13 are fixedly installed with front - rear adjustment mechanisms 16. The moving ends of the front - rear adjustment mechanisms 16 are fixedly installed with telescopic mechanisms 17. The side - material cutting mechanism 14 is located directly above the processing table 1. The upper end of the side - material cutting mechanism 14 is fixed to the extending end of the telescopic mechanism 17. The left - right adjustment mechanisms 13 and the front - rear adjustment mechanisms 16 are both in signal connection with the two groups of infrared sensing modules 15. The side - material cutting mechanism 14 and the telescopic mechanism 17 are both in signal connection with the two groups of infrared sensing modules 15.

[0029] The effect achieved by the entire embodiment is as follows: Start the left - right adjustment mechanism 13 and the front - rear adjustment mechanism 16 to operate, so that they drive the two groups of infrared sensing modules 15 to move through the telescopic mechanism 17 and the side - material cutting mechanism 14, which is convenient for the infrared sensing modules 15 to scan the cartons on the processing table 1 and determine the side - materials in the carton printing. After that, the infrared sensing modules 15 will control the left - right adjustment mechanism 13, the front - rear adjustment mechanism 16, the telescopic mechanism 17 and the side - material cutting mechanism 14 to operate. Move the side - material cutting mechanism 14 to the carton side - material position through the left - right adjustment mechanism 13, the front - rear adjustment mechanism 16 and the telescopic mechanism 17, and then cut the carton side - material through the side - material cutting mechanism 14, so as to quickly complete the cutting of the carton side - material.

[0030] Usage method and working principle of this device: First, fix the processing table 1 at the discharge port of the carton printing machine. The printed carton is moved onto the processing table 1 and limited on the processing table 1 by two groups of limiting plates 12. Then, start the operation of the four groups of cylinders 28. The four groups of cylinders 28 drive other structures in the correction mechanism 2 to drive the six groups of push plates 24 to move upward, so that the six groups of push plates 24 move upward respectively inside the six groups of vertical holes 11. After being flush with the limiting plates 12, start the two groups of telescopic rods 22. One of the extending ends of the two groups of telescopic rods 22 drives one of the moving plates 23 to move. One of the moving plates 23 will drive three of the push plates 24 to move, and at the same time will also drive one of the connecting pieces 26 to move, so that one of the connecting pieces 26 drives the movable plate 25 to rotate at the protruding part of the base 21, and the movable plate 25 drives the other connecting piece 26 to move. The other connecting piece 26 drives the other moving plate 23 to move, so that the two moving plates 23 move towards the middle of the base 21. Among them, one end of each of the two connecting pieces 26 rotates on the outer wall of the protruding part of each of the two moving plates 23, and the other end of each of the two connecting pieces 26 rotates on the outer walls of the two protruding parts of the movable plate 25, which facilitates one of the connecting pieces 26 to drive the other connecting piece 26 to move through the movable plate 25, and further enables the two moving plates 23 to drive the six groups of push plates 24 to move, and the six groups of push plates 24 slide respectively inside the six groups of vertical holes 11. Through the cooperation of the two groups of limiting plates 12, the two sides of the carton can be limited, and the carton can be adjusted and corrected. Finally, start the operation of the left-right adjustment mechanism 13 and the front-back adjustment mechanism 16, so that they drive the two infrared induction modules 15 to move through the telescopic mechanism 17 and the side material cutting mechanism 14, which facilitates the infrared induction modules 15 to scan the carton on the processing table 1 and determine the side material in the carton printing. After that, the infrared induction modules 15 will control the operation of the left-right adjustment mechanism 13, the front-back adjustment mechanism 16, the telescopic mechanism 17 and the side material cutting mechanism 14. The side material cutting mechanism 14 is moved to the carton side material through the left-right adjustment mechanism 13, the front-back adjustment mechanism 16 and the telescopic mechanism 17, and then the carton side material is cut by the side material cutting mechanism 14.
