Description

Technical Field

[0001] The utility model relates to the technical field of carton production equipment, in particular to a die-cutting machine for carton production. Background Technique

[0002] When producing cartons, it is necessary to cut the cardboard into specific shapes to facilitate subsequent splicing of the cartons, so as to improve the convenience during carton production. At the same time, in order to improve the efficiency during carton cutting, a die-cutting device is used to cut the passing cartons to improve the efficiency during carton cutting.

[0003] Generally, during the process of using a die-cutting device to cut cartons, the cutting knife is installed on a roller. By rolling the roller over the passing cartons, the cutting knife can be controlled to cut the passing cartons. However, for different carton models, different lengths of cardboard need to be cut. Since the outer circumference length of the roller is fixed, and at the same time, the positions of the two groups of cutting knives outside the roller are fixed, this results in insufficient length between the two end cutting knives during the cutting of different carton models, thus causing the cut cardboard to be too short and unable to be assembled into a carton, and then causing waste of cardboard due to the gap. For this reason, we propose a die-cutting machine for carton production. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing die-cutting machines for carton production, the utility model provides a die-cutting machine for carton production, which has the advantages of replacing different models of die-cutting rollers according to the size of the cut cardboard, and according to the different diameters of the die-cutting rollers, and by adjusting the positions of the second inclined rod and the auxiliary support rod, different diameters of die-cutting rollers can be limited, thus solving the problems proposed in the above background technique.

[0005] The utility model provides the following technical scheme: A die-cutting machine for carton production, including a conveying box, inside which a conveyor belt is installed through rollers. On both sides of the upper end of the conveying box, brackets are installed. At the upper end of the brackets, four hydraulic rods are installed.

At the same time, an activity sleeve is movably sleeved inside the connecting plate. Inside the activity sleeve, a threaded rod is installed through a bearing. Both ends of the threaded rod are fixedly connected with turning handles. Outside the activity sleeve, a telescopic sleeve is fixedly connected. Inside the telescopic sleeve, eight groups of auxiliary support rods are installed at equal intervals. The outside of the auxiliary support rods is sleeved with die-cutting rollers, and the top end of each group of auxiliary support rods is arranged inside the slide rails opened on the inner side of the die-cutting rollers. A threaded sleeve is movably sleeved inside the threaded rod. The first inclined rod and the second inclined rod are installed inside the activity sleeve and the threaded sleeve through hinges.

[0006] Preferably, telescopic rods are installed on both sides inside the positioning sleeve. A clamping sleeve is fixedly connected to the lower part of the telescopic rod. A roller is installed inside the clamping sleeve, and the roller is arranged at the lower end of the die-cutting roller.

[0007] Preferably, the hydraulic device installed inside the hydraulic rod is arranged at the top of the bracket, and the positioning sleeve is arranged inside the bracket.

[0008] Preferably, the bearing is arranged between the threaded rod and the movable sleeve, and a motor is arranged outside the movable sleeve.

[0009] Preferably, a fastening bolt is installed outside the rotating handle. The fastening bolt passes through the rotating handle and contacts the side surface of the movable sleeve.

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, A die-cutting machine for carton production, including a conveying box 1. Inside the conveying box 1, a conveyor belt 2 is installed through rollers. The conveyor belt 2 drives the movement of the carton's position. On both sides at the upper end of the conveying box 1, brackets 3 are installed. The brackets 3 limit the die-cutting device. At the upper end of the brackets 3, four hydraulic rods 4 are installed. The hydraulic rods 4 control the up and down movement of the die-cutting device to provide power. At the bottom end of the hydraulic rods 4, a positioning sleeve 5 is installed. On the side of the positioning sleeve 5, a connecting plate is installed. At the same time, an activity sleeve 9 is movably sleeved inside the connecting plate. The activity sleeve 9 is arranged at the lower end of the positioning sleeve 5. Inside the activity sleeve 9, a threaded rod 10 is installed through a bearing 11. The bearing 11 reduces the frictional resistance between the threaded rod 10 and the activity sleeve 9. At both ends of the threaded rod 10, a rotating handle 12 is fixedly connected. The rotating handle 12 drives the threaded rod 10 to rotate inside the activity sleeve 9. Outside the activity sleeve 9, a telescopic sleeve 13 is fixedly connected. Inside the telescopic sleeve 13, eight auxiliary support rods 14 are installed at equal intervals. The auxiliary support rods 14 assist in limiting the position of the die-cutting roller 15. The die-cutting roller 15 is sleeved outside the auxiliary support rods 14. The die-cutting roller 15 drives the cutter to perform die-cutting on the carton. And the top end of each group of auxiliary support rods 14 is arranged inside the slide rail opened on the inner side of the die-cutting roller 15. Inside the threaded rod 10, a threaded sleeve 17 is movably sleeved. Inside the activity sleeve 9 and the threaded sleeve 17, a first inclined rod 18 and a second inclined rod 19 are installed through hinges. After the threaded movement between the threaded rod 10 and the threaded sleeve 17, the connection point of the first inclined rod 18 and the second inclined rod 19 can be pushed to move outwards. At the same time, the second inclined rod 19 squeezes and limits the position of the die-cutting roller 15.

[0023] Please refer to Figure 1 , On both sides inside the positioning sleeve 5, telescopic rods 6 are installed. At the lower part of the telescopic rods 6, a clamping sleeve 7 is fixedly connected. Inside the clamping sleeve 7, rollers 8 are installed. And the rollers 8 are arranged at the lower end of the die-cutting roller 15. By controlling two groups of rollers 8 to be arranged on the die-cutting roller 15, the conveyor belt 2 drives the carton to move. At the same time, the rollers 8 are pushed to move downwards under the elastic action of the clamping sleeve 7, that is, the rollers 8 squeeze and limit the position of the carton, ensuring the stability of the carton position during positioning and avoiding the problem that the position of the carton shifts during the process of the die-cutting roller 15 driving the cutter to cut the carton, resulting in affecting the cutting efficiency.

[0024] Please refer to Figure 1 , The hydraulic device installed inside the hydraulic rod 4 is arranged at the top end of the bracket 3. The positioning sleeve 5 is arranged inside the bracket 3. By arranging the positioning sleeve 5 inside the bracket 3 and starting the hydraulic rod 4 at the same time, the hydraulic rod 4 pushes the positioning sleeve 5 to move downwards, and at the same time, the positioning sleeve 5 drives the position of the die-cutting knife to be adjusted.

[0025] Please refer to Figure 5, a bearing 11 is arranged between the threaded rod 10 and the movable sleeve 9. A motor is arranged outside the movable sleeve 9 and is arranged between the threaded rod 10 and the movable sleeve 9 through the bearing 11, that is, the bearing 11 can reduce the frictional resistance when the threaded rod 10 rotates and improve the rotation efficiency of the threaded rod 10.

[0026] Please refer to Figure 5 , at the same time, a fastening bolt 16 is installed outside the rotating handle 12. The fastening bolt 16 passes through the rotating handle 12 and contacts the side surface of the movable sleeve 9. By rotating the fastening bolt 16, the fastening bolt 16 passes through the rotating handle 12, that is, the position of the rotating handle 12 outside the movable sleeve 9 is limited, and the stability of the rotating handle 12 when its position is limited inside the movable sleeve 9 is improved.

[0027] Please refer to Figure 4 , the connection between the first inclined rod 18 and the second inclined rod 19 is interconnected. The outside of the top end of the second inclined rod 19 is arc-shaped. The end of the second inclined rod 19 is in contact with the inner side of the positioning sleeve 5. Rotate the threaded rod 10, and the threaded rod 10 drives the threaded sleeve 17 to perform a threaded movement at the position outside the threaded rod 10. According to the different diameters of the die-cutting roller 15, after adjusting the position of the threaded sleeve 17 by pushing, the connection between the first inclined rod 18 and the second inclined rod 19 drives the connection to extend outwards, that is, the second inclined rod 19 can support from the inner side of the die-cutting roller 15, improving the stability of the die-cutting roller 15 when it is fixed at the position outside the threaded rod 10, and then improving the stability when different-diameter die-cutting rollers 15 are fixed.

[0028] Please refer to Figure 4 , a connecting plate 20 is fixedly connected to the outside of the two groups of movable sleeves 9. A cutting knife is installed outside the die-cutting roller 15. The connecting plate 20 is arranged between the connections of the two groups of first inclined rods 18 and second inclined rods 19. By fixedly connecting the connecting plate 20 to the outside of the movable sleeve 9, the connecting plate 20 limits the movement track of the threaded sleeve 17, avoiding the phenomenon that the position of the threaded sleeve 17 is distorted when the threaded sleeve 17 performs a threaded movement with the threaded rod 10. At the same time, a cutting knife is arranged outside the die-cutting roller 15. When the cutting knife is controlled to contact the cardboard box, the cutting knife can perform die-cutting on the cardboard box.

[0029] Working principle: When in use, place the cardboard box on the upper part of the conveyor belt 2. The conveyor belt 2 drives the cardboard box to be conveyed to the lower part of the die-cutting device. At the same time, according to the different cutting shapes and sizes required, replace the die-cutting rollers 15 of different models. After sleeving the die-cutting roller 15 on the outside of the threaded rod 10, rotate the rotating handle 12. The rotating handle 12 controls the rotation of the threaded rod 10 inside the movable sleeve 9. At the same time, a threaded movement occurs between the threaded rod 10 and the threaded sleeve 17, that is, it pushes the connection of the first inclined rod 18 and the second inclined rod 19 to move outward. That is, the second inclined rod 19 squeezes from the inside of the die-cutting roller 15 to ensure that the die-cutting roller 15 maintains microcomputer performance when its position is limited. And adjust the position of the auxiliary support rod 14 inside the telescopic sleeve 13, that is, the auxiliary support rod 14 assists in limiting the position of the die-cutting roller 15 to ensure the stability of the die-cutting roller 15 when its position is limited. At the same time, start the hydraulic rod 4 and press down the positioning sleeve 5. The positioning sleeve 5 drives the die-cutting roller 15 to contact the cardboard box. That is, during the rolling of the die-cutting roller 15, the passing cardboard box can be die-cut. And when controlling the contact between the die-cutting roller 15 and the cardboard box, the rollers 8 simultaneously squeeze the cardboard boxes on both sides of the die-cutting device to improve the stability of the cardboard box positioning.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
