Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a die-cutting machine for carton processing. Background Technology

[0002] Die-cutting machines mainly utilize steel blades, hardware molds, and steel wire (or templates carved from steel plates) to apply a certain pressure through a printing plate, cutting printed materials or cardboard into a specific shape.

[0003] In the cardboard box processing, the main process involves fixing an upper pressure plate containing the cardboard box die to a conveyor belt. The cardboard is then fixed above the die, and the conveyor belt moves the upper pressure plate and the cardboard into the die-cutting machine for die-cutting. However, different cardboards require different die-cutting dies, and the upper pressure plate on the conveyor belt of a traditional die-cutting machine cannot be changed quickly. This results in a significant amount of time being spent changing different dies, thus reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a die-cutting machine for cardboard box processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A die-cutting machine for carton processing includes a die-cutting machine and an upper pressure plate. The die-cutting machine consists of a die-cutting table and a die-cutting device. Multiple conveyor belts in the die-cutting table are movably connected to the upper pressure plate. The upper pressure plate is limited and connected to the limiting grooves of the top of the left and right conveyor belts near the front positioning block by limiting posts on the left and right sides of the bottom end.

[0007] A limit rod is fixedly connected to the bottom center of the upper pressure plate via a connecting column. A triangular block is located on the front and back sides of the limit rod via a release spring. Limit blocks for limiting and locking are provided on the left and right sides between the front and back triangular blocks.

[0008] Furthermore, in a preferred configuration, the triangular block located at the rear end of the limiting rod surface is a fixed connection, while the triangular block located at the front end of the limiting rod surface is a movable connection.

[0009] Furthermore, in a preferred configuration, the limiting blocks on the left and right sides are movably connected to the grooves of the fixing blocks on the left and right sides located at the front of the top of the middle conveyor belt via limiting springs.

[0010] In addition, the preferred structure is that the left and right ends of the bottom front side of the upper pressure plate are supported and connected in the support groove by support blocks, and the support groove is located at the top of the left and right conveyor belts.

[0011] Furthermore, a preferred structure is that the front side of the limiting block is provided with an inclined surface with the same inclination as the triangular block.

[0012] In addition, a preferred structure is that multiple conveyor belts are rotatably connected within the die-cutting table via multiple rotating rollers.

[0013] The beneficial effects of this utility model are: by connecting an upper pressure plate with a carton die to the upper limit of the conveyor belt, the cardboard can be die-cut by a die-cutting machine.

[0014] By setting up triangular blocks and limit blocks, the upper pressure plate containing the carton die can be quickly replaced with the die-cutting machine conveyor belt, thereby improving the efficiency of cardboard die-cutting. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figs. 1-2A die-cutting machine for carton processing includes a die-cutting machine 1 and an upper pressure plate 2. The die-cutting machine 1 consists of a die-cutting table and a die-cutting device. Multiple conveyor belts 12 are rotatably connected to the die-cutting table through multiple rotating rollers 11. The upper pressure plate 2 is limited and connected to the upper left side of the top of the multiple conveyor belts 12 by limiting posts 21 on the left and right sides of the bottom end, and is limited and connected to the limiting grooves 14 of the positioning blocks 13 at the top of the left and right conveyor belts 12 by limiting posts 21 on the left and right sides of the bottom end.

[0024] The top front left and right ends of the middle conveyor belt 12 are fixedly installed with fixing blocks 16. The inner side of the fixing block 16 is movably connected to the limiting block 18 through the limiting spring 17 in the groove. The front side of the limiting block 18 is provided with an inclined surface.

[0025] Reference Figs. 4-6 A limiting rod 24 is fixedly connected to the bottom center of the upper pressure plate 2 via a connecting post 23. A release spring 26 connects triangular blocks 25 located on the front and rear sides of the limiting rod 24. The triangular block 25 at the rear end of the limiting rod 24 is fixedly connected, while the triangular block 25 at the front end is movably connected. Furthermore, the left and right ends of the bottom front side of the upper pressure plate 2 are supported and connected to the support groove 15 via support blocks 22. The support groove 15 is located at the top of the left and right conveyor belts 12.

[0026] When the upper pressure plate 2 is connected to multiple conveyor belts 12, the limiting block 18 inside the left and right fixed blocks 16 is located between the front and rear triangular blocks 25, and the inclination of the inclined surface of the triangular block 25 is the same as the inclination of the inclined surface of the limiting block 18.

[0027] In this embodiment, when the cardboard is die-cut, the upper pressure plate 2 containing the carton die is taken out, and then the limiting posts 21 on the left and right sides of the rear end of the upper pressure plate 2 are aligned with the limiting grooves 14 at the top of the positioning blocks 13 on the left and right sides and inserted.

[0028] As the upper pressure plate 2 is pushed in, the connecting post 23 at the rear of the bottom of the upper pressure plate 2 will contact the inclined surfaces of the left and right limit blocks 18. Due to the pushing force, the left and right limit blocks 18 will move into the grooves of the left and right fixed blocks 16 through the limit springs 17. At this time, the connecting post 23 will drive the limit rod 24 and the triangular block 25 on the rear side of the surface of the limit rod 24 to pass through the limit block 18. Then, the left and right limit springs 17 will drive the limit block 18 to reset. At this time, the limit block 18 will be located between the front and rear triangular blocks 25 on the surface of the limit rod 24.

[0029] At this time, the upper pressure plate 2 will be fixed at the top of the multiple conveyor belts 12. The support blocks 22 and support grooves 15 on the left and right sides of the bottom front of the upper pressure plate 2 will play a role in limiting and supporting the upper pressure plate 2.

[0030] The cardboard can then be fixed onto the carton die, and the drive system inside the die-cutting machine 1 drives the conveyor belt 12 to move backward. The conveyor belt 12 drives the upper pressure plate 2 containing the carton die and the cardboard into the die-cutting machine 1. At this time, the cardboard can be die-cut by the die-cutting machine 1 to make it into the unfolded state of the carton. Then the conveyor belt 12 will drive the die-cut cardboard to move backward, and the die-cut cardboard can be taken out.

[0031] When changing the carton die, push the upper pressure plate 2 backward. At this time, the triangular block 25 fixed on the rear side of the limit rod 24 will drive the movable triangular block 25 on the front side to pass through the limit blocks 18 on the left and right sides by releasing the spring 26.

[0032] Then the upper pressure plate 2 can be pushed forward. At this time, by releasing the spring 26, the front triangular block 25 and the rear triangular block 25 will combine to form a similar complete rhombus. Then, the inclined surface of the triangular block 25 will drive the front and rear triangular blocks 25 and the limiting rod 24 to pass through the left and right limiting blocks 18. The limiting blocks 18 will be located in the groove of the left and right fixed blocks 16 by the limiting spring 17. In this way, the upper pressure plate 2 will be separated from the conveyor belt 12. In this way, the upper pressure plate 2 with different carton die-cutting molds can be connected to the conveyor belt 12 through the above operation.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
