Description

Technical Field

[0001] This utility model relates to the field of carton die-cutting technology, and more specifically, to a die-cutting mechanism for a carton packaging production line. Background Technology

[0002] Die-cutting of cartons refers to the process of cutting and shaping cartons using a die-cutting machine to produce cartons of specific shapes and sizes. Through the cutting dies and embossing molds on the die-cutting machine, the outer shape and structure of the carton are cut out. Die-cutting is widely used in the packaging industry and can produce cartons of various shapes and styles to meet the packaging needs of different products. The precision and efficiency of die-cutting operations can improve the quality and production efficiency of cartons.

[0003] As in the existing technology CN220075715U, a modular design is adopted, separating the transportation section, the die-cutting section, and the receiving section, so that the three parts do not interfere with each other and cooperate with each other. If the internal parts malfunction, the internal parts can be quickly repaired and replaced, and the internal waste can be quickly collected for easy cleaning. However, the receiving bin in this device is located inside the outer shell, making it inconvenient to observe the condition inside the collection bin, and the die-cut cartons are also prone to falling into the collection bin, causing damage or waste. In view of this, we propose a die-cutting mechanism for a carton packaging production line. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] Please see Figure 1-3 A die-cutting mechanism for a carton packaging production line includes a conveyor belt 1, a die-cutting component 7 above the conveyor belt 1, the die-cutting component 7 being used to cut out the shape and structure of the carton, fixing frames 2 on both sides of the conveyor belt 1, a collection frame 3 at the end of the conveyor belt 1, the collection frame 3 being used to collect the cut-off waste material, and a guiding mechanism 4 above the collection frame 3, the guiding mechanism 4 being provided to prevent the carton from falling into the collection frame 3;

[0024] The guiding mechanism 4 includes multiple guiding rods 401. A mounting rod 402 is positioned below each guiding rod 401. The lower end of the mounting rod 402 is mounted on the edge of the collection frame 3 and can be fixed with bolts. The guiding rods 401 and mounting rods 402 are movably connected, facilitating adjustment of the position of the guiding rods 401 on the mounting rods 402. The guiding rods 401 act as a barrier, preventing cartons from falling into the collection frame 3. A vibration motor 403 is mounted on the mounting rods 402. The output shaft of the vibration motor 403 is connected to the guiding rods 401. The vibration motor 403 drives the guiding rods 401 to vibrate, shaking off waste material from the cartons and improving the efficiency of waste material falling.

[0025] In this application, a movable body 404 is slidably connected to the mounting rod 402. The movable body 404 is designed to facilitate the adjustment of the position of the guide rod 401. The guide rod 401 is configured in two or more sets. The position between two guide rods 401 is adjusted to be less than the width of the carton. The position of the carton is adjusted accordingly for different batches of cartons. The movable body 404 is provided with a mounting groove. The vibration motor 403 is located in the mounting groove. The guide rod 401 slides in the mounting groove and moves vertically when the guide rod 401 vibrates.

[0026] In this application, a drive mechanism is provided on one side of the fixed frame 2. The drive mechanism includes a motor 8, two sets of sprockets 9 and a chain 10. The chain 10 is installed on the inner wall of the conveyor belt 1. Both ends of the conveyor belt 1 are provided with connecting shafts 5. The sprockets 9 are sleeved on the ends of the connecting shafts 5. The output shaft of the motor 8 is connected to one of the connecting shafts 5. The motor 8 drives the connecting shaft 5 and the sprockets 9 on one side to rotate, thereby driving the chain 10 and the conveyor belt 1 that mesh with the sprockets 9 to rotate, and sending the carton on the conveyor belt 1 into the die-cutting assembly 7 for die cutting.

[0027] A support block 6 is provided in the middle of the conveyor belt 1. The support block 6 is slidably engaged with the conveyor belt 1. Protrusions 601 are provided on both sides of the support block 6, and the protrusions 601 are connected and fixed to the fixing frame 2. The support block 6 provides support force to the conveyor belt 1, which facilitates the support of the carton during die cutting. The support block 6 is also connected to the fixing frame 2 through the protrusions 601, which fixes the position of the support block 6.

[0028] In this application, the die-cutting assembly 7 includes a housing 701, a cylinder 702, and a die-cutting cutter 703. The housing 701 is mounted on the top surface of the mounting bracket 2 on both sides. The cylinder 702 is mounted on the top of the housing 701, and a mounting plate 704 is connected to the output shaft of the cylinder 702. The die-cutting cutter 703 is disposed on the bottom surface of the mounting plate 704. The cylinder 702 drives the die-cutting cutter 703 to move vertically to die-cut the carton.

[0029] In this application, guide rods 705 are provided on both sides of the top surface of the mounting plate 704. The guide rods 705 are slidably engaged with the housing 701. The provision of guide rods 705 makes the movement path of the mounting plate 704 more stable.

[0030] In this application, the collection frame 3 is provided with an outwardly extending inclined surface at the entrance on the side near the conveyor belt 1. The inclined surface increases the entrance of the collection frame 3 while preventing waste material from the end of the conveyor belt 1 from falling into the outside of the collection frame 3.

[0031] In this application, baffles can be provided on both sides of the material guiding mechanism 4, and the baffles are connected to the fixing frame 2. The baffles are provided to prevent the cartons from being shaken off. The baffles can also be installed on the side of the mounting rod 402.

[0032] Working principle: When this utility model is in use, the carton is conveyed by the conveyor belt 1. The conveyor belt 1 transports the carton to the die-cutting assembly 7. The cylinder 702 drives the die-cutting cutter 703 to move vertically to die-cut the carton. After die-cutting, the carton continues to be transported backward by the conveyor belt 1. When the carton is transported to the top of the guiding mechanism 4, the waste material falls into the collection frame 3. At the same time, the guiding rod 401 vibrates up and down under the action of the vibrating motor 403, shaking off the waste material on the carton, thereby achieving the effect of separating the waste material from the carton after die-cutting.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
