Description

Technical Field

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

[0002] In printing and packaging production, precise die-cutting of various materials such as paper and plastic is crucial; in practical applications, die-cutting machines typically require the following technologies:

[0003] 1. Die-cutting mechanisms, such as flatbed die-cutting machines and rotary die-cutting machines, are capable of die-cutting materials into shapes;

[0004] 2. Drive mechanisms, such as high-performance motors and precision transmission devices, provide stable and precise power output for the die-cutting machine, ensuring efficient and accurate die-cutting operations;

[0005] 3. Feeding mechanism, such as an automatic feeding device, ensures accurate material delivery during the die-cutting process.

[0006] Existing Chinese patent: A paperboard rotary die-cutting machine, publication number: CN214981598U, includes a paper feeding mechanism, a transmission mechanism, a die-cutting mechanism, and a fixing mechanism. The back of the paper feeding mechanism is fixedly connected to the transmission mechanism, the back of the transmission mechanism is fixedly connected to the fixing mechanism, and the interior of the fixing mechanism is fixedly connected to the die-cutting mechanism. This utility model solves the problems of unstable paper feeding and lack of precision in existing paperboard rotary die-cutting machines through its paper feeding mechanism, transmission mechanism, die-cutting mechanism, and fixing mechanism.

[0007] However, during the implementation of the above technical solution, at least the following technical problems were found: The above die-cutting machine uses a rotating cutter roller to die-cut the cardboard. Since the cutter is fixedly installed on the cutter roller, it can only cut at a specific position when die-cutting the cardboard. When die-cutting cardboard of different sizes, it is necessary to change the cutter roller with different cutter positions, which is inconvenient to use and increases production costs. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a die-cutting machine that solves the technical problem of die-cutting paperboard by rotating cutter rollers. Because the cutter is fixedly mounted on the cutter roller, it can only cut at specific positions when die-cutting paperboard. When die-cutting paperboard of different sizes, it is necessary to change the cutter roller with different cutter positions, which is inconvenient to use and increases production costs.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A die-cutting machine includes a base, a drive roller rotatably mounted on the base, a first motor fixedly mounted on the side end of the base, a lifting frame for adjusting the cutting height slidably mounted on the base, a bidirectional threaded rod rotatably mounted on the lifting frame, sliding frames symmetrically threaded at both ends of the bidirectional threaded rod, a second motor fixedly mounted on the side end of the lifting frame, a die-cutting blade for cutting the die rotatably mounted on the sliding frames, a drive rod rotatably mounted on the lifting frame, and a tensioning block slidably mounted on the lifting frame. The first motor drives the drive roller to rotate via a bevel gear set, the second motor drives the bidirectional threaded rod to rotate via a bevel gear set, the die-cutting blade and the drive rod are slidably connected, and drive wheels are fixedly mounted on the drive roller, the drive rod and the tensioning block, with a drive belt installed between the three drive wheels.

[0011] Preferably, a first spring is installed on the side end of the tensioning block.

[0012] Preferably, an electric actuator is fixedly installed on the base; the telescopic rod of the electric actuator is connected to the lifting frame.

[0013] Preferably, limit rods are symmetrically slidably mounted on the base; multiple limit rods are symmetrically mounted on both sides of the base, with the two limit rods near the drive roller having equal lengths and the limit rods further away from the drive roller having decreasing lengths.

[0014] Preferably, a limit wheel is rotatably mounted on the limit rod.

[0015] Preferably, a second spring is installed on the limiting rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. If the paper size changes during production and the cutting position needs to be adjusted, the second motor will start. The second motor will drive the bidirectional threaded rod to rotate. Since the bidirectional threaded rod is threadedly connected to the sliding frame, the rotation of the bidirectional threaded rod will cause the sliding frame to slide. The sliding frame will drive the die-cutting blade to slide, thereby changing the cutting position. This achieves the effect of adjusting the cutting position according to production needs and reducing production costs.

[0018] Second, the paper feeding mechanism will deliver the cardboard to the base. At the same time, multiple limiting rods, limiting wheels, and a second spring symmetrically installed on the base will push the cardboard towards the center of the base, ensuring that the centerline of the paper is consistent with the centerline of the base. Finally, two limiting rods of the same length will limit the two ends of the cardboard, ensuring that the edge of the cardboard is parallel to the side of the base. Then, it is fed into the transmission roller for die cutting. The electric push rod can drive the lifting frame to move up and down. The up and down movement of the lifting frame can adjust the cutting depth according to the thickness of the cardboard. During this process, the tension block is pushed by the elastic force of the first spring, and the tension block will keep the transmission belt taut to ensure stable transmission and achieve the effect of adjusting the cutting depth according to the thickness of the paper.

[0027] This application provides a die-cutting machine that effectively solves the technical problem of using a rotating cutter roller to die-cut cardboard. Because the cutter is fixedly mounted on the cutter roller, it can only cut at specific positions. When die-cutting cardboard of different sizes, it is necessary to change the cutter roller with different cutter positions, which is inconvenient and increases production costs. If the paper size changes during production, requiring adjustment of the cutting position, a second motor is activated. The second motor drives a bidirectional threaded rod to rotate. Since the bidirectional threaded rod is threadedly connected to the sliding frame, the rotation of the bidirectional threaded rod causes the sliding frame to slide, which in turn drives the die-cutting blade to slide, thus changing the cutting position. This achieves the ability to adjust the cutting position according to production needs. To reduce production costs, the paper feeding mechanism delivers the cardboard to the base. Simultaneously, multiple symmetrically installed limit rods, limit wheels, and a second spring on the base push the cardboard towards the center of the base, ensuring the centerline of the paper aligns with the centerline of the base. Finally, two limit rods of equal length limit both ends of the cardboard, ensuring the edges of the cardboard are parallel to the sides of the base. The cardboard is then fed onto the transmission rollers for die-cutting. The electric push rod drives the lifting frame to move up and down, adjusting the cutting depth according to the thickness of the cardboard. During this process, the tension block is pushed by the elastic force of the first spring, keeping the transmission belt taut to ensure stable transmission and achieve the effect of adjusting the cutting depth according to the thickness of the paper.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the technical solution in this application embodiment effectively solves the problem of die-cutting paperboard by a rotating cutter roller. Since the cutter is fixedly installed on the cutter roller, it can only cut at specific positions when die-cutting paperboard. When die-cutting paperboard of different sizes, it is necessary to change the cutter roller with different cutter positions, which is inconvenient to use and increases production costs. The overall idea is as follows:

[0030] To address the problems existing in the prior art, this utility model provides a die-cutting machine, including a base 1, a transmission roller 2 rotatably mounted on the base 1, a first motor 3 fixedly mounted on the side end of the base 1, a lifting frame 4 for adjusting the cutting height slidably mounted on the base 1, a bidirectional threaded rod 6 rotatably mounted on the lifting frame 4, sliding frames 5 symmetrically threaded at both ends of the bidirectional threaded rod 6, and a second motor 7 fixedly mounted on the side end of the lifting frame 4.

[0031] A die-cutting blade 8 for cutting the die is rotatably mounted on the sliding frame 5, a transmission rod 9 is rotatably mounted on the lifting frame 4, and a tensioning block 13 is slidably mounted on the lifting frame 4; the first motor 3 drives the transmission roller 2 to rotate through a bevel gear set, and the second motor 7 drives the bidirectional threaded rod 6 to rotate through a bevel gear set. The die-cutting blade 8 and the transmission rod 9 are slidably connected. Transmission wheels 11 are fixedly mounted on the transmission roller 2, the transmission rod 9, and the tensioning block 13, and a transmission belt 12 is installed between the three transmission wheels 11.

[0032] A first spring 14 is installed on the side end of the tensioning block 13, and an electric push rod 15 is fixedly installed on the base 1. The telescopic rod of the electric push rod 15 is connected to the lifting frame 4. Limiting rods 16 are symmetrically slidably installed on the base 1. Multiple limiting rods 16 are symmetrically installed on both sides of the base 1. The two limiting rods 16 near the transmission roller 2 are of equal length, and the length of the limiting rods 16 away from the transmission roller 2 decreases. Limiting wheels 17 are rotatably installed on the limiting rods 16, and a second spring 18 is installed on the limiting rods 16.

[0033] Base 1: As the main structure of the die-cutting machine, it provides a foundation for the installation and support of other components;

[0034] Drive roller 2: Drives the cardboard to move, and is used to assist in the die-cutting operation of the cardboard;

[0035] First motor 3: driving component, drives transmission roller 2 to rotate via bevel gear set;

[0036] Lifting frame 4: Used to adjust the height of the cutting die;

[0037] Sliding frame 5: threadedly connected to the bidirectional threaded rod 6, it slides when the bidirectional threaded rod 6 rotates, thereby driving the die-cutting blade 8 to slide and change the cutting position;

[0038] Bidirectional threaded rod 6: Driven to rotate by the second motor 7, with both ends threadedly connected to two sliding frames 5 respectively. When rotating, it can drive the two sliding frames 5 to slide outward or inward simultaneously.

[0039] Second motor 7: drives the bidirectional threaded rod 6 to rotate in order to adjust the cutting position;

[0040] Die-cutting blade 8: Used for cutting cardboard;

[0041] Transmission rod 9: It is connected to transmission roller 2 via transmission wheel 11 and transmission belt 12;

[0042] Drive wheel 11: serves a transmission function;

[0043] Transmission belt 12: transmits power during the transmission process;

[0044] Tensioning block 13: Under the elastic force of the first spring 14, it keeps the transmission belt 12 taut to ensure stable transmission;

[0045] First spring 14: provides elastic force to tension block 13;

[0046] Electric actuator 15: Its telescopic rod is connected to the lifting frame 4, driving the lifting frame 4 to move up and down to adjust the cutting depth according to the thickness of the cardboard;

[0047] Limiting rod 16: The base 1 has multiple limiting rods 16 on both sides. The two limiting rods 16 on one side that are close to the transmission roller 2 are of equal length, and the length of the limiting rods 16 that are far away from the transmission roller 2 decreases in sequence. They limit and guide the cardboard to ensure that the cardboard is in an accurate position.

[0048] Limiting wheel 17: assists the limiting rod 16 in adjusting the position of the cardboard;

[0049] Second spring 18: Provides elastic force to limit rod 16, so that limit wheel 17 remains in contact with cardboard.

[0050] Working principle:

[0051] In the first step, during use, the paper feeding mechanism will send the cardboard onto the base 1. At the same time, multiple limiting rods 16, limiting wheels 17, and a second spring 18 symmetrically installed on the base 1 will push the cardboard towards the center of the base 1, ensuring that the centerline of the paper is consistent with the centerline of the base 1. Finally, two limiting rods 16 of the same length will limit the two ends of the cardboard, ensuring that the edge of the cardboard is parallel to the side of the base 1. Then, it is fed into the transmission roller 2 for die cutting. The electric push rod 15 can drive the lifting frame 4 to move up and down. The up and down movement of the lifting frame 4 can adjust the cutting depth according to the thickness of the cardboard. During this process, the tension block 13 is pushed by the elastic force of the first spring 14. The tension block 13 will keep the transmission belt 12 taut to ensure stable transmission and achieve the effect of adjusting the cutting depth according to the thickness of the paper.

[0052] In the second step, after the first motor 3 starts, it will drive the transmission roller 2 to rotate. The transmission roller 2 will drive the transmission rod 9 to rotate through the transmission wheel 11 and the transmission belt 12. The transmission rod 9 will drive the die-cutting knife 8 to rotate. The rotating die-cutting knife 8 will die-cut the cardboard. If the size of the paper changes during production and the cutting position needs to be adjusted, the second motor 7 will start. The second motor 7 will drive the bidirectional threaded rod 6 to rotate. Since the bidirectional threaded rod 6 is threadedly connected to the sliding frame 5, the rotation of the bidirectional threaded rod 6 will cause the sliding frame 5 to slide. The sliding frame 5 will drive the die-cutting knife 8 to slide, thereby changing the cutting position. This achieves the effect of adjusting the cutting position according to production needs and reducing production costs.

[0053] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
