Description

Technical Field

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

[0002] With the development of technology in the industrial manufacturing field, drive devices, as the core components for power transmission and motion control, have been widely used in various mechanical equipment. In the field of die-cutting machines, in order to meet the needs of precise cutting and shaping of different materials, drive devices specifically designed to drive die-cutting tools have emerged. These drive devices convert the motion of the power source into the reciprocating motion of the die-cutting tool, thereby realizing the processing of materials.

[0003] In traditional technology, the drive unit of a die-cutting machine generally uses a crank-connecting rod transmission. The crank-connecting rod transmission uses the rotational motion of the crank to drive the connecting rod to perform planar motion, thereby realizing the reciprocating motion of the die-cutting cutter. However, if a single crank-connecting rod is used for power transmission, the rotational motion can easily change the direction of power transmission, affecting the force balance of the cutter during the punching process. This exacerbates the vibration and positional deviation of the cutter, easily leading to uneven cut edges. If multiple crank-connecting rods are used for power transmission, it is difficult to ensure that each crank-connecting rod transmits power simultaneously. Unstable power transmission and asynchronous movement of moving parts make it difficult for the cutter to maintain an absolutely stable and consistent motion trajectory at the moment of die-cutting, which also easily leads to uneven cut edges. There is a technical problem of unstable power output direction of the drive unit, making it difficult to guarantee the punching accuracy of the cutter. Utility Model Content

[0025] like Figure 1 As shown, it is the driving device 100 of this utility model.

[0026] like Figure 1As shown, the drive device 100 includes: a frame 10, a gearbox 20, a transmission mechanism 30, and a drive mechanism 40. The gearbox 20 includes a housing 21, a synchronous pulley 22, and two sets of eccentric pulleys 23. The housing 21 is mounted on the frame 10. The synchronous pulley 22 and each eccentric pulley 23 are rotatably mounted on the housing 21. The synchronous pulley 22 is located between the two sets of eccentric pulleys 23 and meshes with each eccentric pulley 23 to drive each eccentric pulley 23 to rotate synchronously. The transmission mechanism 30 includes a guide rod 3. 2. Mounting platform 31 and transmission arm 33. The mounting platform 31 has a central area 311 and an edge area 312. The central area 311 is rotatably connected to the transmission arm 33. The edge area 312 is arranged around the central area 311 and connected to the guide rod 32. The number of transmission arms 33 corresponds to the number of eccentric wheels 23. The end of each transmission arm 33 away from the mounting platform 31 is rotatably connected to the eccentric shaft of the eccentric wheel 23. There are multiple guide rods 32, and each guide rod 32 is slidably connected to the frame 10. The drive motor... The output end of the mechanism 40 is connected to the synchronous wheel 22 to drive the synchronous wheel 22 to rotate. The synchronous wheel 22 is located between two sets of eccentric wheels 23 and meshes with each eccentric wheel 23 to drive each eccentric wheel 23 to rotate synchronously. The eccentric shaft of the eccentric wheel 23 is rotatably connected to the transmission arm 33. The transmission arm 33 is then rotatably connected to the center area 311 of the mounting table 31. The edge area 312 of the mounting table 31 is connected to the guide rod 32. The guide rod 32 is slidably connected to the frame 10. Through the setting of the synchronous wheel 22, the two eccentric wheels 23 can rotate synchronously, thereby effectively improving the transmission synchronization of each eccentric wheel 23. At the same time, by utilizing the cooperation of the eccentric wheel 23 and the transmission arm 33, under the guidance of the mounting table 31, the circular motion of each eccentric wheel 23 is accurately converted into the linear sliding of the guide rod 32, ensuring the synchronization and stability of the guide rod 32 during transmission, making the force of each guide rod 32 more stable when outputting, and achieving the purpose of improving the punching accuracy of the tool.

[0027] The following text, combined with Figures 1 to 6 The aforementioned drive device 100 will be further described.

[0028] To improve the adaptability and reliability of the drive unit 100, such as Figures 2 to 3As shown, the synchronous pulley 22 includes a synchronous rod 221 and an input gear 222 and an output gear 223 mounted on the synchronous rod 221. The synchronous rod 221 is rotatably connected to the housing 21, the input gear 222 is driven by the drive mechanism 40, and the output gear 223 meshes with each eccentric wheel 23. By adopting the method of rotatably connecting the synchronous rod 221 to the housing 21, driving the input gear 222 to the drive mechanism 40, and meshing the output gear 223 with each eccentric wheel 23, the input gear 222 is driven by the drive mechanism 40, which facilitates receiving power from the drive mechanism 40. The output gear 223 meshes with each eccentric wheel 23, which can efficiently transmit power to the eccentric wheels 23. During the power transmission process, the synchronous pulley 22 can better ensure the stability and consistency of the power, avoid fluctuations and losses in the power transmission process, and achieve the purpose of improving the adaptability and reliability of the drive device 100.

[0029] To improve the operational stability of the eccentric wheel 23 and the comfort of the working environment, such as Figure 3 As shown, the eccentric wheel 23 includes a rotating rod 231 and a transmission gear 232. The rotating rod 231 is rotatably connected to the housing 21. There are two transmission gears 232, which are respectively located on opposite sides of the housing 21 and are both connected to the rotating rod 231. The number of transmission arms 33 is the same as the number of transmission gears 232, and they are rotatably connected to each transmission gear 232 in a one-to-one correspondence. By using two transmission gears 232 respectively located on opposite sides of the housing 21 and both connected to the rotating rod 231, and the transmission arms 33 being rotatably connected to the transmission gears 232 in a one-to-one correspondence, the stability and balance of the transmission are increased. During operation, the two transmission gears 232 participate in the transmission simultaneously, which can effectively share the load and reduce the force on a single transmission component, thereby extending the overall service life of the eccentric wheel 23 and the transmission arms 33. Moreover, since the two transmission gears 232 are symmetrically arranged, the balance of the equipment during operation can be better guaranteed, reducing the generation of vibration and noise, thereby improving the operating stability of the eccentric wheel 23 and the comfort of the working environment.

[0030] To improve the motion accuracy and stability of the drive unit 100, such as Figure 3As shown, the synchronous pulley 22 includes two output gears 223 that mesh with each transmission gear 232. The two output gears 223 are respectively located on opposite sides of the housing 21. The synchronous pulley 22 is provided with two output gears 223 that mesh with each transmission gear 232 and are respectively located on opposite sides of the housing 21, which further enhances the stability and reliability of the transmission between the synchronous pulley 22 and the eccentric pulley 23. By having the two output gears 223 mesh with the transmission gears 232 on both sides, the driving force of the synchronous pulley 22 on the eccentric pulley 23 can be made more uniform, thereby effectively reducing the transmission imbalance that may be caused by unilateral drive, better ensuring the synchronous rotation of the eccentric pulley 23, and effectively applicable to working scenarios with high motion accuracy requirements, thereby achieving the purpose of improving the motion accuracy and stability of the drive device 100.

[0031] To reduce equipment maintenance costs, such as Figures 4 to 5 As shown, the mounting platform 31 includes a connecting plate 35 and an adapter 36. The connecting plate 35 is connected to each guide rod 32, and the adapter 36 is mounted on the connecting plate 35 and rotatably connected to each transmission arm 33. The method of mounting the adapter 36 on the connecting plate 35 and rotatably connecting it to each transmission arm 33 facilitates the installation and adjustment of the position of the transmission arm 33, improving the assembly efficiency and flexibility of the equipment. During the equipment assembly process, the position of the adapter 36 on the connecting plate 35 can be easily adjusted according to actual needs, thereby adjusting the installation angle and position of the transmission arm 33 to adapt to different working requirements. Moreover, this modular design makes the maintenance and replacement of the mounting platform 31 more convenient. If a component malfunctions, it can be repaired or replaced individually, thereby reducing the maintenance cost of the equipment.

[0032] To improve the assembly efficiency of the drive arm 33 and the adapter 36, such as Figures 4 to 5 As shown, the adapter 36 includes a base 361, a rotating shaft 362, and a limiting member 363. The base 361 is mounted on the connecting plate 35 and has a mounting hole. The rotating shaft 362 passes through the mounting hole and connects to the limiting member 363. The transmission arm 33 is rotatably connected to the rotating shaft 362. This configuration, where the base 361 is mounted on the connecting plate 35, the rotating shaft 362 passes through the mounting hole and connects to the limiting member 363, and the transmission arm 33 is rotatably connected to the rotating shaft 362, facilitates the connection between the transmission arm 33 and the mounting platform. In actual use, the assembly of 31 can be carried out by first installing the base 361. After the transmission arm 33 is aligned with the mounting hole of the base 361, the rotating shaft 362 is then controlled to pass through the transmission arm 33, so that the limiting member 363 is connected to the rotating shaft 362 to prevent the transmission arm 33 from disengaging from the rotating shaft 362. This achieves the connection between the transmission arm 33 and the adapter 36, thereby effectively reducing the assembly time of the transmission arm 33 and the adapter 36 and improving the assembly efficiency of the transmission arm 33 and the adapter 36.

[0033] To improve the ease of assembly of the rotating shaft 362, such as Figure 5 As shown, the rotating shaft 362 includes a blocking part 364, a supporting part 365, and a connecting part 366 connected in sequence. The blocking part 364 is located on one side of the base 361. The supporting part 365 has a mounting hole. The connecting part 366 has a limiting groove 367. A limiting member 363 is installed in the limiting groove 367 and is located on the side of the base 361 opposite to the blocking part 364. The rotating shaft 362 comprises the blocking part 364, the supporting part 365, and the connecting part 366 connected in sequence. The blocking part 364 is located on one side of the base 361. The supporting part 365 has a mounting hole. The connecting part 366 has a limiting groove 367. The installation of the limiting member 363 within the limiting groove 367 further optimizes the function of the rotating shaft 362. The blocking part 364 prevents the rotating shaft 362 from falling off the base 361, ensuring the stability of the connection between the rotating shaft 362 and the base 361. The support part 365 provides stable support for the rotating shaft 362, reducing the shaking of the rotating shaft 362 during rotation. The limiting groove 367 of the transition part 366 cooperates with the limiting member 363 to effectively prevent the transmission arm 33 from disengaging from the transition part 366, thereby improving the ease of assembly of the rotating shaft 362.

[0034] To increase the applicability and flexibility of the drive unit 100, improve the working efficiency of the drive mechanism 40, and reduce the energy consumption of the drive mechanism 40, such as Figure 1 and Figure 4 As shown, the drive mechanism 40 includes a drive component 41 and a speed-changing wheel 42. The output end of the drive component 41 is connected to the speed-changing wheel 42. The speed-changing wheel 42 is rotatably mounted on the housing 21 and is connected to the synchronous wheel 22. The drive component 41 is a motor. By connecting the output end of the drive component 41 to the speed-changing wheel 42 and the speed-changing wheel 42 to the synchronous wheel 22, the power output of the drive component 41 can be changed through the cooperation of the speed-changing wheel 42 and the drive component 41 to adapt to different work requirements. In actual work, different work tasks may require the drive device 100 to operate at different speeds and torques. By changing different speed-changing wheels 42, the output parameters of the drive device 100 can be easily changed, thereby increasing the applicability and flexibility of the drive device 100, improving the working efficiency of the drive mechanism 40, and reducing the energy consumption of the drive mechanism 40.

[0035] To improve the power output accuracy of the drive mechanism 40, such as Figure 4As shown, the gearbox 42 includes a gearshift lever 421 and a reduction gear 422. The gearshift lever 421 is rotatably mounted on the housing 21, and the reduction gear 422 meshes with the synchronous pulley 22. The drive unit 41 drives the gearshift lever 421 to rotate via a synchronous belt, thereby driving the reduction gear 422 to rotate. By using the meshing of the reduction gear 422 with the synchronous pulley 22, precise control of the speed of the drive device 100 can be achieved. By adjusting and changing the transmission ratio between the reduction gear 422 and the synchronous pulley 22, precise adjustment of the speed of the synchronous pulley 22 can be achieved. In some working scenarios that require high-precision speed control, more stable and accurate speed control can be provided, ensuring the operating accuracy and stability of the drive device 100, and achieving the purpose of improving the power output accuracy of the drive mechanism 40.

[0036] A die-cutting machine 200 includes a drive device 100 of any of the above-mentioned features. By adopting the drive device 100 of this application, the working accuracy and product quality of the die-cutting machine 200 can be improved. Since the drive device 100 of this application has the advantages of stable transmission, good synchronization and high motion accuracy, it can provide stable and accurate drive for the die-cutting cutter of the die-cutting machine 200, avoiding problems such as die-cutting position deviation and uneven cutting edges caused by unstable drive, thereby achieving the purpose of improving the accuracy and production efficiency of die-cut products.

[0037] When the drive device 100 provided in this application is in use: the drive mechanism 40 is started, the drive component 41 outputs power, driving the speed change wheel 42 to rotate, the speed change wheel 42 transmits power to the synchronous wheel 22, the input gear 222 of the synchronous wheel 22 receives power from the speed change wheel 42, causing the synchronous rod 221 to rotate, which in turn drives the output gear 223 to rotate. Since the synchronous wheel 22 is located between the two sets of eccentric wheels 23 and meshes with the two sets of eccentric wheels 23, it can drive the two sets of eccentric wheels 23 to rotate synchronously. When the eccentric wheel 23 rotates, the eccentric shaft makes a circular motion, which drives the mounting platform 31 to move through the transmission arm 33. Under the action of the transmission arm 33, the mounting platform 31 drives the guide rod 32 to slide linearly on the frame 10, thereby realizing that the drive device 100 converts the rotational motion into linear motion.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
