Description

Technical Field

[0001] This utility model relates to the field of die-cutting machines, specifically an asynchronous double-seat die-cutting machine. Background Technology

[0002] Die-cutting machines are widely used in industries such as packaging, printing, electronic film, and label production. Their basic principle is to cut rolls or sheets into specific shapes using a die. Traditional die-cutting machines mostly use mechanical transmission for the coordination of punching and material feeding, relying on gears, chains, or cams to achieve synchronized movement. However, mechanical synchronization structures inevitably suffer from wear, clearance, and cumulative errors, leading to insufficient punching accuracy and problems such as punching position misalignment or increased scrap rates.

[0003] Meanwhile, traditional die-cutting machines are typically single-station structures, completing only one die-cutting operation at a time, resulting in low production capacity. In actual production, as product shapes become more complex and precision requirements increase, the shortcomings of existing die-cutting machines in terms of efficiency, precision, and stability become increasingly apparent. Furthermore, due to the rigid limitations of mechanical synchronization, switching between different material specifications requires complex manual adjustments, leading to low automation, high labor intensity, and hindering flexible production.

[0004] In recent years, although some die-cutting machines have begun to introduce servo motors for driving, these improvements are mostly limited to single-stage improvements, such as using servo control only in the material feeding section or only in the stamping section. This improvement fails to solve the matching problem between stamping and material feeding at the system level, and still suffers from defects such as asynchronous movements, low efficiency, and complex control. Especially in multi-station die-cutting scenarios, existing equipment cannot achieve high-precision coordinated control of multiple servo systems.

[0005] Therefore, how to use PLC to coordinate servo stamping and servo drawing in a unified manner to achieve truly high-precision automatic punching and improve the system's flexibility and stability has been a long-standing technical challenge in this field. Utility Model Content

[0006] The purpose of this invention is to provide an asynchronous double-seat die-cutting machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An asynchronous double-seat die-cutting machine includes an electrical box, a control panel, a feeding rack, a stamping assembly, a first asynchronous servo feeding assembly, a feeding shaft, a receiving shaft, a feeding shaft control panel, a second asynchronous servo feeding assembly, a feeding rack, a lower die holder, and an upper die holder;

[0009] The upper die base is located between the first upper asynchronous servo feeding assembly and the second upper asynchronous servo feeding assembly. A material shaft control panel is located at the upper right of the second upper asynchronous servo feeding assembly. A feeding shaft and a receiving shaft are located on the upper left and right sides of the upper die base, respectively. A lower die base is installed at the lower end of the upper die base. A stamping assembly is located between the upper die base and the lower die base. A feeding frame is installed on the right side of the lower die base. A feeding frame is located on the left side of the stamping assembly. A control panel is installed on one side of the feeding frame. An electrical box is located at the lower end of the control panel.

[0010] Preferably, the lower die holder is installed in the middle of the machine body and cooperates with the upper die holder to form a punching station.

[0011] Preferably, the first upper asynchronous servo material pulling component and the second upper asynchronous servo material pulling component are arranged on both sides above the die-cutting machine, and drive the material pulling frame independently to realize dual-station asynchronous material pulling.

[0012] Preferably, the bottom of the asynchronous double-seat die-cutting machine is equipped with a base.

[0013] Preferably, the control panel is connected to the electrical box and is used to control equipment parameters and operating modes.

[0014] Preferably, the electrical box is located on one side of the machine body.

[0015] Compared with existing technologies, this invention has the following advantages: First, in terms of precision, this invention uses a PLC to centrally control the servo stamping motor and the servo drawing motor, ensuring that their movements are synchronized strictly according to the set time logic and displacement parameters, thus avoiding the problems of error accumulation and synchronization failure under mechanical transmission methods. The punching position can remain stable over a long period, greatly improving die-cutting precision.

[0016] Secondly, in terms of efficiency, this invention employs dual-station die-cutting and asynchronous servo control technology. When one die is in the cutting state, the other die can complete the reset and material pulling actions, forming an alternating operation mechanism. This method breaks through the capacity bottleneck of traditional single-station die-cutting machines, achieving a significant increase in efficiency.

[0017] Furthermore, in terms of stability and flexibility, the PLC control system supports parameterized adjustment. Operators can set the punching frequency, drawing length, and synchronization mode according to different materials and product requirements, enabling rapid switching and significantly reducing debugging time. Simultaneously, servo drives replace mechanical transmissions, greatly reducing mechanical wear and vibration, and improving the reliability and service life of the equipment.

[0018] In summary, this invention achieves high-precision, high-efficiency, and high-reliability automatic die-cutting through servo stamping and servo material pulling under PLC control, overcoming long-standing problems in existing technologies and possessing outstanding substantive features and significant progress.

[0022] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0023] Please see Figure 1 An asynchronous double-seat die-cutting machine includes an electrical box 1, a control panel 2, a feeding rack 3, a stamping assembly 4, a first asynchronous servo feeding assembly 5, a feeding shaft 6, a receiving shaft 7, a feeding shaft control panel 8, a second asynchronous servo feeding assembly 9, a feeding rack 10, a lower die holder 11, and an upper die holder 12.

[0024] The upper die base 12 is disposed between the first upper asynchronous servo feeding assembly 5 and the second upper asynchronous servo feeding assembly 9, and a material shaft control panel 8 is disposed at the upper right position of the second upper asynchronous servo feeding assembly 9. The upper left and right sides of the upper die base 12 are respectively located with a feeding shaft 6 and a receiving shaft 7, and a lower die base 11 is installed at the lower end of the upper die base 12. A stamping assembly 4 is disposed between the upper die base 12 and the lower die base 11, and a feeding frame 10 is installed at the right side of the lower die base 11. A feeding frame 3 is disposed on the left side of the stamping assembly 4, and a control panel 2 is installed on one side of the feeding frame 3. An electrical box 1 is disposed at the lower end of the control panel 2.

[0025] The lower die holder 11 is installed in the middle of the machine body and cooperates with the upper die holder 12 to form a punching station.

[0026] Among them, the first upper asynchronous servo material pulling component 5 and the second upper asynchronous servo material pulling component 9 are set on both sides above the die-cutting machine, and drive the material pulling frame 10 independently to realize dual-station asynchronous material pulling.

[0027] The bottom of the asynchronous double-seat die-cutting machine is equipped with a base.

[0028] Control panel 2 is connected to the electrical box and is used to control equipment parameters and operating modes.

[0029] The electrical box 1 is located on one side of the machine body.

[0030] It should be noted that the unloading shaft 6 slowly releases the coil material under the control of the material shaft control panel 8. The coil material is guided into the stamping area by the feeding frame 3. The pulling frame 10, driven by the first upper asynchronous servo pulling component 5 and the second upper asynchronous servo pulling component 9, pulls the coil material forward at a set step distance, and the displacement signal is fed back to the PLC in real time. The PLC determines whether the coil material has reached the punching position according to the set parameters. When it has reached the position, it immediately issues a command to drive the stamping component 4. The upper die holder 12 moves downward under the action of the servo stamping motor, and cooperates with the lower die holder 11 to complete the punching.

[0031] After punching is completed, the upper die holder 12 resets, and the material pulling frame 10 restarts to send the roll material to the next station. Due to the adoption of a dual-seat asynchronous structure, the punching actions of the two stations can be performed alternately: when one station is punching, the other station is resetting and pulling the material, thereby realizing continuous assembly line operation and greatly improving production efficiency.

[0032] Throughout the process, the PLC in control box 1 centrally coordinates the servo motor, material feeding assembly, and material handling system to ensure precise synchronization between stamping and material feeding. Control panel 2 provides parameter setting functions, including material feeding length, stamping frequency, and die-cutting pressure, which operators can flexibly adjust according to material characteristics and product specifications.

[0033] In addition, the present invention also has an automatic tension control function. The rotation speed of the feeding shaft 6 and the take-up shaft 7 can be automatically adjusted according to the tension of the roll material to avoid the material being too loose or too tight and causing deviation, thus ensuring a stable and reliable die-cutting process.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
