Description

Technical Field

[0001] This utility model relates to the field of die-cutting machines, specifically an in-mold dual asynchronous precision die-cutting machine. Background Technology

[0002] Die-cutting equipment is widely used in industries such as packaging, electronics, automotive parts, and printing. Most traditional die-cutting machines use a single die-cutting method, meaning that material is cut and shaped using a single module. However, as industries demand higher precision, greater diversity, and greater complexity in their products, traditional die-cutting equipment has revealed significant shortcomings in the following aspects:

[0003] Limited die-cutting accuracy: When die-cutting a single module, problems such as uneven cuts and large dimensional deviations are easily generated due to the influence of material pulling stability, mold alignment error and die-cutting stroke. This is especially true in the processing of high-precision electronic films, optical films and other materials, where the errors are more obvious.

[0004] Insufficient efficiency: Traditional die-cutting machines can usually only complete one die-cutting at a single station, making it difficult to achieve asynchronous operation at multiple stations, resulting in low production efficiency and failing to meet the needs of large-scale precision production.

[0005] Simple structure: Existing die-cutting equipment usually adopts a linear structure of "single feeding + single punching". If complex irregular cutting is required, secondary processes or additional equipment are often needed, which increases manual operation and time costs.

[0006] Outdated control methods: Some older die-cutting machines lack a complete control system, and operation relies on manual experience, making it difficult to accurately adjust the punching pressure and die-cutting cycle, which further affects product consistency and yield.

[0007] Therefore, there is an urgent need for an in-mold die-cutting device that is compact in structure, capable of achieving dual asynchronous precision die-cutting, and also takes into account intelligent operation, so as to improve die-cutting accuracy and production efficiency. Utility Model Content

[0008] The purpose of this invention is to provide an in-mold dual asynchronous precision die-cutting machine to solve the problems mentioned in the background art.

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

[0010] An in-mold dual asynchronous precision die-cutting machine includes a feeding rack, an upper die assembly is arranged on the right side of the feeding rack, and a lower die assembly is installed at the lower end of the upper die assembly. A stamping assembly is provided between the upper die assembly and the lower die assembly, and a material pulling rack is installed on the right side of the stamping assembly. A control panel is provided below the feeding rack, and an electrical box is provided at the lower end of the in-mold dual asynchronous precision die-cutting machine.

[0011] Preferably, both the upper and lower modules are equipped with replaceable mold base plates, which are fixed by positioning pins and fastening screws, facilitating quick replacement of molds for different products.

[0012] Preferably, the stamping assembly is a dual-drive structure, including a main stamping unit and a secondary stamping unit, which can perform asynchronous operations to complete precision die-cutting of different parts in the same process.

[0013] Preferably, the feeding frame is equipped with a feeding roller group driven by a servo motor. The feeding roller group can precisely control the step distance and speed of material feeding to match the rhythm of the stamping components.

[0014] Preferably, the control panel is electrically connected to the electrical box, and the control panel is equipped with a touch screen that can display die-cutting parameters, alarm information and production statistics in real time.

[0015] Preferably, the electrical box is equipped with a PLC programmable controller, which is electrically connected to the feeding rack, upper module, lower module, stamping assembly and pulling rack.

[0016] Compared with existing technologies, this utility model has the following advantages: Dual asynchronous die-cutting structure improves processing accuracy: By setting asynchronous actions of the main stamping unit and the auxiliary stamping unit, independent die-cutting of different areas or workstations is achieved, avoiding stress concentration caused by single stamping, resulting in neater cutting edges; Through the PLC control system and touch screen panel, parameter setting, status monitoring, and automatic alarms are realized, making operation more intuitive and reducing reliance on manual labor; Quick mold change improves adaptability: Both upper and lower dies adopt a replaceable mold base plate design, enabling quick mold changes to meet the needs of multi-variety, small-batch, and large-scale production; Cycle time matching and efficiency improvement: The servo motor-driven feeding roller group and stamping components are linked to achieve efficient and precise step feeding, ensuring die-cutting efficiency.

[0017] Other features, objects, and advantages of this application will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0019] In the diagram: 1. Feed rack; 2. Control panel; 3. Electrical box; 4. Lower module; 5. Pulling rack; 6. Stamping assembly; 7. Upper module. Detailed Implementation

[0020] 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.

[0021] Please see Figure 1 An in-mold dual asynchronous precision die-cutting machine includes a feeding rack 1, an upper die 7 is provided on the right side of the feeding rack 1, and a lower die 4 is installed at the lower end of the upper die 7. A stamping assembly 6 is provided between the upper die 7 and the lower die 4, and a material pulling rack 5 is installed on the right side of the stamping assembly 6. A control panel 2 is provided below the feeding rack 1, and an electrical box 3 is provided at the lower end of the in-mold dual asynchronous precision die-cutting machine.

[0022] Both the upper module 7 and the lower module 4 are equipped with replaceable mold base plates. The mold base plates are fixed by positioning pins and fastening screws, which facilitates quick replacement of molds for different products.

[0023] The stamping assembly 6 is a dual-drive structure, including a main stamping unit and a secondary stamping unit. The two can operate asynchronously, thereby completing the precision die-cutting of different parts in the same process.

[0024] The material feeding frame 5 is equipped with a servo motor-driven material feeding roller group, which can precisely control the step distance and speed of material feeding to match the rhythm of the stamping assembly 6.

[0025] The control panel 2 is electrically connected to the electrical box 3. The control panel 2 is equipped with a touch screen that can display die-cutting parameters, alarm information and production statistics in real time.

[0026] The electrical box 3 is equipped with a PLC programmable controller, which is electrically connected to the feeding rack 1, the upper module 7, the lower module 4, the stamping assembly 6, and the pulling rack 5.

[0027] It should be noted that, firstly, the raw material rolls are installed on the feeding rack 1, and the feeding rack 5 plays a crucial role in the feeding process. The feeding rack 5 has a built-in servo motor and roller assembly, which can precisely control the material conveying speed and pitch, ensuring complete consistency with the cycle of the stamping assembly 6. Each feeding pitch is calculated by the PLC controller to avoid deviations caused by manual operation.

[0028] Once the material enters the die-cutting area, the upper die group 7 and the lower die group 4 form a die-cutting station. The stamping assembly 6, consisting of a main stamping unit and a secondary stamping unit, is positioned between them. The PLC system controls the main and secondary stamping units to work alternately or simultaneously according to a preset program, forming a "dual asynchronous" die-cutting mode. For example, while the main stamping unit completes a precision cut of a certain area of ​​the material, the secondary stamping unit can complete cuts of different shapes at another station, thus achieving a highly efficient operation mode of synchronous feeding and asynchronous die-cutting.

[0029] The advantages of this "dual asynchronous" mode are: on the one hand, it avoids material tearing or burrs caused by stress concentration during die cutting; on the other hand, it can complete the cutting of multiple complex shapes in one feeding process, thus improving the overall processing efficiency.

[0030] Throughout the operation, control panel 2 serves as the human-machine interface. The touchscreen displays real-time feeding speed, die-cutting count, production statistics, and alarm information. In case of any abnormalities, such as material shortage, poor die-cutting, or the protective cover being opened, the PLC will immediately issue a command to stop the stamping assembly 6, ensuring the safety of the equipment and operators.

[0031] Electrical box 3 serves as the electrical control center for the entire equipment, housing a PLC controller, relays, power modules, and other electrical components. The electrical box is connected to each actuator via signal and power lines, ensuring coordinated operation and high efficiency and stability of the system.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] 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. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
