Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] In this application, terms such as "upper," "inner," "outer," and "middle" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to specific positions, or to their construction or operation in a specific position.

[0033] like Figure 1-4As shown, a multi-station high-efficiency rotary cutting circular knife die-cutting machine includes a machine body 1, a plurality of supporting legs 2 are evenly connected to the lower end of the machine body 1, a control panel 3 is connected to one side of the machine body 1, and the control panel 3 is connected to the machine body 1 through a hinged bracket 4; the display screen on the control panel 3 can display the machine's working status, cutting parameters, fault alarm and other information in real time, so that the operator can make timely adjustments. A processing table 5 is connected to the machine body 1, and a loading component 6 and a unloading component 7 are respectively provided at both ends of the processing table 5, and the loading component 6 and the unloading component 7 are both rotatably connected to the machine body 1; a plurality of circular knife die-cutting components are evenly connected to the processing table 5, and a tensioning component is provided between the circular knife die-cutting components, and the tensioning component includes an oscillating roller 8, a tensioning roller 11 and a pressing roller 15 connected to the machine body 1 in sequence, and the oscillating roller 8 is rotatably connected to the machine body 1 through a connecting rod 9, and a tension control component corresponding to the connecting rod 9 is connected to the machine body 1. The tension control sensor 10 is provided. The tension roller 11 is longitudinally slidably connected to the machine body 1 via a sliding block 12. The tension roller 11 is rotatably connected to the sliding block 12. The sliding block 12 is threadedly connected to a first screw rod 13. The first screw rod 13 is rotatably connected to the machine body 1. The drive shaft of the first drive motor 14 is connected to the screw rod. The first drive motor 14 is connected to the machine body 1 and is electrically connected to the tension control sensor 10. The pressing roller 15 is rotatably connected to the machine body 1 and is arranged parallel to the tension roller 11. When the tension of the cutting material is insufficient, the swing roller 8 drives the connecting rod 9 to swing slightly. The swing signal of the connecting rod 9 is then transmitted to the tension control sensor 10. The first drive motor 14 is electrically connected to the tension control sensor 10. The first drive motor 14 is then started and drives the sliding block 12 and the tension roller 11 to slide longitudinally on the machine body 1 via the first screw rod 13, thereby adjusting the tension of the material. The tension control sensor 10 then monitors the tension state in real time to ensure that the material maintains a stable tension during the cutting process. The material tension can be adjusted in real time to ensure material stability during the cutting process, thereby improving cutting accuracy. The swing roller 8 and the pressure roller 15 are both detachably connected to the machine body 1; the tensioning roller 11 is also detachably connected to the sliding block 12. Furthermore, the tensioning components adopt a modular design, making them easy to disassemble and replace, allowing for flexible configuration based on different processing requirements.

A dust suction port is provided on the die-cutting table 25, corresponding to the collection box 29, and is connected to a dust collection duct 31. During the cutting process, the cleaning brush 27 brushes away impurities adhering to the circular cutting blade 26, maintaining a clean cut edge. Small impurities removed by the brushing are sucked into the dust collection duct 31 through the dust suction port, and waste and impurities fall into the collection box 29.

The processing table 5 has a slide groove 22 corresponding to the stopper 21. A return spring 23 is connected between the stopper 21 and the slide groove 22. A pressing handle 24 is connected to the stopper 21. In this way, the circular die-cutting assembly can be replaced according to processing requirements. When the circular die-cutting assembly needs to be replaced, the pressing handle 24 controls the stopper 21 to move downward in the slide groove 22, and the die-cutting table 25 can move horizontally along the slide rail 19 on the processing table 5. The return spring 23 ensures that the stopper 21 automatically returns to its original position after being released.

[0038] First, the material to be cut is placed on the loading assembly 6, the cutting material is fed into the processing table 5, and the unloading assembly 7 is adjusted to the ready state. Then, the control panel 3 issues a command to start multiple circular knife die-cutting assemblies to work simultaneously. The cutting circular knives 26 in the circular knife die-cutting assemblies begin to rotate, cutting the cutting material continuously and efficiently.

[0040] At the same time, the position sensor 28 monitors the position deviation of the material during the transmission process in real time. When the position sensor 28 detects the deviation, the position sensor 28 transmits a signal to the second drive motor 18, and then the second drive motor 18 is started, and the correction component 16 is driven by the second screw rod 17 to perform fine adjustment to ensure that the material is in the correct position before cutting.
