[0026] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The waste suction knife 210 is provided with a waste suction cavity 211. One end of the waste suction cavity 211 is connected to the negative pressure pipe 220, that is, one end of the waste suction cavity 211 is connected to the internal space of the negative pressure pipe 220, so that the negative pressure environment of the negative pressure pipe 220 can form a suction effect on the waste suction cavity 211. The end of the negative pressure pipe 220 away from the waste suction knife 210 is used to suck the waste. An external negative pressure generating device is connected to form negative pressure on the waste suction chamber 211. The other end of the waste suction chamber 211 is opposite to the cutter structure 110. The plane where the blade of the waste suction knife 210 is located is tangent to the surface of the die-cutting roller 100 it is facing, that is, the extension line of the center axis of the blade of the waste suction knife 210 passes through the axis of the die-cutting roller 100, so that the center axis of the negative pressure airflow formed at the blade of the waste suction knife 210 can be perpendicular to the surface of the corresponding position of the die-cutting roller 100, which can effectively improve the waste suction cleaning effect.

[0034] By arranging a cleaning assembly 200 on one side of the die-cutting blade roller 100, an external negative pressure generating device is connected to the waste suction blade 210 through a negative pressure pipe 220, so that negative pressure can be formed in the waste suction channel 211, and the waste suction channel 211 with negative pressure can form an air suction cleaning effect on the area where the cutter structure 110 is located, and the cut waste in the corresponding area of ​​the cutter structure 110 and the die-cutting blade roller 100 can be cleaned by air suction of the waste suction blade 210, which can effectively improve the structural reliability of the die-cutting blade roller 100 and the cutter structure 110, and can effectively ensure the die-cutting effect and the die-cutting yield rate;

By improving the cleaning effectiveness of the negative pressure airflow, the suction cleaning effect of the negative pressure airflow formed at the blade of the waste suction knife 210 on the die-cutting roller 100 and the cutting knife structure 110 can be effectively improved, thereby further improving the die-cutting performance of the die-cutting roller 100 and the cutting knife structure 110.

[0037] It can be understood that the waste suction chamber 211 is in the shape of a prism, the upper base of the prism refers to the bottom surface of the prism with a small area, the lower base of the prism refers to the bottom surface of the prism with a large area, the lower base of the waste suction channel is away from the side of the waste suction knife 210, and the upper base of the waste suction channel is toward the side of the waste suction knife 210.

[0038] By setting the cross-sectional size of the waste suction channel along the radial path of the die-cutting knife roller 100 to gradually decrease toward one side of the die-cutting knife roller 100, that is, the cross-sectional size of the waste suction channel gradually increases along the forward direction of the airflow, the adsorption force formed at the blade edge of the waste suction knife 210 can be effectively improved, and the suction and cleaning effect of the waste suction knife 210 can be effectively improved.

The two die-cutting rollers 110 are used to clamp sheet materials such as copper foil to achieve die-cutting. Two groups of cleaning components 200 are respectively provided on one side of the two die-cutting rollers 100. The two groups of cleaning components 200 are used to perform suction cleaning on the two die-cutting rollers 100 and the cutting knife structures 110 on their surfaces, respectively, which can ensure the cleanliness of the two die-cutting rollers 100 and the cutting knife structures 110 on their surfaces, and can effectively improve the reliability of the overall die-cutting process.
