Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of die cutting, in particular to an asynchronous die cutting device and process for magnetic wave-absorbing material. BACKGROUND

[0002] Wave-absorbing material refers to a kind of material that can absorb or greatly weaken the electromagnetic wave energy received on its surface, thereby reducing electromagnetic wave interference. In engineering applications, in addition to the requirement that the wave-absorbing material has high absorption rate to electromagnetic waves in a wide frequency band, it also requires light weight, temperature resistance, humidity resistance, corrosion resistance and other properties.

[0003] Magnetic wave-absorbing material has been widely used in electronic communication, household appliances, medical electronic equipment and other fields, but the price of magnetic wave-absorbing material is high, with a few hundred yuan per square meter and thousands of yuan per square meter. In product design, due to the fact that magnetic wave-absorbing material can only be used locally, the loss of raw materials during the processing of magnetic wave-absorbing material is very large, and the cost is also higher. SUMMARY

[0004] The present application provides an asynchronous die cutting device and process for magnetic wave-absorbing material, which can reduce the loss of raw materials during processing and improve the utilization rate.

[0005] To achieve the above purpose, the present application provides the following technical scheme:

[0010] The asynchronous distance is selected according to the specific product. In the process of making wave-absorbing material, when the asynchronous distance is 5mm, the material can be prepared, but it is relatively compact and not conducive to later production. When the asynchronous distance is 15, the material waste is relatively large, which is not conducive to cost saving. Therefore, the preferred asynchronous distance is 11mm.

[0019] The second lamination roller is asynchronous with the second feeding roller b, and the asynchronous interval is 5-15 mm.

[0020] Further,
