Meanwhile, the whole process is more compact.

When the linear cutting machine is in a non-cutting operation state, the cutting fluid drain pipeline 6 and the cutting fluid output pipeline 8 are controlled to be disconnected, namely, the drain valve and the cutting fluid outlet valve are controlled to be disconnected; so that the cleaning water cannot flow into the cutting fluid output pipeline 8, thereby reducing the possibility of mixing in the cleaning water and spraying out from the spraying device and ensuring the cleanliness of the cutting fluid; the cleaning liquid inlet pipeline 7 is controlled to be conducted (a cleaning control valve is controlled to be conducted) until the cleaning liquid fills the filter cartridge 1 of the cutting liquid circulation system, and then the cleaning liquid inlet pipeline 7 is closed, so that the filter cartridge 1 is ensured to be filled with water during cleaning; controlling ultrasonic operation, wherein the working frequency range is 15 KHz-f-80 KHz, and cleaning the filter screen 2 at a preset frequency.

The preset volume can be a preset volume, and can be set according to the volume of the filter cartridge 1, so that the ultrasonic cleaning assembly has a better cleaning effect on the filter screen 2. Preferably, the cleaning liquid inlet pipeline 7 is controlled to be communicated until the cleaning liquid fills the filter cartridge 1 of the cutting liquid circulation system.

Specifically, the method further comprises the steps of:

judging whether the operation duration of the ultrasonic cleaning assembly is greater than or equal to a second preset duration, if so, executing the next step;

the cleaning liquid inlet pipeline 7 is controlled to be disconnected, the sewage discharge pipeline is controlled to be connected, and the cleaning liquid after cleaning the filter screen 2 is conveyed to a liquid supply device of the wire cutting machine.
