AI Technical Summary
Existing laser cutting machine dust covers are prone to developing tiny cracks after repeated use, leading to a decline in protective performance. These cracks are difficult to detect and repair in a timely manner, affecting cutting accuracy.
The dust cover adopts a double-layer telescopic cover structure, forming a sealed space between the inner and outer layers. It uses a one-way air valve and an air pressure gauge to detect air pressure changes. The air pressure changes in the sealed space are used to determine whether the dust cover is damaged.
Timely inspection and maintenance of the dust cover were achieved, ensuring the stability of cutting accuracy and the long-term dustproof effect of the equipment.
