[0020] Working principle: During use, when it is necessary to adjust the spacing between the transmitting grating 1 and the receiving grating 2, the fixing nuts 6 on the fixing studs 5 at the ends of the transmitting grating 1 and the receiving grating 2 are loosened; by adjusting the spacing between the transmitting grating 1 and the receiving grating 2, the width of the light curtain can be adjusted. Due to the different models and specifications of machine tools, the width of the working area may be different; the adjustable width safety light curtain can better adapt to the layout of various machine tools to ensure comprehensive safety protection; the height between the transmitting grating 1 and the receiving grating 2 can be adjusted by starting the switch of the servo electric cylinder 13. By adjusting the height of the light curtain generated between the transmitting grating 1 and the receiving grating 2, it can adapt to machine tool processing tasks of different types and sizes. When processing small parts, the height of the light curtain can be lowered to avoid unnecessary interference; when processing large parts or performing operations at higher positions, the height of the light curtain can be flexibly raised to ensure comprehensive safety protection.
