Light attenuation detection device for cigarette production line

The invention discloses a light decay detection device for a cigarette production line. The light decay detection device comprises a device main body, a detection probe, a clamping device, a self-walking mechanism, a heat dissipation mechanism and a protective sleeve, the detection probe is arranged on the upper surface of the device body and connected with a circuit arranged in the device body through a wire. The clamping device is clamped to the back face of the device body. The self-walking mechanism comprises a fixed guide rail, a moving wheel, a servo motor and an adjusting wheel, the fixed guide rail is fixedly installed on the production line in advance, the moving wheel is arranged on the fixed guide rail, and the servo motor drives the moving wheel to rotate and move along the fixed guide rail; the servo motor drives the adjusting wheel to rotate to drive the light decay detection device for the cigarette production line to rotate to a preset angle outside the fixed guide rail; the heat dissipation m
