At present, the market demand for filter rod forming is constantly increasing, and users have higher and higher requirements for the filter rods themselves. In order to meet market demand and attract consumers, it is necessary to conduct quality inspections on filter rod products during output. Due to the limitations of current equipment and methods, there is a low detection rate, and the end face of the filter rod cannot be fully inspected, nor can defective filter rods be sampled out in time. On the other hand, the fatigue and bad mood of the inspectors after long-term work will also cause defective filter rods to enter the market. Therefore, manufacturers are in urgent need of an efficient and feasible quality inspection device to inspect the end face of the filter rod.

[0021] Preferably, the light source 8 and the camera 9 are coaxially arranged, and the light source 8 is adjustably mounted on the outside of the camera 9 .

[0022] Preferably, the motor is provided with a mounting surface having an elliptical mounting hole formed therein. The support 7 includes a mounting slot for securing the light source 8 and the camera 9, and a fixed connecting plate located at the bottom of the mounting slot. The fixed connecting plate has fixing holes at both ends, and the fixed connecting plate is installed within the fixing holes via screws passing through the fixing holes to achieve a fixed connection between the support and the motor 4.
