The utility model discloses a device for detecting the axial position of a blasting bead in a filter stick, which relates to the field of tobacco detection and is used for quickly detecting the axialposition of the blasting bead in the filter stick. The detection device comprises a detection bench and a projection member. The detection table comprises a shell and a light source arranged in the shell; wherein the shell comprises a working surface, the working surface comprises a detection area, the light source is configured to emit parallel detection light, and the detection area is used forplacing a filter stick. And the projection part is configured to cover one side, deviating from the light source, of the filter stick, so that the detection light projects the filter stick to the projection part. According to the technical scheme, whether the axial position of the blasting bead in the filter stick meets the standard or not is rapidly judged.
