The utility model provides an online filter rod
capsule detection device based on a
microwave method, which relates to the technical field of
cigarette filter rods, comprises a support bracket and a main material
conveyor belt, wherein an auxiliary material
conveyor belt is arranged on the top of the main material
conveyor belt, support brackets are symmetrically arranged on both sides of the main material conveyor belt, a
microwave detection probe is arranged on the top of the support bracket, a detection drum wheel and a transmission drum wheel are respectively connected to the ends of a
servo motor, the detection drum wheel is located on the top of the transmission drum wheel, an air blowing component is arranged between adjacent
servo motors, and limiting arc grooves are circumferentially distributed on the surfaces of the detection drum wheel and the transmission drum wheel, and the
microwave detection probe performs scanning detection, so that unqualified ones can be rejected by the air blowing component and enter the surface of the auxiliary material conveyor belt, and qualified ones can be transported by the transmission drum wheel into the main material conveyor belt for
material distribution and transportation / rejection of defective products, so that the whole device can quickly detect, reject and distribute the filter main body, improve the accuracy and efficiency of the filter main body detection, improve the quality of the filter main body, and facilitate rapid transportation and use.
