Metering device of tobacco shred feeding machine

The utility model provides a metering device of a tobacco shred feeding machine, and belongs to the technical field of tobacco shred metering. The metering device of the tobacco shred feeder comprises a feeding body, a feeding port, a discharging port, a bottom belt transmission shaft, a feeding bin, a motor, a feeding bin bottom belt and a rotary encoder. Verification tobacco shreds with the first preset weight are weighed in advance and conveyed to the feeding bin from the feeding port, in the process that the bottom belt transmission shaft rotates to convey the verification tobacco shreds in the feeding bin to the discharging port, the rotary encoder counts and obtains the first preset count, and the linear relation between the tobacco shred weight and the pulse count is obtained. Tobacco shreds to be measured are conveyed to the feeding bin from the feeding hopper, the bottom belt transmission shaft rotates, the bottom belt of the feeding bin conveys the tobacco shreds to be measured in the feeding bin to
