Cleaning device of capsule filling machine and capsule filling machine

The invention discloses a cleaning device of a capsule filling machine. The cleaning device of the capsule filling machine comprises an operation plate, and a reciprocating rectilinear motion device is connected to the operation plate. An air passage is arranged in the operation plate, a hollow connecting pipe downwards communicates with the air passage, a downward pipe brush is connected to the interior of the connecting pipe, and the external diameter of the connecting end of the pipe brush is less than the inner diameter of the connecting pipe. According to the cleaning device of the capsule filling machine, the capsule filling machine can remove wastes and clean manually without halt, so that the production is more fluent, the production efficiency is greatly improved, the loss of materials is reduced, the production cost is greatly reduced, the loading difference quality of products is effectively guaranteed, and meanwhile, the occurrence of pollution and cross contamination riskcaused by manual halt is
