The invention discloses a medium processing mechanism, a medium processing method and medium processing equipment. The medium processing equipment comprises a medium transmission channel. The medium processing mechanism comprises a main body part, a medium collection mechanism, a sensor and a control component. The main body part is internally provided with a medium accommodating space. The medium collection mechanism is provided with a driving motor and a combing beater. The combing beater is driven to rotate by the driving motor to drive the combing sheets to comb the medium so as to feed the medium into the medium accommodating space. The sensor is used for detecting existence of the medium passing through the medium transmission channel and outputting a detection signal. The control component is used for receiving the detection signal and calculating the number of the media passing through the medium transmission channel according to the detection signal and adjusting the rotating speed of the driving motor according to the number and the preset adjustment rules so as to adjust the number of combing times of each medium. According to the medium processing mechanism, the combing and flapping strength on the media is adjusted according to the passing number of the media so as to consider the flapping strength in case of different number of the media.
