Plugboard type button counting mechanism and counting method

The invention discloses a plugboard type button counting mechanism and counting method. The counting mechanism comprises a front end plate and a rear end plate; and the front end plate and the rear end plate are installed together in a cooperative mode to form a main body. More than one intermediate separation board is fixedly installed between the front end plate and the rear end plate; and thus the space between the front end plate and the rear end plate is divided into more than two button channels; button channel plates are fixedly installed above the button channels; and button inlets are formed in the button channel plates and a button inlet corresponding to each button channel is formed. Photoelectric counters are fixedly installed on the front end plate or the rear end plate; one photoelectric counter is installed at each button channel correspondingly; a counting plugboard cylinder is installed at each button channel correspondingly; and a small counting plugboard is arranged at each button channel and is used for blocking the button channel completely. The counting plugboard cylinders are used for driving the small counting plugboards to move, thereby blocking or opening the button channels.
