摘要

A sheet type medium thickness identification device comprises a thickness shaft (10), a floating shaft (20) and a sensor (30), wherein two ends of the thickness shaft (10) are installed on two side boards of a frame (40) through bearings, two ends of the floating shaft (20) are installed on the two side boards of the frame (40) through bearings, and the outer surface of the floating shaft (20) contacts tangentially the outer surface of the thickness shaft (10), and the sensor (30) is installed on the front face of the frame and used for detecting the amplitude of the tangential point of the floating shaft (20) and the thickness shaft (10). One end of the thickness shaft (10) is fixedly connected with a first synchronous belt wheel (6), and the first synchronous belt wheel (6) is connected with a first synchronous belt gear wheel (5) through a first synchronous belt (7); one end of the floating shaft (20) is fixedly connected with a second synchronous belt wheel (3), and the second synchronous belt wheel (3) is connected with a second synchronous belt gear wheel (4) through a second synchronous belt (7); and the first synchronous belt gear wheel (5) is meshed with the second synchronous belt gear wheel (4), and assembled on a shaft (81) of a driving motor (8). The thickness identification device avoids the slipping phenomenon between the thickness shaft and the floating shaft. A sheet type medium thickness identification method is also disclosed.
