Double-sheet detection device

A double-sheet detection device, comprising a paper feeding machine body (1), wherein a main body plate (2) is arranged on an outer side of the paper feeding machine body (1);

• a detection mechanism (3) is arranged on an inner side of the main body plate (2);
• the paper feeding machine body (1) is provided with a storage assembly (4);
• the detection mechanism (3) comprises a U-shaped plate (31);
• the U-shaped plate (31) is arranged on the inner side of the main body plate (2);
• an inner side top of the U-shaped plate (31) is fixedly connected with a first damper (32);
• a bottom of the first damper (32) is fixedly connected with a detection wheel (33);
• an angle sensor (374) is mounted on the detection wheel (33);
• a first spring (34) is fixedly connected to an exterior of the first damper (32);
• a top and bottom of the first spring (34) are fixedly connected with the inner side top of the U-shaped plate (31) and a top of the detection wheel (33), respectively;
• a rear side of the U-shaped plate (31) is fixedly connected with a transverse plate (35);
• a movement slot (36) is formed in the transverse plate (35);
• an interior of the movement slot (36) is connected with a movable block (37);
• the movable block (37) penetrates through the movement slot (36);
• a bottom of the movable block (37) is fixedly connected with a first electric telescopic rod (38);
• a bottom of the first electric telescopic rod (38) is fixedly connected with an auxiliary plate (39);
• a bottom of the auxiliary plate (39) is fixedly connected with a circular tube (391);
• and a bottom of the circular tube (391) is fixedly connected with a suction cup (392);
• wherein the angle sensor (374) is coaxially connected to the detection wheel (33);
• when a material passes, the angle sensor (374) is driven by a rotating shaft;
• real-time data of the angle sensor (374) is obtained by high-speed communication with the angle sensor (374);
• and an actual thickness value of the material is calculated through an algorithm.
