Precise paper moisture detection device

The utility model discloses an accurate paper moisture detection device, which relates to the technical field of paper moisture detection and comprises a workbench, a support seat, a support plate, a movable seat, a detection component, a placement table and a clamping mechanism. By arranging the clamping mechanism, the output end of the electric push rod moves to drive the L-shaped clamping rods to move upwards through mechanical transmission, the sliding block moves to drive the detection assembly to move upwards through mechanical transmission, and then paper is placed between the two L-shaped clamping rods. The output end of an electric push rod resets and moves to drive an L-shaped clamping rod to reset and move through mechanical transmission, a sliding block resets and moves to drive a detection assembly to reset and move through mechanical transmission, through the structure, paper can be limited during paper detection, and the device is also suitable for paper of different thicknesses; and meanwhile,
