[0031] The precision correction control device for the tobacco moisture meter is characterized in that: the turning plate 3 drives the moisture meter main body 5 to be turned up and down, so that the pitch angle of the moisture meter main body 5 is adjusted, the moisture meter main body can detect tobacco at different heights and at different angles, the moisture of the tobacco can be detected from multiple angles or directions, and the accuracy and authenticity of the detection result can be effectively improved.

[0032] Further, the pitch motor 13 is fixedly installed on the adjusting control plate 9 located on the right side of the rectangular groove plate 1, and the output shaft of the pitch motor 13 is coaxially connected with the right end of the horizontal shaft 2. By adopting the scheme, the deflection direction and angle of the moisture meter main body 5 can be controlled by rotating the horizontal shaft through the pitch motor 13, for example, when the pitch motor 13 rotates forward, the turning plate 3, the sliding plate 4 and the moisture meter main body 5 are turned clockwise by the horizontal shaft 2, so that the working part of the moisture meter main body 5 is opposite to the tobacco at a higher position, when the pitch motor 13 rotates reversely, the turning plate 3, the sliding plate 4 and the moisture meter main body 5 are turned counterclockwise by the horizontal shaft 2, so that the working part of the moisture meter main body 5 is opposite to the tobacco at a lower position, so that the tobacco at different positions can be detected, and the detection range is improved; the tobacco at the same position can be detected from multiple angles by adjusting the pitch angle of the moisture meter main body to different angles, so that the accuracy of the detection result can be improved; and the detection angle between the working part of the moisture meter main body 5 and the detected tobacco can be adjusted, so that the tobacco can be detected more accurately.

[0033] Preferably, the two locking screws 11 are respectively threadedly connected with the middle portions of the left and right sides of the turning plate 3; the two circular arc grooves 10 are of the same size and oppositely arranged; and the opening on the rectangular groove plate 1 is a rectangular opening, and the turning plate is a rectangular plate matched with the opening.

For example, when the precision correction motor 14 rotates in the forward direction, the precision correction screw rod 8 rotates in the forward direction through the belt pulley set 15, and then the sliding plate 4 and the moisture meter main body 5 move forward through the precision correction nut 6, so that the moisture meter main body 5 is close to the tobacco. When the precision correction motor 14 rotates in the reverse direction, the precision correction screw rod 8 rotates in the reverse direction through the belt pulley set 15, and then the sliding plate 4 and the moisture meter main body 5 move backward through the precision correction nut 6, so that the moisture meter main body 5 is away from the tobacco. In this way, the distance between the working position of the moisture meter main body 5 and the tobacco can be conveniently adjusted, which is equivalent to the focusing of a camera, so that the tobacco can be detected more accurately, and the detection precision is improved.
