Hinge, box body and automatic equipment

The invention discloses a hinge, a box body and automatic equipment, and relates to the technical field of rotating engineering elements. The hinge comprises a rotating assembly and an adjusting assembly; the first hinge can rotate synchronously with the rotating shaft, the second hinge is provided with a through containing channel, and the other end of the rotating shaft penetrates through the containing channel; the first damping structure and the second damping structure are both arranged in the containing channel and both arranged on the rotating shaft in a sleeving mode, the first damping structure can synchronously rotate with the rotating shaft, the second damping structure abuts against the first damping structure and can synchronously rotate with the second hinge, and the two ends of the elastic piece abut against the end of the damping piece and the adjusting piece correspondingly. The adjusting piece can move in the direction close to and away from the damping piece. The pressure between the first
