The automatic deviation rectifying and adjusting device 4 comprises a driving mechanism and a belt position detector; the driving mechanism is connected with the roller mounting frame 3 to drive the roller mounting frame 3 to horizontally rotate around the rotating shaft 5, and the belt position detector is installed on the roller mounting frame 3 and connected with the driving mechanism to be used for detecting the position of a belt 7 on the turnabout roller 1 and controlling the driving mechanism to act according to the position of the belt 7.
The belt position detector may be a travel switch, an off-state sensor switch, a pressure sensor switch, a detection wheel, or the like, and the belt position detector may be one or more. The driving mechanism can be an electric push rod, a hydraulic control mechanism, a pneumatic control mechanism, a motor and the like.

For example, when the belt position detector is a travel switch and the driving mechanism is an electric push rod, the belt position detector is electrically connected with a motor of the electric push rod to control the driving mechanism to act.
The deviation rectifying process of the device is as follows:

As shown in fig. 1, for example: assuming that the running direction of the belt 7 is the direction perpendicular to the paper surface and facing inwards, when the belt 7 deviates to the left side of the bend pulley 1, the belt position detector detects the deviation of the belt 7 and then controls the driving mechanism to act, and the driving mechanism drives the pulley mounting frame 3 to horizontally and clockwise rotate for a certain angle around the rotating shaft 5, so that the belt can move towards the center direction (right side). When the belt deviates to the other side, the belt position detector controls the driving mechanism to act, and the driving mechanism drives the roller mounting frame 3 to reversely and horizontally rotate for a certain angle around the rotating shaft 5, so that the belt is always kept at the central position.
In order to facilitate the belt deviation correction, the rotating shaft 5 should be arranged at the central position on the roller mounting frame 3 as much as possible.
The utility model discloses a drum mounting frame rotates through pivot 5 and support frame 2 to be connected, so that 1 ability level deflection of driven pulley, rethread actuating mechanism and belt position detector control driven pulley 1 deflect, in order to prevent the belt off tracking, device convenient to use. In addition, because the turnabout drum is mainly arranged at the head and the tail of the conveyor and plays roles of tensioning and turning the belt of the belt conveyor, the automatic deviation-rectifying adjusting device is arranged on the turnabout drum device, the turnabout drum can more uniformly provide a lateral force for the belt when rectifying deviation, the belt is not easy to deform in the deviation-rectifying process, and therefore the deviation-rectifying effect is better.
When the belt position detector adopts a travel switch, an off-electricity sensing switch or a pressure sensing switch, the sensitivity and the reliability of the deviation correcting device are greatly influenced by the environment. As shown in fig. 3 and 4, for this purpose, it is preferable that the belt position detector includes a first detection wheel 41 and a second detection wheel 42, and the drive mechanism includes a first oil pump 43, a second oil pump 44, an oil tank 46, a pilot operated valve 47, and a hydraulic cylinder 45.

When the pilot control valve 47 is a three-position five-way valve pilot control valve, the first oil pump 43 controls the hydraulic cylinder 45 through the pilot control valve 47 to retract the second oil pump 44 controls the hydraulic cylinder 45 through the pilot control valve 47 to extend as follows:
