[0035] As Figures 1-5 shown, it is a schematic diagram of an embodiment of the discharging deviation rectifying device provided by the present utility model.

[0036] Please refer to Figures 1-5 , this embodiment is used for discharging deviation rectification, specifically for the discharging deviation rectification of the plate after the leveling device levels the plate. This embodiment includes a frame 110, a deviation rectifying base 120, and a conveying platform 130.

[0037] The deviation rectifying base 120 is provided on the frame 110, the conveying platform 130 is provided on the deviation rectifying base 120, and the conveying platform 130 is successively provided with a feeding component 131, a feeding component 132, and a discharging component 133.

The telescopic components 1325 are provided on the support frame 1321, and the telescopic ends of the telescopic components 1325 are evenly connected to the upper feeding roller 1323. The term "evenly connected" means that the telescopic components 1325 are equally spaced. The telescopic component can specifically be a cylinder. The upper feeding roller 1323 is located above the lower feeding roller 1322, the lower feeding roller 1322 and the first power component 1324 are provided on the conveying platform 130, and the first power component 1324 drives the lower feeding roller 1322 to rotate.

[0038] Adjust the gap between the upper feeding roller 1323 and the lower feeding roller 1322 through the telescopic member 1325. The upper feeding roller 1323 applies pressure to the upper side of the plate through the telescopic member 1325. The lower feeding roller 1322 contacts the lower side of the plate. The first power member 1324 drives the lower feeding roller 1322 to rotate, thereby driving the movement of the plate. The more uniform the pressure on the upper side of the plate is, the smaller the offset of the plate during movement. By increasing the number of telescopic members 1325, the force application points of the upper feeding roller 1323 are increased, so that the pressure applied by the upper feeding roller 1323 to the plate is more uniform. In theory, the more the number of telescopic members 1325, the more the force application points and the more uniform the force. In this embodiment, 3 telescopic members 1325 are adopted and are respectively arranged at both ends and the middle of the upper feeding roller 1323.

[0039] The conveying platform 130 moves on the deviation rectifying base 120 through the adjusting assembly 140.
