corresponding two fixed plates 15 cooperate to stably limit the unlocking sleeve 9 to one side of the reset sleeve 14, so that the unlocking sleeve 9 cannot move, so that the release sleeve 7 cannot move, thereby avoiding accidental unlocking, and ensuring the stability of the fixed structure.

[0042] When the device needs to be used, the external conveying device is above the device, first, the two hydraulic cylinders 34 are synchronously opened, so that the hydraulic cylinders 34 push one end of the conveying frame 4 through the hydraulic rods 35 connected to the output end, since one end of the conveying frame 4 is movably installed on the base 1, the top end of the hydraulic rod 35 is rotatably connected to the other end of the conveying frame 4, and the bottom end of the hydraulic cylinder 34 is movably connected to the base 1, then the conveying frame 4 will gradually be angularly inclined, when adjusted to the appropriate angle, the hydraulic cylinders 34 are closed, then the second motor 30 is opened, the second motor 30 will drive the second transmission roller 31 connected to the output end to rotate, then the second transmission roller 31 will drive the second conveying belt 32 outside the sleeve to run, then the second conveying belt 32 will drive the partition plate 33 outside the setting to move, at the same time, the conveying device outside the device is opened, so that the corrugated paperboard is conveyed to the second conveying belt 32, and the corrugated paperboard is attached to the right side of the partition plate 33, so that the partition plate 33 supports the corrugated paperboard to prevent the corrugated paperboard from being inclined, then the second conveying belt 32 and the partition plate 33 will cooperate to drive the corrugated paperboard to move, when the position of the placing rack 3 is moved, the partition plate 33 will pass through the gap between the placing rack 3 and the limiting rack 2, the corrugated paperboard will be attached to the right side of the placing rack 3, then arranged in turn, neatly vertically stacked, and the upper end surface of the second conveying belt 32 is slightly higher than the placing rack 3, when the placing rack 3 is stacked, the limiting rod is installed on the placing rack 3 through the mounting hole opened on the placing rack 3, so that the placing rack 3 and the limiting rod outside the device clamp and limit the vertically stacked corrugated paperboard, then the hydraulic cylinders 34 are opened again, so that the hydraulic cylinders 34 drive the conveying frame 4 to reset through the hydraulic rods 35, so that the conveying frame 4 is parallel to the ground, so that the corrugated paperboard on the placing rack 3 is vertically placed, then the limiting rack 2 is removed, then the first motor 25 installed on the base 1 is opened, the first motor 25 drives the transmission belt 50 outside the sleeve to run through the transmission wheel 28 connected to the output end, then the transmission belt 50 drives the transmission wheel 28 connected to one end of the first transmission roller 27 to rotate, thereby driving the first transmission roller 27 to rotate, thereby driving the first conveying belt 29 outside the sleeve to run, so that the first conveying belt 29 drives the placing rack 3 and the stacked corrugated paperboard to the left side to the next process, then the empty placing rack 3 is placed on the first conveying belt 29, and the left side of the placing rack 3 is attached to the right side of the limiting rack 2, so that the limiting rack 2 can limit and support the placing rack 3 when the conveying frame 4 is inclined.

[0043] In all the above-mentioned solutions, the connection between the two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection or other known connection mode, which will not be described here. In the above, whenever there is a fixed connection, welding is preferred. Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
