[0028] like Figure 1 As shown, this embodiment provides a palletizer, and the palletizer includes the above-mentioned steering mechanism.

[0029] Working principle of this utility model:

[0030] When it is necessary to add lubricating oil to the steering mechanism of the palletizer, firstly, the cylinder cover 303 is driven to rotate counterclockwise by multiple protrusions 308. When the connecting ring 307 is completely separated from the annular groove, the piston rod 304 is taken out from the oil supply cylinder 301, and then the lubricating oil is poured into the interior of the oil supply cylinder 301. In the process of pouring the lubricating oil into the oil supply cylinder 301, the lubricating oil in the oil supply cylinder 301 will flow into the oil storage cylinder 202 located below through the oil delivery pipe 302 and fill the oil storage cylinder 202. The lubricating oil entering the oil storage cylinder 202 below will soak the oil primer cotton strip 203 and enter the steering mechanism under the guidance of the oil primer cotton strip 203. After pouring the lubricating oil, the piston rod 304 is put back. Into the interior of the oil supply cylinder 301, and rotate the cylinder cover 303 clockwise to complete the assembly work between the cylinder cover 303 and the oil supply cylinder 301 through the connecting ring 307 and the annular groove. During the above process, the piston rod 304 needs to be located above the lubricating oil liquid level, and then the piston rod 304 is driven to move vertically downward by pressing the circular plate 309. During this process, the lubricating oil will flow along the oil hose 305 and finally flow into different oil storage cylinders 202 through multiple branch pipes 306, and then enter the corresponding steering structure under the action of the corresponding oil-introducing cotton strip 203 to complete the lubrication work, which solves the problem that the gap of the steering mechanism is too small and it is not easy to add lubricating oil, and reduces the difficulty of maintenance work of the stacker.
