Further, a spring is arranged at the lower end of the piston, and the spring is arranged between the dropper and the piston. When the pressure rod is pressed, the pressure rod drives the piston to move downward, and a gap appears between the piston and the dropper at this time, and the lubricating oil in the piston drips onto the moving track through the gap. When the pressure rod is lifted, the spring drives the piston to move upward, and at this time the piston blocks the lower end of the dropper, and the lubricating oil in the oil pot 3 will not drip onto the moving track;

[0035] When the utility model is used, the device is installed on the mobile platform of the palletizer 1. When the mobile platform moves, the mounting frame 2 is driven to move synchronously, thereby driving the roller 7 to rotate along the upper end of the palletizer 1. The rotating roller 7 drives the driven pulley 9 to rotate under the action of the driving pulley 8 and the transmission belt 10. Under the action of the adapter 11, the rotating shaft 16 rotates. When the protruding part of the cam 17 corresponds to the pressing nozzle 5, the cam 17 presses the pressing nozzle 5, so that the lubricating oil in the pressing nozzle 5 drips onto the moving track, thereby realizing the lubrication of the moving track.
