When the workpiece passes through the impregnation assembly, the impregnation piece evenly applies oil liquid to the surface of the workpiece.

[0008] Preferably, the oil dripping device comprises a bottle body for loading oil liquid and a liquid guide pipe connected at one end to the bottom of the bottle body and communicated at the other end with the inside of the impregnation assembly.

[0009] Preferably, the liquid guide pipe is further provided with a flow regulator outside the liquid guide pipe, which is used for adjusting the flow rate of oil liquid in the liquid guide pipe.
