[0002] After the chain is produced, it needs to be oiled to prevent rust. The existing oiling method is to achieve oiling by dipping. When dipping, one end of the chain is inserted into the oil tank from the inlet of the oil tank, and then the chain is pulled out from the outlet of the oil tank after dipping.
