Description
Technical Field
[0001] The utility model relates to the technical field of automatic filling mechanisms, in particular to an automatic filling mechanism for oxygen cylinders. Background Art
[0002] The automatic filling mechanism of oxygen cylinders is a device that can fill oxygen into the cylinders. During the operation of the automatic filling mechanism, the control system will first start the conveying system to move the empty container under the filling head, and then open the valve of the filling head through the control system to allow oxygen to flow from the source into the cylinder for filling.
[0003] Before filling the oxygen cylinder, the filling mechanism will use the capping equipment to press the top cover of the oxygen cylinder to the cylinder. Due to the weak structure at the mouth of the tank, the mouth of the oxygen cylinder may be deformed during the capping process. When the deformed cylinder enters the filling area for filling, the oxygen filling may not meet the pressure requirements, resulting in continuous oxygen output and oxygen leakage. Utility Model Content
[0004] The utility model aims to solve the problem that the filling mechanism will connect and compact the top cover of the oxygen cylinder with the cylinder through a capping device before filling the oxygen cylinder. Since the structure at the mouth of the cylinder is relatively weak, the mouth of the oxygen cylinder may be deformed during the capping. When the deformed cylinder enters the filling place for filling, the oxygen filling may not meet the pressure requirement, resulting in continuous output of oxygen and oxygen leakage. An automatic filling mechanism for oxygen cylinders is proposed to solve the problem that the top cover of the oxygen cylinder is connected and compacted with the cylinder through a capping device before filling. Since the structure at the mouth of the cylinder is relatively weak, the mouth of the oxygen cylinder may be deformed during the capping. When the deformed cylinder enters the filling place for filling, the oxygen filling may not meet the pressure requirement, resulting in continuous output of oxygen and oxygen leakage.
