[0010] like Figure 1 As shown, in this embodiment, an automatic filling device suitable for fire extinguishing agent cylinders includes a transport and positioning mechanism 1, a cap removal mechanism 2, a filling mechanism, and a capping mechanism 5. The transport and positioning mechanism 1 includes a transport rail 11, a positioning mechanism 12 that moves along the rail, and a positioning mechanism driving device. The positioning mechanism 12 is used to limit the movement of the fire extinguishing agent cylinders along the transport rail 11. The positioning mechanism 12 includes a double-layer bottom plate, and the double-layer bottom plate is provided with a plurality of positioning holes for placing the fire extinguishing agent cylinders. The double-layer bottom plate is provided with two rows of positioning holes side by side, respectively placing two rows of fire extinguishing agent cylinders. A plurality of cap removal mechanisms 2 and a plurality of capping mechanisms 5 are provided on both sides of the transport rail 11. The cap removal mechanisms 2 and capping mechanisms 5 located on both sides of the transport rail 11 respectively remove and cap the two rows of fire extinguishing agent cylinders. By simultaneously removing or capping the two rows of fire extinguishing agent cylinders, the filling efficiency is improved.

[0011] The uncapping mechanism 2, the filling mechanism and the capping mechanism 5 are sequentially arranged along the transport slide rail 11. The positioning mechanism driving device drives the positioning mechanism 12 to move to the uncapping station of the uncapping mechanism 2, the filling station of the filling mechanism and the capping station of the capping mechanism 5 in sequence. The uncapping mechanism 2 removes the cap on the filling nozzle of the fire extinguishing agent cylinder located at the uncapping station. The filling mechanism includes a filling fixture 3, a filling nozzle arranged on the filling fixture 3 and a valve screwing mechanism 4. The filling nozzle on the filling fixture 3 is connected to the filling valve group 7. The mounting fixture 3 is used to lift the uncapped fire extinguishing agent cylinder out of the positioning mechanism 12. The valve screwing mechanism 4 is used to open and close the valve of the fire extinguishing agent cylinder. The filling nozzle on the filling fixture 3 is used to connect with the filling nozzle of the fire extinguishing agent cylinder. The filling valve assembly 7 is used to evacuate and fill the fire extinguishing agent cylinder. The filling valve assembly 7 includes a metering pump 6, which is used to measure the refrigerant charged to the fire extinguishing agent cylinder. The filling valve assembly 7 also includes a recovery system 8, which is used to recover the refrigerant charged to the fire extinguishing agent cylinder. The capping mechanism 5 is used to cap the filled fire extinguishing agent cylinder.

[0012] The working process of the automatic filling equipment is as follows: all the filling nozzles of the steel cylinders are adjusted to the same position through the transportation and positioning mechanism 1, and then the caps on the filling nozzles of the steel cylinders are removed through the cap removal mechanism 2. Then all the steel cylinders are sent to the filling station through the transportation and positioning mechanism 1. The filling clamp 3 clamps all the steel cylinders and lifts them to separate the steel cylinders from the positioning mechanism 12. After confirming that the steel cylinders are clamped and lifted, the valve tightening mechanism 4 can simultaneously unscrew all the valves of the steel cylinders, and then the filling nozzles on the clamps are connected to the filling valve group 7. The filling valve group 7 is provided with a metering pump 6 and a recovery system 8. The filling valve group 7 realizes the vacuuming and filling of the steel cylinders, and the filling amount is measured by the metering pump 6. The remaining fire extinguishing agent after the filling is completed is recovered by the recovery system 8, which not only saves the fire extinguishing agent, but also ensures that the fire extinguishing agent does not leak, avoiding environmental pollution. After the filling of the filling valve group 7 is completed, the valve is closed by turning the valve mechanism 4. After all the processes of the filling station are completed, the filling fixture 3 puts all the cylinders back into the positioning mechanism and transports them to the next capping station. The capping process is realized by the capping mechanism 5. At this point, all the processes of this automatic cylinder filling machine are completed.
