Ⅰ,Brief Introduction:
Fire Extinguisher Automatic Filling and Assembling Line invented by our company adopts high precision sensor and programmable Logic Controller (PLC) for control, assuring big capacity and precision production. Our automatic line adopts advanced mechanical technology and Germany or American machine components, assuring long period of using life.
The running of all the work stations and the cooperate between work stations is driven by air pressure. The product line adopts the advanced technology of optics, engine, electricity and air, achieving the high automatic feature.
Our automatic line includes powder tank station, fast filling station, precision filling station, vibration station, valve screwing station, overturn station, pressurizing station, water leak test station.

Ⅲ, Brief introduction of every station
1 Delivery Belt
This part includes delivery belt, controlling cylinder, reducer, front falling and lifting equipment and behind falling and lifting equipment. The purpose of this part is for connecting all the parts, making all the process of production to be continuous and automatic.
2 Powder Frame Station
This station is for powder bag of 1Ton. The powder bag is hanged onto above of powder tank by forklift.
3 Cylinder Weighing Station
This Station is used to calculate the weight of empty cylinder to make it more precise.
4 Fast Filling Station
This part adopts Vacuum jet. The dry powder sucking force is made by the Vacuum of the fire extinguisher cylinder. The filling speed of this part is very high and little error. The setting filling weight is 90% of the total weight. The weighing device would display the data and when the data is the setting data, this part will stop automatically.
5 Precision Filling Station
This part adopts spiral dry powder filling type and the speed is adjustable. It mainly includes the spiral powder feeding machine driven by motor, stainless powder tank, falling and lifting frame, controller. After the finish of rough filling, the fire extinguisher moves to the fine filling part, the blocker makes the precise location, lifting the fire extinguisher and press the lifting and falling button on the main controlling panel, adjusting the distance between the material outlet and fire extinguisher. This part can removing the dust and the dry powder left on the top of the fire extinguisher.
6 Vibration Station
Using the force made by electrical vibration part, this part makes the dry powder filled in the cylinder loose, so it would be easy to put the pipe into the cylinder.
7 Screwing Station
The location of this part is made by electrical proximity switch and blocker and the sensor installed on the fire extinguisher special Chuck make the location of fire extinguisher valve and the air cylinder and motor screw the valve automatically.
8Overturn Station
This station is used to make powder inside cylinder to be loose. In this way, it is easy to filling nitrogen or mixed gas into cylinder.
9 Pressurizing station
This part mainly includes electrical proximity switch, blocker, two lifting and falling equipment, fire extinguisher up clip, gas filling equipment. The pressure gauge and PLC promise the automatic control. All the actions in this part is controlled by cylinder.
