This automatic production line is equipped with relevant high accuracy sensors, under the control of the programmable logic controller (PLC), to conduct testing and monitoring for various parameters such as speed, location, weight, torque, sealing performance etc., to form a closed ring control system. All working position transfers and actions adopt air pressure transmission and control so that it is automation equipment that has integrated optical, mechanic, electric, pneumatic and power components into a whole. This product is mainly composed of below units: supporting roller conveyer, original agent source device, rough filling and fine filling system, vibration filling valve, cylinder valve turning tightly, pressurizing work position, leakage inspection, label sticking or silk tape printing etc, each of which can work as an alone unit, also can be organically combined to generate an automatic production. With manpower saving and high output, each production line needs only 2 or 3 men to complete assembling work. Taking a 4kg fire extinguisher as an example: It can produce 220 products each hour. This company is proud of the production experiences over 50 years. This company can produce various equipment for five extinguisher production based on special requirements from the customers.
