With the popularization of aerosol products, the application range of aerosol filling machines has become more and more extensive. It is not limited to the industrial field, but has expanded to the cosmetics, medicine, food and other industries. However, in design, the aerosol filling machine adopts a fully pneumatic structure, which can not only ensure the safety and health of production, but also save manufacturing costs. Let me introduce to you how the all-pneumatic filling machine works and why the aerosol filling machine is designed like this.
All-pneumatic filling machines are more and more widely used in food packaging and medicine industries. Continuously improving the performance of the filling machine has become an effective way to improve production efficiency. The all-pneumatic filling machine has a faster compressed air flow rate, which makes the pneumatic mechanism The action speed is fast and sensitive. It is easy to realize various relatively complicated action programs by using pneumatic logic elements. Because compressed air is used as the power transmission medium, it is only suitable for outputting not too large external force, which requires the strength of the mechanism. It is relatively low, easy to process and manufacture, and it is very convenient to use cylinders to achieve various linear motions. The pneumatic filling machine has a relatively simple structure and is easy to process and manufacture. The pneumatic mechanism is lubricated by the lubricating oil in the compressed air in the air pipe, valve or cylinder. There is little oil on the outside, which does not pollute the product and can maintain operation. The environment is clean, so it is more and more widely used in food, medicine and cosmetics canning.
An important part of the aerosol filling machine is its pneumatic components, so the performance of the pneumatic components has an important impact on the overall performance of the filling machine. When choosing pneumatic components, one cannot be careless. Quality determines performance.
In the filling machine industry, according to different filling principles, filling machines can be divided into pressure filling machines, atmospheric filling machines, and negative pressure filling machines. Pressure filling is filled at higher than atmospheric pressure. It can also be divided into two types: One is the pressure in the liquid storage tank is equal to the pressure in the bottle, and the liquid flows into the bottle by its own weight to be canned, which is called isobaric canning; the other is the pressure in the liquid storage tank Higher than the pressure in the bottle, the liquid flows into the bottle by pressure difference. This method is often used in high-speed production lines.
The aerosol filling machine also fills according to pressure. The tank is filled with liquid first, then sealed, and then filled with propellant gas by pressure. Since the propellant gas is mostly flammable, explosive and liquefiable gas, it is easy to cause fire. Therefore, in the design, for safety, no electricity is needed. This is another reason why it is designed to be a fully pneumatic filling machine.
