Filling machinery plays an extremely important role in industrial production and is widely used in the food, chemical, cosmetic, petroleum, and pharmaceutical industries. The world’s first commercial filling machine was born at the end of the 19th century. The application of filling machines has promoted the development of productivity and improved the quality and efficiency of filling. Various industries have also developed filling equipment that meets their own production requirements. , The function is also more perfect. From the single filling at the beginning, it has evolved into a multi-functional filling control technology that integrates the functions of bottle feeding, filling, inspection, capping, and packaging.
There are various types of cosmetics, different types, and different production processes. In cosmetics, there are a large number of paste types. After a series of treatments, the finished products are developed through processes such as color paste insulation and stirring. In recent years, my country's cosmetics filling control technology has developed towards automation, and multiple tasks have been completed simultaneously on the same equipment.
The common structure of cosmetic filling machine is based on the way of filling bottle feeding, including linear filling machine and rotary disc filling machine.
The linear filling machine uses a linear conveyor belt to arrange the cosmetic filling bottles in a row, push the bottle plate to push the filling bottle forward, and push it under the filling pipe. After filling, enter the next one. Process.
The structure of the rotating disc filling machine adopts a disc turntable. On the turntable, a corresponding bottle filling station is set. The conveyor is responsible for sending the filling bottle to the station to complete the filling. After the filling is completed, Send the filling bottle into the conveying mechanism again, and enter the next process.
Taking into account the differences in the chemical and physical properties of the filling materials, in order to ensure the consistency of the filling products, it is necessary to adopt a corresponding filling method. There are several commonly used filling methods:
Atmospheric filling method: Atmospheric filling method is also called pure gravity method. Under normal pressure environment, materials can flow into the packaging container by themselves. Most materials that do not contain gas or liquid can use this type of filling.
Isobaric filling method: Isobaric filling method is also called pressure gravity filling method. When the pressure is higher than atmospheric pressure, the container is restarted to form air pressure, and then the material flows into the container by its own weight.
Vacuum filling method: The vacuum filling method is a method of filling in a sub-atmospheric pressure environment. There are two types of pressure difference vacuum and gravity vacuum. The former means that the liquid storage tank is in a normal pressure environment, and the air is pumped to form a vacuum environment. The liquid material is filled by the pressure difference between the filling container and the liquid storage tank. This filling method is also the most common filling method currently. The latter means that the liquid storage tank is in a vacuum state, the structure is relatively complicated, and it is not used much. In foreign countries, it is mostly used in pesticides, chemical products and other toxic materials.
Siphon method: The siphon method is a filling method based on the siphon principle. This filling method has a long history and simple principle, and is mainly used in the early stages of the development of automated filling technology.
Pressure method: The pressure method is to use other or pressure to fill the material into the packaging container, which is suitable for filling materials with higher viscosity.
