Filling machines are machines that achieve the mechanical filling function of materials and are mainly a small category of products in packaging machines. The following is a detailed introduction to filling machines:
Classification:
According to the filling principle:
Atmospheric - pressure filling machines: Filling is carried out by the weight of the liquid under atmospheric pressure. They are divided into two types: timed filling and constant - volume filling. They are only suitable for filling low - viscosity liquids without gas, such as milk, liquor, and mineral water.
Pressure filling machines: Filling is carried out under pressure higher than atmospheric pressure. One type is that the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the liquid flows into the bottle by its own weight for filling, which is called isobaric filling; the other type is that the pressure in the liquid storage cylinder is higher than the pressure in the bottle, and the liquid flows into the bottle by the pressure difference. This method is mostly used in high - speed production lines and is suitable for filling liquids containing gas, such as beer, soda, and champagne.
Vacuum filling machines: Filling is carried out when the pressure in the bottle is lower than the atmospheric pressure. They have a simple structure and high efficiency, and have a wide range of adaptability to the viscosity of materials. They can be used for oils, syrups, fruit wines, etc.
According to the metering method: They can be divided into flowmeter - type, piston - type, weighing - type, etc.
According to the equipment style: They can be divided into linear - type and rotary - type, etc.
Applicable materials: They can be used for filling materials in various forms, such as liquids (such as eye drops, vegetable oils, essential balm, etc.), pastes (such as toothpaste, ointment, various cosmetics, etc.), powders (such as pesticides, veterinary drugs, washing powder, milk powder, etc.), and granular pasty substances (such as granular pasty fluids in industries such as medicine, daily chemicals, food, and pesticides).
Advantages: They can improve the filling efficiency, ensure the filling accuracy, reduce the errors of manual operation, and reduce the labor intensity. They are widely used in industries such as food, beverages, daily chemicals, medicine, and chemical industry.
..., with accurate filling, high efficiency, and the filling dose can be set for automatic filling.
In short, there are various types of filling machines, and users can choose the appropriate filling machines according to their production requirements, material characteristics, etc.
