In the cosmetic, food, pharmaceutical and chemical industries, the packaging of cream products requires a lot of equipment. As a specialized equipment for the packaging of paste materials, the paste filling machine is widely used in the production of all kinds of products with high viscosity such as creams, toothpastes, sauces, ointments and so on. With the diversification of market demand, semi-automatic paste filling machine with its flexibility and economy, become the ideal choice for small and medium-sized enterprises and customized production.

　　First, the working principle of semi-automatic paste filling machine

　　Semi-automatic paste filling machine is mainly composed of storage tank, pneumatic control system, measuring device and filling head. Its working principle is as follows:

　　1. Material storage and transportation: the paste material is firstly stored in the storage tank, and the material is transported to the filling head by pneumatic pump or piston. This process ensures a stable supply of materials, and can control the speed and flow of material delivery by adjusting the pressure.

　　2. Filling metering: Semi-automatic paste filling machine adopts piston or screw type metering, and the volume of each filling is controlled by setting the number of piston strokes or screw rotations. This precise metering system ensures the consistency of the contents of each packaging unit.

　　3. Filling operation: The operator manually places the packaging container (e.g. bottle, tube) under the filling head, activates the filling switch and the material is automatically filled into the container. After the filling is finished, the equipment will stop automatically and wait for the next operation.

　　4. Sealing and Cleaning: Some semi-automatic paste filling machines are also equipped with a simple sealing function for specific packaging needs. At the same time, the equipment is usually designed for easy disassembly and cleaning, in order to replace the material or end of production after a quick cleanup to prevent cross-contamination.

　　Second, semi-automatic paste filling machine features and advantages

　　1. Flexibility: the most important feature of semi-automatic paste filling machine is its operational flexibility. As a result of manual placement of containers and start the filling operation, the equipment can be adapted to a variety of specifications of the packaging containers, suitable for small batch, multi-species production needs.

　　2. Easy to operate: the equipment is designed to be simple, and the operator can get started after simple training. Through the cooperation of pneumatic control and metering system, the filling precision is high and the operation is smooth, which reduces the error and labor intensity of manual operation.

　　3. Economical and practical: Compared with fully automatic equipment, semi-automatic paste filling machine is cheaper, for small and medium-sized enterprises or start-ups, the investment cost is lower, but still can provide high-quality filling results. In addition, the equipment maintenance costs are also lower, outstanding cost performance.

　　4. Strong adaptability: semi-automatic paste filling machine is able to handle paste materials of various viscosities, whether it is thin emulsion or viscous paste, can be adjusted by adjusting the parameters of the equipment to achieve the desired filling effect. This makes it widely used in cosmetics, food, medicine and many other industries.

　　Third, semi-automatic paste filling machine application areas

　　1. Cosmetic industry: in the production of cosmetics, cream, essence, lotion and other products need to be filled with high precision and high hygiene standards. Semi-automatic cream filling machine can meet these requirements, especially suitable for small and medium-sized cosmetic enterprises of small batch production.

　　2. Food industry: semi-automatic paste filling machine is widely used in food processing enterprises, especially suitable for high viscosity food filling such as tomato sauce, peanut butter, honey and so on. The food grade material and convenient cleaning design of the equipment ensure the safety and hygiene of food production.

　　3. Pharmaceutical industry: In pharmaceutical production, the filling of ointments, gels and other creamy drugs requires a high degree of precision and hygiene control. Semi-automatic paste filling machine is able to realize accurate filling of medicines through precise metering and pneumatic control system to ensure the quality of medicines.

　　4. Chemical industry: for some chemical products, such as glue, sealant, lubricants, etc., semi-automatic paste filling machine also outstanding performance. Equipment to adapt to the special viscosity of these materials and filling requirements to ensure smooth production.

　　Fourth, semi-automatic paste filling machine selection and maintenance

　　In the selection of semi-automatic paste filling machine, enterprises should consider the characteristics of the material, production scale, the specifications of the packaging container and filling accuracy and other factors. At the same time, the material of the equipment, easy to clean and the friendliness of the operator interface is also an important criterion for selection.

　　In daily use, the maintenance of semi-automatic paste filling machine is equally important. Regularly check the pneumatic system, metering device and filling head of the equipment to ensure the normal operation of each component. When cleaning, the appropriate cleaning method should be selected according to the characteristics of the material in order to prevent the material residue from affecting the next production.

　　Semi-automatic paste filling machine has become an ideal choice for small and medium-sized enterprises and customized production by virtue of its flexibility, economy, easy operation and other characteristics. With the market demand for diversified, high-quality paste products, semi-automatic paste filling machine in the future production will continue to play an important role in helping enterprises to improve production efficiency and meet customer demand.
