Storage Structure: It is used to store the hand - washing paste materials to be filled. Usually, it is equipped with a stirring device to prevent the materials from sedimentation, stratification, or adhesion, ensuring the uniformity of the materials.
Feeding Structure: Generally, it is a pressure tank with a liquid - level sensor and a feed solenoid valve. Its function is to put the paste in the storage structure into the tank through the solenoid valve. When the appropriate liquid - level height is reached, the liquid - level sensor sends a signal to control the solenoid valve to close and stop feeding. When the liquid - level in the tank drops to a certain position, the feed solenoid valve can be opened to feed again.
Filling Structure: The paste is fed through a gear pump, and then a piston is pushed by an air cylinder to draw the paste into a container cylinder, which is connected with a check valve in the middle. Then, through the push of the air cylinder, the paste in the container cylinder is pushed back to the filling head through the piston to achieve filling. The filling speed is fast, and the filling quality is high.
Transport Structure: It runs through the connecting part of the entire filling machine. Its main function is to orderly, standardly, and stably transport the filling containers to each filling station. It includes components such as conveyor belts, drive chains, and rollers.
Control System: It is composed of PLC, touch - screen, etc. It can realize functions such as parameter setting, operation control, fault diagnosis, and alarm of the filling machine. For example, it can set the filling volume, filling speed, the number of filling heads, etc., and can also monitor the running status of the equipment in real - time.
Classification by Degree of Automation: There are manual filling machines, semi - automatic filling machines, and fully automatic filling machines. Manual filling machines require manual completion of multiple steps such as feeding, filling, and capping, which are suitable for small - batch production. Semi - automatic filling machines automate some processes, such as the automatic filling process, but still require manual operations such as feeding and capping. Fully automatic filling machines can complete the entire production process of material transportation, filling, capping, labeling, etc. automatically, with high production efficiency, suitable for large - scale production.
Classification by Filling Method: There are atmospheric pressure filling machines, pressure filling machines, and vacuum filling machines. Atmospheric pressure filling machines are suitable for hand - washing pastes with low viscosity and good fluidity, and they fill by gravity under normal pressure. Pressure filling machines quickly fill the paste into the container by applying pressure, which is suitable for high - viscosity hand - washing pastes. Vacuum filling machines first evacuate the filling container to a vacuum state and then suck the paste into the container, which can avoid the generation of bubbles during the filling process and improve the filling quality.
High - Precision Filling: Advanced measurement systems and control technologies are adopted to achieve high - precision filling. The filling error can be controlled within a small range, ensuring that the filling volume of each bottle of hand - washing paste is accurate and consistent.
High - Efficiency Production: Fully automatic filling machines have a high production speed. Equipment with different numbers of filling heads can be selected according to production needs, such as 8 - head, 12 - head, 24 - head, etc. Dozens or even hundreds of bottles can be filled per minute, greatly improving production efficiency.
Versatility: It can adapt to packaging containers of different specifications and shapes, such as plastic bottles, glass bottles, hoses, etc. It can also be customized according to customer needs to meet different production process requirements.
Easy to Operate: It is equipped with a human - machine interface touch - screen. The operation is simple and intuitive. Workers only need to set relevant parameters on the touch - screen, and the equipment can run automatically. At the same time, it also has functions such as fault alarm and display, which is convenient for maintenance personnel to troubleshoot faults in a timely manner.
Hygiene and Safety: The parts in contact with the materials are made of stainless - steel materials or non - toxic plastics that meet food and drug hygiene standards. They are easy to clean and disinfect, preventing the materials from being contaminated and ensuring product quality and safety.
