Abstract

To address the rapidly growing market demand for manual pressurized toothpaste, the work aims to design and develop a high-precision and reliable fully automatic manual pressurized toothpaste filling machine. A modular architecture was adopted, integrating automatic tube feeding unit, pressurized filling unit, and tail plug sorting unit. An innovative three-stage progressive plugging process combined with air-blowing cutting technology was developed to effectively suppress paste drawing. For toothpaste with a diameter of 39 mm and a weight of 130 g per tube, during a trial production at a rate of 3 000 tubes per hour, the filling error per tube was less than 1%, and the absolute average error was less than 0.5%. This filling machine significantly improves production efficiency and product quality through multi-station synchronous control technology and innovative plugging process, satisfying the production requirements for manual pressurized toothpaste filling equipment and providing technical reference for similar product development.
