Abstract： Aiming at the problem during the cosmetics production process，while the containers need to be cleaned before content filled in，the automatic cleaning device was developed which will be applied in the cosmetics industry. The device is combined with cosmetic filling process and controlled by PLC，while the container be in closure，the circulation formed between vacuum suction which created by the vacuum generator and compressed air blowing，the aim would be reached that the fine hair，fiber and dust be sucked out from the container. The required time analysis which between containers in different sizes，heights and cylinder journey in blowing and sucking was launched. The relationship between the PLC and vacuum generator was established. It was raised that the photoelectric sensor was used，the equipment started working while the sensor responding times reached the setting value. As the evaluating method of cleanness effect，the hair and fine fiber were put in the container in advance and conduct an experiment with 20 000 products was conducted. The results indicate that the device not only has the high degree of automation and excellent effect of container cleaning，but save the production cost and improve operating efficiency.
