Description

Technical Field

[0001] The present invention relates to the technical field of filling machinery, in particular to a fluid changing filling device. Background Art

[0002] Filling machines are widely used in the filling of pastes and liquids, particularly for toxic or corrosive liquids. Automatic filling can reduce the risk of these liquids to the human body. Currently, filling machines utilize numerical control to implement functions such as quantitative weighing and feeding, automatic line arrangement, and automatic conveying. However, in practice, the same filling machine often needs to fill containers of different models or specifications. Current filling machines have numerous shortcomings. For example, Chinese utility model patent publication number CN205819609U discloses a liquid filling machine that requires manual adjustment of the position of two blade guards, the height of the discharge nozzles, and the width between adjacent discharge nozzles when changing the product. This adjustment requires specialized technicians, and calibration is required after each adjustment. This can lead to a long product change cycle of several hours, which is not only time-consuming and labor-intensive, affecting filling efficiency, but also subject to errors that are difficult to detect due to human error. In particular, due to the varying sizes and specifications of the containers, the guardrails on both sides of the conveyor need to be manually adjusted, impacting filling efficiency.

[0003] Therefore, how to overcome the above-mentioned technical problems and defects becomes a key issue that needs to be solved. Summary of the Invention
