Description

Technical Field

[0001] The utility model relates to the technical field of filling, in particular to an automatic filling machine for chemical reagents. Background Art

[0002] Chemical reagents are relative standard substances for chemical research and component analysis. They are an important condition for scientific and technological progress. They are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. They can be said to be the eyes of chemists. In the daily work of factories, schools, hospitals and research institutes, chemical reagents are indispensable. When chemical reagents are in use, they need to be filled into chemical reagent bottles using filling machines.

[0003] However, the existing automatic filling machines for chemical reagents have the following problems:

[0004] The height of the discharge pipe of the automatic chemical reagent filling machine cannot be adjusted, so it is difficult to reach into the chemical reagent bottle. When the chemical reagent falls into the chemical reagent bottle from a high altitude, a large number of bubbles will be generated, which will affect the filling effect of the chemical reagent.

[0005] Therefore, we make improvements to this and propose an automatic filling machine for chemical reagents. Utility Model Content

[0017] 1. This type of chemical reagent automatic filling machine can drive the first screw rod and the second screw rod to rotate by starting the motor.
