[0002] In the pharmaceutical manufacturing industry, drug solution filling is a crucial step, directly related to product quality and production efficiency. With the development of the pharmaceutical industry, the requirements for drug solution filling mechanisms are also increasing. Not only do they require high filling accuracy and fast filling speed, but they also need to have good stability and reliability to meet the filling needs of different types and viscosities of drug solutions.

[0003] In the prior art, liquid medicine is usually filled using a secondary polishing machine, such as calcium gluconate injection. The secondary polishing machine is provided with a conveying mechanism and a filling mechanism. The filling mechanism is located above the conveying mechanism. When the conveying mechanism conveys the packaging bag to the bottom of the filling mechanism, the filling mechanism can move down with multiple filling gun heads to fill the liquid medicine.

[0004] Although the above-mentioned secondary polishing machine can fill liquid medicine, if a single filling production line is to complete the production task of different liquid medicines, it is necessary to connect the filling needle corresponding to the liquid to be replaced to different liquid tanks after producing a batch of liquid medicines and filling and packaging. Moreover, before filling, the residual liquid in the filling needle needs to be flushed. The operation process is cumbersome and inefficient, and there is also the possibility of mixing liquids and causing product contamination. Based on the above reasons and actual production needs, we want to design a filling needle switching mechanism to achieve the purpose of quickly adjusting the filling of different liquid medicines on a single filling production line.
