Technical Field

[0001] The present invention relates to the technical field of medicine packaging, and in particular to a liquid medicine pharmaceutical packaging process and equipment. Background Art

[0002] Liquid medicine refers to a liquid medicine made by dispersing drugs in a suitable dispersion medium. It can be taken orally or externally. The drugs in the liquid medicine can be dispersed in the medium in a molecular state or a particle state, thus forming a homogeneous liquid medicine or a heterogeneous liquid medicine. The degree of dispersion of drug particles in the liquid medicine is closely related to the efficacy, stability and toxic side effects of the medicine. Different preparation methods are required for liquid medicines in different dispersion states.

[0003] When packaging eye drops, the packaging bottles must be placed and transported first, and then filled with the medicine one by one. However, the packaging bottle conveying and placing devices in the prior art are mostly only suitable for packaging bottles of a single specification and model. When used for packaging medicine bottles of different specifications, the placing plate needs to be disassembled and replaced as a whole, which is very troublesome and not conducive to production and processing. In addition, the packaging bottles are prone to tipping over during transportation. When filling, it is inconvenient to adjust the amount of filling medicine according to the specifications of the packaging bottles, resulting in inconvenience in processing. Therefore, it is necessary to propose a liquid medicine pharmaceutical packaging process and equipment to solve the above problems. Summary of the invention
