Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical production, in particular to a continuous filling device for pharmaceutical production. Background Technique

[0002] The filling equipment in the field of packaging machinery is increasingly becoming the focus of market attention, and it plays a crucial role in realizing high-quality filling safely and efficiently for the whole production line. With the rapid development of fully automatic technology, remarkable achievements have been made in the field of filling equipment in China. Among them, the linear filling equipment, as a common configuration on the filling line, has shown extensive application value in the filling of paste, powder and granules. Relying on the efficient assembly line operation mode, this equipment simplifies the production filling process and improves the operation efficiency.

[0003] In contrast, the three-dimensional filling equipment mostly adopts the semi-automatic piston filling method, and its technical development level is still not as good as that of the fully automatic equipment. Such equipment extracts and injects materials through the cyclic movement of the piston, and is mainly applicable to the filling of washing liquid, nursing liquid, oral liquid, hair care liquid, hand sanitizer, skin care liquid, disinfectant, liquid foundation, antifreeze, shampoo, eye wash, nutrient solution, injection, pesticide, pharmaceutical products, dishwashing liquid, shower gel, perfume, edible oil, lubricating oil and liquids in special industries.

[0004] However, there are still some problems in the existing technology that need to be solved. Specifically, the filling holes of the current filling equipment are usually located at the head of the catheter, and the catheter is perpendicular to the medicine bottle, resulting in the medicine flowing out of the filling hole vertically with a large impact force, which is easy to generate bubbles in the bottle. As the liquid level of the medicine rises, the bubbles may even overflow outside the bottle, not only causing a large amount of loss of the medicine, but also affecting the cleanliness of the production environment and the quality of the product due to the dripping of the residual medicine after filling. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model
