Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical machinery, in particular to a plugging and capping device for medical bottles. Background Technique

[0002] In the current market's vial packaging technology, after the canning process, the main operations are to install leak-proof stoppers and tighten the bottle caps to ensure the product's tightness and integrity. Two mainstream technical solutions are widely adopted in this link: the mechanical positioning cylinder drive system and the cylinder combined with motor control scheme, aiming to efficiently complete the plugging and capping operations, although they each have certain limitations.

[0003] Firstly, there is the device based on the mechanical positioning cylinder. This system uses a component designed in a straight line shape to perform circular and vertical movements at a predetermined angle under the guidance of the positioning cylinder. During this process, using cylinder control and negative pressure technology, one end of this component is responsible for adsorbing the rubber stopper, and the other end adsorbs the bottle cap. The two perform circular movements alternately to achieve precise plugging and capping actions.

[0004] Another widely used method is the combined technology of cylinder plugging and motor-driven capping. In this scheme, after the bottle is positioned, with the linear pushing action of the cylinder, the rubber stopper is precisely placed into the bottle mouth; subsequently, through the rotational movement of the mechanism, the bottle cap is guided and placed on top of the bottle mouth. The subsequent process is then controlled by the motor to complete the final tightening operation of the bottle cap.

[0005] These two technical solutions together exhibit several advantages: simple design and installation, low debugging and maintenance costs, and since they can integrate functions such as canning, plugging, and capping on a single turntable platform, it significantly saves valuable production space. However, they also face efficiency bottlenecks, are difficult to adapt to large-scale production requirements, and are slightly lacking in modular design and flexible expandability, restricting the rapid adjustment and upgrade capabilities of the production line. Therefore, exploring more efficient and highly modular plugging and capping solutions has become an urgent need for the industry's development. Content of the Utility Model
