2. Equipment Overview

The filling container (bottle) is transported to the bottle-feeding place, divided into corresponding intervals, and then fed into the bottle-feeding star wheel. The bottle inlet star wheel moves the bottle to each bottle supporting plate of the filling machine. The bottle mouth is aligned with the center of each filling head, and the filling machine drives each container to rotate together. When the filling valve reaches a certain angle, the filling valve is opened to start filling, and each weighing module measures timely, When the set weight value is reached, the filling valve is closed. The bottle is rotated with the filling machine into the middle star wheel, and then reaches the capping machine. At the same time, the cover is sent to the lid arranging device by the cover lifting machine. It sent to the cover of the distributor. At this time, if a bottle is sent to the capping machine, the capping head will grab (or suck) the lid. According to the curve of the capping cam, the capping arm rises or descends. At the same time, the cap is placed on the bottle mouth and pressed (or tightened) to complete the capping action. Finally, the bottle is sent from the capping machine to the bottle outlet star wheel and then to the bottle delivery chain, thus completing the whole process of filling and capping.

The equipment adopts the technology of weighing and filling, and the filling measurement is accurate. The average filling accuracy of the product can reach the filling positive deviation ≤ 2G.This series of products are widely used in precision filling of large capacity and high value-added liquid materials, such as honey, edible oil, car lubricating oil, brake fluid, high-grade sanitary products. The product application has corresponding configuration and solution.

The filling machine is based on the principle of self-weight filling, and the communication between the electronic weighing device and the external operation panel. Filling machine and capping machine are integrated.
