■ Product Overview
The Rotary Bottle Checkweigher is a high-speed, high-precision online weighing device, mainly used for weight detection and sorting of continuously flowing bottled or canned products on the production line.
●Product Infeed:
Products (bottles/cans) to be inspected enter the machine via a feed conveyor belt.
A feed star wheel (or guide screw) guides the products onto the checkweighing turntable at equal intervals and a stable speed.
●Dynamic Weighing:
Products are placed on an independent weighing platform/pan on the checkweighing turntable.
As the platform moves above a high-precision load cell, the sensor collects and calculates the product’s weight in a very short time, even while the product is moving at high speed.
The checkweigher’s control system quickly compares the actual measured weight with a preset standard weight range (upper and lower limits).
●Judgment and Rejection:
Based on the weighing results, the control system makes the following judgments:
If the weight is within the standard range, the product continues to move with the turntable to the discharge port and proceeds normally to the next process.
For defective products, when the product moves to a specific rejection station, a rejection device (such as a pusher or air blower) quickly and accurately separates it from the production line and places it in a collection bin.
●Data Statistics:
The equipment performs real-time statistics on test data, such as the number of qualified products, the number of unqualified products, average weight, standard deviation, etc., so that operators can monitor the filling accuracy of the production line.

■ Main Features
1. High Efficiency/High Speed: Utilizing a rotary/star wheel structure, it enables high-speed continuous conveying and weighing of products, making it ideal for high-volume, high-output production lines.
2. High Precision: Employing highly sensitive weighing sensors and advanced digital filtering algorithms ensures accurate dynamic weighing.
3. Stability: The stable mechanical structure ensures products are firmly gripped or supported on the rotary table, reducing vibration and errors caused by high-speed movement.
4. Non-Destructive Testing: Online weighing does not affect the normal flow and packaging of products.
■ Application
Checkweighers are primarily used in industries requiring high-speed, precise weight control for bottled, canned, or cylindrical containers:
Food and Beverage: Beverage bottles, condiment bottles, canned goods, wine bottles, etc.
Pharmaceuticals: Medicine bottles, infusion bottles, health supplement bottles, etc.
Chemicals: Shampoo bottles, cosmetic bottles, detergent bottles, etc.
