Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of checkweigher, in particular to a high-precision online checkweigher with self-checking function. BACKGROUND

[0002] The checkweigher is a product online checkweighing and sorting equipment applied to packaging production line. The checkweigher is usually integrated with various packaging production lines and conveying systems. When the material is transmitted to the checkweigher on the production line, the high-precision sensor will quickly capture and convert the weight information of the material into an electrical signal, and then transmit the signal to the central processor for real-time analysis. The processor quickly judges the product according to the preset weight standard or quality parameter.

[0003] The existing checkweigher has the following defects: first, the current checkweigher is mostly not equipped with a perfect self-checking system, which means that when the equipment fails or performance declines, it is often impossible to discover and feedback in time. This defect may cause the equipment to continue to run in an abnormal state, which not only affects the accuracy of weighing, but also may interfere with other links on the production line; second, the conveyor belt, as an important part of the checkweigher, its running state directly affects the accuracy of weighing. However, in the existing checkweigher, the conveyor belt is prone to imbalance during operation, such as left and right swing, up and down heave, etc. These imbalances will cause additional vibration and impact force when the product moves on the conveyor belt, thereby affecting the stability and accuracy of the weighing sensor; third, the lack of weighing units for mutual checking makes the equipment lack self-checking and correcting mechanism during weighing. In an ideal checkweigher system, multiple weighing units should be able to check each other to ensure the accuracy and consistency of the weighing result. However, the existing checkweigher is usually equipped with only one weighing unit, which cannot effectively mutual check, which means that even if the weighing unit has errors, the equipment cannot discover and correct itself, thereby increasing the uncertainty of the weighing result.
