Description

Technical Field

[0001] The invention relates to the technical field of weight checking equipment, in particular to a high-precision online weight checking equipment with a self-checking function. Background Art

[0002] Checkweighing equipment is a kind of online checkweighing and sorting equipment used in packaging production lines. Checkweighing equipment is usually integrated with various packaging production lines and conveying systems. When the material is transmitted to the checkweigher through 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 parameters.

[0003] The existing weighing equipment has the following defects: First, most of the current weighing equipment is not equipped with a complete self-checking system, which means that when the equipment fails or its performance deteriorates, it is often impossible to detect and feedback in time. This defect may cause the equipment to continue to operate in an abnormal state, which not only affects the accuracy of weighing, but also may interfere with other links on the production line; Second, as an important part of the weighing equipment, the conveyor belt's operating state directly affects the accuracy of weighing. However, in the existing weighing equipment, the conveyor belt is prone to imbalance during operation, such as left and right swings, up and down bumps, etc. These imbalances will cause additional vibration and impact 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 inspection makes the equipment lack a self-checking and correction mechanism during the weighing process. In an ideal weighing system, multiple weighing units should be able to check each other to ensure the accuracy and consistency of the weighing results. However, the existing weighing equipment is often equipped with only one weighing unit, and effective mutual inspection cannot be performed. This means that even if there is an error in the weighing unit, the equipment cannot detect and correct it by itself, thereby increasing the uncertainty of the weighing result.
