AI Technical Summary

Technical Problem

The weighing signal of liquid products is unstable due to shaking and swaying during the weighing process, making it difficult to achieve accurate detection on high-speed production lines. In addition, existing equipment is costly, complex in structure, and has poor adaptability.

Method used

A floating weighing section and vibration isolation structure are adopted, and a weighing window is generated by photoelectric module triggering. Through steady-state judgment and weight estimation modules, the impact disturbance when liquid products enter and exit the weighing section is avoided, and the influence of conveying vibration on the weighing signal is reduced.

Benefits of technology

It improves the accuracy and stability of liquid product weighing, adapts to the needs of high-speed production lines, reduces equipment costs and structural complexity, and enhances the versatility and flexibility of the equipment.

Abstract

The application discloses a kind of anti-shaking weight-checking devices and systems for liquid product, it is related to the online weight-checking technical field of automatic packaging production line, including support frame, setting on support frame carrier and setting on carrier conveying belt, conveying belt forms the conveying channel for carrying liquid product along conveying direction;Wherein, conveying belt is independently floated in middle part with the weighing section of carrier, weighing section is supported by weighing assembly and is used to output weighing signal;Carrier is set first photoelectric module on the upstream side of weighing section, second photoelectric module is set on the downstream side of weighing section, for respectively output liquid product reaches the trigger signal of upstream position of weighing section and reaches the downstream position of weighing section;And, the downstream side of weighing section and downstream conveying belt are connected to form low-impact transition, so that liquid product is smoothly away from weighing section after weighing is completed, to limit the influence of liquid product in weighing process on weighing signal.
