AI Technical Summary

Technical Problem

Existing powder packaging technologies suffer from low packaging efficiency and insufficient container positioning accuracy, leading to filling errors that affect product quality and cost.

Method used

A two-stage filling process is adopted, using the first and second feeding devices to perform rapid, high-flow-rate filling and precise compensation respectively. Combined with clamping conveying and adaptive feeding height adjustment, it ensures precise docking between the container and the feeding device and real-time weighing.

Benefits of technology

It improves filling efficiency and weight accuracy, avoids powder leakage and metering errors, and ensures product quality consistency and cost control.

Abstract

本申请公开了一种粉体自动包装工艺，属于粉体包装技术领域，包括：将容器进行粉体灌装直至达到第一设定重量；将容器进行粉体灌装直至达到第二设定重量；在灌注过程中，根据所述容器内的粉体高度实时调节，保持所述第一下料装置的下料高度恒定在所述第一高度区间内；和 / 或，保持所述第二下料装置的下料高度恒定在所述第二高度区间内。第一次灌注可以进行快速、大量灌注，第二次灌注则进行精确、少量补偿，可以有效提高灌注效率及灌注重量精度，确保了称重传感器反馈的真实性与及时性，使得最终灌装重量的控制粒度更细，既解决了单次过量灌注造成的银粉成本溢出，也规避了单次不足引发的客户质量争议。
