AI Technical Summary

Technical Problem

In the existing technology, the separation of weighing and packaging in the workpiece packaging process makes it difficult to maintain stable accuracy, making it impossible to achieve accurate automatic unloading of the rated weight, affecting efficiency and weight consistency, and relying heavily on manual labor, which poses a risk of overloading or underloading.

Method used

This integrated weighing and heat-sealing packaging equipment uses a gravity sensor and a gravity discharge component to detect the weight of the workpiece in real time. The gravity sensor controls the gravity discharge component to automatically discharge the workpiece of the rated weight and transport it to the heat-sealing packaging device for heat sealing and packaging.

Benefits of technology

This has improved the weight accuracy and consistency of workpiece packaging, avoided overweight or underweight issues, increased production efficiency, reduced labor costs and labor intensity, and ensured the stability and intelligence level of packaging quality.

Abstract

This invention relates to the field of workpiece packaging technology, specifically to an integrated weighing and heat-sealing packaging device and method. It includes a heat-sealing packaging apparatus and a weighing device. The weighing device comprises a weighing shell, a weighing inlet, a weighing outlet, and a discharge weighing mechanism. The weighing outlet corresponds to the inlet of the heat-sealing packaging apparatus. The discharge weighing mechanism includes a vibrating discharge component, a discharge cylinder, a discharge ramp, and a gravity sensor located at the bottom of the discharge ramp. The discharge ramp extends to the outside of the weighing outlet. The discharge end of the discharge cylinder is equipped with a gravity discharge component that works in conjunction with the gravity sensor. When a workpiece vibrating down onto the discharge ramp reaches the rated weight of the gravity sensor, the gravity discharge component controls the discharge of the workpiece. This patent, through the cooperation of the heat-sealing packaging device and the weighing device, automatically packages workpieces to a rated weight, improving the accuracy and consistency of the packaging weight, effectively avoiding overweight or underweight issues, and increasing production efficiency.
