There are two main types of vertical packaging machines, one is the measuring cup packaging machine and the other is the multi-head scale packaging machine. The following mainly introduces the advantages, composition and application of these two packaging equipment.
Core Difference Overview
Measuring Cup Packaging Machine: Measuring based on volume. The material is taken by a cup (measuring cup) with a fixed volume and filled into the packaging bag. The accuracy mainly depends on the consistency of the material density and the uniformity of the filling.
Multi-head scale packaging machine: Measuring based on weight. Using multiple independent weighing buckets (usually 10-14), each bucket is weighed independently, and then the computer quickly combines and calculates to find the combination of several buckets closest to the target weight for unloading and filling. Accuracy is guaranteed by high-precision weighing sensors and intelligent algorithms.
