The packaging machine
is also called a weighing and bagging machine. It is a kind of packaging equipment with automatic feeding, automatic weighing and out-of-tolerance alarm formed by the combination of a feeder and a computer scale. However, sometimes it may also have weighing failures. Exactly, why is this? Next, the editor of Jiawei Packaging will give you a simple analysis. Let's take a look. 1. The packaging scale of the packaging machine is not fixed when it is installed, so it is prone to overall shaking during work, and the vibration is very obvious, which makes the weighing structure inaccurate. 2. The feeding system of the packaging machine is unstable, with intermittent feeding or material arching, etc., which makes the equipment very prone to inaccuracy when weighing. 3. When the packaging machine is weighed, it is affected by external forces, such as the strength of the electric fan in the workshop and the instability of human operation. 4. The cylinder of the solenoid valve of the packaging machine is not flexible and accurate during normal operation, so inaccuracy is inevitable when weighing. 5. When the packaging machine is used for weighing, the discreteness of the packaging bag itself is not considered, and the weighing together with the packaging bag results in inaccurate weighing results.
