What is the principle of the automatic weighing and packaging machine? The automatic packaging machine can also save labor costs. Therefore, choosing equipment with good performance will be more economical and practical. The service life of one device can last for more than ten years, with a low failure rate, which will save a lot of labor costs. Moreover, the packaging of products is also good. Overall, it will be more suitable. Just like the domestic packaging machines have a long service life and a low failure rate. Maintenance is also very convenient. There are already many application examples in China.
It is mainly composed of self-unloading weighing, lifting, silo, electrical control and other parts. It has excellent performance and is made up of material layer gates, conveyor belts, switch gates, etc. A dual-speed motor is used to control the conveying speed of the conveyor belt and the height of the discharge layer, as well as the feeding amount, to achieve the purpose of accurate measurement.
The self-unloading scale is mainly connected to the weighing sensor with connecting bearings or pins, so that the weight and load of the scale bucket can be accurately displayed on the scale. The unloading door at the bottom of the hopper of the automatic weighing and packaging machine is generally pushed by a cylinder, and the relative balance of the weighing hopper can be maintained throughout the working process.
As a key component of the fully automatic weighing machine, the electrical control equipment not only has functions such as coarse, fine, over-adjustment compensation, and unloading control, but also has a high conversion rate when the load exceeds the allowable range, playing a role in self-protection upon power-off
During the weighing process, the electronic control device of the automatic weighing machine controls the number of feeding packaging boxes based on the load changes of the sensor when the predetermined packaging volume is reached. The feeding machine stops feeding and sends out a discharge signal. Our actual operation is very simple, and the packaging speed and accuracy can easily meet the requirements. It is a kind of automatic packaging machine suitable for large quantities.
