With the continuous progress of science and technology, automation has become an inevitable trend in all walks of life. In this process, the automatic packaging machine for plastic granules has come into being, bringing great convenience to the plastic products industry. This paper will elaborate on the role of plastic granule automatic packaging machine, principle, application prospects and other aspects, revealing its important application value and development trend.

　　First, the background and significance of the plastic granule automatic packaging machine

　　Plastic granule automatic packaging machine is a kind of equipment specially used for packaging plastic granules, and its appearance greatly improves the production efficiency and product quality of the plastic products industry. In the traditional manual packing method, there are problems such as slow packing speed, irregular packing and high labour cost. The plastic granule automatic packaging machine can effectively solve these problems, to achieve high efficiency, precision, automatic packaging.

　　Second, the role and principle of plastic granule automatic packaging machine

　　Role: the main role of automatic packaging machine for plastic granules is to automatically complete the measurement of plastic granules, bagging, sealing and other processes to improve production efficiency and reduce labour costs. At the same time, the automatic packaging machine can also effectively avoid packaging quality problems caused by human factors, to ensure that the quantity and quality of plastic granules in each bag meet the standard.

　　Principle: The working principle of plastic granule automatic packaging machine is mainly through the hopper, measuring device, bagging device and sealing device and other components to complete. Firstly, the plastic pellets enter the hopper and the sensor in the hopper detects the quantity of plastic pellets. Then, the metering device transmits the detected quantity of plastic granules to the bagging device. After receiving the signal, the bagging device opens the corresponding bag and loads the plastic granules into the bag. Finally, the sealing device will seal the bag to complete the whole packaging process.

　　Third, the application prospects of automatic packaging machine for plastic granules

　　With the continuous improvement of environmental awareness, people's demand for plastic products is also gradually reduced. However, in some areas, plastic products are still indispensable. For example, in agriculture, industry, construction and other fields, plastic products are still used in large quantities. Therefore, the market demand for plastic pellet automatic packaging machine is still high.

　　In addition, with the increasing demand for personalisation, the variety of plastic products has become richer and richer. This not only brings a broader application space for plastic pellet automatic packaging machine, but also puts forward higher requirements for its performance and precision. In the future, the plastic granule automatic packaging machine will continue to develop in the direction of high precision, high efficiency and intelligence.

　　To sum up, the plastic granule automatic packaging machine has obvious advantages in improving production efficiency, ensuring product quality, reducing labour costs, etc., and its application prospects are very broad. In the future, with the progress of science and technology and the continuous change of market demand, the automatic packaging machine for plastic granules will continue to develop and improve, bringing more convenience and development opportunities for the plastic products industry. Therefore, we have reason to believe that the plastic pellet automatic packaging machine will play a more important role in the future development.
