In modern industrial production, packaging automation has become an important means to improve production efficiency and ensure product quality. As one of the key equipments, granule automatic weighing packaging machine has been widely used in food, chemical, pharmaceutical and other industries. In this paper, we will discuss in detail the working principle, application areas, technical advantages and future development trend of automatic weighing packaging machine for granules.

　　First, the working principle of granule automatic weighing and packaging machine

　　Granule automatic weighing packaging machine is a set of weighing, measuring, packaging, sealing in one of the automated equipment, mainly for granular materials packaging. Its working principle can be summarized in the following steps:

　　1. Material feeding: the material is conveyed to the weighing hopper through the vibrating feeder or screw conveyor and other equipment. During the conveying process, the equipment automatically adjusts the feeding speed according to the set parameters to ensure the stability of the material flow.

　　2. Accurate weighing: When the material enters the weighing hopper, the equipment carries out real-time weighing by means of high-precision load cells. During the weighing process, the system will automatically make coarse and fine adjustments to the material to ensure that the final weighing result is accurate.

　　3. Automatic weighing: According to the pre-set packing specifications, the equipment will automatically convey the materials that have reached the set weight into the packing bags. The weighing system is automatically calibrated to ensure that the weight of each package is within the specified tolerance.

　　4. Automatic Packing and Sealing: When the weighing is completed, the material will fall into the packing bag automatically, and the equipment will then carry out automatic sealing. The sealing method can be chosen according to the material characteristics and packaging requirements, such as heat sealing, pressure sealing and other different ways.

　　5. Finished product output: the sealed bags are sent out through the conveyor belt to enter the next step of production or storage. The whole process is automatically executed by PLC control system to ensure the continuity and stability of the packaging process.

　　Second, the application field of granule automatic weighing and packaging machine

　　Granule automatic weighing packaging machine is widely used in the following main fields because of its high efficiency and precise packaging ability:

　　1. Food industry: In the food industry, granule automatic weighing packaging machine is mainly used to pack granular food such as rice, nuts, candy, feed and so on. Its high-precision weighing and fast packing ability ensures the quality and hygiene standard of food in the packing process.

　　2. Chemical industry: chemical products usually have a certain fluidity and volatility, granule automatic weighing packaging machine can prevent the leakage and deterioration of materials through sealed packaging. Typical applications include the packaging of fertilizers, plastic granules, pigments and other chemical products.

　　3. Pharmaceutical industry: The pharmaceutical industry requires high packing accuracy and hygiene conditions, the granule automatic weighing packaging machine can accurately control the measurement of the medicine, to ensure that the dosage of each packet of medicine is accurate, in line with the strict standards of the pharmaceutical industry.

　　4. Agricultural industry: the packaging of seeds, fertilizers and other granular materials in the field of agriculture also requires efficient and accurate equipment. Granule automatic weighing packaging machine can flexibly adjust the packaging specifications according to the needs of different crops, to meet the diversified needs of agricultural production.

　　Third, the technical advantages of automatic weighing packaging machine for granules

　　Granule automatic weighing packaging machine can be widely used in many industries, mainly due to its following technical advantages:

　　1.
