Packaging equipment is a key product in the packaging machinery industry, it plays an important role in the packaging machinery industry, providing the industry with the technical equipment necessary to complete the product packaging process. This article mainly introduces the working principle and design process of the packaging machine - automatic granule packing machine, calculates the parameters of its transportation system and checks the strength of transportation components, and makes reasonable improvements to its overall appearance, box and rack. The automatic granule packing machine is mainly suitable for small size automatic packing for bulk non-stick micro granules for packing food, tea, medicine, chemicals and other products. Packaging material is a composite material, which is bonded at a high temperature. This machine mainly includes horizontal sealing mechanism, vertical sealing mechanism, feeding mechanism, shearing mechanism, transmission mechanism and electrical control system. In this design, our main task is to improve the arch of the transportation system and the whole machine cabinet to meet the design requirements to achieve the required production efficiency. The advantage of this machine is that it can automatically complete bag making, adjustable cup counting, filling, sealing part sealing, etc. The machine also adopts an inorganic mechanism to adjust the bag-making length and smart branding device.
