Design of Automatic Packaging Machine 1. Design Topic: Automatic Packaging Machine Automatic packaging machine is mainly used for automatic packaging of materials in industries such as food, medicine, chemical industry, and plant seeds. The material can be in the form of granules, tablets, liquids, powders, pastes, etc. The automatic packaging machine has functions such as automatic measurement, filling, bag making, sealing, cutting, conveying, printing batch number, adding easy cutting, no material warning, mixing, etc. Its main features include: 1) Components that come into contact with materials are made of stainless steel and non-toxic and corrosion-resistant plastics, meeting various packaging requirements. 2) Realize stepless adjustment of packaging speed and bag length. The packaging speed and bag length can be infinitely adjusted within the specified range, without the need to replace parts, making it simple and convenient. 3) Adopting photoelectric detection, stable and reliable. 4) According to different bag materials and predetermined temperatures, dual heat sealing can be used, and good thermal balance can ensure the quality and beauty of the sealing. 5) Easy to operate and convenient to maintain. 6) Simple structure, beautiful appearance, and moderate price. 7) Lightweight and easy to transport. 8) Excellent performance and long service life. 2. General operation method of automatic packaging machine: The power of automatic packaging machine generally adopts a three-phase four wire power supply. The entire mechanical system consists of a power system, a main transmission system (including a stepless speed regulation device), and an execution system (including a bag pulling mechanism, a bag forming mechanism, a heat sealing mechanism, and a paper feeding mechanism).
