Conventional packaging machinery mostly uses mechanical control, such as cam distribution shaft type, and later appeared control modes such as photoelectric control and pneumatic control. However, with the increasing improvement of food processing technology, the requirements for packaging parameters are increasing, and the original control system has been difficult to meet the needs of development. New technologies should be used to change the appearance of food packaging machinery. Today's food packaging machinery is a mechanical and electronic device integrating machine, electricity, gas, light and magnetism. When designing, it should focus on improving the automation degree of packaging machinery, combining the research and development of packaging machinery with computer to realize electromechanical integration. control.
The essence of mechatronics is to use the principle of process control from the system point of view to organically combine machinery, electronics and information, testing and other related technologies to achieve overall optimization.
Generally speaking, it introduces microcomputer technology into packaging machinery, applies mechatronics technology, develops intelligent packaging technology, combines into automatic packaging system for production according to product automatic packaging process requirements, detection and control of production process, diagnosis of faults and Elimination will achieve full automation, achieving high speed, high quality, low consumption and safe production. It can be used for precise metering of aquatic products, high-speed filling and automatic control of packaging process, etc., which will greatly simplify the packaging machinery structure and improve the quality of packaging products. For example, the most common plastic bag sealing machine, its sealing quality is related to packaging materials, heat sealing temperature and running speed. If the material (material, thickness) changes, the temperature and speed will change accordingly, but it is difficult to grasp the change. If using microcomputer control, the optimal parameters of sealing temperature and speed of various packaging materials are matched into the microcomputer memory, and then equipped with necessary sensors to form an automatic tracking system, so that no matter which process parameters are changed, the best is guaranteed. Sealing quality.
