The components of an automatic packaging machine consist of the following parts: 1. The main control circuit consists of a human-machine interface (text display), a frequency converter, and a programmable logic controller (PLC) forming the control core; 2. The temperature control circuit consists of intelligent temperature control meters, solid-state relays, thermocouple components, etc., with precise temperature control, intuitive display, and convenient setting; 3. Realize multi-point clock tracking and detection through photoelectric switches, electromagnetic proximity sensors, etc;

The automatic packaging machine tracking system is the control core of the packaging machine, which adopts forward and reverse bidirectional tracking to further improve tracking accuracy. After the machine runs, the film marking sensor continuously detects the film marking (color code), while the mechanical part's tracking micro switch detects the position of the machine. The above two signals are sent to the PLC, and after program calculation, the PLC's outputs Y6 (forward tracking) and Y12 (reverse tracking) control the forward and backward tracking of the tracking motor, timely detecting and accurately compensating and correcting errors that occur in the production process of packaging materials, avoiding waste of packaging materials. If the detection still cannot meet the technical requirements after tracking the predetermined number of times, it can be automatically stopped for inspection to avoid the generation of waste products.
