The current pillow type automatic packaging machine is designed and produced with the most mature and reliable technology in China, which gathers the essence of many years of experience in the field of packaging machinery. This packaging machine can use various composite packaging film coiled materials to package blocky food, which is very suitable for the needs of users in China. 1) The electrical part of an automatic packaging machine generally consists of the following components:

a) The main control circuit consists of a human-machine interface (text display), a frequency converter, and a programmable logic controller (PLC) as the control core;

b) The temperature control circuit consists of intelligent temperature control meters, solid-state relays, thermocouple elements, etc., with precise temperature control, intuitive display, and convenient setting;

c) Multi point tracking and detection are achieved through photoelectric switches, electromagnetic proximity sensors, etc; 2) Fully automatic pillow working principle:

With the improvement of automation, the operation, maintenance, and daily upkeep of packaging machines have become more convenient and simple, reducing the professional skill requirements for operators. The quality of product packaging is closely related to the temperature system, accuracy of host speed, and stability of tracking system.

The 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.

Due to the use of variable frequency speed regulation, the chain transmission has been significantly reduced, the stability and reliability of machine operation have been improved, and the noise of machine operation has been reduced. This packaging machine ensures high efficiency, low loss, automatic detection, and other multifunctional, fully automated high-tech capabilities. Make it have both a beautiful and fashionable appearance, as well as a healthy and agile mind.

Although the transmission system used in the transformation of food packaging machines has relatively simple application functions, it has high requirements for the dynamic performance of the transmission. The system requires fast dynamic following performance and high stable speed accuracy. Therefore, it is necessary to consider the dynamic technical indicators of the frequency converter and select high-performance frequency converters to meet the requirements.
