1. The working principle of food packaging machine
the pillow type automatic packaging machine is the leading and most reliable technology design and production in China, which brings together the essence of many years of experience in the packaging machinery field. The packer can use various composite packaging membrane to package the block food, which is very suitable for the needs of the vast number of users in China. 1) the electrical part of the automatic packaging machine is generally composed of the following:
A) the main control circuit is composed of man-machine interface (text display), frequency converter and programmable controller (PLC)
b) the temperature control circuit is composed of intelligent temperature control meter, solid-state relay, thermocouple elements, etc., with accurate temperature control, intuitive display and convenient setting
C) realize multi-point tracking and detection by photoelectric switch and electromagnetic proximity sensor; 2) Working principle of fully automatic pillow type:
with the improvement of automation, the operation, maintenance and daily maintenance of the packaging machine are more convenient and simple, reducing the professional skill requirements for operators. The quality of product packaging is directly related to the temperature system, the accuracy of host speed, the stability of tracking system and so on
the tracking system is the control core of the packaging machine. It adopts forward and reverse two-way tracking to further improve the tracking accuracy. After the machine is running, the film marking sensor constantly detects the film marking (color code), and the tracking microswitch of the mechanical part detects the position of the machine. The above two signals are sent to the PLC. After program calculation, the positive and negative tracking of the tracking motor is controlled by the output y6 (positive tracking) and Y12 (negative tracking) of the PLC, so as to timely find the errors of packaging materials in the production process and accurately compensate and correct them, The waste of packaging materials is avoided. If the test still fails to meet the technical requirements after tracking the predetermined times, it can automatically stop for inspection to avoid the generation of waste products
due to the use of frequency conversion speed regulation, the chain transmission is greatly reduced, the stability and reliability of machine operation are improved, and the noise of machine operation is reduced. It ensures the high-tech level of multifunctional and automatic packaging machine, such as high efficiency, low loss and automatic detection. Make it not only have a beautiful and fashionable appearance, but also have a healthy and smart mind
although the application function of the transmission system used in the food packaging machine is relatively simple, it has high requirements for the dynamic performance of the transmission. The system requires fast dynamic following performance and high speed stability accuracy. Therefore, the dynamic technical indicators of the frequency converter must be considered, and the selection of high-performance frequency converter can meet the requirements
