Working principle of vacuum packaging machine

With the improvement of the degree of automation, the operation, maintenance and daily maintenance of the packaging machine are more convenient and simple, and the professional skills requirements of the operators are reduced. The quality of product packaging is directly related to the temperature system, the speed accuracy of the host, and the stability of the tracking system.

The tracking system is the control core of the packaging machine. It adopts forward and reverse bidirectional tracking, which further improves the tracking accuracy. After the machine is running, the film marking sensor continuously detects the film marking (color mark), and at the same time, the tracking microswitch of the mechanical part detects the position of the machine. The above two signals are sent to the PLC. After the program operation, the output Y6 ( Positive and negative tracking) and Y12 (reverse tracking) control the positive and negative tracking of the tracking motor, find out the errors in the production process of packaging materials in time and accurately compensate and correct them, avoiding the waste of packaging materials. If the inspection still fails to meet the technical requirements after tracking the predetermined number of 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 drive is greatly reduced, the stability and reliability of the machine operation are improved, and the The noise of the machine running. It guarantees the high-tech level of the packaging machine with high efficiency, low loss, automatic detection and other multi-functional and fully automatic functions.

Although the application function of the transmission system used in the automatic packaging machine is relatively simple, it has high requirements for the dynamic performance of the transmission, and the system requires fast dynamic follow-up performance and high speed stability accuracy. Therefore, the dynamic technical indicators of the inverter must be considered, and high-performance inverters can be selected to meet the requirements.
