The packaging machine can use a variety of composite packaging film coils to package bulk food, which is very suitable The needs of the vast number of users in China.
The electrical part of the automatic packaging machine generally consists of the following:
a) The main control circuit is composed of a frequency converter and a programmable controller (PLC) as the control core;
b) The temperature control circuit is composed of intelligent temperature control meters, solid state relays, thermocouple components, etc., with precise temperature control, intuitive display and convenient setting;
c) Multi-point tracking and detection are realized by photoelectric switches, electromagnetic proximity sensors, etc.;
According to the product status, there are liquid, block, and bulk packaging machines; according to the packaging function, there are inner packaging and outsourcing packaging machines; according to the packaging industry, there are packaging machines for food, daily chemical, textiles, etc.; according to packaging machines According to the degree of automation, there are semi-automatic and fully automatic packaging machines. There are many classification methods for packaging machinery. Each classification method has its own characteristics and scope of application, but all have their limitations. From the general situation of international packaging machinery, the more scientific classification method is to classify according to its main function, which can grasp the essence of things.
