The automatic packaging production line is a kind of electrical and automatic control system with advanced technology, high reliability, economic and practical, production, transportation, packaging, cleaning system, etc., which is customized for the enterprise by using DCS, PLC and other control systems
Indicator light: generally, most of them are light-emitting diodes, with long service life, neon bubble and bulb, etc., with short service life, AC and DC working voltage.
Button and emergency stop switch: buttons are usually used for pneumatic, temporary and other control keys, and some rotary buttons are used for control; emergency stop buttons are generally red and yellow.
Fuse: mainly protection circuit, when the voltage and current is too large, it can fuse the protection circuit.
Transfer switch and power switch: control key.
Circuit breaker: it is mainly used to restore short-circuit protection. When the circuit and electrical device have instantaneous short circuit and instantaneous high current, it will trip automatically and protect the back circuit.
AC contactor: mainly used to control the main circuit of the equipment on and off, the general current is larger. Use contact to control the power supply.
Intermediate relay: the same as the AC contactor is used to protect the circuit.
Thermal relay: it is a thermal element, which is mainly used for the protection of over high temperature and automatic short circuit protection of the circuit behind.
Time delay protector: generally divided into power on delay and power off delay.
Knife switch: it is mainly controlled and controlled by manual breaking. It can be divided into 2 knives and 3 knives.
Leakage switch: mainly used to protect personal safety, there are single-phase and three-phase leakage switch.
The purchase of each part must be selected for strict screening. Only by ensuring the stability of the parts function can the normal operation of the automatic packaging production line equipment be ensured.
