The utility model discloses a packagine machine braking system, thus, power electric connection after the master switch passes through the wire and steps down through the transformer, packagine machine normally closed contact and delay relay coil and delay relay normally open contact parallelly connected each other are connected, just packagine machine normally closed contact passes through wire and brake coil electric connection. The utility model discloses this time quantum only need equipment can the barring can, this part energy consumption of standby can take corresponding means saving to get off, also is exactly the function that this system bring into play, more than the appearance the time quantum time, with complete machine outage, the system comes into operation with here, messenger's equipment can coil, satisfies the maintenance requirement, practices thrift standby energy consumption completely, the saving electric quantity.
