What makes the filling machine not work?

Filling machines are mainly a small class of products in packaging machinery. From the perspective of packaging materials, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granular filling machines; It is divided into semi-automatic filling machines and automatic filling production lines.

Here is an introduction

 

1. The main fault of PLC is the contact adhesion of output point relay. The fault phenomenon is that the motor runs after the signal is started, However, the motor did not stop after the stop signal was sent. When the PLC is powered off, the motor stops.

 

2. Proximity switch fault, the fault reason is that the melting knife is falling. It does not match the packaged object. When the melting knife rises, the proximity switch loses the signal, When the knife guard plate contacts the package, the melting knife automatically returns upward.

 

3. Magnetic switch fault, the main performance of the fault is that the subsequent cylinder does not act, because the cylinder speed is too fast, resulting in the magnetic switch can not detect the signal, If the speed of the pushing drum is too fast, the pressing drum and the melting drum will not work after resetting the pushing drum.

 

4. Solenoid valve failure, the main performance of the solenoid valve failure is that the cylinder does not work or does not reset, because the solenoid valve of the cylinder can not change direction or blow air.
