Common faults and handling methods of juice filling machines

The fruit juice filling machine has brought great convenience to our enterprise’s production, and its efficient work is obvious to all. However, the PET bottle juice machine may inevitably encounter some large or small problems. Today, we will introduce common faults and solutions of fruit juice filling machines:

Fault problem:

If we are filling large specifications and the material tank is not replenished enough, the liquid level will be unstable. Causing inaccurate filling.

Solution:

You can increase the feeding amount or close the ball valve again, reset the filling time (extend the filling time), and slow down the filling speed to solve the problem.

Fault issue:

If the time does not change after adjusting the number dial or unit.

Solution:

At this point, turn off the power and reconnect it.

Fault problem:

If there is sufficient replenishment in the material tank, the liquid level is also stable, and the filling amount is inaccurate.

Solution:

There may be debris blocking the filling channel. Check the inlet of the material trough or the filling mouth, and clean up any debris.

Fault problem:

If there is a problem of dripping after closing and stopping liquid filling.

Solution:

1. The filling nozzle orifice may be damaged, and the filling nozzle can be removed to repair the orifice. The diameter of the orifice should not exceed 7.5mm. After repairing the aperture, gently grind the flat surface of the aperture on a water sanded paper.

2. The ball valve inside the filling head is damaged and needs to be replaced.

Fault problem:

If the injection switch is touched and the material is not filled, the digital indicator LED of the time relay will not flash.

Solution:

It is possible that the injection switch is damaged or the time relay base is loose. Replace the injection switch with the same model or tighten the time relay base.

Fault problem:

If the material is not filled after touching the injection switch, but the digital LED indicator light of the time relay flashes.

Solution:

1. Check if there is air pressure or if the pressure is too low. If it does not meet the air pressure requirements, we need to adjust it in a timely manner and start the machine for observation.

2. If the air pressure meets the requirements, it may be that the solenoid valve coil is damaged or the pneumatic valve core is stuck by dirt. You can unplug the power supply, open the board, use a tool to rotate or press the button next to the corresponding solenoid valve coil. If the valve can reverse, it indicates that the solenoid valve coil is damaged. If it cannot reverse, it indicates that the valve core is stuck. You can replace the solenoid valve coil or disassemble the valve for repair.
