Common faults of liquid filling machines and how to solve them

Release Date:2023-04-28 10:56:00 Popularity:

  Filling machines are mainly a small category of products in packaging machines. From the perspective of packaging materials, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and particle filling machines; from the degree of automation of production It is divided into semi-automatic filling machine and fully automatic filling production line. Recently, with the QS certification of food, food processing manufacturers have begun to pay attention to product quality and packaging, so more and more manufacturers use various filling machines, and liquid filling machines are used more often in the food industry. installed.

Common faults of liquid filling machines and how to solve them

  1. The accuracy error in the filling process is large

  The filling error is mainly determined by the filling volume, filling speed, and the switching speed of the upper and lower valves. The switching speed of the upper and lower valves is related to the viscosity of the product, the greater the viscosity, the slower the valve switching speed.

  The spring pressure of the adjustment valve of the liquid filling machine should be determined by the test filling measurement and the experience of the operator.

  Adjusting the opening and closing speed of the valve is mainly to adjust the spring pressure of the valve. As the spring pressure increases, the opening and closing speed of the valve will increase.

  2. The liquid filling machine does not respond when it is started and cannot work normally

  Turn off the power first, check whether it is a wiring problem, and check the fuse.

  Release the emergency stop button, and then start the machine again.

  Check whether the switching power supply has power.

  Check whether the connection between the mechanical touch screen and the PLC communication line is intact.

  3. When the material of the liquid filling machine does not go down and cannot be filled.

  Check whether the nozzle is closed and restart the machine.

  Check whether the air pressure is normal and whether the injection cylinder and cylinder are leaking.

  The material reaches the minimum limit, which is not enough to fill the corresponding container.
