Possible fault description of automatic quantitative packing scale

Automatic quantitative packaging scale has been on the market for a long time, and sales are very hot, not only that, it has taken the replacement of a lot of packaging scale, but the machine will always fail, we can not do so that the machinery will never break, what we need to do is to let our automatic quantitative packaging scale slow down the speed of bad, At this point we have to talk about the possible failure of our automatic quantitative packing scale:
(1) no bag, no material, usually bag switch, bag switch, control bag solenoid valve or cylinder problems.
(2) The size of the cutting door, weighing bucket feeding door can not be opened or closed, usually the problem of controlling the solenoid valve or cylinder.
(3) After the material is weighed, it is not possible to automatically open the feeding door and loosen the bag, or press the manual feeding button. Generally, there is a problem with the solenoid valve or cylinder of the control material door, which will return to normal after replacement of spare parts. If it is feasible to press the manual feeding button, it means that the weighing is out of tolerance or the system parameter setting is wrong.
(4) said bucket mouth or bag mouth leakage, usually is the scale body seal is not tight, insufficient pressure (check the air source is greater than 0.4MP) solenoid valve or cylinder problems.
(5) Inaccurate measurement, instrument display is unstable. It may be that instrument zero drift (calibration with standard weight) or parameter setting needs to be corrected (reset on the PV600 touch screen), or the weighing sensor is faulty (replace the sensor and take the weight nominal).
(6) When the system cannot discharge materials normally, set the selector switch to manual, and then press the discharge button for more than 3s, then the corresponding packaging scale can be restored to normal after the initial operation.
In this remind the general use of automatic quantitative packaging scale manufacturers, in the use of the machine, maintenance and care, the machine is beautiful, but also more durable, can also extend the service life of the machine and play the performance of the machine.
