What should I do if I encounter the phenomenon that the packaging scale does not discharge the material and does not clamp the bag?

If you encounter the phenomenon that the packaging scale does not discharge the material and does not clamp the bag, you must first know whether the bag release switch and the bag clamping switch of the packaging scale are normal. If they are normal, you can also check the cylinder and solenoid valve of the packaging scale. If there is a problem with the two components, it will also reflect the appearance of no bag or no bag.

But what should I do if the feeding door of the packaging scale cannot be closed or opened? The problem may also lie in the cylinder and the control solenoid valve, so strengthening the inspection in this area will help solve the problem. It is about the measurement accuracy of the packaging scale, most of which are related to the parameter settings of the packaging scale.

From the past practical experience, among the many failures of quantitative packaging scales, the problems of speed and accuracy are significant. This obviously does not meet the basic requirements of packaging, so what are the requirements for the accuracy of quantitative packaging scale failure?

When packaging and weighing a product, there are not only requirements for the speed of packaging, but also strict regulations to ensure accuracy. In order to achieve this goal, it is necessary to set the value in the equipment and parameters, because the parameters determine the closing time of the big material gate, which is the speed of packaging.

For example, if the packaging scale is to achieve a weighing accuracy of class 0.2, the packaging scale must be able to weigh 11 bags per minute. Through debugging, the parameters in the instrument are adjusted to a good state, and the parameters determine the closing time of the small material door, so it must be set properly to ensure that the small material door can meet the weight requirements after it is closed once, otherwise it will cause excessive tolerance.
