How to deal with the zero point fluctuation of the packaging scale?

When purchasing a packaging scale, pay attention to the measurement accuracy of the packaging scale. The packaging speed is also an indicator of He Liang's product quality. The packaging speed and accuracy of the packaging equipment are inversely proportional, that is, the faster the speed, the lower the relative accuracy, and vice versa, the higher the accuracy. When selecting a semi-automatic scale, if the speed exceeds 1200 bags/hour, manual bagging will not be able to keep up, so the packaging speed is too fast and has no practical significance. Fully automatic equipment, after ensuring accuracy, the faster the better.

The operation interface of the control system is difficult and easy. When purchasing equipment, it is necessary not only to choose equipment with suitable functions, but also to choose equipment with a simple and easy-to-understand operation interface, which is convenient for workers to operate and maintain. Mainly the operation of the computer controller panel. Product performance advancement, stability and reliability. The stability of product performance depends on whether the equipment itself is advanced in technology and whether the main internal components are reliable, because they directly affect important performance indicators such as product service life, measurement accuracy, and packaging speed.

Due to the good performance of the quantitative packaging scale, it can provide great convenience for industry and agriculture, and more and more consumers are favoring it. So do you know what principles you need to follow when buying a quantitative packaging scale? First of all, you need to check the qualification of the manufacturer, including the manufacturer's reputation, production quality, integrity, etc. In addition, you also need to check whether the meter range of the quantitative packaging scale meets the specified standards.

During the operation of the packaging scale, the common failure problem is the zero point fluctuation of the packaging scale, that is, when there is no material on the packaging scale, the pressure is displayed on the weighing instrument, or the value on the instrument is constantly changing. When the zero-point fluctuation of the packaging scale occurs, we must not take it for granted, which will cause the equipment to produce errors in the subsequent measurement process.

Sometimes the error value is the same, most of the error values will be different, and with the extension of production time, the error value will become larger and larger. At present, the verification regulations for quantitative packaging of my country's Bureau of Technical Supervision stipulate that quantitative packaging does not allow negative differences, and the error value is within 50 grams. If there is a zero-point fluctuation failure, it must be repaired in time to avoid being investigated and dealt with by the Technical Supervision Bureau.

So how to deal with the zero-point fluctuation of the packaging scale? The first thing to do is to find out what caused the fault. In order to reduce costs, many quantitative packaging scale manufacturers use very cheap and simple weighing instruments. Most of these instruments are three-no products, and the quality is difficult to guarantee. After a period of use, there will be unstable phenomena. In this case, only The instrument can be replaced or the weighing speed and accuracy can be reduced to reduce the phenomenon of zero drift.
