How should we deal with the failure of quantitative packaging scales?

The packing scale is a measuring instrument, which belongs to the gravity type automatic loading weighing instrument. In order to ensure the correctness of its weighing, therefore, it is necessary to ensure the stability of the installation platform of the equipment when the equipment is installed. Only when the equipment is placed smoothly, the packaging scale will not affect the weighing accuracy due to the vibration of the machine during the working process. But in the actual use process, there will always be some problems. How should we deal with these?

In the normal production process, it is necessary to ensure that there is a certain amount of material in the buffer bin, and the packaging scale can be equipped with a low material level chain. After reaching the low material level, stop packaging and wait for incoming materials, otherwise it will affect the packaging accuracy. If it appears that each package is more or less than the set theoretical target value, and it is relatively stable and consistent. To solve this problem, you should increase or decrease the "advance amount", enter the "recipe" state, and increase or decrease the amount of advance value.

If every time the displayed value of the packaging scale instrument is very close to the set target amount, but the actual weight is more or less verified by the electronic platform scale. The appearance of this phenomenon indicates that the calibration of the weighing distance is not accurate. To calibrate the weighing distance in time, it is not necessary to re-calibrate in emergency treatment, just change the value of "target value" until the difference between the actual package weight and the theoretical value is within the approved error range.

There will also be a situation, that is, continuous weighing finds that the weighing value of the packaging scale instrument is unstable, and each package of materials fluctuates. In this case, we should first rule out whether there are external factors affecting the weighing, and solve the problem in a targeted manner according to the actual situation.

Automatic quantitative packaging scales are divided into buckets and buckets. Let's analyze the differences between them in detail:

1. Automatic quantitative packaging scale without bucket.

The weighing and quantitative control process of this packaging scale is relatively simple. The packaged items are directly put into the packaging bag for weighing, and the quantitative control process is achieved by controlling the size of the opening of the discharge port. It has the characteristics of simple structure and high precision.

2. There are bucket automatic quantitative packaging scales.

Bucket automatic quantitative packaging scale, also known as net weight scale, the control process of the packaging scale is to complete the quantitative feeding process through an intermediate weighing hopper. At the beginning, the feeding door of the weighing hopper is closed, and the upper feeding port is opened for constant value feeding. , when the target value is reached, close the feeding port, and open the feeding port to put the material into the package, and then enter the next control cycle.

In order to improve work efficiency, a variety of feeding speeds can be selected, generally two-speed, namely fast and slow. High-speed fixed-value control of double-scale rotation can also be used. The automatic quantitative packaging scale with bucket adopts an integrated structure, high precision and fast speed. This structure is mostly used by special weighing control equipment.

Due to the excellent performance of the packaging scale, the products are mainly used in the packaging of plastics, chemicals, grains, feed, food, metallurgy, mining, building materials, fertilizers, pharmaceuticals, rubber and other industries, as well as various bulk particles used in packaging lines, Powder packaging machinery.
