Note the range of the rice packaging scale The range of the packaging control instrument is the minimum distance between the quantitative point and the maximum quantitative point. The scientific range is that the maximum range point is 10 times the minimum range. For example: a reasonable range should be 1 ~ 10Kg, 0.5 ~ 5Kg, 5 ~ 50Kg, etc., because the lighter the weight of a single package, the relative relative error rate is higher, like using a 100 kg scale to weigh 50 grams of material, error It will be too big.
Note that the metering accuracy of rice packaging scales Currently on the market, automatic weighing scales that meet national measurement regulations are mainly divided into X (0.5) class and X (0.2) class (ie, the error rate is 0.5%, 0.2%). The weighing accuracy of X (0.2) grade products is higher than that of X (0.5) grade products, but the packaging speed of X (0.2) grade products in the same kind of products must be lower than that of X (0.5) grade products, so if the user does not require a high measurement speed For high accuracy, X (0.2) grade products should be selected, and vice versa, please select X (0.5) grade products.
Packaging speed is also an indicator of He Liang's product quality Packaging speed and accuracy of packaging equipment are inversely proportional, that is, the faster the speed, the lower the relative accuracy, on the contrary, the higher the precision. When selecting a semi-automatic scale, if the speed exceeds 1200 bags/hour, the artificial bag will not be able to keep up, so the packaging speed is too fast and has no practical meaning! Fully automatic equipment, after ensuring accuracy, the faster the better!
The control system's operation interface is difficult. When selecting the equipment, not only the equipment with the proper function should be selected, but also the equipment with simple operation interface and easy to grasp should be selected to facilitate the worker's operation and daily maintenance. Mainly the operation of the computer controller panel.
Product performance advancement, stability, reliability Product performance stability depends on whether the technology of the equipment itself is advanced and whether the internal main components are reliable, because they directly affect the important performance indicators such as product service life, measurement accuracy, and packaging speed.
Manufacturer's after-sales service The manufacturer's after-sales service is also a very important reference indicator, mainly reflected in whether it has a complete installation, commissioning, training, maintenance and other service projects.
Other conditions In addition to the above factors, the product's appearance, high cost performance, the number of related accessories, product transportation safety, product delivery time, payment methods, etc. are all factors that cannot be ignored.
