We must master the daily use skills of packaging scales

Many companies now use some automatic packaging equipment, and packaging scales are one of them. However, we must master the daily use skills of packaging scales to avoid large errors. For example, when the feeding amount of the packaging machine is very unstable, the high speed value should be gradually increased until the small material door has a separate feeding time of about 2-3 seconds; when the small material door alone feeding time often exceeds 3 seconds, The high speed value should be gradually reduced until the small gate has a separate feed time of around 2-3 seconds.

Under normal circumstances, the large material door and the small material door of the packaging scale are opened together at the beginning of feeding, and the large material door is closed when the high speed value is reached; the small material door continues to feed for 2-3 seconds, and the small material door is closed when the fast value is reached; The vibrating feeder continues to feed for 0.5-3 seconds. When the drop is reached, the vibrating feeder is closed and the feeding is completed.

If you need to replace the packaging materials, you should manually open and close the large material door and small material door of the packaging scale several times after the last bag of the current product is finished. The residual material remaining in the feeder cannot be cleaned by opening the vibrating feeder for a long time, so as not to damage the vibrating feeder.

In addition, be careful not to change the parameters such as the set value, high speed value, fast value and drop during the feeding process of the packaging scale. You should change the above parameters when the packaging is not started or the feeding is completed but the scale is not discharging, otherwise it will affect the package. weight; and it is also necessary to manually check whether the action of the large gate, the small gate and the vibrating feeder is normal before use.

If the packaging scale is packing powder materials, the gas breaker must be turned on. The pressure of the gas breaker pipeline should be adjusted to 0.08-0.12MPa; the total pressure gauge should be guaranteed to be 0.4-0.6MPa; The potentiometer on the controller should be adjusted in the 1/2-2/3 position.

With the advancement of technology, electronic weighing technology has become an important technology in modern weighing measurement and control system engineering, and electronic quantitative packaging scales are the specific application of this technology in quantitative systems. Different from ordinary packaging scales, electronic quantitative packaging scales can achieve dynamic quantitative weighing with high weighing accuracy and high weighing speed, which is of great significance.

The reason why the electronic quantitative packaging scale can do this is inseparable from its technological process and functional characteristics. The operation process of the electronic quantitative packaging scale is divided into two parts: automatic and manual. The automatic part refers to its feeding, weighing Heavy, while the manual part is responsible for bag clamping, unloading and feeding.

The feeding device of the electronic quantitative packaging scale is a large and small two-stage feeding method. When the material weight reaches the set value of the medium feeding, the fast feeding will be stopped, and the small and accurate feeding will be maintained; when the material weight reaches the set drop value , close the feeding door to complete the dynamic weighing process.
