What should be paid attention to in the daily ues of combination scales
The multi-head microcomputer combination claims that the performance in both packaging accuracy and speed is greatly improved compared with the traditional metering method. At present, the industry generally sets the weighing error of multi-head scales as a positive deviation of 0.5-1.0g (weighing range 500g). At the same time, because the multi-head scale uses a computer for calculation, it effectively increases the combined speed (ie, weighing speed). A ten-head multi-head scale can weigh up to 70 times / minute. Fourteen-head multi-head scale, weighing speed up to 120 times / min. Many companies now have automatic packaging equipment, so what should be paid attention to in the daily use of combination scales?
When the feeding amount is very unstable (sometimes many, sometimes suitable), the high speed value should be gradually increased until the small feed door has a separate feeding time of about 2-3 seconds; when the small feed door is fed separately, the time is often When it exceeds 3 seconds, the high speed value should be gradually reduced until the small feed gate has a separate feeding time of about 2-3 seconds;
When the feeding amount is tens to hundreds of grams in most cases, the rapid value should be gradually increased until the vibration feeder has a separate feeding time of about 0.5-3 seconds; when the vibration feeder feeds separately When the time often exceeds 3 seconds, the rapid value should be gradually reduced until the vibration feeder has a separate feeding time of about 0.5-3 seconds;
When the feeding amount is tens of grams more in most cases, the drop should be gradually increased until the feeding amount is within the allowable error range; when the feeding amount is less than tens of grams in most cases, the drop should be gradually reduced until the feeding The amount is within the allowable error range.
For materials with different specific gravities, when the combination weigh is selected, because the specific gravity of the materials is different, the volume of even materials with the same weight will vary greatly. Therefore, the user cannot simply look at the combined weight of the scale when selecting the combination weigh. Refer to the combined capacity. The combination of Zhongshan Kenwei Automation Machinery Technology Co., Ltd. claims to adopt the intelligent triple stabilization mode, which makes the weighing more accurate. Each sensor has increased the number of stable multiple times of sampling and the internal comprehensive detection of the stable range. The value of is excluded, and the value can be more reasonable and accurate.
