Quantitative packaging machine is a packaging machine that includes four major components: automatic weighing device, conveying device, sewing device, and computer control system. However, when it is used, its quantitative device will fail, so what is the cause of the phenomenon?

In the process of checking the working status of the quantitative packaging machine, it was found that the process of the material entering the quantitative packaging machine container from the quantitative cup is not smooth, which may be blocked by the channel, poor exhaust, and the filling mouth and the packaging container mouth are not aligned properly, etc., should be checked Blocking reasons and adjust the packaging positioning device. It is possible that the quantitative measuring cup of the quantitative packaging machine is not full. The capacity of the measuring cup is adjusted incorrectly; the feeding of the hopper is too slow or unstable; the loading surface of the hopper is too low; the feeding tube is too small and the material flow is not smooth; the feeding tube and the measuring cup waiting differently. It is also possible that the running speed of the material re-circulating charging machine is too fast, and the speed of the material being dropped from the hopper is too fast.


In addition to the above factors, the adjustment of the expansion mechanism of the excessive return flow cup is improper; the overflow of the material container is not concentric with the feeding tube, the beat is not accurate, the container is too small or the material in the feeding tube causes the feeding to lag; the spiral speed is very low or the speed is Unstable materials are too private, or the screw rotation setting is too large and the materials are crowded, resulting in abnormal rotation, etc., which will also cause the channel of the quantitative packaging machine to be blocked. In other words, its clutch is not working properly or the belt is loose. You should refer to the clutch instruction manual to check and adjust the clutch or tighten the belt. If the counter does not count, the encoder connection may be faulty or the coupling on the encoder is loose or the coupling is broken.
