Sometimes we will find that the powder packaging machine is not accurate, this time how to deal with it?
1. The relationship between the packaging accuracy of powder packaging machine and the spiral: powder packaging machine, especially the small dose of powder packaging machine, that is, the packaging specifications in the range of 5-5000 grams, the conventional feeding way is spiral feeding, and there is no measurement method of instant weighing. Screw feeding belongs to volumetric measurement, the consistency of the volume of each screw pitch of the screw is the basic condition to determine the measurement accuracy of powder packaging machine, of course, pitch, outer diameter, bottom diameter, spiral blade shape will affect the packaging accuracy and speed.
2. The relationship between the packaging accuracy of powder packaging machine and the outer diameter of the screw: the packaging accuracy of powder packaging machine and the outer diameter of the screw should be said to have a very direct relationship, and the premise of the screw pitch is to determine the size of the outer diameter of the screw, to do the comparison. Generally speaking, powder packaging machine in the selection of metering screw is generally determined according to the size of packaging specifications, but also consider the proportion of materials to adjust appropriately.
3. The relationship between the packaging accuracy and screw pitch of powder packaging machine: how about the packaging accuracy and screw pitch of powder packaging machine? Here we can illustrate with examples. For example, when packaging 50 grams of cumin powder, our packaging machine uses φ30mm outer diameter spiral. The pitch we choose is 22mm, and the accuracy of ±0.5 grams is more than 80%, and the ratio of ±1 grams is more than 98%. However, we have seen the spiral with φ30mm outer diameter and the pitch is more than 50mm in the same industry. What's going to happen? The feeding speed is very fast, and the measurement accuracy is about ±3 grams.
