I. relationship between packaging accuracy of powder packaging machine and screw
powder packaging machine, especially low-dose powder packaging machine, that is, when the packaging specification is within the range of 5-5000 grams, the most conventional feeding method is screw blanking, and there is still no measurement method of immediate weighing. Spiral blanking is a volumetric metering method. The consistency of the volume of each pitch of the spiral is the basic condition to determine the metering accuracy of the powder packaging machine. Of course, pitch, outer diameter, bottom diameter and spiral blade shape will affect the packaging accuracy and speed
Second, the relationship between the packaging accuracy of powder packaging machine and screw pitch
is there a relationship between the packaging accuracy of powder packaging machine and screw pitch? It can be said for sure: Yes
as we said earlier, the packaging accuracy and speed of powder packaging machine are related to the pitch, bottom diameter and outer diameter of the screw, and the shape of the machine screw
How about the packing accuracy and screw pitch of the powder packing machine? We can give examples. For example, our seasoning packaging machine is selected when packaging 50g cumin powder φ For the screw with outer diameter of 30mm, the pitch we choose is 22mm, the proportion of accuracy ± 0.5g is more than 80%, and the proportion of accuracy ± 1g is more than 98%. However, we have seen peers at customers φ What happens to a screw with an outer diameter of 30mm and a pitch of more than 50mm? The blanking speed is very fast, and the measurement accuracy is about ± 3 g. The industry standard QB /T 2501-2000 (there is no national standard for this item) requires that the packaging specification of class X (1) weighing instrument is ≤ 50g, and the maximum allowable deviation is 6.3%, which also meets the standard of X (1). However, for customers, the packaging accuracy is directly related to the product cost, which is better or worse, which is clear at a glance
III. The relationship between the packaging accuracy of the powder packaging machine and the spiral outer diameter
the packaging accuracy of the powder packaging machine should be said to have a very direct relationship with the spiral outer diameter. As mentioned earlier, “the relationship between the packaging accuracy of the powder packaging machine and the spiral pitch”. The premise of the relationship with the pitch is that the spiral outer diameter has been determined before comparison. Generally speaking, when selecting the metering screw for the powder packaging machine, it is generally determined according to the packaging specification, and the specific weight of materials will also be considered for appropriate adjustment. For example, when packing 100g pepper powder in our low-dose packaging machine, we generally choose the spiral with a diameter of 38mm, but if the packaging is glucose with high bulk density, it is also 100g, we need to use the spiral with a diameter of 32mm
that is to say, the larger the package specification, the larger the outer diameter of the selected spiral, so as to ensure both the packaging speed and the measurement accuracy

the powder packaging machine may be adjusted incorrectly by you, or your materials may not be very powdered
