1, powder packaging machine packaging precision and screw correlation: powder packaging machine, especially dose powder packaging machine, that is, the packaging specification model in the range of 5-5000 grams, the basic feeding method is the screw feeding, and there is no timely weighing measurement verification method. Spiral cutting material belongs to volumetric measurement verification method. The consistency of the capacity of each tooth pitch of the spiral is the basic standard to determine the measurement verification accuracy of powder packing machine. Natural tooth pitch, diameter, bottom diameter and spiral leaf appearance will cause harm to the packaging precision and speed.


2. The correlation between the packaging precision of powder packaging machine and the diameter of the screw: the packaging precision of powder packaging machine and the diameter of the screw should be said to have a very immediate correlation. The premise of having a sexual relationship with the tooth pitch is that the diameter of the screw has already been clear, so that it can be done relatively well. Generally speaking, the powder packaging machine in the selection of measurement verification spiral is generally clear according to the packaging specifications, model size, and will also take into account the proportion of raw materials to moderate adjustment. For example, your dose automatic packaging machine in bulk 100 grams of white pepper, generally choose a diameter of 38mm spiral, but if the packaging is a heap density of glucose water, the same is 100 grams, you need to use a diameter of 32mm spiral. In other words, the larger the packaging specifications and models are, the larger the diameter of the selected spiral is, so as to ensure both the packaging rate and the accuracy of measurement verification;


3. The correlation between the packaging precision of powder packaging machine and the spiral tooth spacing: how about the packaging precision of powder packaging machine and the spiral tooth spacing? Here we can illustrate by example. For example, when your condiment automatic packaging machine packs 50 grams of cumin powder, it uses a screw with a diameter of 30mm. The tooth spacing we choose is 22mm, the accuracy of ± 0.5g is above 80%, and the ratio of ± 1g is above 98%. However, we have seen an effective screw with a diameter of 30mm in the same industry in the customer's place, and the tooth spacing exceeds 50 mm. Why does this happen? The feeding speed is fast, and the measurement verification accuracy is about ±3 grams. The national standard "QB/T2501-2000" on the X (1) grade measurement verification electronic weighing device is the packaging specification model ≤50 grams, allowable error 6.3%, the same is to achieve the specification of X, but for customers, the packaging precision of the height of the immediate associated with the production cost, which is better and worse, clear.
