At present, there are mainly two types of multi-head weighing equipment at home and abroad: the first type is a multi-head computer combination weigher; the second type is a multi-unit weigher. Although the latter also has multiple weighing heads that can weigh different loads separately, and each weighing hopper discharges materials to the same loading device separately, this type of scale does not have a combination function. The user must distinguish it when choosing a multi-head scale, otherwise it will be very difficult. It is difficult to meet the requirements for use. What kind of product is suitable for multi-head computer combination weigher? Multi-head weigher is mainly used for high-speed, high-precision automatic quantitative weighing of uniform and uneven particles, regular and irregular bulk items. There are mainly the following categories of products: the first category is puffed food; the second category is candy and melon seeds; the third category is pistachios and other large-shell nuts; the fourth category is jelly and frozen food; the fifth category is It is snack food, pet food, plastic hardware, etc. What aspects should users pay attention to when choosing a multi-head computerized combination weigher? 1. Accuracy requirements When choosing a multi-head scale, users are generally willing to choose a high-precision multi-head scale in order to reduce the loss caused by multiple products. Therefore, users should understand the important allowable error requirements of the packaged food before purchasing a multi-head scale.
2. Requirements for measuring speed When users choose a multi-head weigher, in order to obtain good economic benefits, it is also very important to choose high-precision equipment while being fast. At present, the weighing speed of domestic ordinary multi-head scales is about 60 bags/min, but the more weighing heads, the faster the speed. For example, the speed of 10-head scale is 65 bags/minute, and the speed of 14-head scale is 120 bags/minute. At the same time, the user should also pay attention to the lifting conveyor and packaging machine at the front and rear ends of the multihead weighing scale with comparable speeds to complete the whole process from weighing to packaging. 3. Requirements for material specific gravity and particle size For materials with different specific gravity, when choosing a multihead scale, because the specific gravity of the material is different, even the same weight of material will have a large difference in volume. Therefore, the user cannot choose a multihead scale. See the maximum combined weight of the scale and also refer to the maximum combined capacity.
