How to choose a cost effective multihead combination scale

  • 2022-06-24
With the acceleration of my country's economic globalization process, quantitative packaging commodities have sprung up in commodity retail markets across the country. Considering the accuracy and safety of food measurement, in order to make packaged food meet the requirements of the above regulations, all retail commodity manufacturers in the country have equipped packaging measurement and testing equipment. Among them, our high quality multihead combination scales are especially favored by enterprises.

At present, there are two types of multihead scale equipment at home and abroad: one is a multihead intelligent combination scale (hereinafter referred to as a multihead scale); the other is a multi-connected scale. Although the latter can weigh different loads separately by multiple weighing heads, and each weighing hopper discharges materials to the same charging device, but this type of scale does not have a combination function, users must distinguish when choosing a multihead scale, otherwise it will be very difficult. Difficult to meet usage requirements. What kind of products are suitable for multihead intelligent combination scales, multihead scales are mainly used for high-speed, high-precision automatic quantitative weighing of uniform and uneven particles, regular and irregular bulk items, and the first type is large in size and light in weight. The second category is the items that are easy to stick and have poor flow; the third category is the food that is difficult to separate; the fourth category is the fragile packaged food; the fifth category is the frozen packaged food; the sixth category is the leaky packaged food; The seventh category is dry and fresh fruit and local product packaging.

Users should pay attention to the following aspects when choosing cost effective mix multihead weighers:
1. Accuracy requirements. When choosing a multihead scale, in order to reduce the loss caused by multi-packed products, users are generally willing to choose a high-precision multihead scale. Therefore, users should understand the important allowable error requirements of packaged food before purchasing a multihead scale.

2. Metering speed requirements. When users choose a multihead scale, in order to obtain good economic benefits, it is also very important to choose high-precision equipment at the same time as fast speed. At present, the weighing speed of ordinary multihead scales in China is about 70 bags/min, but the more weighing heads, the faster the speed. For example, the speed of 10-head scales and 14-head scales is 65-140 bags/min. The speed of the scale is 190-240 bags/min. At the same time, users should also pay attention to matching lifting conveyors and packaging machines with comparable speeds at the front and rear ends of the multihead scale to complete the whole process from weighing and measuring 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, the volume will be very different, so users can not only look at the multihead scale when choosing a multihead scale. The maximum combined weight of the scale should also refer to the maximum combined capacity. For example, a multihead scale with a maximum combined weight of 1000 grams generally has two specifications with a maximum combined capacity of 2000ml and 5000mi. For materials with different particle sizes, when choosing a multihead scale, users should first look at the particle size of the object to be weighed. Generally, bulk materials are divided into block (>lomm), granular (>0.5-lomm), powder (≤0 .5mm) in three cases. Among them, for powdery materials, users need to choose the central column, feeding vibrator, transition bucket and weighing bucket in the feeding process, which are leakproof weighing waterproof scale.

Finally, it should be emphasized that users must consider the reliability of the equipment and the maintenance and interchangeability of components when choosing a multihead scale, and do not think that it is enough to meet the functional requirements. Generally speaking, multihead scales are equipment that cannot be stopped in the middle of the production line. If the equipment is cheap and usable, and its reliability and interchangeability are not considered, it is likely to cause many problems for users in the production process.
