Precautions for the selection of multi-head combination weigher
With the acceleration of the globalization of the economy, quantitatively packaged goods are rapidly emerging in retail markets around the world, especially in the food industry. In order to make packaged foods meet the requirements of industry regulations, packaging measurement and testing equipment has been installed one after another. The multi-head combination weigher is especially popular among enterprises.
At present, there are two types of multi-head weighing equipment at home and abroad: one is a multi-head combination weigher; the other is a multi-unit scale. Although the latter can weigh different loads by multiple weighing heads, 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 between them when choosing a multi-head scale, otherwise it will be very difficult. It is difficult to meet the requirements for use. Multi-head combination weigher is mainly used for high-speed and high-precision automatic quantitative weighing of uniform and uneven particles, regular and irregular bulk items. The first category is bulky and light weight items, and the second category is easy to adhere. Poor flow items; the third category is foods that are difficult to separate; the fourth category is fragile packaging foods; the fifth category is frozen packaged foods; the sixth category is leaky packaged foods; the seventh category is dried and fresh fruits and native products .
What aspects should be paid attention to when choosing a multi-head combination weigher
1. Accuracy requirements
In order to reduce the loss caused by multiple products when choosing a multi-head scale, the user is generally willing to choose a high-precision multi-head scale. Therefore, the user should understand the important allowable error requirements of the packaged food before purchasing the multi-head scale.
2. Requirement of metering speed
When users choose a multihead weigher, in order to obtain good economic benefits, while choosing high-precision equipment, fast speed is also very important. At the same time, the user should also pay attention to the matching speed of the lifting conveyor and the packaging machine at the front and rear ends of the multihead scale to complete the whole process from weighing and measuring to packaging.
3. Material specific gravity and particle size requirements
For materials with different specific gravities, when selecting a multi-head scale, because the specific gravity of the material is different, even the same weight of materials will have a large difference in volume. Therefore, the user cannot just look at the maximum combined weight of the scale when choosing a multi-head scale. Also refer to the maximum combined capacity. For example, a multihead weigher 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, users must first look at the particle size of the object to be weighed when choosing a multihead scale. Generally, bulk materials are divided into block (>lomm), granular (>0.5-lomm), and powder (≤0). ．5mm) Three situations. Among them, for powdery materials, the user should choose the center column, feeding vibrator, transition hopper and metering hopper in the feeding process to be sealed, leak-proof, and waterproof multi-head weighers.
The last thing to be emphasized is that users must consider the reliability of the equipment and the interchangeability of parts when choosing a multihead scale. Don't think that it is enough to meet the functional requirements. Generally speaking, a multi-head weigher is a device that cannot be stopped in the middle of the production line. If you blindly pursue cheap and usable equipment without considering its reliability and interchangeability, it is likely to cause many problems for users in the production process.
