Multihead Weigher component - Roughing hopper

As a high-precision mechanical equipment, each component of which plays a very important role, and the hopper plays a very key role in the Multihead Weigher.

Multihead weighing hopper workflow is divided into three steps. When feeding, the material passes through the main vibration disc and line vibration disc, and is vibrated into the storage hopper when it is empty. Weighing stage, after the weighing hopper is empty, the stock hopper discharges material into it and starts weighing. In the combination and discharging stage, the CPU of the main board processes the weight data of each weighing hopper, selects the combination close to the target weight, and when it receives the permission from the Packaging machine for feeding, it opens the selected weighing hopper and lets the material enter the collecting hopper or packaging machine through the chute.

The previous content on the smooth hopper to start the narrative, then this rough hopper to start the description, also from the material flow, cleaning and maintenance and durability of the three major aspects to start, so that we can compare the advantages between the two hoppers.

Material fluidity

Rough hoppers in contrast to smooth hoppers, rough hoppers are tailored for less fluid materials. The particle shape of some materials is irregular, easy to caking or with viscosity, etc., which is easy to have the problem of poor feeding or even blockage in the smooth hopper, and the rough hopper can solve this problem well. For example, crushed nuts rich in oil or sticky food powder can find a better passage in the rough hopper. By increasing the friction between the rough surface and the material, the material can be more stably attached to the hopper wall, avoiding the uneven cutting caused by too fast slidingThis friction gently ‘combs’ the material, breaking up lumps and ensuring that each weighing head receives a uniform and consistent amount of material, thus significantly improving weighing accuracy and product quality.

Cleaning and maintenance

Rough hopper cleaning work is relatively complex. Because the surface is covered with tiny concave and convex textures, these areas can easily be used for storing residues, especially for some food materials that are easy to deteriorate, if the cleaning is not thorough, it is very likely to breed bacteria, posing a serious threat to the quality of subsequent products.

Therefore, when cleaning the rough hopper, it is often necessary to use tools such as brushes to carefully scrub every corner to ensure that all dirt and residual materials are thoroughly removed. And after cleaning, more stringent inspections are needed to ensure that the hopper meets strict hygiene standards.

Degree of durability

Because of the uneven surface of the rough hopper, it will withstand relatively greater impact and friction when the material is frequently in and out. Especially for materials with higher hardness, such as grain particles with hard shells, it may cause more obvious wear on the surface of the hopper.

With the accumulation of time, this wear may change the roughness of the surface of the hopper, and then affect the effect of the material. However, by selecting materials with excellent wear resistance to make rough hopper, and implementing regular inspection and timely wear repair measures, such as the use of special coating technology or regular replacement of severely worn parts, it can also ensure that the rough hopper maintains good working performance within a certain service life.

In short, the choice of smooth or rough hopper needs to consider the material characteristics and production environment to ensure the efficient, accurate and stable operation of the Multihead Weigher Machine.
