A brief description of the weighing range of the

Usually people call automated packaging machinery also known as packaging production lines. Due to the need for unmanned and fast packaging needs, it is impossible for a machine to achieve all packaging links even with three heads and six arms. Usually a product needs to go through the following steps from the product to the commodities that can be circulated. The packaging process includes filling, wrapping, sealing and other main processes, as well as related before and after processes, such as cleaning, stacking and disassembly. In addition, packaging also includes procedures such as measurement or stamping on the package. The use of mechanical packaging products can increase productivity, reduce labor intensity, meet the needs of large-scale production, and meet the requirements of cleanliness and hygiene. The working principle of the combination weigher of the manufacturer's pair is to vibrate the material from the upper trough through the main vibration plate, and the material reaches the line vibration plate of each head. When the first layer hopper (called storage hopper) is empty, according to the set vibration time, the material will be vibrated from the line vibration plate to the storage hopper. When the weighing hopper below the storage hopper is empty after discharging, the storage hopper is opened and the material is discharged into the weighing hopper, and the weighing hopper starts to weigh. Therefore, there are many things that can be weighed, but if the shape is larger, the weight is higher, there is no way to weigh it. However, like some commonly used items in our lives, we can still weigh them with a combination scale. For example, some fasteners, granular items, powder, etc. can be weighed. Combination scales can also be designed according to the needs of manufacturers' products. For example, those that need to be waterproof and need to be dried can be customized. The weighing range of the combination scale is larger than that of the quantitative automatic packaging scale. In general, the weighing range of the quantitative automatic packaging scale under the same accuracy is controlled within 4 times, and the weighing range of the combination scale in the small scale section can reach more than ten times . It can also be seen from a large number of test results that there is a difference in the weighing range between the two. For example, in the weighing range of more than ten grams to one kilogram, the combination scale can meet the requirements of the accuracy level of x (1) level, especially in the small weighing section. If you want to keep the accuracy level unchanged, the quantitative automatic packaging scale can only reduce the weighing range and form a multi-segment weighing, and only rely on the production of multiple series of products to meet certain requirements of the manufacturer. Most manufacturers rarely accept this phenomenon. This brings limitations to its practical application, and can not meet the requirements of different packaging specifications (10-1000g) in some production areas but requiring similar accuracy.
