The multihead combination weigher, also known as combination weighing apparatus, is used for rapid quantitative weighing of granular, strip and irregular materials, which is composed of multiple independent weighing units with feeding and discharging structures. First of all, the AD weighing module converts the elastic deformation of the pressure sensor weighing unit into a weight value and stores it in the register, then the CPU reuses the principle of permutation and combination to automatically optimal combination calculate the weight value of the weighing unit, and obtain the best weight combination which is the closest to the target weight value for blanking.

When it comes to packaging products, the "automatic loading weighing apparatus" is indispensable, which separates various bulk solid materials into independent loads according to the set values. The traditional "automatic loading weighing apparatus" has only one weighing hopper, however, with the increase of packaging varieties, the acceleration of packaging speed and the improvement of packaging accuracy, the single hopper weighing can no longer meet the needs of the market. Therefore, at the end of the twentieth century, a diversified and intelligent "automatic loading weighing apparatus" appeared. R61 is suggested to call it a "multihead weigher " by international recommendations. This type of weighing apparatus uses multiple hoppers (8 to 32 hoppers) to weigh at the same time, and then uses a computer to determine which combination of weighing hoppers is close to the set value.

The combination weigher is mainly composed of a feeder hopper, a material photoelectric detection switch, a main vibration plate (main vibration machine), a line vibration plate (linear vibration machine), a storage hopper, a weighing hopper, a drive device (stepping motor), a discharge chute, collecting hopper, motor drive board, main board and A/D module. Here is a detailed introduction to the working principle of the combination weighers.

Combination weighers are widely used in the quantitative packaging of granular food, potato chips, candy, puffed food, biscuits, frozen vegetable food and other industries due to their high-speed, high-precision weighing, high degree of automation and other performances. The combination weighers solve the problem of the large measurement errors caused by the small weight of a single piece, which reflect the revolution and superiority of the combination weigher in the field of weighing apparatus.

It can be said that food packaging can be seen everywhere in daily life, most of the commodities in the supermarket are packaged, also, packaging can ensure that the food inside is clean, prevent the food from moisture and mold as well as can extend the shelf life of the food. Now factories are all using the automated packaging equipment to package, so what are the advantages of using automated packaging equipment compared with the manual labor?

With the development of the food industry, the requirements for food packaging are getting higher and higher, and some traditional packaging equipment can no longer meet the needs. Therefore,some high-precision packaging equipment appeared, such as automated packaging equipment.
