The weighpack machine is a kind of weighing and sorting equipment in the production line. The weightpack machine is based on the dynamic weighing technology, which realizes the functions of automatically transporting the products in motion to the weighing platform for weighing, and automatically sorting and rejecting them. Under the background that technology is the primary productive force, automatic weighpack machine with its advantages of full automation, high precision, 100% inspection rate, simple operation and maintenance and perfect function has become the best choice for food, pharmaceutical, chemical and battery industries to ensure quality, reduce cost and improve production efficiency. What are the functions of weighpack machine?

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.
