Long scale engineering scientific name is also called 'combination weighing apparatus choice'.
It is composed of multiple independent feed discharging structure weighing units.
Computer by using the theory of permutation and combination will be automatic weighing unit load quantity optimization combination calculation, it is concluded that, close to the target weight value combination for the weight of the package.
Long microcomputer combined said is composed of multiple independent feed discharging structure weighing units, more than general microcomputer combination said consists of 8 ~ 32 weighing unit.
Computer by using the theory of permutation and combination to the weighing unit automatic optimum combination of the amount of load, it is concluded that a better, closer to the combination of quantitative values for packaging.
Jia wei of a more than 10 head microcomputer combination known as example, each weighing unit for weighing, and that data into the computer, the weight of each weighing hopper by computer optimization combination, according to the principle of combination of mathematics and computer technology, ten weighing unit can achieve 1023 kinds of combinations, computer is chosen from among the 1023 kinds of combination is close to the combination of the objective weight values.
Long microcomputer combination according to digital processing performed by specialized computer chips, it ensures the weight analog signal after rapid digital filter is converted into digital signals, and of ensuring we'll have time to finish described earlier 'secondary data sampling' function.
As a result of the stepper motor control of weighing hopper opening and closing speed, the size can be adjusted, and can be weighed when small weighing hopper opening and closing of the switch to smaller, in order to achieve high speed.
And vibration amplitude of the vibration slot time is adjustable, and adjust the subtle, can satisfy the requirement of accuracy and speed.
Long microcomputer combination said another important characteristic is according to the different materials have corresponding application technology, such as waterproof, fragile thing, easy to stick type material, mixing, the number of weighing, etc. , can apply to the needs of the various aspects.
Combined quantitative weighing scale section is the key to food factory automation production equipment, before our country are rely on Japan, Australia and other countries import, because the price is expensive, hindered the bull microcomputer combination according to extensive application and popularization.
Now jia wei USES advanced computer combination of component and component, its stable performance, good faith service, more close to the domestic food terminal price, has won the favour of a lot of food manufacturers and praise highly.
