Today's industrial production and daily life is inseparable from the weighing, and with the development of production, the weighing accuracy improving, especially in the packaging, food, chemical, pharmaceutical and other industries, are required to have high weighing precision.
By mechanical structure to realize high precision weighing device, not only complicated structure, and support (
Blade and knife)
Weak and easy to wear and corrosion, strict in work environment, maintenance workload is big, the big weakness is weighing speed slow, low efficiency, and can not adapt to the needs of the development of production.
In the last century 60 s, people developed a kind of electromechanical combination electronic scale, it is composed of lever system, grating device and circuit of three parts.
Lever system under the action of load, displacement, grating device converts the displacement into electronic circuit, digital signal after combination according to manufacturer with digital instrument shows a weight value.
Combination according to manufacturer this scale than mechanical lever scale enhanced precision, use more convenient, the weight values available digital visual display, and weighing signal can be transmitted over a long distance.
Already grow very quickly, more quantitative packaging scale is not only a single individual, but gradually adapt to market changes, into the production line from all walks of life.
Can realize the quantitative measurement, automatic bag, automatic sealing, land, plastic, printing, automatic palletizing and flexible combination of the integration process.
Flexible application of quantitative packing scale, also make the whole production process more simplified, operation more convenient also.
Combination said the factory to talk more and more industry production packaging can be used to quantitative packaging scale.
Such as food, feed, food, seeds, and chemical industries, if only use artificial packaging, not only the efficiency is slow, and the effect is not ideal, can lead to supply on the market demand, so this is also directly to quantitative packaging scale can provide a rapid promotion in the market a lot of room to grow.
The enrichment of material life and snacks are no longer exclusive to children, a lot of office worker always love snacks on the side.
According to statistics, in 2011, our country leisure food sales have more than 200 billion yuan, and is growing at 15% a year.
Authorities forecast that by 2018, our country leisure food with annual sales of up to 480 billion yuan.
It is clear that the development of Chinese snack market potential is tremendous.
