With the rapid development of modern industry, packaging industry in packaging accuracy, packaging speed, packaging range and other aspects of higher requirements, the traditional quantitative automatic packaging scale has been difficult to meet these requirements, and computer multihead weigher is developed under this situation, the difference between it and the traditional quantitative automatic packaging scale are the following : First,difference in weighing accuracy caused by different weighing principles. a. different weighing principles Quantitive auto packaging scale weigh the products meanwhile put the material in it until it reach the final weighing value preset.But  there are different size and weight of the products.When the products is big size or heavy weight,the weight value will be error. 　　

Combination scale also named multihead weigher,it is consist with many independent hopper which is dumping and outputting.There are 8 to 32 weighing units in a multihead weigher. The computer select several ones whose weight is the same as the weight preset.These units are selected random.If the multihead weigher has 10 head,there is total 1023 solution to weigh the material,that means,1023 kinds of weight can be choose.Computer choose one of them. The one’s weight is same as the weight we want. 　　　

That is the right invention, combination scale b.weighing data varity The vibration to the loadcell will effect the weighing result as error.But multihead weigher supply material via feed bucket not loadcell,so the final weighing result will be more accuracy. c.quantitive packaging machine has another disadvantage.That is dropping weight will effect the weighing result.So there will be a error.Combination scales don’t have such problem. This error is obvious in the Quantitative automatic packing scale. 2.Weighing speed difference Combination scale packaging speed is 6 times as the speed of tranditional quantitive packaging scale. 3. material weighed scope As the same accuracy, material scope processed by combination scale is much wider that that of quantitive scale. In the same accuracy,multihead wheigher weghing scope will be much wide than Quantitative automatic packing scale’s.The weight scope Quantitative automatic packing scale  can weigh is around the 4 times of it.but it can be 10 times that of multihead weigher.  To keep the same accury,Quantitative automatic packing scale need to shorten the weighing scope with many of it ,it can do that .Multihead weigher can resolve it easily. 　　　

Although the combination scale is very competitive, it is mainly imported from other country.Its high price block its purchase in China and the rest of the world.        　　

Guangdong Kenwei Intellectualized Machinery Co.,LTD. has now become a large-scale manufacturing base of China composite scale. Kenwei has the connotation of stable time model, international well-known sensor matching, ad conversion module and anti-jamming technology integration, to overcome how to improve the amplitude and amplitude of how to continue the two major issues of long-term vibration machine structure, with the industry's higher level of complete quality and R & D Laboratory, the above actions of the overall control, So that the quality has always been in the industry reputation, Wei has a complete weighing packaging, weight selection, metal and foreign body testing, manipulator automatic sorting palletizing industry chain, at the same time for a variety of materials, such as bag bags, large number of materials, long strips, cheese, salad, noodles, chopsticks, hardware, oil fish, fragile, easy to dust, frozen food , viscous materials, etc., in view of the above materials to fully consider the market maximum and minimum packaging specifications to establish a complete series, and constantly develop a dedicated line for aluminum foil packaging and soy sauce Packaging metal Detector, pharmaceutical industry several special dual-Channel 8-track electronic digital granulator, suitable for the overall rear section of the manipulator automatic sorting palletizing industry chain. 　　

The production of Kenwei combination scale and the its popular,make the kenwei combination scale "professional quality, Integrity marketing" business positioning by more foreign agent customers know. Product workmanship more exquisite, parts selection is very sophisticated, a set of strict implementation of product testing and aging system, thus ensuring the high quality of kenwei  products, and constantly develop new products suitable for agents, to ensure that customers with marketable products, thereby reducing customer input costs in the service, which is the embodiment of the professional market of Kenwei Company ; From the customer's point of view to think about the problem, the customer to carry out a comprehensive technical, marketing and service support, strict implementation of the agency system and abide by the commitment to reduce the customer's worries, this is Kenwei’s honest. Kenwei combination scale in the technical aspects of the continuous rise, so that originally regarded as "aristocratic products" of the computer combination scale no longer become the patent of large enterprises, more and more pursuit of high speed, efficient food enterprises at home and abroad, have eliminated the past manual quantitative weighing packaging production line, so as to adopt high-tech, More automated combination scales quantitative weighing packaging system to arm yourself.
