2. Development Overview

The intelligent multihead weigher was produced in Japan in the 1970s. It consists of multiple weighing units with independent feed and discharge structure. The computer uses the principle of permutation and combination to automatically optimize the combined calculation of the load of the weighing unit to obtain the best 3. The weight combination closest to the target weight value is weighed. With the passage of time and the development of load cell technology, intelligent combination scales have evolved from analog signal combination weighing to digital signal combination weighing. Due to the characteristics of a high degree of automation, saving labor costs, fast weighing speed, and very high dynamic accuracy, the intelligent combination scale has reached 12,000 global sales in 2011. The intelligent combination scale is mainly suitable for various granular, flake, strip, spherical, irregular shape, and other items that need to be weighed quantitatively. From the application industry, the intelligent combination scale is mainly used for quantitative weighing of food, Chinese medicine, seeds, tea, feed, chemical, and other materials.

China's intelligent multihead weigher industry started in 2004. After years of development, it has become a complete industrial chain integrating core technology, independent research and development, large-scale production and sales, and a number of large-scale enterprises with international production levels have emerged, such as Highdream. Smart, Guangdong Kenwei, etc. Due to the high weighing accuracy, fast speed, stable performance, and price of about 1/2 to 1/3 of the products of developed countries, China's intelligent combination scale products are exported to Europe in addition to meeting the domestic market. , South America, Southeast Asia, Middle East, Africa, and other countries and regions, have a greater influence in the world's intelligent combination scale market.

3. Status of application areas

At present, the application industry of intelligent combination weigher in China is mainly food manufacturing, pharmaceutical industry, refined tea processing, seed industry, and other industries. The food industry is the main application industry of intelligent combination weigher. According to statistics, the market demand for smart combination weigher in China's food processing and manufacturing industry occupies 78.77% of the application market for smart combination weigher, and the demand for other industries is relatively small. At present, the domestic market demand for intelligent combination weigher in the Chinese medicine industry, seed industry, tea industry and other industries accounts for 5.37%, 4.38%, 3.59%, and 7.90% of the total market demand, respectively. industry. In the future, the intelligent multihead weigher will be applied to a greater extent in the fields of Chinese medicinal materials, seeds, tea, feed, chemicals, hardware, etc., and there is more room for development.

4. The competitive landscape of China's smart combination weigher market

In the smart combination scale market, the industry is fiercely competitive. Leading foreign companies to include Ishida (ISHDA), Yamato, Anritsu, MULTIPOND Wagetechnik GmbH, Cabinplant A / S, Denmark, and Masipack, Brazil. Weighing technology, enterprise-scale, product quality, brand awareness, marketing service network, and other aspects are in the leading position in the industry and have strong competitive advantages worldwide.

China's combination weigher industry started in 2004. After years of development, it has become a complete industrial chain integrating core technology, independent research, and development, large-scale production, and sales. Among domestic enterprises, products such as Highdream Intelligence and Guangdong Kenwei are leading. These enterprises started later than foreign enterprises, but by continuously improving their technical level and product quality, they gradually narrowed the gap with foreign enterprises In terms of product cost performance, it occupies a large competitive advantage. The products of domestic enterprises have been exported to many countries and regions, occupying a certain market share in the global intelligent combination scale market. For example, the intelligent combination scale of Guangdong Kenwei Intellectualized Machinery Co., Ltd. has been exported to more than 90 countries and regions around the world, serving more than 1500 customers worldwide. Others are mainly small-scale production enterprises. Due to the barriers of technology, brand, manufacturing capacity, and capital formed by the development of the industry, most of these small enterprises do not have a competitive advantage. (As shown in Table 1 )
