Full automatic packing scale is a kind of packaging machinery, in the packaging industry occupies the position of play a decisive role and value in use, it provides the necessary technical equipment in the packaging process, the finished products. Although the packaging machinery production in the whole packaging industry in the proportion of less packaging materials, does not belong to a regular consumables, but integral to the packaging industry modernization is support. Without modern packaging machinery, no packaging industry modernization. Packaging machinery as a professional machinery, in addition to more than the general requirements general machinery, but also has beautiful appearance, compact structure, smooth operation, transmission device of high precision, high production efficiency, to perform well in its function, to meet the market demand. Full automatic packing scale is a great potential for development of packaging machinery. With the continuous progress of science and technology, many new technologies have been applied in the automatic packaging machine. As peoples consumption concept is changing, the packing of the goods to the crucial impact on peoples purchasing behavior, many enterprises have to pay attention to the full automatic packing scale. Quantitative scale of production enterprises of our country on a small scale, product design, research and development of component is very weak. Quantitative packaging industry in China in the past in a long-term low level of productivity, the main technology is not high situation, most enterprises are still in each others internal and external technology copy copy, the original management stage to reduce production cost. Some artisanal small enterprises with a set of drawings of survival, blindly pursue low-cost, seriously disrupting the domestic market. Enterprises do not have independent intellectual property rights, especially the control of the core technology, the controller is quantitative packaging machinery of the brain, most enterprises are required to buy from foreign or joint ventures, wholly foreign owned enterprises. At present, the quantitative packaging equipment in China has entered a new period of adjustment of product structure, improve the ability to develop. Technology upgrading, product upgrading is an important topic in the development of the industry. Low level development will influence the quantitative packaging machinery to the whole The rapid development of a quantitative packaging industry, so must strive to change the backward situation. To strive for greater domestic and international market. Quantitative packing scale by weighing unit, trolley, sewing and conveying device, a pneumatic system, dust removal system, composed of quantitative packaging control instrument etc. The key component influencing the speed and accuracy of the package is weighing unit, which comprises a storage silo, gate, a cut-off device, the scale body, a bag clamping device, stent, electrical control device. A storage bin for buffer hopper, for material reserve and provide a nearly uniform material flow; the gate is located at the bottom of the storage silo, when equipment maintenance or failure occurs, for the material blocking in the storage bin; a cut-off device consists of a cutting hopper, cut-off gate, pneumatic components, air door, to provide fast, slow two feeding levels in weighing process, the fast, slow feeding material flow can be adjusted separately, so as to ensure quantitative packing scale to meet the accuracy requirement of measurement and speed requirements; air door for balance weighing system air pressure; the scale body is mainly composed of a weighing hopper, bearing bracket and the weighing sensor, complete the weight to the signal transformation and transmission to the control unit; a bag clamping device is mainly composed of a bag clamping mechanism, pneumatic components such as the composition, role for the packaging bag tightly, let all the material weighing completed into package bags; electric control device comprises a weighing display controller, electrical components, control cabinet composition, function control system for work, make the whole system according to the preset program, orderly work. Quantitative packing scale by weighing method can generally be divided into a bucket (net) scale and no bucket (GW) scale. A hopper scale work will need to weigh the material through the feeding device is added to a weighing sensor for measuring weight balance. A hopper scale bearing device is a hopper, discharging device installed valve in the hopper bottom is a quantitative packing scale system. However, because the packaging materials (bag) inconsistent weight, no bucket weighing system work each weighing cycle must determine the tare weighing unit changes. Therefore, in each weighing cycle must be by the computer weighing control instrument automatic peeled, because peeled occupied for several seconds, the packing speed without hopper scale of influence. Hopper can be used in the square hopper is arranged at the bottom of one or two to open the valve structure, the use of cylinder to drive the valve discharge. A bucket weighing precision, fast speed, and can be composed of two scale (and above) system, greatly improve the packing speed. No hopper scale structure saves the hopper component, the weighing sensor is installed directly in the hopper and a bag clamping device, work material directly into the folder in the folder bag institutions on pocket weighing. Because there is no hopper scale omits the hopper component, greatly reduce the scale body height, suitable for packaging of the low. With the development of science and technology, all kinds of food, aquatic products, put forward new demands on food packaging technology and equipment. At present, food packaging machinery increasingly fierce competition, the future food packaging machinery will coincide with the industrial automation, promote improve the overall level of packaging equipment, food packaging equipment the development of multi-function, high efficiency, low consumption. Most enterprise annual output value of several million yuan to 10000000 yuan, 1000000 yuan less than a few enterprises still. Nearly 15% of the enterprises production or closed down every year, but 15% of the enterprises to join the industry, extremely unstable, hindered the stability of the development of the industry. To adapt to the international market demand, development of green packaging machinery. After joining the WTO, the international packaging machinery industry competition is becoming increasingly fierce, foreign green trade barriers put forward higher requirements on food packaging machinery industry, therefore, must change the traditional packaging machinery design and development model, Taken into consideration at the design stage to make the packaging machinery in its whole life cycle (design, manufacture, assembly, use, repair and waste disposal processes) no effect or impact on the environment, resource consumption minimization, easy recovery and green, to enhance the core competitiveness of Chinas packaging machinery.Full automatic packing balance premise of continuous development in the packaging industry, under changing. New product development from research imitation tracking situation, has strong competitiveness, stimulate economic growth, improve the efficiency of. But there are some packaging machinery enterprises has not yet been achieved extensive management, fine management, between some packaging machinery enterprises in peoples cognition and use and the law of market economy does not adapt phenomenon. Full automatic packing scale has: 1, simplicity, automation. A new type of packaging machinery in general have a multifunctional, adjust the operation is simple, mechanical and electrical integration is the new trend of packaging controller. Full automatic packing scale will coincide with the industrial automation trend, new equipment and technology has gained popularity. Manufacturing enterprises will tend to purchase packaging machinery operation simple and easy installation, especially in the manufacturing industry a large number of layoffs, the simple operating system demand will grow with each passing day. Structure from motion control is related to the performance of packaging machinery. 2, high productivity. Packaging machinery manufacturers pay more and more attention to packaging equipment development rapid, low cost, the future trend of development is the device smaller, more flexible, versatile, high efficiency. This trend is also included to save time, reduce costs, so the packaging sector is pursuing combination, concise, removable packaging equipment. In the packaging machinery automation, automation program has gained wide application. 3, complete and perfect. Only attach importance to the host production, without considering the equipment complete, will make the packaging machinery should function can not play. Therefore the development of related equipment, so that the host are the biggest expansion, improve market competitiveness and economic factors is essential equipment. Machiner. Machinery manufacturing enterprises focus on complete integrity in with automatic production line or production line equipment for the user, both high technical additional value or a simple equipment, according to the compatibility of requirements. Packaging industry the most urgent is to change the way to develop the enterprises packaging machinery industry, enterprises should stand up to examine and solve the contradictions and problems above in the new starting point, change the idea of development, strengthening the independent innovation, strengthen market awareness, and vigorously promote the development of domestic packaging machinery industry. To change the packaging machinery industry status, promote the development of packaging machinery industry at the same time, stride to the attention of the development trend of packaging machinery. Full automatic packing scale must develop more new features, innovation in order to occupy more market, the latest developments to understand the whole industry, cultivate leading eyes and sensitive market insight, these are so that automatic packing scale walk in the forefront of the market essential ability. Automatic packing scale to bring the gospel to many enterprises. Constantly improve the level of automation in the manufacturing industry, the application scope is expanding.
