| China’s packaging machinery industry in the development of three major trends analysis |
| In recent years, China’s packaging machinery industry has made rapid development, but there are some low-level redundant construction phenomenon. According to the information shows that compared with industrialized countries. China’s food and packaging machinery products varieties lack 25% ~ 30%, technical backwardness of 15 ~ 25 years. Experts believe that the packaging of low-level redundant construction machinery industry to the upgrading of their products and innovations have constituted an obstacle. should find ways to resolve them. But only through market regulation and strengthen its downstream industries -- food industry regulatory efforts to achieve a natural eliminated. Experts predict : In the future, China’s packaging machinery market will show the following characteristics : First, the technical content of the packaging machinery increasing. China’s existing packaging machinery products is not high technology content, Foreign advanced technology has many applications in packaging machinery, such as remote control technology (including monitor), stepper motor technology, automatic Flexible Compensation, laser cutting technology, information processing technology. Secondly, the increasing packaging machinery market monopolization. Apart from China corrugated box packaging machinery and packaging machinery some small scale and have a certain advantage, other packaging machinery almost fragmentation and scale, particularly in market demand for the sets of some packaging production lines, in the world packaging market were several major Packaging Machinery Enterprises (Holdings) monopoly. Finally, packaging machinery parts specialization of production. International packaging industry attaches great importance to improve the processing and packaging machinery as a whole generic packaging system, So packaging machinery parts production specialization is the inevitable trend of development, many parts removed from the packaging machinery factory production, but by some common standards Component Factory production, as some special parts from highly specialized production factories. really well-known packaging machinery plants will likely be an assembly plant. Multifunction products to a single, high-speed bipolar development. The final packaging machinery is to increase production efficiency and product diversification. New technology boost packaging machinery industry is the development of packaging products to enter the field of flow conditions necessary and the realization of the packaging is the primary means of the use of packaging machinery. With the development of the times and advances in technology, packaging machinery in the circulation area of the Chiang Kai-shek have been playing an increasingly big role. Traditional packaging machinery used mechanical control, such as the distribution of coaxial Cam, and later appeared electronic control, photoelectric control, Aerodynamic control forms of control. However, as increasing productivity, packaging parameters of the random variable, These control systems are increasingly difficult to meet the new situation and development. At this time, a new technology -- mechanical and electrical integration technologies emerged, it completely changed the face of packaging machinery, make it to a new attitude emerging in the eyes of the world. Electromechanical integration of the technical characteristics of the current science and technology in an era marked by new technologies, new processes, new materials, The emergence of the new equipment, is no longer a purely academic development, but the doors of related disciplines, a range of advanced technologies complement each other infiltration and results. Electromechanical integration of this technology is a new technology, it is in information theory. cybernetics and systems theory built on the basis of the integrated technology. Its essence is from the system point of view, the use of process control principles, machinery, electronics and information, Detection of related techniques such as organic composition of the overall best. Specifically, it will introduce computer technology to packaging machinery. Mechatronics fundamentally changed the look of the packaging machinery. In such packaging machinery, as its computer brain, replacing the conventional control system. Mechanical structure and its main trunk, all kinds of instruments, gauges, sensors its senses, They experience all kinds of packaging parameters of the changes, and feedback to the brain (microcomputer), the implementation of the various agencies is the hand-foot-and packaging operation to be completed by the necessary action. A complete electromechanical integration system, including general computer, sensors, the original impetus, the drive system, as part of implementing agencies. It discarded the conventional packaging machines, the cumbersome and unreasonable parts, mechanical, computer, microelectronics, Sensors such as a multi-disciplinary integration of advanced technology for packaging machinery in the design, Manufacturing and control has brought profound changes that fundamentally changed the look of the packaging machinery. On the role of packaging machinery a new technology, once turned into productive forces, often play a tremendous role. If photoelectric positioning error is much smaller than the mechanical positioning, in the dry microwave effect -- far better than dry heat and so on. electromechanical integration technology for packaging machinery on the time not long, but the result is obvious and the role is enormous. So greatly simplify the mechanical structure of the machine control system for the organ. traditional packaging machinery control system used relays, contactors control circuit, With the complexity of the implementation of the increase and the adjustment of the position rises, the machinery is getting more complicated, to create, adjust, and the use and maintenance of these inconvenient. Mechanical and electronic integration, available computer, sensor technology, a new type of drive technology to replace the cumbersome electrical control cabinet and driving device make drastic reduction of the number of components, greatly simplifying the structure, volume also shrank. Improve the quality of microcomputer products within a huge storage system, People can pre-packaging machine will affect the work of the parameters and the data are stored in the computer, it can automatically track the production process. When a number of parameters or parameters change and this change in an instant feedback to the computer, Computer on these changes parameters identification, and timely judgment amended accordingly, ready to make packaging machines remain in the best condition. And the traditional packaging machine parameters change, the adjustment more experience, which is difficult to find the best parameter; If several parameters changed at the same time, but at a loss. If the most common plastic sealing machine, sealing quality and packaging materials, heat sealing temperature and speed, and so on. If material (material, thickness) changes, temperature and speed and consequently change, but the number of difficult to grasp the changes. Using computer control, various packaging materials sealing temperature and speed of the input parameters matching the best computer memory, Reinforced with the necessary sensors, automatic tracking system component, so that no matter what changes in process parameters, able to guarantee the best quality seal. More parameters to adjust some more, electromechanical integration, the greater the advantages, which is the normal control mode could. More functional, enhanced reliability, electromechanical integration, in addition to maintaining the original packaging machine functions, but also given many other functions. Drink liquids such as flexible packaging machine, it pneumatic, electrical and mechanical works with, the system may have a case, a sterile, filling, sealing function, but the introduction of computer control system, it can also store such as production rate, product volume, fault, Data on the cause of the malfunction, taking on these data according to the actual situation accordingly, and the results printed out, or displayed on the screen, greatly facilitate the operation. Electromechanical integration will be given to automatic packaging machine monitoring, dynamic detection, alarm functions, but also has the security chain of control, Overload protection and control functions, allowing the packaging machine reliability greatly improved. |
