In recent years, China's packaging machinery industry has achieved rapid development, but there have also been some phenomena of low-level redundant construction. According to relevant data, compared with industrialized countries, China's food and packaging machinery products lack 25% to 30%, and the technological level is 15 to 25 years behind. Experts believe that the low level of repeated construction of packaging machinery has hindered the upgrading and innovation of the industry's products, and it should be resolved. However, the natural elimination can only be achieved through market regulation and strengthening the supervision of its downstream industry, the food industry. Experts predict that the future development of China's packaging machinery market will present the following characteristics:
First of all, the technological content of packaging machinery is increasing day by day. Some existing packaging machinery products in China have low technical content, and many advanced technologies have been applied to packaging machinery abroad, such as remote-distance remote control technology (including monitoring), stepper motor technology, automatic flexibility compensation technology, and laser cutting technology. Information processing technology.
Second, the packaging machinery market has become increasingly monopolized. At present, apart from corrugated paper box packaging machinery and some small packaging machines in China, there are certain scales and advantages. Other packaging machines are almost unsystematic and large-scale. In particular, some packaged-packaging production lines with large demand in the market are all in the world packaging market. The monopoly of large packaging machinery companies (groups).
Finally, the production of packaging Machinery Parts is specialized. The international packaging industry attaches great importance to improving the general capacity of packaging machinery processing and the entire packaging system. Therefore, the specialization of packaging machinery parts production is an inevitable trend of development. Many parts and components are no longer produced by the packaging machinery factory, but by some common standard parts. Factory production, some of the special components produced by highly specialized manufacturers, the truly famous packaging machinery factory may be an assembly plant.
The suspension system is floorboard of the connection device between the frame and wheel axle or all the force, its function is to transfer function between the wheel and the frame of force and moment, and buffer by the uneven road surface to the impact of the frame or body, and the attenuation of the resulting vibration, in order to make sure the car was going smoothly.
In general, the automobile suspension system can be divided into the independent suspension and independent suspension, the independent suspension of the wheels on both ends of a whole axle, when the wheel side beat the other side wheels also beat accordingly, make whole body vibration or inclination;Independent suspension axle is divided into two sections, each wheel under the spiral spring independent by the installation of the frame, when the side wheels to beat the other side of the wheel is not affected, can the wheels on both sides of the independence movement, improve the stability and comfort of a car.As people demand for the car ride comfort and manipulation stability becomes more and more high, the independent suspension system already was washed out gradually
