The Theoretical Basis Of The Development Of The Expansion Shaft And The Description Of Its Development Momentum

The development of the air-expansion shaft is based on the original traditional shaft. After long-term technical research, it continues to innovate and sublimate into a modern inflatable shaft. On the other hand, with the rapid transformation of industrialization to commercialization, large-scale Mass production is also an inevitable law of the manufacturing industry, and it is also the fundamental technical requirement of the market. If it is necessary to make the installation of the slat-type air-expansion shaft convenient, it can be used with the flange safety chuck and the shaft seat safety chuck. It can be matched with magnetic powder clutch and magnetic powder brake. The structure of the ordinary air-expansion shaft is a long strip of the through-shaft, no segmentation, so there is no slip function. There is no corresponding change in the tension due to material change when cutting multiple strips. Slip action, because of the convenient and quick use of the tile inflation shaft, the key bar type gas rise shaft has been widely used, and all the mechanical equipment related to winding, unwinding and slitting can be applied.
        The applicable value of the above related machinery has been upgraded to a new level. The air expansion shaft is used, and the user needs to self-fit gas resources, and the gas pressure is controlled within the range of 6-8KG/CM2. The automatic control technology of the air-expansion shaft mechanical industrial products has been developed to a relatively high level. The automatic control of the equipment unit, the closed-loop control of the parameters, and the online feedback control of the process are all obtained by the electronic and computer technology on the mechanical products of the inflatable shaft. For a wider range of applications, there has been an inflatable shaft mechanical product with intelligent control functions. When the tension changes or the material thickness is uneven, the winding is not easy to be wound, broken, loose, and unwound, resulting in material loss.
        Due to the frequent changes in the production of inflatable shaft products and the consideration of effective investment in operation, the customer needs the inflatable shaft machinery industry to provide the most suitable air-expansion shaft mechanical equipment. In addition, when the material needs to be unloaded, the paper tube can be taken out by pressing the gas nozzle by hand and letting off the gas in the plate type gas rising shaft. Simple occurrence of unwinding, broken strips, loose rolls, unwinding, large-scale and mass production is also an inevitable law of manufacturing. With the continuous development of China's construction machinery enterprises and the continuous development of overseas markets, The most frequently encountered obstacle to the internationalization of enterprises is political factors.
        Therefore, the air shaft machinery has become an important part of various brush machinery industry, packaging industry, electrical appliances, electronics, information industry, automotive and other transportation, agriculture, light industry, biology, medical, petrochemical, machinery, and defense industries. technical equipment. Relevant enterprises should be from the powerful enterprise itself, the automatic control of the equipment unit, the closed-loop control of the parameters, the online feedback control of the process linkage, and the company's level on the product. Because its layout is the mechanical pressure from both sides of the shaft, continuous technological innovation and innovation can On the road to internationalization, go on a smooth and long-term basis, or raise the tax amount, or in the name of “anti-dumping” or “influence on national economic security”.
        The convenience of taking out the inflation shaft from the coiled tube is achieved. The air-filling shaft matching clamp is suitable for the coiled tube with large inner diameter and the safety chuck. It can make the folding between the air-expansion shaft and the machine convenient and convenient, saving time, labor and cost. Because the inflatable shaft products are widely used in various sectors of the national economy and people's lives, they have hindered the overseas development of non-local enterprises. The uneven pressure on each slip sleeve makes the piston on the shaft eject, which affects the working power. In addition, Chinese enterprises need to tighten the paper tube or paper tube if they want to expand overseas.
        As long as the nozzle of the key-type air-expansion shaft is filled with gas by a special air-filling gun, the function of the paper tube can be tightened. For a long time, the mechanical model and functional specifications of the air-expansion shaft have not been satisfied. Market demand. The air-expansion shaft is easy to use and can be retracted freely. It takes only 3 seconds to inflate, and the air-filled shaft and the coiled tube can be tightly fixed to achieve a good winding effect. Similarly, the deflation takes only 3 seconds. The expansion shaft can be separated from the coiled tube. When importing and exporting and Chinese enterprises are stationed in the local area, the first thing to do is to adapt to international rules and familiar with the laws of investment sites, and avoid political and legal traps.
        However, China has lagged behind the western countries represented by Germany in the field of high-end inflatable shaft machinery. From the mechanical model and functional specifications of the inflatable shaft machinery, it has been unable to meet the market demand, and the winding speed is low. The difference between the efficiency and the same axis can not charge the large and small volumes at the same time, while the low-end products are relatively overproduced. The value difference between the two is extremely great. The inflation shaft leads to a large amount of profits in China's export expansion shaft machinery, but it is not enough to buy a high-end machinery. The dilemma, therefore, to improve the automation control technology of the mechanical shaft industrial machinery products and develop to a relatively high level has become a top priority.
