The air inflation shaft air bag has the function of balancing the force pressure, so that it can evenly distribute the pressure. It usually takes only about 2 seconds to complete the inflation and deflation process, and the steps to place the coil are very simple and practical, not dangerous.
The slip type air expansion shaft mechanism is designed with special functions. The air method is used to make the slip shaft move. It is suitable for all kinds of thick, thin, wide and narrow products.
All machines and equipment used for winding and unwinding can be used for air expansion shaft. The inflatable shaft can be as long as six meters or more, and as short as hundreds of millimeters, depending on customer needs.
The convex key air expansion shaft, key bar air expansion shaft, claw air expansion shaft, claw key air expansion shaft. The main body of the convex key air expansion shaft is made of high-quality steel pipe, with chrome plated surface, and the aluminum convex key is flexible
The use of inflatable shaft is very wide. Any machine with winding, unwinding and slitting can be used for inflatable shaft, even in light metal industry. For example, the inflatable shaft is mainly used for printing equipment, such as: drying machine, flexographic printing machine, concave machine, trademark printing machine, etc; Other machines include: coating machine, leather machine, setting machine, embossing machine, slitting machine, die-cutting machine, rewinder, paper cylinder machine, bag making machine, laminating machine, film covering machine, film blowing machine, foaming machine, film coating machine, embossing machine, paper machine, non-woven machine, cloth inspection machine, bronzing machine, battery equipment and other related mechanical supporting applications
It is applicable to winding and unwinding shaft of the related machines in coating,cutting,printing,compounding,paper making,bag making,plastic items,specially the occasion of the high-efficient roundness required or surface winding and unwinding of the paper tube.Moreover,it also can improve efficiency and quality of the products.
The air expansion (expansion) shaft is based on the principle of air compression to change the outer diameter of the shaft, which is closely combined with the coil, facilitating the delivery and coiling of the whole roll of materials, and promoting the reasonable, simple, accurate and automatic operation of the production line. It is widely used in the packaging, plastic and printing of vacuum aluminizing machine, slitting machine, rewinder, laminating machine, coating machine, wet duplicating machine, extrusion duplicating machine, printing machine, etc., as well as the reeling and unwinding of paper industry.
As a special equipment for winding and unwinding, air expansion shaft is usually used together with magnetic powder brake, magnetic powder clutch and tension controller. It is widely used, such as the winding and unwinding system of coating machinery, slitting machinery, cross cutting machinery, laminating machinery, film covering machinery, film blowing machinery, paper making machinery, non-woven fabric machinery, cloth inspection machinery, etc
The main body of the air expansion shaft is made of high-quality steel pipe, with chrome plated surface and aluminum alloy convex key. Strong bearing capacity, flexible key expansion and contraction, high-quality rubber liner and quick inflation nozzle, good sealing effect, long service life, removable shaft head, easy maintenance. The utility model is suitable for the use of the winding and unwinding device for winding materials, and can effectively improve the work efficiency.
It is suitable for the retractable shaft of coating, slitting, printing, rewinding, laminating, paper making, bag making, plastic and other related machinery, which can effectively improve work efficiency.
It is suitable for the retractable shaft of coating, slitting, printing, rewinding, laminating, paper making, bag making, plastic and other related machinery, which can effectively improve work efficiency.
The inflating operation time of the air expanding shaft is short. It takes only 2 seconds to separate and place the inflatable shaft from the paper tube to complete the inflation and deflation, and it does not need to separate any parts at the end of the shaft to tightly engage with the paper tube; The paper tube is placed simply: with the action of inflation and deflation, it can move and fix any position of the paper tube on the shaft surface.
The air inflation shaft air bag has the function of balancing the force pressure, so that it can evenly distribute the pressure. It usually takes only about 2 seconds to complete the inflation and deflation process, and the steps to place the coil are very simple and practical, not dangerous.
Technical parameters of expansion hose:
Sealing hole directly 30-120mm (can be processed according to user requirements)
Working pressure 1-8MPa (can be processed according to user requirements)
Starting pressure of safety valve 0.4-0.5MPa
Working flow: 4-4.5 tons of water can be injected per hour
Sealing depth 1-8m
Hose expansion coefficient 60%
The air expansion shaft is driven by high pressure gas. It controls the surface bulged shaft by inflating and deflating air to achieve the control of the surface expansion and tension of the shaft. The air expansion shaft is used in the special reeling and unwinding equipment to facilitate loading and unloading, save time and improve work efficiency. Also called air pressure shaft, expansion shaft, inflation shaft, inflation roll, inflation shaft, pressure shaft, inflation roll, etc.
