New Characteristics And Main Functions Of The Inflation Shaft

 The inflatable shaft is suitable for striping, printing, rewinding, coating, laminating and other mechanical cooperation that requires high roundness or surface winding. It is a special type of winding and unwinding, that is, the axis that can be raised by the surface after high pressure inflation (the key bar), and the axis that the surface part (referring to the key bar) is quickly retracted after deflation is called the inflation axis.

      Its name is diversified, also known as pneumatic shaft, expansion shaft, inflation shaft, air expansion roller, inflation shaft, pressure shaft, air expansion roller, etc., although the name is more, but the working principle is the same. Inflatable shaft, inflatable sleeve use It is extremely convenient and fast. It only needs to be self-contained. The air pressure is controlled within the range of 0.5-0.8 MPa. When it is necessary to lock the external parts (such as a round paper tube), as long as the air gun is facing the air nozzle on the inflation shaft. The inflation can be completed, and the key bar will protrude against the external parts (such as a circular paper tube). When the paper is unloaded, press the sliding air core on the air nozzle to deflate, and the key bar will return to The original appearance, external components (such as a circular paper tube) can be taken out of the professional production of inflatable shaft, maintenance of the inflatable shaft, the principle of the inflatable shaft, although the inflation shaft is called, but the working principle is the same. The inflatable sleeve is extremely convenient and quick to use. It only needs to be self-contained. The air pressure is controlled within the range of 0.5-0.8 MPa. When the external components (such as a circular paper tube) need to be locked, as long as the air gun is inflated. The air nozzle on the shaft can be inflated, and the key bar will protrude against the external parts (such as a round paper tube). Hand pressing the slide core gas, i.e. the gas mouth deflated, will return to the original spline way, external components (such as a circular paper tube) can remove air shaft specializing in the production, repair air shaft,

       The main function of the inflation shaft is a high-precision air-expansion shaft that has been carefully designed to shape. It is suitable for the uniform coating of the key type air expansion shaft, the slat type air expansion shaft, the flange type air expansion shaft, the release layer, the color layer, the glue layer and the imaging layer. Achieve the effect of synchronous operation. This product has the advantages of high control precision, fast response, stable machine control and no damage on the finished surface.

      The drying system of the air-expansion shaft integrates the air-expanding shaft, the key-type air-expansion shaft, the slat-type air-expansion shaft, and the flange-type air-expansion shaft drying box to improve the design, and the drying energy-saving, environmentally-friendly, high-efficiency, It can be separated and cleaned separately.

      The inflatable sleeve (also known as the expansion joint sleeve, the keyless bearing, etc.) is a keyless coupling device whose principle and use is through the action of high-strength tension bolts, between the inner ring and the shaft, the outer ring and the hub. A huge tightening force is generated to achieve a keyless connection between the machine and the shaft. When the load is applied, the combined pressure of the expansion sleeve and the machine member and the shaft and the accompanying friction force transmit the torque, the axial force or a composite load of the two.

      The expansion sleeve of the inflatable sleeve is a long strip of the through-axis, no segmentation, so there is no slip function. There is no corresponding slip action when the tension changes due to the material change when the strip is cut. When the tension changes or the material thickness is not thin When it is even, it is easy to cause uneven winding, broken strips, loose rolls, and unwinding, resulting in material loss. The winding speed is low, and the work efficiency is poor. The same axis cannot receive the large and small volumes at the same time.

      The tension control system of the inflation shaft is mainly composed of a controller, a reader, a brake, a clutch, and a detector. It is often a system integration of sensors and controllers. Magnetic powder clutches are currently mainly used in weaving, papermaking, film, plastic, dyeing and finishing, wire, metallurgy and other equipment. It is an automatic control of constant tension or taper tension. Control System.

      1. According to the monitoring methods of different coils, it can be divided into ultrasonic type, floating roller type, tracking arm type and so on.

      2. According to the loop of the inflation shaft, it can be divided into: open loop, closed loop or free loop tension control system;

      Whether the tension control of the inflation shaft is stable or not is directly related to the quality of the slitting product. If the tension is insufficient, the raw material will drift during operation, and the finished paper will wrinkle after slitting and rewinding; if the tension is too large, the raw material will be easily broken, so that the finished paper breaks after slitting and rewinding.
