What Is The Principle And Characteristics Of The Analytical Air-swelling Shaft Of The Slitter?

Slitting machine is one of the main independent equipments of mechanical enterprises. The performance and difference of its function directly reflect the level of product quality and production efficiency. The function of the reel on the machine determines the function of the slitter is good and bad. At present, most of the slitting machines used by China's machinery enterprises are mechanical slip shafts and ordinary air shafts, and the slip air shaft is used less. Below we introduce the gas shaft manufacturer:
    The mechanical slip shaft consists of three parts: the optical axis and the slip sleeve and the compression spring adjustment mechanism. The working principle is to adjust the torque force of each slip sleeve on the shaft by pressing the pressing force of the spring adjusting mechanism at both ends of the shaft. Because the structure is that the mechanical pressure is transmitted from both ends of the shaft, the pressure of each slip sleeve is not uniform, so the torque force of each slip sleeve can not be adjusted fully with the change of the tension required for the material change, the slip sleeve The relative sliding is not good, and it is easy to produce irregular winding, broken strips, loose rolls, and unwinding, resulting in material loss. The winding speed is low. When adjusting the pressure, it must be stopped and adjusted to affect the working efficiency.
 The inflation shaft is a special type of winding and unwinding, that is, the shaft that can be raised by the outer surface after the high pressure is inflated, and the shaft whose outer part (referring to the key strip) is rapidly retracted after deflation is called gas. Expansion axis. The classification of the slitter is also called the pneumatic shaft, the contraction shaft, the inflation shaft, the inflation roller, the inflation shaft, the pressure shaft, and the inflation roller.

    The air expansion shaft and the air expansion sleeve are extremely convenient and quick to use. Only the self-prepared air source is required. The air pressure is controlled within the range of 6-8kg/cm2. When the external components (such as a circular paper tube) need to be locked, only The inflatable handle can be completed by inflating the air nozzle on the inflation shaft, and the key bar will protrude against the external component (such as a circular paper tube). When the paper is unloaded, the sliding on the air nozzle is pressed by hand. The air core is deflated, the key strip will return to its original appearance, and the external parts (such as a circular paper tube) can be taken out.

    Classification of the air expansion axis: the inflation axis is divided into a bulging type air expansion shaft, a plate type air expansion shaft, an aluminum alloy air expansion shaft, a gas nail shaft and the like.

    1. The inflating operation time is short, the inflation shaft and the paper tube are separated and placed in just 3 seconds to complete the inflation and deflation, and it is not necessary to separate any parts on the shaft end side to be tightly engaged with the paper tube.

    2. The paper tube is simply placed: in the action of inflation and deflation, the paper tube can be moved and fixed at any position on the shaft surface.
 3, the bearing weight is large: according to the customer's practical needs, to determine the size of the shaft diameter, and the use of high-hard steel, so that its load bearing increased.

    4, high economic efficiency: The design of the shaft is a special function, all kinds of paper tubes for thick, thin, wide and narrow can be applied.

    5, simple maintenance, long use time: the inflatable shaft is a single part, each part of the structure has a fixed specification, can be used interchangeably, so that it can be repaired.

    Therefore, the mechanical slip axis is solved, and the problem of broken strips, loose rolls, unwinding, etc. caused by the change of the unevenness of the material thickness during the winding of the common air-expansion shaft is avoided, thereby avoiding the material loss caused thereby. And can collect large and small rolls at the same time on the unified slip air shaft. The winding speed is higher. Because the air pressure can be adjusted without stopping, the machine adaptability and work efficiency are greatly improved.
