Cantilever Type Air Expanding Shaft

The cantilever inflation shaft is a special type of winding and unwinding, that is, the shaft that can be raised by the high pressure inflation surface (the key strip), and the shaft whose surface portion (referring to the key strip) is quickly retracted after deflation is called a cantilever. Shafts. The structure of the cantilever air shaft is widely used in many mechanical industries, especially in the film industry.
In this design, the fixing of the mandrel is completely automatic, and the movement of the entire screw and the locking of the shaft end eliminate the human factor. The movable steel block is fixed to the frame by two upper and lower linear guide rails, and since the screw rod moves on the center line of the shifting roller core shaft, the central impression cylinder can understand the thrust of the plate roller and the driving force along the direction of the ball screw. At the center of the plate mandrel, only a small partial pressure is formed, and since the force load acts only on the center of the plate mandrel, there is no torque on the support frame.

Instructions
The cantilever expansion shaft is better than the general inflation shaft. It is not necessary to remove the entire shaft during the second discharge. After the gas is directly deflated, the material can be removed, because its width is not large, so the natural operation is more convenient. This is also the inflation shaft selected by many machines that are light in weight and small in width. The air expansion shaft and the air expansion sleeve are extremely convenient and quick to use. Only the self-prepared air source is needed. The air pressure is controlled within the range of 6-8kg/cm2. When the external components (such as a round paper tube) need to be locked, as long as the air is inflated. The 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 gas on the air nozzle is pressed by hand. The core is deflated, the key strips return to their original appearance, and external parts (such as round paper tubes) can be removed.

The largest structural feature of the inflation shaft is that it has a continuous undivided shape, and the slip shaft is usually connected by a segmented inflation unit. The outer layer of the inflation shaft is an inflatable sleeve, and both ends of the inflation sleeve are sealed by a sealing ring. The inflatable sleeve is internally wrapped with a key strip, an inflatable sheet, a central shaft body, and the like. The air pressure enters from both ends of the inflation shaft, and the pressure can be controlled to control the protrusion and contraction of the key strip. When the key strip or the expansion tab protrudes, the inflation sleeve has a frictional force, and the animal material is wound up.
 
Since the inflation axis is continuous, the generation and disappearance of the frictional force on the inflatable sleeve are uniform, and it is impossible to control the friction of a single point, so the inflation shaft has no slip function. The inflation shaft can have numerous protruding points, and the frictional force can be designed according to the needs. Because of this, the inflation shaft is more suitable for the winding of materials with relatively large areas and relatively high quality.
