What Is The Difference Between The Gas Rising Shaft And The Mechanical Shaft?

The gas rise shaft is also called the inflation roll, which is a kind of winding and unwinding which is common in the paper coating and printing industries. After the compressed air is inflated, the key strip on the surface of the shaft can be raised (the shaft diameter is increased), and the key strip on the surface after deflation is quickly retracted (recovery of the shaft diameter) for tightening the core.
The difference between the gas rise axis and the mechanical axis is reflected in the following five aspects:
1. The air-inflating shaft has a short operating time, and the separation and placement of the gas-increasing shaft and the paper tube can complete the inflation and deflation in only 3 seconds, and it does not need to separate any parts on the shaft end side, that is, it can be tight. And the paper tube bite.
2. The paper tube is placed in a single position: in the action of inflation and deflation, the paper tube can be moved and fixed at any position on the shaft surface.
3, the carrying weight is large: according to the actual needs of customers, to ensure 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 special, and it can be applied to all kinds of paper tubes with thick, thin, wide and narrow.
5, simple maintenance, long use time: gas rising shaft is a single part, each part of the structure has a fixed specification, can be used interchangeably, easy to overhaul.
Strictly speaking, the air-up shaft is easy to use, but it is not stable compared to the mechanical axis, and has its own advantages and application fields.


The use method and technical characteristics of the inflation shaft
Instructions:
The cantilever expansion shaft is better than the normal inflation shaft. It is not necessary to remove the whole shaft after the second discharge. After the gas is directly deflated, the material can be taken away. Since its width is not large, the natural operation is also More convenient, this is also the inflation shaft selected by many machines with light weight and small width. Only the inflatable handle is inflated against the air nozzle on the inflation shaft to complete the sliding air core, which is deflated, and the key bar will return to the original posture.
Technical features:
The entire metal frame excavates a box-type window at the fixed end of the cantilever mandrel operating side to ensure the structural rigidity of the printing channel. The bearing seat device is inside the movable steel block, and the steel block is made of high-precision ball wire. The rod is driven, and the moving position of the screw is on the base line of the plate mandrel, and the linear guide rail is fixed at the upper and lower ends of the box window to fix the movable steel block, thereby ensuring the stability of the printing channel in high-speed operation.
In this design, the fixing of the mandrel is completely automatic, and the movement of all the screws and the determination of the shaft end eliminate the artificial elements. The moving steel block is fixed to the frame through the upper and lower linear guides, and the screw is The roller core shaft moves on the base line, and the thrust of the base impression cylinder against the plate roller and the driving force along the direction of the ball screw are applied to the base of the plate roller core shaft, which only constitutes a small part of the pressure, and due to the force The load acts only on the base of the plate mandrel and there is no torque on the support frame.
