The pneumatic shaft is a special winding and placement shaft. The surface (referring to the keybar) can be raised after high-pressure inflation, and the surface part (referring to the keybar) retracts quickly after deflation. It has many names, such as pneumatic shaft, expansion shaft, gas expansion shaft, gas expansion roller, inflation shaft, pressure shaft, gas expansion roller, etc.
Compared with the slip shaft, the pneumatic shaft has the following characteristics:
1. Short inflation operation time: the separation and placement of the inflation shaft and the paper tube can be completed in only 3 seconds, and the inflation and deflation can be completed without any parts on the end side of the shaft, which can be closely engaged with the paper tube.
2. Simple placement of the paper tube: through the action of inflation and deflation, the paper tube can be moved and fixed at any position on the shaft surface.
3. Large bearing weight: The shaft diameter can be determined according to the actual needs of customers, and high hardness steel can be used to increase the bearing weight.
4, high economic efficiency: the shaft is designed for special functions, for the thickness, width and width of various paper tubes can meet the requirements.
5. Simple maintenance and long use time: the gas-rising shaft is a single part, and each part in its structure has a fixed specification, which can be exchanged and used easily, and is convenient for maintenance.
The slip shaft is a special segmented air shaft, independent slip and torque setting structure, which solves the unwinding phenomenon caused by uneven material thickness and tension, and effectively improves product quality and work efficiency.
The structural characteristics and principle of the slip-type air expansion shaft: The slip-type air expansion shaft is mainly composed of a mandrel, an airbag, a slip sleeve and other parts. Air enters the inside of the airbag to cause the airbag to expand, pushing each torsion group to expand outward. The slip torque value of each torsion group is set according to the inflation pressure, which is convenient to control the tension of each roll of material on the slitting machine during winding.
The slip-type gas expansion shaft is mainly used for slitting equipment with high product quality requirements and fast speed.
Technical parameters of slip type air expansion shaft: outer diameter of main body of slip type air expansion shaft Φ75mm, outer diameter of action Φ78mm, applicable paper tube Φ76±0.2mm.

What is the stability of the cutting accuracy of the web slitting machine?
A slitting machine is a common processing equipment used to cut materials into the required size and shape. Its working principle is based on the synergy of the rotating blade and the transmission device to cut the material through the cutting port. The working principle of the slitting machine can be explained by the following steps: First, the material to be processed is placed on the feed port of the slitting machine. Next, start the machine so that the blade starts to rotate. The rotation speed and strength of the blade will affect the cutting effect. After the material is fed into the cutting port, the blade rotates to cut the material into the desired size and shape. The cut material is output at the discharge port of the machine.

Web slitting machine daily should be how to carry out maintenance?
The slitting machine is an indispensable equipment in modern industrial production. In daily use, the proper maintenance of the slitting machine will be particularly important. Zhejiang Haosheng web slitting machine is widely used in cutting cardboard, coated paper, kraft paper, cultural paper, art paper, double-sided, packaging paper and other slitting machine daily maintenance is more important, because once there are some problems, it may affect the subsequent work of the slitting machine.
What are the direct causes of web slitting machine capacity?
The control of unwinding tension is very important to ensure the consistency of the slitting machine. During the unwinding process, the paper is transferred from the reel to the slitting machine by tension. Too much tension will cause the paper to stretch or break, while too little tension will cause the paper to loosen and slide unstable. Therefore, by controlling the unwinding tension to ensure its moderation and consistency, the paper can enter the slitting machine smoothly and increase the production capacity of the slitting machine.
Web slitting machine under what circumstances choose single or double knife?
The choice of single-blade or double-blade web slitting machine depends on the following: 1. According to the demand: the single-pole web slitting machine is suitable for small demand, and can only cut one paper tape at a time. The double-knife web slitting machine has two blades, which can cut two paper tapes at the same time, which is suitable for large demand and can improve production efficiency.
