The Size Of The Air Expanded Shaft Is Smaller, What Is The Most Convenient Solution

What is the most convenient way to compensate for the small size of the inflatable shaft? Of course, an core shaft adapter is the best way to compensate for it.

• Inflatable shaft: It is a special winding and unwinding shaft, that is, the shaft that can be inflated on the surface after high-pressure inflation, and the shaft that quickly retracts the surface part after deflation is called inflatable shaft, and its names are diversified, also known as pneumatic shaft, expansion shaft, flatulence shaft, inflatable roller, inflatable shaft, pressure shaft, etc., although there are many names, but the working principle is the same. Inflatable shaft, inflatable sleeve is very convenient to use, fast, only need the user to provide their own air source, air pressure control in the range of 6-8kg, when the reel core needs to be locked, as long as the inflatable handle is inflated on the air nozzle on the inflatable shaft can be completed, when the reel core needs to be loosened and discharged, press the sliding air core on the air nozzle by hand to release the air.
• Inflatable sleeve clamp: The inflatable sleeve is also called an inflatable sleeve, or an inflatable shaft expansion sleeve.

    Inflatable sleeve clamp: used to cooperate with 3-inch inflatable shaft (inflatable shaft with a diameter of 74 or 75) and 3-inch inflatable shaft sleeve      clamp, it can roll raw materials with larger diameter of paper tube, can replace 6-inch inflatable shaft, and can rewind and unwind larger diameter          items, which has higher usability.

The connection between the inflatable sleeve clamp and the inflatable shaft and the application field: the inflatable sleeve is suitable for coating, printing, rewinding, papermaking, plastic and other related machinery. Especially in the case of the frequent use of the three-inch and six-inch air shaft with light load, it shows its superiority, and the inflatable sleeve clamp can be moved and fixed in any position of the inflatable shaft. Installing two inflatable sleeves can replace the six-inch inflatable shaft, and the weight is light, and it is easy to load and unload.

The working principle of the inflatable drum of the inflatable sleeve clamp: inflate with the air nozzle with the air strength aligned with the shaft, the parts will have an effect, press the sliding gas release switch of the air nozzle, and the key bar will change back to its original appearance. And in normal work, the advantages of the air expansion sleeve are also very significant, one is the inflation period, the separation of the inflation nozzle and the gas strength equipment is rapid, which can ensure that the gas pressure change can be completed within three seconds. In addition, in terms of load capacity, these shafts can be regulated to a certain extent. According to the actual production load requirements, the size of the shaft diameter will be determined to a certain extent, and the material of the shaft itself can also withstand a certain degree of pressure and load.

Structural characteristics of inflatable sleeve: inflatable sleeve is mainly composed of front sleeve, rear sleeve, cylinder, inner tube, air bag, prominent keyboard and other parts. The expansion set is made of high-quality aluminum, with oxidized surface, high-quality airbags and fast inflators. Good sealing effect, long service life and easy maintenance.Advantages: light weight, easy loading and unloading.

Product specifications of air expandable shaft adaptor: It is divided into key inflatable sleeve and plate inflatable sleeve. Commonly used specifications are: 3 inches to 6 inches, 3 inches to 8 inches, 3 inches to 10 inches, 3 inches to 12 inches. After inflation, the diameter rises by 8mm. The length is 200mm, 250mm, 300mm, 400mm, 500mm, etc. (The length can be ordered according to customer needs, and the length is not limited)
Technical parameters of inflatable sleeve clamp: The outer diameter of the main body of the inflatable sleeve is Φ150mm, the outer diameter of the action is Φ155mm, and it is suitable for paper tubes Φ149-153mm, 201-205mm, 252-256mm, 302-305mm, and the main body length is 200mm, 250mm, 300mm, 400mm, 500mm, etc.

Advantages of air drum kit:
1. Short inflation operation time: the separation and placement of the inflatable shaft and the paper tube can be inflated and deflated in only 3 seconds, and there is no need to separate any parts on the end side of the shaft to tightly engage with the paper tube.
2. The paper tube is simple to place: with the action of inflation and deflation, the paper tube can be moved and fixed in any position on the shaft surface.
3. Large bearing weight: The size of the shaft diameter can be determined according to the actual needs of customers, and high hardness steel is used to increase the bearing weight
4. High economic efficiency: the design of the shaft is a special function, and it can be used in all kinds of thick, thin, wide and narrow paper tubes.
5. Simple maintenance and long use time: Although the inflatable shaft is a mechanical accessory, each part in its own structure has fixed specifications and can be used interchangeably, making it easy to maintain.

The electrical troubleshooting of the inflatable sleeve machine tool can generally be divided into the following steps:
(1) Preparation: Preparation includes the preparation of necessary tools, instruments, machine tool circuit diagrams and other materials
(2) Reading the diagram: For the machine tool to be overhauled, the circuit schematic diagram must be read first.
(3) Through "one question, two looks, three touches, four listens, and five operations", figure out the fault phenomenon and the situation before and after the failure.
One question: ask the machine tool operator to understand the situation before and after the failure; Did the failure occur suddenly or frequently? What anomalies are occurring? What is the anomaly? Wait a minute. In this way, accurately grasping the initial first-hand information is conducive to judging the location of the fault and quickly finding the fault point.
Second look: carefully observe the surface condition of the machine tool electrical appliances or wiring.
Three listening: start the machine tool, inflatable sleeve clamp, listen to the motor, control transformer, contactor, relay, etc. for abnormal sound and closing sound.
Four touches: when the inflatable sleeve clamps, after the machine tool runs for a period of time, cut off the power supply, use the hand mold to the shell or electromagnetic coil of the electrical appliance, and check whether there is more than ordinary heating phenomenon.
Five operation: from the start-up, all the functions of the machine tool are demonstrated one by one, and the operation process is carefully observed in the step-by-step operation, and the electrical fault of the machine tool is found from it, so as to quickly and accurately determine the range of electrical fault of the machine tool.
(4) According to the fault phenomenon combined with the circuit diagram to analyze the approximate range of the fault from the above process of "asking, seeing, listening, touching, operating" and other processes, the fault phenomenon can be basically clarified, then the general range of the fault can be analyzed in combination with the circuit diagram, and then the corresponding detection method is used to find out the fault point.
(5) Replace components: After the fault point is found, the inflatable sleeve components need to be replaced.

The main application areas of air expansion drums:

Analyze the selection method of inflatable sleeve clamp from the perspective of material and supplier:
1. Inflatable shaft inflatable sleeve clamp service life: The rubber inflatable sleeve clamp is wrapped with rubber, which is easy to wear, so the service life is relatively short, while the aluminum alloy inflatable sleeve clamp is used for a relatively long time.
2. The cost of inflatable shaft inflatable sleeve clamp: Some people may think that the cost of aluminum alloy inflatable sleeve clamp is higher than that of rubber inflatable sleeve, but in fact, there is not much difference between the two, basically the same. Therefore, when choosing an inflatable sleeve, our inflatable sleeve users can choose their favorite inflatable sleeve according to their actual needs or preferences.
