What are the advantages of an inflatable shaft in general:
1) Wide application: inflatable shaft as an independently designed part, from 1 inch --- 12 inches, the length and size are determined by the actual needs of customers, where there are slitting printing, rewinding, coating, laminating, bag-making, papermaking and other work for equipment or other related center coiling machinery, can be applied to inflatable shaft.
2) Cost-effective: The design of the shaft is designed for the actual work needs, and it can be applied to various types of coils such as thickness, thinness, width and narrowness.
3) Long use time, simple maintenance: although the inflatable shaft is a mechanical accessory, every part in its own structure has a fixed specification, can be used interchangeably, so that it is easy to maintain.
4) Single accessory: The inflatable shaft is a single spare part of the winding and unwinding machinery, and each part in its structure has a fixed specification and size, which can be decomposed and combined, so that the maintenance is convenient and durable.
5) Professionalism: There are professional engineering and technical personnel for market research on the design, installation and use of inflatable shafts.
6) Large carrying capacity: the inflatable shaft can be designed according to the actual model, using high-quality steel to increase the carrying capacity. For example, steel materials can be used for bearing weight of more than 1 ton.
7) Short operation time: separating and placing the coil tube can be completed with only 2 seconds of inflation and deflation action, which is simple and convenient to place the coil, safe and applicable. All machines and equipment for winding and unwinding can be used for inflatable shafts. The length of the inflatable shaft can be up to six meters or more, and the shortest can be several hundred millimeters, all according to the customer's needs.
About the advantages of plate type inflatable shaft and precautions when using:
Advantages: the flatulence part is uniform, and the paper tube of various thicknesses can be basically applied; The expansion part is a plate, usually with a swelling height of 4mm to 5mm, which can be applied to machinery with high winding precision or lighter winding items, such as: electronic materials, battery materials, foam, plush, paper towels, non-woven fabrics, etc., which are mainly determined according to actual needs.
3 inch plate type inflatable shaft, usually using coil tube with an inner diameter of 76mm.
Note: If the length of the paper tube used for a long time is less than 1/2 of the length of the flatulence part, and the load is heavy, the two ends may be slightly upturned, which will affect the runout tolerance---;
The key inflatable shaft is divided into ordinary rubber key type and through-length key inflatable shaft, about the advantages of the key inflatable shaft and the precautions when using:
Advantages: the same size of the inflatable shaft, the weight of the key inflatable bearing is greater than that of the plate inflatable bearing; the key bar inflatable shaft: the expansion part is the key bar, usually the unilateral expansion height can reach 5mm to 6mm, can be applied to the mechanical winding load of heavy items, such as: cloth paper book film printing matter leather composite materials, etc., mainly according to the actual needs to determine.
Through-bar inflatable pumping: The expansion part of the through-bar inflatable shaft is a through-length key bar, which has the characteristics of high precision, high load-bearing and light weight.
Note: If the paper tube is relatively thin, and the key inflatable shaft is used in the same position for a long time to expand, the paper tube will be propped up and bulged or easily damaged.
air expanded shaft replacement airbag process:
1) Lift the key bar on the inflatable shaft, or remove the plate on the surface of the shaft;
2) Remove the shaft head with the air valve and remove the air bag in the shaft
3) Replace the airbag with a new one, and press both ends tightly, check whether the airbag sealing ring is in good condition, and replace it with a new one if the wear is serious;
4) Put the new airbag into the shaft and install the shaft head to fix it; Install the air valve and inflate it, and there is no air leakage.
Application of inflatable shaft in production machinery:
The use of inflatable shaft is very wide, and all machines with winding, unwinding and slitting can be applied to inflatable shafts, even including light metal industries. For example, the inflatable shaft is mainly suitable for printing equipment: drying machine, flexo printing machine, gravure machine, trademark printing machine, etc.; other machinery includes: coating machine, leather machine, setting machine, embossing machine, slitting machine, die-cutting machine, rewinding machine, paper tube machine, bag making machine, laminating machine, laminating machine, film blowing machine, foaming machine, laminating machine, embossing machine, paper machine, non-woven machine, cloth inspection machine, hot stamping machine, battery equipment and other related machinery supporting the use.
Ordering process for inflatable shafts:
1) Inflatable shafts (inflatable shafts) are generally made according to the needs of practical applications, there are no standard parts, and different types are selected according to different actual needs. The common types are aluminum alloy inflatable shaft, expansion key inflatable shaft and vane inflatable shaft, etc., and some distinguish between metal and non-metal.
2) The inflatable shaft is generally designed by the user and provided to the inflatable shaft manufacturer, and the customized requirements should be attached, such as the weight of the inflatable shaft, the material and its accuracy requirements. The manufacturer will conduct technical evaluation according to the drawings and other requirements provided by the user, and then carry out production.
3) As a special special equipment for winding and unwinding, the inflatable shaft is usually used with magnetic powder brake, magnetic particle clutch and tension controller.
