The Inflatable Shaft Can Be Adjusted Online Without Stopping The Machine According To The User Model

The inflatable shaft is suitable for winding and unwinding reels, especially for the occasions where the paper tube has a high roundness requirement or the surface is used for winding and unwinding.

Plate inflatable shaft, three or four-piece inflatable shaft, tile inflatable shaft, but the working principle is the same, the user must specify the type of inflatable shaft, external dimensions, and mark the important dimensions on the shaft when ordering the inflatable shaft If there are special requirements, please indicate separately.

Features: Use aluminum alloy tiles, flexible expansion and contraction, equipped with high-quality rubber liner and quick filling and exhaust nozzles, good sealing effect, long service life, removable shaft head and convenient maintenance. After inflation, the expansion part is a plate, usually the expansion height can reach 4mm to 5mm (for example, the 3-inch diameter before expansion is 74mm to 75mm, and the diameter after expansion can reach 78mm to 79mm), special expansion height, additional requirements, 3 inch plate type Expansion shaft, usually using a roll tube with an inner diameter of 76mm.


Application: The plate-type inflatable shaft expands the entire plate, the fulcrum is evenly dispersed, and the force is even. It is suitable for winding precision machinery or winding lighter items, such as electronic materials, battery materials, Foamed cotton, plush, paper products, non-woven fabrics, etc., suitable for coating, slitting, printing, rewinding, laminating, paper making, bag making, plastics and other related machinery reels, especially suitable for paper tubes Where there is a higher roundness requirement or the use of surface winding and unwinding, it can effectively improve work efficiency and product quality.

The inflatable shaft is composed of two parts: an inflatable shaft and a long expansion tile. The size of the expansion torque is adjusted by the inflation pressure. Because the structure of the expansion is a long strip through the shaft, there is no section, so there is no slip function. There is no corresponding slip action for the tension changes due to material changes when slitting multiple strips, and it is easy to produce uneven winding, broken strips, loose winding, and unwinding phenomena, resulting in material loss. The winding speed is low. The air pressure adjustment should be stopped, which affects work efficiency. The unified shaft cannot simultaneously retract large and small rolls. Slitting machine is one of the relatively independent main equipment of machinery enterprises. The good and bad performance directly reflects the product grade and production efficiency. The torque force of the differential sleeve can be adjusted to achieve the required tension of each roll of material on the slitting line, so that relative sliding occurs between the differential sleeves, and its linear speed is automatically adjusted.

When adjusting the pressure, the machine must be stopped for adjustment, which will affect the work efficiency. The slip air shaft is composed of the air shaft and the slip sleeve. The inflatable shaft adopts central air pressure control. According to the user's model, it can be adjusted online without stopping, so that the piston on the shaft is ejected, each slip sleeve is braked to expand the sliding key outward, and the paper tube (plastic tube, nylon tube) Wait). The function of the winding shaft on the machine determines the performance of the slitting machine.
