Friction air shaft is generally divided into three categories of products, there are central pressure friction air shaft, side pressure friction air shaft, mechanical friction air shaft.
The mechanical friction air shaft was used more in the early days, but with the improvement of user requirements, the mechanical friction air shaft has been unable to meet the needs of customers, so at present, the mechanical friction air shaft is less and less seen on the market, replaced by the central pressure friction air shaft and the side pressure friction air shaft, especially the central pressure friction air shaft is more widely used.
At present, the central pressure friction air shaft on the market mainly has key friction air shaft, ball friction air shaft, etc., their structural principle is the same, dig three grooves on the shaft center, and then install the air bag felt, and finally install the slip ring to assemble a slip shaft.
In addition, the east extension slip axis and the West village slip axis are also central pressure friction air axes.
Roller (ball) friction air shaft:
1. Can be composed of central pressure type, pneumatic side pressure type, mechanical side pressure type high-performance slip shaft, the narrowest cutting coil material, large weight bearing, strong adaptability.
2. Slip shaft with easy loading ring.
3. Large axle diameter = high strength + low deviation shaft steel performance is very good.
4.3-inch main body outer diameter 75.5mm, axis 60mm, action diameter 77.8mm, suitable for paper tube inner diameter 76.2mm, standard width 25mm, can be customized according to customer requirements.
5. Mainly used in adhesive tape, protective film, optical film and other products with narrow cutting width requirements.
Key friction air shaft:
1. Key type friction air shaft with mechanical convex key to clamp the core, itself is air pressure, with the internal tension level, and then push each torque.The unit expands outward, and then sets the sliding torque value of each torque group according to the inflation pressure, which is convenient to adjust the slitting line and the time when each roll of material is rolled up
Tension, so that each slip ring can solve the phenomenon of unwinding, tightness and irregular end face caused by uneven material thickness and tension, so that it can be evenly rolled.
2. According to customer needs, evaluation and design manufacturing, production of special specifications and special tension, special surface treatment.
3. All kinds of special environment (dust-free, corrosive, high temperature environment) can be applied.
4. The main outer diameter of the slip shaft is 75.5mm, the shaft center is 50mm, the operation diameter is 77.8mm, which is suitable for the inner diameter of the paper tube is 76.2mm, and the standard width is 15mm,20mm,30mm, 37mm,50mm.
5. The slip shaft belongs to medium and low tension, has a wide range of applications and various widths, which can basically meet the needs of all customers.
Toshin friction air shaft:
1. Central pressure slip shaft, pneumatic locking, pneumatic slip. High precision, high performance, accurate torque, good tension control over a wide range.
2. Suitable for fully automatic loading and unloading of coil slip shaft, to ensure that the coil core is not shifted and not loose during positive and negative rotation.
3.3-inch main body outer diameter 75.5mm, action diameter 77.8mm, suitable for paper tube inner diameter 76.2mm, axis 50mm, standard width 50mm.
4. The friction air shaft is a large tension friction air shaft, which is mainly used in products with relatively large thickness such as sheets.
Nishimura friction air shaft:
1. Central pressure friction air shaft, pneumatic locking, pneumatic slip. High precision, high performance, accurate torque, precise control of tension over a wide range.
2. Suitable for fully automatic loading and unloading of coil slip shaft, to ensure that the coil core is not shifted and not loose during positive and negative rotation.
3. Suitable for short shaft use, when winding metal foil, copper foil, aluminum foil, it shows its excellent performance. Special form of West Village: can also achieve extremely low
Friction tension, applied to the thinnest (10U) pet film, electronic film slitting.
4. The main outer diameter of the slip shaft is 75.5mm, the shaft center is 45mm, the operation diameter is 77.8mm, which is suitable for the inner diameter of the standard paper tube is 76.2mm, and the width of the slip ring is 30mm, 40mm,45mm.
5. Nishimura friction air shaft is mainly used in the lithium battery industry of diaphragm, pole plate and other tension requirements are very low slitting and winding.
6. The Nishimur friction air shaft is divided into two types: single air slip shaft and double lines friction air shaft. One way of the double air slip shaft is to control the tightening of the paper tube, and the other way is to control and adjust the tension.
Nishimura friction air shaft piston commonly used specifications are: 8*14mm, 8*11mm, 8*8.5mm, 6*11mm, 10*8.5mm and so on.
Ximun friction air shaft expansion plate common specifications are: 19*19*6.5mm,19* 14*6.5mm,19* 12*6.5mm,19*10*6.5mm, etc., there are other less used specifications, you can consult us to confirm the stock purchase.
