ALUMINUM ROLLER

Aluminum guide roller (also known as "aluminum alloy guide roll") is made of high quality aluminum alloy materials, and it has all kinds of modules and sizes with ribs structure and the outside diameter is from 25mm to 320mm. Under the cheat by computer balancing correction process, the dynamic balance of the aluminum roller will be small than 2g. With using of sophisticated equipment and special tools, the roll surface gloss can be 0.8, concentricity can reach to 0.02mm. Special cheated in the shaft axle of the roller, with imported bearings, the aluminum guide roller works well even at high speed.
According to different industries, the surface of the roller can also do special treatment: Anodized HV300 treatment, Hard anodized HV700 treatment, Teflon treatment, to make the roller scratch, abrasion and anti-sticking.

AIR SHAFT

Air shaft is a special shaft for winding and unwinding. The shaft is created by the keys on the surface, which will be expand when the high-pressure gas filled in the shaft. Air shaft is easy to operate, the user only have the air supply with the air pressure controlled within 6-8kg/cm2. Just aired the shaft through the air valve and when user want to lock the web. Just push the core activities of the air valve to deflate, the keys will revert to its original appearance, then web can be removed easily.
Air shaft include key type (steel-made or ally-made) and lath type.
Air shaft is widely used for winding, rewinding and slitting machines. It is widely used in printing, packaging, plastics, paper, glass, pharmaceuticals, electronic battery, textile machine and industry.

CENTRIFUGAL BLOWER

DF series centrifugal fan can feature in rich wind, high pressure and low noise by the "multiple, forward, narrow" impellers. Widely used in printing, packaging, plastics, paper, glass, pharmaceuticals, footwear and other machiner and industrial. It can also be used for temperature, dust emission, cooling and so on.
Principle
Centrifugal fan consists of impeller, air inlet, spiral volute and other components. When impeller rotates, the air will leave the channel, the outward movement by the centrifugal force, the center of the impeller can generate the degree of vacuum, and therefore intake air. Then intake air will be folded 90at the entrance of impeller, get kinetic and pressure energy under the blades effect. Air flow from blade channel flows into spiral volute, exhausts from air outlet after concentration and deversion.
