Three drum single stage tire building machine

Three drum single stage tire building machine feeding by the host, the carcass frame, the belt layer feed rack tread feeding frame, crowned strips for rack and electric control system.

1, host: host, including the base, the two main chassis, two spindle, the three drum (carcass molding shares, stereotypes shares, the belt layer to fit drums) and two with slide transfer ring.
Carcass feed rack: the carcass feeding rack by lining layer feed rack, tire side feeding rack and two carcass ply feed rack.
3, the belt layer feed frame: The feed frame, including the upper and lower feed frame, a belt layer laminated on the way.
4, the tread feeding rack: tread after opening by the common motor guide, using mechanical centering means fixed in order to improve the fixed-length accuracy, the use of a servo motor as a fixed-length drive automatically, cutter using ultrasonic cutter .
5 crown the fetal strips for rack: crowned bar guide to open by a common motor control, cloth storage, flip import a wound head wound pomade cylinder drive along the belt layer fitting drum radial crown tire strips sent to the belt layer bonded drum, by the winding head of the press roll nip.
