Machine structure
Automatic preform unscrambler
1) Base taking, base feeding, bottle taking and bottle arranging fully are automatically completed with manipulator for avoiding middle pollution.
2) The design of the recycling unit prevents the preforms from getting bound up in the unscrambler.
3) The star wheel design of the feeding unit provides the lowest possible changeover times for switching to different perform sizes.
Linear heating oven
1) A mandrel capable of turning 180 degrees guarantees uniform neck section during the heating. A unique oven ventilation system enables the blowing system to handle various difficult applications easily.
2) Water cooling plate: cooling bottle neck, avoid neck deformation during heating.
3) Infrared heat lamps:
i). Each lamp is individually adjustable;
ii). Lamp gripper is adjustable as angle changes;
iii). Lamp rod is adjustable in length, which is good for bottom heating;
Advantage of rotary automatic stretch-blow molding machine
1)With SIMENS PLC controlling system to ensure high precision and fast speed;
2) High eligible rate: above 99.7%;
3) Molds and Mold Carriers
The mold carrier with a shell blow mold design; this reduces the changeover time for different blow molds. The Mold carriers accommodate all shell type molds from conventional blow molding machines, this saves time and expense for bottle producer. Moreover, the reliable quick locking system maximizes the performance of the mold carriers.
1) Blowing Station
A changeable cam for the stretching curve guider guarantees the form quality for different bottle size. Monobloc blowing valves achieve the fastest and most consistent blowing process possible. Bottle necks are protected during blowing stage by a specially designed sealing unit.
