DEVICE AND METHOD FOR IMPROVING COOLING PRODUCTION EFFICIENCY OF CRYSTALLIZER BOTTLE MOUTH

摘要

The present invention discloses an apparatus and a method for improving the production efficiency of crystallizer bottleneck cooling, the apparatus includes a cooling turntable, a plurality of cooling head assemblies, a cam plate of preform insertion, a cam plate of preform lifting and a cam plate of preform release, a protective sleeve is provided on the crystallization chain, and the preform is set in the protective sleeve with the preform neck exposed at the protective sleeve, the cooling head assemblies are mounted on the cooling turntable and set at the top of the protective sleeve. The cooling head assembly includes a upper mounting plate and a lower mounting plate, a cooling shaft body, a guide shaft. The upper mounting plate is provide with a upper roller, the lower mounting plate is provide with a lower roller. The cam plate of preform insertion, cam plate of preform lifting and cam plate of preform release are mounted on the rotating path of the cooling head assembly. The cam plate of preform release is set at downstream of the cam plate of preform lifting, and the cam plate of preform insertion lies above the upper roller, the cam plate of preform lifting lies below the lower roller, the cam plate of preform release lies between the upper roller and the lower roller. It can improve the production efficiency of crystallizer bottleneck cooling.
