Heating device for blowing bottle preform with handle

Abstract

The invention discloses a heating device for blowing a bottle preform with a handle. A partition is arranged at the middle parts of opposite heating areas of a heating box and a heating air channel separately; the positions of the partitions are adjacent to the tail end of the handle on the bottle preform, and shield plates are arranged on the partition at one side of the heating box at intervalsin the movement direction of the bottle preform; and the shield plates and the handle on the bottle preform rotate to be opposite to positions facing the heating areas. The bottle preform continuouslyrotates around an axis while moving along the heating areas in a heating area, and the bottle preform is shielded by the shield plates while rotating to be opposite to a heating component on the heating box, so that heat emitted by a heating lamp pipe cannot be directly transferred onto the handle. The heating device is extremely simple in structure, the heating areas are skillfully partitioned to adapt to blowing for the bottle preform, the handle is protected, and then a container bottle with a handle is smoothly produced by virtue of a PET bottle blowing machine, so that the production difficulty for the a PET container bottle with a handle is effectively reduced, the machining quality for the container bottle is improved, and the production efficiency for the container bottle is increased.

Description

Technical field [0001] The invention relates to bottle blowing equipment, and in particular to a heating device for blowing bottle preforms with handles. Background technique [0002] Plastic container bottles are utensils that are often used in people's daily lives. They are generally blown from bottle preforms by a bottle blowing machine. Common container bottles can be divided into two types: with handles and without handles. Container bottles with handles are divided into two types. One is a bottle with a rear handle that is installed after the plastic bottle is blown. The other is a bottle with a handle. The first type is a bottle with a handle that is put into the handle during the blowing process and the two are blown into one. The former bottle is usually made of PET (polyethylene terephthalate) material, and the latter bottle It is made of HDPE (high density polyethylene) material. [0003] Bottle preforms with handles such as figure 1 As shown, both ends of the ...

AI Technical Summary

Problems solved by technology

However, the current PET blow molding machine lacks a proper method for cooling the handle, or the equipment used is extremely complicated, which has a great adverse effect on the installation and processing of the blow molding machine.
