Problems solved by technology
[0004] Due to the high temperature of the preform gate and lifting ring after welding, the welding part between the preform gate and the lifting ring is relatively soft. Waiting for the temperature of the welding part to drop will not only affect the efficiency of the blowing bottle, but more seriously will cause the preform to break. Lowering the temperature will affect the quality of the subsequent bottle blowing process; maintaining the high temperature of the preform and reducing the temperature of the welding part become a pair of contradictions; how to ensure the quality of the plastic bottle produced by the blow molding machine without reducing the production efficiency is the concern of those skilled in the art major technical issues

Embodiment Construction
[0024] The present invention will be described more fully below using examples. This invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein.
[0025] For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature relative to another element or feature shown in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientatio...

The invention discloses a bottle blowing machine. The bottle blowing machine comprises blank conveying fingers and a bottle blowing mechanism. The bottle blowing mechanism comprises sealing openings, a side mold, a bottom mold, drawing rods and blank conveying finger position sensors. The drawing rods are located in the sealing openings and internally provided with outlets for compressed air for bottle blowing. According to the bottle blowing machine, the position sensors are additionally arranged, the positions of bottle blanks are determined in time, the drawing rods can rapidly stretch into the molds, the positions of sprues of the bottle blanks are corrected, and bottle walls are supported. The relative positions of the upper parts and the lower parts of bottle bodies are kept fixed, deformation of the bottle bodies is avoided, and the pass percent of the plastic bottles is increased.
Description
technical field [0001] The invention relates to a bottle blowing machine and a bottle blowing method. Background technique [0002] Plastic bottles are widely used because of their simple production and low cost. Its production method mainly relies on preheating two-way stretch blow molding machine (hereinafter referred to as blow molding machine) blow molding. There is a sprue at the bottom of the semi-finished plastic bottle during the molding process, and the sprue is used for welding the lifting ring. The plastic bottle forming and sprue welding rings are all formed by the blow molding machine at one time. [0003] The bottle blowing machine consists of three parts: preform feeding mechanism, heating system and mold clamping mechanism; plastic bottle forming is mainly in the mold clamping mechanism. The gate of the preform and the lifting ring are welded on the upper embryo section and the heating section and enter the mold clamping section; the action steps of the mo...
