Automatic production line for blow molding of plastic bottles

Abstract

According to the plastic bottle blow molding automatic production line provided by the invention, the constant-temperature preheating module, the variable-pitch transfer module, the bottle blowing module and the finished product transfer module are linearly arranged to form a linear bottle blowing production line, and the blank supply module is arranged on the side part of the linear bottle blowing production line; the blank supplying module is arranged above the feeding end of the constant-temperature preheating module in a matched mode, the overturning blank conveying module is arranged above the feeding end of the constant-temperature preheating module in a matched mode, and the blank supplying module and the overturning blank conveying module are matched to continuously overturn and supply bottle blanks to the constant-temperature preheating module; the whole production line is reasonable and compact in layout, all working procedures are efficiently matched, the production efficiency is greatly improved, the bottle blowing quality is guaranteed, and the full-automatic production line is particularly suitable for full-automatic production of large-capacity plastic bottles made of special materials.

Description

technical field [0001] The invention relates to the technical field of bottle blowing machines, in particular to an automatic plastic bottle blow molding production line. Background technique [0002] The blow molding machine is a kind of equipment that makes plastic particles, plastic preforms, etc. Two-time forming stretch blow molding machine, and the newly developed multi-layer hollow extrusion blow molding and stretch blow molding. The bottle blowing machine generally includes a frame and a heating structure, a spacing structure, a conveying structure, a blowing structure and a mold clamping structure arranged on the frame. During processing, the heating structure heats and softens the preforms, and the separation structure receives the heated and softened preforms and divides them to the distance matching the mold cavities in the clamping structure, and the conveying structure inputs the softened preforms into the clamping structure , The bottle blowing structure blo...

AI Technical Summary

Problems solved by technology

[0004] However, for large-capacity pp bottles, due to their good fluidity and sensitivity to temperature, they have high requirements for the preform heating process. The preform heating structure in the existing technical scheme is difficult to control the uniform heating inside and outside the preform. In addition, the bottle The billet is usually preheated in an inverted state, and the existing technology cannot adapt to the continuous feeding speed to realize continuous flipping and feeding, which reduces production efficiency

Therefore, there is still a lack of fully automatic blow molding production lines for bottles of special materials and specifications
