Linear conveying type full-automatic plastic bottle blowing machine

Abstract

The invention provides a linear conveying type full-automatic plastic bottle blowing machine. The linear conveying type full-automatic plastic bottle blowing machine comprises a heater and a stretching-blowing machine, wherein the stretching-blowing machine comprises a mold locking rack on which a mold locking device is arranged; a mold is placed in the mold locking device; a stretching mechanism is arranged on the mold; a bottle conveying manipulator is arranged on the stretching-blowing machine; a blank feeding mechanism is arranged on an inlet of the heater, and while a blank conveying mechanism is arranged on an outlet of the heater; the heater comprises a heater support; a heating driving wheel, a heating driven wheel, a heating light box and a running orbit are arranged on the heater support; conveying chains on which bottle brackets are placed are arranged on the heating driving wheel and the heating driven wheel; the bottle brackets are in match with plastic bottle blanks; and overturning cams are arranged on the conveying chains. According to the scheme of the linear conveying type full-automatic plastic bottle blowing machine, the bottle brackets can be automatically overturned, and the blank conveying mechanism can be used for conveying the blanks and determining the distance, so that the utilization rate of the heater is increased, and the energy consumption is reduced; and the linear conveying type full-automatic plastic bottle blowing machine is simple in structure and easy to process, and the cost is saved.

Description

technical field [0001] The invention relates to a linear conveying type full-automatic plastic bottle blowing machine, which belongs to the field of plastic machinery. Background technique [0002] Using plastic raw materials to process hollow plastic containers, such as mineral water bottles, oil bottles, etc., first use the injection molding machine to inject the plastic raw materials into preforms, and then heat the preforms through the heater twice, and then blow the heated preforms by stretch blowing machine forming. Combining the heater and the stretch blowing machine together is called a fully automatic plastic blow molding machine. There are many types of automatic plastic blow molding machines, one of which is that the heater and the stretch blow machine share the same chain running track, which is fully automatic. Linear plastic blow molding machine mainly includes preform loading mechanism, preform heating and conveying mechanism, stretching and blowing mechanism...

AI Technical Summary

Problems solved by technology

The preform loading mechanism in the prior art generally adopts the gripping structure of the manipulator. The manipulator needs to complete the actions of forward and backward displacement, up and down lifting, and rotation. , low production efficiency

On the other hand, the distance between the heating seats (bottle holders) on the chain is determined by the size of the container (bottle) after stretching and blowing, so the distance between the preforms during heating is large, and the utilization rate of the heater is low, especially for large-capacity production. For bottles, the distance between the heating seats is larger, the heat utilization rate of the heater is lower, and the energy consumption of the machine is increased
