One-mold multiple-member full-automatic plastics stretch-blow machine

Abstract

A one-model multi-item automatic plastic stretching and blowing machine consists of a heating machine of a plastic bottle-pipe and a stretching and blowing machine. The heating machine is a main drive shaft which is arranged on a stander and is driven by power. A main drive chain wheel is arranged on the main drive shaft. A passive chain wheel which is arranged on a passive shaft is driven by the main drive shaft through a chain. A trusteeship is arranged on the chain. The trusteeship coordinates with the plastic bottle-pipe. The stretching and blowing machine comprises a template which is arranged in the stander, an opening and locking mechanism and a stretching and blowing mechanism. The present invention is characterized in that a bottle-pipe intermediate transmission device is arranged between the heating machine and the stretching and blowing machine. The bottle-pipe intermediate transmission device consists of a turning wheel and a driving belt which are arranged on an intermediate stander. A pipe clipping tongs is arranged on the driving belt. The pipe clipping tongs is contacted with a bottle-pipe. A plastic bottle-pipe sending device is arranged on one end of the heating machine. The pipe clipping tongs coordinates with the sending device which is arranged on the heating machine. The present invention is used for producing mineral water bottles, cosmetics bottles and so on.

Description

technical field [0001] The invention relates to a one-mould multi-piece automatic plastic drawing and blowing machine, which belongs to processing equipment of hollow plastic containers, for example, it can be used for processing mineral water bottles, medicine bottles, cosmetic bottles and the like. Background technique [0002] Using plastic raw materials (such as PET, etc.) to process hollow containers such as mineral water bottles, medicine bottles, cosmetic bottles, etc., firstly, the raw materials are injected into bottle tubes by an injection molding machine, and then the bottle tubes are heated by a heater and then stretched and blown by a stretch blower. , The heater that heats the bottle tube is combined with the stretch blow molding machine, and the bottle tube can be automatically transported, which is called a fully automatic plastic stretch blow machine. The automatic plastic stretch-blow machine has two types: single-station and multi-station. In the existing ...

AI Technical Summary

Problems solved by technology

There are two types of fully automatic plastic stretch blowing machines: single station and multi-station. The existing single station stretch blowing machine is to install the heater and the stretch blowing machine independently. The heated bottle tube is taken out of the heater by the robot and sent In the mold of the stretch blowing machine, the manipulator can only take and deliver one bottle tube at a time, so its disadvantage is that one mold can only process one workpiece (one plastic bottle for stretching and blowing), and the production efficiency is low
