A pet bottle embryo energy saving and conveying process and system

Abstract

The invention relates to an energy-saving and conveying process for PET bottle preforms. The transport plate extends into the injection molding machine, and the injection molding machine arranges several preforms that are injection-molded on the transport plate; S3, the transport mechanism quickly sends the transport plate to the blow molding machine; S4, the transport plate introduces the preforms with residual temperature into the blow molding machine In the bottle machine; a preform injection end conveying system, including an injection molding machine, a transport mechanism, a transport plate and a bottle blowing machine. In order to neatly hold the preforms injected by the injection molding machine, the transport mechanism is used to drive the transport plate to reciprocate between the injection molding machine and the blow molding machine to realize the transportation of the injection molded preforms. The invention integrates the injection-molded preforms, which is simple, fast and pollution-free, and sends the preforms to blow molding, and maximizes the use of the residual heat of the injection-molded preforms to save the energy consumption of heating the preforms before blowing.

Description

technical field [0001] The present invention relates to injection molding technology, in particular to a PET bottle preform energy saving and conveying process and system. Background technique [0002] At present, most of the blow molding machines are still two-step blow molding machines, that is, the plastic raw materials must be made into preforms and then blown. In the process of preform blowing, the preform is heated first, and then the preform is put into the cavity of the forming mold, and then the stretching rod of the stretching group above the forming mold is stretched into the preform, and the compressed gas is injected from the inside of the stretching rod. The blowing channel is blown into the preform for blowing. In addition, most of the injection molded preforms and blown bottles are divided and cooperated by different manufacturers. This production method makes the preforms need to be transported to the blow molding factory for blowing after injection molding...

AI Technical Summary

Problems solved by technology

Moreover, most of the injection molded preforms and blown bottles are divided and cooperated by different manufacturers. Such a production method makes the preforms need to be transported to the bottle blowing factory for blowing after injection molding. The whole process requires a waste of manpower and material resources for transportation. The injection molded preforms have a certain residual temperature. However, after transportation, the preforms will be cooled. When they arrive at the blowing factory, the preforms need to be reheated. Generally, the common blowing machines use super-long heating systems. To heat the preform to meet the material elasticity requirements, and then blow the bottle, which takes a long time, occupies a large area, consumes a lot of energy, has low production efficiency and high cost, and obviously wastes the waste heat of the preform that has just been injected, which is different from the current national Contrary to the energy saving and emission reduction advocated, the economic benefit is small
