The working principle of the bottle blowing machine and the characteristics of the automatic bottle

At present, most of the blow molding machines are still two-step blow molding machines, that is, plastic raw materials must be made into preforms before being blown. Nowadays, environmentally friendly PET materials are commonly used.

1. The principle of bottle blowing machine:

The blowing process of the blow molding machine is divided into two parts:

1. Preheating of bottle blowing machine:

The preform (embryo) is irradiated by an infrared high-temperature lamp to heat and soften the bad (embryo) part of the preform (embryo). Cooling device.



2. Blow molding machine:

At this stage, the preheated preforms (preforms) are placed in the blow molds that have been prepared, and high-pressure inflation is performed in them. Blow the preform (preform) into the desired bottle.

The automatic blow molding machine completes the two operations of the blow molding machine through the operation of the robot, eliminating the process of manually putting the preheated preform into the blow mold in the middle. Greatly speed up the production rate.



The characteristics and process of automatic blow molding machine: intelligent, reliable, efficient and energy-saving.

A. Using advanced microcomputer control system, stable performance;

B. The conveyor automatically sends blanks;

C. Infrared lamp tube is used for heating, with strong penetrating power, the preform rotates and heats automatically, the orbit revolves, the heating is uniform, fast and reliable;

D. The width and height of the lamp tube and reflector in the heating zone can be adjusted to suit the heating of preforms of different structures, and there is an automatic temperature exhaust device to ensure the constant temperature of the drying tunnel;

E. Each mechanical action has a safety self-locking device. When a process fails, the program will automatically switch to a safe state;



F. Each action is driven by the cylinder, no oil pump is used, which has the advantages of no pollution and low noise;

G. The air circuit design divides the action and blowing into three parts to meet the needs of different air pressure for bottle blowing and action;

H. High-pressure and double-curved-arm connecting rod are used for mold clamping, which has strong clamping force;

I. The operation methods are manual and fully automatic;

J. The safe and reliable unique valve position design makes the gas circuit clear;

K. The production process is fully automated, which has the advantages of low investment, high efficiency, convenient operation, simple maintenance and safety.

L. The bottle body is free from pollution

M. The cooling system achieves the ideal cooling effect

N. Simple installation and startup

O. The scrap rate of finished bottles is less than 0.2%

P. During the blow molding process: stretching-one blow-second blow, the time of the three actions is very short, but it must be well coordinated, especially the first two steps determine the overall distribution of the material, and the quality of the blow molding machine is good Bad. Therefore, it is necessary to adjust: the starting time of drawing, the drawing speed, the starting and ending time of pre-blowing, the pre-blowing pressure, the pre-blowing air flow, etc. If possible, it is best to control the overall temperature distribution of the preform The temperature gradient of the inner and outer walls of the billet.
