The blow molding machine is a device for making plastic […]

The blow molding machine is a device for making plastic particles into hollow containers through a blow molding process. At present, there are two common types. One is a one-shot hollow extrusion blower using PP and PE, and the other is using PET. , PC or PP two-shot injection stretch blow molding two-step bottle blowing machine. The two-step bottle blowing machine is widely used in any shape of carbonated beverage bottles, mineral water bottles, cosmetic bottles, edible oil bottles, pesticide bottles, large-diameter bottles, high temperature resistant bottles and other packaging containers with crystalline plastics such as PET and PP as raw materials. . Many newcomers to the plastic bottle industry need to know and learn a lot before purchasing, and they need to purchase according to their own needs. The more expensive bottle blowing machine is naturally the better, but it is not necessarily suitable for you. Because there are many types of blow molding machines, they are generally divided into semi-automatic blow molding machines, manual plug-in automatic blow molding machines, and automatic blow molding machines. Taihui Machinery Co., Ltd. can be customized according to different output and bottle capacity of customers.

Now briefly talk about the two steps of the next two-step bottle blowing machine in production

1. Warm up

The preform is irradiated by an infrared high-temperature lamp tube, and the preform body is heated and softened. In order to maintain the shape of the preform, the preform mouth does not need to be heated, so a certain cooling device is needed to cool it.

Second, blow molding

At this stage, the preheated preforms are placed in the blow molding mold that has been made, the stretching rod is stretched down for high-pressure inflation, and the preforms are blown and drawn into the desired bottle shape.

Features of semi-automatic bottle blowing machine:

1. Blowing 0.1-5 liter PET bottles (one out of two), 5L-20L (single cavity)

2. Using two cavity molds to blow 500ml bottles, the output can reach 2000 per hour

3. Advanced PLC control system, time control can be accurate to 0.01 seconds

4. Special air storage device

5. Infrared lamp tube is used for heating, strong penetration, preform rotation and heating, orbital revolution, uniform heating, fast and reliable

6. Different heating lamps are equipped with independent temperature control devices to ensure that the preform has the ideal heating effect

7. The direction of the heating lamp can be adjusted according to different preforms

8. Only one person is needed for operation, no special training is required

9. Simple installation and startup

10. The scrap rate of finished products is less than 0.1%

The automatic blow molding machine does not need manual operation, and the output has different models of 2000-8000 bottles per hour.Features:

A. Using advanced microcomputer control system, stable performance;

B. The conveyor automatically sends blanks;

C. Infrared lamp tube is used for heating, strong penetration, preform rotation and heating, orbital revolution, uniform heating, 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. Every 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 an oil pump, 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 pressures for bottle blowing and action;

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

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, easy 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 0.1%
