Full Automatic SPET-2L-6E Pet Bottle Jars Making Stretch Blow Molding Machine

The characteristics of 6 Cavities Full AUTO PET Automatic Blow Moulding Machine


High speed and high output: 

The drying tunnel and bottle-blowing process are separated, which speeds up the bottle-blowing speed and improves the overall production. The output can reach more than 12,000 bottles per hour, greatly meeting production needs.


Compact design and space-saving: 

Usually a compact appearance design is adopted, saving production space and reducing investment costs.


High degree of automation: 

Equipped with an automatic conveying system, it realizes the full-process automated production from raw materials to finished products, reduces manual intervention, and improves production efficiency and product consistency;

Adopting an advanced PLC control system, the control panel is light and simple, easy to operate, and easy to master

The unique heating system can accurately control the temperature, ensure that the preform is heated evenly during the heating process, and improve the quality of bottle blowing;

Every action of the Pet Bottle Blow Moulding Machine is driven by a cylinder, not an oil pump. This design reduces pollution and improves the environmental protection of the equipment.


A variety of molds are available: 

The Pet water Bottles making machine can use different molds to produce different types of bottles, which improves the flexibility and maneuverability of the production line.


Stable operation: 

Sinotech Machinery Co., Ltd.'s high-quality PET bottle-blowing machine has more than 20 years of stable operation experience.


High-cost performance: 

Sinotech Machinery's Pet Bottle making machine not only provides efficient production but also has a high-cost performance, allowing enterprises to control costs while increasing production.


Appliance

Wide application: PET bottles are not limited to liquids, but also semi-solids, and are widely used in medicine, food, beverages, cosmetics and other industries.

Detailed Description

Preform conveying structure

The unheated preform (PET raw material) is conveyed to the heating area to ensure that the preform will not be inverted during the heating process, thereby ensuring the smooth progress of the subsequent bottle-blowing process.


Heating system

The infrared lamp penetrates the preform for heating, making the preform stretch more evenly and highly transparent. The heating system is also equipped with an intelligent temperature tracking system, which can fully keep the temperature in the heating box constant and avoid the problem of manual intervention in temperature adjustment due to the large temperature difference between morning and evening. The imported reflective mirror aluminum plate is installed inside to make full use of the heat energy of the lamp, shorten the heating time, reduce energy consumption, and increase production capacity. The temperature of each lamp in each layer can be adjusted separately to meet the heating requirements of different preforms.


Mold closing and clamping structure

After the preform is heated, the mold closing system merges the mold and the bottom mold to provide a stable molding space for the bottle-blowing process. Stable, noiseless, and high-speed operation.


Stretching and bottle blowing system

The stretching system longitudinally stretches the heated preform, and the bottle-blowing system blows the preform through high-pressure gas. The two-stage stretching technology driven by the servo motor saves stretching time in the first stage and achieves high-speed stretching in the second stage, which reduces the eccentricity of the center point of the bottle bottom and improves the quality of bottle blowing.


Cooling system

When the preform is heated, the cooling water channel is used to block the heat of the lamp tube, and a cold air system is set at the bottle mouth to cool the bottle mouth and protect it from deformation.


Control system

The PLC (programmable logic controller) control system is adopted, combined with a Chinese and English color touch screen for operation. It has a high degree of intelligence, simple and convenient operation, and can always control the production status of the equipment.


Manipulator and auxiliary equipment

The simple and reliable manipulator design transports the preform to the bottle-blowing machine base, transfers the finished bottle to the bottle-down station, and the entire production line is automated.
