Product Description

Product Description

Demark Full-Automatic PET Bottle Rotary Stretch Blow Molding Machine

Blow molding machine is a machine that is essential for creating objects made of plastic. This machine uses a melting process to form the plastic to certain shapes through a mold. The molding process is quick, effective and allows for large-scale production of a wide range of products. The blow molding machine makes it possible to create objects in various shapes and sizes, from small, intricate pieces to large-scale plastic containers and tanks. The machine is fully automated and can handle high volumes of production. It ensures consistent quality and guarantees that each product meets specific standards.

Working Process

Working process as follows:
Put performs into hopper  →  Elevator send performs to arraying system  →   Array the preforms →  Perform loading  →  Preform heating  →  Robot put the heated performs into moulds Lock the moulds and start blowing   →  Finish blowing→   Robot takeout the bottles → Bottle outlet    

The electric control system can make control of automation,carrying out strict control in the process of elevating, arraying, loading, heating and blowing. Human interface achieves central control.

Working principle of blow molding machine:
Main wheel of equipment rotates in high speed. The encoder at the top of equipment and sensors installed on the main wheel test the angle of rotation and give computer feedback. Then in accordance with the operator of the procedures it set (angle) issued directives to executing agency(electromagnetic valve). The implementation process of blowing on a specific time, resulting to complete the process of a two step blowing and produce qualified products in rotating equipment.

Internal Structure

Technical Advantages

1. Automatic feeding device

Preform will be feeded and listed automatically.The device can adjust the preform quantity according to productivity, start and stop feeding automatically. To maintain uninterrupted feeding and not aggregate.It can adjust its output speed according to different preform type, so that preform feeding quantity coincide with production.
 

2. Heating machine

There are specially designed ventilation cooling devices and protective plate cooling water cooling in heating machine.Protecting the protection board and external when the temperature is too high. Thermal wind is controlled by frequency adjustable fan. Make sure the preform neck will not distorted by heating and increase the penetration, extend the life of infrared lamp at the same time.
 

3. Special mould plate system

Specially designed mould plate system make ensure that the replacement of the mould can be do quickly, accurately and good interoperability. Mould plate has pressure balance device. When blowing the bottle, it can make minimum of spew line, ensure the quality and performance of bottle. Special designed seal make low pressure when preform mouth connected with sealing mouth, and will not damage preform mouth.
 

4. Robot Device

Unlike the old mechanical gripper, the new one does not have a long spring. The use of double groove blank bottle pick-up and delivery cams, optimised robot structure, increased process angle, good synchronisation and coordination, good repeatability of movements, more flexible bottle blowing and lower losses.

Technical Features

1. Air compressor without oil: supply needed working pressure in the normal working(0.8Mpa) and high pressure for completing high pressure blowing.
2. Water chiller: The cooling system consist of cooling tower supplies cooling effect for air compressor without oil, blowing machine, hot water chiller and temperature control(oil).If the bottle is for water or carbonated, the cooling tower supply cooling water for buttom bottle mould and bottle mould; It needs hot water machine and temperature control(oil) if it is hot-filling bottle.
 

3. Hot water machine: the function is supplying steady hot water for buttom of mould, make the buttom of mould have steady temperature, ensure the blowing temperature.
4. Temperature control: the function is mainly provide a stable temperature for bottle body mould, make crystal of bottle material, meet the hot-filling requirements for bottle distortion. Heating media used in temperature control is industrial heat conductivity oil.
 

With blow molding machine, manufacturers can produce a range of products, including bottles, jars, containers, drums, and tanks, which can be used in various industries such as food and beverage, packaging, healthcare, and cosmetics. It is a cost-effective way to mass-produce products and has become increasingly popular with manufacturers worldwide.

Overall, the blow molding machine is a reliable, efficient and versatile machine that is widely used in the manufacturing industry for producing high-quality plastic products. Its ability to produce complex shapes and sizes makes it an essential piece of equipment for any production line looking to create a line of durable and high-quality products.
