Introduction of the components of the film blowing machine

Blow Membrane is a plastic processing method, which refers to a plastic processing

technology in which plastic particles are heated and melted and then blown into a

film. Usually, the polymer is extruded to form a tubular film blank, which flows in a

better melt flow. In the state, the tube film is blown to the required thickness by

high-pressure air, and it becomes a film after being cooled and shaped. The quality of

the film material blown by this process is related to the film blowing machine and

plastic particles. Film blowing machine is a machine that heats and blows plastic

particles into plastic film. The<a href="http://www.bogle-machine.com/film-blowing-

machine/" target="_self"> film blowing machine has the advantages of simple

structure, low investment, and quick product effect; high mechanical properties of the

film; no edge material and less waste; the film product is cylindrical and the bag-

making process is simple; it can produce a wide film.

The separation type screw divides the melting section into a solid bed and a

melt bed. The width and depth of the solid bed gradually become smaller, and the width

and depth of the melt bed gradually become larger, and finally become the width and

depth of the metering section.

1. Feed zone.The volume of the screw groove in the feeding section remains

unchanged. The material is in a solid state, and the main purpose is to transport the

material forward as soon as possible.

2. Melting zone. The volume of the screw groove in the compression section

gradually decreases. The material changes from solid to molten. The main purpose of

the material is to change from solid to molten.

3. Melt pumping zone.The volume of the screw groove in the metering section

remains unchanged. The material is completely in a molten state, and the main purpose

is to make the material fully plasticized and send the material to the machine head at

a fixed amount and pressure.

The cooling method of <a href="http://www.bogle-machine.com/film-blowing-

machine/pe-blown-film-machine.html" target="_self">PE Blown Film Machine can be

divided into two types: external cooling and internal cooling.

1. The external cooling method is the earliest application method.

Under the action of the cooling ring, cooling air is released from a circular ring

along the extrusion direction and the outer surface of the bubble to generate uniform

cooling air around the ring. Inside the cooling ring, the air at the upper port is

discharged at a faster average speed than that on the lower port. It is ensured that

the shape of the film bubble is consistent with that of the air cooling ring, so that

the average flow velocity of the air increases and thus the heat transfer is improved.

2. The internal cooling directly dissipates heat through the

film bubble for cooling purposes. Because the flow rate of the air in the bubble is

relatively low and has no regularity, external cooling is more widely used in the

market. In the blowing process of the film blowing machine, in order to ensure the

quality of the film product, the stability of the film bubble before the film is

formed must be considered in order to effectively control the product qualification

rate. The output of blown film of the film blowing machine is not only restricted by

the film bubble, but also the cooling system of the film blowing machine. A complete

cooling system can help the <a href="http://www.bogle-machine.com/film-blowing-

machine/pe-film-blowing-machine.html" target="_self">PE Film Blowing Machine work

and run rationally.

With the rapid development of industrial technology, the film blowing machine has

mastered the skilled production process, but compared with the more advanced

technology level in foreign countries, there are still some gaps in some aspects, in

order to obtain the development of the film blowing machine. In order to enter the

international market, we must let the film blowing machine develop in a new direction.

A special plastic wrap blown by the film blowing machine, using advanced

technology to make fruits and vegetables durable. The cling film is composed of a

transparent film of a nylon semi-packaging machine. The film is nearly transparent and

has good water permeability. A certain amount of sand syrup is placed in the

interlayer to gently wrap the surface of the article. The film must be environmentally

friendly. It is harmless and has strong water permeability. It can absorb fruit and

vegetable juice to achieve fresh-keeping purpose. This special raw material requires

high-end traction and drawing ability of the <a href="http://www.bogle-

film. Food packaging is the most used film. In the field, the high-grade film blown

out by the film blowing machine can be used as a commodity packaging promotion to

enhance commercial value.

At present, the popular packaging on the market is mainly plastic and paper. The

blow molding industry mainly based on plastic blown film machine has a large

proportion in the market, but with the stricter requirements on the paper industry,

the new environmental protection and energy saving The indicators have raised the

threshold for the paper industry, resulting in an increase in the cost of the paper

packaging market and rising prices. This has led to a corresponding increase in the

market share of plastic packaging, stimulating the development of the film blowing

machine manufacturing machinery industry, while environmental protection and energy

saving technology has been paid attention to in the film blowing machine machinery

industry, promoting the blown film machine to the high level.

In the future, as technology continues to deepen, the film blowing machine will

continue to be upgraded and will play a more important role in promoting the plastics

and packaging industry to the high end. China is a large manufacturing country with an

advantage in scale. However, in the research and development and commissioning of

high-end equipment, domestic plastic machines have not yet reached the international

level. Domestic blown film machine relies on huge consumer groups, and the market

prospect is promising, but the development towards high-end is the development trend

that blown film machines must face.

Film blowing machine blown out of the film is usually used for goods transport,

food packaging, product preservation, biotechnology and other industries, the quality

of film blowing machine and blowing

Film technology determines the quality of film forming. So a good performance of

the film blowing machine in the production of film process shows a good market

adaptation

Ability to improve production efficiency while providing convenience for people to

promote harmonious development of society.

Food packaging is the most widely used field of film, film blowing machine blown

out of the high-grade film can be used as a commodity packaging publicity, improve

commercial value. Today,

Film blowing machine development of high-end technology, film blowing can also be

used as a number of applications such as food preservation technology, take the road

of new film blowing machinery manufacturing. Blown film

Machine blown out of a special plastic wrap, the use of advanced technology, so

that fruits and vegetables long - lasting.

The plastic wrap is made up of a nylon translucent film, which is nearly

transparent and permeable, and is filled with a certain amount of sand syrup, gently
