China Air knife's application Manufacturers, Suppliers, Factory

In production, drying generally adopts brush drying combination or hot oven drying type, brush bottle device is mainly used to remove water droplets on the bottle wall by rotating brush. As a result of the use of contact treatment, brush bottle effect and bottle shape has a close relationship.

Air knife is actually high pressure fan air into the air knife, with a thickness of only 0.05 mm airflow sheet high speed blow out. Thanks to the Coanda effect principle and the special geometry of the air knife, this thin wind curtain can be up to 30 ~ 40 times the ambient air, creating a thin, high-strength, atmospheric-current impact wind curtain. Air knife from the working mode is divided into two categories: standard air knife and super air knife, standard air knife wind curtain deflection 90 degrees after blowing, super air knife wind curtain horizontal blowing out.

The key to the production of plastic thermoforming sheet by casting method is to make the sheet closely adhere to the roller. Otherwise, the surface of the sheet will be uneven, the transparency will be reduced, and the secondary processing performance will be deteriorated, which will affect the quality of the final plastic thermoforming product. Therefore, the general equipment is equipped with an air knife, which blows out a certain air pressure and temperature from the air knife slit nozzle, so that the sheet is close to the roller. Some of the air supply methods use a blower, some come from an air compressor. Therefore, some People also call "air knife" "air knife".

Air Knife Systems are suitable for a range of applications for heavy industry, including removal of metal, wood, dust, powder, oil debris from objects, surface preparation for pre-and post-paint work, and removal of static. They are available in a range of sizes and types, can be added on to existing production lines easily, and can be fully or partially enclosed to minimise contamination and noise as needed.

The air knife is a very delicate tool, especially the lip part. Although it is made of aluminum alloy/stainless steel, it is very easy to be deformed by collision, so it must be carefully cared for. When the air knife is replaced by the sinking roller during shutdown, the lip of the air knife must be covered with the air knife cover first. When the steel belt tension is opened, the fan is turned on first, and then the knife cover is removed to prevent the steel belt from scratching the air knife lip. Tools made of copper sheets must be used to clean the air knife. If there is sticky residue on the upper or lower part of the air knife lip, it must also be scraped with a softer tool to avoid damaging the air knife.

Air knife is one of the basic accessories that ensure the function and efficiency of drying and water removal of production equipment. The application of air knife is distributed in a wide range of industries. The air knife can produce a strong wind force, used for various air knife blowing applications, so what industries does the wind knife have?
