Item	Details
Product Name	Mulch Wind Ring
Purpose	Mainly applied to blown film production equipment, it is responsible for precisely controlling the thickness and folding diameter of the film during the production process of mulch, ensuring the uniform and stable quality of the mulch.
Working Principle	A stable air flow is delivered by a blower. The air flow circulates through the annular channel inside the wind ring and is evenly ejected from the air outlet, acting on the freshly extruded molten plastic film, quickly cooling and shaping it, and adjusting the film width according to the air flow direction designed by the wind ring.
Material	– Main Body: Usually made of high-quality aluminum alloy, which is lightweight, easy to install and adjust, and also has good thermal conductivity, facilitating heat dissipation and preventing local overheating. – Air Outlet Parts: Some are made of stainless steel, which is wear-resistant and corrosion-resistant, able to withstand the impact of high-speed air flow for a long time and maintain the shape of the air outlet and the stability of the air flow.
Size Specification	The inner diameter of the wind ring commonly ranges from 200 to 800 mm, matching the discharge ports of different specifications of blown film machines; the height is approximately 150 – 400 mm, and the overall compact design does not take up too much space.
Wind Ring Types	– Single-Air-Outlet Wind Ring: It has a relatively simple structure. The air flow blows out from a single annular air outlet, with a lower cost, suitable for small blown film equipment or production scenarios with low requirements for film precision. – Double-Air-Outlet Wind Ring: It has inner and outer two-layer annular air outlets, which can output air flows with different velocities and temperatures, enabling more precise control of film thickness and width, and is often used in medium-to-high-end mulch production.
Wind Speed Adjustment Range	The minimum wind speed can reach 5 – 10 m/s, which is used to initially stabilize the film; the maximum wind speed can reach 30 – 50 m/s, and the high-speed air flow helps the film to cool quickly and form precisely.
Air Volume Adjustment Method	– Manual Adjustment: By means of the air volume adjustment valves on the wind ring, the operator manually rotates the valve knobs to intuitively change the ventilation area, thus regulating the air volume. – Automatic Adjustment: Paired with an intelligent control system, sensors monitor parameters such as film thickness and temperature, send feedback signals to the controller, and automatically and precisely adjust the air volume.
Temperature Control Association	Although it does not have a heating function itself, the temperature of the air flow blown out by the wind ring indirectly affects the cooling speed and crystallization state of the film. Some high-end wind rings can be linked with the temperature control system to ensure the constant temperature of the blown air flow and maintain the stable quality of film formation.
Installation Method	Flange connection is adopted. The flange plate at one end of the wind ring is accurately aligned with the corresponding flange of the discharge port of the blown film machine and fastened with bolts. It is convenient and firm to install and easy to disassemble for maintenance.
Auxiliary Equipment	It often works in cooperation with blown film machines, tractor units, and winding machines. The wind ring shapes the film with the blown air flow, the tractor unit continuously pulls the film forward, and the winding machine finally winds the formed film neatly.
Precision Control	It can control the thickness error of the mulch within the range of ±0.01 – ±0.03 mm, and the folding diameter error within the range of ±5 – ±10 mm, ensuring that the product meets the standards for agricultural planting use.
Maintenance Points	Regularly clean the internal air ducts of the wind ring to prevent the accumulation of dust and plastic debris from affecting the air flow; check the wear condition of the air outlets and replace the parts in time if there is any damage; lubricate and maintain the moving parts such as adjustment valves to ensure smooth adjustment.
Applicable Film Materials	Mainly applicable to the production of mulch made of common plastic materials such as polyethylene (PE) and polyvinyl chloride (PVC). Due to the characteristic differences of different materials, the corresponding adjustment parameters of the wind ring are also different.
Packaging Form	Wrap the whole wind ring with plastic film first, and then put it into a wooden or iron packing box. Fill the box with foam cushioning materials to prevent collision damage during transportation.
Minimum Order Quantity	For standard models, it is usually 1 – 2 pieces for minimum order; for customized models, the minimum order quantity may be adjusted to 3 – 5 pieces according to the complexity of customization.
Price Range	The price of ordinary single-air-outlet wind rings is between 500 – 2000 yuan; the price of double-air-outlet wind rings and wind rings with automatic adjustment functions is between 3000 – 8000 yuan. The price of customized products is negotiated according to requirements.
Warranty Period	12 – 18 months from delivery. During the warranty period, non-human-damaged parts will be repaired or replaced free of charge.
Supporting Services	– Installation Guidance: Provide detailed graphic or video tutorials. If necessary, technical personnel can provide remote assistance or even on-site installation. – Operation Training: Conduct online and offline courses for operators, explaining equipment operation, parameter adjustment, and daily maintenance knowledge. – After-sales Maintenance: Set up an after-sales hotline to respond to after-sales requests within 24 hours and solve equipment failures in time.

Product features:

Precise cooling control:

It can carry out fine air cooling treatment on the plastic film melt extruded from the die, precisely adjust the wind speed and air volume of the cooling air, and make the plastic film cool down quickly and evenly, which helps to stabilize the thickness of the plastic film forming, avoid the thickness deviation caused by local overheating, and ensure the stability of product quality.

Uniform and stable wind field:

The unique structural design makes the blown wind form a stable and balanced wind field, without the dead angle of obvious uneven wind strength. In the circumferential direction of the plastic film, all parts can obtain equal cooling to prevent the problems of film bubble wrinkles and uneven surface due to uneven cooling, and ensure the smooth appearance of the plastic film.

Strong adaptability:

It can match the production of mulch film of different specifications and materials, whether it is commonly used polyethylene (PE) mulch film or functional mulch film with special needs, it can flexibly adjust the air ring parameters to achieve effective cooling, showing good versatility.

Energy saving and high efficiency:

With the help of optimized air duct and fan blade design, the ideal cooling effect is achieved while reducing the energy consumption of the fan as much as possible. Compared with the traditional air ring, it can maintain a stable and efficient cooling operation with lower power input, which meets the long-term and large-scale production needs. Compact structure: The overall structure layout is reasonable and compact, takes up less space, and is easy to install. It is easy to quickly integrate with other equipment in the film production line. During subsequent maintenance, key components are also easy to disassemble, check and replace, reducing the difficulty and cost of operation and maintenance. Durable material: Choose high-quality metal materials that are resistant to corrosion and high temperature, which can withstand high temperature and plastic additives in the production environment, maintain stable performance for a long time, and have a long service life, reducing production interruption and cost increase caused by frequent replacement of equipment.

Application:

The plastic film air ring is mainly used in the blown film production process of the plastic film. During production, the film bubbles extruded and blown from the die are in a molten state, and the high-speed annular air flow blown by the air ring can quickly cool and shape them. This can effectively prevent the film bubbles from falling or sticking during winding, ensuring the smooth progress of production. At the same time, the air ring adjusts the air volume of different parts of the trend, so that each part of the film bubble cools evenly, which helps to control the thickness of the film, improve the mechanical properties and optical properties of the film, so as to ensure the quality of the film, and meet the needs of different types and specifications of film in agricultural production.
