Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Reference Figure 1-6 A hot air blowing type felting device with two sets of air knives includes a fabric frame 1, which serves as a basic support. A felting box 3 is installed on the fabric frame 1. One side of the felting box 3 is set as the fabric inlet side, and the other side is set as the fabric outlet side. A fabric inlet roller is installed on the fabric frame 1 on the fabric inlet side to smoothly and orderly introduce the felt to be felted into the felting box 3. A fabric outlet roller is installed on the fabric outlet side of the fabric frame 1 to draw the felted fabric out of the felting box 3, ensuring smooth conveying of the felt throughout the entire processing.

[0016] Inside the fulling box 3, from the fabric inlet side to the fabric outlet side, are sequentially installed a guide roller 9.2, a first support roller 4, and a second support roller 5 for cooperating with the felt. The guide roller 9.2 guides the felt into the fulling box 3 and initially adjusts its direction, allowing the felt to move within the box along a predetermined path. The first support roller 4 and the second support roller 5 provide stable support for the felt, ensuring it remains flat during hot air blowing and fulling treatment, preventing wrinkles or deviation. Preferably, the first support roller 4 and the second support roller 5 are arranged vertically side by side, with the second support roller 5 positioned directly above the first support roller 4.

[0017] A first air knife component 6 is installed in the fulling box 3 at the first support roller 4 to cooperate with the first support roller 4, and a second air knife component 7 is installed in the fulling box 3 at the second support roller 5 to cooperate with the second support roller 5. The first air knife component 6 is used to use the sprayed hot air to initially blow the fleece fabric that has just entered the fulling area and has not yet fully unfolded, making the fleece fabric surface more fluffy and preparing it for subsequent fulling treatment; the second air knife component 7 is used to use the sprayed hot air to directly act on the surface of the fleece fabric after the initial treatment, further enhancing the fulling effect, making the fleece fabric fibers more tightly bonded together, and achieving the ideal fulling state; preferably, the first air knife component 6 and the first support roller 4 are arranged horizontally side by side, and the first air knife component 6 is positioned near the fabric inlet of the first support roller 4. On one side, the second air knife component 7 and the second cloth support roller 5 are arranged vertically side by side, with the second air knife component 7 positioned directly above the second cloth support roller 5. The cloth support roller has a relatively small overall diameter. This small diameter design not only meets the processing requirements of multiple angles, allowing the fleece to better contact the hot air during processing and achieve a more uniform fleece treatment, but also ensures that the cloth support roller is made of high-quality steel and undergoes precise machining and surface treatment to ensure its surface smoothness and wear resistance, thereby ensuring the stability of the fleece during transmission and avoiding damage to the fleece surface.

[0018] Specifically: Both the first air knife component 6 and the second air knife component 7 include an air knife body 10 rotatably mounted on the fulling box 3. A drive motor 11 for adjusting the angle of the air knife body 10 is also installed on the fulling box 3. The air knife body 10 is mounted on the fulling box 3 via a rotating shaft. The motor shaft of the drive motor 11 is connected to the rotating shaft for transmission, which facilitates the control of the angle of the air knife body 10, thereby adjusting the direction of hot air jets. This allows the air knife body 10 to blow onto the surface of the fulling fabric at the optimal angle according to different fulling materials and fulling requirements, improving fulling quality and efficiency. The air knife body 10 is made of high-temperature resistant and corrosion-resistant materials, ensuring good performance and service life under long-term hot air blowing conditions.

[0019] To coordinate with the operation of the first air knife component 6 and the second air knife component 7, a left housing 8 is installed on the fabric rack 1 on one side of the fulling housing 3. A combustion assembly 2 is installed inside the left housing 8, with its gas distribution chamber 2.2 extending into the fulling housing and communicating with the first air knife component 6 and the second air knife component 7. A high-pressure blower 8.3 is also installed on the left housing 8 to cooperate with the combustion assembly 2. The left housing 8 also has a gas inlet 8.1 and a compressed air inlet 8.2 for easy input of gas and compressed air. This allows the ignition controller 2.1 of the combustion assembly 2 to generate high-temperature heat by igniting the gas and compressed air, providing a hot air source for the first air knife component 6 and the second air knife component 7. The high-temperature, high-pressure airflow passes through the narrow gaps of the first air knife component 6 and the second air knife component 7, directly acting on the surface of the felt to achieve the fulling effect. The high-pressure blower 8.3 is used to adjust the airflow and pressure entering the combustion assembly 2 according to different fulling stages and process requirements. By controlling the amount and speed of hot air generated, efficient felting treatment of various fleece fabrics can be achieved. The high-pressure blower 8.3 adopts advanced energy-saving technology, which reduces energy consumption while ensuring powerful performance, meeting the requirements of modern industrial energy conservation and environmental protection. At the same time, the blower operates with low noise, reducing noise pollution to the working environment. Preferably, the high-pressure blower 8.3 is provided in two sets with different specifications to provide different air volume and air pressure ranges. By using them in a reasonable combination, precise adjustment of the hot air can be achieved, improving the stability and consistency of the felting effect.

[0020] On the other side of the fulling box 3, a right box 9 is installed on the fabric arrangement frame 1. The guide roller 9.2, the first support roller 4, and the second support roller 5 all extend into the right box 9. A geared motor 9.1 is installed inside the right box 9 to drive the rotation of the guide roller 9.2, the first support roller 4, and the second support roller 5. Through precise control of the geared motor 9.1, the rotational speed of each roller can be adjusted, thereby controlling the conveying speed of the fleece within the fulling box 3. Different fleece materials and fulling processes have different requirements for conveying speed. The use of the geared motor 9.1 can meet these diverse needs, ensuring that the fleece receives hot air blowing and fulling treatment within the appropriate time to achieve the best fulling effect.

[0021] In actual use, a spreading roller 9.3 is also installed in the fulling box 3 at the guide roller 9.2 to fully spread the fulling cloth entering the fulling box 3, eliminate wrinkles that may be generated during the conveying process, ensure the smooth surface of the fulling cloth, and provide a good foundation for subsequent fulling treatment. Guide rollers 9.4 are also installed in the fulling box 3 at the guide roller 9.2, spreading roller 9.3, first support roller 4 and second support roller 5 to further guide the movement direction of the fulling cloth, ensure that the fulling cloth transitions smoothly between the rollers, and avoid jamming or tangling.

[0022] This application uses a fabric-laying frame 1 as the basic support structure, on which several key components, such as the fulling box 3, the left box 8, and the right box 9, are rationally arranged and installed. The fulling box 3 is the core area for fulling the fleece fabric. The left box 8 mainly houses the combustion assembly 2 and the high-pressure blower 8.3, as well as other heating and gas supply equipment. The right box 9 is used to install the reduction motor 9.1 that drives the guide roller 9.2, the first support roller 4, and the second support roller 5 to rotate. The components work together to achieve the fulling process of the fleece fabric. The specific working process is as follows: The felt to be felted enters the felting box 3 through the fabric input roller. First, it is guided and spread by the fabric guide roller 9.2 and the fabric spreading roller 9.3 to make the surface of the felt flat. Under the support of the first fabric support roller 4, the felt receives the hot air sprayed by the first air knife component 6 to fluff the felt. Then, the felt moves to the second fabric support roller 5 and receives the hot air sprayed by the second air knife component 7 for further processing to complete the felting process. Finally, the felted felt is led out of the felting box 3 through the fabric output roller.

[0023] Throughout the operation, the combustion component 2 continuously provides hot air to the air knife component, the high-pressure blower 8.3 adjusts the air supply as needed, and the geared motor 9.1 controls the conveying speed of the velvet. All components work together to ensure the stable and efficient operation of the equipment.
