Description
Technical Field
[0001] This utility model relates to the field of air volume regulation equipment technology, specifically an air volume regulation structure for the main air duct of a combing machine. Background Technology
[0002] The main air duct of a comber is a crucial component, playing a key role in guiding and controlling airflow. Its design directly impacts the uniformity and stability of airflow during cotton spinning, thus affecting the quality of the cotton web's overlap. Typically, the main air duct is made of metal or other durable materials and has a specific cross-sectional shape (such as square or circular). Its length, width, and height are optimized according to the specifications and performance requirements of the comber. By modifying the main air duct's structure, such as changing a square structure to a circular one, the airflow distribution can be improved, pressure energy loss reduced, and airflow smoother. In short, the main air duct of a comber is essential for ensuring the efficiency of the cotton spinning process and product quality.
[0003] The main purpose of using an airflow adjustment structure in the main air duct of a combing machine is to adapt to the needs of different cotton spinning processes and achieve precise airflow control. Different textile processes have different requirements for airflow. For example, when processing different types of fibers or combing different cotton, the required airflow and air velocity may vary significantly. If the airflow cannot be adjusted in time, it will directly affect the combing effect of the fibers and the quality of the final product. However, existing airflow adjustment structures often lack flexibility and cannot be adjusted in real time according to actual process requirements. Operators need to use external control devices to adjust the airflow, which not only increases the complexity of the equipment and the cost, but also significantly increases operating costs and maintenance difficulty. When a malfunction occurs, it affects production efficiency and product quality. Utility Model Content

The inner walls of the grooves of the first and second connecting frames are slidably fitted with insert plates for controlling and adjusting the airflow. The insert plates are made of high-temperature resistant and corrosion-resistant stainless steel. Two sets of sliders are fixed on both sides of the insert plates, and the outer sides of the multiple sets of sliders correspond one-to-one with the inner walls of the grooves of the first and second connecting frames. A handle for pulling or pushing the insert plate is fixed on one side of the insert plate.
[0007] Preferably, a mounting plate is fixed to the outer side of the bottom of the duct body, and multiple mounting bolts are threadedly connected to the inner wall of the mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This utility model uses the duct body and connecting cylinder in conjunction to control the airflow of the fan body. The first and second connecting frames separate the connecting cylinder, forming a sliding channel for the insert plate. The insert plate can slide along the grooves of the first and second connecting frames. By adjusting its insertion depth, the airflow can be controlled to ensure that the airflow of each combing machine is balanced, avoiding the problem of excessive airflow near the dust removal end and insufficient airflow at the far end. When a fire occurs in a single machine, the insert plate can be quickly closed to block the airflow and prevent the fire from spreading to the dust removal device. The device has a simple structure, is easy to operate, and effectively improves the accuracy and safety of airflow adjustment. Attached Figure Description

The insert plates 5 are made of high-temperature and corrosion-resistant stainless steel. Two sets of sliders 6 are fixed on both sides of the insert plates 5. The sliders 6 are slidably connected to the grooves in the first connecting frame 3 and the second connecting frame 4 to ensure the stability of the insert plates 5 when moving. The outer sides of the multiple sets of sliders 6 correspond one-to-one with the inner walls of the grooves in the first connecting frame 3 and the second connecting frame 4. A handle 7 is fixed on one side of the insert plate 5 for pulling or pushing the insert plate 5 to move it. By setting the handle 7, it is convenient for the staff to push or pull the insert plate 5 to move it, thereby adjusting the airflow.
[0022] A mounting plate 8 is fixed to the outer side of the bottom of the duct body 1. Multiple mounting bolts 9 are threaded onto the inner wall of the mounting plate 8, and the mounting bolts 9 are used to connect the duct body 1 and the fan body. By setting the duct body 1, it is easy to fix it to the mounting plate 8, ensuring the installation position of the multiple mounting bolts 9. By setting multiple mounting bolts 9, the mounting plate 8 can be easily installed outside the fan body, which facilitates the installation of the main body, improves the connection between the duct body 1 and the fan body, and also ensures the airtightness of the connection between the duct body 1 and the fan body.
[0023] A first connecting plate 10 is fixed to the outer side of the lower end of the connecting cylinder 2. A second connecting plate 11 is provided at the bottom of the first connecting plate 10, and the inner wall of the second connecting plate 11 is fixedly connected to the outer side of the top of the duct body 1. By setting the connecting cylinder 2, the first connecting plate 10 can be easily fixed. The first connecting plate 10 can be easily connected to the second connecting plate 11. By setting the duct body 1, the second connecting plate 11 can be easily fixed. The cooperation between the first connecting plate 10 and the second connecting plate 11 facilitates the connection between the duct body 1 and the connecting cylinder 2. The inner walls of the first connecting plate 10 and the second connecting plate 11 are threaded with multiple long bolts 12. The outer side of the long bolts 12 is threaded with limit nuts 13, and the limit nuts 13 are located on the top of the first connecting plate 10 to limit the long bolts 12. By setting multiple sets of long bolts 12 and limit nuts 13 for cooperation, the connection between the first connecting plate 10 and the second connecting plate 11 can be facilitated, thereby improving the sealing performance when the duct body 1 and the connecting cylinder 2 are connected.
[0024] Multiple sets of mounting clamps 14 are fixed to the outer side of the connecting cylinder 2. Each set of mounting clamps 14 has an insertion hole on its inner wall, and mounting nails 15 are inserted into the inner wall of each insertion hole. The connecting cylinder 2 facilitates the fixing of the mounting clamps 14, and the insertion holes within the mounting clamps 14 facilitate the insertion of the mounting nails 15. A mounting bracket 16 is inserted into the outer side of the mounting nails 15. Multiple sets of fixing bolts 17 are threaded onto the inner wall of the mounting bracket 16, and the outer sides of the fixing bolts 17 are threaded into the inner wall of the first connecting frame 3. The mounting nails 15 facilitate the installation of the mounting bracket 16. By using the mounting bracket 16 and fixing bolt 17 together, the stability of the first connecting frame 3 can be easily improved. It should be noted that the bottom of the second connecting frame 4 is also provided with the mounting hoop 14, mounting nail 15, mounting bracket 16 and fixing bolt 17. In order to improve the stability of the second connecting frame 4, the process is as follows: first, the mounting bracket 16 is inserted into the mounting hoop 14, then the mounting nail 15 is inserted into the mounting hoop 14 and the mounting bracket 16 respectively, and then the fixing bolt 17 is screwed into the mounting bracket 16 and connected to the first connecting frame 3. The structure of the bottom of the second connecting frame 4 is installed in the same way as above.
[0025] The inner walls of the first connecting frame 3 and the second connecting frame 4 are threaded with multiple connecting bolts 18, and the connecting bolts 18 are used to improve the sealing when the first connecting frame 3 and the second connecting frame 4 are connected. By setting the connecting bolts 18, the connection between the first connecting frame 3 and the second connecting frame 4 can be facilitated. It should be noted that the connecting bolts 18 are threaded with connecting nuts to prevent the connecting bolts 18 from loosening and to prevent the connecting bolts 18 from falling out of the first connecting frame 3 and the second connecting frame 4.
[0026] Working principle: First, the duct body 1 and mounting plate 8 are fixed to the air outlet of the fan body using mounting bolts 9, ensuring a secure connection. Then, the connecting cylinder 2 is connected to the duct body 1 via the first connecting plate 10, the second connecting plate 11, and the long bolts 12, forming a complete duct structure. Next, the first connecting frame 3 and the second connecting frame 4 are installed inside the connecting cylinder 2, and the two are tightly connected and sealed using connecting bolts 18, ensuring the airtightness of the duct. Finally, the insert plate 5 and slider 6 are inserted into the first connecting frame 3 and the second connecting frame 4 via the handle 7, completing the main installation. When airflow needs adjustment... At the same time, the operator can control the movement of the insert plate 5 and the slider 6 through the handle 7. If the air volume needs to be increased, pull the handle 7 outward to move the insert plate 5 and the slider 6 outward along the first connecting frame 3 and the second connecting frame 4, thereby expanding the through hole area in the connecting cylinder 2 and increasing the air volume. If the air volume needs to be reduced, push the handle 7 inward to move the insert plate 5 and the slider 6 inward to reduce the through hole area in the connecting cylinder 2 and reduce the air volume. Through the sliding adjustment of the insert plate 5, the air volume can be precisely controlled, ensuring the high efficiency and stability of the system operation. The device has a simple structure, is easy to operate, and is suitable for various air volume adjustment scenarios.
