Description

Technical Field

[0001] This utility model relates to the field of textile production technology, and in particular to a dual-channel air blowing and cooling device. Background Technology

[0002] The dual-duct air blowing cooling device is a device specifically used to cool down the spinning process. Its core feature is that it has two independent air duct systems. During the spinning process, the molten spinning raw material is extruded from the spinneret to form filaments. At this time, the temperature of the filaments is high and needs to be cooled and solidified.

[0003] Check both air ducts for blockages, damage, or leaks. Remove any debris. Inspect the fan blades for damage, deformation, cracks, or loosening. Verify the temperature sensor is securely installed and accurately positioned. Determine the required cooling air temperature, speed, and volume for both air ducts. Start the fan in one air duct first, and once it is running stably, start the fan in the other air duct. Fine-tune the speed and volume of the two air ducts according to the actual spinning conditions. Turn off the fans in both air ducts first, and once they have completely stopped running, turn off the temperature control system and other related equipment.

[0004] Existing side-blowing devices can only act on one side or a local surface of the spinning process for spinning varieties with larger filament diameters. This makes it difficult for the heat inside the spinning process to dissipate quickly, resulting in incomplete cooling and uneven filament diameter. This seriously affects product quality and production efficiency. They cannot be flexibly adjusted according to the characteristics of different spinning materials and production process requirements, and are difficult to adapt to the differentiated cooling needs of various spinning varieties such as polyester, nylon, and acrylic. This limits the multifunctionality of the production line and the expansion of production scale. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This solves the problem that existing equipment cannot be used for spinning different yarn diameters, avoids incomplete cooling, and improves product quality and efficiency.

[0007] (II) Technical Solution

[0008] In view of the above-mentioned problem of uneven fiber output, this utility model is proposed.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dual-duct air blowing and cooling device, including a body, an air blowing chamber opened on the inner wall of the body, a wind duct body connector fixedly connected to the outer wall of the body, a pipe communicating with the inner wall of the air blowing chamber opened at the top of the wind duct body connector, a partition fixedly connected to the inner wall of the pipe, an upper air pipe communicating with the inner wall of the air blowing chamber opened on the inner wall of the wind duct body connector, a lower air pipe communicating with the inner wall of the air blowing chamber opened on the inner wall of the wind duct body connector, air valves slidably connected to the inner walls of the lower air pipe and the upper air pipe, and two horizontally movable adjusting plates slidably connected to both sides of the outer wall of the partition.

[0010] As a preferred embodiment of the dual-duct cooling device of the present invention, the bottom of the inner wall of the air duct body is provided with a ventilation pipe that communicates with the inner walls of the upper and lower air ducts; the inner wall of the air valve is fixedly connected with a rotating rod that is slidably connected to the inner wall of the air duct body; and the outer wall of the air duct body is fixedly connected with an actuator that is fixedly connected to the outer wall of the rotating rod.

[0011] As a preferred embodiment of the above-mentioned dual-duct air blowing and cooling device, the outer wall of the duct is fixedly connected to an installation block that is fixedly connected to the outer wall of the machine body. The inner wall of the installation block is provided with an adjustment groove to facilitate the sliding of the adjustment plate. The inner walls of the two adjustment plates are threadedly connected to a bidirectional screw rod that is slidably connected to the inner wall of the partition.

[0012] As a preferred embodiment of the above-mentioned dual-channel air blowing and cooling device, the outer wall of the adjusting plate is fixedly connected with a sliding block, and both sides of the outer wall of the partition are provided with sliding grooves to facilitate the sliding of the sliding block.

[0013] As a preferred embodiment of the dual-duct cooling device of the present invention, the outer wall of the bidirectional screw is fixedly connected to a mounting cylinder that is slidably connected to the inner wall of the mounting block, the inner wall of the mounting cylinder is slidably connected to a handle, and the inner wall of the mounting cylinder is slidably connected to a sliding plate.

[0014] As a preferred embodiment of the above-mentioned dual-channel air blowing and cooling device, a spring is connected between the outer wall of the sliding plate and the outer wall of the handle, two mirror-distributed limiting blocks are fixedly connected to the outer wall of the handle, and a limiting groove is provided on the inner wall of the mounting cylinder to facilitate the sliding of the limiting blocks.

[0015] The beneficial effects of this utility model are:

[0016] 1. By turning the handle, the operator drives the bidirectional lead screw to rotate, which in turn drives the adjustment plate to precisely fine-tune the width of the upper and lower air ducts. According to different spinning process requirements, the size of the air outlet can be flexibly adjusted. For coarser spinning, the air outlet width is reduced to increase the airflow speed, enhance the cooling effect, accelerate heat dissipation, and ensure spinning quality. For fine spinning, the air outlet width is increased to reduce the airflow speed and avoid damage to the fragile spinning fibers caused by high-speed airflow. This precise adjustment capability enables the device to adapt to various spinning production needs, significantly improving the applicability of the equipment and the quality stability of the spun products.

[0017] 2. By driving the air valve to rotate through the actuator, the full opening or closing of the upper and lower air ducts can be precisely controlled, flexibly cutting off or guiding the airflow of a certain duct to meet the production needs under different working conditions. At the same time, the adjustment function of the air valve can effectively balance the pressure difference between the upper and lower branches, ensuring uniform airflow distribution. By adjusting the angle of the air valve, the air supply volume of the upper and lower air ducts can also be precisely adjusted, so that the device can maintain the best blowing effect under various working conditions, which not only improves the cooling efficiency, but also reduces energy consumption and extends the service life of the equipment.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-3 This is the first embodiment of the present invention, which provides a dual-duct air blowing and cooling device, including a body 1. The inner wall of the body 1 has an air blowing chamber 7. The outer wall of the body 1 is fixedly connected to a duct body connector 2. The top of the duct body connector 2 has a pipe 4 communicating with the inner wall of the air blowing chamber 7, so that the air volume ratio of the upper air pipe 8 and the lower air pipe 9 is maintained at 1:1.2 to 1.5. A partition 10 is used to improve the longitudinal wind speed difference. The inner wall of the duct body connector 2 has an upper air pipe 8 communicating with the inner wall of the air blowing chamber 7. The inner wall of the duct body connector 2 has a lower air pipe 9 communicating with the inner wall of the air blowing chamber 7. The inner walls of the lower air pipe 9 and the upper air pipe 8 are slidably connected to air valves 12. The air valves 12 are controlled by actuators 3 to open and close the angle and adjust the airflow area of ​​the air pipes. Two horizontally movable adjusting plates 14 are slidably connected to both sides of the outer wall of the partition 10. The adjusting plates 14 are used to adjust the airflow speed of the upper air pipe 8 and the lower air pipe 9.

[0028] The bottom of the inner wall of the air duct body connector 2 is provided with a ventilation pipe 6 that communicates with the inner walls of the upper air duct 8 and the lower air duct 9. The ventilation pipe 6 is powered by a fan. The inner wall of the air valve 12 is fixedly connected to a rotating rod 11 that is slidably connected to the inner wall of the air duct body connector 2. The outer wall of the air duct body connector 2 is fixedly connected to an actuator 3 that is fixedly connected to the outer wall of the rotating rod 11. The actuator 3 is used to control the rotation of the air valve 12.

[0029] The outer wall of the pipe 4 is fixedly connected to the mounting block 5, which is fixedly connected to the outer wall of the body 1. The inner wall of the mounting block 5 is provided with an adjustment groove to facilitate the sliding of the adjustment plate 14. The inner walls of the two adjustment plates 14 are threadedly connected to a bidirectional screw rod 13 that is slidably connected to the inner wall of the partition plate 10. The bidirectional screw rod 13 is used to drive the adjustment plate 14 to move along the sliding block.

[0030] During use, the operator holds the handle 16 and pushes it inward. At this time, the handle 16 drives the limiting block 17 to slide along the limiting groove 19 on the inner wall of the mounting cylinder 15 until the limiting block 17 slides out of the vertical section of the limiting groove 19. Then, the operator rotates the handle 16. Since the handle 16 is fixedly connected to the bidirectional lead screw 13, the bidirectional lead screw 13 rotates accordingly. The bidirectional lead screw 13 is threadedly connected to the two adjusting plates 14. During the rotation, the bidirectional lead screw 13 drives the two adjusting plates 14 to move horizontally along the sliding groove on the outer wall of the partition 10, thereby blocking the openings of the upper air duct 8 or lower air duct 9 on both sides of the partition 10, thus adjusting the flow area of ​​the air duct.

[0031] After adjustment, release handle 16. Under the elastic force of spring 18, handle 16 drives limit block 17 to slide and reset to the outside of mounting cylinder 15. Since the cross-section of limit groove 19 is "T" shaped and the top limit groove 19 is annular, limit block 17 can be stably locked into limit groove 19, preventing handle 16 from rotating due to accidental contact, thereby avoiding changes in the position of the adjusted plate 14.

[0032] Example 2

[0033] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a sliding block is fixedly connected to the outer wall of the adjusting plate 14, and sliding grooves are provided on both sides of the outer wall of the partition plate 10 to facilitate the sliding of the sliding block.

[0034] The outer wall of the bidirectional lead screw 13 is fixedly connected to the mounting cylinder 15, which is slidably connected to the inner wall of the mounting block 5. The inner wall of the mounting cylinder 15 is slidably connected to the handle 16, which is used to drive the bidirectional lead screw 13 to rotate. The inner wall of the mounting cylinder 15 is slidably connected to the sliding plate 20.

[0035] A spring 18 is connected between the outer wall of the sliding plate 20 and the outer wall of the handle 16. The spring 18 is used to push the handle 16. Two limit blocks 17 are fixedly connected to the outer wall of the handle 16 in a mirror distribution. The inner wall of the mounting cylinder 15 is provided with a limit groove 19 to facilitate the sliding of the limit block 17. The cross-section of the limit groove 19 is "T" shaped.

[0036] During use, if it is necessary to adjust the air volume of the upper air duct 8 and the lower air duct 9, the actuator 3 on the outer wall of the air duct body connector 2 can be activated. The actuator 3 is fixedly connected to the rotating rod 11. After receiving the control signal, the actuator 3 drives the rotating rod 11 to rotate. The rotating rod 11 is fixedly connected to the air valve 12, thereby driving the air valve 12 to rotate on the inner wall of the air duct. As the air valve 12 rotates, its obstruction area for the airflow in the air duct changes, thereby realizing the adjustment of the air volume of the upper air duct 8 and the lower air duct 9. Through the precise control of the actuator 3, the air volume of the upper and lower air ducts can be flexibly adjusted according to the actual cooling needs to achieve different blowing and cooling effects. The operation is now complete.

[0037] The remaining structure is the same as that in Example 1.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
