At the same time, the airflow generated by the traditional air jet holes is not fine enough, so that the flat fibers are unevenly stressed during the interlacing process, which is prone to fiber damage.

[0005] Therefore, in view of the above problems, an FDY networker for processing flat fibers is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] As attached Figures 1 to 4 The FDY network device for processing flat fibers shown in the figure includes a base 1, which is made of metal material and plays a supporting and protective role. The outer wall of the base 1 is connected to a support plate 2, which is connected to the base 1 by bolts to provide a limiting support for the flat fiber network. A No. 1 limit block 3 is arranged on the top of the support plate 2. The No. 1 limit block 3 is provided in several groups, and the No. 1 limit block 3 is evenly arranged in the horizontal direction along the top of the support plate 2, providing the device with several production lines that can work simultaneously, thereby improving the production speed. A guide rail 4 is arranged below the No. 1 limit block 3. The guide rail 4 is made of metal material, which can prolong the service life and provide higher structural strength. A No. 2 limit block 5 is connected above the guide rail 4, and the No. 2 limit block 5 is provided with Several groups, and the No. 2 limit block 5 is evenly arranged in the horizontal direction of the guide rail 4. The No. 1 limit block 3 and the No. 2 limit block 5 are combined to form a clamping structure for clamping the flat fiber, limiting the position movement range of the flat fiber during weaving. Such a design can ensure that flat fibers of different specifications can smoothly enter the network nozzle 7, avoiding blockage or damage caused by mismatched specifications, adapting to diverse flat fiber sizes, improving the versatility and processing range of the machine, reducing downtime and adjustment time due to changing material specifications, and improving production efficiency. A clamping tooth 6 is provided on one side of the guide rail 4. The clamping tooth 6 is a rectangular parallelepiped structure made of metal material. The movement of the guide rail 4 is limited by cooperating with the clamping pin 13. The guide rail 4 is fixed after the limit size is adjusted, which is convenient for the staff to operate;

[0027] A network nozzle 7 is arranged at the top center of the base 1. The network nozzle 7 is cylindrical and includes an outer shell 8 and a nozzle core 9. The outer shell 8 is the main structure of the entire nozzle and is usually made of high-strength, high-temperature resistant materials to withstand high-pressure airflow and the harsh environment in chemical fiber production. A nozzle core 9 is arranged inside the outer shell 8. The nozzle core 9 is one of the key components that affect the performance of the network nozzle 7. Its design form can be diverse, but it must be precisely manufactured to ensure accurate guidance and speed control of the airflow. The nozzle core 9 cooperates with the outer shell 8 to form an airflow channel. By adjusting the position of the nozzle core 9, the speed and pressure of the airflow can be changed to adapt to different processing requirements. A nozzle core 9 made of ceramic material is usually used.

[0028] Among them: a vortex groove 10 is arranged on the inner wall of the nozzle core 9, and there are two groups of vortex grooves 10, and the two groups of vortex grooves 10 are symmetrically arranged on the nozzle core 9, each vortex groove 10 adopts a curved shape, and the depth and width of the groove are optimized to produce a more uniform air pressure distribution. The shape of the vortex groove 10 is designed based on fluid dynamics simulation to ensure that a stable vortex effect can be formed when the air flows. The two groups of vortex grooves 10 are symmetrically arranged inside the network nozzle 7, and their relative positions and angles are precisely calculated to promote interaction during air flow and enhance the network effect. By precisely controlling the air pressure entering the vortex groove, it is ensured that the fiber is subjected to equal force during the network process, thereby improving the uniformity of the network points. The air flow path is specially designed so that the compressed air can create a high-speed rotating airflow when passing through the vortex groove 10. Such a design is conducive to the formation and uniform distribution of network points.

[0029] Example 2

[0030] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 4 As shown, see the following description for details:

[0031] As a preferred embodiment, rollers 11 are provided below the guide rail 4. There are several groups of rollers 11, and each group of rollers 11 is evenly arranged in the horizontal direction along the bottom of the guide rail 4. The rollers 11 make the movement of the guide rail 4 smooth, and rolling in the track can prevent the position of the guide rail 4 from shifting when it moves.

[0032] As a preferred embodiment, a buffer pad 12 is provided on one side of the roller 11. The buffer pad 12 is a plate-like structure supported by rubber material, which can absorb the collision force when the guide rail 4 is retracted, thereby extending the service life of the equipment. The guide rail 4 can translate left and right along the horizontal direction of the support plate 2 through the roller 11.

[0033] As a preferred embodiment, a latch 13 is provided on one side of the support plate 2. The latch 13 is a metal structure made of metal material and has multiple slots. The guide rail 4 can be fixed in the latch 13 through the latch tooth 6. By rotating the position of the latch tooth 6 on the guide rail 4, the latch tooth 6 can be limited in the latch 13 to limit the movement of the guide rail 4.

[0034] As a preferred embodiment, two groups of support plates 2 are provided, and the two groups of support plates 2 are respectively arranged at both ends of the network nozzle 7. Through the arrangement on both sides, the flat fiber is limited when entering and leaving the network nozzle 7, thereby ensuring the stability of the flat fiber during high-speed movement.

[0035] As a preferred embodiment, a swing plate 14 is connected to one side of the outer wall of the base 1, and a wire pressing rod 15 is connected to one side of the swing plate 14. The wire pressing rod 15 adjusts the fiber tension so that each fiber can be intertwined under the same conditions, thereby optimizing the network effect. This optimization not only improves the network quality, but also ensures the consistency and high-quality rate of the finished products. A compressed air connector 16 is connected to one side of the network nozzle 7, which provides high-speed airflow through the connection with compressed air to network the flat fibers.

[0036] As a preferred embodiment, several groups of network nozzles 7 are provided, and each group of network nozzles 7 is evenly arranged in the horizontal direction along the top of the base 1, so that the device can process multiple groups of fibers at the same time, thereby improving work efficiency.

[0037] As a preferred embodiment, the outer walls of the No. 1 limit block 3 and the No. 2 limit block 5 are both provided with holes, so that the flat fiber can accurately enter the network nozzle 7 through the holes. These holes need to be designed according to the width of the flat fiber to ensure that the fiber can pass smoothly and will not loosen. The size of the hole should be slightly larger than the width of the fiber to provide sufficient space to avoid fiber damage or blockage caused by operating errors. The No. 1 limit block 3 and the No. 2 limit block 5 are made of flexible materials. Both should have sufficient elasticity and wear resistance to maintain good performance during long-term use. At the same time, the material should have good anti-slip properties to ensure that the fiber can maintain appropriate tension when passing through the hole to avoid sliding or displacement.

[0038] The working process of the utility model is as follows: first, the compressed air is connected to the compressed air connector 16, and then the flat fiber is placed in the gap of the No. 1 limit block 3, and the position of the No. 2 limit block 5 is adjusted through the guide rail 4 so that the two can wrap the flat fiber, and at the same time, a certain gap is left around the flat fiber, and then the flat fiber passes through the network nozzle 7, and passes through the limit groove composed of the No. 1 limit block 3 and the No. 2 limit block 5 on the support plate 2 on the other side, and then the device is started. Thanks to the design of the double spiral groove 10 on the nozzle core 8 inside the network nozzle, a more uniform network node is formed. This design helps to improve the network uniformity and fastness of the processed wire, and at the same time, the wire pressing rod 15 is contacted with the flat fiber through the swing plate 14, so that each fiber can be intertwined under the same conditions, thereby optimizing the network effect. The above is the working principle of the spiral forming drill and milling cutter for cutting aluminum.

[0039] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
