[0008] Preferably, the interlacer includes an interlacer housing. A filament interlacing cavity for precursor interlacing is formed in the middle of the interlacer housing. A wire inlet channel communicating with the outside is formed on the interlacer housing. Two gas exchange cavities are formed inside the left and right sides of the interlacer housing around the filament interlacing cavity.

[0015] Next, through embodiments and in combination with the drawings, the technical solutions of the present utility model will be further specifically described.
[0016] Embodiment: An interlacing device for carbon fiber raw yarn production, as Figures 1 - 3 shown, includes a mounting plate 2, characterized in that: a first tension sensor 1 is arranged on the top of the mounting plate 2, a second tension sensor 5 is arranged on the bottom of the mounting plate 2, yarn guiding rollers 3 are arranged on the sides of the first tension sensor 1 and the second tension sensor 5 facing each other, the first tension sensor 1, the yarn guiding roller 3, and the second tension sensor 5 are all inserted through the mounting plate 2 front and back, and are connected to the mounting plate 2 at the insertion point by nuts. An interlacer 4 is arranged between the two yarn guiding rollers 3. Two connectors 8 are arranged at the bottom of the interlacer 4. Air pipes 9 are connected to the tops of the two connectors 8. One end of the air pipe 9 penetrates through the mounting plate 2 and extends to the rear side of the mounting plate 2. A pad 10 is arranged at the rear side of the interlacer 4. The interlacer 4 is installed on the mounting plate 2 through the pad 10. A position-adjustable yarn guiding roller group 6 is arranged on the front side of the second tension sensor 5.
[0017] Smart meters 7 are connected to the rear sides of both the first tension sensor 1 and the second tension sensor 5; they can record and display the tow tension data, which is beneficial for subsequent production optimization.
[0018] The interlacer 4 includes an interlacer 4 housing. A tow interlacing cavity 4.6 for the primary yarn interlacing is formed in the middle of the interlacer 4 housing. A wire inlet channel 4.5 communicating with the outside is formed on the interlacer 4 housing. Two gas exchange cavities 4.3 are formed inside the left and right sides of the interlacer 4 around the tow interlacing cavity 4.6. A plurality of gas exchange slots 4.4 for blowing the primary yarn to rotate and interlace are formed on the partition between the gas exchange cavity 4.3 and the tow interlacing cavity 4.6. Threaded ports 4.2 are arranged on the left and right sides of the bottom of the interlacer 4. The two threaded ports 4.2 communicate with the two gas exchange cavities 4.3 respectively. The bottom of the threaded port 4.2 is connected to the interface.
[0019] The principle of the present utility model: The carbon fiber primary yarn passes through the first tension sensor 1 at the top and then goes down through the yarn guiding roller 3 to the tow interlacing cavity 4.6 of the interlacer 4. At the same time, the interlacer 4 injects high-pressure gas into the gas exchange cavity 4.3 through two groups of air pipes 9 at the bottom. The gas rushes into the tow interlacing cavity 4.6 through the gas exchange slots 4.4. The gas exchange slots 4.4 are divided into multiple ones and are opened on the partition between the tow interlacing cavity 4.6 and the gas exchange cavity 4.3 at the same angle in the clockwise direction. Through the set angle, the blown gas forms a cyclone in the tow interlacing cavity 4.6, so that multiple single filaments in the tow can be blown apart and interlaced and wound. Then, it goes down through the yarn guiding roller 3 again and is sent to the second tension sensor 5. The smart meters 7 connected to the rear sides of the first tension sensor 1 and the second tension sensor 5 can monitor the tension data, which is convenient for personnel to adjust the tension and record the data. Finally, the primary yarn is led into the next process through the yarn guiding roller group 6.
[0020] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model should be considered to fall within the protection scope of the present utility model.
