In the process of the spinneret 2 spraying the spinning solution, the pipeline for introducing the cooling liquid can be fixed to the inside of the second screw hole 102, and then the cooling liquid flows into the interior of the second liquid guide cavity 7 through the second liquid guide tube 6, and then the cooling liquid can be sprayed out from the liquid outlet hole, and then sprayed on the surface of the spinning solution sprayed from the spinneret 2, so that the spinning solution is quickly cooled, thereby effectively avoiding the dust and other impurities in the air from mixing into the interior of the spinning solution during the spraying process, thereby causing pollution to the formed fiber filaments.

[0034] like Figures 1 to 5As shown, the adjustment component includes a mounting frame 8; a sliding block 10 is fixedly connected to the top of the mounting frame 8; the sliding block 10 is slidably connected to the inside of the spinneret frame 1; a mounting hole 9 is provided inside the mounting frame 8; the spinneret 2 is threadedly connected to the inside of the mounting hole 9; a second liquid guide cavity 7 is provided inside the mounting frame 8; a sliding plate 11 is slidably connected to the inside of the spinneret frame 1; a fixing frame 12 is fixedly connected to the side walls of the spinneret frame 1 and the sliding plate 11; the two fixing frames 12 are arranged correspondingly; the fixing frame 12 fixed on the side wall of the spinneret frame 1 is not threaded inside, and the fixing frame 12 fixed on the side wall of the sliding plate 11 is threaded inside and is threadedly connected to the fixing bolt 13; the fixing bolt 13 is rotatably connected to the fixing frame 12 fixed on the side wall of the spinneret frame 1 The fixing bolt 13 is inside the fixing frame 12 on the wall; during operation, when the position of the mounting frame 8 needs to be adjusted, the fixing bolt 13 can be rotated, and then the threaded cooperation between the fixing bolt 13 and the fixing frame 12 can make the sliding plate 11 rise, and then the mounting frame 8 can be pulled to adjust the position of the mounting frame 8, so that the distance between the spinnerets 2 can be adjusted. After the adjustment is completed, the fixing bolt 13 can be rotated so that the fixing bolt 13 drives the sliding plate 11 to descend, and then the sliding block 10 on the top of the mounting frame 8 is pressed by the sliding plate 11, so that the function of adjusting the spacing of the mounting frame 8 can be realized. Adjusting the spacing of the mounting frame 8 can effectively avoid the situation that the fiber filaments are easily knotted when the spinneret 2 sprays the spinning solution to form fiber filaments, making the use of the device more convenient.

[0035] like Figure 3 As shown, a sealing ball 14 is provided inside the liquid outlet hole opened on the side wall of the second liquid guiding cavity 7; a spring is fixedly connected between the side wall of the sealing ball 14 and the inner wall of the second liquid guiding cavity 7; during operation, when the coolant flows into the interior of the second liquid guiding cavity 7 and then flows out through the liquid outlet hole, the coolant will push out the sealing ball 14, and then the coolant can be sprayed out through the liquid outlet hole to cool the spinning stock solution sprayed from the spinneret 2, and by arranging the sealing ball 14 at the liquid outlet hole, it is possible to effectively prevent the spinning stock solution from entering the interior of the second liquid guiding cavity 7, which may easily cause the second liquid guiding cavity 7 to be blocked. At the same time, when the coolant is sprayed out from the liquid outlet hole, the sealing ball 14 will block the coolant, so that the coolant will be sprayed around the sealing ball 14, so that the range of cooling liquid spraying can be larger and the effect of cooling the spinning stock solution can be better.

[0036] like Figure 1 and Figure 4As shown, a positioning rod 15 is fixedly connected to the inside of the spinneret frame 1; the positioning rod 15 is arranged at a position corresponding to the sliding plate 11; a positioning hole is opened inside the sliding plate 11; the positioning rod 15 and the positioning hole are arranged correspondingly; during operation, when the sliding plate 11 is sliding, the positioning rod 15 restricts the positioning hole, so that the sliding plate 11 is less likely to tilt during the sliding process, making the sliding of the sliding plate 11 more stable.

[0037] like Figure 4 and Figure 6 As shown, a fixing pad 16 is fixedly connected to the side wall of the positioning rod 15; the fixing pad 16 is arranged on the side wall of the positioning rod 15 close to the mounting frame 8; when working, when the sliding plate 11 is pressed down to fix the sliding block 10, by arranging the fixing pad 16 on the side wall of the sliding block 10, the contact area between the sliding plate 11 and the sliding block 10 can be made larger, so that the friction between the sliding plate 11 and the sliding block 10 can be made larger, so that the fixing effect of the sliding plate 11 on the sliding block 10 is better, and the sliding block 10 is effectively avoided from moving after being fixed.

[0038] like Figure 3 and Figure 7 As shown, a guide plate 17 is fixedly connected to the interior of the second liquid guide cavity 7; a plurality of guide grooves 18 are provided on the top of the guide plate 17, and the guide grooves 18 are regularly arranged in a circular array on the top of the guide plate 17; during operation, when the coolant flows into the interior of the second liquid guide cavity 7 through the second liquid guide pipe 6, the guide plate 17 can guide the coolant so that the coolant can better flow to the position of the liquid outlet, and the guide grooves 18 are provided on the surface of the guide plate 17, which can achieve a better effect of guiding the coolant.

[0039] like Figure 3 As shown, the mounting frame 8 is internally rotatably connected with a plurality of anti-wear wheels 19; the anti-wear wheels 19 are arranged at positions corresponding to the mounting holes 9; the anti-wear wheels 19 are regularly arranged in a circular array around the mounting holes 9; when working, when the spinneret 2 sprays the spinning solution to form fiber filaments, when the fiber filaments are wound up, the anti-wear wheels 19 can reduce the friction between the fiber filaments and the side walls of the mounting hole 9, thereby effectively preventing the fiber filaments from being affected by the friction and causing the fiber filaments to break.

[0040] like Fig. 9As shown, an anti-skid pad 20 is fixedly connected to the surface of the anti-skid wheel 19; the shape and size of the anti-skid pad 20 are arranged corresponding to the side wall of the anti-skid wheel 19; during operation, when the anti-skid wheel 19 guides the fiber filaments, by arranging the anti-skid pad 20 on the surface of the anti-skid wheel 19, the friction between the fiber filaments and the anti-skid wheel 19 can be made greater, so that the anti-skid wheel 19 can rotate better, thereby effectively avoiding the anti-skid wheel 19 from being stuck and unable to rotate, resulting in sliding friction between the fiber filaments and the anti-skid wheel 19.

[0041] like Figure 3 and Figure 6 As shown, the interior of the sliding block 10 is buckled and connected with a plurality of balls 21; the interior of the spinneret frame 1 is provided with a rolling groove 22; the balls 21 and the rolling groove 22 are arranged correspondingly; during operation, when the sliding block 10 slides inside the spinneret frame 1, the balls 21 can convert the sliding friction between the sliding block 10 and the spinneret frame 1 into rolling friction, so that the friction between the sliding block 10 and the spinneret frame 1 is smaller, thereby reducing the wear between the sliding block 10 and the spinneret frame 1.

[0042] like Figure 8 As shown, an anti-skid groove 23 is provided on the side wall of the spinneret 2; a plurality of anti-skid grooves 23 are provided on the side wall of the spinneret 2; during operation, when the spinneret 2 is installed into the installation hole 9, by providing the anti-skid grooves 23 on the surface of the spinneret 2, the contact area between the operator's hand or the installation tool and the spinneret 2 can be larger, thereby reducing the chance of slipping when the spinneret 2 is rotated, making the installation of the spinneret 2 more convenient.

[0043] During operation, when it is necessary to produce fiber filaments, the pipe for introducing the spinning solution can be fixed on the side wall of the spinneret frame 1 through the first screw hole 101, and then the spinning solution is introduced into the first liquid guide cavity 3 through the pipe, and then the spinning solution flows into the interior of the spinneret 2 through the first liquid guide tube 4, and then the spinning solution is sprayed out through the spinneret 2, and then the spinning solution is cooled to form fiber filaments. In the process of the spinneret 2 spraying the spinning solution, the pipe for introducing the cooling liquid can be fixed to the inside of the second screw hole 102, and then the cooling liquid flows into the interior of the second liquid guide cavity 7 through the second liquid guide tube 6, and then the cooling liquid can be sprayed out from the liquid outlet hole, and then sprayed on the surface of the spinning solution sprayed from the spinneret 2, so that the spinning solution is quickly cooled, thereby effectively avoiding the dust and other impurities in the air from mixing into the interior of the spinning solution during the spraying process, thereby causing pollution to the formed fiber filaments.

[0044] When the position of the mounting frame 8 needs to be adjusted, the fixing bolt 13 can be rotated, and then the fixing bolt 13 and the fixing frame 12 can be threadedly matched, so that the sliding plate 11 can be raised, and then the mounting frame 8 can be pulled to adjust the position of the mounting frame 8, so that the distance between the spinnerets 2 can be adjusted. After the adjustment is completed, the fixing bolt 13 can be rotated so that the fixing bolt 13 drives the sliding plate 11 to descend, and then the sliding block 10 on the top of the mounting frame 8 is pressed by the sliding plate 11, so that the function of adjusting the spacing of the mounting frame 8 can be realized. Adjusting the spacing of the mounting frame 8 can effectively avoid the situation where the fiber filaments are easily knotted when the spinneret 2 sprays the spinning solution to form fiber filaments, making the use of the device more convenient.

[0045] When the coolant flows into the interior of the second liquid guiding cavity 7 and then flows out through the liquid outlet, the coolant will push out the blocking ball 14, and then the coolant can be sprayed out through the liquid outlet to cool the spinning stock solution sprayed out of the spinneret 2. By arranging the blocking ball 14 at the liquid outlet, it is possible to effectively prevent the spinning stock solution from entering the interior of the second liquid guiding cavity 7, which may easily cause the second liquid guiding cavity 7 to be blocked. At the same time, when the coolant is sprayed out from the liquid outlet, the blocking ball 14 will block the coolant, so that the coolant will be sprayed around the blocking ball 14, so that the range of the coolant spraying can be larger and the effect of cooling the spinning stock solution can be better.

[0046] When the sliding plate 11 is sliding, the positioning rod 15 restricts the positioning hole, so that the sliding plate 11 is less likely to tilt during the sliding process, and the sliding of the sliding plate 11 is more stable.

[0047] When the sliding plate 11 is pressed down to fix the sliding block 10, by setting a fixing pad 16 on the side wall of the sliding block 10, the contact area between the sliding plate 11 and the sliding block 10 can be made larger, so that the friction between the sliding plate 11 and the sliding block 10 can be made larger, so that the sliding plate 11 can better fix the sliding block 10, and effectively avoid the sliding block 10 from moving after being fixed.

[0048] When the coolant flows into the second liquid guide cavity 7 through the second liquid guide pipe 6, the guide plate 17 can guide the coolant so that the coolant can flow better to the position of the liquid outlet. The guide groove 18 is provided on the surface of the guide plate 17 to achieve a better effect of guiding the coolant.

[0049] When the spinneret 2 sprays the spinning solution to form fiber filaments, when the fiber filaments are rolled up, the anti-wear wheel 19 can reduce the friction between the fiber filaments and the side wall of the mounting hole 9, thereby effectively preventing the fiber filaments from being affected by the friction and causing the fiber filaments to break.

[0050] When the anti-wear wheel 19 guides the fiber filaments, an anti-slip pad 20 is provided on the surface of the anti-wear wheel 19, so that the friction between the fiber filaments and the anti-wear wheel 19 can be greater, so that the anti-wear wheel 19 can rotate better, thereby effectively preventing the anti-wear wheel 19 from being stuck and unable to rotate, resulting in sliding friction between the fiber filaments and the anti-wear wheel 19.

[0051] When the sliding block 10 slides inside the spinneret holder 1, the ball bearings 21 can convert the sliding friction between the sliding block 10 and the spinneret holder 1 into rolling friction, so that the friction between the sliding block 10 and the spinneret holder 1 is smaller, thereby reducing the wear between the sliding block 10 and the spinneret holder 1.

[0052] In the process of installing the spinneret 2 into the mounting hole 9, by providing an anti-slip groove 23 on the surface of the spinneret 2, the contact area between the operator's hand or the installation tool and the spinneret 2 can be larger, thereby reducing the chance of slipping when rotating the spinneret 2, making the installation of the spinneret 2 more convenient.
