Description

Technical Field

[0001] The utility model relates to the field of spinning equipment, in particular to a wet spinning equipment. Background Art

[0002] Wet spinning equipment is a machine that forms a fiber-forming polymer solution or melt into a filament. According to different fiber spinning methods, spinning machines are divided into three types: wet spinning machines, melt spinning machines, and dry spinning machines. The characteristics of wet spinning are that the number of spinneret holes is large, but the spinning speed is slow, which is suitable for spinning short fibers. In the process of wet spinning, the spinning solution needs to be prepared first, and the polymer needs to be dissolved in an appropriate solvent to form a uniform spinning solution. This step needs to be carried out in a controlled environment, such as a temperature and humidity control room, to ensure the quality of the solution. Then the prepared spinning solution is loaded into the supply system of the spinning machine, and a thin stream is ejected through the spinneret and enters the coagulation bath to form fibers. The coagulation bath coagulates the ejected thin stream into fibers.

[0003] In the existing wet spinning equipment, since the thin stream ejected from the spinneret is light in weight, the thin stream moves slowly in the coagulation bath. With the continuous spraying of the spinneret, after the thin stream is shaped in the coagulation bath, if it does not move in time, it is easy to cause spinning accumulation and retention in the coagulation bath, affecting the speed of spinning entering the next step and reducing the efficiency of the spinning process.

DETAILED DESCRIPTION

[0022] 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.

[0023] Example: Reference Figure 1-4 A wet spinning device shown in the figure comprises a coagulation bath 1 capable of accommodating spinning movement, a spinning nozzle 2 facing the inner side of the coagulation bath 1, and a first traction roller group 5 arranged outside the coagulation bath 1. The coagulation bath 1 can coagulate the fine flow ejected by the spinning nozzle 2 into fibers. A first guide structure and a second guide structure are arranged on the coagulation bath 1, and the first guide structure and the second guide structure are respectively close to the spinning nozzle 2 and the first traction roller group 5.

[0024] The first guide structure includes a first limiting wheel 8 and a first guide wheel 9 which are arranged in the coagulation bath 1 from top to bottom, and the gap between the first limiting wheel 8 and the first guide wheel 9 is opposite to the discharge port of the spinning nozzle 2. When the spinning nozzle 2 sprays a large number of filaments into the coagulation bath, the first limiting wheel 8 can move the liquid to quickly contact the filaments, thereby improving the efficiency of filament forming. At the same time, the first guide wheel 9 rotates in the opposite direction to the first limiting wheel 8, which ensures the stability of filament forming and can also quickly transfer the filaments sprayed by the spinning nozzle 2, effectively avoiding the filaments from being retained and accumulated under the spinning nozzle 2, and does not affect the continuous spraying of subsequent filaments.

[0025] The second guide structure includes a second limiting wheel 12 and a second guide wheel 13 arranged from top to bottom in the coagulation bath 1. The second limiting wheel 12 and the second guide wheel 13 can rotate synchronously in opposite directions. The second limiting wheel 12 can improve the comprehensiveness of the contact between the water inside the coagulation bath 1 and the spinning. During the rotation process, the second guide wheel 13 is higher than the first limiting wheel 8. Therefore, the moving path of the spinning formed inside the coagulation bath 1 is smoothly inclined upward, and the second guide wheel 13 leads it into the gap between itself and the second limiting wheel 12, and then moves along the inclined moving path until it is led out of the coagulation bath 1 by the first traction roller group 5.

[0026] In this process, the continuity of the spinning movement can be maintained, so that the spinning can be quickly and accurately moved out of the coagulation bath 1, effectively avoiding the accumulation of the spinning inside the coagulation bath 1 again after the spinning passes through the first guide structure, so that the spinning can quickly enter the next process. The efficiency of the spinning movement is improved, and the efficiency of the spinning process is further improved.

[0027] The coagulation bath 1 is provided with a guide plate 16 distributed in an inclined state. The guide plate 16 is located directly below the spinning nozzle 2, and a channel 17 for accommodating the passage of liquid is provided on the surface of the guide plate 16. The lower end of the guide plate 16 is close to the first guide wheel 9. When the spinning nozzle 2 sprays liquid, the spinning dispersion phenomenon caused by the faster speed of the guide plate 16 spinning nozzle 2 can guide the spinning to move smoothly downward. It can be avoided that the lower end of the guide plate 16 is equal to the height of the first guide wheel 9. Therefore, combined with the rotation of the first guide wheel 9, the filaments sprayed by the spinning nozzle 2 can be smoothly transferred, effectively avoiding the phenomenon that the filaments sprayed by the spinning nozzle 2 are retained and accumulated in the coagulation bath 1.

[0028] An extension plate 18 is provided in the coagulation bath 1. The extension plate 18 is located on the opposite side of the first guide wheel 9 and the second guide wheel 13. The extension plate 18 is inclined upward near the end of the second guide wheel 13, and the higher end of the extension plate 18 is at the same height as the second guide wheel 13. The setting of the extension plate 18 has a guiding effect on the spinning in the moving state, and smoothly guides the spinning to the second guide wheel 13. With the continuous rotation of the second guide wheel 13, the spinning can be led out of the coagulation bath 1 along the inclined direction, reducing the obstruction caused by the liquid pressure in the coagulation bath 1 when the spinning is led out of the coagulation bath 1, and improving the smoothness of the spinning movement.

[0029] like Figure 2 As shown, a liquid preparation mechanism 3 is provided outside the coagulation bath 1, and a gas pressure liquid supply structure 4 which can be matched therewith is provided on the liquid preparation mechanism 3, and the spinning nozzle 2 is arranged at the liquid supply outlet end of the gas pressure liquid supply structure 4. The polymer needs to be dissolved in a suitable solvent in the liquid preparation mechanism 3 to form a uniform spinning solution to ensure the quality of the solution.

[0030] like Figure 2 As shown, in order to improve the cleanliness of spinning, a cleaning tank 6 is provided on the side of the coagulation bath tank 1 away from the spinning nozzle 2. The first traction roller group 5 can guide the spinning into the cleaning tank 6. The cleaning tank 6 is provided with a second traction roller group 7 that can pull out the spinning in the tank. After the spinning passes through the cleaning tank 6, it can be pulled out by the second traction roller group 7 and enter the drying equipment until the spinning is concentrated and wound up.

[0031] like Figure 4 As shown, in order to ensure that the first limiting wheel 8 and the first guide wheel 9, and the second limiting wheel 12 and the second guide wheel 13 can rotate in opposite directions, a first follower gear 10 is provided at the end of the first limiting wheel 8 and the first guide wheel 9, and a second follower gear 14 is provided at the end of the second limiting wheel 12 and the second guide wheel 13. Each set of first follower gears 10 and second follower gears 14 distributed from top to bottom are meshed and connected.

[0032] The first follower gear 10 and the second follower gear 14 are respectively provided with power motor 11 and power motor 2 15 which are adapted to their models. When the power motor 11 and the power motor 2 are in operation, they can drive each set of the first follower gear 10 and the second follower gear 14 to rotate in the opposite direction, so as to achieve the purpose of driving the first limiting wheel 8 and the first guide wheel 9, and the second limiting wheel 12 and the second guide wheel 13 to rotate in opposite directions.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
