本発明は回転紡糸法によりピッチや樹脂などの紡糸ロエ
能な溶融原料を紡糸するための回転紡糸回に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary spinning machine for spinning a molten raw material capable of being spun, such as pitch or resin, by a rotary spinning method.
溶融ｉＪ能な原料の紡糸法としては、溶融原料を紡糸筒
の紡糸孔より押し出し、その糸条を延伸する延伸紡糸法
と、溶融原料を高速回転する紡糸皿の紡糸孔より遠心力
を利用して吐出し、繊維状とする回転紡糸法とがある。Spinning methods for molten iJ-capable raw materials include the draw spinning method, in which the molten raw material is extruded through the spinning hole of a spinning tube and the resulting yarn is drawn, and the molten raw material is spun through the spinning hole in a spinning plate, which rotates at high speed, using centrifugal force. There is a rotary spinning method in which the fiber is discharged and made into a fiber.

法として回転紡糸法の＆轡が望まれている。The draw-spinning method can obtain high-strength, high-elastic fibers by applying sufficient drawing. On the other hand, although the rotary spinning method cannot inherently be expected to produce fibers with high strength and high elasticity, it does not require sophisticated drawing technology, and the equipment is simpler than that for the draw-spinning method. Also, it has great advantages from the viewpoint of productivity. Since fibers used for materials such as heat insulating materials and nonwoven fabrics do not require much strength and elasticity, rotary spinning is desired as a spinning method for obtaining fibers for such uses.

同転１蛇される。A rotary spinning plate for carrying out the rotary spinning method has a large number of spinning holes, and heated and melted raw materials are discharged by centrifugal force from the spinning holes that rotate at high speed to become fibers. FIG. 1 shows a rotating spinning dish for spinning molten pitch to obtain carbon fibers, and the spinning hole 10 is O1!11fI of the spinning yarn l11iA'.
j, and the heater 2 is provided facing the bottom surface 12. Incidentally, the spinning plate A' is rotated once by the rotating shaft 3 of the motor.
ところで、この回転紡糸皿Ａ′は紡糸時の高速回転によ

とでは温度差が生じる。紡糸孔１０を形成した紡糸面の
側面において特に冷却の傾向が著しい。By the way, this rotary spinning dish A' is cooled by high-speed rotation during spinning, and a temperature difference occurs between the bottom surface 12 facing the Peter 2 and other parts. The cooling tendency is particularly remarkable on the side surface of the spinning surface where the spinning holes 10 are formed.

かでｔ！なくなるという問題があった。Therefore, in order to wet the raw material during spinning from the spinning hole, it is necessary to heat the spinning surface A/ with the heater 2 more than necessary, which causes the bath melt pitch in the spinning dish to overheat. If the viscosity becomes too high or the raw material deteriorates, and if spinning continues for a long time, the quality of the fiber will deteriorate, and the spinning will not be stable. There was a problem with it disappearing.

たものである。Therefore, the present invention breaks the conventional fixed idea of forming spinning holes on the side surface of the spinning surface, and creates spinning holes on the bottom surface of the spinning surface that faces the heater (when the beater faces the -L curve of Spinning! This solves the above-mentioned problem by providing it on the upper surface.

The spinning surface A is constituted by two upper and lower metal part-1 members 11 and 12. One of the divided members, the -F plate 11, is provided with a raw material feeding port 13 at its upper part. The other member, the lower plate 12, has a flat plate shape, and the inner peripheral surface of the upper plate 11, which corresponds to the bottom surface 12 of the conventional example shown in FIG. It is made of cedar in the direction of matching Theba. A large number of grooves are formed radially at predetermined intervals in the tapered direction of the lower plate 12, and the upper plate 11 and the bottom surface 12
The above-mentioned groove forms a spinning hole 10 by connecting them with a bolt 4. - The above-mentioned threshold can be easily processed by means such as knurling. The cross-sectional shape of the groove can be any suitable shape, such as a semicircle, square, or triangle.

°〜６０°の範囲である。The inclination angle of the spinning holes 10 is not particularly limited. For example, the peripheral edge of the upper plate 11 of the spinning surface A is cylindrical, the outer circumferential surface of the F plate 12 is perpendicular to the lower plate surface, and the spinning holes 10 are formed on this outer circumferential surface.
We can also form a sho that becomes 1ρ. In this case, the direction of the spinning hole 10 is approximately perpendicular to the direction of centrifugal force, but sufficient spinning can be achieved even with this spinning hole. However, the most preferable inclination angle of the spinning hole is 30° with respect to the direction of centrifugal force.
It is in the range of 60°.

ある。According to the rotary spinning aspect of the present invention, since the spinning hole faces the heater, the drop in humidity near the spinning hole is extremely small even during high speed rotation. Therefore, if the molten pitch in the spinning dish is heated with a heater to a temperature suitable for spinning, the pitch will be discharged from the spinning hole at an optimal temperature during spinning. This also eliminates the need to increase the pitch in the spinning pan more than necessary in order to make the temperature of the molten pitch optimal when it is discharged from the spinning hole, and the pitch does not deteriorate. In addition, there will be no waste of power consumption. The 0 F table is the spinning pitch that Invention 4 prepared by adjusting the spinning hole fan degree during high-speed rotation! d'71 shows the results of an experiment comparing the heating conditions for maintaining the appropriate wetness at 330''C for spinning yarn 11 [1 of the conventional example and the example of the present invention.

も最適湿度に保持できる。As described above, according to the present invention, the temperature of the sagging heater plate can be set lower by 80° C., and both the temperature inside the spinning dish and the temperature of the spinning hole can be maintained at optimum humidity.

行なうことができる。In the above example, the heater faces the paper surface of the spinning surface, but for a spinning surface in which the heater is installed above the spinning surface and the raw material pitch is fed from the spinning plate F section under pressure for spinning. Needless to say, the spinning holes are formed on the upper surface of the spinning surface facing the heater. Furthermore, as in the above-mentioned example, the spinning surface may be constituted by a WJ member, and bolts, etc.
If the structure is such that they are joined by means that can remove uJ, it is possible to form a spinning hole by machining a droplet on the shoulder surface of one member, which not only facilitates manufacturing, but also makes it possible to form a spinning hole in the spinning dish and in the spinning hole. Cleaning can be easily done by disassembling the spinning surface.
