Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fiber collecting device for collecting spun fibers discharged from paper thread holes of a rotating paper thread plate by a rotary spinning method.

Paper yarn methods using raw materials that can be used as molten paper yarn include the drawn edge yarn method, in which the molten raw material is extruded through a spinning hole in a weaving cylinder, and the resulting yarn is drawn, and the molten raw material is extruded through a spinning hole in a paper yarn plate that rotates at high speed. There is a rotating paper thread method that uses centrifugal force to discharge paper.

The stretched paper yarn method can provide fibers with high strength and high elasticity by applying sufficient stretching.

On the other hand, the rotating paper thread method has the characteristics of high strength and
Although it cannot be expected to produce highly elastic fibers, it has great advantages in that it does not require advanced drawing technology, the blind pupils are simpler than those for the draw-spinning method, and Tsurumi can be mass-produced. Fibers used for materials such as heat insulating materials, non-woven fabrics, and sliding parts do not require much strength and elasticity, so improvements to the rotating paper yarn method are desired as a paper yarn method for obtaining fibers for such uses. . The secondary fiber collecting means in the rotary spinning method collects the spun yarn by moving a ring-shaped rotating receiver that is coaxial with the rotating paper yarn plate and rotates in the same direction or in the opposite direction as the grain plate. It is something that is collected and continuously honored. When this means is used, the collection is carried out around the entire circumference of the rotating thread tray, so the receiver inevitably becomes larger. The present invention provides a rotary yarn fiber collection device that is smaller in size and simpler in structure than conventional devices.

In the present invention, a case is provided which includes a fixed disk that shields the lower side of the rotating spinning plate and a fixed outer circumferential wall that is formed around the outer periphery of the fixed disk and surrounds the rotating thread removal plate.

The spun threads discharged from the spinning holes of the rotating spinning plate by centrifugal force are rotated along the outer peripheral wall in the same D shape as the paper thread plate and in the same direction by the airflow generated inside the case by the rotation of the paper thread plate. move. The outer peripheral wall is provided with a fiber collection member that rotates continuously across the outer peripheral wall from inside the case to outside the case and into the case. is constructed. Therefore, the fiber collecting member provided at only one location on the outer circumferential wall can sufficiently perform the bridging action. Of course, they may be provided at multiple locations. In addition, the orange collection member may be rotated in conjunction with the paper thread plate. As described above, in the present invention, the vertical bridges on the side of the grade yarn are not formed all around the grade yarn plate, but on a part of the grove of the spinning plate, so that it is possible to downsize and simplify the apparatus.

Next, the present invention will be explained with reference to illustrated embodiments. Reference numeral 1 denotes a rotating paper yarn tray, which has a raw material supply port la at the center of the upper part and a plurality of spinning holes lb at the outer circumference, and is driven to rotate at high speed via a drive shaft 2 by a motor (not shown), The yarn 3 is drawn out in a spiral radial manner from the yarn hole lb by centrifugal force.

The lower part of the thread plate 1 is covered by a generally circular disk 5 having a protruding portion 5a in a part thereof, and this disk 5 is supported and fixed by a fixing member (not shown). An outer circumferential wall 6 is provided on the outer periphery of the disk 5 so as to surround the paper thread plate 1, and the fixed disk 5 and the fixed outer circumferential wall 6 constitute a case 4 in which the thread plate 1 is arranged. . A spinal column 7 is provided on the side of the case 4 in the vicinity of the protrusion 5a, and a bearing guide member 8 is fixed to the upper end of the spinal column 7.

A support plate 9 is fixed to the upper end of the bearing guide member 8, on which a motor 0 is supported, and the motor 10 rotates a pinion 11. A circular gear ring 13 is held in the bearing guide section 8 via a bearing 12 and rotates while meshing with the pinion 11.
A circular rotating plate 14 is provided on the lower surface of the gear ring 13.
is fixed, and a large number of bush fiber collection arms 15 are attached downwardly to the outer periphery at equal intervals. As a result, when the motor 10 rotates, each collection arm 15 rotates together with the rotary plate 14, so that one half of the collection arm 15 runs inside the case 4 and the other half runs around the outside of the case 4 so as to cross the outer peripheral wall 5. Note that the outer peripheral wall 5 is provided with a gate 6a that allows the collection arm 15 to operate. Next, the operation will be explained.

The paper thread plate 1 and the knee collection arm 15 are rotated in the same direction. In the yarn tray 1, a V is supplied inside from the raw material supply V supply port la.
The supplied molten raw material becomes thread 3 by centrifugal force and is ejected from the paper thread hole lb in a spiral radial manner. The yarn 3 is rotated along the outer peripheral wall 6 in the same direction as the spinning tray 1 due to the airflow generated inside the case 1 due to the rotation of the thread removal tray 1.
The fibers arrive at the fiber collection arm 15. This arm 15 rotates in the same direction as the yarn collecting plate 1, that is, in the direction opposite to the movement of the yarn 3, and the yarn 3 is entangled and collected by the collection arm 15, and the rotation of the collection arm 15 is carried out of Case 4 by The yarn 3 is then removed from the collecting arm 15 by means such as air blowing. In this embodiment, an arm is used as a material for collecting the threads 3, but the arm is not limited to this, and any shape that allows the threads 3 to be entangled may be used. As explained above, the rotary spinning Reisen Miscellaneous Collection Ryokan of the present invention is provided with a case around the thread extraction plate that guides and moves the paper thread fibers in the rotational direction of the spinning plate, and a part of this case has a This system is equipped with a fiber collecting member that catches the spinning sickle waste that is produced in the spinning dish, and there is no need to provide a bottle collecting member that rotates around the entire circumference of the spinning dish unlike a secondary kettle, making the device lightweight, compact, and simple in structure. can be taken as a thing.
