Description

Intermingle apparatus of compound fiber gauze used in false twisting machine for industry

The present invention relates to a synthetic fiber yarn entanglement apparatus of an industrial combustor, and more particularly, to spin and stretch an industrial synthetic fiber represented by a polyester yarn or a polyamide yarn, and to entangle the fiber yarn on a combustor by using compressed air. It is possible to entangle the fiber yarn continuously without stopping the combustor by simple operation of the nozzle.In particular, it is possible to provide a certain number of entanglements per unit length by using compressed air when weaving the fiber yarn (filament yarn). It relates to a synthetic fiber yarn entanglement apparatus of a combustor.

In general, synthetic fiber multifilament yarns cause friction with friction agents such as yarn guides or rollers during post-processing, resulting in loops, wool or cutting, resulting in poor process workability and deterioration of product quality. Is a known fact.

Conventional twisting method for improving the convergence of synthetic fibers has been replaced by the air entanglement method due to the complexity of the process and the high manufacturing cost.

However, since the air entanglement method uses compressed air, it has been limited in the air pressure and the number of entanglements (pieces / m). Because the air pressure and the number of entanglements are in proportional relationship, if compressed air of excessive pressure is used in order to increase the number of entanglements, problems such as truncation may occur, or rather, the convergence may be poor. Therefore, the effective device to entangle the number of entanglement to 5 / m or more or the air pressure of more than 3Kg / ㎠ has not been put to practical use.

In order to solve the above problems, it is known that the Republic of Korea Patent Publication No. 96-12819 "Manufacturing method and apparatus for industrial synthetic fiber entangled yarn".

Here, in the case of industrial synthetic fiber multifilament yarn having single yarn fineness of 4.5 denier or more, after melt spinning, firstly tanning and multi-stretching the air, it is the highest temperature (220 ~ 240 ° C) among the rollers and room temperature. The method of entanglement is characterized by the second tanning of yarns with the Goderoler and the immediate air communication.

The air pressure is limited to 2.0 to 4.0 Kg / cm 2 and the number of entanglements is 8 to 12 / m.

In addition, in the case-type air entanglement device which is opened and closed by a cover having a see-through window and a close contact, an air entanglement device is provided, in which an emulsion treatment device and an air entanglement device are installed in series. The apparatus is limited to a jet tanning apparatus connected to a metering pump, and the nozzle of the entanglement apparatus is limited to a pentagonal form.

By the way, when the short circuit of the fiber yarn occurs, such a device has a disadvantage in that the continuity of the work is deteriorated because the short circuit of the fiber yarn must be checked through the sight glass, and then the combustor is stopped and then the cover is opened to perform a joint operation.

On the other hand, the fiber entanglement device used in other countries uses compressed air with a cock or forms a slide type for continuous combustion, but this is because the product price increases due to the increase in parts according to its composition. In addition, the work efficiency is significantly reduced while the short life.

Accordingly, an object of the present invention is to adopt a relatively simple configuration, but can be performed by the simple operation of the fiber yarn without the stop of the combustor, and in particular, the industrial that can facilitate the entanglement of the fiber yarn by preventing the loss of compressed air in advance. It is to provide a synthetic fiber yarn entanglement apparatus of a combustor.

As can be seen in these figures, the entanglement device 10 according to the present invention includes a guide control 21, a lower body 20 to which the guide control is assembled, and an upper part of the lower body 20. The upper body 40 is provided.

Guide slots 22 and 22a are formed at both sides of the guide control 21, respectively, and the guide slots 22 and 22a are rollers 23 for guiding fiber yarns and rollers for guiding yarns (fiber yarns). Guide pins 24 and 24a connecting the 23a are respectively positioned and assembled by bolts 50, and the rollers 23 and 23a are moved up and down from the guide holes 22 and 22a to vary their heights. can do. Here, the rollers (23) (23a) is formed of a high-strength ceramic to prevent deformation by the fiber yarns and entangled yarns to be conveyed at high speed.

Meanwhile, between the roller 23 and the roller 23a installed in the guide control 21, the lower body 20 is assembled by the bolts 50, and the lower body 20 has a guide path 25 recessed from the surface. The guide hole 26 is formed in the center of the guide path to guide the compressed air upwards.

The slide push 27 is inserted into the guide path 25 of the lower body 20 to be moved forward and backward, and the slide push 27 coincides with the guide hole 26 formed in the lower body 20 on the same axis. A through hole 28 is formed.

The upper body 40 is fixed to the rear region of the slide push 27 by the bolt 50, the slide 41 is located on the lower surface of the upper body 40 is in close contact with the spring slide 30 of the compressed air Prevent loss. Here, the spring slide 30 and the slide 41 are also formed of high strength ceramic to prevent deformation by the fiber yarn.

In the upper portion of the lower body 20, a guide groove 31 formed in a V-shape along the horizontal direction and a spring slide 30 formed with a nozzle hole 32 are assembled by screws 51. The nozzle hole 32 formed in the center entangles the fiber yarn conveyed by the compressed air by guiding the compressed air in correspondence with the guide hole 26 and the through hole 28 on the same axis. In particular, the both ends of the guide groove 31 formed in the V-shape to eliminate the angle to prevent short circuit of the fiber yarn and interlacing yarn.

In addition, the upper body 40 has a spring insertion groove 45 formed of at least one or more so as to install a spring 43 and the pressure-sensitive pin 44 for the slide 41 in close contact with the surface of the spring slide 30 After the spring 43 is inserted into the spring insertion groove 45, the opening of the spring insertion groove 45 is fixed by the hexagon wrench bolts 52 so that the exchange and adhesion strength of the spring can be adjusted.

The entanglement device 10 according to the present invention configured as described above is used to produce entangled yarns by using compressed air on the combustor after spinning and stretching the industrial synthetic fibers represented by polyester yarns or polyamide yarns.

As shown in FIG. 1, the fiber yarn guided to each of the oil supply rollers 60 installed up and down is entangled and transferred through the overfeed roller 61.

First, as shown in FIG. 4, the fiber yarn is guided to the roller 23, drawn into the guide groove 31 formed in the spring slide 30, and then guided to the roller 23a side. After doing so, when the slide push 27 is pulled forward, the upper body 40 is pulled toward the lower body 20 as shown in FIG. 5. Therefore, the fiber yarn located in the guide groove 31 is entangled by the compressed air guided to the guide hole 26 and the through hole 28, the nozzle hole 32 formed in the lower body 20.

Here, as illustrated in FIGS. 4 and 5, the upper body 40 is separated from the surface of the spring slide 30 by moving the slide push 27 back and forth to guide holes formed in the lower body 20. This is because the compressed air injected into the nozzle hole 32 can be blocked and controlled by allowing the through hole 28 formed in the slide push 27 to be opened and closed.

In other words, blocking the compressed air injected into the nozzle hole 32 is because it can control the degree of entanglement of the fiber yarn and also because the fiber is transported at a high speed on the combustor, when the filament fiber yarn is shorted during the fiber processing during the first introduction of the combustor This is because after the nozzle hole 32 is blocked without stopping, the continuity of the work can be given only by a simple joint operation.

Referring to the blocking of the nozzle hole 32 in detail, first, the position of the upper body 40 in the state where the fiber yarn is inserted into the guide groove 31 is the surface of the spring slide 30 screw-assembled to the lower body 20 You will encounter At this time, the slide 41 supported by the spring 43 and the push pin 44 at the lower portion of the upper body 40 is in contact with the surface of the spring slide 30 to maintain airtight even when used for a long time under strong air pressure. It prevents damage of filament yarn by preventing loss of compressed air. In addition, the airtightness of the contact surface between the spring slide 30 and the slide 41 adjusts the holding force of the spring 43 by tightening and loosening the hexagon wrench bolt 52 installed on the upper body 40, in particular, Replacement of the spring 43 is easy.

When the fiber yarn is shorted by compressed air in the state of entanglement, the slide push 27 is pushed backward. In this case, the upper body 40 is separated from the spring slide 30 installed in the lower body 20, and the slide 41 is also separated.

As such, the spring slide 30 is exposed by the upper body 40 separated from the lower body 20, and the nozzle hole 32 is blocked as the slide push 27 moves backward. If the short section of the yarn is jointed, the joint can be easily worked without stopping the combustor.

Then, after the completion of the joint operation, if the slide push 27 is moved forward again, the upper body 40 is moved forward and the slide 41 is in contact with the surface of the spring slide 30 to prevent the loss of compressed air. This prevents the fiber yarns from being entangled by compressed air.

On the other hand, the roller 23, 23a, the slide 41 and the spring slide 30 forming the entanglement device 10 according to the present invention is formed of a high-strength ceramic roller 23 (23a) according to the high-speed transfer of fiber yarn ), The slide 41 and the spring slide 30 can be prevented in advance, and in particular, the short edges of both ends of the guide groove 31 formed in the V-shape can be eliminated and the rounded ends can be formed to prevent short circuit of the fiber yarn. have.

As described above, according to the present invention, there is provided a synthetic fiber yarn entanglement apparatus of an industrial combustor which can easily perform the drawing and joining operation of the fiber without stopping the combustor when the fiber is drawn in due to the short-circuit of the fiber yarn being conveyed at high speed. do.
