2. Description of the Related Art Conventionally, in the production of chemical fibers for spinning,
The molten petrochemical raw material into the nozzle of a chemical fiber manufacturing machine.
After being blown out at high pressure to form a filament,
Into a strand after coating with oil
It was being wound by a winder.

[0003]

[Problem to be solved by the invention] In the above steps,
In the middle of winding, inside or outside the chemical fiber manufacturing machine
Under the influence of the environment, the yarn breakage phenomenon easily occurs. This
Re is to produce a poor quality of the products of chemical fiber, immediately
The yarn breakage phenomenon was discovered every minute, and the chemical fiber manufacturing machine
Operation must be stopped. In other words, thread breaks
Sensors for sensing and thread cutting equipment
It is an indispensable equipment for the machine.

[0004] The current technology is to detect thread breakage.
To provide a sensor to
If a thread breaks in any of the
Generates control signals by detecting changes in land diameter
Then, the thread cutting device cuts all the filaments.
In general oil coating equipment, the specified number
Have working lines (e.g., 4, 6, 8, etc.)
Filaments coming out of these several working lines are bundled
Then, it is wound up by a rotating bobbin shaft. Strand
If one of them works to match the quality of the
If the line breaks, use the same oil coating device.
All filaments coming out of the working line are cut and
The machine must also be stopped. This allows for quality
It prevents defects. The thread cutting device for each work line includes
Each has its own cutter, which can cause thread breakage.
Control signal, the control personnel receives an oil
Turn off the other power supply of the covering device and adjust. In addition,
Hard cutting cutters can easily spill
It's easy to do. Therefore, to maintain the cutting force, usually
Uses expensive metals such as tungsten as the main material
Have been. This is not only extremely uneconomical
And requires periodic replacement work, which hinders the work.
There was something.

In the process of producing filaments,
Raw material was spouted at high pressure and formed into filaments
Afterwards, it is always cooled by cold air,
Must increase the strength of the
Since the formed filament is extremely thin,
The phenomenon of being blown up occurs by applying. That
Therefore, when coated with oil, the surface of the filament
The phenomenon that it was difficult to evenly cover was likely to occur.
The present invention has been devised to solve these disadvantages.
It is.

3). Also, among the blade mounting sheets (33),
Each part has an internal groove for the thread cutting plate (32) to slide.
It is provided corresponding to the position of the cutting part (321), and one of the inner grooves is provided.
On the side, a sliding groove (33) through which each cutting portion (321) can move.
4) is provided, and the sliding groove (33) of each cutting portion (321) is provided.
The movement of 4) opens and closes each yarn guide hole (333),
The cutting part (321) moves the slide (334) to open and close.
Sometimes, the effect of thread trimming is produced and the thread is cut instantaneously.
Can be.

FIGS. 3 and 4 show the yarn cutting operation.
It is. Close to the thread guide hole (333) of the cutting section (321)
The side that has a sharp angle is designed with a sliding groove (334).
At the portion corresponding to the edge of the cutting portion (321)
Also have a sharp angle design. With this,
When the cutting part (321) cuts the yarn, the cutting part (321)
And the effect of cutting well between the sliding groove (334)
You. FIG. 3 shows that under normal working conditions
Lament (4) is pulled down to the winder
FIG. 4 is a view showing a state, and FIG.
(4) when the thread breakage phenomenon occurs
It is the figure which showed the cutting | disconnection operation | movement of the thread | yarn of a position (3). Shown in FIG.
So that the cut portion (321) moves in the slide groove (334) so that
When moving and cutting the yarn, the edge of the cutting portion (321) and the
And upper blade mounting sheet (331), lower blade mounting sheet
Three sharp edges (a) at the tip of (332)
(B) Cutting is performed according to (c). At this time, Fira
Mention (4) is between 4000 and 6000 centimeters per minute
At the speed of Torr.
The filament (4) drawn toward the cutting part (321)
Is momentarily disconnected. Also, the yarn in the present invention
The cutting plate (32) is provided with a plurality of cutting portions (321).
Because of the multi-blade integrated structure,
The filament (4) can be cut and the spool
Quality can be matched.

Next, a description will be given with reference to FIG. this is,
FIG. 2 is an exploded view of the present invention. As shown in the figure, its structure
Is an oil coating device (2) and a thread cutting device on a frame (1).
(3) is attached, and the oil coating device (2) is adjustable
A functional nozzle mounting sheet (5). Nozzle
The attachment sheet (5) can adjust the angle,
The filament (4) blown to the surface is covered with an oil agent.
To increase the toughness of the yarn.

As shown in FIG . 5 and FIG.
Upper blade mounting sheet (331) inside frame (1)
Blade mounting sheet consisting of a lower blade mounting sheet (332)
Above (33), the angle of the oil coating device (2) can be adjusted
The nozzle mounting sheet (5) is provided.
The attachment sheet (5) has several nozzles (21) attached.
Have been killed. Oil is fed behind each nozzle (21).
Conduits (211) are each extended, and the nozzles (2
Spray an appropriate amount of oil from 1). From nozzle (21)
The injected fluid is pulled down to the winder.
Covers the surface of the filament (4) and increases the toughness of the yarn
You. Furthermore, the nozzle mounting sheet (5) projects on both sides
Part (212), and the protrusion (212) is hook-shaped
