Description

Spinning wheel device for twistered Polyethylene thread}

The present invention relates to a spinning wheel device for winding PE twisted yarn, and in particular, to a spinning wheel device for winding PE twisted yarn that can prevent dust, eliminate risk factors, and prevent eccentric rotation.

Twisted yarn refers to yarns of continuous fibers or spun yarns that are twisted or twisted by combining two or more yarns or yarns that are twisted.

In particular, PE yarns made of polyethylene (PE) have many advantages such as high-strength material, application of honeycomb shape, optimum stability, excellent heat resistance, excellent impact resistance, and low price. is widely used in the manufacture of

In the manufacturing process of such a burlap string, PE (polyethylene) resin is put into the machine, a color is mixed with the PE resin, and then the PE resin is extruded and spun. Finally, the spun yarn is twisted into several strands to produce a thick yarn through a twisting process.

On the other hand, the trend of increasing importance of waste treatment and the trend of continuously increasing the amount of waste are coincidentally increasing the demand for sacks for waste treatment.

However, the equipment used in the current process to wind the PE twisted yarn for manufacturing the burlap string, that is, the automatic spinning wheel for the burlap string, is old and has many problems, so it is necessary to improve and replace it through the design of a new machine.

That is, during the process of winding the PE twisted yarn, dust caused by friction is excessively generated, which is harmful to the health of workers and deteriorates durability. 1 is a photograph of a state in which dust is generated due to friction during a process of winding a PE twisted yarn.

In addition, because the tip of the spinning wheel was sharp, industrial accidents always existed. Furthermore, when the center of the wheel is eccentric and rotates, production efficiency is lowered, and there is also a possibility of industrial accidents.

Therefore, in order to respond to the increasing demand for sacking cords for waste disposal and to ensure worker safety, the need to improve the device for winding aged PE twisted yarn, that is, the automatic spinning wheel for sacking cords, has emerged.

Meanwhile, a plurality of radiation frames 101 are formed in a radial shape on the outer circumferential surface of the rotation shaft 100 . Radiation frame 101 is preferably adjusted by a stopper so as to be extensible. It is stable that a plurality of radiation frames 101 extend from the top and rear ends of the outer circumferential surface of the rotation shaft 100, respectively.

In addition, a plurality of rotating square pipes 103 are installed at the end of the radiation frame 101 in the axial direction. Since the rotating square pipe 103 is a pipe, the inside is empty. Therefore, the end of the rotating square pipe 103 is sharp and may threaten the safety of workers.

Also, it is preferable that the first fixing table 405 and the second fixing table 407 fix the first cylinder shaft 404 on the right work table 300 . It must be firmly fixed to prevent eccentric movement, and the rotating shaft 100 can properly rotate while maintaining its center.

Since the hole rubber 222 is made of rubber, it is easily deformable and can be easily inserted into the bracket hole 223 .

6 is a perspective view showing a bracket cap 230 fitted to the Y-bracket 210 provided in the bracket frame 200 in the spinning wheel device for winding the PE twisted yarn (PE) of the present invention.

As shown in FIG. 6, the bracket cap 230 is formed with an upper cap 235 so as to be inserted downward from the top of the Y bracket 210. In addition, extension strips 233 extend downward on both sides, and ends of extension strips 233 are connected to each other by transverse strips 231. Since the bracket cap 230 is also made of rubber, it can be easily fitted into the Y-bracket 210, and it is preferable to be integrally manufactured.

7 is a Y-bracket 210 provided in the bracket frame 200 in the spinning wheel device for winding the PE twisted yarn (PE) of the present invention, the bracket cap 230 and the hole rubber 222 are inserted into the hole bracket 220 It is a perspective view.

As shown in FIG. 7, since the PE twisted yarn (PE) is in contact with the rubber bracket cap 230 and the hole rubber 222 to cause friction, there is little concern about dust.

8 and 9 are exploded perspective and longitudinal sectional views showing the compressed rubber 500 inserted into the end of the rotating square pipe 103 in the spinning wheel device for winding the PE twisted yarn (PE) of the present invention.

8 and 9, the compression rubber expansion part 508 in the form of a rectangular parallelepiped of the compression rubber 500 is inserted into the end of the rotating square pipe 103 until it touches the hemispherical compression rubber head 509. lose It is preferable to manufacture the compression rubber expansion part 508 in a size that closely adheres to the inner surface of the radiation frame 101.

In addition, a compression hole 501 is formed in the center of the compression rubber 500, so that the compression bolt thread 502 is compressed by inserting the compression bolt 510 into the compression hole 501 and turning the compression bolt head 504. The rubber expansion unit 508 is inflated. Therefore, it is good to ensure that the compressed rubber expansion part 508 is firmly fixed to the inner surface of the rotating square pipe 103.

Even if the end of the rotating square pipe 103 collides with a worker while the spinning wheel device rotates by the compressed rubber 500, there is no fear of injury.

10 is a perspective view showing an installation state of an eccentricity sensor 600 for detecting an eccentric motion in a spinning wheel device for winding a PE twisted yarn (PE) of the present invention.

As shown in FIG. 10, the pin 611 of the lever 610 is in contact with the outer circumferential surface of the rotation shaft 100, the lever support 613 is the second fixing table 407, and the eccentric detection device 600 is the third fixing table ( 408) is fixed.

11 is a longitudinal cross-sectional view of an eccentricity sensor 600 for detecting an eccentric motion in a spinning wheel device for winding a PE twisted yarn (PE) of the present invention.

As shown in FIG. 11, the eccentricity sensor 600 is provided on the uppermost surface of the first fixture 405, has a substrate 603 therein, and has an anode 605 and a cathode having different lengths upward of the substrate 603. 606 protrudes.

Preferably, the anode 605 is shorter than the cathode 606, and the anode 605 is electrically connected to the lower surface of the contact portion 615 by a flexible wire 609.

In addition, it is preferable that the cathode 606 is spaced apart from the lower surface of the contact portion 615 at predetermined intervals. Therefore, when the outer circumferential surface of the rotating shaft 100 hits the pin 611 by the eccentric movement, the anode 605, the contact portion 615, and the cathode 606 form a closed circuit according to the principle of the lever 610.

On the other hand, when a closed circuit formed by the anode 605, the contact portion 615, and the cathode 606 is formed on the lower surface of the substrate 603, the power supply unit 607 for supplying current, the anode 605, the contact portion 615, and the When the cathode 606 forms a closed circuit, a speaker 608 that emits sound is preferably provided.

In particular, the height adjustment bolt 620 is threaded through the height adjustment bolt hole 622 to limit the height of the contact portion 615 and extends downward until reaching the upper surface of the contact portion 615 .

Here, by configuring the lever 610 on the side of the pin 611 to be heavier based on the lever support 613, if the height is not limited by the height adjustment bolt 620, the pin 611 is always the height of the rotation shaft 100. It is good to make it touch the outer circumference.

12(a) and 12(b) are perspective views of an eccentricity sensor 600 for detecting an eccentric motion in a spinning wheel device for winding a PE twisted yarn (PE) of the present invention.

On the other hand, the other end is preferably provided with a contact portion 615 that is flat and extends to the height adjustment bolt 620 through the eccentric hole 645 of the eccentricity sensor 600.

As a result, when the rotating shaft 100 rotates eccentrically, the outer circumferential surface of the rotating shaft 100 touches the pin 611, and the contact portion 615, the anode 605, and the cathode 606 form a closed circuit, and the speaker 608 By operating the eccentric rotation, there is an advantageous effect.
