Description

Overtwister for a double buncher twister}

The present invention relates to an overtwisted cover and an overtwist roller structure mounted in a housing of a semi-drilling twister, and more particularly, to provide a torsion to a wire formed by twisting the wheel of the disc inside the housing. By installing the frame cover to open and close on the frame with twist, it prevents the zinc powder from falling off the outer circumference of the wire during over twisting operation, and the bracket cover attached to the bearing part of the over twist is in contact with the bracket. It relates to an over twister of a semi-drilling twister that is formed by a protrusion on the inner peripheral surface of the roller to be fixed between the brackets to prevent the detachment of the roller to minimize the twisted wire defect.

In general, the semi-CHAR is a twister wire of the wire wire is continuously supplied while the disk wheel of the convex shape is rotated on both sides of the cradle for supplying a plurality of wires or strands in the housing.

At this time, the twisted wire passing through the outlet side wheel in the housing is installed at the wire exit side and a plurality of bearing parts are arranged in a staggered manner to form a uniform twisted twisted wire through the zigzag bearing part of the over twist. Torsion is given whenever possible.

As described above, the torsion is applied to the stranded wire drawn out continuously through the semi-charging twisted pair. Referring to the conventional structure of the over-twist based on Figs. 1 and 2 as follows.

First, FIG. 1 is a perspective view of a conventional half-leader twister over twister, FIG. 2 is a plan view of a conventional half-leader twister over twister, and FIG. 3 is a cross-sectional view taken along line A-A of FIG.

As shown in the drawing, the conventional anti-twist twister over twister 1 is rotatably coupled to both frames 2 and includes an overtwist 3 having a plurality of bearings 4 mounted on an upper surface of the rotor plate 3a. It consists of a motor (5) for transmitting a rotational driving force so that the over twist (3) is rotated, and a guide roller (7) coupled to the end side of the support bar (6) extending to one side of the frame (2).

The overtwist (3) is mounted on the upper surface of the square rotating plate (3a) having a circular frame fixing portion (3b) at both ends in a state where a plurality of bearings (4) are staggered with each other and the frame fixing portion (3b) It is made of a structure fixed on the wall of the two frame (2).

In addition, the over-twist (3) is a wire supplied on the cradle equipped with a wire supply bobbin inside the half-lead twister housing housing is twisted between the wires through the rotating disk wheels on both sides of the cradle and withdrawn from the outlet disk wheel Before the stranded wire is totally wound on the winder, a torsion caused by the rotation of the overtwist 3 occurs while passing through a plurality of bearings 4 mounted in the overtwist 3 in a zigzag form.

The guide roller 7 mounted on the free end side of the support bar 6 fixed to one side of the frame 2 serves to guide the transfer of the wire drawn into the overtwist 3 through the frame 2. .

Looking at the conventional bearing structure mounted on the over twist based on Figure 3 As follows.

As shown in Fig. 3, the bearing 4 of the conventional overtwist 3 is fixed to the upper surface of the square rotating plate 3a by a bolt B or the like and the outer peripheral surface of the central axis 4a. The bracket 4b is coupled up and down, and the upper and lower brackets 4b are mounted with the bracket cover 4c enclosed therein and a roller 4d having a wire feed groove 4d 'formed between the bracket covers 4c. to be.

The wire conveyed to the overtwist (3) through the rotating disk wheel of the outlet side of the semi-charging machine is transferred through the wire feed groove (4d ') of the outer peripheral surface of the roller (4d) mounted on the plurality of bearings (4) and the driving force of the motor By twisting the over twist (3) by the twisted wire is made.

In the conventional overtwister 1 having such a structure, since the bracket cover 4c, which is covered on the outer peripheral surface of the bracket 4b of the bearing 54, is not in contact with the upper surface of the bracket 4b, the end of the bracket 4b is pressed. There is a disadvantage in that the braking 4b wears fast because no force is generated.

In addition, when the bracket cover 4c is dislodged during over twisting 3 due to the wear of the bracket 4b, the roller 4d inserted between the two bracket covers 4c is fixed to the rotation of the bearing 4. Thereby, there is a problem in that stranded wire defects or disconnection of stranded wires being transferred between a plurality of bearings 4 are caused by being separated.

In addition, since the conventional overtwist 1 is opened on both frames 2 on which the over twist 3 is mounted, the over twister 1 is connected to the wire surface via the over twist 3. As the zinc powder derailed flows inside the semi-cranked strand housing, it is pointed out that the entire apparatus needs to be cleaned when the stranded wire is cleaned, and the surface of the stranded wire is dirty.

Accordingly, the present invention has been made to solve the above-mentioned disadvantages and problems that are pointed out in the conventional over-twist structure of the semi-twisted twister, disc wires are supplied from the cradle installed in the center portion of the half-twist twister housing, In the over twister to form a constant twist quality on the twisted strand wire while passing through the wire, the bracket cover is mounted to the upper and lower bearings of the frame and the frame cover to be opened and closed to the front of the both sides of the frame with the over twist The contact of the bent part of the bracket prevents the scattering of the zinc powder falling off the wire surface and prevents the roller from being separated from the over-twisted bearing, thereby minimizing stranded wire defect or disconnection.
