Abstract

The utility model relates to a yarn guiding hook. A V-shaped groove is arranged on the inner walls of the connecting position of a yarn passing channel (2) of a hook body (3) and yarns along the direction of the motion of the yarns, and the bottom of the groove is a circular arced surface. In this way, when the yarns passes through the V-shaped groove, filoplume is gathered by two walls of the groove, the filoplume is wound and gathered on the yarns under the action of the self rotation of the yarns, a secondary twisting is formed, so the utility model has the effect of gathering the filoplume. The utility model is tested, the filoplume of woolen yarns and bast fibre spinning yarns can be reduced more than 20 percents by the utility model, and the filoplume of cotton spinning yarns can reduce the filoplume more than 15 percent.

Description

Twizzle

Affiliated technical field the utility model relates to the twizzle that on the guide plate twist yarn is led that is installed in that uses on the spinning machine.

Background technology has the twizzle that generally uses on the spinning machine at present, and there are the tooth bar that is connected with the guide plate or the bindiny mechanism that takes the shape of the letter U in the rear end, and middle for be wound into the yarn channel of crossing of ring-type in the space by steel wire, the yarn through twisting passed through yarn channel and changes direction of transfer.ZL03238968 is disclosed to be exactly the twizzle that the rear end takes the shape of the letter U.Usually the fiber more than 3mm on the yarn is called filoplume, because the yarn channel aperture excessively of twizzle is generally bigger, so twizzle has the filoplume congregational rate hardly.Can partly assemble filoplume when making yarn pass through twizzle, common way is the aperture that reduced yarn channel, must use the thinner steel wire of diameter as making the twizzle material, its consequence is that the intensity of twizzle reduces, crooked easily, fracture, and under the pressure of yarn, cause chatter to cause yarn tension irregular, easily cause Yarn break.

Summary of the invention is to be solved in the utility model to be the problem that above-mentioned twizzle is assembled the filoplume weak effect.

The utility model is to solve like this: the inwall upper edge yarn movement direction of crossing yarn channel and yarn contact site at twizzle is offered V-shaped groove, and the bottom of groove is an arc surface.Yarn is when the V-shaped groove like this, and two walls of groove are gathered filoplume, reels under the spin effect of yarn and accumulates on the yarn, forms secondary twisting, can play the congregational rate of filoplume.Because the length of filoplume is more than 3mm, the bottom arc diameter of V-shaped groove can play the effect of assembling filoplume in 3mm, and its bottom arc diameter is more little, and congregational rate is obvious more; The bottom arc diameter is too small, and fineness is difficult to guarantee, increases the twisting resistance easily, thereby doubly preferable with the 5-10 of yarn diameter, and through test, to wool spinning, that the bast fibre spinning yarn can reduce filoplume is about more than 20%, it is about more than 15% to reduce filoplume to the cotton spinning yarn.

In order to reduce the twisting resistance of V-shaped groove to yarn, improve the filoplume congregational rate, the width of described V-shaped groove reduces gradually along the yarn movement direction.Because the V-shaped groove import is big, the suffered resistance of yarn is less, though its outlet less than import, makes the resistance of yarn also reduce after filoplume is twisted in V-shaped groove thereupon.

The utility model is being offered the V-shaped groove that passes through for yarn on the yarn channel excessively, can play the effect of assembling filoplume preferably, its effect of assembling filoplume is irrelevant with the pore size of crossing yarn channel, and the wire material diameter of making twizzle can increase to improve its intensity.

Fig. 4 is that the A of Fig. 3 is to structural representation.

Fig. 5 is along B-B line cutaway view among Fig. 3.

Fig. 6 is the utility model working state schematic representation.

The specific embodiment is extremely shown in Figure 5 by Fig. 1, there is the yarn channel [2] excessively of ring-type the utility model twizzle coupler body [3] centre, there is the tooth bar [1] that is connected with the guide plate rear end, cross yarn channel [2] at twizzle and offer V-shaped groove [4] with the inwall upper edge yarn movement direction of yarn contact site, as shown in Figure 3, the bottom of groove is an arc surface, and it is smooth arc surface that the yarn entrance point of V-shaped groove forms set face routinely, advance the yarn resistance to reduce, avoid forming new filoplume.By shown in Figure 4, the width of V-shaped groove [4] reduces gradually along the yarn movement direction.By shown in Figure 5, the degree of depth of V-shaped groove reduces gradually along the yarn movement direction, because filoplume is constantly assembled in the process of advancing, the diameter of yarn also reduces thereupon, and the V-shaped groove rear portion is constantly raised and can be improved the tension force of twizzle to yarn.Yarn [7] through the twisting effect of the V-shaped groove on the twizzle as shown in Figure 6, twizzle coupler body [3] is fixed on the guide plate [6] by adjustment screw [5] by the tooth bar of its rear end among the figure.

Claims

1, a kind of twizzle has the yarn channel [2] excessively that spatially is wound into ring-type on the coupler body [3], it is characterized in that the inwall upper edge yarn movement direction of yarn channel and yarn contact site had V-shaped groove [4], and the bottom of groove [4] is an arc surface.

2, twizzle according to claim 1, the arc surface diameter that it is characterized in that V-shaped groove [4] bottom are 5-10 times of yarn diameter.

3, twizzle according to claim 1 and 2 is characterized in that the width of V-shaped groove reduces gradually along the yarn movement direction.

4, twizzle according to claim 3 is characterized in that the degree of depth of V-shaped groove reduces gradually along the yarn movement direction.
