Background

The working principle of the twisting disc of the twisting machine is shown in figure 10, the yarn to be twisted is led out from a static protofilament bobbin 3, penetrates into a tension controller through the top end 2 of a spindle tension controller, is adjusted in tension through a tension adjusting steel liner 4, penetrates through a coupling porcelain 5 to change the yarn direction, is led out from a transverse yarn storage opening on a yarn storage disc 7, is wrapped with a certain yarn on the circumference, is thrown out along a twisting disc 6 to form a rotary air ring, is finally collected and led out at a yarn guide porcelain 1, and is wound into a finished product package by a winding mechanism. The bottom of the twisting disk in the prior art is in an arc-shaped convex structure, as shown in fig. 6 and 7, and the problem is that the yarn is influenced by tension during twisting, and the pq section of the yarn swings between the ab section and the cd section in fig. 7. The longer distance of the pq section causes strength loss and hairiness defects to the yarn, and influences the quality of the yarn. Chinese patent document CN201620381874.0 discloses a twisting disk of a two-for-one twister, which provides a twisting disk structure for preventing yarns from being cut off when passing through the twisting disk, and a yarn anti-damage retaining ring is added on the upper side of the outward expansion part of the twisting disk. Although the twisting disk with the structure can prevent the yarn from being cut or cut when passing through the twisting disk, the twisting disk provided with the anti-damage retainer ring can increase the processing and manufacturing cost of the twisting disk component of the twisting machine.

In the figure: yarn guide porcelain 1, spindle tension controller 2, raw silk tube 3, tension adjusting steel liner 4, coupling porcelain 5, twisting disc 6' of the prior art, fixed orifices 61, groove portion 62, bellying 63, horizontal segment 631, arc segment 632, yarn storage disc 7, motor 8, yarn 9, fixed orifices to bellying length L1, bellying length L2, yarn contact spiral curve initial arc ab, yarn contact spiral curve termination arc cd, yarn contact spiral curve current arc length pq.

Detailed Description

As can be seen from the prior art, referring to fig. 7-9, the prior art fixing hole to boss length L1 ' is less than the boss length L2 ', and the contact arc length of the yarn 9 with the prior art twisting disk 6 ' is: a yarn contact spiral curve initial arc length a 'b', a yarn contact spiral curve termination arc length c'd', a yarn contact spiral curve current arc length p 'q', and the yarn contact spiral curve current arc length p 'q' is changed between the yarn contact spiral curve initial arc length a 'b' and the yarn contact spiral curve termination arc length c'd' according to the change of the tension. And arc length a 'b' < p 'q' < c'd'. Because the length of the boss L2 ' is arcuate, the yarn contacts the full length of the boss L2 ' throughout the yarn's initiation, balloon formation, shrink balloon, etc. twist. Thereby easily causing a loss of yarn strength and a yarn hairiness defect.

As shown in fig. 1 to 3, in a twisting disk of a twisting machine, a groove portion 62 and a projection portion 63 are provided at the bottom of the twisting disk 6, and a plurality of fixing holes 61 are provided in the groove portion 62, and a length L1 from the fixing hole 61 to the projection portion is longer than a length L2 of the projection portion in the radial direction of the twisting disk 6. With the structure, the friction length between the yarn 9 and the twisting disc 6 is reduced, so that the strength loss of the yarn during twisting is reduced, the defect of yarn hairiness is reduced, and the quality of the yarn is improved.

Preferably, as shown in fig. 1, the length L1 from the fixing hole 61 to the protruding part refers to the horizontal projection length from the axis of the fixing hole 61 to the inner edge of the protruding part 63 along the radius direction of the twisting disk 6. Preferably, as shown in fig. 1, the length L2 of the protruding portion refers to the length of the horizontal projection from the inner edge to the outer edge of the protruding portion 63 along the radius direction of the twisting disk 6. Under the same diameter, the utility model discloses obtain compare shorter contact length with the yarn with prior art. That is, as shown in fig. 3-5 and 7-9, under the premise that the diameters of the twisting disks are the same, the initial arc length ab of the yarn contact spiral curve is less than the arc length a 'b' of the prior art, the ending arc length cd of the yarn contact spiral curve is less than the arc length c'd' of the prior art, and the current arc length pq of the yarn contact spiral curve is less than the arc length p 'q' of the prior art.

Preferably, as shown in fig. 2, the protruding portion 63 includes a horizontal segment 631 along the radius direction of the twisting disk 6 and an arc segment 632, and the horizontal segment 631 is located at a side close to the groove portion 62. With this structure, there is a difference in the contact position of the yarn 9 with the projection 63 at each stage of the yarn twisting, thereby further reducing the contact length with the yarn. For example, at the initial balloon forming stage, yarn 9 has a greater friction with horizontal segment 631 and little contact, i.e., little friction, with arc segment 632 due to the lower yarn tension. After the yarn 9 forms the balloon, the yarn 9 rubs more with the arc 632 and less with the horizontal 631 due to the tension.

Preferably, as shown in fig. 2, the horizontal plane projection length of the horizontal segment 631 along the radius direction of the twisting disk 6 is greater than the horizontal plane projection length of the arc segment 632 along the radius direction of the twisting disk 6.

Preferably, as shown in fig. 2, the edge of the arc 632 is perpendicular to the horizontal plane. Due to the structure, the yarn 9 cannot be contacted with the edge of the twisting disc 6, namely the edge of the arc-shaped segment 632, under the influence of the shape of the air ring, so that the breakage accident of the yarn 9 is avoided.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and should not be considered as limitations of the present invention, and the protection scope of the present invention should be defined by the technical solutions described in the claims, and includes equivalent alternatives of technical features in the technical solutions described in the claims. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
