It should be noted that, since the carrier tapes 420 have a certain width, under the action of the lead blocks 630 installed between the carrier tapes 420 and the second drafting portion, specifically, the lead blocks 630 are driven by the traction shaft 620 to slide transversely, so that the yarn can be reliably and stably wound layer by layer on each carrier tape 420 to form a winding frame.

In one embodiment, the guide 510 and the traction element 610 are linear bearings.

The guide 510 is used to allow the guide shaft 520 to slide laterally, that is, to allow the guide shaft 520 to slide along the axial direction of the guide 510. Since the guide shaft 520 and the guide 510 frequently rub against each other during the double twisting process of the yarn. Similarly, the traction shaft 620 also slides back and forth along the axial direction of the traction member 610, and frequent friction occurs between the traction shaft 620 and the traction member 610. By providing the guide 510 and the traction member 610 as linear bearing structures, excessive lubrication oil can be prevented from being applied between the guide shaft 520 and the guide 510 and between the traction shaft 620 and the traction member 610, so that the lubrication oil can be prevented from becoming black and dripping after long-term use. Therefore, the yarn can be prevented from being polluted in the double twisting process, and the double twisting processing quality of the yarn is effectively ensured.

As shown in fig. 2, in an embodiment, the guide assembly 500 further includes a guide clamping block 540, the guide clamping block 540 is adjustably disposed on the guide shaft 520, and the guide wheel 530 is rotatably disposed on the guide clamping block 540.

Specifically, the position of the guide clamping block 540 relative to the guide shaft 520 can be adjusted, and the guide wheel 530 is rotatably mounted on the guide clamping block 540 through a bearing, so that the position between the guide clamping block 540 and the guide shaft 520 is adjustable, so that the transverse position of the guide wheel 530 relative to the first drafting assembly is adjustable, and when the guide shaft 520 drives the guide wheel 530 to slide transversely, the yarn is driven to be accurately drafted by the first drafting assembly. Further, the guide wheel 530 is bearing-mounted on the guide clamping block 540 such that the guide wheel 530 can rotate relative to the guide clamping block 540.

As shown in fig. 2 and 4, in one embodiment, the guide clamping block 540 is provided with a sliding groove 541 and a clamping groove 542 which are mutually communicated, the guide shaft 520 is inserted into the sliding groove 541, the guide assembly 500 further includes a clamping screw 550, the clamping screw 550 is inserted into one inner sidewall of the clamping groove 542, and the clamping screw 550 is in threaded connection with the other inner sidewall of the clamping groove 542, and the clamping screw 550 is used for driving the opposite inner sidewalls of the clamping groove 542 to approach each other, so that the inner sidewall of the sliding groove 541 clamps the guide shaft 520.

It should be noted that, the sliding grooves 541 and the guiding shaft 520 are mutually adapted, the clamping grooves 542 are in a slit structure, so that the clamping screws 550 are mounted on the guiding clamping blocks 540, and the clamping screws 550 are utilized to narrow the distance between the clamping grooves 542, so that the sliding grooves 541 are narrowed mutually, and the inner side walls of the sliding grooves 541 clamp and fix the guiding shaft 520, that is, the guiding clamping blocks 540 and the guiding shaft 520 are fixedly mounted in a position-adjustable manner.

As shown in fig. 3, in one embodiment, traction assembly 600 further includes a traction clamp block 640, traction clamp block 640 being adjustably disposed on traction shaft 620, and lead block 630 being disposed on traction clamp block 640.

In this manner, the lead blocks 630 may be adjusted to be precisely aligned with each carrier strip 420.

As shown in fig. 5, in one embodiment, the yarn guiding block 630 is further provided with a yarn guiding groove 632 for guiding the yarn.

It should be noted that, when the wire block 630 is driven by the traction shaft 620 to slide transversely, the yarn is wound on each carrier strip 420 layer by layer as the rotation shaft 410 drives each carrier strip 420 to rotate. In order to reliably guide the yarn, the yarn guiding groove 632 is formed in the yarn guiding block 630, so that the yarn passes through the yarn guiding groove 632, the yarn is limited and guided by the inner side wall of the yarn guiding groove 632, and the yarn is driven to stably wind on each material loading strip 420 along with the transverse sliding of the yarn guiding block 630.
