Description

A segment color core-spun yarn device

technical field

The utility model relates to the new technology field of spinning, in particular to a segment-color core-spun yarn device. the

Background technique

Compact spinning is a new type of spinning technology that is spun on an improved ring spinning frame. It improves the yarn quality by adding a fiber condensation area before the ring spinning frame traction device. Compared with traditional mesh ring compact spinning, roller compact spinning has certain advantages in compound spinning such as core yarn. The core-spun yarn is a yarn made of synthetic fiber filaments with good strength and elasticity as the core yarn, and short fibers such as outsourcing cotton, wool, and viscose fibers are twisted and spun together. It has both filament core yarn and outsourcing Excellent performance of short fiber. Segment colored yarn is another new type of composite yarn. It is a new type of colored spun yarn produced by appropriate transformation on the ring spinning machine in recent years. It has a new style of multi-color combination, which is different from the general Fancy yarns and segmented colored yarns present irregular and unique flower and color effects. In the axial direction of the yarn, there are not only thickness changes, but also fancy colors that appear alternately in discontinuous distribution. At present, a series of progress has been made in the production of core-spun yarn and segment-colored yarn, but the combination of the two has not yet been used. Aiming at this, the utility model provides a segment color core-spun yarn device. The device uses three servo motors to individually control the three-row rollers to achieve independent regulation of the speed of the three-row rollers, and the front roller uses a narrow-groove hollow roller with a diameter of 50mm to achieve fiber accumulation before twisting and improve yarn quality; During spinning, the white roving is fed by the rear roller through the bell mouth, the colored roving 1 and the colored roving 2 are fed by the middle roller through the yarn guide groove with two guide grooves, and the core yarn is fed by the core yarn feeding device through the front roller. Top roller feed.

Contents of the invention

The technical problem to be solved by the utility model is to provide a core-spun yarn production device with segment color effect.

In order to solve the above problems, the technical solution adopted by the utility model is that the ring spinning frame adopts a three-roller drafting mechanism, including a rear drafting roller pair composed of a rear roller and a rear top roller, and a middle roller pair composed of a middle roller and a middle top roller. The drafting roller pair is a front drafting roller pair composed of a narrow-groove hollow front roller with a diameter of 50mm, a front top roller, and an anti-twist top roller. The feeding material includes a white roving and two colored rovings: colored roving 1 And colored roving 2, and elastic core yarn.

In the above technical solution, the three-column rollers are controlled by three independent servo systems. A bell mouth feeding device is installed on the upper part of the back roller. During spinning, the white roving is fed from the back roller through the bell mouth; At the same time, the colored roving 1 and the colored roving 2 are fed by the middle roller through the yarn guide groove containing two yarn guide slots; the core yarn feeding device is installed on the upper part of the cradle and the lower part of the roving frame. When spinning, the core yarn Feed by front top roller.

In the above technical solution, the front roller is a narrow grooved steel hollow roller with a diameter of 50 mm, which contains a suction component inside, and the front top roller forms the front nip, and the anti-twisting top roller forms the twist-resistance nip, and the front nip There is a fiber gathering area between the mouth and the twist-stopping jaw, and an airflow guide plate device that can strengthen fiber cohesion is installed between the front jaw and the twist-stopping jaw.

Further, the colored roving 1 and the colored roving 2 fed by the middle roller can be the same color or different colors.

After adopting the above structure, the production of core-spun yarn with segment color effect can be realized, the appearance style of the yarn can be improved, and the added value of the yarn can be increased. At the same time, since two rovings are fed through the middle roller at the same time, the covering effect of the core yarn can be effectively improved. .

Detailed ways

As shown in Figure 1, a four-roller section color core-spun yarn device includes a rear draft roller pair consisting of a rear roller 2 and a rear top roller 10, and a middle draft roller consisting of a middle roller 3 and a middle top roller 9. Yes, a front drafting roller pair consisting of a narrow-groove hollow front roller 4 with a diameter of 50mm, a front top roller 7, and a twist-resistant top roller 8. Among them, the front roller is a narrow-groove steel hollow roller with a diameter of 50mm, which contains a suction assembly 6 inside. The twisting jaw, the fiber accumulation area between the front jaw and the twist resistance jaw is equipped with an airflow guide plate device 5 that can strengthen fiber aggregation.

As shown in Figures 1 and 2, the three-row roller rear roller 2, middle roller 3 and front roller 4 respectively adopt four independent servo systems 21, 22 and 23 and are controlled by a programmable logic controller 24; A bell mouth feeding device 15 is installed, during spinning, the white roving 1 is fed by the back roller 2 through the bell mouth 15; a yarn guide groove device 14 containing two yarn guide slots is installed on the upper part of the middle roller 3, During spinning, the colored roving 12 and the colored roving 13 are fed by the middle roller 3 through the yarn guide groove 14 containing two yarn guide notches; a core yarn feeding device is installed on the upper part of the cradle and the lower part of the roving frame, and the core yarn The feeding device includes a pair of active feeding rollers 17 and wire guide wheels 18. During spinning, the core yarn 16 is fed by the front top roller 7.

During spinning, the white roving 1 is continuously fed by the back roller 2 through the bell mouth 15, and the colored roving 112 and the colored roving 213 are intermittently fed by the middle roller 3 through the yarn guide groove 14 containing two yarn guide notches. When the rear roller 2 is controlled by the servo control system 21 to rotate and feed the white roving 1 at a normal speed _V1 , the middle roller 3 is controlled by the servo control system ₂₁ to control the colored roving 112 and The colored roving 213 is fed through the yarn guide groove 14 that contains two yarn guide notches, and is spun into a colored yarn section yarn; when the middle roller 3 stops rotating, the rear roller 2 is controlled by the servo control system 21 to accelerate V ₃ to feed the white yarn The roving 1 is spun into a white segment yarn, wherein the speed V ₃ is controlled by the segment color magnification. The core yarn 16 is directly fed into the front top roller 7 by a pair of positive feeding rollers 17 through the wire guide wheel 18, and then merges with the main roving after drafting at the entrance of the front roller 4, and passes through the narrow groove hollow front roller 4. The yarn is twisted into yarn after being gathered by the negative pressure airflow, and then wound on the bobbin 20 through the yarn guide hook 19 to complete the spinning process.
