Problems solved by technology

Disclosed in CN101899734A is a processing device and method for polyester and viscose blended yarns with a binary structure. It adopts front and middle rollers to set multiple yarn passages, and rear rollers to set V-shaped collectors to realize yarn blending. And this technology can solve the problem of uncontrollable fiber mixing in the prior art
[0003] In the prior art, when the ring spinning method is used for blending, there are often uneven mixing of different types of yarns, or improper mixing ratios cause defects in performance

Embodiment 1

[0051] Such as Figure 1-3 As shown, a device for blending and color mixing based on three roving coupling drafting and twisting systems, including a drafting and twisting system, the drafting and twisting system is composed of a rear roller group and a front roller group, and the rear roller group includes Combined rear top roller 4 and combined rear roller 5, the front roller set includes front top roller 6 and front roller 7; combined rear roller 5 is made up of rings with three rotational degrees of freedom; the ring with three rotational degrees of freedom The ring is composed of a first ring 8 , a second ring 9 and a third ring 10 which rotate independently of each other.

[0052] The first ring 8, the second ring 9 and the third ring 10 are respectively driven by three different servo motors. The first ring 8, the second ring 9 and the third ring 10 are sequentially sleeved on the same mandrel, and the second ring 9 is fixedly connected to the mandrel by pins, keys or ...

Embodiment 2

[0065] Embodiment 2 structure is basically the same as Embodiment 1, and its difference is:

[0066] Such as Figure 8 As shown, in order to control the front and rear rollers and the rings more accurately, this embodiment uses a programmable controller to control the spindle speed through frequency converters, main motors, and mechanical transmissions in the form of chains, toothed belts, or V-belts. Control; the programmable controller sequentially controls the first ring of the rear roller through the driver 3, the auxiliary motor 3 and the mechanical transmission in the form of chain, toothed belt or V-belt; through the driver 4, the auxiliary motor 4 and the chain in sequence The mechanical transmission in the form of a toothed belt or a V-belt controls the second ring of the rear roller; the mechanical transmission in the form of a drive 5, an auxiliary motor 5 and a chain, a toothed belt or a V-belt controls the second ring of the rear roller in sequence. Three rings f...

Abstract

The invention provides a blending and color mixing device and method based on a three-roving coupling drafting twisting system. The device comprises a drafting and twisting system composed of a rear roller group and a front roller group; the rear roller group comprises a rear stripping roller and a combined roller, and the front roller group comprises a front stripping roller and a front roller. The rear roller group is a combined roller which has three rotation freedom degrees and which is composed of coating three segments of rings with equal outside diameters on one spindle sequentially. The mixing ratio (or the color mixing ratio of roving with different colors) of rovings with different components and operation as required on distributed length on the rovings can be realized by independent control on each part of a drafting mechanism with three freedom degrees, technology is creative, and width of products is increased.

Description

technical field [0001] The invention relates to a device and method for realizing blending and color mixing based on a three-roving coupling drafting and twisting system. Background technique [0002] Ring spinning is one of the most widely used and most versatile spinning methods on the market today. In the prior art, the ring spinning of composite yarn is usually realized by setting different yarns between the front, middle and rear rollers of the drafting and twisting process, such as CN102787411A, a front-type left and right displacement overfeeding composite spinning device and process Through the rotation of the front roller, the bridging roller, the speed regulating roller and the overfeed roller are frictionally driven to overfeed the filament bundle or yarn in the outer shaft system to the front of the front roller, and gather and twist with the output short fiber strands to form a double group part overfeed composite yarn. CN102704124A discloses a three-axis comp...
