Problems solved by technology

[0003] At present, the general twisting device only has the function of twisting the yarn, and the effect of avoiding unnecessary intertwining between the yarns is not high enough. The texture of the polyester composite yarn after twisting with the general twisting device is not uniform enough and the strength is low.

Embodiment 1

[0031] Such as figure 1 , figure 2 and image 3 A twisting device for polyester composite fibers shown includes a heating mechanism 5, a cooling mechanism 6, a discharge roller 7 and a winding roller 8 arranged in sequence, and is characterized in that it also includes a coil turntable 2 arranged in sequence , a self-twisting mechanism 3 and a thread-combining cylinder 4, and the output end of the thread-combining cylinder 4 is connected to the input end of the heating mechanism 5, and each of the above-mentioned mechanism components is arranged on a vertical support seat 1,

[0032] The coil rotating disk 3 includes a rotating disk 21 and at least two positioning cylinders 22 (in this embodiment, six positioning cylinders 22 are provided) that are uniformly distributed in a ring and fixed on the upper surface of the rotating disk 21; Twisting mechanism 3 comprises the silk thread limiting turntable 31 and the silk thread self-twisting turntable 32 that are fixed together i...

Embodiment 2

[0040] The difference between this embodiment and Embodiment 1 is that the structure of the line-combining cylinder is as follows: Figure 5 As shown, the threading cylinder 4 includes a conical part and a straight-through pipe part. The inner wall of the conical part is evenly provided with threading grooves 18 corresponding to the positioning cylinder 22 one by one, and the threading grooves 18 are connected to the cone along the generatrix The bottom and the top of the shaped part, and the middle part of the notch of each threading groove 18 is provided with a blocking piece 41; a thin connecting rod 19 is fixed on the threading cylinder 4 between each adjacent two threading grooves 18, The lower end of the thin connecting rod 19 is fixed on the upper end of the second connecting rod 12 . In application, the silk thread is attached to the inner wall of the thread-combining cylinder 4, so that the distance between the threads between the self-twisting mechanism 3 and the thr...

Abstract

The invention discloses a twisting device for polyester composite fibers, which belongs to the field of textile industry equipment, and comprises a silk reel turntable, a self-twisting mechanism and a yarn-combining cylinder arranged in sequence, the silk turntable is used for thread supply, and the self-twisting mechanism includes The thread limiting turntable and the thread self-twisting turntable fixed together in the middle, and the fixed groove plate set outside the silk thread self-twisting disk, the thread limit turntable is provided with through holes corresponding to the positioning cylinder one by one, and the fixed groove plate An annular thread self-twisting gap is formed between the inner surface and the thread self-twisting disc; the thread-combining cylinder is in the shape of an inverted funnel, and the thread-combining cylinder is provided with a second through hole or a threading groove to position the thread; Rod two connects the thread-combining cylinder body, the silk thread self-twisting disk and the silk reel rotating disk as a whole, so that they rotate synchronously under the drive of the motor. The invention has the functions of self-twisting and co-twisting of silk threads at the same time, and can efficiently avoid unnecessary entanglement between silk threads. The polyester composite silk thread after co-twisting has uniform texture and high strength.

Description

technical field [0001] The invention relates to the field of textile industry equipment, in particular to a twisting device for polyester composite fibers. Background technique [0002] Polyester fiber (polyester fiber) is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol, referred to as PET fiber. It was invented in 1941 and is currently the largest variety of synthetic fiber. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery ability. It is strong and durable, anti-wrinkle and non-ironing, and non-sticky. The trade name of polyester fiber is polyester, which is made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions. The obtained fiber-forming high polymer - polyethylene terephthalate (PET)...
