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 sheet 41; the 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 t...

Abstract

The invention discloses a twisting device for polyester composite fiber, and belongs to the field of textile industry equipment. The device includes a silk reel turntable, a self-twisting mechanism and a thread combination cylinder. The silk reel is used for supplying threads, the self-twisting mechanism includes a silk thread limit turntable, a silk thread self-twisting turntable and a fixed trough plate, wherein the middles of the silk thread limit turntable and the silk thread self-twisting turntable are fixed together, and the fixed trough plate sleeves the silk thread self-twisting turntable. The silk thread self-twisting turntable is provided with first through holes corresponding location cylinders one to one, and an annular silk thread self-twisting gap is formed between the innerside face of the fixed trough plate and the silk thread self-twisting turntable. The thread combination cylinder is shaped like an inverted funnel, and the thread combination cylinder is internally provided with second through holes or threading troughs for locating silk threads. First connection rods and second connection rods are used for connecting the thread combination cylinder, the silk thread self-twisting turntable and the silk reel turntable into a whole to make the thread combination cylinder, the silk thread self-twisting turntable and the silk reel turntable rotate synchronously. The device has self-twisting and combination functions of the silk threads, unnecessary entanglement between the silk threads can be efficiently avoided, and the twisted polyester composite silk threads have 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)...
