Problems solved by technology

However, in some occasions, yarn without twist is required, such as yarn performance testing, etc. However, when the yarn is formed into a package, it already has a certain twist, which can be called natural twist, and its twist value is ≤ 20 twists / meter It is very difficult to remove this twist with the existing textile machinery; for another example, when using carbon fiber as a composite material, the carbon fiber bundle cannot have twist, but sometimes the carbon fiber bundle will also produce natural twist when it is wound into a package. Twisting, this will bring great inconvenience to the follow-up work

Embodiment Construction

[0013] Further describe the present invention below in conjunction with embodiment and accompanying drawing thereof.

[0014] The general functional requirements of the mechanical device for filament untwisting of the present invention are: untwisting the filament packages that need to be untwisted, especially utilizing the natural twist (≤20 twists / meter) that is difficult to untwist by large-scale textile machinery, according to the degree of twist The value can adjust the speed of the two main motors to achieve the purpose of untwisting.

[0015] The mechanical device part of the present invention can generally be divided into a filament untwisting rotary mechanism, a filament unwinding rotary mechanism and a filament traction and length fixing mechanism. The transmission of the filament untwisting rotary mechanism is driven by the motor 9 to the synchronous pulley 10, which is transmitted to the synchronous pulley 5 through the synchronous belt. 8 is rotated by rolling be...

Abstract

The invention relates to a filament twist returning device comprising machine device and control means. The machine device comprises a frame and a filament twist returning rotating mechanism, a filament unwinding rotating mechanism and a filament traction and length determining mechanism installed on the frame; the control means comprises: a touch-screen, a PLC controlled frequency converter and a motor. The twist returning device of the invention can perform the twist returning of filament, mainly solves the problems of difficulty for returning the natural twist (<=20 twists / meter) of filament in large-scale weaving machine, and achieves the advantages of stable running, accurate control, low noise and convenient operation.

Description

technical field [0001] The invention relates to filament untwisting technology, in particular to a technology for untwisting filaments with existing twists according to production requirements. The international patent classification number is proposed to be Int.C1 7 G01M1 / 04. Background technique [0002] In the textile industry, in order to improve the yarn strength, the yarn is usually twisted. The twist direction of the yarn can be divided into S twist and Z twist. After twisting, the twist direction of the yarn tends from the lower right corner to the upper left corner, oblique The middle part of "S" is called S twist or hand twist; the twist direction of the yarn is from the lower left corner to the upper right corner, and the direction of inclination is consistent with the middle part of "Z" is called Z twist or backhand twist. The two-for-one twister in textile machinery completes this process, and the twisting technology is basically mature in the textile industr...
