Embodiment 1

[0030] The utility model provides a front roller non-uniform speed output mechanism for spinning core-spun yarn equipment, including a roller drafting mechanism, a front roller central shaft 1, an additional rotating shaft 2, a driving wheel 6, a driven wheel 7, and a belt 9 gears 8; roller drafting mechanism includes front rollers, middle rollers, rear rollers, counterbore bolts 4, top rubber rollers. The front roller is composed of fixed roller 3 and looper roller 3', and the corresponding upper rubber roller is composed of 5 and 5'.

[0031] The roller 3 is fixedly connected with the central shaft 1 through the counterbore bolt 4; the looper roller 3' loops on the central shaft 1, and is driven by the additional rotating shaft 2, and the shaft 2 drives the looper on the shaft 1 through the gear 8 Roller 3 ', or by driving wheel 6, driven wheel 7, conveyor belt 9 transmissions.

Embodiment 2

[0033] The method for spinning core-spun yarn described in the utility model is based on the equipment described in the utility model (see figure). The method can not only spin long filament / short fiber core-spun yarn, but also can spin short fiber / short fiber core-spun yarn, and has good raw material adaptability. The short fiber described in the utility model can be natural fiber, also can be chemical fiber, and its fiber length can be cotton type fiber, medium long fiber, wool type fiber. The filaments include ordinary chemical fiber filaments, high-performance fiber filaments, and twisted short fiber yarns.

[0034] When spinning filament / short fiber core-spun yarn, the process route is (see figure 2 ): The filament is fed by the nip of the front roller and sent to the looper roller 3 of the front roller ， with top roller B5 ，The long filament is held and output at the surface speed of the looper roller, while the other short fiber strands are fed through the rear roll...

Abstract

The invention provides a front roller unequal-speed output mechanism of equipment for spinning covered yarns and a method for spinning the covered yarns. The front roller unequal-speed output mechanism of equipment for spinning the covered yarn is characterized by comprising a roller traction mechanism, a rotating shaft, an additional rotating shaft, a gear and a transmission system, wherein the roller traction mechanism comprises a front roller, a middle roller, a rear roller, a counter bore bolt and an upper rubber roller; the front roller consists of two rollers and two upper rubber rollers; the front roller corresponds to the upper rubber rollers. The front roller unequal-speed output mechanism has the characteristics of being simple in structure, convenient to transform on an original ring spinning frame, stable in running, convenient to repair, easy to popularize and the like; the method for spinning the covered yarns has the characteristics of good adaptability, wide use range, high covering rate, stable product quality, convenience in operation and the like.

Description

technical field [0001] The invention relates to textile technology, in particular to a front roller non-uniform speed output mechanism of a device for spinning core-spun yarn. Background technique [0002] Core-spun yarn refers to a composite yarn combined by core yarn and sheath yarn. It is characterized by combining outer fiber (sheath yarn) and core yarn, which can give full play to their respective advantages, make up for the shortcomings of both parties, and optimize the yarn. structure and characteristics. At present, the core-spun yarn spun on the ring spinning machine is mainly filament / short fiber core-spun yarn, and the core yarn is generally filament, and the staple fiber is outsourced; there are also opposite designs, but they are less used. After the 1990s, short fiber / short fiber core-spun yarn appeared. This kind of core-spun yarn refers to a core-spun yarn that uses short fiber strands as the core and is spun out of another short fiber. [0003] In 1992, Sa...
