Eccentric-braking filament feeding device applied to forced internal-external transfer type composite spinning

Abstract

The invention relates to an eccentric-braking filament feeding device applied to forced internal-external transfer type composite spinning, and belongs to the technical field of textile processing. The eccentric-braking filament feeding device comprises godet wheels symmetrically arranged on wing plates of a U-shaped fixing frame, wherein the godet wheels are eccentric wheels, openings of adjustable fixed through slots and a U-shaped opening of the U-shaped fixing frame are in the same direction, and the godet wheels are arranged in the adjustable fixed through slots of the wing plates through godet wheel shafts, so that a situation that filaments guided and output from the godet wheels are fed into a clamping opening of a front roller only in a position fixing manner is changed, and the forced internal-external transfer type composite spinning on the filaments and staples are realized. According to the eccentric-braking filament feeding device applied to the forced internal-external transfer type composite spinning, which is disclosed by the invention, the filaments drive the godet wheels to carry out passive eccentric rotation, so that no externally additional power is involved in practical production, the cost is low, the use is safe; meanwhile, the change to devices is simple, the individuation regulation and control, and maintenance of a single spindle can be realized, and the operation and the maintenance are convenient.

Description

technical field [0001] The invention relates to a filament feeding device which adopts eccentric braking to realize periodic reciprocating feeding of filaments into a ring spinning area in the process of forced internal and external transfer composite spinning, and belongs to the technical field of textile processing. technical background [0002] With the technological progress of textile materials and people's higher and higher demand for clothing fabric styles, the requirements for spinning technology are also getting higher and higher, and various spinning methods emerge in endlessly, such as sirofil spinning, siro spinning , compact spinning, cable spinning, core spinning, embedded spinning, etc. These new spinning methods have greatly enriched the spinning processing methods and significantly improved the quality of the finished thread. Among them, the spinning methods such as sirofill spinning, insert spinning and core spinning involve short fibers and filaments, whic...

Problems solved by technology

However, the above-mentioned composite spinning method requires that the position of the filament and the short fiber must be relatively fixed. In the obtained composite yarn structure, the position of the filament relative to the short fiber is relatively fixed, and the filament fails to maximize the composite yarn. Internal and external transfer in the yarn body, filaments and fibers cannot be naturally and evenly mixed and entangled in the yarn body

Therefore, the composite yarn produced by the above-mentioned composite spinning method has insufficient cohesion between the filament and the short fiber, and relative sliding between the long filament and the short fiber is easy to occur in the subsequent processing, not only the weaving efficiency is low, but also Poor surface quality and fabric abrasion resistance

[0003] In order to solve the problem of poor cohesion between filaments and short fibers in composite spinning, Chinese patent publication No. CN102677248A, published on September 19, 2012, is an invention titled "a forced internal and external transfer type filament composite Ring Spinning Method", the application discloses a forced internal and external transfer method that achieves full internal and external transfer of filaments and short fibers in the composite spinning process on a ring spinning frame and strengthens the cohesion between filaments and short fibers. The filament composite ring spinning method realizes the full internal and external transfer of the filament in the final composite yarn, and the filament and fiber in the composite yarn body are naturally and evenly mixed and tightly entangled, which solves the problem of the filament composite yarn in the subsequent Relative sliding between filaments and short fibers is easy to occur during processing, low weaving efficiency, poor cloth surface quality and fabric wear resistance; however, in the process of forced internal and external transfer filament composite ring spinning, by setting The third worm and gear transmission device of the headstock of the ring spinning machine drives the forced yarn guide device to perform integral reciprocating motion, and realizes the periodic reciprocating motion of the filament feeding into the spinning area. Therefore, this feeding method of the filament not only increases additional Energy consumption, and cannot meet the requirements of individual regulation and maintenance of a single spindle

The existing ring spinning core spinning filament feeding device is mainly composed of a fixed frame, a wing plate, and a guide wheel. The guide wheel is fixedly connected to the fixed rod through the wire wheel shaft. The plate and the fixed frame are perpendicular to each other, the godet wheel and the fixed frame are parallel to each other, and the ring spinning core spinning filament feeding device is fixed and installed on the cradle of the spinning frame through the fixed frame; although the device is simple in structure and easy to operate, it is Widely used, but because the guide wheel is a concentric wheel, the guide wheel and the fixed frame are parallel to each other, so that the guide wheel is perpendicular to the jaw line of the front roller, so the device realizes that the filament guided and output from the guide wheel is only fixed in position Feed to the nip of the front roller, only for positioning spinning
