Description

Two-component core wire coating machine

technical field

The design of the utility model relates to a hollow spindle covering machine, which is suitable for the covering process of the core yarn composed of two different yarns, that is, the double-component core yarn.

Background technique

The hollow spindle covering machine uses the high-speed rotating spindle to drive the yarn on the bobbin to unwind, and in the process, the covering yarn is wrapped on the core wire passing through the hollow spindle rod. It is especially suitable for covering various filament yarns. , can produce evenly covered and compact core-spun yarn. This kind of equipment is currently widely used in the production of various core yarns. The existing hollow spindle wrapping machine is only suitable for single core filament wrapping, not suitable for bicomponent core filament wrapping composed of two different tensile properties yarns, for example, one elastic filament and one non-elastic filament Yarns consist of bicomponent core filament wrapping. With the increasing demand for specialty corespun yarns with different functions, such as wire or other specialty fiber core-spun elastic yarns, the processing of these elastic corespun yarns requires bicomponent core yarn coating. The non-elastic yarn in the bicomponent core yarn can improve the weaving performance of the core-spun yarn, and the non-elastic core yarn can be dissolved or broken during subsequent processing, so that the core-spun yarn can recover its elasticity. These special structure core-spun yarns cannot be manufactured with existing hollow spindle covering machines.

Contents of the invention

The design purpose of the utility model is to transform the existing hollow spindle covering machine, so that it can be applied to the double-component core filament covering composed of two different yarns.

The utility model consists of a frame and a transmission mechanism, a winding bobbin frame and a winding roller, an upper roller type overfeeder for the spindle and a lower tooth type overfeeder for the spindle, a guide nozzle and a spindle upper and lower guides, a hollow spindle and a dragon. It is composed of belt, non-elastic core wire axial retraction cylinder holder and elastic wire radial retraction cylinder holder. The utility model adopts a motor to drive the dragon belt, the hollow spindle is driven by the dragon belt, and the upper and lower overfeeders of the spindle are driven by the transmission mechanism, as well as two core wire conveying devices and a coiling mechanism. The axially decomposed non-elastic core wire is fed into the hollow spindle rod through the under-spindle wire guide, and the radially decomposed elastic core wire is fed into the hollow spindle rod through the toothed overfeeder. At the same time, the two core wires passing through the hollow spindle are The covered yarn package is unwrapped on the package, and then it is wound onto the core yarn package through the yarn guide on the spindle and the pressure roller overfeeder. The draft of the non-elastic core yarn is controlled by the overfeeder on the spindle and the yarn guide under the spindle, while the draft of the elastic core yarn is controlled by the upper and lower overfeeders, so that the two core yarns pass through the hollow with different draft ratios. Spindle and covered with flour. The covered yarn package should be balanced and corrected before winding. The overfeeder on the spindle adopts a pressure roller type overfeeder, and the overfeeder under the spindle adopts a toothed overfeeder, and is located beside the radial unwinding barrel frame. The design of the utility model is suitable for the coating of the double-component core yarn composed of yarns with different tensile properties, and can be drafted separately according to the different drafting requirements of the two core yarns, so as to make a uniform and tight coating. core yarn. It is especially suitable for special thread coverings, such as metal wire coverings, or covering of other fiber threads that are easily broken when subjected to impact. The core-spun yarn manufactured by the device of the utility model has a stable structure and good weaving performance, and can meet the requirements for warp and weft yarns of general shuttleless or shuttle weaving.

Description of drawings

The accompanying drawing of the description is a sectional view of the design of the utility model. In the figure, 1 is a coiling creel, 2 is a coiling roller, 3 is a guide nozzle, 4 is a pressure roller type overfeeder, 5 is an upper yarn guide, and 6 is a Hollow spindle, 7 is the dragon belt, 8 is the lower wire guide, 9 is the axial unwinding bobbin frame, 10 is the tooth form overfeeder, 11 is the radial unwinding bobbin frame, and 12 is the frame.

Detailed ways

In the design of the utility model, the yarn trending path is as follows (referring to the accompanying drawings in the description):

The core yarn (1) non-elastic yarn is unwound by the upper bobbin on the bobbin holder 9 axially, and then fed into the hollow spindle 6 through the lower yarn guide 8, and the core yarn (2) elastic yarn is unwound on the bobbin holder 11 by the radial direction. After the bobbin is deflated, it is fed into the hollow spindle 6 through the tooth form overfeeder 10. After the two core filaments are coated with the desolvated yarn on the coated surface yarn bobbin, they pass through the upper yarn guide 5 and are overfed by a pressure roller. The device 4 is wound onto the core-spun yarn bobbin by the take-up roller 2 via the guide nozzle 3.

The design of the utility model is suitable for the transformation of the existing hollow spindle coating machine.
