Improved yarn coating machine and operation method thereof

Abstract

The invention provides an improved yarn coating machine and an operation method thereof. The improved yarn coating machine comprises a spandex roller, wherein the spandex roller is sleeved with a plurality of spandex rolls; a plurality of yarn coating mechanisms are arranged above the spandex roller, and comprise bobbins and yarn coating spindles for driving the bobbins to rotate; a transmission mechanism is connected below the yarn coating spindles; tensioning assemblies are arranged between the yarn coating spindles and the spandex rolls; a coiling roller is arranged above the yarn coating mechanisms and is sleeved with a coiling wheel; the coiling wheel is divided into N+1 coiling unit sections through N separation rings; positioning reeds are arranged at the side edges of the coiling unit sections; a position adjusting mechanism is arranged between the bobbins and the coiling wheel, and comprises a left balance tensioner and a right balance tensioner; a plurality of tension rods are connected between the left balance tensioner and the right balance tensioner; each tension rod is provided with a position adjusting reed; connected clamping blocks are arranged at the left side of the adjusting reeds, and connected clamping grooves are formed in the right side of the adjusting reeds; and the connected clamping blocks and the connected clamping grooves are connected in an embedding manner.

Description

Technical field [0001] The invention belongs to the technical field of textile machinery, and relates to a covering machine, in particular an improved yarn covering machine and an operation method thereof. Background technique [0002] At present, domestic spandex core-spun silk (silk) fabrics have been very popular. The main types are spandex filament and staple fiber core-spun yarn and filament covered yarn. In product development, it is mainly based on the selection of outer yarn with different fiber materials. Its core filaments are mainly continuous spandex filaments, and the outer short fibers include cotton, polyester cotton, acrylic and wool fibers, and the outer chemical fiber filaments include polyester filaments and nylon filaments. Ordinary spandex covered yarn is centered on spandex, wrapped with polyester, nylon, etc. to form elastic yarns. Generally covered yarns are divided into single covered yarns and double covered yarns. Single covering yarn machine can only...

Problems solved by technology

The covered wire machine can realize the double covering of the yarn. When covering the yarn, the yarn passes through the upper and lower covering mechanisms at the same time. However, the existing covering machine is switching between single covering and double covering, or different yarns When replacing the combination, the operation is cumbersome, and it is necessary to re-wire, re-spin the machine, re-match, etc., which reduces the work efficiency and increases the work cumbersome amount.
