Coil driving device for anti-pilling napped stovepipe covered yarn in covering machine

Abstract

The invention provides a spool drive unit for anti-pilling napped leg-slimming covered yarns in covering machines, belongs to the technical field of textiles and solves the technical problems such that since each spool needs a corresponding driver when the spools of the prior covering machine rotate, the rotation effect is poor; since the spools are provided with no positioning mechanism, the spools easily drop from the positioning rods and operation stability is poor. The spool drive unit disposed on a frame of the covering machine comprises a connecting plate which is elongated and which is fixedly connected to the frame; the connecting plate is horizontally disposed; a plurality of positioning rods are fixedly connected to the connecting plate in its length direction; the positioning rods are used for being sleeved with the spools and allow the spools to be axially fixed to the positioning rods; two ends of the connecting plate are provided with a driving wheel and a driven wheel connected to the frame, respectively; the driving wheel and the driven wheel are sleeved with a transmission belt; a compression structure is provided between every two adjacent positioning rods. The spool drive unit has the advantages of rotational reliability and good operational stability.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a coil driving device, in particular to a coil driving device for anti-pilling napped stovepipe coated yarn in a coating machine. Background technique [0002] The elastic yarn with spandex covered yarn as the main product has a wider and wider range of applications, and the demand for the product is increasing. Covered yarn, also known as wrapping yarn, is a new type of yarn structure. It uses filament or short fiber as the yarn core, and another filament or short fiber yarn is outsourced. The outsourcing yarn aligns the core in a spiral manner. Covering the yarn has the advantages of uniformity, bulkiness, smooth yarn with less hairiness, high strength and less broken ends. Covering yarn requires a large number of bobbins to be wound during the covering winding process. [0003] After searching, for example, Chinese patent literature discloses a disposable double-coated coated...

Problems solved by technology

[0004] Although the covering wire machine disclosed in this patent does not need to repeat the covering operation, it saves a lot of manpower and cost, and greatly improves the production efficiency. The driving device has poor rotation effect; and the wire coil has no reliable positioning mechanism, the wire coil is easy to fall from the positioning rod, and the working stability is poor. Coil drives are necessary
