Description

A kind of two-for-one twister overfeeding roller transmission mechanism
Technical field
The utility model belongs to field of textile machinery, more particularly, relates to a kind of two-for-one twister overfeeding roller transmission mechanism.
Background technology
Two-for-one twister is a kind of twisting equipment, and can realize one turn of two sth. made by twisting, twisting efficiency significantly improves than traditional twisting apparatus, and package capacity increases, myriametre non junction, and twisting quality significantly improves.Two-for-one twister comprises multiple two-for-one twisting spindle position, each two-for-one twisting spindle position mainly comprises spindle unit, overfeeding unit, winder unit and power unit, in the prior art, the driving mechanism of winder unit drives wireline reel drive to drive wireline reel to rotate, yarn is after spindle twisting, advance to overfeeding unit, advance to winder unit afterwards, complete twisting to produce, in the process, overfeeding unit is all be linked together with winder unit, driven by a driving mechanism, roller over feed rate(OFR) also only has two or three kind can select, cannot change again in working after roller over feed rate(OFR) setting simultaneously.In addition, traditional two-for-one twister overfeeding unit generally only has an overfeeding roller, to twisting silk thread play simultaneously dead twist and overfeeding two act on greatly.
As China Patent Publication No.: CN203754896U, publication date: on August 6th, 2014, disclosed a kind of two-for-one twister overfeeding roller device, it comprises at least two rollers, all rollers each freedom roller shaft supports to be installed, each roller shaft described is arranged in parallel, and on every root roller shaft, fixed cover is equipped with roller shaft drive, and the wireline reel drive in each described roller shaft drive and winder unit is in transmission connection by driving element.To be in transmission connection two or more rollers by transmission mechanism, carry out the structure that alternative existing two-for-one twister is only provided with an overfeeding roller, make yarn through repeatedly overfeeding process, strengthen the dead twist effect of roller, the winding tension of output is made to reduce to reach below 4CN, be applicable to short fiber and chemical-fibres filaments, be convenient to the sizing in rear road and directly process dye bobbin.But the wireline reel drive in this application case roller shaft drive and winder unit is in transmission connection by same driving element, namely cannot changes again after the setting of roller over feed rate(OFR), can not user demand be met; In addition, in the scheme of two rollers, first roller through-drive wheel and the second roller shaft drive by Timing Belt connection for transmission, and only carry out tensioning by a regulating wheel, synchronized movement weak effect between first roller through-drive wheel and the second roller shaft drive, has skidding.
And for example China Patent Publication No.: CN202187106U, publication date: on April 11st, 2012, disclosed a kind of Single-Stage Double-Twisting Frame, it comprises frame, be arranged on the two-for-one twisting spindles of frame side, bottom roll, hot case, false twist spindle, overfeeding roller and coiler device, and be arranged on the variable speed electric motors, particularly of frame opposite side, gear-box, travelling gear, some sprocket wheels, driving belt, false twisting motor and double twisting motor; Described two-for-one twisting spindles is positioned at the bottom of frame, and it is connected with double twisting motor by a double twisting tengential belt; Described bottom roll is arranged on roller shaft; Described false twist spindle is connected with false twisting motor by arranging a false twisting tengential belt; Described overfeeding roller is arranged on an overfeeding roller shaft; Described coiler device comprises a wireline reel; Described gear-box one end connects variable speed electric motors, particularly, and the other end is provided with travelling gear; Described some sprocket wheels are immobilizated in one end of wireline reel, overfeeding roller shaft and bottom roll axle respectively; Described driving belt is set in drive sprocket on sprocket wheel and rotates; The second gear be meshed with travelling gear is provided with in one end of described wireline reel.In this application case, be also be in transmission connection by a driving belt between overfeeding roller and coiler device, and adopt a variable speed electric motors, particularly driving to operate, equally also cannot change again after the setting of roller over feed rate(OFR); Meanwhile, bottom roll, overfeeding roller and coiler device adopt same motor to drive, and cause power of motor to select greatly, may occur skidding during driving belt transmission, and plant running vibrations are comparatively large, fluctuation of service, and impact is produced; In addition, this two-for-one twister only has an overfeeding roller, and the dead twist effect of roller is poor.
