Abstract
The invention relates to a mechanical lever compact spinning device which comprises a traversing tighter, a tighter post indication slot, a glue roller pressurizing bracket, a twist deterrent glue roller, etc. The twist deterrent glue roller is additionally arranged in front of a front glue roller on the front roller surface of a spinning machine; a traversing tighter is arranged between the front glue roller and the twist deterrent glue roller; the side of the tighter near the front roller is provided with a permanent magnet to lead the tighter to be closely stuck on the surface of the frontroller; a smooth fiber channel along the moving direction of a traction fiber strand is arranged on the contact surface of the tighter and the front roller; the fiber channel is in a 'V' shape with alarge inlet and a small outlet; lever pressure transferred by a glue roller pressurizing bracket leads the twist deterrent glue roller to be closely stuck on the surface of the front roller, so as tolead the fiber strand to become tight after passing through the fiber channel of the tighter; after the fiber strand is twisted into a yarn, the filoplume for spinning is remarkably reduced and the mightiness is remarkably improved. The invention relates to a compact spinning device with the advantages of stable pressurizing, low investment, low spinning cost and good consistency in the spinning quality between ingots.
Description
Technical field
The present invention relates to cotton, wool spinning and weaving machinery parts, is a kind of mechanical type lever compact spinning apparatus.
Background technology
At present, the district of swimming of spinning machine (both pair cushion rubber jaws were to front roller nip) distance is oversize, swims and distinguishes the curling retraction of friction generation that interior edge fiber loses tractive force and faces faster fibres mutually, makes the wideer of drawing-off yarn change, the yarn that broadens filoplume behind the twisting resultant yarn is too many, powerful on the low side.Existing various tight textile product complex structures, spinning cost height, closely textile product costs an arm and a leg, the phenomenon that make cotton mill occur cannot afford, difficultly safeguard, spinning quality ingot difference is big.Shortcoming as the tight textile product of prior art-magnet-type: 1) use unique leaf spring to give resistance twist rubber roll moulding pressure deficiency, with the passing of time the tired elastic force of leaf spring alleviates, and resistance twist rubber roll insufficient pressure descends spinning quality; 2) along with the prolongation resistance twist top roller diameter of service time is levigate gradually, the leaf spring pressurization can't be adjusted and replenish the pressure that gradually carefully reduces because of top roller diameter; 3) have only middle a bit being supported in the medial launder of tightening device on the locating support, the crooked phenomenon of tightening device that the uncontrollable fiber channel that is provided with because of multiple-grooved off-centre causes, crooked phenomenon has a strong impact on spinning quality; 4) fiber channel is only arranged, can not spin the higher Siro-spun yarn of quality; 5) traverse because of having only a fiber channel not have again, preceding rubber roll is short service life, increases cotton mill mill rubber roll recruitment cost and quality fluctuation; 6) the rubber roll support grip special configuration preceding rubber roller open retaining diameter of phi 9.5, the preceding rubber roll cost that must make shaft diameter specially and be Φ 9.5 is too high, original preceding rubber roller diameter of phi 11.5 positions of fine spining machine can't snap in use; 7) former rubber roll support is too soft, influences the precision of working in coordination after each parts is assembled, and produces the ingot differences of spinning quality; 8) fiber channel of drawing-off yarn and tightening device is difficult to accurately aim at, and lacks direct visualize setting, 9) only depend on unique magnet suction not guarantee precise and stable parallel of tightening device and front roller, the fiber channel of maintenance stabilized seal is a key of having spun yarn; 10) the spun yarn joint can only adopt to mention behind the yarn around clamp-oning fiber channel to resistance twist rubber roll and tightening device back and twist with the fingers disconnected method, the solderless wrapped connection head can't enter the inside fiber channel through the outside fiber channel when adopting the multi-fibre passage, existing product can only be established a fiber channel, a solderless wrapped connection speed is slow, and the spinner is uncomfortable.This jointing method is to spin the reason that the match network closely spins, and more can not realize a plurality of fiber channel spinning.
