Abstract
The invention provides a suction type spinning fiber converging method. An airflow guide device is arranged on an output side of a front roller jaw of each spindle position and is combined with a fiber converging channel to form control on fiber strands and discrete fiber converging; the fiber converging channel generates airflow from outside to inside due to negative pressure; the airflow sucks the fiber strands to enter an inner cavity of the fiber converging channel; the airflow guide device is used for controlling the front roller jaw and an exposed region of a surface, so that the fiber strands, and free single fibers and ultra-short single fibers which appear along with the fiber strands are controlled to enter a direction and a path of a suction hole of the fiber converging channel under the action of the airflow, and the two groups of fiber strands output by a front roller are controlled to be converged at intervals on the left and right sides of the suction hole of the fiber converging channel along with the airflow; the fiber strands are converged into bundles at the edge of the suction hole of the fiber converging channel and enter in sequence; and under the action of a twisting mechanism, the two groups of bundled fiber strands are twisted in a doubled yarn shape, and the length of the part, which is exposed out of a yarn body, of a single fiber is inhibited, and the generation of long down is reduced.
Description
Technical field
The invention belongs to ring spindle yarn technical field, relate to aggregation method and the suction-type spinning repiece method and apparatus of the fiber of a kind of suction-type spinning.
Background technology
nullRing spindle yarn suction-type Yarn spinning method is in patent 201310403847.X，Propose the Yarn spinning method of a kind of new ideas，On the front roller outlet side yarn road of ring throstle，It is provided with negative-pressure air-flow suction-type delivery device，Fiber strip from front roller output，Export once front roller nip，I.e. it is introduced into yarn hole gathers bunchy by the air-flow produced in yarn hole that enters on negative pressure collecting gas storehouse、It is twisted into，Spinning uses negative-pressure air-flow，Instant attraction、Gather the fiber strip of front roller output，By adjusting、Change the relative position into yarn hole with fiber strip、Change the shape into yarn aperture、Change the shape into Sha Kongsha road inner chamber，Stop and be positioned at the ultimate fibre in yarn limit and flying away of fiber head end，The twisted effect of fiber in control fibre bundle，Reduce the generation of long filoplume，Use 201310403847.X patented technology，Single fiber-bundles sucks，Because the transmission of the twist is faster than the boundling of fiber，Control to filoplume produces little effect，Two groups of fibers are from the parallel output of front roller nip，Enter in the poly-fine access opening of front roller nip outlet side，Edge boundling in poly-fine passage aperture，In poly-fine access opening，Two groups of fibre bundles converge，Under the effect of twisting and winding mechanism，And close twisting resultant yarn，This filoplume to reducing more than 3mm，There is well effect，But，Often due to there is many ultimate fibre filoplumes in the surface of rove，Rove bar there is also many ultrashort fibers，After the output of these ultimate fibres premenstrual roller draft，There will be and be free in situation outside fiber strip，By 201310403847.X patented technology，These free ultimate fibres can not synchronize boundling with fiber strip，But these free ultimate fibres can be by airstream suction，Enter into yarn hole with air-flow disorderly，Form long filoplume，Yarn filoplume index is caused to deteriorate，The joint of 201310403847.X patented technology draws repiece and the bond process of yarn simultaneously，It is to complete inside the negative air compression cabin closed，Its mechanism is complicated，Controllability and effectiveness are poor，It is unfavorable for the application of reality，These are all the key technical problems that suction-type spinning technique needs to solve.
Summary of the invention
It is an object of the present invention to provide the fiber aggregate method of a kind of suction-type spinning, poly-fine passage is used to combine with air flow guiding device, control two groups of chopped fiber yarns and free ultimate fibre and superbhort fiber, controlled, in an orderly manner boundling enter poly-fine passage, doubling twisting in poly-fine passage.
A kind of suction-type spinning repiece method of offer is provided, can facilitate, more effectively draw for joint repiece and the joining operations of yarn.
