Abstract
The utility model relates to the field of the weaving of a computerized flat knitting machine, particularly relates to a yarn damping device, and aims to solve the problem that yarns are frequently slack in the weaving process of the computerized flat knitting machine in the prior art. The yarn damping device comprises a mandrel, a bobbin sleeving the mandrel and a yarn barrel sleeving the bobbin, and further comprises a bowl-like damping sleeve which sleeves the mandrel and is reversed above the yarn barrel, wherein a bottom hole used for enabling the mandrel to pass through is formed in the bottom of the damp sleeve, and a gap used for enabling yarns to pass through is formed between the bottom hole and the mandrel. The damping sleeve is arranged in the yarn damping device, certain damp is given for the yarn damping sleeve by depending on the weight of the damping sleeve when the yarns just get out the yarn barrel, so that the probability of loosing and knotting the output yarns can be maximally limited; furthermore, the yarns can keep certain tension but not influence the yarn feeding speed by the damp when the computerized flat knitting machine stops, so that the yarns have uniform tension, the phenomenon that the yarns are twisted and knotted or slide off due to the loosing can not be generated, and the normal operation of computerized flat knitting machine can be guaranteed.
Description
Technical field
The utility model relates to Computerized flat knitting machine braiding field, relates in particular to a kind of yarn damping unit.
Background technology
In Computerized flat knitting machine braiding process; yarn often can relax; and be difficult to again be stretched; can cause knotting to cause broken yarn or useless sheet; can be because gliding phenomenons such as producing yarn self winding, the overturning of line cylinder, particularly for the ELASTANE YARNS that is added with elastic class, problems has badly influenced finished product rate and braid efficiency; operating efficiency cannot be guaranteed, and has improved production cost.
Utility model content
The utility model provides a kind of yarn damping unit, is intended to solve in prior art in Computerized flat knitting machine braiding process the problem that yarn often can be lax.
In order to solve above technical problem, the utility model is achieved through the following technical solutions: a kind of yarn damping unit, comprise mandrel, be socketed in spool on mandrel, be socketed in the yarn bobbin on spool, also comprise the bowl-shape damping sleeve that is socketed on mandrel and tips upside down on yarn bobbin top, the bottom of described damping sleeve is provided with the bottom outlet for mandrel is passed, and leaves the gap that yarn is passed between described bottom outlet and mandrel.
Further, on described damping sleeve lateral wall, be also socketed with dismountable annulus; By installation and removal annulus, can change the pressure of damping sleeve to yarn bobbin, thereby change the tension force of yarn.
Further, described annulus is arranged on by screw thread on the lateral wall of damping sleeve; Be convenient to the dismounting of annulus.
Further, described annulus is arranged on by magnetic force on the lateral wall of damping sleeve; Be convenient to the dismounting of annulus.
Compared with prior art the utility model has the advantages that: in the utility model, be provided with damping sleeve, when the firm output cylinder of yarn, just relied on self gravitation to give certain damping by yarn damping sleeve, limited to greatest extent the possibility that LSOR knotting; But this damping makes yarn can keep some tension not affect in the time that straight-bar machines is shut down and send yarn speed, makes yarn have uniform tension force, no longer occurs because of Yarn relaxation tangled up and knotted or landing, guarantee machine is normally worked.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is for partly to cut open rear structural representation of the present utility model by damping sleeve;
Fig. 3 is the structural representation of damping sleeve in the utility model.
Detailed description of the invention
Consult Fig. 1, Fig. 2 and Fig. 3, a kind of yarn damping unit, comprise mandrel 2, be socketed in spool 3 on mandrel 2, be socketed in the yarn bobbin 4 on spool 3, also comprise the bowl-shape damping sleeve 5 that is socketed on mandrel 2 and tips upside down on yarn bobbin 4 tops, the bottom of described damping sleeve 5 is provided with the bottom outlet 51 for mandrel 2 is passed, between described bottom outlet 51 and mandrel 2, leave the gap that yarn 1 is passed, described damping sleeve 5 is pressed in by self gravitation the frictional force on yarn bobbin 4, mobile yarn 1 being produced and equals the required tension force of yarn 1; On described damping sleeve 5 lateral walls, be also socketed with dismountable annulus 6, described annulus 6 has different specifications, and annulus 6 quality of every kind of specification are all different, can on damping sleeve 5, add as required different annulus 6; Described annulus 6 is arranged on the lateral wall of damping sleeve 5 by screw thread, or described annulus 6 is magnet, and damping sleeve 5 is ironwork, and annulus 6 is arranged on the lateral wall of damping sleeve 5 by magnetic force.
When use, spool 3 is socketed on mandrel 2, yarn bobbin 4 is socketed on spool 3; Damping sleeve 5 is socketed on mandrel 2, and relies on gravity pressure on yarn bobbin 4, the tension force required according to yarn 1 adds corresponding annulus 6 on yarn bobbin 4, and yarn 1 is connected with outside with the gap of mandrel 2 junctions through damping sleeve 5.
In the utility model, be provided with damping sleeve, when the firm output cylinder of yarn, just relied on self gravitation to give certain damping by yarn damping sleeve, limited to greatest extent the possibility that LSOR knotting; But this damping makes yarn can keep some tension not affect in the time that straight-bar machines is shut down and send yarn speed, and because the gravity of damping sleeve is constant, yarn has uniform tension force, no longer occurs because of Yarn relaxation tangled up and knotted or landing, guarantee machine is normally worked; By adding annulus, can change the gross weight of damping sleeve, can the demand of yarn to differential tension.
The foregoing is only specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
