Promising effect solves problems of the prior art, many significant explorations have been done in the industry, a kind of warp-feeding mechanism and Rapier looms of loom are disclosed as had patent CN201020222734.1 now, it has adopted two cover warp-feeding mechanisms, wherein a set of warp-feeding mechanism is provided with warp let-off tenslator, can knit the fabric of two kinds of different warp thread raw materials of system, but the complex structure of this tenslator, and the briquetting on depression bar is often because vibration equipment falls, thereby the tension force that affects equipment is controlled.

Therefore be necessary existing Rapier looms warp let-off structure is carried out to technological innovation further.

[utility model content]

The purpose of this utility model is for the defect of prior art and deficiency, and Rapier looms warp-feeding mechanism a kind of simple in structure, reasonable in design, easy to use is provided.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of Rapier looms warp-feeding mechanism described in the utility model, comprise the first warp beam, first back rest, the second warp beam and second back rest, described the first warp beam and the second warp beam are fixedly installed on respectively on support, described the second warp beam two ends are respectively arranged with friction pulley, described the first warp beam two ends are respectively arranged with friction pulley, it also comprises first dead turn and second dead turn, and described second dead turn is fixedly installed on support; First dead turn one end and second dead turn one end are hinged, and first dead turn other end is threaded by the butterfly screw mutually with second dead turn other end, and described friction pulley is nested in the inner ring that first dead turn and second dead turn surround.

Further, the inner ring that described first dead turn and second dead turn surround also is nested with rubber ring.

Further, between described first dead turn other end and second dead turn other end, also be provided with spring, described spring is nested in the screw mandrel of butterfly screw.

After adopting said structure, the utility model beneficial effect is: a kind of Rapier looms warp-feeding mechanism described in the utility model, comprise the first warp beam, first back rest, the second warp beam and second back rest, described the first warp beam and the second warp beam are fixedly installed on respectively on support, described the second warp beam two ends are respectively arranged with friction pulley, described the first warp beam two ends are respectively arranged with friction pulley, and it also comprises first dead turn and second dead turn, and described second dead turn is fixedly installed on support; First dead turn one end and second dead turn one end are hinged, and first dead turn other end is threaded by the butterfly screw mutually with second dead turn other end, and described friction pulley is nested in the inner ring that first dead turn and second dead turn surround.While using the utility model, control the frictional force between friction pulley and first dead turn and second dead turn by the butterfly screw, greatly improved the convenience that warp let-off tension force is controlled, reduced labour intensity, also avoided affecting because of vibration equipment the phenomenon that warp let-off tension force is controlled; By in the first warp beam, adding tenslator, greatly improved the scope of application of equipment, also avoided damaging because of single tenslator the normal production that affects two kinds of different warp thread raw material fabrics.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
