Description

Weft yarn cutting means

Technical field

The utility model relates to cutting means, especially, it relates to a kind of weft yarn cutting means for air-jet loom.

Background technology

Glass fibre plain weave grid cloth generally uses air-jet loom to weave, the structure of glass fibre plain weave grid cloth is very unstable, selvedge needs to use POLYESTER YARNS to lockstitch a border, weft yarn beyond the lock seaming yarn of cloth cover side is that the electronic scissors carried by air-jet loom is sheared, but the impact due to the clamping of electronic scissors, main jet air-flow and warp tension difference, cause cloth cover side weft yarn to be cut out and cut bending, and the quality problems on limit bad, rotten of lockstitching a border often occur, seriously have impact on the quality of production of product.

Practical novel content

The utility model object is to provide a kind of weft yarn cutting means, and to solve in prior art, weft yarn is cut out and cut bending, the problem that the quality problems on limit bad, rotten of lockstitching a border often occur.

For achieving the above object, the utility model provides a kind of weft yarn cutting means, comprising: mounting plate, and the side of described mounting plate is provided with motor, and the rotating shaft of described motor is provided with cam; Another side of described mounting plate is provided with bolt, and described bolt is equipped with reset components and knife bar; One end of described reset components and the screw cap end of described bolt are fixed, and the other end and described knife bar are fixed; The end of described knife bar is provided with blade, is provided with backing plate below described blade, and described backing plate is fixed by pad rack and described mounting plate; Having offered U-type groove on described knife bar, the described cam on described motor shaft is positioned at described U-type groove, is fixed with block and described cam engagement above described cam on described knife bar.

Further, described reset components is torsion spring.

Further, described backing plate is rubber bearing.

The utility model has following useful effect:

After installing this weft yarn cutting means additional between the original electronic scissors of air-jet loom and lock seaming yarn, weft yarn can be carried out sanction and cut by this weft yarn cutting means automatically, completely solving weft yarn sanction and cut bending, the quality problems on limit bad, rotten of lockstitching a border, substantially increase quality product; And, this cutting means structure is simple, and reliability height, the improvement cost for original equipment is low.

Accompanying drawing explanation

Below with reference to figure, the utility model is described in further detail. The accompanying drawing of a part forming the application is used to provide of the present utility model it is further understood that schematic description and description of the present utility model is for explaining the utility model, does not form improper restriction of the present utility model. In the accompanying drawings:

Fig. 1 is the structural representation of the utility model weft yarn cutting means preferred embodiment; And

Fig. 2 is the side-view of the utility model weft yarn cutting means preferred embodiment.

Description of reference numerals:

1, reset components; 2, bolt; 3, motor; 4, pad rack; 5, knife bar; 6, cam; 7, block; 8, backing plate; 9, blade; 10, mounting plate.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.

Referring to Fig. 1 and Fig. 2, preferred embodiment of the present utility model provides a kind of weft yarn cutting means, comprising: mounting plate 10, and the side of described mounting plate 10 is provided with motor 3, and the rotating shaft of described motor 3 is provided with cam 6; Another side of described mounting plate 10 is provided with bolt 2, and described bolt 2 is equipped with reset components 1 and knife bar 5; One end of described reset components 1 and the screw cap end of described bolt 2 are fixed, and the other end and described knife bar 5 are fixed; The end of described knife bar 5 is provided with blade 9, is provided with backing plate 8 below described blade 9, and described backing plate 8 is fixed by pad rack 4 and described mounting plate 10; Having offered U-type groove on described knife bar 5, the described cam 6 in the rotating shaft of described motor 3 is positioned at described U-type groove, is fixed with block 7 and coordinates with described cam 6 above described cam 6 on described knife bar 5.

During use, this weft yarn cutting means is arranged between the lock seaming yarn of the original electronic scissors of air-jet loom and glass fiber plain weave grid cloth. During work, motor 3 band moving cam 6 rotates, and cam 6 puts vertex by block 7 knife bar 5 top, and now knife bar 5 and blade 9 lift, and reset components 1 produces deformation; When cam 6 continues to rotate, arriving the support that the knife bar 5 after vertex loses suddenly cam 6, now knife bar 5 falls under the effect of reset components 1 with deadweight fast with blade 9, disconnected for the weft yarn hand hay cutter of glass fiber plain weave grid cloth on backing plate 8. After fell walked out by weft yarn, by this weft yarn cutting means severing, waste selvage yarn is drawn by the slitter edge creel of loom side, by the snail wire on the loom back rest, waste selvage yarn is directed to the left side of loom, then realizing the strand limit to weft yarn by heald frame and reed to lock, the weft yarn of severing is discharged outside loom together with waste selvage yarn. Weft yarn can be carried out sanction and cut by this weft yarn cutting means automatically, completely solves weft yarn sanction and cuts bending, and the quality problems on limit bad, rotten of lockstitching a border, substantially increase quality product; And, this cutting means structure is simple, and reliability height, the improvement cost for original equipment is low.

Preferably, described reset components 1 is torsion spring. One end of torsion spring and the screw cap end of bolt 2 are fixed, and the other end and knife bar 5 are fixed, and when knife bar 5 lifts, torsion spring produces deformation, and lose the support of cam 6 at knife bar 5 after, torsion spring replys deformation, and knife bar 5 is fallen fast. Torsion spring structure is simple, reliable, and long service life.

Preferably, described backing plate 8 is rubber bearing. Rubber bearing quality is soft, it is possible to greatly extend the work-ing life of blade 9.

The foregoing is only preferred embodiment of the present utility model, it is not limited to the utility model; For a person skilled in the art, the utility model can have various modifications and variations. All within spirit of the present utility model and principle, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
