Service life.Meanwhile scissors group causes in use there is also the movement due to cutting blade plus pressurization locking nut pine
Dynamic phenomenon.
Summary of the invention
The purpose of the present invention is in view of the deficiency of the prior art, provide a kind of used in jet loom weft yarn invagination scissors
Group.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of used in jet loom weft yarn invagination scissors group, including fixed blade piece, shears blade, scissors group installation axle, pressurization
Spring leaf, pressurization locking nut and fastening screw, the fixed blade piece, shears blade and pressing spring on piece are respectively equipped with
Mounting hole, the scissors group installation axle bottom are equipped with scissors group fixing seat, and scissors group installation axle top outer is equipped with to be added with described
The compatible external screw thread of locking nut is pressed, scissors group installation axle top is equipped with internal thread hole along central axis direction, internal thread hole
Top is internal taper face, and the symmetrical expansion slot along central axis direction, the movable scissors are additionally provided at the top of scissors group installation axle
Piece, fixed blade piece pressing spring piece pass sequentially through mounting hole from bottom to top and are sheathed in the scissors group installation axle, pass through institute
It states pressurization locking nut the shears blade, fixed blade piece, pressing spring piece are fixed in the scissors group installation axle,
The fastening screw screws in the internal thread hole at the top of the scissors group installation axle, and the pressurization locking nut is fixed and prevented
Only pressurization locking nut loosens.
In the further design scheme of the present invention, it further includes axle sleeve that used in jet loom weft yarn, which folds into scissors group, the axle sleeve
It is sleeved in the scissors group installation axle and pads the bottom surface for being set to the shears blade.
In the further design scheme of the present invention, above-mentioned fixed blade piece and shears blade are whole hard alloy knife
Piece, the axle sleeve are hard alloy axle sleeve.
The present invention have it is following prominent the utility model has the advantages that
1, the present invention substitutes the welded type blade of old model using whole hard alloy blade；And hard alloy axle sleeve is increased,
So that the rotation pair of friction components of steel to steel in old model is become the friction of hard alloy and hard alloy, is cut to be greatly improved
The service life and shear effect of knife group.
2, the present invention is installed scissors group pressing spring piece in old model by shears blade side, is designed to be cut by fixation
The installation of blade side.So that pressing spring piece is become retaining element from movement friction part, prevents pressing spring
The abrasion of piece extends the service life of scissors group, improves scissors so that the shear pressure of scissors group be made to become more stable
The shear effect of group.
3, the present invention devises completely new scissors spring leaf pressurization locking mechanism, is designed using internal taper face tight with scissors group
Gu the external taper face of screw cooperates, make to expand outside the outer radial of scissors group installation axle, to make spring leaf pressurization nut and scissors
The relative position of group installation axle is kept fixed.Scissors group is completely avoided to cause due to the movement of cutting blade in use
The phenomenon that locking nut that pressurizes loosens.The operation that this new design makes used in jet loom weft yarn fold into scissors group more may be used
It leans on.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Referring to Fig. 1-4, one of present invention used in jet loom weft yarn folds into scissors group, including fixed blade piece 1, activity
Shear blade 2, scissors group installation axle 3, pressing spring piece 4, pressurization locking nut 5, fastening screw 6 and axle sleeve, 1 He of fixed blade piece
Shears blade 2 is whole hard alloy blade, and axle sleeve 11 is hard alloy axle sleeve.Fixed blade piece 1,2 and of shears blade
Mounting hole is respectively equipped on pressing spring piece 4,3 bottom of scissors group installation axle is equipped with scissors group fixing seat 7, scissors group fixing seat 7
It is mounted on the scissors knife rest of air-jet loom.3 top outer of scissors group installation axle is equipped with compatible with pressurization locking nut 5 outer
Screw thread, 3 top of scissors group installation axle are equipped with internal thread hole 8 along central axis direction, and the top of internal thread hole 8 is internal taper face 9, is cut
The symmetrical expansion slot 10 along central axis direction, axle sleeve 11, shears blade 2, fixed blade are additionally provided at the top of knife group installation axle 3
Piece 1, pressing spring piece 4 pass sequentially through mounting hole from bottom to top and are sheathed in scissors group installation axle 3, pass through the locking nut 5 that pressurizes
Shears blade 2,1 pressing spring piece 4 of fixed blade piece are fixed in scissors group installation axle 3, by pressurizeing, locking nut exists
The variation of axial position is to be adjusted the shear pressure between fixed blade piece 1 and shears blade 2；Fastening screw 6 is revolved
It twists in the internal thread hole 8 at 3 top of scissors group installation axle, pressurization locking nut 5 is fixed and prevents pressurization locking nut 5 from occurring
It loosens.
The present invention substitutes the welded type blade of old model using whole hard alloy blade；And increase hard alloy axis
Set, makes the rotation pair of friction components of steel to steel in old model become the friction of hard alloy and hard alloy, to increase substantially
The service life and shear effect of scissors group.
The present invention is installed scissors group pressing spring piece 4 in old model by 2 side of shears blade, is designed to be cut by fixation
The installation of 1 side of blade.So that pressing spring piece 4 is become retaining element from movement friction part, prevents pressurization bullet
The abrasion of reed 4 extends the service life of scissors group, improves so that the shear pressure of scissors group be made to become more stable
The shear effect of scissors group.
The present invention devises completely new scissors spring leaf pressurization locking mechanism, is designed using internal taper face 9 tight with scissors group
Gu the external taper face of screw 6 cooperates, make to expand outside the outer radial of scissors group installation axle 3, to make spring leaf pressurization nut and cut
The relative position of knife group installation axle 3 is kept fixed.Completely avoid scissors group in use due to the movement of cutting blade and
The phenomenon that locking nut 5 that causes plus pressurize loosens.This new design makes used in jet loom weft yarn fold into the operation of scissors group more
Add reliable.
The above are preferred embodiments of the present invention, all any changes made according to the technical solution of the present invention, and generated function is made
When with range without departing from technical solution of the present invention, all belong to the scope of protection of the present invention.
