Description
Technical field
The utility model relates to a kind of loom weft insertion device, is a kind of cam weft insertion device of loom specifically.
Background technology
Cam weft insertion device controls the movement locus of sword belt sword head in loom 360 ° of motion processes by changing conjugate cam curve, thus completes weft transfer smoothly.Existingly wefting insertion conjugate cam is directly arranged on the horizontal main shaft of loom as the cam weft insertion device on SM93 machine, drive wefting insertion balance staff and wefting insertion tooth arm to make front-rear reciprocation movement and drive one group of right angle spiral bevel gear driver output axle, sword transmission wheel, sword belt, sword head again through output gear shaft again, its shortcoming is to regulate the position of wefting insertion traverse on wefting insertion balance staff, regulating part is heavy, wefting insertion balance staff and wefting insertion tooth arm make front-rear reciprocation movement in loom both sides, consequent inertia cannot be cancelled out each other, cause loom pitching, affect service life; And wefting insertion tooth arm neither be fixed with the output shaft of sword transmission wheel by Direct driver, driving member multimachine structure is complicated, reduces rigidity, consumes too much kinetic energy.
Summary of the invention
For the above-mentioned deficiency of prior art cam wefting insertion, the utility model provides a kind of drive disk assembly and simplifies, and operation vibration is little, is conducive to increasing the service life, and can take into account the cam weft insertion device of the loom of wefting insertion rigidity and power consumption.
The technical solution adopted in the utility model is: a kind of cam weft insertion device of loom, comprise loom frame, conjugation camshaft, wefting insertion balance staff, rotor, wefting insertion link rod, trough of belt wefting insertion tooth arm, tooth arm fulcrum, clamp, output gear shaft, sword transmission wheel, sword belt and sword head, described conjugation camshaft comprises conjugate cam group and rotating shaft, conjugate cam group is socketed on rotating shaft and is fixedly connected, and the direction of rotation of the conjugate cam group on rotating shaft is with loom bilateral symmetry, described wefting insertion balance staff comprises balance staff and upper, lower rotor part, balance staff is rotatably connected on loom frame, balance staff is provided with, two cam bits that lower rotor part takes turns cam set respectively together coordinate and do thereon in gapless rolling condition, one end of the non-rotating hinged place of balance staff and wefting insertion link rod is movably hinged, described tooth arm fulcrum is installed on loom frame, trough of belt wefting insertion tooth arm rotary sleeve is connected on tooth arm fulcrum, trough of belt wefting insertion tooth arm is provided with arc groove, the other end and the clamp of described wefting insertion link rod are movably hinged, it is along arc groove slidable adjustment clamped condition in arc groove that clamp is fixed by screws on wefting insertion tooth arm, described output gear shaft is connected on loom frame through bearing rotary, output gear shaft center of circle line and rotating shaft center of circle line parallel, the tooth mouth of trough of belt wefting insertion tooth arm drives the gear on engagement output gear shaft, output gear shaft has been fixedly connected sword transmission wheel, sword belt is around on sword transmission wheel, sword head is installed on sword belt head.
Further, described rotating shaft to be arranged on loom frame in front and back through bearing and to connect with loom main shaft synchronous rotary.
Again further, the center of circle of described arc groove and the axis of rotation decentraction of tooth arm fulcrum.
When loom works, loom main shaft synchronous rotary driven rotary axle rotates, rotating shaft drives two cam bits of taking turns cam set altogether to drive, lower rotor part gapless is rolled, by upper, lower rotor part drives wefting insertion swing arm on loom frame, rotarily drive hinged wefting insertion link rod thereon, clamp be fixedly clamped diverse location in deep-slotted chip breaker time, wefting insertion link rod connects clamp and drives trough of belt wefting insertion tooth arm to rotate around tooth arm fulcrum through arc groove, again through output gear shaft, sword transmission wheel drives sword belt to complete wefting insertion by sword head, wefting insertion link rod drives and the trough of belt wefting insertion tooth arm anglec of rotation limited by clamp realizes the adjustment of different wefting insertion traverse.
Adopt technique scheme, the utility model has the advantages that:
1, by wefting insertion conjugation camshaft center of circle line and the output shaft center of circle line parallel being fixed with sword transmission wheel, simplify transmission mechanism, make wefting insertion have the strongest rigidity, ensure that the moment of slow train handing-over and handing-over at a high speed switches and can not break sword head.
2, wefting insertion balance staff and wefting insertion tooth arm are symmetrical reverse motion in two lateral movements of loom, motional inertia kinetic energy of cancelling out each other when not needing any counterweight, reduce wefting insertion vibration, increase the service life, and are suitable for weaving machine high-speed running.
3, only clamp meets wefting insertion traverse adjustment at arc groove internal fixtion clamped position need be adjusted, on the handing-over of wefting insertion central authorities without impact, be more conducive to regulate traverse, for space four-bar linkage weft insertion device and screw rod weft insertion device, the rigidity for Looms high speed wefting insertion has suitable advantage with handing-over stability.
The utility model drives wefting insertion balance staff make the crankmotion of certain angle thus make the reciprocating rotary around tooth arm fulcrum through wefting insertion drive links trough of belt wefting insertion tooth arm through upper lower rotor part when doing 360 ° of rotations by conjugation camshaft, again through output gear through-drive sword transmission wheel so that drive reciprocating around the sword belt on sword transmission wheel, in loom bilateral symmetry, this weft insertion device is set, each self-driven sword head be fixed on sword belt, completes the handing-over wefting insertion process sending to connect to weft yarn one in loom central authorities.
