Description
Technical field
The invention belongs to field of textile equipment, relate to a kind of assembly of griffing of jacquard.
Background technology
Jacquard is a kind of textile tool.On jacquard, card is enclosed within cylindrical fireworks, and often knit a latitude and climb over one piece of card, cylindrical fireworks are once pressured to eedles.When on card during perforation, the head end of eedles puts in the eyelet of line version and cylindrical fireworks, the hook end of staight needle is still hung over and griffes.When griffing to rise, staight needle and then rises, and drives heald to promote, now penetrates the organizine of harness eye also along with lifting, form the upper strata of shed open by first line hook and harness cord.Hang in the lower comprehensive ring of heald and combined hammer, when shed closed, relied on its weight to play back the effect of combining.When atresia on card at the moment, eedles returns back through plush copper, promotes corresponding staight needle, and staight needle hook end is departed from and griffes, the heald be therefore connected with staight needle and organizine all do not promote, below organizine just sinks to, the lower floor of formation shed open.So the motion of every root organizine is according to porose on card or decide without sky, the Kong Ze on card rolls into according to the designing requirement of decorative pattern and tissue, and therefore the motion of organizine also just meets the requirement of grain pattern and tissue.
The Griffe mechanism of existing jacquard easily appears in opening process the situation that yarn is snapped, and griffes the frequency that moves up and down quickly simultaneously, and operationally machine vibration is very large, and noise is sound especially.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of assembly of griffing of jacquard, the technical problem that the present invention solves how to reduce vibration, prevents yarn from snapping.
Object of the present invention realizes by following technical proposal:
A kind of jacquard griffe assembly, jacquard comprises frame, it is characterized in that, griffing assembly comprises and griffes and griffe frame, described frame of griffing is elongated, described middle part of griffing frame is fixed with rotating shaft, described axis of rotation is connected in frame, the described side griffing frame is positioned at rotating shaft is provided with some fixed heads of griffing successively, described griffe to be fixed on griffe the lower end of fixed head, the described opposite side griffing frame is positioned at rotating shaft is fixed with and makes to griffe chord position and keep the balancing weight of balance in rotating shaft both sides quality, and frame is provided with the drive mechanism that rotating shaft can be driven to carry out back rotation.
Griffing frame has two, is positioned at the both sides of frame, griffe to be positioned at two griffe frame griffe on fixed head, rotating shaft is rotated drive back and forth and is griffed frame and swing back and forth, thus drive and griffe to move up and down, griffe frame is arranged balancing weight and add and griffe the stability of frame when swinging, reduce noise.
Griffe in assembly at above-mentioned jacquard, described drive mechanism comprises rotating disk and two bar linkage structures, described motor is fixed in frame, described dial rotation to be connected in frame and to pass through motor-driven rotation, on described rotating disk, bias is provided with eccentric shaft, two bar linkage structures comprise the drive connecting rod and passive connecting rod that are hinged, described active connecting rod and eccentric shaft hinged, passive connecting rod and rotating shaft are fixed.Drive connecting rod makes the pin joint of itself and passive connecting rod swing up and down with eccentric shaft turns, makes passive connecting rod drive rotating shaft to carry out back rotation.
Griffe in assembly at above-mentioned jacquard, described lower end of griffing fixed head has square opening, upper and lower two hole walls of described square opening have locating slot, spring and the decorative pearl on top of an official cap is provided with in described locating slot, one end and the locating slot groove bottom of described spring are fixed, and the other end and the decorative pearl on top of an official cap are fixed, described in the end winding support of griffing have the fixture block matched with square opening, described fixture block through square opening, the upper and lower end face of fixture block and the decorative pearl on top of an official cap against.Griffe moving up and down Shi Huiyu and receive the tension force effect of yarn, this structure can play cushioning effect when griffing tensioning yarn, and the tension force that yarn is subject to comparatively relaxes, and avoids injury yarn and avoids yarn to be pulled off.
Griffe in assembly at above-mentioned jacquard, the upper and lower end face of described fixture block all has the groove of circular arc, the described decorative pearl on top of an official cap embeds in groove.This structure plays the effect of the location decorative pearl on top of an official cap.
Griffe in assembly at above-mentioned jacquard, described fixture block is also fixed with screw rod, and described screw rod has been threaded nut.Griffe to be positioned at griffe on fixed head time, being all resisted against corresponding griffing on fixed head by griffing two end nuts, griffing griffing stable being positioned on fixed head.
Griffe in assembly at above-mentioned jacquard, described griffing is bar shaped tabular, described rectangular in cross-section of griffing, described upper/lower terminal face of griffing is positioned at the same side and all has chamfering, the described two ends griffing to be positioned at chamfering are all fixed with connecting plate, be positioned at chamfering between two pieces of described connecting plates and be rotatably connected to roller, described in the both ends of the surface up and down of griffing tangent with the roller in corresponding chamfering respectively.Griffing just to have started to contact with yarn until when griffing yarn to mention to the highest or extreme lower position, griffe and have relative movement between yarn, by making yarn and the roller-contact that can rotate that yarn can be prevented to be worn, minimizing yarn and the friction between griffing, avoid yarn to be pulled off simultaneously.
Griffe in assembly at above-mentioned jacquard, the two ends of described roller are all fixed with connecting axle, and the connecting axle being positioned at two ends is each passed through connecting plate, is connected between connecting axle and connecting plate by bearing.Bearing can increase the rotation sensitivity of roller.
Griffe in assembly at above-mentioned jacquard, the two ends of described roller are also fixed with baffle plate, and described baffle plate is rounded, and the diameter of described baffle plate is greater than the diameter of roller.This structure can prevent yarn from snapping between roller and connecting plate.
Griffe in assembly at above-mentioned jacquard, described in the turning of the opposite side of the relative chamfering in upper/lower terminal face of griffing be fillet.
Compared with prior art, the assembly of griffing of this jacquard has the stability added when griffing frame swing, reduces noise and vibration, and the advantage that can prevent yarn from snapping.
