Knotter jaw open-and-close mechanism is an important mechanism in knotter, is the key mechanism to knot.Knotter is
Between composite driving mechanism, and knotter jaw open-and-close mechanism is as important mechanism therein, and the cooperation of itself and drive gear disk realizes
The folding of knotter jaw, drive gear disk form for hot investment casting, set two sections of incomplete bevel gears being radially staggered in card, and one
Section is straight bevel gear, and one section is helical bevel gear.Wherein straight bevel gear engages with knotter jaw bevel gear, and driving knotter jaw is complete
Into around pull make and sting bundle rope action.Helical bevel gear engages with worm screw bevel gear, and driving folder cheese completes folder rope action.Driving
The groove cam of control twine knife frame action is set between the wheel hub of active toothed disk and incomplete bevel gear, and driving tool arm is completed to lead
Restrict, cut rope and the action of de- rope.Tool arm in knotter is provided with tool arm rib exterior feature, and wide irregular tool arm rib is mainly that completion is led
Rope, so that bundle rope is reliably ridden on knotter jaw.It is additionally provided with tool arm and forces dropout breach, it is act as fake from beating
Knot nozzle surface is forced to take off, and the part of twine knife composition is primarily used to completion and cuts rope.
Support in the knotter jaw open-and-close mechanism forms for hot investment casting, and it is respectively line shaft to have five axis holes in frame
Hole, twine knife arm axle hole, knotter jaw axis hole, worm-drive axis hole and folder cheese axis hole, are in space antarafacial between each axis hole axis
Relation, especially worm-drive axis hole and knotter jaw axis hole have double angles.Knotter delicate structure itself, each mechanism height essence
Standard coordinates, and the angle between each axis hole needs strict guarantee could be so that knotter reliably completes knotting action.
The principle of the knotter jaw open-and-close mechanism during the knotting of knotter is as follows：
1. send rope and take rope：Send toggle to restrict and be sent to the gap position for pressing from both sides cheese, because bundle rope has certain load, so
Rope is slided to bottom land in the presence of load force along tool arm rib exterior feature groove, so that bundle rope is reliably ridden on knotter jaw, it is complete
Acted into sending rope and taking rope.
2. folder rope：Drive gear disk now engages rotation with worm screw bevel gear, so as to be driven by worm drive shaft, worm screw
Press from both sides cheese rotation.When pressing from both sides cheese and rotating 1/8 circumference, moved sending the rope clamp that toggle is sent to enter with pressing from both sides the folder rope that is used cooperatively of cheese
Space between piece, bundle rope is set firmly to be jammed.
3. knot：Drive gear disk now engages rotation with knotter jaw bevel gear, and knotter jaw carries out, around work is pulled, working as knotting
After mouth rotates 3/4 circumference, fake is formed on knotter jaw, while the roller of hook pincers afterbody just reaches support roller guide assembly,
Drive hook pincers to open, complete hook pincers and sting bundle rope action.Send toggle return and rope is put into just go to above folder cheese lack
In mouthful, as fag end knot next time before.
4. cut rope：Drive gear disk is rotated further, and the grooved cam of drive gear disk drives tool arm to swing completion and cuts rope.Knife
Fake is forced to take off by the pressure dropout breach on arm from knotting nozzle surface, and tenses knot during dropout, finally
One end of rope is drawn out in fake to form a knot.
The knotter jaw open-and-close mechanism, by mutual to support, drive gear disk, knotting nozzle mechanism and hook jaw mechanism
Connection matching relationship carry out ingenious combination, mutually order interlocks between each mechanism, and what is be radially staggered in drive gear disk sets
Straight bevel gear and helical bevel gear are equipped with, straight bevel gear is engaged with knotter jaw bevel gear, and driving knotter jaw is completed around pulling
Make and sting bundle rope action, helical bevel gear is engaged with worm screw bevel gear, and driving folder cheese completes folder rope action, and driving tool arm is completed
Conductor rope, cut rope action.The knotter jaw open-and-close mechanism, in the coherent performance of each process that drive gear disk rotation order is completed to knot
Good, when drive gear disk engages with knotter jaw bevel gear to be rotated, knotter jaw is carried out under the drive of drive gear disk around pulling
Make, after knotter jaw rotates 3/4 circumference, fake is formed on knotter jaw, while the knotter jaw folding roller of hook pincers afterbody just arrives
Up in roller guide groove, drive hook pincers to open, complete hook pincers and sting bundle rope action.
The knotter jaw open-and-close mechanism, driving effect is good, and the position of roller guide groove is set rationally, just in knotter jaw
After rotating 3/4 circumference, knotter jaw folding roller is just reached inside roller guide groove, and driving hook pincers open, and action is coherent, folding
Flexibly, open accurate.
