Embodiment
Under the technical solution of the utility model is described in further detail by specific embodiment and with reference to accompanying drawing.
Embodiment 1：
In the embodiment shown in Fig. 1, Fig. 2, a kind of tripping mechanism, including：
Support 1, the support for knotting and threading off is realized for supporting；
Knotter jaw 2, knotter jaw 2, which is arranged on support 1, to be used to realize knotting fake；
Hook jaw mechanism 3, it is connected to realize that rope hose tool knots with knotter jaw 2；
Tool arm 4, for installing cutter and realizing dropout；
It is provided with tool arm 4 for forcing to take off from the surface of knotter jaw 2 by fake and drawing knot during dropout
Tight pressure dropout breach 5.
Tool arm 4 includes rotating tool arm 6 and fixed tool arm 7 (see Fig. 3), forces 5 curved structure setting of dropout breach solid
On stationary knife arm 7.
Fixed tool arm 7 is set with rotating the integral type of tool arm 6.
Fixed tool arm 7 is in circular arc v-shaped structure with rotating the junction angle of tool arm 6 and setting, and rotates tool arm 6 close to the one of angle
Side is provided with tool arm rib exterior feature 8.
Tool arm 6 is rotated to be connected with support 1 by rotary shaft 9.
Knotter jaw 2 is arranged on the inner side of tool arm 4 and surrounded by tool arm 4, and hook jaw mechanism 3 is arranged on the lower end of knotter jaw 2 and set
Put in the top of tool arm 4.
The knotter jaw bevel gear 10 for coordinating with actuator is provided with knotter jaw 2.
Hook jaw mechanism 3 includes hook pincers 11 and hook pincers pressing plate 12, and hook clamps one end relative with jaw on 11 and is provided with roller 13；
Hook pincers pressing plate 12 is arranged on support 1, and hook pincers pressing plate 12 is located at the outside of hook pincers 11 in semi-surrounding structure ring, and hook is clamped on pressing plate 12
It is provided with hook pincers pressing plate limiting plate 14 (see Fig. 4).
Knotter is a spatial compounding transmission mechanism, and it is endless to be provided with two sections be radially staggered in the card of drive gear disk
Full bevel gear, one section is straight bevel gear, and one section is helical bevel gear.Wherein straight bevel gear engages with knotter jaw bevel gear,
Driving knotter jaw complete around pull make and sting bundle rope action.Helical bevel gear is engaged with worm screw bevel gear, and driving folder cheese is completed
Press from both sides rope action.The groove cam of control twine knife frame action is set between the wheel hub of driving fluted disc and incomplete bevel gear, driven
Moving knife arm completion conductor rope, cut rope and the action of de- rope.
Tool arm 4 forms for hot investment casting, rotates irregular tool arm rib exterior feature 8 on tool arm 6 and mainly completes conductor rope, so that
Bundle rope is reliably ridden on knotter jaw 2.Pressure dropout breach 5 on the fixation tool arm 7 of tool arm 4 is act as fake from knotter jaw
Force to take off and be primarily used to completion with the part of twine knife composition and cut rope in 2 surfaces.Support forms for hot investment casting.
The knotting principle 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, due to
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
Reliably ride on knotter jaw, completion send rope and takes rope action.2. folder rope：Drive gear disk now engages rotation with worm screw bevel gear
Turn, so as to drive folder cheese to rotate by worm drive shaft, worm screw.When pressing from both sides cheese and rotating 1/8 circumference, sending what toggle was sent
Rope clamp enters and pressed from both sides the space between the folder rope moving plate that cheese is used cooperatively, and bundle rope is firmly jammed.3. knot：Drive gear
Disk now engages rotation with knotter jaw bevel gear, and knotter jaw make around pulling, after knotter jaw rotates 3/4 circumference, knotter jaw
Upper formation fake, while the roller of hook pincers afterbody just reaches support roller guide assembly, drives hook pincers to open, and completes hook pincers and stings
Tie rope action.Send toggle return and rope is put into and just go in the breach of folder cheese above, as rope knot next time before
Head.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.On tool arm
Pressure dropout breach fake is forced to take off from knotting nozzle surface, and tense knot during dropout, most restrict at last
Draw out to form a knot in fake in one end of son.
The tripping mechanism, the matching relationship between knotter jaw, hook jaw mechanism and tool arm is dexterously make use of, using on tool arm
The pressure dropout breach coil that makes to wind smoothly taken off from knotter jaw, the tripping mechanism, do not increasing other mechanisms
Under the premise of, plastic emitting buckle structure is designed using existing component, simple in construction, ingenious in design, dropout effect is good.
