One drive block 34,37 one side of the buffering wheel are protruding with the second drive block 38, have arc-shaped second to delay on another side
Sliding slot 39 is rushed, the second drive block 38 is connected in the first buffering chute 32, and the first drive block 34 is connected to the second buffering chute 39
In；
The sum of radian of first buffering chute 32 and the second buffering chute 39, which is equal to or more than rotating bar 7, makes torsion wire claw 14
By holding tightly to the angle for opening required rotation；
Rotating bar 7 and power input gear 31 are sequentially connected, and rotating bar 7 is also connected to buffering wheel 37 and defeated by bearing 35
Go out in the centre bore of wheel 33.
To increase buffering capacity to adapt to higher requirement, it is preferred that the buffering wheel 37 is three, and three buffering wheels are stacked
It sets together, the second drive block of the wherein buffering wheel of rear stage is connected in the second buffering chute of previous stage, the first buffering
The sum of radian of sliding slot and three the second buffering chutes, which is equal to or more than rotating bar 7, makes torsion wire claw 14 by holding tightly to needed for opening
The angle of rotation.
The course of work and operation principle of the present invention：
Silking process:When motor positive direction rotates, power input gear rotation is driven, since buffering wheel is in tactile at this time
Hair-like state i.e. the second drive block is at the terminal of the first buffering chute, and the second drive block of the buffering wheel of rear stage is in previous
At the terminal of second buffering chute of grade, the first drive block is at the terminal of the second buffering chute, therefore, power input gear
Power be directly transferred to output wheel, output wheel drive wire feeder realizes spinning；And the torsion wire pawl of torsion wire mechanism at this time
Son it is in the open state, therefore lower pawl type tolerance bit slice limitation long tooth rotate from top to bottom, torsion wire mechanism do not generate rotation and
Sliding, although specifically, rotating bar also connect and rotates therewith with power input gear, its steering is opposite with screw thread steering i.e.
It skids between the arrival end and thread of thread segment, and thread segment can not match altogether with thread, therefore torsion wire mechanism does not generate
Rotationally and axially slide.
Torsion wire process:After spinning is to setting length, motor stops rotating forward, and starts reversion and carries out torsion wire action, motor is anti-
When turning, power input gear is driven to rotate backward, buffering wheel is in the rotation of buffer status i.e. the first buffering chute, the first order at this time
The second drive block of buffering wheel slided in the first buffering chute when being back to the beginning of the first buffering chute, the first order it is slow
Second drive block of punching wheel is driven by the beginning of the first buffering chute, at this point, first order buffering wheel is driven rotation, the second level
The second drive block of buffering wheel slided in the second buffering chute of the buffering wheel of the first order, the second of the buffering wheel of the second level
When drive block is back to the beginning of the second buffering chute of first order buffering wheel, the buffering wheel of the second level is driven, the third level
Second drive block of buffering wheel slides in the second buffering chute of the buffering wheel of the second level, and the second of the buffering wheel of the third level passes
When motion block is back to the beginning of the second buffering chute of second level buffering wheel, the buffering wheel of the third level is driven, the first drive block
It is slided in the second buffering chute of the buffering wheel of the third level, the first drive block is back to the second snubber slide of third level buffering wheel
When the beginning of slot, power is transported at output wheel；While buffering wheel is in buffer status, rotating bar is reversed drive and turns round
Screw claw is held tightly, and the upper narrow banking stop limitation long tooth of pawl type rotates from lower to upper, while being pushed in the thread segment of rotating bar
Lower long tooth slides in and out along the narrow banking stop of upper pawl type；Specifically, the thread segment of rotating bar matches with thread altogether, due to upper
The narrow banking stop limitation long tooth of pawl type rotates from lower to upper, therefore the thread segment of rotating bar can only push sleeve forward by thread
It is mobile, and collet and rotating bar position are motionless, it is long while torsion wire claw embraces iron wire to make torsion wire claw embrace iron wire
Tooth is detached from the narrow banking stop of upper pawl type, and torsion wire mechanism generates rotation, torsion wire is carried out, since the number of turns of torsion wire is according to actual conditions
Depending on, that is, the number of turns turned round is uncertain, therefore, unilateral bearing is provided on the wire-feeding transmission mechanism of wire feeder, therefore i.e.
The buffer status of buffering wheel at this time is set to be over, when power is transferred to wire feed power input gear from output wheel, unilateral bearing
Skidding makes two wire feed rolls not generate rotation, therefore when torsion wire mechanism is in torsion wire, wire feeder not wire feed；Reach a motor simultaneously
Torsion wire mechanism and wire feeder are driven, and is independent of each other each other.
When torsion wire mechanism generates rotation progress torsion wire, cam rotation, when the protruding end of cam is with triggering end in contact, triggering
End is gradually lifted, spring contraction, and the driving section arc of the lever other end moves down, and sliding block cutter cuts off tied silk.Work as triggering end
After the protruding end highest end in contact of cam, since there are normal throws, while under the pushing tow of spring, the triggering end quilt of lever
It pushes, at the same time, the rapid uplink in driving section of the lever other end avoids again to make sliding block cutter be lifted reset rapidly
Sliding block cutter blocks filament mouth when wire feed.
When cutting off iron wire progress torsion wire, often iron wire is influenced to generate deflection, deflection in two reinforcing bar intersections by torsion
Iron wire will produce the phenomenon that reset causes to loosen after tightening, the phenomenon that avoid this loosening, set up in the side of tightening
Have upper gear door and lower block door, specifically, when being tightened clockwise, upper gear door and lower block door respectively to be rotated up with downwards
The iron wire of rotation is stopped, it is made not generate deflection, ensures that torsion wire mechanism can be tightened smoothly without generating loosening, after tightening,
Since lower receipts silk mouth can be rotated down along hinged place, when reinforcing-bar binding machine is detached with iron wire, lower receipts silk mouth generation is kept away
It allows, reinforcing-bar binding machine is made smoothly to be detached with iron wire, avoid the occurrence of the phenomenon that iron wire is blocked and cannot be detached.
Reseting procedure:Motor can enter positive direction rotary state again from reversion immediately after the completion of torsion wire, at this point, torsion wire pawl
Son is by holding tightly to opening, and lower pawl type tolerance bit slice limitation long tooth or short tooth rotate from top to bottom, while in the screw thread of rotating bar
Long tooth or short tooth extend the deadline bit slice slid inward along lower pawl type under section pull；Specifically, motor positive direction rotates, the spiral shell of rotating bar
Line section is spun out from thread, to make torsion wire claw open, due to lower pawl type tolerance bit slice limitation long tooth or short tooth
It rotates from top to bottom, therefore long tooth or the short tooth pawl type under extend the deadline bit slice slid inward under the thread segment pull of rotating bar,
At this point, if short tooth extends the deadline bit slice slid inward along lower pawl type, since the pull stroke of thread segment is more than short tooth along lower pawl
Formula extends the deadline the stroke of bit slice slid inward and shorter than long tooth extends the deadline the stroke of bit slice slid inward along lower pawl type, therefore in short tooth
When slid inward is to end, short tooth can be separated from lower pawl type tolerance bit slice, at this point, torsion wire mechanism generates rotation, until long tooth
It is in contact with lower pawl type tolerance bit slice, such be advantageous in that can ensure what two open torsion wire claws were set in one
On position, make that torsion wire claw accurately smoothly can hold iron wire tightly each time and realization tightens.
Until when thread segment screws out thread completely, long tooth is stuck on lower pawl type tolerance bit slice, and sleeve stops slid inward,
At this point, although rotating bar also connect and rotates therewith with power input gear, it turns to i.e. thread segment opposite with screw thread steering
Arrival end and thread between skid, and thread segment can not with thread match altogether, therefore torsion wire mechanism do not generate rotation and
It slides axially.And at this point, triggering end is in the front in normal throw face, sliding block cutter is in the top of filament mouth, ensures wire feed
Process is smooth not to be blocked.
In torsion wire claw by holding tightly to while opening, buffering wheel is then resetted from buffer status to triggering state, this process
With the buffer status course of work on the contrary, no longer describing herein.It should be noted that the first buffering chute and three the second snubber slides
The sum of radian of slot, which is equal to or more than rotating bar, makes torsion wire claw by holding tightly to rotated angle is opened, and can ensure to turn round in this way
After screw claw is opened completely, wire feeder carries out wire feed again, ensures to stablize when torsion wire and continuously, avoids damaging, when
It completes after one-step bundling with tying up next time can be carried out.
The resetting spring is constantly in compressive state after being installed to spring storehouse, and action of reset spring is：
1, after thread segment screws out thread completely, the arrival end and thread of thread segment are when skidding, in the work of resetting spring
Under, thread segment remain with thread be in close contact i.e. the arrival end of thread segment and thread holding slipping state without
The arrival end of thread segment leaves thread, causes when rotating bar turns to identical as thread segment steering, thread segment cannot connect with thread
It picks up and.Therefore when setting resetting spring is advantageous in that the steering when rotating bar is changed to identical as thread segment steering, screw thread
The arrival end of section can cooperate rapidly with thread, make sensitiveer, the working efficiency higher of present invention work.
2, when short tooth, which is separated from lower pawl type, extends the deadline bit slice, under the action of resetting spring, it can guarantee that torsion wire mechanism produces
Raw rotation makes long tooth and lower pawl type tolerance bit slice be in contact, and avoids the frictional force between thread segment and thread too small, leads to thread
Outer barrel cannot be driven to rotate, keep work more stable.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, it is other it is any without departing from the spirit and principles of the present invention made by changes, modifications, substitutions, combinations, simplifications,
Equivalent substitute mode is should be, is included within the scope of the present invention.
