On the second axle 8, bending needing mechanism 1 connects first axle 2 by crank and rocker mechanism 3 to bending needing mechanism 1.
Crank and rocker mechanism includes crank, rocking bar, connecting rod, and crank is fixed on 2 front end of first axle, and rocking bar is fixed on the second axle
8 centre, between the first sleeve bracing frame 17 and support base 16, the rocking tendency of rocking bar at 65 ° or so, crank rotation
There can be relative displacement between plane and the plane that rocking bar is waved.
Dials 20 be arranged on 12 another part front end of support, its periphery altogether with 608 pins, have one section in the middle of every pin
Groove, is internal gear in the middle of dials 20, has 272 teeth, and dials can rotate.
Gear shaft 19 be arranged on support 12 in the middle of, its number of teeth be 17, engage with the internal gear of dials 20, gear shaft 19 by from
Motor is directly rotated.
Mair motor is 38 with the rotary speed ratio from motor：1, turning from motor is controlled with the speed of mair motor and position
Speed.
The method of work of the present invention is as follows：
First axle 2 is directly rotated by mair motor, and the crank in first axle 2 also and then rotates, so as to drive rocking bar to do
Swing, so that bending needing mechanism 1 also does oscillating motion, with the swing of bending needing mechanism 1, looper enters the groove of pin on dials 20
It is interior, latch needle mechanism 7 is entered then along groove, withdraw further along groove, finally leave groove.
Gear shaft 19 by being directly rotated from motor, as the gear on gear shaft 19 is nibbled with the internal gear on dials 20
Close, so as to drive dials 20 to rotate, as gear ratio is 38：1, therefore also play the effect of deceleration.
First roller gear 15 is rotated, the groove side of bearing 10 and the first roller gear 15 with the rotation of first axle 2
Face contacts, and moves forward and backward with the rotation of the first roller gear of roller gear 15, before bearing 10 also drives the 3rd axle 9 to do simultaneously
After move along a straight line, the 3rd axle 9 can provide proal thrust for the second axle 8, and the thrust that the second axle 8 is moved backward is then by bullet
Spring is provided, and would not pass to the 3rd axle 9 by the rotation of the second axle of crank handle turns 8 so that the bearing on the 3rd axle 9 can be always
Sustained height is kept, so that bearing 10 is moved forward and backward and is not affected, as the second axle 8 is moved forward and backward, bending needing mechanism 1 also does
Move forward and backward.
Second roller gear 13 is rotated with the rotation of first axle 2, the bossing of clutch plate 14 and the second Cylinder Gear
The groove contact of wheel 13, rotates back and forth with the rotation of the second roller gear 13, by synchronous belt mechanism (by big synchronous pulley
4th, ferry boat mechanism 5, small synchronous pulley 6 are constituted) by the angle enlargement for rotating back and forth and pass to latch needle mechanism 7 so that crochet hook machine
Looper in structure 7 is rotated upwardly and downwardly, and which is rotated upwardly and downwardly and is moved to matching, as looper enters latch needle mechanism 7, hook with bending needing mechanism 1
Pin is just rotated down, it is possible to hooked downwards the line on looper, as looper is back moved, crochet hook is rotated up, in looper
Origin-location has been returned to before leaving latch needle mechanism 7, has waited entering next time for looper.
The ferry boat mechanism 5 of synchronous belt mechanism is arranged on the lower section of big synchronous pulley 4 and 6 line of centres of small synchronous pulley, so as to
Increase the angle that Timing Belt coats small synchronous pulley 6.
Mair motor and between motor by controlling reaching position relationship and rotating ratio, the position relationship for being reached and turn
Speed is moved forward and backward with looper and can be matched than causing pin on dials 20 to rotate at a slow speed, and looper is soon into the recessed of the pin on dials 20
When in groove, just move backward, and be consistent with the speed of pin on dials 20 so that looper always in groove, until curved
Pin withdraws just to travel forward from groove and returns to origin-location.
The present invention is designed using more than, makes the looper and crochet hook motion of Linking machines electric by two respectively with dials rotary motion
Machine drives, and two motors are realized the position relationship of two motors and turn degree ratio by the method for principal and subordinate's motor control, so that structure
Become compacter, decrease the equivalent moment of inertia on the part and motor of transmission, so that Linking machines can be transported at a high speed
Row and quick startup, while reduce noise.
