See Fig. 1, present embodiment comprises motor 1, transmission main shaft 2, connector 3, axis 4, axis traverse mechanism 5, axis rotating mechanism 6, roll rotating mechanism 7, two rolls 8 and mounting panels 10.Said motor 1 comprises decelerator, and motor 1 is fixed on the frame, and said transmission main shaft 2 is connected with the output shaft of decelerator, and transmission main shaft 2 is supported by bearing 13, and bearing 13 is by the bearing pedestal 13-2 support that is fixed on the frame, and the top of bearing 13 is provided with bearing cap 13-1.Said roll 8 comprises coiling main shaft 8-1 and coiling front axle 8-2, is connected by shaft coupling 9 between the two, and the front end of each coiling front axle 8-2 is fixed with coiling nozzle 11.
Said mounting panel 10 is provided with two coiling axis holes of central axis hole and the setting of symmetrical central axis hole, and said axis 4 and two rolls 8 respectively pass through in the axis hole of Bearing Installation correspondence on mounting panel 7.
The rear end face of said axis 4 is provided with connecting hole, and an end of said connector 3 is connected in the connecting hole of axis 4 through bearing.
Said axis traverse mechanism 5 comprises crank 5-1 and connecting rod 5-2, and crank 5-1 is fixed on the transmission main shaft 2, is connected by No. 1 bearing pin 5-3 between the end of connecting rod 5-2 and the crank 5-1, is connected by No. 2 bearing pin 5-4 between the other end of connecting rod 5-2 and the connector 3.The pin shaft hole that is used to connect said No. 1 bearing pin 5-3 on the crank 5-1 of said axis traverse mechanism 5 is strip hole 5-1-1 radially.The stroke of roll 8 is controlled by the radius of crank 5-1, and the stroke of roll 8 is the twice of crank 5-1 radius, and pin shaft hole is the radius of the conveniently adjusted crank 5-1 of strip hole 5-1-1 radially, with the coiling of the motor stator winding that adapts to different length.
Said axis rotating mechanism 6 comprises end face ring grooved cam 6-1, rack-and-pinion and bevel gear pair; Above-mentioned end face ring grooved cam 6-1 is fixed on the transmission main shaft 2; Tooth bar 6-3 in the rack-and-pinion is automatically connected on the tooth bar guide holder 14, and tooth bar guide holder 14 is fixed on the frame, and tooth bar 6-3 moves forward and backward along the guide rail on the tooth bar guide holder 14; The return idler 6-2 of end face ring grooved cam 6-1 is fixed on the termination of tooth bar 6-3; Return idler 6-2 moves in the end face annular groove of end face ring grooved cam 6-1, and driven gear 6-4 in the rack-and-pinion and the drive bevel gear 6-5 in the bevel gear pair are on the same axle 12, and this axle 12 is by rack support.For loose key is connected, it is dive key or feather key that loose key connects used key 4-1 between driven wheel of differential 6-6 in the bevel gear pair and the axis 4, and loose key connects only to be done circumferentially fixingly to driven wheel of differential 6-6, can not bear axial force.
Said roll rotating mechanism 7 comprises that the gear wheel 7-1 that is fixed on the axis 4 is identical with two and is separately fixed at the pinion 7-2 on the two coiling main shafts 8 that pinion 7-2 all meshes with gear wheel 7-1.Said gear wheel 7-1 and pinion 7-2 all adopt helical gear.
Transmission main shaft 2 drives connector 3 through axis traverse mechanism 5 and then drives axis 4 makes the front and back back and forth movement; And through the 6 intermittently rotations of driving axis 4 of axis rotating mechanism; Axis 4 passes through mounting panel 10 and drives two coiling main shafts, 8 work front and back back and forth movements, and rotates synchronously through two coiling main shafts 8 of roll rotating mechanism 7 drivings.
When transmission main shaft 2 rotations, crank 5-1 and end face ring grooved cam 6-1 rotate.Back and forth movements before and after crank 5-1 does through connecting rod 5-2 driving connector 3 are made the front and back back and forth movement by connector 3 driving axis 4 again, drive mounting panels 10 by axis 4 and make the front and back back and forth movements, and mounting panel 10 drives two rolls 8 again and makes the front and back back and forth movement.End face ring grooved cam 6-1 promotes tooth bar 6-3 through return idler 6-2 and moves, and the driven gear 6-4 in the rack-and-pinion drives drive bevel gear 6-5 and driven wheel of differential 6-6 rotation, and then drives axis 4 rotations.Gear wheel 7-1 on the axis 4 drives the pinion 7-2 rotation on two rolls 8 simultaneously, rotates synchronously thereby drive two rolls 8.
Since between the driven wheel of differential 6-6 in the bevel gear pair and the axis 4 for loose key is connected, so during axis 4 work front and back back and forth movements, driven wheel of differential 6-6 can remain the engagement with drive bevel gear 6-5, does not influence the rotation of axis 4.Because axis 4 is respectively to be connected with mounting panel 10 through bearing with two rolls 8, makes back and forth movement so mounting panel 10 can drive two rolls 8, does not influence the rotation of two rolls 8 again.Because bearing is connected between connector 3 and the axis 4, so the torque of axis 4 can not pass to connecting rod 5-2.
The corner of roll 8 or coiling nozzle 11 except with the rise or backhaul mutually of end face ring grooved cam 5-1 outside the Pass; Also with axis traverse mechanism 5 middle gear tooth bar pairs in gearratio, the gearratio of big pinion in the roll rotating mechanism 7 of gearratio, bevel gear relevant, any one factor wherein of promptly changing all can change the corner of roll 8.Confirm first of confirming in four influencing factors of concrete angle of roll 8, confirm the value of last influencing factor again according to the requirement of number of slots.For example: reserve distance, the gearratio in the rack-and-pinion of rise and the backhaul of the end face ring grooved cam 6-1 in the axis traverse mechanism 5, the gearratio of bevel-gear sett earlier, calculate the gear ratio value of the big pinion in the roll rotating mechanism 7 at last.
