Fig. 1 is traditional left and right sides header phase-regulating mechanism figure.
Fig. 2 is the B-B view of Fig. 3.
Fig. 3 is a driver composition of the present utility model.
A among Fig. 4, b, c are respectively 3 kinds of forms of octavo finished product folding card.
The specific embodiment
As shown in the figure: the nut 13 that cooperatively interacts is arranged on screw mandrel 12, nut 13 is connected with fairlead 15, on fairlead 15, utilize bearing that the opposite phase adjusted helical gear that fuses 16,14 of rotation direction is installed, helical gear 16,14 meshes with jack knife gear 8 and crochet hook gear 9 respectively, connect the mechanism that handwheel 11 or drive or dial or other can rotary screw rods in the end of screw mandrel 12, the scale dial plate is arranged on handwheel 11.Jack knife gear 8 is positioned on the main shaft 6 with crochet hook gear 9, and jack knife gear 8 fixedlys connected with the adapter sleeve 3 on being enclosed within main shaft 6, and adapter sleeve 3 is connected with jack knife frame 1, and adapter sleeve 3 can rotate relative to main shaft 6 together with jack knife gear 8.The fixedly connected pinion stand 7 in the middle part of crochet hook gear 9, pinion stand 7 is fixedly installed on the main shaft 6, and crochet hook gear 9 must rotate with main shaft 6.In the outside of screw mandrel 12 sleeve 31 is arranged, limited block 32 is installed on sleeve 31, on fairlead 15, chute is arranged, limited block 32 embeds in the chute, when rotary screw rod 12, when making nut 13 and fairlead 15 mobile vertically, can control its axially movable distance by the length of chute.Side near handwheel 11 on screw mandrel 12 has axle sleeve 34, the holding screw 10 that can be screwed in the screwed hole that is arranged on the screw mandrel 12 is arranged on axle sleeve 34, this holding screw 10 is used to control the rotation situation of handwheel 11, when holding screw 10 was screwed in the screwed hole on the screw mandrel 12, then screw mandrel 12 can not rotate.Submission barrel 18 is installed on main shaft 6, on submission barrel 18, crochet hook rotating shaft 17 is installed equably, jack knife rotating shaft 2 is installed on jack knife frame 1 equably.One end of adapter sleeve 3 is positioned at the middle part of jack knife gear 8, at the adapter sleeve 3 and the end face of the connecting portion of jack knife gear 8 connecting plate 5 of the effect of connection has been arranged, and during installation, can utilize two row's screws to be screwed into respectively on jack knife gear 8 and the adapter sleeve 3, and both are tightened together.
Among the figure 4 is for to be installed on the axle bed on the wallboard 35 with main shaft 6, adapter sleeve 3, and 33 for installing the support of axle sleeve 34.
When needs are adjusted the phase place of left and right sides header, unclamp holding screw 10 earlier, the handwheel 11 of rotating band scale dial plate, make screw mandrel 12 rotations, driving the nut 13 and the fairlead 15 that match with it moves vertically, (rotating in a circumferential direction) because of there being feather key to limit it on the fairlead 15, drive duplex helical gear 14 again, 16 also axially move, because duplex helical gear 14,16 rotation direction is opposite, force the jack knife gear that is engaged with 8 and crochet hook gear 9 to rotate in opposite direction, so drive the also variation round about of phase places that crochet hook rotating shafts 17 are arranged in 3 jack knife rotating shafts 2 and 3 on the submission cylinder 18.Cut-off knife gear 19 meshes with crochet hook gear 9 in addition, there is not phase place to change between them, the jack knife gear 8 coaxial with crochet hook gear 9 then is meshed with clamping plate gear 20, phase place between them does not change yet, what change only is to be installed on the cut-off knife in the jack knife rotating shaft 2 and to be installed on phase place between crochet hook and jack knife, clamping plate in the crochet hook rotating shaft 17, changes the purpose of rolling over obedient finished product the upper and lower length thereby reach.
A among Fig. 4 is the two-layer isometric situation of folding card; B is longer than the situation of lower floor for the upper strata of folding card; C is longer than the situation on upper strata for the lower floor of folding card.
