Description
Technical field
The utility model relates to a kind of cutter of automatic bookbinding machine and its linkage mechanisms, belong to stacked in bookbinding operation
The permanent binding technique field of paper or register.
Background technique
Currently, automatic bookbinding machine used by bookbinding to paper such as folio, bill, archives, this binder is realized
The automation of forwarding starts corresponding operation by operation panel as long as bookbinding file is placed on the table, can be with
Punching, Pipe Cutting and the several processing steps such as bookbinding that press once are completed, labor intensity is greatly simplified, improves bookbinding matter
Amount.
Existing automatic bookbinding machine is as shown in Figure 1, and cutter mechanism 1 thereon is fixed on middle platen 102.Such as Fig. 2 and Fig. 3
Shown, cutter mechanism 1 is constituted by successively going here and there the pull rod 3 covered in shaft 2, shift fork 4, seat 5 and rocking bar 6.Such as Fig. 1 and Fig. 3 institute
Show, semiaxis 105 is equipped in the lifting guide pillar 16 of binder, and the lower end of semiaxis 105 is equipped with pin hook 104；Seat 5 is fixed on middle platen
On 102；One end of pull rod 3 is hinged in shaft 2, and the other end connects tension spring 7；One end of rocking bar 6 is hinged in shaft 2, another
End is stretched out；One end of shift fork 4 is hinged in shaft 2, and the other end couples with cutter and (shows in figure).When work, led in lifting
Its pin hook 104 of the semiaxis 105 risen in column 16 with lifting guide pillar 16, which lifts, rotates forward rocking bar 6, and shift fork 4 is by with just
Push the blade pairing of cutter to cut off plastics riveting pipe 8 after to rotation, pull rod 3 overcomes the pulling force of tension spring 7 to rotate forward at this time；In
Its pin hook 104 of the semiaxis 105 declined in lifting guide pillar 16 with lifting guide pillar 16 leaves rocking bar 6, and tension spring 7 drives pull rod 3 reversed
Rotation, shift fork 4 is pushed the blade of cutter to separate with after rotating backward, so that plastics riveting pipe 8 is fallen.Its there are the problem of
It is: one, due to being only to drive pull rod 3 and shift fork 4 to realize by tension spring 7 when the blade of cutter separates, after tension spring 7 is used for multiple times
Pulling force is easily varied or fails, therefore it is not in place to cause the blade of cutter to separate, and influences plastics riveting pipe 8 and falls and subsequent cut again
Pipe.Two, when the pin hook 104 of the lower end of semiaxis 105 rises because of contact surface small (substantially line contact) and not with the other end of rocking bar 6
It matches and is easy to appear skidding, influence the rotation of rocking bar 6.Three, the mechanism element for completing the positive decommuntation of cutter is more, occupied space
And influence motion credibility.Four, the not high influence commutation of the displacement accuracy that semiaxis rises and cutter mobile accuracy.In short, part is more
And reliability and precision be not high.
Summary of the invention
Technical problem to be solved by the utility model is: making the operation of the cutter linkage mechanism of existing automatic bookbinding machine can
It increases by property and precision.
The technical solution that the utility model proposes to solve above-mentioned technical problem is: a kind of cutter gear of binder
Structure, including cutter assembly and linkage mechanism, the cutter assembly include the knife rest being fixed on the middle platen of the binder, In
Moveable blade and the block being fixed on the knife rest on the knife rest, the blade and block can relative to each other pairing and
Separation, the linkage mechanism includes reversing mechanism；The reversing mechanism includes being fixed on consolidating on the middle platen of the binder
Reservation and the shaft being threaded through in fixing seat are equipped with the shift fork positioned at the fixing seat side in the shaft；The shift fork
One end couple with the blade；It is characterized by: the linkage mechanism further includes the lifter rack of the binder, the liter
The bottom end of drop rack gear is equipped with pin shaft and extends to the middle platen hereinafter, being also equipped in the shaft positioned at the fixation
The shifting block of the seat other side；The shifting block is in crescent, and one end of crescent is equipped with pulley.
When the work of the utility model, when lifter rack decline, the bottom end of the lifter rack contacts and pushes
The pulley simultaneously pushes the shifting block to rotate forward along the shaft, and the shift fork also rotates forward simultaneously and pushes the blade
It moves forward and is separated with the block, the pin shaft enters in the crescent intrados of the shifting block, and the plastics riveting pipe is fallen
Enter the gap between the blade and block；When the lifter rack rises, the cunning is left in the bottom end of the lifter rack
Wheel, the pin shaft push the other end of the crescent of the shifting block aside upwards and the shifting block are pushed to rotate backward along the shaft,
The shift fork also rotates backward simultaneously and pushes the blade to move backward and cut off the plastics riveting with the block pairing
Pipe.
The cutter linkage mechanism of the utility model binder, 1) since the lifter rack of binder itself directly being extended simultaneously
So that its bottom end is extended to middle platen hereinafter, and design unique crescent shifting block, using the bottom end and its pin shaft of lifter rack come
It pushes directly on the forward and reverse rotation of shifting block completion and (directly stirs the one end of shifting block crescent, lifting when declining in lifter rack bottom end
The pin shaft of rack gear bottom end directly stirs the other end of shifting block crescent when rising), as long as therefore shifting block one action
The effect for completing two parts of rocking bar and pull rod of existing binder cutter mechanism, not only reduces part and its occupied space,
And the commutation of cutter is directly realized by by the lifter rack of binder itself, motion credibility is higher.2) lifter rack is utilized
Bottom end and pin shaft form two kinds of motive forces up and down to shifting block, it can be ensured that form reliable turn to shifting block and its coaxial shift fork
It is dynamic, avoid existing the drawbacks of being only easy failure by spring force.With shifting block crescent when 3) declining due to lifter rack bottom end
One head sheave and what pin shaft formed the other end intrados of shifting block crescent when rising is face contact, therefore be not easy to beat
It is sliding, it is ensured that thrust is reliable.4) since the displacement accuracy of lifter rack raising and lowering is higher than the existing position risen by semiaxis
Precision is moved, therefore utilization lifter rack raising and lowering directly forms the precision of the Double-directional rotary of shifting block and its coaxial shift fork
It is necessarily higher than the existing precision for rising by semiaxis and driving shift fork rotation, to improve cutter opening and closing precision.
Further improvement is that the bottom end of the lifter rack forms corner cut.
Further improving is that the pulley is bearing.
Further improving is that the shift fork is additionally provided with spring.In this way, spring can be passed through when lifter rack rises
Reset pulling force and pin shaft dual motive force is formed to stirring for shifting block, be more conducive to being rapidly completed cutting plastics riveting pipe.
Further improving is that the lifter rack is engaged with the gear of the lifting motor output shaft end of the binder.
