A kind of efficient paper pressing device used in paper press
The present invention relates to press, the efficient paper pressing device used in specifically a kind of paper press.
The machine of printing word and image.Modern printing machine it is general by locing up, inking, impressing, paper carrying (including folding) etc.
Mechanism is constituted.Its operation principle is：Printing plate is made in the writings and image that will first print, and fills on the printer, then by people
Work or printing machine are coated on ink in the place for having writings and image on printing plate, then are directly or indirectly transferred to paper or other printings
On thing (such as textile, metallic plate, plastic cement, leather, plank, glass and ceramics), so as to copy and printing plate identical printed matter.
The invention and development of printing machine, the propagation for human civilization and culture play an important roll.
Existing paper press is before printing, it is necessary to first be cut body paper；When cutting, it is necessary to which body paper is carried
To cut paper platform, then paper is compressed with paper pressing device, then cut.Existing paper pressing device is typically using left and right two
Individual Driven by Hydraulic Cylinder pressing plate is compressed to paper.But, the platen of this paper pressing device is less efficient, and can not disappear well
Except the fold on paper, so as to cause paper formation degree undesirable.

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer in Fig. 1~3, the embodiment of the present invention, the efficient paper pressing device used in a kind of paper press, including framework
1；The bearing plate 11 for placing paper is provided with the framework 1, the both sides of bearing plate 11 are fixed with sliding block 111, sliding block 111
Vertical section to be T-shaped, the chute matched with sliding block 111 is offered on the intracavity sidewall of framework 1, sliding block 111 is slided and is connected to
In chute；The both sides of the bearing plate 11 are symmetrically arranged with screw mandrel 2, screw mandrel 2 through bearing plate 11 and with the spiral shell on bearing plate 11
Pit (not shown) is engaged, and the lower rotation of screw mandrel 2 is connected and fixed on the bearing block 22 of the inner chamber bottom plate of framework 1, screw mandrel 2
Top be provided with limited block 21, the bottom bar body periphery of screw mandrel 2 is fixed with driven wheel of differential 23；The intracavity bottom of framework 1
Center is provided with dual-axle motor 3, and dual-axle motor 3 is arranged on motor cabinet 32, the end of the both sides power transmission shaft 31 of dual-axle motor 3
Portion is fixed with the drive bevel gear 311 being meshed with driven wheel of differential 23, when dual-axle motor 3 is rotated, and drives drive bevel gear
311 rotate, and drive bevel gear 311 engages drive driven wheel of differential 23 with driven wheel of differential 23 and rotated, so as to drive 2 turns of screw mandrel
Dynamic, screw mandrel 2 drives bearing plate 11 to move up and down, so as to deacclimatize the different paper for stacking thickness；
The top of framework 1 is symmetrically set with gear 4, and gear 4 rotates the peace for being connected and fixed on the inner chamber top plate of framework 1
41 are shelved, the bottom of gear 4 is connected with crank 42, and the other end of crank 42, which is connected with pressing roller holder 51, pressing roller holder 51, pacifies
Equipped with pressure roller 5, the line and horizontal line of the end face center of gear 4 and the end face center of pressure roller 5 are in 45 ° of angle, and such crank 42 exists
The trend pushed can be formed during outer swing；The upper lumen center of framework 1 is provided with to be meshed with two side gears 4
The two-sided rack 6, the top connection connecting pole 61 of the two-sided rack 6, connecting pole 61 is provided with roller after extending upward framework 1
611, back-moving spring 62 is connected between the inner chamber top plate of framework 1 and the top of the two-sided rack 6, back-moving spring 62 is set in connecting pole
61 periphery；The top of framework 1, which is fixed with door type frame 7, door type frame 7, is fixed with Cam rest 81, is installed on Cam rest 81
There is cam 8, cam 8 is provided with the motor (being not drawn into figure) of its rotation of driving, and cam 8 is in contact with roller 611, and cam 81 delays
Slow-speed is moved, and when its pair roller 611 exerts a force downwards, the two-sided rack 6 is moved down, while back-moving spring 62 is elongated, both sides
Gear 4 is meshed with the two-sided rack 6, wherein the gear 4 in left side is rotated counterclockwise, drives left crank 42 to laterally rotate, right
The gear 4 of side is rotated clockwise, and is rotated on the outside of the phase of crank 42 on the right side of drive, so that the pressure roller 5 of both sides turns laterally simultaneously
It is dynamic, pressure roller 5 is extruded from the center of paper to both sides paper, flatten effect usually ensure that, pullled in both sides
The fold on paper is evened up in the presence of power, while also it is avoided that paper offsets to one side, it is optional after once extruding is completed
The motor for closing cam 81 is selected, is resetted in the back stretch effect lower compression roller 5 of back-moving spring 62, naturally it is also possible to which selection is repeatedly squeezed
Press to ensure platen effect.
The present invention operation principle be：
In use, paper to be positioned over to the center of bearing plate 11, then according to the thickness that stacks of paper, selection, which allows, holds
Pressing plate 11 is moved up or moved down, what specific method was realized for the rotating of control dual-axle motor 3；The position adjustment of bearing plate 11
After good, control cam 81 is slowly rotated, and when its pair roller 611 exerts a force downwards, the two-sided rack 6 is moved down, while resetting bullet
Spring 62 is elongated, and the gear 4 of both sides is meshed with the two-sided rack 6, wherein the gear 4 in left side is rotated counterclockwise, drives left side bent
Handle 42 is laterally rotated, and the gear 4 on right side is rotated clockwise, and is rotated on the outside of the phase of crank 42 on the right side of drive, so that both sides
Pressure roller 5 is laterally rotated simultaneously, pressure roller 5 is extruded from the center of paper to both sides paper, ensure that pressing effect
Usually, pull and even up fold paper in the presence of power in both sides, while being also avoided that paper offsets to one side, once
It after extruding is completed, may be selected to close the motor of cam 81, resetted in the back stretch effect lower compression roller 5 of back-moving spring 62, when
Repeatedly extruding can also be so selected to ensure platen effect.
