Specific embodiment
With reference to the accompanying drawing, the utility model is described in further detail for embodiment.
As shown in Figure 1, existing paper feed mechanism of printer, generally comprises paper feed motor 1, intake roller 2, paper feeding mechanism, into
Paper motor 1 by transmission mechanism drive intake roller 2, intake roller 2 again by transmission mechanism go driving paper feeding mechanism realization pickup (into
Paper), typewriting paper feed, the relative motions such as paper delivery.
As shown in Figure 2,3, the paper blocking mechanism in paper feed mechanism of printer, including transmission component 4, paper blocking mechanism 5.
As shown in Figure 4,5, transmission component 4 includes gearing frame 10, pickup transmission front gear 11, fupport arm spring 13, fupport arm
14, pickup is driven middle gear 12, fupport arm gear 15.
Gearing frame 10 is fixed on 7 chassis of framework, arcuate socket 101 is arranged, for guiding fupport arm axis 142 and rotating for it
Movement setting beginning and end, is arranged axis 102,103.
Pickup transmission middle gear 12 is removably secured on gearing frame 10 by axis 103, and is driven nipper with pickup
11 engagement of wheel.
Fupport arm axis 142 is arranged in 14 side of fupport arm, and fupport arm gear 15 is connected in fupport arm 14 by fupport arm axis 142, and arm
Ask 142 top of axis in the arc groove 101 of gearing frame 10, therefore the movement of fupport arm 14 and fupport arm gear 15 is by arc groove
101 limitation and guidance.
Fupport arm gear 15 is mainly used for paper-rubbing mechanism, because unrelated with the technical solution of the present embodiment, therefore no longer opens up herein
Open narration.
13 one end of fupport arm spring is limited by pickup transmission middle gear 12, and the other end is limited by fupport arm 14, and fupport arm spring 13 is right
Pickup is driven middle gear 12 and applies axial force F, and pickup is driven middle gear 12 when rotated, can drive during fupport arm 14 is driven with pickup
Gear centre and move that (radial frictional force that middle gears 12 and fupport arm 14 are driven by i.e. 13 pairs of fupport arm spring of axial force F is real
It is existing), rotate fupport arm 14 along arcuate socket 101 on gearing frame 10.
It is another transmission component of another embodiment as shown in Fig. 6,7,8 comprising: pickup is driven front gear 11, passes
Dynamic frame 10, fupport arm spring 13, fupport arm 14, pickup transmission middle gear 12, fupport arm gear 15, felt 16 and fupport arm disk 17.
Increase felt 16 and fupport arm disk 17 in the present embodiment, felt 16 is attached on pickup transmission middle gear 12, leads to
Cross the relative friction forces changed between pickup transmission middle gear 12 and fupport arm 14 using felt 16.
Radial slot 143 is set in fupport arm 14, radial block 171 is set on fupport arm disk 17, fupport arm disk 17 and fupport arm 14 it
Between radial slot 143 and radial block 171 link together, form radial limit, therefore be unable to relative rotation.
13 one end of fupport arm spring and fupport arm disk 17 limit, and the other end 131 and fupport arm 14 limit (13 other end of fupport arm spring
In 131 insertion radial slots 143, therefore fupport arm spring 13 and fupport arm 14 are unable to relative rotation), such fupport arm spring 13 and fupport arm
14, fupport arm disk 17 constitutes an entirety.
In the present embodiment, in the entirety and felt 16 and pickup transmission that fupport arm spring 13, fupport arm 14, fupport arm disk 17 are constituted
The coefficient of friction between entirety that gear 12 is constituted is bigger than embodiment 1, therefore optimizes the technical solution of embodiment 1.
As shown in Figure 2,3, paper blocking mechanism 5 includes blend stop arm 19, blend stop 20, blend stop hinge 18, and interval is arranged on blend stop 20
Baffle 201,20 one end of blend stop, 203 axis is connected in framework 7, and the other end 202 is fixed on the side 192 of blend stop arm 19, blend stop
Another side axle 191 of arm 19 be fixed on one end 181 of blend stop hinge 18 (19 side 193 of shelves arm be circular shaft face, with framework 7 on
Hole cooperation), the other end 182 of blend stop hinge 18 and fupport arm 14 are that hole axle cooperates, and are connected to one by the axis 141 in fupport arm 14
It rises, therefore, blend stop hinge 18 and fupport arm 14 can carry out relative rotary motion, and blend stop 20 can also be with respect to blend stop hinge 18 and fupport arm 14
It is rotated.
Pickup transmission front gear 11 is removably secured on gearing frame 10 by axis 102, and with tooth in pickup transmission
12 engagement of wheel.
As shown in Figures 9 and 10, it when paper feed motor 1 inverts, is driven by 2 transmission mechanism of formfeed stick, paper blocking mechanism rotates forward, gear
Blend stop 20 in mechanism of paper rotates forward, and the baffle 203 on blend stop 20 stops paper road, hinders remaining sheet movement.
When rotating forward such as Figure 11,12 paper feed motors 1, paper blocking mechanism reversion drives fupport arm 14 along arc on gearing frame 10
Hole 101 is moved upward, while driving blend stop 20 to swing by the blend stop hinge 18 of driving 14 other side of fupport arm connection, is flapped toward another
Side makes the baffle 203 on blend stop 20 not interfere paper road, so as to smooth pickup.
