Block 4, the connection paper storehouses 1 and page turning channel are provided on the upper paper block 4 leads paper convex ribs 41, can by leading paper convex ribs 41
The case where printing paper is smoothly oriented to the page turning channel of page turner mechanism 3, avoids paper jam appearance.
Referring to Fig. 3~Fig. 5, in the present embodiment, it is preferred that the paper convex ribs 41 of leading are obliquely installed for two, the paper
The rear end in storehouse 1 be provided with the oblique conducting bar 12 leading paper convex ribs 41 and matching, two are led that top is provided between paper convex ribs 41 is flat
Damping mechanism is flat to push up the end of printing paper in paper storehouses 1.The flat damping mechanism in top includes stop support 61, the first sliding block
62, the second sliding block 63 and block swing rod 64, the stop support 61 are provided with sliding slot 611, first sliding block 62 and second
Sliding block 63 is slidably connected on the stop support 61 and can move along the sliding slot 611, and second sliding block 63 is provided with
The guide pad 631 in the sliding slot 611 is protruded into, the sliding slot 611 is filled with lubricating grease；First sliding block 62, which is provided with, to be used for
The pushing part 621 for contacting paper storehouses is provided with the first spring 65 described in holding between first sliding block 62 and stop support 61
Pushing part 621 is located at outside stop support 61, is connected between first sliding block 62 and the second sliding block 63 by second spring 66, institute
The lower end for stating block swing rod 64 is articulated with the stop support 61, and second sliding block 63 is provided with and the block swing rod 64
Corresponding linkage portion 632 is set, the linkage portion 632 is provided with end to end horizontal concrete chute and the vertical chute, the block pendulum
Bar 64 is provided with the guide post 641 being caught in the horizontal concrete chute and the vertical chute, and before being packed into paper storehouses 1, the block swing rod 64 is protected
Hold vertical state.It is mobile that 1 push-on process of paper storehouses will push the first sliding block 62, and the first sliding block 62 pushes the by second spring 66
Two sliding blocks 63, the forced compression of second spring 66 is a process, therefore the movement of the second sliding block 63 always lags behind first and slides
Block increases resistance to sliding in addition being filled with enough lubricating grease in sliding slot 611, further decreases the movement of the second sliding block 63
Speed, therefore the second sliding block 63 is slowly slided along sliding slot 611.Second sliding block 63 moves into two processes, process first is that
The state of Fig. 4 is transformed by the state of Fig. 3, the level that the guide post 641 of block swing rod 64 is in linkage portion 32 in the process is slided
In slot, therefore the movement of sliding block 62 is not applied on block swing rod 64, i.e., block swing rod 64 is in a vertical state always；Process
Second is that going to the state of Fig. 5 by the state of Fig. 4, guide post 641 moves in the vertical chute of linkage portion 632 in the process,
Under the action of the vertical chute, linkage portion 632 generates a rotating torque to block swing rod 64 and block swing rod 64 is tilted backwards,
Until the second sliding block 63 slide to the end as shown in figure 5, the side of final block swing rod 64 with lead paper convex ribs 41, oblique conducting bar 12 inclines
Rake angle is consistent, therefore analyzes from whole process, and the swing of block swing rod 64 lags behind the movement of the second sliding block 63, and second is sliding
The movement of block 63 lags behind the movement of the first sliding block 62 and paper storehouses 1, and the swing of block swing rod 64 significantly lags behind the shifting of paper storehouses 1
Dynamic, effect is when paper storehouses 1 promote backstop swing rod 64 not to be flapped toward immediately below, and the lag of block swing rod 64 is swung paper storehouses
The end top of printing paper in 1 is flat, guarantees the paper feed device of printing paper and in the right direction, avoids print pattern lateral deviation, favorably
In raising print quality.
In the present embodiment, it is preferred that the both ends of the second spring 66 are separately connected the pushing part 621 and guide pad
631, the second spring 66 and the first spring 65 are arranged in the sliding slot 611.It can be into using the lubricating grease in sliding slot 11
The compression process of one step slow second spring 66 and the first spring 65 reduces the movement speed of the second sliding block 33.
The above, the only better embodiment of the utility model, but the utility model is not limited to above-mentioned reality
Example is applied, as long as its technical effect for reaching the utility model with any same or similar means, should all fall into the utility model
Within protection scope.
