Sensor 6.6a is provided with one on flank of cam for triggering the convex block 6.6b of the proximity sensor, and the proximity sensor is solid
It is scheduled in the mounting base 6.1.When the convex block turns at proximity sensor, proximity sensor can be triggered, and show grid
Panel resets in place, and the trigger signal of generation is sent to reference of the control system of printing machine as printing machine control paper feeding process
Data.
In order to further decrease the occupied space of entire front edge paper feed platform, its compactedness is further increased, described second
The bottom of front edge paper feed platform is arranged in servo motor 7 inwardly, and second servo motor and mounting base 6.1 are connected, corresponding side
The U-shaped opening 1.1a passed through for the second servo motor is offered on plate 1.1, as shown in Figure 5.
Further, see that Fig. 6, the grate panel 3 include grills 3.1 and the flase floor being fixed at the top of grills
3.2, the forward and backward edge of grills is the pressure contact portion 3.1a that height is lower than flase floor, is provided with above pressure contact portion solid with rack 1
Pressing plate 1.2 even, is connected with several compressed spring 3.1b between pressing plate and pressure contact portion.On the one hand, compressed spring can be to grid face
Plate is buffered, and the vibration generated when grate panel rises is reduced, and on the other hand, compressed spring generates downwards grate panel
Pretightning force, can guarantee pile transfers grate panel can reliable reset, also ensure rocker arm and cam reliable contacts.
Herein, the flase floor 3.2 of each 3.1 settable monolith in top of grills, may also set up the lesser grid of muti-piece
Plate 3.2.
