Abstract
The utility model provides an automatic paper feeding device, which comprises a pressure wheel component and a sand shaft component, wherein, the pressure wheel component comprises a guiding rail, a base, a pressure arm, a pressure wheel, an adjusting component and a square shaft component; the sand shaft component comprises a transmission shaft component, a main beam and a paper delivery roller; clamping grooves are respectively formed on both sides of the lower surface of the guiding rail; and the base is installed on the guiding rail through the clamping grooves formed on the both sides of the lower surface of the guiding rail. The automatic paper feeding device has the advantages of simple structure, stable working performance, firm installation of the base, accurate adjustment of an adjusting base and high printing precision.
Description
Technical field
The utility model relates to a kind of automatic document feeder.
Background technology
Automatic document feeder is the principal organ of printing machinery, and it comprises pinch roller assembly and husky shaft assembly, and wherein pinch roller assembly comprises pedestal, guide rail, pressure arm, pinch roller, and pedestal is installed on the draw-in groove of guide rail lower end.The feed roller of the husky shaft assembly of motor-driven rotates, and pinch roller is pressed in printing paper on the feed roller, makes pinch roller rotate together by friction, so with printing paper to front transfer.At present, its lower end of the guide rail of automatic document feeder pinch roller assembly has only a draw-in groove, and pedestal is mounted thereto, and poor stability causes the pressure of each pinch roller to differ bigger; When pedestal rocks greatly, even can exceed the adjustable range that is installed in pressure arm afterbody adjustment seat, cause the regulating effect of adjustment seat undesirable, influence printing precision.
The utility model content
For addressing the above problem, the utility model provides a kind of automatic document feeder, and this apparatus structure is simple, stable work in work, and pedestal is installed firmly, the printing precision height.
The technical scheme that the utility model is adopted for achieving the above object is:
Automatic document feeder comprises pinch roller assembly, husky shaft assembly, and described pinch roller assembly comprises guide rail, pedestal, pressure arm, pinch roller, adjusting part, square shaft assembly; Described husky shaft assembly comprises transmission shaft component, girder, feed roller, and described guide rail lower surface both sides have draw-in groove respectively, and described pedestal is installed on the guide rail by two side bayonet slots.
The pressure arm of this device is installed on the pedestal by connector, and is that the strong point can be swung with this connector; Pinch roller is installed in the pressure arm front end; Adjusting part is installed in the pressure arm afterbody, and adjusting part comprises spring, adjustment seat, adjustment screw, is connected by spring between adjustment seat and the pedestal; The square shaft assembly is installed on the pedestal, and the square shaft assembly comprises square shaft, cam, and described cam is fixed on the square shaft outer surface, according to lever principle, is the strong point with the connector, pressing down and lifting by cam and spring control pressure arm; Feed roller is installed on the girder by transmission shaft component, and transmission shaft component comprises power transmission shaft, bearing block, and feed roller is fixed on the power transmission shaft outer surface.
The utility model has increased draw-in groove on guide rail, make the very firm of pedestal installation, the performance of adjustment seat significantly rises, the pressure of each pinch roller differs very little, adjustable range much smaller than adjustment seat, by the fine setting of adjustment seat, make the pressure unanimity on each pinch roller, thereby guaranteed very high printing precision.
Description of drawings
Come the utility model is described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-guide rail, 1-1-draw-in groove, 2-pedestal, 3-pressure arm, 4-pinch roller, 5-spring, the 6-adjustment seat, 7-adjustment screw, 8-square shaft, 9-cam, 9-1-cam minimum point, 9-2-cam peak, the 10-girder, 11-feed roller, 12-power transmission shaft, 13-bearing block, 14-bearing pin.
The specific embodiment
As shown in Figure 1, automatic document feeder comprises pinch roller assembly, husky shaft assembly, and described pinch roller assembly comprises guide rail 1, pedestal 2, pressure arm 3, pinch roller 4, adjusting part, square shaft assembly.Adjusting part comprises spring 5, adjustment seat 6, adjustment screw 7; The square shaft assembly comprises square shaft 8, cam 9.
Described husky shaft assembly comprises transmission shaft component, girder 10, feed roller 11; Transmission shaft component comprises power transmission shaft 12, bearing block 13.
This device guide rail 1 lower surface both sides have draw-in groove 1-1 respectively, and pedestal 2 is installed on the guide rail 1 by two side bayonet slot 1-1.
The bearing block 13 of transmission shaft component is fixedlyed connected with girder 10, and power transmission shaft 12 passes bearing block 13 by bearing, and feed roller 11 is fixed on power transmission shaft 12 outer surfaces.
During work: rotate by motor-driven power transmission shaft 12, promptly driving feed roller 11 rotates, rotating square shaft 8 by handle makes the 9-1 of minimum point place of the cam 9 on it forward lower end and pressure arm 3 opposite positions to, be the strong point with bearing pin 14 this moment, and pressure arm 3 is owing to the elastic force effect of spring 5, and afterbody lifts, front end presses down, be that pinch roller 4 is pressed in printing paper on the feed roller 11, make pinch roller 4 rotate together by friction, so with printing paper to front transfer; If stop to print, then rotate square shaft 8 and make the 9-2 of peak place of cam 9 forward to contact, the afterbody of pressure arm 3 is depressed that front end lifts with pressure arm 3, promptly pinch roller 4 breaks away from and the contacting of printing paper, and turns off motor, stops printing.
Two draw-in groove 1-1 on the guide rail 1 have guaranteed that pedestal 2 is firmly stable, thereby make the pressure size on each pressure arm 3 of printing machine basic identical, small deviation can be regulated by the adjustment seat 6 of pressure arm 3 afterbodys, promptly when other pinch rollers of the pressure ratio of certain pinch roller 44 were bigger than normal or less than normal, turn adjustment screw 7 can be adjusted the pressure of pinch roller 4.
The utility model is simple in structure, stable work in work, and pedestal is installed firmly, and adjustment seat is regulated accurately, the printing precision height.
