Main design objective of the present utility model, be to solve the paper feeding problem that above-mentioned duplicating machine exists, design a kind of can be preferably only seize a piece of paper at every turn get the paper paper advance mechanism, also design only needs to clad Waxpaper with a cylinder simultaneously, and setting is coated with device for ink in this cylinder, overall structure more is becoming tight gathers.

The utility model aspiration paper feeding mimeograph, its primary structure is by the cylinder that can clad Waxpaper, be coated with device for ink, regularly get the paper paper advance mechanism, compositions such as defeated tight roller of letterweight and transmission mechanism, the main distinction feature of it and duplicating machine is: at the front end of getting the paper paper advance mechanism heating is housed, is used for heating the surperficial end of waiting to print paper, a piece of paper end at first is heated curl and with the paper natural separation of lower floor; By the pump type aspirator, utilize principle of negative pressure to draw a piece of paper; Drive paper pushing board by transmission device again, a piece of paper that is attached under the paper pushing board with suction is sent to the defeated tight roller of letterweight.

Accompanying drawing 1 is the structural representation of aspiration paper feeding mimeograph.

Further describe below in conjunction with 1 pair of structural principle of the present utility model of accompanying drawing.

The transmission mechanism of aspiration paper feeding mimeograph, by the crank 2 that links with mimeograph cylinder 1, connecting rod 3, tooth bar 4,6, gear 5 and form with the push rod 12 that tooth bar 4 connects firmly.When crank 2 along K when rotating, mimeograph cylinder 1 also simultaneously K to widely different commentaries on classics, pin joint drivening rod 3 by crank 2 ends, drag tooth bar 4 rectilinear motion left, make simultaneously gear 5 on it by T to rotation, gear 5 promotes upwards rectilinear motion of tooth bar 6 again, in brief, the pin joint 14 of tooth bar 6 one ends of this moment has been realized upwards rectilinear motion, and the apical grafting point 13 of push rod 12 1 ends has been realized rectilinear motion left simultaneously; Otherwise, when crank 2 goes to another appropriate location,, make pin joint 14 realize downward rectilinear motion by above-mentioned drive connection, apical grafting point 13 is realized rectilinear motion to the right simultaneously.Mimeograph get the paper paper advance mechanism,, the heating 8(example electric heating iron core that bellows 7 left ends are outer mainly by folding bellows 7) and paper pushing board 11 compositions.The top board of bellows 7 and pin joint 14 are hinged, can move up and down; The base plate and the frame of bellows 7 connect firmly, and its left part is provided with 2-4 row aperture 10, and these apertures 10 are unique passages of outside air turnover bellows 7 inside.The left side of paper pushing board 11 is provided with 5-15 row aperture 15, and the base plate that paper pushing board 11 can be close to bellows 7 horizontally slips, and in the sliding process of paper pushing board 11, has aperture 10 to communicate with aperture 15 all the time.Be lined with the mica sheet of partiting thermal insulation around the heating 8, when heating 8 adstante febres, being in the paper pushing board 11 following left parts of printing paper of waiting is heated, because the expanded by heating of paper fiber makes the left end of a piece of paper on the face at first curling, simultaneously with lower floor's paper natural separation, if upwards spur the former top board that be the bellows 7 of compressive state by pin joint 14 this moment, make bellows 7 inside be in negative pressure state, under external atmospheric pressure, the left end portion of a piece of paper is attracted on the paper pushing board 11.When pin joint 14 continues to move upward, apical grafting point 13 is also simultaneously to left movement, apical grafting point 13 contact paper pushing boards 11 promptly take place after a while, then promote paper pushing board 11 left, make a piece of paper that always is adsorbed on the paper pushing board 11 also simultaneously to left movement, and then the platen angle card 25 that makes a piece of paper break away from control paper height position fully, until the left end of this paper is sent to the tangent slit of cylinder 1 and roller pressing 16 always.Then pin joint 14 begins to move downward with apical grafting point 13 and begins to move right, because pressing down of bellows 7 top boards, make bellows 7 inside be in barotropic state, so a piece of paper is forced to break away from paper pushing board 11, paper pushing board 11 returns back to the diagram reset condition because of spring 17 pulling force simultaneously, the left end of later a piece of paper draws in this tangent gap by the relative rolling of cylinder 1 and roller 16, on one side mimeograph export outside the machine on one side.Below getting of each paper inhale that course of conveying can the rest may be inferred.
