Abstract
The utility model relates to a one-piece paper feeding mechanism for small-size printing machine, which mainly comprises a wheel for feeding paper, a wheel for dividing paper, a belt wheel, a belt, a friction plate, etc. The paper feeding movement of the wheel for feeding paper and the paper dividing movement of the wheel for dividing paper realize the continuous paper feeding and paper dividing, which effectively realizes the one-piece paper feeding of the small-size printing machine. The utility model has the advantages of simple structure, low cost, small size and high reliability, and because of the one-piece paper feeding, the paper can be saved.
Description
The utility model relates to a kind of individual paper-feeding mechanism that is used for small-print machinery (as copygraph, offset printing press, join this machine, folding machine, duplicator etc.).
At present, in the use of small-print machinery, because paper is coarse or band Static electricity, two opening even many paper supply phenomenons usually occur, this has not only caused the waste of paper, has also influenced work efficiency simultaneously greatly.For this problem, the public clear 51-24924 of Japanese Patent Laid has proposed a solution: the cushion block that certain material is made places pile front end paper-sheets rolling wheel below, the friction coefficient between cushion block and the paper greater than the friction coefficient between the paper less than the friction coefficient between paper and the paper-sheets rolling wheel.Like this, when two Zhang Shike occurring following a piece of paper is separated and is detained, and when having only a piece of paper, paper can be sent smoothly.But cushion block material surface character is difficult to long-term stability in above-mentioned scope in actual use, and two, many paper supply phenomenons still are difficult to avoid.
The utility model aims to provide a kind of mechanism that can guarantee individual paper supply, and it has solved the problem of two of small-print machineries or many paper supplies.
The utility model mainly is made up of two identical paper supplies, one separation wheels, paper-sheets rolling wheel axle (11), separation wheel shaft (12), belt pulley (13), (14) and belt (15) and framework (16).Two paper supplies, one separation wheels are symmetrically distributed in the both sides of axle (11), (12); Each paper supply one separation wheels all includes paper-sheets rolling wheel (1), separation wheel (2), axle sleeve (3), (4), axle sleeve holding screw (5), (6), nut (7), (8), rubber cradle (9), friction lining (10) and free-wheel clutch (17).Axle sleeve (3) by screw (5) location is installed on the paper-sheets rolling wheel axle, and paper-sheets rolling wheel (1) matches with axle sleeve (3), therebetween and free-wheel clutch is housed; Axle sleeve (4) by screw (6) location is installed on the separation wheel shaft, separation wheel (2), nut (7), (8), rubber cradle (9), friction lining (10) all matches with axle sleeve (4), by nut (7), (8) and a contacts side surfaces of the sheet that rubs (10) that compresses vertically of packing ring (9) and separation wheel, axle (11), (12) be positioned on the framework (16), distance between them equals paper-sheets rolling wheel and separation wheel outer rim radius sum, individual paper-feeding mechanism of Gou Chenging thus, simple in structure, volume is little, cost is low, it is applicable to that various small-print machineries carry out individual paper supply to various paper, functional reliability is strong, easy and simple to handle, both save paper, improved work efficiency again, had better economic efficient.
Below with reference to accompanying drawing in detail embodiment of the present utility model is described in detail:
Fig. 1: separation schematic diagram of the present utility model;
Fig. 2: paper supply schematic diagram of the present utility model;
Fig. 3: main cutaway view of the present utility model;
Fig. 4: the lateral plan of figure (3).
The utility model is to realize like this, belt among the figure (15) drive pulley (13), (14) under the effect of extraneous transmission power source rotate counterclockwise, and simultaneously driving torque is passed to axle sleeve (3) and (4) that connect with it respectively by paper-sheets rolling wheel axle (11) and separation wheel shaft (12), axle sleeve (3), (4) transmission, paper-sheets rolling wheel (1) rotates counterclockwise.Before the work, paper-sheets rolling wheel (1) pile front end paper is contacted with suitable pressure with separation wheel (2), again each paper supply one separation wheels is adjusted, make between separation wheel (2) and the friction film (10) friction force less than separation take turns between (2) and the paper friction force and greater than the friction force between paper and the paper.During work, paper-sheets rolling wheel (1) is rubbed the paper above the pile with the hands by transmission, and pushes to separation wheel (2) direction, up to entering between wheel (1), (2).When importing for sheet-fed between paper-sheets rolling wheel and separation wheel, because the friction force between separation wheel (2) and friction lining (10) is less than the friction force between separation wheel (2) and paper, separation wheel (2) will be driven by the sheet-fed by the paper-sheets rolling wheel rubbing to go up at axle sleeve (4) and slide and clockwise rotate, and this moment, it was sent paper together with paper-sheets rolling wheel; As two paper near or when entering contact zone between taking turns of paper-sheets rolling wheel and separation, because friction force between separation wheel and friction lining (10) and the friction force between separation wheel and paper are all greater than the friction force between paper and paper, separation this moment wheel will stop to clockwise rotate or rotating counterclockwise under the friction force effect of friction lining (10), satisfy two following a piece of papers of opening in the paper are pushed to the pile direction, and it is sent contact zone between two-wheeled, the separation wheel then stops to rotate counterclockwise, thereby has realized the sheet-fed input.
The sheet-fed afterbody that is transfused to leaves before wheel (1) and the contact zone of wheel between (2), its front end will partly be bitten by machinery operation and to front haulage, this moment, propulsion source stopped operating, wheel (1) stops operating, wheel (1) free-wheel clutch interaxle with it thrown off automatically, and wheel (1) is driven and rotates by paper.Leave the contact wire of wheel (1) and pile when the paper tail after, below a piece of paper will be by wheel (1) rubbing forward, the place, contact zone stops between wheel (1) and wheel (2) until arriving, and waits for that next time propulsion source starts and provides next time that paper feeding moves.Guaranteed that thus every paper end all is in wheel (1) and wheel (2) place, contact zone when paper feeding action beginning, reached the conformability of paper feeding position.
For guaranteeing to carry out effectively paper supply and separation, the outer rim of paper-sheets rolling wheel and separation wheel is made by elastomeric material.
