Description

The pneumatic side gauge device of printing machine

Technical field:

Before the utility model related to press printing, paper must by side gauge device to its pneumatic side gauge device of a kind of printing machine that carries out vertical and horizontal both direction location, be specially adapted to use on the high-speed press.

Background technology:

Existing side mark function is to realize paper is carried out located lateral, between guarantee printed sheet and printed sheet, look and the look chromatography accurate, existing side mark paper pulling roller is done the integral cycle rotating motion, moves and is all realized by gear drive.Spur gear is wherein arranged, bevel gear is arranged again.During working gear, because the vibration that processing and rigging error cause is directly passed to paper pulling roller.The side mark power transmission shaft since the restriction of machine space structure often diameter dimension is very little, length is very long, draw ratio is generally 90 to 115, the rigidity after the assembling is very poor, roller can produce " beating " during work.The paper location is unstable.Paper pulling roller and travelling gear one are made integral cycle rotating during work, can't effectively adjust the frictional force of roller and paper when the printing sheets specifications vary.Only realize by the pressure that strengthens mechanism of paper holding, can aggravate again the unstability of side mark work.Another side mark be by the side mark tape roller by actuated by cams, only make certain angle and swing.Avoided gear drive error.Tape roller is no longer made continuous integral cycle rotating as traditional side mark tape roller, but changes the swing of making certain angle by the curved surface of cam.The side mark tape roller can be adjusted according to paper from the frictional force of paper and use different working faces.According to the difference of machine printing sheets specification, the side mark tape roller has larger difference to the frictional force of paper, can make different surfaces with corresponding material at the different parts of tape roller this moment and adapt to requirement to paper frictional force.

Summary of the invention:

Task of the present utility model is that proposition is a kind of according to the different air-flow sizes that change of paper sheet thickness, realizes the pneumatic side gauge device of a kind of printing machine that accurately draws paper to locate.

Task of the present utility model is finished like this, the pneumatic side gauge device of printing machine, it comprises that roller is by actuated by cams, it is characterized in that: side mark is assemblied in the top of paper platform, be equipped with edge cam on the line shaft, roller is contained on the fork, fork is fixed on the paper platform by the bearing pin, being equipped with folded spring on the fork fixes by pin and connecting rod, the other end of connecting rod is fixed by pin and supporting plate, is connected with on the supporting plate to draw cardboard, is fixed with the extension spring nail on the described paper platform, extension spring one end hangs over extension spring and nails on, the other end hangs on the connecting rod, is equipped with a pair roller on the described supporting plate, and roller rolls in the guide rail of correspondence, guide rail is fixed on the frame, is equipped with little air-breathing the wheel and large air-breathing interface on the described paper platform.

The utlity model has following effect: the side mark structure can be guaranteed the printing sheets location at a high speed, and is steadily, accurately, reliable.Side mark draws the high-frequency of cardboard to swing to be by edge cam, fork, connecting rod transferring power, extension spring to be arranged so that roller is pressed on the edge cam all the time.Connecting rod has elimination gap, locking functions in the structure.Swung rolling guide guiding of supporting plate, rolling guide frictional resistance is little, draws the cardboard autokinesis high.Side mark draws paper power size to be determined by the air-flow size.According to paper sheet thickness and little air-breathing the wheel or large air-breathing interface of material different choice.Stable and the size of air-flow is by accurate Air Valve Control.The adjustment mode is simple, and is easy to operate.Avoid traditional replacing spring, increased the drawback of drawing paper frictional force by the elastic force that increases stage clip.

Drawing explanation: 1, draw cardboard, 2, side mark, 3, fork, 4, paper platform, 5, edge cam, 6, extension spring nail, 7, extension spring, 8, supporting plate, 9, little air-breathing the wheel, 10, pin, 11, connecting rod, 12, folded spring, 10-13, pin, 14 rollers, 15, the bearing pin, 16, guide rail, 17, roller, 18, large air-breathing interface, 19, line shaft.

The specific embodiment:

Describe embodiment in detail in conjunction with above accompanying drawing, side mark 2 is assemblied in the top of paper platform 4, be equipped with edge cam 5 on the line shaft, roller 14 is contained on the fork 3, the edge cam driving rolls axially moves, fork is fixed on the paper platform by bearing pin 15, it is fixing by pin 10-13 and connecting rod 11 to be equipped with folded spring 12 on the fork, purpose is in order to eliminate the gap, and loosening when preventing high frequency motion, the other end of connecting rod is fixed by pin 10 and supporting plate, be connected with on the supporting plate 8 and draw cardboard 1, roller shaft is to moving belt movable pendulum bar 3, and connecting rod and supporting plate 8 and drive draw cardboard 1 to swing, and realize laterally drawing paper.Be fixed with extension spring nail 6 on the described paper platform 4, extension spring one end hangs over extension spring and nails on, and the other end hangs on the connecting rod 11, and the pulling force of extension spring is pressed on the edge cam 5 roller 14 all the time, thereby so that link to each other with supporting plate 8 to draw cardboard 1 to swing uniform and stable, avoid beating.Be equipped with a pair roller 17 on the described supporting plate 8, roller 17 is in the guide rail 16 interior rollings of correspondence, and guide rail is fixed on the frame, guarantee layback precision, motion steadily, friction is little.When printing paper sheet thickness, material is different, the layback air-flow is also different, be equipped with on the described paper platform 8 and littlely air-breathingly take turns 9 and large air-breathing interface 18, when printing thin paper, only need to connect and littlely air-breathingly take turns 9, connect large air-breathing interface 18 during paper that printing is thick and make on the supporting plate large-area pore air-flow unobstructed, suction strengthens.During the side mark off working state, side mark 2 has other special mechanism to lift above paper platform 4, and is no longer spacing to the paper side, stop suction wheel 9 and large air-breathing interface 18 air suction functions, and the rule side quits work.
