Description

Offset press automatic control roller type draws the rule device

Technical field

The utility model relates to a kind of offset press and draws rule, and a kind of offset press automatic control roller type of more specifically saying so draws the rule device.

Background technology

Present most light-duty offset press, draw the paper that draws of rule to control about it, be that swing by a block length control panel moves up and down push rod to realize drawing the paper location, reason owing to raw material and processing technology, control panel is difficult to reach the specification requirement of design, cause when the size of printing sheets changes, along with drawing moving of rule, draw the rule and the handing-over time of preceding rule to change, thereby cause register trouble, this is one of its drawback, two of drawback is to draw the location-plate of rule narrow, the slight pressure of stage clip more greatly, the paper locating surface will bend, and also causes register trouble.

In rich formula 50 machines of Japan, about draw the paper that draws of rule to control by cylindrical cam, since this draw rule be fan-shaped board-like, promptly drawing paper is to swing by a fanning strip to realize, its weak point is: 1, increasing along with print speed printing speed, the inertia that the fanning strip swing is produced is also big more, causes register trouble; 2, along with the growth of service time, fanning strip will inevitably wear and tear, and also can cause register trouble; 3, to the requirement on machining accuracy height of associated components, assembling and adjustment are difficult.

Summary of the invention

The purpose of this utility model provide a kind of the size that changes printing sheets and improve under the situation of print speed printing speed chromatography accurately and the offset press automatic control roller type of being convenient to adjust draw the rule device.

In order to realize above-mentioned purpose, the offset press automatic control roller type that is provided draws the rule device, comprise and draw rule body and paper feeding frame, the bottom of paper feeding frame is connected with paper-pressing tongue, draw to be connected with on the end face of advising body and draw the rule cover plate, draw on the rule cover plate and be connected with location-plate, draw on the bottom surface of advising body and be connected with fixed block, draw in the endoporus of advising body and be fixed with driving gear, in the endoporus of driving gear, be fixed with the overhanging line shaft in two ends, its design feature is that an end of driving gear is connected with cylindrical cam, be fixed on the eccentric shaft vertical with the driven gear of driving gear engagement with line shaft, on driven gear, be connected with roller, cylindrical cam contacts with little bearing on being contained in swing arm one end, swing arm links together by a bindiny mechanism and paper feeding frame, and the paper pressure regulating mechanism is housed on the paper feeding frame, is connected to extension spring between the spindle nose of swing arm and eccentric shaft.

Above-mentioned bindiny mechanism comprises the stage clip that is contained in the swing arm endoporus and passes the adjustment screw that the paper feeding frame contacts with stage clip and be screwed in the locking nut of adjusting on the screw.

Above-mentioned paper pressure regulating mechanism comprises holding screw that is installed on the paper feeding frame and can contacts with the epimere of swing arm and the nut that is screwed on the holding screw.

This offset press automatic control roller type draws the rule device, cylindrical cam and driving gear be at the uniform velocity rotation under the drive of line shaft, the rotation control swing arm swing of cylindrical cam, when the little bearing in the swing arm is positioned at the height point of cylindrical cam, the paper feeding frame contacts with roller under the effect of extension spring, carry out rolling, the paper feeding frame is finished drawn the paper action, paper is moved on the location-plate; When the little bearing in the swing arm was positioned at the low spot of cylindrical cam, swing arm was with paper pressure regulating mechanism jack-up, and the paper feeding frame lifts, and finished the paper feeding action; Need different pressure for different paper, the adjustment of this pressure is finished by the paper pressure regulating mechanism; Driving gear drives driven gear and at the uniform velocity rotates, and the at the uniform velocity rotation of driven gear drives roller by eccentric shaft and at the uniform velocity rotates, because roller is packed on the eccentric shaft, just can adjusts roller by the off-centre of eccentric shaft and expose the height that draws the rule cover plate.

Offset press automatic control roller type provided by the utility model draws the rule device, its beneficial effect is: be to be controlled by cylindrical cam owing to drawing paper 1,, when the size of paper changes and improves print speed printing speed, the draw rule and the handing-over time of preceding rule that originally mixed up do not change substantially, do not influence the precision and the accuracy of chromatography; 2, owing to draw rule for roller type, and roller shaft is eccentric structure, therefore can regulate the height of roller, improved efficiency of assembling, highly still can continue to use by regulating it behind rolling wheel wear, needn't change; 3, will draw the length lengthening of the location-plate of rule, the quantity of its lengthening is not less than twice, and after paper was moved location-plate to, little distortion that its paper produced weakened greatly, had shortened the adjustment time of chromatography, had improved chromatography precision.
