Abstract
The utility model discloses a rubber roll landing gear device for an offset printing machine. The rubber roll landing gear device comprises a plate cylinder, wherein the shaft head of the plate cylinder (7) penetrates through a wallboard hole, and is sleeved with a cam (16); the cam (16) is propped against the wallboard, and is located through pressure plates (20) which are fixed onto the end surface of the plate cylinder shaft head; an air cylinder fulcrum (9) is mounted at the tail part of an air cylinder (18); two ends of a swing rod (2-1) are hinged to the air cylinder and a connecting rod (14-1) respectively; two ends of the connecting rod is hinged to the swing rod and the cam (16) respectively; the roller (19), the plate roll shifting rolls (3) and the connecting rod (14) are all mounted in four holes in the swing rod (2) respectively and correspondingly; the pressure plates (20) are uniformly distributed on the end surface of the shaft head of the plate cylinder (7). The rubber roll landing gear device has the effects of improving presswork quality, preventing printing ink from entering the plate, which causes the presswork to have too much ink, and the next printing is not facilitated.
Description
Technical field:
The utility model relates to a kind of rubber roll landing gear, is specially adapted to offset press and uses when printing.
Background technology:
Offset press need to contact with plate cylinder with the version of leaning on of printing ink when printing, in order to printing ink is passed on forme, thereby printing ink is passed on paper and realizes printing functionality, when not printing, need to break away from copy roller and the plate cylinder of printing ink, avoid printing ink to pass on forme, make space of a whole page mass colour weight, be unfavorable for subsequent printings, the realization of This move is that the rubber roll landing gear by offset press completes, existing rubber roll landing gear is (see figure 1), plate cylinder 7 spindle noses are through on wallboard, undercarriage 8 lean against on wallboard and empty frame on plate cylinder 7 spindle noses, respectively there is up and down screw 10 to be fixed on wallboard, undercarriage 8 can move up and down, jacking block 5 is fixed on wallboard and can rotates around little axle 6 by little axle 6, screw 4 is screwed on jacking block 5, spring base 13 is screwed on connecting rod 14, through being fixed on the fulcrum 12 on wallboard, can stretch back and forth thereon, spring 11 is through on spring base 13, be arranged between connecting rod 14 and fulcrum 12, adjusting nut 15 is housed on spring base 13.
When machine is converted to not printing state from printing state, undercarriage 8 withstands its plane, bottom surface through other parts, make it by the wallboard segment distance that moves up, thereby drive jacking block 5 and screw 4, make jacking block 5 and screw 4 motions promote fork 2 around roll shifting 1 central rotation, drive is contained in copy roller 3 on fork and promotes together to break away from plate cylinder 7, and spring 11 is compressed, and the gap between each part makes progress.When machine, when never printing state is converted to printing state, the movement relation between each part is contrary to the above, and the gap between each part makes progress.This mechanism, due at printing state and printing state not, the gap between each part is contrary, this makes this mechanism have unstability in transition process.Copy roller 3 leans against on plate cylinder 7 needs certain pressure, because plate cylinder 7 was upwards had time and kept off in week, when copy roller 3 leans against on plate cylinder 7, when plate cylinder forwards entity in the copy roller position to from neutral, copy roller 3 is knocked and lifts, and then drops on plate cylinder 7, the excessive black thick stick of China ink amount will occur in position, forme front like this, thereby make on printing to occur black thick stick, affect the quality of printing.
Summary of the invention:
Task of the present utility model is to solve because clearance mechanism is unstable, the problem of the excessive black thick stick of China ink amount occurs in mouth position, forme front.
Task of the present utility model completes like this, rubber roll landing gear on a kind of offset press, it comprises plate cylinder, it is characterized in that: plate cylinder (7) spindle nose is through in the wallboard hole, cam (16) is enclosed within on the spindle nose of plate cylinder and leans against on wallboard, by pressing plate (20) location be fixed on the plate cylinder shaft end surface, cylinder (18) afterbody is equipped with cylinder fulcrum (9), fork (2-1) two ends are hinged on respectively (14-1) on cylinder and connecting rod, the connecting rod two ends are hinged on respectively on fork and cam (16), roller (19), copy roller roll shifting (3) and connecting rod (14) correspondence respectively are arranged in four holes of fork (2).Described pressing plate (20) is by a minute individual end face that is evenly distributed on plate cylinder (7) spindle nose.
The utlity model has following effect is to improve print quality, avoids printing ink to pass on forme, makes space of a whole page mass colour weight, the rubber roll landing gear on a kind of offset press of unfavorable subsequent printings.
The accompanying drawing explanation:
Fig. 1 is the prior art structural representation; Fig. 2 is structural representation of the present utility model.
Prior art drawing explanation: 1, roll shifting, 2, fork, 3, copy roller, 4, screw, 5, jacking block, 6, little axle, 7, plate cylinder, 8, undercarriage, 10, screw, 11, spring, 12, fulcrum, 13, spring base, 14, connecting rod, 15, adjusting nut.
Drawing of the present utility model explanation: 1, roll shifting, 2, fork, 3, copy roller, 7, plate cylinder, 11, spring, 12, fulcrum, 13, spring base, 14, connecting rod, 15, adjusting nut, 9, cylinder fulcrum, 2-1, fork, 14-1 connecting rod, 16, cam, 17, pivot, 18, cylinder, 19, roller, 20, pressing plate.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, plate cylinder 7 spindle noses are through in the wallboard hole, and cam 16 leans against on wallboard, and are enclosed within on the spindle nose of plate cylinder 7, by pressing plate 20 location that are fixed on the plate cylinder shaft end surface, pressing plate 20 is by a minute individual end face that is evenly distributed on the plate cylinder spindle nose.Make vertical plate cylinder 7 axis of cam 16 and can not move along the plate cylinder spindle nose, and can rotate around the plate cylinder spindle nose, cylinder 18 afterbodys are equipped with the cylinder fulcrum, cylinder can rotate around fulcrum, the cylinder fulcrum can be fixed by frame, fork 2-1 two ends be hinged on respectively on cylinder and connecting rod 14-1 on, the connecting rod two ends are hinged on respectively on fork 2-1 and cam 16, roller 19, copy roller 3 roll shiftings 1 and connecting rod 14 be corresponding being arranged in four holes of fork 2 respectively, can be around hole rotation separately, roller 19 cylindricals lean against on cam curved surface, spring base 13 is screwed on connecting rod 14, through the fulcrum 12 on fixing wallboard, on fulcrum 12, can stretch back and forth, spring 11 is through on spring base 13, be arranged between connecting rod 14 and fulcrum 12.
At machine when never printing state is converted to printing state, the piston rod of cylinder 18 stretches out, fork 2-1 rotates, drivening rod 14-1 the cam 16 that promotes to be contained on plate cylinder 7 spindle noses clockwise rotate around plate cylinder 7 centers, roller 19 transfers to and leans against cam 16 low spots from leaning against the high point of cam 16, thereby make 4 forks 2 respectively around roll shifting 1 central rotation, Compress Spring 11 stretches, 4 copy rollers lean against on plate cylinder 7, beginning is to plate cylinder 7 inkings, and the gap between each part all makes progress.When machine is converted to not printing state from printing state, action is with above-mentioned contrary.Due to the effect of cam low spot, the gap between each part also all makes progress.When copy roller 3 leans against on plate cylinder 7, when plate cylinder forwards entity in the copy roller position to from neutral, copy roller 3 will not be knocked and lifts, but directly is rolled on plate cylinder 7.So just solve the mechanism caused due to gap unstable, the problem of the excessive black thick stick of China ink amount can occur in mouth position, forme front, thereby improved the quality of printing.
