Abstract
The utility model discloses a forme adjusting mechanism for a lithographic press. The forme adjusting mechanism comprises a gripper-edge-side forme clamp and a tail-end-side forme clamp, which are arranged on a forme cylinder. The drag-and-large-side forme clamp consists of a left forme clamp, an intermediate forme clamp and a right forme clamp, the left and the right forme clamps are respectively connected to two ends of the intermediate forme clamp through a lead screw, and the turning directions of threads on two ends of the lead screw are opposite to each other. According to the forme adjusting mechanism, a register difference problem caused by deformation of paper and a fan-shaped expansion problem of the paper can be effectively solved.
Description
Technical field
The utility model relates to a kind of forme governor motion that is used for offset press.
Background technology
Offset press is when printing, and paper rolls through blanket cylinder and impression cylinder, adds that paper has absorbed fountain solution, makes that paper front and back size is variant, therefore can bring influence to chromatography.Ordinary circumstance is the chromatography line ability alignment that causes top of form, and the rear portion can not alignment.
Head it off all is through regulating the water yield of printing, perhaps regulating the handing-over of paper etc. at present.The mode of regulating pondage can be brought certain influence to the effect of printing.And the handing-over of adjusting paper then will be regulated the axial delivery position of gritting one's teeth, and the adjusting difficulty is big, and easily printing precision is impacted.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, a kind of forme governor motion that is used for offset press to be provided, and it can solve the register trouble problem that causes because of paper distortion effectively, can effectively solve the fan-shaped expansion problem of paper.
The technical scheme that realizes above-mentioned purpose is: a kind of forme governor motion that is used for offset press comprises the seaming side clamp bar that is installed on the plate cylinder and drags side clamp bar slightly.Saidly drag slightly that the side clamp bar is made up of left side clamp bar, middle clamp bar and the right clamp bar, said left side clamp bar and the right clamp bar through a screw mandrel be connected said in the middle of the two ends of clamp bar, and the thread rotary orientation at two of said screw mandrel is opposite.
The above-mentioned forme governor motion that is used for offset press, wherein, said left side clamp bar, middle clamp bar and the right clamp bar all are removably mounted on the same base plate, and this base plate is fixed on the said plate cylinder.
The technical scheme of the forme governor motion that is used for offset press of the utility model; Through the clamp bar on the plate cylinder is designed to syllogic; And the clamp bar on both sides can move axially by middle relatively clamp bar through regulating screw mandrel; Thereby to forme drag slightly that side stretches, make forme that a distortion in advance arranged, thus the compensation Deformation of Paper.Prevent the influence that the fan-shaped expansion of paper causes printing, can effectively solve the register trouble problem that causes because of paper distortion, and simple in structure, the influence to printing easy to adjust.
Description of drawings
Fig. 1 is the structural representation of the forme governor motion that is used for offset press of utility model;
Fig. 2 is that F-F among Fig. 1 is to view.
The specific embodiment
In order to understand the technical scheme of the utility model better, below through embodiment particularly and combine accompanying drawing at length to explain:
See also Fig. 1 and Fig. 2; A kind of forme governor motion that is used for offset press of the utility model; Comprise the seaming side clamp bar 20 that is installed on the plate cylinder 10 and drag side clamp bar 30 slightly, wherein, dragging slightly, side clamp bar 30 is made up of left side clamp bar 31, middle clamp bar 32 and the right clamp bar 33.The two ends of clamp bar 32 in the middle of left side clamp bar 31 is connected through a screw mandrel 34 with the right clamp bar 33, and the thread rotary orientation at two of screw mandrel 34 is opposite.
In addition, left side clamp bar 31, middle clamp bar 32 and the right clamp bar 33 all are installed on the same base plate 35 through screw 36, and this base plate 35 is fixed on the plate cylinder 10.
During adjustment, loosening fixedly left side clamp bar 31 and the hold-down screw 36 of the right clamp bar 33 with base plate 35, that rotates left side clamp bar 31 and middle clamp bar 32 and the right clamp bar 33 and middle clamp bar 32 is connected screw mandrel 34.Because the thread rotary orientation at screw mandrel 34 two ends is opposite, so it can change when regulating and drag the left and right limit of side clamp bar 31,33 slightly and the axial distance that drags clamp bar 32 in the middle of the side slightly, thus make forme drag slightly side also " to be drawn " to grow by vertically.
During printing, dragging the deviation of side chromatography line slightly, judging the Deformation of Paper degree, will drag slightly side clamp bar 30 to make corresponding adjustment then, can effectively solve the fan-shaped expansion problem of paper according to printing.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
Claims (2)
1. forme governor motion that is used for offset press; Comprise the seaming side clamp bar that is installed on the plate cylinder and drag side clamp bar slightly; It is characterized in that, saidly drag slightly that the side clamp bar is made up of left side clamp bar, middle clamp bar and the right clamp bar, said left side clamp bar and the right clamp bar through a screw mandrel be connected said in the middle of the two ends of clamp bar; And the thread rotary orientation at two of said screw mandrel is opposite.
2. the forme governor motion that is used for offset press according to claim 1 is characterized in that said left side clamp bar, middle clamp bar and the right clamp bar all are removably mounted on the same base plate, and this base plate is fixed on the said plate cylinder.
