Abstract
The utility model relates to a printing four-roller structure arranged in a straight line, which comprises an upper printing plate roller, an upper rubber roller, a lower rubber roller and a lower printing plate roller which are arranged in sequence from top to bottom; an upper clutch pressure plate is arranged on the upper printing plate roller, a middle clutch pressure plate is arranged on the lower rubber roller, a lower clutch pressure plate is arranged on the lower printing plate roller, the upper clutch pressure plate is connected with an upper eccentric sleeve to form an upper clutch mechanism, the middle clutch pressure plate is connected with a middle eccentric sleeve to form a middle clutch mechanism, the lower clutch pressure plate is connected with a lower eccentric sleeve to form a lower clutch mechanism, and the upper clutch pressure plate, the middle clutch pressure plate and the lower clutch pressure plate are connected through a connecting rod; go up the central line of printing plate roller, go up rubber roll, lower printing plate roller and become a straight line M, and the contained angle between straight line M and the vertical line N is alpha, and the separation and reunion of this structure roller is accurate, steady, the impact is minimum, has alleviateed and has strikeed the thick stick to make and strikeed the blank position that the thick stick position appears between the space of a whole page, thereby improved the quality of printed matter.
Description
Technical Field
The utility model relates to an offset press technical field, concretely relates to four roller structures of printing of inline.
Background
The arrangement of four printing rollers is a key part of an offset press, the four printing rollers of the existing book and periodical printing press adopt a roll-to-roll type arrangement mode of a vertical paper feeding type, and the arrangement structure has the defects that the component forces in the vertical direction of the upper rubber roller and the lower rubber roller cannot be balanced, and because the rollers are processed differently, the two rubber rollers are stressed inconsistently, so that the printing overprinting is inaccurate, an impact bar is easy to generate on the page surface, and the printing quality is influenced.
Disclosure of Invention
The utility model discloses aim at overcomes exist among the prior art not enough, provides a rational in infrastructure, and printing quality is high, four roller inline arrangement structures of printing that the rejection rate is low. In particular, the method comprises the following steps of,
a printing four-roller structure arranged in a straight line is characterized in that,
the structure comprises an upper printing plate roller, an upper rubber roller, a lower rubber roller and a lower printing plate roller which are sequentially arranged from top to bottom;
an upper clutch pressure plate is arranged on the upper printing plate roller, a middle clutch pressure plate is arranged on the lower rubber roller, a lower clutch pressure plate is arranged on the lower printing plate roller,
the upper clutch pressure plate is connected with the upper eccentric sleeve to form an upper clutch mechanism, the middle clutch pressure plate is connected with the middle eccentric sleeve to form a middle clutch mechanism, the lower clutch pressure plate is connected with the lower eccentric sleeve to form a lower clutch mechanism, and the upper clutch pressure plate, the middle clutch pressure plate and the lower clutch pressure plate are connected through a connecting rod;
the center connecting lines of the upper printing plate roller, the upper rubber roller, the lower rubber roller and the lower printing plate roller form a straight line M, the included angle between the straight line M and the vertical line N is alpha,
further said α is an acute angle.
Has the advantages that:
the utility model has the advantages of as follows:
the clutch pressure plate between the rollers of the mechanism adopts a link mechanism to replace the prior sector gear, eliminates the gap, and has the advantages of minimum force when the rollers operate, moderate stability under a working state, accurate and stable clutch of the rollers, minimum impact, reduction of impact bars, and improvement of the quality of printed products due to the fact that the impact bars are positioned at the blank positions between the layout of the plates.
Drawings
Fig. 1 is a schematic view of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will describe in further detail common embodiments of the present invention with reference to the accompanying drawings.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
As shown in fig. 1: a printing four-roller structure in linear arrangement comprises an upper printing plate roller 1, an upper rubber roller 2, a lower rubber roller 3 and a lower printing plate roller 4 which are sequentially arranged from top to bottom;
an upper clutch pressure plate 6 is arranged on the upper printing plate roller 1, a middle clutch pressure plate 8 is arranged on the lower rubber roller 3, a lower clutch pressure plate 9 is arranged on the lower printing plate roller 4,
the upper clutch pressure plate is connected with the upper eccentric sleeve 5 to form an upper clutch mechanism, the middle clutch pressure plate 8 is connected with the middle eccentric sleeve 10 to form a middle clutch mechanism, the lower clutch pressure plate 9 is connected with the lower eccentric sleeve 11 to form a lower clutch mechanism, and the upper clutch pressure plate, the middle clutch pressure plate and the lower clutch pressure plate are connected through a connecting rod 7;
the center connecting lines of the upper printing plate roller 1, the upper rubber roller 2, the lower rubber roller 3 and the lower printing plate roller 4 form a straight line M, the included angle between the straight line M and the vertical line N is alpha, and the alpha is an acute angle.
The four rollers are arranged on the frame through eccentric sleeves and bearing seats, the rubber roller serves as a reference roller, the clutch pressure plate is connected with the eccentric sleeves, and the connecting rod is connected with the clutch pressure plate.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
