Abstract
The utility model discloses an offset printing machine roller with a new type of array corner structure, which includes a printing roller, a rubber roller and an impressing roller in parallel with a rotating shaft. The printing roller is above the rubber roller, and the printing roller is under the rubber roller. Included angle of the tie line between axis of the impressing roller and axis of the rubber roller and horizontal paper feeding direction is larger than 90 degrees, and included angle of the tie line between axis of the printing roller and axis of the rubber roller and horizontal paper feeding direction is between 90 degrees and 110 degrees. Therefore the resultant force of the printing roller and impressing roller to the rubber roller is small, and rotating shaft of the rubber roller receives relatively small friction, which extends service life of the offset printing machine, provides more stable printing quality and facilitates operation, debugging and maintenance.
Description
Technical field
The utility model relates to the cylinder in offset printing press with novel arrangement angles structure, belongs to the offset press field.
Background technology
Along with the progress of science and technology, offset printing develops rapidly in press with its unique advantage and has occupied critical role.Offset press mainly is by the pressure between three cylinders in printing process, and the extruding of the printed matter on the forme by plate cylinder and blanket cylinder forwarded on the blanket, by the extruding of blanket cylinder and impression cylinder, is transferred on the paper by blanket then.
The conventional arrangement structure of present most cylinder in offset printing press as shown in Figure 2, comprise the plate cylinder 1 that turning cylinder is parallel to each other, blanket cylinder 2, impression cylinder 3, described plate cylinder 1 is positioned at the top of blanket cylinder 2, described impression cylinder 3 is positioned at the below of blanket cylinder 2, and the line of the axis of the axis of described impression cylinder 3 and blanket cylinder 2 and horizontal paper feed direction angle are greater than 90 °, the line of the axis of the axis of described plate cylinder 1 and blanket cylinder 2 and horizontal paper feed direction included angle A are greater than 135 °, this cylinder in offset printing press arrangement architecture level takes up space greatly, making a concerted effort of plate cylinder 1 and 3 pairs of blanket cylinders 2 of impression cylinder is bigger, cause blanket cylinder 2 rotating shaft excessive wears easily, reduce the service life of offset press, and cause the instability of printing quality easily, and make operation, debugging, maintenance difficult.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of take up space little, long service life, printing quality stable; And operation, debugging, the cylinder in offset printing press with novel arrangement angles structure easy to maintenance.
For achieving the above object, the technical solution of the utility model is: the cylinder in offset printing press with novel arrangement angles structure, comprise plate cylinder, blanket cylinder, impression cylinder that turning cylinder is parallel to each other, described plate cylinder is positioned at the top of blanket cylinder, described impression cylinder is positioned at the below of blanket cylinder, and the line of the axis of described impression cylinder and the axis of blanket cylinder and horizontal paper feed direction angle are greater than 90 °, and the line of the axis of described plate cylinder and the axis of blanket cylinder and the angle of horizontal paper feed direction are 90 °-110 °.
As a kind of improvement, the line of the axis of described plate cylinder and the axis of blanket cylinder and the angle of horizontal paper feed direction are 98 °.
Owing to adopt technique scheme, cylinder in offset printing press with novel arrangement angles structure, comprise the plate cylinder that turning cylinder is parallel to each other, blanket cylinder, impression cylinder, described plate cylinder is positioned at the top of blanket cylinder, described impression cylinder is positioned at the below of blanket cylinder, and the line of the axis of described impression cylinder and the axis of blanket cylinder and horizontal paper feed direction angle are greater than 90 °, the line of the axis of described plate cylinder and the axis of blanket cylinder and the angle of horizontal paper feed direction are 90 °-110 °, thereby less with joint efforts to blanket cylinder of plate cylinder and impression cylinder, the friction that the blanket cylinder rotating shaft is subjected to is less, thereby improved the service life of offset press, and printing quality stable and make operation, debugging, keep in repair convenient.
