Abstract
The utility model discloses a dual-color offset printing machine, which comprises a first printing device, a second printing device and a paper passing device, wherein the paper passing device consists of a paper passing roller; a row of gripper devices are arranged on the paper passing roller; the paper passing roller is adjacent to the impression rollers of the first printing device and the second printing device; and the linear velocities of the surfaces of the rollers of the first printing device and the second printing device as well as the linear velocity of the surface of the paper passing roller are the same. Under the conditions that the structure is simplified and the cost is lowered, the dual-color offset printing machine can not only ensure the working efficiency of the original offset printing machine, but also lead the paper gripping time to be reduced from the original four times to twice in the paper passing process, and the accumulated error is reduced to 50%, so as to improve the precision of dual-color chromatography greatly.
Description
Technical field
The utility model relates to the offset press technical field, relates in particular to a kind of suitable two color offset press that single-sheet stationery is carried out two color printing.
Background technology
Light-duty single-colour offset press technology is comparative maturity, manufacturing and purchase cost are low, wherein the box-like single-colour offset press of three cylinder group is exactly a kind of offset press of suitable single-sheet stationery printing, and it generally includes paper feed, ink-feeding device, printing equipment, delivery device and beats the sign indicating number device.Described printing equipment comprises the plate cylinder that forme is installed, and the blanket cylinder of the described forme pattern of transfer printing is printed onto impression cylinder on the single-sheet stationery with the pattern that is transferred to described blanket cylinder.
At present, the common structure of two color offset press is that two printing equipments are organically combined by the transfer device, realizes two color printing.But known transfer device mostly adopts three to hold paper roll in the month, and each is held in the month and holds the unlatching sequentially and closed under the control of cam mechanism of tooth mechanism on the paper roll in the month, thereby realizes the transmission of paper.In order to guarantee synchronously, single-sheet stationery is delivered to back one printing equipment from last printing equipment need hold the paper process in the month through four times, and its accumulated error will reduce the degree of accuracy of two kinds of color chromatographys.And, this transfer apparatus structure complexity, floor space is big, and the cost height has reduced the price advantage of two color offset press.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of two color offset press is provided, and this offset press effectively reduces the transfer error by compact structure and lower cost, has improved the degree of accuracy of chromatography.
For solving the problems of the technologies described above, the technical solution of the utility model is: two color offset press, comprise first printing equipment and second printing equipment, described first printing equipment and second printing equipment comprise a plate cylinder that forme is installed respectively, the blanket cylinder of a described forme pattern of transfer printing, pattern that will be transferred to described blanket cylinder are printed onto the impression cylinder on the single-sheet stationery; Transfer device, described transfer device are arranged between first printing equipment and second printing equipment, and described transfer device is made of a transfer roller, and described transfer roller is provided with row's gripper device; The described transfer roller impression cylinder with first printing equipment and second printing equipment respectively is adjacent, and the linear velocity of three's cylinder surface is identical.
Wherein, the rotating speed of described transfer roller and described two impression cylinders is identical and the diameter of cylinder three is identical.
After having adopted technique scheme, the beneficial effects of the utility model are: the transfer device is made of a transfer roller, described transfer roller is provided with row's gripper device, the described transfer roller impression cylinder with first printing equipment and second printing equipment respectively is adjacent, and the linear velocity of three's cylinder surface is identical, therefore, single-sheet stationery is delivered to second printing equipment from first printing equipment and is reduced to twice and holds paper in the month by holding paper for original four times in the month, its accumulated error reduces half, thereby has improved the degree of accuracy of two kinds of color chromatographys greatly.Moreover,, thereby make the structure of complete machine become compact more, reduced floor space, and reduced production cost, reduced the consumption of using power because the transfer device reduces to one by three original cylinders.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1. paper feed; 2. pass a bridge; 3. first printing equipment; 4. transfer roller; 5. second printing equipment; 6. beat the sign indicating number device; 7. delivery device; 41. gripper device; A. plate cylinder; B. blanket cylinder; C. impression cylinder.
The specific embodiment
As shown in drawings, a kind of two color offset press, it comprises paper feed 1, gap bridge 2, first printing equipment 3, transfer roller 4, second printing equipment 5, makes sign indicating number device 6 and delivery device 7, beats a sign indicating number device 6 and belongs to the apolegamy parts.
Transfer roller 4 has constituted the transfer device between first printing equipment 3 and second printing equipment 5.Only be provided with row's gripper device 41 on the described transfer roller 4.
The transfer roller 4 impression cylinder c with first printing equipment and second printing equipment respectively is adjacent, and the linear velocity of three's cylinder surface is identical.Preferably, the rotating speed of described transfer roller 4 and described two impression cylinder c is identical and the diameter of cylinder three is identical.
As inventor of the present utility model, creatively adjusted the arrangement mode of each cylinder in two printing equipments and the transfer device, under the situation of simplified structure, not only guaranteed the operating efficiency of original offset press, and make the transfer process be reduced to twice and hold paper in the month by holding paper for original four times in the month, its accumulated error reduces half, thereby has improved the degree of accuracy of two kinds of color chromatographys greatly.On the other hand, the transfer device reduces to one by three original cylinders, thereby makes the structure of complete machine become compact more, reduced floor space, and reduced production cost, and reduced the consumption of using power, improved the price advantage of two color offset press greatly.
