Compared with prior art, the present invention is simple in structure, can realize the conversion of two kinds of mode of printings on same printing element, two kinds of mode of printings share one group of rubber stick and the roller of undertaking the printing of, and not only reduce the wasting of resources, and fund input are few, floor space is little, and high efficiency is widely applicable.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
In figure: inking roller 1, undercarriage cylinder 2, ink roller undercarriage 3, roller 4, undercarriage connecting rod 5, undercarriage fork 6, swinging axle 7, air cylinder connecting rod 8, swinging arms of cylinder 9, flexo China ink groove 10, anilox roll folding cylinder 11, anilox roll 12, flexo support plate 13, guide groove 14, gripper shoe 15, the roller 16 of undertaking the printing of, rubber stick 17, black groove folding cylinder 18.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
Referring to accompanying drawing 1, what this figure was shown is the structure of gripper shoe inboard, and what wherein dotted line represented is the structure in the gripper shoe outside, and what chain-dotted line was represented is the transmission track of offset printing printing ink.The offset printing of this rotary press of offset printing tool, flexo quick switching device comprise offset printing mechanism, flexible printer structure, and undertake the printing of roller and the rubber stick of engaged transmission.Offset printing mechanism and flexible printer structure are arranged on same group of gripper shoe 15.
Offset printing mechanism comprises that the inking roller 1, roller 4 and the ink roller undercarriage that are arranged on gripper shoe 15 inboards form; Roller gear in roller 4 and the squeegee meshed transmission gear in rubber stick 17.The ink roller undercarriage forms and comprises the ink roller undercarriage 3 and the cylinder 2 that rises and falls that is arranged on the gripper shoe outside that is arranged on gripper shoe 15 inboards, and an end of ink roller undercarriage 3 is by transmission mechanism and cylinder 2 interlocks that rise and fall.Transmission mechanism comprises undercarriage connecting rod 5, undercarriage fork 6, air cylinder connecting rod 8, swinging arms of cylinder 9 and swinging axle 7, wherein: undercarriage connecting rod 5 and undercarriage fork 6 are hinged, the other end of undercarriage connecting rod 5 and ink roller undercarriage bottom are hinged, and the other end of undercarriage fork 6 and swinging bush load connect.Air cylinder connecting rod 8 and swinging arms of cylinder 9 are hinged, and the push rod of the other end undercarriage cylinder of air cylinder connecting rod 8 connects, and the other end of swinging arms of cylinder 9 is connected with swinging axle 7 suits.The ink roller undercarriage arranges along the roller excircle, and 1 of inking roller is contained on ink roller undercarriage 3.
The flexible printer structure comprises anilox roll 12, flexo China ink groove 10, flexo support plate 13 and anilox roll folding cylinder 11, the anilox roll gear in anilox roll 12 and rubber stick 17 meshed transmission gear that are arranged on gripper shoe 15 inboards.Anilox roll folding cylinder 11 is fixed on the side of gripper shoe 15, and the shaft extension end of cylinder is fixedly connected with flexo support plate 13.One guide groove 14 is set above flexo support plate 13, and 10 of grooves of flexo China ink are contained in guide groove 14, and are connected with black groove folding cylinder 18 on being fixed on flexo support plate 13.
This device is installed in rotary printing machine on any one group of printing element, does not affect prototype structure.Offset printing mechanism and flexible printer structure are controlled separately, single movement.
The operation principle of this device is:
1, anilox roll folding cylinder is regained, and the flexo support plate moves to right together with anilox roll and the flexo China ink groove of its dress, and the anilox roll gear breaks away from engagement with the squeegee gear, and flexo mechanism does not participate in printing.The undercarriage cylinder stretches out, the swinging arms of cylinder that air cylinder connecting rod is hinged and the fixing swinging axle of suit thereof swing clockwise, be fixed on undercarriage fork on swinging axle and hinged undercarriage connecting rod, ink roller undercarriage counter-clockwise swing thereof, low spot on the ink roller undercarriage contacts with the bearing at each inking roller two ends, inking roller falls, and with roller applying transmission, printing ink is transferred to squeegee through inking roller, roller, the printing material that squeegee is transferred to printing ink squeegee and undertaken the printing of and pass between roller again, offset printing is completed;
2, undercarriage cylinders retract, the swinging arms of cylinder that air cylinder connecting rod is hinged and the fixing swinging axle counter-clockwise swing of suit thereof, being fixed on undercarriage fork on swinging axle and hinged undercarriage connecting rod, ink roller undercarriage thereof swings clockwise, height point on the ink roller undercarriage contacts with the bearing at each inking roller two ends, inking roller is lifted, throw off transmission with roller, offset printing ink supply process finishes.Then the shaft extension end of anilox roll folding cylinder is released, the flexo support plate moves to left together with anilox roll and the flexo China ink groove of its dress, anilox roll gear and the engagement of squeegee gear, anilox roll passes to squeegee with the printing ink in flexo China ink groove, the printing material that squeegee is transferred to printing ink squeegee and undertaken the printing of and pass between roller again, flexo is completed for printing.
