The specific embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the offset press that possesses automatic stirring function of the present embodiment seals black groove and comprises black groove body 1, ink foundation roller 2, drive unit 3, Ink stirring stick 4, dust cover 5, pedestal 6, gauge tap 7 and pneumatic control circuit, wherein:
China ink groove body 1 is fixed on pedestal 6, ink foundation roller 2 is arranged on the interior for ink is taken out of of black groove body 1, Ink stirring stick 4 is arranged in black groove body 1 and is connected with drive unit 3, like this Ink stirring stick 4 under the driving of drive unit 3 at the interior stirring ink of black groove body 1, the utility model adopts drive unit 3 to drive Ink stirring stick 4 to move reciprocatingly to replace master worker to stir ink, can save manpower, and guarantee the stable amount out of ink in each ink-covered area in black groove, automaticity is high.Particularly, in the present embodiment, as shown in Figure 2, drive unit 3 comprises the source of the gas 31 being communicated with successively by appendix, filter 32, pressure-reducing valve 33, solenoid directional control valve 34 and cylinder assembly 35, the telescopic end of the piston rod 351 of cylinder assembly 35 is fixed on pedestal 6, the cylinder shell 352 of cylinder assembly 35 is fixedly connected with Ink stirring stick 4, between pressure-reducing valve 33 and solenoid directional control valve 34, be provided with flow speed control valve 36, on pedestal 6, be also provided with for controlling gauge tap 7 and the pneumatic control circuit of Ink stirring stick 4 movement travels, the position of the chute 51 on the position of gauge tap 7 and dust cover 5 matches, control accuracy is higher like this.Particularly, in pneumatic control circuit, control the electric drawings of solenoid directional control valve 34 commutations as shown in Figure 3, press shift knob SB1, stir lower stroke switch SQ2, SQ2 normally opened contact is closed, relay K M1 obtains electric, thereby the normally opened contact KM1 of relay K M1 is closed, normally-closed contact KM1 disconnects, it is electric that thereby the 1YA of solenoid directional control valve 34 obtains, cylinder shell 352 moves right, when moving to low order end, meets cylinder shell 352 travel switch SQ1, thereby travel switch SQ1 normally-closed contact disconnects, normally opened contact is closed, relay K M1 power-off, KM2 obtains electric, make the normally opened contact of KM2 closed, normally-closed contact disconnects, the 2YA of solenoid directional control valve 34 obtains electric, thereby realize the commutation of cylinder assembly 35, cylinder shell 352 is to left movement, when cylinder shell 352 moves to high order end, meet travel switch SQ2, realize the commutation again of cylinder assembly 35, thereby realize the iterative motion of cylinder shell 352, wherein pressure-reducing valve 33 is for adjusting cylinders output pressure, flow speed control valve 36 is for control cylinder movement velocity.
Ink stirring stick 4 comprise be positioned at black groove body 1 stir China ink 41, stir China ink 41 and be connected with drive unit 3 by connecting rod 42, stirring black 41 is cone, stir like this China ink 41 outer surface round and smooth, in whipping process, ink can flow through the surface of stirring black 41 smoothly, and mixing effect is more even.
As shown in Figure 1, Figure 4, Figure 5, the transparent component of dust cover 5 for being coupling on pedestal 6, can overturn, and the convenient ink that increases, makes the transparent amount that can observe at any time ink, supplements at any time; Dust cover 5 is provided with the chute 51 of perforation dust cover 5 inwalls and outer wall, and Ink stirring stick 4 is slidably installed in this chute 51, and dust cover 5 can separate the ink in ink fountain and air, thereby prevents that ink is by air pollution.
To sum up, by pneumatic control circuit control cylinder housing 352, move reciprocatingly, again by cylinder shell 352 drive Ink stirring sticks 41 li of black groove body move reciprocatingly make black groove body 1 in the amount of each position ink consistent, guaranteeing has enough ink on ink foundation roller 2, what reduces workman's workload from, save manpower, pneumatic control circuit is simple, and plant maintenance is convenient; By Ink stirring stick 4, in 1 li of reciprocating motion of black groove body, make ink produce dynamic pressure to ink foundation roller 2, increase amount out of ink; Dust cover 5 can effectively prevent that ink is contaminated, improves the quality of printing.
