It specifically is embodiment
Accompanying drawing has been represented technical scheme of the present invention and embodiment, further describes each relevant details and operation principle thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1,2, this kind printing machine anilox roll rotating striking gear, be installed on the board 1 of printing machine, the print couple that board 1 is provided with comprises roller platen 2, forme roller 3 and anilox roll 4, the axle head of roller platen 2 is provided with impression travelling gear 5, the axle head of forme roller 3 is provided with forme travelling gear 6, described printing machine anilox roll rotating striking gear comprises travelling gear 7 and the black gear 11 of fortune that is located at anilox roll 4 left and right sides axle heads, described travelling gear 7 is set on the left side axle head of described anilox roll 4 by bearing is rotatable, travelling gear 7 and described forme travelling gear 6 transmissions engagement, the black gear 11 of described fortune is set on the right side axle head of described anilox roll 4 by bearing is rotatable, transport black gear 11 and the transmission gear 12 mutual transmission engagements of being located at fortune Mo Mada 13 axle heads, the left and right sides axle head of described anilox roll 4 also is fixedly connected with fixed cover 9 and 14 respectively, be respectively equipped with on the outside end face of described travelling gear 7 and the black gear 11 of fortune can about the ratchet 8 and 15 stirred, described fixed cover 9 is provided with the draw-in groove 10 that can block for the ratchet of ratchet 8, described fixed cover 14 is provided with the draw-in groove 16 that can block for the ratchet of ratchet 15, ratchet has two ratchets, two ratchets respectively by draw-in groove promote fixedly interplanting clockwise with rotate counterclockwise.
The present invention is work like this: when the pattern of printing front, roller platen 2 clockwise rotates, thereby transmission forme roller 3 rotates, drive travelling gear 7 and be clockwise active rotation state, go to right side (as shown in Figure 3) with the ratchet 8 on the described transmission gear face this moment, places in the draw-in groove 10 of fixed cover 9, makes the ratchet of ratchet 8 drive fixed cover 9, because fixed cover 9 is to fixedly connected with anilox roll 4, so anilox roll is also rotated toward the clockwise direction; Because anilox roll is rotated toward the clockwise direction, must go to right side (as shown in Figure 4) equally this moment with the ratchet 15 on black gear 11 end faces of described fortune, place in the draw-in groove 16 of fixed cover 14, because the black gear 11 of fortune is inactive state (not rotating), so fixed cover 14 can not drive ratchet 15, ratchet 15 is skidded on the draw-in groove 16 of fixed cover;
When printing machine shuts down, in order not allow the printing ink on the anilox roll 4 become dry, must allow anilox roll continue to rotate toward the clockwise direction, start fortune Mo Mada 13 this moment, fortune Mo Mada drives and transmits gear 12, and transmit gear 12 and transport black gear 11 and be meshing with each other, therefore transporting black gear is the state that initiatively clockwise rotates, so the ratchet of transporting on the black gear 11 15 can drive fixed cover 14, because fixed cover 14 is to fixedly connected with anilox roll 4, so anilox roll rotates toward the clockwise direction, is inactive state (not rotating) because printing machine stops the described travelling gear 7 in back, so fixed cover 9 can not drive ratchet 8, ratchet 8 is skidded on the draw-in groove 10 of fixed cover 9.
When printing reverse side pattern, please cooperate Fig. 5 and Fig. 6, roller platen 2 rotates counterclockwise, thereby driving forme roller 3 rotates, drive travelling gear 7 and be counterclockwise active rotation state, go to left side (as shown in Figure 5) with the ratchet on the travelling gear 78 this moment, and the ratchet 15 that will transport simultaneously on the black gear 11 also goes to left side (as shown in Figure 6), and principle is the same with positive printing; The rotation direction of the Mo Mada of change fortune simultaneously then can make anilox roll towards counterclockwise rotating (rotation direction of fortune Mo Mada is controlled by the forward-reverse switch on the printing machine, and is not shown in the figures).
Therefore by said apparatus of the present invention, the ratchet that only need stir anilox roll left and right sides axle head just can realize changing the rotation direction of anilox roll, and do not need the dismounting anilox roll, influence accuracy of machines, and production efficiency is improved greatly, reduce operative employee's labour intensity simultaneously, make the conversion direction program of rotating just be able to summary.
