As shown in fig. 5, the ink replenishing mechanism 8 is further included, the ink replenishing mechanism 8 includes a fifth fixing frame 81, a fifth transmission rod 82, a fourth belt pulley group 83, a second sector gear 84, an eighth gear 85, a second rack 86, a second grooved sliding frame 87 and a replenishing box 88, the fifth fixing frame 81 is symmetrically arranged at the front and back of the right side of the top of the bottom plate 1, the fifth transmission rod 82 is rotatably connected between the middle parts of the fifth fixing frame 81, the fifth transmission rod 82 is connected with the transmission shaft of the first belt pulley group 33, the second sector gear 84 is rotatably connected between the upper sides of the fifth fixing frame 81, the fourth belt pulley group 83 is connected between the transmission shaft of the second sector gear 84 and the fifth transmission rod 82, the second grooved sliding frame 87 is symmetrically arranged at the left and right of the back of the top of the bottom plate 1, the second rack 86 is slidably arranged on each second grooved sliding frame 87, the eighth gear 85 is rotatably arranged at the, the eighth gear 85 is meshed with a second rack 86 on the right side and the second sector gear 84, a feeding box 88 is connected between the second racks 86, and elastic pieces are connected between the left side and the right side of the bottom of the feeding box 88 and the bottom plate 1.

The operator can directly place the can 9 on the left side of the belt of the first pulley set 33, and then start the motor 32 to work, so that the first transmission rod 45 rotates, the first transmission rod 45 rotates to drive the fourth transmission rod 68 to rotate through the second bevel gear set 62, the fourth transmission rod 68 rotates to drive the third transmission rod 65 to rotate through the third pulley set 63, the third transmission rod 65 rotates to drive the guide plate 67 to move back and forth through the crank rocker set 66, the guide plate 67 moves back and forth to drive the first connecting rod 71 to move up, down, up, back and down in sequence, when the first connecting rod 71 moves down first, the fixed block 72, the third return spring 73 and the printing block 74 are driven to move down, the left printing block 74 moves down to contact with the can 9, the fixed block 72 continues to move down, the third return spring 73 is compressed, so as to print the can 9, then the first sector gear 43 is meshed with the first gear 42, at this time, the first connecting rod 71 is reset to the initial state, and the printing block 74 is also reset to the initial state under the action of the third reset spring 73, at this time, the can 9 can be transported to the right, the worker can intermittently place the can 9 to be printed on the belt of the first pulley set 33, the first pulley set 33 rotates to drive the fifth transmission rod 82 to rotate through the fourth pulley set 83, the fifth transmission rod 82 rotates to drive the eighth gear 85 to rotate through the second sector gear 84, the eighth gear 85 rotates to drive the second rack 86 to move upwards, the second rack 86 moves upwards to drive the feeding box 88 to move upwards, the elastic element is stretched, the feeding box 88 moves upwards to perform the dye adding work on the printing block 74, at this time, the third reset spring 73 plays a buffering role, and then the second sector gear 84 rotates to be not meshed with the eighth gear 85, feed supplement box 88, second rack 86 and eighth gear 85 reset to initial condition under the effect of elastic component, when can 9 transported to right side printing block 74 front side, can 9 one side has been printed this moment, right side printing block 74 moves down alright carry out the printing work with can 9's another side, along with the continuous rotation of motor 32 output shaft, the staff only needs to put can 9, alright carry out the printing work to its two sides all, the whole back that finishes of printing of can 9, stop motor 32 work can.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
