Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: a carbon ink printing device, including a base 1, a frame 2 fixedly connected to the outer side above the base 1, an ink cartridge 3 fixedly connected to the inner side above the base 1, a first roller 4 provided in the middle inner side of the frame 2, a printing area 6 provided on the outer surface of the first roller 4, a second roller 5 provided above the first roller 4, one end of the first roller 4 is fixedly connected with a reciprocating mechanism 7, and a pushing mechanism 8 is provided outside the reciprocating mechanism 7;

[0023] The reciprocating mechanism 7 includes a rotating disk 701 fixedly connected to one end of the first material rolling cylinder 4. Inside the rotating disk 701, there is a first guiding groove 706. Above the first guiding groove 706, there is a second guiding groove 702 communicating with it. Inside the first guiding groove 706, there is a first guiding rod 703. Inside the base 1, there is a first hole 704. Inside the first hole 704, there is a push rod 705. The push rod 705 is fixedly connected to the first guiding rod 703. The external structure of the first guiding groove 706 is arc-shaped, and the cooperation mode between the first guiding groove 706 and the first guiding rod 703 is clearance fit. The external structure of the second guiding groove 702 is arc-shaped, and the cooperation mode between the second guiding groove 702 and the first guiding rod 703 is clearance fit. The arc-shaped orientation of the first guiding groove 706 is the same as that of the second guiding groove 702, and the horizontal height of the second guiding groove 702 is the same as that of the printing area 6. The two side surfaces of the first material rolling cylinder 4 on both sides with respect to its axis are in contact with the inner side surface of the ink cartridge 3, so that when the first guiding rod 703 moves to the inside of the second guiding groove 702, it will move upward.

[0024] The pushing mechanism 8 includes a connecting plate 801 fixedly connected to the outside of the push rod 705. Inside the connecting plate 801, there is a guiding hole 802. Inside the frame 2, there is a third guiding groove 803. Inside the guiding hole 802, there is a second guiding rod 804. Inside the third guiding groove 803, there is a third guiding rod 805. The second guiding rod 804 is fixedly connected to the third guiding rod 805. The lower end of the second guiding rod 804 is fixedly connected with a pressing plate 806. The external structure of the guiding hole 802 is an inclined straight line shape, and the cooperation mode between the guiding hole 802 and the second guiding rod 804 is clearance fit. The external structure of the third guiding groove 803 is a horizontal straight line shape, and the cooperation mode between the third guiding groove 803 and the third guiding rod 805 is clearance fit. And the external structure of the third guiding rod 805 is a cuboid, so that when the guiding hole 802 moves up and down, it will push the second guiding rod 804 and the third guiding rod 805 to move towards the middle or towards both sides. The outer side surface of the pressing plate 806 is in contact with the inner side surface of the ink cartridge 3, so that the pressing plate 806 can push the ink towards the middle.

[0025] When the first rolling cylinder 4 and the second rolling cylinder 5 rotate, they drive the rotating disk 701 fixedly connected to the first rolling cylinder 4 to rotate, causing the first guiding groove 706 and the second guiding groove 702 to rotate. Since the arc-shaped orientation of the first guiding groove 706 is the same as that of the second guiding groove 702, and the horizontal height of the second guiding groove 702 is the same as the horizontal height of the printing area 6, when the printing area 6 approaches the ink cartridge 3, the first guiding rod 703 moves to the inside of the first guiding groove 706, and the first guiding rod 703 is pushed by the trajectory of the first guiding groove 706 to move upward along the trajectory of the first hole 704, driving the connecting plate 801 to move upward and driving the guiding hole 802 to move upward. Since the external structure of the guiding hole 802 is an inclined straight line, and the cooperation mode between the guiding hole 802 and the second guiding rod 804 is a clearance fit, the external structure of the third guiding groove 803 is a horizontal straight line, and the cooperation mode between the third guiding groove 803 and the third guiding rod 805 is a clearance fit, and the external structure of the third guiding rod 805 is a cuboid, the second guiding rod 804 and the third guiding rod 805 are pushed by the edge of the guiding hole 802 to move towards the middle along the trajectory of the third guiding groove 803, driving the pressing plate 806 to move towards the middle, causing the ink to move towards the middle. After the pressing plate 806 contacts the outer side of the first rolling cylinder 4, the ink is under pressure, causing the bubbles to burst and overflow, reducing the possibility of bubbles adhering to the printing area 6 and reducing the appearance of white dots, thereby improving the printing quality.
