At this time, the paper is not subjected to force, so that the paper can be kept flat between the sheet plate 67 and the paper pressing paper, thereby improving the printing effect.

[0032] A drying structure 7 is provided on the bottom side of the slide bar fixing plate 64. The drying structure 7 includes a slide groove bar 71, a slide bar groove 72, a linkage rod 73, and an arc wave block 74. The slide groove bar 71 is slidably connected to the outer side surface of the vertical slide bar 65, the slide bar groove 72 is opened on the side of the slide groove bar 71, the linkage rod 73 is arranged on the inner side of the slide bar groove 72, and the arc wave block 74 is fixedly connected to the top surface of the inner wall of the slide bar groove 72. The slide bar groove 72 runs from one side of the slide groove bar 71 to the other side, the linkage rod 73 is fixedly connected to the print head 9, and the arc wave block 74 and the linkage rod 73 are in contact with each other. The slide groove bar 71 moves up and down to drive the external heating tube installed on the bottom surface to move up and down. The up and down movement prevents the heating tube from heating the undried ink on the paper, allowing the ink to dry, and the slide groove bar 71 moves up and down to keep a distance from the paper to prevent the paper from being damaged by scalding.

[0033] Working principle: after the print head 9 has been used for a period of time, the ink sprayed from the print head 9 accumulates and condenses over time, blocking the inkjet hole, which will affect the uniformity of inkjet. The reciprocating screw 2 is driven by an external motor to rotate, so that the moving end 8 keeps reciprocating along the reciprocating screw 2 until the bottom surface of the print head 9 contacts the liquid-absorbing cotton plate 42 on the inner side of the placement groove 41, and the top surface of the liquid-absorbing cotton plate 42 contacts the cleaning brush strip 43 to clean the inkjet hole of the print head 9. At the same time, when the print head 9 approaches one side of the placement groove 41, the print head 9 will apply pressure to the pressure push rod 49, so that the pressure push rod 49 is pushed and squeezes the spring, so that the pressure push rod 49 pushes the connected The side plate 48 of the solid rod drives the wave rod 47 to move, so that the wave rod 47 moves and applies pressure to the vibration convex strip 46. The vibration convex strip 46 is pressed, which causes the connected vibration plate 45 to squeeze the elastic arc plate 44. The elastic arc plate 44 is pressed, and the liquid in the liquid-absorbing cotton plate 42 is squeezed out through the cleaning brush strip 43. When the wave rod 47 moves over the vibration convex strip 46, the elastic arc plate 44 recovers its deformation and pushes the vibration plate 45 to reset. In addition, the up and down movement of the vibration plate 45 causes the adjacent elastic arc plate 44 and the lower liquid solid plate 410 to vibrate. Through the vibration, the liquid in the bottle on the lower liquid solid plate 410 flows out to the liquid-absorbing cotton plate 42, so that the cleaning brush strip 43 can wipe the printing nozzle 9.

[0034] The local placement plate 56 is pressed down by hand to pull the spring, and the paper is placed on the local placement plate 56, so that the local placement plate 56 moves upward under the action of the spring elastic force, and the paper on the top surface is pressed against the bottom surface of the paper buckling block 510. At this time, the paper surface will contact the roller 54. When the roller 54 rotates, it drives the top paper into the paper guide side plate 3. After the paper here is completely entered into the paper guide side plate 3, the remaining paper will push the local placement plate 56 upward under the action of the spring elastic force, and the stacked paper moves upward to press against the paper buckling block 510, so as to realize the function of automatic paper filling. The plane of the plate 3 limits the paper thickness, and limits a single paper from entering the paper guide side plate 3, thereby preventing paper jams. At the same time, when the paper roller 54 rotates to drive two or more sheets of paper into the paper guide side plate 3, the thickness between the paper roller 54 and the paper guide side plate 3 increases, which causes the paper roller 54 to move upward under the influence of the thickness, so that the roller shaft 59 connected to the paper roller 54 applies pressure to the connecting frame 53, so that the connecting frame 53 deflects around the node where the connected flip bar 51 and the paper guide side plate 3 are connected, so that the flip bar 51 drives the limiting arc plate 52 to deflect, so that the limiting arc plate 52 buckles all the paper to prevent paper jams;

[0035] When the paper is fed to the top of the flat plate 67 by the paper roller 54, the driving turntable 10 connected to the reciprocating screw 2 rotates to drive the belt 61 to rotate, so that the belt 61 drives the roller shaft 59, the paper pressing wheel 62 and the guide wheel 63 to rotate, and the rotation of the paper pressing wheel 62 drives the paper reel 68 to rotate, so that the paper reel 68 rotates to transfer the paper upward along the flat plate 67. At this time, the paper reel 68 on the flat plate 67 and the paper reel 68 connected to the printing end shell 1 position the paper, and the flat plate 67 is allowed to slide upward along the slide bar fixing plate 64 through the connected vertical slide bar 65 through the outer spring of the vertical slide bar 65, so that the flat plate 67 is close to the paper pressing paper on the bottom side of the printing end shell 1, so that the paper remains flat;

[0036] When the print head 9 moves, the print head 9 will drive the linkage rod 73 to move, so that the linkage rod 73 will fit with the arc wave block 74. When the linkage rod 73 moves to the lowest point of the arc wave block 74, the slide groove bar 71 will be lifted upward. When the linkage rod 73 moves to the highest point of the arc wave block 74, the slide groove bar 71 will move downward along the vertical slide bar 65. The up and down movement of the slide groove bar 71 will drive the external heating tube installed on the bottom surface to move up and down.
