[0023] During use, the staff first feeds the paper to be printed between the two conveying rollers 4, rotates and flattens the paper, and then conveys it to the conveyor belt 5 for conveying. At this time, the two deviation correction wheels 12 respectively limit the left and right sides of the paper to correct the deviation, so that the paper is in the middle during conveying to prevent deviation. Then the first electric push rod 6 is started to allow the printing body 7 to move up and down to print the paper; the driving motor 9 is started to rotate the conveying wheel 10, and the outer wall of the conveying wheel 10 contacts the surface of the paper, which is conducive to increasing the paper feeding speed and thus improving the overall printing efficiency. It is conducive to printing the paper, and at the same time, during the paper conveying, it is conducive to limiting the deviation of the paper, which is conducive to preventing the paper position from deviating, so that the paper is in the correct printing position, thereby improving the quality and accuracy of the printed product.

[0024] like Figure 1-Figure 4 As shown, movable holes 13 are respectively opened on the left and right sides of the inner wall of the first U-shaped frame 2, and second electric push rods 14 are respectively fixed on the left and right sides of the outer wall of the first U-shaped frame 2. One ends of the telescopic rods of the two second electric push rods 14 are respectively slidably inserted into the two movable holes 13, and one ends of the telescopic rods of the two second electric push rods 14 are respectively fixedly connected to the outer sides of the two first U-shaped plates 11.

[0025] During use, the staff can start the two second electric push rods 14 to move the two first U-shaped plates 11 and the two correcting wheels 12 closer to or farther away from each other, thereby facilitating the adjustment of the distance between the two correcting wheels 12, thereby facilitating the correction of papers of different sizes and improving the practicality of the device.

[0026] like Figure 1-Figure 4As shown, a limiting hole 15 is provided on the top surface of the first U-shaped frame 2, and a limiting column 16 is slidably inserted inside the limiting hole 15, and the bottom end of the limiting column 16 is fixedly connected to the top surface of the printing body 7, and a rotating hole 17 is provided on the inner top and bottom surfaces of the two first U-shaped plates 11 respectively, and a mounting groove 18 is provided on the top and bottom ends of the two deviation correcting wheels 12 respectively, and a rotating column 19 is slidably inserted inside the two mounting grooves 18 respectively, and the two rotating columns 19 are rotatably arranged in the two rotating holes 17 respectively, and the inner walls of the two mounting grooves 18 are fixed with springs 20 respectively, and the outer ends of the two springs 20 are fixedly connected to the inner ends of the two rotating columns 19 respectively.

When the staff needs to install the deflection correction wheel 12, they first squeeze the two rotating columns 19 so that the two rotating columns 19 are close to each other and enter the two installation grooves 18 respectively. At this time, the two springs 20 are in a compressed state, and then the deflection correction wheel 12 is placed in the first U-shaped plate 11, so that the two rotating columns 19 correspond to the two rotating holes 17 respectively. The two springs 20 are used to automatically reset the two rotating columns 19, so that the two rotating columns 19 are respectively slidably inserted in the two rotating holes 17, and the installation of the deflection correction wheel 12 is completed; on the contrary, when the staff needs to disassemble the deflection correction wheel 12, they squeeze the two rotating columns 19 so that the two rotating columns 19 are respectively moved into the two installation grooves 18, and the deflection correction wheel 12 can be taken out from the first U-shaped plate 11, which is convenient for the staff to disassemble and assemble the deflection correction wheel 12, so as to facilitate cleaning or replacement.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the outer walls of the two conveying rollers 4 are respectively provided with an electrostatic adsorption layer 21 , a second U-shaped plate 22 is fixed to the top surface of the U-shaped seat 1 , and a heating plate 23 is fixed to the inner top surface of the second U-shaped plate 22 .

[0029] During use, the electrostatic adsorption layer 21 helps to adsorb dust on the surface of the paper onto the conveying roller 4, which helps to reduce the impact of dust on the printing quality, thereby helping to improve the printing quality of the paper. The heating sheet 23 helps to dry the printed paper, which can speed up the drying speed of the paper, thereby improving production efficiency, and at the same time helps to fix the ink and prevent the problem of blurring caused by the ink not drying, thereby ensuring the printing quality.
