[0023] In one embodiment of the utility model, the top end face of the frame 1 is fixedly connected to a hydraulic cylinder 4, the bottom end face of the hydraulic cylinder 4 is fixedly connected to a mounting frame 5, the inner wall of the mounting frame 5 is rotatably connected to an ink distribution roller 6, the top end face of the mounting frame 5 is fixedly connected to an ink storage cylinder 8, the ink storage cylinder 8 is located directly above the ink distribution roller 6, the ink storage cylinder 8 drips printing ink onto the ink distribution roller 6, the side wall of the mounting frame 5 is fixedly connected to a motor 2 9, the output shaft of the motor 2 9 is fixedly connected to the printing roller 7, the ink distribution roller 6 contacts the side wall of the printing roller 7, the rotation of the printing roller 7 drives the ink distribution roller 6 to rotate through the belt 10, and then transfers the ink to the surface of the printing roller 7, the transmission shaft of the ink distribution roller 6 is transmission connected to the belt 10, the belt 10 is transmission connected to the transmission shaft of the printing roller 7, the mounting frame The side wall of the mounting frame 5 is fixedly connected with a bracket 11, and the end of the bracket 11 away from the mounting frame 5 is fixedly connected with a collecting bucket 12. The collecting bucket 12 is divided into an upper inclined plate and a lower inclined plate. The upper inclined plate contacts the surface of the printing roller 7. The upper inclined plate scrapes off the ink remaining after printing by the printing roller 7 to improve the uniformity of printing. The side wall of the collecting bucket 12 is fixedly connected with an arc portion 13, and the inner wall of the arc portion 13 is fixedly connected with a check bar 14. The side wall of the collecting bucket 12 is fixedly connected with a guide groove 15, and the guide groove 15 guides the residual ink collected by the collecting bucket 12 to reduce the accumulation of residual ink. The side of the mounting frame 5 away from the collecting bucket 12 is fixedly connected with an arc telescopic rod 16, and the end of the arc telescopic rod 16 away from the mounting frame 5 is fixedly connected to the collecting bucket 2 17.

[0024] The rotation of motor 1 2 drives the conveyor belt 3 to move, and then the decorative paper passes under the printing roller 7. The hydraulic cylinder 4 is started to push the printing roller 7 to contact the decorative paper. The motor 2 9 is started to drive the printing roller 7 to rotate. The direction of rotation of the printing roller 7 is consistent with the direction of movement of the conveyor belt 3. The relative speed between the surface of the printing roller 7 and the decorative paper is small. The relatively small speed difference reduces the generation of friction, thereby reducing the risk of damage to the surface of the printing roller 7, thereby improving the service life and printing effect of the printing roller 7. When the printing roller 7 rotates to print the decorative paper, the upper inclined plate scrapes off the ink remaining after the printing roller 7 prints. In the process of scraping ink, the ink will move to both sides of the upper inclined plate. When the ink moves to both sides of the upper inclined plate, it is guided to the lower inclined plate by the arc portion 13, and the check strip 14 can prevent the reverse movement of the ink, causing the ink to drip or be re-adhered to the printing roller 7. By scraping off the excess ink and re-inking it through the ink distribution roller 6, the uniformity of the printing of the device paper by the printing roller 7 is improved, thereby improving the quality of the printed product.

[0025] In addition, an arc-shaped telescopic rod 16 is fixedly connected to the side of the mounting frame 5 away from the collecting bucket 12, and one end of the arc-shaped telescopic rod 16 away from the mounting frame 5 is fixedly connected to the collecting bucket 2 17. When the ink uniforming roller 6 and the printing roller 7 rotate, the ink may be uncontrollably thrown off from the ink uniforming roller 6 and the printing roller 7. This part of the thrown ink is collected by the collecting bucket 2 17. When the ink in the collecting bucket 2 17 is collected to a certain extent, the arc-shaped telescopic rod 16 is contracted by lifting the collecting bucket 2 17 upwards, and the ink in the collecting bucket 2 17 can be cleaned at this time.

[0026] In the utility model, when in use, the decorative paper is carried by the conveyor belt 3 and passes under the printing roller 7. The printing roller 7 contacts the decorative paper, and the ink storage cylinder 8 drips the printing ink onto the ink distribution roller 6. The motor 2 9 drives the printing roller 7 to rotate. The rotation of the printing roller 7 drives the ink distribution roller 6 to rotate through the belt 10, and then the ink is transferred to the surface of the printing roller 7. The direction of rotation of the printing roller 7 is consistent with the direction of movement of the conveyor belt 3. The decorative paper is printed, and the upper inclined plate scrapes off the ink remaining on the surface of the printing roller 7, so that the printing roller 7 can be re-inked through the ink distribution roller 6. Furthermore, when the ink distribution roller 6 and the printing roller 7 rotate, the ink may be uncontrollably thrown off from the ink distribution roller 6 and the printing roller 7. This part of the thrown ink is collected by the collecting bucket 2 17.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
