Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a napkin printing device that is easy to replace the pressing roller, including a work surface 1, a smoothing roller 2, an auxiliary roller 3, a conveyor belt 4, a dust cover 5, a hydraulic support rod 6, a mounting cover 7, a fixing plate 8, an embossing roller 9, an ink box 10, a hose 11, a motor 12, a reverse screw rod 13, a receiving box 14, an overflow hole 15, an electric telescopic rod 16, a punching pressing plate 17 and a winding roller 18, such as Figure 1 and Figure 3 As shown, a support rod is installed at the left end of the upper surface of the work surface 1, and a motor is installed at the rear side of the support rod. The output end of the motor is connected to a smoothing roller 2, and an auxiliary roller 3 is rotatably installed below the smoothing roller 2. The napkin paper to be printed passes between the smoothing roller 2 and the auxiliary roller 3, and the motor is turned on. The motor drives the smoothing roller 2 to rotate, so that the napkin paper can be smoothed, and the auxiliary roller 3 assists in conveying the napkin paper;

[0023] A conveyor belt 4 is installed inside the upper surface of the work surface 1. The smoothing roller 2 and the auxiliary roller 3 convey the napkins to the conveyor belt 4. When the conveyor belt 4 is turned on, the smoothing roller 2, the auxiliary roller 3 and the conveyor belt 4 drive the napkins to continue to move to the right. A dust cover 5 is installed on the upper surface of the work surface 1, and the dust cover 5 plays a certain dust-proof role.

The pump and the control valve are turned on to transport the ink in the ink cartridge 10 to the embossing roller 9 through the hose 11. The control valve is convenient for controlling the amount of ink to be discharged to prevent excessive ink from contaminating the napkin paper. After the ink enters the embossing roller 9, micropores are opened on the lower surface of the embossing roller 9 to compress and print the napkin paper.

[0027] After embossing is completed, the hydraulic support rod 6 drives the embossing roller 9 back to the installation cover 7, and the motor 12 drives the reverse screw rod 13 to rotate in the reverse direction, thereby driving the receiving box 14 to close the installation cover 7. The receiving box 14 plays the role of receiving ink. When excess ink drips from the embossing roller 9, an overflow hole 15 is opened on the surface of the receiving box 14, and the ink enters the receiving box 14 through the overflow hole 15. The rear side of the receiving box 14 is connected with a suction tube to facilitate ink recovery and prevent excess ink from dripping and contaminating the napkin paper;

[0028] The conveyor belt 4 continues to transport the napkins, and an electric telescopic rod 16 is installed at the top of the dust cover 5. A perforated pressing plate 17 is installed at the lower end of the electric telescopic rod 16. The conveyor belt 4 drives the napkins to move to a suitable position, and the electric telescopic rod 16 is turned on. The electric telescopic rod 16 drives the perforated pressing plate 17 to descend, and the perforated pressing plate 17 presses and breaks the napkins at intervals to facilitate subsequent pulling and use.
