[0001] The utility model relates to the technical field of printer equipment, in particular to a wear-resistant printer shaft. Background Art

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on relevant media. There are three indicators to measure the quality of a printer: printing resolution, printing speed and noise. There are many types of printers. According to whether the printing element has an impact action on the paper, it is divided into impact printers and non-impact printers. According to the structure of printed characters, it is divided into full-width character printers and dot matrix character printers. According to the way a line of characters is formed on the paper, it is divided into serial printers and line printers. According to the technology used, it is divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers. Printers are generally provided with a printer shaft, which is used to press the paper and transport the paper. However, the existing printer shaft has poor wear resistance and is prone to severe wear, which affects its normal transportation of paper and reduces the service life of the printer.

At the same time, the wear-resistant sleeve can withstand a certain pressure and wear, ensuring the normal operation of the printer and extending its service life. The wear-resistant pad is installed on the outer layer inside the wear-resistant sleeve to improve the wear resistance of the wear-resistant sleeve. The wear-resistant pad avoids the need for frequent replacement of the wear-resistant sleeve by the staff during use. Therefore, the wear-resistant pad improves the usability of the wear-resistant sleeve, and also strengthens the protection of the shaft body, thereby achieving a double-layer protection effect.

[0009] 2. For the wear-resistant printer shaft, when the wear-resistant sleeve is damaged during long-term use, the staff will pull out the pin from the first connecting plate and the second connecting plate, and move the fixed sleeve by pulling out the pin, and the block is moved out of the slot by disengaging the fixed sleeve. At this time, the staff can remove the wear-resistant sleeve installed on the outer wall of the shaft body, and then install a new wear-resistant sleeve on the outer wall of the shaft body. Through the installation of the wear-resistant sleeve, the staff will re-fix the fixed sleeve to the side of the shaft body, and when the fixed sleeve and the wear-resistant sleeve move to a certain distance, the block is inserted into the slot, and the fixed sleeve is fixed to the side of the wear-resistant sleeve by the insertion of the block. At the same time, the staff will insert the pin into the first connecting plate and the second connecting plate to fix the wear-resistant sleeve, which is convenient for replacing the wear-resistant sleeve.
