Description

Technical Field

[0001] The utility model belongs to the technical field of printers, and in particular relates to a printer toner cartridge. 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: print resolution, print speed and noise. There are many types of printers. According to whether the printing element has an impact action on the paper, they are divided into impact printers and non-impact printers. According to the printing character structure, they are divided into full-width printers and dot matrix printers. According to the way a line of words is formed on the paper, they are divided into serial printers and line printers. According to the technology used, they are divided into cylindrical printers, spherical printers, inkjet printers, thermal printers, laser printers, electrostatic printers, magnetic printers, light-emitting diode printers and other printers. Among them, the toner cartridge is an important structure of the printer. The PU sheet on the existing toner cartridge is mostly glued to the pressure plate by glue, which requires the pressure plate to have a larger volume, resulting in an increase in the cost of the existing toner cartridge during the production process, so it needs to be improved.

[0020] For example 1, please refer to Figure 1-3The utility model provides a printer toner cartridge, comprising a box body 1 and two fixed shells 2, the two fixed shells 2 are symmetrically arranged on the box body 1, and the two box bodies 1 are respectively located at both ends of the box body 1, a pressing plate 3 is arranged between the two fixed shells 2, the pressing plate 3 is located above the box body 1, and a PU sheet 4 is further arranged between the two fixed shells 2, the PU sheet 4 is located between the box body 1 and the pressing plate 3, and the box body 1 and the pressing plate 3 clamp the PU sheet 4, place the PU sheet 4 at a predetermined position on the box body 1, and then install the pressing plate 3 on the box body 1, so that the pressing plate 3 can clamp and fix the PU sheet 4 on the box body 1, avoiding the use of glue to fix the PU sheet 4. The PU sheet 4 is fixed on the pressure plate 3 to facilitate subsequent replacement, reduce the volume required for the pressure plate 3 to bond the PU sheet 4, and reduce manufacturing costs. The pressure plate 3 is movably arranged on the box body 1, and the pressure plate 3 is fixed to the box body 1 by screws. The pressure plate 3 is fixed to the box body 1 by screws, which facilitates the installation and disassembly of the box body 1, and thus facilitates the maintenance of the pressure plate 3 and the PU sheet 4. Conductive blocks 6 are provided on the two fixed shells 2, and the two ends of the pressure plate 3 are electrically connected to the two conductive blocks 6 respectively. After the pressure plate 3 is installed on the box body 1, the pressure plate 3 can be electrically connected to the conductive blocks 6, which facilitates the connection of the pressure plate 3 to the power supply.
