Description

Technical Field

[0001] The utility model relates to the technical field of ink cartridges, in particular to a stirring frame fixing mechanism. Background Art

[0002] A printer is a device used to convert electronic documents or images into paper output. It uses printing technology to convert digital information into a visual form so that people can view and save the information on paper. The ink cartridge is a device used to store toner.

[0003] When toner is used as the printing material, a stirring frame is installed inside the ink cartridge. When the stirring frame rotates inside the ink cartridge, the toner inside the ink cartridge can be stirred to ensure the activity of the toner inside the ink cartridge, thereby facilitating the output of the toner inside the ink cartridge and printing it on paper.

[0004] When the stirring frame is installed inside the ink cartridge, one end of the stirring frame is usually engaged with the driving shaft that drives the stirring frame to rotate, and the other end of the stirring frame is sleeved inside the sleeve inside the ink cartridge shell through a shaft. However, as the stirring frame rotates, toner will enter between the shaft and the sleeve. The toner is usually made of carbon powder material. As the shaft and the sleeve rotate and rub, the temperature of the carbon powder between the shaft and the sleeve will increase, and the heated carbon powder will agglomerate, which will cause the resistance between the shaft and the sleeve to increase, thereby increasing the torque force on the stirring frame, and even causing the stirring frame to be stuck and damaged, making it inconvenient to discharge the toner that has entered the shaft end of the stirring frame.
