Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a printer paper feeding clutch. Background Art

[0002] The printer paper feed clutch is a device used to move paper. When the printer is ready to print, the paper feed clutch pressure plate will apply downward pressure to make the gears in the paper feed clutch contact with the paper. The gears in the paper feed clutch rotate and the friction with the paper pulls the paper out of the paper box, thereby improving the paper transportation efficiency.

[0003] The existing paper feed clutch controls the electromagnetic clutch to be energized through a relay, so that the electromagnet generates magnetic force, drives the clutch pressure plate to rotate, limits the paper, and prevents the clutch pressure plate from rotating excessively through a baffle, which affects the paper movement efficiency, and transports the paper through a gear set.

[0004] However, in the implementation of relevant technologies, it was found that the existing paper feed clutch has the following problems: the clutch pressure plate collides with the baffle when rotating, which increases the noise when the printer is working, accelerates the wear rate of the clutch pressure plate, reduces the service life of the paper feed clutch, and thus reduces the service life of the printer. In view of this, a printer paper feed clutch is provided to overcome the above-mentioned defects. Utility Model Content
