Abstract

The invention provides a paper roll fixing device of a printer. The paper roll fixing device of the printer comprises a first supporting base and a second supporting base, wherein the first supporting base comprises a first supporting protruding portion and a plurality of first idler wheels, and the second supporting base comprises a second supporting protruding portion and a plurality of second idler wheels. The first supporting protruding portion and the second supporting protruding portion extend into the two ends of a hollow roll center of a paper roll respectively so that the paper roll can be fixedly arranged between the first supporting base and the second supporting base, and can be supported by the first idler wheels and the second idler wheels. The paper roll fixing device of the printer can be applicable to paper rolls with hollow roll centers with different diameters.

Description

technical field [0001] The invention relates to a paper roll fixing device, in particular to a paper roll fixing device applied to a printer. Background technique [0002] There are many printers on the market that use roll paper as the output medium, such as label printers. The paper roll used by the label printer is composed of a hollow shaft and a paper tape wound on the hollow shaft. The paper tape includes a long strip of film and label paper attached to it at intervals. During the printing process, the paper tape is driven to make the label paper pass through the printing mechanism, so the printing mechanism prints on the label paper. During the printing process, the label paper is continuously output from the label printer, and the paper roll rotates accordingly and the overall diameter gradually decreases. Therefore, a fixed structure or support structure needs to be set inside the label printer to prevent the paper roll from bouncing up and down, shifting left and...
