Ribbon cartridge, label printer and installation method

Abstract

The invention provides a ribbon cartridge, a label printer and an installation method. The ribbon cartridge comprises a shell, the shell is provided with a printing head clamping groove, a side wall and a positioning through hole located in the inner side of the side wall. A ribbon cutting part is formed at the joint of the side wall and the printing head clamping groove; a first clamping accommodating part, a second clamping accommodating part and a third clamping accommodating part are arranged on the surface of the shell; the first clamping accommodating part, the second clamping accommodating part and the third clamping accommodating part correspond to a first positioning column, a second positioning column and a third positioning column of the label printer respectively; and central phantom lines of the first clamping accommodating part, the second clamping accommodating part and the positioning through hole form a triangular area. The label printer comprises the ribbon cartridge.The method is applied to the label printer and the ribbon cartridge. According to the ribbon cartridge, the label printer and the installation method, the ribbon cartridge can be accurately and smoothly assembled on a cartridge assembling part, stable positioning of the ribbon cartridge can be ensured, accurate and complete cutting of a cutter can be ensured, the product size can be reduced, theinternal capacity can be increased, and the appearance smoothness can be improved.

Description

technical field [0001] The invention relates to the technical field of label ribbon cassettes, in particular to an easily clamped and positioned ribbon cassette, a label printer and a method for installing the ribbon cassette. Background technique [0002] The existing ribbon cassette has the problem that the ribbon cassette is tilted and cannot be disassembled smoothly due to the improper setting of the structural position with the guiding function, positioning function and clamping function. And, if the parts and positioning holes for clamping the tape cassette are not arranged in a good balance, the assembly force and the pulling force will be unbalanced, which will also cause the tape cassette to tilt and cause jamming, so that it cannot be smoothly disassembled. [0003] During the printing process, due to the lack of a good balance in the configuration of the fastening parts of the tape cassette and the positioning holes and guide holes, the ribbon cassette will loosen...

AI Technical Summary

Problems solved by technology

[0002] Due to the improper setting of the structural position of the existing ribbon cassette with guiding, positioning, and clamping functions, there is a problem that the ribbon cassette is tilted and cannot be disassembled smoothly

In addition, if the parts and positioning holes for clamping the tape cassette are not arranged in a good balance, the assembly force and the pulling force will be unbalanced, which will also cause the tape cassette to tilt and cause jamming, making it impossible to disassemble smoothly.

[0003] During the printing process, due to the lack of a good balance to configure the clamping parts of the tape cassette and the positioning holes and guide holes, the ribbon cassette will loosen during the printing process, and the cutter cannot cut smoothly, which will affect the printing quality.

[0004] In addition, the guide holes or clamping parts of the existing ribbon cassettes are generally arranged on the outer peripheral surface of the ribbon cassette, which will increase the overall volume of the product to a certain extent, or affect the smoothness of the appearance of the ribbon cassette
