In the description of the present invention, if "a plurality" is referred to, it means one or more, if "a plurality" is referred to, it means two or more, if "more than", "less than" or "more than" is referred to, it is understood that the number is not included, and if "more than", "less than" or "within" is referred to, it is understood that the number is included. If reference is made to "first" or "second", this should be understood to distinguish between features and not to indicate or imply relative importance or to implicitly indicate the number of indicated features or to implicitly indicate the precedence of the indicated features.

In addition, unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1, which shows an overall schematic diagram of the paper box assembly in an embodiment of the present invention, the paper box assembly is composed of a paper box 12 and a base 11 for carrying the paper box 12, the base 11 is detachably connected to the paper box 12, and the paper in the paper box 12 rotates relative to the base 11 and leaves from the paper outlet after printing is completed through a printing area of the printer.

Referring to fig. 2, which shows an explosion diagram of the paper box assembly according to an embodiment of the present invention, the base 11 is recessed inwards to form a cavity 111, the cavity 111 is used to accommodate the paper box 12, and the side wall around the cavity 111 is an arc surface, when the paper tube on the paper box 12 rotates to output paper, the printing paper on the paper tube and the side wall surrounding the cavity 111 form an arc paper feeding channel, the printing paper moves stably in the channel, and the paper tube may be a cylindrical structure formed by paper rolls completely or a cylindrical structure formed by rolling paper externally.

In addition, a Y-shaped groove 112 is provided on the end wall surrounding the cavity 111, and the opening of the Y-shaped groove 112 faces the outside of the cavity 111 (i.e., the paper cartridge is loaded from the opening of the Y-shaped groove 112), and the specific function of the Y-shaped groove 112 will be described later.

Referring to fig. 3, there is shown an exploded view of the paper box in one embodiment of the present invention, and as shown, the paper box is composed of a paper tube 121, a paper shaft 122 and a cover plate 123. The paper tube 121 is formed by winding printing paper, and the rotation of the paper tube 121 on the paper shaft 122 corresponds to the process of feeding the paper tube 121 to the printer.

The cover plates 123 are respectively disposed at both ends of the paper shaft 122 in pairs, and the distance between the two cover plates 123 corresponds to the width of the printing paper in the paper cylinder 121.

Referring to fig. 4, which shows an installation diagram of the paper shaft and the cover plate in an embodiment of the present invention, a protruding rib 1221 is disposed on a side wall of the paper shaft 122, a protrusion 1222 extends from both ends of the paper shaft 122, the protrusion 1222 is matched with the Y-shaped groove 112 in fig. 2, the protrusion 1222 is clamped into the Y-shaped groove 112, and the engagement of the protrusion 1222 and the Y-shaped groove 112 under the action of gravity fixes the paper shaft 122 in the Y-shaped groove 112.

The paper shaft 122 penetrates through the central hole 1231 of the cover plate 123, and the convex rib 1221 on the paper shaft abuts against the groove on the side wall of the central hole 1231, so that the cover plate 123 and the paper shaft 122 are relatively fixed.

The cross section of the paper shaft 122 is enclosed by an arc segment and a straight segment, the distance from the arc segment to the axis is larger than the distance from the straight segment to the axis, and the straight segment is used for preventing the cover plate 123 from rotating relative to the paper shaft 122.

In summary, since the distance between the two cover plates 123 corresponds to the width of the paper in the paper tube 121, as long as the length of the paper shaft 122 is the same and the protrusion 1222 on the paper shaft 122 is engaged in the Y-shaped slot 112, by replacing the paper cassette 12 with different spacing between the two cover plates 123, printing paper with different widths can be supplied without changing the printer (corresponding to the base 11 in the present application).

Further, the rib 1221 can be made of rubber materials, so that the rib 1221 and the central hole 1231 are maintained in a tight abutting state, and the relative rest of the rib 1221 and the central hole 1231 is guaranteed.

While the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the embodiments, and those skilled in the art can make various equivalent modifications and substitutions without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
