[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0031] like Figure 1-4 As shown, as a first aspect of the present application, this embodiment 1 proposes a portable printer based on an anti-paper jam structure, and the portable printer based on the anti-paper jam structure includes: a box body 1, a paper bin 2, a paper outlet channel 3, a printing component 4, a paper outlet component 5, a first guide shaft 6 and a second guide shaft 7;
[0032] Wherein, the box body 1 includes a accommodating cavity, and the side wall of the box body 1 is provided with an opening, and the opening is connected to the accommodating cavity; the paper bin 2 is arranged in the accommodating cavity, and the paper bin 2 includes a loading port, and the setting direction of the loading port coincides with the setting direction of the opening; one end of the paper output channel 3 is connected to the paper bin 2, and the other end of the paper output channel 3 is connected to the outside of the box body 1; the printing component 4 and the paper output component 5 are arranged opposite to each other along the two sides of the paper output channel 3; the first guide shaft 6 and the second guide shaft 7 are arranged on the paper output channel 3, and are arranged at intervals along the extension direction of the paper output channel 3, and the outer surfaces of the first guide shaft 6 and the second guide shaft 7 are tangent to the extension direction of the paper output channel 3.
[0033] Specifically, by arranging the first guide shaft 6 and the second guide shaft 7 on the paper output channel 3, and the first guide shaft 6 and the second guide shaft 7 are arranged at intervals along the extension direction of the paper output channel 3, and the outer surfaces of the first guide shaft 6 and the second guide shaft 7 are tangent to the extension direction of the paper output channel 3, when the paper passes through the first guide shaft 6 and the second guide shaft 7 in sequence, the paper is constrained by the offset gap between the first guide shaft 6 and the second guide shaft 7, thereby preventing the paper from returning to the paper bin 2 and causing paper jam.
[0034] For the paper bin 2, the distance between the structural edge of the outer periphery of the paper bin 2 and the edge of the paper bin 2 is designed to be 1-1.5 mm.
[0035] Furthermore, the first guide shaft 6 and the second guide shaft 7 are both round shafts, so that when the printing paper passes through the first guide shaft 6 and the second guide shaft 7, the friction between the printing paper and the outer surface of the first guide shaft 6 and the second guide shaft 7 is reduced.
[0036] Further, the first guide shaft 6 is rotatably disposed on the paper outlet passage 3, and the second guide shaft 7 is fixedly disposed on the paper outlet passage 3, or the first guide shaft 6 is fixedly disposed on the paper outlet passage 3, and the second guide shaft 7 is rotatably disposed on the paper outlet passage 3.
[0037] Furthermore, the center point of the paper bin 2 faces the loading port, and when a printing paper roll needs to be loaded, the printing paper roll can be placed in the paper bin 2 through the loading port, and the center of the paper roll faces the center point of the paper bin 2; the portable printer also includes a tray assembly 8, which is arranged at the center point of the paper bin 2 and can rotate freely relative to the paper bin 2. In this way, the placed paper roll can be supported by the tray, and when the printing paper roll is discharged, the tray assembly 8 rotates synchronously.
[0038] Furthermore, the tray assembly 8 includes: a main body 801 and a vertical shaft 802 , wherein the main body 801 is rotatably connected to the center point of the paper bin 2 ; and the vertical shaft 802 is vertically arranged at the axis of the main body 801 .
[0039] It should be noted that a hollow plastic shaft is provided in the center of the paper roll for the printing paper (continuous paper) to be rolled up around the shaft; when placing the paper roll, the hollow plastic shaft can be inserted into the vertical shaft 802 to fix the position of the printing paper roll, and the main body 801 plays a supporting role for the printing paper roll.
[0040] Furthermore, the edges of the loading port of the paper bin 2 are provided with arc chamfers, so that the printing paper roll will not be scratched against the edges of the loading port when the printing paper roll is placed.
