The movable side 12 is formed to extend obliquely in the direction of the hinge side 11 from the end connected to the outer side surface 13 to the end connected to the inner side surface 14. As shown in fig. 2, the slope design of the movable side 12 can guide the printing paper when the printing paper is discharged through the paper outlet 4.

Note that, in the present embodiment, as shown in fig. 1, the paper feed unit 2 includes: a first bracket 21, a second bracket 22, a thermo-sensitive rubber roller 23 and a driving element 24. The first support 21 and the second support 22 are oppositely disposed on the inner side 14 of the main body 1 of the flip 5 along a direction parallel to the movable side 12. Meanwhile, as shown in fig. 2, the thermo-sensitive adhesive roller 23 includes: the rubber roller body 231, the first protruding shaft 232 formed by one end of the rubber roller body 231 protruding outwards along the axis direction of the rubber roller body 231, and the second protruding shaft 233 formed by the other end of the rubber roller body 231 protruding outwards along the axis direction of the rubber roller body 231, wherein the first protruding shaft 232 is rotatably connected with the first support 21, and the second protruding shaft 233 is rotatably connected with the second support 22. Meanwhile, the driving element 24 is disposed on the first bracket 21 and connected to the first protruding shaft 232, so that the driving element 24 can drive the rubber roller body 231 to rotate through the first protruding shaft 232. Of course, in practical applications, the driving element 24 may also be disposed on the second bracket 22 and connected to the second protruding shaft 233, so that the driving element 24 can also drive the rubber roller body 231 through the second protruding shaft 233. In addition, the driving element 24 used in the present embodiment may be a motor, and an output shaft of the motor is directly fixedly connected to the first protruding shaft 232 or the second protruding shaft 233 through a coupling, so that the rotation of the thermo-rubber roller 23 can be realized.

In addition, as a preferable scheme, the outer side surface of the rubber roller body 231 adopted in the embodiment is a rough surface, so that when the rubber roller body 231 conveys printing paper, the friction force between the rubber roller body 231 and the printing paper can be improved, and the printing paper can be conveyed more easily.

A second embodiment of the present invention relates to a thermal printer, as shown in fig. 4 and 5, including: a housing 3, a printer core 5, a paper clamping mechanism 6 and a flip mechanism as described in the first embodiment.

As shown in fig. 4, the housing 3 includes: the front panel 32, the back panel 32, the first side plate 33 and the second side plate 34 are arranged on the bottom plate 35. The front panel 31 and the rear panel 32 are disposed in parallel and opposite to the bottom panel 35 along the length direction of the bottom panel 35, and the first side panel 33 and the second side panel 34 are disposed in parallel and opposite to each other along the width direction of the bottom panel 35. In practical applications, the hinge side 1 of the flip body 1 of the flip mechanism may be hinged to the first side plate 33 and the second side plate 34, respectively.

The support plate 53 can improve the support performance of the guide side plate 52, and prevent the guide side plate 52 from deforming, so that the guide side plate 52 has better guide performance for the paper.

In addition, it should be noted that in the present embodiment, as shown in fig. 5, a side of the front panel 31 away from the bottom panel 35 is a slope 311. The inclined surface 311 extends in a direction away from the bottom plate 35 gradually from the side of the front panel 31 opposite to the rear panel 32 to the side away from the rear panel 32. Therefore, as can be seen from the above, the inclined surface 311 can cooperate with the inclined surface design of the movable side 12 of the flip body 1 to guide the printing paper in the process of being sent out of the paper outlet 4, so that the printing paper can be more easily conveyed.

Also, as shown in fig. 5, preferably, when the flip body 1 is flipped to the limit position in the direction of the rear panel 32, the paper output opening 4 formed between the movable side 12 of the flip body 1 and the front panel 31 is right on the conveying path of the paper feeding assembly 2, so that the printing paper fed by the paper feeding assembly 2 can directly enter the paper output opening 4, thereby further improving the conveying performance of the printing paper.

It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
