Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] During long-term use, the current traditional label printers are prone to misalignment of the moving path of thermal roll paper during printing due to the unreasonable design of the internal structure of the printer, which often leads to paper jams, which not only affects work efficiency but also increases maintenance costs. In response to these problems, this embodiment proposes a new label printer paper jam solution. By optimizing the printer structure design, paper jams are effectively reduced, ensuring that the printer can work stably in various environments, thereby improving the durability and ease of use of the printer, and providing users with a more convenient and efficient printing experience.

[0037] Please refer to Figure 1-5 As shown, this embodiment provides a label printer 100, which includes: a housing 110, a paper bin 111, a rubber roller 113, a flip cover assembly 114 and a thermal print head 115; wherein the paper bin 111 is installed on the housing 110, and the paper bin 111 is used to load a thermal paper roll 112; the rubber roller 113 is installed on the housing 110, and the rubber roller 113 is used to drive the thermal paper roll 112 to move out of the paper bin 111; the flip cover assembly 114 is movably installed on the housing 110; the thermal print head 115 is installed on the flip cover assembly 114; wherein the flip cover assembly 114 is movably and detachably buckled on the paper bin 111, and the thermal print head 115 presses the thermal paper roll 112 and adheres to the rubber roller 113 when the flip cover assembly 114 is buckled and connected to both sides of the paper bin 111, so that the thermal paper roll 112 pushed by the rotation of the rubber roller 113 passes through the thermal print head 115 for printing.

[0038] According to the above solution, optionally, the flip cover assembly 114 is used to cover or open the housing 110 , and the thermal print head 115 is installed on the flip cover assembly 114 to print on the passing thermal roll paper 112 .

[0039] According to the above scheme, it can be understood that in this embodiment, the flap assembly 114 is detachably fastened to the paper bin 111, and the thermal print head 115 presses the thermal paper roll 112 and adheres to the rubber roller 113 when the flap assembly 114 is fastened to the paper bin 111, so that the thermal paper roll 112 in the paper bin 111 can be clamped and printed between the rubber roller 113 and the thermal print head 115 when it is driven to move outward by the rotation of the rubber roller 113 and is printed, thereby avoiding the gap between the thermal print head 115 and the rubber roller 113 causing the thermal paper roll 112 to be misaligned in the moving path during the moving process, ensuring the stable and orderly movement of the thermal paper roll 112, effectively preventing paper jams, and being applicable to paper rolls of different types and materials, thereby improving the working efficiency and practicality of the label printer 100 and reducing maintenance costs.

[0040] Preferably, the flip cover assembly 114 includes an upper cover body 121 and a lower cover body 122, and the lower cover body 122 is provided with an embedding groove 12a for embedding the thermal print head 115, and a printing opening is provided at the bottom end of the embedding groove 12a, so that the thermal print head 115 can print on the thermal paper roll 112 located on the rubber roller 113 through the printing opening; it can be understood that the printing opening is adapted to the area of ​​the side of the thermal print head 115 facing the thermal paper roll 112 for printing, so that the part of the thermal print head 115 that prints the thermal paper roll 112 is completely extended out of the embedding groove 12a, which is beneficial to improving the printing effect.

[0041] Preferably, the width L1 of the paper bin 111 is the same as the width L2 of the rubber roller 113, and the width L3 of the thermal paper roll 112 is between 2 / 3 and 4 / 5 of the width of the paper bin 111; optionally, in this embodiment, the width L3 of the thermal paper roll 112 is 4 / 5 of the width of the paper bin 111. It can be understood that this structure allows the flip cover assembly 114 to be connected to both sides of the paper bin 111 when it is snap-fitted to the paper bin 111, and allows the thermal paper roll 112 moved out of the paper bin 111 to fit with the rubber roller 113 so that it can be driven by the rubber roller 113, thereby avoiding the width L1 of the paper bin 111 being too wide, which may cause the thermal paper roll 112 to be misaligned when it is moved out of the paper bin 111.

[0042] Preferably, the label printer 100 also includes a rotating bin 131, and the rubber roller 113 is installed in the rotating bin 131; further, the label printer 100 also includes a driving motor 132 and a control mainboard 133 installed in the housing 110, the driving motor 132 is electrically connected to the rubber roller 113, and the control mainboard 133 is used to control the driving motor 132 to drive the rubber roller 113 to rotate in the rotating bin 131; it can be understood that the benefit of setting the rotating bin 131 is that it can protect the rubber roller 113 and prevent the rubber roller 113 from being hit by other components due to the fact that it is not protected during the use of the printer. The thermal paper roll 112 or the rubber roller 113 thereon can be easily displaced to prevent damage or wear thereof and other situations such as damage to the paper roll; further, when the flip cover assembly 114 is snapped and connected to the shell body 110, the lower cover body 122 seals the paper bin 111 and forms a paper outlet 13a with the paper bin 111. The thermal paper roll 112 is driven by the rubber roller 113 to move from the paper outlet 13a to the outside of the paper bin 111. The purpose of setting the disposal port is to limit the position of the hot paper roll, so that the thermal paper roll 112 can move outward from the paper outlet 13a in sequence, and it can also prevent debris from entering the paper bin 111.

[0043] Preferably, one end of the flip cover assembly 114 is pivotally connected to the housing 110 .

[0044] Preferably, the flip cover assembly 114 also includes a sliding buckle plate 134, a return spring 135 and a limit switch member 136. The end of the sliding buckle plate 134 is provided with a movable buckle 141 for locking and fixing the shell 110; further, the sliding buckle plate 134 and the limit switch member 136 are both installed on the upper cover, the limit switch member 136 is used to control the movement of the sliding buckle plate 134, and the two ends of the return spring 135 are respectively fixedly connected to the two ends of the sliding buckle plate 134; it can be understood that the purpose of setting this structure is to elastically act on the sliding buckle plate 134 through the return spring 135, so that when the sliding buckle plate 134 rotates on the shell 110 with the flip cover assembly 114, the sliding buckle plate 134 can be controlled to move through the limit switch member 136. When it is necessary to open the flip cover assembly 114 from the shell 110, the limit switch member 136 can be pulled so that the limit switch member 136 can drive the sliding buckle plate 134 to move. When the sliding buckle plate 134 moves, the movable buckle 141 on the sliding buckle plate 134 will move accordingly, thereby releasing the engagement relationship between the movable buckle 141 and the shell 110. At this time, the flip cover assembly 114 can be rotated relative to the shell 110; and when it is necessary to rotate the flip cover assembly 114 from the shell 110 and engage with the shell 110, the return spring 135 exerts an elastic action on the sliding buckle plate 134 so that the sliding buckle plate 134 can be directly reset by the return spring 135 after penetrating into the shell 110, thereby engaging with the shell 110.

[0045] Preferably, there are two movable buckles 141, and the two movable buckles 141 are respectively arranged on both sides of the sliding buckle plate 134, and a card slot 14a corresponding to the movable buckle 141 is provided on the shell 110. It can be understood that the sliding buckle plate 134 is elastically acted on by the reset spring 135 so that the movable buckle located on the sliding buckle plate 134 can be directly engaged and fixed with the card slot 14a.

[0046] Preferably, the label printer 100 further includes a photo sensor 137 , and the photo sensor 137 is installed on the flip cover assembly 114 and / or the housing 110 .

[0047] According to the above scheme, preferably, in the present embodiment, two photo sensors 137 are provided, and the two photo sensors 137 are respectively installed on the flip cover assembly 114 and the housing 110, and the two photo sensors 137 are respectively arranged opposite to each other. It can be understood that the advantage of providing the photo sensor 137 is that the thermal paper roll 112 moved to that location can be positioned so that the position of the thermal paper roll 112 is accurate, so that the next step of printing can be carried out. By providing the photo sensor 137 to be electrically connected with the control main board 133, the photo sensor 137 transmits the detected signal to the control main board 133, so that it can be determined whether the movement of the thermal paper roll 112 is misplaced, thereby avoiding the situation where the thermal paper roll 112 is misplaced during the movement and is not detected, resulting in misplaced printing, thereby improving the printing accuracy of the label printer 100.

[0048] In summary, the utility model provides a label printer, which can be detachably snapped onto the paper bin by arranging a flap assembly, and presses the thermal paper roll and sticks to the rubber roller when the flap assembly is snapped onto the paper bin, so that the thermal paper roll in the paper bin can be clamped and printed between the rubber roller and the thermal print head when it is driven to move outward by the rotation of the rubber roller and is printed, thereby avoiding the gap between the thermal print head and the rubber roller that causes the thermal paper roll to be misaligned in the moving path during the moving process, ensuring the stable and orderly movement of the thermal paper roll, effectively preventing paper jams, and being applicable to paper rolls of different types and materials, thereby improving the working efficiency and practicality of the label printer and reducing maintenance costs.
