Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to a portable label printer. Background Technology

[0002] Portable label printers play an important role in daily life and business applications, and are widely used in scenarios such as item sorting, warehousing and logistics information labeling, and supermarket product classification. However, traditional portable label printers have many shortcomings in design and structure, affecting their user experience and efficiency.

[0003] Specifically, existing portable label printers have significant flaws in the layout of their internal components. The placement of key components such as the thermal printhead assembly, paper tray, motor drive assembly, rubber rollers, and photosensor is not reasonable, leading to a complex assembly process, increased production costs, and greater maintenance difficulty. In addition, the unreasonable layout also affects the overall performance of the printer, resulting in slower printing speeds, unclear print quality, inaccurate paper feeding, and a tendency to jam. These problems not only reduce printing efficiency but also increase the user's operating costs and time costs.

[0004] In terms of portability, existing portable label printers are often large and not compact enough to meet users' needs in different scenarios. At the same time, the maintenance process of existing label printers is cumbersome. Operations such as replacing thermal paper rolls and repairing equipment are not simple enough, which further affects the user experience.

[0005] To address the aforementioned problems, this utility model document proposes a portable label printer. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing portable label printers, such as unreasonable layout, poor performance, large size, poor portability, and cumbersome maintenance and operation, and to propose a portable label printer.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] In one possible design, the flip-cover assembly includes a flip cover and an inner support bracket. The inner support bracket is fixedly installed inside the flip cover and located near the bottom opening of the flip cover. An upper photosensitive sensor is fixedly installed inside the flip cover, with one end of the upper photosensitive sensor penetrating through the inner support bracket and extending outside the flip cover. The detection end of the upper photosensitive sensor corresponds to a pre-set hole at the bottom of the inner support bracket. A printhead bracket is slidably installed inside the inner support bracket via a slide groove. The thermal printhead is fixedly installed at the bottom of the printhead bracket, and the printing surface of the thermal printhead penetrates through a pre-set hole at the bottom of the inner support bracket. A printhead spring is fixedly installed on the bottom inner wall of the printhead bracket, and the other end of the printhead spring is fixedly connected to the top inner wall of the flip cover.

[0016] In one possible design, the paper tray assembly includes a paper tray with an internal cavity for holding thermal paper rolls. The top of the paper tray has a paper passage for the thermal paper rolls. A hinged flap is hinged to the top of the paper tray to enable connection and rotation of the flap assembly. A lower photosensitive sensor is fixedly installed inside the paper tray, with its detection end penetrating the top of the paper tray. The lower photosensitive sensor cooperates with an upper photosensitive sensor to detect the forward distance of the thermal paper rolls. A rubber roller is rotatably mounted on the top of the paper tray, cooperating with the thermal paper rolls. The top of the paper tray is fixedly equipped with… A rubber roller pressure plate is provided to press and fix the rubber roller. A motor is fixedly installed inside the paper compartment. One end of the motor's output shaft passes through one side of the paper compartment and is fixedly installed with a drive gear. A gear set is provided on one side of the paper compartment. The gear set consists of multiple meshing gears. A gear set pressure plate is fixedly installed on one side of the paper compartment. The multiple gears are rotatably connected to the gear set pressure plate near the paper compartment. A connecting gear is fixedly installed at one end of the rubber roller. The motor, through the transmission of the gear set, can realize the drive gear to drive the connecting gear, thereby realizing the rotation of the rubber roller.

[0017] In one possible design, the flip-top assembly further includes an opening switch slidably mounted on the top of the flip-top via a slide groove. The bottom end of the opening switch penetrates the inner wall of the top of the flip-top. The flip-top latch is slidably disposed inside the flip-top. Both sides of the flip-top latch are integrally provided with claws. Both claws penetrate the inner support of the flip-top via a preset slide groove and slide in cooperation with the inner support of the flip-top. Both sides of the paper tray are provided with locking grooves. Both claws engage with the corresponding locking grooves to complete the closing and locking of the flip-top assembly. Two flip-top latch springs are fixedly installed on one side of the flip-top latch. The other ends of the two flip-top latch springs are fixedly connected to the inner wall of one side of the flip-top. The bottom end of the opening switch cooperates with one side of the flip-top latch. The opening switch is used to push the flip-top latch, thereby unlocking the flip-top assembly.

[0018] In one possible design, a paper cutter is fixedly installed on one side of the inner support of the flip cover for cutting the printed thermal roll paper.

[0019] In one possible design, the PCBA assembly is electrically connected to the motor, lower photosensor, upper photosensor, and thermal printhead to ensure proper printer operation.

[0020] In this application, during use, the user can place the thermal roll paper to be used in the paper tray, then pull one end of the thermal roll paper out into the paper feed path and extend it outside the paper tray. The user can then rotate the flip cover to close it. When the flip cover is closed, the bottom ends of the two claws of the flip cover latch will abut against the corresponding latching grooves. Then, under the yielding action of the flip cover latch spring and subsequent pushing effect, the two claws of the flip cover latch will automatically lock into the latching grooves and remain engaged, ensuring that the flip cover will not be accidentally opened during printer use. When the printer is working, the thermal print head corresponds to the rubber roller, and the thermal roll paper is located between them. Under the action of the print head spring, the printing surface of the thermal print head can be tightly pressed against the thermal roll paper. The printer control motor starts, driving the rubber roller to rotate, which in turn moves the thermal roll paper. At this time, the thermal print head... The text and images will be printed onto the thermal roll paper. As the thermal roll paper moves, the lower and upper photosensitive sensors align with each other, which can detect the distance the thermal roll paper moves. When the thermal roll paper moves the appropriate distance, it will send a signal to the PCBA component, which will then control the printer to stop, thus completing one label printing. Afterwards, the user only needs to pull one end of the thermal roll paper and lift it upwards. The thermal roll paper will then contact the cutting blade, completing the cutting of the thermal roll paper, and the printed label can then be obtained. When the user needs to replace the thermal roll paper, simply toggle the cover switch to move it. The cover switch will push the flip cover back and cause the two claws of the flip cover to no longer engage with the latching slot. At this time, the user can rotate and open the flip cover assembly, which is convenient for replenishing the thermal roll paper and maintaining the equipment.

[0021] Beneficial effects: The portable label printer described in this utility model has a compact and portable structure; by rationally arranging key components such as the thermal printhead assembly, paper tray, motor drive assembly, circuit board assembly, photosensor, and rubber roller, the overall size of the printer is reduced, making it easy to carry and use;

[0040] This application can be used in the field of printer technology, or in other fields applicable to this application.

[0041] Example 2: Reference Figure 2 , 6 An improvement on Example 1: a portable label printer, which is applied to the field of printer technology;

[0042] In this embodiment, a paper cutter 18 is also fixedly installed on one side of the inner support 11 of the flip cover. The cutting edge of the paper cutter 18 faces downward. The user only needs to pull the printed thermal paper roll 3 and pull it upward, and the thermal paper roll 3 can contact the paper cutter 18 and complete the corresponding cutting.

[0043] In this embodiment, two housings 20 are located on both sides of the paper tray assembly 22, with the paper tray assembly 22 positioned near the top of the two housings 20. The two housings 20 are interlocked and fixedly connected to protect the internal parts and to form the main body of the printer.

[0044] In this embodiment, the PCBA assembly 23 is located between the two housings 20 and below the paper tray assembly 22. The PCBA assembly 23 is fixedly connected to one side of one of the housings 20. The PCBA assembly 23 is electrically connected to the motor 4, the lower photosensor 9, the upper photosensor 14, and the thermal printhead 15 to ensure the normal operation of the printer.

[0045] The working principle and usage process of this technical solution are as follows: During use, the user places the thermal paper roll 3 to be used in the paper tray 2, then pulls one end of the thermal paper roll 3 into the paper feed channel, extending it outside the paper tray 2. The user can then rotate the flip cover 1 to close it. When the flip cover 1 is closed, the bottom ends of the two claws of the flip cover latch 12 abut against the corresponding latching groove 10. Then, under the yielding action of the flip cover latch spring 13 and subsequent pushing effect, the two claws of the flip cover latch 12 automatically engage in the latching groove 10 and remain engaged with it, ensuring that the flip cover 1 will not be accidentally opened during printer use. When the printer is working, the thermal print head 15 corresponds to the rubber roller 7, and the thermal paper roll 3 is located between them. Under the action of the print head spring 17, the printing surface of the thermal print head 15 can be tightly pressed against the thermal paper roll 3. The printer control motor 4 starts, driving the rubber roller 7 to rotate, which in turn moves the thermal paper roll 3. At this time, the thermal printhead 15 will print the text image onto the thermal roll paper 3. When the thermal roll paper 3 moves, the lower photosensitive sensor 9 and the upper photosensitive sensor 14 are aligned with each other, which can detect the moving distance of the thermal roll paper 3. When the thermal roll paper 3 moves a suitable distance, it will send a signal to the PCBA assembly 23, which can then control the printer to stop. At this time, the label can be printed once. Afterwards, the user only needs to pull one end of the thermal roll paper 3 and lift it up. The thermal roll paper 3 can contact the blade of the paper cutter 18 to cut the thermal roll paper 3, and then the printed label can be obtained. When the user needs to replace the thermal roll paper 3, he only needs to move the cover switch 19. The cover switch 19 can abut against the flip cover latch 12 and make the two claws of the flip cover latch 12 no longer engage with the latching groove 10. At this time, the user can rotate and open the flip cover assembly 21, which can facilitate the replenishment of the thermal roll paper 3 and the maintenance of the equipment.

[0046] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 4, lower photosensitive sensor 9, upper photosensitive sensor 14, thermal printhead 15 and PCBA assembly 23 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0047] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
