Description

Technical Field

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

[0002] Portable label printers are increasingly used in modern logistics, retail, warehousing, and other fields, and the demand for fast, accurate, and convenient label printing is constantly growing. However, existing portable label printer mechanisms have certain limitations in design and functionality.

[0003] On the one hand, existing printer mechanisms are often structurally complex, with an unreasonable layout between components, leading to greater assembly and maintenance difficulties and increasing production costs. On the other hand, existing printer mechanisms often lack perfection in functions such as motion monitoring, pattern printing, paper driving, and cutting during the printing process, affecting printing accuracy and efficiency. For example, the motion monitoring of thermal roll paper is not precise enough, which can easily lead to printing misalignment or blurriness; the coordination between the printing mechanism and the paper driving mechanism is not coordinated enough, affecting printing speed and quality; and an unreasonable design of the cutting mechanism may result in uneven cutting or damage to the paper.

[0004] To address the aforementioned problems, this utility model document proposes a portable label printer mechanism. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing printer mechanisms, such as complex structure, unreasonable layout, and insufficient functionality, which affect mechanism maintenance and printing effect, and to propose a portable label printer mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable label printer mechanism includes:

[0008] A flip-top assembly and a paper tray assembly, wherein the flip-top assembly is hinged to the top of the paper tray assembly, and the paper tray assembly contains a thermal paper roll.

[0009] The flip-top assembly is equipped with a printing mechanism and a locking mechanism. The printing mechanism includes an upper photosensitive sensor and a thermal printhead, which are used to monitor the movement of the thermal roll paper and print patterns. The locking mechanism includes a flip-top latch, which is used to lock the flip-top assembly and the paper tray assembly.

[0010] The paper tray assembly is equipped with a drive mechanism, which includes a rubber roller for driving the movement of the thermal paper roll.

[0011] The flip-top assembly and the paper tray assembly work together to complete the printing and cutting of thermal roll paper.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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 and the rubber roller are aligned, with the thermal roll paper 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 printhead will print the text and image onto the thermal roll paper. As the thermal roll paper moves, the lower and upper photosensitive sensors align with each other, detecting the distance the thermal roll paper has moved. When the thermal roll paper has moved the appropriate distance, the signals from the lower and upper photosensitive sensors control the printer to pause the drive, thus completing one printing of the label. Afterward, the user only needs to pull one end of the thermal roll paper and lift it upward, allowing the thermal roll paper to contact the cutting blade, thus completing the cutting of the thermal roll paper and obtaining the printed label. 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 latch back and disengage the two claws of the flip cover latch from the latching slot, allowing the user to rotate and open the flip cover assembly for easy replenishment of thermal roll paper and maintenance of the equipment.

[0017] Beneficial effects: The portable label printer mechanism described in this utility model has a compact structure and reasonable layout. It cleverly combines the flip cover assembly and the paper tray assembly, and realizes convenient opening and closing of the flip cover through the hinge method. At the same time, the integrated design of the internal components reduces the difficulty of assembly and maintenance, and reduces production costs.

[0018] In this utility model, the portable label printer mechanism has a precise and efficient printing mechanism. The cooperation between the upper photosensitive sensor and the thermal printhead enables accurate monitoring of the thermal roll paper movement distance and clear printing of patterns, improving printing accuracy and quality. At the same time, the locking mechanism ensures a stable connection between the flip-top assembly and the paper tray assembly, preventing accidental opening during the printing process.

[0019] In this utility model, the portable label printer mechanism has a stable and reliable drive mechanism. It is equipped with a motor that drives the rubber roller to rotate through a gear set, thereby achieving smooth movement of the thermal paper roll and ensuring the continuity and stability of printing. The clever design of the paper cutter allows the printed labels to be cut off quickly and neatly, improving work efficiency.

[0034] Example 2: Reference Figure 2 , 3 4. Improvement based on Example 1: A portable label printer mechanism, which is applied to the field of printer technology;

[0035] In this embodiment, the locking mechanism includes a flip-top latch 12, used to lock the flip-top assembly and the paper tray assembly. The flip-top latch 12 is slidably disposed inside the flip-top 1, and has claws integrally provided on both sides. Both claws pass through the inner support 11 of the flip-top via a preset sliding groove and slide in cooperation with the inner support 11 of the flip-top. Both sides of the paper tray 2 have a latching groove 10, and both claws engage with the corresponding latching groove 10 to close and lock the flip-top assembly. Two flip-top latch springs 13 are fixedly installed on one side of the flip-top latch 12, and the other ends of the two flip-top latch springs 13 are fixedly connected to the inner wall of one side of the flip-top 1. In addition, the flip-top assembly also includes an opening switch 19 slidably installed on the top of the flip-top 1 via a sliding groove. The bottom end of the opening switch 19 passes through the top inner wall of the flip-top 1 and cooperates with one side of the flip-top latch 12 to push the flip-top latch 12, thereby unlocking the flip-top assembly.

[0036] 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.

[0037] 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 and extends 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 attached to the thermal paper roll 3. The printer control motor 4 starts and drives the rubber roller 7 to rotate, which in turn moves the thermal paper roll 3. When the thermal printhead 15 moves, it prints text and images onto the thermal roll paper 3. As the thermal roll paper 3 moves, the lower photosensitive sensor 9 and the upper photosensitive sensor 14 align with each other, recognizing the distance the thermal roll paper 3 has moved. Once the thermal roll paper 3 has moved a suitable distance, the signals from the lower and upper photosensitive sensors 9 and 14 control the printer to pause, thus completing one label print. Afterward, the user simply pulls one end of the thermal roll paper 3 and lifts it upward, allowing the thermal roll paper 3 to contact the cutting blade 18, thus cutting the thermal roll paper 3 and obtaining the printed label. When the user needs to replace the thermal roll paper 3, they simply toggle the cover switch 19. The cover switch 19 abuts against the flip cover latch 12, causing the two claws of the flip cover latch 12 to disengage from the latching groove 10. This allows the user to rotate and open the flip cover assembly, facilitating the replenishment of the thermal roll paper 3 and equipment maintenance.

[0038] 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 and thermal printhead 15 are commonplace and are all 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.

[0039] 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.

[0040] 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. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
