[0039] Please see Figure 1-8This utility model provides a rolling memorization aid device, including a support 1, a frame 2, a shielding shell 3, a connector 4, a detachable roller 5, a fixed roller 6, a connecting mechanism 7, a positioning mechanism 8, and a linkage mechanism 9. The frame 2 is fixedly mounted on the support 1, and the shielding shell 3 is fixedly mounted on one outer wall of the frame 2. Two rotating shafts 31 are rotatably mounted on one inner wall of the shielding shell 3, with the other end of each shaft 31 extending into the frame 2. A drive motor 32 is mounted on one outer wall of the shielding shell 3, and the output shaft of the drive motor 32 is fixedly connected to one of the rotating shafts 31. The connector... 4 is fixedly installed at one end of one of the rotating shafts 31. The detachable roller 5 is detachably connected to the connector 4. The fixed roller 6 is fixedly installed at one end of the other rotating shaft 31. The connecting mechanism 7 is installed inside the connector 4. The connecting mechanism 7 is used to complete the connection between the detachable roller 5 and the connector 4. The positioning mechanism 8 is installed on the detachable roller 5 and the fixed roller 6. The positioning mechanism 8 is used to position the paper on the detachable roller 5 and the fixed roller 6. The linkage mechanism 9 is installed inside the shielding shell 3. The linkage mechanism 9 is used to drive the detachable roller 5 and the fixed roller 6 to rotate synchronously.

[0040] The above-described structure constitutes a complete rolling memorization aid system. The support frame 1 provides the foundation for the entire device; the frame 2, as the main load-bearing structure, is fixed to the support frame 1, providing installation space for internal components; the shielding shell 3 protects the internal rotating shaft 31 and linkage mechanism 9, preventing accidental contact and enhancing aesthetics; the two rotating shafts 31 connect the detachable roller 5 and the fixed roller 6 respectively, serving as the core transmission components for paper rolling; the drive motor 32 provides power to the device; the connector 4 enables the detachable connection between the detachable roller 5 and the rotating shaft 31; the detachable roller 5 and the fixed roller 6 are used to wind the paper carrying the memorization content; the connecting mechanism 7, positioning mechanism 8, and linkage mechanism 9 respectively realize the functions of roller assembly / disassembly, paper fixing, and synchronous transmission, jointly ensuring the convenience and stability of the device.

[0041] To further explain, the detachable roller 5 and the fixed roller 6 are made of ABS engineering plastic injection molding and have a matte finish, which reduces paper reflection and prevents paper slippage.

[0042] Further explanation: The connecting mechanism 7 includes a slot 71 formed on the connector 4. Two symmetrically distributed grooves 72 are formed on one side wall of the slot 71. A slider 73 slides within each groove 72. A claw 74 is fixedly connected to the side wall of the slider 73 closest to the detachable roller 5. A first spring 75 is provided between the slider 73 and the groove 72. A pressing block 76 is fixedly connected to the side wall of the two sliders 73 away from each other, with the other end of the pressing block 76 extending outside the connector 4. Through the above structural design, the detachable roller 5 and the connector 4 can be quickly assembled and disassembled, significantly improving the efficiency of paper replacement.

[0043] Further explanation: The positioning mechanism 8 includes a groove 81 formed on the detachable roller 5 and the fixed roller 6. A guide groove 82 is formed on the upper side wall of the groove 81. A positioning plate 83 is slidably disposed within the guide groove 82. Multiple second springs 84 are provided between the upper side wall of the positioning plate 83 and the guide groove 82. The guide groove 82 penetrates one side wall of both the detachable roller 5 and the fixed roller 6. A lever 85 is fixedly connected to one side wall of the positioning plate 83. The lever 85 extends through the guide groove 82 to the outside of both the detachable roller 5 and the fixed roller 6. This allows for quick and easy fixing of paper wound on the detachable roller 5 and the fixed roller 6, making operation more convenient.

[0044] To further explain, the linkage mechanism 9 includes two pulleys 91, which are respectively fixedly mounted on two rotating shafts 31. The two pulleys 91 are driven by a toothed belt 92. This achieves synchronous rotation of the two rotating shafts 31, avoiding paper wrinkling or breakage due to different rotation speeds, and ensuring that the recitation content is displayed smoothly.

[0045] To further explain, the two pulleys 91 have the same diameter and are driven by the meshing of the toothed belt 92 to ensure that the rotation speeds of the two rotating shafts 31 are completely consistent, thereby enabling the detachable roller 5 and the fixed roller 6 to rotate synchronously and avoid paper stretching, wrinkling or breaking due to differences in rotation speed.

[0046] To further explain, one end of the detachable roller 5 is fixedly connected to a plug 51 that matches the slot 71. The upper and lower side walls of the plug 51 are provided with slots 52 that match the claws 74. When the plug 51 is inserted into the slot 71, the slots 52 can accurately accommodate the claws 74, ensuring a stable connection between the detachable roller 5 and the connector 4. When disassembling, the claws 74 disengage from the slots 52, and the plug 51 can be easily removed from the slot 71, further improving the convenience of disassembly and assembly.

[0047] To further explain, a light strip 21 is embedded in the upper inner wall of frame 2. This provides illumination in low-light environments, ensuring users can clearly see the content to be memorized, avoiding any impact on memorization efficiency due to lighting issues, and improving the device's environmental adaptability. The light strip 21 is an LED flexible light strip, and its brightness can be switched between three levels via controller 11.

[0048] To further explain, anti-slip pads are provided at the four corners of the bottom of the bracket 1. This increases the friction between the bracket 1 and the placement surface, preventing the device from sliding during use and ensuring its stability.

[0049] To further explain, the drive motor 32 is a variable frequency speed control motor, and a controller 11 is installed on the bracket 1. Both the drive motor 32 and the light strip 21 are electrically connected to the controller 11. Users can adjust the speed of the drive motor 32 through the controller 11, thereby controlling the scrolling speed of the paper: the speed can be reduced when the memorization speed is slow, and the speed can be increased when reviewing quickly, meeting the personalized needs of different users and different memorization scenarios, and improving the flexibility of the device.

[0050] It should be noted that the controller 11 uses an STM32 microcontroller. The input and output pins of the microcontroller are connected to the drive motor 32 and the light strip 21 as described above, and this can be achieved by programming the microcontroller. The circuit and program used are common technologies in the field of microcontrollers. Those skilled in the art can easily derive the specific circuit based on the above control relationship description. Therefore, the specific circuit will not be described in detail here.

[0051] It should be noted that this utility model is a rolling memorization aid device. In use, first disassemble the detachable roller 5, press the pressing blocks 76 on both sides of the connecting piece 4 to move the claws 74 and disengage them from the slots 52 on the insert block 51. Then, remove the insert block 51 of the detachable roller 5 from the slot 71 of the connecting piece 4. Move the lever 85 on the detachable roller 5 to move the positioning plate 83 upwards, insert one end of the paper into the groove 81, release the lever 85, and the positioning plate 83 presses the paper under the action of the second spring 84, smoothly wrapping the paper around the detachable roller 5. After completion, reinstall the detachable roller 5 into the connecting piece 4, insert the insert block 51 into the slot 71, and after releasing the pressing blocks 76, the claws 74 engage with the slots under the push of the first spring 75. Within 52, fix the detachable roller 5, repeat the above operation of the dial 85, and fix the other end of the paper in the groove 81 of the fixed roller 6, ensuring that the paper is taut and flat. Start the drive motor 32 through the controller 11. According to the memorization needs, adjust the speed of the drive motor 32 through the controller 11. The drive motor 32 drives one of the rotating shafts 31 to rotate. Through the pulley 91 and toothed belt 92 of the linkage mechanism 9, the two rotating shafts 31 rotate synchronously. The detachable roller 5 and the fixed roller 6 rotate synchronously. The paper slowly rolls to display the memorization content. If you need to pause, turn off the drive motor 32 through the controller 11 to fix the memorization content. During the memorization process, if the environment is dark, you can turn on the light strip 21 through the controller 11 to assist reading.
