Description

Technical Field

[0001] This utility model relates to the field of magnetic erasure technology, and more specifically, to a magnetic writing board that can be cyclically moved and completely erased. Background Technology

[0002] Magnetic whiteboards and blackboards are innovative products that integrate magnetic technology and writing functionality. They typically use special magnetic materials to make the screen surface and can work in conjunction with matching magnetic writing tools. In appearance, they resemble ordinary whiteboards, blackboards, or displays, but possess unique magnetic sensing characteristics. In daily use, there is no need for traditional ink, chalk, or chalk; writing marks are achieved through magnetic adsorption and sensing. This type of magnetic writing screen has the advantages of being environmentally friendly and energy-saving, avoiding the use and replacement of consumables. Moreover, writing is smooth and the handwriting is clear, and it can be easily erased and rewritten. It is widely used in education, office meetings, family note-taking, and other scenarios. Since erasing the magnetic writing screen directly affects the efficiency of subsequent use, it is necessary to perform erasing operations.

[0003] In related technologies, magnetic whiteboards and blackboards are generally used by writing on one side or flipping them over after writing. Erasure is achieved by using a magnetic eraser.

[0004] However, in the current use of magnetic whiteboards and blackboards, the erasing effect and efficiency of large-size magnetic writing screens and magnetic writing boards using magnetic erasers are not ideal, and staff need to repeatedly move the magnetic eraser to perform the erasing operation, which affects the convenience and efficiency of erasing magnetic whiteboards and blackboards. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easily erasable and reusable magnetic writing board.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a recyclable and movable magnetic writing board, including a magnetic writing screen, a circulating transmission mechanism, and an erasing mechanism; the magnetic writing screen is a flexible screen;

[0008] The magnetic writing screen is disposed on the upper surface of the circulating transmission mechanism and is used for writing; the circulating transmission mechanism is used to circulate the magnetic writing screen.

[0009] The erasing mechanism is located at a certain distance from the lower surface of the circulating transmission mechanism and is used to erase the written content of the magnetic writing screen.

[0010] In a preferred embodiment, the circulating transmission mechanism is provided with a conveyor belt and rollers;

[0011] The magnetic writing screen is attached to the upper surface of the conveyor belt, and rollers are installed on both sides of the conveyor belt.

[0012] The conveyor belt is connected end to end, partially enclosing the two rollers within its lower surface. The rollers drive the conveyor belt and the magnetic writing screen disposed on its surface to rotate cyclically.

[0013] In a preferred embodiment, a support plate is provided on the lower surface of the conveyor belt to support the writing on the magnetic writing screen;

[0014] When the conveyor belt is in motion, it drives the magnetic writing screen to move above the support plate.

[0015] In a preferred embodiment, the erasing mechanism is provided with a magnetic frame located on the lower surface of the conveyor belt; a magnetic strip is provided inside the magnetic frame, and the writing content on the magnetic writing screen is erased by the magnetism of the magnetic strip.

[0016] In a preferred embodiment, multiple magnetic frames are provided.

[0017] In a preferred embodiment, the magnetic frame is set to be the same width as the magnetic writing screen.

[0018] In a preferred embodiment, multiple magnetic strips are provided; the multiple magnetic strips are arranged side by side to form a magnetic strip surface, and the magnetic poles on each individual surface of the magnetic strip surface are consistent.

[0019] In a preferred embodiment, a magnetic shielding device is also included, disposed between the circulating transmission mechanism and the erasing mechanism, to control the erasing mechanism to erase the written content on the magnetic writing screen disposed on the upper surface of the circulating transmission mechanism.

[0020] The reusable magnetic writing board provided by this utility model has the following beneficial effects:

[0021] By setting up a circulating transmission mechanism, a medium for the magnetic writing screen that moves as a whole can be formed inside the magnetic writing screen. This allows users to quickly move the magnetic writing screen to transfer and change the writing surface. As the magnetic writing screen moves, it prepares for subsequent erasing, avoiding the situation where it is difficult to quickly move the magnetic writing screen to transfer and change the writing surface and erase it. This prevents the situation where the eraser needs to be moved repeatedly by the staff during the erasing operation, thus improving the convenience and efficiency of the magnetic writing screen erasing operation.

[0022] By setting up a support plate, a support medium can be formed on the top inside the conveyor belt. Since the size of the support plate matches the size of the magnetic writing screen's writing surface in the empty space inside the frame, it can support the magnetic writing screen and the conveyor belt during use. This avoids the magnetic writing screen being affected by its own flexibility during use, which would make it difficult for users to write smoothly on the magnetic writing screen's writing surface. Therefore, the writing support effect of the magnetic writing screen is improved.

[0023] By setting up an erasing mechanism, a magnetic erasing medium can be formed on the opposite side of the writing surface of the magnetic writing screen. As the magnetic writing screen moves and is transferred with the roller and conveyor belt, the writing marks on the opposite side of the writing surface of the magnetic writing screen are magnetically erased. This avoids the situation where writing marks are difficult to erase after the writing surface of the magnetic writing screen is transferred and replaced, thus improving the overall ease and efficiency of erasing the magnetic writing screen.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-3 This utility model provides a technical solution: a recyclable and movable magnetic writing board, including a magnetic writing screen 2, a circulating transmission mechanism, and an erasing mechanism; the magnetic writing screen 2 is a flexible screen, and a medium for the overall movement of the magnetic writing screen 2 can be formed on the inner side of the magnetic writing screen 2, so that the user can quickly move the magnetic writing screen 2 to transfer and change the writing surface. As the magnetic writing screen 2 moves, it can prepare the magnetic writing screen 2 for subsequent erasing, avoiding the situation where it is difficult to quickly move the magnetic writing screen 2 to transfer and change the writing surface and erase it during use, which would require the staff to repeatedly move the magnetic board to erase during the erasing operation. Therefore, the convenience and efficiency of the erasing operation of the magnetic writing screen 2 are improved.

[0031] Reference Figures 1-3In a preferred embodiment, the magnetic writing screen 2 is disposed on the upper surface of the circulating transmission mechanism for writing; the circulating transmission mechanism is used to circulate and move the magnetic writing screen 2, and the erasing mechanism is disposed at a certain distance on the lower surface of the circulating transmission mechanism for erasing the written content of the magnetic writing screen 2. The writing surface is transferred and replaced by the roller 4 in conjunction with the conveyor belt 3 to facilitate subsequent writing operations. During the process, as the writing surface of the magnetic writing screen 2 is transferred and replaced, when the magnetic writing screen 2 with writing marks moves to the bottom of the first magnetic strip 8, since the writing screen is made of two colors of nanoparticles and suspension encapsulated in microcapsules, under the action of a near-vertical magnetic field, the particles of one color are attracted to float to the top, thereby changing the color and contrast, thus realizing the writing display function; under the movement action of a large-area dispersed magnetic field, the floating particles are attracted to the sides or other parts of the capsule, while the particles of the other color fill the positions of the floating particles, thus realizing the erasing function. These microcapsules are coated on PET or other materials. A magnetic writing screen 2 is made by attaching or coating a protective layer onto a transparent material. This allows for the transfer and replacement of the writing surface and the erasure of writing marks. The circulating transmission mechanism includes a conveyor belt 3 and rollers 4. The magnetic writing screen 2 is attached to the upper surface of the conveyor belt 3, and rollers 4 are installed on both sides of the conveyor belt 3. The two rollers 4 are partially enclosed in the lower surface of the conveyor belt 3, which drives the conveyor belt 3 and the magnetic writing screen 2 on its surface to rotate in a circular motion. This creates a medium for the magnetic writing screen 2 to move as a whole, allowing users to quickly move the magnetic writing screen 2 to transfer and replace the writing surface. It also prepares the magnetic writing screen 2 for subsequent erasure, avoiding the difficulty of quickly moving the magnetic writing screen 2 to transfer and replace the writing surface and the need for repeated movement of the magnetic eraser during the erasure operation. Therefore, the convenience and efficiency of the magnetic writing screen 2's erasure operation are improved.

[0032] Reference Figures 1-3In a preferred embodiment, a support plate 5 is provided on the lower surface of the conveyor belt 3 to support the writing of the magnetic writing screen 2. When the conveyor belt 3 is in motion, it drives the magnetic writing screen 2 to move above the support plate 5, forming a support medium on the top of the inner side of the conveyor belt 3. Since the size of the support plate 5 matches the size of the writing surface of the magnetic writing screen 2 in the empty space inside the frame 1, it can support the magnetic writing screen 2 and the conveyor belt 3 during use, avoiding the situation where the user has difficulty writing smoothly on the writing surface of the magnetic writing screen 2 due to its own flexibility. Therefore, the writing support effect of the magnetic writing screen 2 is improved. The erasing mechanism is provided with a magnetic frame 6, which is located on the lower surface of the conveyor belt 3. A magnetic strip 8 is provided inside the magnetic frame 6. The magnetic strip 8 erases the writing content on the magnetic writing screen 2 by its magnetism. Since the length of the first magnetic strip 8 is the same as the flexible magnetic writing screen attached to the conveyor belt 3, the magnetic writing screen 2 is supported by the support plate 5. The writing screen 2 is the same width as the magnetic writing screen 2. The width of the first magnetic strip 8 is between 5mm and 100mm, and it can also be made up of multiple magnets spliced ​​together. The surface of the first magnetic strip 8 can be parallel to the conveyor belt 3. The entire surface of the first magnetic strip 8 must be N pole or S pole, and the magnetic field strength is between 100 Gauss and 3000 Gauss. A magnetic shielding material device is added between the magnet device and the conveyor belt 3, and an erasing switch is added for control. When the switch is open, the magnetic field of the first magnetic strip 8 can act on the magnetic writing screen 2 to realize the erasing function of the magnetic writing screen 2. When the switch is closed, the magnetic field of the first magnetic strip 8 is shielded, and the content of the magnetic writing screen 2 can be retained. As the roller 4 moves and transfers the magnetic writing screen 2 in conjunction with the conveyor belt 3, the writing marks on the opposite side of the writing surface of the magnetic writing screen 2 are magnetically erased. This avoids the situation where the writing marks are difficult to erase after the writing surface of the magnetic writing screen 2 is transferred and replaced, thus improving the overall erasing convenience and efficiency of the magnetic writing screen 2.

[0033] Reference Figures 1-3 In a preferred embodiment, by providing multiple magnetic frames 6, since the second magnetic strip 11 is designed the same as the first magnetic strip 8, the second magnetic strip 11 only increases the spacing distance with the magnetic writing screen 2. After the writing marks on the magnetic writing screen 2 are magnetically erased by the first magnetic strip 8, when they pass through the second magnetic strip 11, the background color of the magnetic writing screen 2 will be closer to the color of nanoparticles that are not attracted by the magnetic field. This results in better contrast when writing again, allowing the user to perform writing operations better in the future, thus improving the writing effect of the magnetic writing screen 2.

[0034] Specifically, the working process or principle of this recyclable magnetic writing board is as follows: When the writing surface of the magnetic writing screen 2, located inside the frame 1, is used for writing and requires erasing, the magnetic writing screen 2 is attached to the conveyor belt 3. The conveyor belt 3, passing over rollers 4 at both ends, forms a circulating transmission mechanism. The conveyor belt 3 can be moved manually or electrically. The magnetic writing screen 2 is transferred and its writing surface replaced to facilitate subsequent writing operations. A support plate 5 is installed in the writing area, allowing the conveyor belt 3 to move on top of it. During writing, the support plate 5 provides support for the magnetic writing screen 2 attached to the conveyor belt 3. As the magnetic writing screen 2 is transferred by the conveyor belt 3, the writing surface of the magnetic writing screen 2 with writing marks passes the first magnetic strip 8. The length of the first magnetic strip 8 is the same as the width of the magnetic writing screen 2 attached to the conveyor belt 3. A magnetic shielding material device is added between the magnetic writing screen 2 and the conveyor belt 3, and an erasure switch is added for control. When the switch is open, the magnetic field of the first magnetic strip 8 can act on the magnetic writing screen 2 to erase the writing marks on the magnetic writing screen 2, thus realizing the erasure function. When the switch is closed, the magnetic field of the first magnetic strip 8 is shielded, and the content of the magnetic writing screen 2 can be retained. After writing on one board, the conveyor belt 3 can be moved to continue writing. At the same time, the erasure switch can be used to select whether to erase all the writing content. After the writing marks on the magnetic writing screen 2 are magnetically erased by the first magnetic strip 8, when they pass through the second magnetic strip 11, the background color of the magnetic writing screen 2 will be closer to the color of nanoparticles that are not attracted by the magnetic field. This results in better contrast when writing again, so that the user can perform writing operations better in the future. This realizes the function of transferring and changing the writing surface while erasing the writing marks, so that the user can perform writing operations continuously.
