[0035] As shown in Figures 1 to 7, this utility model discloses a fully automatic quick-change smart dining table, including a table body 1 and a roll-up assembly and a roll-down assembly respectively disposed on its end sides. Both the roll-up and roll-down assemblies include a bracket 2 fixed to the end face of the table body 1. A fixing plate 21 is fixed to one side of the bracket 2. A support roller 22 for supporting a tablecloth roll 100 is pivotally mounted on the fixing plate 21. The outer circumferential surface of the support roller 22 is located below the upper surface of the table body 1. In this utility model, the location of the support roller 22 on the upper surface of the table body makes the overall layout more aesthetically pleasing. Simultaneously, it ensures that the tablecloth on the tablecloth roll 100 is completely flush with the table body 1, thus making the dining table more convenient and efficient to use, greatly improving ease of use.

[0036] A movable plate 23 is movably provided on the other side of the support 2. The movable plate 23 can be locked onto the support 2 by a locking assembly 9. A limiting block 24 is pivotally provided on the movable plate 23. The central axis of the limiting block 24 is coaxial with the central axis of the carrying roller 22, and can extend at least partially into the tablecloth roll 100. In this utility model, the tablecloth roll sleeved on the carrying roller 22 can be quickly replaced by opening or closing the movable plate 23. This operation is simple and convenient, greatly improving work efficiency. In addition, when the movable plate 23 is closed, the limiting block 24 can be engaged with the tablecloth roll, accurately positioning the tablecloth roll on the carrying roller, thereby ensuring the accuracy of subsequent winding and achieving efficient and accurate winding.

[0037] Specifically, the locking assembly 9 includes at least a sliding hole formed on the movable plate 23, a sliding rod 91 disposed within the sliding hole, a fixing block fixed at one end of the sliding rod 91, the inner wall of the fixing block abutting against the outer wall of the movable plate 23, and a locking block 92 disposed on the other side of the sliding rod 91. A locking groove 93 adapted to the locking block 92 is formed on the bracket 2, allowing the locking block 92 to be placed within the locking groove 93. A spring is fitted onto the sliding rod 91, one end of the spring abutting against the movable plate 23, and the other end abutting against the locking block 92. By pulling the sliding rod 91, the locking block 92 can be disengaged from the locking groove 93. Rotating the sliding rod 91 to the corresponding position allows the movable plate to pivot on the bracket 2. This operation is simple and convenient, enabling quick disassembly and replacement of the tablecloth roll, greatly improving work efficiency. Furthermore, this structure is reusable, significantly reducing costs.

[0038] Furthermore, a groove 25 is provided on the outer circumferential surface of the bearing roller 22. The groove 25 reduces the weight of the dining table, achieving lightweight design. Additionally, a positioning piece 27 is fixed within the groove 25 by a locking screw 26. The positioning piece 27 is V-shaped and at least partially extends outside the outer circumferential surface of the bearing roller 22. The positioning piece 27 abuts against the inner wall of the tablecloth roll, preventing the tablecloth roll from shifting or displacing due to inertia, thus improving the accuracy of unwinding. Furthermore, the positioning piece 27 adopts a quick-connect structure, facilitating disassembly, replacement, and maintenance, greatly improving work efficiency.

[0039] In this invention, a rotating shaft 3 is pivotally mounted on the fixed plate 21 located on the winding assembly. The bearing roller 22 is fixedly mounted on the rotating shaft 3. A drive motor 31 is fixedly mounted on the bracket 2. A drive wheel 32 is fixedly mounted on the motor shaft of the drive motor 31. A driven wheel 33 is pivotally mounted on the rotating shaft 3. A transmission belt 34 is wound between the drive wheel 32 and the driven wheel 33. When the drive motor 31 starts, it drives the rotating shaft 3 to rotate sequentially through the drive wheel 32, the transmission belt 24, and the driven wheel 33. The rotating shaft 3 then drives the bearing roller 22 to rotate, thereby achieving winding. Using a motor for winding takes advantage of its high transmission accuracy and stable reliability.

[0040] Additionally, a fixed shaft 4 is fixedly mounted on the fixed plate 21 located on the unwinding assembly. A fixed flange 41 is fixedly mounted on one end of the fixed shaft 4, and the bearing roller 22 is pivotally mounted on the other end. A torsion spring 42 is sleeved on the fixed shaft 4, with one end of the torsion spring 42 fixedly connected to the fixed flange 41 and the other end fixedly connected to the bearing roller 22. The torsion spring 42 serves as a damping element, preventing the tablecloth roll 100 from shifting due to inertia, thereby ensuring the accuracy of unwinding.

[0041] An arc-shaped lower support plate 5 is fixedly mounted on the bracket 2. An upper support plate 6 is slidably mounted above the lower support plate 5. The lower support plate 5, the upper support plate 6, the fixed plate 21, and the movable plate 23 define a sealed cavity, and the tablecloth roll 100 is placed inside the sealed cavity. Placing the tablecloth roll inside the sealed cavity ensures the cleanliness of the tablecloth roll on the unloading assembly and also improves its aesthetics.

[0042] In this design, a support block 61 is fixedly mounted on the bracket 2, and the upper support plate 6 is slidably mounted on the support block 61. The upper support plate 6 and the lower support plate 5 are connected by a latch 62. A sensor 63 is also provided on the bracket 2, located at both ends of the upper support plate 6. The sensor allows for real-time monitoring of the position of the upper support plate. Furthermore, the latch 62 connection between the upper and lower support plates prevents accidental opening or misoperation, thus improving safety.

[0043] The table body 1 is equipped with two start buttons 7, which are interlocked with the drive motor 31. This design significantly improves safety and prevents accidental operation.

[0044] In this utility model, a drive shaft 8 is pivotally connected between the winding assembly and the table body 1 and the unwinding assembly and the table body 1. A drive wheel 84 is fixed on the drive shaft 8. A transmission motor 85 is fixed on the bracket 2. A transmission wheel 86 is fixed on the motor shaft of the transmission motor 85. A drive belt 87 is wound between the drive wheel 84 and the transmission wheel 86. An eccentric block 81 is provided on the drive shaft 8. A flip plate 82 is fixed on the eccentric block 81. A guide roller 83 is also fixed on the inner side of the drive shaft 8.

[0045] When the drive motor 85 is started, the drive motor 85 drives the drive shaft 8 to rotate through the drive wheel 86, drive belt 87 and drive wheel 84. The rotation of the drive shaft 8 drives the flip plate 82 to rotate to the corresponding angle through the eccentric block 81. At this time, the winding assembly and unwinding assembly can perform winding and unwinding operations. After the operation is completed, the flip plate can be reset by controlling the drive motor 85 to keep the table clean and beautiful.

[0046] The above layout is reasonable. After the winding and unwinding components are completed, the flip plate can be controlled to rotate to a horizontal position, thus maintaining the cleanliness and appearance of the dining table. At the same time, it can also prevent dust and debris from entering the winding or unwinding components, improving the cleanliness of the tablecloth roll. In addition, the guide roller 83 can also play a guiding and correcting role, improving the stability and accuracy of winding.

[0047] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0048] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
