Description

Technical Field

[0001] This utility model belongs to the technical field of restaurant supplies, and in particular relates to a stable plate-moving device. Background Technology

[0002] To make it easier for people to pick up the food they want and to prevent food from being dropped on the table when they get up, many larger dining tables have internal transmission mechanisms that automatically drive the plates. These mechanisms include intelligent conveyor belt systems, robotic systems, and even electromagnetic drive systems. Some high-end dining tables even have interactive touchscreens on the table for selecting desired dishes. Additionally, some tables, such as those designed for rotating hot pots, use chains to move the plates.

[0003] The aforementioned dining tables generally have a built-in tray-moving mechanism, making them more suitable for restaurant use and less suitable for home use. Home dining tables are generally divided into round and square tables, with square tables further divided into rectangular or octagonal tables. Round and octagonal tables can use a rotating tray (on which all plates containing food are placed) to move the plates. However, due to their length, even with a rotating tray, it's difficult to reach food from the ends of a rectangular table. Furthermore, tables resembling rotating hot pot tables are also unsuitable for home use due to their high cost and high repair costs after malfunction.

[0004] To address the aforementioned technical issues, I applied for a Chinese utility model patent on May 16, 2025, entitled "A Plate Moving Device Suitable for Rectangular Tables," with application number 202520970372.0. However, in large business and hotel banquets, the table size is large due to the number of people, and the number of plates is correspondingly large. Under these conditions, the power output of the patented product during use is insufficient to move all the plates along the base. Therefore, the product is only suitable for use in households where the required plates are relatively small. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a stable plate-moving device suitable for large-scale banquets requiring large dining tables and numerous plates.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a stable plate-moving device, comprising:

[0007] The base has a racetrack-shaped extension path and is designed to be placed on top of a long rectangular table.

[0008] Multiple sliders, all of which are slidably mounted on the base;

[0009] A belt conveyor mechanism is placed above a long rectangular table, and the belt conveyor mechanism is provided with a connecting component for connecting and driving the slider to move along the extension path of the base.

[0010] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0011] Preferably, the belt conveyor mechanism includes:

[0012] At least two drive discs, with a conveyor belt connecting adjacent drive discs;

[0013] A drive motor is provided above any of the transmission discs, and the drive motor is mounted on the motor mounting bracket. The drive end of the drive motor is connected to the transmission disc.

[0014] Preferably, the conveyor belt is provided with a plurality of connecting seats along its transmission direction, one end of the connecting assembly is fixed on the connecting seat, and the other end is connected to the slider.

[0015] Preferably, the connecting assembly includes a connecting rod, one end of which is fixed to the connecting seat, and the end of the connecting rod away from the connecting seat has a locking end. A limiting groove is formed on one side of the slider, and the locking end and the limiting groove are interference-fitted.

[0016] Preferably, the base includes a bottom plate and two upper blocks arranged at intervals above the bottom plate. The slider includes a support plate and two bearing assemblies arranged at intervals below the support plate. The bearing assemblies are used to slide and connect with the upper blocks, and include at least one bearing.

[0017] Preferably, the plate rotating device further includes a slide rail assembly, the slide rail assembly comprising:

[0018] The inner sliding rail extends in a racetrack shape;

[0019] The outer slide rail extends in a racetrack shape and is arranged around the inner slide rail;

[0020] The upper connecting block is snapped onto the inner side of the inner slide rail and the outer slide rail, and the bearing is slidably installed on the outer side of the inner slide rail and the outer slide rail.

[0021] Preferably, the outer side of the upper connecting block is provided with an outwardly extending convex slide rail or an inwardly recessed slide rail, and the bearing is slidably mounted on the convex slide rail or the inwardly recessed slide rail.

[0022] Preferably, at least one ball bearing seat is installed below the support plate, and the lower end of the ball bearing seat abuts against the top of the bottom plate.

[0023] Through the above technical solution, compared with the prior art, this utility model has the following beneficial effects: Since the extension path of the base is racetrack-shaped, it can be adapted to be placed above a long rectangular table. Simultaneously, the belt conveyor mechanism is placed in the central area above the table, enclosed by the racetrack-shaped base. The belt conveyor mechanism includes two transmission discs that can rotate on the long rectangular table, a conveyor belt connecting the two transmission discs, and a drive motor connected to one of the transmission discs. When power is supplied to the drive motor, the drive motor operates and drives the transmission disc connected to its drive end to rotate, causing the conveyor belt to move between the two transmission discs. Because the conveyor belt moves between the two transmission discs via the connecting assembly and the base... The slider is fixedly connected, so when the conveyor belt is driven, the slider moves along the extension direction of the conveyor belt (which is also a racetrack-shaped extension path), thereby driving the plate placed above the slider to move along the racetrack-shaped extension path. By using the drive motor in combination with the transmission disc and the conveyor belt, the transmission efficiency is greatly improved, and the power required to drive the slider is further increased. Even in large-scale banquets, all plates can be driven at the same time without insufficient power causing the slider to stop moving. This solves the technical problem that the current household plate moving device outputs insufficient power, making it unsuitable for large banquets with many plates. Attached Figure Description

[0040] The following will refer to the appendix in the embodiments of this utility model. Figure 1-12 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0041] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0042] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0043] Detailed implementation plan: See below Figures 1-12 As shown: A device for driving and stabilizing a moving plate, comprising:

[0044] Base 1, the extension path of base 1 is racetrack shaped, and it is suitable for placement on a long rectangular table;

[0045] Multiple sliders 2 are slidably mounted on the base 1;

[0046] A belt conveyor mechanism is placed above a long rectangular table. The belt conveyor mechanism is equipped with a connecting component for connecting and driving the slider 2 to move along the extension path of the base 1.

[0047] Note that in this embodiment, the extension path of base 1 is designed as a racetrack shape, which can be adapted to be placed above a long rectangular table. In practical applications, regarding the extension path of base 1, the left and right ends of base 1 can be designed as a combination of curves and straight lines, and the straight lines can be adjusted according to the width of the long rectangular table. In practical applications, base 1 can be designed as multiple parts to be spliced ​​together (not shown in the figure). This facilitates transportation after disassembly and allows the length of the straight lines in the length and width directions to be adjusted according to the size of the long rectangular table.

[0048] As a preferred embodiment of this example, Figure 1-2 As shown: The belt conveyor mechanism includes: at least two drive discs 3, and a conveyor belt 4 is connected between adjacent drive discs 3;

[0049] A drive motor 5 is mounted on a motor mounting bracket 6 above any of the transmission discs 3. The drive end of the drive motor 5 is connected to the transmission disc 3.

[0050] In this embodiment, the transmission disc 3 can be a pulley, and the conveyor belt 4 can be a synchronous belt that matches the pulley. The two transmission discs 3 are arranged opposite each other on both sides of the central area of ​​the long rectangular table enclosed by the annular path of the base 1, respectively corresponding to the curved parts on both sides of the base 1. The shape formed by the two transmission discs 3 and the conveyor belt 4 corresponds to the shape enclosed by the extension of the base 1. In addition, the connecting component can be adjusted in length according to the distance between the base 1 and the belt conveyor mechanism.

[0051] It is important to note that during actual installation, the drive motor 5 needs to be fixed above the transmission disc 3 using a motor mounting bracket 6, with its drive end extending downwards and fixed to the drive hole on the transmission disc 3, thereby driving the transmission disc 3 to rotate. A transmission seat is located below the transmission disc 3, which can be placed on a table. The transmission disc 3 is rotatably mounted on the transmission seat, realizing the transmission action of the conveyor belt 4. In this embodiment, the drive motor 5 is equipped with a reducer and a controller. The controller is used to control the rotation speed of the drive motor 5. The user can also control whether the drive motor 5 is working and its working speed via a remote control. The use of a controller to control the drive motor 5 and the adjustment of torque by installing a reducer on the drive motor 5 are existing technologies and will not be elaborated upon here.

[0052] As a preferred embodiment of this example, Figure 1-2 As shown: The conveyor belt 4 is provided with a plurality of connecting seats 401 along its transmission direction. One end of the connecting component is fixed on the connecting seat 401, and the other end is connected to the slider 2. In this embodiment, the connecting seat 401 is fixed on the conveyor belt 4, and each connecting seat can correspond to a slider 2 to ensure that the two can move synchronously. In addition, each slider 2 is fixed to the connecting seat 401 on the conveyor belt 4 through the connecting component.

[0053] As a preferred embodiment of this example, Figure 1-2 As shown: The connecting assembly includes a connecting rod 9, one end of which is fixed to the connecting seat 401. The end of the connecting rod 9 away from the connecting seat 401 has a locking end. A limiting groove 20 is provided on one side of the slider 2. The locking end and the limiting groove 20 are interference-fitted. In this embodiment, the two are fixed to each other by the interference fit between the limiting groove 20 and the locking end. This connection method has strong stability. In addition, the connecting rod 9 and the slider 2 can also be fixed by detachable methods such as snap-fitting, bonding, threading, and magnetic attraction.

[0054] like Figure 4-6As shown: The base 1 includes a bottom plate 101 and two upper blocks 102 fixed above the bottom plate 101 and spaced apart. The slider 2 includes a support plate 201 and two bearing assemblies fixed below the support plate 201 and spaced apart. The bearing assemblies are used to cooperate with and slide with the upper blocks 102, and include at least one bearing 202.

[0055] like Figure 4-8 As shown: The plate rotating device also includes a slide rail assembly, which includes:

[0056] The inner slide rail 7 extends in a racetrack shape;

[0057] The outer slide rail 8 extends in a racetrack shape and is arranged around the inner slide rail 7;

[0058] The upper connecting block 102 is snapped onto the inner side of the inner slide rail 7 and the outer slide rail 8, and the bearing is slidably installed on the outer side of the inner slide rail 7 and the outer slide rail 8.

[0059] In this embodiment, the outer side of the upper connecting block 102 is provided with a slot, and the upper connecting block 102 is installed on the inner slide rail 7 through the slot.

[0060] The slide rail assembly mentioned above is an independent accessory. During the assembly process, the inner slide rail 7 and the outer slide rail 8 need to be snapped onto the outside of the two upper connecting blocks 102 respectively, and then the two bearing assemblies of the slider 2 are slidably installed on the inner slide rail 7 and the outer slide rail 8 respectively.

[0061] Note that both the inner slide rail 7 and the outer slide rail 8 have curved sections, and the arc angle of the curved section of the outer slide rail 8 is larger than that of the curved section of the inner slide rail 7. Therefore, to ensure that the slider 2 can slide smoothly along the extension direction of the slide rail assembly, please refer to [the relevant documentation / reference needed]. Figure 7 The distance between the two bearings in the outer bearing assembly needs to be greater than the distance between the two bearings in the inner bearing assembly.

[0062] In addition, such as Figure 9-10 As shown: In practical applications, an outwardly extending convex slide rail 124 can also be provided on the outer side of the upper connecting block 102 (without the slide rail assembly mentioned above), and the bearing is slidably mounted on the convex slide rail 124.

[0063] In fact, by setting the outer protruding slide rail 124 on the outside of the upper connecting block 102, its function is the same as that of the inner slide rail 7 and the outer slide rail 8 mentioned above, except that there is no need to install the inner slide rail 7 and the outer slide rail 8 on the base 1.

[0064] Note that the external convex slide rail 124 here, as well as the internal slide rail 7 and external slide rail 8 mentioned above, are all applicable to concave bearings.

[0065] Please see Figure 11In practical applications, an inwardly extending concave slide rail 125 can also be provided on the outer side of the upper connecting block 102. In this case, the bearing applicable to the concave slide rail 125 is an outwardly convex bearing.

[0066] In a preferred embodiment of this invention, at least one ball bearing seat is installed below the support plate 201, with the lower end of the ball bearing seat abutting against the top of the bottom plate 101. Here, by providing a ball bearing seat below the support plate 201, the upper load-bearing capacity of the support plate 201 can be increased, and the support plate 201 will not deform even if heavy plates and dishes are placed on top of it.

[0067] Additionally, a connector 11 may be provided between adjacent sliders 2. For more details, please refer to [link / reference]. Figure 12 The connector 11 includes a rotating disk 110 and two connecting rods. One end of the connecting rod is rotatably mounted on the slider 2, and the other end is rotatably mounted on the rotating disk 110.

[0068] In this embodiment, when the slider 2 passes through the curved area of ​​the base 1, one end of the connecting rod rotates relative to the slider 2, and the other end rotates relative to the rotating disk 110. Furthermore, the rotating disk 110 allows adjustment of the direction of the tension in the connecting member 11, facilitating easier cornering. The structural design and working principle of the connecting rod and rotating disk 110 are existing technologies, and similar applications exist in current rotating hot pot dining tables; therefore, they will not be discussed further here.

[0069] Please see Figure 5 As can be seen, the upper inner side of the upper connecting block 102 is provided with an inwardly extending baffle 123. The design of the baffle 123 is to limit the tilted end of the rotating disk 110 when it turns a bend, if one end of the rotating disk 110 tilts up.

[0070] The working principle and beneficial effects of the plate-moving device in this embodiment will be explained below. ：

[0071] After the power supply provides power to the drive motor 5, the drive motor 5 operates and drives the transmission disk 3 connected to its drive end to rotate, causing the conveyor belt 4 to move between the two transmission disks 3. Since the conveyor belt 4 is fixedly connected to the slider 2, which is movable on the base 1, when the conveyor belt 4 is driven, the slider 2 will move along the extension direction of the conveyor belt 4 (which is also a racetrack-shaped extension path), thereby driving the plate placed above the slider 2 to move along the racetrack-shaped extension path. Through the above-mentioned drive method of the drive motor 5 combined with the transmission disk 3 and the conveyor belt 4, the transmission efficiency is greatly improved, and the power required to drive the slider 2 to move is further increased. Even in large-scale banquets, all plates can be driven to move at the same time, and there will be no situation where the slider stops moving due to insufficient power. This solves the technical problem that the current household plate moving device outputs insufficient power, which makes it impossible to use in large banquets with a large number of plates.

[0072] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
