Technical Field
[0001] This utility model relates to the field of dishwasher technology, and more specifically, to a rubber band conveying device. Background Technology
[0002] Rubber band conveyor belts are a common material handling device widely used in tableware and other item conveying systems in the catering and food processing industries. Their basic working principle involves a motor driving a transmission shaft, which in turn rotates a wheel on the shaft. The friction between the wheel and the rubber band causes the ring-shaped rubber band to rotate continuously, thus achieving the horizontal conveying of plates, tableware, and other items placed on it.
[0003] In practical applications, especially during peak dining hours when the volume of tableware being transported is high, this conveyor system reveals a significant technical flaw: when plates enter the turning section of the conveyor belt at high density, due to the physical limitations of the turning mechanism and the interaction between the plates, the plates are prone to accumulating and colliding at the turning point, leading to a "plate jamming" phenomenon. That is, the plates get stuck at the turning point and cannot pass smoothly, causing a blockage in the conveyor line. This not only interrupts the normal conveying process and reduces transportation efficiency, requiring manual intervention to clear the blockage, but also poses a safety risk of plates tipping over and tableware damage.
[0004] To address the aforementioned problems, existing technologies typically employ solutions such as optimizing turning radii, adding guide rails, or using intermittent start-stop control. However, these methods all have limitations: optimizing turning radii and adding guide rails are constrained by installation space and cost, often resulting in limited effectiveness; while intermittent start-stop control significantly reduces overall conveying efficiency, failing to meet the demands of continuous, efficient operation during peak periods. Therefore, how to effectively solve the problem of tray accumulation and jamming at turns without sacrificing efficiency has become a pressing technical challenge in this field. Utility Model Content
[0005] To overcome at least one of the defects in the prior art, this utility model provides a rubber band conveying device that can effectively solve the problem of food trays accumulating and getting stuck at bends.
[0006] The technical solution adopted by this utility model is as follows: a rubber band conveying device is provided, including a right-angled frame. A first rubber band conveyor belt and a second rubber band conveyor belt are provided on the upper end of the frame. One end of the first rubber band conveyor belt is connected to the left end of the first right-angled side frame of the frame, and the other end is connected to the right end of the first right-angled side frame. One end of the second rubber band conveyor belt is connected to the rear end of the second right-angled side frame of the frame, and the other end is connected to the right end of the first right-angled side frame and is close to the first rubber band conveyor belt, so that the plates on the first rubber band conveyor belt can be conveyed to the second rubber band conveyor belt, and the running speed of the first rubber band conveyor belt is less than the running speed of the second rubber band conveyor belt.
[0007] Compared with the prior art, the rubber band conveying device of this utility model has the following advantages: In the structure of this utility model's elastic band conveyor device, the elastic bands are arranged sequentially and operate independently along the direction of plate conveying on the same conveyor frame. By controlling the running speed of the first elastic band conveyor belt and the second elastic band conveyor belt, when the plate enters the middle corner frame from the first right-angle side frame position at a low speed, the plate conveying speed is accelerated under the action of the second elastic band conveyor belt, thereby increasing the spacing between the plates and effectively solving the problem of plates piling up at the corner position.
[0008] Furthermore, the first rubber band conveyor belt includes a first driving wheel, a first driven wheel, a first rubber band, and a first motor. The first driving wheel and the first driven wheel are respectively disposed at both ends of the first right-angled frame. The first motor is connected to the first driving wheel in a transmission manner, and the first rubber band is mounted on the first driving wheel and the first driven wheel.
[0009] Furthermore, the second rubber band conveyor belt includes a second driving wheel, a second driven wheel, a second rubber band, and a second motor. The second driving wheel is located at the right end of the first right-angled frame or the rear end of the second right-angled frame. Correspondingly, the second driven wheel is located at the rear end of the second right-angled frame or the right end of the first right-angled frame. The second motor is connected to the second driving wheel, and the second rubber band is mounted on the second driving wheel and the second driven wheel.
[0010] Preferably, there are four elastic bands in both the first and second types. The upper right end of the first right-angled frame is provided with a first rotating shaft, a middle rotating shaft, and a second fixed shaft in sequence along the tray conveying direction. The first motor is used to drive the first rotating shaft and the middle rotating shaft to rotate synchronously. The first driving wheel includes two inner driving wheels and two outer driving wheels located on the inner side. The two outer driving wheels are fixedly connected to the first rotating shaft, and the two inner driving wheels are fixedly connected to the middle rotating shaft. The second driven wheel includes two outer driven wheels and two inner driven wheels. The two outer driven wheels are rotatably connected to the middle rotating shaft, and the two inner driven wheels are rotatably connected to the second fixed shaft.
[0011] As an improvement, the first motor is located at the lower right end of the first right-angled frame, and the first motor is connected to the first rotating shaft via a first transmission assembly, and the first rotating shaft is connected to the intermediate rotating shaft via a second transmission assembly; a first fixed shaft is provided at the upper left end of the first right-angled frame, and four first driven wheels are rotatably connected to the first fixed shaft.
[0012] In a further improvement, the second motor is located at the lower part of the rear end of the second right-angled side frame, and a second rotating shaft is provided at the upper part of the rear end of the second right-angled side frame. Four second drive wheels are fixedly connected to the second rotating shaft, and the second motor and the second rotating shaft are connected by a third transmission assembly.
[0013] In a further improvement, the frame is equipped with a control box, which contains two frequency converters that are electrically connected to the first motor and the second motor, respectively.
[0014] Other improvements and advantages of this invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and drawings. Attached Figure Description

[0017] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0018] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "fixed" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0019] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0020] See Figures 1-6As shown in the illustration, this application discloses a rubber band conveying device, including a frame 1. A first rubber band conveyor belt and a second rubber band conveyor belt are provided on the upper end of the frame 1. One end of the first rubber band conveyor belt is connected to the left end of a first right-angled side frame 101, and the other end is connected to the right end of the first right-angled side frame 101. One end of the second rubber band conveyor belt is connected to the rear end of a second right-angled side frame 102, and the other end is connected to the right end of the first right-angled side frame 101 and is close to the first rubber band conveyor belt. This allows the plates on the first rubber band conveyor belt to be conveyed onto the second rubber band conveyor belt, achieving continuous conveying of the plates. The operating speed of the first rubber band conveyor belt is less than that of the second rubber band conveyor belt. With this configuration, by controlling the operating speeds of the first and second rubber band conveyor belts, the conveying speed of the plates increases when they enter the middle corner frame 103 from the position of the first right-angled side frame 101, thereby increasing the spacing between the plates and effectively solving the problem of plates piling up at the corner.
[0021] In this embodiment, specifically, the first rubber band conveyor belt includes a first driving wheel 2, a first driven wheel 3, a first rubber band 4, and a first motor 5. The first driving wheel 2 and the first driven wheel 3 are respectively located at both ends of the first right-angled side frame 101. That is, under normal circumstances, the positions of the first driving wheel 2 and the first driven wheel 3 on the first right-angled side frame 101 can be interchanged. The first motor 5 is connected to the first driving wheel 2 for transmission. The first rubber band 4 is fitted on the first driving wheel 2 and the first driven wheel 3. The position of the first motor 5 is not limited here, as long as it can drive the first driving wheel 2 to rotate. The specific transmission structure is described in detail below.
[0022] Similarly, the second rubber band conveyor belt includes a second driving wheel 6, a second driven wheel 7, a second rubber band 8, and a second motor 9. The second driving wheel 6 is located at the right end of the first right-angled side frame 101, and the second driven wheel 7 is located at the rear end of the second right-angled side frame 102. The second motor 9 is connected to the second driving wheel 6 for transmission. The second rubber band 8 is mounted on the second driving wheel 6 and the second driven wheel 7. In this structure, the positions of the second driving wheel 6 and the second driven wheel 7 can also be interchanged, that is, the second driving wheel 6 can be located at the rear end of the second right-angled side frame 102, and the second driven wheel 7 can be located at the right end of the first right-angled side frame 101. The position of the second motor 9 is not limited here, as long as it can drive the second driving wheel 6 to rotate. The specific transmission structure is described in detail below.
[0023] In this embodiment, as a preferred structure, there are four first elastic bands 4 and four second elastic bands 8, and the four first elastic bands 4 and the four second elastic bands 8 are located on the same straight line in the direction of plate conveying, and the interval between adjacent ones is also the same. The upper right end of the first right-angled side frame 101 is provided with a first rotating shaft 10, an intermediate rotating shaft 11, and a second fixed shaft 12 in sequence along the tray conveying direction. The first motor 5 is used to drive the first rotating shaft 10 and the intermediate rotating shaft 11 to rotate synchronously. The first driving wheel 2 includes two first inner driving wheels 201 and two first outer driving wheels 202 located on the inner side. The two first outer driving wheels 202 are fixedly connected to the first rotating shaft 10, and the two first inner driving wheels 201 are fixedly connected to the intermediate rotating shaft 11. The second driven wheel 7 includes two second outer driven wheels 701 and two second inner driven wheels 702. The two second outer driven wheels 701 are rotatably connected to the intermediate rotating shaft 11, and the two second inner driven wheels 702 are rotatably connected to the second fixed shaft 12. In addition, the two first outer driving wheels 202 are close to the two second outer driven wheels 701, and the two first inner driving wheels 201 and the two second inner driven wheels 702 are close to each other. That is, the two first inner driving wheels and the two second outer driven wheels 701 are aligned in the same straight line in the width direction of the frame 1, so that the first rubber band conveyor belt and the second rubber band conveyor belt remain continuous in the direction of plate conveying without interruption, thereby ensuring that the plate can be smoothly and continuously conveyed from the first rubber band 4 to the second rubber band 8 without plate jamming, thus avoiding plate accumulation.
[0024] For others, see Appendix Figure 5 The first motor 5 is mounted on the mounting base plate at the lower right end of the first right-angle side frame 101, and the first motor 5 is connected to the first rotating shaft 10 through the first transmission assembly 13. The first rotating shaft 10 is connected to the intermediate rotating shaft 11 through the second transmission assembly 14. The upper left end of the first right-angle side frame 101 is provided with a first fixed shaft 15, and four first driven wheels are rotatably connected to the first fixed shaft 15.
[0025] See appendix Figure 6 The second motor 9 is mounted on the mounting base plate at the lower part of the rear end of the second right-angled frame 102. The upper part of the rear end of the second right-angled frame 102 is provided with a second rotating shaft 16. Four second drive wheels 6 are fixedly connected to the second rotating shaft 16, and the second motor 9 and the second rotating shaft 16 are connected by a third transmission assembly 17.
[0026] The first transmission component 13, the second transmission component 14 and the structure of the first transmission component 13 mentioned above are conventional transmission structures, including a driving sprocket, a driven sprocket and a chain, with the chain fitting outside the driving sprocket and the driven sprocket.
[0027] In some other embodiments, the various transmission components may also consist of pulleys and transmission belts.
[0028] More specifically, in this embodiment, a control box 18 is provided on the frame 1, and the control box 18 contains two frequency converters that are electrically connected to the first motor 5 and the second motor 9, respectively. By adjusting the running speed of the first motor 5 and the second motor 9 through the two frequency converters, the speed difference between the first and second rubber band conveyor belts can be accurately controlled, thereby preventing the plates from accumulating and jamming during the conveying process.
[0029] In addition, the right-angled frame 1 involved in this embodiment includes a first right-angled side frame 101, a second right-angled side frame 102 and a middle corner frame 103. These can be an integral structure or a modular assembly structure.
[0030] In this embodiment, the first right-angled frame 101, the second right-angled frame 102, and the middle corner frame 103 are three independent modular frames. This means the three modular frames can be packaged and transported individually, effectively reducing packaging volume and transportation costs. On-site assembly by the user is very convenient. For more details, please refer to the appendix. Figure 1 and 3 A separate linear mounting frame 104 is provided at one end of the first right-angle frame 101 near the middle corner frame 103. The first motor 5, the first rotating shaft 10, the middle rotating shaft 11 and the second fixed shaft 12 are all mounted on the mounting frame 104, which makes it more convenient for the production and assembly of the modular frame structure.
