[0029] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0030] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0031] Please refer to Figure 1 and Figure 4 As shown, one embodiment of this disclosure provides a commercial dishwasher with an adjustment mechanism. This commercial dishwasher can be used in restaurants, hotels, and company canteens, etc. It includes a frame 1 and a transmission assembly. The transmission assembly includes a mounting rod 12 and two rotating wheels 4. The two rotating wheels 4 are respectively mounted on both ends of the mounting rod 12, which is set on the frame 1. The rotating wheels 4 pass through the mounting rod 12 and rotate around it. A conveyor belt 3 is provided on the frame 1. The rotation of the rotating wheels 4 drives the movement of the conveyor belt 3. Adjusting nuts 10 are provided on both ends of the mounting rod 12. The adjusting nuts 10 are used to adjust the tension of the conveyor belt 3. When the tension of the conveyor belt 3 is not appropriate, the tension of the conveyor belt 3 can be adjusted by adjusting the adjusting nuts 10, which is convenient and quick, and the maintenance cost of the adjusting nuts 10 is low. In addition, since the adjusting nuts 10 are provided on both ends of the mounting rod 12, the tension of both ends of the conveyor belt 3 can be adjusted synchronously. This makes the force on both sides of the conveyor belt 3 more balanced when adjusting the adjusting nuts 10, effectively preventing the tableware from tipping over and slipping.

[0032] Please refer to the following: Figure 2 , Figure 3 and Figure 6As shown, in one embodiment of this disclosure, the frame 1 is provided with a first mounting hole, and the mounting rod 12 is provided with a second mounting hole 15. The adjusting nut 10 passes through the first mounting hole and the second mounting hole 15. Preferably, the first mounting hole and the second mounting hole 15 are set at the same height, so that the adjusting nut 10 can always be kept horizontal, making the working stability of the adjusting nut 10 better. The frame 1 includes a first mounting plate 5, which is set perpendicular to the direction of movement of the conveyor belt 3. The first mounting hole is set on the first mounting plate 5. The setting of the first mounting plate 5 makes it easier to install and adjust the adjusting nut 10. The first mounting plate 5 is connected to the frame 1 body by bolts. Frequent adjustment of the adjusting nut 10 will inevitably cause wear to the first mounting hole. Only the first mounting plate 5 needs to be replaced. That is, the setting of the first mounting plate 5 saves the later maintenance cost to a certain extent. Preferably, the frame 1 includes an inlet end and an outlet end 2. The tableware enters the dishwasher from the inlet end and leaves from the outlet end 2 after washing. The adjusting nut 10 is set at the outlet end 2. One end of the adjusting nut 10 is provided with an external thread, and the inner circumferential wall of the second mounting hole 15 is provided with an internal thread. The external thread and the internal thread are screwed together to adjust the tension of the conveyor belt 3.

[0033] Please continue reading. Figures 2-4 As shown, the frame 1 also includes a second mounting plate 6, which is parallel to the first mounting plate 5. A third mounting plate 7 and a fourth mounting plate 9, parallel to each other, are positioned between the first mounting plate 5 and the second mounting plate 6. The third mounting plate 7 is positioned above the fourth mounting plate 9, and an adjusting nut 10 is positioned between the third mounting plate 7 and the fourth mounting plate 9. The third mounting plate 7 and the fourth mounting plate 9 form a limiting groove, and the end of the mounting rod 12 is located in the limiting groove. The third mounting plate 7 is located above the mounting rod 12, and the fourth mounting plate 9 is located below the mounting rod 12. The third mounting plate 7 and the fourth mounting plate 9 limit the mounting rod 12 at its upper and lower positions, respectively, preventing the mounting rod 12 from tilting upwards or downwards under the force of the tableware during operation, thus making the dishwasher more stable when conveying tableware. Preferably, the third mounting plate 7 and the fourth mounting plate 9 are detachably connected to the first mounting plate 5 and the second mounting plate 6, respectively, for example, by bolts. This allows for individual replacement of the first mounting plate 5, the second mounting plate 6, the third mounting plate 7, or the fourth mounting plate 9, reducing maintenance costs.

[0034] like Figure 5 and Figure 6As shown, it should be noted that the middle part of the mounting rod 12 is a cylindrical structure, and both ends of the mounting rod 12 are respectively provided with recessed structures 14, and the second mounting hole 15 is provided on the recessed structure 14. The recessed structure 14 makes it less likely for the mounting rod 12 to roll in the limiting groove, thus making it more stable and reliable during operation; at the same time, the recessed structure 14 provides more operating space when turning the adjusting nut 10, making operation more convenient.

[0035] To ensure more stable operation of the conveyor belt 3, limit rings 13 are installed on both sides of the rotating wheel 4, with the limit rings 13 passing through the mounting rod 12. The limit rings 13 are used to limit the horizontal movement of the rotating wheel 4, preventing it from shifting horizontally during rotation around the mounting rod 12, which would disrupt the force balance on the conveyor belt 3 and affect its normal operation.

[0036] Please refer to Figure 1 and Figure 7 As shown, the conveyor belt 3 further includes a first area and a second area. The area of ​​the first area is larger than that of the second area. The first area is provided with a limiting protrusion 8, which is used to limit the movement of tableware. The first area is used to place tableware one, and the second area is used to place tableware two. Tableware one includes plates, bowls, dishes, etc.; tableware two includes spoons, chopsticks, forks, etc. Since tableware one is larger in size than tableware two, it needs to occupy a larger area. Preferably, the limiting protrusion 8 includes a first protrusion 16 and a second protrusion 17. The height of the first protrusion 16 is greater than that of the second protrusion 17. A groove 18 is formed between the first protrusion 16 and the second protrusion 17. The inner wall of the groove 18 is rounded and smooth. This design can prevent the tableware from being worn during the conveying process, and the limiting protrusion 8 can play a good role in fixing both round and square plates. The first protrusion 16 and the second protrusion 17 can be rod-shaped or block-shaped, and can be regular or irregular in shape. No specific restrictions are made here, and the appropriate shape is selected according to the actual situation. Plates and other tableware are held in the groove 18. The first protrusion 16 mainly serves as a limit, while the second protrusion 17 serves both a limit and a support, keeping the plates upright in the groove 18. This allows for a wider cleaning area when washing the tableware. The wastewater and dirt on the tableware flow directly downwards due to gravity, leaving almost no blind spots in the cleaning process. This makes the dishwasher's cleaning of tableware more convenient and thorough.

[0037] Please refer to Figure 2 and Figure 3As shown in one embodiment of this disclosure, the first mounting plate 5 is further provided with a third mounting hole 11 and a locking nut. The third mounting hole 11 is at the same horizontal height as the first mounting hole. One end of the locking nut is disposed in the third mounting hole 11, and the other end of the locking nut abuts against the mounting rod 12. During operation, the rotation of the rotating wheel 4 and the movement of the conveyor belt 3 cause vibration in the frame 1. Furthermore, the large number of dishes on the conveyor belt 3 results in significant pressure on the conveyor belt 3, further aggravating the vibration of the frame 1. Over time, the vibration of the frame 1, the rotation of the rotating wheel 4, and the movement of the conveyor belt 3 can easily cause the adjusting nut 10 to loosen. This necessitates frequent observation and adjustment of the adjusting nut 10 by the operator, increasing their workload. By abutting the locking nut against the mounting rod 12, an additional force is applied to the mounting rod 12, making the adjusting nut 10 less prone to loosening and further reducing the operator's workload.

[0038] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
