Description

Technical Field

[0001] This disclosure relates to the field of commercial dishwasher technology, and in particular to a limiting mechanism for a commercial dishwasher conveyor belt. Background Technology

[0002] With economic development and social progress, dishwashers are gradually becoming more intelligent. Using a dishwasher saves personal time, as it has strong cleaning power and can thoroughly eliminate bacteria on the surface of tableware. Dishwashers are simple to operate yet powerful, meeting multiple needs such as washing, drying, and sterilization, providing great convenience to people's daily lives. Nowadays, people use dishwashers more and more frequently. Dishwashers can be categorized by purpose into commercial and household dishwashers. Commercial dishwashers are generally used in hotels, restaurants, and similar establishments, while household dishwashers are only suitable for homes and mainly come in two types: cabinet and countertop.

[0003] Most commercial dishwashers have a conveyor belt, on which dishes to be washed are placed directly and then transported to the washing area. Patent No. 201921542869.3 discloses a long-line automatic dishwasher, including a loading platform, a soaking tank, an ultrasonic cleaning tank, a conveyor belt, and a storage cabinet arranged in a straight line. The conveyor belt is equipped with a receiving station, a spraying station, a drying station, a visual inspection station, and an unloading station. A transfer tray is placed on the loading platform. Robotic arms for moving the transfer tray are installed between the loading platform and the soaking tank, between the soaking tank and the ultrasonic cleaning tank, between the ultrasonic cleaning tank and the receiving station, and between the unloading station and the storage cabinet. The spraying station is equipped with a high-temperature spray box, the drying station is equipped with an air drying box, and the visual inspection station is equipped with an industrial camera. When unloading tableware from a conveyor belt, it often requires the assistance of a robotic arm or manual labor to transfer the tableware to another area. If the robotic arm or manual labor cannot transfer the tableware at the end of the conveyor belt in time, the tableware will continue to move in the direction the conveyor belt is running and eventually fall off the conveyor belt. This causes some inconvenience to users and may even cause some economic losses due to the tableware falling off. Utility Model Content

[0004] In view of the shortcomings or problems existing in the prior art, this disclosure provides a limiting mechanism for the conveyor belt of a commercial dishwasher, which can effectively prevent tableware from falling off the end of the conveyor belt.

[0005] The technical solution adopted by this disclosure to solve the above-mentioned technical problem is: a limiting mechanism for a commercial dishwasher conveyor belt, comprising:

[0006] Connection component, used to connect to the dishwasher body;

[0007] A sensing component is disposed on the connecting component. The sensing component is connected to a controller and is used to sense whether the counterweight assembly is moving.

[0008] The limiting component includes a mounting rod and a blocking member, the blocking member being disposed on the mounting rod, and the mounting rod being rotatably connected to the connecting component;

[0009] The counterweight assembly is mounted on the mounting rod. When the tableware touches the blocking component, the blocking component causes the mounting rod and the counterweight assembly to move together.

[0010] In a preferred embodiment, the connecting assembly is disposed at the end of the conveyor belt. The connecting assembly includes a first connecting block and a second connecting block disposed opposite to each other. The two ends of the mounting rod are respectively connected to the first connecting block and the second connecting block, and the blocking member is located between the first connecting block and the second connecting block.

[0011] In a preferred embodiment, a first connecting shaft is provided on the inner side of the first connecting block, and a second connecting shaft is provided on the inner side of the second connecting block. The first connecting shaft and the second connecting shaft are on the same axis. First mounting holes are provided at both ends of the mounting rod. The first connecting shaft and the second connecting shaft are at least partially located in the first mounting holes. The mounting rod can rotate around the axis where the first connecting shaft and the second connecting shaft are located.

[0012] In a preferred embodiment, the sensing component is a position sensor, and the sensing component is provided on the inner side of both the first connecting block and the second connecting block. The sensing component is signal-connected or electrically connected to the controller.

[0013] In a preferred embodiment, the counterweight assembly includes a first counterweight and a second counterweight, wherein the first counterweight is disposed inside the first connecting block and the second counterweight is disposed inside the second connecting block.

[0014] In a preferred embodiment, the first connecting block is provided with a first limiting protrusion, which is located on the side of the first counterweight and is used to limit the first counterweight to keep it in a vertical state; the second connecting block is provided with a second limiting protrusion, which is located on the side of the second counterweight and is used to limit the second counterweight to keep it in a vertical state.

[0015] In a preferred embodiment, a first connecting frame and a second connecting frame are detachably connected to the mounting rod. The first counterweight is disposed on the first connecting frame, and the second counterweight is disposed on the second connecting frame. When the mounting rod rotates, the first connecting frame and the second connecting frame move together.

[0016] In a preferred embodiment, the mounting rod is a hollow structure, comprising a first housing and a second housing that overlap each other, and a first connecting frame and a second connecting frame connected to the first housing.

[0017] Compared to existing products, when the tableware at the end of the conveyor belt hits the blocking component, the blocking component moves the mounting rod and counterweight assembly together. The sensing component detects the movement of the counterweight and transmits a signal to the controller. The controller then controls the conveyor belt to stop moving. This prevents the tableware at the end of the conveyor belt from falling off when the robotic arm or manual labor cannot transfer it in time, making the commercial dishwasher safer during operation.

[0027] 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.

[0028] 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.

[0029] like Figure 1 As shown, this disclosure provides a limiting mechanism for the conveyor belt of a commercial dishwasher, including: a connecting component for connecting the dishwasher body; a sensing component disposed on the connecting component, connected to a controller, and used to sense whether a counterweight assembly is moving; a limiting component including a mounting rod 3 and a blocking member 4, the blocking member 4 being disposed on the mounting rod 3 and rotatably connected to the connecting component; and a counterweight assembly disposed on the mounting rod 3. When tableware hits the blocking member 4, the blocking member 4 causes the mounting rod 3 and the counterweight assembly to move together. When tableware at the end of the conveyor belt hits the blocking member 4, the blocking member 4 causes the mounting rod 3 and the counterweight assembly to move together. The sensing component senses the movement of the counterweight and transmits a signal to the controller, which then controls the conveyor belt to stop moving. This prevents tableware at the end of the conveyor belt from falling when the robotic arm or manual operator cannot transfer it in time, making the commercial dishwasher safer during operation.

[0030] Please refer to Figures 4-6As shown, further, a connecting assembly is disposed at the end of the conveyor belt. The connecting assembly includes a first connecting block 1 and a second connecting block 2 disposed opposite to each other. The outer sides of the first connecting block 1 and the second connecting block 2 are connected to the dishwasher body. The two ends of the mounting rod 3 are respectively connected to the first connecting block 1 and the second connecting block 2. The blocking member 4 is located between the first connecting block 1 and the second connecting block 2. Specifically, a first connecting shaft 13 is disposed on the inner side of the first connecting block 1, and a second connecting shaft 14 is disposed on the inner side of the second connecting block 2. The first connecting shaft 13 and the second connecting shaft 14 are on the same axis. The two ends of the mounting rod 3 are provided with first mounting holes. The first connecting shaft 13 and the second connecting shaft 14 are at least partially located in the first mounting holes. The mounting rod 3 can rotate around the axis on which the first connecting shaft 13 and the second connecting shaft 14 are located. When the tableware at the end of the conveyor belt hits the blocking member 4, it causes the mounting rod 3 to rotate around the axis on which the first connecting shaft 13 and the second connecting shaft 14 are located.

[0031] like Figure 1 As shown, in one embodiment of this disclosure, the counterweight assembly includes a first counterweight 11 and a second counterweight 12. The first counterweight 11 is disposed inside the first connecting block 1, and the second counterweight 12 is disposed inside the second connecting block 2. The first counterweight 11 and the second counterweight 12 are cement blocks or iron blocks. The sensing component is a position sensor. Sensing components are disposed inside both the first connecting block 1 and the second connecting block 2 to sense whether the first counterweight 11 and the second counterweight 12 are moving (the tableware hits the blocking part 4, and the mounting rod 3 drives the breeding component to move together). The sensing components are signal-connected or electrically connected to the controller. If one of the sensing components senses the movement of the breeding component, the controller will control the conveyor belt to stop moving, thus avoiding the situation where the tableware falls because the controller fails to stop the conveyor belt in time due to the insensitivity or damage of one of the sensing components.

[0032] Please refer to Figures 2-6As shown, the counterweight assembly may sometimes move for other reasons. The sensing component detects the movement of the counterweight assembly and transmits the signal to the controller. The controller then stops the conveyor belt. However, in this case, the movement of the counterweight assembly is not due to the accumulation of tableware. If the conveyor belt stops running, the commercial dishwasher will not operate normally, affecting work efficiency. To avoid the above situation, the first connecting block 1 is provided with a first limiting protrusion 15, which is located on the side of the first counterweight 11. The first limiting protrusion 15 is used to keep the first counterweight 11 in a vertical state. The second connecting block 2 is provided with a second limiting protrusion 16, which is located on the side of the second counterweight 12. The second limiting protrusion 16 is used to keep the second counterweight 12 in a vertical state. The first limiting protrusion 15 and the second limiting protrusion 16 are columnar or block-shaped. The first limiting protrusion 15 and the second limiting protrusion 16 respectively limit the first counterweight 11 and the second counterweight 12, thereby preventing the breeding component from moving due to other reasons (the movement of the breeding component is not driven by the mounting rod 3), such as accidental collision when a person passes by. In other words, the first limiting protrusion 15 and the second limiting protrusion 16 can reduce the occurrence of the counterweight component moving due to other reasons.

[0033] Please continue reading. Figures 1-3 As shown, preferably, the mounting rod 3 is detachably connected to a first connecting frame 5 and a second connecting frame 6. A first counterweight 11 is disposed on the first connecting frame 5, and a second counterweight 12 is disposed on the second connecting frame 6. When the mounting rod 3 rotates, the first connecting frame 5 and the second connecting frame 6 move together. Specifically, the first connecting frame 5 and the second connecting frame 6 are roughly L-shaped structures. The first connecting frame 5 includes an integrally formed first plate 9 and a second plate 10. The first counterweight 11 is disposed on the first plate 9, and the second plate 10 is connected to the mounting rod 3 by bolts. A gap is provided between the first plate 9 and the first connecting block 1. The gap is provided to prevent friction between the first connecting frame 5 and the first connecting block 1 when the mounting rod 3 rotates, so that as soon as the tableware hits the blocking part 4, the mounting rod 3 can drive the first connecting frame 5 and the first counterweight 11 on the first connecting frame 5 to move together, thus making the movement of the first counterweight 11 more sensitive. The second connecting frame 6 includes an integrally formed third plate and a fourth plate. The fourth plate is connected to the mounting rod 3 by bolts. The second counterweight 12 is set on the third plate. There is a gap between the third plate and the second connecting block 2. The gap prevents the second connecting frame 6 from rubbing against the second connecting block 2 when it rotates with the mounting rod 3. This allows the mounting rod 3 to drive the second connecting frame 6 and the second counterweight 12 on the second connecting frame 6 to move together as soon as the tableware hits the blocking part 4, making the movement of the second counterweight 12 more sensitive.

[0034] In one embodiment of this disclosure, the mounting rod 3 is a hollow, straight-line structure. The mounting rod 3 includes a first housing and a second housing that overlap each other. The first connecting frame 5 and the second connecting frame 6 are connected to the first housing. The blocking member 4 includes a U-shaped frame 7. A plurality of rods 8 are arranged in parallel on the frame 7. The opening of the frame 7 faces the mounting rod 3. The two ends of the frame 7 and the rods 8 on the frame 7 are connected to the mounting rod 3.

[0035] 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.
