Description

Technical Field

[0001] This utility model relates to the technical field of driving devices, specifically to a pushing device and a hot food machine having the same. Background Technology

[0002] With the fast pace of life, the demand for convenient and quick access to hot food is increasing. Automatic food heating machines, as devices that can provide consumers with instant hot meals, are gradually gaining market attention and favor. However, existing automatic food heating machines have some limitations and shortcomings in their food dispensing methods.

[0003] Currently, the most common automatic hot food machines on the market mainly have the following two food dispensing methods:

[0004] 1. Manual Delivery Method: Refrigerated food needs to be manually removed from the refrigerated area and placed into the heating device for heating. After heating, the food is then manually removed and handed to the consumer. This method has many problems, such as low efficiency due to manual operation, susceptibility to operational errors, uneven heating of food, or delays in delivery. Furthermore, frequent manual handling may increase the risk of food contamination, failing to meet food safety and hygiene requirements.

[0005] 2. Automatic Drop Dispensing Method: Refrigerated food is automatically dropped from the refrigerated area into a heating unit for heating. After heating, the food automatically falls into a retrieval area located below the heating unit, where it is then picked up by the user. While this dispensing method reduces manual operation to some extent, it has also revealed some problems in actual use. For example, heated food may be bumped or squeezed during the drop process, affecting its shape and texture.

[0006] Therefore, the existing technology still needs further development. Utility Model Content

Therefore, by setting up the push plate, the heated food can be smoothly pushed into the dispensing compartment, preventing food from falling and reducing damage caused by collisions and compression. Meanwhile, the first detection mechanism monitors the pusher's travel in real time and controls the transmission mechanism's movement based on the detection results, ensuring accurate delivery of food to the dispensing compartment with each push, further reducing the risk of food damage. Furthermore, a feedback mechanism adjusts the transmission mechanism's action, ensuring the pusher moves along a predetermined path and distance, improving pushing accuracy and stability. The design of the first detection mechanism significantly reduces instances of incomplete or excessive pushing, enhancing system reliability and consistency.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] Please see Figures 1 to 6 According to an embodiment of the present invention, a pushing device is provided for pushing heated food within the heating device 100 into the dispensing compartment along the width direction of the heating device 100. The pushing device includes: a push plate 1, a transmission mechanism 2, and a first detection mechanism 3. The push plate 1 is movably disposed within the heating device 100 and is used to push the heated food into the dispensing compartment. The transmission mechanism 2 is movably disposed, and its output portion is connected to the push plate 1 to drive the push plate 1 to reciprocate along the width direction of the heating device 100. The first detection mechanism 3 is disposed on the side of the heating device 100 away from the dispensing compartment and is used to detect the travel distance of the push plate 1 towards the dispensing compartment. The first detection mechanism 3 is connected to the transmission mechanism 2 and controls the movement of the transmission mechanism 2 based on the detection result.

[0030] As can be seen, the pushing device provided by this utility model includes a push plate 1, a transmission mechanism 2, and a first detection mechanism 3. The push plate 1 is movably disposed within the heating device 100 along its width direction. The push plate 1 pushes the heated food from the heating device 100 into the dispensing compartment, facilitating the user to open the compartment door and remove the heated food. The transmission mechanism 2 is movably disposed and located on the side of the heating device 100 away from the dispensing compartment. The output of the transmission mechanism 2 passes through the side plate of the heating device 100 and connects to the push plate 1, thereby driving the push plate 1 to move. Furthermore, the first detection mechanism 3 is disposed on the outside of the heating device 100 and located on the side of the heating device 100 away from the dispensing compartment. The first detection mechanism 3 is connected to the transmission mechanism 2 and is used to detect the travel distance of the push plate 1 towards the dispensing compartment, thereby controlling the movement of the transmission mechanism 2 based on the detection result of the first detection mechanism 3. Therefore, by setting up pusher 1, heated food can be smoothly pushed into the delivery compartment, preventing food from falling and reducing damage caused by collisions and squeezing. Simultaneously, the first detection mechanism 3 monitors the stroke of pusher 1 in real time and controls the movement of transmission mechanism 2 based on the detection results, ensuring that each push accurately delivers food into the delivery compartment, further reducing the risk of food damage. Moreover, the feedback mechanism adjusts the action of transmission mechanism 2, ensuring that pusher 1 moves along a predetermined path and distance, improving the accuracy and stability of the push. Furthermore, the design of the first detection mechanism 3 significantly reduces instances of incomplete or excessive pushing, improving the reliability and consistency of the system. In addition, the connection between transmission mechanism 2 and the first detection mechanism 3 allows transmission mechanism 2 to quickly respond to signals from the first detection mechanism 3 and promptly change the direction of pusher 1's movement, improving the overall system's response speed. This pushing device achieves a high degree of automation in the entire pushing process, reducing manual intervention and improving system operating efficiency and reliability. Operators do not need to intervene frequently; the system can autonomously complete the food pushing task. The pushing device of this utility model can effectively solve the technical problem in the prior art that heated food may be damaged due to collision or squeezing when it falls from the heating device to the retrieval area in an automatic hot food machine.

[0031] Specifically, such as Figure 5 and Figure 6As shown, the transmission mechanism 2 has a contact plate 21, which reciprocates along the width direction of the heating device 100; the first detection mechanism 3 has a first trigger part 31, which is disposed opposite to the contact plate 21 of the transmission mechanism 2; wherein, the push plate 1 has an initial position for avoiding food and a dispensing position for pushing the heated food to the dispensing compartment. When the push plate 1 is in the initial position, the contact plate 21 and the first trigger part 31 are spaced apart; when the push plate 1 moves from the initial position toward the dispensing position, the contact plate 21 moves toward the first trigger part 31; when the push plate 1 moves to the dispensing position, the contact plate 21 abuts against the first trigger part 31, and the first detection mechanism 3 controls the transmission mechanism 2 to drive the push plate 1 to move away from the dispensing compartment, so that the push plate 1 returns to the initial position. With this structural arrangement, when the push plate 1 moves from the initial position toward the dispensing position, the contact plate 21 of the transmission mechanism 2 moves toward the first trigger part 31 of the first detection mechanism 3. This design ensures that the pusher 1 can stop accurately at the preset position (i.e., the shipping position), avoiding problems caused by insufficient or excessive pushing.

[0032] Among them, the width direction of the heating device 100 Figure 3 The direction indicated by arrow A in the middle.

[0033] Furthermore, the first testing agency 3 is the first limit switch.

[0034] Specifically, such as Figures 1 to 6 As shown, the pushing device also includes: a mounting frame 4, which is located on the side of the heating device 100 away from the shipping compartment, and is fixedly connected to the heating device 100; a transmission mechanism 2 is movably mounted on the mounting frame 4; and a first detection mechanism 3 is mounted on the mounting frame 4, and the first detection mechanism 3 is located on the side of the mounting frame 4 closer to the heating device 100.

[0035] Specifically, such as Figures 1 to 6As shown, the transmission mechanism 2 further includes: a first transmission wheel 22, a second transmission wheel 23, a transmission belt 24, and a push rod 25. The first transmission wheel 22 and the second transmission wheel 23 are spaced apart on the mounting frame 4 along the moving direction of the push plate 1, and both the first transmission wheel 22 and the second transmission wheel 23 are rotatably arranged relative to the mounting frame 4. The second transmission wheel 23 is located on the side of the mounting frame 4 near the heating device 100, and the second transmission wheel 23 and the first detection mechanism 3 are spaced apart along the length direction of the heating device 100. The transmission belt 24 The transmission mechanism 2 is mounted on the first transmission wheel 22 and the second transmission wheel 23 to drive the transmission belt 24 to move via the first transmission wheel 22 or the second transmission wheel 23; the contact plate 21 is mounted on the transmission belt 24 to drive the contact plate 21 to move along the moving direction of the push plate 1 via the transmission belt 24; one end of the push rod 25 is connected to the transmission belt 24, and the other end of the push rod 25 is connected to the push plate 1, so that the transmission belt 24 can drive the push plate 1 to move via the push rod 25; the end of the push rod 25 near the push plate 1 forms the output part of the transmission mechanism 2.

[0036] With this structural configuration, the drive belt 24, driven by the first drive pulley 22 and the second drive pulley 23, provides smooth and continuous motion, ensuring that the pusher plate 1 maintains a stable speed and direction throughout the pushing process, avoiding food displacement or damage caused by speed fluctuations or sudden starts / stops. Furthermore, compared to gears or other mechanical transmission methods, the drive belt 24 can better absorb and disperse vibrations, reducing noise and mechanical wear during system operation. Simultaneously, the friction between the drive belt 24 and the drive pulleys is low, significantly reducing wear between components compared to gears or other rigid connections, extending the equipment's service life. Moreover, due to the wear resistance and durability of the drive belt, the system requires less maintenance, reducing long-term maintenance costs. In addition, the drive belt 24 can quickly respond to signals from the first detection mechanism 3, promptly adjusting the movement direction of the pusher plate 1, improving the system's response speed.

[0037] Furthermore, by switching the rotation direction of the first transmission wheel 22 and / or the second transmission wheel 23, the movement direction of the transmission belt 24 can be switched, thereby enabling the push plate 1 to be movably set along the width direction of the heating device 100.

[0038] Specifically, such as Figures 1 to 6 As shown, the transmission mechanism 2 further includes: a movable member 26, which is connected to the transmission belt 24 and is located below the transmission belt 24; a push rod 25 is disposed on the movable member 26 at one end away from the push plate 1; and a contact plate 21 is mounted on the movable member 26, protruding from the movable member 26 and located on one side of the transmission belt 24, so that the transmission belt 24 can drive the push rod 25 and the contact plate 21 to move through the movable member 26.

[0039] Furthermore, the contact plate 21 and the transmission belt 24 are spaced apart, one end of the push rod 25 is located on the side of the moving part 26 near the push plate 1, and the other end of the push rod 25 passes through the side plate of the heating device 100 and is connected to the push plate 1.

[0040] Furthermore, there are two push rods 25, which are spaced apart along the length of the push plate 1.

[0041] Specifically, such as Figure 2 and Figure 6 As shown, the pushing device also includes a second detection mechanism 5, which is mounted on the mounting frame 4 and located on the side of the mounting frame 4 away from the push plate 1. The second detection mechanism 5 is used to detect whether the push plate 1 has moved to the initial position. The second detection mechanism 5 is connected to the transmission mechanism 2 to control the transmission mechanism 2 to stop moving based on the detection result of the second detection mechanism 5. The second detection mechanism 5 has a second trigger part 51, which is positioned towards the moving member 26. When the push plate 1 moves to the initial position, the moving member 26 abuts against the second trigger part 51, and the second detection mechanism 5 controls the transmission mechanism 2 to stop moving. With this structural arrangement, the real-time monitoring by the second detection mechanism 5 ensures that the push plate 1 returns to the initial position accurately, avoiding subsequent operational errors caused by inaccurate positioning. The second detection mechanism 5 provides a feedback mechanism, forming a closed-loop control system, which improves the stability and accuracy of the entire system. At the same time, when the push plate 1 returns to the initial position, the second detection mechanism 5 immediately controls the transmission mechanism 2 to stop moving, avoiding unnecessary energy consumption and saving energy. Timely shutdown can also reduce the excessive use of the transmission belt 24 and other mechanical components, extending the service life of the equipment.

[0042] Furthermore, the second testing mechanism 5 is a second limit switch.

[0043] Furthermore, the second detection mechanism 5 and the first transmission wheel 22 are spaced apart.

[0044] Specifically, such as Figures 1 to 6As shown, the mounting frame 4 includes two guide frames 41, which are spaced apart along the length of the heating device 100. The transmission belt 24 and the moving part 26 are both located between the two guide frames 41. Each guide frame 41 has a guide channel 410, which extends along the moving direction of the push plate 1. The transmission mechanism 2 also includes two guide wheels 27, which are correspondingly arranged with the two guide frames 41. The two guide wheels 27 are rotatably arranged on opposite sides of the moving part 26. Each guide wheel 27 is movably arranged on the corresponding guide channel 410 along the extending direction of the corresponding guide channel 410. With this structural arrangement, the design of the guide wheels 27 and the guide channels 410 ensures that the push plate 1 can move accurately on the predetermined path, reducing errors caused by offset or jamming and improving the pushing accuracy. Furthermore, the guide wheels 27 and the guide channels 410 provide stable physical constraints, preventing the push plate 1 from deviating during movement and ensuring that each push can complete the task accurately. Meanwhile, the movement of the guide wheel 27 within the guide channel 410 provides smooth guidance, reducing friction and vibration, and enabling the push plate 1 to reciprocate smoothly. Furthermore, the design of the guide wheel 27 makes the movement of the push plate 1 smoother, reducing friction and wear between mechanical parts and extending the service life of the equipment.

[0045] Specifically, such as Figure 4 As shown, the guide frame 41 is provided with two limiting grooves 411, which are located at both ends of the guide channel 410 and are connected to the guide channel 410. The two limiting grooves 411 limit the guide wheel 27. When the push plate 1 is in the initial position, the guide wheel 27 is located in the limiting groove 411 further away from the push plate 1. When the push plate 1 is in the delivery position, the guide wheel 27 is located in the limiting groove 411 closer to the push plate 1. With this structure, the limiting grooves 411 provide a clear stopping point for the guide wheel 27, ensuring that the push plate 1 can stop accurately in the initial and delivery positions, reducing operational errors caused by small deviations. The stop of the guide wheel 27 in the limiting groove 411 provides additional mechanical constraint, ensuring that the push plate 1 remains stable throughout the movement, reducing vibration and shaking.

[0046] Specifically, such as Figures 1 to 6 As shown, the pushing device also includes: a driving mechanism 6, which is driven to the input part of the transmission mechanism 2. The driving mechanism 6 drives the transmission mechanism 2 to move, thereby driving the push plate 1 to move. The first detection mechanism 3 is connected to the transmission mechanism 2 through the driving mechanism 6, and controls the action of the driving mechanism 6 based on the detection result of the first detection mechanism 3.

[0047] Furthermore, the drive mechanism 6 is connected to the first transmission wheel 22, and the drive mechanism 6 drives the first transmission wheel 22 to move, thereby driving the transmission belt 24 and the second transmission wheel 23 to move. By switching the rotation direction of the drive mechanism 6, the reciprocating movement of the push plate 1 is achieved. The first transmission wheel 22 forms the input part of the transmission mechanism 2.

[0048] Furthermore, the rotation direction of the first transmission wheel 22 can be switched by switching the rotation direction of the drive mechanism 6.

[0049] Furthermore, the drive mechanism 6 is a geared motor.

[0050] Optionally, the working process of the driving device is as follows:

[0051] 1. Initial state:

[0052] The push plate 1 is in the initial position, the guide wheel 27 is in the limiting groove 411 away from the push plate 1 in the two limiting grooves 411, and the transmission mechanism 2 is in a stationary state.

[0053] 2. Start push notifications:

[0054] Once the heating device 100 has finished heating, the drive mechanism 6 is activated, driving the first transmission wheel 22 to rotate counterclockwise, which in turn drives the transmission belt 24. The transmission belt 24 then moves the push rod 25, causing the push plate 1 to move from its initial position toward the shipping position.

[0055] 3. Push process:

[0056] During the movement of the push plate 1, the guide wheel 27 rolls smoothly along the guide channel 410, ensuring that the push plate 1 moves along the predetermined path and does not deviate from the track.

[0057] 4. Triggering and Control:

[0058] When the push plate 1 reaches the delivery position and pushes the food completely into the delivery compartment, the contact plate 21 abuts against the first trigger part 31, and then the first trigger part 31 of the first detection mechanism 3 sends a trigger signal and sends a command to the drive mechanism 6. The drive mechanism 6 starts to switch the rotation direction, thereby driving the first transmission wheel 22 in the transmission mechanism 2 to rotate clockwise, causing the transmission belt 24 to move in the opposite direction, thereby driving the push plate 1 back to the initial position.

[0059] 5. Reset detection and stop:

[0060] When the push plate 1 returns to the initial position, the guide wheel 27 enters the limiting groove 411 away from the push plate 1 in the two limiting grooves 411, and the moving part 26 abuts against the second trigger part 51 of the second detection mechanism 5. Then the second detection mechanism 5 sends a signal to the drive mechanism 6, and the drive mechanism 6 stops moving, thereby stopping the transmission mechanism 2 so that the push plate 1 is kept in the initial position.

[0061] This utility model also provides a hot food machine, including: a cabinet, a heating device 100, a dispensing compartment, and a pushing device. The heating device 100 is disposed inside the cabinet. The heating device 100 has a heating space 103, and an inlet 101 and a dispensing outlet 102 connected to the heating space 103. The inlet 101 is located at the top of the heating device 100 for unheated food to enter the heating space 103. The dispensing outlet 102 is located on the side wall of the heating device 100. The dispensing compartment is disposed inside the cabinet, and the dispensing compartment and the heating device 100 are spaced apart along the width direction of the heating device 100.
