Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to an anti-jamming dial structure for a fryer. Background Technology

[0002] In the food processing industry, frying is a common and important processing method, widely used in the production of various snack foods such as potato chips, shrimp crackers, and spring rolls, as well as meat and noodle products. As the core equipment for realizing the frying process, the performance of the frying machine directly affects the frying quality, production efficiency, and economic benefits of the enterprise. Frying machines are usually equipped with a rotary wheel structure, the main function of which is to stir the food during the frying process.

[0003] However, the existing fryer dial structure lacks an effective anti-jamming design. In actual production, due to the wide variety of fried foods with different shapes, sizes and textures, some foods are prone to sticking or deforming during frying, which can easily get stuck between the blades of the dial and cause jamming. Therefore, we need to propose an anti-jamming dial structure for fryers. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-jamming dial structure for a fryer. By setting an arc-shaped lever, a torque sensing device, an assist component, and a collaborative structure, it achieves the effect of preventing jamming and ensuring continuous production, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An anti-jamming dial structure for a deep fryer includes: a deep fryer body with an oil tank on its top, a bracket fixedly connected to the top of the deep fryer body, a dial wheel rotatably mounted on the bottom of the bracket, and a dial rod on the dial wheel being arc-shaped. A power assembly for driving the dial to rotate is located on the top of the bracket. The top of the dial passes through the bracket and is connected to the output end of the power assembly through a torque sensing device. An assist component to prevent the dial from jamming due to excessive resistance is located at the top of the bracket.

[0006] Preferably, the power assembly includes an active component, a driven component, and a drive motor. The active component and the driven component mesh with each other. The active component is connected to the drive motor through a rotating rod. The drive motor is fixedly installed on the top of the bracket.

[0007] Preferably, the driven member serves as the output end of the power assembly, and the top of the dial is fixedly connected to the driven member via a torque sensing device.

[0008] Preferably, the assist component includes an electric push rod, which is fixedly installed on the top of the bracket. One end of the telescopic end of the electric push rod is fixedly connected to a toothed plate, and one side of the toothed plate can mesh with the driven member.

[0009] Preferably, it also includes a support block, which is fixedly connected to the top of the bracket. A limiting groove is formed on the top of the support block, and a protrusion adapted to the limiting groove is fixedly connected to the bottom of the toothed plate. The protrusion is slidably connected inside the limiting groove.

[0010] Preferably, the teeth of the driving member, the driven member, and the toothed plate are all wedge-shaped teeth that can mesh in one direction.

[0011] Preferably, a support rod is fixedly connected to the outer wall of the fryer body, and a food drain plate is fixedly connected to the top of the support rod at an incline. An oil outlet groove is opened on one side of the food drain plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: An anti-jamming dial structure for a deep fryer includes: a deep fryer body 1 with an oil tank 2 on its top; a bracket 3 fixedly connected to the top of the deep fryer body 1; a dial 4 rotatably mounted on the bottom of the bracket 3; and a dial rod 13 on the dial 4 with an arc shape. By setting the dial rod 13 in an arc shape, the hard contact and hooking between the dial rod 13 and the food are reduced, thereby reducing the probability of food getting stuck between the dial rods 13.

[0018] It also includes a power assembly 6 for driving the dial 4 to rotate, which is set on the top of the bracket 3. The top of the dial 4 passes through the bracket 3 and is connected to the output end of the power assembly 6 through a torque sensing device 7. The torque sensing device 7 is set as a torque sensor. By setting the torque sensing device 7, the resistance change of the dial 4 during operation can be monitored in real time, and the effect of timely detection of jamming risk can be achieved.

[0019] It is worth noting that the torque sensing device 7 (torque sensor) can use an FCA7300 steering wheel torque sensor. This sensor has the function of measuring steering torque, steering angle and steering speed. It can test in both forward and reverse directions and can adapt to a variety of complex scenarios. It has overload protection capability exceeding 10 times the rated range of the sensor, with a range of 10 to 250 Nm, an operating temperature range of -20℃ to 80℃, and an accuracy of ±0.1%. By setting the FCA7300 steering wheel torque sensor as the torque sensing device 7, the effect of real-time and accurate monitoring of torque changes when the dial wheel 4 is running is achieved. When the resistance of the food to the dial wheel 4 increases and the torque value exceeds the preset threshold, the torque signal can be converted into an electrical signal and transmitted to the control system in a timely manner to trigger the power steering component 5 to work, effectively preventing the dial wheel 4 from jamming.

[0020] It also includes an assist component 5 located on the top of the bracket 3 to prevent the dial 4 from jamming due to excessive resistance. By setting the assist component 5, additional driving force can be provided when the dial 4 has excessive resistance, thus achieving the effect of preventing the dial 4 from jamming.

[0021] In this embodiment, the power assembly 6 includes a driving member 601, a driven member 602, and a drive motor 603. The driving member 601 and the driven member 602 mesh with each other. The driving member 601 is connected to the drive motor 603 via a rotating rod. The drive motor 603 is fixedly mounted on the top of the bracket 3. By setting the meshing driving member 601 and the driven member 602, and cooperating with the drive motor 603 to provide power, the effect of stably driving the dial wheel 4 to rotate is achieved.

[0022] Furthermore, for the drive motor 603, the TMC603A-LA three-phase BLDC motor pre-drive chip can be selected to match the appropriate motor. The TMC603A-LA is a three-phase BLDC gate driver suitable for high-load scenarios such as industrial automation. It can drive a gate current of up to 150mA, has a working power supply voltage range of 12 to 50V, and provides a PWM interface for easy connection with the control system. By setting the motor driven by the TMC603A-LA as the drive motor 603, a stable and efficient power output is achieved for the power component 6, ensuring that the dial 4 can rotate continuously and stably to effectively stir the food in the oil tank 2.

[0023] Furthermore, the driven member 602 serves as the output end of the power assembly 6, and the top of the dial 4 is fixedly connected to the driven member 602 via the torque sensing device 7. By setting the driven member 602 as the output end and connecting it to the torque sensing device 7, the combination of power transmission and real-time acquisition of torque signals is achieved, thus realizing the effect of accurately monitoring and feeding back the operating resistance of the dial 4.

[0024] Specifically, the assist component 5 includes an electric push rod 501, which is fixedly mounted on the top of the bracket 3. One end of the telescopic end of the electric push rod 501 is fixedly connected to a toothed plate 502, and one side of the toothed plate 502 can mesh with the driven member 602. By setting the electric push rod 501 to drive the toothed plate 502 to mesh with the driven member 602, additional driving force can be provided to the driven member 602 when needed, thereby enhancing the driving force of the dial wheel 4.

[0025] Furthermore, for the electric linear actuator 501, the XYDHA36-100 model can be selected. This electric linear actuator is controlled by a PC and can meet the precise control requirements of the power assist component 5. It has a certain thrust and stroke range, which can drive the toothed plate 502 to mesh smoothly with the driven member 602. By setting the XYDHA36-100 model electric linear actuator 501, the effect of providing stable and controllable driving force for the power assist component 5 is achieved, ensuring that when the dial wheel 4 is at risk of jamming, additional power can be provided in time to overcome the jamming resistance.

[0026] Furthermore, it also includes a support block 503, which is fixedly connected to the top of the bracket 3. A limiting groove 504 is formed on the top of the support block 503, and a protrusion 505 adapted to the limiting groove 504 is fixedly connected to the bottom of the toothed plate 502. The protrusion 505 is slidably connected inside the limiting groove 504. By setting the cooperation of the limiting groove 504 and the protrusion 505, the movement of the toothed plate 502 is guided and limited, achieving the effect of ensuring precise meshing between the toothed plate 502 and the driven member 602.

[0027] It should be noted that the teeth of the driving component 601, the driven component 602, and the toothed plate 502 are all wedge-shaped teeth 8 that can mesh in one direction. By setting the wedge-shaped teeth 8 that mesh in one direction, it is ensured that the power can only be transmitted in one direction, avoiding the interference of the reverse force on the components, and achieving the effect of ensuring the stability of power transmission.

[0028] In this embodiment, a support rod 9 is fixedly connected to the outer wall of the fryer body 1. A food drain plate 10 is fixedly connected to the top of the support rod 9 at an incline. An oil outlet groove 11 is provided on one side of the food drain plate 10. By setting the inclined food drain plate 10 and the oil outlet groove 11, it is convenient to drain excess oil from the fried food and recycle it, thus achieving the effects of saving oil and ensuring the taste of the food.

[0029] As an alternative, mounting grooves 12 are provided on both side walls of the bracket 3, and the food drain plate 10 is installed at an angle inside the mounting grooves 12 by means of clips. By setting the mounting grooves 12 and clips, the food drain plate 10 can be easily installed and removed, achieving the effect of facilitating cleaning and maintenance of the food drain plate 10.

[0030] Working principle: After the drive motor 603 starts, it drives the active component 601 to rotate via the rotating rod. The active component 601 meshes with the driven component 602, thereby driving the driven component 602 to rotate. The driven component 602 drives the dial wheel 4 to rotate in the oil tank 2 through the torque sensing device 7 (torque sensor). The arc-shaped lever 13 stirs the food in the oil tank 2. The working principle of the torque sensor is as follows: its two ends are connected to the top of the driven component 602 and the dial wheel 4, respectively. When the dial wheel 4 rotates, the torque sensor will detect the torque value transmitted from the driven component 602 to the dial wheel 4 in real time and convert the torque signal into an electrical signal and transmit it to the control system. When the dial wheel 4 shows a tendency to jam, the resistance of the food to the dial wheel 4 increases, causing the transmitted torque value to exceed the preset threshold. At this time, the electrical signal transmitted by the torque sensor triggers the control system to start the assist component 5. The electric push rod 501 pushes the toothed plate 502 to move. Under the guiding and limiting action of the protrusion 505 and the limiting groove 504, the toothed plate 502 precisely meshes with the driven member 602, providing additional driving force to the driven member 602 and overcoming jamming resistance. The unidirectional wedge-shaped teeth 8 ensure that power can only be transmitted from the driving member 601 and the toothed plate 502 to the driven member 602, avoiding the interference of reverse force on the drive motor 603 and the electric push rod 501. The fried food is removed and placed on the food drain plate 10. Excess oil flows back to the oil tank 2 along the inclined plate surface through the oil outlet groove 11. The food drain plate 10 is installed in the mounting groove 12 by a snap fastener, which facilitates regular disassembly and cleaning.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
