Description

A pot body tilting structure and an automatic discharging device based thereon Technical Field

[0001] This invention relates to the field of agricultural product processing equipment, and in particular to a pot body tilting structure and an automatic discharging device based thereon. Background Technology

[0002] A tea-frying machine is a specialized piece of machinery used in the withering and frying stages of tea processing, designed to replace traditional hand-frying. The machine uses a swishing plate to stir the tea leaves in the wok. The tea leaves are squeezed, rubbed, and their moisture content reduced through heat shrinkage, thus shaping the tea. The transmission mechanism of the swishing plate uses two sets of crank-connecting rods with different structural parameters. Power is manually transmitted through different crank-connecting rod sets, allowing for switching between different swishing amplitudes. The frequency of the swishing plate's movement can be changed via a frequency converter. The entire transmission structure is simple, and the wok is heated using traditional electric heating elements.

[0003] Existing tea-frying machines rely on manual feeding and unloading due to machine limitations. Especially in continuous and large-scale production scenarios, dedicated personnel are required to be responsible for the timing and operation of the unloading of each machine. Due to the different timing of unloading, the quality of the tea produced varies, and labor costs are significantly increased. When manually turning or tilting, there is a risk of burns due to contact with the high-temperature pot, or the pot may tip over due to instability caused by hurried operation, creating safety hazards. When unloading manually, the tea leaves are easily subjected to violent shaking, impact, or compression during the unloading process, resulting in more broken leaves and buds, which damages the tea leaves and affects the quality of the output. Summary of the Invention

[0004] This application provides a pot body tilting structure and an automatic discharging device based thereon, adopting the following technical solution: a pot body tilting structure, including a machine body and a pot body assembly, wherein the pot body assembly is rotatably connected to the machine body; further comprising: a pot body tilting component, wherein the pot body tilting component is disposed on the machine body and connected to the pot body assembly, and the pot body tilting component drives the pot body assembly to tilt around its rotation center.

[0005] Preferably, the pot body assembly is fixedly connected to two sides of a rotating shaft, and the machine body is provided with a bearing seat that matches the rotating shaft. The pot body assembly is rotatably connected to the machine body through the rotating shaft and the bearing seat.

[0006] Preferably, the pot body tilting assembly includes an arc-shaped toothed ring, which is fixedly connected to the bottom of the pot body assembly. A servo motor is installed on the machine body, and a transmission tooth is fixedly connected to one end of the servo motor. The transmission tooth meshes with the arc-shaped toothed ring.

[0007] Preferably, the arc center of the arc-shaped gear ring coincides with the rotation center of the pot body assembly, and the arc-shaped gear ring meshes with the servo motor through the transmission teeth to drive the pot body assembly to rotate.

[0008] An automatic discharging device based on a pot body tilting structure includes the aforementioned machine body, pot body assembly, and pot body tilting assembly, and further includes: a controller, the controller being mounted on the machine body; and a sensor group, the sensor group being signal-connected to the controller, the sensor group detecting the position state of the pot body assembly after tilting and resetting, and sending feedback signals to the controller, the controller controlling the pot body tilting assembly to perform tilting or resetting actions according to the signals fed back by the sensor group.

[0009] Preferably, the sensor group is divided into a position sensor and an opening limit sensor. The position sensor detects the position state of the pot body assembly after it is reset, and the opening limit sensor detects the position state of the pot body assembly after it is flipped.

[0010] Preferably, the positioning sensor is disposed on the machine body, the positioning sensor is located between the pot body tilting assembly and the pot body assembly, and the opening limit sensor is located below the positioning sensor.

[0011] Preferably, it further includes: a buffer block, the buffer block being installed on the machine body, and a buffer plate being provided at the rear end of the pot body assembly, the buffer plate abutting against the buffer block.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The pot body flipping structure uses an arc-shaped gear ring fixed to the bottom of the pot body assembly. The arc-shaped gear ring meshes with the transmission gear driven by the servo motor, thereby driving the pot body assembly to flip. The arc center of the arc-shaped gear ring coincides with the rotation center of the pot body, ensuring that the arc-shaped gear ring always maintains good meshing with the transmission gear during the flipping process of the pot body assembly. The transmission is more stable, and the pot body flips more smoothly, resulting in more stable material discharge and effectively improving the quality of the output. There will be no tooth slippage or misalignment. Moreover, compared with belts, connecting rods, and other methods, gear meshing transmission has higher transmission efficiency and load capacity, which is suitable for pot bodies such as tea frying machines that may have a certain weight and inertia.

[0013] 2. This automatic discharging device, through a pre-set program by the controller, automatically flips the pot body component to discharge the material after processing, eliminating the need for manual intervention. The controller can automatically execute the process, effectively reducing labor costs and improving production efficiency. It is suitable for continuous and large-scale production. Furthermore, it effectively avoids the risk of burns and other safety hazards caused by manual operation of the pot body component in high-temperature, high-humidity, or busy production environments. The discharging process is smoothly driven by a servo motor, avoiding external impacts or rapid manual tilting. The entire process is controllable and low-impact, preventing broken leaves and buds from being violently shaken or impacted during discharging, effectively maintaining the integrity and quality of the tea leaves at the time of discharge.

[0014] 3. This automatic discharging device monitors the position of the pot assembly in real time during the flipping and reset states using position sensors and limit sensors. When the pot assembly reaches the sensor position, the sensor transmits a signal to the controller, which then controls the servo motor to stop. The servo motor and the pot assembly are driven by a transmission gear meshing with an arc-shaped gear ring. During the motor's stop, the servo motor's own braking control and the physical coupling of the gear transmission effectively suppress the pot assembly's continued rotation due to its own inertia, improving positioning accuracy and allowing it to decelerate and stop smoothly. Buffer blocks and buffer plates are also provided to effectively reduce impact and protect the machine body and transmission structure. Attached Figure Description

[0021] Embodiments of the present invention provide a pot body tilting structure and an automatic discharging device based thereon.

[0022] Example: As shown in Figures 4-5: A pot-body flipping structure includes a machine body 1 and a pot body assembly 2, the pot body assembly 2 being rotatably connected to the machine body 1; it also includes a pot-body flipping component 3. This pot-body flipping structure is mainly used in tea-frying machines. By controlling the pot-body flipping component 3, the precise flipping of the pot body assembly 2 is achieved to complete the tea discharge. This structure balances stability and flexibility and can adapt to pots of different sizes and styles. The pot-body flipping component 3 is disposed on the machine body 1 and connected to the pot body assembly 2. The pot-body flipping component 3 drives the pot body assembly 2 to flip around its rotation center.

[0023] The pot body assembly 2 is fixedly connected to two sides by rotating shafts 201. The rotating shafts 201 are preferably made of high-strength alloy material and have a hardened surface to reduce wear. The axis of the rotating shafts 201 is the rotation center of the pot body assembly 2. The machine body 1 is provided with a bearing seat 202 that matches the rotating shafts 201. The pot body assembly 2 is rotatably connected to the machine body 1 via the rotating shafts 201 and the bearing seat 202. Optionally, a limiting structure, such as a stop pin or a groove, can be added between the rotating shafts 201 and the bearing seat 202 to prevent axial movement of the pot body assembly 2.

[0024] The pot body tilting assembly 3 includes an arc-shaped gear ring 301, which is fixedly connected to the bottom of the pot body assembly 2. The fixing method can be welding, bolting, or integral die casting; no specific limitation is made to this method. Optional reinforcing ribs can be added to the back of the arc-shaped gear ring 301 to improve rigidity. A servo motor 302 is mounted on the body 1, and a transmission gear 303 is fixedly connected to one end of the servo motor 302. The transmission gear 303 meshes with the arc-shaped gear ring 301. This meshing transmission structure enables precise angle control. The servo motor 302 supports start / stop and emergency stop responses and can achieve segmented speed-changing tilting through a preset program, preventing tea splashing or mechanical damage to the pot body assembly 2 due to inertial impact.

[0025] The arc length of the arc-shaped gear ring 301 covers the maximum rotation angle range required by the pot assembly 2. The center of the arc of the arc-shaped gear ring 301 coincides with the rotation center of the pot assembly 2. The pitch circle radius of the arc-shaped gear ring 301 is consistent with the distance to the axis of the rotating shaft 201 to ensure that the gear meshing pressure angle is constant during transmission and reduce off-center wear. The arc-shaped gear ring 301 meshes with the servo motor 302 through the transmission teeth 303 to drive the pot assembly 2 to rotate.

[0026] As shown in Figure 1, an automatic discharging device based on a pot-body tilting structure includes a machine body 1 and a pot body assembly 2, which is rotatably connected to the machine body 1. It also includes a pot-body tilting assembly 3. This pot-body tilting structure is mainly used in tea-frying machines. By controlling the pot-body tilting assembly 3, the precise tilting of the pot body assembly 2 is achieved to complete the discharging of tea leaves. This structure balances stability and flexibility, and can adapt to pots of different sizes and styles. The pot-body tilting assembly 3 is mounted on the machine body 1 and connected to the pot body assembly 2. The pot-body tilting assembly 3 drives the pot body assembly 2 to tilt around its rotation center.

[0027] The pot body assembly 2 is fixedly connected to two sides by rotating shafts 201. The rotating shafts 201 are preferably made of high-strength alloy material and have a hardened surface to reduce wear. The axis of the rotating shafts 201 is the rotation center of the pot body assembly 2. The machine body 1 is provided with a bearing seat 202 that matches the rotating shafts 201. The pot body assembly 2 is rotatably connected to the machine body 1 via the rotating shafts 201 and the bearing seat 202. Optionally, a limiting structure, such as a stop pin or a groove, can be added between the rotating shafts 201 and the bearing seat 202 to prevent axial movement of the pot body assembly 2.

[0028] The pot body tilting assembly 3 includes an arc-shaped gear ring 301, which is fixedly connected to the bottom of the pot body assembly 2. The fixing method can be welding, bolting, or integral die casting; no specific limitation is made to this method. Optional reinforcing ribs can be added to the back of the arc-shaped gear ring 301 to improve rigidity. A servo motor 302 is mounted on the body 1, and a transmission gear 303 is fixedly connected to one end of the servo motor 302. The transmission gear 303 meshes with the arc-shaped gear ring 301. This meshing transmission structure enables precise angle control. The servo motor 302 supports start / stop and emergency stop responses and can achieve segmented speed-changing tilting through a preset program, preventing tea splashing or mechanical damage to the pot body assembly 2 due to inertial impact.

[0029] The arc length of the arc-shaped gear ring 301 covers the maximum rotation angle range required by the pot assembly 2. The center of the arc of the arc-shaped gear ring 301 coincides with the rotation center of the pot assembly 2. The pitch circle radius of the arc-shaped gear ring 301 is consistent with the distance to the axis of the rotating shaft 201 to ensure that the gear meshing pressure angle is constant during transmission and reduce off-center wear. The arc-shaped gear ring 301 meshes with the servo motor 302 through the transmission teeth 303 to drive the pot assembly 2 to rotate.

[0030] As shown in Figure 6, the system also includes a controller 6, which is mounted on the main body 1. The controller 6 is preferably an integrated control module with a built-in logic processing unit and storage unit. It receives real-time feedback signals from the sensor group and generates control commands based on a preset program to drive the servo motor 302 in the pot body tilting assembly 3 to precisely execute tilting or reset actions. Through the collaborative work of the sensor group and the controller 6, the system can support multiple intelligent modes: for example, automatically detecting whether the pot body assembly 2 is in the reset state (initial position) before the cooking program starts; if not reset, triggering the reset action first; triggering a fault protection mechanism (such as pausing operation or alarm prompting) when an abnormality is detected (such as sensor signal loss or pot body not reaching its position within timeout). This design achieves automated closed-loop control of the pot body assembly 2 tilting process, ensuring the reliability of the action and the accuracy of the position.

[0031] As shown in Figures 2-3 and 8, the system also includes a sensor group connected to the controller 6. The sensor group detects the position of the pot assembly 2 after flipping and resetting, and sends a feedback signal to the controller 6. The controller 6 controls the pot flipping assembly 3 to perform a flipping or resetting action based on the feedback signal from the sensor group. The sensor group consists of a position sensor 4 and an opening limit sensor 5. The position sensor 4 and opening limit sensor 5 can be metal sensors, photoelectric sensors, Hall effect sensors, etc., to ensure that when the pot assembly 2 approaches or is touched, the sensor group can identify information and send a signal to the controller 6. The specific sensor selection is not specifically limited. The position sensor 4 detects the position of the pot assembly 2 after resetting, and the opening limit sensor 5 detects the position of the pot assembly 2 after flipping. The position sensor 4 is disposed on the machine body 1, located between the pot flipping assembly 3 and the pot assembly 2, and the opening limit sensor 5 is located below the position sensor 4.

[0032] As shown in Figure 7, the system also includes a buffer block 7. The buffer block 7 is an elastic buffer component, and its material can be polyurethane, rubber, composite damping, etc. No specific material is limited. Its main function is to reduce the impact force through the contact between the buffer plate 203 and the buffer block 7 when the pot assembly 2 returns to its initial position, preventing structural damage to the machine body 1, pot assembly 2, and other components caused by rigid collisions, and effectively reducing noise generation after resetting. The buffer block 7 is installed on the machine body 1, and the buffer plate 203 is provided at the rear end of the pot assembly 2, with the buffer plate 203 abutting against the buffer block 7.

[0033] In use, this invention works as follows: After the frying process is completed, the controller 6 sends a command to start the servo motor 302. The servo motor 302 rotates, driving the transmission gear 303 to rotate. The transmission gear 303 meshes with the arc-shaped gear ring 301, causing the arc-shaped gear ring 301 to tilt. The pot assembly 2 then rotates around the axis of the rotating shaft 201 until it tilts and flips. During this tilting process, when the pot assembly 2 approaches and is detected by the limit sensor 5, the limit sensor 5 transmits a signal to the controller 6. Upon receiving the signal, the controller 6 sends a command to stop the servo motor 302. The stopping time of the tilted pot assembly 2 is adjusted by the controller 6's control program. After the fried tea leaves are poured out of the pot assembly 2, the controller 6 sends another signal to start the servo motor 302. This time, the servo motor 302 rotates in the opposite direction, causing the pot assembly 2 to rotate around the axis of the rotating shaft 201 and reset. During the rotation and reset process, when the position sensor 4 detects that the pot assembly 2 is close, the position sensor 4 sends a signal to the controller 6. The controller 6 controls the servo motor 302 to stop rotating. At this time, the buffer plate 203 on the pot assembly 2 contacts the buffer block 7 on the machine body 1, reducing the damage caused by the inertia of the pot assembly 2 to the machine body 1 and other components.
