Technical Field
[0001] This utility model relates to the technical field of tea processing equipment, and in particular to a fully automatic tea stir-frying device that stirs and stirs the leaves evenly. Background Technology
[0002] The traditional steps of pan-frying green tea are as follows: First, spread the fresh leaves thinly to dry and remove surface water. Heat the wok until it just starts to smoke. When you can feel the heat when you hold your hand about a foot away from the center of the wok, add the leaves. Quickly stir-fry and shake the leaves to ensure they are heated evenly. As the green smell gradually fades, switch to a combination of shaking and steaming. Once the leaves are soft and sticky, knead them into strips while they are still hot. Continue stirring and kneading until the strips are tightly rolled. Then, raise the temperature to "finally finish" the wok to shape and enhance the aroma. Once the leaves can be crushed into powder and have a fragrant aroma, remove them from the wok and let them cool. Chinese Patent Publication No. CN210901221U discloses a pan-frying device for oolong tea production, which solves the shortcomings of the prior art. The device includes a pan-frying box, a rotating shaft, and a cylinder. The top of the pan-frying box is provided with a feeding port, and the pan-frying box is provided with a stirring chamber and an installation chamber. The installation chamber is located below the stirring chamber. The rotating shaft is rotatably connected to the stirring chamber and is provided with multiple stirring racks. The cylinder is located at the bottom of the installation chamber, and the top of the piston rod in the cylinder is provided with a bottom cover. The bottom cover matches the through hole opened at the bottom of the inner wall of the stirring chamber. The bottom of the stirring chamber is provided with a heating plate, and a temperature sensor is provided on one side of the heating plate. The installation chamber is provided with an inclined sliding plate, and the lower end of the sliding plate is provided with a discharge port. The stirring racks stir the tea leaves up and down, so that the tea leaves at the bottom are constantly turned up, making the tea leaves stir-fried more evenly. The above-mentioned technology relies solely on the up-and-down stirring of the tea leaves, which always accumulates at the bottom and cannot be evenly spread and heated, resulting in a limited heating area and poor heating uniformity, which restricts the improvement of tea quality. To address this problem, this utility model discloses a fully automatic tea stir-frying device that can stir and fry evenly. Utility Model Content
[0003] The purpose of this utility model is to provide a fully automatic tea frying device that can stir and stir evenly, in order to solve the technical problem in the above-mentioned background technology that traditional tea frying devices rely solely on the up-and-down stirring of the frying rack, resulting in the tea leaves always piling up at the bottom and failing to be evenly spread and heated, thus limiting the heating area and the uniformity of heating, which restricts the improvement of tea quality.
[0004] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A fully automatic tea-frying device for even stirring includes a lower cabinet, an upper cabinet above the lower cabinet, a connecting plate fixedly connected between the lower and upper cabinets, a first motor fixedly installed inside the upper cabinet, a frying pan connected to the upper side of the lower cabinet via a vibration component, a spreading component inside the frying pan, and a lifting component installed on the connecting plate between the lower and upper cabinets. The output end of the first motor is connected to the spreading component via the lifting component. The wok has a material trough that gradually decreases in height from the edge to the center on its upper side. The lowest end of the material trough has a discharge port. The material spreading component includes a filling column whose bottom end is embedded in the discharge port. The top end of the filling column is connected to a lifting component. The portion of the filling column inside the wok is fixed with a connecting ring. Multiple blades are evenly spaced on the outer circumference of the connecting ring.
[0005] As a further embodiment of this utility model, a retaining ring is fixed at the edge of the material trough, and multiple electric heating plates are fixedly installed on the bottom wall of the wok.
[0006] As a further embodiment of this utility model, the lifting assembly includes a hinge seat fixed to the connecting plate, a spline sleeve fixed to the output end of the first motor, and a lifting sleeve sleeved on the outer side of the bottom end of the spline sleeve. A spline shaft is rotatably embedded on the bottom end surface of the lifting sleeve. The top end of the spline shaft extends into the spline sleeve, and the bottom end of the spline shaft is fixed to the filling column. A linkage plate is hinged to the hinge seat. A handrail is fixedly connected to the end of the linkage plate. A sliding groove is provided on the linkage plate, and a cylinder is provided in the sliding groove. The cylinder is fixed to the lifting sleeve.
[0007] As a further embodiment of this utility model, the upper side of the lower cabinet is provided with a receiving groove, a notch is opened on one side of the receiving groove, and a guide frame that is inclined is fixedly connected between the bottom wall of the notch and the inner wall of the other side of the receiving groove. The guide frame is positioned directly opposite the discharge port.
[0008] As a further embodiment of this utility model, the vibration assembly includes a mounting ring fixed to the inner wall of the trough, a plurality of vertical rods are slidably embedded on the mounting ring, the top ends of the vertical rods are fixedly connected to the bottom wall of the wok, and a spring is sleeved on the outer side of the vertical rods and located between the mounting ring and the wok.
[0009] As a further embodiment of this utility model, the vibration assembly also includes a vibration box fixed to the upper side of the retaining ring, a second motor fixed inside the vibration box, and a cam fixed to the output end of the second motor.
[0010] As a further embodiment of this utility model, casters are fixed at the four corners of the bottom of the lower cabinet, and wheel brakes are installed on each caster.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a fully automatic tea frying device that ensures even stirring. A second motor drives a cam to rotate at high speed, generating periodic excitation force which is transmitted to the entire frying pan through a vibration box and a retaining ring. A first motor continuously outputs torque, which drives the filling column to rotate through a spline sleeve and a spline shaft. The connecting ring and multiple blades fixed on the filling column rotate at a uniform speed or intermittently inside the frying pan. The rotating blades generate radial centrifugal force while repeatedly stirring the tea leaves. This centrifugal force can push the tea leaves from the center to the surrounding areas. At the same time, under the action of vibration, the tea leaves continuously flow towards the center and turn over. The combined effect of these two actions can achieve dynamic flattening, ensuring that the tea leaves are evenly spread and heated. Even stirring can be completed with a single feeding, significantly improving production capacity and quality consistency. This utility model discloses a fully automatic tea-frying device that ensures even stirring. After frying, the operator holds the handle and lifts the linkage plate. The linkage plate rotates around the hinge seat, and through the linkage between the slide groove and the cylinder, the lifting sleeve slides upward along the spline sleeve. The spline shaft, the filling column, and the entire spreading assembly are lifted simultaneously. The lower end of the filling column disengages from the discharge port, the channel opens, and under the continued vibration, the tea leaves quickly slide into the discharge port along the guide frame and are finally discharged from the guide frame. No manual material removal is required, reducing the risk of burns. Attached Figure Description

[0014] The present invention will be further described below with reference to the embodiments.
[0015] Please see Figure 1-4 This utility model provides a fully automatic tea stir-frying device for even stirring, including a lower cabinet 1, wherein universal wheels 13 are fixed at the four corners of the bottom of the lower cabinet 1, and wheel brakes are installed on the universal wheels 13. Specifically, the operator can easily push the entire machine to the designated work position, and after activating the wheel brake, the universal wheel 13 is locked in place by mechanical buckles or friction plates, which can eliminate the risk of accidental displacement of the equipment.
[0016] Furthermore, an upper cabinet 11 is provided above the lower cabinet 1, and a connecting plate 12 is fixedly connected between the lower cabinet 1 and the upper cabinet 11. A first motor 2 is fixedly installed inside the upper cabinet 11. Specifically, the upper cabinet 11 is provided with heat dissipation holes to facilitate heat dissipation of the first motor 2, and two triangular plates are fixedly connected between the upper cabinet 11 and the connecting plate 12 to enhance the firmness of the connection between the upper cabinet 11 and the connecting plate 12.
[0017] Furthermore, the upper side of the lower cabinet 1 is connected to the wok 4 via a vibration assembly 3. The vibration assembly 3 includes an installation ring 31 fixed to the inner wall of the material trough 41. Multiple vertical rods 32 are slidably embedded on the installation ring 31. The top ends of the vertical rods 32 are all fixedly connected to the bottom wall of the wok 4. A spring 33 is sleeved on the outer side of the vertical rods 32 and between the installation ring 31 and the wok 4. Specifically, when the excitation force transmitted by the vibration box 34 acts on the wok 4, the vertical rod 32 slides vertically along the guide hole of the mounting ring 31, and the spring 33 is compressed or rebounded synchronously. Through elastic deformation, the impact is absorbed and the wok 4 is controlled to vibrate at high frequency and small amplitude only in the vertical direction. This ensures that the vibration energy is efficiently transmitted to the tea leaves and avoids the risk of the wok 4 swaying or colliding due to unrestrained vibration, thus ensuring vibration stability and reliability.
[0018] Furthermore, the vibration assembly 3 also includes a vibration box 34 fixed on the upper side of the retaining ring 43, a second motor 35 fixed inside the vibration box 34, and a cam 36 fixed at the output end of the second motor 35; Specifically, the second motor 35 drives the cam 36 to rotate at high speed. The eccentric structure of the cam 36 generates periodic excitation force during rotation and transmits it to the entire wok 4 through the vibration box 34 and the retaining ring 43. It is worth noting that the vibration box 34 is provided with heat dissipation holes to facilitate heat dissipation of the second motor 35.
[0019] Furthermore, a spreading component 5 is provided inside the wok 4. A material trough 41 with a gradually decreasing height from the edge to the center is provided on the upper side of the wok 4. A discharge port 42 is provided at the lowest end of the material trough 41. The spreading component 5 includes a filling column 51 with its bottom end embedded in the discharge port 42. The top end of the filling column 51 is connected to the lifting component 6. A connecting ring 52 is fixed to the part of the filling column 51 located inside the wok 4. Multiple blades 53 are equidistantly arranged on the outer circumferential surface of the connecting ring 52. Specifically, the inclined bottom surface of the feed trough 41 has an inclination angle of 15°-20°. Under the high-frequency micro-amplitude vibration of the vibration component 3, a directional inertial force is generated, which forces the tea leaves to continuously slide and gather towards the central low-lying area. At the same time, the rotating blades 53 generate radial centrifugal force, which throws the central tea leaves outward to form a circulation process, so that the tea leaves can be turned over in the feed trough 41. This ensures that each tea leaf is evenly in contact with the high-temperature pot bottom, and the tea leaves are dynamically spread out in the feed trough 41. After the tea leaves are fried, the filling column 51 is raised to open the discharge port 42. The tea leaves piled up in the center are accelerated into the discharge port 42 along the inclined feed trough 41 under the vibration. More than 95% of the tea leaves are self-cleaned within 10 seconds, eliminating the risk of residue from manual material removal.
[0020] Furthermore, a retaining ring 43 is fixed at the edge of the material trough 41, and multiple electric heating plates 44 are fixedly installed on the bottom wall of the wok 4. Specifically, the width of the retaining ring 43 is 50-80mm, which can prevent the tea leaves from splashing due to centrifugal force; Specifically, multiple heating plates 44 are embedded in the bottom wall of the wok 4 in a matrix layout, covering more than 80% of the projected area of the material trough 41. This can eliminate uneven temperature caused by single-point heating. It is worth noting that the heating plates 44 generate heat by energizing the built-in heating wires. The heating plates 44 are also equipped with temperature sensors, which are used to detect the real-time temperature of the heating plates 44 and transmit it to the PLC controller. The PLC controller controls the energizing state of the heating wires in the heating plates 44 according to the preset temperature. When the temperature exceeds the limit, the power is cut off, and when the temperature is lower than the preset temperature, the power is restored, thereby achieving precise heating temperature control.
[0021] Furthermore, a lifting assembly 6 is installed on the connecting plate 12 and located between the lower cabinet 1 and the upper cabinet 11. The output end of the first motor 2 is connected to the spreading assembly 5 through the lifting assembly 6. The lifting assembly 6 includes a hinge seat 61 fixed on the connecting plate 12, a spline sleeve 62 fixed on the output end of the first motor 2, and a lifting sleeve 63 sleeved on the outside of the bottom end of the spline sleeve 62. A spline shaft 64 is rotatably embedded on the bottom end surface of the lifting sleeve 63. The top end of the spline shaft 64 extends into the spline sleeve 62. The bottom end of the spline shaft 64 is fixed to the filling column 51. A linkage plate 65 is hinged to the hinge seat 61. A handrail 66 is fixedly connected to the end of the linkage plate 65. A groove 67 is opened on the linkage plate 65. A cylinder 68 is provided in the groove 67. The cylinder 68 is fixed to the lifting sleeve 63. Specifically, the spline sleeve 62 at the output end of the first motor 2 transmits rotational torque to the spline shaft 64 nested therein, causing the filling column 51 and blade 53 fixed at the bottom end of the spline shaft 64 to rotate continuously. The lifting sleeve 63 is sleeved on the outside of the spline sleeve 62, and its fixed cylinder 68 is embedded in the slide groove 67 of the linkage plate 65. When the operator presses down or raises the handrail 66, the linkage plate 65 rotates around the hinge seat 61, and the slide groove 67 forces the cylinder 68 to drive the lifting sleeve 63 to slide along the axial direction of the spline sleeve 62. At this time, the spline shaft 64 moves up and down synchronously in the spline sleeve 62, thereby driving the filling column 51 to disengage from or close the discharge port 42, realizing the rapid switching between sealing the material during roasting and opening the channel during discharge, and the lifting process does not require interrupting the rotation of the blade 53.
[0022] Furthermore, the upper side of the lower cabinet 1 is provided with a receiving groove 111, and a notch 112 is opened on one side of the receiving groove 111. A guide frame 113 arranged in an inclined shape is fixedly connected between the bottom wall of the notch 112 and the inner wall of the other side of the receiving groove 111. The guide frame 113 is arranged directly opposite the discharge port 42. Specifically, when the spreading component 5 is raised to open the discharge port 42, the vibrating wok 4 continuously pushes the tea leaves into the discharge port 42. The tea leaves fall into the guide frame 113 directly opposite by gravity, and are finally discharged into the external receiving container through the notch 112, avoiding manual material handling at high temperatures.
[0023] Working principle: In use, the second motor 35 drives the cam 36 to rotate at high speed, generating periodic excitation force, which is transmitted to the entire wok 4 through the vibration box 34 and the retaining ring 43. This causes the wok 4 to generate high-frequency micro-amplitude vibration under the elastic constraint formed by the vertical rod 32 and the spring 33. At the same time, the first motor 2 continuously outputs torque, which drives the filling column 51 to rotate through the spline sleeve 62 and the spline shaft 64. The connecting ring 52 and multiple blades 53 fixed on the filling column 51 rotate at a uniform speed or intermittently within the wok 4. It is worth noting that in the intermittent mode, the first motor 2 rotates at high speed for one revolution and then pauses, with an interval of 2-3 seconds. This allows the tea leaves that are centrifugally thrown out by the blades 53 to fall back under the action of gravity and then be centrifugally thrown out again. In the uniform rotation mode, the first motor 2 rotates at a low speed, allowing the tea leaves that are centrifugally thrown out by the blades 53 to fall back within the gap between the continuously rotating adjacent blades 53 and then be centrifugally thrown out again. This is suitable for brittle tea leaves to prevent them from being damaged during rapid stir-frying. Both modes ensure the uniformity of stir-frying. After the tea leaves are poured into the trough 41 manually or in the previous process, the rotating blades 53 generate radial centrifugal force and repeatedly stir-fry the tea leaves. With the help of this centrifugal force, the tea leaves can be pushed from the center to the surrounding areas. At the same time, under the action of vibration, the tea leaves continuously flow and turn towards the center. The two can work together to achieve dynamic flattening, ensuring that the tea leaves are evenly spread and heated evenly. The electric heating plate 44 provides a constant stir-frying temperature, and the baffle ring 43 prevents the tea leaves from overflowing. After the tea leaves are stir-fried, the operator holds the handle 66 and lifts the linkage plate 65. The linkage plate 65 rotates around the hinge seat 61. Through the linkage between the slide groove 67 and the cylinder 68, the lifting sleeve 63 slides upward along the spline sleeve 62. The spline shaft 64, the filling column 51 and the entire spreading assembly 5 are lifted synchronously. The lower end of the filling column 51 disengages from the discharge port 42, the channel opens, and under the continued vibration, the tea leaves slide quickly into the discharge port 42 along the guide frame 113 and are finally discharged from the guide frame 113, completing a fully automatic and evenly stir-fried tea leaf stir-frying operation.
