Technical Field
[0001] This utility model relates to the technical field of tea color sorting machines, specifically a tea color sorting machine with uniform and continuous feeding. Background Technology
[0002] A tea color sorter is a high-tech optoelectronic mechanical device that uses the color difference between tea stems, yellow leaves, and genuine tea leaves to select the best quality tea leaves using a high-definition CCD optical sensor. The tea leaves enter the machine from the top hopper. Vibration from the vibrator causes the selected material to slide down the channel and accelerate into the observation area of the sorting chamber. The tea leaves pass between the sensor and the background plate. Under the influence of a light source, the system generates an output signal based on the intensity and color change of the light, which drives the solenoid valve to blow out the tea leaves of different colors into the waste chamber of the receiving hopper. The good tea leaves continue to fall into the finished product chamber of the receiving hopper, thus achieving the purpose of sorting.
[0003] The prior art, disclosed in CN217250748U, provides a tea color sorter with continuous feeding capability, comprising a base and a color sorting chamber. The color sorting chamber is fixedly mounted on the base, and locking casters are evenly installed at the four corners of the base's bottom. Color sorting components and a discharge pipe are sequentially installed on the sides of the color sorting chamber. A receiving hopper is fixed to the upper part of the color sorting chamber, and two mounting frames are movably mounted on the receiving hopper. Several reinforcing beams are spaced apart above the two mounting frames, with each reinforcing beam fixedly connected to both ends of the two mounting frames. Rectangular through-holes for the movement of a strip conveyor track are provided on the bottom sides of both mounting frames. This application replaces manual feeding with a machine, ensuring a stable feeding quantity and achieving continuity that cannot be achieved during manual rest, freeing workers' hands and significantly reducing their labor intensity.
[0004] In the aforementioned patent, the tea leaves are mainly pushed from the strip-shaped conveyor track into the receiving hopper by a driven pusher plate through the activation of the conveyor belt. However, since the tea leaves are continuously laid flat on the strip-shaped conveyor track, and the pusher plate on the conveyor belt pushes the tea leaves at intervals, the pusher plate cannot push all the tea leaves on the strip-shaped conveyor track into the receiving hopper, resulting in waste of tea leaves and reducing the practicality of the continuously feeding tea color sorter. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tea color sorter with uniform and continuous feeding, thus solving the above-mentioned technical problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tea color sorter with uniform and continuous feeding, comprising a base plate, on which a screening component for tea color measurement and sorting is fixedly mounted. A controller for controlling the internal electronic components of the tea color sorter is fixedly mounted on one side of the base plate. A feeding component for continuous and uniform feeding of tea is fixedly mounted on the side of the screening component away from the base plate. The feeding component includes a connecting plate fixedly mounted on the screening component. An upper hollow opening for placing tea is fixedly mounted on the end of the connecting plate away from the screening component. A lower hollow opening for tea to fall is connected below the upper hollow opening. A pushing component for pressing the tea in the upper hollow opening is fixedly mounted on the top of the connecting plate. The pushing component on the top of the connecting plate allows the pushing component to evenly push the tea downwards from the upper hollow opening, improving the uniformity of tea falling in the uniform and continuous feeding tea color sorter.
[0007] Furthermore, the pushing assembly includes an electric push rod fixedly mounted on a connecting plate. A strip is fixedly mounted on the end of the electric push rod away from the connecting plate. A connecting shaft is fixedly mounted on the side of the strip away from the electric push rod. A push plate is fixedly mounted on the end of the connecting shaft away from the strip. The size of the push plate is adapted to the size of the inner groove of the upper hollow opening. This adaptation allows the push plate to precisely enter the upper hollow opening and complete the pushing of the tea leaves, improving the comprehensiveness of tea leaf pushing in the uniformly and continuously fed tea color sorter.
[0008] Furthermore, the screening component includes a hollow channel, with a feed hopper fixedly connected to the top of the hollow channel. The lower hollow opening is located directly above the feed hopper, and the hollow channel communicates with the interior of the feed hopper. This communication between the hollow channel and the feed hopper allows tea leaves falling into the feed hopper to directly enter the hollow channel, improving the smoothness of tea leaf falling within the uniformly and continuously fed tea color sorter.
[0009] Furthermore, a first collection box for collecting normal tea leaves is fixedly connected to one end of the hollow channel away from the feed hopper. The first collection box is located on the bottom plate. A hollow curved channel is fixedly installed in the middle of the hollow channel. The curved channel is connected to the interior of the hollow channel. A second collection box for collecting different types of tea leaves is fixedly connected to the bottom of the curved channel. The second collection box is located on the bottom plate.
[0010] Furthermore, a mounting frame is fixedly installed at the end of the hollow channel away from the curved channel. A blower is fixedly connected to the mounting frame and electrically connected to the controller. The blower is used to blow foreign tea leaves into the curved channel, and the blower's outlet corresponds to the connection port between the curved channel and the hollow channel. This alignment of the blower's outlet with the connection port allows the blower to effectively blow foreign tea leaves into the curved channel, improving the practicality of the tea color sorter with uniform and continuous feeding.
[0011] Furthermore, a colorimetric component is fixedly installed at one end of the hollow channel near the controller. The centerline of the colorimetric component is on the same plane as the centerline of the blower, and the colorimetric component is electrically connected to the controller. This electrical connection allows the controller to directly control the colorimetric component, improving the intelligence of the tea color sorter's uniform and continuous feeding operation.
[0012] Furthermore, the color measurement component includes a fixed frame fixedly installed on the hollow channel, an optical sensor for tea color detection is fixedly installed at the center of the fixed frame, and a connecting wire is fixedly connected to the end of the optical sensor away from the hollow channel. The optical sensor is electrically connected to the controller through the connecting wire. Beneficial effects
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention places all the tea leaves into the upper hollow opening. Because the upper hollow opening is narrower than the lower hollow opening, not all the tea leaves will fall into the feed hopper. In conjunction with the electric push rod that pushes the push plate downwards, the tea leaves in the upper hollow opening are squeezed downwards, allowing them to fall evenly and continuously into the feed hopper. This ensures that the tea leaves are completely and evenly fed into the screening components for color measurement and screening, thus improving the practicality of the tea color sorter.

[0023] Example
[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6This application provides a further detailed description. A tea color sorter with uniform and continuous feeding includes a base plate 1. A screening component 2 for tea color measurement and screening is fixedly mounted on the base plate 1. A controller 3 for controlling the internal electronic components of the tea color sorter is fixedly mounted on one side of the base plate 1. A feeding component 4 for continuous and uniform feeding of tea is fixedly mounted on the side of the screening component 2 away from the base plate 1. The feeding component 4 includes a connecting plate 43 fixedly mounted on the screening component 2. An upper hollow opening 41 for placing tea is fixedly mounted on the end of the connecting plate 43 away from the screening component 2. A lower hollow opening 42 for tea to fall is connected below the upper hollow opening 41. A pressing device for pressing the upper hollow opening is fixedly mounted on the top of the connecting plate 43. The tea-pushing assembly 44 includes an electric push rod 444 fixedly mounted on a connecting plate 43. A strip 443 is fixedly mounted at the end of the electric push rod 444 away from the connecting plate 43. A connecting shaft 442 is fixedly mounted on the side of the strip 443 away from the electric push rod 444. A push plate 441 is fixedly mounted at the end of the connecting shaft 442 away from the strip 443. The size of the push plate 441 is adapted to the size of the inner groove of the upper hollow opening 41. The screening assembly 2 includes a hollow channel 25. A feed hopper 26 is fixedly connected to the top of the hollow channel 25. The lower hollow opening 42 is located directly above the feed hopper 26. The hollow channel 25 communicates with the interior of the feed hopper 26. A first collection box 22 for normal tea collection is fixedly connected to the end of the hollow channel 25 away from the feed hopper 26. The first collection box 22 is located on the base plate 1. A hollow curved channel 27 is fixedly installed in the middle of the hollow channel 25. The curved channel 27 is connected to the interior of the hollow channel 25. A second collection box 28 for collecting non-standard tea is fixedly connected to the bottom of the curved channel 27. The second collection box 28 is located on the base plate 1. An installation frame 23 is fixedly installed at the end of the hollow channel 25 away from the curved channel 27. A blower 21 is fixedly connected to the installation frame 23. The blower 21 is electrically connected to the controller 3. The blower 21 is used to blow non-standard tea into the curved channel 27. The air outlet of the blower 21 corresponds to the connection port of the curved channel 27 and the hollow channel 25. A color measuring component 24 is fixedly installed at the end of the hollow channel 25 near the controller 3. The center line of the color measuring component 24 is on the same plane as the center line of the blower 21. The color measuring component 24 is electrically connected to the controller 3. The color measuring component 24 includes a fixed frame 241 fixedly installed on the hollow channel 25. An optical sensor 242 for tea color detection is fixedly installed at the center of the fixed frame 241. A connecting line 243 is fixedly connected to the end of the optical sensor 242 away from the hollow channel 25. The optical sensor 242 is electrically connected to the controller 3 through the connecting line 243.
[0025] The working principle of controller 3 can be divided into four basic steps: input, processing, output, and feedback. First, controller 3 receives input signals from external devices or users, such as button presses or information detected by sensors. Next, controller 3 processes the input signals, performs calculations and judgments according to the set algorithms and logic, and then generates corresponding output signals based on the processing results to control the working status and display information of external devices. Since controller 3 is electrically connected to blower 21, optical sensor 242, and electric push rod 444 through connecting wires, users can directly control the electronic components inside the tea color sorter that is feeding tea evenly and continuously through controller 3.
[0026] It should be noted that the electrical components and control components in this application are all connected to an external controller and are all existing technologies. This application has not improved them and does not affect the integrity of this application. Furthermore, the parts not involved or not disclosed in detail are the same as or implemented using existing technologies.
[0027] Since the center lines of the curved channel 27, the blower 21, and the color measuring component 24 are all located on the same plane, when the color measuring component 24 detects that the tea color is incorrect, it can quickly start the blower 21 through the controller 3. The operation of the blower 21 can blow the tea with incorrect color into the curved channel 27, which improves the intelligence of the tea color sorter with uniform and continuous feeding.
[0028] The working principle of blower 21 is mainly based on fluid dynamics. It increases the pressure of air or gas by reducing the space. The working process of the blower includes three key steps: first, air is drawn in through the air inlet; second, the rotating impeller compresses the internal air; and finally, the compressed air is discharged. In addition, centrifugal blowers use a high-speed rotating rotor and centrifugal force to flow air from the casing to the outlet, creating a certain air pressure. Roots blowers use a pair of meshing rotors to compress gas and push it to the exhaust port. Therefore, when the blower is running, it can blow all the tea leaves at the air outlet into the curved channel 27, and finally drop them into the second collection box 28 for collection.
[0029] The optical sensor 242 works by using the principle that when light shines on a photosensitive element, the energy of the photons excites electrons, causing a change in current or voltage within the photosensitive element, thus enabling the detection and measurement of light. The basic principle of the photoelectric sensor is based on the photoelectric effect, converting the change in the measured quantity into a change in the light signal. Then, with the help of photoelectric elements, the non-electrical signal is further converted into an electrical signal. Therefore, when the optical sensor 242 detects that the color of the tea leaves in the current detection area differs from the normal tea color, it can directly transmit the electrical signal to the controller 3, improving the efficiency of triggering the internal electronic components of the uniformly and continuously fed tea color sorter.
[0030] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the uniformly and continuously fed tea color sorter are fixed by threads. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the diagram. When using the uniformly and continuously fed tea color sorter, the user places all the tea leaves requiring color detection and sorting into the upper hollow opening 41. Because the lower hollow opening 42 is narrower and the tea leaves accumulate on it, the tea leaves will not fall directly. At this time, the optical sensor 242 is activated. Then, the user activates the electric push rod 444 via the controller 3. The electric push rod 444 can directly drive the push plate 441 downwards through the connecting shaft 442, pushing the tea leaves in the upper hollow opening 41 towards the lower hollow opening 42. At this time, the tea leaves will pass through the lower hollow opening 42 uniformly and continuously. The tea leaves fall into the feed hopper 26 through the hollow channel 42. When the tea leaves pass through the optical sensor 242, the optical sensor 242 directly detects the color of the tea leaves. When the color of the tea leaves is normal, the tea leaves will fall into the first collection box 22 through the hollow channel 25 for collection. When the optical sensor 242 detects that the color of the tea leaves is abnormal, it will quickly transmit an electrical signal to the controller 3. The controller 3 will quickly start the blower 21 to blow the tea leaves with abnormal color into the curved channel 27 and fall into the second collection box 28. This completes the detection and screening of the tea leaves. Through the cooperation of the above structure, the tea color sorter with uniform and continuous feeding can perform efficient color detection and screening of tea leaves while ensuring that all tea leaves are fed uniformly and continuously, thus improving the practicality of the tea color sorter with uniform and continuous feeding.
[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
