Description

Technical Field

[0001] This utility model relates to the technical field of tea processing, specifically a three-layer tea color sorter that prevents residue buildup. Background Technology

[0002] A tea color sorter is an intelligent sorting device based on machine vision and artificial intelligence technologies. It is mainly used for grading and sorting in the tea industry. Its working principle is to capture images of tea leaves through a camera and transmit them to a high-speed image processing chip. Advanced algorithms are used to quickly process and analyze the images to identify different components in the tea leaves, such as color, shape, size, and texture. The analysis results are then output to the control system, which makes corresponding judgments and processes based on these results to achieve automatic sorting of tea leaves. The tea color sorter mainly consists of a camera, an image processing chip, a control system, a robotic arm, and a sorting system.

[0003] Existing tea color sorters have certain shortcomings in use. During the flow and transfer of tea, due to the relatively large quantity of tea leaves and their tendency to stick together, tea leaves on the inside or that are obscured cannot be photographed, causing them to move downwards directly without accurate and sufficient color sorting. To solve the above defects, a multi-layer intelligent tea color sorter disclosed in the prior art (Chinese patent application number CN202322320585.2, publication date 2024-04-09) can be referenced. This color sorter sets a pneumatic separation channel in the middle of the photoelectric screening channel. The pneumatic separation channel is equipped with symmetrical LED lights on the upper and lower sides, which work in conjunction with photoelectric sensors. When sorting tea leaves, the leaves are fully separated to ensure the accuracy of tea color sorting. At the same time, two layers of LED lights and photoelectric sensors are set to further increase the sufficiency of color sorting.

[0004] Although the above-mentioned device can solve the problem of color sorting of tea currently available on the market, during the color sorting process, the tea leaves slide down due to their own gravity, but some tea leaves cannot be discharged in time, resulting in tea leaves remaining in the color sorting cylinder and thus wasting some tea leaves.

[0005] Therefore, we proposed a three-layer tea color sorter with anti-residue properties that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a three-layer tea color sorter that prevents residue, in order to solve the problem mentioned in the background art that the current color sorters on the market rely on the weight of the tea leaves to slide down during operation, but some tea leaves cannot be discharged in time, resulting in tea leaves remaining in the color sorting cylinder and thus wasting some tea leaves.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a three-layer tea color sorter with residue prevention, comprising a color sorting box, an inlet at the top of the color sorting box, an outlet at the bottom of the color sorting box, and a control panel mounted on the surface of the color sorting box; a fixed motor is fixed at the top of the color sorting box, the output end of the fixed motor is fixed outside the material distribution mechanism, and the operation of the material distribution mechanism can drive the rotating gear ring to rotate inside the color sorting box, which can perform preliminary color sorting treatment on the transparent first color sorting cylinder; the bottom of the first color sorting cylinder is connected to a material distribution cylinder, the bottom of the material distribution cylinder is connected to the top of the second color sorting cylinder, and the bottom of the second color sorting cylinder is connected to the top of the third color sorting cylinder.

[0008] As a preferred technical solution of this application, a color sorter, a light guide plate and an optical sensor are provided inside the second color sorter and the third color sorter, and the bottom of the third color sorter is connected to the discharge port.

[0009] As a preferred technical solution of this application, discharge ports are provided on both sides of the two sets of second color sorting cylinders, and an air pump is installed between the inner sides of the two sets of second color sorting cylinders. The output end of the air pump is connected to the middle of the air jet pipe, and the two ends of the air jet pipe extend into the inner sides of the two sets of second color sorting cylinders respectively, so as to discharge the tea leaves inside the air jet pipe.

[0010] As a preferred technical solution of this application, the material sorting mechanism includes a rotating gear fixed to the output end of a fixed motor. The outer side of the rotating gear is meshed with the outer side of a connecting gear. The outer edge of the connecting gear is rotatably disposed inside the first color sorting cylinder. The center of the connecting gear is fixed at the top of the material sorting plate. The end of the rotating gear away from the connecting gear is meshed with the inner side of a rotating gear ring. A color sorter is fixed at the bottom edge of the rotating gear ring.

[0011] As a preferred technical solution of this application, the color sorter is inclined, and the inner side of the color sorter corresponds to the outer side of the first color sorting cylinder, and the top position of the rotating toothed ring is rotatably disposed on the inner top of the color sorting box.

[0012] As a preferred technical solution of this application, the upper connection of the first color sorting cylinder near the distribution cylinder is separated by a partition plate to facilitate the diversion of tea leaves and speed up the color sorting efficiency. The outer side of the distribution plate is rotatably arranged on the inner side of the first color sorting cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This three-layer tea color sorter with anti-residue feature is equipped with a material distribution mechanism. Through this mechanism, the material inside the first color sorting cylinder is agitated by the distribution plate, and further divided by the rotation of the color sorter. This separation by the dividing plate prevents material residue from remaining inside the first color sorting cylinder. Furthermore, the three-layer color sorting process ensures thorough color sorting of the tea leaves. Specific details are as follows:

[0014] 1. A connecting gear is provided. The rotation of the connecting gear drives the rotating gear to mesh and rotate, so that the material distribution plate inside the connecting gear rotates in the first color sorting cylinder, thereby agitating the material and preventing residue. Furthermore, a rotating gear ring is provided. The rotating gear ring rotates through the rotating gear, thereby driving the color sorter to rotate, so that the color sorter performs preliminary color sorting on the outer side of the first color sorting cylinder.

[0015] 2. A first color sorting cylinder, a second color sorting cylinder, and a third color sorting cylinder are set up. Through the three-layer color sorting process, the tea leaves can be fully sorted. Furthermore, the air is supplied to the jet pipe by an air pump, so that the tea residue can be discharged through the discharge port. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-6 The present invention provides the following technical solution:

[0025] Example 1

[0026] To address the issue of current color sorters on the market where tea leaves slide down due to gravity, but some leaves remain inside the sorting cylinder and are wasted, please refer to the attached document. Figure 1 - Appendix Figure 3 and attached Figure 6 The bottom of the first color sorting cylinder 8 is connected to the distribution cylinder 13. The bottom of the distribution cylinder 13 is connected to the top of the second color sorting cylinder 14, and the bottom of the second color sorting cylinder 14 is connected to the top of the third color sorting cylinder 16. A color sorter 12, a light guide plate, and an optical sensor are installed inside the second color sorting cylinder 14 and the third color sorting cylinder 16. The bottom of the third color sorting cylinder 16 is connected to the discharge port 3. Discharge ports 15 are opened on both sides of the two sets of second color sorting cylinders 14. An air pump 17 is installed between the inner sides of the two sets of second color sorting cylinders 14. The output end of the air pump 17 is connected to the middle of the air jet pipe 18. The two ends of the air jet pipe 18 extend into the inner sides of the two sets of second color sorting cylinders 14 to discharge the tea leaves inside the air jet pipe 18.

[0027] As tea leaves fall into the first color sorting cylinder 8, the material undergoes initial color sorting by the color sorter 12. The material is then diverted through the distribution cylinder 13, and the remaining material falls into the second color sorting cylinder 14. Inside the second color sorting cylinder 14, the tea leaves undergo further color sorting via the color sorter 12, light guide plate, and optical sensor. At this point, the air pump 17 is activated, delivering gas to the jet pipe 18 to agitate the tea residue inside the second color sorting cylinder 14. The residue is then discharged through the outlet 15. Finally, the tea leaves undergo a third color sorting process in the third color sorting cylinder 16. This three-stage color sorting process allows for more efficient processing.

[0028] Example 2

[0029] To expedite the internal tea color sorting process, please refer to the attached document. Figure 1 - Appendix Figure 5 The system includes a color sorting box 1, a feed inlet 2 at the top of the color sorting box 1, a discharge outlet 3 at the bottom of the color sorting box 1, and a control panel 4 mounted on the surface of the color sorting box 1. A fixed motor 5 is fixed at the top of the color sorting box 1, and the output end of the fixed motor 5 is fixed to the outside of the distributing mechanism. The operation of the distributing mechanism can drive the rotating gear ring 11 to rotate inside the color sorting box 1, which can perform preliminary color sorting treatment on the transparent first color sorting cylinder 8. The distributing mechanism includes a rotating gear 6 fixed to the output end of the fixed motor 5. The outer side of the rotating gear 6 is meshed with the outer side of the connecting gear 7. The outer edge of the connecting gear 7 is rotatably set on the first color sorting cylinder 8. Inside the sorting cylinder 8, the center of the connecting gear 7 is fixed at the top of the distribution plate 9. The end of the rotating gear 6 away from the connecting gear 7 is meshed with the inner side of the rotating gear ring 11. A color sorter 12 is fixed at the bottom edge of the rotating gear ring 11. The color sorter 12 is inclined, and the inner side of the color sorter 12 corresponds to the outer side of the first color sorting cylinder 8. The top of the rotating gear ring 11 is rotatably set at the top of the inner side of the color sorting box 1. The upper end of the first color sorting cylinder 8 near the distribution cylinder 13 is separated by a partition plate 10 to divert the tea leaves and speed up the color sorting efficiency. The outer side of the distribution plate 9 is rotatably set inside the first color sorting cylinder 8.

[0030] First, appropriate tea leaves are fed into the outlet 3. Then, the fixed motor 5 is started by controlling the control panel 4. The output of the fixed motor 5 drives the rotating gear 6 to rotate at the top inner side of the color sorting box 1. The rotating gear 6 then drives the meshing connecting gear 7 to rotate inside the first color sorting cylinder 8. The center end of the connecting gear 7 drives the distributing plate 9 to rotate, which in turn rotates inside the first color sorting cylinder 8. The distributing plate 9 slowly moves the tea leaves. While the rotating gear 6 is rotating, the connecting gear 7 also drives the rotating gear ring 11 to rotate. The rotating gear ring 11 rotates stably at the top inner side of the color sorting box 1, causing the color sorter 12 to perform preliminary color sorting on the tea leaves inside the first color sorting cylinder 8.
