Description
An automated tea sorting device Technical Field
[0001] This invention relates to the field of tea production and processing technology, and in particular to an automated tea sorting device. Background Technology
[0002] As the demand for tea increases, consumers are also raising their quality requirements. Traditional tea picking is done manually, resulting in low production efficiency. Currently, mechanized picking is widely used, significantly improving labor efficiency and reducing production costs. However, machine-picked tea is susceptible to factors such as tea variety and equipment performance, making it difficult to achieve high-quality tea under current processing methods. Tea sorting is necessary to remove impurities and improve quality. For tea sorting equipment, refer to the Chinese utility model patent application number 202122294489.6, entitled "Tea Sorting Device with Dust Collection Function." Current tea sorting equipment has limited adjustability and a single form, failing to fully leverage the advantages of tea sorting to meet society's demand for high-quality tea, achieve non-destructive high-quality detection and automated processing, and ensure the integrity and high quality of the tea leaves. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide an adjustable automated tea sorting device to improve the versatility of the tea sorting device and the tea sorting accuracy.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automated tea sorting device, comprising:
[0005] The frame is equipped with a tea conveyor belt;
[0006] An electrostatic sorting assembly, comprising three or more sets of such electrostatic sorting assemblies, is spaced apart on a frame along the conveying direction of the tea conveyor belt. Each electrostatic sorting assembly includes a lifting frame, an electrostatic rotating roller, a baffle, and a receiving trough. The lifting frame is slidably mounted on the frame in a vertical direction. The electrostatic rotating roller, baffle, and receiving trough are arranged parallel to each other on the lifting frame. The electrostatic rotating roller is located above the tea conveyor belt, and the gap between the electrostatic rotating roller and the tea conveyor belt gradually decreases along the conveying direction of the tea conveyor belt. The baffle abuts against the electrostatic rotating roller, and the receiving trough is located below the baffle.
[0007] Furthermore, the frame is provided with a vertical guide rail and an adjusting screw, the lifting frame is slidably connected to the vertical guide rail, the adjusting screw is rotatably mounted on the frame, and the adjusting screw is threadedly connected to the lifting frame.
[0008] Furthermore, the electrostatic sorting assembly also includes a drive motor and friction cotton, both of which are mounted on the lifting frame. The drive motor is connected to the electrostatic rotating roller, and the friction cotton abuts against the electrostatic rotating roller.
[0009] Furthermore, the baffle is provided with a brush that abuts against the electrostatic rotating roller.
[0010] Furthermore, the receiving trough is equipped with a vibrating feeding module.
[0011] Furthermore, the electrostatic sorting assembly also includes a collection bin, and the outlet of the receiving trough is connected to the collection bin.
[0012] Furthermore, it also includes a vibration sorting assembly, which includes a screen, a vibrator, and a receiving hopper. The screen is inclinedly mounted on the frame, and the vibrator is mounted on the screen. The mesh size of the screen increases sequentially from high to low. Two or more sets of the receiving hoppers are arranged side by side below the screen, and each receiving hopper is connected to a tea conveyor belt.
[0013] Furthermore, the tilt angle of the screen ranges from 10° to 25°.
[0014] Furthermore, it also includes an air separation component, which includes a housing and a fan. The housing is hollow inside, with a feed inlet at the top of the housing. The fan is mounted on the side wall of the housing, and two or more discharge hoppers are located at the bottom of the housing. A screen is installed at the discharge port of each discharge hopper.
[0015] Furthermore, the bottom plate of the box is provided with a partition between two adjacent discharge hoppers.
[0016] The beneficial effects of this invention are as follows: An automated tea sorting device includes two or more sets of electrostatic sorting components installed above the tea conveyor belt on a frame. Each electrostatic sorting component has a lifting frame that can be vertically raised and lowered on the frame. After movement, the lifting frame is locked and fixed to the frame by fasteners, thereby controlling the distance between the electrostatic rotating roller and the tea conveyor belt. Since the gap between the electrostatic rotating roller and the tea conveyor belt gradually decreases along the conveying direction of the tea conveyor belt, small, lightweight tea leaves are attracted by the front electrostatic rotating roller, while large, heavy tea leaves are attracted by the rear electrostatic rotating roller. The attracted tea leaves rotate with the electrostatic rotating roller until they are blocked by a baffle and fall into the corresponding receiving trough, thus completing the sorting. The automated tea sorting device provided by this invention has a flexible and adjustable structure, which can adapt to the sorting of various types of tea. Especially when the size and weight differences of the tea leaves are small, it can accurately classify the tea leaves, which is beneficial to improving the quality of the tea.

[0027] This invention provides an automated tea sorting device, which is used in automated tea sorting operations.
[0028] Please refer to Figures 1 to 4. An automated tea sorting device of the present invention includes:
[0029] Frame 1, wherein the frame 1 is equipped with a tea conveyor belt 11;
[0030] Electrostatic sorting assembly 2, three or more sets of electrostatic sorting assemblies 2 are arranged at intervals on the frame 1 along the conveying direction of the tea conveyor belt 11. The electrostatic sorting assembly 2 includes a lifting frame 21, an electrostatic rotating roller 22, a baffle 23 and a receiving trough 24. The lifting frame 21 is slidably arranged on the frame 1 in the vertical direction. The electrostatic rotating roller 22, the baffle 23 and the receiving trough 24 are arranged parallel to each other on the lifting frame 21. The electrostatic rotating roller 22 is located above the tea conveyor belt 11. The gap between the electrostatic rotating roller 22 and the tea conveyor belt 11 gradually decreases along the conveying direction of the tea conveyor belt 11. The baffle 23 abuts against the electrostatic rotating roller 22. The receiving trough 24 is located below the baffle 23.
[0031] As can be seen from the above description, the beneficial effects of the present invention are as follows: An automated tea sorting device includes two or more sets of electrostatic sorting components 2 arranged above the tea conveyor belt 11 of a frame 1. Each electrostatic sorting component 2 has a lifting frame 21 that can be vertically raised and lowered on the frame 1. After movement, the lifting frame 21 is locked and fixed to the frame 1 by fasteners, thereby controlling the distance between the electrostatic rotating roller 22 and the tea conveyor belt 11. Since the gap between the electrostatic rotating roller 22 and the tea conveyor belt 11 gradually decreases along the conveying direction of the tea conveyor belt 11, small and lightweight tea leaves are adsorbed by the front electrostatic rotating roller 22, while large and heavy tea leaves are adsorbed by the rear electrostatic rotating roller 22. The adsorbed tea leaves rotate with the electrostatic rotating roller 22 until they are blocked by the baffle 23 and fall into the corresponding receiving trough 24, thus completing the sorting. The automated tea sorting device provided by the present invention has a flexible and adjustable structure, which can adapt to the sorting of various types of tea. Especially when the size and weight differences of the tea leaves are small, it can accurately classify the tea leaves, which is beneficial to improving the quality of the tea.
[0032] In an optional embodiment, the frame 1 is provided with a vertical guide rail 12 and an adjusting screw 13, the lifting frame 21 is slidably connected to the vertical guide rail 12, the adjusting screw 13 is rotatably mounted on the frame 1, and the adjusting screw 13 is threadedly connected to the lifting frame 21.
[0033] As can be seen from the above description, the vertical guide rail 12 plays a guiding and constraining role on the lifting frame 21. By adjusting the rotation of the screw 13, the horizontal height of the lifting frame 21 can be controlled, thereby controlling the distance between the electrostatic rotating roller 22 and the tea conveyor belt 11.
[0034] In an optional embodiment, the electrostatic sorting component 2 further includes a drive motor 25 and a friction cotton 26. The drive motor 25 and the friction cotton 26 are both mounted on the lifting frame 21. The drive motor 25 is connected to the electrostatic rotating roller 22, and the friction cotton 26 abuts against the electrostatic rotating roller 22.
[0035] As can be seen from the above description, the drive motor 25 is used to control the rotation speed of the electrostatic rotating roller 22, thereby adapting to the sorting of various types of tea.
[0036] In an optional embodiment, the baffle 23 is provided with a brush 231 that abuts against the electrostatic rotating roller 22.
[0037] As can be seen from the above description, the brush 231 is used to scrape off the tea leaves from the surface of the electrostatic rotating roller 22.
[0038] In an optional embodiment, the receiving trough 24 is provided with a vibrating feeding module.
[0039] As can be seen from the above description, the vibration feeding module includes a vibration generator, etc., to achieve vibration feeding.
[0040] In an optional embodiment, the electrostatic sorting component 2 further includes a collection bin 27, and the discharge port of the receiving trough 24 is connected to the collection bin 27.
[0041] As can be seen from the above description, the collection bucket 27 is used to store the tea leaves received and transported by the receiving trough 24, thereby completing the sorting.
[0042] In an optional embodiment, a vibration sorting component 3 is also included. The vibration sorting component 3 includes a screen 31, a vibrator 32, and a receiving hopper 33. The screen 31 is inclinedly arranged on the frame 1, and the vibrator 32 is arranged on the screen 31. The mesh size on the screen 31 increases from high to low. Two or more sets of receiving hoppers 33 are arranged side by side below the screen 31, and each receiving hopper 33 is connected to a tea conveyor belt 11.
[0043] As can be seen from the above description, the vibrating sorting component 3 vibrates the screen 31 through the vibrator 32, and the tea leaves are sorted out from top to bottom on the screen 31 to separate tea leaves of different sizes and stored in different receiving hoppers 33.
[0044] In an optional embodiment, the tilt angle of the screen 31 ranges from 10° to 25°.
[0045] As can be seen from the above description, if the tilt angle of the screen 31 is too large, the sorting accuracy will be reduced, and if the tilt angle of the screen 31 is too small, the sorting efficiency will be reduced.
[0046] In an optional embodiment, an air separation component 4 is also included. The air separation component 4 includes a housing 41 and a fan 42. The housing 41 is hollow inside. The top of the housing 41 is provided with a feed inlet. The fan 42 is disposed on the side wall of the housing 41. The bottom of the housing 41 is provided with two or more sets of discharge hoppers 43. A screen 31 is provided at the discharge port of each discharge hopper 43.
[0047] As can be seen from the above description, after the tea leaves are put into the box 41 through the feed inlet, the blower 42 blows the tea leaves of different weights to different distances, so that they fall into different discharge hoppers 43.
[0048] In an optional embodiment, the bottom plate of the box 41 is provided with a partition 44 between two adjacent discharge hoppers 43.
[0049] As can be seen from the above description, the partition 44 serves to separate the different discharge hoppers 43.
[0050] The working principle of this invention is as follows: tea leaves are sequentially sorted through the air separation component 4, the vibration separation component 3, and the electrostatic separation component 2 in multiple stages, completing the classification of different grades of tea leaves in one go. The overall structure of the device is reasonable, easy to adjust, and has good versatility.

[0055] In summary, the automated tea sorting device provided by this invention includes two or more sets of electrostatic sorting components installed above the tea conveyor belt on a frame. Each electrostatic sorting component has a lifting frame that can be vertically raised and lowered on the frame. After movement, the lifting frame is locked to the frame by fasteners, thereby controlling the distance between the electrostatic rotating roller and the tea conveyor belt. Since the gap between the electrostatic rotating roller and the tea conveyor belt gradually decreases along the conveying direction of the tea conveyor belt, small, lightweight tea leaves are attracted by the front electrostatic rotating roller, while large, heavy tea leaves are attracted by the rear electrostatic rotating roller.
