Description

Technical Field

[0001] This utility model belongs to the field of tea processing technology, and specifically relates to an electrostatic impurity removal machine for tea. Background Technology

[0002] The processing of Liubao tea is a complex and multi-step process, encompassing multiple stages from harvesting to the finished product. Primary processing includes steps such as fixation, rolling, piling, re-rolling, drying, and impurity removal. Refined processing includes steps such as screening, blending, piling, steaming, pressing, and aging. The processing of Liubao tea not only embodies the essence of traditional techniques but also integrates modern technology and scientific methods, resulting in superior quality.

[0003] The removal of impurities from Liubao tea is mainly achieved using an electrostatic impurity remover, which is a device based on electrostatic sorting technology. It utilizes the differences in electrical properties (such as conductivity and dielectric constant) between tea leaves and impurities, subjecting them to different electric forces in a high-voltage electrostatic field, thereby achieving the separation of tea leaves from impurities.

[0004] In existing electrostatic tea cleaning machines, the electrostatic roller is mounted on the vibrating feeder via bearings. Since the electrostatic roller is fixed relative to the vibrating feeder, it may cause the tea leaves to be crushed or fail to make effective contact with the tea leaves. The electrostatic roller crushing the tea leaves will damage them, while the electrostatic roller failing to make effective contact with the tea leaves will result in the tea leaves and impurities not being effectively separated, thus failing to achieve the effect of removing impurities.

The embodiments of this utility model will now be described based on its overall structure.

[0031] Example 1 like Figure 1-4 As shown, this embodiment provides a tea electrostatic impurity removal machine, comprising: Feeding conveyor belt 1, feeding conveyor belt 1 is equipped with a material leveling shaft 2, the material leveling shaft 2 is perpendicular to the movement direction of belt 15 of feeding conveyor belt 1; A vibrating feeding mechanism, one end of which is located below the end of the feeding conveyor belt 1; The height adjustment component 3 is a multiple height adjustment component 3, which is divided into two groups. The two groups of height adjustment components 3 are installed on both sides of the vibrating feeding mechanism. Each group of height adjustment components 3 is distributed at intervals on the vibrating feeding mechanism, and the two groups of height adjustment components 3 correspond one-to-one. There are multiple electrostatic rollers 4, each of which is rotatably mounted on two corresponding height adjustment components 3. The electrostatic rollers 4 are the existing electrostatic impurity removal machines for tea, which are existing products. How they generate static electricity to adsorb impurities is existing technology and will not be elaborated on here. Impurity cleaning component 5: One impurity cleaning component 5 is provided on one side of each electrostatic roller 4. The impurity cleaning component 5 is used to clean impurities on the surface of the electrostatic roller 4. Collection container 6 is located below the end of the vibrating feeding mechanism.

[0032] The surface of the belt 15 of the feed conveyor belt 1 is provided with an array of protrusions 8. By setting the protrusions 8, the friction between the tea leaves and the surface of the belt 15 is increased.

[0033] The belt 15 of the feed conveyor belt 1 is inclined, with the end closer to the vibrating feeding mechanism higher than the end farther away from the vibrating feeding mechanism. This arrangement initially removes metal or stones mixed in with the tea leaves, based on the principle that the metal or stones themselves slide off as the belt 15 is inclined.

[0034] A first drive motor 9 is installed on one side of the feeding conveyor belt 1, and the output shaft of the first drive motor 9 is connected to the material leveling shaft 2. Specifically, the material leveling shaft 2 is an existing tea leaf dispersing roller shaft, which mainly consists of a rotating shaft 10 and dispersing teeth 11 uniformly fixed on the rotating shaft 10. It is driven by the first drive motor 9, which is started by connecting to a power source.

[0035] The vibrating feeding mechanism includes a support frame, a vibrating motor, and a feeding plate 14. The vibrating motor is mounted on the support frame, and its output shaft is connected to the feeding plate 14. The feeding plate 14 is connected to the support frame via a spring. The feeding plate 14 has an array of sieve holes. By providing sieve holes on the feeding plate 14, stones mixed in with the tea leaves will fall directly through the sieve holes, further removing impurities from the tea leaves.

[0036] The height adjustment assembly 3 includes a fixed block 20, an adjusting block 21, an adjusting screw 26, and a bearing seat 24. The fixed block 20 is fixed on the vibrating feeding mechanism. A hinge shaft is provided at the top of one end of the fixed block 20. One end of the adjusting block 21 is connected to the hinge shaft through a bushing 22. The bearing seat 24 is installed on the top of the adjusting block 21. The electrostatic roller 4 is rotatably connected to the bearing seat 24 through a bearing. The adjusting screw 26 is threadedly connected to the adjusting block 21 and rotatably connected to the fixed block 20. Specifically, the adjusting block 21 is connected to the hinge shaft via the bushing 22, thereby enabling the adjusting block 21 to swing relative to the fixed block 20. The side of the adjusting block 21 is provided with a sliding groove 23, and a slider 25 is slidably connected to the sliding groove 23. The slider 25 is provided with a threaded hole, and the adjusting screw 26 is threadedly connected to the threaded hole. The top of the adjusting screw 26 is provided with a rotating ring for easy rotation by the operator. The adjusting screw 26 is rotatably connected to the fixed block 20 via a bearing. When the operator rotates the adjusting screw 26, the slider 25 moves axially along the adjusting screw 26 and slides along the sliding groove 23. The adjusting block 21 moves with the slider 25, thereby slightly adjusting the height of the electrostatic roller 4 relative to the feeding plate 14. For example, it can be adjusted to 1-10mm, which is suitable for different types of tea with different moisture contents.

[0037] The impurity cleaning assembly 5 includes a scraper 18, a collection hopper 17, a first collection trough 13, and a second collection trough 12. One side of the scraper 18 is in contact with the surface of the electrostatic roller 4. Both ends of the collection hopper 17 are fixedly mounted on the height adjustment assembly 3 (specifically, mounted on the adjustment block 21, and supported by the support plate 19, so that the collection hopper 17 can be adjusted along with the electrostatic roller 4 when the adjustment block 21 is adjusted). Both sides of the collection hopper 17 are open structures. The two ends of the scraper 18 are fixed at the opening on one side of the collection hopper 17, and part of the opening edge of the collection hopper 17 is located below the scraper 18. The opening on the other side of the collection hopper 17 is located above the first collection trough 13, and the outlet of the first collection trough 13 is located above the second collection trough 12. Both the first collection trough 13 and the second collection trough 12 are mounted on the vibrating feeding mechanism. It should be noted that the contact position between the scraper 18 and the surface of the electrostatic roller 4 is at the edge of the electrostatic roller 4 at the maximum cross-sectional radius in the horizontal plane. The edge of part of the opening of the collection hopper 17 is located below the contact position between the scraper 18 and the electrostatic roller 4, so that the impurities scraped off by the scraper 18 can be collected and fall into the first collection trough 13 through the opening on the other side. The first collection trough 13 then transports the impurities to the second collection trough 12. The transport method can be that the impurities are manually moved to the second collection trough 12 after the machine stops, or they can be tilted and automatically slide into the second collection trough 12 by gravity.

[0038] The electrostatic tea cleaning machine also includes a drive mechanism, which comprises a second drive motor, a first pulley 16, and a belt 15. Each electrostatic roller 4 is connected to a second pulley, and all the second pulleys are connected to the belt 15. The first pulley 16 is connected to the output shaft of the second drive motor, and the first pulley 16 is also connected to the belt 15. The second drive motor is an existing motor that starts upon connection to a power source. It only needs to be able to drive the first pulley 16 to rotate, which in turn drives the belt 15, which in turn drives all the second pulleys to rotate. With this configuration, the rotation speed of the electrostatic roller 4 can be adjusted by regulating the output power of the second drive motor, thus adapting to different types of tea with different moisture contents.

[0039] Magnets are installed on the feeding plate 14. By setting up magnets, metals mixed in with the tea leaves that can be attracted by magnets can be effectively adsorbed, further removing impurities from the tea leaves.

[0040] A dust cover 7 is installed on the top of the support frame. Considering that some workshops are not cleanrooms, a dust cover is installed on the outside of the support frame to prevent dust from entering the electrostatic roller 4 and the feeding plate 14. Considering that there are workers walking around in cleanrooms and there may be hair or other impurities, even in cleanrooms, the dust cover 7 can effectively protect hair or other impurities from entering the electrostatic roller 4 and the feeding plate 14.

[0041] Example 2 like Figure 5 As shown, the height adjustment component 3 in this embodiment includes a third drive motor 27 and a screw. The third drive motor 27 is mounted on a support frame, and the screw is connected to the output shaft of the third drive motor 27. A connecting seat 28 is connected to the screw, and the connecting seat 28 is connected to the electrostatic roller 4 through a bearing seat 24. The electrostatic roller 4 is rotatably connected to the bearing seat 24 through a bearing. Although this configuration increases the cost, it enables automated adjustment.
