Description
Technical Field
[0001] This utility model relates to the field of electrostatic impurity removal technology for tea, specifically to an electrostatic impurity removal device for tea. Background Technology
[0002] White tea is a lightly fermented tea that is not subjected to pan-firing or rolling. It is simply naturally withered, sun-dried, or gently baked. It has intact buds covered in fine hairs, a clear yellow-green liquor, a sweet and mellow taste, a high floral aroma, and a rich honey fragrance. White tea contains caffeine, which can stimulate the central nervous system and have a stimulating effect. However, before packaging, the tea often contains impurities such as hair, straw, woven bag fibers, and plastic fragments, making the current production products quite unhygienic. Therefore, electrostatic purification devices are needed to remove these impurities.
[0003] Existing electrostatic impurity removal devices typically use electrostatic rollers to adsorb impurities from tea leaves. However, before passing through the electrostatic rollers, the tea leaves tend to accumulate in a thick layer in the conveying trough, hindering efficient impurity removal. Furthermore, after the electrostatic rollers adsorb impurities, these impurities tend to accumulate at the connection between the rollers and the feed trough, affecting the efficiency of electrostatic adsorption. Therefore, there is an urgent need to design an electrostatic impurity removal device for tea leaves to solve these problems. Utility Model Content
[0004] The purpose of this invention is to provide an electrostatic impurity removal device for tea leaves, so as to solve the above-mentioned shortcomings in the prior art.

Several electrostatic rollers 5 are rotatably inserted at equal intervals inside the base 1. A guide groove 6 is fixed on the top of the base 1 and one side of the guide groove 6 is in contact with the electrostatic rollers 5. A lead screw 7 is rotatably inserted inside the guide groove 6.

A vibrator 23 is fixed at the bottom of the conveying groove 2.
[0025] Specifically, in this embodiment, a base 1 is included. Several springs 26 are fixed inside the base 1. A conveying groove 2 is fixed to the end of each spring 26 away from the base 1, and the conveying groove 2 is inside the base 1. Under the action of the springs 26, the conveying groove 2 can dampen the vibration of the base 1 when the vibrator 23 vibrates. A hopper 3 is fixed to one side of the base 1.

A reciprocating motion component 25 is provided at one end of the spreading plate 4, and the reciprocating motion component 25 is fixed to the outer wall of one side of the base 1. Under the action of the reciprocating motion component 25, the spreading plate 4 can move left and right to spread the tea leaves passing under the bottom of the spreading plate 4. The interior of the base 1 is equidistant from each other. Several electrostatic rollers 5 are rotatably inserted, which can adsorb impurities in the tea leaves. A guide trough 6 is fixed on the top of the base 1, and one side of the guide trough 6 is in contact with the electrostatic rollers 5.

The scraper 8 can clean the impurities in the guide trough 6 under the drive of the motor 2. A vibrator 23 is fixed at the bottom of the conveying trough 2. The vibrator 23 can make the tea leaves slide out of the conveying trough 2 under the action of vibration.
[0026] The present invention provides a tea electrostatic impurity removal device, which, through the setting of a spreading plate 4, a vibrator 23 and a reciprocating motion component 25, allows the tea leaves to slide down the conveying trough 2 under the action of the vibrator 23 and pass through the bottom of the spreading plate 4. The spreading plate 4 moves left and right under the action of the reciprocating motion component 25, which disperses the thickly piled tea leaves and makes the tea leaves more evenly distributed in the conveying trough 2.
[0027] In one embodiment of this utility model, the repetitive motion component 25 includes a fixed base 20, a rotating shaft 16 fixed on one side of the fixed base 20, a sector gear 15 rotatably sleeved on the outside of the rotating shaft 16, a toothed plate 14 provided at the top of one end of the paving plate 4, and the sector gear 15 meshing with the toothed plate 14, a rocker arm 27 provided at the top of the sector gear 15, a guide hole 17 provided in the middle of the rocker arm 27, a second motor 19 fixed on the back of the fixed base 20, an eccentric wheel 18 fixed on the output shaft of the second motor 19, and a retaining pin of the eccentric wheel 18 inserted into the guide hole 17. Under the action of the second motor 19, the eccentric wheel 18 drives the rocker arm 27 to move, and the rocker arm 27 drives the sector gear 15 to rotate under the action of the rotating shaft 16, and then drives the paving plate 4 to move left and right under the action of the toothed plate 14.
[0028] In another embodiment of this utility model, a collection hopper 11 is fixed on one side of the outer wall of the conveying trough 2, and the collection hopper 11 is located below the discharge port of the guide trough 6. The impurities collected by the guide trough 6 will slide into the collection hopper 11 for easy collection. Standing feet 12 are provided at the corners of the base 1.
[0029] In another embodiment of this utility model, a felt 13 is provided on the side of the guide trough 6 that is in contact with the electrostatic roller 5, and the felt 13 is located below the scraper 8. The felt 13 generates static electricity by rubbing against the electrostatic roller 5, so that the electrostatic roller 5 can work normally.
[0030] In one embodiment of this utility model, a double-track pulley 24 is fixed at the center of one side of the electrostatic roller 5, and a motor 21 is fixed at the bottom of the base 1. The output shaft of the motor 21 is sleeved with a belt 22, and the end of the belt 22 away from the motor 21 is sleeved on the double-track pulley 24. Through the double-track pulley 24, the motor 21 and the adjacent electrostatic roller 5 can be connected by the belt 22.
[0031] In another embodiment of this utility model, the end of the scraper 8 away from the electrostatic roller 5 is engaged in the guide groove on the inner wall of the guide trough 6. The stability of the scraper 8 during operation can be ensured by engaging one end of the scraper 8 in the guide groove on the inner wall of the guide trough 6.
[0032] Working principle: In use, the vibrator 23 at the bottom of the conveying trough 2 is turned on, and the tea leaves are poured into the hopper 3. The tea leaves then slide from the hopper 3 into the conveying trough 2 under the vibration of the vibrator 23. They continue to slide down the conveying trough 2, passing under the spreading plate 4. The spreading plate 4 moves left and right under the action of the motor 19, gear 15, and toothed plate 14 in the reciprocating motion assembly 25, breaking up thicker piles of tea leaves and distributing them evenly. The evenly distributed tea leaves slide down to the electrostatic roller 5. The double-rail pulley 24 on the electrostatic roller 5, under the action of the motor 21 and belt 22, drives the electrostatic roller... As the roller 5 rotates, the electrostatic roller 5 generates static electricity through friction with the felt 13 during its rolling process. The electrostatic roller 5, carrying static electricity, adsorbs impurities in the tea leaves onto the electrostatic roller 5 as it passes over the tea leaves. Then, as the electrostatic roller 5 rotates, the impurities are blocked by the guide trough 6. Afterward, the motor 9 drives the lead screw 7 to rotate via the chain 10. The scraper 8 located on the lead screw 7 begins to move intermittently left and right, scraping the impurities into the guide trough 6. The impurities then slide into the collection hopper 11, while the tea leaves, after being cleaned by several electrostatic rollers 5, slide out from the end of the conveying trough 2 away from the hopper 3.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
