[0001] The invention belongs to the technical field of tea impurity removal, and in particular relates to an electrostatic impurity removal device for tea processing. Background Art

[0002] Tea refers to the leaves and buds of the Camellia sinensis plant. Tea contains catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which can improve human health and are known as "one of the world's three major beverages." Tea is produced through a series of steps, including spreading, withering, straightening, shaping, lifting, drying, and selecting. Before production, tea leaves must be cleaned to ensure their cleanliness and hygiene. Electrostatic adsorption is typically used to remove impurities such as hair, chicken feathers, fibers, fuzz, and ash.

When the operator lifts it by the handle, the snap-on strip is precisely engaged with the snap-on grooves of the side panels 1 and 2 to ensure that no impurities are spilled during replacement, and a single replacement takes less time.

One end of the electrostatic roller 403 extends through the rear side of the second side plate 402 and is fixedly sleeved with a gear 1 404. A collection assembly 5 is provided on one side of the electrostatic roller 403. The collection assembly 5 includes a guide block 501. The two ends of the guide block 501 are fixedly connected to the side plates 1 401 and 2 402, respectively. A collection frame 502 is provided on one side of the bottom of the guide block 501. In the present invention, the operator pours tea leaves onto the top of one end of the conveyor belt 105, and the rotating motor 104 drives the active roller 102 and the driven roller 103 to rotate synchronously to stably convey the tea leaves. During this process, the rotating motor 202 drives the dispersion roller 203 to rotate. The teeth on its surface can disperse the accumulated tea leaves and spread them evenly, so that the thickness of the tea leaves is spread out and the electrostatic adsorption blind spots caused by accumulation are avoided. The lateral reciprocating movement of the guide ring 306 links the guide ring 306 with the connecting piece 1 307, the connecting piece 2 308 and the bracket 2 301, and pushes the dispersion roller 203 to swing horizontally, forming a compound motion of rotation and swinging, which can completely break up the clumped tea leaves, improve the dispersion efficiency, and provide a uniform material foundation for subsequent electrostatic impurity removal.

[0032] The conveying assembly 1 includes a support plate 101, and there are two support plates 101. The two support plates 101 are respectively connected to an active roller 102 and a driven roller 103 that rotate with each other.

The output end of the rotating motor 104 is fixedly connected to the active roller 102 through a coupling. The surfaces of the master and slave rollers and the driven roller 103 are connected to each other with a conveyor belt 105. The support plate 101 cooperates with the active roller 102 and the driven roller 103 to achieve support. The operation of the rotating motor 104 will drive the active roller 102 to rotate, and the setting of the conveyor belt 105 will drive the driven roller 103 to rotate, and realize the transfer of tea leaves on the surface of the conveyor belt 105.

[0033] The bracket 1 201 and the support plate 101 are fixedly connected to each other. A rotating motor 202 is fixedly installed on one side of the bracket 1 201. The output end of the rotating motor 202 is fixedly connected to the dispersion roller 203 through a coupling. The operation of the rotating motor 202 will drive the dispersion roller 203 to rotate, thereby realizing the dispersion treatment of the tea leaves by the dispersion roller 203.

[0034] The second bracket 301 and the support plate 101 are fixedly connected to each other. A rotating motor 302 is fixedly installed on the top of the second bracket 301.

One end of the shaft 303 passes through the bottom of the second bracket 301 and is fixedly connected to the disc 304. The operation of the rotating motor 302 will drive the shaft 303 and the disc 304 to rotate.

[0035] A guide block 305 is fixedly mounted on the bottom of the disc 304. The guide block 305 is slidably connected to a guide ring 306. A first connector 307 is fixedly mounted on both sides of the guide ring 306. A second connector 308 is fixedly mounted between the first connectors 307. The second connector 308 is fixedly connected to the second bracket 301. The rotation of the disc 304 drives the guide block 305 to move around the shaft 303. This also causes the guide ring 306 to reciprocate laterally. The guide ring 306 drives the first connector 307, the second connector 308, and the second bracket 301 to move synchronously.

[0036] A guide block 309 is fixedly installed at the bottom of the connecting piece 307, and the two guide blocks 309 are internally connected to each other in a sliding manner with guide rods 3010. Both ends of the guide rods 3010 are fixedly installed with fixed plates 3011 fixedly connected to the bracket 201. The fixed plates 3011 support and fix the guide rods 3010, and the sliding connection between the guide rods 3010 and the guide blocks 309 will guide the movement of the connecting piece 307.

[0037] The side plate 1 401 and the side plate 2 402 are fixedly connected to the top of the support plate 101. There are three electrostatic rollers 403. A gear 2 405 is meshed between two adjacent gears 1 404. A rotating rod 406 is fixedly sleeved inside the gear 2 405 and is rotatably connected to the side plate 2 402 through a bearing. A rotating motor 407 is fixedly installed on one side of the side plate 2 402. One end of the electrostatic roller 403 located at one end of the side plate 2 402 is fixedly sleeved with the output end of the rotating motor 407. Plate one 401 and side plate two 402 both provide support and smooth rotation for the electrostatic roller 403. During the operation of rotating motor four 407, the electrostatic roller 403 and gear one 404 at its output end are preferentially driven to rotate. Through the meshing characteristics of the gears, gear two 405 will transmit the rotation to the other two electrostatic rollers 403 in turn, and under the action of gear one 404, the rotation directions of the three electrostatic rollers 403 will be the same. To cooperate with the use of the collection frame 502, the electrostatic roller 403 rotates clockwise.

[0038] Both sides of the collection frame 502 are fixedly installed with snap-in strips 503, and the interior of the side panel 1 401 and the side panel 2 402 are provided with snap-in grooves 504 for cooperating with the snap-in strips 503. One end of the collection frame 502 passes through one side of the side panel 1 401 and is fixedly installed with a handle 505. The snap-in strip 503 and the snap-in groove 504 are snapped into each other, which will realize the insertion and positioning of the collection frame 502 with the side panel 1 401 and the side panel 2 402 respectively, and the handle 505 facilitates the operator to pull the collection frame 502.

[0039] Brief description of the usage process: The operator pours the tea leaves onto the top of one end of the conveyor belt 105, and rotates the motor 104 to drive the active roller 102 and the driven roller 103 to rotate synchronously to stably convey the tea leaves. During this process, the motor 202 is rotated to drive the dispersion roller 203 to rotate. The teeth on its surface can disperse and evenly spread the accumulated tea leaves, so that the thickness of the tea leaves is spread out, avoiding the electrostatic adsorption blind spots caused by accumulation. Then, the motor 302 is rotated to drive the shaft 303 and the disc 304 to rotate, causing the guide block 305 to perform a circular motion around the shaft 303, driving the guide ring 306 to produce a lateral reciprocating movement. The guide ring 306 is linked to the connector 1 307, the connector 2 308 and the bracket 2 301, pushing the dispersion roller 203 to swing horizontally, forming a compound motion of rotation and swinging, which can completely break up the clumped tea leaves, improve the dispersion efficiency, and provide a uniform material foundation for subsequent electrostatic impurity removal. The dispersed tea leaves pass at a constant speed beneath three electrostatic rollers 403. Rotating motor 407 drives electrostatic rollers 403 and gear 1 404 to rotate synchronously. The gears mesh, ensuring that all three rollers rotate clockwise in the same direction, forming a continuous electrostatic adsorption surface. The surface of electrostatic rollers 403 is made of conductive rubber and negatively charged by a built-in high-voltage power supply. This is prior art and will not be described in detail here. This allows the adsorption of positively charged impurities from the tea leaves, such as insect debris and grass clippings. As electrostatic rollers 403 rotate to guide block 501, the contact gap between guide block 501 and electrostatic rollers 403 allows impurities on the surface of electrostatic rollers 403 to be removed. These impurities fall along the inclined surface of guide block 501 into collection frame 502, achieving high collection efficiency. Collection frame 502 utilizes a drawer-like design. When the operator lifts it using handle 505, the snap-on strips 503 precisely engage with the snap-on slots 504 of side panels 1 401 and 2 402, ensuring that no impurities are spilled during replacement, minimizing the time required for a single replacement.
