Abstract
Description
Technical Field
[0001] This utility model relates to the field of substitute tea processing technology, and in particular to a substitute tea grading and selection device. Background Technology
[0002] Substitute teas, as a type of tea beverage made from the roots, stems, leaves, or flowers of plants and consumed through steeping or boiling, are prepared and enjoyed in the same way as traditional teas. Due to the diverse range of raw materials used, these tea beverages often require mechanical packaging equipment to ensure standardized and uniform packaging during processing. In this process, precise grading and selection of substitute teas are crucial, as they directly affect the quality and taste of the finished tea.
[0003] However, existing substitute tea grading and selection devices have certain limitations in design and function, especially in their lack of sufficient consideration for the differences in the characteristics of different tea raw materials. Specifically, these devices often use a fixed vibration frequency in the vibration selection process, making it difficult to flexibly adjust the frequency according to the different substitute tea raw materials, such as density, moisture, and shape. This "one-size-fits-all" approach not only affects the screening efficiency but may also lead to inaccurate tea grading, thus affecting the final tea beverage quality. Therefore, it is necessary to design a substitute tea grading and selection device with adjustable vibration frequency. Utility Model Content

The two ends of the arc plate are connected to the bottom of the adjacent moving rods. A servo motor is provided at the center of the top of the moving plate. The output shaft of the servo motor is connected to the top of the lead screw through a coupling.
[0007] More preferably, the drive assembly includes a mounting frame, a rotary motor, and a cam. Mounting frames are provided at both the front and rear of the hopper in the middle. A rotary motor is mounted on the mounting frame, and a cam is mounted on the output shaft of the rotary motor. The cam is connected to the first top block.
[0008] More preferably, it also includes a rotating shaft, a baffle, a second top block, a torsion spring, a guide rod, a movable frame, a third top block, and an electric push rod. The lower part of the funnel is symmetrically arranged with rotating shafts, each with a baffle. The front and rear ends of the two rotating shafts are each equipped with a second top block, and a torsion spring is sleeved on the rotating shaft. The front and rear side walls of the funnel are vertically arranged with guide rods, and a movable frame is slidably arranged between the two guide rods.

Detailed Implementation
[0020] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.
[0021] Example 1: A substitute tea grading and selection device, such as Figures 1-3As shown, the assembly includes a base 1, a bracket 2, a hopper 4, mounting rings 3, slide rails 5, a cover 6, a guide rod 7, a screen 8, an adjusting assembly 9, a driving assembly 10, and a funnel 11. The base 1 has brackets 2 symmetrically arranged on its top left and right sides via bolts. Mounting rings 3 are vertically spaced between the two brackets 2. Hoppers 4 are bolted together between the mounting rings 3 at the same horizontal position. The hoppers 4 are interconnected. A through hole is opened in the middle of the outer wall of each hopper 4. Slide rails 5 are symmetrically arranged on the outer wall of each hopper 4 around the through hole. A cover 6 is slidably mounted between two slide rails 5. Each guide rod 7 is slidably mounted on one of the three hoppers 4. The three guide rods 7 are eccentrically circumferentially arranged around the central axis of the hopper 4. A screen 8 is installed on the inner side of each of the three guide rods 7. An adjusting assembly 9 for adjusting the amplitude of the screen 8 is installed on the middle hopper 4. The adjusting assembly 9 includes a connecting frame 91, a guide sleeve 92, a moving rod 93, a crossbar 94, a first top block 95, a moving plate 96, a lead screw 97, an arc plate 98, and a servo motor 99. A connecting frame 91 is located between the middle of two adjacent guide rods 7. Guide sleeves 92 are vertically mounted at both ends of the connecting frame 91. The system includes two sliding rods 93, with a crossbar 94 positioned between their tops. A first top block 95 is located at the center of the bottom of the crossbar 94. A sliding plate 96 is positioned between the middle of the two sliding rods 93 on the left and between the middle of the two sliding rods 93 on the right. Each sliding plate 96 has a vertically rotating lead screw 97 in its center. A nut is embedded in the center of an arc-shaped plate 98, and the nut engages with the lead screw 97. Both ends of the arc-shaped plate 98 are connected to the bottom of the adjacent sliding rods 93. A servo motor 99 is located at the center of the top of the sliding plate 96. The output shaft is connected to the top of the lead screw 97 via a coupling. The hopper 4 in the middle is equipped with drive components 10 at both the front and rear to drive the adjustment component 9 to shake the screen 8. The drive component 10 includes a mounting frame 101, a rotary motor 102 and a cam 103. The hopper 4 in the middle is equipped with a mounting frame 101 at both the front and rear. The rotary motor 102 is mounted on the mounting frame 101. The output shaft of the rotary motor 102 is equipped with a cam 103. The cam 103 is connected to the first top block 95. A funnel 11 is provided between the tops of the bracket 2. The funnel 11 is located above the uppermost hopper 4.
[0022] When selecting materials for the substitute tea, staff adjust the vibration frequency of the screen 8 according to the characteristics of different substitute teas. By starting the servo motor 99 to rotate forward or reverse, the servo motor 99 drives the lead screw 97 to rotate forward or reverse, and the lead screw 97 drives the nut to move up or down. In turn, the arc plate 98 drives the moving rod 93 to move up or down. The moving rod 93 drives the first top block 95 to move up or down through the crossbar 94, thereby adjusting the distance between the first top block 95 and the cam 103. Then, the rotary motor 102 is started to drive the cam 103 to rotate. The rotating cam 103's protruding end presses the first top block 95 to move upward, thereby causing the entire adjusting assembly 9 to move the guide rod 7 upward. When the cam 103 stops pressing, the guide rod 7 and the adjusting assembly 9 return to their original positions under the action of gravity. The movement of the guide rod 7 drives the three screens 8 to rotate synchronously. Substitute teas of different sizes are sieved by the screens 8, and the substitute teas smaller than the sieve holes fall onto the lower screen 8. After screening, the lid 6 can be opened to collect the sorted substitute tea on the corresponding sieve 8. This device has a simple structure and is easy to adjust.
[0023] Example 2: Based on Example 1, such as Figure 4 and Figure 6 As shown, it also includes a rotating shaft 12, a baffle 13, a second top block 14, a torsion spring 15, a guide rod 16, a movable frame 17, a third top block 18, and an electric push rod 19. The lower part of the funnel 11 is symmetrically arranged with rotating shafts 12, each with a baffle 13. The front and rear ends of the two rotating shafts 12 are each equipped with a second top block 14. A torsion spring 15 is sleeved on the rotating shaft 12. The front and rear side walls of the funnel 11 are vertically equipped with guide rods 16. A movable frame 17 is slidably arranged between the two guide rods 16. The movable frame 17 is a rectangular frame that fits onto the funnel 11. The bottom front and rear of the movable frame 17 are each equipped with a third top block 18. The third top block 18 contacts and engages with the adjacent second top block 14. Electric push rods 19 are installed on the front and rear side walls of the movable frame 17. The push rod of the electric push rod 19 is connected to the movable frame 17.
[0024] like Figure 5 As shown, it also includes a sliding plate 20, a magnet 21 and a handle 22. An inverted V-shaped hole is opened on the front side wall of the funnel 11. The sliding plate 20 is slidably installed in the inverted V-shaped hole on the front side wall of the funnel 11. The sliding plate 20 is inverted V-shaped. A magnet 21 is installed on the top of the sliding plate 20. A handle 22 is installed on the front side of the sliding plate 20 by means of bolt connection.
[0025] like Figure 1 As shown, it also includes a protective shell 23. The protective shell 23 is provided on the top rear side of the base 1 to shield the adjustment component 9 and the drive component 10.
[0026] By activating the electric push rod 19, the electric push rod 19 drives the moving frame 17 to move downward. The third top block 18 of the moving frame 17 presses against the second top block 14. The second top block 14 drives the rotating shaft 12 to drive the baffle 13. The two baffles 13 rotate, and the substitute tea falls through the gap onto the sliding plate 20 on the lower side. The magnet 21 on the sliding plate 20 can attract some iron filings, which plays a filtering role. When an appropriate amount of substitute tea falls onto the screen 8, the operator activates the electric push rod 19 to reset. The torsion spring 15 drives the rotating shaft 12 and the baffle 13 to reset. The second top block 14 drives the third top block 18 and the moving frame 17 to reset. This device has a simple structure, can realize batch feeding, and can clean up iron filings.
