Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and in particular to a device for separating tea leaves from tea dust. Background Technology
[0002] Tea refers to the raw material for beverages made from the tender leaves and buds of the tea plant. There are many types of tea, which can be divided into six categories according to different processing methods and fermentation levels: green tea, black tea, oolong tea, yellow tea, white tea, and dark tea. In the tea processing process, sieving the tea leaves to separate tea dust is an important process. Tea dust refers to the small fragments produced during the processing, transportation, or storage of tea leaves. If these fragments are mixed into the finished tea, they will affect the appearance and taste of the tea and reduce the overall quality of the tea.
[0003] Existing technologies for separating tea leaves from tea dust mainly include methods such as vibrating sieving and air separation. Among these technologies, a common method is to use mechanical vibration to drive a screen to separate tea dust from the tea leaves. However, this vibrating sieving method has some problems. Especially when sieving tea leaves, vibrating sieving often causes physical damage to the tea leaves. In particular, under strong vibration, the tea leaves and buds are easily broken, affecting their appearance and quality. If the screen cylinder does not rotate, the separation efficiency will be greatly reduced, and it will be impossible to effectively separate tea dust from the tea leaves, especially when the particle size of the tea dust and tea leaves is similar. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a tea and tea dust separation device, which aims to improve the problem that the existing tea and tea dust separation devices cannot drive the sieve cylinder to rotate for sieving.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tea leaf and tea dust separation device, comprising a support frame, a processing box fixedly connected inside the support frame, a motor fixedly connected inside the support frame, a rotating shaft fixedly connected to the output end of the motor, a drive pulley fixedly connected to the right side of the rotating shaft, a driven pulley connected to the drive pulley via a belt, a rotating rod fixedly connected inside the driven pulley, a disc fixedly connected to the left side of the rotating rod, fixed seats fixedly connected to both sides of the left side of the disc, positioning rings fixedly connected to the left side of each of the two fixed seats, and a sieve cylinder provided on the opposite side of each of the two fixed seats.
[0006] Furthermore, each of the two fixed seats is fixedly connected to a fixed ring on one side, and each of the multiple fixed rings is threaded with a screw. Each of the multiple screws is threaded with a clamping plate at one end and a throttle handle is fixedly connected to one end of each of the multiple screws that are far apart from each other.
[0007] Furthermore, limiting blocks are fixedly connected to both outer sides of the screen cylinder, and both limiting blocks are slidably connected inside the fixed base.
[0008] Furthermore, limit rods are fixedly connected to all four sides of the left side of the positioning ring, and a handle is fixedly connected to the left side of the screen cylinder.
[0009] Furthermore, a limiting groove is provided on one side of the interior of the processing box, and multiple limiting rods are slidably connected inside the limiting groove.
[0010] Furthermore, a processing box is fixedly connected to the upper part of the processing box, and a feeding hopper is fixedly connected to the bottom of the processing box.
[0011] Furthermore, both sides of the processing box are rotatably connected to a box door, and the screen cylinder is rotatably connected inside the processing box.
[0012] Furthermore, the screen cylinder has a feed inlet inside, and screen cylinders are provided on opposite sides of the plurality of clamping plates.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the starting motor drives the rotating shaft, the driving pulley, the driven pulley, the rotating rod and the disc to rotate. The disc, through the positioning ring, causes the screen cylinder to rotate and screen inside the processing box. The tea dust remains in the screen cylinder, and the tea leaves are discharged through the hopper, thus achieving effective separation of tea leaves and tea dust and improving hygiene and safety.
[0015] 2. In this utility model, by rotating the handle, the screw is rotated, causing multiple clamping plates to move away from each other, thus releasing the fixation on the sieve cylinder. Pulling the handle moves the sieve cylinder, and the limiting block slides out of the fixing seat, allowing the sieve frame to be removed. This facilitates the disassembly, replacement, and cleaning of the sieve cylinder, maintaining its cleanliness and ensuring the quality of the tea. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a tea leaf and tea dust separation device, comprising a support frame 1, a processing box 23 fixedly connected inside the support frame 1, a motor 2 fixedly connected inside the support frame 1, a rotating shaft 3 fixedly connected to the output end of the motor 2, a driving pulley 4 fixedly connected to the right side of the rotating shaft 3, a driven pulley 6 connected to the driving pulley 4 via a belt 5, a rotating rod 7 fixedly connected inside the driven pulley 6, a disc 8 fixedly connected to the left side of the rotating rod 7, and fixed seats 12 fixedly connected to both sides of the left side of the disc 8. Each of the two fixed seats 12 is fixedly connected with a positioning ring 9. Each of the two fixed seats 12 is provided with a screen cylinder 13 on one side of the opposite side. Each of the four sides of the left side of the positioning ring 9 is fixedly connected with a limit rod 10. Each of the screen cylinder 13 is fixedly connected with a handle 19. Each of the two fixed seats 12 is provided with a limit groove 11 on one side of the inside of the processing box 23. Multiple limit rods 10 are slidably connected inside the limit groove 11. Each of the two fixed seats 23 is fixedly connected with a processing box 23 on the top. Each of the two fixed seats 23 is fixedly connected with a hopper 22 on the bottom. Each of the two external sides of the processing box 23 is rotatably connected with a box door 20. Each of the two fixed seats 12 is rotatably connected inside the processing box 23.
[0026] Tea leaves are fed into the sieve cylinder 13 through the feed hopper 21. The tea leaves undergo rotary sieving in the sieve cylinder 13, separating tea leaves from tea dust based on the size of the sieve holes. Then, the motor 2 is started, and its output drives the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 in turn drives the driving pulley 4 to operate. The driving pulley 4 is connected to the driven pulley 6 via a belt 5, enabling its rotation. The rotational power of the driven pulley 6 is transmitted to the rotating rod 7 and the disc 8, causing them to rotate as well. The rotation of the disc 8 drives the positioning ring 9, which is fixed between the two fixed seats 12, to rotate. Multiple limiting rods 10 slide within limiting grooves 11, which limit the movement trajectory of the limiting rods 10. Together with the limiting rods 10, they maintain the correct rotation path of the screen cylinder 13. Under the coordinated action of multiple limiting grooves 11, the fixed seat 12 guides the screen cylinder 13 to rotate within the processing box 23, completing the screening process. During this process, tea dust is trapped inside the screen cylinder 13, while the screened tea is smoothly discharged through the feed hopper 22. The box door 20 is used to open and close the processing box 23, making it easy for operators to access the screen cylinder 13 and other internal components.
[0027] Reference Figure 2 , Figure 5 and Figure 6 Each of the two fixed seats 12 has a fixed ring 15 fixedly connected to one side of each other. Each of the multiple fixed rings 15 has a screw 17 threadedly connected inside. Each of the multiple screws 17 has a clamping plate 18 threadedly connected to one end of each other. Each of the multiple screws 17 has a handle 16 fixedly connected to one end of each other. Each of the two outer sides of the screen cylinder 13 has a limit block 14 fixedly connected. Each of the two limit blocks 14 is slidably connected inside the fixed seat 12. The screen cylinder 13 has a feed port inside. Each of the multiple clamping plates 18 has a screen cylinder 13 on one side of each other.
[0028] After completing the tea sieving operation, the operator first opens the two chamber doors 20, and then rotates multiple handles 16. As the handles 16 rotate, the screw 17 rotates accordingly. This series of actions causes multiple clamping plates 18 to gradually separate, thereby releasing the fastening of the sieve cylinder 13. The function of the clamping plates 18 is to fix the sieve cylinder 13 during the sieving process and prevent it from moving. When it is necessary to disassemble the sieve cylinder 13, the clamping plates 18 separate to release the sieve cylinder 13. Then, the operator gently pulls the handle 19 to move the sieve cylinder 13 smoothly. During this process, the movement of the sieve cylinder 13 causes the two limiting blocks 14 to slide within the fixed seat 12 until they exit from the fixed seat 12, successfully completing the removal of the sieve cylinder 13. The limiting blocks 14 play a guiding and limiting role during the movement of the sieve cylinder 13, ensuring that the sieve cylinder 13 moves out of the processing chamber 23 smoothly and correctly. The fixed seat 12 is used to support and fix the sieve cylinder 13, and at the same time provides a sliding track for the limiting blocks 14.
[0029] Working principle: First, tea leaves are poured into the sieve cylinder 13 through the feed hopper 21. The motor 2 is started, and its output drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the drive pulley 4 to rotate, which in turn drives the driven pulley 6 via the belt 5. The driven pulley 6 then drives the rotating rod 7 and the disc 8 to rotate. The disc 8 drives the positioning ring 9, connected by two fixed seats 12, to rotate. As the positioning ring 9 rotates, it causes multiple limiting rods 10 to slide within the limiting grooves 11. With the cooperation of the multiple limiting grooves 11, the two fixed seats 12 drive the sieve cylinder 13 to rotate within the processing box 23 for sieving. Tea dust remains inside the sieve cylinder 13, while the tea leaves are discharged through the feed hopper 22, effectively separating the tea leaves and tea dust. Screening removes tea dust and impurities, ensuring the hygiene and safety of the tea. After screening, the operator opens the two doors 20 and rotates multiple handles 16. The rotation of handles 16 drives screws 17 to rotate, causing multiple clamping plates 18 to move away from each other, releasing the fixation on the sieve cylinder 13. Then, the operator pulls the handle 19, which moves the sieve cylinder 13. As the sieve cylinder 13 moves, it causes two limiting blocks 14 to slide inside the fixed seat 12, allowing the two limiting blocks 14 to move out of the fixed seat 12. This allows the sieve cylinder 13 to be easily disassembled, replaced, and cleaned, helping to maintain the cleanliness of the sieve cylinder 13 and ensuring the quality of the tea.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
