Description
Technical Field
[0001] This utility model relates to the technical field of flower tea production equipment, specifically a screening device for flower tea production. Background Technology
[0002] Scented tea, also known as fragrant tea, is a type of reprocessed tea unique to China, made by steeping the flowers, leaves, or fruits of plants. It utilizes tea's ability to absorb odors; fragrant fresh flowers are steeped with fresh tea leaves, allowing the tea to absorb the aroma. The dried flowers are then removed, resulting in a tea with a rich aroma and a deep color. Scented tea primarily uses green tea, black tea, or oolong tea as the base, combined with fragrant fresh flowers as raw materials, and is produced using a scenting process. During the production of scented tea, screening devices are frequently used to remove broken tea leaves and tea dust, preventing them from affecting the quality of the packaged product.
[0003] The existing patent document, authorized by CN222287920U, discloses a screening device for flower tea production, including a frame and a sieve plate. A bulk material bin is fixedly installed on the frame, and a rotating roller is rotatably installed inside the bulk material bin, with the roller located within the bulk material bin. This technical solution, by installing a bulk material bin on the top of the sieve plate to disperse the flower tea, prevents insufficient screening caused by some flower tea sticking together during the screening process. However, when flower tea splashes onto the inner wall of the feed hood due to vibration, the gathered flower tea cannot be dispersed, which also affects the integrity of the screening. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a screening device for flower tea production, which solves the problem that when flower tea splashes onto the inner wall of the feeding hood due to vibration, the flower tea cannot be dispersed and the integrity of the screening is also affected. During the operation of the screening device, when flower tea splashes onto the inner wall of the feeding hood due to vibration, the convex block uses elastic buffering collision force to disperse the gathered flower tea, allowing it to fall back into the screening frame to participate in screening, thus ensuring the integrity of the screening.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a screening device for flower tea production, comprising a vibrating screen assembly, a feeding assembly, and a guiding assembly. The vibrating screen assembly includes a bottom frame, a screening frame, and an upper frame. The feeding assembly includes a feeding hood. The guiding assembly includes a first retaining ring and a second retaining ring. One end of the upper frame is connected to a coarse material outlet. The inner wall of the screening frame is connected to a mesh frame and a ball-carrying tray. A ball-blocking ring is connected to the top of the ball-carrying tray. A striking rod is connected to the inner wall of the upper frame. A mounting top plate is connected to the lower end of the feeding hood. A connecting pipe is connected to the end of the feeding hood away from the mounting top plate. A feeding inlet is connected to the end of the connecting pipe away from the feeding hood. A guiding plate is connected to the inner wall of the first retaining ring. A guiding groove is formed on the inner side of the guiding plate. An mounting protrusion is connected to the inner wall of the feeding hood. A convex block is wrapped around the outer ring of the mounting protrusion.
[0006] The beneficial effects of this utility model are as follows: During the operation of the screening device, the flower tea splashes onto the inner wall of the feed hood due to vibration. The convex block uses elastic buffering collision force to disperse the gathered flower tea, causing it to fall back into the screening frame to participate in screening, thus ensuring the integrity of the screening.
[0007] In order to make the screening frame vibrate periodically and cause the flower tea on the frame to move in a directional, energetic manner:
[0008] As a further improvement to the above technical solution: the bottom frame is connected to the base cylinder by a shock-absorbing spring, and one end of the bottom frame is connected to a fine material outlet.
[0009] The beneficial effects of this improvement are as follows: when the vibrating motor of the vibrating screen assembly is started, the equipment enters the screening state. The composite inertial force generated by the eccentric blocks with different phases at the upper and lower ends drives the bottom frame, screening frame and upper frame to make a compound rotational motion. The screening frame drives the screen frame to make periodic vibration, and makes the tea on the screen frame make directional jumping motion. During this process, the material smaller than the screen frame aperture falls into the bottom frame through the screen holes of the screen frame, becomes the undersize material and is discharged from the fine material outlet. The material larger than the screen frame aperture is discharged from the coarse material outlet after continuous jumping motion.
[0010] To continuously agitate the sticky flower tea, ensuring it is evenly dispersed and sieved through a mesh frame:
[0011] As a further improvement to the above technical solution: the striking rod is installed in the middle of the inner wall of the upper frame by bolts at equal intervals around its circumference, and the screening frame is set between the bottom frame and the upper frame and is connected to both.
[0012] The beneficial effects of this improvement are: when the vibrating screen assembly is running, the striking rod vibrates with the upper frame, continuously striking the sticky flower tea, ensuring that it is evenly dispersed and screened through the screen frame.
[0013] In order for the bouncing balls to repeatedly bounce and impact the mesh frame, thereby shaking off the tea granules attached to the mesh frame and increasing the material's permeability:
[0014] As a further improvement to the above technical solution: a mounting plate is welded to the top of the upper frame, the two mounting plates are connected by screws, a sealing gasket is provided at the connection of the two mounting plates, and a bouncing ball is provided on the inner side of the ball-blocking ring.
[0015] The beneficial effects of this improvement are as follows: By installing the top plate and the screening frame, the upper frame and the feed hood are assembled and connected. When the vibrating screen assembly is working, the bouncing ball continuously collides and rolls with the screen frame. In the production of flower tea, some irregularly shaped and fuzzy flower tea may get stuck between the screen holes. The movement of the bouncing ball can prevent the material in the screen holes from accumulating and clogging, keeping the screen frame unobstructed and improving screening efficiency. The bouncing ball, through repeated bouncing and impacting the screen frame, can shake off the flower tea particles attached to the screen frame, increase the material's permeability, and allow flower tea particles of different sizes to pass through the corresponding screen holes more accurately, achieving better grading and screening.
[0016] To guide the flower tea as it falls into the feed inlet, a funnel structure is used:
[0017] As a further improvement to the above technical solution: the top of the feed inlet is rotatably connected to a dust cover via a rotating hinge; the feed inlet has a funnel-shaped structure; and the ball-blocking ring is positioned between the ball-carrying disc and the net frame.
[0018] The beneficial effects of this improvement are as follows: by setting up the connecting pipe, the inlet and the inlet cover can be connected. Before adding the flower tea, open the dust cover, pour the flower tea into the inlet, and use the funnel structure to guide the flower tea to fall.
[0019] To achieve uniform material distribution through two-stage flow guidance and prevent tea flower accumulation:
[0020] As a further improvement to the above technical solution: the first retaining ring is located directly above the second retaining ring, the second retaining ring is fixed to the inner wall of the feed inlet by a positioning plate, and the inner diameter of the guide plate gradually decreases from top to bottom.
[0021] The beneficial effects of this improvement are as follows: When in use, the dust cover is opened, and the flower tea falls into the guide plate of the first retaining ring through the feed port, and slides down to the second retaining ring along the guide groove. The two-stage flow guide achieves uniform distribution and avoids the accumulation of flower tea.
[0022] To allow the herbal tea to slide on the guide plate and be centrally conveyed downwards through the guide chute:
[0023] As a further improvement to the above technical solution: the guide plate on the inner wall of the second retaining ring is connected to the inner wall of the feed inlet through a gradually narrowing inner diameter structure and a guide groove, and the circumferential surface of the second retaining ring is connected to the inner wall of the feed inlet through a positioning plate.
[0024] The beneficial effects of this improvement are as follows: after the flower tea is guided by the first retaining ring, it falls onto the guide plate of the inner ring of the second retaining ring. The flower tea slides on the guide plate and is conveyed downward in a concentrated manner through the guide groove. At the same time, the guide plate of the second retaining ring, through its inner diameter tapering structure, blocks and guides the splashed flower tea, preventing it from overflowing the device.
[0025] To allow the convex blocks to utilize elasticity to cushion collision forces, break up the clustered flower tea and allow it to fall back into the screening box for further sieving:
[0026] As a further improvement to the above technical solution: the convex block is a hemispherical hollow rubber structure, and the convex block is fixed to the inner wall of the feed hood by wrapping and installing protrusions.
[0027] The beneficial effects of this improvement are as follows: During the operation of the screening device, the flower tea splashes onto the inner wall of the feed hood due to vibration. The convex block uses elastic buffering to break up the gathered flower tea and make it fall back into the screening frame to participate in screening, thus ensuring the integrity of the screening.

[0039] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0040] like Figure 1-8As shown, a screening device for flower tea production includes a vibrating screen assembly 1, a feeding assembly 2, and a guiding assembly 3. The vibrating screen assembly 1 includes a bottom frame 12, a screening frame 15, and an upper frame 16. The feeding assembly 2 includes a feeding hood 21. The guiding assembly 3 includes a first retaining ring 31 and a second retaining ring 35. One end of the upper frame 16 is connected to a coarse material outlet 14. The inner wall of the screening frame 15 is connected to a mesh frame 151 and a ball-carrying tray 152. The top of the ball-carrying tray 152 is connected to a ball-blocking ring 153. The inner wall of the upper frame 16 is connected to a striking rod 161. The feeding hood... The lower end of the feed hood 21 is connected to a mounting top plate 22. A connecting pipe 24 is connected to the end of the feed hood 21 away from the mounting top plate 22. A feed inlet 25 is connected to the end of the connecting pipe 24 away from the feed hood 21. A guide plate 32 is connected to the inner wall of the first retaining ring 31. A guide groove 33 is formed on the inner side of the guide plate 32. A mounting protrusion 37 is connected to the inner wall of the feed hood 21. A convex block 36 surrounds the outer ring of the mounting protrusion 37. The bottom frame 12 is connected to the base cylinder 11 via a shock-absorbing spring. A fine material outlet 13 is connected to one end of the bottom frame 12. Start When the vibrating motor of vibrating screen assembly 1 enters the screening state, it generates a compound inertial force through eccentric blocks of different phases at the upper and lower ends, driving the bottom frame 12, screening frame 15, and upper frame 16 to perform a compound rotational motion. The screening frame 15 drives the screen frame 151 to vibrate periodically, and causes the tea leaves on the screen frame 151 to perform a directional jumping motion. During this process, materials smaller than the aperture of the screen frame 151 fall into the bottom frame 12 through the screen holes of the screen frame 151, becoming undersize material and being discharged from the fine material outlet 13. Materials larger than the aperture of the screen frame 151 are discharged from the coarse material outlet 14 after continuous jumping motion. The knocking... The striking rod 161 is installed in the middle of the inner wall of the upper frame 16 by bolts at equal intervals around its circumference. The screening frame 15 is set between the bottom frame 12 and the upper frame 16 and is connected to both. When the vibrating screen assembly 1 is running, the striking rod 161 vibrates with the upper frame 16 and continuously strikes the sticky flower tea to ensure that it is evenly dispersed and screened through the screen frame 151. The top of the upper frame 16 is welded with a mounting plate 22. The two mounting plates 22 are connected by screws 23. A sealing gasket is provided at the connection between the two mounting plates 22. A bouncing ball 154 is provided on the inner side of the ball-blocking ring 153.The top plate 22 and the screening frame 15 are used to assemble and connect the upper frame 16 and the feed hood 21. During the operation of the vibrating screen assembly 1, the bouncing ball 154 continuously collides and rolls with the screen frame 151. In the production of flower tea, some irregularly shaped or fuzzy flower tea may get stuck between the screen holes. The movement of the bouncing ball 154 prevents material from accumulating and clogging in the screen holes, keeping the screen frame 151 unobstructed and improving screening efficiency. The bouncing ball 154, through its cyclical bouncing and impacting of the screen frame 151, can shake off flower tea particles attached to the screen frame 151, increasing the material's permeability. To allow tea granules of different sizes to pass more precisely through the corresponding sieve holes and achieve better grading and screening, a dust cover 26 is rotatably connected to the top of the feed inlet 25 via a rotating hinge. The feed inlet 25 has a funnel-shaped structure, and the ball-blocking ring 153 is positioned between the ball-carrying disc 152 and the mesh frame 151. The feed inlet 25 is connected to the feed hood 21 via a connecting pipe 24. Before adding tea, the dust cover 26 is opened, and the tea is poured into the feed inlet 25. The funnel structure guides the tea as it falls. The first retaining ring 31 is located directly above the second retaining ring 35, which is fixed... Position plate 34 is fixed to the inner wall of feed inlet 25. The inner diameter of guide plate 32 gradually decreases from top to bottom. In use, dust cover 26 is opened, and flower tea falls through feed inlet 25 into guide plate 32 of first retaining ring 31, slides down guide groove 33 to second retaining ring 35, and achieves uniform distribution through two-stage flow guidance to avoid flower tea accumulation. Guide plate 32 on inner wall of second retaining ring 35 has a gradually narrowing inner diameter structure and guide groove 33. The circumference of second retaining ring 35 is connected to inner wall of feed inlet 25 through positioning plate 34. After being guided by first retaining ring 31, flower tea falls into guide plate 32 on inner ring of second retaining ring 35. Above, the flower tea slides on the guide plate 32 and is conveyed downwards in a concentrated manner through the guide trough 33. Simultaneously, the guide plate 32 of the second retaining ring 35, with its gradually narrowing inner diameter structure, blocks and guides splashed flower tea, preventing it from overflowing the device. The convex block 36 is a hemispherical hollow rubber structure, and it is fixed to the inner wall of the feed hood 21 by wrapping and installing the convex block 37. During the operation of the screening device, flower tea splashes onto the inner wall of the feed hood 21 due to vibration. The convex block 36 uses its elasticity to buffer the impact force, breaking up the accumulated flower tea and causing it to fall back into the screening frame 15 to participate in the screening, ensuring the integrity of the screening.
[0041] The working principle of this utility model is as follows: In use, the dust cover 26 is opened, and the flower tea falls through the inlet 25 into the guide plate 32 of the first retaining ring 31. It then slides along the guide groove 33 to the second retaining ring 35. The two-stage flow guidance achieves uniform distribution, preventing flower tea accumulation. After being guided by the first retaining ring 31, the flower tea falls onto the guide plate 32 on the inner ring of the second retaining ring 35. The flower tea slides on the guide plate 32 and is centrally conveyed downwards through the guide groove 33. Simultaneously, the guide plate 32 of the second retaining ring 35, with its gradually narrowing inner diameter structure, blocks and guides splashed flower tea, preventing it from overflowing the screening device. During operation, the flower tea splashes onto the inner wall of the feed hood 21 due to vibration. The convex block 36 uses its elasticity to buffer the impact force, breaking up the accumulated flower tea and causing it to fall back into the screening frame 15 for screening, ensuring the integrity of the screening. The feed inlet 25 is connected to the feed hood 21 through the connecting pipe 24. Before adding flower tea, the dust cover 26 is opened, and the vibration motor of the vibrating screen assembly 1 is started. The equipment enters the screening state. The eccentric blocks at the upper and lower ends generate a compound inertial force, driving the bottom frame 12, the screening frame 15, and the upper frame 16 to perform a compound rotational motion. The screening frame 15 drives the screen frame 151. The vibrating screen assembly 11 vibrates periodically, causing the tea leaves on the screen frame 151 to move in a directional, bouncy motion. The top plate 22 and the screening frame 15 are used to assemble and connect the upper frame 16 and the feed hood 21. During operation, the bouncing balls 154 continuously collide with and roll against the screen frame 151. In tea production, some irregularly shaped or fuzzy tea leaves may get stuck in the screen holes. The movement of the bouncing balls 154 prevents material from accumulating and clogging in the screen holes, keeping the screen frame 151 unobstructed and improving screening efficiency. The bouncing balls 154 repeatedly bounce and impact the screen frame 151. The vibrating screen assembly 1 can shake off the tea particles attached to the screen frame 151, increase the material's permeability, and allow tea particles of different sizes to pass through the corresponding sieve holes more accurately, achieving better grading and screening. When the vibrating screen assembly 1 is running, the striking rod 161 vibrates with the upper frame 16, continuously striking the sticky tea particles to ensure that they are evenly dispersed and screened through the screen frame 151. During this process, materials smaller than the aperture of the screen frame 151 fall into the bottom frame 12 through the screen holes of the screen frame 151, becoming undersize material and being discharged from the fine material outlet 13. Materials larger than the aperture of the screen frame 151 are discharged from the coarse material outlet 14 after continuous jumping motion.
