Description

Technical Field

[0001] The present invention belongs to the technical field of tea processing, and particularly relates to a double-layer tea shaking sieve machine. Background Art

[0002] Rolling is one of the core processes in tea processing (especially for green tea, black tea, oolong tea, etc.). By mechanically squeezing the tea leaves, the cell walls of the leaf mesophyll are broken, releasing tea juice (containing tea polyphenols, amino acids, aromatic substances, etc.), providing a basis for subsequent fermentation (such as black tea) or heat fixation (such as green tea); rolling makes the tea leaves curl into strip shapes (such as the "dragonfly head" of oolong tea and the "tight and thin strips" of black tea), improving the aesthetics and commercial value of the tea.

[0003] The rolled tea leaves need to be screened to remove tea stalks and fine powder in the tea leaves, improving the quality of the tea. In the field of tea processing, if the tea balls formed after the rolling process are directly subjected to vibrating screening, although vibrating screening itself has a certain dispersing function, for tea balls with relatively high viscosity and humidity, especially tea types such as oolong tea and black tea that have been heavily rolled, it is difficult to achieve complete dispersion of the tea balls only by vibrating screening.

[0004] There are limitations in the acceleration of vibrating screening. It mainly relies on the collision of the tea leaves' own weight with the sieve mesh to achieve dispersion, and the shear force on the tightly packed tea balls is significantly insufficient. This may cause the unsieved tea balls to block the upper sieve holes, especially the large-aperture sieve meshes, thereby reducing the effective screening area. Some tea leaves cannot be accurately graded according to particle size due to agglomeration, affecting the effect and efficiency of tea grading.

[0005] Based on this, the present invention designs a double-layer tea shaking sieve machine to solve the above problems. Summary of the Invention

The first magnetic block and the second magnetic block drive the guide plate to reset. The guide plate is arranged in an arc shape.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, a second drive assembly, a first gear, a second gear, a third gear, a first rotating cylinder, a second rotating cylinder, and a plug rod are adopted. The second drive assembly precisely controls the rotation of the first gear, the second gear, and the third gear. Since the first gear and the third gear are set to different sizes and are driven by the second gear, a transmission ratio with the rotational speed of the first gear being greater than that of the third gear is achieved. This design enables the plug rod on the surface of the second rotating cylinder to smoothly insert into the tea mass and push it to move to the right when the tea mass passes through the second rotating cylinder. When the plug rod on the surface of the first rotating cylinder inserts into the tea mass, due to the speed of the plug rod on the surface of the first rotating cylinder being greater than that of the plug rod on the surface of the second rotating cylinder, the speed difference generated between the two will have a strong tearing effect on the tea mass, effectively separating the tea mass. Combined with the vibration of the rotating filter frame itself, the dispersion effect of the tea mass is further enhanced. This composite action mechanism not only overcomes the defect of insufficient shear force of traditional vibration screening for tight tea masses but also avoids the problem of reduced screening area caused by tea mass blocking the sieve holes, ensuring that the tea can be accurately graded according to the particle size, thereby significantly improving the screening efficiency and effect of the tea mass.

[0018] 2. In the present invention, a second extrusion wheel, a bracket, a second spring, and a vibrating rod are adopted. During the rotation of the second gear, it will drive the second extrusion wheel to rotate synchronously. The second extrusion wheel controls the contact plate, the bracket, and the vibrating rod to move upward. When the protruding part of the second extrusion wheel separates from the contact plate, the elastic force of the second spring on the bracket will quickly control the vibrating rod to act downward on the first connecting shaft and the second connecting shaft. This vibrating action will be transmitted to the surface of the plug rod inserted into the tea mass, thereby reducing the internal friction of the tea mass. The tearing and separating effect of the tea mass is significantly improved, and the tea mass can be more thoroughly dispersed into smaller lumps. Since the vibrating action reduces the internal friction of the tea mass, it also effectively reduces the probability of the tea being broken during the tearing process, thus better maintaining the integrity of the tea. Through the ingenious structural design and the coordinated action of components in the present invention, the efficient and gentle dispersion of the tea mass is achieved, not only improving the screening efficiency and effect but also effectively protecting the quality of the tea.

[0019] 3. In the present invention, a pushing wheel, a moving rod, a knocking rod, an elastic telescopic rod, a guide plate, a first magnet, and a second magnet are adopted. During the rotation of the pushing wheel, it will push the moving rod forward. At this time, the knocking rod and the guide plate are in a separated state. After the convex part of the pushing wheel separates from the moving rod, the elastic telescopic rod quickly controls the knocking rod to reset by using its own elastic force, and the knocking rod forcefully knocks on the surface of the guide plate. This knocking force causes the guide plate to swing backward quickly, thereby pushing the tea leaves backward to impact on the surface of the rear guide plate. During this process, while the tea leaves are being quickly shaken, they are also subjected to the impact force, thus realizing the further dispersion of the tea leaf clusters. This dispersion method combining pushing and impact not only significantly improves the dispersion efficiency and effect of the tea leaf clusters, but also, since the impact force directly acts on the tea leaf clusters, avoids the excessive friction and extrusion that may exist in the traditional dispersion method, thereby effectively reducing the damage probability of the tea leaves during the dispersion process and better maintaining the integrity and quality of the tea leaves.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to the attached Figure 1 - attached Figure 10, the present invention provides a technical solution: a double-layer tea shaking sieve machine, including a side frame 1 and two rotating filter frames 3. The rotating filter frames 3 are arranged inside the side frame 1. A bottom frame 4 is fixedly connected to the lower part of the side frame 1. A first driving component 6 is fixedly connected to the side surface of the side frame 1. The output shaft of the first driving component 6 is fixedly connected to a gearbox 7 arranged outside the side frame 1. The output shaft of the gearbox 7 is connected to a transmission wheel group 8. Two rotating rods 9 are fixedly connected to the side surface of the transmission wheel group 8. The rotating rods 9 penetrate and rotate through the side surface of the side frame 1. One end of the rotating rod 9 located inside the side frame 1 is fixedly connected to a first extrusion wheel 10. The first extrusion wheel 10 is arranged under the rotating filter frame 3. A fixed frame 14 is fixedly connected to the front surface of the upper rotating filter frame 3. A differential control mechanism 15 is fixedly connected to the fixed frame 14. A rotating block releasing mechanism 16 arranged on the back surface of the rotating filter frame 3 is fixedly connected to the back surface of the differential control mechanism 15. A vibration mechanism 17 is arranged outside the differential control mechanism 15. An extrusion contact mechanism 18 is arranged outside the rotating block releasing mechanism 16. A guiding and spreading mechanism 19 installed inside the rotating filter frame 3 is arranged on the side surface of the extrusion contact mechanism 18.

[0024] The rotating filter frame 3 can rotate up and down inside the side frame 1 through a rotating shaft 2. The first driving component 6 controls the rotation of the two rotating rods 9 and the first extrusion wheel 10 through the gearbox 7 and the transmission wheel group 8. When the first extrusion wheel 10 rotates, an upward thrust is applied to the rotating filter frame 3. The first spring 12 applies a downward elastic force to the rotating filter frame 3. The two cooperate to achieve a vibration effect on the rotating filter frame 3.

[0025] Specifically, as Figures 1-3 shown, a rotating shaft 2 is rotatably connected between the rotating filter frame 3 and the side frame 1. A collection box 5 is fixedly connected to the lower part of the side frame 1. The collection box 5 is arranged inside the bottom frame 4. The rotating filter frame 3 is arranged in an inclined shape. A feeding hopper 13 is fixedly connected to the side frame 1. The outlet position of the feeding hopper 13 corresponds to the position of the upper rotating filter frame 3. A first spring 12 is fixedly connected to the rotating filter frame 3. The top end of the first spring 12 is fixedly connected to a cross plate 11 arranged on the inner wall of the side frame 1.

[0026] The first spring 12 applies a downward elastic force to the rotating filter frame 3, which is convenient for controlling the reset of the rotating filter frame 3.

[0027] Specifically, as Figures 4-5 and Figure 7 shown, the differential control mechanism 15 includes a second driving component 1501. An extension rod 1502 installed outside the fixed frame 14 is fixedly connected to the lower part of the second driving component 1501. The output shaft of the second driving component 1501 is fixedly connected to a first gear 1505. A second gear 1506 is meshed with the side surface of the first gear 1505. A third gear 1507 is meshed with the side surface of the second gear 1506. A first connecting shaft 1503 is fixedly connected to the back surface of the first gear 1505. A first bearing 1504 is sleeved outside the first connecting shaft 1503.

[0028] The back of the third gear 1507 is fixedly connected to a second connecting shaft 1508. A second bearing 1509 is sleeved outside the second connecting shaft 1508. Both the first bearing 1504 and the second bearing 1509 are fixedly connected to the fixing frame 14. Both the first connecting shaft 1503 and the second connecting shaft 1508 are connected outside the rotary deblocking mechanism 16. The back of the second gear 1506 is fixedly connected to a support shaft 1510. A support seat 1511 provided on the fixing frame 14 is sleeved outside the support shaft 1510. The vibration mechanism 17 is provided outside the support shaft 1510.

[0029] The first gear 1505 and the third gear 1507 are different in size. Through the transmission of the second gear 1506, the rotation speeds of the first gear 1505 and the third gear 1507 are made different, thereby realizing the differential rotation control of the first connecting shaft 1503 and the third connecting shaft, and realizing the different rotation speeds control of the first rotary cylinder 161 and the second rotary cylinder 162.

[0030] Specifically, as Figures 4-6 shown, the rotary deblocking mechanism 16 includes a first rotary cylinder 161 and a second rotary cylinder 162. The first rotary cylinder 161 is fixedly connected to the end of the first connecting shaft 1503. The second rotary cylinder 162 is fixedly connected to the end of the second connecting shaft 1508. Third bearings 163 are sleeved outside both the first rotary cylinder 161 and the second rotary cylinder 162. A vertical plate 164 is installed outside the third bearings 163.

[0031] The vertical plate 164 is fixedly connected to the back of the rotating filter frame 3. Plug rods 165 are fixedly connected outside both the first rotary cylinder 161 and the second rotary cylinder 162. The plug rods 165 outside the first rotary cylinder 161 and the plug rods 165 outside the second rotary cylinder 162 are arranged staggeredly.

[0032] When the tea mass passes through the second rotary cylinder 162, the plug rods 165 on the surface of the second rotary cylinder 162 insert into the tea mass and push it to move to the right. When the plug rods 165 on the surface of the first rotary cylinder 161 insert into the tea mass, due to the speed of the plug rods 165 on the surface of the first rotary cylinder 161 being greater than the speed of the plug rods 165 on the surface of the second rotary cylinder 162, the speed difference between the two will tear the tea mass.

[0033] Specifically, as Figures 4-5 and Figure 8As shown, the vibration mechanism 17 includes a second extrusion wheel 171 fixedly connected to the outside of the support shaft 1510. A contact plate 172 is provided on the second extrusion wheel 171. A support 173 is fixedly connected to the contact plate 172. A fixing rod 174 is slidably connected through the support 173. The fixing rod 174 is fixedly connected to the fixing frame 14. A circular plate 175 is fixedly connected to the top end of the fixing rod 174. A second spring 176 fixedly connected to the support 173 and the circular plate 175 is sleeved outside the fixing rod 174. A vibration rod 177 provided on the first connecting shaft 1503 and the second connecting shaft 1508 is fixedly connected below the support 173.

[0034] The fixing rod 174 guides the vertical movement of the support 173 and the contact plate 172 to ensure the stable linear movement of the vibration rod 177. During the rotation of the second gear 1506, the contact plate 172, the support 173, and the vibration rod 177 are controlled to move upward through the second extrusion wheel 171. When the protruding part of the second extrusion wheel 171 separates from the contact plate 172, the elastic force of the second spring 176 on the support 173 controls the vibration rod 177 to quickly act downward on the first connecting shaft 1503 and the second connecting shaft 1508, and the vibration acts on the surface of the inserting rod 165 inserted into the tea mass.

[0035] Specifically, as Figures 4-5 and Figure 9 shown, the extrusion contact mechanism 18 includes a push wheel 181 fixedly connected to the outside of the first connecting shaft 1503. A moving rod 182 is slidably connected to the outside of the push wheel 181. A connecting frame 183 is fixedly connected to the bottom end of the moving rod 182. An elastic telescopic rod 184 is fixedly connected to the outside of the connecting frame 183. The elastic telescopic rod 184 is fixedly connected to the outside of the rotating filter frame 3. A knocking rod 185 is fixedly connected to the outside of the connecting frame 183. A linear bearing 186 is slidably connected to the outside of the knocking rod 185. The linear bearing 186 is provided through the outside of the rotating filter frame 3. The knocking rod 185 is provided outside the guiding and dispersing mechanism 19.

[0036] The rotation of the push wheel 181 will squeeze the moving rod 182 to move forward. Cooperating with the elastic force of the elastic telescopic rod 184, the knocking rod 185 can be controlled to perform reciprocating actions back and forth. The linear bearing 186 enables the knocking rod 185 and the moving rod 182 to perform stable linear actions back and forth. The knocking rod 185 acts on the surface of the guide plate 193 to achieve rapid knocking on the guide plate 193.

[0037] Specifically, as Figures 4-5 and Figure 10As shown in the figure, a second magnet 20 is provided on the inner wall of the upper rotating filter frame 3 corresponding to the position of the guiding and spreading mechanism 19. The guiding and spreading mechanism 19 includes five mounting plates 191 fixedly connected to the inner wall of the rotating filter frame 3. The right side surface of the mounting plate 191 is hinged with a first pin shaft 192. A guide plate 193 is mounted outside the first pin shaft 192. A second pin shaft 194 is hinged on each of the five guide plates 193. A linkage rod 195 is provided between the five second pin shafts 194. The knocking rod 185 moves quickly to knock the guide plate 193 to rotate.

[0038] A first magnet 196 is fixedly connected to the front surface of the foremost guide plate 193. The opposite surfaces of the first magnet 196 and the second magnet 20 have opposite magnetic properties. The first magnet 196 and the second magnet 20 drive the guide plate 193 to reset. The guide plate 193 is arranged in an arc shape.

[0039] The guide plate 193 rotates around the first pin shaft 192. The second pin shaft 194 and the linkage rod 195 enable the five guide plates 193 to rotate synchronously. When a knocking action acts on the guide plate 193, it will control the guide plate 193 to rotate quickly backward. The guide plate 193 quickly pushes the tea leaves passing between the guide plates 193 and impacts them, and the dispersion effect between the tea leaves is better.

[0040] Working principle, when in use: Directly put the kneaded tea leaves into the feeding hopper 13, and start the first driving component 6 and the second driving component 1501. The first driving component 6 controls the two rotating rods 9 and the first pressing wheel 10 to rotate through the gearbox 7 and the transmission pulley group 8. The rotation of the first pressing wheel 10 exerts an upward thrust on the rotating filter frame 3, and the first spring 12 exerts a downward elastic force on the rotating filter frame 3. The two cooperate to achieve a vibrating effect on the rotating filter frame 3; The agglomerated tea leaves in the feeding hopper 13 fall on the rotating filter frame 3 and are acted on the tea leaf mass by the continuously vibrating rotating filter frame 3. The tea leaf mass moves rightward and downward. The second driving component 1501 controls the rotation of the first gear 1505, the second gear 1506, and the third gear 1507. Since the first gear 1505 and the third gear 1507 are set to different sizes, the rotation of the first gear 1505 is transmitted to the third gear 1507 through the second gear 1506. The rotation speed of the first gear 1505 is greater than the rotation speed of the third gear 1507. When the tea leaf mass passes through the second rotating cylinder 162, the insertion rod 165 on the surface of the second rotating cylinder 162 inserts into the tea leaf mass and pushes it to move rightward. When the insertion rod 165 on the surface of the first rotating cylinder 161 inserts into the tea leaf mass, since the speed of the insertion rod 165 on the surface of the first rotating cylinder 161 is greater than the speed of the insertion rod 165 on the surface of the second rotating cylinder 162, the speed difference between the two will tear the tea leaf mass and separate it. During the rotation of the second gear 1506, the second pressing wheel 171 controls the contact plate 172, the bracket 173, and the vibrating rod 177 to move upward; After the convex part of the second pressing wheel 171 separates from the contact plate 172, the elastic force of the second spring 176 on the bracket 173 controls the vibration rod 177 to act quickly downward on the first connecting shaft 1503 and the second connecting shaft 1508. The vibration acts on the surface of the insertion rod 165 inserted into the tea mass, making the tearing and separating effect of the tea mass better. After the tea mass is torn and separated, it enters between the guide plates 193. During the rotation of the pushing wheel 181, it will push the moving rod 182 forward. At this time, the knocking rod 185 separates from the guide plate 193. After the convex part of the pushing wheel 181 separates from the moving rod 182, the elastic telescopic rod 184 uses its own elastic force to control the knocking rod 185 to reset. The knocking rod 185 knocks on the surface of the guide plate 193, and the guide plate 193 quickly swings backward. The guide plate 193 quickly pushes the tea backward and impacts on the surface of the rear guide plate 193, so that the tea is quickly shaken and at the same time is pushed and impacted to be dispersed, and the tea falling from the rotating filter frame 3 is collected.

[0041] The rotating filter frame 3 filters the tea on its upper side, and the qualified products are left on the rotating filter frame 3, and the residues flowing down after filtration enter the collection box 5.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
