Description

Technical Field

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

[0002] Rolling is one of the core steps in tea processing (especially for green tea, black tea, oolong tea, etc.). It squeezes the tea leaves through mechanical force to rupture the mesophyll cell walls and release 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 strips (such as the "dragonfly head" of oolong tea and the "tight and thin strips" of black tea), thereby enhancing the appearance and commercial value of the tea.

[0003] The rolled tea leaves need to be screened to remove the tea stems and debris to improve the quality of the tea.

[0004] In the field of tea processing, if the tea balls formed after the rolling process are directly subjected to vibration screening, although vibration screening itself has a certain dispersion function, for tea balls with high viscosity and high humidity, especially oolong tea, black tea and other teas that have been heavily rolled, it is difficult to achieve complete dispersion of the tea balls by relying solely on vibration screening.

[0005] The acceleration of vibration screening is limited, and it mainly relies on the collision between the weight of the tea leaves and the screen to achieve dispersion. The shear force for dense tea clumps is obviously insufficient, which causes the undeagglomerated tea clumps to clog the upper sieve holes, especially the large-aperture screens, thereby reducing the effective screening area. Some tea leaves cannot be accurately graded according to particle size due to clumping, affecting the effect and efficiency of tea grading.

[0006] Based on this, the present invention designs a double-layer tea shaking and screening 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, and the guide plate is set to an arc shape.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. The present invention utilizes a second drive assembly, a first gear, a second gear, a third gear, a first rotating drum, a second rotating drum, and an insertion rod. The second drive assembly precisely controls the rotation of the first gear, the second gear, and the third gear. Because the first gear and the third gear are set to different sizes and are driven by the second gear, a transmission ratio is achieved in which the speed of the first gear is greater than the speed of the third gear. This design enables the insertion rod on the surface of the second rotating drum to smoothly penetrate the tea clump and push it to the right when the tea clump passes through the second rotating drum. When the insertion rod on the surface of the first rotating drum penetrates the tea clump, the speed of the insertion rod on the first rotating drum is greater than the speed of the insertion rod on the surface of the second rotating drum. The speed difference between the two produces a strong tearing effect on the tea clump, effectively separating the tea clumps. Combined with the vibration of the rotating filter frame itself, the dispersion effect of the tea clumps is further enhanced. This composite action mechanism not only overcomes the defect of insufficient shear force on compact tea clumps in traditional vibration screening, but also avoids the problem of reduced screening area caused by tea clumps blocking the sieve holes, ensuring that tea can be accurately classified according to particle size, thereby significantly improving the screening efficiency and effect of tea clumps.

[0021] 2. In the present invention, a second extrusion wheel, a bracket, a second spring, and a vibration rod are adopted. The second gear will drive the second extrusion wheel to rotate synchronously during the rotation process, and the second extrusion wheel will control the contact plate, the bracket and the vibration rod to move upward. When the raised part of the second extrusion wheel is separated from the contact plate, the elastic force of the second spring on the bracket will quickly control the vibration rod to act downward on the first connecting shaft and the second connecting shaft. This vibration effect will be transmitted to the surface of the insertion rod inserted into the tea ball, thereby reducing the friction inside the tea ball, and the tearing and separation effect of the tea ball is significantly improved. The tea ball can be more thoroughly dispersed into smaller clumps. Since the vibration effect reduces the friction inside the tea ball, it also effectively reduces the chance of tea leaves being broken during the tearing process, thereby better maintaining the integrity of the tea. The present invention realizes efficient and gentle dispersion of tea balls through ingenious structural design and synergistic action of components, which not only improves the screening efficiency and effect, but also effectively protects the quality of the tea.

[0022] 3. In the present invention, a push wheel, a moving rod, a knocking rod, an elastic telescopic rod, a guide plate, a first magnetic block and a second magnetic block are adopted. The push wheel pushes the moving rod forward during rotation. At this time, the knocking rod and the guide plate are in a separated state. When the raised part of the push wheel is separated from the moving rod, the elastic telescopic rod uses its own elastic force to quickly control the knocking rod to reset, and the knocking rod knocks forcefully on the surface of the guide plate. This knocking force causes the guide plate to swing backward quickly, thereby pushing the tea leaves backward and hitting the surface of the guide plate on the rear side. In this process, the tea leaves are not only shaken rapidly, but also affected by the impact force, thereby achieving further dispersion of the tea leaves. This dispersion method combining pushing and impact not only significantly improves the dispersion efficiency and effect of the tea leaves, but also because the impact force directly acts on the tea leaves, avoids excessive friction and extrusion that may exist in the traditional dispersion method, thereby effectively reducing the chance of damage to the tea leaves during the dispersion process, and better maintaining the integrity and quality of the tea leaves.

The back of the differential control mechanism 15 is fixedly connected to a rotating deblocking mechanism 16 arranged on the back of the rotating filter frame 3. A vibration mechanism 17 is provided outside the differential control mechanism 15. An extrusion contact mechanism 18 is provided outside the rotating deblocking mechanism 16. A guiding and pushing mechanism 19 installed in the rotating filter frame 3 is provided on the side of the extrusion contact mechanism 18.

[0037] The rotating filter frame 3 can be rotated up and down inside the side frame 1 through the rotating shaft 2. The first driving assembly 6 controls the two rotating rods 9 and the first extrusion wheel 10 to rotate through the gearbox 7 and the transmission wheel group 8. The rotation of the first extrusion wheel 10 applies an upward thrust to the rotating filter frame 3, and 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.

[0038] Specifically, such as Figure 1-3 As shown, a rotating shaft 2 is rotatably connected between the rotating filter frame 3 and the side frame 1, a collecting frame 5 is fixedly connected to the bottom of the side frame 1, and the collecting frame 5 is arranged in the base frame 4. The rotating filter frame 3 is set to an inclined shape, and a lower hopper 13 is fixedly connected to the side frame 1. The outlet position of the lower 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, and the top end of the first spring 12 is fixedly connected to a horizontal plate 11 provided on the inner wall of the side frame 1.

[0039] The first spring 12 applies a downward elastic force to the rotating filter frame 3 , so as to facilitate the control of the rotating filter frame 3 to reset.

[0040] Specifically, such as Figure 4-5 and Figure 7 As shown, the differential control mechanism 15 includes a second drive component 1501, and the second drive component 1501 is fixedly connected to an extension rod 1502 installed outside the fixed frame 14. The output shaft of the second drive component 1501 is fixedly connected to a first gear 1505, the side of the first gear 1505 is meshed with a second gear 1506, the side of the second gear 1506 is meshed with a third gear 1507, and the back of the first gear 1505 is fixedly connected to a first connecting shaft 1503, and the outer sleeve of the first connecting shaft 1503 is provided with a first bearing 1504.

[0041] The back of the third gear 1507 is fixedly connected to the second connecting shaft 1508, and the second connecting shaft 1508 is provided with a second bearing 1509 on its outer sleeve. The first bearing 1504 and the second bearing 1509 are both fixedly connected to the fixed frame 14. The first connecting shaft 1503 and the second connecting shaft 1508 are both connected to the outside of the rotating deblocking mechanism 16. The back of the second gear 1506 is fixedly connected to the support shaft 1510, and the support shaft 1510 is provided with a support seat 1511 on the fixed frame 14 on its outer sleeve. The vibration mechanism 17 is provided outside the support shaft 1510.

[0042] The first gear 1505 and the third gear 1507 are of different sizes. Through the transmission of the second gear 1506, the first gear 1505 and the third gear 1507 have different rotation speeds, thereby controlling the differential rotation of the first connecting shaft 1503 and the third connecting shaft, and controlling the different rotation speeds of the first rotating drum 161 and the second rotating drum 162.

[0043] Specifically, such as Figure 4-6 As shown, the rotating deblocking mechanism 16 includes a first rotating drum 161 and a second rotating drum 162. The first rotating drum 161 is fixedly connected to the end of the first connecting shaft 1503, and the second rotating drum 162 is fixedly connected to the end of the second connecting shaft 1508. The first rotating drum 161 and the second rotating drum 162 are both provided with a third bearing 163 on the outside, and a vertical plate 164 is installed on the outside of the third bearing 163.

[0044] The vertical plate 164 is fixedly connected to the back of the rotating filter frame 3. The first drum 161 and the second drum 162 are fixedly connected with the insertion rods 165. The insertion rods 165 outside the first drum 161 and the insertion rods 165 outside the second drum 162 are staggered.

[0045] When the tea ball passes through the second rotating drum 162, the insertion rod 165 on the surface of the second rotating drum 162 inserts into the tea ball and pushes it to the right. When the insertion rod 165 on the surface of the first rotating drum 161 inserts into the tea ball, since the speed of the insertion rod 165 on the surface of the first rotating drum 161 is greater than the speed of the insertion rod 165 on the surface of the second rotating drum 162, the speed difference between the two will tear the tea ball.

[0046] Specifically, such as Figure 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 bracket 173 is fixedly connected to the contact plate 172, a fixing rod 174 is slidably connected through the bracket 173, the fixing rod 174 is fixedly connected to the fixing frame 14, the top of the fixing rod 174 is fixedly connected to the circular plate 175, the outer sleeve of the fixing rod 174 is provided with a second spring 176 fixedly connected to the bracket 173 and the circular plate 175, and a vibration rod 177 provided on the first connecting shaft 1503 and the second connecting shaft 1508 is fixedly connected under the bracket 173.

[0047] The fixed rod 174 guides the vertical movement of the bracket 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 second extrusion wheel 171 controls the contact plate 172, the bracket 173 and the vibration rod 177 to move upward. When the raised part of the second extrusion wheel 171 is separated 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, and the vibration acts on the surface of the insertion rod 165 inserted into the tea ball.

[0048] Specifically, such as Figure 4-5 and Figure 9 As shown, the extrusion contact mechanism 18 includes a push wheel 181 fixedly connected to the outside of the first connecting shaft 1503, and a moving rod 182 is slidably connected to the outside of the push wheel 181. The bottom end of the moving rod 182 is fixedly connected to a connecting frame 183, and 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, and 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 arranged through the outside of the rotating filter frame 3, and the knocking rod 185 is arranged outside the guiding pushing mechanism 19.

[0049] The rotation of the push wheel 181 will squeeze the moving rod 182 to move forward, and the elastic force of the elastic telescopic rod 184 can control the knocking rod 185 to perform reciprocating motion back and forth. The linear bearing 186 enables the knocking rod 185 and the moving rod 182 to perform stable forward and backward linear motion. The knocking rod 185 acts on the surface of the guide plate 193 to achieve rapid knocking of the guide plate 193.

[0050] Specifically, such as Figure 4-5 and Figure 10As shown, a second magnetic block 20 is provided on the inner wall of the upper rotating filter frame 3 corresponding to the position of the guiding and pushing mechanism 19. The guiding and pushing mechanism 19 includes five mounting plates 191 fixedly connected to the inner wall of the rotating filter frame 3. The right side of the mounting plate 191 is hinged to the first pin 192. A guide plate 193 is installed outside the first pin 192. The five guide plates 193 are all hinged with a second pin 194. A linkage rod 195 is provided between the five second pins 194, and the knocking rod 185 moves quickly to knock the guide plate 193 to rotate.

[0051] The front side of the guide plate 193 at the front is fixedly connected to the first magnetic block 196. The opposite surfaces of the first magnetic block 196 and the second magnetic block 20 have opposite magnetism. The first magnetic block 196 and the second magnetic block 20 drive the guide plate 193 to reset. The guide plate 193 is set to an arc shape.

[0052] The guide plates 193 rotate around the first pin 192, and the second pin 194 and the linkage rod 195 make the five guide plates 193 rotate synchronously. When the knocking action is on the guide plates 193, the guide plates 193 will be controlled to rotate backward quickly. The guide plates 193 will quickly push and hit the tea leaves passing between the guide plates 193, and the dispersion effect between the tea leaves will be better.

[0053] Working principle, when using:

[0054] The rolled tea leaves are directly placed into the lower hopper 13, and the first drive assembly 6 and the second drive assembly 1501 are started. The first drive assembly 6 controls the two rotating rods 9 and the first extrusion wheel 10 to rotate through the gearbox 7 and the transmission wheel group 8. The rotation of the first extrusion wheel 10 applies an upward thrust to the rotating filter frame 3, and 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;

[0055] The tea leaves in the lower hopper 13 fall onto the rotating filter frame 3, which is constantly shaken and acts on the tea leaves. The tea leaves move to the lower right, and the second driving assembly 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 first gear 1505 is transmitted to the third gear 1507 through the second gear 1506. The speed of the first gear 1505 is greater than the speed of the third gear 1507. When the tea leaves pass through the second rotating drum 162, the insertion rod 165 on the surface of the second rotating drum 162 inserts into the tea leaves and pushes them to the right. When the insertion rod 165 on the surface of the first rotating drum 161 inserts into the tea leaves, since the speed of the insertion rod 165 on the surface of the first rotating drum 161 is greater than the speed of the insertion rod 165 on the surface of the second rotating drum 162, the speed difference between the two will tear the tea leaves apart. During the rotation of the second gear 1506, the second squeezing wheel 171 controls the contact plate 172, the bracket 173 and the vibration rod 177 to move upward;

[0056] When the raised portion of the second extruding 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 quickly act downward on the first connecting shaft 1503 and the second connecting shaft 1508, and the vibration acts on the surface of the insertion rod 165 inserted into the tea ball, so that the tearing and separation effect of the tea ball is better, and the torn and separated tea ball enters between the guide plates 193. The rotation of the push wheel 181 will push the moving rod 182 to move forward. At this time, the knocking rod 185 is separated from the guide plate 193. When the raised portion of the push wheel 181 is separated from the moving rod 182, the elastic telescopic rod 184 uses its own elastic force to control the knocking rod 185 to reset, and the knocking rod 185 knocks on the surface of the guide plate 193, and the guide plate 193 swings backward quickly. The guide plate 193 quickly pushes the tea leaves backward to hit the surface of the guide plate 193 on the rear side, so that the tea leaves are quickly shaken and pushed and dispersed, and the tea leaves that slipped out of the rotating filter frame 3 are collected.

[0057] The rotating filter frame 3 filters the tea leaves on its upper side, and the qualified products are left on the rotating filter frame 3, and the residue flowing down after filtration enters the collection frame 5.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
