Description

Technical Field

[0001] This invention relates to the field of tea processing equipment technology, specifically a tea uniform stacking device and method. Background Technology

[0002] In the refining and processing of tea, blending is a crucial step that involves mixing teas from different batches, grades, or origins in a specific ratio to ensure the consistency of the finished tea's quality. Traditional blending methods often employ manual turning or simple mechanical agitator conveyors, which suffer from high labor intensity, low efficiency, and uneven mixing.

[0003] In recent years, some automated mixing equipment has emerged, such as using rotating drums or lifting and turning mechanisms to repeatedly turn and mix tea leaves in a closed container.

[0004] Existing equipment has a complex structure, occupies a large area, and often adopts an open or semi-open structure, which easily introduces external impurities and affects the purity of the finished tea. After the tea is evenly piled, it needs to be taken out of the equipment and transferred to the packaging process, which increases the material turnover links, which is not only inefficient, but also easily causes secondary pollution or breakage of the tea. Summary of the Invention

[0005] The purpose of this invention is to provide a tea leaf uniform stacking device and method to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tea leaf uniform stacking device, comprising: The bracket serves as a supporting foundation; A uniform feeding cylinder is mounted on the support, with one end being the feeding port and the other end being the transfer port. A uniform feeding channel for the tea leaves to move back and forth is formed between the feeding port and the transfer port. When the uniform feeding cylinder rotates, it changes the direction of the uniform feeding channel, and the tea leaves change their flow direction under the action of gravity. The tea barrel is detachably connected to the inlet end of the uniform material cylinder. When connected, the tea barrel serves as an extension of the uniform material channel, used to accommodate and receive the tea leaves flowing back from the uniform material channel during the uniform material mixing process. After the uniform material mixing is completed, the tea barrel serves as a direct packaging container for the finished tea.

[0007] Furthermore, including: The first material feeding component is located inside the material feeding cylinder and near the material inlet end, and moves along the length direction of the material feeding cylinder.

The tea barrel and the inner cylinder are fixed by a self-locking component.

[0009] Furthermore, the first feeding assembly includes: The first hopper is located between the inner cylinder and the material distribution assembly, with the smaller diameter end of the first hopper facing the material distribution assembly; Several columns are fixedly connected between the inner cylinder and the first hopper, and a material passage gap is formed between adjacent columns. When a lateral channel is formed between the first material passage component and the inner wall of the material uniform cylinder, the tea leaves in the material uniform cylinder can only be discharged back into the inner cylinder through the material passage gap.

[0010] Furthermore, it includes a lifting rod and a second telescopic component. The lifting rod is slidably inserted through the central end of the equalizing cylinder, and the second tea sprinkler is fixed to the end of the lifting rod. The second telescopic component is fixed to the equalizing cylinder, and its driving end is connected to the lifting rod for driving the distributing assembly to reciprocate along the equalizing channel. The distributing assembly includes: The first tea sprinkler is fixedly installed in the material distribution channel. The first tea sprinkler has an umbrella-shaped structure with its tip facing the small-diameter end of the first hopper. It is used to receive and disperse the tea leaves falling from the first hopper. The second tea sprinkler is fixed on the side of the first tea sprinkler away from the first hopper. The second tea sprinkler has an umbrella-shaped structure with its tip facing the transfer end.

[0011] Furthermore, the second material feeding assembly includes: The second hopper is fixedly installed inside the equalizing cylinder, with the large-diameter end of the second hopper facing the first tea sprinkler and the small-diameter end facing the transfer end. The third hopper is fixedly installed inside the equalizing cylinder and located on the side of the second hopper near the transfer end. The large-diameter end of the third hopper faces the transfer end, and the small-diameter end is connected to and communicates with the small-diameter end of the second hopper. The second tea sprinkler is movably inserted between the small-diameter end of the second and third hoppers, and is used to block or open the small-diameter end.

[0012] Furthermore, the transfer end of the material equalization cylinder is provided with an umbrella-shaped ramp, the tip of which faces the material distribution component; a dust cover is fitted on the outer wall of the material equalization cylinder, and a debris removal cavity is formed between the dust cover and the outer wall of the material equalization cylinder. The uniform material cylinder has several first and second drain ports on its cylinder wall. The first drain ports are located near the transfer end, and the second drain ports are located near the material inlet end. Both the first and second drain ports are sealed with filter screens and are connected to the impurity discharge chamber.

[0013] Furthermore, a rotating shaft is mounted on the support and fixed to the material equalization cylinder; the rotating shaft is a hollow shaft, with an air inlet pipe coaxially passing through one of the rotating shafts and an exhaust pipe coaxially passing through the other rotating shaft. One end of the air inlet pipe is an air inlet end and is provided with an air filter layer, and the other end is an air outlet end and extends into the interior of the uniform material cylinder; One end of the exhaust pipe is the exhaust end and is connected to the air pump, and the other end is the air inlet end and is connected to a three-way pipe.

[0014] Furthermore, both the second and third hoppers are made of a breathable material, which is a mesh structure woven from steel wire, with a mesh size smaller than that of tea leaves and allowing dust and debris to pass through.

[0015] A method for evenly stacking tea leaves includes the following steps: S1: Connect the tea barrel, position the tea barrel below the material outlet end of the uniform material cylinder, drive the telescopic component to extend, and cooperate with the self-locking component to fix the tea barrel and the material outlet end of the uniform material cylinder in a fixed connection. S2: Initial feeding and uniform stacking: Drive the uniform stacking cylinder to rotate so that the feed inlet end faces upward, and feed the tea leaves from the tea barrel into the uniform stacking channel through the feed inlet end for initial uniform stacking until the tea leaves are piled up to the transfer end; S3: Secondary uniform mixing, drive the uniform mixing cylinder to rotate so that the transfer end faces upward. Under the action of gravity, the tea leaves flow from the transfer end to the feed inlet end and return to the tea barrel, completing the secondary uniform mixing. S4: Cyclicly mix the tea leaves, repeating steps S2 and S3 several times until the tea leaves are evenly mixed. S5: Unloading, drive the material distribution cylinder to rotate so that the material outlet end faces downward, release the locking of the telescopic component and the self-locking assembly, so that the tea barrel is separated from the material distribution cylinder, and unloading is completed.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting up a first material feeding component, a material distributing component, and a second material feeding component, enables tea leaves to undergo multiple, multi-dimensional mixing processes of "aggregation-dispersion-reaggregation-redispersion" during reciprocating motion. The mixing path is bidirectional and significantly improves the uniform stacking effect. The tea barrel serves as both a container for tea leaves during the uniform stacking process and a final packaging container for the finished product, realizing a continuous operation process of "one-time filling, multiple uniform stacking, and direct packaging." This eliminates intermediate material transfer links and reduces manual intervention and the risk of secondary contamination. By utilizing the negative pressure generated by air extraction, dust, debris, and other impurities in the tea leaves can be effectively separated and discharged, achieving integrated uniform stacking and purification operations and improving the purity and quality of the finished tea.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] See Figures 1-7 The present invention provides a technical solution: a tea leaf uniform stacking device, comprising: Bracket 101 serves as the supporting foundation; The uniform feeding cylinder 103 is mounted on the support 101. One end of it is the feeding port 104, and the other end is the transfer end 105. The feeding port 104 and the transfer end 105 form a uniform feeding channel for the tea leaves to move back and forth. When the uniform feeding cylinder 103 rotates, it changes the direction of the uniform feeding channel, and the tea leaves change their flow direction under the action of gravity. Tea barrel 1 is detachably connected to the material inlet end 104 of the uniform material cylinder 103. When connected, tea barrel 1 serves as an extension of the uniform material channel and is used to accommodate and receive the tea leaves flowing back from the uniform material channel during the uniform material mixing process. After the uniform material mixing is completed, tea barrel 11 serves as a direct packaging container for the finished tea.

[0021] A support frame 101 is placed on the ground. A rotating shaft 102 is mounted on the support frame 101, and a material distribution cylinder 103 is fixed on the rotating shaft 102. One end of the material distribution cylinder 103 is a material inlet end 104 for loading and unloading, and the other end is a transfer end 105 for tea leaves to temporarily stop. By rotating the material distribution cylinder 103, when the material inlet end 104 is on top, the tea leaves enter from the material inlet end 104, then pass through the material distribution channel to reach the transfer end 105; when the transfer end 105 is on top, the tea leaves pass through the material distribution channel from the transfer end 105 to the material inlet end 104. Under the premise of one loading, the tea leaves are driven back and forth through the material distribution channel multiple times, thereby realizing multiple material distribution operations without endlessly increasing the length of the material distribution channel, improving material distribution efficiency while reasonably controlling the height of the equipment.

[0022] The power source for driving the uniform cylinder 103 to rotate can be manual rotation or rotational power component (not shown in the figure), such as a combination structure of motor, belt and pulley. One of the rotating shafts 102 is fitted with a pulley, the motor is mounted on the bracket 101, and the output shaft of the motor is fitted with a pulley. The two pulleys are connected by a belt.

[0023] In one embodiment, the first feeding component is disposed inside the uniform feeding cylinder 103 and near the feeding port end 104, and moves along the length direction of the uniform feeding cylinder 103. The second feeding assembly is fixed inside the feeding cylinder 103 and is used to collect and receive tea leaves from one end. The material distribution component 4 is disposed inside the material distribution cylinder 103 and moves along the length of the material distribution cylinder 103; the material distribution component 4 is located between the first material conveying component and the second material conveying component; it is used to circumferentially disperse the tea leaves falling from the first material conveying component or the second material conveying component. When the uniform material cylinder 103 is in the first rotation position and the material distribution component 4 actively abuts against the first material conveying component, the abutting end of the first material conveying component is closed, and the first material conveying component is in contact with the inner wall of the uniform material cylinder 103; when the uniform material cylinder 103 is in the second rotation position and the first material conveying component actively abuts against the material distribution component 4, the abutting end of the first material conveying component is closed, and a lateral channel for tea leaves to pass through is formed between the first material conveying component and the inner wall of the uniform material cylinder 103.

[0024] The tea barrel 1 has a second flange 11 around its opening end, and the second flange 11 has several insertion holes 12.

[0025] Preparation: Pour multiple batches of tea leaves into tea barrel 1 according to the specified ratio. At this point, the tea leaves will naturally be layered in tea barrel 1, requiring further homogenization, corresponding to the homogenization process in traditional tea making. For example, three batches of tea leaves are poured into tea barrel 1 in a 1:1:1 ratio, resulting in a total of 5 barrels.

[0026] The uniform feeding cylinder 103 includes a neck 1031 and a uniform feeding section 1032 connected together. The feeding port 104 is located at the end of the neck 1031 away from the uniform feeding section 1032. Tea leaves enter and exit the uniform feeding section 1032 from the neck 1031. An inner cylinder 2 is slidably sleeved inside the neck 1031 (the two are tightly connected to prevent tea leaves from falling into the gap between them). The inner cylinder 2 is provided with a first feeding component at one end near the uniform feeding section 1032, and the other end extends to the outside of the neck 1031. Several telescopic components 22 are provided on the uniform feeding cylinder 103 near the feeding port 104. The driving end of the telescopic component 22 passes through the first flange 21 of the inner cylinder 2 and continues to extend for subsequent insertion into the insertion hole 12 of the tea canister 1. The driving end of the telescopic component 22 is fixedly connected to the first flange 21. On the one hand, the position of the first feeding component in the uniform feeding section 1032 can be controlled by the inner cylinder 2. On the other hand, the height of the inner cylinder 2 can be controlled to achieve docking and separation with the tea canister 1.

[0027] In use, with the feed inlet end 104 facing downwards, the tea barrel 1 is placed with its opening facing upwards in the positioning groove reserved at the bottom of the support 101 by manual operation or by the previous process equipment. The positioning groove fits perfectly with the bottom of the tea barrel 1, thus positioning the tea barrel 1. At this time, the axis of the tea barrel 1 is collinear with the uniform feed cylinder 103. The driving end of the telescopic component 22 extends downwards and inserts into the insertion hole 12 of the tea barrel 1, causing the first flange 21 and the second flange 11 to fit tightly together. The self-locking component locks the driving end of the telescopic component 22 and the tea barrel 1, that is, locks the neck 1031 and the tea barrel. The docking of the tea barrel 1 and the uniform feed cylinder 103 is completed. At this time, the distance between the first feeding component and the distributing component 4 is at its maximum. This state is the initial position of the distributing component 4.

[0028] The first material feeding assembly includes a first material hopper 32 and several columns 31. The columns 31 are fixedly connected between the inner cylinder 2 and the first material hopper 32. The small-diameter end of the first material hopper 32 is far away from the columns 31, and the large-diameter end of the first material hopper 32 is adapted to the diameter of the cylinder neck 1031, so that the two can fit together when they are connected.

[0029] The material distribution unit 1032 is further provided with a material distribution component 4 and a second material conveying component, with the material distribution component 4 located between the first material conveying component and the second material conveying component. Specifically, the material distribution component 4 includes a first tea sprinkler 41, a second tea sprinkler 42, and a lifting rod; both the first tea sprinkler 41 and the second tea sprinkler 42 are umbrella-shaped, and the tips of the umbrella shapes are opposite to each other; the tip of the first tea sprinkler points towards the inner cylinder 2; a telescopic component 2 52 is vertically provided in the through hole at the bottom of the material distribution cylinder 103, and the driving end of the telescopic component 2 52 is connected to the second tea sprinkler 42 through a lifting rod 51, which is slidably inserted into the through hole; the material distribution component 4 is located between the first material conveying component and the second material conveying component; it is used to circumferentially disperse the tea leaves falling from the first material conveying component or the second material conveying component. Specifically, the second material feeding assembly includes a second hopper 61 and a third hopper 62; the small-diameter ends of the second hopper 61 and the third hopper 62 are connected and fitted together, and the large-diameter ends are fixedly fitted to the inner wall of the material equalization section 1032; the large-diameter end of the second hopper 61 faces the material distribution assembly 4.

[0030] After the tea barrel 1 and the equalizing cylinder 103 are connected, the telescopic component 52 extends to drive the lifting rod 51 and the distributing component 4 to move upwards synchronously until the first tea sprinkler 41 plugs in and seals the outlet of the first hopper 32, and the equalizing channel is closed. Only then can the equalizing cylinder 103 be driven to rotate around the rotating shaft 102, and the tea barrel 1 rotates to the highest point, after which the tea leaves have filled the inner cylinder 2. Only then can the telescopic component 52 retract and reset. After resetting, the outlet of the first hopper 32 opens (the equalizing channel opens), and the tea leaves in the tea barrel 1 pass through the outlet of the first hopper 32 and fall onto the first tea sprinkler 41. The tea leaves are evenly dispersed 360 degrees along the outer surface of the first tea sprinkler 41 and fall onto the second hopper 61. After passing through the second hopper 61, they fall onto the bottom of the equalizing cylinder 103 until the tea leaves in the tea barrel 1 have completely fallen to the bottom of the equalizing cylinder 103 (below the second distributing component), completing one distribution cycle. In particular, the tea leaves may arch and block the outlet of the second hopper 61 of the first hopper 32. The arch can be broken by the lifting and distributing components 4 to ensure that the tea leaves fall smoothly.

[0031] Secondary material distribution: The drive cylinder 103 rotates around the shaft 102, causing the tea barrel 1 to rotate to its lowest point, filling the third hopper 62 with tea leaves. To ensure more even material distribution, the telescopic component 2 52 can be retracted before the second rotation, allowing the second tea dispenser 42 to plug into and seal the small-diameter end of the second hopper 61 (the second hopper 61 and the third hopper 62 share a small-diameter end). After the tea barrel 1 rotates to its lowest point, the telescopic component 2 52 extends and returns to its initial state. The telescopic component 1 22 retracts, causing the inner cylinder 2 to retract back to the neck 1031. The inner cylinder 2 moves the column 31 and the first hopper 32 closer to the first tea dispenser 41 until the outlet of the first hopper 32 is inserted into and attached to the first tea dispenser 41 (the end with the pointed tip). At this time, the column 31 enters the equalizing cylinder 103, and the equalizing cylinder 103 is connected to the inner cylinder 2 through the gap between the adjacent columns 31. The tea leaves in the third hopper 62 pass through the third hopper 62 and fall onto the second tea dispenser 42, then fall into the gap between the adjacent columns 31, pass through the gap and the inner cylinder 2 and return to the tea barrel 1. The second distribution is completed. One material distribution cycle is completed by the first and second material distributions. Multiple material distribution cycles are achieved by repeatedly turning the material distribution cylinder 103 to fully mix different batches of tea. After the last material distribution cycle is completed, the tea barrel 1 is at its lowest point. The telescopic component 22 extends and drives the tea barrel 1 to fall into the positioning groove. The self-locking component unlocks, the telescopic component 22 retracts and resets, and the tea barrel 1 is removed manually or by unloading equipment. Then, in the next process, the tea barrel 1 is covered with a sealing cap. There is no need to refill the tea leaves in the tea barrel 1. The entire process of material distribution and packaging is completed in one filling. It can also be more conveniently assembled into an automated production line, reducing the transformation cost and technical difficulty of existing factories.

[0032] Figure 3 and Figure 4 The self-locking component is a nut 23. The drive end of the telescopic member 22 is provided with an external thread. After the drive end of the telescopic member 22 passes through the first flange 21 and the second flange 11, the nut 23 is fitted onto the external thread of the drive end of the telescopic member 22. The second flange 11 is clamped by tightening the nut 23 and the first flange 21.

[0033] In one implementation, Figure 4 The tea in the tea barrel 1 contains a certain amount of dust and debris. If it is mixed with the tea, it will reduce the quality of the tea. In order to clean the dust and debris, a slope is provided at the transfer end 105 of the uniform material cylinder 103. The slope is umbrella-shaped and the tip is facing the material distribution component 4. A dust cover 106 is fitted on the outer wall of the uniform material section 1032. A debris removal cavity 107 is formed between the dust cover 106 and the uniform material section 1032. Several first drain outlets 108 are provided near the slope in the material leveling section 1032, and several second drain outlets 109 are provided at the other end of the material leveling section 1032. Filter screens are sealed in both the first drain outlets 108 and the second drain outlets 109. Both the first drain outlets 108 and the second drain outlets 109 are connected to the impurity discharge chamber 107. An air inlet pipe 81 is coaxially inserted through a rotating shaft 102 on one side of the support 101, and an exhaust pipe 82 is coaxially inserted through a rotating shaft 102 on the other side. An air filter layer is provided in the air inlet end of the air inlet pipe 81, and the air outlet extends through the impurity discharge chamber 107 to the inside of the uniform material cylinder 103. The second funnel 61 and the third funnel 62 are both made of breathable material, such as a dense mesh woven from fine steel wire, which has both support and breathability. The mesh size on the second funnel 61 and the third funnel 62 must be very small to avoid the whole tea leaves being broken when inserted vertically into the mesh. Dust, gas and fine debris can pass through the mesh, or only dust and gas can pass through the mesh. The air inlet end of the exhaust pipe 82 is equipped with a three-way pipe. The first branch pipe 83 of the three-way pipe extends through the impurity discharge chamber 107 into the uniform material cylinder 103 and is located in the gap between the second hopper 61 and the third hopper 62. The second branch pipe 84 is connected to the impurity discharge chamber 107. The air outlet end of the exhaust pipe 82 is connected to the suction and discharge pipe of the suction pump 85 through a rotary joint. Start the air pump 85, the second branch pipe 84 draws out the dust and debris in the discharge chamber 107, and the first branch pipe 83 draws out the dust and debris inside the uniform material cylinder 103 and located between the second funnel 61 and the third funnel 62. During the extraction process, air is continuously supplied to the uniform material section 1032 and the discharge chamber 107 through the air inlet pipe 81 to maintain air pressure balance.

[0034] As the tea leaves continuously pass through the uniform material channel, the vacuum pump 85 is started intermittently at preset intervals to change the gas flow direction in the uniform material section 1032, thereby achieving the arch-breaking operation at the second funnel 61 or the third funnel 62. After the tea leaves have completely passed through the uniform material channel and are concentrated at one end of the uniform material cylinder 103, the vacuum pump 85 can continue to run for a short period of time to remove dust and debris.

[0035] In order to better extract the debris and dust discharged from the first drain outlet 108 and the second drain outlet 109, an extension pipe can be connected again at the second branch pipe 84. For example, two extension pipes can be connected, with one air inlet located near the first drain outlet 108 and the other extension pipe located near the second drain outlet 109.

[0036] The filter only allows fine debris, dust, and gas to pass through.

[0037] Both telescopic component 1 (22) and telescopic component 2 (52) can be electric push rods. The power supply lines are laid out according to the actual situation, which will not be described in detail here.

[0038] A method for evenly stacking tea leaves includes the following steps: S1: Connect the tea barrel 1, position the tea barrel 1 below the material outlet end 104 of the uniform material cylinder 103, drive the telescopic component 22 to extend, and cooperate with the self-locking component to fix the tea barrel 1 to the material outlet end 104 of the uniform material cylinder 103. S2: Initial feeding and uniform stacking: drive the uniform stacking cylinder 103 to rotate so that the feed inlet end 104 faces upward, and feed the tea leaves from the tea barrel 1 into the uniform stacking channel through the feed inlet end 104 for initial uniform stacking until the tea leaves are piled up to the transfer end 105. S3: Secondary uniform mixing, drive the uniform mixing cylinder 103 to rotate so that the transfer end 105 faces upward. Under the action of gravity, the tea leaves flow from the transfer end 105 to the feed inlet end 104 and return to the tea barrel 1 to complete the secondary uniform mixing. S4: Cyclicly mix the tea leaves, repeating steps S2 and S3 several times until the tea leaves are evenly mixed. S5: Unloading, drive the uniform material cylinder 103 to rotate so that the material outlet end 104 faces downward, release the locking of the telescopic member 22 and the self-locking assembly, so that the tea barrel 1 is separated from the uniform material cylinder 103, and unloading is completed.
