Description

Technical Field

[0001] This utility model relates to the field of tea production technology, specifically to a tea uniform stacking machine. Background Technology

[0002] Blending tea leaves is a crucial step in the refined tea production process, playing a vital role in ensuring the final quality of the tea. During processing, due to the diversity of raw material sources, different harvest times, and variations in initial processing techniques, even teas of the same variety can exhibit differences in color, aroma, taste, and appearance between different batches. The main purpose of the blending process is to further mix the refined tea batches in a reasonable proportion, integrating the advantages of each batch and compensating for their shortcomings, resulting in an overall tea that achieves a uniform color, harmonious aroma, mellow taste, and consistent appearance.

[0003] Currently, the most common tea blending machines on the market mainly consist of a feeding conveyor belt, a vibrating hopper, and a feeding conveyor belt. In operation, the feeding conveyor belt first feeds the processed tea leaves into the vibrating hopper. Then, the vibrating hopper vibrates and mixes the tea leaves. Finally, the vibrating hopper pours the tea leaves onto the feeding conveyor belt below. The feeding conveyor belt moves at a constant speed, conveying the mixed tea leaves to the next production equipment to continue the subsequent tea production and processing flow.

[0004] However, this tea mixing machine mainly relies on the vibration of the vibrating hopper to achieve tea mixing, and this single mixing method has obvious limitations. When a large amount of tea is added, the tea leaves will be tightly compressed together in the vibrating hopper, forming a relatively dense pile. In this case, the movement space of the tea leaves is greatly restricted, making it difficult for them to roll freely and spread fully within the hopper, resulting in a significant reduction in the mixing effect.

[0005] In view of the above problems, it is necessary to develop a tea blending machine with a more efficient mixing function. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a tea blending machine, which can at least solve the technical problem of how to improve the mixing effect of tea.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a tea leaf blending machine, comprising:

[0010] The box body has at least two vertically spaced partition assemblies to divide the internal space of the box body into at least two mixing chambers. The top of the box body has a feed inlet communicating with the uppermost mixing chamber, and the partition assembly has a discharge outlet.

[0011] An opening and closing device is installed at the discharge port of the box and is used to control the opening and closing of the discharge port;

[0012] The feeding device is installed outside the box and connected to the inlet. The feeding device is used to feed tea into the inlet.

[0013] The dispersing device is installed at the feed inlet of the box and is used to disperse the tea leaves fed into the uppermost mixing chamber.

[0014] The conveying device is installed outside the box and is positioned opposite the outlet of the lowest mixing chamber. The conveying device is used to receive and transport the tea leaves output from the lowest mixing chamber.

[0015] Further, the aforementioned dispersing device includes:

[0016] At least two fan blades are arranged in a ring, and the fan blades are rotated in the uppermost mixing chamber of the box and are opposite to the feed inlet.

[0017] A fan blade drive mechanism is located on the housing and is connected to at least two fan blades. The fan blade drive mechanism is used to drive at least two fan blades to rotate, so as to disperse the tea leaves entering the uppermost mixing chamber and make them evenly dispersed.

[0018] Furthermore, the aforementioned fan blades are inclined downwards toward the inner wall of the housing.

[0019] Furthermore, the cross-section of the aforementioned fan blade is arc-shaped, and the concave surface of the arc-shaped fan blade faces upward.

[0020] Furthermore, the aforementioned feeding device is provided in at least two units, and the number of dispersing devices and feed inlets is the same as the number of feeding devices, and they are set up in a one-to-one correspondence.

[0021] In a further configuration, the aforementioned partition assembly includes a partition, which is fixed inside the box and extends downward at an angle, forming a discharge port between the partition and the inner wall of the box.

[0022] In a further configuration, the aforementioned opening and closing device includes a closing plate and a closing plate driving assembly. The closing plate driving assembly is located inside the housing and is connected to the closing plate in a transmission manner. The closing plate driving assembly is used to drive the closing plate to flip between a first position and a second position.

[0023] When the closing plate is flipped to the first position, it abuts against the partition to close the discharge port; when the closing plate is flipped to the second position, the closing plate extends downward toward the partition to open the discharge port.

[0024] Further, the aforementioned partition is symmetrically arranged in two pieces, both of which extend downwards and tilt towards the middle of the box, forming a discharge port between the two partitions and the inner wall of the box;

[0025] Two symmetrical closing plates are provided. When the closing plate is flipped to the first position, one side of the closing plate abuts against the partition and the other side abuts against another closing plate to close the discharge port. When the closing plate is flipped to the second position, the two closing plates extend downwards towards the adjacent partition.

[0026] Further configuration: the aforementioned conveying device includes a conveyor belt mechanism and two baffles, which are respectively located on both sides of the conveyor belt mechanism.

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the tea leaf blending machine provided by this utility model has the following beneficial effects:

[0029] When using the tea uniform mixing machine provided by this utility model, the opening and closing device is initially in the default closed discharge port state. First, the feeding device conveys the tea leaves through the inlet to the uppermost mixing chamber. At the same time, the dispersing device efficiently disperses the tea leaves entering the uppermost mixing chamber, preventing them from piling up and creating favorable conditions for thorough mixing, greatly improving the uniformity of the mixture. After a period of conveying, when the preset amount of tea leaves is reached, the feeding device stops conveying tea leaves. Subsequently, the opening and closing device corresponding to the uppermost mixing chamber opens its discharge port, and the tea leaves in the uppermost mixing chamber fall smoothly and automatically into the next mixing chamber under the action of gravity. This process requires no manual intervention. The system automatically transfers tea leaves, improving production efficiency and reducing errors and contamination risks associated with manual operation. Then, the opening and closing device corresponding to the uppermost mixing chamber closes its outlet again, while the feeding device continues to deliver tea leaves, repeating the above process. Simultaneously, the opening and closing device corresponding to the lower mixing chamber opens its outlet, allowing all the tea leaves in that chamber to fall into the next lower mixing chamber, where the falling tea leaves further mix. This cycle continues until the opening and closing device corresponding to the bottommost mixing chamber opens its outlet, allowing all the tea leaves to fall onto the conveying device. Finally, the conveying device delivers the evenly mixed tea leaves to the next production equipment for further processing. It can be seen that this invention constructs an automated tea mixing and stacking system through the coordinated work of various devices. The dispersing device ensures even distribution of tea leaves in the initial stage, while at least two mixing chambers achieve multi-stage mixing, improving the uniformity of the tea mixture. The combination of these two elements effectively enhances the mixing effect of the tea leaves. Attached Figure Description

[0040] 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.

[0041] This invention provides a tea blending machine to solve the problem of how to improve the mixing effect of tea.

[0042] See Figure 1 and Figure 2 As shown, Figure 1 This is a three-dimensional view of the tea blending machine in the embodiment. Figure 2 The image shown is a three-dimensional view of the tea uniform stacking machine after it has been cut open in the embodiment. The tea uniform stacking machine includes a box body 1, an opening and closing device 2, a feeding device 3, a dispersing device 4, and a conveying device 5.

[0043] The housing 1 contains at least two partition assemblies 6. The at least two partition assemblies 6 are vertically spaced to divide the internal space of the housing 1 into at least two mixing chambers 7. The top of the housing 1 has a feed inlet 11 communicating with the uppermost mixing chamber 7. The partition assembly 6 has a discharge outlet 61.

[0044] The opening and closing device 2 is installed at the discharge port 61 of the box 1 and is used to control the opening and closing of the discharge port 61.

[0045] The feeding device 3 is installed outside the housing 1 and is connected to the feed inlet 11. The feeding device 3 is used to feed tea leaves into the feed inlet 11.

[0046] The dispersing device 4 is installed at the feed inlet 11 of the housing 1 and is used to disperse the tea leaves fed into the uppermost mixing chamber 7.

[0047] The conveying device 5 is installed outside the housing 1 and is positioned opposite the outlet 61 of the lowest mixing chamber 7. The conveying device 5 is used to receive and convey the tea leaves output from the lowest mixing chamber 7.

[0048] When using the tea uniform mixing machine described above, the opening and closing device 2 is initially in the default closed state of the discharge port 61. First, the feeding device 3 conveys the tea leaves through the inlet 11 to the uppermost mixing chamber 7. At the same time, the dispersing device 4 efficiently disperses the tea leaves in the uppermost mixing chamber 7, preventing them from piling up and creating favorable conditions for thorough mixing, greatly improving the uniformity of the mixture. After a period of conveying, when the preset amount of tea leaves is reached, the feeding device 3 stops conveying the tea leaves. Subsequently, the opening and closing device 2 corresponding to the uppermost mixing chamber 7 opens its discharge port 61, and the tea leaves in the uppermost mixing chamber 7 fall smoothly and automatically into the next mixing chamber 7 under the action of gravity. This process requires no manual intervention, realizing automatic transfer of tea leaves, which not only improves production efficiency but also reduces the error and contamination risks that may be caused by manual operation. Then, the opening and closing device 2 corresponding to the uppermost mixing chamber 7 closes its outlet 61 again, and the feeding device 3 continues to convey tea leaves, repeating the above operation process. At the same time, the opening and closing device 2 corresponding to the lower mixing chamber 7 opens its outlet 61, allowing all the tea leaves in that mixing chamber 7 to fall into the next lower mixing chamber 7. The falling tea leaves further mix through their movement, and this cycle repeats until the opening and closing device 2 corresponding to the lowermost mixing chamber 7 opens its outlet 61, allowing all the tea leaves inside to fall onto the conveying device 5. Finally, the conveying device 5 sends the evenly mixed tea leaves to the next production equipment for further processing. It can be seen that this utility model constructs an automated tea mixing and stacking system through the coordinated work of various devices. Among them, the dispersing device 4 ensures that the tea leaves are evenly distributed in the initial stage, while at least two mixing chambers 7 achieve multi-stage mixing of the tea leaves, improving the mixing uniformity of the tea leaves. The combination of the two can effectively improve the mixing effect of the tea leaves.

[0049] Furthermore, the discharge ports 61 of the two non-adjacent mixing chambers 7 of this invention can be opened simultaneously for falling and mixing operations. This design breaks the limitation of traditional layer-by-layer sequential discharge, greatly shortens the overall tea mixing time, significantly improves the overall efficiency of batch tea mixing, and meets the needs of large-scale tea production.

[0050] The aforementioned feeding device 3 can be used in conjunction with existing equipment such as lifting conveyors and conveyor belts to achieve feeding.

[0051] See Figure 2As shown, in one embodiment of the dispersing device 4, the dispersing device 4 includes fan blades 41 and a fan blade driving mechanism 42. The fan blades 41 are rotatably connected to the uppermost mixing chamber 7 of the housing 1 and are positioned opposite the feed inlet 11. There are at least two fan blades 41, arranged in a ring. The fan blade driving mechanism 42 is mounted on the housing 1 by welding or screwing and is drively connected to the at least two fan blades 41. The fan blade driving mechanism 42 drives the at least two fan blades 41 to rotate, thereby dispersing the tea leaves entering the uppermost mixing chamber 7 and distributing them evenly. Thus, the fan blades 41, driven by the fan blade driving mechanism 42, can powerfully disperse and evenly distribute the tea leaves entering the uppermost mixing chamber 7 from the feed inlet 11, effectively preventing the tea leaves from accumulating and allowing for a more even distribution of the tea leaves within the uppermost mixing chamber 7, thereby improving the subsequent mixing effect.

[0052] The aforementioned fan blade drive mechanism 42 can use an existing rotary motor or rotary drive mechanism 221, whose output end is connected to the fan blade 41 by welding or screwing.

[0053] See Figure 2 As shown, based on the above embodiment, the fan blades 41 are inclined downwards toward the inner wall of the housing 1. This inclined arrangement allows the fan blades 41 to not only disperse the tea leaves during rotation but also guide them toward the edge of the mixing chamber 7, thus improving the dispersion effect.

[0054] See Figure 2 As shown, based on the above embodiment, the cross-section of the fan blade 41 is arc-shaped, and the concave surface of the fan blade 41 faces upward. This arc-shaped fan blade 41 design with the concave surface facing upward allows for better guidance of the tea leaves towards the edge of the mixing chamber 7 during rotation, further enhancing the dispersion effect.

[0055] See Figure 1 As shown, based on any of the above embodiments, the number of feeding devices 3 is at least two. The number of dispersing devices 4 and feeding ports 11 is the same as the number of feeding devices 3, and they are arranged in a one-to-one correspondence. In this way, the arrangement of multiple feeding devices 3, dispersing devices 4, and feeding ports 11 can realize the simultaneous feeding and dispersing of multiple types of tea, meet the mixing needs of different tea varieties or different batches of tea, and improve the versatility and production efficiency of the equipment.

[0056] See Figure 2As shown, based on any of the above embodiments, the partition assembly 6 includes a partition 62. The partition 62 is fixed inside the housing 1 by welding or screwing. The partition 62 extends downward at an angle, forming a discharge port 61 between the partition 62 and the inner wall of the housing 1. In this way, the inclined partition 62 can guide the tea leaves to move automatically towards the discharge port 61 under the action of gravity, flow smoothly out of the discharge port 61, and further mix the tea leaves by moving towards the discharge port 61, thereby improving the mixing effect.

[0057] See Figure 2 As shown, in one embodiment of the opening and closing device 2, the device includes a closing plate 21 and a closing plate driving assembly 22. The closing plate driving assembly 22 is disposed inside the housing 1 and is drively connected to the closing plate 21. The closing plate driving assembly 22 is used to drive the closing plate 21 to rotate between a first position and a second position. When the closing plate 21 rotates to the first position, it abuts against the partition 62 to close the discharge port 61; when the closing plate 21 rotates to the second position, it extends downwards and tilts towards the partition 62 to open the discharge port 61. Thus, by driving the closing plate 21 to rotate through the closing plate driving assembly 22, flexible opening and closing control of the discharge port 61 is achieved. This is convenient to operate and allows for precise control of the tea discharge time and flow rate according to production needs, ensuring the stability of the mixing process and the consistency of product quality. In addition, the closed plate 21, which is inclined downward toward the partition 62, can guide the tea leaves at the outlet 61 to move automatically toward the partition 62 of the next mixing chamber 7 under the action of gravity. The inclined partition 62 of the next mixing chamber 7 then drives the tea leaves to move automatically toward the outlet 61 of the next mixing chamber 7 under the action of gravity. This repeated movement can further mix the tea leaves and greatly improve the mixing effect of the tea leaves.

[0058] The aforementioned closing plate drive assembly 22 can use an existing rotary motor or rotary cylinder, or other rotary drive mechanism 221, and be fixed to the housing 1 by means of screwing or welding, with its output end fixedly connected to the closing plate 21 by means of screwing or welding; or the aforementioned closing plate drive assembly 22 can use a telescopic mechanism 222, such as a telescopic cylinder or telescopic rod, and be rotatably connected to the housing 1, with its output end rotatably connected to the closing plate 21 through a crank-connecting rod mechanism 223. The former embodiment can directly rotate the closing plate 21, occupying less space, while the latter embodiment drives the closing plate 21 to rotate by telescopic movement, occupying more space.

[0059] If the aforementioned fan blade drive mechanism 42 and closing plate drive assembly 22, etc., are installed inside the housing 1, then a protective cover 8 needs to be welded or screwed into the housing 1. Figure 2 As shown, the drive unit is enclosed in the protective cover 8 to prevent tea leaves from accidentally falling into the drive unit, affecting its use, or even damaging it.

[0060] See Figure 2 As shown, based on the above embodiment, two partitions 62 are symmetrically distributed, and both partitions 62 extend downwards at an incline towards the center of the housing 1. A discharge port 61 is formed between the two partitions 62 and the inner wall of the housing 1. Two closing plates 21 are symmetrically distributed. When a closing plate 21 is flipped to the first position, one side of the closing plate 21 abuts against a partition 62, and the other side abuts against another closing plate 21, thus closing the discharge port 61. When a closing plate 21 is flipped to the second position, both closing plates 21 extend downwards at an incline towards the adjacent partition 62. In this way, the two symmetrical partitions 62 and the two symmetrical closing plates 21 simultaneously guide the movement of the tea leaves, which not only makes the tea leaves mix more evenly, thereby improving the mixing effect, but also increases the tea leaf discharge efficiency.

[0061] like Figure 2 As shown, in this embodiment, the bottommost mixing chamber 7 has one closing plate 21, and the closing plate driving assembly 22 uses the latter embodiment described above, while the other upper mixing chambers 7 have two closing plates 21, and the closing plate driving assembly 22 uses the former embodiment described above.

[0062] See Figure 1 and Figure 2 As shown, in one embodiment of the conveying device 5, the conveying device 5 includes a conveyor belt mechanism 51 and two baffles 52. The two baffles 52 are respectively disposed on both sides of the conveyor belt mechanism 51 by welding or screwing. In this way, the baffles 52 on both sides can effectively prevent the tea leaves from spilling out during the conveying process due to the downward tilting action of the closing plate 21 or other factors, ensuring that all the tea leaves are conveyed to the subsequent process, improving the utilization rate of tea leaves and production efficiency, while maintaining the cleanliness of the production site.

[0063] The aforementioned conveyor belt mechanism 51 can use an existing belt conveyor mechanism.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
