Description

Technical Field

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

[0002] Blending and mixing refers to the process of mixing semi-finished tea of ​​different specifications in a certain proportion and achieving uniform mixing through physical or mechanical means. It is a key process in the refining and processing of tea, and the tea mixing machine is the key equipment for achieving blending and mixing.

[0003] Existing technology discloses a tea blending and mixing machine, which includes a control box and a hinge assembly. The control box contains, from top to bottom, a tea dispenser, an upper control chamber, and a lower control chamber. A partition separates the upper and lower control chambers, with multiple louvered doors arranged sequentially on the partition. The hinge assembly is located within the upper control chamber and includes multiple hinges corresponding to the louvers. Each hinge is connected to its corresponding louvered door via a rotating belt to control the opening and closing of that door. Specifically, the tea dispenser sprinkles tea leaves into the upper control chamber. Subsequently, the hinges of the hinge assembly rotate synchronously to open the louvers, allowing the tea leaves to fall from the upper control chamber into the lower control chamber for further mixing.

[0004] However, on the one hand, the arrangement of hinges, rotating belts, and louvers in groups, with multiple hinges and rotating belts corresponding to each louver, increases the complexity of the structure. On the other hand, since the transmission processes between each group of hinges, rotating belts, and louvers are relatively independent, the synchronicity and consistency of the opening and closing actions of each louver may be affected, thus impacting the uniform mixing effect. Utility Model Content

[0005] The purpose of this utility model is to provide a vertical tea uniform mixing machine. The technical problem is: how to reduce structural complexity and how to enhance the mixing effect.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0007] This utility model provides a vertical tea leaf blending machine, comprising: a machine body with a feed inlet at the top and a discharge outlet at the bottom; the machine body having a layered structure that divides the interior of the machine body into an upper chamber and a lower chamber, and having several horizontally arranged discharge outlets that connect the upper chamber and the lower chamber, with the upper chamber connected to the feed inlet and the lower chamber connected to the discharge outlet; a tea-spreading mechanism including a tea-spreader rotatably disposed in the upper chamber and arranged directly below the feed inlet; and an opening and closing mechanism including doors, an active component, and a transmission component. The number of doors is the same as the number of discharge outlets, and each door corresponds one-to-one with each discharge outlet. Both the doors and the active component are movably connected to the machine body, and each door is connected to the active component via the transmission component, so that when the active component moves relative to the machine body, it moves relative to the machine body to open or close each discharge outlet.

[0008] In some embodiments of this application, both the door body and the driving member are rotatably connected to the machine body. The door body rotates relative to the machine body to open or close the material discharge port.

The first gear is rotatably connected to the machine body and has the driving gear teeth. The connecting seat is connected to the first gear and the driving component respectively. The door body includes a door panel, a rotating rod, and a second gear connected together. The door panel is used to open or close the material discharge port. The rotating rod is rotatably connected to the machine body, and one end of the rotating rod is provided with a second gear. The second gear is located outside the machine body and has the driven gear teeth.

[0010] In some embodiments of this application, the layered structure is wavy and has several downward-facing recessed positions, and the bottom of the recessed positions is provided with the material discharge port.

[0011] In some embodiments of this application, the lower chamber has a cross-section that is wider at the top and narrower at the bottom in the horizontal arrangement direction of each of the doors, and includes a constant diameter portion and a reduced diameter portion. The constant diameter portion is located above the reduced diameter portion and is connected to the discharge port and the flared end of the reduced diameter portion, respectively. The reduced diameter end of the reduced diameter portion forms the discharge port.

[0012] In some embodiments of this application, the vertical tea uniform stacker further includes a feeding mechanism and a discharging mechanism. The feeding mechanism is used to receive tea leaves and transport them to the inlet, while the discharging mechanism is used to receive tea leaves falling from the outlet and transport them to the outside.

[0013] In some embodiments of this application, the upper chamber is cylindrical or cubic, and there are several feed inlets, each feed inlet arranged radially in the cylindrical upper chamber or diagonally in the cubic upper chamber; the number of tea-sprinkling mechanisms is the same as the number of feed inlets, and the tea sprinkler of each tea-sprinkling mechanism corresponds one-to-one with each feed inlet.

[0014] In some embodiments of this application, there are two feed inlets, and the feeding mechanism includes a hoist, a horizontal conveyor, and a distributor. The hoist extends vertically, and there are two horizontal conveyors. The two horizontal conveyors extend in the same horizontal direction and are spaced apart in a direction perpendicular to their extension direction. The distributor is in the shape of an octagon and is located below the discharge end of the hoist. The two channels of the octagonal distributor are respectively arranged opposite to the two horizontal conveyors.

[0015] In some embodiments of this application, the tea-sprinkling mechanism further includes a support and a drive mechanism. The support is supported on the top surface of the machine body, and the drive mechanism is disposed on the support. The tea-sprinkler includes a rotating rod and a main body. One end of the rotating rod is rotatably connected to the support and is connected to the drive mechanism. The other end extends into the upper cavity and is connected to the main body. The main body is provided with a main groove and a plurality of channels arranged circumferentially around the main groove. The channels are provided with tea-sprinkling openings, which are located radially on the main groove.

[0016] In some embodiments of this application, some of the channels are long channels and the remaining channels are short channels, and in the radial direction of the main groove, the length of the long channel is greater than the length of the short channel; each of the long channels and each of the short channels are interspersed, and there is a short channel between two adjacent long channels and a long channel between two adjacent short channels.

[0017] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0018] In this embodiment of the vertical tea blending machine, tea leaves are fed into the inlet and fall onto the tea spreader. The tea spreader rotates, generating centrifugal force and scattering the tea leaves around the upper chamber. Subsequently, the driving component moves and drives the various gates to open the various discharge ports synchronously. At this time, the tea leaves in the upper chamber fall into the lower chamber through the various discharge ports and are discharged through the outlet, thus completing the blending of the tea leaves. Through the coordinated cooperation between the driving component, the transmission component, and the various gates, the "centralized drive + forced synchronization" method replaces the "independent drive + independent transmission" method in the prior art. On the one hand, it can effectively reduce the number of components, making the overall structure simpler and reducing structural complexity. On the other hand, the forced synchronization method improves the synchronicity and consistency of the opening and closing of the various gates, thereby enhancing the blending effect.

[0034] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0035] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0036] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0037] Please see Figures 1 to 3 , Figure 6 and Figure 7The vertical tea-spreading machine provided in one embodiment of this utility model mainly includes a machine body 1, a tea-spreading mechanism 2, and an opening and closing mechanism 3. The machine body 1 has a feed inlet 121 at the top and a discharge outlet 122 at the bottom. The machine body 1 has a layered structure 13, which divides the interior of the machine body 1 into an upper chamber 123 and a lower chamber 124. Several horizontally arranged discharge outlets 131 are provided, connecting the upper chamber 123 and the lower chamber 124. The upper chamber 123 connects to the feed inlet 121, and the lower chamber 124 connects to the discharge outlet 122. The tea-spreading mechanism 2 includes a tea-spreader 21, which is rotatably disposed within the upper chamber 123 and positioned directly below the feed inlet 121. The opening and closing mechanism 3 includes a door body 31, an active component 32, and a transmission component 33. The number of door bodies 31 is the same as the number of material discharge ports 131, and each door body 31 corresponds to each material discharge port 131. Both the door body 31 and the active component 32 are movably connected to the machine body 1. Each door body 31 is connected to the active component 32 through the transmission component 33, so that when the active component 32 moves relative to the machine body 1, it moves relative to the machine body 1 and opens or closes each material discharge port 131.

[0038] In the vertical tea uniform mixing machine of this embodiment, tea leaves are fed into the feed inlet 121 and fall onto the tea spreader 21. The tea spreader 21 rotates, generating centrifugal force and scattering the tea leaves around the upper chamber 123. Subsequently, the driving component 32 moves and drives the various gates 31 to open the various discharge ports 131 synchronously through the transmission component 33. At this time, the tea leaves in the upper chamber 123 fall into the lower chamber 124 through the various discharge ports 131 and are discharged through the discharge port 122, thereby completing the uniform mixing of the tea leaves. Through the coordinated cooperation between the driving component 32, the transmission component 33, and the various gates 31, the "centralized drive + forced synchronization" method replaces the "independent drive + independent transmission" in the prior art. On the one hand, it can effectively reduce the use of components, making the overall structure simpler and thus reducing structural complexity. On the other hand, it improves the synchronicity and consistency of the opening and closing of the various gates 31, thereby enhancing the uniform mixing effect.

[0039] It is conceivable that the opening and closing mechanism 3 can control the flow rate and speed of the falling tea leaves, making it easier to adjust the uniform piling process.

[0040] It should be noted that both the door body 31 and the driving component 32 are movably connected to the body 1. This can be either a rotatable connection between the door body 31 and the driving component 32 and the body 1, a movable connection between the door body 31 and the driving component 32 and the body 1, or a rotatable connection between one of the door body 31 and the driving component 32 and the movable connection between the other and the body 1.

[0041] Please see Figure 2 , Figure 4 and Figure 5In one embodiment, where both the gate body 31 and the driving member 32 are movably connected to the machine body 1, and each gate body 31 is connected to the driving member 32 via a transmission member 33, both the gate body 31 and the driving member 32 are rotatably connected to the machine body 1. The gate body 31 rotates relative to the machine body 1 to open or close the material discharge port 131. The driving member 32 has a driving gear tooth 3211 located in the horizontal arrangement direction of each gate body 31. The gate body 31 is provided with a driven gear tooth 3131. The transmission member 33 is provided with teeth 331 extending along the horizontal arrangement direction of each gate body 31, and the teeth 331 mesh with the driving gear tooth 3211 of the driving member 32 and the driven gear tooth 3131 of each gate body 31. When the driving member 32 rotates, the driving gear 3211 rotates and drives the transmission member 33 to move horizontally. The horizontal movement of the transmission member 33 has the tendency to drive the driven gear 3131 of each door body 31 to rotate, thereby converting the rotation of the driving member 32 into the synchronous rotation of each door body 31. It is relatively simple in structure and arrangement, and stable and reliable.

[0042] In the embodiment where the driving member 32 is rotatably connected to the body 1 and the door 31 is movably connected to the body 1, the opening and closing mechanism 3 is arranged as described in the above embodiment. Each door 31 is movably connected to the body 1 through the cooperation of the slide block and guide rail, and each has a mating tooth corresponding to the transmission member 33. When the driving member 32 rotates, the driving gear tooth 3211 rotates and drives the transmission member 33 to move horizontally. Through the meshing between the tooth 331 and the mating part, the horizontal movement of the transmission member 33 has a tendency to drive each door 31 to move horizontally. Specifically, each door 31 can be accommodated below the layered structure 13 when moving horizontally.

[0043] In this embodiment, the transmission component 33 is a long rack.

[0044] In a specific embodiment, the driving component 32 includes a first gear 321, a connecting seat 322, and a driving component 323 located outside the machine body 1. The first gear 321 is rotatably connected to the machine body 1 and has a driving gear tooth 3211. The connecting seat 322 is connected to the first gear 321 and the driving component 323 respectively. The door body 31 includes a door panel 311, a rotating rod 312, and a second gear 313 connected together. The door panel 311 is used to open or close the material discharge port 131. The rotating rod 312 is rotatably connected to the machine body 1, and one end of it is provided with a second gear 313. The second gear 313 is located outside the machine body 1 and has a driven gear tooth 3131. Since the first gear 321, connecting seat 322, driving component 323, and second gear 313 are located outside the machine body 1, the key parts of the coordinated transmission between the door body 31 and the driving component 32 are prevented from being disturbed by tea leaves, thus ensuring the continuity and reliability of the transmission. Furthermore, by observing the positions of the first gear 321 and the second gear 313 on the transmission component 33, the opening and closing state of the door body 31 can be roughly determined. In this embodiment, the driving component 323 is an electric cylinder.

[0045] In other embodiments, the drive element 323 may be replaced with a handle.

[0046] It is conceivable that the connection between the rotating rod 312 and the door panel 311 in the above embodiment can be that one end of the rotating rod 312 located inside the body 1 is connected to the door panel 311, or that the outer peripheral surface of the rotating rod 312 is connected to the door panel 311.

[0047] Please see Figure 2 , Figure 6 and Figure 7 In a specific embodiment, the layered structure 13 has a wavy structure and forms several downward-facing recessed positions, with a discharge port 131 at the bottom of each recessed position. The tea leaves scattered by the tea sprinkler 21 will slide down the slope of the wavy structure into each recessed position, and slide downward when the door 31 opens the discharge port 131, increasing the length of the tea leaf flow path and reducing the amount of tea leaves remaining around the discharge port 131, thereby further improving the uniform mixing effect.

[0048] In a specific embodiment, the lower chamber 124 has a cross-section that is wider at the top and narrower at the bottom in the horizontal arrangement direction of each door 31, and includes a constant diameter portion 1241 and a narrowed diameter portion 1242. The constant diameter portion 1241 is located above the narrowed diameter portion 1242 and is connected to the discharge port 131 and the flared end of the narrowed diameter portion 1242, respectively. The narrowed end of the narrowed diameter portion 1242 forms the discharge port 122. The upper-wide and lower-narrow structural design of the lower chamber 124 allows the tea leaves to gradually concentrate during the falling process, making it easier to control the discharge speed and discharge volume. The tea leaves in the lower chamber 124 will slide down the slope of the narrowed diameter portion 1242 and finally flow out from the discharge port 122. The cross-sectional shape design of the lower chamber 124 can promote the flow of tea leaves and improve the mixing uniformity.

[0049] In this embodiment, the vertical tea uniform stacker also includes a door structure for opening and closing the discharge port 122, and the door structure can be arranged with reference to the door body 31 in the above embodiments.

[0050] Please see Figures 1 to 3 , Figure 6 and Figure 7 In a specific embodiment, the vertical tea blending machine further includes a feeding mechanism 4 and a discharging mechanism 5. The feeding mechanism 4 is used to receive tea leaves and transport them to the inlet 121, while the discharging mechanism 5 is used to receive tea leaves falling from the outlet 122 and transport them to the outside. The arrangement of the feeding mechanism 4 and the discharging mechanism 5 allows the vertical tea blending machine to be embedded in an automated tea production line, wherein the feeding mechanism 4 is used to receive the tea leaves output after the previous process is completed, and the discharging mechanism 5 is used to output the blended tea leaves to the next process.

[0051] Please see Figures 1 to 3In a specific embodiment, the upper chamber 123 is cylindrical or cubic, and several feed inlets 121 are provided. Each feed inlet 121 is arranged radially along the upper chamber 123 or diagonally along the upper chamber 123. The number of tea-spreading mechanisms 2 is the same as the number of feed inlets 121, and each tea-spreading device 21 of the tea-spreading mechanism 2 corresponds one-to-one with each feed inlet 121. In traditional single-feed-inlet 121 designs, the feed inlet 121 is usually located in the center. Under the centrifugal force of the tea-spreading device 21, the tea leaves mainly accumulate at the edges of the upper chamber 123, with the tea leaves in the center being relatively sparse. The arrangement in this embodiment allows tea leaves to be conveyed into the chamber from different positions, increasing the dispersion range of the tea leaves entering the chamber and further improving the dispersion degree of the tea leaves in the upper chamber 123, which is beneficial for uniform stacking. On the other hand, the multiple discharge ports 122 can also accommodate multiple tea leaf inputs, thereby improving production efficiency.

[0052] In a specific embodiment, there are two feed inlets 121. The feeding mechanism 4 includes a hoist 41, a conveyor 42, and a distributor 43. The hoist 41 extends vertically, and there are two conveyors 42. The two conveyors 42 extend in the same horizontal direction and are arranged at intervals in a direction perpendicular to their extension direction. The distributor 43 is in the shape of an octagon and is located below the discharge end of the hoist 41. The two channels 2122 of the octagonal distributor 43 are respectively arranged opposite to the two conveyors 42.

[0053] Through the coordinated operation of the elevator 41, the horizontal conveyor 42, and the distributor 43, the tea leaves can be centrally lifted and distributed, and transported to different feed inlets 121. Specifically, the elevator 41 is used to lift the tea leaves on the ground to the top of the machine body 1, the distributor 43 is used to guide the tea leaves output by the elevator 41 into the two horizontal conveyors 42, and the horizontal conveyors 42 are used to transport the tea leaves to the feed inlets 121. Compared with the method of setting two feeding mechanisms 4 at the same time, the redundant structure is combined, thereby reducing the cost of component use.

[0054] Please see Figure 8 In a specific embodiment, the tea-sprinkling mechanism 2 further includes a support 22 and a drive mechanism 23. The support 22 is supported on the top surface of the body 1, and the drive mechanism 23 is mounted on the support 22. The tea-sprinkler 21 includes a rotating rod 211 and a main body 212. One end of the rotating rod 211 is rotatably connected to the support 22 and is connected to the drive mechanism 23. The other end extends into the upper chamber 123 and is connected to the main body 212. The main body 212 is provided with a main groove 2121 and several channels 2122 arranged circumferentially around the main groove 2121. The channels 2122 are provided with tea-sprinkling nozzles 2123, which are located radially on the main groove 2121.

[0055] The main trough 2121 is located at the center of the main body 212 and is mainly used to receive the tea leaves falling from the feed inlet 121. Under the action of centrifugal force, the tea leaves enter the channel 2122 from the main trough 2121 and are sprayed out from the tea sprinkling port 2123 of the channel 2122. The arrangement of the tea sprinkling mechanism 2 can improve the uniformity of tea leaf sprinkling, thereby further improving the uniform mixing effect.

[0056] In this embodiment, the drive mechanism 23 includes a motor and a reducer connected together, and the output end of the reducer and one end of the rotating rod 211 are connected by a gear combination transmission.

[0057] In a specific embodiment, some channels 2122 are long channels, and the remaining channels 2122 are short channels. In the radial direction of the main channel 2121, the length of the long channels is greater than the length of the short channels. The long channels and the short channels are arranged in an interleaved manner, with a short channel between two adjacent long channels and a long channel between two adjacent short channels.

[0058] During the rotation of the tea sprinkler 21, due to the different lengths of the long and short channels, the movement trajectory and spreading range of the tea leaves entering the long and short channels from the main groove 2121 will differ. Specifically, the long channel causes the tea leaves to be spread a relatively longer distance and form a larger circle, while the short channel causes the tea leaves to be spread a relatively shorter distance and form a smaller circle, thus creating different layers of tea-spreading effect. The interlacing arrangement of the long and short channels achieves multi-layered tea-spreading, further enriching the distribution of the tea leaves and making the spatial distribution of the tea leaves more uniform, thereby improving the quality and effect of the even distribution.

[0059] It should be noted that by controlling the rotation speed of the drive mechanism 23, the magnitude of the centrifugal force generated by the rotation of the tea sprinkler 21 can be controlled, thereby adjusting the size of the circles of tea sprinkled from the long channel and the short channel respectively.

[0060] Please see Figure 1 , Figure 2 and Figure 5 In a specific embodiment, the machine body 1 includes a frame 11 and a chamber 12 mounted on the frame 11. The chamber 12 has an inlet 121 and an outlet 122. A layered structure 13 is provided inside the chamber 12, dividing the interior of the chamber 12 into an upper chamber 123 and a lower chamber 124. The door 31 and the driving component 32 are both movably connected to the chamber 12. The frame 11 provides rigid support, and the chamber 12, as the main functional carrier of the machine body 1, ensures the stability and reliability of the overall structure.

[0061] Please see Figure 5In a further embodiment, both the material inlet 131 and the material outlet 122 extend from one horizontal side of the bin body 12 to the other horizontal side of the bin body 12. In this embodiment, the two ends of the rotating rod 312 are rotatably connected to the two horizontal sides of the bin body 12, and one end connected to the second gear 313 extends out of the bin body 12, while the other end can extend out of the bin body 12 or be located inside the bin body 12.

[0062] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
