Description

Technical Field

[0001] The invention belongs to the technical field of tea drying devices, and in particular refers to a tea drying device capable of automatically controlling time. Background Art

[0002] Tea drying machines generally adopt a horizontal layout, stirring and frying through a rotating drum, with materials fed in at one end and discharged at the other end. Since this type of machine generally stirs the material through forward rotation and discharges the material through reverse rotation, an inclined baffle is generally set inside the drum. This baffle can be spiral and continuous, or multi-stage and independent.

[0003] This structure is generally believed to be an improvement on a concrete mixer, and can automatically load and unload materials through the forward and reverse rotation of the motor. However, there is a significant difference in fluidity between solid bulk materials such as tea leaves and cement concrete. Although the tea leaves can be stir-fried by reverse rotation, the continuous, unidirectional lateral force they are subjected to will cause them to accumulate at one end, which contradicts the principle of spreading the tea leaves as evenly as possible during the drying process.

[0004] How to prevent the solid bulk materials from piling up on one side on the basis of forward and reverse control of loading and unloading is the primary problem to be solved by the present invention.

[0005] In addition, general drying devices set the drying time in advance, but the moisture content of the input materials is not constant. Therefore, if it is possible to determine whether the drying is completed by detecting the current moisture content, it will be the most accurate and energy-saving solution. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a tea drying device that can control the loading and unloading of materials by forward and reverse rotation and avoid the accumulation of materials toward one end during the stirring process; on the basis of the traditional stirring device, this scheme adds a variable inclined plate that can change direction, and the driving force when the polygonal drum is driven by the motor to rotate is linked with the double ball head connecting rod to adjust the direction of the variable inclined plate. In the stirring state, the fixed inclined plate and the variable inclined plate are in opposite directions, so that the material is fully stirred and spread; in the unloading state, the fixed inclined plate and the variable inclined plate are in the same direction, and both can push the material inside the polygonal drum toward the end where the discharge baffle is located.

[0007] In addition, the present invention also detects the humidity of the reflux gas or the inside of the material by means of a humidity monitoring probe arranged inside or outside the recovery pipe, thereby controlling the start and stop of the drying device and automatic unloading of the material.

[0008] The technical solution adopted by the present invention is as follows: The present invention proposes a tea drying device capable of automatically controlling time, comprising a rolling, mixing and stir-frying mechanism, a guide plate automatic reversing mechanism, a feeding assembly, and an induction drying mechanism, wherein the feeding assembly and the induction drying mechanism are respectively arranged at both ends of the rolling, mixing and stir-frying mechanism; the guide plate automatic reversing mechanism is arranged in the rolling, mixing and stir-frying mechanism.

[0009] Furthermore, the rolling mixing and frying mechanism comprises a supporting assembly, a rotating assembly and a driving assembly, wherein the rotating assembly is rotatably arranged in the supporting assembly, and the driving assembly is arranged in the supporting assembly, and the rotating assembly can be rotated by the driving assembly; Through the rotation of the rotating component, on the one hand, the lateral movement of the material can be controlled to control the feeding and unloading of the material; on the other hand, the material can be mixed and stir-fried during the rotation process, so that the drying process of the material in each part can be more uniform.

[0010] Among them, the support assembly includes an outer shell, a support frame, a support roller, a limit shaft and a limit roller, the support frame is symmetrically arranged inside the outer shell, the support roller is rotatably arranged on the top of the support frame, the limit shaft is fixedly connected to the inner wall of the outer shell, and the limit roller is rotatably arranged on the limit shaft.

[0011] Preferably, the rotating assembly comprises a polygonal roller and a conical bucket, the polygonal roller consists of a flat plate portion uniformly distributed in an annular shape and an annular portion at both ends, the conical bucket is arranged in the annular portion at one end, and the annular portion is in rolling contact with the supporting roller and the limiting roller respectively.

[0012] As a further preferred embodiment of the present invention, the driving assembly includes a driving motor, a driving gear and a driven gear. The driving motor is arranged on the inner wall of the outer shell, the driving gear is engaged with the output shaft of the driving motor, the driven gear is arranged on the rotation limiting assembly, the driven gear and the annular portion are coaxially arranged, and the driven gear and the driving gear are meshed for transmission.

[0013] The support and limitation of the support roller and the limiting roller can keep the central axis position of the polygonal drum unchanged, and the driving of the driving motor and the driving gear can drive the polygonal drum to rotate in two directions.

[0014] Furthermore, the guide plate automatic reversing mechanism includes a rotation limit assembly, a guide inclined plate assembly and an inclined plate reversing assembly, the rotation limit assembly is rotatably arranged on the rotating assembly, the guide inclined plate assembly is evenly distributed in an annular manner on the rotating assembly, and the inclined plate reversing assembly is arranged between the rotation limit assembly and the guide inclined plate assembly.

[0015] Through the linkage structure design of the guide plate automatic reversing mechanism, when the driving motor switches between forward and reverse rotation, the direction of the variable inclined plate can be switched first, which can prevent the material from being transported and accumulated in one direction during forward rotation and improve the stirring and mixing effect; it can also promote the stable discharge of the material during reverse rotation.

[0016] Preferably, the rotation limit assembly includes a rotating ring, a limit block and a first ball joint seat, the rotating ring is rotatably arranged on the circular ring portion, the driven gear is arranged on the rotating ring and is coaxially arranged with the rotating ring, the rotating ring is provided with boss portions evenly distributed in an annular shape, the first ball joint seat is arranged on the boss portion, the rotating ring is also provided with groove portions evenly distributed in an annular shape, the rotating ring is fixedly connected to the circular ring portion, and the limit block is slidably arranged in the groove portion.

[0017] Due to the limitation of the limit block, the rotating collar and the circular ring part can only produce relative rotation within a certain range. This relative rotation angle just corresponds to the movement amplitude required for the variable inclined plate to flip. When the driving motor changes the rotation direction, it will first rotate the rotating collar through the driven gear. At this time, through the linkage of the double ball head connecting rod, the linkage rod and the rotating shaft can move relative to each other.

[0022] The drying device adopts a model with waste heat recycling, which can significantly reduce energy consumption on the one hand, and on the other hand, it can judge the current drying progress by the humidity of the return air, thereby achieving the technical effect of automatic shutdown after drying is completed.

[0023] Furthermore, the feed assembly includes a feed bracket, a feed funnel and a discharge baffle, the feed bracket is arranged on the outer shell, the feed funnel is arranged on the feed bracket, the end of the feed funnel is located in the conical hopper, and the discharge baffle is detachably arranged at one end of the outer shell close to the induction drying mechanism.

[0024] The beneficial effects achieved by the present invention using the above structure are as follows: (1) Through the rotation of the rotating component, on the one hand, the lateral movement of the material can be controlled to control the feeding and unloading of the material; on the other hand, the material can be mixed and stir-fried during the rotation process, so that the drying process of the material in each part is more uniform.

[0025] (2) Through the support and limitation of the support roller and the limiting roller, the central axis position of the polygonal roller can be kept unchanged, and through the drive of the driving motor and the driving gear, the polygonal roller can be driven to rotate in two directions.

[0026] (3) Through the linkage structure design of the guide plate automatic reversing mechanism, when the drive motor switches between forward and reverse rotation, the direction of the variable inclined plate can be switched first, which can not only prevent the material from being transported and accumulated in one direction during forward rotation and improve the stirring and mixing effect; but also promote the stable discharge of the material during reverse rotation.

[0027] (4) Due to the limitation of the limit block, the rotating collar and the circular ring can only produce relative rotation within a certain range. This relative rotation angle just corresponds to the movement amplitude required for the variable inclined plate to flip. When the driving motor changes the rotation direction, it will first rotate the rotating collar through the driven gear. At this time, through the linkage of the double ball head connecting rod, the linkage rod and the rotating shaft can move relative to each other.

[0035] like Figure 1 to Figure 12 As shown, the present invention proposes a tea drying device 39 capable of automatically controlling time, comprising a rolling, mixing and frying mechanism 1, a guide plate automatic reversing mechanism 2, a feeding assembly 3, and an inductive drying mechanism 4, wherein the feeding assembly 3 and the inductive drying mechanism 4 are respectively arranged at both ends of the rolling, mixing and frying mechanism 1; the guide plate automatic reversing mechanism 2 is arranged in the rolling, mixing and frying mechanism 1; The rolling mixing and frying mechanism 1 comprises a supporting assembly 5, a rotating assembly 6 and a driving assembly 7. The rotating assembly 6 is rotatably arranged in the supporting assembly 5, and the driving assembly 7 is arranged in the supporting assembly 5. The rotating assembly 6 can be rotated by the driving assembly 7. Through the rotation of the rotating component 6, on the one hand, the lateral movement of the material can be controlled to control the feeding and unloading of the material; on the other hand, the material can be mixed and stir-fried during the rotation process, so that the drying process of the material in each part is more uniform.

[0036] The support assembly 5 includes an outer shell 8, a support frame 9, a support roller 10, a limit shaft 11 and a limit roller 12. The support frame 9 is symmetrically arranged inside the outer shell 8, the support roller 10 is rotatably arranged on the top of the support frame 9, the limit shaft 11 is fixedly connected to the inner wall of the outer shell 8, and the limit roller 12 is rotatably arranged on the limit shaft 11.

[0037] The rotating assembly 6 includes a polygonal roller 13 and a conical bucket 14. The polygonal roller 13 is composed of a flat plate portion 18 uniformly distributed in an annular shape and an annular portion 19 at both ends. The conical bucket 14 is arranged in the annular portion 19 at one end, and the annular portion 19 is in rolling contact with the supporting roller 10 and the limiting roller 12 respectively.

[0038] The driving assembly 7 includes a driving motor 15, a driving gear 16 and a driven gear 17. The driving motor 15 is arranged on the inner wall of the outer shell 8. The driving gear 16 is engaged with the output shaft of the driving motor 15. The driven gear 17 is arranged on the rotation limiting assembly 20. The driven gear 17 and the annular portion 19 are coaxially arranged, and the driven gear 17 and the driving gear 16 are meshed for transmission.

[0039] The support and limitation of the support roller 10 and the limiting roller 12 can keep the central axis position of the polygonal drum 13 unchanged, and the driving motor 15 and the driving gear 16 can drive the polygonal drum 13 to rotate in two directions.

[0040] The feed assembly 3 includes a feed bracket 36, a feed funnel 37 and a discharge baffle 38. The feed bracket 36 is arranged on the outer shell 8, the feed funnel 37 is arranged on the feed bracket 36, the end of the feed funnel 37 is located in the conical bucket 14, and the discharge baffle 38 is detachably arranged at one end of the outer shell 8 close to the induction drying mechanism 4.

[0041] The inductive drying mechanism 4 includes a drying device 39, a recovery pipe 40, an external pipe 41 and a humidity monitoring probe 42. The drying device 39 is arranged on the outer shell 8 through a bracket. The recovery pipe 40 and the external pipe 41 are arranged on the drying device 39. The recovery pipe 40 and the external pipe 41 are both located in the polygonal drum 13. The external pipe 41 is sleeved on the outside of the recovery pipe 40. The end of the recovery pipe 40 is provided with a flared portion 43. The humidity monitoring probe 42 is arranged in the recovery pipe 40.

[0042] The drying device 39 adopts a model with waste heat recycling, which can greatly reduce energy consumption on the one hand, and on the other hand can judge the current drying progress by the humidity of the return air, thereby achieving the technical effect of automatic shutdown after drying is completed.

[0043] The guide plate automatic reversing mechanism 2 includes a rotation limit assembly 20, a guide inclined plate assembly 21 and an inclined plate reversing assembly 22. The rotation limit assembly 20 is rotatably arranged on the rotating assembly 6, the guide inclined plate assembly 21 is evenly distributed in an annular shape on the rotating assembly 6, and the inclined plate reversing assembly 22 is arranged between the rotation limit assembly 20 and the guide inclined plate assembly 21.

[0044] Through the linkage structure design of the guide plate automatic reversing mechanism 2, when the driving motor 15 is switched between forward and reverse rotation, the direction of the variable inclined plate 28 can be switched first, which can prevent the material from being transported and accumulated in one direction during forward rotation and improve the stirring and mixing effect; it can also promote the stable discharge of the material during reverse rotation.

[0045] The rotation limit assembly 20 includes a rotating collar 23, a limit block 24 and a first ball joint seat 25. The rotating collar 23 is rotatably arranged on the annular portion 19. The driven gear 17 is arranged on the rotating collar 23 and is coaxially arranged with the rotating collar 23. The rotating collar 23 is provided with boss portions 32 in an annular manner. The first ball joint seat 25 is arranged on the boss portion 32. The rotating collar 23 is also provided with groove portions 33 in an annular manner. The rotating collar 23 is fixedly connected to the annular portion 19, and the limit block 24 is slidably arranged in the groove portion 33.

[0046] Due to the limitation of the limit block 24, the rotating collar 23 and the annular portion 19 can only produce relative rotation within a certain range, and this relative rotation angle just corresponds to the movement amplitude required for the variable inclined plate 28 to flip; when the driving motor 15 changes the rotation direction, it will first rotate the rotating collar 23 through the driven gear 17. At this time, through the linkage of the double ball head connecting rod 31, the linkage rod 29 and the rotating shaft 27 can make relative movement.

[0047] The guide inclined plate assembly 21 includes a fixed inclined plate 26, a rotating shaft 27 and a variable inclined plate 28. The fixed inclined plate 26 is arranged in an array inside the flat plate portion 18. The rotating shaft 27 is rotatably arranged on the flat plate portion 18. The variable inclined plate 28 is fixed to the rotating shaft 27. The variable inclined plate 28 and the fixed inclined plate 26 are arranged alternately. The rotating shaft 27 is provided with a rotating support rod 34 outside the flat plate portion 18, and the end of the rotating support rod 34 is provided with an end rotating shaft 35.

[0048] Since each group of rotating support rods 34 in the same row is mounted on the same linkage rod 29 , the same rotating support rod 34 can be turned over synchronously, and the direction of the variable inclined plate 28 can be adjusted through the movement of the linkage rod 29 .

[0049] The inclined plate reversing assembly 22 includes a linkage rod 29, a second ball joint seat 30 and a double ball head connecting rod 31. The end shaft 35 is rotatably arranged in the linkage rod 29. The second ball joint seat 30 is arranged at the end of the linkage rod 29. The double ball head connecting rod 31 is hinged to the second ball joint seat 30 and the first ball joint seat 25 through the ball heads at both ends.

[0050] like Fig.13 As shown, (a) represents the relative position of the fixed inclined plate 26 and the variable inclined plate 28 during the stirring process. At this time, the fixed inclined plate 26 and the variable inclined plate 28 are in opposite directions. By setting up a plurality of rows evenly distributed in an annular shape, the tea leaves can be randomly subjected to driving forces in two directions during the tumbling process, which can not only ensure that the material is evenly spread, but also avoid accumulation toward one end; (b) represents the relative position of the fixed inclined plate 26 and the variable inclined plate 28 during the unloading process. At this time, the fixed inclined plate 26 and the variable inclined plate 28 are in the same direction. Through the rotation of the polygonal drum 13, the fixed inclined plate 26 and the variable inclined plate 28 will exert a lateral thrust toward the discharge baffle 38 on the material, thereby allowing the material to leave the polygonal drum 13.

[0051] When in use, the user first needs to drive the driving motor 15 to rotate in the forward direction. Through the meshing transmission of the driving gear 16 and the driven gear 17, the rotating collar 23 first rotates relative to the annular portion 19 to a position against the limit block 24, and then rotates with the polygonal drum 13. At this time, the fixed inclined plate 26 and the variable inclined plate 28 are inclined in opposite directions. Then open the top cover of the feed hopper 37, add the material to be dried into the feed hopper 37, and the material enters the polygonal drum 13 along the feed hopper 37 and the conical hopper 14; the feed hopper 37 is located in the conical hopper 14, the feed hopper 37 and the conical hopper 14 do not contact but the gap is small, and the gas flows slowly; Since the fixed inclined plate 26 and the variable inclined plate 28 are in opposite directions, when the polygonal drum 13 rotates, the material will be located at the bottom of the polygonal drum 13 due to gravity; the material will be randomly subjected to lateral forces in the left and right directions, and under the action of this force, the material can be evenly spread in the horizontal direction; and the degree of mixing in this stirring mode is greater than that in the case of only the fixed inclined plate 26.

[0052] Embodiment 1: During the rotation of the polygonal drum 13, the drying device 39 is started, and the hot air enters the interior of the polygonal drum 13 through the interlayer between the recovery pipe 40 and the external pipe 41 to dry the material in the polygonal drum 13. At the same time, the gas can be refluxed through the recovery pipe 40. Since the external pipe 41 is located at one end of the polygonal drum 13 and the flared portion 43 is located at the other end of the polygonal drum 13, the dry hot air flow can remove moisture from the material by flowing horizontally in the polygonal drum 13. The humidity of the return air can be detected by the humidity monitoring probe 42, thereby reflecting the current drying progress.

[0053] Embodiment 2: The humidity monitoring probe 42 may also be located outside the recovery pipe 40 and extend into the material below through a long probe, but the position needs to be selected at a position that is not collided by the fixed inclined plate 26 and the variable inclined plate 28 .

[0054] Embodiment 3: When the moisture content detected by the humidity monitoring probe 42 is lower than a certain level, the drive motor 15 is turned off; after the discharge baffle 38 is opened automatically or manually, the drive motor 15 is started in reverse, and at this time, through the transmission of the driving gear 16 and the driven gear 17, the rotating collar 23 first rotates relative to the annular portion 19 until the limit block 24 abuts against the other end of the groove portion 33; During this process, through the linkage of the double ball head connecting rod 31, the linkage rod 29 will rotate with the rotating shaft 27, and at the same time, the variable inclined plate 28 will flip to the same direction as the fixed inclined plate 26; Subsequently, as the polygonal drum 13 rotates along with the rotating sleeve 23, the variable inclined plate 28 in the same direction as the fixed inclined plate 26 will, together with the fixed inclined plate 26, push the material inside the polygonal drum 13 laterally toward the end where the discharge baffle 38 is located; when the discharge baffle 38 is opened, the discharge can be completed.

[0055] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0056] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
