Description

Technical Field

[0001] This invention relates to the field of sesame oil making equipment technology, and more specifically to a sesame oil pressing machine. Background Technology

[0002] In the production of sesame oil, in order to increase the oil yield of sesame seeds and make the production process cleaner, three production processes must be carried out: stirring the oil, pressing the oil, and shaking the oil.

[0003] Traditional oil-coating processes often employ manual operation of oil hoists for vibration, but this method has significant limitations: on the one hand, the intensity and frequency of manual vibration are difficult to control precisely, which can easily lead to more uniform particle dispersion or oil emulsification due to improper operation, thus affecting the coagulation effect; on the other hand, manual operation cannot achieve automated continuous operation, resulting in low efficiency and difficulty in flexibly adjusting the mode of action according to the needs of different stages of oil coating.

[0004] In addition, some existing mechanized oil-pressing equipment has limited functionality. It can only achieve stirring and crushing, and cannot switch to a gentle vibration mode after the particles have agglomerated, which can easily damage the already formed large particle clusters. Alternatively, it cannot adjust the vibration rate without affecting the rotation speed of the oil pan, making it difficult to adapt to the needs of different oil and sauce states and oil-pressing stages. Summary of the Invention

[0016] The beneficial effects of this invention compared to the prior art are: 1. In the initial stage of processing, the downward movement of the lifting plate causes multiple irregular plates to split into independent stirring blades. By utilizing the dispersing and cutting effect of multiple blades, the suspension balance of particles in the oil sauce can be quickly broken, accelerating the collision and aggregation between small particles, and significantly shortening the formation cycle of large particle clusters. Compared with a single stirring mode, this improves the oil-forming efficiency. When the particles aggregate to the target shape, the lifting plate moves upward and drives the irregular plates to splice together into an oil-forming gourd structure. At this time, high-frequency vibration from top to bottom replaces rigid stirring. This not only further promotes the attachment of unaggregated small particles to large particle clusters through vibration energy, but also avoids the large particle clusters from breaking due to mechanical impact by using the flexible contact of the curved surface.

[0017] 2. In the initial stage of processing, the radius of the telescopic wheel is at its shortest distance, at which point the vibration frequency is highest. This, combined with the stirring blades formed by multiple irregular plates, quickly disperses stubborn aggregates of particles in the sauce. When the particles begin to initially agglomerate, the radius of the telescopic wheel is increased for the first time, and the vibration frequency is reduced. Medium-intensity vibration promotes the orderly binding of particles. Near the end of processing, the radius of the telescopic wheel is increased for the second time. Low-intensity vibration consolidates the structure of large particle clusters. The dynamic adjustment capability adapts to the entire process of sauce thickening and particle aggregation. Furthermore, the telescopic wheel allows for adjustment of the vibration frequency by changing the rotation speed of the oil pan, preventing the sauce from splashing and wasting due to excessive rotation speed.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given herein with reference to the accompanying drawings is for better explanation. The structure of the present invention necessarily exceeds the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail herein, but still fall within the protection scope of this application.

[0021] Figures 1-12 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figures 1-12 The present invention will be further described below.

[0022] A sesame oil pressing machine includes a base 1 and two oil pots 2. The two oil pots 2 are movably mounted above the base 1 via a support mechanism. A frame 4 is fixedly installed on the top of the base 1. An upper rotating shaft 3, a transmission shaft 12, and a lower rotating shaft 13 are rotatably mounted on the frame 4. Two L-shaped support plates 22 are fixedly installed on the frame 4. The transmission shaft 12 and the lower rotating shaft 13 are connected via a transmission mechanism. Synchronous rotation mechanisms for driving the two oil pots 2 are provided at both ends of the lower rotating shaft 13. The transmission shaft 12 and the upper rotating shaft 3 are connected via a linkage mechanism. The linkage mechanism includes a telescopic wheel 25, which is movably mounted on the outer periphery of the upper rotating shaft 3 via a telescopic assembly. The telescopic wheel 25 is assembled from multiple arc-shaped plates. Rectangular plates 46 are movably mounted on both sides of the frame 4 via a lifting mechanism. Two hydraulic hoists 5 are installed below the rectangular plates 46. Both hydraulic hoists 5 are spliced ​​together from multiple irregular plates. A sliding hole 52 is opened at the top of the rectangular plate 46. A square connecting column 47 is fixedly installed in the sliding hole 52. A conversion mechanism is provided on both sides of the square connecting column 47. The conversion mechanism is used to drive the multiple irregular plates to move horizontally.

[0023] With the above structure, when in use, the oil sauce to be processed is placed into two oil pots 2. Through the cooperation of the transmission mechanism and the synchronous rotation mechanism, the two oil pots 2 are driven to rotate synchronously. At the same time, the transmission shaft 12 drives the telescopic wheel 25 and the upper rotating shaft 3 to rotate through the linkage mechanism. This causes the rectangular plate 46 to move up and down through the lifting mechanism on both sides, thereby causing the two oil-pressing gourds 5 below the rectangular plate 46 to move up and down in the oil pot 2 to press the oil sauce. At different stages, the shape of the oil-pressing gourds 5 can be changed through the conversion mechanism. The irregular plate can be split to form a stirring blade state or spliced ​​to form an oil-pressing gourd state to adapt to the pressing needs at different stages. By adjusting the radius of the telescopic wheel 25 through the telescopic component, the lifting speed of the rectangular plate 46 can be changed, and the vibration frequency can be dynamically adjusted.

[0024] like Figure 2 and Figure 3As shown, the support mechanism includes two fixed plates 6, both of which are U-shaped and fixedly mounted on the base 1. Two support columns 7 are fixedly mounted on the top of each of the two fixed plates 6. An annular plate 8 is fixedly mounted on the top of each of the four support columns 7. Multiple buffer columns 9 are slidably mounted on the annular plate 8. Limiting circular plates are provided at the bottom of each buffer column 9. Support rollers 10 are rotatably mounted on the top of each buffer column 9. All support rollers 10 are made of stainless steel and have a frustum-shaped design at their tops. This frustum-shaped structure provides radial limitation for the oil pan 2, preventing horizontal displacement. The outer periphery of the oil pan 2 is in contact with the multiple support rollers 10, providing stable support when the oil pan rotates. Buffer springs 11 are sleeved on the outer periphery of each buffer column 9. The tops of the multiple buffer springs 11 are connected to the bottoms of the multiple support rollers 10, and the bottoms of the multiple buffer springs 11 are connected to the top of the annular plate 8.

[0025] In this embodiment, the oil pot 2 is placed on multiple support rollers 10, so that the oil pot 2 is in close contact with the multiple support rollers 10. After the oil pot 2 is placed, the elastic action of multiple buffer springs 11 can improve the stability of the oil pot 2 and prevent the oil pot 2 from shaking or tipping over when the base 1 is moved or accidentally bumped, thus causing waste of the oil and sauce inside.

[0026] like Figure 2 and Figure 4 As shown, the transmission mechanism includes a drive motor 66. Specifically, the drive motor 66 can be controlled by a PLC controller. The drive motor 66 is fixedly mounted on one of the support plates 22. A first pulley 14 is fixedly sleeved on both the output shaft of the drive motor 66 and the transmission shaft 12. A second pulley 15 is fixedly sleeved on both the transmission shaft 12 and the lower rotating shaft 13. A first belt 16 is tensioned on each of the first pulley 14 and the second pulley 15. Specifically, the size of the first pulley 14 is smaller than the size of the second pulley 15, thereby achieving deceleration rotation.

[0027] In this embodiment, by starting the drive motor 66, the transmission shaft 12 can be driven to rotate through the transmission action of one of the first pulleys 14, the second pulley 15 and one of the first belts 16. Then, through the transmission action of the other first pulley 14, the second pulley 15 and the other first belt 16, the lower rotating shaft 13 can be driven to rotate. Through the transmission of multiple pulleys and multiple belts, the lower rotating shaft 13 can be driven to rotate slowly, avoiding the phenomenon of rapid rotation of the oil pot 2, which would cause the oil and sauce inside to splatter.

[0028] like Figure 2 and Figure 3As shown, the synchronous rotation mechanism includes two driving bevel gears 20, which are respectively fixedly sleeved at both ends of the lower rotating shaft 13. Connecting plates 17 are fixedly installed on two fixed plates 6 on the same side. Round shafts 18 are rotatably installed on both connecting plates 17. Driven bevel gears 21 are fixedly sleeved on the outer periphery of both round shafts 18. Cross grooves are opened at the top of both round shafts 18. Cross blocks 19 are fixedly installed at the bottom of both oil pots 2. The bottom ends of the two cross blocks 19 extend into the two cross grooves respectively.

[0029] In this embodiment, when the driving bevel gear 20 rotates with the lower rotating shaft 13, it drives the round shaft 18 to rotate through meshing with the driven bevel gear 21. The round shaft 18 then drives the oil pan 2 to rotate synchronously through the engagement of the cross groove and the cross locking block 19. This structural design not only ensures efficient power transmission, but also facilitates the disassembly and cleaning of the oil pan 2. At the same time, the bevel gear transmissions on both sides are symmetrically distributed to ensure that the rotation speed and direction of the two oil pans 2 are completely consistent, thus achieving synchronous operation.

[0030] like Figure 7 and Figure 8 As shown, the telescopic assembly includes a hollow tube 26, which is rotatably sleeved on the outer periphery of the upper rotating shaft 3. Specifically, two mounting plates 23 are fixedly installed on the frame 4, and through holes are opened on the sides of the two mounting plates 23. The upper rotating shaft 3 is rotatably installed in the two through holes. The outer periphery of the hollow tube 26 is provided with a bidirectional threaded groove. Two annular sliding plates 33 are threadedly installed on the outer periphery of the hollow tube 26. Rotating sleeves 35 are rotatably installed on the outer periphery of the two annular sliding plates 33. Both rotating sleeves 35 are octagonal. Multiple first connecting rods 36 are rotatably installed on the outer periphery of the two rotating sleeves 35. The other ends of the multiple first connecting rods 36 are rotatably connected to the inner periphery of multiple arc-shaped plates. The two rotating sleeves 35 have different lengths. An octagonal fixing block 65 is fixedly sleeved on the outer periphery of the upper rotating shaft 3, and one of the rotating sleeves 35 is sleeved on the outside of the octagonal fixing block 65.

[0031] Specifically, guide holes are provided on the sides of both annular slide plates 33, and guide shafts 34 are slidably installed in both guide holes. One end of the guide shaft 34 is fixedly installed on the side of one of the mounting plates 23.

[0032] In this embodiment, when the hollow tube 26 rotates, the two annular sliding plates 33 can be driven to move towards or away from each other through the bidirectional threaded groove drive and the guiding action of the guide shaft 34. Through the pushing and pulling action of the first connecting rod 36, multiple arc-shaped plates are driven to expand outward or contract inward, thereby realizing the adjustment of the diameter of the telescopic wheel 25. When the telescopic wheel 25 rotates, through the connection action of multiple first connecting rods 36, two rotating sleeves 35 can be driven to rotate synchronously. When one of the rotating sleeves 35 rotates, the octagonal fixed block 65 and the upper rotating shaft 3 can be driven to rotate synchronously, thereby driving the two turntables 50 to realize the rotation function.

[0033] like Figure 5 and Figure 6 As shown, the telescopic assembly also includes a U-shaped plate 27. A U-shaped top plate 24 is fixedly installed on the top of the frame 4. The U-shaped plate 27 is fixedly installed on the U-shaped top plate 24. A threaded rod 28 is rotatably installed on one side inner wall of the U-shaped top plate 24. The other end of the threaded rod 28 extends to the outside of the U-shaped plate 27 and is provided with a handwheel 29. A rotating hole is opened on the side inner wall of the U-shaped plate 27. The threaded rod 28 is rotatably installed in the rotating hole. A damping washer 30 is fixedly installed on the circumferential inner wall of the rotating hole. The circumferential inner wall of the damping washer 30 is in contact with the circumferential outer wall of the threaded rod 28. A rack 31 is threadedly installed on the threaded rod 28. A transmission gear 32 is fixedly sleeved on the hollow tube 26. The transmission gear 32 is meshed with the rack 31.

[0034] In this embodiment, the threaded rod 28 is rotatably mounted between the inner wall of the U-shaped plate 27 and the U-shaped top plate 24 via a bearing. When the handwheel 29 is rotated, it can drive the threaded rod 28 to rotate synchronously, and then drive the rack 31 to move horizontally through the thread action. This causes the rack 31 to mesh with the transmission gear 32 fixedly sleeved on the hollow tube 26, driving the hollow tube 26 to rotate, thereby realizing the diameter adjustment function of the telescopic wheel 25.

[0035] like Figure 5 and Figure 6 As shown, the linkage mechanism also includes a compression pulley 43 and a third pulley 44. Telescopic sleeves 37 are fixedly installed on the inner walls of the top plate 24. Telescopic plates 38 are slidably installed inside both telescopic sleeves 37. Compression springs 41 are provided at the bottom of both telescopic plates 38. Specifically, a first limiting shaft 39 is fixedly installed on one inner wall of the telescopic sleeve 37. A limiting hole 40 is opened on the side of the telescopic plate 38. The top end of the first limiting shaft 39 is slidably installed in the limiting hole 40. A rotating rod 42 is fixedly installed on the opposite sides of the two telescopic plates 38. The compression pulley 43 is rotatably sleeved on the rotating rod 42. The third pulley 44 is fixedly sleeved on the transmission shaft 12. A second belt 45 is tensioned and installed on the telescopic wheel 25, the compression pulley 43, and the third pulley 44.

[0036] In this embodiment, when the diameter of the telescopic wheel 25 increases, the tension of the second belt 45 increases accordingly. At this time, the belt will exert downward pressure on the compression pulley 43, forcing the telescopic plate 38 to compress the spring 41 and slide into the telescopic sleeve 37, thereby automatically adjusting the belt tension and preventing the belt from breaking due to excessive tension. When the diameter of the telescopic wheel 25 decreases, the elastic force of the compression spring 41 pushes the telescopic plate 38 upward, causing the compression pulley 43 to lift the belt upward, ensuring that the belt is always in a taut state and ensuring that the power transmission is uninterrupted.

[0037] like Figure 11 As shown, the lifting mechanism includes a lifting shaft 49, a side plate 48 fixedly installed on the side of the support plate 22, the lifting shaft 49 slidably mounted on the side plate 48, a turntable 50 fixedly sleeved at the end of the upper rotating shaft 3, a second connecting rod 51 rotatably mounted on one side of the turntable 50, the other end of the second connecting rod 51 rotatably mounted on the top of the lifting shaft 49, and the bottom end of the lifting shaft 49 fixedly connected to the top of the square connecting column 47.

[0038] In this embodiment, when the upper rotating shaft 3 rotates, it can drive the turntable 50 to rotate synchronously. The eccentric rotation of the turntable 50 is converted into the up-and-down reciprocating motion of the lifting shaft 49 through the second connecting rod 51. When the connection point of the turntable 50 rotates to the highest point, the second connecting rod 51 pulls the lifting shaft 49 to rise; when the connection point rotates to the lowest point, the second connecting rod 51 pushes the lifting shaft 49 to fall. The bottom end of the lifting shaft 49 is fixedly connected to the top of the square connecting column 47. Therefore, the up-and-down movement of the lifting shaft 49 can drive the rectangular plate 46 and the oil-pressing hoist 5 below to rise and fall synchronously, realizing the pressing operation of the material in the oil pot 2.

[0039] like Figure 9 and Figure 10 As shown, the conversion mechanism includes a square fixed plate 54 and multiple square sliding plates 55. A positioning shaft 53 is fixedly installed on the inner side wall of the square connecting column 47 and the sliding hole 52. The square fixed plate 54 is fixedly sleeved on the positioning shaft 53. Multiple square sliding plates 55 are slidably sleeved on the positioning shaft 53. A circular groove is opened on the inner side wall of each square sliding plate 55. A return spring 56 is fixedly installed in the circular groove. The other end of the return spring 56 is connected to the side of the adjacent square sliding plate 55 or square fixed plate 54 to form an elastic connection structure. The top of the two outermost square sliding plates 55 is rotatably installed with a third connecting rod 64. A lifting plate 58 is slidably installed on the outer periphery of the square connecting column 47. The top of the two third connecting rods 64 is rotatably installed on the bottom of the lifting plate 58. A connecting shaft 57 is fixedly installed on the bottom of the square fixed plate 54 and multiple square sliding plates 55. Multiple connecting shafts 57 are connected to multiple irregular plates respectively.

[0040] In this embodiment, when the two outermost square sliding plates 55 move synchronously towards each other, they can compress multiple return springs 56, causing the return springs 56 to be housed in the circular groove. Through the elastic connection mechanism formed by the multiple return springs 56, the other square sliding plates 55 are driven to move, thereby causing the multiple square sliding plates 55 to fit together and the multiple irregular plates to be spliced ​​together to form the oil hopper 5.

[0041] like Figure 11 and Figure 12 As shown, the top of the lifting plate 58 has two rectangular holes 59. The inner side walls of the two rectangular holes 59 are fixedly installed with second limiting shafts 60. T-shaped locking blocks 61 are slidably sleeved on the two second limiting shafts 60. Compression springs 62 are sleeved on the two second limiting shafts 60. Two slots 63 are opened on both sides of the square connecting column 47. One end of the two T-shaped locking blocks 61 extends into one of the two slots 63 respectively.

[0042] In this implementation scheme, when it is necessary to change the form of the oil-closing hoist 5, the T-shaped locking blocks 61 are pulled to both sides to disengage them from the upper locking slot 63, the lifting plate 58 is moved downward to the appropriate position, the T-shaped locking blocks 61 are released, the compression springs 62 are reset and push the locking blocks into the lower locking slot 63, thus completing the positioning of the lifting plate 58. When the lifting plate 58 moves, it drives the two square sliding plates 55 on the outside to move through the third connecting rod 64. Under the linkage of multiple compression springs 62, all the square sliding plates 55 move synchronously, thereby driving multiple irregular plates to unfold or retract, realizing the conversion of the oil-closing hoist 5 between the two forms of whole oil-closing and split mixing.

[0043] The working principle and usage process of this invention are as follows: In use, firstly, the two T-shaped locking blocks 61 are moved in opposite directions to release their engagement with the two upper locking slots 63, and the compression springs 62 on both sides are compressed respectively. The lifting plate 58 is moved downward so that the two T-shaped locking blocks 61 correspond to the two lower locking slots 63, releasing the limiting position of the T-shaped locking blocks 61. Through the elastic action of the compression springs 62, the two T-shaped locking blocks 61 can be driven to move towards each other to reset, thereby limiting the lifting plate 58. During the downward movement of the lifting plate 58, under the connection of the third connecting rod 64, it can drive the two square sliding plates 55 that are matched in each phase to move synchronously in opposite directions. When multiple square sliding plates 55 move, they can drive multiple connecting shafts 57 and multiple irregular plates to move synchronously, so that the oil hopper 5 is split into multiple stirring blades, which facilitates breaking the particle suspension stability and promoting the aggregation of small particles into large particles.

[0044] The drive motor 66 is started, which drives the transmission shaft 12 and the lower rotating shaft 13 to rotate through the meshing of the two first pulleys 14, the two second pulleys 15 and the two first belts 16. When the lower rotating shaft 13 rotates, it can drive the active bevel gears 20 at both ends to rotate synchronously. Through the meshing of the active bevel gears 20 and the driven bevel gears 21, the round shaft 18, the cross block 19 and the oil pot 2 are driven to rotate, thereby working with multiple stirring blades to break the suspension stability of particles in the oil sauce and improve the oil pressing efficiency.

[0045] When the drive shaft 12 rotates, the telescopic wheel 25 is driven to rotate through the transmission action of the third pulley 44, the telescopic wheel 25, the extrusion pulley 43, and the third pulley 44. When the telescopic wheel 25 rotates, it can drive the two rotating sleeves 35 to rotate synchronously under the connection of multiple first connecting rods 36. When one of the rotating sleeves 35 rotates, it can drive the upper rotating shaft 3 to rotate synchronously through the connection with the octagonal fixed block 65. When the upper rotating shaft 3 rotates, it can drive the two turntables 50 on both sides to rotate synchronously. Then, through the connection of the second connecting rod 51, it drives the two lifting shafts 49 to drive the two rectangular plates 46 to reciprocate up and down, further improving the effect of breaking the stability of particle suspension.

[0046] After stirring for a period of time, in order to avoid the multiple stirring blades damaging the already formed large particle clusters, the above steps can be used to drive the two lifting plates 58 to move upward synchronously and fix them. When the lifting plates 58 move upward, through the connection of the two third connecting rods 64, the two square sliding plates 55 that are furthest apart move towards each other synchronously. Then, through the squeezing action, the other square sliding plates 55 are driven to move. Through the multiple square sliding plates 55, the multiple connecting shafts 57 and multiple irregular plates are reset, so that the multiple irregular plates are spliced ​​together to form the oil-blocking gourd 5. The up and down vibration of the multiple oil-blocking gourds 5 replaces the stirring of multiple stirring blades, which can not only continue to improve the oil-blocking efficiency, but also avoid damaging the already formed large particle clusters.

[0047] When it is necessary to adjust the lifting speed of the hoist 5, turn the handwheel 29 to drive the threaded rod 28 to rotate. Then, through the meshing of the threaded rod 28 and the rack 31, the rack 31 is driven to mesh with the transmission gear 32. The transmission gear 32 drives the hollow tube 26 to rotate synchronously. Then, through the thread action and the limiting action of the guide shaft 34 on the two annular slide plates 33, the two annular slide plates 33 are driven to move synchronously towards each other. The annular slide plates 33 drive the rotating sleeve 35 to move synchronously. Then, under the connection of multiple first connecting rods 36, multiple arc plates are driven to move synchronously away from the axis, thereby increasing the radius of the telescopic wheel 25, thereby adjusting the rotation speed of the upper rotating shaft 3. By adjusting the rotation speed of the upper rotating shaft 3, the rotation speed of the turntable 50 is adjusted. Then, through the connection of the second connecting rod 51, the lifting speed of the lifting shaft 49 is adjusted, thereby adjusting the vibration speed of the hoist 5.

[0048] When the radius of the telescopic wheel 25 increases, the tension of the second belt 45 increases. At this time, the second belt 45 squeezes the compression pulley 43, causing the two telescopic plates 38 to slide into the two telescopic sleeves 37 respectively, adjusting the tension of the second belt 45 and preventing breakage.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
