Description

Technical Field

[0001] This utility model relates to the field of sesame oil production technology, specifically to an oil pressing machine for sesame oil production. Background Technology

[0002] Sesame oil made using stone mills is an excellent condiment in daily life, possessing high nutritional value and health benefits. It is produced through stone milling, with the temperature remaining at only around 65 degrees Celsius throughout the grinding process. At this temperature, the main aromatic substances and functional nutrients in the sesame oil are almost entirely preserved, and the oil becomes more fragrant with each grinding. The material produced through this grinding process is called a paste. To extract sesame oil, a certain proportion of high-quality drinking water must be added to the paste. Utilizing the difference in specific gravity between water and oil, and through repeated physical agitation, the water displaces the oil from the paste—this is known as the "water displacement method."

[0003] Generally speaking, the "water displacement method" mainly includes two steps. First, the sauce base is mixed with water and then stirred continuously with a stirring device until it is evenly mixed. This process is called stirring the oil. Second, the oil-water mixture in the oil pot is continuously pressed with a pressing pot or the oil pot is shaken to accelerate the combination of non-oil components in the oil with water and promote the rapid separation of sesame oil. This process is called pressing the oil or shaking the oil.

[0004] In the existing technology, most of the oil pressing devices for sesame oil still adopt an oil pressing machine as shown in the Chinese utility model patent with authorization announcement number CN203487124U. It mainly connects the pressing pot to the drive wheel located above the oil pot through a connecting rod and a hinge shaft. The bottom end of the connecting rod is fixedly connected to the pressing pot, and the top end is hinged to the bottom of the hinge shaft. The connecting rod can slide up and down on the frame, while the top end of the hinge shaft is hinged to the eccentric position of the drive wheel. By rotating the drive wheel, the connecting rod drives the pressing pot to move up and down, thereby realizing the oil pressing work.

[0005] In the production of sesame oil, a single oil pan needs to perform different production processes, switching between stirring, pressing, and shaking the oil as required. When switching from pressing to another process or vice versa, this involves disassembling and reassembling the pressing device. For example, when switching from pressing to shaking, the pressing device needs to be disassembled and the shaking device installed on the drive wheel, and vice versa. This makes the existing pressing devices cumbersome to switch between processes and inconvenient to use, thus affecting the production efficiency of sesame oil. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides an oil-pressing machine for sesame oil production, which solves the problem that the existing oil-pressing devices are cumbersome to switch between and inconvenient to use, thus affecting the efficiency of sesame oil production.

[0007] This utility model is achieved using the following technical solution: an oil pressing machine for sesame oil production, including a frame, on which an oil pot that can be driven to rotate by a first drive mechanism is rotatably mounted; it also includes a trolley, on which an installation column is fixedly mounted, and on the installation column an ​​installation arm that can be driven to move up and down by a second drive mechanism is slidably mounted, and at the end of the installation arm away from the installation column, a pressing pot that can press the oil in the oil pot is fixedly mounted.

[0008] With the above structure, when switching between oil pressing and other processes, it is not necessary to frequently disassemble and install the oil pressing device. By installing the oil pressing device on the trolley, when it is necessary to press the oil-water mixture in the oil pot, simply push the trolley to move the oil pressing device to the position of the oil pot and start it; when it is not necessary to press the oil, simply turn off the oil pressing device and push it to a place where it will not obstruct the machine casing. This makes the switching operation process simpler and improves the overall efficiency of sesame oil production.

[0009] Preferably, there are two oil pots, located at the left and right ends of the frame respectively, and two trolleys, each equipped with a mounting column, mounting arm, and oil-pressing device. The combination of two oil pots and two oil-pressing devices further improves the efficiency of this device in sesame oil production.

[0010] Preferably, a drive housing is fixedly installed on the trolley. The second drive mechanism includes a first motor fixedly installed on the trolley, located inside the drive housing. The output shaft of the first motor is coaxially fixedly connected to a first drive shaft. The end of the first drive shaft away from the first motor is rotatably engaged with the drive housing. A disc is coaxially fixedly connected to the first drive shaft. The bottom end of a first connecting rod is hinged to the disc at an eccentric position. The top end of the first connecting rod is hinged to the bottom end of a sliding arm. The top end of the sliding arm is fixedly connected to the end of the mounting arm away from the oil pot. The sliding arm is slidably engaged with the mounting column. The drive housing is provided with clearance holes for the first connecting rod to move. The first motor drives the disc to rotate, which in turn pushes the sliding arm up and down via the first connecting rod, allowing the oil pot to be patted up and down against the oil-water mixture in the oil pan, completing the oil-patting work. The structure is simple, the operation is convenient, and it has two economic benefits.

[0011] Preferably, a guide rail is fixedly mounted on the side of the mounting post near the sliding arm, and sliders are fixedly mounted on both the upper and lower ends of the sliding arm, with the guide rail and sliders slidingly engaged. Through the engagement of the guide rail and sliders, the sliding arm can only move up and down in the direction of the guide rail, and cannot move left, right, or forward and backward, making the structure of the device more stable.

[0012] Preferably, the mounting arm is L-shaped, and the mounting arm and the sliding arm are fixedly connected to form an inverted U-shape. The U-shape design allows the oil can to extend into the oil pan over the top edge without affecting its vertical movement.

[0013] Preferably, the first drive mechanism includes a second motor fixedly installed within a frame. The output shaft of the second motor is coaxially fixedly connected to a second drive shaft, which rotatably engages with the frame. A third bevel gear is coaxially fixedly connected to the end of the second drive shaft furthest from the second motor. A fourth rotating shaft is also rotatably installed within the frame, and a fourth bevel gear meshing with the third bevel gear is coaxially fixedly connected to the fourth rotating shaft. Both ends of the fourth rotating shaft are also connected to a third rotating shaft via a clutch mechanism. A second bevel gear is coaxially fixedly connected to the third rotating shaft. A second rotating shaft is rotatably installed on the frame, and a first bevel gear meshing with the second bevel gear is coaxially fixedly connected to the second rotating shaft. The top of the second rotating shaft is fixedly connected to an oil pan. Through the engagement of multiple bevel gears and multiple rotating shafts, this device can simultaneously drive two oil pans to rotate using only one second motor, resulting in higher utilization of the second motor.

[0014] Preferably, the clutch mechanism includes fixed discs fixedly mounted at both ends of the fourth rotating shaft, and a pressure plate slidably mounted on one end of the third rotating shaft near the fourth rotating shaft. The fixed discs have several grooves, and the pressure plate has several protrusions that can engage with the grooves. A shift fork rotatably mounted on the outer side of the pressure plate, capable of pushing the pressure plate axially along the third rotating shaft, is provided. A shift block is fixedly mounted on the shift fork, with one end of the shift block extending away from the fourth rotating shaft to the outer side of the frame and slidingly engaging with the frame. A limiting mechanism for limiting the slider is also mounted on the frame. By setting up the clutch mechanism, the second motor in this device can control the power cut-off between the third and fourth rotating shafts when it does not need to drive the oil pan to rotate, but the second motor still needs to operate, thereby preventing it from affecting other processes.

[0015] Preferably, the limiting mechanism includes a mounting base fixedly installed on the outside of the frame, located above the lever. One end of a stop lever is hinged to the mounting base, and in its natural state, the other end of the stop lever is located below one side of the lever. The stop lever prevents the pressure plate from slowly disengaging from the fixed plate when the clutch mechanism is engaged, thus avoiding the disconnection of power transmission between the second and fourth shafts, which would affect the normal operation of the device and the efficiency of sesame oil production.

[0016] Preferably, a drive pulley is coaxially fixedly connected to the second drive shaft, and a first rotating shaft is rotatably mounted on the frame. A driven pulley, connected to the drive pulley via a belt drive, is coaxially fixedly connected to the end of the first rotating shaft closest to the second motor. A rocker arm is fixedly connected to the other end of the first rotating shaft furthest from the second motor, and a second fixed column is fixedly connected to the other end of the rocker arm. A rotating sleeve is rotatably mounted on the second fixed column, and the rotating sleeve is connected to one end of a second connecting rod via a universal joint. A hinge seat is fixedly connected to the other end of the second connecting rod. A rotating column is rotatably mounted at an eccentric position at the bottom of the oil pot, and the rotating column can be hinged to the hinge seat. Through the rocker arm and the second connecting rod, when the hinge seat is hinged to the rotating column and the clutch mechanism is disengaged, the oil pot can swing under the drive of the second motor and the second connecting rod, thereby satisfying other processes in sesame oil production and increasing the applicability of this device.

[0017] Preferably, a placement arm is fixedly mounted on the frame, and a roller is rotatably mounted on the placement arm, allowing the second connecting rod to rest on the roller. By providing the placement arm, the second connecting rod is prevented from dragging on the ground when the hinge seat and the rotating column are not connected, thus preventing unnecessary wear and tear on the second connecting rod and further increasing the service life of the device.

[0018] In summary, the beneficial effects of this utility model are as follows:

[0019] 1. By mounting the oil press on a trolley, during the sesame oil production process, when the oil press is needed, simply push the trolley to position it appropriately, then start the second motor to rotate the oil pan, and then start the first motor to move the oil press up and down, thus completing the oil pressing work. When oil pressing is not needed, the first motor can be turned off, and the oil press trolley can be placed appropriately to avoid interfering with other processes. Compared to traditional oil pressing methods, this device eliminates the process of disassembling and installing the oil press, replacing it with the more direct and convenient pushing of the trolley, thereby simplifying the operation in the sesame oil production process, making the oil pressing process more convenient, and improving the efficiency of sesame oil production.

[0020] 2. Through the transmission between the first rotating shaft and the second motor, the first rotating shaft drives the first connecting rod to move via the rocker arm. Combined with the use of the clutch mechanism, when the clutch mechanism is disengaged and the hinged seat is hinged to the rotating column, the oil pot in this device can swing back and forth under the drive of the second motor, thus realizing the oil-swinging process. This allows the oil pot and its driving device to be applicable to different types of processes, making it more versatile. Furthermore, its simple structure, convenient operation, and multi-purpose functionality make it suitable for large-scale sesame oil production, resulting in good economic benefits.

Detailed Implementation

[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0030] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides an oil-pressing machine for sesame oil production, including an oil-pressing device and an oil pot driving device. The oil pot driving device includes a frame 17, on which an oil pot 15, which can be driven to rotate by a first driving mechanism, is rotatably mounted. Specifically, the top of the oil pot 15 is cylindrical, and the bottom is a frustum-shaped cone, with a hollowed-out cavity in the middle. A base 16 for support is fixedly mounted at the bottom of the oil pot 15, and the base 16 is rotatably mounted on the frame 17. The oil-pressing device in this utility model includes a trolley 1. Specifically, the trolley 1 consists of a flat plate for mounting various components, lockable wheels mounted on the bottom of the flat plate, and a handrail mounted on the top surface of the flat plate. See the specific design for reference. Figure 2 Push. A mounting column 3 is fixedly installed on the trolley 1. A mounting arm 4, which can be driven up and down by a second drive mechanism, is slidably installed on the mounting column 3. A pressing pot 5, which can press the oil in the oil pot 15, is fixedly installed at the end of the mounting arm 4 away from the mounting column 3.

[0033] During the oil pressing process, the pressing pot 5 is often located at the inner edge of the oil pan 15, and the oil pan 15 needs to rotate at a constant speed to make the oil pressing effect better.

[0034] To improve the efficiency of oil pressing, two oil pans 15 are provided, located at the left and right ends of the frame 17 respectively. Correspondingly, two oil pressing devices are also provided, corresponding to the oil pans 15. Although there are two oil pans 15 in this device, they are both driven by the first drive mechanism, resulting in higher utilization.

[0035] A drive housing 2 is fixedly mounted on the trolley 1. The second drive mechanism can be any device that enables the mounting arm 4 to move up and down, such as a direct-drive cylinder. In this embodiment, the second drive mechanism includes a first motor 11 fixedly mounted on the flat surface of the trolley 1, and the first motor 11 is located inside the drive housing 2. The output shaft of the first motor 11 is coaxially fixedly connected to a first drive shaft 12. The end of the first drive shaft 12 away from the first motor 11 is rotatably engaged with the drive housing 2. A disc 13 is coaxially fixedly connected to the first drive shaft 12. A first fixing post 14 is fixedly mounted at an eccentric position on the disc 13. Specifically, the first fixing post 14 is fixedly mounted on the edge of the disc 13. The bottom end of the first connecting rod 7 is rotatably mounted on the first fixed column 14. The top end of the first connecting rod 7 is hinged to the bottom end of the sliding arm 6. The top end of the sliding arm 6 is fixedly connected to the end of the mounting arm 4 away from the pot 5. The sliding arm 6 is in sliding engagement with the mounting column 3. Specifically, a guide rail 8 is fixedly mounted on the side of the mounting column 3 near the sliding arm 6. Slider 9s are fixedly mounted on both the upper and lower ends of the sliding arm 6. The guide rail 8 and the slider 9 are in sliding engagement. The drive housing 2 is provided with a clearance hole 10 for the first connecting rod 7 to move.

[0036] The mounting arm 4 is L-shaped, and the mounting arm 4 is fixedly connected to the sliding arm 6 to form an inverted U-shape. The resulting U-shape allows the kettle 5 to be inserted into the oil pan 15, and the mounting arm 4 will not collide with the top of the oil pan 15 during the up-and-down movement of the kettle 5.

[0037] like Figure 5 , Figure 6 , Figure 7 As shown, the first drive mechanism of this utility model includes a second motor 48 fixedly installed inside the frame 17. The output shaft of the second motor 48 is coaxially fixedly connected to a second drive shaft 49, which is rotatably engaged with the frame 17. A third bevel gear 43 is coaxially fixedly connected to the end of the second drive shaft 49 away from the second motor 48. A fourth rotating shaft 42 is also rotatably installed inside the frame 17. A fourth bevel gear 44, which meshes with the third bevel gear 43, is coaxially fixedly connected to the fourth rotating shaft 42. The two ends of the fourth rotating shaft 42 are also connected to a third rotating shaft 38 via a clutch mechanism. A second bevel gear 37 is coaxially fixedly connected to the third rotating shaft 38. A second rotating shaft 36 is rotatably installed on the frame 17. A first bevel gear 35, which meshes with the second bevel gear 37, is coaxially fixedly connected to the second rotating shaft 36. The top of the second rotating shaft 36 is fixedly connected to the base 16 at the bottom of the oil pan 15.

[0038] The aforementioned clutch mechanism includes fixed discs 41 fixedly mounted at both ends of the fourth rotating shaft 42, and a pressure plate 39 slidably mounted on the end of the third rotating shaft 38 near the fourth rotating shaft 42. Specifically, a groove is provided on the side of the fixed disc 41 near the pressure plate 39, and some protrusions are provided on the pressure plate 39 near the fixed disc 41. The protrusions match the grooves. When the protrusions are inserted into the grooves, the third rotating shaft 38 and the fourth rotating shaft 42 are electrically engaged; otherwise, the electrical engagement between them is disengaged. A shift fork 40 is rotatably mounted on the outer side of the pressure plate 39, capable of pushing the pressure plate 39 to move axially along the third rotating shaft 38. A shift block 29 is fixedly mounted on the shift fork 40. A sliding hole 31 is provided on the back of the frame 17. The end of the shift block 29 away from the fourth rotating shaft 42 extends through the sliding hole 31 to the outer side of the frame 17 and slides in cooperation with the frame 17. A limiting mechanism for limiting the movement of the slider 9 is also mounted on the frame 17.

[0039] Since the distance between the end of the shift block 29 away from the shift fork 40 and the pressure plate 39 is relatively far, in order to make the shift block 29 more stable when controlling the movement of the pressure plate 39, a guide rod 47 is fixedly installed on the frame 17. The end of the shift fork 40 near the shift block 29 is provided with a guide hole, and the shift fork 40 slides with the guide rod 47 through the guide hole.

[0040] If the oil pot in this oil-pressing machine is only used for the oil-pressing process, then the oil pot 15 only needs to rotate, that is, there is no need for the existence of a clutch mechanism. The clutch mechanism is provided in this embodiment mainly because the oil pot 15 is not only used for the oil-pressing process, but can also be used for the oil-swinging process. When the oil pot 15 needs to swing, the power engagement between the clutch mechanisms needs to be disconnected, so as to facilitate the swing of the oil pot 15.

[0041] The main components of the oil pan 15 swishing process include a drive pulley 50 coaxially fixedly mounted on the second drive shaft 49, a first rotating shaft 33 rotatably mounted on the frame 17, and a driven pulley 45 coaxially fixedly connected to the end of the first rotating shaft 33 near the second motor 48, which is connected to the drive pulley 50 via a belt 46. A rocker arm 34 is fixedly connected to the end of the first rotating shaft 33 away from the second motor 48, and a second fixed post 25 is fixedly connected to the other end of the rocker arm 34. A rotating sleeve 24 is rotatably mounted on the second fixed post 25, and the rotating sleeve 24 is connected to one end of the second connecting rod 21 via a universal joint. Specifically, a ball seat 23 is fixedly mounted on the rotating sleeve 24, and a ball socket is provided at the end of the ball seat 23 away from the rotating sleeve 24. A ball head 22 is fixedly connected to the end of the second connecting rod 21 near the ball seat 23, and the ball head 22 is clearance-fitted with the ball socket on the ball seat 23. The other end of the second connecting rod 21 is fixedly connected to a hinge seat 20. A fixed seat 18 is fixedly installed at the eccentric position of the bottom of the oil pot 15, that is, on the frustum-shaped side wall of the oil pot 15. A rotating column 19 is rotatably installed on the fixed seat 18, and the rotating column 19 can be hinged to the hinge seat 20.

[0042] When it is necessary to shake the oil, the hinge seat 20 is hinged to the rotating column 19. The combination of the two is similar to a universal joint. At this time, the rotation of the second motor 48 will drive the rocker arm 34 to rotate. The rocker arm will then drive the oil pot 15 to swing through the second connecting rod 21 to realize the work of shaking the oil.

[0043] When performing the oil shaking process, the hinge seat 20 is hinged to the rotating column 19. However, when performing the oil pressing process, the connection between the rocker arm 34 and the oil pot 15 must be disconnected. The easiest way to disconnect it is to remove the hinge seat 20 from the rotating column 19, while leaving the ball head 22 and ball seat 23 at the other end unchanged. This also facilitates subsequent installation. If the hinge seat 20 is simply removed and left unattended, it will drag on the ground, causing unnecessary wear. Therefore, in this embodiment, a placement arm 26 is also fixedly installed on the frame 17. A roller 27 is rotatably mounted on the placement arm 26, and the second connecting rod 21 can rest on the roller 27.

[0044] like Figure 4 As shown, in this embodiment, the limiting mechanism includes a mounting base 32 fixedly installed on the outside of the frame 17. The mounting base 32 is located above the lever 29, and one end of a stop bar 30 is hinged to the mounting base 32. In its natural state, the other end of the stop bar 30 is located below one side of the lever 29. When it is necessary to move the lever 29, simply lift the stop bar 30 by hand, move the lever 29 to the desired position, and then lower the stop bar 30.

[0045] As a further illustration of this example, the oil pan 15 is also provided with an oil outlet pipe 28 for discharging the contents of the oil pan 15. The oil outlet pipe 28 is normally closed, that is, the end is sealed, and it can be opened when needed.

[0046] The operating principle of this device is as follows: When it is necessary to press the oil-water mixture in the oil pan 15, first observe the oil pan drive device to ensure that the connection between the hinge seat 20 and the rotating column 19 is disconnected. Then observe the clutch mechanism to ensure that the clutch mechanism is in a state where the third rotating shaft 38 and the fourth rotating shaft 42 are engaged. After checking, push the trolley 1 with the pressing pot 5 to a suitable position so that the pressing pot 5 of the oil pressing device can move up and down to press the oil-water mixture in the oil pan 15. Then start the second motor 48, and the oil pan 15 rotates at a constant speed. Then start the first motor 11, and the pressing pot 5 presses the oil-water mixture in the oil pan 15, thereby realizing the pressing work.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
