Description

Technical Field

[0001] The present invention relates to the technical field of pressing and separation, and particularly relates to a nut oil pressing and separation device. Background Art

[0002] Nuts such as walnut kernels, peanuts, and pine nuts are rich in oil. The oil contains unsaturated fatty acids such as fatty acids, oleic acid, and linoleic acid, accounting for more than 80%. The oil pressed from these nuts is widely loved by people because it is easy to be digested and absorbed by the human body and is rich in nutrients. Therefore, it is necessary to press and separate the oil from the nuts.

[0003] For example, a high-efficiency oil pressing device disclosed in the patent with the publication number CN221392419U can press and separate oil. However, during pressing, it does not have the function of automatically moving the material synchronously while pressing, resulting in the material always being in one posture and unable to be evenly pressed, reducing the oil extraction effect of the material during pressing. Therefore, there is an urgent need to design a nut oil pressing and separation device. Summary of the Invention

[0039] Please refer to the attached Figure 1 - attached Figure 6 , in a preferred embodiment, the pressing mechanism includes: a mounting plate 22, the mounting plate 22 is vertically mounted on the bottom of the cross plate 3, an eccentric wheel 21 is rotatably mounted on the side of the mounting plate 22, and a belt 23 is rotatably provided on the other side of the eccentric wheel 21. Both ends inside the belt 23 are provided with belt pulleys 24. The belt pulley 24 located above is rotatably mounted above the cross plate 3, and the belt 23 passes through the cross plate 3. The belt pulley 24 located below is fixedly mounted on the side of the eccentric wheel 21. A third gear 25 is fixedly mounted on the side of the belt pulley 24 located above, and a third rack 26 is vertically fixed to the bottom of the horizontal side of the U-shaped frame 2, and the third gear 25 and the third rack 26 are engaged;

[0040] Specifically, when the pressing plate 12 presses downward, it can also move up and down reciprocally, prompting the pressing plate 12 to apply multiple pressures during pressing, ensuring the pressing effect on the nuts.

[0041] Please refer to the attached Figure 1 - attached Figure 9 , in a preferred embodiment, the discharging assembly includes: a sealing plate 33, the sealing plate 33 is slidably arranged inside the barrel body 5, a bottom plate 27 is horizontally arranged below the base 1, a connecting column 29 is vertically fixedly mounted at the center of the top of the bottom plate 27, and the top end of the connecting column 29 is fixedly mounted at the center of the bottom of the sealing plate 33. Two symmetrically arranged first spring rods 28 are vertically fixed to the top of the bottom plate 27, and the telescopic ends of the two first spring rods 28 are fixedly mounted at the bottom of the base 1. A cylinder 7 is vertically rotatably mounted on the corresponding vertical side of the U-shaped frame 2. An arc-shaped groove 8 and a straight groove 9 are formed on the cylinder 7, and the arc-shaped groove 8 and the straight groove 9 are connected end to end. A U-shaped rod 10 is fixedly mounted on the side of the bottom plate 27, and the end of the upper horizontal side of the U-shaped rod 10 is slidably arranged inside the arc-shaped groove 8 and the straight groove 9. A first bevel gear 13 is fixedly mounted at the top of the cylinder 7 through a connecting shaft, and a second bevel gear 14 is meshed with the side of the first bevel gear 13. A first rotating shaft 17 is horizontally fixedly mounted at the center of the second bevel gear 14, and a first limiting plate 19 fixedly mounted on the side of the vertical side of the U-shaped frame 2 is rotatably sleeved on the surface of the first rotating shaft 17. A first one-way bearing 16 is sleeved on the surface of the first rotating shaft 17, and an outer ring of the first one-way bearing 16 is fixedly sleeved with a first gear 15. A through chute 20 is formed on the corresponding vertical side of the U-shaped frame 2. A connecting plate 11 is horizontally fixedly mounted at the end of the cross plate 3, and the end of the connecting plate 11 passes through the chute 20. A first rack 18 is vertically fixedly mounted at the bottom of the connecting plate 11, and part of the first rack 18 has teeth. When the first rack 18 contacts the first gear 15, the first rack 18 and the first gear 15 are engaged;

[0042] Further, the upward movement of the sealing disc 33 drives the upward movement of the slag, so as to facilitate the lifting of the slag for cleaning. When the hydraulic telescopic rod 4 works upward for the first time, the first rack 18 moves upward to cause the first bevel gear 13 to rotate, so that the U-shaped rod 10 is located at the top of the arc-shaped groove 8 but does not enter the straight groove 9, which is convenient for cleaning the lifted slag. When the hydraulic telescopic rod 4 works upward for the first time, the first rack 18 will cause the first bevel gear 13 to rotate one full circle. The end of the U-shaped rod 10 is located inside the straight groove 9, and the first rack 18 is separated from the first gear 15. The elastic force generated by the first spring rod 28 causes the sealing disc 33 to reset downward.

[0043] Working principle of the present invention: When nuts need to be pressed, first place the nuts inside the barrel body 5, and then start the hydraulic telescopic rod 4 to drive the cross plate 3 to move downward. The downward movement of the cross plate 3 drives the connecting plate 11 to drive the first rack 18 to move downward. During the downward movement of the first rack 18, even after the first rack 18 meshes with the first gear 15, the rotation of the first gear 15 will not drive the first rotating shaft 17 to rotate through the first one-way bearing 16, so that the cylinder 7 will not rotate when the cross plate 3 moves downward;

[0044] The downward movement of the cross plate 3 will also drive the pressing disc 12 to move downward through the second spring rod 31. The pressing disc 12 and the cross plate 3 will drive the connecting components thereon to move downward together. Due to the setting of the third rack 26, when the third gear 25 moves downward, it will also rotate. The rotation of the third gear 25 drives the belt pulley 24 and the belt 23 to rotate. The rotation of the belt pulley 24 drives the eccentric wheel 21 to rotate. The rotation of the eccentric wheel 21 will exert an additional squeezing force on the pressing disc 12 and cause the second spring rod 31 to generate a tensile force. Repeating this process can make the pressing disc 12 move up and down reciprocally while pressing downward, prompting the pressing disc 12 to apply multiple pressures during pressing, ensuring the pressing effect on the nuts;

[0045] The reciprocating up and down movement of the pressure plate 12 drives the connecting components such as the third bevel gear 34, the fourth bevel gear 35, and the second gear 36 to move up and down together. Due to the setting of the second rack 39, when the second gear 36 moves downwards, it will rotate in the positive direction. The positive rotation of the second gear 36 will drive the second rotating shaft 38 to rotate through the second one-way bearing 37. The rotation of the second rotating shaft 38 drives the fourth bevel gear 35 to rotate. The rotation of the fourth bevel gear 35 drives the third bevel gear 34 to rotate. The rotation of the third bevel gear 34 drives the rotating plate 42 to rotate. The rotation of the rotating plate 42 drives the conical column 43 to rotate. When the conical column 43 contacts the extrusion block 30, it will cause the extrusion block 30 to move downwards and generate a tensile force on the third spring rod 41. The downward movement of the extrusion block 30 will affect the interaction force between the materials inside the barrel body 5, resulting in the rearrangement and movement of the materials, and further causing the displacement of the materials, so as to realize that when the extrusion block 30 extrudes some nuts inside the barrel body 5, the nuts inside the barrel body 5 are rearranged, ensuring that the nuts are evenly pressed, improving the pressing effect on the nuts. When the pressure plate 12 moves upwards, when the second gear 36 meshes with the second rack 39, the rotation of the second gear 36 will not drive the second rotating shaft 38 to rotate through the second one-way bearing 37. In summary, by reciprocating in turn, the conical column 43 can always rotate in one direction, and the plurality of extrusion blocks 30 are successively moved downwards, realizing the comprehensive pressing of the nuts inside the barrel body 5;

[0046] As the pressure plate 12 squeezes the nuts inside the barrel body 5, the oil squeezed and separated from the nuts will enter the inside of the cover body 6 through the oil outlet hole 32, and the oil inside the cover body 6 will be discharged through the connecting pipe;

[0047] After the squeezing of the nuts inside the barrel body 5 is completed, the hydraulic telescopic rod 4 drives the cross plate 3 and its connecting components to move upward. The connecting plate 11 moves upward to drive the first rack 18 to move upward. When the first rack 18 starts to move upward, it will not engage with the first gear 15. When the first rack 18 engages with the first gear 15, the rotation of the first gear 15 will drive the first one-way bearing 16, the rotation of the first one-way bearing 16 drives the first rotating shaft 17 to rotate, the rotation of the first rotating shaft 17 drives the second bevel gear 14 to rotate, the rotation of the second bevel gear 14 drives the first bevel gear 13 to rotate, the rotation of the first bevel gear 13 drives the cylinder 7 to rotate, and the rotation of the cylinder 7 causes the U-shaped rod 10 to move upward. The upward movement of the U-shaped rod 10 drives the bottom plate 27 to move upward, the upward movement of the bottom plate 27 drives the connecting column 29 and the sealing disc 33 to move upward, and the upward movement of the sealing disc 33 drives the slag to move upward, so as to realize the lifting of the slag for convenient cleaning of the slag. It should be noted that during the upward movement of the cross plate 3, the first bevel gear 13 will only rotate one circle, and the hydraulic telescopic rod 4 needs to work in two steps when moving upward. The first time is to move the end of the U-shaped rod 10 to the top of the arc-shaped groove 8 and not enter the straight groove 9 yet. The second time is to move the end of the U-shaped rod 10 from the arc-shaped groove 8 into the straight groove 9, and the elastic force generated by the first spring rod 28 will cause the sealing disc 33 to move downward and reset;

[0048] In summary, the reciprocating movement can realize the full squeezing of the nuts, and the discharging is also convenient and fast, thereby improving the use effect of the equipment.

[0049] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
