Description

Technical Field

[0001] The invention relates to the technical field of oil pressing, in particular to a small and medium-sized oil residue separation and re-pressing type oil pressing device. Background Art

[0002] An oil press is a device used to convert crops such as peanuts into oil. After the oil is pressed, there will be some oil residues, and some oil will remain inside the oil residues. If the oil residues are directly discarded, it will cause a waste of resources. In order to increase the adequacy of oil pressing, it is generally necessary to recycle the oil residues through a re-pressing oil press and re-press the oil residues.

[0003] When the existing re-pressing oil pressing device is pressing oil, it is necessary to wrap the oil residue with gauze, place the oil residue wrapped with gauze in an oil pressing chamber, and then squeeze the oil out of the oil residue by squeezing, and let it flow out from the filter hole. However, in the process of pressing oil, a small amount of impurities will still be squeezed out with the oil. When the squeezed impurities pass through the filter hole, they will remain in the filter hole. If the impurities in the filter hole cannot be processed in time, the purity of the oil will be affected during the next pressing, and the effect and quality of the oil pressing will be reduced.

[0015] The present invention has the following beneficial effects:

[0016] 1. In the small and medium-sized oil residue separation and re-pressing oil pressing device, after the oil residue is re-pressed, the limit frame is reset, and the sliding rod slides inside the rotating groove through the rotation of the rotating disk, and the sliding rod drives the first sliding protrusion to slide inside the first track groove, so that the first sliding protrusion can drive the sliding rod to move in the direction of the limit frame, and the sliding rod pushes the side plate to move, and the side plate drives the tamping rod to move, and the tamping rod drives the cleaning piece to move, so that the cleaning piece is inserted into the filter hole to clean the inside of the filter hole, so as to facilitate the removal of impurities inside the filter hole after the oil residue is re-pressed, reduce the influence of impurities on subsequent oil pressing, and help improve the purity and quality of subsequent oil pressing.

[0017] 2. In the small and medium-sized oil residue separation and re-pressing type oil pressing device, after the cleaning piece cleans the impurities inside the filter hole, before the cleaning piece is reset, the core rod slides inside the rotating groove, and the core rod drives the second sliding protrusion to slide inside the second track groove, so that when the rotating disk is reversed, the core rod can slide relative to the sliding rod, so that the core rod can pull the piston plate to slide inside the active cavity, so that the piston plate sucks the gas inside the air cavity into the active cavity through the air guide groove, and after the gas inside the air cavity is sucked out, the cleaning piece will shrink and become deflated, and then when the cleaning piece is moved out of the filter hole, the surface of the cleaning piece will no longer contact the inner wall of the filter hole, thereby reducing the wear on the cleaning piece and facilitating increasing the service life of the cleaning piece;

[0018] In addition, during the deflation process, the end surface of the cleaning piece will be folded. By utilizing the folding effect, impurities adhering to the surface of the cleaning piece can be further removed, making it easier for the impurities to fall off, thereby improving the removal effect of impurities.

[0019] 3. In the medium and small oil residue separation and re-pressing oil pressing device, during the process of the cleaning piece shrinking and deflation, the piston plate drives the resistance rod to move, so that the resistance block loses the resistance of the resistance rod, and at the same time the second spring unloads the force, so that the movable plate moves, and the movement of the movable plate causes the knocking rod to slide relative to the movable plate, and the knocking rod drives the third sliding protrusion to slide along the third track groove, so that the third sliding protrusion can drive the knocking rod to move. When the knocking rod moves, the first spring is first compressed to store force in the first spring. When the cleaning piece is completely deflated, the first spring unloads the force and instantly releases the knocking rod, so that the knocking rod knocks the end face of the tamping rod. The knocking effect is utilized to not only facilitate the removal of impurities adhering to the end face of the tamping rod, but also facilitate the removal of impurities on the end face of the cleaning piece after deflation, thereby further increasing the impurity cleaning effect.

Specific embodiments

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0034] Example 1, please refer to Figures 1 - 12 , a medium and small-sized oil residue separation and re-pressing type oil press, including a fixed base 1, a fixed oil pressing tank 2 for oil outlet on the fixed base 1, a limiting frame 3 that can move up and down above the oil pressing tank 2, filter holes 4 are opened on the limiting frame 3, an oil pressing plate 5 that can move up and down is arranged above the limiting frame 3, a support disc 6 is fixed on the fixed base 1, a rotating disc 7 is rotatably arranged on the support disc 6, a side plate 8 is arranged inside the rotating disc 7, a pestle rod 9 is fixed on the side plate 8, a cleaning part 10 for cleaning the filter holes 4 is fixed on the pestle rod 9, a rotating groove 11 is opened inside the rotating disc 7, a sliding rod 12 is fixed on the surface of the side plate 8, and the cleaning part 10 slides into the filter holes 4 through the sliding rod 12 inside the rotating groove 11 to clean impurities;

[0035] A servo motor 13 is fixed on the support disk 6, a gear 14 is fixed at the output end of the servo motor 13, a toothed ring 15 is fixed on the surface of the rotating disk 7, and the toothed ring 15 meshes with the gear 14;

[0036] A first sliding protrusion 16 is fixed at the end of the sliding rod 12, and a first track groove 17 for the first sliding protrusion 16 to slide is formed on the inner wall of the rotating groove 11. The first track groove 17 includes a first translation part 171, a first inward movement part 172 and a second translation part 173 which are connected in series;

[0037] A bottom plate 34 matched with the limit frame 3 is fixed inside the oil pressing tank 2. An oil outlet 35 is communicated with one side of the oil pressing tank 2. A first support rod 36 is fixed between the fixed base 1 and the support disk 6. A second support rod 37 is fixed on the upper surface of the support disk 6. The top of the second support rod 37 is fixed with a top plate 38. A first servo cylinder 39 is fixed on the upper surface of the top plate 38. The output end of the first servo cylinder 39 is fixed with a connecting plate 40, and the connecting plate 40 is fixed with the limit frame 3. A second servo cylinder 41 is fixed on the lower surface of the top plate 38, and the output end of the second servo cylinder 41 is fixed with the oil pressing plate 5.

[0038] In this technical solution, when re-pressing the oil residue, first, the first servo cylinder 39 is used to push the connecting plate 40 downward. The connecting plate 40 drives the limit frame 3 to move downward, so that the limit frame 3 moves onto the bottom plate 34, forming a structure with only an upper opening between the limit frame 3 and the bottom plate 34. Then, the oil residue is wrapped with gauze, and the gauze wrapped with the oil residue is placed into the limit frame 3. Then, the second servo cylinder 41 is used to push the oil pressing plate 5 downward, so that the oil pressing plate 5 presses the oil residue inside the gauze. The pressed oil flows out through the filter holes 4 and falls into the oil pressing tank 2. The valve arranged on the oil outlet 35 is controlled to open, and the pressed oil is discharged. After the oil pressing is completed, the second servo cylinder 41 and the first servo cylinder 39 are reset, so that the pressing plate and the limit frame 3 are reset, and the gauze and the residue wrapped inside the gauze can be taken out together;

[0039] In this application, there are four groups of side plates 8, which are respectively arranged around the limit frame 3. A guide rod 47 is arranged between the side plate 8 and the rotating disk 7. One end of the guide rod 47 is fixed with the side plate 8, and the other end of the guide rod 47 is slidably inserted into the rotating disk 7 to increase the smoothness of the movement of the side plate 8; after the limit frame 3 is reset, the servo motor 13 drives the gear 14 to rotate, the gear 14 drives the toothed ring 15 to rotate, the toothed ring 15 drives the rotating disk 7 to rotate, so that the sliding rod 12 slides inside the rotating groove 11, and the sliding rod 12 drives the first sliding protrusion 16 to slide along the first track groove 17. The movement modes of the four groups of side plates 8 are the same. Taking the Figure 6 left side plate 8 in the middle as an example for illustration, asFigure 7 As shown, the first sliding protrusion 16 first slides along the first translation portion 171, and the side plate 8 remains stationary. Then, the first sliding protrusion 16 slides along the first inward movement portion 172. The first sliding protrusion 16 drives the sliding rod 12 to move to the right. The sliding rod 12 moving to the right drives the side plate 8 to move towards the limit frame 3. The side plate 8 drives the ramming rod 9 to move to the right. The ramming rod 9 drives the cleaning member 10 to move to the right, so that the cleaning member 10 is inserted into the filter hole 4. The cleaning member 10 abuts against the surface of the filter hole 4, so that when the cleaning member 10 is inserted into the filter hole 4, the impurities on the inner wall of the filter hole 4 can be cleaned. When the first sliding protrusion 16 slides to the second translation portion 173, the cleaning member 10 has completely passed through from the other side of the filter hole 4, and the cleaning of the filter hole 4 is completed. Then, the servo motor 13 drives the gear 14 to reverse. The gear 14 drives the toothed ring 15 to reverse, so that the rotating disc 7 is reversely reset. The rotating disc 7 reverses, so that the first sliding protrusion 16 slides reversely along the first track groove 17, so that the side plate 8 is reset, thereby driving the cleaning member 10 to be reset.

[0040] Embodiment 2. When the cleaning member 10 cleans the filter hole 4, when the cleaning member 10 is inserted into the filter hole 4, it is necessary to remove the impurities from the inside of the filter hole 4 through the friction between the cleaning member 10 and the filter hole 4. And after the filter hole 4 is cleaned, when the cleaning member 10 is pulled out from the inside of the filter hole 4, there will still be friction between the cleaning member 10 and the filter hole 4. After the filter hole 4 is cleaned, the cleaning member 10 no longer needs to frictionally abut against the inner wall of the filter hole 4. If the friction between the cleaning member 10 and the filter hole 4 is continued, the loss on the surface of the cleaning member 10 is increased, and the service life of the cleaning member 10 is reduced. To solve this problem, this embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 - 12 , a core rod 18 is slidably arranged in the sliding rod 12 and the side plate 8. An activity cavity 19 is opened inside the side plate 8. A piston plate 20 is slidably arranged in the activity cavity 19. The piston plate 20 is fixed to the end of the core rod 18. An air guide groove 21 is opened in the activity cavity 19 and the inside of the ramming rod 9. An air cavity 22 is opened inside the cleaning member 10. The air cavity 22 is communicated with the activity cavity 19 through the air guide groove 21;

[0041] A second sliding protrusion 23 is fixed to the end of the core rod 18. A second track groove 24 for the second sliding protrusion 23 to slide is opened on the inner wall of the rotation groove 11;

[0042] The second track groove 24 includes a third translation portion 241, a second inward movement portion 242, a fourth translation portion 243, a first outward movement portion 244, a second outward movement portion 245, and a third inward movement portion 246 that are communicated. An elastic first rotating plate 247 is arranged between the connection points of the first outward movement portion 244 and the second outward movement portion 245. An elastic second rotating plate 248 is arranged between the connection points of the third inward movement portion 246 and the third translation portion 241.

[0043] In this technical solution, the trajectories of the third translation part 241 and the first translation part 171 are the same, the trajectories of the second inward movement part 242 and the first inward movement part 172 are the same, and the trajectories of the fourth translation part 243 and the second translation part 173 are the same. When the second sliding protrusion 23 slides along the third translation part 241, the second inward movement part 242, and the fourth translation part 243, the core rod 18 and the sliding rod 12 remain relatively stationary. When the first sliding protrusion 16 slides reversely along the second translation part 173, that is, when the rotary disk 7 drives the ram rod 9 and the cleaning part 10 to move outward to the outside of the filter hole 4, due to the resistance of the first rotating plate 247, the second sliding protrusion 23 can only slide along the first outward movement part 244. At this time, the core rod 18 moves leftward relative to the sliding rod 12, as Figure 8 shown. The leftward movement of the core rod 18 drives the piston plate 20 to move leftward in the movable cavity 19. The piston plate 20 sucks the gas inside the air cavity 22 into the movable cavity 19 through the air guide groove 21. The cleaning part 10 can be deformed and can be made of rubber. After the gas inside the air cavity 22 is sucked out, the cleaning part 10 becomes deflated and shrinks. After the cleaning part 10 is completely deflated, at this time, the first sliding protrusion 16 slides reversely to the connection part of the second translation part 173 and the first inward movement part 172, and the second sliding protrusion 23 slides to the connection part of the first outward movement part 244 and the second outward movement part 245. Then the trajectories of the second outward movement part 245 and the first inward movement part 172 are the same. When the second sliding protrusion 23 slides counterclockwise along the second outward movement part 245, the relative positions of the core rod 18 and the sliding rod 12 remain unchanged, so that the cleaning part 10 can be pulled out from the filter hole 4 in the deflated state, avoiding frictional wear between the cleaning part 10 and the filter hole 4 during the pulling process, thereby improving the service life of the cleaning part 10; finally, when the first sliding protrusion 16 slides along the first translation part 171, the second sliding protrusion 23 slides along the third inward movement part 246. At this time, the core rod 18 moves rightward relative to the sliding rod 12, so that the relative positions of the core rod 18 and the sliding rod 12 are reset to the initial state, so that the piston plate 20 fills the gas inside the movable cavity 19 into the air cavity 22 again through the air guide groove 21, making the cleaning part 10 expand and reset for the next cleaning;

[0044] In this technical solution, when the cleaning part 10 cleans the impurities on the inner wall of the filter hole 4, the impurities at the cleaning position are located at the end of the cleaning part 10. When the cleaning part 10 passes through the filter hole 4, some impurities directly fall off, and a small amount of impurities will adhere to the surface of the end of the cleaning part 10 and are not easy to fall off. Therefore, during the deflation process of the cleaning part 10, the surface of the cleaning part 10 will be deformed, and the cleaning part 10 will shrink inward. During the shrinking process, the end face of the cleaning part 10 will fold. Using the folding effect, the impurities adhering to the surface of the cleaning part 10 can be further removed, facilitating the falling of the impurities, thereby improving the removal effect of the impurities.

[0045] In this technical solution, through the setting of the first rotating plate 247, the second sliding protrusion 23 can only slide along the fourth translation part 243 towards the first outward translation part 244, and cannot slide from the first translation part 171 towards the fourth translation part 243. Through the setting of the second rotating plate 248, the second sliding protrusion 23 can only slide along the third inward translation part 246 towards the third translation part 241, and cannot slide from the third translation part 241 towards the third inward translation part 246. For the specific structural analysis, please refer to the content in Embodiment 3.

[0046] Embodiment 3: When the cleaning member 10 cleans the impurities inside the filter hole 4, when the end of the cleaning member 10 cleans the impurities from the inside of the filter hole 4, the fallen impurities accumulate at the front end of the ram rod 9. During the process of pushing the impurities out of the filter hole 4, the impurities may adhere to the end face of the ram rod 9, resulting in inconvenient cleaning and thus reducing the impurity removal effect. To address this problem, this embodiment is an improvement based on Embodiment 2. Specifically, please refer to Figures 1 - 12 , a movable groove 25 is formed inside the side plate 8, a movable plate 26 is elastically arranged inside the movable groove 25, a contact rod 27 is fixed on the surface of the piston plate 20, a contact block 28 for contacting the contact rod 27 is fixed at the end of the movable plate 26, a knocking rod 29 is elastically arranged inside the ram rod 9, the end of the knocking rod 29 is slidably connected to the movable plate 26, a third sliding protrusion 30 is fixed at the end of the knocking rod 29, and a third track groove 31 for the third sliding protrusion 30 to slide is formed on the inner wall of the movable plate 26;

[0047] The third track groove 31 includes an inclined part 311, a knocking part 312, and a reset part 313 that are connected in communication. A third rotating plate 314 is elastically arranged between the connection between the reset part 313 and the inclined part 311;

[0048] A first spring 32 is fixed between the inside of the movable groove 25 and the movable plate 26. A second spring 33 is sleeved on the circumference of the knocking rod 29. One end of the second spring 33 is fixed to the side plate 8, and the other end of the second spring 33 is fixed to the knocking rod 29.

[0049] In this technical solution, as Figure 10 and Figure 11As shown, the first spring 32 is in a compressed and energy - storing state. When the piston plate 20 moves leftward in the movable cavity 19, the piston plate 20 drives the abutting rod 27 to move leftward. The abutting block 28 loses the abutment of the abutting rod 27, and the first spring 32 stores energy, causing the movable plate 26 to slide upward inside the movable groove 25. The upward movement of the movable plate 26 makes the knocking rod 29 slide relative to the movable rod. The knocking rod 29 drives the third sliding protrusion 30 to slide along the inclined portion 311 first, causing the knocking rod 29 to move leftward. The knocking rod 29 moves leftward to compress the second spring 33, storing energy in the second spring 33. When the third sliding protrusion 30 slides to the knocking portion 312, the third sliding protrusion 30 loses the abutment, and at the same time, the second spring 33 releases its force. The knocking rod 29 is instantaneously released, causing the second sliding protrusion 23 to slide along the knocking portion 312, so that the knocking rod 29 knocks on the end face of the ramming rod 9, facilitating the removal of impurities adhered to the surface of the ramming rod 9 and further improving the impurity removal effect. When the piston plate 20 moves rightward for reset, the abutting rod 27 moves rightward to abut against the abutting block 28, prompting the movable plate 26 to move downward and compressing the first spring 32. The downward movement of the movable plate 26 causes the third sliding protrusion 30 to slide along the reset portion 313 until the reset is completed;

[0050] In this technical solution, through the arranged third rotating plate 314, the third sliding protrusion 30 can only slide from the reset portion 313 to the inclined portion 311, and will not make the third sliding protrusion 30 slide from the inclined portion 311 to the reset portion 313. The structures and principles of the first rotating plate 247, the second rotating plate 248, and the third rotating plate 314 are the same in part. The following takes the structure of the third rotating plate 314 as an example for detailed description. As Figure 12 shown, a rotating groove 42 is opened inside the movable plate 26. A rotating rod 43 is fixed in the rotating groove 42. The third rotating plate 314 is fixedly sleeved on the circumference of the rotating rod 43. A limiting block 44 is fixed on the surface of the third rotating plate 314. A stop block 45 that abuts against the limiting block 44 is fixed on the inner wall of the rotating groove 42. A torsion spring 46 is sleeved on the circumference of the rotating rod 43. The a - end of the torsion spring 46 is fixed to the surface of the third rotating plate 314, and the b - end of the torsion spring 46 is fixed to the inner wall of the rotating groove 42. When the third sliding protrusion 30 slides upward along the reset portion 313, the third sliding protrusion 30 abuts against the third rotating plate 314, prompting the third rotating plate 314 to rotate counterclockwise, and the torsion spring 46 stores energy. When the third sliding protrusion 30 slides to the top of the inclined portion 311, the third rotating plate 314 loses the abutment of the third sliding protrusion 30, and the torsion spring 46 releases its force, causing the third rotating plate 314 to reset to Figure 12 the state. Then when the third sliding protrusion 30 slides downward, due to the abutment of the stop block 45 against the limiting block 44, the third rotating plate 314 will not rotate Figure 12The state rotates clockwise. Due to the restriction of the third rotating plate 314, the third sliding protrusion 30 can only slide along the inclined portion 311, so as to realize the cyclic movement of the third sliding protrusion 30 along the third track groove 31.
