The bottom of the two support plates is provided with a bottom plate located on the upper surface of the oil storage tank, and the bottom plate is an isosceles trapezoidal arrangement. Both sides of the upper surface of the bottom plate are convex, and the outer end of the bottom plate is supported on the push plate, and the width of the end of the bottom plate close to the oil inlet groove is smaller than the width of the oil inlet groove.

[0012] A camellia oil extraction method, the method comprising: step 1: pouring camellia oil seeds from a feed port, and crushing the camellia oil seeds by driving a crushing blade through a crushing motor; step 2: coarsely filtering the crushed camellia oil seed powder through a filter, so that the small diameter is ground and the large diameter is further crushed; step 3: the camellia oil seed powder passing through the filter is driven by a grinding motor to grind the camellia oil seed powder, and the ground camellia oil seed powder passes through a discharge cavity and is introduced into an extraction component from a discharge port; step 5: the camellia oil seed powder falls from the discharge port onto a bottom plate between two clamping plates, and a controller performs timing control. When the time is up, a sixteen-station divider rotates one station, and step 6: the hydraulic electric push rod is extended and retracted. The rod extends to push the push plate, so that the two splints are clamped under the action of the limiting roller, so that the camellia oil seed powder located between the two splints squeezes out the camellia oil inside under the action of pressure, and the camellia oil flows from the surface of the bottom plate to the oil inlet groove and then into the oil storage tank; Step seven: After the sixteen-station divider rotates fourteen stations, the telescopic rod of the hydraulic electric push rod contracts, so that the two splints are pulled back to the starting position, and under the action of the elastic component, the two sides of the push plate open the two splints. After the opening is completed, the camellia oil seed powder residue between the two splints falls under the action of gravity and is automatically discharged through the slag discharge groove; Step eight: The telescopic rod of the cylinder extends to reinsert the bottom plate into the bottom of the two splints.

[0013] Beneficial effects: 1. The sixteen-station divider drives the extraction component to rotate and allocate sixteen rotating stations for extracting camellia oil. The extraction component divides the camellia oil into small pieces, which can avoid the situation where the camellia oil seed powder overflows during cold pressing extraction and cannot overflow in time. The camellia oil seed powder residue after extraction can be automatically discharged, and high-quality camellia oil can be extracted in small quantities and multiple times.

[0014] During the cold pressing extraction, the camellia oil seed powder falls from the discharge port onto the bottom plate between the two clamping plates. The controller performs timing control. When the time is up, the sixteen-station divider rotates one station, and the telescopic rod of the hydraulic electric push rod extends to push the push plate, so that the two clamping plates are clamped under the action of the limiting roller. Under the action of pressure, the camellia oil seed powder between the two clamping plates squeezes out the camellia oil inside, and the camellia oil flows from the surface of the bottom plate to the oil inlet tank, and then into the oil storage tank. At this time, the sixteen-station divider rotates one station, and the telescopic rod of the hydraulic electric push rod extends to push the push plate, so that the two clamping plates are clamped under the action of the limiting roller, so that the camellia oil seed powder between the two clamping plates squeezes out the camellia oil inside, and the camellia oil flows from the surface of the bottom plate to the oil inlet tank, and then into the oil storage tank. The splitter rotates through several stations at regular intervals. At this time, there are camellia oil powder seeds on the bottom plate between the two plywoods of several extraction units for cold pressing extraction. The output of camellia oil also decreases from more to less, and finally to none. After the sixteen-station splitter rotates through fourteen stations, the telescopic rod of the hydraulic electric push rod contracts, so that the two plywoods are pulled back to the starting position. Under the action of the elastic component, the two sides of the push plate open the two plywoods. After the opening is completed, the camellia oil seed powder residue between the two plywoods falls under the action of gravity and is automatically discharged through the slag discharge chute.

[0015] When cold-pressing and extracting is performed through two splints, the camellia oil cold-pressed from the camellia oil seeds can be discharged from the nearest through hole, which can avoid untimely discharge of the camellia oil. When the two splints are loosened, the camellia oil seed powder residue is prevented from re-absorbently absorbing the camellia oil, thereby avoiding a reduction in yield.

[0016] When cold-pressing and extracting through two splints, the camellia oil cold-pressed from the camellia oil seeds can be discharged from the nearest U-shaped groove, which can avoid the camellia oil from being discharged untimely on the surface structure of the splints. When the two splints are loosened, the camellia oil seed powder residue is prevented from re-absorbently absorbing the camellia oil, thereby avoiding a reduction in production.

[0017] Compared with the existing extraction method, the present invention can automatically discharge slag and avoid the camellia oil seed powder residue from re-absorbing the camellia oil when the two clamps are loosened, thereby avoiding a reduction in output. At the same time, the present invention can be automatically controlled by a controller.

[0040] For further reference, Figure 3 and Figure 4The extraction assembly 2 includes an oil storage tank 201 fixed on the sixteen-station divider 1, and a plurality of oil inlet grooves 202 are provided on the upper surface of the oil storage tank 201. A support column 203 is provided in the middle of the upper surface of the oil storage tank 201, and a top pressure plate 204 is provided on the upper surface of the support column 203. An annular peripheral force ring 205 is provided on the periphery of the top pressure plate 204. The bottom of the inner wall of the peripheral force ring 205 is connected to the top edge of the oil storage barrel 201 through a plurality of connecting rods 206. The gap between the peripheral force ring 205 and the oil storage barrel 201 is divided into sixteen slag discharge grooves 207 by a plurality of connecting rods 206. Sixteen extraction units 208 are evenly arranged between the peripheral force ring 205 and the support column 203;

[0041] During specific implementation, the extraction unit 208 performs cold-press extraction on the camellia oil seed powder, and the extracted camellia oil flows from the oil inlet tank 202 into the oil storage tank 201. After rotating fifteen stations, the camellia oil seed powder residue inside the extraction unit 208 is automatically discharged and discharged from the residue discharge tank 207.

[0042] For further reference, Figure 5 and Figure 6 The extraction unit 208 includes two V-shaped splints 281, which are connected by a hinge. The other end of the two splints 281 supports a push plate 283. The outer surface of the push plate 283 is provided with a hydraulic electric push rod 284. The other end of the hydraulic electric push rod 284 is fixedly connected to the inner wall of the peripheral force ring 205. The bottom of the two splints 281 is provided with a bottom plate 282 located on the upper surface of the oil storage tank 201. The bottom plate 282 is set in an isosceles trapezoid. Both sides of the upper surface of the bottom plate 282 are convex, and the outer end of the bottom plate 282 is supported on the push plate 283. The width of one end of 82 close to the oil inlet groove 202 is smaller than that of the oil inlet groove 202. The push plate 283 is arranged in a right-angled U-shape, and both sides of the push plate 283 are connected to the clamping plate 281 through elastic components. The top pressure plate 204 is tightly attached to the top of the clamping plate 281. The lower surface of the top pressure plate 204 is rotatably connected and provided with a plurality of limiting rollers 286. At least four limiting rollers 286 form a group, and the limiting rollers 286 of the same group are distributed in a V-shape along the extension direction of the telescopic rod of the hydraulic electric push rod 284. The limiting rollers 286 of the same group are symmetrically arranged and supported on the outer walls of the two clamping plates 281 respectively.

[0043] In a specific implementation, during cold pressing extraction, the camellia oil seed powder falls from the discharge port 351 onto the bottom plate 282 between the two clamping plates 281. The controller 5 performs timing control. When the time is up, the sixteen-station divider 1 rotates one station, and the telescopic rod of the hydraulic electric push rod 284 extends to push the push plate 283, so that the two clamping plates 281 are clamped under the action of the limiting roller 286. The camellia oil seed powder located between the two clamping plates 281 is squeezed and extracted under the action of pressure. The camellia oil flows from the surface of the bottom plate 282 to the oil inlet groove 202, and then flows into the oil storage tank 201. At this time, the sixteen-station divider 1 rotates through several stations at a regular interval. At this time, there are camellia oil seeds on the bottom plate 282 between the two clamping plates 281 of several extraction units 208 for cold pressing extraction. The amount of camellia oil output also decreases from high to low, and finally to zero. After the sixteen-station divider 1 rotates through fourteen stations, the telescopic rod of the hydraulic electric push rod 284 contracts, causing the two clamping plates 281 to be pulled back to the starting position. Under the action of the elastic component, the two sides of the push plate 283 open the two clamping plates 281. After the opening is completed, the camellia oil seed powder residue between the two clamping plates 281 falls under the action of gravity and is automatically discharged through the slag discharge trough 207.

[0044] The tops of the two clamping plates 281 are sealed by the top pressing plate 204, the bottoms are sealed by the bottom plate 282, and the outer ends are sealed by the push plates 283;

[0045] When the push plate 283 pushes, the two clamping plates 281 are limited by the limiting roller 286 and clamped together to cold-press the camellia oil seed powder inside. At this time, the elastic component is stretched.

[0047] Furthermore, a cylinder 285 is provided in the middle of the bottom plate 282 near one end of the oil inlet tank 202, and the other end of the cylinder 285 is connected to the support column 203;

[0048] During specific implementation, after the camellia oil seed powder residue is automatically discharged, the telescopic rod of the cylinder 285 is extended to re-insert the bottom plate 282 into the bottom of the two clamping plates 281, and the sixteen-station divider 1 rotates one station so that the two clamping plates 281 that have just discharged the camellia oil seed powder residue enter the initial position of cold pressing again, and the cold pressing cycle is carried out.

[0049] Furthermore, the splint 281 is precisely machined to have a number of through holes for overflowing camellia oil;

[0050] In specific implementation, when cold-pressing extraction is performed through the two clamps 281, the camellia oil cold-pressed from the camellia oil seeds can be discharged from the nearest through hole, which can avoid untimely discharge of the camellia oil. When the two clamps 281 are loosened, the camellia oil seed powder residue is prevented from re-absorbently absorbing the camellia oil, thereby avoiding a reduction in production.

[0051] Furthermore, the surface of the splint 281 near the camellia oil seed powder is precisely machined to have a number of vertical U-shaped grooves for overflowing the camellia oil, and the U-shaped grooves and the through holes are staggered.

[0052] In specific implementation, when cold-pressing extraction is performed through the two clamping plates 281, the camellia oil cold-pressed from the camellia oil seeds can be discharged from the nearest U-shaped groove, which can avoid the camellia oil from being discharged untimely on the surface structure of the clamping plates 281. When the two clamping plates 281 are loosened, the camellia oil seed powder residue is prevented from re-absorbently absorbing the camellia oil, thereby avoiding a reduction in production.

[0054] Step 1: Pour camellia oil seeds into the feed port 302, and drive the crushing blades 332 through the crushing motor 333 to crush the camellia oil seeds;

[0056] Step 3: The camellia oil seed powder passes through the filter 306, and the grinding motor 342 drives the grinding disc 341 to grind the camellia oil seed powder. The ground camellia oil seed powder passes through the discharge chamber 305 and is introduced into the extraction component 2 from the discharge port 351;

[0057] Step 4: Camellia oil seed powder falls from the discharge port 351 onto the bottom plate 282 between the two clamping plates 281. The controller 5 performs timing control. When the time is up, the 16-station divider 1 rotates one station.

[0058] Step 5: The telescopic rod of the hydraulic electric push rod 284 extends to push the push plate 283, so that the two clamping plates 281 are clamped together under the action of the limiting roller 286. The camellia oil seed powder between the two clamping plates 281 is squeezed and extracted under the action of pressure. The camellia oil flows from the surface of the bottom plate 282 to the oil inlet groove 202 and then into the oil storage tank 201.

[0059] Step 6: After the sixteen-station divider 1 rotates fourteen stations, the telescopic rod of the hydraulic electric push rod 284 contracts, causing the two clamping plates 281 to be pulled back to the starting position. Under the action of the elastic component, the two sides of the push plate 283 open the two clamping plates 281. After the opening is completed, the camellia oil seed powder residue between the two clamping plates 281 falls under the action of gravity and is automatically discharged through the slag discharge chute 207;

[0060] Step 7: The telescopic rod of the cylinder 285 is extended to allow the bottom plate 282 to be re-inserted into the bottom of the two clamping plates 281.

A camellia oil extraction method, characterized in that: The method is applied to a camellia oil extraction device according to any one of claims 1 to 3, and comprises the following steps: step 1: pouring camellia oil seeds from the feed port (302), and driving the crushing blade (332) to crush the camellia oil seeds by a crushing motor (333); step 2: coarsely filtering the crushed camellia oil seed powder through a filter (306), so that the smaller diameter is ground and the larger diameter is further crushed; step 3: the camellia oil seed powder passing through the filter (306) is ground by a grinding motor ( 342) drives the grinding disc (341) to grind the camellia oil seed powder. After the grinding, the camellia oil seed powder passes through the discharge cavity (305) and is introduced into the extraction component (2) from the discharge port (351). Step 5: The camellia oil seed powder falls from the discharge port (351) onto the bottom plate (282) between the two clamping plates (281). The controller (5) performs timing control. When the time is up, the sixteen-station divider (1) rotates one station. Step 6: The hydraulic electric push rod (284) The telescopic rod extends to push the push plate (283), so that the two clamping plates (281) are clamped under the action of the limiting roller (286), so that the camellia oil seed powder located between the two clamping plates (281) is squeezed and extracted under the action of pressure, and the camellia oil flows from the surface of the bottom plate (282) to the oil inlet groove (202), and then flows into the oil storage tank (201); Step 7: After the sixteen-station divider (1) rotates fourteen stations, the hydraulic The telescopic rod of the electric push rod (284) is retracted, so that the two clamping plates (281) are pulled back to the starting position. Under the action of the elastic component, the two sides of the push plate (283) open the two clamping plates (281). After the opening is completed, the camellia oil seed powder residue between the two clamping plates (281) falls under the action of gravity and is automatically discharged through the residue discharge trough (207); Step 8: The telescopic rod of the cylinder (285) is extended, so that the bottom plate (282) is re-inserted into the bottom of the two clamping plates (281).
