Description
Technical Field
[0001] This invention belongs to the field of flaxseed oil pressing technology, specifically referring to a novel cold pressing device for flaxseed oil. Background Technology
[0002] Flax is a plant used in traditional Chinese medicine, and flaxseed is the seed produced from flax. Flaxseed can be pressed to extract flaxseed oil, which has high nutritional value. A hydraulic oil press is an automated device that uses hydraulic high-pressure pressing. This equipment provides stable and adjustable high pressure through a hydraulic system, fully pressing the oilseeds and resulting in a high oil yield, making it one of the highest-yielding types of mechanical oil pressing equipment currently available. Furthermore, the hydraulic transmission makes the operation smoother and less labor-intensive, and the overall operation is relatively simple.
[0003] The existing cold pressing equipment for flaxseed oil currently has the following problems: Existing cold pressing equipment for flaxseed oil cannot puncture and break up the compacted cake surface during the pressing process, resulting in a slow oil extraction rate and a reduced overall oil yield. Furthermore, the top feeding mechanism of traditional cold pressing equipment for flaxseed oil often uses a small-tonnage hydraulic cylinder. When a large-tonnage hydraulic cylinder presses the cake more tightly, it will significantly increase the load on the small-tonnage top feeding cylinder, resulting in low cake feeding efficiency and a tendency to jam. Therefore, it cannot meet the existing demand for new cold-pressing equipment for flaxseed oil. Summary of the Invention
[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a novel cold pressing device for flaxseed oil that can puncture the compacted surface of flaxseed after compression, increase the oil extraction rate of flaxseed, reduce the top material load, and assist in the smooth demolding and slag discharge of the cake.
[0005] The technical solution adopted in this solution is as follows: This solution proposes a novel cold pressing device for flaxseed oil, including a base, a support frame, a push-type hydraulic mechanism, and a flow-blocking grooving mechanism. The support frame is located on the upper wall of the base. The push-type hydraulic mechanism includes a pressing component, a push component, an oil pressing component, and a material supporting component. The pressing component is located on the upper wall of the support frame. The push component is located on the upper wall of the base at the end away from the support frame. The oil pressing component is located on the upper wall of the base below the pressing component. The material supporting component is located inside the oil pressing component. The flow-blocking grooving mechanism includes a flow-blocking component, a gas-compressing component, a pressure-relieving component, and a puncture component. The flow-blocking component is located at the bottom of the base. The gas-compressing component is located inside the flow-blocking component. The pressure-relieving component is located on the side wall of the flow-blocking component. The puncture component is located on the inner side wall of the support frame.
[0006] As a further preferred embodiment of the present invention, the pressing assembly includes a pressing cylinder and an upper pressure plate. The pressing cylinder is located on the upper wall of the support frame, and the upper pressure plate is located at the output end of the pressing cylinder. The pushing assembly includes an oil storage cylinder, a pushing cylinder, and a pushing piston. The oil storage cylinder is located on the upper wall of the base at the end away from the support frame. The pushing cylinder is located on the upper wall of the oil storage cylinder. The pushing piston is slidably located on the inner wall of the oil storage cylinder, and the output end of the pushing cylinder is connected to the upper wall of the pushing piston. The oil pressing assembly includes an oil pressing cylinder, an oil guide groove, and an oil collecting plate. The oil drum is located on the upper wall of the base near the support frame. Multiple sets of oil guide grooves are located on the side wall of the oil drum, and the oil guide grooves are interconnected. The oil collecting plate is located on the upper wall of the base outside the oil drum. The material support assembly includes a material support plate, a material support cylinder, a material support piston, and a linkage oil circuit. The material support plate is slidably located on the inner wall of the oil drum. The material support cylinder is located through the oil drum and the base. The material support piston is located through the material support cylinder and the material support plate, and the material support piston and the material support cylinder are slidably connected. The linkage oil circuit is connected between the oil storage cylinder and the material support cylinder.
[0007] In use, in the initial state, the output ends of the pressing cylinder and the push cylinder are in the shortened state, and the bottom wall of the material support plate is in contact with the upper wall of the material support cylinder. The flaxseed to be pressed is placed into the upper wall of the material support plate inside the oil pressing cylinder. Then, the output end of the pressing cylinder extends and drives the upper pressure plate to descend. The upper pressure plate extends into the oil pressing cylinder to squeeze the flaxseed, and the flaxseed oil produced flows into the oil collection tray along the oil guide groove. After the flaxseed oil is pressed, the output end of the pressing cylinder shortens, causing the upper pressure plate to rise away from the upper wall of the flaxseed cake. At this time, the output end of the push cylinder extends and pushes the hydraulic oil inside the oil storage cylinder into the linkage oil circuit through the push piston. The hydraulic oil inside the linkage oil circuit enters the material support cylinder and pushes the material support piston to rise. The material support piston pushes the pressed flaxseed cake out of the pressing cylinder through the material support plate, thus completing the pressing operation of the flaxseed oil.
[0008] Preferably, the flow-blocking assembly includes a pressure oil circuit and a compressor cylinder, the compressor cylinders being symmetrically arranged on both sides of the linkage oil circuit, and the pressure oil circuit being connected between the compressor cylinders and the linkage oil circuit; the air compression assembly includes a drive chamber, a compressor chamber, a powerful spring, a compressor plate, a compressor piston, and a one-way intake valve, the drive chamber being located at the end of the compressor cylinder near the pressure oil circuit and connected to the linkage oil circuit, the compressor chamber being located inside the compressor cylinder outside the drive chamber, the powerful spring being located on the inner wall of the compressor chamber outside the drive chamber and being in a compressed state, and the compressor plate being located on the side of the powerful spring away from the pressure oil circuit, and the compressor plate and the drive chamber being away from the pressure oil circuit. The air compressor piston is inserted between the air compressor chamber and the air compressor plate, and the pressure relief assembly includes a pressure relief valve and a pressure relief pipe. The pressure relief valve is connected to the side of the air compressor cylinder away from the pressure oil circuit, and the pressure relief pipe is connected to the side of the pressure relief valve away from the air compressor cylinder. The air compressor piston is slidably connected to the air compressor chamber. The one-way air inlet valve is connected to the end of the air compressor cylinder near the pressure relief valve. The puncture assembly includes a puncture box, a rubber layer, and puncture blades. The puncture box is symmetrically arranged on the inner sidewalls of both ends of the support frame. The rubber layer is located on the inner wall of the puncture box. Multiple sets of puncture blades penetrate the puncture box and are located on the sidewalls of the rubber layer. The puncture blades are arranged opposite to the oil guide groove.
[0009] In use, the output end of the push cylinder extends to drive the push piston. The push piston slides down along the inside of the oil reservoir, pushing the hydraulic oil inside the oil reservoir into the linkage oil circuit. Since the channel for hydraulic oil to flow into the material support cylinder is blocked by the material support piston, the hydraulic oil pressure overcomes the preload of the strong spring and pushes the air compression piston. The air compression piston drives the air compression plate to compress the air inside the drive chamber. After the space inside the drive chamber is compressed, the pressure gradually increases. When the pressure inside the drive chamber reaches the pressure relief valve's pressure relief threshold, the pressure relief pipe connects to the drive chamber. Gas with impact kinetic energy enters the puncture box through the pressure relief pipe and impacts the rubber layer. The rubber layer deforms after being impacted, and the rubber layer drives the puncture tool to slide along the inner wall of the puncture box into the guide oil groove. The puncture tool punctures the relatively dense flaxseed cake pieces. After the gas inside the drive chamber is discharged, the pressure relief valve returns to its normally closed state. As the hydraulic oil slowly squeezes the air piston, the air plate compresses the air inside the drive chamber. When the pressure relief valve reaches the pressure relief threshold again, the pressure relief valve opens, and the gas inside the drive chamber is sprayed through the puncture box to blow the rubber layer. The rubber layer drives the puncture blade to intermittently puncture the flat sealing surface of the flaxseed cake, so that the grease produced by the extrusion can continuously and smoothly seep out.
[0010] Specifically, the support frame is equipped with a controller on its side wall.
[0011] The controller is electrically connected to both the pressing cylinder and the pushing cylinder.
[0012] The beneficial effects achieved by this solution using the above structure are as follows: Compared with existing technologies, this solution combines a push-type hydraulic mechanism with a slugging mechanism. Through the inclusion of a pressing component, a push-type component, an oil pressing component, a material support component, a slugging component, a pneumatic compression component, a pressure relief component, and a piercing component, the hydraulic oil's flow path is altered during the flaxseed compression process by utilizing the elastic deformation of a powerful spring. The hydraulic oil then pushes a pneumatic piston to compress a pneumatic plate, which in turn compresses the gas inside the drive chamber, giving it impact kinetic energy. With the pressure relief valve releasing the pressure, the gas propels the piercing blades. The surface of the oil cake is pierced to increase the oil extraction rate. During the top material discharge, the deformation of the strong spring can reduce the load pressure of the small-tonnage top-push cylinder. When the output end of the top-push cylinder extends to push the material, the static friction between the oil cake and the inner wall of the oil pressing cylinder is relatively large. The gas-jet piercing blade pierces the oil cake again, introduces air to break the vacuum, and reduces the contact area to weaken the friction. The structural fault makes it easier for the oil cake to be pushed out, thereby reducing the load pressure of the small-tonnage top-push cylinder and improving the pressing efficiency of flaxseed oil.

The linkage oil passage 19 is connected between the oil storage cylinder 8 and the material support cylinder 17.
[0020] The flow-blocking assembly 21 includes a pressure oil passage 22 and a compressor cylinder 23. The compressor cylinder 23 is symmetrically arranged on both sides of the linkage oil passage 19. The pressure oil passage 22 is connected between the compressor cylinder 23 and the linkage oil passage 19. The air compression assembly 24 includes a drive chamber 25, a compressor chamber 26, a powerful spring 27, a compressor plate 28, a compressor piston 37, and a one-way air intake valve 38. The drive chamber 25 is located at the end of the compressor cylinder 23 near the pressure oil passage 22 and is connected to the linkage oil passage 19. The compressor chamber 26 is located inside the compressor cylinder 23 outside the drive chamber 25.

The compressor plate 28 is located on the side of the powerful spring 27 away from the pressure oil passage 22, and the compressor plate 28 and the drive chamber 25 are away from the pressure oil passage 22. The air compressor piston 37 is connected to one side of the air compressor 22 and is disposed between the air compressor chamber 26 and the air compressor plate 28.

The air compressor piston 37 is slidably connected to the air compressor chamber 26. The one-way air inlet valve 38 is connected to the end of the air compressor cylinder 23 near the pressure relief valve 30. The puncture assembly 32 includes a puncture box 33, a rubber layer 34 and a puncture knife 35. The puncture box 33 is symmetrically arranged on the inner sidewalls of both ends of the support frame 2. The rubber layer 34 is disposed on the inner wall of the puncture box 33. Multiple sets of puncture knives 35 penetrate the puncture box 33 and are disposed on the sidewalls of the rubber layer 34. The puncture knife 35 is disposed opposite to the oil guide groove 13.
[0021] The support frame 2 is equipped with a controller 36 on its side wall.
[0022] The controller 36 is electrically connected to the pressing cylinder 5 and the pushing cylinder 9 respectively.
[0023] In actual use, in the initial state, the output ends of the pressing cylinder 5 and the pushing cylinder 9 are in the shortened state. The bottom wall of the material support plate 16 is attached to the upper wall of the material support cylinder 17 at the bottom of the oil pressing cylinder 12. The operator puts the flax seeds to be pressed into the upper wall of the material support plate 16 inside the oil pressing cylinder 12. Then, the controller 36 controls the pressing cylinder 5 to start. The pressing speed of the pressing cylinder 5 is set to 5-8 mm / s, the pressing pressure of the pressing cylinder 5 is 60-80 MPa, and the holding time is 15-30 minutes. The output end of the pressing cylinder 5 extends and drives the upper pressure plate 6 to descend. The upper pressure plate 6 extends into the oil pressing cylinder 12 to squeeze the flax seeds. The flaxseed oil produced flows into the oil collection tray 14 along the oil guide groove 13. As the volume of the flax seeds compressed in the oil extraction cylinder 12 gradually decreases, the tightness of the surface of the formed flax seed cake increases. At this time, the controller 36 controls the jacking oil cylinder 9 to start. The output end of the jacking oil cylinder 9 extends to drive the jacking piston 10. The jacking piston 10 slides and descends along the inside of the oil storage cylinder 8. The jacking piston 10 pushes the hydraulic oil inside the oil storage cylinder 8 into the linkage oil circuit 19. Since the channel for the hydraulic oil to flow into the material supporting cylinder 17 is blocked by the material supporting piston 18, the hydraulic oil uses the elastic deformation of the strong spring 27 to push the air compression piston 37. The set stiffness of the strong spring 27 is 500 - 800 N / mm, the pre-compression amount is 10 - 15 mm, the maximum working stroke is 20 - 30 mm, and the ultimate load is 15000 - 20000 N. The material of the strong spring 27 is 50CrVA (50 chromium vanadium steel). Only when the hydraulic oil pressure overcomes the spring force will the air compression plate 28 move. The area of the jacking piston 10 is A, the hydraulic pressure is P, and the maximum elastic force F of the strong spring 27 satisfies: F < P × A. The air compression piston 37 drives the air compression plate 28 to compress the air inside the drive chamber 25, and the pressure inside the drive chamber 25 gradually increases after the internal space is compressed; The opening pressure of the pressure relief valve is set to 0.5 - 0.8 MPa. After the pressure inside the drive chamber 25 reaches the pressure relief threshold of the pressure relief valve 30, the pressure relief pipe 31 is connected to the drive chamber 25. The gas with impact kinetic energy enters the puncture box 33 through the pressure relief pipe 31 and impacts the rubber layer 34. The rubber layer 34 deforms after being impacted. The rubber layer 34 drives the puncture tool 35 to slide along the inner wall of the puncture box 33 into the oil guide groove 13. The puncture tool 35 punctures the flax seed cake with a relatively tight surface. The puncture depth is set to 5 - 10 mm, and the puncture frequency of the puncture tool 35 is 5 - 10 times per minute. An exhaust hole is provided on the side of the puncture box 33 away from the puncture tool 35 to facilitate the discharge of excess gas; After the gas inside the drive chamber 25 is discharged, the pressure relief valve 30 returns to the normally closed state. As the hydraulic oil slowly squeezes the air compression piston 37, when the air compression plate 28 compresses the air inside the drive chamber 25 again to reach the pressure relief threshold of the pressure relief valve 30, the pressure relief valve 30 conducts. The gas inside the drive chamber 25 is sprayed onto the rubber layer 34 through the puncture box 33 again. The rubber layer 34 drives the puncture tool 35 to intermittently puncture the flat and sealed surface of the flax seed cake, enabling the squeezed oil to continuously and smoothly ooze out; After the flaxseed oil is pressed, the controller 36 controls the output end of the pressing cylinder 5 to shorten, causing the upper pressure plate 6 to rise away from the upper wall of the flaxseed cake. At this time, after the pressure plate 28 loses the push of the hydraulic oil, the strong spring 27 deforms and resets, and draws outside air into the drive chamber 25 through the one-way air intake valve 38. The controller 36 controls the push cylinder 9 to start, and the push cylinder 9 pushes at a pressure of 10-16 MPa. The output end of the push cylinder 9 extends and pushes the oil in the storage cylinder 8 through the push piston 10. The hydraulic oil in the hydraulic circuit 19 is pushed into the oil circuit 19. The flow rate of the oil circuit 19 is 10-15L / min. The return speed of the push cylinder 9 is set to 15-20mm / s. The hydraulic oil in the oil circuit 19 enters the material support cylinder 17 and pushes the material support piston 18 to rise. The push speed of the material support cylinder 17 is set to 20-30mm / s. The material support piston 18 pushes the extruded flaxseed cake out of the oil pressing cylinder 12 through the material support plate 16, thus completing the pressing operation of flaxseed oil. When the large-tonnage pressing cylinder 5 compresses the flaxseed cake too tightly, the static friction between the flaxseed cake and the inner wall of the pressing cylinder 12 is large. During the process of the small-tonnage push cylinder 9 pushing the flaxseed cake, the hydraulic oil pressure inside the linkage oil circuit 19 increases. The elastic deformation of the strong spring 27 pushes the air pressure plate 28 to compress the air inside the drive chamber 25. After the pressure inside the drive chamber 25 reaches the threshold of the pressure relief valve 30, the pressurized gas flows into the puncture box 33 through the pressure relief pipe 31 and impacts the rubber layer 34. The deformation of the rubber layer 34 pushes the puncture knife 35 to slide along the inner wall of the puncture box 33 into the oil guide groove 13, puncturing the relatively compact cake and creating structural fractures. As the number of puncture holes on the surface of the cake increases, when the support plate 16 rises, the fracture makes it easier for the edges of the cake to loosen and deform, helping the cake to detach from the oil pressing cylinder 12. After the internal pressure of the linkage oil circuit 19 decreases, the strong spring 27 deforms and resets, causing the air pressure plate 28 to fit against the side wall of the air pressure chamber 26. At the same time, outside air is drawn into the drive chamber 25 through the one-way air intake valve 38. The above operation can be repeated for the next use.

[0025] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
