Description

Technical Field

[0001] This invention belongs to the field of rapeseed oil processing technology, specifically relating to a segmented pre-pressing cake device for traditional pressing. Background Technology

[0002] Traditional pressing is a traditional processing technique that relies on traditional manual skills and uses the principle of physical extrusion to separate solids and liquids from materials. It relies on simple mechanical structures driven by human or animal power, and uses pure physical materials without chemical additives. It is the core process of ancient agricultural product processing. Its development depends on the technological iteration of ancient handicrafts and has adapted to the production scale and material processing needs under the agricultural civilization.

[0003] Patent CN210047115U discloses a household traditional pressing device, including: a base, two support frames, a jack, a material cylinder assembly, a lower piston, a circular stepped top plug, an upper cover, an annular liquid guide plate, and a pressure-bearing cover plate; its key features are: the lower ends of the two support frames are respectively fitted and fixed to both ends of the base; the jack is installed on top of the base; the material cylinder assembly is installed and fixed above the jack on the upper section of the two support frames; the material cylinder assembly has an upper liquid outlet pipe and a lower liquid outlet pipe; the lower piston is installed inside the material cylinder assembly on the upper end of the jack's top rod; the annular liquid guide plate is placed parallel to the lower piston in the middle section of the material being pressed inside the material cylinder assembly; the annular liquid guide plate has radial holes; and the circular stepped top plug is installed... The upper end of the material cylinder assembly presses down on the material being pressed; the upper end cover is placed on the upper port of the material cylinder assembly, and the two ends of the pressure-bearing cover plate are respectively fitted onto the upper ends of the two tension frames and press down on the upper end cover. However, the above device is difficult to accurately control the weight of the oil cake during operation, which easily leads to damage to the disc and the oil-wrapping cloth when the cake is too thick or too thin during the pressing process. During the pre-pressing process, the unevenness of the surface oil material leads to the difficulty of subsequent pressing, which in turn affects the oil extraction efficiency. It is also difficult to achieve automated stacking of the oil cake during pressing, resulting in excessive stacking and vacuum leakage of the oil cake, which affects the final oil extraction effect. Therefore, a segmented pre-pressing cake device for traditional pressing is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a segmented pre-pressing cake device for traditional pressing methods, so as to solve the problem of difficulty in achieving precise control of the weight of the oil cake.

[0005] To achieve the above objectives, the present invention provides a segmented pre-pressing cake device for traditional pressing, comprising: a conveyor table, a weighing mechanism disposed on the left side of the conveyor table, a cake forming mechanism disposed at the bottom of the weighing mechanism, a pre-pressing mechanism disposed on the left side of the cake forming mechanism, and a pressing mechanism disposed at the bottom of the pre-pressing mechanism. The weighing mechanism includes a fixed base, an outer plate fixedly connected to the side of the fixed base, a constraint frame fixedly connected to the inner wall of the outer plate, an electric push rod fixedly connected to the inner wall of the constraint frame, a weighing plate fixedly connected to the telescopic end of the electric push rod, a weight sensor installed inside the weighing plate, the bottom surface of the weighing plate in contact with the top surface of the constraint frame, and the side surface of the weighing plate in contact with the inner wall of the outer plate. During operation, a conveyor table transfers oil to the top surface of the weighing plate. When the weight of the oil accumulated on the surface of the weighing plate reaches a certain threshold... When in position, the weight sensor inside the weighing plate sends an electrical signal to the electric push rod. The electric push rod receives the electrical signal and its telescopic end drives the weighing plate to slide to both sides on the inner wall of the constraint frame. The weight sensor inside the weighing plate controls the electric push rod to pull the weighing plate to both sides, thus achieving accurate weighing of the device. The use of an advanced weighing module in conjunction with the weighing plate for feeding can achieve accurate weighing compared to manual feeding in the past, and completely eliminates the problem of uneven cake thickness, which could lead to damage to the plate and the oilcloth caused by cakes that are too thick or too thin.

[0006] In one or more embodiments of the present invention, a fixing block is fixedly connected to the top surface of the constraint frame, a cable is slidably connected to the inner wall of the fixing block, one end of the cable is fixedly connected to the side of the weighing plate, a limit post is fixedly connected to the side of the fixing seat, a partition plate is slidably connected to the circumferential surface of the limit post by a spring, the side of the partition plate is in contact with the inner wall of the outer plate, and the other end of the cable is fixedly connected to the side of the partition plate.

[0007] In one or more embodiments of the present invention, a retaining barrel is fixedly connected to the surface of the fixed base. A sliding opening is provided on the circumferential surface of the retaining barrel. The surface of the partition plate is in contact with the inner wall of the sliding opening on the retaining barrel. The top surface of the weighing plate is slidably connected to the bottom surface of the retaining barrel. As the weighing plate moves to both sides of the device, the weighing plate drives the pull cable to move to both sides on the inner wall of the fixed block. At this time, due to the movement allowance of the pull cable, the partition plate is driven to move inward by the action of the spring connected between the partition plate and the fixed base, thus completing the isolation when the device discharges material. When the weighing plate moves inward, the weighing plate pulls the pull cable to move inward on the inner wall of the fixed block. The pull cable pulls the partition plate outward and pulls the spring connected between the fixed base and the partition plate to complete the reset. This process is repeated, with the weighing plate pulling the partition plate to move, achieving the effect of isolating the oil inside the retaining barrel after the device has finished weighing. This further ensures the accuracy of the device's weighing of the oil, guarantees the automation of the device's operation, and improves the device's working efficiency.

[0008] In one or more embodiments of the present invention, the cake forming mechanism includes a driven block, the driven block is fixedly connected to the bottom of the weighing plate, a rocker arm is rotatably connected to the surface of the driven block, a limiting plate is fixedly connected to the bottom of the outer plate, and a fixing strip is fixedly connected to the inner wall of the limiting plate.

[0009] In one or more embodiments of the present invention, a driven frame is rotatably connected to the end of the rocker arm away from the driven block. The side of the driven frame is in contact with the inner wall of the limiting plate. A rotating shaft is rotatably connected to the inner wall of the fixing strip. A spiral groove is formed on the circumferential surface of the rotating shaft. The circumferential surface of the rotating shaft is movably connected to the inner wall of the driven frame. A scraper is fixedly connected to the bottom end of the rotating shaft. When the weighing plate moves to both sides, the weighing plate drives the driven block to move to both sides. The driven block drives the rocker arm to move to both sides and rotates at the same time. At this time, the rocker arm pulls the driven frame to slide upward on the inner wall of the limiting plate. While the driven frame slides upward, the driven frame drives the rotating shaft to rotate along the spiral groove formed on the circumferential surface of the rotating shaft. The rotation of the rotating shaft drives the scraper to rotate. The rotation of the scraper driven by the weighing plate realizes the flattening of the oil material that falls on the surface of the base plate, ensuring that the device forms a uniform oil cake. During subsequent pressing, the uniformity of the oil cake is ensured, the fluidity of the cake is reduced, and the deviation of the oil cake during pressing is prevented, which would lead to uneven pressure and thus cause the wrapping cloth to break.

[0010] In one or more embodiments of the present invention, the cake-forming mechanism further includes a worktable, which is fixedly connected to the inner wall of the fixed base. A pad is slidably connected to the inner wall of the worktable, and an electric push rod II is fixedly connected to the inner wall of the worktable. A push plate is fixedly connected to the telescopic end of the electric push rod II. The surface of the push plate is in contact with the inner wall of the worktable. The right side of the pad is fixedly connected to the left side of the push plate. A bottom plate is slidably connected to the inner wall of the pad via a spring. After the cake is wrapped and formed on the bottom plate, the electric push rod II is activated. The telescopic end of the electric push rod II extends and drives the push plate to move to the left on the inner wall of the worktable. The leftward movement of the push plate drives the pad to move to the left, and the leftward movement of the pad drives the bottom plate to move to the left, until the next workstation. The telescopic end of the electric push rod II extends and drives the bottom plate to move to the left. This realizes automated feeding of the device before pressing, avoiding the injury caused by the operator's mistake during feeding, thus ensuring the personal safety of the operator.

[0011] In one or more embodiments of the present invention, the pressing mechanism includes an oil pressing box, the oil pressing box is fixedly connected to the inner wall of the pre-pressing mechanism, a fixing block two is fixedly connected to the inner wall of the oil pressing box, a discharge shaft is rotatably connected to the inner wall of the fixing block two, a roller is fixedly connected to the circumferential surface of the discharge shaft, the roller is arranged on the movement trajectory of the pad, and a discharge plate is fixedly connected to the top end of the discharge shaft.

[0012] In one or more embodiments of the present invention, a pressing plate is slidably connected to the inner wall of the oil pressing box, a feeding block is fixedly connected to the right side of the pressing plate, a lifting cavity is provided on the inner wall of the pad, the feeding block is set on the movement trajectory of the bottom plate, and the feeding block is set on the movement trajectory of the pad. When the pad moves to the left, when the pad moves to the working range of the feeding block, the pad drives the bottom plate to move upward along the inclined surface of the feeding block and stretches the spring connected between the pad and the bottom plate. At the same time as the bottom plate moves upward, the side of the pad contacts the roller and drives the roller to rotate. The rotation of the roller drives the unloading shaft to rotate, and the rotation of the unloading shaft drives the unloading plate to rotate, thus completing the unloading of the oil cake on the bottom plate. The movement of the pad drives the bottom plate to rise while the unloading plate rotates, realizing the effect of pushing the oil on the bottom plate into the pressing station. At the same time, the rotating unloading plate ensures that the distance when the oil is pushed in is consistent, avoiding the tearing of the wrapping cloth due to the uneven position of the oil stacking during pressing, which would lead to the leakage of oil in the oil cake and affect the oil yield of the device.

[0013] In one or more embodiments of the present invention, the pressing mechanism further includes a driven shaft, which is rotatably connected to the inner wall of the oil pressing box. A one-way wheel is fixedly connected to the circumferential surface of the driven shaft. A ratchet is provided inside the one-way wheel to drive the driven shaft to rotate in one direction. A transmission belt is connected to the circumferential surface of the transmission belt.

[0014] In one or more embodiments of the present invention, a lifting shaft is connected to the end of the transmission belt away from the driven shaft. The lifting shaft is rotatably connected to the inner wall of the oil pressing box. A cam is fixedly connected to the circumferential surface of the lifting shaft. The cam is in contact with the inner wall of the worktable. The pressing plate is arranged on the movement trajectory of the cam. A rotating block is rotatably connected to the inner wall of the oil pressing box via a torsion spring. The rotating block is arranged on the movement trajectory of the pressing plate. A storage box is fixedly connected to the left side of the pre-pressing mechanism. The storage box is used to store the pressing plate. When the bottom plate rises and moves to the top of the pad, the pad continues to move to the left. When the pad moves to the working range of the transmission belt, the pad drives the transmission belt upward along the movable cavity opened on the inner wall of the pad. The device moves, with the pad plate moving upward, causing the pressing plate to move upward. The pressing plate then causes the rotating block to rotate. Once the pressing plate has fully risen, the rotating block returns to its original position due to the torsion spring hinged between the rotating block and the oil pressing box. At this point, the pressing plate stored in the storage box slides into the oil pressing box along the inclined surface of the inner wall of the storage box and the feeding wheel on the inclined surface due to gravity. This process repeats, with the pad plate driving the pressing plate upward and the rotating block limiting its position. This achieves automatic stacking of the oil cake, reducing the number of times the cake needs to be added during pressing, thus reducing the labor intensity of the workers. At the same time, it avoids the vacuum leakage of the oil cake caused by the constant application and cessation of pressure on the pre-pressing mechanism due to excessive stacking, which would affect the final oil extraction effect.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The coordinated operation between the fixed base, outer plate, constraint frame, electric push rod 1, weighing plate, fixed block 1, cable, partition plate, limit post, and surrounding barrel is achieved by the electric push rod 1, controlled by the weight sensor inside the weighing plate, which pulls the weighing plate to slide to both sides, thus realizing precise weighing of the device. The use of an advanced weighing module in conjunction with the weighing plate for feeding allows for more accurate weighing compared to manual feeding, and completely eliminates uneven cake thickness, which could lead to damage to the pan and the oilcloth due to cakes that are too thick or too thin. The weighing plate pulls the partition plate to move, achieving the effect of isolating the oil inside the surrounding barrel after the device has completed weighing, further ensuring the accuracy of the device's oil weighing, guaranteeing the automation of the device's operation, and improving the device's working efficiency.

[0016] 2. The coordinated operation between the driven block, rocker arm, limit plate, fixing strip, driven frame, rotating shaft, scraper, pad, worktable, electric push rod II, push plate, and base plate, driven by the weighing plate to rotate the scraper, achieves the leveling of the oil material falling onto the base plate surface, ensuring that the oil material is formed into a uniform cake. During subsequent pressing, this ensures the uniformity of the oil cake, reduces its fluidity, and prevents it from shifting during pressing, which could lead to uneven pressure and tearing of the wrapping cloth. The extension end of electric push rod II moves the base plate to the left, achieving automated feeding before pressing. This avoids the injury to workers caused by errors during feeding, thus ensuring the safety of operators.

[0017] 3. The oil pressing box, fixed block 2, rollers, unloading shaft, unloading plate, pressing plate, feeding block, driven shaft, one-way wheel, transmission belt, lifting shaft, cam, rotating block, and storage box work together. The movement of the pad plate drives the bottom plate to rise while the unloading plate rotates, realizing the effect of pushing the oil on the bottom plate into the pressing station. At the same time, the rotating unloading plate ensures that the distance when the oil is pushed in is consistent, avoiding the cloth from breaking due to uneven stacking of oil during pressing, which would lead to oil leakage from the oil cake and affect the oil yield of the device. The pad plate drives the pressing plate to move upward and is limited by the rotating block, realizing the automatic stacking of the oil cake by the device. This reduces the number of times the stack is added during pressing, reduces the labor intensity of the workers, and avoids the vacuum leakage of the oil cake caused by the constant application and stopping of pressure on the oil cake by the pre-pressing mechanism due to excessive stacking, which would affect the final oil yield.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figure 1-7 As shown, one embodiment of the present invention is: a segmented pre-pressing cake device for traditional pressing, comprising: a conveyor 1, a weighing mechanism 2 arranged on the left side of the conveyor 1, a cake forming mechanism 3 arranged at the bottom of the weighing mechanism 2, a pre-pressing mechanism 4 arranged on the left side of the cake forming mechanism 3, and a pressing mechanism 5 arranged at the bottom of the pre-pressing mechanism 4. The weighing mechanism 2 includes a fixed base 21, an outer plate 22 fixedly connected to the side of the fixed base 21, a constraint frame 23 fixedly connected to the inner wall of the outer plate 22, an electric push rod 24 fixedly connected to the inner wall of the constraint frame 23, and a weighing plate 25 fixedly connected to the telescopic end of the electric push rod 24. A weight sensor is installed inside the weighing plate 25. The bottom surface of the weighing plate 25 is in contact with the top surface of the constraint frame 23, and the side surface of the weighing plate 25 is in contact with the inner wall of the outer plate 22. The electric push rod 24 is controlled by the weight sensor inside the weighing plate 25 to pull the weighing plate 25 to slide to both sides, realizing accurate weighing of the device. The use of an advanced weighing module in conjunction with the weighing plate 25 for feeding can make the feeding more accurate than the previous manual feeding, and completely eliminate the problem of uneven cake thickness, which would cause damage to the pan and the oilcloth due to cakes that are too thick or too thin.

[0022] A fixing block 26 is fixedly connected to the top surface of the constraint frame 23. A cable 27 is slidably connected to the inner wall of the fixing block 26. One end of the cable 27 is fixedly connected to the side of the weighing plate 25. A limit post 29 is fixedly connected to the side of the fixing seat 21. A partition plate 28 is slidably connected to the circumference of the limit post 29 by a spring. The side of the partition plate 28 is in contact with the inner wall of the outer plate 22. The other end of the cable 27 is fixedly connected to the side of the partition plate 28.

[0023] The surface of the fixed base 21 is fixedly connected to the surrounding barrel 210. A sliding opening is provided on the circumferential surface of the surrounding barrel 210. The surface of the partition plate 28 is in contact with the inner wall of the sliding opening on the surrounding barrel 210. The top surface of the weighing plate 25 is slidably connected to the bottom surface of the surrounding barrel 210. The partition plate 28 is moved by the weighing plate 25, which realizes the effect of isolating the oil inside the surrounding barrel 210 after the device has been fully weighed. This further ensures the accuracy of the device in weighing the oil, guarantees the automation of the device operation, and improves the working efficiency of the device.

[0024] The cake forming mechanism 3 includes a driven block 31, which is fixedly connected to the bottom of the weighing plate 25. A rocker arm 32 is rotatably connected to the surface of the driven block 31. A limit plate 33 is fixedly connected to the bottom of the outer plate 22, and a fixing strip 34 is fixedly connected to the inner wall of the limit plate 33.

[0025] The end of the rocker arm 32 away from the driven block 31 is rotatably connected to the driven frame 35. The side of the driven frame 35 is in contact with the inner wall of the limiting plate 33. The inner wall of the fixing strip 34 is rotatably connected to the rotating shaft 36. The circumferential surface of the rotating shaft 36 is provided with a spiral groove. The circumferential surface of the rotating shaft 36 is movably connected to the inner wall of the driven frame 35. The bottom end of the rotating shaft 36 is fixedly connected to the scraper 37. The scraper 37 is driven to rotate by the weighing plate 25, which realizes the flattening of the oil material that falls on the surface of the bottom plate 312. This ensures that the oil material is formed into a uniform cake by the device. During subsequent pressing, the uniformity of the oil cake is ensured, the fluidity of the cake is reduced, and the oil cake is prevented from shifting during pressing, which would lead to uneven pressure and thus cause the wrapping cloth to break.

[0026] The forming mechanism 3 also includes a worktable 39, which is fixedly connected to the inner wall of the fixed base 21. A pad 38 is slidably connected to the inner wall of the worktable 39, and an electric push rod 310 is fixedly connected to the inner wall of the worktable 39. A push plate 311 is fixedly connected to the telescopic end of the electric push rod 310. The surface of the push plate 311 is in contact with the inner wall of the worktable 39. The right side of the pad 38 is fixedly connected to the left side of the push plate 311. A base plate 312 is slidably connected to the inner wall of the pad 38 through a spring. The extension of the telescopic end of the electric push rod 310 drives the base plate 312 to move to the left, realizing automated feeding of the device before pressing. This avoids the injury caused by the operator's mistake during feeding, thus ensuring the personal safety of the operator.

[0027] Working principle: When the device is running, the conveyor 1 transfers the oil to the top surface of the weighing plate 25. When the weight of the oil accumulated on the surface of the weighing plate 25 is reached, the weight sensor inside the weighing plate 25 sends an electrical signal to the electric push rod 24. The electric push rod 24 receives the electrical signal and its telescopic end drives the weighing plate 25 to slide to both sides on the inner wall of the constraint frame 23. The weight sensor inside the weighing plate 25 controls the electric push rod 24 to pull the weighing plate 25 to both sides, thus realizing the accurate weighing of the device. The use of an advanced weighing module in conjunction with the weighing plate 25 for feeding can make the feeding more accurate than the previous manual feeding, and completely eliminate the problem of uneven cake thickness, which would cause damage to the plate and the oilcloth due to cakes that are too thick or too thin. As the weighing plate 25 moves to both sides of the device, it drives the cable 27 to move to both sides along the inner wall of the fixed block 26. At this time, due to the movement allowance of the cable 27, the partition plate 28, under the action of the spring connecting the partition plate 28 and the fixed seat 21, drives the cable 27 to move inward, completing the isolation during the discharge of material from the device. When the weighing plate 25 moves inward, it pulls the cable 27 to move inward along the inner wall of the fixed block 26. The cable 27 pulls the partition plate 28 outward and pulls the spring connecting the fixed seat 21 and the partition plate 28 to complete the reset. This process is repeated, with the weighing plate 25 pulling the partition plate 28 to move, achieving the effect of isolating the oil inside the tank 210 after the device has finished weighing. This further ensures the accuracy of the device's oil weighing, guarantees the automation of the device's operation, and improves the device's working efficiency.

[0028] As the weighing plate 25 moves to both sides, it drives the driven block 31 to move to both sides. The driven block 31, in turn, drives the rocker arm 32 to move to both sides and rotate. At this time, the rocker arm 32 pulls the driven frame 35 to slide upwards along the inner wall of the limiting plate 33. Simultaneously, the driven frame 35 drives the rotating shaft 36 to rotate along the spiral groove on the circumference of the rotating shaft 36. The rotation of the rotating shaft 36 drives the scraper 37 to rotate. The weighing plate 25 drives the scraper 37 to rotate, thus leveling the oil material that has fallen onto the surface of the base plate 312. This ensures that the oil material forms a uniform cake, which is beneficial for subsequent pressing, reducing the cake's fluidity and preventing it from spreading. The offset during pressing leads to uneven pressure, causing the fabric to tear. After the oil cake is formed on the base plate 312, the electric push rod 310 is activated. The extension end of the electric push rod 310 extends, causing the push plate 311 to move to the left on the inner wall of the worktable 39. The leftward movement of the push plate 311 causes the pad 38 to move to the left, which in turn causes the base plate 312 to move to the left until the next station. The extension end of the electric push rod 310 then moves the base plate 312 to the left, thus achieving automated feeding before pressing. This avoids the risk of workers being injured during pressing due to errors in feeding, ensuring the safety of the operators.

[0029] Please see Figure 1-7 Based on the above embodiments, in another embodiment of the present invention, the pressing mechanism 5 includes an oil pressing box 51, which is fixedly connected to the inner wall of the pre-pressing mechanism 4. A fixing block 52 is fixedly connected to the inner wall of the oil pressing box 51, and a discharge shaft 54 ​​is rotatably connected to the inner wall of the fixing block 52. A roller 53 is fixedly connected to the circumferential surface of the discharge shaft 54, and the roller 53 is arranged on the movement trajectory of the pad 38. A discharge plate 55 is fixedly connected to the top end of the discharge shaft 54.

[0030] A pressing plate 56 is slidably connected to the inner wall of the oil pressing box 51. A feeding block 57 is fixedly connected to the right side of the pressing plate 56. A lifting cavity is provided on the inner wall of the pad 38. The feeding block 57 is set on the movement trajectory of the bottom plate 312 and the pad 38. The movement of the pad 38 drives the bottom plate 312 to rise while the unloading plate 55 rotates, which realizes the effect of pushing the oil on the bottom plate 312 into the pressing station. At the same time, the rotating unloading plate 55 ensures that the distance when the oil is pushed in is consistent, avoiding the cloth from breaking due to the uneven position of the oil stacking during pressing, which would cause the oil in the oil cake to leak and affect the oil yield of the device.

[0031] The pressing mechanism 5 also includes a driven shaft 58, which is rotatably connected to the inner wall of the oil pressing box 51. A one-way wheel 59 is fixedly connected to the circumferential surface of the driven shaft 58. A ratchet is provided inside the one-way wheel 59 to drive the driven shaft 58 to rotate in one direction. A transmission belt 510 is connected to the circumferential surface of the transmission belt 510.

[0032] The end of the transmission belt 510 away from the driven shaft 58 is connected to a lifting shaft 511. The lifting shaft 511 is rotatably connected to the inner wall of the oil pressing box 51. A cam 512 is fixedly connected to the circumferential surface of the lifting shaft 511. The cam 512 is in contact with the inner wall of the worktable 39. The pressing plate 56 is set on the movement trajectory of the cam 512. The inner wall of the oil pressing box 51 is rotatably connected to a rotating block 513 through a torsion spring. The rotating block 513 is set on the movement trajectory of the pressing plate 56. A storage box 514 is fixedly connected to the left side of the pre-pressing mechanism 4. The storage box 514 is used to store the pressing plate 56. The pressing plate 56 is driven upward by the pad 38 and limited by the rotating block 513. This realizes the automatic stacking of oil cakes by the device, reduces the number of times the stacks are added during pressing, reduces the labor intensity of the workers, and avoids the vacuum leakage of the oil cakes caused by the constant application and stopping of pressure on the oil cakes by the pre-pressing mechanism 4 due to excessive stacking, which affects the final oil extraction effect.

[0033] Working principle: When the pad 38 moves to the left, when the pad 38 moves into the working range of the feeding block 57, the pad 38 drives the bottom plate 312 to move upward along the inclined surface of the feeding block 57, and stretches the spring connecting the pad 38 and the bottom plate 312. Simultaneously, as the bottom plate 312 moves upward, the side of the pad 38 contacts the roller 53, and the side of the pad 38 drives the roller 53 to rotate. The rotation of the roller 53 drives the unloading shaft 54 ​​to rotate, and the rotation of the unloading shaft 54 ​​drives the unloading plate 55 to rotate. The unloading of the oil cake on the base plate 312 is achieved by the movement of the pad plate 38, which drives the base plate 312 to rise while the unloading plate 55 rotates. This pushes the oil on the base plate 312 into the pressing station. Simultaneously, the rotating unloading plate 55 ensures a consistent distance during oil feeding, preventing the fabric from tearing due to uneven oil stacking during pressing, which could lead to oil leakage from the oil cake and affect the oil yield of the device. When the base plate 312 rises and moves to the top of the pad plate 38, the pad plate 38 continues to move to the left... When the pad 38 moves to the working range of the transmission belt 510, the pad 38 drives the transmission belt 510 to move upward along the movable cavity opened on the inner wall of the pad 38. The upward movement of the pad 38 drives the pressing plate 56 to move upward, and the upward movement of the pressing plate 56 drives the rotating block 513 to rotate. When the pressing plate 56 has risen completely, due to the action of the torsion spring hinged between the rotating block 513 and the oil pressing box 51, the rotating block 513 rotates back to its original position. At this time, the pressing plate 56 stored in the storage box 514 slides into the oil pressing box 51 along the inclined surface of the inner wall of the storage box 514 and the feeding wheel on the inclined surface due to gravity. This process is repeated, with the pad 38 driving the pressing plate 56 to move upward and the rotating block 513 limiting it. This realizes the automatic stacking of oil cakes by the device, reduces the number of times to add stacks during pressing, reduces the labor intensity of workers, and avoids the vacuum leakage of oil cakes caused by the constant application and stopping of pressure on the oil cakes by the pre-pressing mechanism 4 due to excessive stacking, which affects the final oil extraction effect.
