Description

Technical Field

[0001] This invention belongs to the field of pre-pressed cakes, specifically relating to a multi-station pre-pressed cake device for traditional pressing methods. Background Technology

[0002] Traditional oil pressing methods use single-station wooden or stone molds for manual pre-pressing, which has significant drawbacks: First, the production efficiency is extremely low, as the processes of feeding, loading the mold, applying pressure, and demolding all need to be carried out sequentially, resulting in high labor intensity and long processing time; second, the pre-pressing quality is unstable, relying entirely on the experience and physical strength of the craftsmen, and the unevenness of the cake can easily affect the subsequent oil yield and oil quality.

[0003] Patent CN210215283U discloses a pretreatment pressing device for soybean oil refining. This patent includes a frame, a pressing chamber, a screw press shaft, and a pressing motor. A feed cylinder is connected to the feed end of the pressing chamber, and a feed hopper is connected to the feed cylinder. A feed shaft is installed inside the feed hopper. The screw press shaft and the feed shaft are respectively connected to the pressing motor. The pressing chamber is provided with an oil outlet and a slag outlet for discharging the pressed cake. A guide plate is inclinedly arranged at the slag outlet, and an auxiliary slag discharge mechanism is provided on one side of the guide plate. The auxiliary slag discharge mechanism includes a slag discharge motor, a drive gear, a driven gear, a connecting rod, and a swing rod for agitating the pressed cake. The swing rod is located above the slag guide plate and is set parallel to the slag guide plate. The output shaft of the slag discharge motor is connected to the drive gear. The drive gear meshes with the driven gear. One end of the connecting rod is fixed to the end face of the driven gear, and the other end of the connecting rod is hinged to the swing rod. The swing rod is set at the slag outlet to move the press cake and prevent the press cake from accumulating at the slag outlet.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by pushing the axial plate upward, the oil is squeezed from the upper and lower sides, so that the oil is pre-pressed into a cake.

After falling into the receiving frame, the oil rolls down the inclined surfaces on both sides into the middle of the frame, improving the ease of recycling. The scraper contacts the inner wall of the receiving frame and pushes the oil to the discharge port in the middle of the frame, further enhancing the ease of recycling. The scraper can then scrape off the oil adhering to its inner wall, preventing oil accumulation from affecting the recycling effect. The elastic return function of the elastic telescopic rod keeps the scraper in contact with the inner surface of the receiving frame, further improving the scraping effect. The scraper pushes the oil gathered on the surface of the receiving plate into the receiving frame, making the recycling of excess oil completely automated and improving the ease of use of the device. The pull plate drives the L-shaped clamp to rotate and unfold, and then the scraper and clamp are quickly pulled away from the clamp seat for easy cleaning, further improving the ease of use of the device. The radial pusher moves forward and pushes the cake forward, causing the bottom surface of the cake to detach from the axial pusher, thus enabling the cake to be demolded quickly without the need for complicated manual demolding work, improving the overall pre-pressing efficiency. The spade rotates at a certain angle along the central axis and inserts between the cake and the axial pusher, quickly separating the two and preventing the cake from completely sticking to the upper surface of the axial pusher, thus improving the demolding effect and the integrity of the cake. The rotating arm rotates and resets due to the torsion spring at its hinge with the central axis, and drives the spade to reset, facilitating the next demolding. Attached Figure Description

[0018] 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.

[0019] like Figure 1-8As shown, one embodiment of the present invention is: a multi-station pre-pressing cake device for traditional pressing, including a support 1, a fixed bracket 2 fixedly connected to the upper surface of the support 1, a pre-pressing machine 3 fixedly connected to the right upper surface of the fixed bracket 2, an upper pressing mold 4 fixedly connected to the bottom free end of the pre-pressing machine 3, a weighing frame 5 snapped onto the left inner surface of the fixed bracket 2, a conveyor 6 arranged on the left side of the support 1, a lower mold plate 7 slidably connected to the inner surface of the support 1, a residual material recycling device 8 arranged below the fixed bracket 2, the residual material recycling device 8 being used to recycle excess oil generated before a single pre-pressing, and a demolding device 9 being provided. Placed above support 1, demolding device 9 is used to demold the pre-pressed cake. Axial push plate 12 rises and squeezes the oil from both sides, so that the oil is pre-pressed into a cake. Pressure plate 17 transmits pressure to weighing device 18, which can detect the weight of the oil in weighing frame 5, improve the feeding accuracy, accurately control the thickness of each cake, and improve the pre-pressing quality. Support 1 includes linear motor 10, which is fixedly connected to the front and rear sides of the inner wall of support 1. Linear motor 10 is used to drive lower mold plate 7. Cylinder 11 is fixedly connected to the lower surface of lower mold plate 7. The top free end of cylinder 11 The support 1 includes a fixed axial push plate 12, a guide frame 13 fixedly connected to the left side of the support 1, a movable bracket 14 slidably connected to the inner surface of the guide frame 13, casters 15 rotatably connected to the bottom of the movable bracket 14, a limiting plate 16 fixedly connected to the upper left side of the fixed support 2, the limiting plate 16 being used for fixing and limiting the symmetrical material frame 5, a pressure plate 17 fixedly connected to both sides of the weighing frame 5, a weighing device 18 fixedly connected to the upper surface of the fixed support 2, the weighing device 18 being used for weighing the oil on the inner wall of the symmetrical material frame 5, a lifting rod 19 fixedly connected to the front and rear sides of the weighing frame 5, and a lower mold plate 7. The linear motor 10 is fixedly connected to its free end. The axial push plate 12 is slidably connected to the inner surface of the lower mold plate 7. The movable bracket 14 is fixedly connected to the lower surface of the conveyor 6. The weighing frame 5 and the inner surface of the limiting plate 16 abut against each other. The lower surface of the pressure plate 17 abuts against the top of the weighing device 18. The weighing frame 5 is pulled out from between the limiting plates 16 to facilitate the collection and cleaning of residual oil inside. Conversely, the weighing frame 5 is inserted between the limiting plates 16 for easy installation, which improves the ease of operation of the device. After the movable bracket 14 drives the conveyor 6 away from the weighing frame 5, it is convenient to disassemble the symmetrical weighing frame 5, which further improves the ease of operation of the device.

[0020] Working principle: The oil is conveyed to the weighing frame 5 by the conveyor 6. After the oil is conveyed, the valve at the bottom of the weighing frame 5 is opened, and the oil falls from the bottom of the weighing frame 5 onto the axial push plate 12 in the lower mold plate 7. The valve is then closed, and the linear motor 10 is started. The linear motor 10 drives the lower mold plate 7 to slide from left to right in the support 1. After the lower mold plate 7 moves directly below the upper pressure mold 4, the pre-pressing machine 3 and cylinder 11 are started. The pre-pressing machine 3 drives the upper pressure mold 4 to descend and insert into the lower mold plate 7, and the cylinder 11 drives the axial push plate 12 to rise, thereby squeezing the oil from both the top and bottom sides, so that the oil is pre-pressed into a cake. After the oil falls into the weighing frame 5, the weighing frame 5 sinks due to gravity. During the sinking process, the pressure plate 17 descends. When the pressure plate 17 contacts the weighing device 18, its pressure is transmitted to the weighing device 18. 8. After being pressed, the weighing device 18 detects the weight of the oil in the weighing frame 5, improving the feeding accuracy, precisely controlling the thickness of each cake, and improving the pre-pressing quality. After the work is completed, the weighing frame 5 is pulled out from between the fixed bracket 2 and the limiting plate 16 to facilitate the collection and cleaning of the residual oil inside. Conversely, inserting the weighing frame 5 between the limiting plates 16 improves the installation efficiency and promotes the ease of operation of the device. When it is necessary to disassemble the weighing frame 5, the movable bracket 14 is pulled to the left. The movable bracket 14 slides to the left in the guide frame 13 and drives the conveyor 6 and the caster 15 to move to the left. The caster 15 rolls by friction with the ground, which facilitates the adjustment of the movable bracket 14. When the movable bracket 14 drives the conveyor 6 away from the weighing frame 5, it is convenient to disassemble the weighing frame 5, further improving the ease of operation of the device.

[0021] like Figure 1-8As shown, in another embodiment of the present invention, based on the above embodiments, the waste material recovery device 8 includes a receiving frame 81, which is fixedly connected to the lower surface of the top of the support 1. The receiving frame 81 is used to recover excess oil. An elastic telescopic rod 82 is fixedly connected to the inner surfaces of both sides of the lower mold plate 7. A scraper 83 is fixedly connected to the free end of the bottom of the elastic telescopic rod 82. When excess oil overflows from the weighing frame 5, it gathers on the receiving plate 84, preventing excess oil from falling outside the device and causing pollution and waste. The oil then falls from the receiving plate 84 into the receiving frame 81 for subsequent processing. The device improves environmental performance and post-processing efficiency. After the oil falls into the receiving frame 81, it rolls down the inclined surfaces on both sides to the middle of the receiving frame 81, improving recycling convenience. The scraper 83 contacts the inner wall of the receiving frame 81 and pushes the oil to the discharge port in the middle of the receiving frame 81, further improving recycling convenience. The residual material recycling device 8 also includes a receiving plate 84, which is fixedly connected to the upper surface of the lower mold plate 7. The receiving plate 84 is used to prevent oil from falling outside the device. The clamp 85 is fixedly connected to the front and rear sides of the upper surface of the support 1. The side of the clamp 85 away from the receiving plate 84 A protrusion 88 is fixedly connected, and an L-shaped clamping plate 89 is hinged to both sides of the protrusion 88. A pull plate 810 is fixedly connected to the top of the L-shaped clamping plate 89 and snaps into the inner surface of the clamping seat 85. A scraper 87 is fixedly connected to one end of the clamping plate 86 near the receiving plate 84. The scraper 87 is slidably connected to the inner wall of the receiving frame 81, and the lower surface of the receiving plate 84 is slidably connected to the upper surface of the support 1. A torsion spring is provided at the hinge point between the L-shaped clamping plate 89 and the protrusion 88. The inner surface of the L-shaped clamping plate 89 abuts against the side surface of the clamping seat 85, the scraper 87 abuts against the upper surface of the receiving plate 84, and the scraper 83 contacts the inner wall of the receiving frame 81. The scraper can then scrape off the oil adhering to its inner wall, preventing oil accumulation from affecting the recycling effect. The elastic resetting action of the elastic telescopic rod 82 keeps the scraper 83 in contact with the inner surface of the receiving frame 81, further improving the scraping effect. The scraper 87 pushes the oil gathered on the upper surface of the receiving plate 84 into the receiving frame 81, making the recycling of excess oil completely automated and improving the ease of use of the device. The pull plate 810 drives the L-shaped clamp 89 to rotate and unfold, and then the scraper 87 and the clamp 86 are quickly pulled away from the clamp seat 85 for easy cleaning, further improving the ease of use of the device.

[0022] Working principle: When excess oil overflows from the weighing frame 5, it collects on the receiving plate 84, preventing excess oil from falling outside the device and causing pollution and waste. During the movement of the receiving plate 84, the oil falls from its upper surface into the receiving frame 81 for recycling, facilitating subsequent processing and improving the device's environmental performance and post-processing efficiency. After falling into the receiving frame 81, the oil contacts its inner inclined surfaces on both sides and rolls down along the inclined surfaces to the middle of the receiving frame 81, improving recycling convenience. The lower mold plate 7 moves left and right, driving the spring... The elastic telescopic rod 82 moves left and right, which in turn drives the scraper 83 to move left and right. The scraper 83 contacts the inner surface of the receiving frame 81 and generates friction, thereby pushing the oil to the discharge port in the middle of the receiving frame 81, further improving the convenience of recycling. After the scraper 83 contacts the inner wall of the receiving frame 81, it can scrape off the oil adhering to its inner surface, preventing oil accumulation from affecting the recycling effect. When the scraper 83 contacts the inner inclined surfaces on both sides of the receiving frame 81, it is guided by the inclined surfaces to shift upwards, thereby squeezing the elastic telescopic rod. As the rod 82 retracts upwards, and the scraper 83 moves away from the inclined plane, the elastic restoring action of the elastic telescopic rod 82 causes it to descend, ensuring that the scraper 83 remains in contact with the inner surface of the receiving frame 81, further improving the scraping effect. When the lower mold plate 7 moves left and right, it causes the receiving plate 84 to move left and right. When the receiving plate 84 passes below the scraper 87, its upper surface rubs against the bottom end of the scraper 87. The scraper 87 pushes the oil accumulated on the upper surface of the receiving plate 84 into the receiving frame 81, making the recovery of excess oil completely automated and improving efficiency. To improve the ease of use of the device, the scraper 87 is inserted into the clamp 85 through the clamping plate 86, and then the pull plate 810 is released. At this time, the L-shaped clamping plate 89 rotates back to its original position due to the torsion spring at its hinge with the protrusion 88 and fits against the clamp 85, thereby clamping the clamping plate 86 and fixing the scraper 87. Conversely, pulling the pull plate 810 causes the L-shaped clamping plate 89 to rotate and unfold, allowing the scraper 87 and the clamping plate 86 to be quickly removed from the clamp 85 for easy cleaning, further improving the ease of use of the device.

[0023] like Figure 1-8As shown, in another embodiment of the present invention, based on the above embodiments, the demolding device 9 includes a fixed base 91, which is fixedly connected to the rear side of the support 1. A cylinder 92 is fixedly connected to the top of the fixed base 91, and a radial push plate 93 is fixedly connected to the free end of the front side of the cylinder 92. A slot 94 is opened at the bottom rear side of the scraper 87. The radial push plate 93 moves forward and pushes the cake forward, so that the bottom surface of the cake is separated from the axial push plate 12, thereby enabling the cake to be demolded quickly without the need for complicated manual demolding work, thus improving the overall pre-pressing efficiency. The demolding device 9 also includes a push block 95, which is fixedly connected to the upper surface of the receiving plate 84. A central shaft 96 is fixedly connected to the upper surface of the support 1. The circumference of the central shaft 96 is... A rotating arm 97 is hinged to the surface. A shovel plate 98 is fixedly connected to the end of the rotating arm 97 away from the central shaft 96. A rotating rod 99 is fixedly connected to the side surface of the rotating arm 97. A torsion spring is provided at the hinge point between the rotating arm 97 and the central shaft 96. A through groove is provided on the inner side of the shovel plate 98. The left end of the push block 95 abuts against the side surface of the rotating rod 99. The lower surface of the shovel plate 98 abuts against the upper surface of the receiving plate 84. The shovel plate 98 rotates at a certain angle along the axis of the central shaft 96 and inserts between the cake and the axial push plate 12, quickly separating the two and preventing the cake from completely sticking to the upper surface of the axial push plate 12, thus improving the demolding effect and the integrity of the cake. The rotating arm 97 is rotated and reset by the torsion spring at its hinge point with the central shaft 96, which in turn drives the shovel plate 98 to reset, facilitating the next demolding.

[0024] Working principle: After the upper die 4 pre-presses the oil into a cake, the linear motor 10 drives the lower die plate 7 to move to the left and reset. At this time, cylinder 11 is activated. The free end of cylinder 11 extends upward and drives the axial push plate 12 to move upward out of the lower die plate 7. The axial push plate 12 pushes out the cake that is stuck in the lower die plate 7 after being pressed. Then, cylinder 92 on the fixed base 91 is activated. The free end of cylinder 92 extends and drives the radial push plate 93 to move forward and push the cake forward, so that the bottom surface of the cake is separated from the axial push plate 12, thereby making the cake quickly demolded without the need for complicated manual demolding work, improving the overall pre-pressing efficiency. When the receiving plate 84 moves to the left, it drives the push block 95 to move to the left. Moving to the left, the left end of the push block 95 contacts the rotating rod 99 and pushes it to rotate counterclockwise by a certain angle. The rotating rod 99 then drives the shovel plate 98 to rotate along the axis of the central shaft 96 by the rotating arm 97 and inserts it between the cake and the axial push plate 12, quickly separating the two and preventing the cake from completely sticking to the upper surface of the axial push plate 12, thus improving the demolding effect and the integrity of the cake. After the radial push plate 93 pushes the cake out of the device, the next round of pre-pressing is carried out. At this time, the receiving plate 84 drives the push block 95 to move to the right, causing the rotating rod 99 to lose its limit. The rotating arm 97 is affected by the torsion spring at its hinge with the central shaft 96 and rotates back to reset, driving the shovel plate 98 to reset, thus facilitating the next demolding.
