Description

Technical Field

[0001] The present invention relates to the technical field of oil pressing, and particularly relates to an automatic oil pressing production line and its processing technology. Background Art

[0002] The oil pressing production line connects multiple pressing devices and a feeding system through a conveying system. The feeding system can automatically feed the oil pressing carrier. The oil pressing carrier is conveyed to the corresponding pressing device through the conveying system. The pressing device stacks the oil pressing carriers. After the stacking is completed, it is pushed and pressed by a hydraulic mechanism, so as to squeeze out the oil in the oil pressing carrier. After the pressing is completed, the pressing device unloads the oil pressing carriers and outputs them through the conveying system, so as to realize automated production.

[0003] After the output of the conveying system, it is necessary to manually take out the residue cake by operation, send the empty oil pressing carrier back by a trolley, and then manually assemble it to the feeding system one by one to realize the reuse of the oil pressing carrier. However, the oil pressing carrier is provided with numerous oil guiding channels, and there is a large amount of residual oil inside the oil guiding channels. The residual oil is extremely easy to drip during the transfer or flow process, which not only causes waste of oil liquid and reduces the overall oil yield, but also affects the production environment. The contaminated residual oil will also affect the quality of the subsequent production oil liquid and other technical problems. In addition, the oil pressing carrier is heavy. Manually handling the oil pressing carrier not only has low efficiency, but also is prone to bumping, affecting its use. Therefore, improvement is needed. Summary of the Invention

[0004] To overcome the problems existing in the related art, an embodiment of the present invention provides an automatic pressing system to solve the technical problems of high automation degree and high oil yield of the oil liquid.

[0005] According to the first aspect of the embodiment of the present invention, an automatic oil pressing production line is provided, including a feeding system, a feeding system and multiple automatic pressing systems. The multiple automatic pressing systems are spaced apart along the length direction of the feeding system: The feeding system conveys a fixed amount of oil materials to the oil pressing carrier. The fully loaded oil pressing carrier flows through the feeding system to one of the automatic pressing systems; The automatic oil pressing production line further includes a material returning system: The material returning system includes a residual oil recovery device, a cake removing device and a tray recovery device. The residual oil recovery device covers the oil pressing carrier output by the automatic pressing system and conveys a gas with a preset pressure in a specific direction. The residual oil in the oil pressing carrier is discharged from the residual oil recovery device through the pressurized gas; The cake removing device is located in the output direction of the residual oil recovery device. The cake removing device removes the residue cake in the oil pressing carrier, and the tray recovery device conveys the empty oil pressing carriers to the feeding system one by one.

[0006] According to the second aspect of the embodiments of the present invention, there is provided a processing technology for an automatic oil pressing production line, which is applied to the automatic oil pressing production line as described above. The processing technology includes: Controlling the feeding system to perform quantitative feeding on the oil pressing carriers one by one; Controlling the feeding system to receive the loaded oil pressing carriers and transport the oil pressing carriers to the corresponding automatic pressing system; Controlling the automatic pressing system to stack the oil pressing carriers one by one, and performing pressing after stacking a preset number. The pressed oil liquid flows out directionally through a pipeline; Controlling the oil pressing carriers after oil pressing to be unstacked and transported to the feeding system one by one; Controlling the residual oil recovery device to cover the oil pressing carrier and input gas at a preset pressure to drive the oil liquid contained in the oil pressing carrier to discharge; Controlling the cake removing device to turn over the oil pressing carrier and remove the residue cake in the oil pressing carrier; Controlling the tray recovery device to transport the empty oil pressing carriers to the feeding system; Repeating the above steps to form an automatic oil pressing production.

[0007] The technical solutions provided by the embodiments of the present invention may include the following beneficial effects: The residual oil recovery device performs pneumatic drive recovery on the residual oil liquid after pressing the oil pressing carrier, thereby realizing non-contact residual oil cleaning, avoiding the reverse absorption of residual oil by the residue cake, and improving the overall oil yield. The cooperation of the cake removing device and the tray recovery device can discharge the residue cake in the oil pressing carrier and automatically send it back to the feeding system, thereby forming a cyclic automated pressing production with high automation and less manual intervention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of the present invention. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0019] As Figures 1 to 4As shown in the figure, the present invention provides an automatic oil pressing production line, which includes a feeding system 10, a material conveying system 30 and a plurality of automatic pressing systems 20. The plurality of automatic pressing systems 20 are spaced apart along the length direction of the material conveying system 30.

[0020] The feeding system 10 conveys a fixed quantity of oil materials to the oil pressing carrier 50.

[0021] Among them, the feeding system 10 includes a feeding mechanism 11, a material loading mechanism 13 and a jacking mechanism 12 located below the material loading mechanism 13. The feeding mechanism 11 includes a hoist and a silo 131. The hoist can convey the pre-processed oil materials into the silo 131, and the silo 131 can output a fixed quantity of oil, so as to realize the automatic supply and output of the fixed quantity of oil materials.

[0022] The material conveying system 30 passes through the feeding system 10. The material conveying system 30 includes a track assembly 31 and a plurality of pallet racks 32 movable on the track assembly 31. The track assembly 31 is provided with a driving chain, and the plurality of pallet racks 32 are movably mounted on the track assembly 31. Each pallet rack 32 can carry the oil pressing carrier 50 and can drive the pallet rack 32 to move.

[0023] The material loading mechanism 13 includes a material loading station 132 and a material pressing station 133 arranged at intervals. The feeding mechanism 11 is connected to the material loading station 132 for conveying oil materials to the oil pressing carrier 50 corresponding to the material loading station 132. Among them, the material loading station 132 is provided with a first pushing member located below the track assembly 31. The first pushing member pushes the empty oil pressing carrier 50 upward to receive the oil output from the silo 131. After the oil pressing carrier 50 is filled, the first pushing member descends, and the oil pressing carrier 50 is mounted on the track assembly 31 through the pallet rack 32.

[0024] The track assembly 31 drives the pallet rack 32 to move to the material pressing station 133. The material pressing station 133 is provided with a second pushing member located below the track assembly 31 and a cake pressing member located above. The second pushing member pushes the full oil pressing carrier 50 upward, and the cake pressing member protrudes downward to pre-press and flatten the oil materials in the oil pressing carrier 50, so that the loading heights of all the oil pressing carriers 50 are the same. After the oil pressing carrier 50 is pre-pressed, the second pushing member descends, and the oil pressing carrier 50 is mounted on the track assembly 31 through the pallet rack 32 and moves towards the automatic pressing system 20. The second pushing member can be configured as a hydraulic cylinder or a pneumatic cylinder.

[0025] Preferably, the feeding system 10 includes upper cloth stations 14 installed at both ends of the material loading mechanism 13. The upper cloth stations 14 are used to lay the cushion cloth at the bottom of the empty oil pressing carrier 50 and on the top of the oil materials in the pre-pressed oil pressing carrier 50.

[0026] The feeding system 10 automatically transports the oil pressing carriers 50 to multiple automatic pressing systems 20 through the feeding system 30. The fully loaded oil pressing carriers 50 are transferred through the feeding system 30 to one of the automatic pressing systems 20. Each automatic pressing system 20 can load multiple oil pressing carriers 50 and automatically press the oil materials to realize the pressing production of the oil liquid.

[0027] Among them, the automatic pressing system 20 includes a pressing device 22 and a manipulator device 21. The manipulator device 21 is located on one side of the pressing device 22, and the track assembly 31 passes through the manipulator device 21. The manipulator device 21 is provided with a manipulator mechanism 211, and the manipulator mechanism 211 is used to automatically clamp the oil pressing carrier 50 on the track assembly 31 and transport it to the pressing device 22 to realize automatic loading and unloading production.

[0028] Preferably, the track assembly 31 is provided with a positioning mechanism to determine the moving position of the tray rack 32 on the track assembly 31. Optionally, the positioning mechanism can position the loading position of the tray rack 32 relative to the manipulator device 21.

[0029] Define the orientation where the pressing device 22 is located as the front, the orientation where the manipulator device 21 is located as the rear, the gravity direction as the lower side, and the direction away from the gravity direction as the upper side.

[0030] Among them, the manipulator mechanism 211 can move in the front-rear direction and lift in the up-down direction. The manipulator mechanism 211 clamps the oil pressing carrier 50 and moves back and forth to realize the movement of the oil pressing carrier 50 between the pressing device 22 and the track assembly 31. The manipulator mechanism 211 clamps the oil pressing carrier 50 and moves up and down, thereby adjusting the placement height position of the oil pressing carrier 50 to avoid rigid impact of the oil pressing carrier 50 on the pressing device 22 or the tray rack 32. The manipulator device 21 and the pressing device 22 are paired one by one, and can automatically move and transport the oil pressing carrier 50 between the tray rack 32 and the bottom bracket 223, thereby realizing automatic loading and unloading.

[0031] Specifically, the manipulator device 21 includes a mounting frame 212 with a frame structure, a sliding box 213 sliding on the mounting frame 212, and an inner bracket slidably mounted in the sliding box 213. The manipulator mechanism 211 is mounted on the inner bracket and moves up and down with the inner bracket. The sliding box 213 drives the inner bracket and the manipulator mechanism 211 to move back and forth as a whole.

[0032] In one embodiment, two first slide rails are installed on opposite sides of the mounting frame 212, and the sliding box 213 is hung and slid on the first slide rails to form the front-rear movement of the manipulator mechanism 211.

[0033] A second slide rail is installed in the sliding box 213, the inner bracket is slidably mounted on the second slide rail, and the manipulator mechanism 211 is movably mounted on the inner bracket. The second slide rail is perpendicular to the first slide rail, so that the manipulator mechanism 211 can move up and down along the second slide rail.

[0034] The manipulator mechanism 211 closes or expands relatively, so as to actively clamp the oil pressing carrier 50. After the manipulator mechanism 211 clamps the oil pressing carrier 50, it can move back and forth along the first slide rail to move the oil pressing carrier 50 to the tray rack 32 or the bottom bracket 223. After the manipulator mechanism 211 clamps the oil pressing carrier 50, it can move up and down along the second slide rail to drive the oil pressing carrier 50 to be lifted or gently placed. The combined movement of the sliding box 213 on the first slide rail and the second slide rail can realize the automatic loading and unloading of the oil pressing carrier 50.

[0035] The manipulator mechanism 211 automatically clamps the oil pressing carrier 50 on the track assembly 31 and transports it to the pressing device 22 through the adjustment of the front and rear positions and the adjustment of the lifting height. The pressing device 22 includes a stacking device 224, a bottom bracket 223, a jacking device 221 and a top pressing seat 222 which are oppositely arranged. The pressing device includes a plurality of columns 226. The top pressing seat 222 is fixed to the top of the columns 226. The jacking device 221 and the top pressing seat 222 are respectively fixed to the columns 226. The jacking device 221 is fixed to the bottom of the columns 226. The hydraulic mechanism of the jacking device 221 pushes the bottom bracket 223 to move upward. Among them, the jacking device 221 is located at the bottom of the pressing device 22, and the telescopic power part is arranged at the bottom of the device, which can reduce the instability generated by the movement.

[0036] As Figures 4 to 6 shown, the jacking device 221 is connected to the bottom bracket 223. The bottom bracket 223 is slidably connected to the column 226. The bottom bracket 223 is used for placing the oil pressing carrier 50. The jacking device 221 pushes the tray rack 32 towards the top pressing seat 222. The oil liquid generated by pressing is guided and output through the bottom bracket 223. The distance between the stacked oil pressing carriers 50 gradually decreases. The oil liquid of the upper oil pressing carrier 50 enters the oil outlet channel of the next oil pressing carrier 50. The oil liquid of the bottommost oil pressing carrier 50 flows into the tray rack 32 and is then centrally output outwards through the tray rack 32.

[0037] Among them, the bottom bracket 223 is provided with a central boss 2232 and a drainage groove 2231 surrounding the central boss 2232. The central boss 2232 is configured as a disc-shaped structure. The outer diameter of the central boss 2232 is slightly larger than the outer peripheral wall of the oil pressing carrier 50 to shorten the flow path of the oil liquid. The oil pressing carrier 50 is placed on the central boss 2232. The jacking device 221 pushes the bottom bracket 223 to move upward, and the oil liquid of the oil pressing carrier 50 is discharged into the drainage groove 2231.

[0038] The oil is guided and output through the bottom bracket 223, which can collect the oil centrally and reduce the disadvantages of disorderly oil flow. Further, the central boss 2232 is provided with a plurality of concave radiation grooves that radiate and extend from the center of the central boss 2232 to the periphery, so as to guide the oil in the bottom area of the oil press carrier 50 into the drainage groove 2231, and the oil drainage effect is good.

[0039] Further, the pressing device further includes an oil guiding pipeline 225 and an oil guiding frame 2251 installed on the bottom bracket 223. The oil guiding frame 2251 is detachably connected to the bottom bracket 223, and the oil guiding frame 2251 is installed at the outlet of the drainage groove 2231.

[0040] The oil guiding frame 2251 can transfer and guide the oil flow path between the drainage groove 2231 and the oil guiding pipeline 225. Among them, the oil guiding pipeline 225 is provided with a lateral long hole 2252, and the output end of the oil guiding frame 2251 is inserted into the long hole 2252. The length direction of the long hole 2252 is parallel to the sliding direction of the oil guiding frame 2251. The oil guiding frame 2251 moves up and down with the bottom bracket 223, and the oil guiding frame 2251 moves up and down along the long hole 2252 so that the oil can always enter the oil guiding pipeline 225.

[0041] The stacking device 224 is located above the bottom bracket 223 and slides along the column 226. The stacking device 224 stacks a plurality of oil press carriers 50 in sequence. The stacking device 224 automatically stacks the oil press carriers 50 on the bottom bracket 223 one by one or separates the plurality of oil press carriers 50 after pressing one by one, thereby realizing the automatic stacking and unstacking process of the pressing device 22 and realizing automatic operation.

[0042] Among them, the stacking device 224 includes a lower stacking component 2242, an upper stacking component 2241, a connecting frame 2243 and a lifting component 2246 installed on the bottom bracket 223. The connecting frame 2243 is fixedly connected to the upper stacking component 2241 and the bottom bracket 223. The connecting frame 2243, the upper lifting frame and the bottom bracket 223 form a frame structure.

[0043] The output shaft of the lifting component 2246 is connected to the lower stacking component 2242. The lifting component 2246 pushes the lower stacking component 2242 to reciprocate between the upper stacking component 2241 and the bottom bracket 223, and the oil press carrier 50 is alternately clamped by the lower stacking component 2242 and the upper stacking component 2241.

[0044] During the stacking process, the lower palletizing component 2242 clamps the oil press carrier 50 on the bottom bracket 223. The lifting component 2246 pushes the lower palletizing component 2242 upward until the oil press carriers 50 fixed at the upper palletizing component 2241 and the oil press carriers 50 fixed at the lower palletizing component 2242 are stacked. Then, the upper palletizing component 2241 releases the locking of the oil press carrier 50. The lifting component 2246 pushes the lower palletizing component 2242 and multiple oil press carriers 50 upward as a whole until the stacking slots of the lowermost oil press carrier 50 at the stacking position are aligned with the upper palletizing component 2241. Then, the upper palletizing component 2241 is clamped into the stacking slots to lift the stacked multiple oil press carriers 50. The lifting component 2246 drives the lower palletizing component 2242 downward to correspond to the oil press carrier 50 on the bottom bracket 223, and repeats the above steps to complete the stacking process. After the oil pressing is completed, the multiple oil press carriers 50 are unstacked, and the unstacking process is opposite to the above stacking process.

[0045] During the process of the lower palletizing component 2242 and the upper palletizing component 2241 alternately clamping the oil press carrier 50, the lower palletizing component 2242 is provided with a lower locking mechanism 2244, and the upper palletizing component 2241 is provided with an upper locking mechanism 2245. The lower palletizing component 2242 and the upper palletizing component 2241 are complementary and cooperate. The parts of the lower locking mechanism 2244 and the upper locking mechanism 2245 for locking the oil press carrier 50 are at the same height. Among them, the upper locking mechanism 2245 and the lower locking mechanism 2244 are pin structures with telescopic movement.

[0046] The lower palletizing component 2242 includes two groups. The two groups of lower palletizing components 2242 are arranged oppositely and slide on the column 226, forming an open entrance between the two groups of lower palletizing components 2242, which facilitates the oil press carrier 50 to be fed into the area between the two groups of lower palletizing components 2242 from the entrance. There are two lifting components 2246, and each lifting component 2246 is connected to the corresponding lower palletizing component 2242. The two groups of lifting components 2246 are independently arranged and cooperate to lift the oil press carrier 50 together. Preferably, the lifting component 2246 is configured as a hydraulic cylinder.

[0047] The lower palletizing component 2242 further includes a lower lifting frame in the form of a crossbeam structure. The lower lifting frame slides on the column 226 and is connected to the lifting component 2246. The lower locking mechanism 2244 is telescopically and movably installed on the lower lifting frame and is used to clamp the opposite sides of the oil press carrier 50.

[0048] The upper palletizing component 2241 includes an upper lifting frame, and the upper lifting frame is an integral template structure. Two groups of upper locking mechanisms 2245 are arranged oppositely on the upper lifting frame to jointly clamp the oil press carrier 50, and multiple oil press carriers 50 are stacked above the upper locking mechanism 2245.

[0049] The force of the lower locking mechanism 2244 holding up the oil pressing carrier 50 is transmitted to the lower lifting frame, and the force of the upper locking mechanism 2245 holding up the oil pressing carrier 50 is transmitted to the upper lifting frame, so as to avoid excessive pressure on the lower locking mechanism 2244 and the upper locking mechanism 2245 themselves and maintain the flexibility of the telescopic activity.

[0050] like Figures 4 to 6 As shown, the stacking device 224 can independently complete the stacking of the oil pressing vehicle 50 through the lifting component 2246, the lower stacking component 2242 and the upper stacking component 2241, without the participation of a large pressure device, greatly reducing energy consumption and simplifying structural complexity.

[0051] The lower locking mechanism 2244 and the upper locking mechanism 2245 are used to lock the parts of the oil pressing carrier 50 at the same height. Accordingly, a complementary structure is formed between the lower stacking assembly 2242 and the upper stacking assembly 2241, and the lower locking mechanism 2244 and the upper locking mechanism 2245 are at the same height in the complementary area.

[0052] Optionally, the upper lifting frame is provided with an air-avoiding space, and the upper locking mechanisms 2245 are distributed on both sides of the air-avoiding space. The lower lifting frame includes a bracket boss matching the air-avoiding space, and the lower locking mechanism 2244 is installed on the bracket boss. The lower lifting frame is close to or abuts against the upper lifting frame, so that the upper locking mechanism 2245 and the lower locking mechanism 2244 are at the same height, so as to realize the alternating lifting of the oil pressing carrier 50.

[0053] The lower locking mechanism 2244 and the upper locking mechanism 2245 are locked in the same stacking slot position of the oil pressing carrier 50, so as to realize the alternate clamping of the oil pressing carrier 50. The clamping height and position can be precisely controlled, and the moving stroke of the oil pressing carrier 50 can be shortened, which can increase the stacking volume of the oil pressing carrier 50 under the same conditions.

[0054] like Figures 4 to 7 As shown, the oil pressing carrier 50 includes a disc body 51, a stripping assembly 52 and an oil disc bottom plate 53. The disc body 51 is provided with a pressing chamber. Furthermore, the disc body 51 includes a plurality of oil guide channels 512 and a plurality of guide grooves 513. The positioning groove 511 is recessed from the top of the disc body 51. The oil guide channel 512 passes through from the positioning groove 511 toward the assembly step direction of the disc body 51 to form a plurality of channel-shaped holes distributed circumferentially around the disc body 51 to quickly guide out the oil gathered in the positioning groove 511.

[0055] Preferably, the larger the total flow area of ​​the oil guide channel 512 is, the faster the oil guide speed is. Preferably, the plurality of oil guide channels 512 are evenly distributed around the center line of the oil pressing vehicle 50 to form an isotropically balanced conduction path.

[0056] It is worth mentioning that the oil guiding channel 512 can conduct the oil pressing carriers 50 stacked up and down, and the oil overflowing from the self oil pressing carrier 50 can also flow through the oil guiding channel 512 and the diversion groove 513.

[0057] The step surface of the assembly step partially protrudes to form a positioning rib 515, and the oil guiding channel 512 connects the positioning groove 511 and the positioning rib 515. The positioning rib 515 is a gradually shrinking convex structure. Preferably, the positioning rib 515 is set as a triangular protrusion, a curved surface protrusion or a hemispherical protrusion. The end of the positioning rib 515 has a small size, which can guide the oil to flow towards the outer peripheral wall surface of the small end of the assembly step and change the liquid flow direction.

[0058] Furthermore, the positioning rib 515 is provided with an outer conical surface, and the positioning groove 511 is provided with a matching inner conical surface. The cone angle of the outer conical surface is the same as the cone angle of the inner conical surface. The outer conical surface and the inner conical surface are complementary conical surface structures. When the outer conical surface and the inner conical surface are closed, a sealing surface of two adjacent oil pressing carriers 50 is formed, forming a channel space with a closed outer edge and a circular flow of internal oil.

[0059] In a preferred embodiment, there is a height difference between the two sides of the positioning groove 511. Among them, the height of the inner groove wall of the positioning groove 511 is less than the height of the outer groove wall of the positioning groove 511 to block the outward flow of oil and keep the oil flowing out through the oil guiding channel 512.

[0060] Furthermore, a plurality of notch grooves 514 are arranged at intervals on the inner groove wall of the positioning groove 511. The plurality of notch grooves 514 connect the positioning groove 511 and the pressing cavity, so that a part of the oil pressed out of the oil material can enter the positioning groove 511 through the notch grooves 514, and then the oil is output directionally through the oil guiding channel 512. At the same time, the notch grooves 514 can further reduce the risk of oil output from the outer groove wall of the positioning groove 511. Optionally, the notch grooves 514 are arranged at intervals around the center line of the oil pressing carrier 50. For example, the number of notch grooves 514 can be set to more than one.

[0061] The sieve plate 54 is inserted and connected to the corresponding diversion groove 513, and a plurality of oil passing sieve holes are uniformly distributed on the sieve plate 54. The sieve plate 54 filters the oil through the oil passing sieve holes to prevent the slag from entering the diversion groove 513 and achieve the filtering effect.

[0062] Furthermore, the diversion groove 513 is concave in the pressing cavity and penetrates to the assembly step on one side; multiple diversion grooves 513 can quickly discharge the oil in the oil pressing cavity laterally. During the pressing process, the oil can directly flow into the lower side of the assembly step through the diversion groove 513, so as to realize multi-channel oil output in combination with the oil guiding channel 512. Moreover, all the oil converges at the positioning groove 511 of the next oil pressing carrier 50, realizing secondary balanced flow and greatly improving the flow efficiency.

[0063] Among them, the blanking assembly 52 includes a blanking plate 521 and a guide post mechanism 522 fixedly connected to the blanking plate 521. The blanking plate 521 is adapted to the shape of the pressing cavity and is laid at the bottom of the pressing cavity. The guide post mechanism 522 slides in the blanking hole to drive the blanking plate 521 to slide along the pressing cavity without detaching the blanking plate 521 from the disk body 51.

[0064] The oil pan bottom plate 53 is detachably connected to the bottom of the disk body 51 through fasteners. During the stacking and oil pressing process of multiple oil pressing carriers 50, a part of the upper oil pressing carrier 50 is inserted into the pressing cavity of the next oil pressing carrier 50, and there is a diameter difference in the inserted and matched part, thus forming an overflow space. The oil pan bottom plate 53 moves towards the blanking plate 521 in the pressing cavity. Both the oil pan bottom plate 53 and the blanking plate 521 are provided with mesh holes, which can filter and output the oil without introducing the oil raw materials, improving the purity of the oil.

[0065] To improve the flow efficiency of the oil, the blanking plate 521 is provided with a concave diversion mesh groove, thus forming a network-type flow channel, which not only expands the flow area, but also forms an overhead structure, maintaining the support effect and having high bending and torsion resistance.

[0066] Preferably, the structure of the oil pan bottom plate 53 is basically the same as that of the blanking plate 521. The oil pan bottom plate 53 is provided with a diversion mesh groove and a plurality of mesh holes. The difference is that the oil pan bottom plate 53 is provided with clearance holes surrounding the blanking hole.

[0067] Such as Figure 1 、 Figure 4 and Figure 8 As shown, after the automatic pressing system 20 finishes the pressing process, each oil pressing carrier 50 that has completed pressing is sent into the feeding system 30 one by one, and the feeding system 30 sends the oil pressing carrier 50 that has completed pressing into the return material system 40.

[0068] The return material system 40 includes a residual oil recovery device 41, a cake removing device 42, and a tray recovery device 43. The residual oil recovery device 41 covers the oil pressing carrier 50 output by the automatic pressing system 20 and directs the conveyance of gas at a preset pressure. The residual oil in the oil pressing carrier 50 is discharged from the residual oil recovery device 41 through the pressurized gas. The residual oil recovery device 41 performs pneumatic drive recovery on the residual oil remaining after pressing the oil pressing carrier 50, thereby realizing non-contact cleaning of residual oil, avoiding the reverse absorption of residual oil by the cake, and improving the overall oil yield.

[0069] The cake removing device 42 is located in the output direction of the residual oil recovery device 41. The cake removing device 42 removes the cake in the oil pressing carrier 50, and the tray recovery device 43 conveys the empty oil pressing carriers 50 to the feeding system 10 one by one. The cooperation of the cake removing device 42 and the tray recovery device 43 can discharge the cake in the oil pressing carrier 50 and automatically send it back to the feeding system 10, thereby forming a cyclic automated pressing production with high automation and less manual intervention.

[0070] Furthermore, the tray rack 32 includes a concave limiting groove 321 and an oil drainage channel 323 located in the limiting groove 321. The limiting groove 321 is used to limit the oil pressing carrier 50, and the oil drainage channel 323 discharges the oil in the limiting groove 321. The limiting groove 321 is a concave structure, which can limit the oil pressing carrier 50 and accommodate the flow of the oil pressing carrier 50. The oil drainage channel 323 is connected to the limiting groove 321 to direct the oil out.

[0071] Preferably, the residual oil recovery device 41 includes a lifting mechanism 411 and an oil return cover 412 connected to the lifting mechanism 411. The oil return cover 412 is a cover structure with its opening facing downward. After the oil pressing carrier 50 and the tray rack 32 that have completed pressing move to the lower part of the oil return cover 412, the lifting mechanism 411 drives the oil return cover 412 to move downward, and the oil return cover 412 movably covers the oil pressing carrier 50 on the tray rack 32, and the contact between the oil return cover 412 and the tray rack 32 is approximately sealed.

[0072] The oil return cover 412 is connected with an air inlet channel and an oil outlet channel. The air inlet channel conveys pressurized gas, and the residual oil contained in each oil outlet channel and other parts of the oil pressing carrier 50 is discharged under the action of air pressure and enters the limiting groove 321, and then enters the oil outlet channel through the oil drainage channel 323. The air inlet channel centrally inputs the gas with pressure, and the pressure of the oil outlet channel is small. Correspondingly, the residual oil can enter the oil outlet channel along the oil drainage channel 323, and then be guided to the oil storage container along the oil outlet channel. Preferably, the tray rack 32 is provided with a gas guiding channel 322, and the gas guiding channel 322 corresponds to the air inlet channel.

[0073] After the residual oil in the oil press vehicle 50 is cleaned up, the cake removing device 42 needs to take out the residue cake from the oil press vehicle 50 to separate the oil press vehicle 50 from the residue cake, and the oil press vehicle 50 is reused in the next round. Among them, the cake removing device 42 includes a cake removing machine frame 423, a pushing mechanism 422 and a flipping mechanism 421. The pushing mechanism 422 is located below the flipping mechanism 421, and the flipping mechanism 421 is located above.

[0074] The track assembly 31 passes through the cake removing machine frame 423. Among them, when the cake removing device 42 performs the cake removing operation, the pushing mechanism 422 pushes the tray rack 32 to move upward in the direction of the flipping mechanism 421, and the tray rack 32 disengages from the track assembly 31. When the oil press vehicle 50 reaches the clamping area of the flipping mechanism 421, the flipping mechanism 421 clamps and flips the oil press vehicle 50. Among them, when the oil press vehicle 50 is flipped forward and the opening of the oil press vehicle 50 faces downward, the residue cake separates from the oil press vehicle 50 and moves away from the track assembly 31. After that, when the oil press vehicle 50 is flipped backward and reset and the opening of the oil press vehicle 50 faces upward, the pushing mechanism 422 pushes the tray rack 32 to move and lift the oil press vehicle 50 downward, so that the empty oil press vehicle 50 returns to the track assembly 31.

[0075] The pushing mechanism 422 pushes the tray rack 32 to move between the flipping mechanism 421 and the track assembly 31, and the flipping mechanism 421 clamps and flips the oil press vehicle 50, which can realize the unloading of the residue cake of the oil press vehicle 50.

[0076] Preferably, the flipping mechanism 421 includes a sliding frame and a flipping frame installed on the sliding frame. The flipping frame is used to clamp and fix the oil press vehicle 50. The flipping frame can be driven by a motor mechanism to flip so as to realize rotation. The sliding frame can drive the flipping frame to slide along the cake removing machine frame 423, so as to realize flipping and cake removal at different positions and improve the flexibility of cake removal.

[0077] The automatic oil press production line disclosed in the above embodiment is processed, and its processing technology includes: Controlling the feeding system 10 to feed the oil press vehicle 50 one by one in a quantitative manner. The feeding system 10 performs quantitative transportation through the metering mechanism of the silo 131 to keep the oil contained in the oil press vehicle 50 basically consistent.

[0078] Controlling the feeding system 30 to receive the loaded oil press vehicle 50 and transport the oil press vehicle 50 to the corresponding automatic pressing system 20. The feeding system 30 transports the oil press vehicle 50. Among them, each automatic pressing system 20 is provided with a position sensing or limiting mechanism to ensure that the oil press vehicle 50 can be transported according to the built-in program.

[0079] Control the automatic pressing system 20 to stack the oil pressing carriers 50 one by one, and perform pressing after stacking a preset quantity. The oil pressed out flows out directionally through the pipeline. Each automatic pressing system 20 can stack multiple oil pressing carriers 50 for pressing, with high oil pressing efficiency and large oil pressing capacity. Among them, the stacking process and the unstacking process can refer to the processes disclosed in the above embodiments.

[0080] Control the oil pressing carriers 50 that have completed oil pressing to be unstacked and conveyed to the feeding system 30 one by one.

[0081] Control the residual oil recovery device 41 to cover the oil pressing carrier 50 and input gas at a preset pressure to drive the oil contained in the oil pressing carrier 50 to be discharged. The residual oil recovery device 41 performs residual oil air pressure discharge on the oil pressing carriers 50 that have completed pressing on the feeding system 30, thereby realizing oil recovery, which can not only avoid oil pollution and waste, but also prevent the oil from being sucked back by the residue cake, improving the overall oil yield.

[0082] Control the cake removing device 42 to turn over the oil pressing carrier 50 and remove the residue cake in the oil pressing carrier 50.

[0083] Control the pallet recycling device 43 to convey the empty oil pressing carriers 50 to the feeding system 10.
