This 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 attached 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.

[0026] As Figures 1 to 3 shown, the present invention provides an automatic pressing system, which includes a pressing device 10, a track device 40, a feeding device 20 and an oil pressing carrier 30. The feeding device 20 is located on one side of the pressing device 10 and can automatically clamp the oil pressing carrier 30 and transport it to the pressing device 10 to realize the loading and unloading production. The track device 40 passes through the feeding device 20, and the track device 40 can continuously transport the oil pressing carrier 30 and cooperate with the feeding device 20 to realize continuous processing.

[0027] Among them, the track device 40 includes a conveying guide rail 42 and a tray rack 41 that slides on the conveying guide rail 42. The tray rack 41 carries the oil pressing carrier 30 and moves along the conveying guide rail 42, so as to send out or send the oil pressing carrier 30 into the feeding device 20. Preferably, the track device 40 is provided with a positioning mechanism to determine the moving position of the tray rack 41. For example, the positioning mechanism can position the loading position of the tray rack 41 relative to the feeding device 20.

[0028] The feeding device 20 is provided with a manipulator mechanism 23, and the manipulator mechanism 23 is used to actively pick up and place the oil pressing carrier 30 on the pallet rack 41. Define the orientation where the pressing device 10 is located as the front, the orientation where the feeding device 20 is located as the rear, the direction of gravity as the lower side, and the direction away from the gravity direction as the upper side.

[0029] Among them, the manipulator mechanism 23 can move in the front-rear direction to clamp and move the oil pressing carrier 30 back and forth, so as to realize the movement of the oil pressing carrier 30 between the pressing device 10 and the track device 40. The manipulator mechanism 23 can move up and down in the vertical direction, so as to adjust the height position of the oil pressing carrier 30 and reduce the impact of the oil pressing carrier 30 on the pressing device 10 or the pallet rack 41. The feeding device 20 and the pressing device 10 are paired one by one, and can automatically move and transport the oil pressing carrier 30 between the pallet rack 41 and the bottom bracket 12, so as to realize automatic loading and unloading.

[0030] The pressing device 10 includes a stacking device 11, a bottom bracket 12, a lifting device 13 and a top pressing seat 14 arranged oppositely, and the oil pressing device includes at least three columns 15. Optionally, the columns 15 can be set to three, then it is a triangular distribution mechanism; the columns 15 are set to four, then it is a quadrangular distribution structure. The top pressing seat 14 is fixed on the top of the column 15, the lifting device 13 and the top pressing seat 14 are respectively fixed on the column 15, the lifting device 13 is fixed at the bottom of the column 15, and the hydraulic mechanism of the lifting device 13 pushes the bottom bracket 12 to move upward. Among them, the lifting device 13 is located at the bottom of the pressing device 10, which can reduce the overall center of gravity.

[0031] The lifting device 13 is connected to the bottom bracket 12, and the bottom bracket 12 is slidably connected to the column 15 to form a bottom support platform on which the oil pressing carrier 30 can be placed. The stacking device 11 is integrally slidably installed on the column 15, and the stacking device 11 moves between the bottom bracket 12 and the top pressing seat 14. The stacking device 11 stacks a plurality of oil pressing carriers 30 in sequence. Among them, the outer shape of the oil pressing carrier 30 is a stepped structure, and the small end of the upper oil pressing carrier 30 is inserted into the opening of the next oil pressing carrier 30, so as to form a superposition and the oil guiding channel 312 is communicated.

[0032] The lifting device 13 pushes the pallet rack 41 to move towards the top pressing seat 14, and the oil liquid generated by pressing is guided and output through the bottom bracket 12. The distance between the stacked oil pressing carriers 30 gradually decreases, and the oil liquid of the upper oil pressing carrier 30 enters the oil outlet channel of the next oil pressing carrier 30. The oil liquid of the bottommost oil pressing carrier 30 flows into the pallet rack 41, and then is centrally output outward through the pallet rack 41. The oil liquid is guided and output through the bottom bracket 12, which can centrally collect the oil liquid and reduce the disadvantages of disordered oil liquid flow.

[0033] The stacking device 11 automatically stacks the oil press carriers 30 on the bottom bracket 12 one by one or separates multiple oil press carriers 30 that have completed pressing one by one, thereby realizing the pressing process of the pressing device 10 and achieving an automated pressing operation.

[0034] The stacking device 11 includes a lower stacking component 111, an upper stacking component 112, a connecting frame 113, and a lifting component 114 installed on the bottom bracket 12. The connecting frame 113 is fixedly connected to the upper stacking component 112 and the bottom bracket 12, and the output shaft of the lifting component 114 is connected to the lower stacking component 111. The connecting frame 113, the upper lifting frame 1122, and the bottom bracket 12 form a frame structure with high overall rigidity strength.

[0035] The lifting component 114 pushes the lower stacking component 111 to reciprocate between the upper stacking component 112 and the bottom bracket 12, and the oil press carrier 30 is alternately clamped by the lower stacking component 111 and the upper stacking component 112. The stacking device 11 is used for stacking multiple oil press carriers 30, and a stacking groove 315 that is concave and stepped or grooved is provided on the outer peripheral wall of the oil press carrier 30.

[0036] During the stacking process, the lower stacking component 111 clamps the oil press carrier 30 on the bottom bracket 12, and the lifting component 114 pushes the lower stacking component 111 to move upward until the oil press carrier 30 fixed at the upper stacking component 112 and the oil press carrier 30 fixed at the lower stacking component 111 are stacked. Then, the upper stacking component 112 releases the locking of the oil press carrier 30. The lifting component 114 pushes the lower stacking component 111 and multiple oil press carriers 30 to move upward as a whole until the stacking groove 315 of the lowermost oil press carrier 30 at the stacking position is aligned with the upper stacking component 112. Then, the upper stacking component 112 is clamped into the stacking groove 315 to lift the stacked multiple oil press carriers 30. The lifting component 114 drives the lower stacking component 111 to move downward to correspond to the oil press carrier 30 on the bottom bracket 12, and repeats the above steps to complete the stacking process. After the pressing is completed, the multiple oil press carriers 30 are unstacked, and the unstacking process is opposite to the above stacking process.

[0037] As Figures 1 to 4 shown, during the process of alternately clamping the oil press carrier 30 by the lower stacking component 111 and the upper stacking component 112, the lower stacking component 111 is provided with a lower locking mechanism 1113, and the upper stacking component 112 is provided with an upper locking mechanism 1123. The lower stacking component 111 and the upper stacking component 112 are complementary, and the parts of the lower locking mechanism 1113 and the upper locking mechanism 1123 for locking the oil press carrier 30 are at the same height.

[0038] The lower palletizing assembly 111 includes two groups. The two groups of lower palletizing assemblies 111 are arranged oppositely and slide on the vertical column 15. An open entrance is formed between the two groups of lower palletizing assemblies 111, facilitating the oil press carrier 30 to be fed into the area between the two groups of lower palletizing assemblies 111 from the entrance. There are two lifting assemblies 114, and each lifting assembly 114 is connected to the corresponding lower palletizing assembly 111. The two groups of lifting assemblies 114 are independently arranged and cooperate to jointly lift the oil press carrier 30. Preferably, the lifting assembly 114 is configured as a hydraulic cylinder.

[0039] The lower palletizing assembly 111 includes a lower lifting frame 1112 and a lower locking mechanism 1113. The lower lifting frame 1112 slides on the vertical column 15. The lower lifting frame 1112 has a crossbeam structure and is connected to the lifting assembly 114. The lower locking mechanism 1113 is telescopically and movably installed on the lower lifting frame 1112 for clamping the opposite sides of the oil press carrier 30.

[0040] The upper palletizing assembly 112 includes an upper lifting frame 1122 and two groups of upper locking mechanisms 1123 arranged oppositely. The upper lifting frame 1122 is an integral template structure. The two groups of upper locking mechanisms 1123 are arranged oppositely to jointly clamp the oil press carrier 30, and multiple oil press carriers 30 are stacked above the upper locking mechanism 1123.

[0041] The force for lifting the oil press carrier 30 by the lower locking mechanism 1113 is transmitted to the lower lifting frame 1112, and the force for lifting the oil press carrier 30 by the upper locking mechanism 1123 is transmitted to the upper lifting frame 1122, avoiding excessive pressure on the lower locking mechanism 1113 and the upper locking mechanism 1123 itself and maintaining the flexibility of telescopic movement.

[0042] The stacking device 11 can independently complete the palletizing of the oil press carrier 30 through the lifting assembly 114, the lower palletizing assembly 111 and the upper palletizing assembly 112, without the participation of a large-scale pressure device, greatly reducing energy consumption and simplifying the structural complexity. The lower locking mechanism 1113 and the upper locking mechanism 1123 can be locked at the palletizing groove 315 positions at different heights of the oil press carrier 30 to achieve staggered and alternating clamping, and then realize the stacking and unloading processes of the oil press carrier 30.

[0043] The parts of the lower locking mechanism 1113 and the upper locking mechanism 1123 for locking the oil press carrier 30 are at the same height. Correspondingly, a complementary structure is formed between the lower palletizing assembly 111 and the upper palletizing assembly 112, and the lower locking mechanism 1113 and the upper locking mechanism 1123 are at the same height in the complementary area.

[0044] Optionally, the upper lifting frame 1122 is provided with an empty space 1121, and the upper locking mechanism 1123 is distributed on both sides of the empty space 1121. The lower lifting frame 1112 includes a bracket boss 1111 matching the empty space 1121, and the lower locking mechanism 1113 is installed on the bracket boss 1111. The lower lifting frame 1112 is close to or abuts against the upper lifting frame 1122, so that the upper locking mechanism 1123 and the lower locking mechanism 1113 are at the same height, so as to realize the alternating lifting of the oil pressing carrier 30.

[0045] The lower locking mechanism 1113 and the upper locking mechanism 1123 are locked in the same stacking groove 315 position of the oil pressing carrier 30, so as to realize the alternate clamping of the oil pressing carrier 30. The clamping height and position can be precisely controlled, and the moving stroke of the oil pressing carrier 30 can be shortened, which can increase the stacking volume of the oil pressing carrier 30 under the same conditions.

[0046] Preferably, the upper locking mechanism 1123 and the lower locking mechanism 1113 both include telescopically movable stacking shafts, and the support curve formed by the end connection line of multiple stacking shafts is adapted to the stacking groove 315 of the oil pressing carrier 30. The stacking shaft is adapted to the stacking groove 315 to balance the force of the oil pressing carrier 30. The stacking shaft runs through the lower lifting frame 1112 (upper lifting frame 1122), and the sliding matching area of the stacking shaft remains unchanged during the telescopic sliding process, which can provide stable support force and anti-bending and torsion capabilities.

[0047] like Figures 2 to 4 As shown, the bottom bracket 12 is a rigid frame that can receive the oil pressing vehicle 30 input from the outside. The bottom bracket 12 is provided with a central boss 121 and a drainage groove 122 surrounding the central boss 121, and the central boss 121 is configured as a disc-shaped structure. The central boss 121 is a boss structure, and the outer diameter of the central boss 121 is slightly larger than the outer peripheral wall of the oil pressing vehicle 30 to shorten the flow path of the oil.

[0048] The oil pressing vehicle 30 is grasped and placed on the central boss 121 , and the lifting device 13 pushes the bottom bracket 12 to move upward, and the oil of the oil pressing vehicle 30 is discharged into the drainage groove 122 .

[0049] Furthermore, the central boss 121 is provided with a plurality of concave radial grooves, which intersect with the drainage grooves 122, and the central boss 121 is used to carry the oil pressing carrier 30. The radial grooves extend radially from the center of the central boss 121 to the periphery to guide the oil in the bottom area of the oil pressing carrier 30 into the drainage grooves 122, and the oil emptying effect is good.

[0050] Furthermore, the oil pressing equipment also includes an oil guide pipeline 124 and an oil guide frame 123 installed on the bottom bracket 12 . The oil guide frame 123 is detachably connected to the bottom bracket 12 , and the oil guide frame 123 can switch the oil flow path of the guide drainage groove 122 and the oil guide pipeline 124 .

[0051] Among them, the oil guiding rack 123 is installed at the outlet of the drainage groove 122. The oil guiding rack 123 is provided with an inwardly concave guiding groove. The height of the guiding groove is less than or equal to the outlet of the drainage groove 122, so that the drainage groove 122 can guide the oil into the oil guiding pipeline 124 through the guiding groove.

[0052] Among them, the oil guiding pipeline 124 is provided with a lateral long hole 1241. The output end of the oil guiding rack 123 is inserted into the long hole 1241. The length direction of the long hole 1241 is parallel to the sliding direction of the oil guiding rack 123. The oil guiding rack 123 moves up and down with the bottom bracket 12, and the oil guiding rack 123 moves up and down along the long hole 1241, so that the oil can always enter the oil guiding pipeline 124.

[0053] As Figures 3 to 6 shown, the oil pressing carrier 30 includes a disc body 31, a blanking component 33 and an oil pan bottom plate 32. The disc body 31 is provided with a pressing cavity. Among them, the blanking component 33 includes a blanking plate 331 and a guide post mechanism 332 fixedly connected to the blanking plate 331. The blanking plate 331 is adapted to the shape of the pressing cavity and is laid at the bottom of the pressing cavity. The guide post mechanism 332 slides in the blanking hole to drive the blanking plate 331 to slide along the pressing cavity without detaching the blanking plate 331 from the disc body 31.

[0054] The oil pan bottom plate 32 is detachably connected to the bottom of the disc body 31 through fasteners. During the stacking and oil pressing process of multiple oil pressing carriers 30, a part of the upper oil pressing carrier 30 is inserted into the pressing cavity of the lower oil pressing carrier 30, and there is a diameter difference in the inserted and mated part, so as to form an overflow space. The oil pan bottom plate 32 moves towards the blanking plate 331 in the pressing cavity. Both the oil pan bottom plate 32 and the blanking plate 331 are provided with mesh holes, which can filter and output the oil without introducing oil raw materials, improving the purity of the oil.

[0055] Furthermore, the disc body 31 includes a plurality of oil guiding channels 312 and a plurality of diversion grooves 314. The positioning groove 311 is recessed from the top of the disc body 31. The oil guiding channels 312 penetrate from the positioning groove 311 towards the assembly step 319 of the disc body 31 to form a plurality of channel-shaped holes distributed circumferentially around the disc body 31, so as to quickly discharge the oil converged in the positioning groove 311. As a preference, the more the number of the oil guiding channels 312 and the larger the aperture, the faster the oil diversion speed, and the oil can be quickly discharged to avoid the oil flowing out of the outside of the oil pressing carrier 30. Preferably, the plurality of oil guiding channels 312 are evenly distributed around the center line of the oil pressing carrier 30 to form a balanced conduction path in all directions.

[0056] It is worth mentioning that the oil guiding channels 312 can conduct the stacked oil pressing carriers 30 up and down, and the oil overflowing from the self oil pressing carrier 30 can also flow through the oil guiding channels 312 and the diversion grooves 314.

[0057] Furthermore, the diversion groove 314 is concave in the pressing cavity and penetrates to the assembly step 319 on one side; multiple diversion grooves 314 can quickly discharge the oil in the oil pressing cavity from the side. During the pressing process, the oil can directly flow into the lower side of the assembly step 319 through the diversion groove 314 for output, so as to realize multi-channel oil output in combination with the oil guiding channel 312. Moreover, all the oil converges at the positioning groove 311 of the next oil pressing carrier 30, realizing secondary balanced flow and greatly improving the flow efficiency.

[0058] The sieve plate 34 is plugged and connected to the corresponding diversion groove 314, and a plurality of oil passing sieve holes are evenly distributed on the sieve plate 34. The sieve plate 34 filters the oil through the oil passing sieve holes to prevent the slag from entering the diversion groove 314, achieving a filtering effect.

[0059] The step surface of the assembly step 319 is locally protruded to form a positioning rib 318, and the oil guiding channel 312 connects the positioning groove 311 and the positioning rib 318. On the plane perpendicular to the axis of the oil pressing carrier 30, the highest protruding point of the positioning rib 318 is within the projection range of the positioning groove 311. Correspondingly, the positioning rib 318 is a gradually shrinking convex structure, and the oil in the oil guiding channel 312 is guided by the positioning rib 318 and falls into the positioning groove 311 to realize directional flow.

[0060] Preferably, the positioning rib 318 is set as a triangular protrusion, a curved surface protrusion or a hemispherical protrusion. The end size of the positioning rib 318 is small, which can guide the oil to flow towards the outer peripheral wall surface of the small end of the assembly step 319 and change the liquid flow direction.

[0061] Furthermore, the positioning rib 318 is provided with an outer conical surface 317, and the positioning groove 311 is provided with a matching inner conical surface 316. The cone angle of the outer conical surface 317 is the same as that of the inner conical surface 316. The outer conical surface 317 and the inner conical surface 316 are complementary conical surface structures. When the outer conical surface 317 and the inner conical surface 316 are closed, a sealing surface of two adjacent oil pressing carriers 30 is formed, forming a channel space with a closed outer edge and circular flow of internal oil.

[0062] In a preferred embodiment, there is a height difference between the two sides of the positioning groove 311. Among them, the height of the inner groove wall of the positioning groove 311 is less than the height of the outer groove wall of the positioning groove 311 to block the oil from flowing outwards and keep the oil flowing out through the oil guiding channel 312.

[0063] Furthermore, a plurality of notch grooves 313 are provided at intervals on the inner groove wall of the positioning groove 311. The plurality of notch grooves 313 communicate the positioning groove 311 with the pressing cavity, so that a part of the oil squeezed out of the oil material can enter the positioning groove 311 through the notch grooves 313, and then the oil is output directionally through the oil guiding channel 312. At the same time, the notch grooves 313 can further reduce the risk of oil output from the outer groove wall of the positioning groove 311. Optionally, the notch grooves 313 are distributed at intervals around the center line of the oil pressing carrier 30. For example, the number of the notch grooves 313 can be set to more than one.

[0064] In one embodiment, on the circumferential line where the center line of the oil guiding channel 312 is located, the ratio of the sum of the arc lengths of the oil guiding channel 312 to the circumferential line is set to K, where 0.2 ≤ K ≤ 0.6. The oil guiding channel 312 can be set in a circular hole shape or an arc hole shape to penetrate through the upper and lower ends of the oil pressing carrier 30.

[0065] To expand the diversion efficiency and channel area of the oil guiding channel 312, the center lines of the plurality of oil guiding channels 312 are on the same diameter, and adjacent two oil guiding channels 312 are separated by a wall body.

[0066] To improve the flow efficiency of the oil, the blanking plate 331 is provided with an inwardly concave diversion mesh groove, so as to form a network-type flow channel, which not only expands the flow area, but also forms an overhead structure, maintains the supporting effect, and has high bending and torsional strength.
