Description

Technical Field

[0001] This invention relates to the field of press technology, and more particularly to a horizontal four-column compound mold oil press. Background Technology

[0002] Existing horizontal oil presses involve wrapping oilseeds in cloth, stacking and pressing them together, and then using a pressure mechanism to squeeze the oilseeds out. For example, Chinese literature CN204414631U discloses a new type of horizontal hydraulic oil press, which uses a hydraulic cylinder to push and press multiple stacked oilseed bales to extract oil, thereby outputting the oil.

[0003] However, existing horizontal oil pressing equipment requires the oilseeds to be wrapped in cloth and pre-pressed into cakes before being pressed one by one. Not only does the oilseeds need to be wrapped in cloth, making the operation complicated and cumbersome, but the large space between multiple cakes also leads to high oil concentration, resulting in more residual oil after pressing and a reduced oil yield. Therefore, this technical problem needs to be improved. Summary of the Invention

[0004] To overcome the problems existing in related technologies, this invention provides a horizontal four-column composite mold oil press to solve the technical problem of low oil yield due to the need for a cloth wrapping process for oilseeds.

The pressing assembly is provided with a pressing chamber, and the feeding assembly can movably open and close the pressing chamber and the output assembly. Each of the pressing components includes at least one pressing sleeve that slides on the frame and a pressing die column that is matched and inserted into the corresponding pressing sleeve. A pressing space is formed between the pressing die column and the pressing sleeve. The pressing die column is provided with multiple oil pressing channels along the axial direction and at least one oil outlet channel along the radial direction. The oil outlet channel is connected to at least one oil pressing channel. After the oil is filled, the feeding assembly blocks the pressing chamber and the feeding device. The pressing mold moves under the push of the main pressure assembly and presses the oil in the pressing chamber. The oil pressed out flows out along the oil pressing channel and the oil outlet channel.

[0006] In one embodiment, the centerlines of the plurality of oil pressing channels are on the same plane, and an oil outlet channel connects the plurality of oil pressing channels.

[0007] In one embodiment, when there are two or more pressing components, the oil pressing channel connects two adjacent pressing chambers.

[0008] In one embodiment, the horizontal pressing device further includes an air blowing assembly installed on the pressing die column.

[0012] In one embodiment, the feeding device includes at least one material bin for containing oil, a sealing assembly connected to the corresponding material bin, a high-pressure air source assembly, and an output assembly. The sealing assembly is used to movably open and close the material bin opening. After the sealing assembly closes the material bin opening, the high-pressure air source assembly pneumatically outputs the oil in the material bin to the pressing chamber along the output assembly.

[0013] In one embodiment, the output component is telescopically movably connected to the feed component.

[0014] In one embodiment, the pressing assembly is provided in two or more sets, and adjacent sets of the pressing assembly are connected by a tie rod assembly.

[0015] The technical solutions provided by the embodiments of the present invention can include the following beneficial effects: The feeding device directly feeds the oilseeds into the pressing chamber, achieving cloth-free feeding and improving the convenience of oilseed feeding. The pressing die column is inserted into the pressing sleeve to construct a one-chamber-one-column extrusion pressing structure.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] like Figures 1 to 4As shown, this invention provides a horizontal four-column composite mold oil press, which includes a feeding device 200 and a horizontal pressing device 100. The feeding device 200 is used to output oilseeds. The feeding device 200 can stir the oilseeds and convey them to the horizontal pressing device 100 through pneumatic, screw shaft conveying, telescopic mechanism power conveying, or other means.

[0031] The horizontal pressing device 100 includes a frame 10, a fixed mold base 20 fixed to the frame 10, a main pressure assembly 30, a pressing assembly 40 sliding on the frame 10, and a feeding assembly 50 installed on the pressing assembly 40. The pressing assembly 40 is provided with a pressing chamber 43, and the feeding assembly 50 can movably open and close the pressing chamber 43 and the output assembly 90. The frame 10 includes a base frame 11 and a support frame 12 fixed to the base frame 11. The fixed mold base 20 and the support frame 12 are arranged opposite to each other and connected by four guide pillars 13. The main pressure assembly 30 is a main hydraulic cylinder, fixed to the support frame 12, and its output shaft is connected to the pressing mold column 42 of the pressing assembly 40, which is the first mold column.

[0032] Each pressing assembly 40 includes at least one pressing sleeve 41 that slides on the frame 10 and a pressing die 42 that is matched and inserted into the corresponding pressing sleeve 41, forming a pressing space between the pressing die 42 and the pressing sleeve 41. The pressing sleeve 41 is provided with a through-hole-shaped pressing hole 411, and the pressing die 42 is inserted into the pressing hole 411 and moves telescopically along the center line of the pressing hole 411. When both ends of the pressing sleeve 41 are molded and engaged with the adjacent pressing die 42; or when one end of the pressing sleeve 41 is molded and engaged with the fixed mold base 20 and the other end is molded and engaged with the pressing die 42, the closed space of the pressing sleeve 41 forms a pressing chamber 43.

[0033] The pressing die column 42 is provided with multiple oil pressing channels 421 along the axial direction and at least one oil outlet channel 422 arranged radially. The oil outlet channel 422 is connected to at least one oil pressing channel 421. The multiple oil pressing channels 421 are arranged along the axial direction of the pressing die column 42 to guide the oil from different diameters of the pressing chamber 43 out of the pressing chamber 43, thereby realizing oil output. The oil flows directly out from both ends of the pressing chamber 43, and both ends of the pressing chamber 43 are rigidly pressed by the pressing die column 42, resulting in a high concentration of oil and greatly reducing the residual amount of oil in the residue.

[0034] The feeding assembly 50 blocks the pressing chamber 43 and the feeding device 200 after the oil is filled, thus keeping the pressing chamber 43 in a closed state. The pressing die column 42 moves under the push of the main pressure assembly 30 and presses the oil in the pressing chamber 43. The oil pressed out flows out along the oil pressing channel 421 and the oil outlet channel 422.

[0035] like Figures 3 to 6As shown, the feeding device 200 directly feeds the oilseeds into the pressing chamber 43, enabling feeding without the need for a cloth covering and improving the convenience of oilseed feeding. The pressing die column 42 is inserted into the pressing sleeve 41 to construct a single-chamber, single-column extrusion pressing structure. The oil formed by pressing the oilseeds can be output along the axial direction of the pressing die column 42, including the pressing channel 421 and the oil outlet channel 422. This results in less residual liquid in the residue after pressing and a high oil yield. Each pressing chamber 43 is fed independently, and adjacent pressing chambers 43 can share the pressing channel 421 and the oil outlet channel 422 of the pressing die column 42, resulting in good oil flow and high oil extraction efficiency.

[0036] In a preferred embodiment, the centerlines of multiple oil pressing channels 421 are on the same plane, and an oil outlet channel 422 connects multiple oil pressing channels 421. When there are two or more pressing components 40, the oil pressing channels 421 connect two adjacent pressing chambers 43. That is, the oil pressing channels 421 provided in the pressing die column 42 of the middle pressing component 40 extend through both ends to connect two adjacent pressing chambers 43. The blind-hole oil pressing channels 421 provided in the pressing die column 42 of the end pressing component 40 can connect the connected pressing chambers 43. The oil outlet channel 422 connects multiple oil pressing channels 421, which can realize the centralized output of oil and facilitate the collection and summarization of oil.

[0037] In one embodiment, the horizontal pressing device 100 further includes an air blowing assembly 60 mounted on the pressing die column 42. The air blowing assembly 60 includes a telescopic member 61 fixed to the pressing die column 42, a slider 62 fixed to the output shaft of the telescopic member 61, and an air intake assembly 63 connected to the pressing die column 42. The slider 62 slides along the oil outlet channel 422 and blocks at least one oil pressing channel 421. The air intake assembly 63 communicates with at least one oil pressing channel 421, supplying air to the communicating oil pressing channel 421 and flushing the pressing chamber 43. The shaft diameter of the slider 62 is larger than the shaft diameter of the telescopic shaft, and a sliding seal is formed between the outer peripheral wall of the slider 62 and the oil outlet channel 422. An air intake space is formed between the slider 62, the telescopic member 61, and the output shaft, and the air intake assembly 63 communicates with the air intake space.

[0038] The slider 62 slides along the oil outlet channel 422, thereby connecting one or more oil pressing channels 421 to the air intake space, while other oil pressing channels 421 are separated from the air intake channel. When the air intake assembly 63 delivers cleaning gas to the oil pressing channels 421 through the air intake channel, excess oil in the pressing chamber 43 is discharged through the other oil pressing channels 421 into the oil outlet channel 422, thus forming a gas flushing structure to prevent oil stains from forming in the pressing chamber 43. Preferably, there are four, six, eight, or ten oil pressing channels 421, wherein the slider 62 slides to the middle of the pressing die column 42, so that half of the oil pressing channels 421 are connected to the air intake space, and the other oil pressing channels 421 are connected to the outside through the oil outlet channel 422. Furthermore, the air blowing assembly 60 is installed on the pressing die column 42 and moves with the pressing die column 42.

[0039] In one embodiment, the pressing die column 42 includes a plate portion 425 and a column portion 426 protruding from the plate portion 425. The column portion 426 is a columnar structure adapted to the pressing hole 411. The plate portion 425 is located at one end of the column portion 426 to form a flange structure. Oil pressing channels 421 are spaced apart along a direction parallel to the centerline of the column portion 426. The oil pressing channels 421 penetrate the pressing die column 42 located in the intermediate pressing assembly 40; in the pressing die column 42 located in the end pressing assembly 40, the oil pressing channels 421 extend along the column portion 426 to the plate portion 425. An oil outlet channel 422 penetrates the plate portion 425 and intersects and communicates with the oil pressing channels 421. An air blowing assembly 60 is installed in the plate portion 425, and its output shaft is inserted into the oil outlet channel 422. Preferably, one or more oil leakage holes are provided at the lowest point of the pressing chamber 43 to allow oil to flow out.

[0040] Furthermore, the end of the column section 426 is provided with multiple spaced-apart guide grooves 423 and at least one connecting groove 424 intersecting with the guide grooves 423, and the oil pressing channel 421 is connected to the guide grooves 423 or the connecting grooves 424. The multiple guide grooves 423 can be configured as concentric annular grooves, grid-like grooves, or other intersecting channels, and the connecting grooves 424 intersect the multiple guide grooves 423 to ensure that all oil flow paths are unobstructed, thereby facilitating the output of oil produced by pressing oilseeds by the column section 426. Preferably, the guide grooves 423 are configured as three, four, five, six, seven, or eight concentric circles, and the connecting grooves 424 are one or more straight grooves that intersect with the guide grooves 423, thereby forming an interlaced guiding space, ensuring smooth oil flow.

[0041] Furthermore, the horizontal pressing device 100 covers the filter screen assembly 44 at the end of the column portion 426. The filter screen assembly 44 has a multi-filter hole structure 4411, capable of filtering oil and residue, thereby allowing the oil to flow out of the pressing chamber 43 while the residue remains inside the pressing chamber 43. Optionally, the filter screen assembly 44 includes a filter plate 441, which is a plate-like structure with a plurality of spaced-apart filter holes 4411. Preferably, the filter holes 4411 are arranged in a ring around the center of the filter plate 441. Furthermore, the filter screen assembly 44 includes a filter pad 442, which is provided with a plurality of elongated filter holes 4421. Adjacent elongated filter holes 4421 are parallel to each other, and the length of the elongated filter holes 4421 gradually increases from the center to the outer periphery to form a radial region. Optionally, the filter pad 442 is circular, and each filter pad 442 is provided with four to six radial regions.

[0042] Preferably, the filter pad 442 covers the flow guide groove 423, and the filter sheet 441 is attached to the filter pad 442 to form a multi-stage filtration system with good filtration effect. The elongated filter holes 4421 are inclined and can connect multiple filter holes 4411 to change the oil flow direction, resulting in good filtration effect. The elongated filter holes 4421 have a large liquid flow channel size, resulting in good oil flow.

[0043] like Figures 1 to 4 As shown, in one embodiment, the horizontal pressing device 100 further includes a conveyor belt 80 installed on the frame 10, located below the pressing assembly 40. The conveyor belt 80 is installed on the base frame 11. After the pressing assembly 40 opens the mold, the pressed residue falls into the conveyor belt 80, and the conveyor belt 80 outputs the residue, realizing automatic residue discharge.

[0044] Preferably, an oil outlet frame 70 is installed on the frame 10, the oil outlet frame 70 is fixed to the pressing die column 42, and the oil outlet channel 422 is located above the oil outlet frame 70. Optionally, the oil outlet frame 70 has a U-shaped frame structure.

[0045] The feeding device 200 is used to convey oilseeds to the horizontal pressing device 100 to achieve automatic feeding. In one embodiment, the feeding device 200 pneumatically conveys the oilseeds into the pressing chamber 43 of the horizontal pressing device 100. During the feeding process, the feeding assembly 50 opens the feeding channel to allow the oilseeds to enter the pressing chamber 43. The feeding channel is connected to the pressing chamber 43.

[0046] Optionally, the feeding assembly 50 is installed on the pressing sleeve 41. When multiple pressing sleeves 41 are in the closed state, the feeding assembly 50 and the feeding device 200 are connected, so that the oil can enter the pressing chamber 43 along the feeding assembly 50. The feeding assembly 50 includes a feeding frame 52, a feeding piston 53 sliding on the feeding frame 52, and a feeding cylinder 51 connected to the feeding piston 53. The feeding cylinder 51 drives the feeding piston 53 to extend and retract. A feeding port 521 is provided laterally on the feeding frame 52, and the feeding port 521 intersects and communicates with the feeding channel. The feeding piston 53 slides along the feeding channel to control the opening and closing of the feeding port 521 and the feeding channel.

[0047] like Figure 1 , Figure 7 and Figure 8 As shown, in one embodiment, the feeding device 200 includes at least one material bin 202 for containing oil, a sealing assembly 201 connected to the corresponding material bin 202, a high-pressure air source assembly 203, and an output assembly 90. The sealing assembly 201 is used to flexibly open and close the bin opening 2021 of the material bin 202. The material bin 202 can hold a suitable amount of oil; for example, the material bin 202 can hold more than the amount of oil required for a single pressing chamber 43 to press at one time. In the initial state, the sealing assembly 201 controls the bin opening 2021 to open, so that the oil can be automatically loaded into the material bin 202. When enough material has been added, the sealing assembly 201 controls the bin opening 2021 to close, so that the material bin 202 is in a closed state. When the high-pressure gas source component 203 is activated, it fills the material hopper 202 with high-pressure gas. Under the action of gas pressure, the oil enters the pressing chamber 43 along the output component 90, the inlet 521 and the feed channel. Excess gas can be discharged along the oil outlet channel 422, so that the oil can automatically fill the pressing chamber 43 without the need for a cloth, and the filling effect is good.

[0048] Optionally, the sealing assembly 201 includes a telescopic sealing cylinder 2012 and a guide frame 2011 connected to the output end of the sealing cylinder 2012. The guide frame 2011 is located inside the material bin 202. Preferably, the guide frame 2011 has a conical surface on the side facing the bin opening 2021 to guide the oil to disperse into the bin and seal the bin opening 2021 under the action of the high-pressure air source assembly 203.

[0049] Preferably, the feeding device 200 is provided with a material rack 204, the material rack 204 is provided with at least one material funnel 2041, and each material funnel 2041 has a material hopper opening 2021 at the bottom. The material hopper 202 is located inside the material rack 204 to facilitate the entry of oil.

[0050] In one embodiment, the output component 90 is telescopically connected to the feeding component 50, allowing the output component 90 and the feeding component 50 to be movably connected. The output component 90 is fixedly mounted on the frame 10 to form a fixed position. The feeding component 50 moves with the pressing sleeve 41 and is offset relative to the output component 90 depending on the pressing process. The output component 90 includes an output seat 91 fixed to the frame 10, an injection head 92 sliding on the output seat 91, and an injection cylinder 93 connected to the injection head 92. The injection cylinder 93 drives the injection head 92 to telescopically move. The material bin 202 is connected to the output seat 91 via a pipe, and the output seat 91 has an injection channel communicating with the injection head 92. When the injection head 92 is inserted into the feeding component 50, the high-pressure air source component 203 is activated and pneumatically drives the oil along the pipe, injection channel, and injection head 92 into the feeding component 50, avoiding oil contamination and achieving automatic feeding with good feeding effect.

[0051] In one embodiment, the pressing assembly 40 can be provided in multiple groups, such as two, three, five, eight, ten, twelve, etc. When the pressing assembly 40 is provided in two or more groups, adjacent groups of pressing assemblies 40 are connected by a tie rod assembly to achieve linkage control and realize step-by-step closing and pressing.
