Description

Technical Field

[0001] The present application relates to the technical field of oil pressing equipment, and in particular to an oil pressing machine. Background Art

[0002] At present, vegetable oils on the market can be divided into cold-pressed oil and hot-pressed oil. Among them, cold-pressed oil is a finished oil formed by low-temperature pressing (40-60℃) of the raw materials for oil pressing, and the nutrients are most intact, but the oil yield of the cold-pressing method is only half of that of the hot-pressing method. Hot-pressed oil is a finished oil formed by physical pressing after the raw materials for oil pressing are roasted at high temperature (120-130℃). Hot-pressed oil has a pure and fragrant taste and a high oil yield.

[0003] Existing oil presses are mainly divided into screw oil presses and hydraulic oil presses. Among them, the screw oil press uses the principle of physical friction and extrusion to extract oil, so the oil obtained will be black and contain high phospholipids. It often needs to be used with an oil filter to remove impurities in the oil; in addition, due to the large axial dimension of the screw shaft, the lateral dimension of the screw oil press is often large and occupies a large space. The equipment cost of the hydraulic oil press is high, the processing capacity of a single machine is small, and manual loading and unloading is required. The manual workload is large, the degree of automation is low, and the work efficiency is low; in order to improve work efficiency, usually more materials are loaded at a time, which leads to a generally thicker oil cake after pressing, and the raw materials in the center of the oil cake are not fully pressed, and the oil yield is relatively low.

[0004] Therefore, how to design a novel oil press to overcome the above-mentioned shortcomings is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0039] Reference Figure 1-17, an embodiment of the present application provides an oil press, comprising a mounting frame 1, a rotating disk 2, a fixed ring 3, an extrusion block 4 and a discharge block 5; the rotating disk 2 can be rotatably arranged on the mounting frame 1, and the rotating axis of the rotating disk 2 is arranged along the left and right direction; the outer ring surface of the rotating disk 2 is provided with at least one mounting groove 21 at intervals along the circumferential direction, and two extrusion blocks 4 are slidably connected in the mounting groove 21; the inner bottom of the mounting groove 21 is provided with a mounting hole 22, and the discharge block 5 is slidably connected in the mounting hole 22 along the radial direction of the rotating disk 2; the fixed ring 3 is fixed to the mounting frame 1, the fixed ring 3 is coaxially sleeved on the outer periphery of the rotating disk 2, and a seal is formed between the fixed ring 3, the rotating disk 2 and the extrusion block 4; a feed port 31 is radially penetrated on the upper side of the fixed ring 3, and an oil outlet 32 ​​and a slag outlet 33 are radially penetrated on the lower side of the fixed ring 3, and the feed port 31, the oil outlet 32 ​​and the slag outlet 33 are arranged at intervals along the circumferential direction of the fixed ring 3; when the mounting groove 21 rotates with the rotating disk 2 When the material discharging block 5 is aligned with the feed port 31, the material discharging block 5 slides radially inwardly, so that the end surface of the material discharging block 5 that deviates from the mounting hole 22 is flush with the inner bottom surface of the mounting groove 21, and the two material extrusion blocks 4 slide in opposite directions, so that a receiving cavity 100 for communicating with the feed port 31 and collecting materials is formed between the two material extrusion blocks 4, the material discharging block 5 and the inner wall of the mounting groove 21; when the mounting groove 21 continues to rotate to the oil outlet 32 ​​following the rotating disk 2, the two material extrusion blocks 4 in the mounting groove 21 The two mounting grooves 21 and 21 gradually slide toward each other to press the material in the accommodating cavity 100 into oil cakes and grease; when the mounting groove 21 rotates with the rotating disk 2 to align with the oil outlet 32, the grease flows out to the outside of the fixed ring 3 through the oil outlet 32; when the mounting groove 21 rotates with the rotating disk 2 to align with the slag outlet 33, the two extrusion blocks 4 in the mounting groove 21 slide in opposite directions, and the discharge block 5 slides radially outward along the rotating disk 2 to push the oil cake to be discharged to the outside of the fixed ring 3 through the slag outlet 33. It should be noted that the rotatable mounting method between the rotating disk 2 and the mounting frame 1 is a prior art, for example, Figure 2 As shown, a mounting shaft 26 is coaxially arranged on the rotating disk 2, and the mounting shaft 26 is rotatably mounted on the mounting frame 1 through a bearing; a driving motor 400 is also arranged on the mounting frame 1, and the output shaft of the driving motor 400 is connected to the mounting shaft 26 through a transmission mechanism 500; by controlling the driving motor 400 to rotate, the rotating disk 2 can be driven to rotate.

[0040] When the oil press is in use, it is only necessary to drive the rotating disk 2 to rotate on the mounting frame 1. Fig.11 , Fig.12 and Fig.14As shown, when the mounting groove 21 rotates with the rotating disk 2 until it is aligned with the feed port 31, the discharge block 5 slides radially inward, so that the end surface of the discharge block 5 that deviates from the mounting hole 22 is flush with the inner bottom surface of the mounting groove 21, and the two extrusion blocks 4 slide in opposite directions, so that the two extrusion blocks 4, the discharge block 5 and the inner wall of the mounting groove 21 form a receiving chamber 100 for connecting to the feed port 31 and for collecting materials. At this time, the material can be added to the receiving chamber 100 through the feed port 31, thereby achieving loading. When the mounting groove 21 continues to rotate with the rotating disk 2 to the position of the oil outlet 32, the two extrusion blocks 4 in the mounting groove 21 gradually slide toward each other, and the two extrusion blocks 4 exert an extrusion effect on the material in the receiving chamber 100, so as to press the material in the receiving chamber 100 into oil cakes and grease, thereby achieving squeezing. As shown in FIG. Fig.11 and Fig.15 As shown, when the mounting groove 21 rotates with the rotating disk 2 to align with the oil outlet 32, the grease can automatically flow out to the outside of the fixing ring 3 through the oil outlet 32 ​​under the action of gravity, thereby automatically achieving oil discharge; while the oil cake is still clamped by the two extrusion blocks 4, so it will not be discharged through the oil outlet 32. Fig.11 and Fig.16 As shown, when the installation groove 21 rotates with the rotating disk 2 to align with the slag outlet 33, the two extrusion blocks 4 in the installation groove 21 slide in opposite directions, and the discharge block 5 slides radially outward along the rotating disk 2 to push the oil cake to be discharged to the outside of the fixed ring 3 through the slag outlet 33, so that the slag can be discharged automatically. Compared with the traditional oil press, the oil press has a novel structure, small space occupation, convenient use, high degree of automation and high working efficiency; in addition, since the working efficiency of the oil press of this structure is high, the weight of a single loading can be reduced accordingly, thereby reducing the thickness of the oil cake after pressing, so that the raw materials in the center of the oil cake are fully squeezed, and the oil yield can be improved.

[0041] Reference Figure 5 as well as Figure 10-12 In some embodiments of the present application, a cavity 23 is provided at the axis of the rotating disk 2, and a sliding hole 24 for connecting the cavity 23 is provided in the mounting hole 22 along the radial direction of the rotating disk 2; a sliding rod 51 is protruded at the position corresponding to the sliding hole 24 on the discharge block 5, and the sliding rod 51 is connected to the sliding hole 24 by sliding along the radial direction of the rotating disk 2; the oil press also includes a driving assembly 6, which is arranged on the mounting frame 1; when the mounting groove 21 rotates with the rotating disk 2 to align with the feed port 31, the driving assembly 6 is used to drive the sliding rod 51 to slide inward along the radial direction of the rotating disk 2, until the mounting groove 21 rotates to align with the slag outlet 33, the driving assembly 6 is used to drive the sliding rod 51 to slide outward along the radial direction of the rotating disk 2. Among them, the movement accuracy of the discharge block 5 can be improved by the sliding cooperation between the sliding rod 51 and the sliding hole 24; the driving assembly 6 can drive the sliding rod 51 to slide automatically, and the operation is simpler.

[0042] Reference Figure 4 as well as Fig.12 In some embodiments of the present application, a limiting portion 52 is provided on the end of the slide bar 51 that deviates from the discharge block 5; the driving assembly 6 includes a first spring 61, a cam 62 and a wheel shaft 63; the cam 62 is coaxially arranged in the cavity 23, and the cam 62 is fixed to the mounting frame 1 through the wheel shaft 63; the first spring 61 is sleeved on the slide bar 51 and is located between the limiting portion 52 and the inner wall of the cavity 23, so as to force the discharge block 5 to slide radially inward until the end of the slide bar 51 close to the limiting portion 52 contacts the outer annular surface of the cam 62; when the mounting groove 21 rotates with the rotating disk 2 to be aligned with the slag outlet 33, the cam 62 forces the discharge block 5 to slide radially outward through the slide bar 51. During operation, the cam 62 is stationary; when the rotating disk 2 rotates, it will drive the slide bar 51 to rotate synchronously; under the action of the first spring 61, the end of the slide bar 51 close to the limit portion 52 can always be in contact with the outer annular surface of the cam 62; when the slide bar 51 rotates to the slag outlet 33 position, the raised portion on the cam 62 automatically forces the slide bar 51 (i.e., the discharge block 5) to slide radially outward. Through this driving mechanism, there is no need to provide a separate power input, the structure is simpler, and the control is more convenient. It should be noted that the wheel axle 63 can be directly fixed to the mounting frame 1, or it can be fixed to a structure connected to the mounting frame 1 (i.e., indirectly fixed to the mounting frame 1).

[0043] In some embodiments of the present application, Fig.14 As shown, when the mounting groove 21 is rotated to align with the feed port 31, the width of the unloading block 5 in the left-right direction is greater than the width of the accommodating cavity 100 in the left-right direction, which can effectively prevent materials, oil cakes, and grease from entering the mounting hole 22. Fig.16 As shown, when the mounting groove 21 is rotated to be aligned with the slag outlet 33, the two extrusion blocks 4 in the mounting groove 21 slide back to back, and the discharge block 5 slides outward along the radial direction of the rotating disk 2, and the left and right ends of the discharge block 5 are respectively in contact with the two extrusion blocks 4, so that the oil cake can be fully pushed to prevent the oil cake from adhering between the two extrusion blocks 4, thereby allowing the oil cake to be fully discharged to the outside of the slag outlet 33.

[0044] Reference Figure 5-8In some embodiments of the present application, a limiting groove 25 is provided on the inner side wall of the installation groove 21 along the left-right direction, and one end of the limiting groove 25 close to the accommodating cavity 100 is hidden between the extrusion block 4 and the inner side wall of the installation groove 21, so as to prevent materials, grease, and oil cakes from entering the limiting groove 25. A limiting block 41 is provided on the extrusion block 4, and the limiting block 41 is connected to the limiting groove 25 by sliding left and right; the oil press also includes a driving member 7 for driving the extrusion block 4 to slide left and right, and the driving member 7 is arranged on the fixing ring 3 or the mounting frame 1. Among them, the movement accuracy of the extrusion block 4 can be improved through the sliding cooperation between the limiting groove 25 and the limiting block 41; in addition, under the action of the driving member 7, the limiting block 41 (i.e., the extrusion block 4) can be automatically driven to slide left and right.

[0045] Reference Figure 3-4 as well as Figure 8-9 In some embodiments of the present application, the driving member 7 includes a second spring 71, a guide post 72 and a circular guide rail 73; the second spring 71 is arranged between the limit groove 25 and the limit block 41, and the second spring 71 is used to force the extrusion block 4 to slide in the direction away from the accommodating cavity 100; the left and right sides of the fixed ring 3 are coaxially provided with guide rails 73, and a driving surface 731 is arranged in the guide rail 73; a guide post 72 is arranged at a position corresponding to the guide rail 73 on the extrusion block 4, and the guide post 72 is slidably connected to the guide rail 73; when the rotating disk 2 rotates, the driving surface 731 forces the guide post 72 to push the extrusion block 4 to slide in the direction close to the accommodating cavity 100. Figure 14-16 As shown, when the driving rotating disk 2 is rotated, the extrusion block 4 can be driven to rotate. After the extrusion block 4 rotates, the guide column 72 slides along the guide rail 73; at the same time, the elastic force generated by the second spring 71 on the limit block 41 makes the end of the guide column 72 that deviates from the extrusion block 4 always contact with the driving surface 731; that is to say, by adjusting the distance between the two corresponding driving surfaces 731, the two extrusion blocks 4 can be driven to move toward each other; specifically, when the two extrusion blocks 4 move from the position of the feed port 31 to the position of the oil outlet 32, the distance between the two corresponding driving surfaces 731 gradually becomes smaller, thereby forcing the two extrusion blocks 4 to gradually move toward each other to achieve squeezing; when the two extrusion blocks 4 move from the position of the oil outlet 32 ​​to the position of the slag outlet 33, the distance between the two corresponding driving surfaces 731 gradually increases, and under the action of the second spring 71, the two extrusion blocks 4 automatically move back to back. It should be noted that, in order to avoid mutual interference between the discharge block 5 and the extrusion block 4, when the two extrusion blocks 4 move from the oil outlet 32 ​​to the slag outlet 33, the distance between the two corresponding driving surfaces 731 should be increased to the maximum before the slide bar 51 contacts the raised part of the cam 62. Fig. 9 As shown, a receiving hole 27 is provided on the rotating disk 2 at a position corresponding to the limiting groove 25 , and the receiving hole 27 can be used to limit and fix the second spring 71 and also helps to reduce the length of the limiting groove 25 .

[0046] Reference Figure 7 In some embodiments of the present application, one end of the guide post 72 close to the driving surface 731 is a spherical structure, which can effectively reduce the friction resistance between the guide post 72 and the driving surface 731.

[0047] Reference Figure 13-16 In some embodiments of the present application, the end face of the extrusion block 4 radially deviating from the mounting groove 21 coincides with the outer ring surface of the rotating disk 2; a gap is provided between the rotating disk 2 and the fixed ring 3, and two sealing rings 200 for sealing the gap are coaxially provided between the rotating disk 2 and the fixed ring 3, the feed port 31, the oil outlet 32 ​​and the slag outlet 33 are all between the two sealing rings 200, and the outer ring surfaces of the two extrusion blocks 4 in the mounting groove 21 are respectively connected to the sealing rings 200 by sliding left and right; a sealing strip 300 for sealing the gap is provided at the junction between the outer ring surface of the rotating disk 2 and the inner side wall of the mounting groove 21 along the left and right directions, and the left and right ends of the sealing strip 300 respectively form a seal with the two sealing rings 200. The gap can prevent the wear caused by the direct contact and seal between the rotating disk 2 and the fixed ring 3, and the sealing strip 300 and the sealing ring 200 can effectively prevent the material, oil cake and grease from entering the gap.

[0048] Reference Fig.11 In some embodiments of the present application, the inner bottom surface of the mounting groove 21 is a curved surface structure, and the curved surface structure is used to disperse the material in the accommodating chamber 100 along the circumferential direction of the rotating disk 2; under the action of the curved surface structure, when the material falls into the accommodating chamber 100 from the feed port 31, it will automatically disperse in the accommodating chamber 100 along the circumferential direction of the rotating disk 2, thereby avoiding material accumulation. It should be noted that the positions of the extrusion block 4 and the discharge block 5 corresponding to the curved surface structure should also be coordinated curved surface structures.
