Description

Technical Field

[0001] This invention relates to the field of crushing or pulverizing, specifically to a camellia seed pulverizing device for camellia oil production. Background Technology

[0002] Camellia oil, a high-quality edible oil, is a vegetable oil extracted from the seeds of the camellia plant. In the production process, camellia seeds undergo drying, shelling, crushing, steaming, roasting, cake making, and pressing before being pressed. Finally, after filtration to remove impurities, pure camellia oil is obtained.

[0003] Camellia oil seeds are approximately 2.5 cm in diameter. Due to their high content of hemicellulose, cellulose, and lignin, they are extremely hard. Before grinding, the seeds need to be initially crushed by pressing them into a flat shape, followed by secondary grinding. When grinding camellia seeds, a grinder is often used to pulverize the shelled seeds into powder to increase the oil yield. The grinder has grinding blades inside its casing, driven by a motor to rotate and grind the seeds. For example, Chinese Patent CN219559859U describes a camellia seed grinding device. However, in this application, the grinding blades rotate in the same direction, resulting in relatively low grinding efficiency for camellia oil and other materials. Summary of the Invention

[0004] The purpose of this invention is to provide a camellia seed crushing device for camellia oil production, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a camellia seed crushing device for camellia oil production, comprising: A support plate, with a support frame fixedly installed at its bottom; The pulverizing chamber is located below the support plate; The upper support plate is fixed to the support plate by the column, and a support ring is installed between the upper support plate and the support plate; The driven shaft is installed inside the support ring. A cam groove is provided on the side of the driven shaft. An outer shaft is fixedly installed at the bottom of the driven shaft and is coaxially arranged with it. An inner shaft is rotatably installed at the axis of the driven shaft and the outer shaft. The two ends of the inner shaft are located outside the driven shaft and the outer shaft. The bottoms of the inner shaft and the outer shaft are inserted into the crushing box. The first blade is fixed to the bottom of the outer shaft; The second blade is fixed at the bottom of the inner shaft; A support column, one end of which is connected to a support ring, and the other end of which is inserted into a cam groove; When the inner shaft rotates, it can rotate the driven shaft, the outer shaft and the inner shaft together. The outer shaft and the inner shaft rotate the first blade and the second blade respectively to cut the material.

[0007] Preferably, the crushing chamber and the support plate are movably connected.

[0008] Preferably, the support ring is rotatably mounted between the upper support plate and the support plate. The inner sidewall of the support ring has an elliptical groove. A guide rail is fixedly mounted on the upper side of the support plate. There are two guide rails, which are symmetrically fixed on the upper side of the support plate. A slider is slidably mounted in each of the two guide rails. A support column is fixedly mounted on the slider. One end of the support column of one slider is inserted into the groove and the other end is inserted into the cam groove. One end of the other slider is inserted into the cam groove and the other end is flush with the side of the slider. When the driven shaft rotates, the two sliders can move synchronously in the guide rails.

[0009] Preferably, the bottom of the crushing box is open, and a base plate is detachably installed at the bottom opening of the crushing box by bolts. The base plate is set as a grid structure.

[0010] Preferably, a collection box is provided at the bottom of the crushing box, and the outside of the collection box is fixedly connected to the support frame; The top of the collection box is open, the lower part of the crushing box extends into the collection box, and the crushing box can slide up and down in the collection box.

[0011] Preferably, the support ring is a cylindrical structure with a closed top and an open bottom, and thrust bearings are installed between the bottom open side of the support ring and the support plate, and between the driven shaft and the support plate.

[0012] Preferably, the support ring is fixedly installed between the upper support plate and the support plate.

[0013] Preferably, the circle of the slide groove coincides with the axis of the support ring, and the span of the slide groove in the axial direction of the support ring is the same as the span of the cam groove in the axial direction of the driven shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention incorporates an inner shaft, an outer shaft, a support ring, a driven shaft, a slider, and a support column. When the inner shaft rotates, the outer shaft and the driven shaft rotate together with it. Under the limiting action of the support ring and the support column, the outer shaft can move up and down inside the crushing chamber. While cutting and crushing the material, it can also move the material up and down, achieving material tumbling, improving the crushing effect, and realizing longitudinal cutting of the material.

[0015] At the same time, the first blade will move closer to or further away from the second blade. When the first blade moves upward, it carries the material upward, increasing the gap between the materials at the bottom of the crushing chamber. When the second blade cuts the material, the materials can collide and tumble better, improving the cutting effect. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-3 As shown, this embodiment provides a camellia seed crushing device for camellia oil production, including a support plate 1. A support frame 10 is fixedly installed at the bottom edge of the support plate 1, supporting the support plate 1 and ensuring that the support plate 1 has sufficient height for installing various components. A crushing box 14 is fixedly installed on the bottom surface of the support plate 1. A base plate 13 is bolted to the bottom of the crushing box 14. The base plate 13 is designed with a grid structure and can be removed from the bottom of the crushing box 14 for replacement with base plates of different grid sizes. A feed inlet 17 is provided on the top side of the crushing box 14. The camellia seeds to be crushed are put into the crushing box 14 through the feed inlet 17 for crushing. During the crushing process, materials with a diameter smaller than the grid of the base plate 13 will fall down through the base plate 13, while materials with a diameter larger than the grid will continue to be crushed in the crushing box 14 due to the obstruction of the base plate 13.

[0020] Four columns 7 are fixedly installed on the upper end of the support plate 1. An upper support plate 5 is fixedly installed on the upper end of the columns 7. A motor 4 is fixedly installed on the upper support plate 5. The motor 4 serves as the drive source for the entire device and provides power for the operation of the entire device.

[0021] A support ring 3 is rotatably installed between the upper support plate 5 and the support plate 1, such as... Figure 1 and Figure 2 As shown, the support ring 3 is a cylindrical cavity structure with a closed top and an open bottom. An inner ring is fixedly installed inside the support ring 3, and an elliptical groove 31 is formed on the inner ring. Figure 1 As shown, the center of the groove 31 coincides with the axis of the support ring 3; a thrust bearing 32 (also known as a thrust bearing, which can be a thrust ball bearing or a thrust roller bearing, and can withstand axial loads, is installed between the bottom opening of the support ring 3 and the top of the support plate 1) is installed inside the support ring 3. The driven shaft 8 is rotatably installed inside the support ring 3. The driven shaft 8 is coaxially arranged with the support ring 3. Thrust bearings are installed between the top of the driven shaft 8 and the support ring 3, and between the bottom of the driven shaft 8 and the support plate 1.

[0022] A cam groove 81 is provided on the side of the driven shaft 8, such as Figures 1-3As shown, the cam groove 81 is composed of two symmetrical arc-shaped grooves and surrounds the outer circular surface of the driven shaft 8. An outer shaft 16, coaxially arranged with the driven shaft 8, is fixedly mounted at the bottom of the driven shaft 8. An inner shaft 15, axially arranged, is mounted at the axial center of the driven shaft 8 and the outer shaft 16, and the inner shaft 15 can rotate at the axial center of the outer shaft 16 and the driven shaft 8; Figure 6 As shown, the top of the inner shaft 15 extends from the upper end of the driven shaft 8. The upper end of the inner shaft 15 is fixedly connected to the upper end face of the support ring 3, and the upper end of the inner shaft 15 is fixedly connected to the output shaft of the motor 4. The motor 4 is used to rotate the inner shaft 15 and the support ring 3. A through hole is provided at the center of the top of the crushing box 14. The outer shaft 16 extends into the interior of the crushing box 14 through the through hole and can rotate in the through hole. The bottom of the inner shaft 15 extends from the bottom of the outer shaft 16, and the lower parts of both the inner shaft 15 and the outer shaft 16 extend into the interior of the crushing box 14. The bottom of the outer shaft 16 is fixedly installed with a first blade 11, and the bottom of the inner shaft 15 is fixedly installed with a second blade 12.

[0023] A guide rail 6 is fixedly mounted on the upper side of the support plate 1. The left and right sides of the guide rail 6 are open cavity structures, such as... Figure 1 and Figure 2 As shown, the guide rail 6 extends upward into the interior of the support ring 3, and the height of the guide rail 6 is the same as the distance between the top of the inner cavity of the support ring 3 and the top surface of the support plate 1. A slider 2 is slidably installed inside the guide rail 6, and the slider 2 can slide up and down inside the guide rail 6. In this embodiment, limit blocks are provided on both sides of the slider 2 that contact the guide rail 6, and vertically distributed limit grooves are provided on the inner sidewall of the guide rail 6. Under the action of the limit blocks and limit grooves, the slider 2 can slide stably in the guide rail 6 and will not fall off from the opening side of the guide rail 6.

[0024] like Figure 1 As shown, a support column 21 is fixedly installed on the slider 2. One end of the support column 21 is inserted into the slide groove 31, and the other end is inserted into the interior of the cam groove 81. In this embodiment, the span of the slide groove 31 in the axial direction of the support ring 3 is the same as the span of the cam groove 81 in the axial direction of the driven shaft 8, and the highest point and the lowest point of the slide groove 31 are respectively set to correspond to the highest point and the lowest point of the cam groove 81.

[0025] When motor 4 is powered, its output shaft drives the inner shaft 15 and support ring 3 to rotate, with the inner shaft 15 and support ring 3 rotating in the same direction. When support ring 3 rotates, it drives support column 21 and slider to move up and down in guide rail 6 under the influence of slide groove 31. Simultaneously, support column 21 exerts a thrust on cam groove 81, causing driven shaft 8 to move in the opposite direction. Figure 2 As shown, taking the clockwise rotation of the inner shaft 15 as an example: when the inner shaft 15 rotates counterclockwise, it moves the support column 21 and the slider 2 downwards (as shown in the image). Figure 2As shown by the middle arrow a), the downward movement of the support column 21 exerts a downward thrust on the bottom sidewall of the cam groove 81, thereby causing the driven shaft 8 to rotate clockwise (as shown by the arrow a). Figure 2 (As shown by arrow b) When the support column 21 and the slider 2 move to the bottom of the cam groove 81 and move upward, the upward movement of the support column 21 generates an upward thrust on the upper side wall of the cam groove 81, causing the driven shaft 8 to continue to rotate.

[0026] Thus, it can be seen that the rotation direction of the driven shaft 8 is opposite to that of the inner shaft 15. Since the outer shaft 16 is fixedly connected to the bottom of the driven shaft 8, the rotation direction of the outer shaft 16 is opposite to that of the inner shaft 15. That is to say, the rotation directions of the first blade 11 on the outer shaft 16 and the second blade 12 on the inner shaft 15 are opposite. When crushing materials such as tea oil seeds, because the rotation directions of the two blades are opposite, there is a greater relative speed between the two blades, resulting in a greater shearing force on the material located between the two blades, and a better crushing effect. The frictional force generated by the first blade 11 on the material along the rotation direction of the first blade 11 when it rotates, and the frictional force generated by the second blade 12 on the material along the rotation direction of the second blade 12 when it rotates, are due to the opposite rotation directions of the first blade 11 and the second blade 12. Figure 11 As shown by the arrow, the material between the two blades will form a vortex, which allows the material to flow and circulate better, improving the material cutting effect.

[0027] Moreover, the inner shaft 15 and the outer shaft 16 are driven by the same motor, saving the drive source and making it more energy-efficient. When crushing materials, the materials will move towards the inner wall of the crushing box 14 under the action of centrifugal force and accumulate inside the crushing box 14. After the accumulated materials reach a sufficient height, they will roll down and fall. Since the inner shaft 15 and the outer shaft 16 are coaxially set (the inner shaft 15 is located inside the outer shaft 16), when the materials roll, they can fall down along the common outer shaft 16, reducing the obstruction to the rolling of the materials.

[0028] Please see Figures 4-8 The difference from Embodiment 1 is that two guide rails 6 are provided, and the crushing box 14 is movably installed directly below the support plate 1. The differences are described in detail below: like Figure 4 As shown, two guide rails 6 are provided, symmetrically fixed to the upper side of the support plate 1 about the axis of the support plate 1. A slider 2 is slidably installed in each guide rail 6, and a support column 21 is fixedly installed on the slider 2. One end of the support column 21 of one slider 2 is inserted into the slide groove 31, and the other end is inserted into the cam groove 81; one end of the support column 21 of the other slider 2 is inserted into the cam groove 81, and the other end is flush with the side of the slider 2. Figure 4 and Figure 5As shown, the support columns of the two sliders 2 are located in the two arc-shaped grooves of the cam groove 81 and are arranged symmetrically. When the driven shaft 8 rotates, the two sliders 2 can move synchronously in the guide rail 6. Of the two support columns 21, only one support column 21 is connected to the driven shaft 8 and the support ring 3 and moves as the driving member, while the other support column 21 is only connected to the driven shaft 8 and acts as the driven member.

[0029] like Figures 4-8 As shown, the crushing box 14 is located directly below the support plate 1 and is not connected to the support plate 1. Two symmetrically arranged sliders 9 are fixedly installed on the upper surface of the crushing box 14, and the positions of the two sliders 9 correspond to the two guide rails 6 respectively. Two through holes are opened on the support plate 1, through which the sliders 9 pass and extend into the interior of the guide rails 6. One end of the slider 9 inside the guide rail 6 is fixedly connected to the slider 2. When the slider 2 slides up and down inside the guide rail 6, the slider 2 can move up and down in the guide rail 6 with the slider 9, and the slider 9 can move up and down with the crushing box 14. Since the lengths of the inner shaft 15 and the outer shaft 16 remain unchanged and do not move up and down with the crushing box 14, when the crushing box 14 moves up and down (the direction of movement of the crushing box 14 is perpendicular to the cutting direction of the two blades), the positions of the first blade 11 and the second blade 12 in the crushing box 14 change at any time, which can realize dynamic crushing of the material inside the crushing box 14. During the up and down movement of the crushing box 14, the material can circulate better inside the crushing box 14. Furthermore, when the crushing box 14 moves up and down and changes direction, the frequent reversal causes the crushing box 14 to vibrate. This vibration causes the material inside the crushing box 14 to fall off the bottom plate 13, which can accelerate the speed at which the material falls through the screening and also prevent the crushed material from clogging the mesh.

[0030] like Figure 7 As shown, when slider 2 moves upward along with slider 9 and crushing box 14 (as shown), Figure 7 As shown by the dashed arrow c), since the heights of the first blade 11 and the second blade 12 remain constant (i.e., the heights of the two blades remain constant), the two blades move downwards relative to the crushing chamber 14. The two blades compress the material at the bottom of the crushing chamber 14, and simultaneously, the rotation of the two blades cuts and crushes the material. Under the centrifugal force of the blades, the material moves towards the side wall of the crushing chamber 14 and accumulates. As the crushing chamber 14 moves upwards, the blades get closer and closer to the bottom of the crushing chamber 14. During this process, the material accumulating on the side wall of the crushing chamber 14 continuously tumbles downwards. Figure 7As shown by the solid arrow d, the closer the blade is to the bottom of the crushing box 14, the closer the material at the bottom will be to the side wall of the crushing box 14 after being cut, and it will accumulate upwards. Since there are no obstructions at the top of the crushing box 14, the material can roll from the side wall of the crushing box 14 to the center of the crushing box 14 onto the blade, which can better achieve the recycling and crushing of the material.

[0031] When the crushing chamber 14 moves downwards, as Figure 8 As shown by the dashed arrow e, the first blade 11 and the second blade 12 move upward relative to the crushing chamber 14. After being cut by the two blades, the material moves towards the side wall of the crushing chamber 14 under the centrifugal force of the blades, and then accumulates and mixes together at the bottom of the crushing chamber 14. Figure 8 As shown by the solid arrow f, after the crushing chamber 14 moves to the bottom, it moves upward. The two crushing blades move downward relative to the crushing chamber 14 to cut the material accumulated at the bottom of the crushing chamber 14 again. This cycle repeats, and the multi-directional dynamic cyclic cutting improves the crushing efficiency of the material.

[0032] During material collection, because the crushing box 14 moves upward, the crushed material falls downward through the mesh of the bottom plate 13, making collection difficult. Furthermore, the material is more prone to splashing when the crushing box 14 moves up and down. To better collect the crushed material, in a further embodiment, a collection box 18 is provided at the bottom of the crushing box 14. The outer wall of the collection box 18 is bolted to the support frame 10. Figure 9 and Figure 10 As shown, the collection box 18 is a cylindrical structure with an open top. The lower part of the crushing box 14 extends into the collection box 18, and the crushing box 14 can slide up and down inside the collection box 18. During the up and down movement of the crushing box 14, the powder falling from the bottom plate 13 will fall directly into the collection box 18. The bottom of the collection box 18 is a conical structure, and a discharge port is opened at the bottom of the collection box 18, through which the material in the collection box 18 can fall. In this embodiment, the collection box 18 does not move with the crushing box 14, which facilitates the discharge of material from the collection box 18 to the outside, and also facilitates the collection of material from the crushing box 14.

[0033] In Example 2, dynamic pulverization of camellia seeds can be achieved by the up-and-down movement of the pulverizing box 14. The application also found that dynamic pulverization of camellia seeds can be achieved by the up-and-down movement of the blades, as specifically set as follows: like Figure 12 and Figure 13As shown, a support frame 10 is fixedly installed at the bottom of the support plate 1. The crushing box 14 is located below the support plate 1. A feed inlet 17 is opened on the top side of the crushing box 14. The tea oil seeds to be crushed are put into the crushing box 14 through the feed inlet 17 for crushing. A bottom plate 13 is bolted to the bottom of the crushing box 14. The bottom plate 13 is designed with a grid structure. The above structure is set up in the same way as in Embodiment 1.

[0034] A column 7 is fixedly installed at the bottom of the upper support plate 5. The column 7 is fixedly installed on the support plate 1. A support ring 3 is fixedly installed between the upper support plate 5 and the support plate 1. The top and bottom of the support ring 3 are fixedly connected to the upper support plate 5 and the support plate 1, respectively.

[0035] A motor 4 is fixedly installed on the top of the upper support plate 5. The motor 4 serves as the drive source for the entire device, providing power for its operation. An inner shaft 15 is fixedly installed on the output shaft of the motor 4. The inner shaft 15 passes through the support ring 3 and extends into the interior of the crushing box 14. A second blade 12 is fixedly installed at one end of the inner shaft 15 located in the crushing box 14.

[0036] A driven shaft 8 is installed inside the support ring 3. An outer shaft 16 coaxially arranged with the driven shaft 8 is fixedly installed at the bottom of the driven shaft 8. The driven shaft 8 and the outer shaft 16 are both coaxially arranged with the inner shaft 15. The bottom of the inner shaft 15 extends out from the bottom of the outer shaft 16, and the lower parts of the inner shaft 15 and the outer shaft 16 extend into the interior of the crushing box 14. A first blade 11 is fixedly installed at the bottom of the outer shaft 16.

[0037] The inner shaft 15, located inside the support ring 3, has an axially oriented sliding groove. A slider matching the sliding groove is fixedly installed on the inner side wall of the driven shaft 8. The driven shaft 8 can slide up and down along the outer side wall of the inner shaft 15, and can also rotate with the inner shaft 15. A support column 21 is fixedly installed in the middle of the inner side wall of the support ring 3. A cam groove 81 is formed on the outer side wall of the driven shaft 8, and the end of the support column away from the support ring 3 is inserted into the cam groove 81.

[0038] When the inner shaft 15 rotates together with the driven shaft 8, the cam groove 81 slides along the outer side of the support column 21, thereby causing the driven shaft 8 to slide up and down on the outer side of the inner shaft 15. That is, the driven shaft 8 can move up and down inside the support ring 3. In this embodiment, the inner height of the support ring 3 is preferably half the height of the crushing box, and the distance that the driven shaft 8 moves up and down is close to half the height of the crushing box 14.

[0039] like Figure 12 As shown, when the support column 21 is located at the top of the cam groove 81, the driven shaft 8 is located at the bottom of the inner cavity of the support ring 3; when the support column 21 is located at the bottom of the cam groove 81, the driven shaft 8 is located at the top of the inner cavity of the support ring 3.

[0040] In this embodiment, when the driven shaft 8 moves up and down, it will cause the outer shaft 16 to move up and down, and the outer shaft 16 will cause the first blade 11 to move up and down, thereby realizing the dynamic crushing of the material inside the crushing box 14.

[0041] like Figure 12 As indicated by the middle arrow, when the driven shaft 8, outer shaft 16, and first blade 11 move upwards, they can cause the material at the bottom of the crushing chamber 14 to tumble upwards. Simultaneously, the first blade 11 cuts and crushes the material, achieving the purpose of crushing while tumbling the material, thus achieving vertical or longitudinal cutting. Meanwhile, the second blade 12 remains constant at the bottom of the crushing chamber 14. During the upward movement of the first blade 11, it provides an upward force to the material, making the material relatively loose. Due to the increased looseness of the material, the relative movement space between the materials increases when the second blade 12 cuts the material, allowing for better collision and tumbling, thus improving the cutting effect of the second blade 12.

[0042] When the driven shaft 8, outer shaft 16, and first blade 11 move downwards, the first blade 11 moves downwards (i.e., the first blade 11 approaches the second blade 12) and exerts a downward force on the material, causing the material to tend to move downwards (or moving downwards with some material), thus compressing the material between the two blades and improving the crushing effect. Simultaneously, the pressure exerted by the first blade 11 on the material causes it to move towards the bottom of the crushing chamber 14, reducing the gap between the materials. When the second blade 12 cuts, it can cut more material, improving the cutting efficiency.

[0043] In this embodiment, when the outer shaft 16 moves up and down inside the crushing box 14, since the outer shaft 16 has a certain volume and height, when the outer shaft 16 moves upward inside the crushing box 14, the internal space of the crushing box 14 increases, which will generate negative pressure, and external gas will enter the interior of the crushing box 14.

[0044] In this embodiment, a sealing cover is provided at the feed inlet 17 to cover and seal the feed inlet 17. When the feed inlet 17 is covered and sealed, when the outer shaft 16 moves upward inside the crushing box 14, the negative pressure generated inside the crushing box 14 causes air to enter the mesh of the bottom plate 13, generating an upward airflow. This airflow exerts an upward force on the material. During the upward movement of the outer shaft 16, under the action of the airflow and the combined force of the upward movement of the first blade 11, the material can be better tumbled and mixed inside the crushing box 14.

[0045] When the outer shaft 16 moves downward inside the crushing chamber 14, it occupies space in the crushing chamber 14. In other words, when the outer shaft 16 moves downward inside the crushing chamber 14, the internal space of the crushing chamber 14 becomes smaller and the internal pressure increases. Since the bottom plate 13 of the crushing chamber 14 has a grid structure, the gas carries the material towards the bottom plate 13 and accumulates on the bottom plate 13, which allows the second blade 12 to cut and crush more material.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
