Description

Technical Field

[0001] The invention relates to the field of crushing or pulverizing, and in particular to a camellia seed pulverizing device for producing camellia oil. Background Art

[0002] Tea oil is a high-quality edible oil extracted from the seeds of the tea plant. In the process of tea oil production, the tea seeds need to go through the processes of drying, shelling, crushing, steaming, frying, cake making, pressing, etc. before oil extraction. Finally, after filtering to remove impurities, pure tea oil can be obtained.

[0003] The diameter of tea oil seeds is about 2.5 cm. Since they contain high levels of hemicellulose, cellulose and lignin, they are extremely hard. Before crushing the tea oil seeds, they need to be initially crushed, that is, pressed into a flat shape, and then crushed for the second time. When crushing the tea oil seeds, a grinder is often used to crush the shelled tea oil seeds into powder to increase the oil yield. A crushing knife is provided inside the shell of the grinder, and the crushing knife is driven by a motor to rotate to crush the tea oil seeds. For example, a Chinese patent with a publication number of CN219559859U discloses a tea oil seed crushing device. However, in this application, the crushing blades rotate in the same direction, and the same direction of rotation is used to crush tea seed oil, and the crushing effect is relatively low.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-3 As shown, this embodiment provides a tea seed crushing device for tea oil production, including a support plate 1, a support frame 10 is fixedly installed at the bottom edge of the support plate 1, and the support frame 10 supports the support plate 1 to ensure that the support plate 1 has sufficient height for installing various parts; a crushing box 14 is fixedly installed on the bottom of the support plate 1, and a bottom plate 13 is installed at the bottom of the crushing box 14 by bolts.

A feed port 17 is provided at the top of the side of the crushing box 14, and the tea oil seeds to be crushed are put into the crushing box 14 from the feed port 17 for crushing. During the crushing process, materials with a diameter smaller than the grid of the bottom plate 13 will fall downward from the bottom plate 13, while materials with a diameter larger than the grid will continue to be crushed in the crushing box 14 under the obstruction of the bottom plate 13.

[0020] Four columns 7 are fixedly mounted on the upper end surface of the support plate 1, an upper support plate 5 is fixedly mounted on the upper end of the column 7, and a motor 4 is fixedly mounted on the upper support plate 5. The motor 4 serves as a driving source for the entire device and provides power for the operation of the entire device.

[0021] A support ring 3 is rotatably mounted between the upper support plate 5 and the support plate 1. 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 slide groove 31 is opened on the inner ring. Figure 1 As shown, the center of the slide 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 and a thrust roller bearing, and the thrust bearing can withstand axial loads, which is a prior art) is installed between the bottom opening of the support ring 3 and the top of the support plate 1, and a driven shaft 8 is rotatably installed inside the support ring 3, and the driven shaft 8 is coaxially arranged with the support ring 3, and 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. Figure 1-Figure 3As shown, the cam groove 81 is composed of two symmetrical arc grooves and is arranged around the outer circumferential surface of the driven shaft 8. The bottom of the driven shaft 8 is fixedly installed with an outer shaft 16 coaxially arranged with the driven shaft 8, and an axially arranged inner shaft 15 is installed at the axis center of the driven shaft 8 and the outer shaft 16. The inner shaft 15 can rotate at the axis center of the outer shaft 16 and the driven shaft 8; Figure 6 As shown, the top of the inner shaft 15 extends out from the upper end of the driven shaft 8, the upper end of the inner shaft 15 is fixedly connected to the upper end surface 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, and the motor 4 is used to rotate the inner shaft 15 and the support ring 3; a through hole is opened at the top center of the crushing box 14, the outer shaft 16 extends from the through hole to the inside of the crushing box 14, and the outer shaft 16 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 the inner shaft 15 and the outer shaft 16 both 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, and 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 side wall of the guide rail 6. Under the action of the limit blocks and the limit grooves, the slider 2 can slide stably in the guide rail 6 and will not fall off from the open side of the guide rail 6.

[0024] like Figure 1 As shown, a support column 21 is fixedly mounted 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 arranged corresponding to the highest point and the lowest point of the cam groove 81.

[0025] When the motor 4 is powered on, the output shaft of the motor 4 will rotate with the inner shaft 15 and the support ring 3, and the inner shaft 15 and the support ring 3 rotate in the same direction. When the support ring 3 rotates, driven by the slide groove 31, it will move the support column 21 and the slider up and down in the guide rail 6, and the support column 21 will generate a thrust on the cam groove 81, so that the driven shaft 8 moves 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, the support column 21 and the slider 2 move downward (as shown in FIG. Figure 2As shown by the arrow a in the middle, the support column 21 moves downward to generate a downward thrust on the bottom side wall of the cam groove 81, thereby causing the driven shaft 8 to rotate in the clockwise direction (as shown in FIG. Figure 2 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 known that the rotation direction of the driven shaft 8 is opposite to the rotation direction 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 first blade 11 on the outer shaft 16 and the second blade 12 on the inner shaft 15 rotate in opposite directions. When crushing materials such as tea oil seeds, since the rotation directions of the two blades are opposite, there is a greater relative speed between the two blades, and there is a greater shear force on the material between the two blades, which has a better crushing effect on the material. When the first blade 11 rotates, it generates a friction force on the material along the rotation direction of the first blade 11. When the second blade 12 rotates, it generates a friction force on the material along the rotation direction of the second blade 12. Since the rotation directions of the first blade 11 and the second blade 12 are opposite, Fig.11 As shown in the direction of the arrow, the material between the two blades will form a vortex, allowing for better flow and turnover circulation between the materials, thereby improving the material cutting effect.

[0027] Moreover, the inner shaft 15 and the outer shaft 16 are driven by the same motor, which saves the driving source and is more energy-efficient. When the material is crushed, the material will move toward the inner wall of the crushing box 14 under the action of centrifugal force and accumulate on the inner side of the crushing box 14. After the accumulated material reaches a sufficient height, it will roll down and fall. Since the inner shaft 15 and the outer shaft 16 are coaxially arranged (the inner shaft 15 is located inside the outer shaft 16), when the material rolls, it can fall downward along the common outer shaft 16, reducing the obstruction to the rolling of the material.

[0028] See also Figure 4-Figure 8 , which is different from the first embodiment in that: two guide rails 6 are provided, and the crushing box 14 is movably installed just below the support plate 1. The differences are described in detail below: like Figure 4 As shown, two guide rails 6 are provided, and the two guide rails 6 are symmetrically fixed on the upper side of the support plate 1 with the axis of the support plate 1 as the symmetry axis. Slide blocks 2 are slidably installed in the two guide rails 6, and support columns 21 are fixedly installed on the slide blocks 2. One end of the support column 21 of one slide block 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 slide block 2 is inserted into the cam groove 81, and the other end is flush with the side of the slide block 2, as shown in FIG. Figure 4 and Figure 5As shown, the support columns of the two sliders 2 are respectively located in the two arc 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. Among 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 an active part, while the other support column 21 is only connected to the driven shaft 8, and acts as a driven part.

[0029] like Figure 4-Figure 8 As shown, the crushing box 14 is located directly below the support plate 1 and has no connection with the support plate 1. Two symmetrically arranged slide bars 9 are fixedly installed on the upper end surface of the crushing box 14. The positions of the two slide bars 9 correspond to the two guide rails 6. Two through holes are opened on the support plate 1. The slide bars 9 pass through the through holes and extend into the inside of the guide rail 6. One end of the slide bar 9 located 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 with the slide bar 9 in the guide rail 6, and the slide bar 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 will not move up and down with the crushing box 14, when the crushing box 14 moves up and down (the movement direction of the crushing box 14 is perpendicular to the cutting direction of the two blades (i.e. the movement of the 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. In the process of the crushing box 14 moving up and down, the material can be better circulated inside the crushing box 14. Moreover, when the crushing box 14 moves up and down and changes direction, the frequent changes make the crushing box 14 vibrate, and the vibration can make the material inside the crushing box 14 fall from the bottom plate 13, which can accelerate the speed of material screening and falling, and at the same time prevent the crushed material from clogging the grid.

[0030] like Figure 7 As shown, when the slider 2 moves upward with the slider 9 and the crushing box 14 (as shown in FIG. Figure 7 As shown by the dashed arrow c in the middle, since the height of the first blade 11 and the second blade 12 remains unchanged, that is, the height of the two blades remains unchanged, the two blades move downward relative to the crushing box 14, and the two blades squeeze the material at the bottom of the crushing box 14. At the same time, the rotation of the two blades cuts and crushes the material. Under the action of the centrifugal force of the blades, the material moves to the side wall of the crushing box 14 and forms an accumulation. As the crushing box 14 moves upward, the blades get closer and closer to the bottom of the crushing box 14. When the blades approach the bottom of the crushing box 14, the material on the side wall of the crushing box 14 keeps accumulating and rolling down, as shown in FIG. 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 will accumulate upwards. There is no obstruction on the upper part of the crushing box 14, and the material can roll from the side wall of the crushing box 14 to the center of the crushing box 14 and onto the blade, which can better achieve the cyclic crushing of the material.

[0031] When the crushing box 14 moves downward, Figure 8 As shown by the dotted arrow e, the first blade 11 and the second blade 12 move upward relative to the crushing box 14. After the materials are cut by the two blades, they move toward the side wall of the crushing box 14 under the centrifugal force of the blades, and then accumulate and mix together at the bottom of the crushing box 14. Figure 8 As shown by the solid arrow f, after the crushing box 14 moves to the bottom, it moves upward, and the two crushing blades move downward relative to the crushing box 14 to cut the materials accumulated at the bottom of the crushing box 14 again, and this cycle is repeated. The multi-directional dynamic cycle cutting is used to improve the crushing efficiency of the materials.

[0032] When collecting materials, since the crushing box 14 moves upward, it is not convenient to collect the crushed materials when they pass through the grid of the bottom plate 13 and fall downward. In addition, when the crushing box 14 moves up and down, the materials are more likely to splash. In order to better collect the crushed materials, in a further embodiment, a collection box 18 is provided at the bottom of the crushing box 14, and the outer wall of the collection box 18 is connected to the support frame 10 by bolts, such as Fig. 9 and Fig.10 As shown, the collecting box 18 is a cylindrical structure with an open top, the lower part of the crushing box 14 extends into the collecting box 18, and the crushing box 14 can slide up and down inside the collecting box 18. During the up and down movement of the crushing box 14, the powder falling from the bottom plate 13 will directly fall into the collecting box 18; the bottom of the collecting box 18 is a conical structure, and a discharge port is opened at the bottom of the collecting box 18, and the material in the collecting box 18 can fall from the discharge port. In this embodiment, the collecting box 18 will not move with the crushing box 14, which is convenient for the collecting box 18 to discharge materials to the outside and also convenient for the collection of materials in the crushing box 14.

[0033] In Example 2, the dynamic crushing of the tea seeds can be achieved by the up and down movement of the crushing box 14. The applicant found that the dynamic crushing of the tea seeds can also be achieved by the up and down movement of the blade. The specific settings are as follows: like Fig.12 and Fig.13As shown, a support frame 10 is fixedly installed at the bottom of the support plate 1, a crushing box 14 is located below the support plate 1, and a feed port 17 is provided at the top of the side of the crushing box 14. Tea oil seeds to be crushed are put into the crushing box 14 from the feed port 17 for crushing. A bottom plate 13 is installed at the bottom of the crushing box 14 by bolts, and the bottom plate 13 is designed as a grid structure. The above structure is arranged in the same manner as in Example 1.

[0034] A column 7 is fixedly installed at the bottom of the upper support plate 5, and 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, and 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] The motor 4 is fixedly mounted on the top of the upper support plate 5. The motor 4 serves as the driving source of the entire device and provides power for the operation of the entire device. The output shaft of the motor 4 is fixedly mounted with an inner shaft 15, which penetrates the support ring 3 and extends into the interior of the crushing box 14. The inner shaft 15 is located at one end of the crushing box 14 and is fixedly mounted with a second blade 12.

[0036] A driven shaft 8 is installed inside the support ring 3, and 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 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. The first blade 11 is fixedly installed at the bottom of the outer shaft 16.

[0037] The inner shaft 15 is provided with an axially arranged slide groove at the inner side wall of the support ring 3, and a slider matching the slide groove is fixedly installed on the inner side wall of the driven shaft 8, so that the driven shaft 8 can slide up and down along the outer side wall of the inner shaft 15, and the driven shaft 8 can also rotate with the inner shaft 15. A support column 21 is fixedly installed at the middle of the inner side wall of the support ring 3, and a cam groove 81 is provided 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 with the driven shaft 8, the cam groove 81 slides along the outer side of the support column 21, thereby sliding the driven shaft 8 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 Fig.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 drive the outer shaft 16 to move up and down, and the outer shaft 16 will drive the first blade 11 to move up and down, so as to realize dynamic crushing of the material inside the crushing box 14.

[0041] like Fig.12 As shown by the middle arrow, when the driven shaft 8, the outer shaft 16 and the first blade 11 move upward, the material at the bottom of the crushing box 14 can be rolled upward, and at the same time, the first blade 11 can cut and crush the material, so as to achieve the purpose of crushing while turning the material, and realize the cutting of the material in the vertical direction or longitudinal direction. The second blade 12 keeps a constant position at the bottom of the crushing box 14. During the upward movement of the first blade 11, it provides an upward force to the material, so that the materials become relatively loose. Due to the increase in the looseness of the materials, when the second blade 12 cuts the materials, the relative movement space between the materials increases, and the materials can collide and roll better, which improves the cutting effect of the second blade 12.

[0042] When the driven shaft 8, the outer shaft 16 and the first blade 11 move downward, the first blade 11 moves downward (i.e., the first blade 11 is close to the second blade 12) and provides a downward force to the material, so that the material has a tendency to move downward (or moves downward with part of the material), so that the material between the two blades is squeezed, and the crushing effect is improved. At the same time, the pressure generated by the first blade 11 on the material will cause the material to move to the bottom of the crushing box 14, and the gap between the materials will become smaller. When the second blade 12 cuts, it can cut more materials, thereby improving the cutting efficiency of the material.

[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, negative pressure is generated, and external air will enter the interior of the crushing box 14.

[0044] In this embodiment, a sealing cover is provided at the feed port 17, which can cover and seal the feed port 17. When the feed port 17 is covered and sealed, when the outer shaft 16 moves upward inside the crushing box 14, due to the negative pressure generated inside the crushing box 14, the grid of the bottom plate 13 will enter the air upward, generating an upward airflow, which will generate an upward force on the material. In the process of the outer shaft 16 moving upward, under the dual force of the airflow and the upward movement of the first blade 11, it can be ensured that the material is better tumbled and mixed inside the crushing box 14.

[0045] When the outer shaft 16 moves downward inside the crushing box 14, the outer shaft 16 will occupy the space of the crushing box 14, that is, when the outer shaft 16 moves downward inside the crushing box 14, the internal space of the crushing box 14 becomes smaller and the internal pressure increases. Since the bottom plate 13 of the crushing box 14 is a grid structure, the gas carries the material toward 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 present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
