Description

Technical Field

[0001] This utility model relates to the technical field of camellia seed oil extraction equipment, specifically a camellia seed oil extraction and filtration mechanism. Background Technology

[0002] Camellia seeds are mainly composed of water, crude fat, starch, crude protein, tea seed polysaccharides, polyphenols, flavonoids, saponins, crude fiber, and a small amount of tannins. Among these, tea polyphenols, camelliaside, and squalene are characteristic bioactive substances with effects such as lowering cholesterol, anti-aging, and tumor prevention. The processing of camellia seeds includes cold-pressing oil extraction.

[0003] Chinese patent CN221626158U discloses a camellia seed cold-rolled oil extraction device. By setting a lifting mechanism, it can control the cleaning mechanism to clean or maintain the filter, thus maintaining oil extraction efficiency and improving reliability. The device includes an extraction cylinder, a cold-rolled oil processing mechanism, and a filter screen. The rear input end of the extraction cylinder is connected to the front output end of the cold-rolled oil processing mechanism. The lower interior of the extraction cylinder is connected to the outer side of the filter screen. It also includes a reciprocating motor, a threaded rod, a threaded tube, a connecting frame, constraint strips, constraint sleeves, a rotating frame, and brush bristles. The top left and right sides of the connecting frame are respectively connected to the bottom ends of a set of constraint strips. The top left and right interior sides of the extraction cylinder are respectively connected to the outer sides of a set of constraint sleeves. The inner side of the constraint sleeves is slidably connected to the outer side of the constraint strips. The bottom interior of the connecting frame is connected to the top of the rotary motor. The output end of the rotary motor is connected to the middle of the top of the rotating frame. The bottom end of the rotating frame is connected to the top of the brush bristles.

[0004] However, the bristles in this invention will wear down, become stained, and breed bacteria after long-term use, thus requiring regular replacement. This invention connects the bristles to the bottom of the rotating frame, but does not describe whether the bristles can be replaced or how to replace them. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a camellia seed oil extraction and filtration mechanism, which aims to achieve the technical effect of quick and convenient replacement of the brush plate.

[0006] A camellia seed oil extraction and filtration mechanism includes an extraction cylinder, a cold-rolled oil processing mechanism, and a filter screen, and also includes a reciprocating motor, a threaded rod, a threaded tube, a connecting frame, a constraint strip, a constraint sleeve, a rotary motor, a rotating frame, and a brush plate;

[0007] The extraction cylinder has a window corresponding to the rotating frame and the brush plate, and the window is equipped with a switch door.

[0008] The brush plate includes a mounting plate and several brush bristles fixed to the bottom of the mounting plate. Two connecting plates symmetrically arranged on the left and right are fixed to the top of the mounting plate. Insertion holes are opened on the opposite side of the two connecting plates.

[0009] The rotating frame has an internal cavity. At the bottom of the rotating frame, there are two connecting slots for connecting plates to be inserted in a mating connection manner. Both connecting slots are connected to the cavity by through holes. Inside the cavity, there are two symmetrically arranged spring pin structures. The two spring pin structures correspond to the two connecting plates respectively. Each spring pin structure includes a sleeve and a pin rod. The sleeve is fixed in the cavity. One end of the pin rod passes through the through hole in a sliding connection manner and is inserted into the insertion hole in a mating connection manner. The other end of the pin rod passes through the sleeve in a sliding connection manner and is fixedly connected to the inner bottom wall of the sleeve by a spring body.

[0010] The rotating frame is equipped with two driving structures, each corresponding to one of the two pin rods. The driving structures are used to drive the pin rods to move into the sleeve, thereby pulling the pin rods out of the insertion hole and compressing the spring body.

[0011] By employing the above technical solution, when the bristles in the brush plate need to be replaced due to wear, stains, and bacterial growth after prolonged use, the switch door is opened, and then the reciprocating motor drives the rotating frame and brush plate to the position corresponding to the window. Next, the drive structure moves the pin rod into the sleeve, and the end of the pin rod that was originally inserted into the socket is pulled out. Simultaneously, the spring body is compressed, creating a rebound force towards the outside of the sleeve. When the pin rod is completely pulled out of the socket, the connecting plate is no longer fixed in the connecting groove. Pulling the connecting plate out of the connecting groove allows the brush plate to be removed from the bottom of the rotating frame. Similarly, when a new brush plate needs to be installed at the bottom of the rotating frame, the drive structure first retracts the pin rod into the cavity and through hole. Then, the connecting plate is inserted into the connecting groove; when the connecting plate is fully inserted into the connecting groove, the socket and through hole align. Next, the drive structure is released, and under the rebound force of the spring body, the pin rod is reset. The end of the pin rod that is away from the sleeve passes through the through hole and is inserted into the insertion hole, thereby fixing the connecting plate in the connecting groove. The brush plate can then be stably installed at the bottom of the rotating frame.

[0012] This invention allows for the replacement of the brush plate, and the process of disassembling and assembling the brush plate is simple and convenient.

[0013] A further feature of this invention is that a fixing plate is fixed to the cavity wall, and the sleeve is fixed to the fixing plate.

[0014] By adopting the above technical solution, the setting of the fixing plate improves the stability of the sleeve in the cavity.

[0015] Further features of this invention: The driving structure includes an active block and a passive block. The passive block is fixedly sleeved on the outside of the pin rod and slides left and right along the cavity wall. It has a first inclined surface. The active block has a through groove extending laterally in the front and back, and a second inclined surface matching the first inclined surface. The active block slides back and forth along the cavity wall and is slidably sleeved on the outside of the pin rod through the through groove. A connecting rod is fixedly connected between the two active blocks. A pressing block is fixed at the middle position of the connecting rod. The other end of the pressing block passes through the rotating frame in a sliding connection manner.

[0016] By adopting the above technical solution, when it is necessary to move the pin rod into the sleeve via the drive structure, the operator presses the pressing block with their finger. The pressing block moves the connecting rod, which in turn drives both drive structures, thereby simultaneously moving both pin rods. The principle of the drive structure driving the pin rod is as follows: the connecting rod moves the driving block, the second inclined surface presses against the first inclined surface, and the pressure on the first inclined surface can be decomposed into a force acting towards the sleeve. Under the action of this force, the driven block moves towards the sleeve. The driven block then moves the pin rod into the sleeve.

[0017] A further feature of this invention is that at least two compression springs are fixedly connected between the connecting rod and the cavity wall.

[0018] By adopting the above technical solution, when the pressing block moves the connecting rod, the compression spring is compressed to generate a rebound force. After the pressing block is released, the rebound force of the compression spring, together with the rebound force of the spring body, ensures that the driving block, driven block, pin rod, connecting rod, and pressing block can all move and reset stably.

[0019] Further features of this invention: The driving structure includes a groove, a slider, and a slide plate. The groove is located on the front outer side wall of the rotating frame and communicates with the cavity, extending laterally to the left and right. The slider slides left and right along the slider. One end of the slider passes into the cavity and is fixedly connected to the pin rod. The other end of the slider passes out of the rotating frame and is fixedly connected to the slide plate. A card plate is fixed on the slide plate.

[0020] By adopting the above technical solution, when it is necessary to move the pin rod into the sleeve via the drive structure, the operator presses two locking plates with two fingers respectively, causing the two locking plates to move towards each other. This simultaneously drives the two drive structures, thereby simultaneously driving the two pin rods. The principle of the drive structure driving the pin rod is as follows: the locking plates drive the sliding plate, the sliding plate drives the slider to move along the slide groove, and the slider drives the pin rod to move.

[0021] Further features of this invention: The extraction cylinder includes an upper part, a lower part, a base, and a lifting device. An upper splicing ring is fixed to the bottom end of the upper part, and a first insertion ring is fixed to the bottom end of the upper splicing ring. A lower splicing ring corresponding to the upper splicing ring is fixed to the top end of the lower part. A first insertion groove is provided at the top end of the lower splicing ring for the first insertion ring to be inserted in a mating connection manner. The filter screen is detachably connected to the interior of the lower splicing ring by bolts. The base is located below the lower part, and support plates are fixed to the left and right sides of the top end of the base. The top ends of the support plates are fixedly connected to the upper splicing ring. The lifting device is installed on the base to drive the lower part to move up and down.

[0022] By adopting the above technical solution, the extraction cylinder can be split into upper and lower parts by moving the lower part downwards using a lifting device, thus facilitating the cleaning of the inner wall of the extraction cylinder. Furthermore, after the upper and lower parts are separated, the filter screen can be removed from the lower splicing ring for easy cleaning. The lower part is then moved upwards by the lifting device until the first insertion ring is fully inserted into the first insertion slot, at which point the upper and lower parts can be spliced ​​together to form a complete extraction cylinder.

[0023] A further feature of this invention is that the bottom end of the upper splicing ring is provided with a second insertion groove, and the top end of the lower splicing ring is fixed with a second insertion ring for inserting into the second insertion groove in a mating connection manner.

[0024] By adopting the above technical solution, when the upper splicing ring and the lower splicing ring are spliced, the second insertion ring is inserted into the second insertion groove, thereby improving the sealing performance when the upper splicing ring and the lower splicing ring are spliced.

[0025] A further feature of this invention is that an annular rubber pad is fixed on the walls of both the first and second insertion slots.

[0026] By adopting the above technical solution, the setting of the annular rubber gasket further improves the sealing performance when the upper and lower splicing rings are spliced.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1:

[0039] A camellia seed oil extraction and filtration mechanism, such as Figures 1-5 As shown, it includes an extraction cylinder, a cold-rolled oil processing mechanism, and a filter screen 44. It also includes a reciprocating motor 1, a threaded rod 2, a threaded tube 3, a connecting frame 4, a constraint bar 5, a constraint sleeve 7, a rotary motor 6, a rotating frame 45, and a brush plate.

[0040] This embodiment is a technical improvement to address the problem of the brush bristles 20 being difficult to replace in the Chinese patent for a camellia seed cold-rolled oil extraction device with authorization announcement number CN221626158U. Therefore, this embodiment does not provide a specific description of the reciprocating motor 1, threaded rod 2, threaded tube 3, connecting frame 4, constraint bar 5, rotary motor 6, and constraint sleeve 7. The reciprocating motor 1, threaded rod 2, threaded tube 3, connecting frame 4, rotary motor 6, constraint bar 5, and constraint sleeve 7 can all be referred to the relevant descriptions in the Chinese patent for a camellia seed cold-rolled oil extraction device with authorization announcement number CN221626158U.

[0041] The extraction cylinder comprises an upper part 8 and a lower part 9. The rear input end of the upper part 8 is connected to the front output end of the cold-rolled oil processing mechanism (this structure can be referred to in the description of "the rear input end of the extraction cylinder is connected to the front output end of the cold-rolled oil processing mechanism" in Chinese Patent No. CN221626158U, a camellia seed cold-rolled oil extraction device). A window corresponding to the rotating frame 45 and the brush plate is provided on one side of the upper part 8, and a hinged door 10 for closing the window is connected to the window. An upper splicing ring 11 is integrally formed at the bottom end of the upper part 8. Two support plates 12 and a first insertion ring 13 located between the two support plates 12 are integrally formed at the bottom end of the upper splicing ring 11. A base 14 is fixedly connected between the bottom ends of the two support plates 12 by bolts (i.e., several base plates are integrally formed at the bottom end of the support plates 12 and attached to the top of the base 14, and bolts are inserted between the base plates and the base 14).

[0042] The lower part 9 is located between the base 14 and the upper part 8, and between the two support plates 12. A discharge pipe 15 is provided at the center of the bottom end of the lower part 9, and a valve is installed on the discharge pipe 15. The top end of the lower part 9 is integrally formed with a lower splicing ring 16 corresponding to the upper splicing ring 11. The top end of the lower splicing ring 16 has a first insertion groove 17 for the first insertion ring 13 to be inserted in a mating connection manner. The filter screen 44 is detachably connected to the inside of the lower splicing ring 16 by bolts (that is, a first mounting block is integrally formed on the inner side wall of the lower splicing ring 16, the filter screen 44 includes an outer frame and an inner screen, and a second mounting block corresponding to the first mounting block is integrally formed on the outer side wall of the outer frame, and bolts pass through the first mounting block and the second mounting block). The lifting device 18 is installed on the base 14 to drive the lower part 9 to move up and down. In this embodiment, the lifting device 18 can be an X-shaped lifting platform. Vertical plates are bolted to both the left and right sides of the top of the X-shaped lifting platform. These two vertical plates are located on the left and right sides of the discharge pipe 15, respectively, and their tops are welded to the outer bottom wall of the lower part 9. The vertical plates ensure sufficient space between the discharge pipe 15 and the top of the X-shaped lifting platform for placing the collection bucket. The X-shaped lifting platform is a mature and widely used device, and will not be described in detail in this embodiment.

[0043] The brush plate includes a mounting plate 19 and several bristles 20 fixed to the bottom of the mounting plate 19 (the fixing method between the bristles 20 and the mounting plate 19 can be referred to as that of a daily necessities brush). The top of the mounting plate 19 has two symmetrically arranged connecting plates 21 integrally formed. Each of the two connecting plates 21 has an insertion hole 22 on its opposite side.

[0044] The rotating frame 45 has an internal cavity 23. Two connecting slots 24 are provided at the bottom of the rotating frame 45 for the connecting plates 21 to be inserted into in a mating connection manner. Both connecting slots 24 are connected to the cavity 23 by through holes 25. The cavity 23 contains two symmetrically arranged spring pin structures. Each spring pin structure corresponds to one of the two connecting plates 21. Each spring pin structure includes a sleeve 26, a pin rod 27, and a fixing plate 28. The fixing plate 28 is integrally formed on the inner wall of the cavity 23, and the sleeve 26 is fixed to the fixing plate 28 by bolts. One end of the pin rod 27 slides through the through hole 25 and is inserted into the insertion hole 22 in a mating connection manner. The other end of the pin rod 27 slides into the sleeve 26 and is bonded and fixedly connected to the inner bottom wall of the sleeve 26 with a spring body 29. In this embodiment, a cover plate for covering the cavity 23 can be fixed to the top of the rotating frame 45 by bolts. The output shaft of the rotary motor 6 is connected to the cover plate. Opening the cover plate facilitates the installation of the spring pin structure and the drive structure into the cavity 23.

[0045] The rotating frame 45 is also equipped with two drive structures. The two drive structures correspond to the two pins 27 respectively. The drive structures are used to drive the pins 27 to move into the sleeve 26, thereby pulling the pins 27 out of the insertion hole 22 and compressing the spring 36 body 29.

[0046] The drive structure includes an active block 30 and a passive block 31. The passive block 31 is fixedly sleeved on the outside of the pin 27 and slides left and right along the cavity wall of the cavity 23, with a first inclined surface 32 on the side opposite to the sleeve 26. The active block 30 has a through groove 33 extending laterally, and a second inclined surface 34 matching the first inclined surface 32 is provided on the side near the sleeve 26. The active block 30 slides back and forth along the cavity wall of the cavity 23 and is slidably sleeved on the outside of the pin 27 through the through groove 33. A connecting rod 35 is fixedly connected between the rear ends of the two active blocks 30. Two compression springs 36 are bonded and fixedly connected between the rear side of the middle position of the connecting rod 35 and the cavity wall of the cavity 23. A pressing block 37 is fixedly fixed to the front side of the middle position of the connecting rod 35. The front end of the pressing block 37 extends out of the rotating frame 45 in a slidable connection manner. In this embodiment, the passive block 31 and the pin rod 27 are integrally formed, and the connecting rod 35 is fixed to the active block 30 by bolts and nuts.

[0047] Additionally, the bottom end of the upper splicing ring 11 is provided with a second insertion groove 38, and the top end of the lower splicing ring 16 is integrally formed with a second insertion ring 39 for inserting into the second insertion groove 38 in a mating connection manner. When the upper splicing ring 11 and the lower splicing ring 16 are spliced, the second insertion ring 39 is inserted into the second insertion groove 38, improving the sealing performance when the upper splicing ring 11 and the lower splicing ring 16 are spliced.

[0048] Both the first insertion groove 17 and the second insertion groove 38 have annular rubber gaskets bonded and fixed to their groove walls. The annular rubber gaskets further improve the sealing performance when the upper splicing ring 11 and the lower splicing ring 16 are spliced.

[0049] Working principle:

[0050] When the bristles 20 in the brush plate need to be replaced due to wear, stains, and bacterial growth after prolonged use, open the switch door 10, and then move the rotating frame 45 and the brush plate to the position corresponding to the window via the reciprocating motor 1.

[0051] Next, the operator presses the pressing block 37 with their finger. The pressing block 37 drives the connecting rod 35 to move backward, compressing the spring 36 and creating a rebound force. Simultaneously, the connecting rod 35 drives two drive structures, thereby driving the two pins 27. The principle of the drive structures driving the pins 27 is as follows: the connecting rod 35 drives the active block 30 to move backward, and the second inclined surface 34 presses against the first inclined surface 32. The pressure on the first inclined surface 32 can be decomposed into a force acting towards the inside of the sleeve 26. Under the action of this force, the passive block 31 moves towards the sleeve 26. The passive block 31 drives the pins 27 to move into the sleeve 26. At the same time, the end of the pin 27 that was originally inserted into the insertion hole 22 is pulled out of the insertion hole 22. Once the pin 27 is completely pulled out of the socket 22, the connecting plate 21 is no longer fixed in the connecting groove 24. Pull the connecting plate 21 out of the connecting groove 24, and the brush plate can be removed from the bottom of the rotating frame 45.

[0052] Similarly, when a new brush plate needs to be installed at the bottom of the rotating frame 45, first press the pressing block 37 to retract the pin rod 27 into the cavity 23 and the through hole 25. Then insert the connecting plate 21 into the connecting groove 24. When the connecting plate 21 is fully inserted into the connecting groove 24, the insertion hole 22 and the through hole 25 correspond. Next, release the pressing block 37. Under the rebound force of the spring body 29 and the compression spring 36, the pin rod 27 returns to its original position. The end of the pin rod 27 that is away from the sleeve 26 passes through the through hole 25 and inserts into the insertion hole 22, thereby fixing the connecting plate 21 in the connecting groove 24. The brush plate can then be stably installed at the bottom of the rotating frame 45.

[0053] When it is necessary to clean the filter screen 44 and the inner wall of the extraction cylinder, the lower part 9 is moved downward by the lifting device 18, which can separate the extraction cylinder into the upper part 8 and the lower part 9, thus facilitating the cleaning of the inner wall of the extraction cylinder. After the upper part 8 and the lower part 9 are separated, the filter screen 44 can be removed from the lower splicing ring 16, making it easy to clean the filter screen 44. The lower part 9 is moved upward by the lifting device 18 until the first insertion ring 13 is fully inserted into the first insertion slot 17, thus splicing the upper part 8 and the lower part 9 to form a complete extraction cylinder.

[0054] This invention allows for the replacement of the brush plate, and the process of disassembling and assembling the brush plate is simple and convenient.

[0055] Example 2:

[0056] The difference from Embodiment 1 is that the driving structure no longer includes the active block 30 and the passive block 31, and correspondingly, the first inclined surface 32, the second inclined surface 34, the connecting rod 35, and the pressing block 37 are no longer provided. Instead, it is as follows: Figure 6 and Figure 7 As shown, the drive structure includes a slide groove 40, a slider 41, and a slide plate 42. The slide groove 40 is formed on the front outer side wall of the rotating frame 45, communicates with the cavity 23, and extends laterally to the left and right. The slider 41 slides left and right along the slide groove 41. One end of the slider 41 passes into the cavity 23 and is fixedly connected to the pin 27. The other end of the slider 41 passes out of the rotating frame 45 and is fixedly connected to the slide plate 42. A retaining plate 43 is fixed to one end of each of the two slide plates 42. The slider 41, the pin 27, and the slide plate 42 are all fixed together by bolts, and the retaining plate 43 and the slide plate 42 are integrally formed.

[0057] When the drive mechanism needs to move the pin 27 into the sleeve 26, the operator presses the two locking plates 43 with two fingers, causing them to move towards each other. This simultaneously drives the two drive mechanisms, thus simultaneously moving the two pins 27. The principle of the drive mechanism driving the pins 27 is as follows: the locking plate 43 drives the sliding plate 42, the sliding plate 42 drives the slider 41 to move along the slide groove 40, and the slider 41 drives the pin 27 to move.
