[0002] Camellia oil, also known as tea seed oil or oil tea seed oil, is a natural plant oil extracted from the seeds of the camellia tree. Due to its unique fatty acid composition and rich active ingredients, it has significant nutritional value. Cold pressing is a production process for camellia oil, generally carried out at temperatures below 60℃. Its advantage lies in its ability to fully preserve nutrients and active substances. Camellia oil is often extracted using hydraulic cold pressing, commonly achieved with hydraulic oil presses. Hydraulic oil presses primarily utilize hydraulic cylinders for pressing.

[0003] Currently, most hydraulic oil presses on the market require lifting the oil press cylinder after pressing camellia oil, and the oil cake that has been pressed out is taken out from the bottom of the cylinder. The process of removing the oil cake still relies on manual labor, which is time-consuming and laborious. Moreover, if the oil cake falls off the press during the discharge process, it will be contaminated with camellia oil, increasing the subsequent tedious processing.

[0004] Therefore, we have made improvements to this and proposed a constant pressure cold pressing device for camellia oil. Summary of the Invention

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments.

[0022] Example: Refer to Figures 1 to 7 A constant-pressure cold-pressing device for camellia oil is disclosed, mainly a hydraulic oil pressing device for cold pressing camellia oil. It includes a frame 100, a hydraulic oil pressing mechanism 101 mounted on the top of the frame 100, which applies downward pressing pressure. Lifting mechanisms 102 are respectively provided on both sides of the frame 100 to assist in removing the oil cake. A base 103 is located at the bottom of the frame 100, and a base 104 is mounted on the base 103. A bottom frame 200 is movably mounted on the base 104, and an upper frame 201 is fitted onto the bottom frame 200. The bottom frame 200 and the upper frame 201 are tubular structures with the same diameter, and both the bottom frame 200 and the upper frame 201 have oil outlet holes. A constant downward pressure is applied to the camellia oil material placed in the bottom frame 200 and the upper frame 201 by the hydraulic oil pressing mechanism 101, causing the camellia oil material to... The oil is discharged through the oil outlet, while the oil cake remains in the bottom frame 200 for subsequent discharge. The upper frame 201 moves vertically via a lifting mechanism 102 mounted on the frame 100. After pressing the oil, the upper frame 201 is lifted by the lifting mechanism 102, which facilitates the horizontal movement of the bottom frame 200. The lifting mechanism 102 can lift the upper frame 201 by making vertical movements through a linear module. The specific structure is not described in detail here. The bottom frame 200 moves horizontally via a linear drive mechanism 300 mounted at the bottom of the frame 100. The bottom of the bottom frame 200 is movably mounted with a receiving seat 203 for receiving waste material via a guide mechanism 400. The receiving seat 203 moves downward when it moves outside the frame 100 with the bottom frame 200 and resets when it moves back to the base 103 with the bottom frame 200. To address the problem in existing technologies where, after pressing camellia oil, the pressing cylinder needs to be lifted and the oil cake removed from the bottom, a process still requiring manual labor that is time-consuming and labor-intensive, this embodiment addresses this issue by using a bottom frame 200 with a movable receiving seat 203. After pressing, the oil cake falls onto the receiving seat 203 and moves out of the frame 100 along with the bottom frame 200. The receiving seat 203 moves downwards with the oil cake during this process, facilitating quick and easy manual removal of the oil cake and avoiding the need to remove it from the frame 100. This simplifies operation, improves the practicality of the cold pressing device, and enhances its overall functionality.

[0023] Furthermore, both sides of the top of the upper frame 201 have protruding plates 202 for the lifting mechanism 102 to ascend. The protruding plates 202 are located above the output end of the lifting mechanism 102, so that the upper frame 201 can be moved upward by the action of the protruding plates 202.

[0024] Furthermore, the linear drive mechanism 300 includes a threaded rod 301 mounted on one side of the frame 100. The side of the base frame 200 has a threaded seat 302 adapted to the threaded rod 301. The threaded seat 302 is threadedly engaged with the threaded rod 301. A transmission wheel 303 is mounted at the end of the threaded rod 301. The transmission wheel 303 is driven by a motor (not shown) mounted inside the frame 100 via a transmission belt 304. When oil cake needs to be discharged, the output of the motor, transmission belt 304, and transmission wheel 303 provides rotational power to the threaded rod 301. The rotation of the threaded rod 301... The moving thread seat 302 moves along its linear direction, thereby driving the bottom frame 200 and the receiving seat 203 to remove the oil cake from the frame 100. Correspondingly, the linear drive mechanism 300 also includes a slide rod 305 installed on the other side of the frame 100. The side of the bottom frame 200 has a slide seat 306 adapted to the slide rod 305. The slide rod 305 provides guidance for the linear movement of the thread seat 302 when the thread rod 301 rotates. It also facilitates the installation of the slide seat 306 on the other side of the bottom frame 200, so that the bottom frame 200 is subjected to force on both sides simultaneously, and the oil cake is moved out of the frame 100.

[0025] Furthermore, both the threaded seat 302 and the slide 306 are configured with a Z-shaped structure. The end of the threaded seat 302 near the end of the threaded rod 301 is threadedly engaged with the threaded rod 301, and the end of the slide 306 near the end of the slide rod 305 is slidably engaged with the slide rod 305. The advantage of this design is that when the threaded seat 302 moves from one end of the threaded rod 301 to the other end, the bottom frame 200 and the receiving seat 203 can move the oil cake out of the frame 100.

[0026] Furthermore, the base 104 is located in the middle of the base 103. The base 103 is provided with an oil receiving tray 600, which includes a frame plate 602 surrounding the base 103. The frame plate 602 has an outwardly extending oil outlet groove 601. During the oil pressing process by the hydraulic oil pressing mechanism 101, the oil discharged from the upper frame 201 and the bottom frame 200 is discharged outward through the oil receiving tray 600 for easy collection. Furthermore, the height of the bottom of the oil receiving tray 600 gradually decreases from the inside to the outside. The outer end of the oil outlet groove 601 extends to the outside of the base 103 and is lower on the outside and higher on the inside, which facilitates the automatic flow of oil for collection. The position of the oil outlet groove 601 is opposite to the direction of movement of the bottom frame 200. That is, the position for collecting camellia oil and the position for collecting oil cake are located on both sides of the frame 100, making the operation more flexible. The height of the frame plate 602 is lower than the height of the base 104 to avoid obstruction when the bottom frame 200 and the receiving seat 203 are moved out of the frame 100.

[0027] Furthermore, the guiding mechanism 400 includes a guide seat 401 fixed to the inner side of the frame 100. The guide seat 401 is provided with a guide groove 402 for the displacement of the receiving seat 203. Preferably, the guide groove 402 includes a linear groove and an inclined groove with a lower outer side and a higher inner side. The connection between the inclined groove and the linear groove is smoothly connected. The height between the outer end and the inner end of the inclined groove is greater than the height of the oil cake after pressing. A connecting rod 403 is fixed to the side of the receiving seat 203. A roller bearing 404 adapted to the guide groove 402 is installed on the top side of the connecting rod 403. The roller bearing 404 is used to reduce the friction when it moves in the guide groove 402. Specifically, during operation, the bottom frame 200 and the receiving seat 203 move outward from the frame 100 under the drive of the threaded rod 301 and the threaded seat 302. During the movement, the roller bearing 404 enters the guide groove 402, and when entering the inclined groove, the roller bearing 404, the connecting rod 403, and the receiving seat 203 move down synchronously with the oil cake due to the squeezing of the inner wall of the inclined groove. When the bottom frame 200 moves to the outside of the frame 100, the oil cake moves completely down to the outside of the bottom frame 200 along with the receiving seat 203. Therefore, when removing the oil cake, the relevant operator only needs to push it off the receiving seat 203 from one side. The structure is simple, the operation is convenient, and the practicality of the oil pressing device is improved.

[0028] Furthermore, both sides of the bottom frame 200 have connecting seats 500, and the ends of the threaded seat 302 and the slide 306 are provided with movable grooves 501. A guide post 502 is provided within the movable groove 501. The connecting seat 500 extends into the movable groove 501 and is inserted into the guide post 502. An elastic element 503 is provided between the bottom of the connecting seat 500 and the inner wall of the movable groove 501. The movable groove 501 provides space for the bottom frame 200 to float up and down. Specifically, during the process of removing and resetting the oil cake, the bottom frame 200 and the receiving seat 203 will move upwards due to the action of the elastic element 503 after the oil cake is removed. The bottom of the upper frame 201 is higher than the height of the base 103, which facilitates the reset of the bottom frame 200 and the support seat 203 on the base 103 and makes them coaxial with the raised upper frame 201. Furthermore, the width of the guide groove 402 relative to the base 104 is greater than the diameter of the roller bearing 404, providing space for the support seat 203 to move. Specifically, after the upper frame 201 is reset, the upper frame 201 presses the lower frame into close contact with it, and the support seat 203 moves down into close contact with the base 104 under the pressure of the upper frame 201 and the lower frame, so that the base 103 provides support for the support seat 203 during the oil pressing operation of the hydraulic oil pressing mechanism 101.

[0029] The process of using the camellia oil constant pressure cold pressing device provided by this invention is as follows: Camellia oil raw materials are filled into the bottom frame 200 and the upper frame 201. The hydraulic oil pressing mechanism 101 is driven by an external machine box. The output end of the hydraulic oil pressing mechanism 101 has an oil pressing plate. The hydraulic oil pressing mechanism 101 applies a constant pressure to the camellia oil raw materials in the bottom frame 200 and the upper frame 201. The oil in the camellia oil raw materials is pressed out and discharged from the oil outlet holes on the bottom frame 200 and the upper frame 201 respectively, falling into the oil receiving tray 600. Through the guiding action of the oil receiving tray 600, the camellia oil is discharged outward through the oil outlet groove 601 and collected. The cold pressing process of camellia oil requires low temperature to preserve the nutrients and natural flavor of the oil. The hydraulic oil press can effectively extract oil without generating high temperature through static pressing, which meets the requirements of the cold pressing process. After oil pressing, the camellia oil raw material is compressed into an oil cake and placed on the receiving seat 203 at the lower end of the bottom frame 200. At this time, the external machine housing drives the hydraulic oil pressing mechanism 101 to reset and drives the lifting mechanism 102 to lift the upper frame 201, separating the upper frame 201 from the bottom frame 200. Then, the machine housing drives the linear drive mechanism 300 to work. The threaded rod 301 rotates and, under the guidance of the slide rod 305, the threaded seat 302 moves linearly along the threaded rod 301, thereby carrying the bottom frame 200 and the receiving seat 203 to bring the oil cake out of the machine frame 100. During this process, the roller bearing 404 is squeezed when it enters the inclined groove in the guide groove 402, and moves downward along with the receiving seat 203 and the oil cake. When the bottom frame 200 moves outside the frame 100 and the threaded seat 302 stops moving, the oil cake moves completely outside the bottom frame 200 along with the receiving seat 203. Then, when removing the oil cake, the relevant operator only needs to push it off the receiving seat 203 from one side. The structure is simple and the operation is convenient, which improves the practicality of the oil pressing device. Correspondingly, when the bottom frame 200 is reset, the threaded rod 301 rotates in the opposite direction.
