[0053] The present invention will now be described in further detail with reference to the accompanying drawings.

[0054] like Figures 1 to 3 As shown below, the steps and functions of a rapeseed oil pressing method are explained in detail.

[0055] A method for pressing rapeseed oil, the method comprising the following steps:

[0056] S1: Drive multiple processing cylinders 31 to rotate, so that the multiple processing cylinders 31 pass through the unloading station, the extrusion station and the discharge station in sequence;

[0057] S2: When the processing cylinder 31 moves to the unloading station, the rapeseed falls into the processing cylinder 31;

[0062] S22: The inclined extrusion roller 53, which slides inside the processing cylinder 31, moves to the lower side of the notch 32;

[0063] S23: With the inclined surface of the inclined extrusion roller 53 facing upward, the rapeseed falls into the notch 32 and contacts the inclined extrusion roller 53 before entering the processing cylinder 31;

[0064] S3 specifically includes the following steps:

[0065] S31: The notch 32 on the machining cylinder 31 moves to the side;

[0066] S32: The inclined extrusion roller 53 sliding inside the processing cylinder 31 extrudes the rapeseed;

[0067] S33: Inclined extrusion roller 53 and extrusion plate 42 extrude rapeseed to form rapeseed oil;

[0068] S4 specifically includes the following steps:

[0069] S41: The notch 32 on the machining cylinder 31 moves to the lower side;

[0070] S42: The inclined extrusion roller 53, which slides inside the processing cylinder 31, moves to the lower side of the notch 32;

[0071] S43: The inclined surface of the inclined extrusion roller 53 faces downward, and the rapeseed residue is discharged from the processing cylinder 31 through the notch 32.

[0072] A rapeseed oil comprising, by weight, the following ingredients: 60 to 80 parts rapeseed oil; 12 to 13 parts honeysuckle; 2 to 3 parts goji berries; 3 to 4 parts loquat leaves; 6 to 7 parts hawthorn; 1 to 1.5 parts peppermint; and 12 to 15 parts tea oil.

[0073] like Figures 4 to 12 As shown, in order to facilitate the implementation of a rapeseed oil pressing method, a rapeseed oil pressing device is designed. The structure and function of the rapeseed oil pressing device are described in detail below.

[0074] A rapeseed oil pressing device includes a device support 11, four arc tracks I 12 fixedly connected to the device support 11, and a storage cavity 13 fixedly connected to the device support 11.

[0075] Each of the four circular arc tracks I12 is rotatably connected to two conversion rings 21. Each conversion ring 21 is fixedly connected to multiple mounting seats 22. The device bracket 11 is rotatably connected to four drive gears 23, which mesh with the two conversion rings 21 respectively for transmission.

[0076] A power mechanism I for driving the drive gear 23 to rotate is fixedly connected to the device bracket 11. The power mechanism I is preferably a servo motor.

[0077] A processing cylinder 31 is fixedly connected between multiple mounting seats 22 on the two conversion rings 21, and each processing cylinder 31 is provided with a notch 32;

[0078] Each processing cylinder 31 is fixedly connected to a telescopic mechanism I 41, and each telescopic mechanism I 41 is fixedly connected to a pressing plate 42. The pressing plate 42 is provided with multiple pressing holes, and the multiple pressing plates 42 are slidably connected in the multiple processing cylinders 31 respectively.

[0079] Each processing cylinder 31 is fixedly connected to a telescopic mechanism II 51, and each telescopic mechanism II 51 is rotatably connected to a drive shaft 52. Each drive shaft 52 is fixedly connected to an inclined extrusion wheel 53, and multiple inclined extrusion wheels 53 are respectively fitted with clearance within multiple processing cylinders 31.

[0080] Each telescopic mechanism II 51 is fixedly connected to a power mechanism II that drives the drive shaft 52 to rotate. The power mechanism II is preferably a servo motor.

[0081] When using, such as Figure 5 As shown, the upper side of the conversion ring 21 is set as the extrusion station, the left side of the conversion ring 21 is set as the discharge station, and the right side of the conversion ring 21 is set as the unloading station. When the power mechanism I is started, the output shaft of the power mechanism I starts to rotate. The output shaft of the power mechanism I drives the drive gear 23 to rotate, the drive gear 23 drives the conversion ring 21 to rotate, and the conversion ring 21 drives multiple processing cylinders 31 to move, so that the multiple processing cylinders 31 pass through the unloading station, the extrusion station and the discharge station in sequence.

[0082] When the processing cylinder 31 moves to the unloading station, such as Figure 10 As shown, at this time, the notch 32 moves to the upper side of the processing cylinder 31, and the inclined extrusion wheel 53 moves to the lower side of the notch 32. The inclined surface of the inclined extrusion wheel 53 faces upward, and the rapeseed falls into the notch 32 and contacts the inclined extrusion wheel 53 to enter the processing cylinder 31.

[0083] When the processing cylinder 31 moves to the extrusion station, the telescopic mechanism II 51 and the telescopic mechanism I 41 are activated. The telescopic end of the telescopic mechanism I 41 drives the extrusion plate 42 to move, so that the extrusion plate 42 moves to the front end of the inner side of the processing cylinder 31. The telescopic end of the telescopic mechanism II 51 drives the inclined extrusion wheel 53 to move, so that the inclined extrusion wheel 53 extrudes the rapeseed. The rapeseed oil in the rapeseed is discharged through multiple extrusion holes provided on the extrusion plate 42 and falls into the collection cavity 13.

[0084] Furthermore, during extrusion, power mechanism II can be activated, and the output shaft of power mechanism II begins to rotate. The output shaft of power mechanism II drives drive shaft 52 to rotate, and drive shaft 52 drives tilting extrusion wheel 53 to rotate. Tilting extrusion wheel 53 rotates inside processing cylinder 31.

[0085] When the processing cylinder 31 moves to the discharge station, the notch 32 on the processing cylinder 31 moves to the lower side, activating the telescopic mechanism II 51 and the telescopic mechanism I 41. The telescopic mechanism II 51 and the telescopic mechanism I 41 can be hydraulic cylinders or electric push rods. The telescopic ends of the telescopic mechanism II 51 and the telescopic mechanism I 41 respectively drive the inclined extrusion wheel 53 and the extrusion plate 42 to move. The inclined surface of the inclined extrusion wheel 53 faces downward. The inclined extrusion wheel 53 and the extrusion plate 42 drive the rapeseed residue to the upper side of the notch 32. The rapeseed residue is discharged from the processing cylinder 31 through the notch 32.

[0086] Furthermore, such as Figure 12 As shown, in order to make the above process work automatically, multiple sensors 24 are fixedly connected to both conversion rings 21. The multiple sensors 24 on one conversion ring 21 are respectively connected to multiple telescopic mechanisms I 41, and the multiple sensors 24 on the other conversion ring 21 are respectively connected to multiple telescopic mechanisms II 51.

[0087] Two mounting brackets 61 are fixedly connected to the device bracket 11. Multiple telescopic mechanisms Ⅲ 62 are fixedly connected to each mounting bracket 61. A circular arc track Ⅱ 63 is fixedly connected to the telescopic end of each telescopic mechanism Ⅲ 62. A circular arc pressure plate 64 is slidably connected to each circular arc track Ⅱ 63.

[0088] The arc-shaped pressure plate 64 is connected to a positioning pin by a thread. The inner side of the positioning pin can press against the arc-shaped track II 63, and the positioning pin positions the arc-shaped pressure plate 64.

[0089] Multiple arc-shaped pressure plates 64 on the two mounting brackets 61 can respectively contact multiple sensors 24 on the two conversion rings 21;

[0090] In use, the sensor 24 is connected to the telescopic mechanism I 41 or the telescopic mechanism II 51 through the electronic control means commonly used in the art. The sensor 24 can be a contact sensor or a compression sensor. When the sensor 24 is compressed, the sensor 24 controls the corresponding telescopic mechanism I 41 or the telescopic mechanism II 51 to move.

[0091] like Figure 5 As shown, there are four processing cylinders 31, four telescopic mechanisms I 41 and four telescopic mechanisms II 51, and eight sensors 24. The sensors 24 are connected to the four telescopic mechanisms I 41 and the four telescopic mechanisms II 51 respectively.

[0092] Eight arc-shaped pressure plates 64 are set up, each of which can contact eight sensors 24. The telescopic mechanism Ⅲ 62 is activated. The telescopic mechanism Ⅲ 62 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism Ⅲ 62 drives the arc-shaped track Ⅱ 63 to move. The arc-shaped track Ⅱ 63 drives the arc-shaped pressure plates 64 to move, thereby controlling whether the arc-shaped pressure plates 64 can contact the sensors 24. That is, when the sensors 24 move to the designated position, whether they can contact the arc-shaped pressure plates 64, and whether the corresponding telescopic mechanism Ⅰ 41 and telescopic mechanism Ⅱ 51 are controlled to work.

[0093] Furthermore, the arc pressure plate 64 is set with different curvatures, thereby controlling the time when the arc pressure plate 64 contacts the sensor 24 and the sensor 24 is squeezed, thereby controlling the distance of movement of the telescopic ends of the telescopic mechanism I 41 and the telescopic mechanism II 51.

[0094] Furthermore, the arc-shaped pressure plate 64 can slide on the arc-shaped track II 63. The position of the arc-shaped pressure plate 64 is fixed by the positioning pin, thereby controlling which position the sensor 24 will contact the arc-shaped pressure plate 64 after moving.

[0095] When the conversion ring 21 rotates and drives the four processing cylinders 31 to move, when the processing cylinder 31 moves to the material dropping operation, the corresponding telescopic mechanism I 41 and telescopic mechanism II 51 do not move. At this time, the notch 32 moves to the upper side of the processing cylinder 31, and the inclined extrusion wheel 53 moves to the lower side of the notch 32. The inclined surface of the inclined extrusion wheel 53 faces upward, and the rapeseed falls into the notch 32 and contacts the inclined extrusion wheel 53 to enter the processing cylinder 31.

[0096] The arc-shaped pressure plate 64 at this position is pre-adjusted so that after the material is unloaded, the arc-shaped pressure plate 64 contacts the sensor 24 corresponding to the telescopic mechanism II 51, so that the sensor 24 controls the telescopic end of the telescopic mechanism II 51 to drive the inclined extrusion wheel 53 to move a certain distance, and the inclined extrusion wheel 53 seals the notch 32.

[0097] When the processing cylinder 31 moves to the extrusion station, the two sensors 24 at the corresponding positions are squeezed by the arc pressure plate 64. The telescopic end of the telescopic mechanism I 41 drives the extrusion plate 42 to move, so that the extrusion plate 42 moves to the front end of the inner side of the processing cylinder 31. The telescopic end of the telescopic mechanism II 51 drives the inclined extrusion wheel 53 to move, so that the inclined extrusion wheel 53 squeezes the rapeseed. The rapeseed oil in the rapeseed is discharged through the multiple extrusion holes set on the extrusion plate 42 and falls into the collection cavity 13.

[0098] When the processing cylinder 31 moves to the discharge station, the notch 32 on the processing cylinder 31 moves to the lower side, and the two sensors 24 at the corresponding positions are squeezed by the arc pressure plate 64. The telescopic ends of the telescopic mechanism II 51 and the telescopic mechanism I 41 respectively drive the inclined extrusion wheel 53 and the extrusion plate 42 to move. The inclined surface of the inclined extrusion wheel 53 faces downward. The inclined extrusion wheel 53 and the extrusion plate 42 drive the rapeseed residue to the upper side of the notch 32. The rapeseed residue is discharged from the processing cylinder 31 through the notch 32.

[0099] The arc-shaped pressure plate 64 at this position is pre-adjusted so that after the material is discharged, the arc-shaped pressure plate 64 contacts the sensor 24 corresponding to the telescopic mechanism I41, so that the sensor 24 controls the telescopic end of the telescopic mechanism I41 to drive the inclined extrusion plate 42 to move a certain distance, providing a certain space for the material to fall.

[0100] At this time, the inclined extrusion roller 53 moves to the lower side of the notch 32, and the inclined surface of the inclined extrusion roller 53 is also set to face downward. During the rotation, the notch 32 will move to the upper side, and the inclined surface of the inclined extrusion roller 53 will also move to the upper side, which facilitates material discharge. This cycle continues, and the device automatically completes the entire processing process.
