Detailed Implementation

[0027] like Figures 1-7 As shown, this invention discloses a camellia oil pressing device, comprising a support base 1 and a cylindrical shell 2 fixed on the support base 1. The support base 1 includes a platform plate and four support legs installed below the platform plate. This provides stable support for the entire device during use. The axis of the cylindrical shell 2 is vertically aligned, and its lower end is fixed to the support base 1. A pressure plate 3, circular in shape, is slidably sealed on the upper side of the cylindrical shell 2. As the pressure plate 3 moves up and down, it compresses the space inside the cylindrical shell 2.

[0028] The center of the pressing plate 3 is rotationally connected with a center shaft 4, the center shaft 4 is coaxial with the cylindrical shell 2, the upper limiting plate 5 and the lower limiting plate 6 are connected on the center shaft 4 on the two sides of the pressing plate 3, the upper limiting plate 5 and the lower limiting plate 6 are both circular, and the upper limiting plate 5 and the lower limiting plate 6 are respectively used for limiting the upper side and the lower side of the pressing plate 3. The center shaft 4 is connected to the output end of the motor 7, the motor 7 is connected to the output end of the telescopic device 8, and the telescopic device 8 is fixed to the lower side of the support base 1. In particular, the motor 7 drives the center shaft 4 to rotate, and since the center shaft 4 is rotationally connected with the pressing plate 3, the center shaft 4 cannot drive the pressing plate 3 to rotate. However, under the limiting action of the upper limiting plate 5 and the lower limiting plate 6, the center shaft 4 can drive the pressing plate 3 to move up and down to realize the pressing of camellia oil when moving along the vertical direction. The power for the up and down movement is realized through the telescopic device 8, and the telescopic device 8 can be an existing oil cylinder, which directly drives the motor 7 and the center shaft 4 connected thereto to move up and down.

[0029] Further, a plurality of through holes 9 are uniformly distributed on the pressing plate 3, each group of through holes 9 is two, a plug column 10 is slidably arranged in the through hole 9, the two ends of the plug column 10 are respectively extended from the upper and lower ends of the through hole 9, the lower end of the plug column 10 is fixedly connected to an extrusion block 11, and the first spring 12 is connected between the extrusion block 11 and the pressing plate 3. The upper end of the center shaft 4 is fixedly connected with a rotating shaft 13, the rotating shaft 13 is arranged along the radial direction of the center shaft 4, the outer end of the rotating shaft 13 is rotationally connected with a roller 14, and the roller 14 can abut against the upper end of the plug column 10. When the roller 14 rolls along the circumference of the center shaft 4, the outer surface of the roller 14 can roll and press the plug column 10, so that the plug column 10 moves downward to extrude the camellia oil seeds in a small area, and the oil extraction can be further realized. In order to improve the sealing performance of the plug column 10, a sealing ring can be mounted on the outer side of the plug column 10, and the sealing ring is in sealing cooperation with the inner wall of the through hole 9.

In order to improve the compression degree of the camellia oil seeds, the inner air outlet pipe 15 and the outer air outlet pipe 16 are both made of rubber material and can be further compressed. In work, the hot air machine is used to provide hot air for the hot air chamber 18, the air in the hot air chamber 18 is discharged into the pressing cavity through the air outlet hole 17, the temperature of the camellia oil seeds can be improved, the cell wall of the camellia oil seeds can be more easily broken, and the oil extraction rate can be improved. By adopting the cylindrical mode, the space occupied can be avoided, and the pressing plate 3 can be normally compressed. By arranging the air outlet pipes in the middle part of the camellia oil seeds, the camellia oil seeds can be heated from the inside to the outside, and the uniformity of heating is better.

[0031] In the embodiment, the upper surface of the hot air chamber 18 is formed as a taper surface with the upper part being smaller than the lower part, which can be used to guide the oil to be discharged downward. The lower end of the outer air pipe 16 is provided with a sealing diaphragm 19, one end of the sealing diaphragm 19 is connected with the outer air pipe 16, and the other end seals the outer air pipe 16 under the elastic force of the sealing diaphragm 19. At this time, the hot air chamber 18 can be separated from the outside to prevent the camellia oil from entering. The sealing diaphragm 19 can be pried open after the inner air pipe 15 is inserted into the outer air pipe 16, so that the hot air can be normally introduced to heat the camellia oil seeds.

[0032] In the embodiment, each extrusion block 11 corresponds to two insertion columns 10, which can increase the stability of the structure. The first spring 12 is sleeved outside the insertion column 10. When the roller 14 rolls along the circumference of the central shaft 4, the insertion column 10 can be crushed, so that the insertion column 10 moves downward to extrude the camellia oil seeds with a small area.

The heating ring plates 22 are connected with heating wires, and each heating ring plate 22 is connected by a support rod 23 arranged along the vertical direction. The lower end of the support rod 23 is fixed on the support base 1. By arranging the heating device on the outer side of the cylindrical shell 2, the camellia oil seeds can be further heated to increase the oil yield.

[0035] In the embodiment, the upper surface of the pressing plate 3 is circumferentially distributed with a plurality of first tooth blocks 24, and a through hole 9 is formed in a tooth slot formed between two adjacent first tooth blocks 24.

[0036] In the embodiment, the upper end of the insertion column 10 is formed as a spherical structure, which can facilitate the cooperation between the insertion column 10 and the surface of the roller 14 to prevent damage to the roller 14.

[0037] In the embodiment, the outer side of the central shaft 4 is sleeved with a sleeve 26, the inner side of the sleeve 26 is uniformly provided with vertical grooves 27, and the outer side of the central shaft 4 is provided with vertical ribs 28 corresponding to the vertical grooves 27; the sleeve 26 is connected with the upper limiting plate 5 through a second spring 29, and the second spring 29 is installed in the installation groove 30 formed on the lower side of the sleeve 26.
