[0002] In the current technological process of betel nuts, there is a process of pressing seeds. Currently, a hydraulic baler or a cylindrical press is used to press the seeds, that is, a fixed number of betel nut round fruits are placed in a fixed space, and then the space is squeezed by hydraulic equipment, so that the betel nuts in the space are squeezed against each other to deform, so as to change the betel nuts from a rugby shape to a flat shape, and then cut from the flat surface into two pieces to obtain two pressed finished betel nut slices. The obtained betel nut slices have a flat opening and there are textures similar to lotus leaf edges on the cut edges, with a beautiful appearance, meeting the current market's aesthetic requirements for the appearance of finished betel nuts.

[0003] After retrieval, the patent number: "CN221128796U" discloses "A betel nut processing seed pressing and shaping die", which includes two relatively arranged detachable upper energy plates and lower energy plates. Multiple groups of pipelines are evenly distributed on the upper energy plates and the lower energy plates. The inlet end and the outlet end of the pipeline are provided with adapters. An even number of upper pattern cores are fixed in the upper energy plate by screws, and an even number of lower pattern cores are fixed in the lower energy plate by screws. The upper pattern cores and the lower pattern cores correspondingly cover and form multiple independent betel nut accommodating cavities. Multiple raised patterns imitating the surface of betel nuts are provided on the upper end wall and the lower end wall of the betel nut accommodating cavity.

[0038] Please refer to Figures 1 - 13The utility model provides a betel nut pattern forming mold, including an upper mold 1 and a lower mold 2, a plurality of first protrusions 3 are provided below the upper mold 1, an upper shaping curved surface 6 is provided below the first protrusions 3, a second protrusion 4 is provided above the lower mold 2, a plurality of accommodating grooves 5 are provided above the second protrusions 4, the size of the accommodating grooves 5 is adapted to the first protrusions 3, a lower shaping curved surface 7 is provided at the bottom of the accommodating grooves 5, the first protrusions 3 can extend into the accommodating grooves 5, a shaping structure is provided on the upper shaping curved surface and the lower shaping curved surface, and the upper shaping curved surface 6 cooperates with the lower shaping curved surface 7 to form a shaping cavity 8. By providing the accommodating groove 5, when the upper mold 1 is moved downward, the outer wall of the first protrusion 3 can gradually fit closely against the inner wall of the accommodating groove 5 and be embedded in the accommodating groove 5, so that the shaping cavity 8 temporarily forms a fully enclosed structure, which effectively prevents the betel nut from escaping from the shaping cavity 8 during the extrusion process and causing the betel nut seeds to be crushed, thereby greatly improving the yield rate of the seed pressing process and significantly reducing economic losses.

[0039] Specifically, the shaping structure 19 is any one of a sawtooth structure or a wavy structure fitted on the upper shaping curved surface 6 and the lower shaping curved surface 7 .

[0040] Specifically, the longitudinal cross-sectional shape of the molding cavity 8 fits any one of an M shape, an olive shape, a single fold line shape, a double fold line shape, a triple fold line shape, and a lightning symbol shape, which can be selected according to the shape requirements of the pressed betel nut; the transverse cross-sectional shape of the molding cavity 8 is a contour shape that is thick in the middle and thin on both sides, so that the olive-shaped betel nut that has not yet been pressed can automatically roll and be basically centered after being placed in.

[0041] The longitudinal overall shape of the molding cavity 8 can press the overall appearance of the betel nut into a large shape, and the molding structure 19 on the upper molding surface and the lower molding surface can shape various medium and small shapes similar to lotus leaves on the appearance of the betel nut, which conforms to the market aesthetics.

[0042] Specifically, at least one upper ventilation channel 9 is provided in the upper mold 1, one end of which leads to the center of the upper shaping surface 6, and the other end of which is connected to compressed air; at least one lower ventilation channel 10 is provided in the lower mold 2, one end of which leads to the center of the lower shaping surface 7, and the other end of which is connected to compressed air. After each seed pressing is completed, the compressed air can be automatically controlled by the program to blow off the betel nut seeds embedded in the lower shaping surface and the upper shaping surface, without manual removal one by one, which not only improves production efficiency, but also avoids direct manual contact with the upper mold 1 and the lower mold 2 in a heated state to prevent burns; further, the compressed air can be cooled before being sent into the ventilation channel, and the compressed betel nut seeds can be quickly cooled by compressed air to facilitate shaping of the betel nut seeds.

[0043] Specifically, it further includes two oppositely arranged upper temperature control plates 11 and lower temperature control plates 12. A plurality of temperature control pipes 13 are evenly arranged in the upper temperature control plates 11 and the lower temperature control plates 12. The plurality of upper molds 1 are fixedly connected to the lower surface of the upper temperature control plates 11, and the plurality of lower molds 2 are fixedly connected to the upper surface of the lower temperature control plates 12. By introducing hot water and steam into the temperature control pipes 13, the betel nuts can be effectively heated and insulated, ensuring the ductility of the betel nuts when they are pressed.

[0044] Furthermore, heat insulation plates 14 are attached to the outer side walls of the upper temperature control plates 11 and the lower temperature control plates 12. This can prevent heat loss through air transfer and, to a certain extent, avoid operators being scalded when accidentally touching the upper temperature control plates 11 and / or the lower temperature control plates 12.

[0045] Specifically, at least two limiting bumps 15 are provided on both the left and right sides of the accommodating groove 5. This can effectively ensure that the betel nuts are at the center of the lower shaping surface 7, further improving the qualified rate of the betel nut pressing process.

[0046] Specifically, at least two guiding columns 16 are vertically provided above the lower mold 2, and the upper mold 1 is correspondingly provided with guiding through holes 17. This further enhances the positioning when the upper mold 1 and the lower mold 2 cooperate, avoiding interference caused by the displacement of the upper mold 1 and the lower mold 2.

[0047] Specifically, at least two pressure limiting blocks 18 are provided below the upper mold 1. This increases physical limitation to prevent direct contact between the upper shaping surface 6 and the lower shaping surface 7 due to overpressure, thus preventing the upper shaping surface 6 and the lower shaping surface 7 from being damaged.

[0048] Specifically, the pressure limiting blocks 18 are detachably connected to the upper mold 1. According to betel nuts of different diameters, pressure limiting blocks 18 with different heights can be selected, improving the compatibility of the mold.

[0049] Working process and principle: The operator places the selected betel nuts at the center of the lower shaping surface 7 in the accommodating groove 5. Hot water or steam is introduced into the upper temperature control plate 11, and the downward pressing device is started. The downward pressing device presses the upper mold 1 downward and embeds it into the accommodating groove 5. The betel nuts are extruded by the upper shaping surface 6 and the lower shaping surface 7, causing the betel nuts to deform. After the betel nut pressing is completed, the valve of the compressed air is opened, and the betel nuts clinging to or embedded in the upper shaping surface and the lower shaping surface 7 are blown off by the compressed air. At the same time, the betel nuts are cooled to assist in shaping. Subsequently, the operator cleans, collects, and transports the shaped betel nuts to the next processing step, and starts a new round of betel nut pressing operation, and so on in a cycle.

[0050] The above are the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, making equivalent replacements or changes, shall be covered by the protection scope of the claims of the present utility model.
