Description

Technical Field

[0001] This invention relates to the technical field of peeling camellia fruit, and more particularly to a cutting and peeling tool for camellia fruit. Background Technology

[0002] Fresh camellia oleifera fruits vary in size and shape, with thick, hard shells and thin, brittle seed shells. Most existing shelling machines perform shelling after grading. However, the uncontrollable movement trajectory and stress on the fruits during shelling lead to low shelling rates, high seed breakage rates, and difficulty in separating the shell-seed mixture. To address this problem, a flat-laying, stepped cutting and shelling method is proposed. This method involves placing the camellia oleifera fruits into a hopper, which is then conveyed to the cutting and shelling area via a transmission belt. A cutter makes a circular cut on the fruit shell, and a slitting device completes the shelling process. The key to this method is designing a circular cutting tool for the camellia oleifera fruit shell. Summary of the Invention

[0003] Based on the flat-laying, stepped cutting method for shelling camellia fruit, a specialized cutting and shelling tool for camellia fruit was developed. This solves problems such as low shelling rate, high seed breakage rate, and difficulty in sorting the small differences between shells and seeds, achieving a highly efficient, cost-effective, simple, and easy-to-operate camellia fruit shelling process.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention.

[0037] In addition to the above, the present invention also has the following embodiments:

[0038] In a further embodiment of the present invention, a camellia oil cutting and peeling tool includes: a short blade 1, a medium blade 2, a tall blade 3, an L-shaped rib 4, a long rib 5, a side connecting plate 6, and a welding nut 7. The short blade 1, medium blade 2, and tall blade 3 all have cutting edges, the dimensions of which are shown in the drawings. Figure 3 As shown, the blade can cut through the outer skin of the camellia seed pod, preventing the seeds from being crushed during the shelling process; to prevent the camellia seed from slipping relative to the blade during movement, a square notch is provided on the blade, such as... Figure 3 As shown, the shape of the camellia fruit is changed; long strip openings are provided on L-rib plate 4 and long rib plate 5. Figure 4 As shown, the blades can be inserted to provide positioning and increase strength. The short blade 1, medium blade 2, and tall blade 3 are arranged in a stepped manner to cut the skin of camellia fruits of different sizes, achieving stepped cutting of the camellia fruit skin. Since the short blade 1 and medium blade 2 are mainly used to cut relatively larger camellia fruits, the final design spacing is 13mm after testing. The tall blade 3 is mainly used to cut relatively smaller camellia fruits, and the final design spacing is 8mm after testing.

[0039] In a further embodiment of the present invention, a stepped blade distribution method is adopted, which eliminates the need for multi-stage sorting before the camellia oleifera is shelled, reduces the number of operation steps, greatly improves production efficiency, and reduces the production cost of shelling camellia oleifera.

[0040] In a further embodiment of the present invention, the pre-pressing dehulling after cutting with a knife avoids the problem of crushing the camellia seeds by the rubbing and tearing method, thus reducing the breakage rate.

[0041] In a further embodiment of the present invention, a square notch is provided on the blade to change its posture during the cutting process, preventing the camellia fruit from sliding relative to the blade and achieving rolling circular cutting.

[0042] In a further embodiment of the present invention, the multiple short blades 1, multiple medium blades 2, and multiple tall blades 3 are connected by a slope transition. The conveying device for the camellia fruit is mostly a conveyor belt. The distance between the blades of the multiple tall blades 3 and the upper surface of the conveyor belt is smaller than the distance between the blades of the multiple medium blades 2 and the upper surface of the conveyor belt. The distance between the blades of the multiple medium blades 2 and the upper surface of the conveyor belt is smaller than the distance between the blades of the multiple short blades 1 and the upper surface of the conveyor belt. The camellia fruit is placed on the upper surface of the conveyor belt and conveyed from one side of the multiple short blades 1 to one side of the multiple tall blades 3. Smaller camellia fruits are moved to the multiple tall blades after passing under the multiple short blades 1 and the multiple medium blades 2. Below slice 3, medium-sized camellia fruits pass through multiple short blades 1 and then enter under multiple medium blades 2. Due to the small distance between the blades of multiple tall blades 3 and the upper surface of the conveyor belt, the camellia fruits roll on the conveyor belt and cannot move under the multiple tall blades 3. Larger camellia fruits enter under multiple short blades 1. Due to the large size of the camellia fruits, they roll on the conveyor belt and cannot move under the multiple medium blades 2. After the camellia fruits are sorted by multiple short blades 1, multiple medium blades 2 and multiple tall blades 3, the cutting tool moves down and cuts the camellia fruits located below it by multiple short blades 1, multiple medium blades 2 and multiple tall blades 3 respectively.

[0043] In a further embodiment of the present invention, by adjusting the downward depth of the cutting tool, the degree of damage to the camellia seeds by the cutting tool is reduced, thereby reducing the breakage rate.

[0044] In a further embodiment of the present invention, a method of cutting the camellia fruit to obtain camellia seeds is used instead of the existing rubbing and tearing method, which effectively reduces the breakage rate of camellia seeds.

[0045] In a further embodiment of the present invention, the blades of the plurality of short blades 1, the plurality of medium blades 2 and the plurality of tall blades 3 are all provided with square notches, which can effectively prevent the camellia fruit from rotating during the cutting process and reduce the breakage rate of the camellia seeds.

[0046] In a further embodiment of the present invention, multiple short blades 1 are connected and limited by multiple long ribs 5 to ensure that the backs of the multiple short blades 1 are located on a uniform horizontal plane, multiple medium blades 2 are connected and limited by multiple long ribs 5 to ensure that the backs of the multiple medium blades 2 are located on a uniform horizontal plane, and multiple tall blades 3 are connected and limited by multiple long ribs 5 to ensure that the backs of the multiple tall blades 3 are located on a uniform horizontal plane.

[0047] In a further embodiment of the present invention, a plurality of first embedding mounting grooves are provided on the back of a plurality of short blades 1, a plurality of medium blades 2 and a plurality of tall blades 3, and a plurality of second embedding mounting grooves are provided on a plurality of long ribs 5 and a plurality of L-ribs 4, with each first embedding mounting groove matching a second embedding mounting groove.

[0048] In a further embodiment of the present invention, at least one L-rib plate 4 is provided at the connection between the plurality of short blades 1 and the plurality of medium blades 2 to ensure that the backs of the plurality of short blades 1 and the backs of the plurality of medium blades 2 are located on the same horizontal plane. At least one L-rib plate 4 is provided at the connection between the plurality of tall blades 3 and the plurality of medium blades 2 to ensure that the backs of the plurality of tall blades 3 and the backs of the plurality of medium blades 2 are located on the same horizontal plane.

[0049] In a further embodiment of the present invention, the short blade 1, medium blade 2 and tall blade 3 located at the ends are all connected to the side connecting plate 6 by a plurality of welding nuts 7, so as to ensure the stability of the installation of the plurality of short blades 1, medium blades 2 and tall blades 3.
