Problems solved by technology

On the one hand, the clams and giant clams are nationally and locally protected aquatic animals. If they are used to prepare bead cores, it is not allowed by the animal protection law; on the other hand, the processing performance of the shells of the clams and giant clams Poor, prone to breakage during processing

Embodiment 1

[0019] Embodiment 1 is prepared according to the following steps:

[0020] (1) Cut into pieces: use a cutting machine to cut the unbalanced clam shells into pieces first, then cut the pieces into strips, and finally cut the strips into squares. The process allowance of this step is 1.2±0.3 mm; The spacing is 0.5 mm, and the squares are sorted by size with a sieve machine;

[0021] (2) Chamfering: Put the sorted cubes into the chamfering machine for chamfering. The loading volume is: the volume of the sorted cubes accounts for 1 / 5 of the volume of the chamfering machine barrel, and the chamfering machine is turned on 2 min, to prepare rough embryos;

[0022] (3) Rounding: the rough grinding, medium grinding and fine grinding are carried out in turn to obtain finely ground bead nuclei; the processes adopted for the coarse grinding, medium grinding and fine grinding are respectively as follows:

[0023] ① Coarse grinding: Evenly spread the blanks on the grinding disc of the gri...

Embodiment 2

[0030] Embodiment 2 is prepared according to the following steps:

[0031] (1) Cut into pieces: use a cutting machine to cut the unbalanced clam shells into pieces first, then cut the pieces into strips, and finally cut the strips into squares. The process allowance of this step is 1.2±0.3 mm; The spacing is 0.5 mm, and the squares are sorted by size with a sieve machine;

[0032] (2) Chamfering: Put the sorted cubes into the chamfering machine for chamfering. The loading volume is: the volume of the sorted cubes accounts for 1 / 4 of the volume of the chamfering machine barrel, and the chamfering machine is turned on 3 min, the blank was prepared;

[0033] (3) Rounding: the rough grinding, medium grinding and fine grinding are carried out in turn to obtain finely ground bead nuclei; the processes adopted for the coarse grinding, medium grinding and fine grinding are respectively as follows:

[0034] ① Coarse grinding: Evenly spread the blanks on the grinding disc of the grind...

Abstract

The invention discloses a method for preparing a nucleus by utilizing lamprotula tortuosa. The method comprises the following steps of: carrying out procedures of chopping, chamfering, rounding, polishing and the like to prepare the circular nucleus by taking the lamprotula tortuosa as a raw material. The nucleus prepared by the method disclosed by the invention has the advantages of white color, strong gloss, circular appearance, small possibility of cracking and the like, and has a wide market prospect and good economic benefits. According to the method disclosed by the invention, the lamprotula tortuosa is developed into a novel material for preparing the nucleus, thus the problems existing in the aspects of a raw material source of the nucleus, the quality of the nucleus and the like can be solved, and the aims of protecting an aquatic organism resource and meeting the requirements of the development of the pearl industry are realized.

Description

technical field [0001] The invention relates to a method for preparing bead cores, in particular to a method for preparing bead cores by using unbalanced clam shells, and belongs to the field of preparing bead cores for seawater pearl cultivation. Background technique [0002] Seawater pearls cultivated in my country, also known as South Pearls, are cultivated from Pinctada martensii by planting nuclei and breeding pearls. They are distributed in some coastal areas of Guangdong, Guangxi and Hainan, and have become a pillar industry of the local marine economy. Nanzhu is famous far and near, and is well-known at home and abroad. In 2000, for the first time, my country surpassed Japan, which had dominated the international pearl market for a long time, and became the world's largest producer of seawater pearls. [0003] The method of cultivating southern pearls is to surgically implant the bead core and the small piece of the mantle into the visceral sac of Pinctada martensii...
