Description

Technical Field

[0001] This utility model relates to the field of pearl processing and screening technology, specifically to a round pearl sieving device for pearl processing. Background Technology

[0002] In the pearl processing industry, pearl selection is a crucial step, directly impacting the quality and market value of the final product. Traditional pearl selection methods rely heavily on manual labor, requiring workers to judge the shape, size, and roundness of pearls by visual inspection and touch. This method is not only inefficient but also susceptible to subjective factors, leading to inaccurate and inconsistent selection results.

[0003] However, existing pearl sorting equipment still has certain limitations in sorting round pearls. Different types and sizes of pearls may require different sorting standards and methods, and existing round pearl sorting devices often lack sufficient flexibility to adapt to diverse pearl sorting needs. Their complex structure also makes maintenance difficult and costly. This increases the company's operating costs and may affect the continued use of the equipment.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a spherical pearl screening device for pearl processing. Utility Model Content

[0005] The purpose of this invention is to provide a spherical pearl screening device for pearl processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A technical solution for a pearl granule screening device includes a base plate with side plates on both sides. A feeding inclined plate is provided above the base plate and is inclined and connected to the side plates. A screening component is provided on the base plate. The screening component includes a guide plate with an inclined design. A screening plate is provided below the guide plate and its two ends are connected to the side plates, which are also inclined. A small aperture area, a medium aperture area, and a large aperture area are arranged sequentially from top to bottom along the inclined direction.

[0008] As a preferred technical solution, the small aperture region is composed of several small aperture sieve holes, the medium aperture region is composed of several medium aperture sieve holes, and the large aperture region is composed of several large aperture sieve holes.

[0009] As a preferred technical solution, vibrators are installed on the inner walls of the two side plates, and a connecting rod is installed between the vibrators.

[0010] As a preferred technical solution, both outer walls of the side plates are equipped with a support and shaking assembly. The support and shaking assembly includes multiple sets of brackets, each set of brackets is equipped with multiple sets of springs, and the top of each set of springs is equipped with a connecting frame, which is connected to the side plate.

[0011] As a preferred technical solution, the surface of the screening plate is coated with a wear-resistant and anti-slip coating to reduce the sliding and wear of pearl particles during the screening process.

[0012] As a preferred technical solution, the tilt angle of the screening plate can be adjusted as needed. At the same time, the screening plate and the side plate are detachably connected to adapt to the screening needs of pearl particles of different sizes and shapes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model is a round pearl sieving device for pearl processing. By designing a sieving plate with multi-level aperture, it can automatically classify and screen pearls according to their roundness and size, reducing reliance on manual operation. This not only improves screening efficiency but also avoids errors caused by human factors, ensuring the accuracy and consistency of screening results.

[0015] The tilt angle of the screening plate is adjustable, and the screening plate and the side plate are detachably connected. This design allows the device to easily adapt to the screening needs of different types and sizes of pearls, improving the flexibility and versatility of the equipment.

[0016] By improving screening efficiency and accuracy, the defect rate was reduced, the overall quality of pearl products was improved, and market competitiveness was enhanced. Furthermore, reduced maintenance costs and flexible adaptability saved the company operating costs and improved economic efficiency.

Detailed Implementation

[0022] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a round pearl sieving device: it includes a base plate 11, and side plates 12 are respectively provided on both sides of the base plate 11. These side plates 12 not only serve as supports, but also as fixing points for the sieving components. A feeding inclined plate 13 is provided obliquely above the base plate 11. The feeding inclined plate 13 is inclined, and one end of it is connected to the side plates 12, which facilitates the pearl particles to slide down from a height onto the sieving components.

[0024] The screening assembly is the core component of the device. It includes a guide plate 21, which is also inclined, with its inclination angle matching that of the feeding inclined plate 13, ensuring that the pearl particles can smoothly slide onto the screening plate 22 below. The screening plate 22 is connected to two side plates 12 at both ends, which are also inclined. Along the inclined direction, from top to bottom, there are three sections: a small aperture area 221, a medium aperture area 222, and a large aperture area 223. Each area consists of sieve holes of the corresponding aperture size, enabling the grading and screening of pearl particles of different sizes.

[0025] To enhance the screening effect, vibrators 32 are installed on the opposing inner walls of the two side plates 12. The vibrators 32 are connected by a connecting rod 31 to generate vibration synchronously. The activation of the vibrators 32 will cause the entire screening assembly to shake, thereby making the pearl particles roll and jump more actively on the screening plate, improving the efficiency and accuracy of screening.

[0026] Furthermore, to further enhance the stability of the device and reduce the impact of vibration on the equipment, vibration support assemblies are installed on the outer walls of both side plates 12. The vibration support assemblies include multiple sets of brackets 41, each set of brackets 41 having multiple sets of springs 42 mounted on it. A connecting frame 43 is mounted on the top of each spring 42, and the connecting frame 43 is connected to the side plate 12. When the vibrator 32 operates, the springs 42 act as buffers and dampers, ensuring the equipment remains stable during vibration.

[0027] To achieve flexibility and versatility, the tilt angle of the screening plate 22 can be adjusted as needed. This adjustment can be achieved by setting adjustable support points or connectors on the side plate 12, allowing the screening plate 22 to adjust its tilt angle within a certain range. Simultaneously, the screening plate 22 and the side plate 12 are detachably connected, such as by bolts or slots, to facilitate the replacement of screening plates of different specifications or types to adapt to the screening needs of pearl particles of different sizes and shapes.

[0028] Finally, to reduce the sliding and wear of pearl particles during the screening process, the surface of the screening plate 22 is coated with a wear-resistant and anti-slip coating. This coating can be made of materials with high wear resistance and low coefficient of friction, such as polytetrafluoroethylene (PTFE) or ceramics. The presence of the coating not only extends the service life of the screening plate but also improves the efficiency and accuracy of screening.

[0029] This solution achieves automated, efficient, and accurate screening of pearl particles through the design of a multi-aperture screening plate, vibrator, and supporting shaking assembly. Furthermore, the flexible and versatile design of the screening plate allows the device to adapt to the screening needs of pearls of different types and sizes, improving the equipment's practicality and economic benefits.
