[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-4 This is an embodiment of the present invention, which provides a pearl processing screening device, comprising: The system comprises: a fixed frame 101; a limiting plate 102 fixedly installed on the side wall of the fixed frame 101; a collection frame 103 fixedly connected to the center of the fixed frame 101; a fixing plate 104 fixedly installed on the side surface of the limiting plate 102 by bolts; a connecting frame 105 fixedly installed on the inner wall of the fixing plate 104; a mounting plate 106 fixedly connected to the side wall of the connecting frame 105; a vibration motor 107 adapted to be installed on the surface of the mounting plate 106; a cable 108 electrically connected to the connection point of the vibration motor 107; a screening box 109 fixedly connected to the side surface of the connecting frame 105; a feeding assembly 110 fixedly installed at the end of the screening box 109; a screen plate 111 snapped into the inner cavity of the screening box 109; a snapping assembly 112 fixedly connected to the inner wall of the screening box 109; and a sliding plate 113 fixedly installed at the end of the screening box 109.

[0019] The screening box 109 includes a box body 109a, a first corner piece 109b fixedly installed on the side surface of the box body 109a, a vibration spring 109c fixedly connected to the side wall of the first corner piece 109b, and a second corner piece 109d fixedly connected to the bottom of the vibration spring 109c.

[0020] Vibration springs 109c are provided around the box 109a, and the vibration motor 107 works in conjunction with the vibration springs 109c.

[0021] Specifically, when the device is working, the operator puts the pearls to be screened into the feeding frame 110b through the feeding port 110c, and the pearls fall onto the screen plate 111 inside the screening box 109; the vibration motor 107 is started, which, in cooperation with the vibration springs 109c distributed around the box 109a, drives the entire screening box 109 to produce stable and uniform vibration; under the action of vibration, the pearls continuously roll and move on the surface of the screen plate 111, and the pearl particles smaller than the aperture of the through holes of the screen plate 111 pass through the through holes and fall into the collection frame 103 below, realizing graded screening; while the pearls that fail to be screened continue to move along the screen plate 111 and are finally discharged through the sliding plate 113.

[0022] The feeding assembly 110 includes a fixed corner piece 110a fixedly installed at the end of the housing 109a, a feeding frame 110b fixedly installed on the side wall of the fixed corner piece 110a by bolts, and a feeding port 110c opened on the side surface of the feeding frame 110b.

[0023] The sieve plate 111 includes a plate body 111a and a fixing post 111b fixedly connected to the bottom of the plate body 111a. The surface of the plate body 111a has several through holes.

[0024] The snap-fit ​​assembly 112 includes a connecting block 112a fixedly connected to the side wall of the housing 109a, a plug groove 112b formed on the side surface of the connecting block 112a, and a limiting block 112c used in conjunction with the plug groove 112b.

[0025] The snap-fit ​​assembly 112 also includes a fixed cylinder 112d that contacts and cooperates with the limiting block 112c, an elastic rod 112e inserted into the side wall of the fixed cylinder 112d, and a clamping block 112f fixedly connected to the end of the elastic rod 112e.

[0026] It should be noted that pearls are fed into the feeding frame 110b through the feeding port 110c, and the pearls fall onto the surface of the sieve plate 111. The sieve plate 111 is inserted into the insertion slot 112b of the connecting block 112a through the fixing post 111b at its bottom, and is initially limited by the limiting block 112c. At the same time, the elastic rod 112e pushes the clamping block 112f to tightly press against the limiting block 112c, thereby quickly and firmly clamping the sieve plate 111 into the box 109a. After the vibration is started, the pearls vibrate and are screened on the surface of the sieve plate 111. Pearls that meet the specifications fall into the collection frame 103 through the through hole, completing the grading and screening.

[0027] In use, pearls are fed into the sieve plate 111 through the feeding port 110c. After the vibration motor 107 is started, the motor and the vibration springs 109c around the housing 109a work together to generate uniform vibration, driving the pearls to roll and move on the surface of the sieve plate 111. Pearls smaller than the sieve hole size pass through the through hole and fall into the collection frame 103 below for collection, while pearls that do not meet the size are discharged along the sieve plate 111 via the sliding plate 113. The sieve plate 111 is inserted into the insertion slot 112b of the connecting block 112a through the bottom fixing column 111b, and is initially positioned by the limiting block 112c. Then, the elastic rod 112e pushes the clamping block 112f to press against the limiting block 112c to complete the quick fixation, thereby ensuring a stable and efficient screening process.

[0028] In summary, the combined use of the vibrating motor 107 and the evenly distributed vibrating springs 109c enables the screening box 109 to generate efficient and stable vibration, improving the screening efficiency and accuracy of pearls. Its unique snap-fit ​​assembly 112 achieves rapid positioning of the screen plate 111 through the cooperation of the fixed column 111b and the insertion slot 112b, and uses the clamping block 112f driven by the elastic rod 112e to achieve self-locking fastening, making the screen replacement operation simple and quick. This effectively solves the technical problems of cumbersome screen replacement and unstable vibration in traditional devices, while reducing the breakage rate of pearls during the screening process.
