Description

Technical Field

[0001] This utility model belongs to the field of diamond processing technology, and in particular relates to a screening device for diamond processing. Background Technology

[0002] Diamond, as an important superhard material, is widely used in processing fields such as cutting, grinding, and drilling. Its performance and quality directly affect the processing efficiency and precision of the final product. During the processing of raw diamonds or synthetic diamonds, they undergo multiple steps such as crushing, shaping, screening, and surface treatment according to different application requirements.

[0003] The screening accuracy and residual material removal efficiency in diamond processing directly affect product grading quality, production continuity, and labor costs. Traditional screening equipment often features fixed installations or manually tilting mechanisms. After screening, residual diamond material requires manual tilting of the screening frame. Given the high density of diamonds, even small amounts of residue increase the weight of the screening frame, making manual tilting physically demanding. For large screening equipment, a single person cannot complete the tilting operation; multiple people are required, which is not only labor-intensive but also leads to extremely high labor intensity for operators over extended periods. Therefore, we propose a new screening device for diamond processing. Utility Model Content

[0011] The beneficial effects of this utility model are:

[0012] 1. This diamond processing screening equipment uses a tilting drive component's drive motor to drive the screening component to rotate around a rotating support column via a transmission plate and transmission rod, achieving electric tilting of residual materials. No manual force is required; a single person can operate it by controlling a switch. The motor's driving force is stable and can easily tilt the screening component filled with materials. Compared with the traditional manual method, it reduces labor intensity and avoids physical injury to the operator. Moreover, the arc-shaped slide rail of the tilting guide component cooperates with the sliding block to make the tilting of the screening component smooth and the material tilting trajectory controllable, preventing spillage.

[0013] 2. This diamond processing screening equipment achieves efficient screening through the vibration motor of the screening component. After screening, there is no need to disassemble the fixed parts. The tilting drive component can be started directly to tilt the equipment. The screening component and the main frame are rotatably connected by a rotating support column. The equipment can tilt the equipment on the spot without the need for handling. From the completion of screening to the collection of residual materials, the screening and tilting are integrated, simplifying the operation process and significantly improving the continuity of production.

[0020] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0021] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0022] Example 1: This example provides a screening device for diamond processing, including a main frame 1. A rotating support column 3 is fixedly connected to the inner wall of the main frame 1. A U-shaped frame 4 is rotatably connected to the outer surface of the rotating support column 3. A screening component 6 is installed inside the U-shaped frame 4. A tilting drive component 7 for driving the screening component 6 to rotate is installed on one side of the main frame 1. A tilting guide component 8 connected to the screening component 6 is installed on one side of the screening component 6. The tilting drive component 7 includes a mounting base 71 fixedly connected to the main frame 1, a drive motor 72 fixedly connected to the mounting base 71, and a transmission connecting plate 73 fixedly connected to the output end of the drive motor 72. Two transmission connecting rods 74 are fixedly connected to the outer surface of the transmission connecting plate 73. The outer surface of each transmission connecting rod 74 is connected to the screening component 6.

[0023] The main frame 1 and the rotating support column 3 provide rotational support for the screening component 6. The motor drive structure of the tilting drive component 7 enables electric tilting, which is labor-saving and convenient. The tilting guide component 8 ensures stable tilting, solving the problems of laborious tilting and cumbersome collection in traditional equipment. It balances screening efficiency and collection convenience. After adopting this screening equipment, a single person can start the tilting drive component 7 through the PLC controller to quickly complete the tilting of the screening component 6. The residual material is completely poured out without spillage. The tilting process does not require manual force, which greatly reduces the labor intensity of the operator.

[0024] Example 2: This example provides a screening device for diamond processing. In addition to the technical solutions of the above examples, it also has the following technical features: the screening component 6 includes two side frames 61 fixedly connected to the U-shaped frame 4. A set of guide rods 62 are fixedly connected to the inner wall of each side frame 61. Sliding seats 63 are slidably connected to the outer surfaces of the two guide rods 62. A vibration motor 65 is fixedly connected to the bottom surface of one of the sliding seats 63. A first screen 66 is fixedly connected to the adjacent side of the two sliding seats 63. A second screen 67 is fixedly connected to the bottom surface of the first screen 66.

[0025] Among them, the side frame 61 of the screening component 6 provides a stable mounting base for the guide rod 62 and the buffer spring 64; the vibration motor 65 drives the sliding seat 63 to slide along the guide rod 62, which drives the first screen 66 and the second screen 67 to vibrate, so as to achieve precise classification of diamond particle size and improve screening accuracy with double screens.

[0026] Example 3: This example provides a screening device for diamond processing. In addition to the technical solutions of the above examples, it also has the following technical features: the screening component 6 further includes a plurality of buffer springs 64 fixedly connected in the side frame 61. The end of each buffer spring 64 away from the side frame 61 is fixedly connected to the outer surface of the sliding seat 63. The bottom surface of the second screen 67 is fixedly connected to the feed cylinder 68. The upper surfaces of the two side frames 61 are fixedly connected to the feeding hopper 9.

[0027] Among them, multiple buffer springs 64 of the screening component 6 connect the side frame 61 and the sliding seat 63 to form an elastic vibration structure, which makes the vibration frequency of the screen more stable and improves the screening uniformity. The buffer springs 64 absorb the impact force generated by the vibration motor 65 and prevent the vibration from being transmitted to the main frame 1, causing the entire equipment to shake. The feeding cylinder 68 is fixedly connected to the second screen 67 to ensure that qualified materials after screening fall directly through the feeding cylinder 68.

[0028] Example 4: This example provides a screening device for diamond processing. In addition to the technical solutions of the above examples, it also has the following technical features: two limiting horizontal plates 5 are fixedly connected to the inner wall of the main frame 1, the U-shaped frame 4 is located between the two limiting horizontal plates 5, and the two limiting horizontal plates 5 are respectively located below the two side frames 61.

[0029] Among them, the two limiting horizontal plates 5 on the inner wall of the main frame 1 restrict the herringbone frame 4 to the middle position, ensuring that the screening component 6 is in a horizontal state during screening, avoiding tilting that would cause uneven screening. The limiting horizontal plates 5 provide bottom support for the herringbone frame 4, enhancing the load-bearing capacity of the screening component 6, and can be adapted to screening larger batches of diamonds.

[0030] Example 5: This example provides a screening device for diamond processing. In addition to the technical solutions of the above examples, it also has the following technical features: multiple reinforcing ribs 2 are fixedly connected to the inner wall of the main frame 1.

[0031] Among them, the multiple reinforcing ribs 2 on the inner wall of the main frame 1 enhance the overall structural strength of the frame, preventing deformation and cracking of the frame when the screening component 6 vibrates or tilts. The reinforcing ribs 2 disperse the stress borne by the frame, and can effectively resist gravity and impact when the screening component 6 is full of material and tilted, ensuring the safe operation of the equipment.

[0032] Example 6: This example provides a screening device for diamond processing. In addition to the technical solutions of the above examples, it also has the following technical features: the tilting guide component 8 includes a support frame 81 fixedly connected to the main frame 1 and an arc-shaped slide rail 82 fixedly connected to the support frame 81. A sliding block 83 is slidably connected inside the arc-shaped slide rail 82, and the outer surface of the sliding block 83 is connected to the screening component 6.

[0033] Among them, the support frame 81 of the tilting guide component 8 provides a stable installation base for the arc-shaped slide rail 82, ensuring that the position of the slide rail is fixed. The arc-shaped slide rail 82 cooperates with the sliding block 83 to provide precise guidance for the tilting and flipping of the screening component 6, so that the flipping trajectory runs smoothly in an arc shape and avoids shaking that causes material to spill.

[0034] Working principle:

[0035] According to the screening and grading requirements, corresponding collection containers are placed below the first screen 66 and the second screen 67 and in the tilting direction. Ensure that the collection containers are placed stably. The feeding cylinder 68 is aligned with the inlet of the lower collection container, and the collection container in the tilting direction is aligned with the outlet of the screening component 6. Then, the diamond raw material to be screened is slowly poured into the screening component 6 through the feeding hopper 9. During the feeding process, the feeding is kept uniform to avoid pouring too much at once and causing the screen to clog. Ensure that the raw material is evenly distributed on the first screen 66.

[0036] Then, the vibration motor 65 is started. The vibration motor 65 drives the sliding seat 63 to slide back and forth along the guide rod 62 of the side frame 61, causing the first screen 66 and the second screen 67 to vibrate. Coarse diamond particles are intercepted by the first screen 66, medium and fine diamond particles fall through the first screen 66 to the second screen 67, and fine diamond particles fall through the second screen 67 and into the collection container below through the feed cylinder 68. The buffer spring 64 absorbs the vibration impact to ensure stable screening. After screening is completed, the vibration motor 65 is turned off.

[0037] When dumping residual material, the drive motor 72 of the dumping drive assembly 7 can be activated. The drive motor 72 drives the transmission connecting plate 73 to rotate, and through the transmission connecting rod 74, it pulls the screening assembly 6 and the U-shaped frame 4 to rotate around the rotating support column 3. At the same time, the sliding block 83 of the dumping guide assembly 8 slides along the arc-shaped slide rail 82 to provide guidance for the screening assembly 6. When the screening assembly 6 is rotated to the set angle, the screened residual material on the first screen 66 and the second screen 67 is poured out and falls into the corresponding collection container. The drive motor 72 is controlled to rotate in the opposite direction, driving the screening assembly 6 to reset to the limit horizontal plate 5 and restore the horizontal state.
