Abstract

This utility model discloses a diamond micropowder sorting screen structure for superhard materials, relating to the field of screening technology. It includes a frame and a feed box. A screening mechanism is movably connected inside the frame, and is inclinedly arranged on the inner side of the frame. Reciprocating vibration mechanisms are movably connected to both sides of the screening mechanism.

[0001] This utility model relates to the field of screening technology, and in particular to a diamond micro powder sorting sieve structure for superhard materials. Background Technology

[0002] Diamond micron powder, as a superhard material, is widely used in semiconductor wafer polishing, precision optical component grinding, and cemented carbide tool machining. Its particle size distribution (e.g., D50 = 1-50 μm) and purity directly determine the processing accuracy and quality of downstream products.

[0003] However, diamond micro powder particles are small, and the corresponding sieve apertures are also smaller. Traditional sieves are prone to particle clogging or accumulation during the screening of diamond micro powder, which affects the sorting quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a diamond micro powder sorting sieve structure for superhard materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a diamond micro powder sorting screen structure for superhard materials, comprising a frame and a feeding box, wherein a sorting mechanism is movably connected inside the frame, the sorting mechanism is inclinedly arranged on the inner side of the frame, and a reciprocating vibration mechanism is movably connected on both sides of the sorting mechanism. The sorting mechanism includes a screen frame, a screen, a support frame and a collecting plate. The screen is fixedly connected to the lower side of the screen frame, the screen frame is fixedly connected to the upper side of the support frame, and the collecting plate is fixedly connected to the lower side of the support frame. The reciprocating vibration mechanism includes an eccentric disk, a swing arm, an auxiliary arm and a power component. The auxiliary arm is rotatably connected to the end of the support frame, the swing arm is rotatably connected to the middle of the side of the support frame, the lower end of the swing arm is rotatably connected to the eccentric part of the eccentric disk, and the power component drives the eccentric disk to rotate.

[0006] Preferably, the other end of the auxiliary arm is rotatably connected to the inside of the frame, and the screen frame is located below the feed box.

[0007] Preferably, the power assembly includes a stepper motor, a drive pulley, an extension shaft, a belt, a driven pulley, and a central shaft, with the central shaft fixedly connected to the center of the eccentric disc.

[0008] Preferably, the central shaft is rotatably mounted inside the frame, and the driven pulley is fixedly mounted in the middle of the central shaft.

[0009] Preferably, the belt drive is connected to the outside of the driven pulley, and the driving pulley is connected to the other end of the belt.

[0010] Preferably, the drive pulley is fixedly installed at the end of the extension shaft, and the drive pulley is fixedly connected to the output shaft of the stepper motor through a coupling.

[0011] Preferably, the other end of the extension shaft is rotatably connected to the inside of the frame, and the stepper motor is fixedly connected to the inside of the frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the eccentric disc receives power from the power component and rotates. The shaft at its eccentric point drives the lower end of the swing arm to make a circular motion, while the upper end of the swing arm is rotatably connected to the middle of the side of the support frame. Thus, the upper end of the swing arm also makes a circular motion. Under the connection of the four sets of auxiliary arms, the swing arm drives the support frame to maintain an inclined posture and make a circular motion inside the frame. The diamond powder in the feed box falls directly onto the screen from the lower outlet. The inclined screen facilitates the falling of the diamond powder, accelerates the screening rate, and the screen is in reciprocating motion with a component force of up and down movement. Therefore, it drives the diamond powder to jump up and down, avoiding it from getting stuck in the screen holes and improving the screening efficiency.

[0014] 2. In this utility model, by starting the stepper motor, the stepper motor drives the extension shaft to rotate. The other end of the extension shaft is restricted to rotate inside the frame to ensure stable rotation of the extension shaft, thereby driving the drive pulley to rotate. After belt transmission, the drive pulley drives the driven pulley to rotate. The driven pulley drives the central shaft in the middle to rotate. Both ends of the central shaft are also restricted to rotate inside the frame to ensure that the central shaft does not easily become displaced. This drives the eccentric disks installed at both ends to rotate. The shaft at the eccentric part of the eccentric disk drives the lower end of the swing arm to make a circular motion, while the upper end of the swing arm is rotatably connected to the middle of the side of the load-bearing frame. Thus, the upper end of the swing arm also makes a circular motion. Under the connection of the four sets of auxiliary arms, the swing arm drives the load-bearing frame to maintain an inclined posture and make a circular motion inside the frame.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a diamond micro powder sorting screen structure for superhard materials, including a frame 1 and a feed box 2. A sieving mechanism 3 is movably connected inside the frame 1. The sieving mechanism 3 is inclinedly arranged inside the frame 1. A reciprocating vibration mechanism 4 is movably connected to both sides of the sieving mechanism 3. The sieving mechanism 3 includes a screen frame 31, a screen 32, a support frame 33, and a collection plate 34. The screen 32 is fixedly connected to the lower side of the screen frame 31, the screen frame 31 is fixedly connected to the upper side of the support frame 33, and the collection plate 34 is fixedly connected to the lower side of the support frame 33. The reciprocating vibration mechanism 4 includes an eccentric disk 47, a swing arm 48, an auxiliary arm 49, and a power component. The auxiliary arm 49 is rotatably connected to the end of the support frame 33, the swing arm 48 is rotatably connected to the middle of the side of the support frame 33, and the lower end of the swing arm 48 is rotatably connected to the eccentric part of the eccentric disk 47. The power component drives the eccentric disk 47 to rotate.

[0023] The specific setup and function of this embodiment are described below: The diamond powder to be screened is introduced into the feed box 2. The eccentric disk 47 receives power from the power unit and rotates. The shaft at its eccentric point drives the lower end of the swing arm 48 to perform a circular motion. The upper end of the swing arm 48 is rotatably connected to the middle of the side of the support frame 33, thus the upper end of the swing arm 48 also performs a circular motion. Under the connection of the four sets of auxiliary arms 49, the swing arm 48 drives the support frame 33 to maintain an inclined posture and perform a circular motion inside the frame 1. The diamond powder in the feed box 2 falls directly onto the screen 32 from the lower outlet. The inclined screen 32 facilitates the processing of diamond powder. As the powder falls, the screening rate is accelerated, and the screen 32 is in reciprocating motion with an up-and-down force component, which causes the diamond powder to jump up and down, preventing it from getting stuck in the screen holes of the screen 32 and improving the screening efficiency. The screen 32 is made of DLC-coated titanium alloy, which has ultra-high hardness and wear resistance, low friction and high throughput and corrosion resistance, significantly improving screening efficiency and service life. The screen screening mechanism 3 has a certain length to ensure efficient screening of batches of diamond powder. Diamond powder that meets the requirements falls into the collection plate 34, while diamond powder that does not meet the requirements is temporarily left on the screen 32 and collected and processed separately from the end outlet.

[0024] Example 2: Figure 1 - Figure 4 As shown, the other end of the auxiliary arm 49 is rotatably connected to the inner side of the frame 1. The screen frame 31 is located below the feed box 2. The power assembly includes a stepper motor 41, a drive pulley 42, an extension shaft 43, a belt 44, a driven pulley 45, and a central shaft 46. The central shaft 46 is fixedly connected to the middle of the eccentric disk 47 and is rotatably installed inside the frame 1. The driven pulley 45 is fixedly installed in the middle of the central shaft 46. The belt 44 is drivenly connected to the outer side of the driven pulley 45. The drive pulley 42 is drivenly connected to the other end of the belt 44. The drive pulley 42 is fixedly installed at the end of the extension shaft 43 and is fixedly connected to the output shaft of the stepper motor 41 through a coupling. The other end of the extension shaft 43 is rotatably connected to the inside of the frame 1, and the stepper motor 41 is fixedly connected to the inside of the frame 1.

[0025] The overall effect of this embodiment is as follows: by starting the stepper motor 41, the stepper motor 41 drives the extension shaft 43 to rotate. The other end of the extension shaft 43 is restricted to rotate inside the frame 1, ensuring that the extension shaft 43 rotates stably. This drives the drive pulley 42 to rotate, which in turn drives the driven pulley 45 to rotate after being driven by the belt 44. The driven pulley 45 drives the central shaft 46 in the middle to rotate. Both ends of the central shaft 46 are also restricted to rotate inside the frame 1, ensuring that the central shaft 46 does not easily become displaced. This drives the eccentric disks 47 installed at both ends to rotate. The shaft at the eccentric part of the eccentric disk 47 drives the lower end of the swing arm 48 to make a circular motion. The upper end of the swing arm 48 is rotatably connected to the middle of the side of the support frame 33. Thus, the upper end of the swing arm 48 also makes a circular motion. Under the connection of the four sets of auxiliary arms 49, the swing arm 48 drives the support frame 33 to maintain an inclined posture and make a circular motion inside the frame 1.

[0026] The operating method and working principle of this device are as follows: The diamond powder to be screened is introduced into the feed box 2. The stepper motor 41 drives the extension shaft 43 to rotate. The other end of the extension shaft 43 is restricted to rotate within the frame 1, ensuring stable rotation of the extension shaft 43. This drives the drive pulley 42 to rotate, which, after being driven by the belt 44, drives the driven pulley 45 to rotate. The driven pulley 45 drives the central shaft 46 in the middle to rotate. Both ends of the central shaft 46 are also restricted to rotate within the frame 1, ensuring that the central shaft 46 does not easily shift. This drives the eccentric discs 47 installed at both ends to rotate. The shaft at the eccentric point of the eccentric disc 47 drives the lower end of the swing arm 48 to perform a circular motion, while the upper end of the swing arm 48 is rotatably connected to the middle of the side of the bearing frame 33. Thus, the swing arm 48... The end also makes a circular motion. Under the connection of the four sets of auxiliary arms 49, the swing arm 48 drives the bearing frame 33 to maintain an inclined posture and make a circular motion inside the frame 1. The diamond powder in the feed box 2 falls directly onto the screen 32 from the lower outlet. The inclined screen 32 facilitates the falling of diamond powder and accelerates the screening rate. The screen 32 is in reciprocating motion and has a component force of up and down motion, which causes the diamond powder to jump up and down, avoiding it from getting stuck in the screen holes of the screen 32 and improving the screening efficiency. The screening mechanism 3 has a certain length to ensure efficient screening of batch diamond powder. The diamond powder that meets the requirements falls into the collection plate 34, while the diamond powder that does not meet the requirements stays on the screen 32 and is collected and processed separately from the end outlet.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
