Description

Technical Field

[0001] This utility model relates to the field of material screening equipment technology, and in particular to a nitriding material screening machine with easy screen replacement. Background Technology

[0002] Nitride materials are a class of compound materials formed by combining nitrogen with metallic or non-metallic elements. They are widely used in high-end industrial fields such as ceramics manufacturing, electronic packaging, semiconductors, and refractory materials. In the production and application of nitride materials, their particle size distribution has a significant impact on product performance. For example, when ultrafine aluminum nitride powder is used in electronic packaging, particle size uniformity directly affects heat dissipation efficiency. Therefore, nitride materials need to be sieved using sieving equipment to meet the requirements of different application scenarios.

[0003] However, in existing screening machines for nitriding materials, the screens are mostly connected to the equipment using bolt assemblies. This installation structure has significant drawbacks in actual operation: when replacing the screen, tools are needed to remove each bolt individually, which is cumbersome and time-consuming. Especially for scenarios that require frequent replacement of screens with different mesh sizes to meet different particle size classification needs, it will seriously affect production efficiency. To improve this, a nitriding material screening machine with convenient screen replacement is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nitriding material screening machine with a convenient screen replacement mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A nitriding material screening machine with easy screen replacement includes a support frame. A movable frame is mounted on the support frame via a support mechanism. A screen body is mounted on the movable frame. A hidden groove is provided on the movable frame. A positioning frame is slidably inserted through the hidden groove via a first elastic mechanism. A positioning groove is provided on the screen body. A movable groove is provided on the movable frame. A movable plate is mounted within the movable groove via a second elastic mechanism. The movable plate is connected to the support frame via a limiting mechanism. An equipment plate and an extension plate are respectively mounted on the support frame and the movable frame. A servo motor is mounted on the equipment plate. The servo motor is connected to the extension plate via a connecting mechanism.

[0007] Preferably, the support mechanism includes a support plate fixedly mounted on the movable frame, a support wheel installed at the bottom of the support plate, and a support groove corresponding to the support wheel on the support frame.

[0008] Preferably, the first elastic mechanism includes a first spring disposed in the hidden groove, with both ends of the first spring connected to the inner wall of the hidden groove and the outer wall of the positioning frame, respectively.

[0009] Preferably, the second elastic mechanism includes a second spring disposed in the movable groove, with both ends of the second spring connected to the inner wall of the movable groove and the outer wall of the movable plate, respectively.

[0010] Preferably, the limiting mechanism includes a limiting wheel rotatably mounted on the movable plate, and the outer wall of the support frame is provided with a limiting groove corresponding to the limiting wheel.

[0011] Preferably, the connecting mechanism includes a turntable fixedly mounted on the output shaft of the servo motor, and fixed rods are fixedly mounted on both the turntable and the extension plate. A connecting plate is provided on both fixed rods, and a fixed cover is threaded onto both fixed rods.

[0012] The beneficial effects of this utility model are:

[0013] 1. With the help of the positioning frame, the first spring and the positioning groove, the screen and the movable frame can be quickly separated by dragging the positioning frame without removing the bolts, which greatly shortens the replacement time and is suitable for the frequent screen replacement needs in the screening of nitriding materials.

[0014] 2. The support wheels and support grooves ensure the smooth movement of the movable frame; the first spring securely engages the positioning frame with the positioning groove to prevent the screen from falling off; the limit wheels and limit grooves work together to prevent vertical displacement of the movable frame, thus enhancing the overall stability of the equipment operation.

[0015] 3. The fixed cover can be detached to separate the connecting plate from the fixed rod. Combined with the operation of the movable plate, the movable frame and support frame can be quickly disassembled, which is convenient for the maintenance of internal components; the screen is easy to disassemble and replace.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A nitriding material screening machine with convenient screen replacement includes a support frame 1. A movable frame 2 is provided on the support frame 1 via a support mechanism. A screen body 3 is provided on the movable frame 2. A hidden groove 19 is provided on the movable frame 2. A positioning frame 20 is slidably inserted through the hidden groove 19 via a first elastic mechanism. A positioning groove 21 is provided on the screen body 3. A movable groove 23 is provided on the movable frame 2. A movable plate 12 is provided in the movable groove 23 via a second elastic mechanism. The movable plate 12 is connected to the support frame 1 via a limiting mechanism. An equipment plate 7 and an extension plate 10 are respectively provided on the support frame 1 and the movable frame 2. A servo motor 8 is provided on the equipment plate 7. The servo motor 8 is connected to the extension plate 10 via a connecting mechanism.

[0025] The support mechanism includes a support plate 4 fixedly mounted on the movable frame 2, with support wheels 5 installed at the bottom of the support plate 4, and support grooves 6 on the support frame 1 corresponding to the support wheels 5. The support wheels 5 enable the stable movable installation of the movable frame 2 relative to the support frame 1.

[0026] The first elastic mechanism includes a first spring 22 disposed within the concealed groove 19, with both ends of the first spring 22 connected to the inner wall of the concealed groove 19 and the outer wall of the positioning frame 20, respectively. The first spring 22 enables the positioning frame 20 to be dragged, ensuring that its rod is within the positioning groove 21, at which point the screen body 3 cannot detach from the movable frame 2.

[0027] The second elastic mechanism includes a second spring 15 disposed within the movable groove 23, with both ends of the second spring 15 connected to the inner wall of the movable groove 23 and the outer wall of the movable plate 12, respectively. The second spring 15 enables the movable plate 12 to be dragged, thereby ensuring that the limiting wheel 13 is within the limiting groove 14.

[0028] The limiting mechanism includes a limiting wheel 13 rotatably mounted on the movable plate 12, and a limiting groove 14 corresponding to the limiting wheel 13 is provided on the outer wall of the support frame 1. When the limiting wheel 13 is partially within the limiting groove 14, it can effectively prevent the movable frame 2 from rising vertically relative to the support frame 1.

[0029] The connecting mechanism includes a turntable 9 fixedly mounted on the output shaft of the servo motor 8. Both the turntable 9 and the extension plate 10 are fixedly equipped with fixing rods 16. A connecting plate 11 is shared by the two fixing rods 16, and a fixing cover 17 is threaded onto each of the two fixing rods 16. As shown in the figure, the connecting plate 11 also has through holes 18 corresponding to the fixing rods 16. The fixing rods 16 on the turntable 9 are eccentrically designed. This design allows the movable frame 2 and other components to move horizontally back and forth after the servo motor 8 is started, relying on the aforementioned components.

[0030] By setting a threaded fixed cover 17, the connecting plate 11 can be vertically raised after the fixed cover 17 is removed, thereby detaching from the two fixed rods 16 and facilitating the disassembly and separation of subsequent devices.

[0031] When this utility model is in use, after the servo motor 8 is started, it works with the turntable 9 and connecting plate 11 to drive the movable frame 2 and other components to move back and forth horizontally relative to the support frame 1, so that the nitrided material on the screen body 3 can be screened.

[0032] In this solution, the threaded fixed cover 17 can be rotatably unscrewed, and then the connecting plate 11 can be vertically raised to disengage from the two fixed rods 16. Then, the movable plate 12 is dragged to make the limiting wheel 13 disengage from the limiting groove 14, and then the movable frame 2 and other components can be vertically raised to disengage from the support frame 1, thereby completing the disassembly of the above components.

[0033] In this solution, the positioning frame 20 located in the hidden groove 19 can be dragged, and then the rod of the positioning frame 20 will disengage from the positioning groove 21, thereby completing the fixed installation of the screen body 3 relative to the movable frame 2. The screen body 3 can be disassembled by vertically descending, thus facilitating its replacement.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
