Description

Technical Field

[0001] This utility model relates to the field of powder screening equipment technology, and in particular to a metal powder screening equipment. Background Technology

[0002] Metal powder refers to a group of metal particles smaller than 1 mm in size, including single metal powder, alloy powder, and powders of certain refractory compounds with metallic properties. It is the main raw material for powder metallurgy. Metallic elements are generally silvery-white, but when metals are under certain conditions, they become black powders. Most metal powders are black. In the production and processing of metal powder, since metal powder contains particles of different sizes, it is necessary to screen the metal powder in order to meet the requirements of use. Screening equipment is required for the screening process.

[0003] Existing screening equipment typically involves pouring metal powder into the equipment and then letting non-compliant metal powder fall off naturally through a filter screen. This simple screening method results in poor overall screening efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing screening equipment typically pours metal powder into the equipment during screening, and then allows non-compliant metal powder to fall off naturally through a filter screen. This simple screening method results in poor overall screening efficiency. Therefore, this invention proposes a metal powder screening device.

[0005] To achieve the above objectives, the present invention employs the following technology: a metal powder screening device, comprising a shell, a discharge shell at the bottom of the shell, and a locking mechanism on both sides of the shell;

[0006] The screening mechanism includes a screening cylinder disposed inside the outer shell. A branch plate is provided on one side of the inner wall of the screening cylinder. A feed pipe is fixedly connected to the middle of the branch plate. The feed pipe is slidably connected to the outer shell through a groove. A first bevel gear is fixedly connected to the surface of the feed pipe and a first folding plate is rotatably connected to it. The first bevel gear is connected to a striking mechanism through a connecting mechanism. A buffer mechanism is fixedly connected to the middle of the surface of the screening cylinder.

[0007] As a further description of the above technical solution: the connecting mechanism includes a connecting rod rotatably connected to the bottom of the first folding plate, a second bevel gear meshing with the first bevel gear is fixedly connected to the top of the connecting rod, and a connecting cylinder is slidably connected to the surface of the connecting rod.

[0008] As a further description of the above technical solution: the buffer mechanism includes a sleeve plate installed in the middle of the surface of the screening cylinder, a sliding sleeve rotatably connected to the surface of the sleeve plate, a hanging rod fixedly connected to the top of the sliding sleeve, the top of the hanging rod passing through the top of the outer shell and connected to a baffle, and a spring sleeved on the surface of the hanging rod.

[0009] As a further description of the above technical solution: the striking mechanism includes a second folding plate installed at the bottom of the back of the housing and rotatably connected to the connecting cylinder. A drive motor is fixedly connected to one side of the second folding plate. A drive rod is connected to the output end of the drive motor. A third bevel gear is fixedly connected to one side of the surface of the drive rod. A fourth bevel gear meshes with the tooth surface of the third bevel gear. The top of the fourth bevel gear is connected to the connecting cylinder. The other end of the drive rod extends into the housing and a cam is provided on the surface of the drive rod.

[0010] As a further description of the above technical solution: the locking mechanism includes mounting seats installed on both sides of the housing, and a threaded rod is threaded through one side of each of the two mounting seats. One end of the threaded rod is rotatably connected to a C-shaped clamp, and a locking rod is fixedly connected to one side of the inner wall of the C-shaped clamp.

[0011] As a further description of the above technical solution: the other end of the two locking rods is provided with a sealing plate, and one side of the sealing plate is fitted with the opening on the front of the housing.

[0012] As a further description of the above technical solution: support plates are fixedly connected to both sides of the bottom of the outer shell.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] With the connection mechanism, screening mechanism, and striking mechanism in place, the drive motor drives the drive rod to rotate during operation. The rotation of the drive rod drives the third bevel gear to rotate, which in turn drives the fourth bevel gear to rotate. The fourth bevel gear then drives the first bevel gear to rotate via the connection mechanism. The rotation of the first bevel gear drives the feed pipe and the screening cylinder to rotate, thereby turning and screening the metal powder inside the screening cylinder. At the same time, the rotation of the drive rod drives the cam to rotate, which in turn strikes the bottom of the screening cylinder, causing the metal powder inside the screening cylinder to vibrate and thus improving the overall screening effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 The metal powder screening device provided in this embodiment includes a shell 1, a discharge shell 7 is provided at the bottom of the shell 1, and a locking mechanism 8 is provided on both sides of the shell 1.

[0024] The screening mechanism 3 includes a screening cylinder 301 disposed inside the outer casing 1. A branch plate 302 is provided on one side of the inner wall of the screening cylinder 301. A feed pipe 303 is fixedly connected to the middle of the branch plate 302. The feed pipe 303 is slidably connected to the outer casing 1 through a sliding groove. A first bevel gear 304 is fixedly connected to the surface of the feed pipe 303 and a first folding plate 305 is rotatably connected to it. The first bevel gear 304 is connected to a striking mechanism 4 through a connecting mechanism 2. A buffer mechanism 6 is fixedly connected to the middle of the surface of the screening cylinder 301.

[0025] The connecting mechanism 2 drives the first bevel gear 304 to rotate, and the rotation of the first bevel gear 304 drives the feed pipe 303 and the screening cylinder 301 to rotate. The screening cylinder 301 has a mesh size of 200 mesh, which in turn flips and screens the metal powder inside the screening cylinder 301.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the connecting mechanism 2 includes a connecting rod 201 rotatably connected to the bottom of the first folding plate 305, a second bevel gear 202 that meshes with the first bevel gear 304 is fixedly connected to the top of the connecting rod 201, and a connecting cylinder 203 is slidably connected to the surface of the connecting rod 201.

[0027] Among them, the rotation of the fourth bevel gear 405 drives the connecting cylinder 203 to rotate, the rotation of the connecting cylinder 203 drives the connecting rod 201 to rotate, the rotation of the connecting rod 201 drives the second bevel gear 202 to rotate, and the second bevel gear 202 drives the first bevel gear 304 to rotate.

[0028] Specifically, such as Figure 3 and Figure 5 As shown, the buffer mechanism 6 includes a sleeve plate 601 installed in the middle of the surface of the screening cylinder 301. A sliding sleeve 602 is rotatably connected to the surface of the sleeve plate 601. A hanging rod 603 is fixedly connected to the top of the sliding sleeve 602. The top of the hanging rod 603 passes through the top of the outer shell 1 and is connected to a baffle. A spring 604 is sleeved on the surface of the hanging rod 603.

[0029] When the cam 406 strikes the screening cylinder 301, it will push the screening cylinder 301 to rise. The screening cylinder 301 will drive the feed pipe 303 and the first bevel gear 304 and the first baffle plate 305 connected to the surface of the feed pipe 303 to move upward. The upward movement of the screening cylinder 301 will compress the spring 604 to buffer and protect the upward movement of the screening cylinder 301.

[0030] Specifically, such as Figure 4 As shown, the striking mechanism 4 includes a second folding plate 401 installed at the bottom of the back of the housing 1 and rotatably connected to the connecting cylinder 203. A drive motor 402 is fixedly connected to one side of the second folding plate 401. A drive rod 403 is connected to the output end of the drive motor 402. A third bevel gear 404 is fixedly connected to one side of the surface of the drive rod 403. A fourth bevel gear 405 meshes with the tooth surface of the third bevel gear 404. The top of the fourth bevel gear 405 is connected to the connecting cylinder 203. The other end of the drive rod 403 extends into the interior of the housing 1 and a cam 406 is provided on the surface of the drive rod 403.

[0031] When the drive rod 403 rotates, it drives the cam 406 to rotate. The rotation of the cam 406 knocks on the bottom of the screening cylinder 301, thereby knocking and vibrating the metal powder inside the screening cylinder 301, thus improving the overall screening effect.

[0032] Specifically, such as Figure 2As shown, the locking mechanism 8 includes mounting seats 801 installed on both sides of the housing 1. A threaded rod 802 is threaded through one side of each mounting seat 801. One end of the threaded rod 802 is rotatably connected to a C-shaped clamp 803. A locking rod 804 is fixedly connected to one side of the inner wall of the C-shaped clamp 803.

[0033] The rotating threaded rod 802 drives the C-shaped clamp 803 to move, and then the movement of the C-shaped clamp 803 drives the locking rod 804 to disengage from the sealing plate 5, thereby driving the sealing plate 5 to seal the opening of the outer shell 1.

[0034] Specifically, such as Figure 2 As shown, the other end of the two locking rods 804 is provided with a sealing plate 5, and one side of the sealing plate 5 is fitted with the opening on the front of the outer casing 1.

[0035] Specifically, such as Figure 1 As shown, support plates 9 are fixedly connected to both sides of the bottom of the outer casing 1.

[0036] 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.
