Description

Technical Field

[0001] The present application belongs to the technical field of screening devices, and in particular, relates to a powder screening machine for magnet preparation. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. Powder metallurgy technology can also be used to prepare magnets. When preparing magnets by powder metallurgy, a powder sifter is required to screen the metal powder.

[0003] The existing foreign patent with publication number TWI 832719B, a screening device includes a barrel tank, a screening module and an electromagnet. The screening module is located in the barrel tank and includes a screen, a permanent magnet and a magnetic induction element. The permanent magnet is fixed on the upper surface or the lower surface of the screen. The magnetic induction element is fixed on the inner wall of the barrel tank, and the curved portion of the magnetic induction element is located below the permanent magnet. The electromagnet is located around the magnetic induction element and provides an alternating magnetic field. The electromagnet is configured with an electromagnetic induction magnetic induction element.

[0004] Although the above-mentioned screening device can realize powder screening, the screened powders are all non-magnetic or non-magnetic conductive materials. Now it is necessary to screen magnetic powder, and the magnetic parts used to provide vibration of the screen will affect the screening of the magnetic powder. Improvements are made to this. Summary of the invention

[0005] The purpose of this application is to provide a powder screening machine for magnet preparation in order to solve the above-mentioned technical problems, and to improve the screening effect by vibrating the screen.

[0006] The present application provides a powder sieving machine for preparing magnets, including a powder sieving device body, wherein the powder sieving device body includes:

[0007] The barrel has one end connected to the feed pipe and the other end connected to the discharge pipe;

[0008] A plurality of screens are provided and distributed in the cylinder body;

[0009] A vibration mechanism is installed on the cylinder body and connected to the screen, and the vibration mechanism includes a connecting pipe, a vibration seat, a rotating member, a first spring, and a driving structure;

[0010] Among them, one end of the connecting pipe is connected to the center position of the screen, and the other end of the connecting pipe extends outside the cylinder body. The vibration seat is provided with a first slide groove, and the rotating member is provided with a first sliding portion corresponding to the first slide groove. The first spring is against the vibration seat, and the driving structure is connected to the rotating member.

[0011] The magnetic powder enters the barrel through the feed pipe and is discharged from the discharge pipe after being screened by the screen. The screen adopts different mesh sizes. The closer to the feed pipe, the larger the mesh size. When the magnetic powder is placed on the screen, the screen is vibrated by the vibration mechanism to achieve efficient screening of the screen. The driving structure rotates the rotating part, and the rotation of the rotating part causes the first sliding part to move in the first slide groove. By cooperating with the first spring, the vibration seat is reciprocated to knock, thereby achieving vibration of the screen.

[0012] Furthermore, the first chute includes:

[0013] Oblique groove;

[0014] vertical slots;

[0015] Wherein, the oblique grooves and the vertical grooves are distributed on the rotating part.

[0016] The first slide groove is composed of an oblique groove and a vertical groove. When the first sliding part is placed in the oblique groove and moves, the vibration seat moves and compresses the first spring. When the first sliding part is placed in the vertical groove, it is reset under the action of the first spring, and the vibration seat reciprocates to achieve vibration.

[0017] Furthermore, the driving structure includes:

[0018] Drive motor;

[0019] A transmission shaft connected to a driving motor;

[0020] The transmission gear is respectively installed on the transmission shaft and the rotating part.

[0021] The driving motor drives the transmission shaft to rotate. The driving motor is installed on the outer wall of the cylinder body. The transmission gear adopts bevel gears and is respectively installed on the transmission shaft and the rotating part, so that the rotating part can rotate.

[0022] Furthermore, the connecting pipe comprises:

[0023] An inner tube, placed in the connecting tube;

[0024] A discharge channel is disposed between the inner tube and the connecting tube;

[0025] Wherein, the driving structure, the rotating part and the vibration seat are installed in the inner tube.

[0026] The driving structure, rotating parts and vibration seat are installed in the inner tube, and the driving structure, rotating parts and vibration seat are protected by the inner tube. The magnetic powder blocked by the screen is discharged from the discharge channel to ensure the continuous screening effect of the corresponding screen. The discharge channel is connected to the negative pressure device.

[0027] Furthermore, the inner tube comprises:

[0028] Valve seat;

[0029] A second sliding portion is disposed on the inner surface of the inner tube;

[0030] a second spring, disposed between the valve seat and the inner tube;

[0031] Among them, the connecting pipe is provided with a discharge port corresponding to the valve seat, the valve seat is provided with a second slide groove corresponding to the second sliding part, the second slide groove is placed on the outer wall surface of the valve seat, the inner surface of the valve seat is provided with a limiting groove, and the vibration seat is provided with a limiting part corresponding to the limiting groove.

[0032] The valve seat and the vibration seat are movably connected via a limit groove and a limit part. When the rotating part rotates forward, the vibration seat moves along the axial direction to realize the vibration effect. When the rotating part reverses, the first sliding part is placed in the vertical groove and abuts against the side wall of the vertical groove. The vibration seat drives the valve seat to rotate. Through the structure of the second sliding groove and the second sliding part between the valve seat and the inner tube, the valve seat opens the discharge port, and the magnetic powder intercepted on the screen enters the discharge channel. When the vibration seat is in a vibrating state, its vibration is mainly generated by the collision between the valve seat and the vibration seat.

[0033] Furthermore, the screen has a taper of 85-89°.

[0034] By setting the screen to have a taper of 85-89°, the magnet powder intercepted by the screen can be gathered in the middle position. When the valve seat is opened, the magnet powder can quickly enter the discharge channel.

[0035] The beneficial effects of this application are:

[0036] 1. When the magnetic powder is placed on the screen, the screen is vibrated by the vibration mechanism to achieve efficient screening of the screen.

[0037] 2. The driving structure is used to rotate the rotating member, and the rotating member rotates to move the first sliding part in the first sliding groove, and cooperates with the first spring to make the vibration seat reciprocate and knock, thereby realizing the vibration of the screen.

[0038] 3. When the rotating part rotates forward, the vibration seat moves along the axial direction to realize the vibration effect. When the rotating part rotates reversely, the first sliding part is placed in the vertical groove and abuts against the side wall of the vertical groove. The vibration seat drives the valve seat to rotate. Through the structure of the second sliding groove and the second sliding part between the valve seat and the inner tube, the valve seat opens the discharge port. BRIEF DESCRIPTION OF THE DRAWINGS
