Description

Technical Field

[0001] The invention belongs to the technical field of wet-pressing magnetic tiles, and in particular is a quantitative feeding device for wet-pressing magnetic tiles located outside a mold. Background Art

[0002] Magnetic tiles are an industrial material with magnetic and waterproof properties. They are made through wet pressing and sintering processes. They have good anti-seepage, anti-compression and anti-freeze properties and are widely used in various permanent magnet motors. It can be said that the shadow of magnetic tiles can be seen in many advances in modern industry. At present, high-performance permanent magnet materials such as NdFeB magnetic tiles play an important role in new energy vehicles, wind power generation, aerospace and other high-tech fields. Only by promoting the transformation of the magnetic tile production industry towards high quality and high efficiency can we meet market needs.

[0003] Since the molding slurry contains a certain amount of water, the particles in the slurry are easy to turn in the magnetic field, so that a higher degree of orientation can be obtained, which is one of the key factors to improve the performance of magnetic tiles. However, the traditional injection method in which the injection head is located inside the mold often leads to uneven distribution of the slurry inside the mold due to the position and shape of the injection head. This uneven distribution not only affects the molding efficiency of the magnetic tiles, but may also cause inconsistent performance of the magnetic tiles during the wet pressing process. Therefore, a quantitative feeding device for wet pressing of magnetic tiles located outside the mold is proposed. Summary of the invention

[0014] The one-way feeding sleeve is connected to the pushing mounting head;

[0015] The storage bin is connected to the one-way feeding sleeve, and the control channel is connected to the storage bin;

[0022] In the present invention, the problem that the traditional feeding device is located in the mold, which leads to insufficient internal orientation of the magnetic tile during wet pressing molding and thus leads to insufficient performance of the formed magnetic tile is overcome, and the direct influence of the injection head on the slurry distribution inside the mold is effectively avoided, thereby ensuring the uniform distribution of the slurry during the wet pressing molding process, thereby improving the internal orientation of the magnetic tile, laying a solid foundation for improving the performance of the magnetic tile, and at the same time achieving precise control of the slurry injection amount and injection rate, thereby improving the stability and consistency of magnetic tile molding. Under the combined effect of uniform distribution and precise injection of the slurry, the magnetic tile can obtain better molding effect and higher performance during the wet pressing molding process.

[0034] In this embodiment, the quantitative injection head 3 includes a guide groove 3-1, an injection inlet 3-2, a control channel 3-3 and an electromagnetic ball valve 3-4, wherein the guide groove 3-1 is arranged on both sides of the rear half of the injection platform 2-2 and is symmetrically arranged. It should be noted that the guide groove 3-1 can cooperate with the support frame 2-1 so that the injection platform 2-2 can move up and down along the support frame 2-1, and the injection inlet 3-2 is arranged at the upper end of the front half of the injection platform 2-2, and the injection inlet 3-2 is connected with the feed pipe 1-2, and the connection must be tightened to prevent the slurry from leaking from the connection, the control channel 3-3 is installed on both sides of the front half of the injection platform 2-2 and is symmetrically arranged, and an air pressure tank is arranged inside the injection platform 2-2, and the air pressure tank is connected to multiple control channels 3-3. It should be noted that the air pressure tank is a prior art, and the slurry inside the storage bin 4-2 is squeezed into the mold by air pressure.

[0035] In this embodiment, the material storage component 4 includes a one-way feed sleeve 4-1 with a hollow interior and a storage bin 4-2, wherein the one-way feed sleeve 4-1 is connected to the push mounting head 2-4; the storage bin 4-2 is installed on the one-way feed sleeve 4-1, and a one-way valve can be set inside the one-way feed sleeve 4-1 to realize one-way downward feeding, allowing only one-way flow of slurry. It should be noted that the storage bin 4-2 is used for temporary storage of slurry coming in from the one-way feed sleeve 4-1, and the control channel 3-3 is connected to the storage bin 4-2 at one end away from the air pressure tank. The lower end of the storage bin 4-2 is provided with an electromagnetic ball valve 3-4, which is the key to controlling the amount of slurry, and controls the flow of slurry entering the mold by adjusting its size.

[0038] In this embodiment, the guide rail groove 3-1 is slidably connected to the support frame 2-1.

[0039] Working principle: The slurry first enters the injection platform 2-2 in the injection mechanism 2 below from the storage hopper 1-1 through the feed pipe 1-2, enters the inside of the one-way feed sleeve 4-1 from the push installation head 2-4 through the injection inlet 3-2, and enters the inside of the storage bin 4-2 through the one-way valve. The injection platform 2-2 can move up and down on the screw 6 under the action of the mobile drive mechanism 5. Specifically, the screw 6 is driven to rotate by the mobile drive mechanism 5-hopper 1, thereby adjusting the distance between the injection mechanism 2-injection mechanism 2 and its upper components and the mold platform in the storage component 4. In order to enable the slurry to be accurately injected into the mold, the retractable feed pipe 1-2 can meet the up and down movement of the injection platform 2-2. Then, by controlling the air pressure tank to generate pressure, it passes through the interior of the quantitative injection head 3-quantitative injection head 3 and enters the interior of the storage component 4-injection mechanism 2 to accelerate the slurry inside the storage component 4-injection mechanism 2 to flow out into the mold. The amount of slurry can be accurately controlled by the electromagnetic ball valve 3-4, thereby ensuring that the amount of slurry injected into the mold platform is consistent each time, ensuring that the wet-pressed magnetic tiles can have extremely high performance to meet production needs.
