[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ,in, Figure 1 A schematic diagram of a preferred embodiment of the hot-melting device for powder metallurgy provided by this utility model; Figure 2 for Figure 1 The front sectional view shown is illustrated. Figure 3 for Figure 1 The diagram shows a partial sectional view. Figure 4 for Figure 1 The diagram shown is an exploded view of the internal structure. Figure 5 for Figure 4 The enlarged schematic diagram of part A shown below; Figure 6 for Figure 4 The enlarged schematic diagram of section B is shown below; Figure 7 for Figure 4 The enlarged schematic diagram of section C is shown. The hot-melt device for powder metallurgy includes: a heating component 1 and a heating frame 11. A driving component 2 is arranged on the left side of the heating component 1. A counter-stirring component 3 is arranged outside the driving component 2. A positioning support component 4 is arranged outside the heating component 1. A rotation component 5 is arranged outside the heating component 1.

[0024] The drive assembly 2 includes a cover plate 21 and a support frame 22. The cover plate 21 is located on the left side of the heating assembly 1. The support frame 22 is installed on the top of the heating frame 11. A rotary motor 23 is installed on the top of the support frame 22. A rotating gear 24 is fixedly connected to the output end of the rotary motor 23. A main shaft 25 is fixedly connected to the right side of the rotating gear 24. The main shaft 25 passes through the heating assembly 1 and extends into it. Transmission gears 26 are symmetrically arranged on the outer surface of the rotating gear 24. The outer surface of the transmission gears 26 meshes with the outer surface of the rotating gear 24. An auxiliary shaft 27 is fixedly connected to the right side of the rotating gear 24. The auxiliary shaft 27 passes through the heating assembly 1 and extends into it.

[0025] The cover plate 21 is installed on the left side of the heating assembly 1 via a threaded connection, facilitating disassembly and maintenance, and serving both protective and positioning functions. The support frame 22 is installed on the top of the heating frame 11, providing stable support for the rotary motor 23. The rotary motor 23 serves as a power source, and its output gear 24 and transmission gear 26 are based on the gear meshing principle. When the rotary gear 24 rotates, it drives the symmetrically arranged transmission gear 26 to rotate synchronously in opposite directions through inter-tooth meshing, thus achieving power distribution. The main shaft 25 and auxiliary shaft 27, fixed to the right side of the rotary gear 24, extend through the heating assembly 1 into the interior, and their ends are rotatably connected to the positioning part on the right side of the inner wall of the heating assembly 1 to ensure rotational stability. The rotation of the main shaft 25 and auxiliary shaft 27 drives the opposing stirring assembly 3 to operate, forming an opposing stirring effect to mix the metal powder in the heating assembly 1.

[0026] The opposing stirring assembly 3 includes a circular block 31, which is mounted on the outer surface of the main shaft 25 and the auxiliary shaft 27. A support block 32 is mounted on the outer surface of the circular block 31, and a ring block 33 is mounted at the end of the support block 32. A stirring plate 34 is provided on the outer surface of the ring block 33.

[0027] The circular blocks 31 are respectively installed on the outer surfaces of the main shaft 25 and the auxiliary shaft 27, and are staggered on the main shaft 25 and the auxiliary shaft 27. The ends of the support blocks 32 on the outer surfaces are connected to the ring blocks 33, forming a multi-layer three-dimensional structure. When the main shaft 25 and the auxiliary shaft 27 rotate in opposite directions under the drive of the drive assembly 2, the stirring plate 34 on the outer surface of the ring block 33 rotates in opposite directions synchronously. Through the staggered layout and the reverse rotation, the stirring plate 34 forms a counter-stirring flow field inside the heating assembly 1, disperses the powder agglomerates through radial shear force, and realizes the exchange and mixing of powders at different heights by using axial thrust.

[0028] The positioning support component 4 includes an annular groove 41, which is symmetrically opened on the outer surface of the heating component 1. A circular block 42 is slidably connected inside the annular groove 41, and a support column 43 is fixedly connected to the outer surface of the circular block 42. The bottom of the support column 43 is fixedly connected to the top of the heating frame 11.

[0029] A rotatable support structure is formed by the annular groove 41 symmetrically opened on the outer surface of the heating component 1 and the circular block 42 slidably connected inside. The bottom of the support column 43 on the outer surface of the circular block 42 is fixedly connected to the heating frame 11. The heating component 1 provides stable radial support to prevent it from shaking or shifting. The heating component 1 can rotate autonomously through the sliding cooperation between the annular groove 41 and the circular block 42, ensuring that the heating component 1 rotates smoothly under the drive of the self-rotating component 5.

[0030] The self-rotating component 5 includes a circular ring tooth block 51 and a mounting plate 52. The circular ring tooth block 51 is mounted on the outer surface of the heating component 1, and the mounting plate 52 is mounted on the inner side of the heating frame 11. A rotating motor 53 is fixedly connected to the top of the mounting plate 52, and a drive gear 54 is fixedly connected to the output end of the rotating motor 53. The outer surface of the drive gear 54 meshes with the outer surface of the circular ring tooth block 51.

[0031] The ring toothed block 51 installed on the outer surface of the heating assembly 1 meshes with the drive gear 54 at the output end of the rotating motor 53 on the top of the mounting plate 52. When the rotating motor 53 is started, the drive gear 54 drives the ring toothed block 51 to rotate through inter-tooth transmission, thereby causing the heating assembly 1 to rotate around its own axis. The mounting plate 52 is fixed to the inner side of the heating frame 11, providing a stable support for the rotating motor 53 and ensuring the stability of power transmission.

[0032] The outer surface of the opposing stirring assembly 3 is provided with a cleaning assembly 6. The cleaning assembly 6 includes two ring pillars 61, which are symmetrically installed on the outer surface of the auxiliary shaft 27. The auxiliary shaft 27 passes through the ring pillars 61 and extends to their outside. A scraping assembly 62 is installed at the end of the ring pillars 61. The outer surface of the scraping assembly 62 is slidably connected to the inner wall of the heating assembly 1.

[0033] Two ring supports 61 are symmetrically installed on the outer surface of the auxiliary shaft 27, and the outer surface of the scraping component 62 at its end slides against the inner wall of the heating component 1. When the auxiliary shaft 27 rotates with the drive component 2, it drives the ring supports 61 and the scraping component 62 to rotate synchronously. Through the sliding contact between the scraping component 62 and the inner wall of the heating component 1, the molten powder and residues attached to the inner wall of the heating component 1 are continuously removed, avoiding the accumulation of materials that affect the stirring efficiency and heating uniformity. At the same time, it reduces the wear and tear on the equipment after the residual materials solidify, and ensures the long-term stable operation of the hot melt device.

[0034] The working principle of the hot-melting device for powder metallurgy provided by this utility model is as follows: First, the operator pours metal powder into the heating component 1 through the feed port at the top, completing the raw material feeding. At this time, the powder is in a loosely piled state and requires further processing to achieve uniform mixing and hot melting. Then, the drive component 2 and the rotation component 5 are started to initiate the efficient processing flow. After the drive component 2 starts operating, it provides strong power to the opposing stirring component 3, causing it to stir in opposite directions inside the heating component 1. Unlike the drawback of traditional unidirectional stirring which easily forms fixed vortices, opposing stirring can apply force to the powder from multiple directions, strongly breaking up the aggregated powder clumps and promoting full contact and mixing between powders of different components. After the rotation component 5 starts, it drives the heating component 1 to rotate externally, allowing the powder to continuously change its position and trajectory as it rotates with the heating component 1, further enhancing the mixing effect. At the same time, it allows the powder to receive heat conduction more comprehensively and evenly, avoiding local overheating or underheating. Finally, the positioning support component 4 ensures that the heating component 1 remains stable during rotation, preventing the stirring effect from deteriorating or causing equipment failure due to shaking or displacement. After the metal powder is fully mixed and melted, it is discharged through the discharge port on the side of the heating component 1.

[0035] Compared with related technologies, the hot-melting device for powder metallurgy provided by this utility model has the following advantages:

[0036] This utility model provides a hot-melting device for powder metallurgy. The heating component 1 is supported by the heating frame 11 and the positioning support component 4. The heating component 1 is rotated by the rotation component 5 through the internal structure of the positioning support component 4. The driving component 2 provides power to the opposing stirring component 3, so that it stirs inside the heating component 1. The cooperation of each component breaks the unidirectional flow restriction, improves the uniformity of heat conduction and stirring efficiency, and reduces local overheating and uneven mixing.
