Description

Technical Field

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

[0002] In the field of metal powder processing, briquetting machines are commonly used to compress metal powder into spherical shapes for easy transportation, storage, or subsequent smelting. Traditional metal powder briquetting machines typically include a pre-compression mechanism and a briquetting roller assembly. However, in actual use, metal powder is prone to clogging during feeding and conveying, especially inside the working chamber. Powder may accumulate above the briquetting roller assembly or near the feed inlet, leading to uneven feeding, unstable briquetting quality, and even equipment shutdown. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problem that metal powder is prone to blockage during feeding and conveying in the prior art, especially in the working box, where powder may accumulate above the briquetting roller group or near the feed inlet, resulting in uneven feeding, unstable briquetting quality, and even equipment shutdown, a metal powder briquetting machine is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a metal powder briquetting machine, including a working box, a pre-pressing mechanism, a drive motor, a briquetting roller group and an anti-blocking mechanism, wherein the output end of the pre-pressing mechanism is connected to the feed port on the top surface of the working box, the pre-pressing mechanism and the working box are fixedly connected, and the pre-pressing mechanism is used to pre-press the metal powder. Both the anti-blocking mechanism and the ball-pressing roller assembly are arranged inside the working chamber. The anti-blocking mechanism is located above the ball-pressing roller assembly and includes a drive shaft and anti-blocking blades. The drive shaft and the working chamber are rotatably connected. The anti-blocking blades are arranged on the drive shaft and are used to agitate the metal powder. The drive motor and the working chamber are fixedly connected. The drive motor is located outside the working chamber. The output end of the drive motor is connected to the drive shaft and the ball-pressing roller assembly. Through the spiral conveying shaft in the pre-pressing mechanism and the pre-pressing chamber, uniform compression and continuous conveying of the metal powder are achieved, ensuring that the powder has a consistent density before entering the ball-pressing roller assembly, thereby improving the ball-pressing quality. The anti-clogging mechanism includes an anti-clogging blade, an upper anti-clogging component, and a lower anti-clogging component. It can continuously agitate the metal powder, prevent the powder from accumulating in the working chamber, avoid clogging problems, and ensure production continuity.

[0005] To address the issues of discontinuous powder conveying and uneven pre-compression in the pre-compression mechanism, the mechanism further includes a pre-compression motor, a screw conveyor shaft, and a pre-compression housing. The pre-compression housing and the working housing are fixedly connected, the discharge port of the pre-compression housing is connected to the inlet of the working housing, the pre-compression motor is fixedly connected to the pre-compression housing, the screw conveyor shaft is arranged inside the pre-compression housing, and the output end of the pre-compression motor is drively connected to the screw conveyor shaft.

[0006] To address the issues of uneven powder distribution and poor flow within the pre-compression chamber, the pre-compression chamber further includes a converging section that tapers inward from top to bottom and a pre-compression section that matches the screw conveyor shaft. The converging section is located above the pre-compression section, with its bottom surface and top surface fixedly connected. The pre-compression section is fixedly connected to the working chamber, and its outlet is connected to the inlet of the working chamber. The screw conveyor shaft passes through the converging section and extends into the pre-compression section.

[0007] To address the issue of powder accumulating in the working chamber, a further improvement is made by making the outlet size of the pre-compression section smaller than the internal cavity size of the working chamber.

Each lower anti-blocking component includes a lower anti-blocking plate and a lower elastic element. The lower anti-blocking plate is rotatably connected to the side wall of the working chamber. The lower anti-blocking plate tilts downwards towards the center of the ball-pressing roller assembly. The lower anti-blocking plate guides the metal powder to the ball-pressing roller assembly. One end of the lower elastic element is fixedly connected to the working chamber, and the other end is fixedly connected to the lower anti-blocking plate.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] like Figure 1 This is a schematic diagram of the structure of the present invention. A metal powder briquetting machine includes a working box 1, a pre-pressing mechanism 2, a drive motor 3, a briquetting roller group 4, and an anti-blocking mechanism 5. The output end of the pre-pressing mechanism 2 is connected to the feed port on the top surface of the working box 1. The pre-pressing mechanism 2 and the working box 1 are fixedly connected. The pre-pressing mechanism 2 is used to pre-press the metal powder. The ball pressing roller group 4 includes an active ball pressing roller and a driven ball pressing roller, on which multiple hemispherical dies are evenly distributed. When the dies of the two ball pressing rollers are aligned in the ball pressing meshing area, they together form a complete spherical cavity. The output end of the drive motor 3 is connected to the active ball pressing roller to drive it to rotate, and synchronously drives the driven ball pressing roller to rotate in opposite directions through the drive gear pair. The active ball pressing roller and / or the driven ball pressing roller are connected to the working box 1 through the bearing seat.

[0016] Both the anti-blocking mechanism 5 and the ball-pressing roller group 4 are arranged inside the working box 1. The anti-blocking mechanism 5 is located above the ball-pressing roller group 4. The anti-blocking mechanism 5 includes a drive shaft 51 and an anti-blocking blade 52. The drive shaft 51 is rotatably connected to the working box 1. The anti-blocking blade 52 is arranged on the drive shaft 51 and is used to agitate the metal powder. The drive motor 3 is fixedly connected to the working box 1 and is located outside the working box 1. The output end of the drive motor 3 is connected to the drive shaft 51 and the ball-pressing roller group 4. Through the spiral conveying shaft 22 and the pre-pressing box 23 in the pre-pressing mechanism 2, the metal powder is uniformly compressed and continuously conveyed, ensuring that the powder has a consistent density before entering the ball-pressing roller group 4, thereby improving the ball-pressing quality. The anti-blocking mechanism 5 includes an anti-blocking blade 52, an upper anti-blocking component 54, and a lower anti-blocking component 53, which can continuously agitate the metal powder, prevent the powder from accumulating in the working box 1, avoid blockage problems, and ensure production continuity.

[0017] like Figure 1 As shown, the pre-compression mechanism 2 includes a pre-compression motor 21, a screw conveyor shaft 22, and a pre-compression chamber 23. The pre-compression chamber 23 is fixedly connected to the working chamber 1. The discharge port of the pre-compression chamber 23 is connected to the inlet of the working chamber 1. The pre-compression motor 21 and the pre-compression chamber 23 are fixedly connected. The screw conveyor shaft 22 is arranged inside the pre-compression chamber 23. The output end of the pre-compression motor 21 is connected to the screw conveyor shaft 22 for transmission. By using the pre-compression motor 21, the screw conveyor shaft 22, and the pre-compression chamber 23, continuous compression and conveying of powder can be achieved, ensuring the pre-compression effect and improving the quality of the briquettes.

[0018] like Figure 1 As shown, the pre-compression chamber 23 includes a converging section 231 that tapers inward from top to bottom and a pre-compression section 232 that matches the screw conveyor shaft 22. The converging section 231 is located above the pre-compression section 232. The bottom surface of the converging section 231 and the top surface of the pre-compression section 232 are fixedly connected. The pre-compression section 232 is fixedly connected to the working chamber 1. The discharge port of the pre-compression section 232 is connected to the inlet of the working chamber 1. The screw conveyor shaft 22 passes through the converging section 231 and extends into the pre-compression section 232. The converging section 231 of the pre-compression chamber 23 guides the powder to concentrate. The pre-compression section 232 matches the screw conveyor shaft 22 to ensure that the powder is effectively compressed and smoothly conveyed.

[0019] The outlet size of the pre-compression section 232 is smaller than the inner cavity size of the working box 1, which allows the powder to enter in a concentrated manner. Secondly, it provides a diffusion gap for the entering powder, reducing the occurrence of blockage.

[0020] like Figure 2 As shown, the anti-blocking mechanism 5 includes several lower anti-blocking components 53, which are located between the ball-pressing roller group 4 and the anti-blocking blade 52. The lower elastic element 532 is a spring. The lower anti-blocking component 53 includes a lower anti-blocking plate 531 and a lower elastic element 532. The lower anti-blocking plate 531 is rotatably connected to the side wall of the working box 1. The lower anti-blocking plate 531 is inclined from top to bottom towards the center of the ball-pressing roller group 4. The lower anti-blocking plate 531 is used to guide the metal powder to the ball-pressing roller group 4. One end of the lower elastic element 532 is fixedly connected to the working box 1, and the other end is fixedly connected to the lower anti-blocking plate 531. The lower anti-blocking plate 531 guides the powder to the ball-pressing roller group 4. The lower elastic element 532 allows the plate to vibrate, prevents powder adhesion, ensures that the powder enters the ball-pressing area evenly, and can also provide a diffusion gap for the metal powder under the disturbance of the anti-blocking blade 52 to avoid jamming.

[0021] like Figure 2 As shown, the anti-blocking mechanism 5 includes an upper anti-blocking component 54, which includes an upper anti-blocking plate 541 and an upper elastic element 542. The upper elastic element 542 is a spring. The upper anti-blocking plate 541 is rotatably connected to the inner top surface of the working box 1. The upper anti-blocking plate 541 is located on the side of the feed inlet of the working box 1. The upper anti-blocking plate 541 is inclined from top to bottom away from the center of the ball pressing roller group 4. One end of the upper elastic element 542 is fixedly connected to the working box 1, and the other end is fixedly connected to the upper anti-blocking plate 541. The vibration and airflow impact generated by the anti-blocking blade 52 will be transmitted to the movable upper and lower anti-blocking plates 541 and 531, causing them to vibrate or swing slightly. This not only effectively shakes off the powder attached to the plate surface, but also periodically forms diffusion gaps, causing the accumulated metal powder to disintegrate. This completely avoids the problem of mechanism jamming caused by powder compaction, and realizes active and adaptive anti-blocking.

[0022] Working process: Metal powder enters the pre-compression chamber 23 from the feed port of the pre-compression mechanism 2. The pre-compression motor 21 starts and drives the screw conveyor shaft 22 to rotate. The screw conveyor shaft 22 compresses the powder in the pre-compression chamber 23 and conveys it forward. The collecting section 231 of the pre-compression chamber 23 guides the powder to concentrate into the pre-compression section 232. The pre-compression section 232 further compresses the powder and sends it into the feed port of the working chamber 1 through the discharge port. After the powder enters the working chamber 1, the drive motor 3 simultaneously drives the transmission shaft 51 of the anti-blocking mechanism 5 and the ball-pressing roller group 4. The transmission shaft 51 drives the anti-blocking blade 52 to rotate at high speed, which mainly disturbs the falling powder flow and breaks the initial accumulation trend. The vibration and airflow impact generated by the anti-blocking blade 52 will be transmitted to the movable upper and lower anti-blocking plates 541 and 531, causing them to vibrate or swing slightly. This not only effectively shakes off the powder attached to the plate surface, but also periodically forms diffusion gaps, causing the accumulated metal powder to disintegrate. This completely avoids the problem of mechanism jamming caused by powder compaction, and realizes active and adaptive anti-blocking, thereby fundamentally avoiding the occurrence of jamming. The powder, after being sufficiently agitated and diffused, is reliably guided by the lower anti-blocking plate 531 to the biting area of ​​the ball pressing roller group 4. The ball pressing roller group 4 rotates under the drive of the drive motor 3, pressing the loose and uniform powder into a ball shape. Throughout the process, the anti-blocking mechanism 5 ensures the extremely smooth flow of powder. The pressed spheres are discharged from below the ball pressing roller group 4, completing the ball pressing process.

[0023] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
