Description

Technical Field

[0001] This utility model belongs to the field of semi-solid metal manufacturing technology, specifically relating to a feeding device for a magnesium alloy semi-solid quantitative pulping machine. Background Technology

[0002] In the semi-solid processing of magnesium alloys, the semi-solid quantitative slurry machine is one of the core pieces of equipment. Its main function is to process metal raw material particles into semi-solid slurry and then transport it to the mold for molding. The feeding system of the existing semi-solid quantitative slurry machine usually consists of a feeding hopper, a conveying pipe and a conveying screw. During operation, metal raw material particles are fed into the conveying pipe through the feeding hopper. The external heating components of the conveying pipe heat and melt the metal raw material particles. Then, the heated and melted metal slurry is stably transported to the mold for molding through the rotating conveying screw. However, in actual production applications, the aforementioned feeding device has significant drawbacks: Metal raw material particles tend to accumulate when fed into the hopper, and some particles may agglomerate due to moisture or adhesion, causing blockages within the hopper. This not only interrupts the feeding process and affects production efficiency but may also lead to abnormal internal pressure in the hopper, damaging equipment components. Furthermore, blockages cause unstable material delivery, affecting the quantitative accuracy of subsequent metal slurry and ultimately resulting in fluctuations in the quality of the molded product. To address this issue, existing technologies often employ manual, periodic cleaning of the hopper to prevent blockages. This not only increases the workload of operators but also requires pausing equipment operation during cleaning, further reducing production efficiency and failing to fundamentally solve the material blockage problem.

Detailed Implementation

[0013] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1 to 4 This utility model provides a feeding device for a magnesium alloy semi-solid quantitative pulping machine, including... The chassis 2 provides a stable installation benchmark for subsequent components such as the material conveying pipe 5 and the screw drive assembly 3. At the same time, it can protect the core transmission components such as the conveying screw 310 inside the chassis 2, preventing external dust and impurities from entering or being accidentally touched by personnel, thus ensuring the safety of equipment operation and the service life of internal components. The conveying pipe 5, installed on the casing 2 and connected to the inside of the casing 2, enables metal particles to enter from the feed hopper 6 and be smoothly conveyed into the casing 2 to cooperate with the conveying screw 310 to complete the subsequent conveying operation. Installing the conveying pipe 5 on the casing 2 can ensure the installation stability of the conveying pipe 5 with the support of the casing 2, and prevent the pipe from shifting or shaking due to its own weight or material impact, thus ensuring the stability of the material conveying path. The feed hopper 6, which is connected to the inside of the conveying pipe 5, can serve as a temporary storage and transition structure for metal raw material particles, increasing the volume of the material input port, making it convenient for operators to feed metal particles in batches and avoiding frequent feeding. The anti-clogging component includes a first guide rod 8 and a second guide rod 9 rotatably mounted inside the feed hopper 6, providing a foundation for the subsequent installation of crushing components. The rotation of the two guide rods drives the crushing components to act on the material. The multiple guide rods can cover a wider area inside the feed hopper 6, and compared to a single guide rod, can more comprehensively handle materials in different positions within the feed hopper 6, reducing dead zones for material accumulation and structurally ensuring anti-clogging. Multiple first-group crushing components are mounted on the outer wall of the first guide rod 8, and multiple second-group crushing components are mounted on the outer wall of the second guide rod 9. The second-group crushing components are staggered with the first-group crushing components, and can crush metal particles in the feed hopper 6 as the guide rods rotate, solving the problem of material agglomeration. The staggered distribution of the two groups can avoid collisions and interference between the crushing components during rotation, while also connecting the crushing areas to achieve continuous and comprehensive crushing of materials, improving crushing efficiency and further reducing the risk of clogging.

[0015] In this embodiment, the first set of crushing components includes a plurality of first crushing blocks 83 disposed on the outer wall of the first guide rod 8, and the plurality of first crushing blocks 83 are equally spaced. The first crushing blocks 83 are crushing units that directly act on the material and can apply impact force and shear force to the agglomerated material through rotation to achieve agglomeration. The equal distribution of the plurality of first crushing blocks 83 can make the crushing force on the material evenly distributed during the rotation of the first guide rod 8, avoiding insufficient crushing of local materials or uneven force on the guide rod due to the concentration of crushing blocks, thus ensuring the crushing effect and the stability of the guide rod operation.

[0016] In this embodiment, the second set of crushing components includes a plurality of second crushing blocks 91 disposed on the outer wall of the second guide rod 9, and the plurality of second crushing blocks 91 are equally spaced. The second crushing blocks 91 can work together with the first crushing blocks 83 to crush the material, thereby enhancing the crushing capacity. The equally spaced distribution can ensure that the crushing force of the second guide rod 9 on the material is uniform, and at the same time, it complements the spacing of the first crushing blocks 83, ensuring that the material in the feed hopper 6 can be effectively acted upon by the crushing blocks no matter where it is located.

[0017] In this embodiment, a first transmission part 81 and a second transmission part 82 are also provided on the first guide rod 8, and a servo motor 7 is installed on the side surface of the feed hopper 6. The output shaft of the servo motor 7 passes through the feed hopper 6 and is connected to the first transmission part 81. The first transmission part 81 serves as the connection medium between the servo motor 7 and the first guide rod 8, and can stably transmit the power of the servo motor 7 to the first guide rod 8 to drive the first guide rod 8 to rotate. The servo motor 7 is installed on the side surface of the feed hopper 6, which is convenient for installation and subsequent maintenance and repair, and can also avoid occupying the internal space of the feed hopper 6 and affecting the material conveying.

[0018] In this embodiment, a fastening rod 820 is also included, which passes through the feed hopper 6 and is connected to the second transmission part 82. A first fixing tooth 8201 is provided on the fastening rod 820. The fastening rod 820 is connected to the second transmission part 82 and can transmit the rotational power of the first guide rod 8 to the fastening rod 820, thereby driving the first fixing tooth 8201 to rotate. The fastening rod 820 is set through the feed hopper 6 to ensure its coaxiality when rotating and to avoid abnormal meshing between the first fixing tooth 8201 and the subsequent second fixing tooth 92 due to the offset of the fastening rod 820. The first fixing tooth 8201, as a key structure for power transmission, provides a transmission basis for realizing the linkage between the first guide rod 8 and the second guide rod 9.

[0019] In this embodiment, a transmission rod is also provided on the second guide rod 9. The transmission rod is provided with a second fixed tooth 92 that meshes with the first fixed tooth 8201. The meshing of the second fixed tooth 92 with the first fixed tooth 8201 can transmit the power of the fastening rod 820 to the second guide rod 9, realizing the synchronous linkage between the first guide rod 8 and the second guide rod 9. There is no need to equip the second guide rod 9 with an additional drive component, simplifying the equipment structure and reducing equipment cost and energy consumption. Through gear meshing transmission, the rotation speed ratio of the two guide rods can be kept stable, ensuring the coordinated rotation rhythm of the crushing components and improving the coordination effect of crushing and guiding.

[0020] In this embodiment, multiple heating elements 4 are also provided on the outer wall of the conveying pipe 5 to heat the metal particles in the conveying pipe 5, causing the metal particles to gradually melt and form a semi-solid slurry. A first connecting rod 31 is rotatably provided inside the housing 2, and a conveying screw 310 is connected to the first connecting rod 31. A screw drive assembly 3 is installed on the housing 2 to drive the first connecting rod 31 to rotate. The screw drive assembly 3 serves as the power source for the conveying screw 310, providing a stable driving force to the first connecting rod 31 and ensuring that the rotation speed of the conveying screw 310 is controllable, thereby realizing the adjustment of the slurry conveying volume and meeting the quantitative conveying requirements under different production conditions. Installing it on the housing 2 facilitates the installation, fixation, and subsequent maintenance of the components. At the same time, it can form an integrated design with the internal structure of the housing 2, reducing the overall space occupied by the equipment. The base 1 installed at the bottom of the housing 2 improves the placement stability of the entire feeding device.

[0021] The working principle and usage process of this invention are as follows: The operator puts magnesium alloy raw material particles into the feed hopper 6; the servo motor 7 is started, which drives the first guide rod 8 to rotate through the first transmission part 81. The first crushing block 83 on the first guide rod 8 rotates synchronously. At the same time, through the second transmission part 82, the fastening rod 820 and the first fixing tooth 8201, the second fixing tooth 92 and the second guide rod 9 are meshed and rotated. The second crushing block 91 rotates with it. The two sets of crushing blocks work alternately to crush the agglomerated material and prevent blockage. The crushed material enters the conveying pipe 5, and the heating element 4 on the outer wall heats it, causing it to gradually melt into a semi-solid slurry; Start the screw drive assembly 3 to drive the first connecting rod 31 and the conveying screw 310 to rotate, and the conveying screw 310 will quantitatively convey the material to the subsequent molding stage.

[0022] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
