Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and specifically to a cemented carbide mixing device. Background Technology

[0002] The cemented carbide mixing device is a crucial part of cemented carbide production. Its performance and efficiency directly affect the quality and cost of the final product. The motor drives the stirring blades to rotate, and the blades push the material in the material to make circular and up-and-down movements, so that the cemented carbide raw materials of different compositions collide, interweave and tumble with each other, achieving uniform mixing.

[0003] The existing technology has the following problems:

[0004] Existing equipment cannot adequately stir cemented carbide during use. Cemented carbide is typically composed of multiple metallic or non-metallic components. Insufficient stirring can lead to uneven distribution of these components, resulting in localized areas with excessive or insufficient amounts of certain components. Inadequate stirring makes it difficult to achieve uniform mixing, which can easily lead to microstructural defects such as pores and cracks during subsequent sintering processes. Furthermore, existing equipment cannot quickly disassemble and install the feed pipe. During production, when it is necessary to change to different types or batches of cemented carbide raw materials, the inability to quickly disassemble and install the feed pipe will result in prolonged equipment downtime. Because the feed pipe cannot be quickly disassembled for thorough cleaning and maintenance, residual raw materials or impurities may accumulate inside the feed pipe. During the next use, these impurities may mix into the new raw materials, affecting the purity and quality of the product. Utility Model Content

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1-2As shown, this utility model provides a cemented carbide mixing device, including a storage tank 1. A motor 4 is fixedly connected to the upper side of the storage tank 1. A snap-fit ​​mechanism 5 is provided on the upper side of the storage tank 1. A feed pipe 6 is movably connected to the upper side of the snap-fit ​​mechanism 5. Multiple support columns 2 are fixedly connected to the lower side of the storage tank 1. A discharge pipe 3 is fixedly connected to the lower side of the storage tank 1.

Several stirring rods 8 are fixedly connected to the outer wall of the rotating shaft 7. In the process of using the device, raw materials are first injected into the storage tank 1 through the feed pipe 6, and then the raw materials are stirred.

[0024] like Figure 2-4 As shown, this utility model provides a technical solution: Preferably, a drive shaft 10 is fixedly connected to the output end of the motor 4. Multiple limiting strips 11 are fixedly connected to the outer wall of the drive shaft 10. The outer wall of the limiting strips 11 is slidably connected to the rotating shaft 7. A first bevel gear 14 is fixedly connected to the outer wall of the drive shaft 10. Two second bevel gears 15 are meshed with the outer wall of the first bevel gear 14. A connecting shaft 12 is fixedly connected to the side of the second bevel gear 15 away from the first bevel gear 14. A turntable 17 is fixedly connected to the other end of the connecting shaft 12. A connecting plate 18 is rotatably connected to the eccentric part of the turntable 17. A connecting plate 13 is rotatably connected to the other end of the connecting plate 18. Two support plates 16 are fixedly connected to the upper side of the inner wall of the fixed column 9. The outer wall of the connecting shaft 12 is rotatably connected to the support plates 16. An annular groove 20 is formed on the outer wall of the rotating shaft 7. A fixing ring 19 is fixedly connected to the inner surface of the connecting plate 13. The outer wall of the fixing ring 19 is rotatably connected to the annular groove 20. During the stirring process... In the process, motor 4 can be started first. Motor 4 can drive drive shaft 10 to rotate. When drive shaft 10 rotates, it can drive limit bar 11 to rotate. Limit bar 11 can drive rotating shaft 7 to rotate, thus driving stirring rod 8 to rotate and stirring the alloy inside storage tank 1. At the same time, drive shaft 10 can also drive first bevel gear 14 to rotate. The rotation of first bevel gear 14 can simultaneously drive two second bevel gears 15 to rotate, thus driving turntable 17 to rotate through connecting shaft 12. Since connecting plate 18 is located at the eccentric position of turntable 17, when connecting plate 18 rotates, it can drive connecting plate 13 to move up and down. The cooperation between fixed ring 19 and annular groove 20 can drive rotating shaft 7 to move up and down, fully stirring the raw materials inside storage tank 1. Uniform stirring helps the components to mix better, improving the quality of cemented carbide in subsequent sintering and other processes.

[0025] like Figure 5As shown, this utility model provides a technical solution: Preferably, the snap-fit ​​mechanism 5 includes a snap-fit ​​post 51, two knobs 58 are rotatably connected to the upper side of the snap-fit ​​post 51, a threaded rod 53 is fixedly connected to the lower side of the knobs 58, a lifting block 57 is threadedly connected to the outer wall of the threaded rod 53, a rotating plate 52 is rotatably connected to the side of the lifting block 57 near the feed pipe 6, a sector block 54 is rotatably connected to the other end of the rotating plate 52, a slot 55 is provided on the outer wall of the feed pipe 6, two rotating rods 56 are fixedly connected to the inner wall of the snap-fit ​​post 51, the outer wall of the rotating rods 56 is rotatably connected to the sector block 54, and the side of the lifting block 57 away from the feed pipe 6 is slidably connected to the snap-fit ​​post 51, the outer wall of the sector block 54... Connected to the slot 55, during the connection and installation of the feed pipe 6, the feed pipe 6 can be inserted into the snap-fit ​​post 51 first. Then, the knobs 58 on both sides can be rotated. The knobs 58 can drive the threaded rod 53 to rotate. The rotation of the threaded rod 53 can drive the lifting block 57 to rise and fall. When the lifting block 57 rises and falls, it can drive the rotating plate 52 to rotate. The rotation of the rotating plate 52 can drive the sector block 54 to rotate on the rotating rod 56. When the sector block 54 rotates and snaps into the slot 55, the feed pipe 6 can be limited and fixed. It can be quickly disassembled for maintenance or replacement, avoiding long-term production interruptions due to feeding problems and ensuring the continuity of production.

[0026] The working principle of this cemented carbide mixing device will be explained in detail below.

[0027] like Figure 1-5As shown, during the use of the device, raw materials are first injected into the storage tank 1 through the feed pipe 6, and then the raw materials are stirred. During the stirring process, the motor 4 can be started first. The motor 4 can drive the drive shaft 10 to rotate. When the drive shaft 10 rotates, it can drive the limit bar 11 to rotate. The limit bar 11 can drive the rotating shaft 7 to rotate, thus driving the stirring rod 8 to rotate and stirring the alloy inside the storage tank 1. At the same time as the drive shaft 10 rotates, it can also drive the first bevel gear 14 to rotate. The rotation of the first bevel gear 14 can simultaneously drive the two second bevel gears 15 to rotate, thus driving the turntable 17 to rotate through the connecting shaft 12. Since the connecting plate 18 is located at the eccentric position of the turntable 17, when the connecting plate 18 rotates, it can drive the connecting plate 13 to move up and down. The fixed ring 19 and the annular groove 20 interact with each other. In conjunction with the rotating shaft 7, the raw materials inside the storage tank 1 can be thoroughly stirred. Uniform stirring helps to better mix the components, improving the quality of the cemented carbide in subsequent sintering and other processes. During the connection and installation of the feed pipe 6, the feed pipe 6 can be inserted into the clamping post 51 first. Then, the knobs 58 on both sides can be rotated. The knobs 58 can drive the threaded rod 53 to rotate. The rotation of the threaded rod 53 can drive the lifting block 57 to rise and fall. When the lifting block 57 rises and falls, it can drive the rotating plate 52 to rotate. The rotation of the rotating plate 52 can drive the sector block 54 to rotate on the rotating rod 56. When the sector block 54 rotates and is clamped into the slot 55, the feed pipe 6 can be limited and fixed, allowing for quick disassembly for maintenance or replacement, avoiding long-term production interruptions due to feeding problems, and ensuring the continuity of production.
