Description

Technical Field

[0001] This invention relates to the field of target material production technology, specifically to an automatic feeding and powder distribution device for a vibrating powder machine. Background Technology

[0002] In the forming process of ITO rotary targets, powder needs to be loaded first to form a blank, and then the blank is sintered into a target material.

[0003] Patent document CN114407165A discloses a powder-loading device for an ITO rotating target, including a mold body and a drive mechanism. A mandrel is coaxially mounted inside the mold body, and ITO powder is filled between the mold body and the mandrel. A hammering mechanism is movably mounted vertically on the outer side of the mold body. The drive mechanism is detachably mounted at the lower end of the mold body and drives the mold body to rotate. In this invention, when producing the target blank, ITO powder is loaded into the cavity between the mold body and the mold mandrel. Then, the drive mechanism drives the mold body to rotate, while the hammering mechanism moves vertically to hammer the outer wall of the mold body, thus achieving omnidirectional hammering of the mold body. This ensures the density of the target blank, thereby improving the forming density of the ITO rotating target and guaranteeing the quality of the target. Furthermore, the use of a hammering mechanism for tapping and compaction not only saves labor but also improves powder loading efficiency.

[0004] The above-mentioned device has the following shortcomings: it cannot quickly and alternately fill powder during use, resulting in low powder filling efficiency; it cannot perform detailed proportioning of raw material ratio, weight, and particle size of powder, and cannot be flexibly adjusted; it cannot uniformly fill the cylindrical groove of the mold with powder in a cylindrical shape during filling, and cannot be quickly adjusted to adapt to molds of different diameters; at the same time, it cannot adapt to molds of different diameters when vibrating powder, resulting in low conveying efficiency. Summary of the Invention

[0019] As a further aspect of the invention, the inner wall of the guide cylinder, the inner wall of the outer connecting cylinder, and the inner wall of the powder outlet cylinder are all fixedly connected with a number of first needle rods, and the outer wall of the cylindrical section of the guide cylinder, the outer wall of the inner connecting cylinder, and the outer wall of the inner powder outlet cylinder are all fixedly connected with a number of second needle rods.

[0020] The beneficial effects of this invention are:

[0021] (1) During operation, the ITO target mold is positioned and rotated using two placement racks. When one placement rack holds the ITO target mold, it is immediately pushed into the working box and inside the support box by the first slides on both sides to fill the ITO target mold in the placement rack with powder. At the same time, the other placement rack is pushed out and moved to one end of the first slide, making it convenient to remove the filled ITO target mold and put in the replacement mold, thereby shortening the rotation interval and improving the filling efficiency. During filling, the vacuum pump generates suction to draw the powder from each pointed bottom barrel through each second powder inlet pipe and input it into the working box through the first powder inlet pipe for filling. The powder drawn in by each second powder inlet pipe is collected by the multi-channel confluencer. The material is fed and the feed rate is adjusted to achieve the desired ratio. When the particle size of the powder needs to be limited, it is graded and screened through a multi-layer screening mechanism, and the powder of each particle size is separately fed into each pointed-bottom bucket through each powder outlet. During filling, the multi-channel confluencer limits the filling, thereby filling the powder within a certain particle size range to optimize the raw material of the target material and improve the quality of the target material. The powder in the corresponding pointed-bottom bucket is weighed by a scale, and the weight of the powder filled each time is obtained by summing the weight reduction of the powder in each bucket after suction. The conveying volume of the second powder inlet pipe is controlled by the opening and closing of the valve, thereby accurately matching the type and particle size of the powder according to the formula, and thus quickly obtaining and controlling the filling amount each time.

[0022] (2) During operation, the first slide accurately moves the placement rack containing the mold to directly below the inner powder outlet cylinder. Then, the second slide moves the powder-holding cone downwards, causing the inner and outer powder outlet cylinders to extend into the cylindrical gap of the mold. Subsequently, powder is fed into the powder-holding cone through the first powder inlet pipe. The powder is guided into the mold through the gaps between the guide tube and the inner wall of the powder-holding cone, between the inner and outer connecting tubes, and between the inner and outer powder outlet cylinders. When the powder is conveyed to the powder-holding cone through the guide tube, it passes through the gaps between adjacent support plates and enters the powder-holding cone. The second guide cap ensures that the powder is evenly distributed at the bottom of the powder-holding cone. During powder holding, the guide tube and the guide sealing ring abut against the outlet of the powder-holding cone. The system is sealed for easy powder loading. Simultaneously, the second stator drives the second rotor, rotating the connecting sleeve and causing each flat stirring frame to rotate. This process evenly stirs the powder within the powder-loading cone, ensuring the powder is evenly distributed around the guide tube. During powder discharge, the guide tube separates from the guide sealing ring, maintaining a gap. Under the influence of gravity and the top discharge pressure, the powder falls evenly in a ring, maintaining a uniform powder distribution across the ring surface, thus ensuring uniform powder discharge. When the guide tube rotates at a constant speed driven by the first rotor, each second needle rod rotates at a constant speed, and the second needle rods continuously intersect with the first needle rods, preventing powder accumulation between the guide tube and the guide straight cylinder, between the inner and outer connecting cylinders, and between the inner powder discharge cylinder and the guide tube. At a certain point between the powder outlet cylinders, the powder is further evenly distributed in a ring, falls evenly, and fills the gap between the mold and the mold core evenly from bottom to top, resulting in a uniform distribution of powder throughout the final cylindrical target material. Simultaneously with the powder introduction, the vibrating mechanism strikes the mold, causing the powder to compact tightly. A baghouse vacuum cleaner draws air from the working box and support box, creating negative pressure to prevent dust leakage and protect workers. The second slide continuously moves the powder-holding cone upwards, maintaining a certain distance between the lower end of the inner powder outlet cylinder and the upper end formed by the powder accumulation. When the powder flow ends, the drive rod retracts, and the outer edge of the lower end of the frustum section of the guide cylinder aligns with the inner edge of the guide sealing ring. The material comes into contact with the mold, forming a seal. Simultaneously, the vacuum pump stops suction, thus stopping the conveying process. The material is guided through the upper end of the first guide cap, the frustum section of the guide cylinder, and the frustum structure of the inner wall of the guide sealing ring, allowing the powder to be input into the mold in a cylindrical shape. During conveying, the first rotor drives the guide cylinder, the inner connecting cylinder, and the inner powder outlet cylinder to rotate together, preventing blockage during powder conveying. By replacing the inner and outer powder outlet cylinders of different sizes and connecting them with the inner and outer connecting cylinders of different sizes, the material can be adapted to the size of different molds, enabling precise conveying and avoiding contamination. This reduces the undulation deviation of the powder's upper end face, ensuring uniform density throughout, reducing losses during subsequent trimming, and improving the yield rate.

[0023] (3) During operation, the stirring motor drives the scraper to stir and rotate the powder in the pointed bottom bucket, avoiding powder accumulation and adhesion, and facilitating the second powder inlet pipe to draw it out. The mold is clamped by each clamping vertical rod. The arc structure at the upper end of the clamping vertical rod facilitates the use and placement of the mold. When clamped, the inclined support rod rotates under force, pushing each pair of limit blocks in each limit groove to gather together, thereby adapting to molds of different diameters. The clamping vertical rod maintains the clamping force through the elastic force of the limit spring. At the same time, the mold is fully vibrated by the impact of the powder vibrating mechanism while maintaining stable support. The transmission turntable is rotated by the powder vibrating motor, which drives the transmission rod to periodically push the positioning cylinder to move back and forth. The moving resistance is reduced by the clamping roller. The powder vibrating hammer passes through the side wall of the support box and hits the side wall of the mold, thereby vibrating and compacting the powder in the mold. The position of the powder vibrating hammer is adjusted by rotating the powder vibrating screw to adapt to molds of different diameters. Attached Figure Description

[0038] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0039] Please see Figure 1-12As shown: An automatic feeding and powder distribution device for a vibrating powder mill includes a working box 1, a support box 2 below the working box 1, a multi-layer screening mechanism 3 on one side of the support box 2, several pointed-bottom barrels 4 evenly distributed at equal angles around the outer periphery of the multi-layer screening mechanism 3, a first sliding table 6 symmetrically arranged between the working box 1 and the support box 2, two placement racks 5 located between the two first sliding tables 6 and between the working box 1 and the support box 2, and a vibrating powder mechanism 7 installed in the middle of both the left and right sides of the support box 2. Bag vacuum cleaners 47 are installed on both the left and right sides of the support box 2. A scale 8 is installed at the bottom of the pointed bottom bucket 4. A vacuum suction machine 9 is installed directly above the multi-layer screening mechanism 3. The vacuum suction machine 9 is connected to the working box 1 through the first powder inlet pipe 10. The lower part of the vacuum suction machine 9 is connected to a multi-channel confluencer 11. Each port of the multi-channel confluencer 11 is connected to a second powder inlet pipe 12. Each drying layer of the multi-layer screening mechanism 3 is provided with a powder outlet 13. The pointed bottom bucket 4, the second powder inlet pipe 12 and the powder outlet 13 correspond one-to-one.

[0040] In this embodiment, the ITO target mold is positioned and rotated using two placement racks 5. When one placement rack 5 holds an ITO target mold, it is immediately pushed into the work box 1 and support box 2 via the first sliding tables on both sides, filling the ITO target mold in the placement rack 5 with powder. Simultaneously, the other placement rack 5 is pushed out and moved to one end of the first sliding table 6, facilitating the removal of the filled ITO target mold and the placement of the replacement mold, thus shortening the rotation interval and improving filling efficiency. During filling, a vacuum suction machine 9 generates suction, drawing powder from the pointed-bottom barrels 4 through the second powder inlet pipes 12 and inputting it into the work box 1 through the first powder inlet pipe 10. The filling process involves using a multi-channel confluencer 11 to collect the powder drawn in from each of the second powder inlet pipes 12 and adjusting the feed rate to achieve a specific ratio. When the particle size of the powder needs to be limited, it is graded and screened by a multi-layer screening mechanism 3, and each particle size is individually fed into a pointed-bottom bucket 4 through a powder outlet 13. During filling, the multi-channel confluencer 11 limits the filling to a specific particle size range, thereby optimizing the target material raw material and improving the quality of the target material. The powder in the corresponding pointed-bottom bucket 4 is weighed by a weighing scale 8, and the weight of the powder filled each time is obtained by summing the weight reduction of the powder in each bucket after suction, thus enabling rapid acquisition and control of the filling amount each time.

[0041] A powder-holding cone 18 is provided in the middle of the inner side of the working box 1. Second slides 17 are installed at each of the four corners of the working box 1. The second slides 17 are connected to the powder-holding cone 18 via connecting brackets 32. The powder-holding cone 18 is connected to the first powder inlet pipe 10 via a powder guiding hose 19. A supporting vertical rod 20 is installed in the middle of the inner side of the powder-holding cone 18. A driving push rod 22 is installed at the lower end of the supporting vertical rod 20. The driving push rod 22 is vertically downward. An annular frame 23 is fitted over the telescopic end of the driving push rod 22. A first stator 24 is installed on the annular frame 23. A first rotor 25 is fitted over the first stator 24. A guide tube 26 is fitted around the outer periphery of the first rotor 25. The guide tube 26 has a docking section, a frustum section, and a cylindrical section. The guide tube 26 is fitted around the outer periphery of the driving push rod 22. A first guide cap 21 is installed at the lower end of the supporting vertical rod 20 and around the docking section of the guide tube 26. The upper part of the first guide cap 21... The first guide cap 21 is shaped like a frustum and is fixedly connected to the support rod 20. The lower end of the first guide cap 21 is sealed and movably sleeved on the docking section of the guide tube 26. The bottom of the powder-holding cone 18 is fixedly connected to the guide tube 55. The upper inner side of the guide tube 55 is fixedly connected to the guide sealing ring 31. The lower end of the cylindrical section of the guide tube 26 is sealed and spliced ​​with the inner connecting tube 27. The lower end of the guide tube 55 is sealed and spliced ​​with the outer connecting tube 28. The lower end of the inner connecting tube 27 is sealed and spliced ​​with the inner powder outlet tube 29. The lower end of the outer connecting tube 28 is sealed and spliced ​​with the outer powder outlet tube 30. The lower diameter of the frustum section of the guide tube 26 and the diameter of the cylindrical section are both between the inner diameter and the outer diameter of the guide sealing ring 31. There are consistent gaps between the outer circumference of the cylindrical section of the guide tube 26 and the inner wall of the powder-holding cone 18, between the inner connecting tube 27 and the outer connecting tube 28, and between the inner powder outlet tube 29 and the outer powder outlet tube 30.

[0042] In this embodiment, during operation, the first slide 6 accurately moves the placement rack 5 containing the mold directly below the inner powder outlet cylinder 29. Then, the second slide 17 moves the powder-holding cone 18 downwards, allowing the inner powder outlet cylinder 29 and the outer powder outlet cylinder 30 to extend into the cylindrical gap of the mold. Powder is then fed into the powder-holding cone 18 through the first powder inlet pipe 10. The powder is guided into the mold through the gaps between the guide cylinder 26 and the inner wall of the powder-holding cone 18, between the inner connecting cylinder 27 and the outer connecting cylinder 28, and between the inner powder outlet cylinder 29 and the outer powder outlet cylinder 30. Simultaneously, the vibrating powder mechanism 7 strikes the mold, causing the powder to be tightly compacted. The baghouse vacuum cleaner 47 draws air from the working box 1 and the support box 2, creating negative pressure within them to prevent dust from escaping and protect the workers. The second slide 17 continuously moves upwards... The powder cone 18 maintains a certain distance between the lower end of the inner powder outlet 29 and the upper end formed by the powder accumulation. When the powder flow ends, the drive push rod 22 retracts, and the outer edge of the lower end of the frustum section of the guide tube 26 abuts against the inner edge of the guide sealing ring 31 to form a contact seal. At the same time, the vacuum pump 9 stops pumping, thereby stopping the conveying. The powder is guided by the frustum structure of the upper end of the first guide cap 21, the frustum section of the guide tube 26, and the inner sidewall of the guide sealing ring 31, so that the powder is input into the mold in a cylindrical shape. During conveying, the first rotor 25 drives the guide tube 26, the inner connecting tube 27, and the inner powder outlet 29 to rotate together to avoid blockage during powder conveying. By replacing the inner powder outlet 29 and the outer powder outlet 30 with different sizes, and connecting them with the inner connecting tube 27 and the outer connecting tube 28 with different sizes, it can adapt to the size of different molds.

[0043] A stirring motor 15 is installed at the bottom of the pointed-bottom bucket 4. The stirring motor 15 is vertically upward, and the upper end of the drive shaft of the stirring motor 15 passes through the bottom of the pointed-bottom bucket 4. The drive shaft of the stirring motor 15 is rotatably connected to the pointed-bottom bucket 4 in a sealed manner. A scraper 16 is installed at the upper end of the drive shaft of the stirring motor 15. The scraper 16 is slidably connected to the bottom of the pointed-bottom bucket 4. During operation, the stirring motor 15 drives the scraper 16 to stir and rotate the powder in the pointed-bottom bucket 4, so as to avoid the accumulation and adhesion of the powder and facilitate the suction of the second powder inlet pipe 12.

[0044] The placement frame 5 includes a placement prism 33. In this embodiment, the placement prism 33 has a prism-shaped edge structure. A clamping vertical rod 36 is provided in the middle of the placement prism 33. The clamping vertical rod 36 corresponds one-to-one with the four edges of the placement prism 33. A limiting groove 37 is provided in the middle of the clamping vertical rod 36. Limiting springs are installed at both ends of the limiting groove 37. Limiting blocks 38 are slidably connected in the limiting groove 37. The limiting blocks 38 correspond one-to-one with the limiting springs and are fixedly connected. The limiting block 38 is hinged with a diagonal brace 39. Each pair of diagonal braces 39 is hinged to the upper and lower ends of the four edges around each placement frame 33. The upper end of the clamping vertical rod 36 is arc-shaped. A support spring 34 is installed in the middle of the lower side of the placement frame 33. A support base plate 35 is installed at the upper end of the support spring 34. The outer periphery of the support base plate 35 is provided with positioning grooves that are evenly distributed at equal angles. The positioning grooves of the support base plate 35 are fitted into the clamping vertical rod 36 one by one.

[0045] In this embodiment, the mold is clamped by the clamping vertical rods 36. The arc-shaped structure at the upper end of the clamping vertical rods 36 facilitates the picking and placing of the mold. During clamping, the diagonal support rod 39 rotates under force, pushing each pair of limit blocks 38 in each limit groove 37 to converge, thereby accommodating molds of different diameters. The clamping vertical rods 36 maintain clamping force through the elastic force of the limit springs. At the same time, the elastic force of the limit springs and the support springs 34 ensures that the mold is fully vibrated by the impact of the powder vibration mechanism 7 while maintaining stable support.

[0046] The powder vibrating mechanism 7 includes a mounting box 40, in which a powder vibrating motor is installed. The powder vibrating motor is horizontally positioned. A transmission turntable 41 is installed at one end of the drive shaft of the powder vibrating motor. A transmission rod 42 is hinged to the edge of the transmission turntable 41. A positioning cylinder 44 is provided at the bottom of the inner side of the mounting box 40. Clamping rollers 43 are provided on both sides of the positioning cylinder 44. The clamping rollers 43 are rotatably connected to the mounting box 40 and are rollingly connected to the positioning cylinder 44. The end of the positioning cylinder 44 away from the transmission turntable 41 is hinged to the transmission rod 42. A powder vibrating screw 45 is threaded into the positioning cylinder 44. A powder vibrating hammer 46 is installed at the end of the powder vibrating screw 45 away from the transmission turntable 41. Through holes that mate with the powder vibrating screw 45 and the powder vibrating hammer 46 are respectively opened on both sides of the mounting box 40.

[0047] In this embodiment, the transmission turntable 41 is rotated by the vibrating powder motor, which drives the transmission rod 42 to periodically push the positioning cylinder 44 to reciprocate. The moving resistance is reduced by the clamping roller 43. The vibrating powder hammer 46 passes through the side wall of the support box 2 and strikes the side wall of the mold, thereby vibrating and compacting the powder in the mold. The position of the vibrating powder hammer 46 can be adjusted by rotating the vibrating powder screw 45 to adapt to molds of different diameters.

[0048] A valve 14 is provided between the multi-channel confluencer 11 and the second powder inlet pipe 12. The conveying volume of the second powder inlet pipe 12 is controlled by opening and closing the valve 14, so as to accurately proportion the type and particle size of the powder according to the formula.

[0049] The top center of the powder-holding cone 18 is sealed to the powder-guiding hose 19 via a connecting ring 48. The inner wall of the connecting ring 48 is fixedly connected to the upper outer periphery of the supporting vertical rod 20 via several supporting plates 49. The several supporting plates 49 are evenly distributed at equal angles. A second flow guide cap 50 is fixedly sleeved on the middle of the supporting vertical rod 20. A second stator 51 is installed in the middle of the supporting vertical rod 20 and inside the second flow guide cap 50. A second rotor 52 is installed outside the second stator 51. A second rotor 52 is fixedly sleeved on the outside of the second rotor 52. A connecting sleeve 53 is connected to the outer periphery of the connecting sleeve 53 in a sealed and rotatable manner with the inner periphery of the second guide cap 50. A flat stirring frame 54 is fixedly connected to the lower end face of the connecting sleeve 53. Several flat stirring frames 54 are provided and are evenly distributed at equal angles. The flat stirring frame 54 includes a horizontal flat rod and a vertical flat rod. Several vertical flat rods are provided and are located below the horizontal flat rods. The lower end of the vertical flat rod is adapted to the inner chamfered frustum surface of the bottom of the powder-holding cone 18, the outer side of the top of the first guide cap 21, and the outer side of the guide cylinder 26.

[0050] The inner wall of the guide cylinder 55, the inner wall of the outer connecting cylinder 28, and the inner wall of the powder outlet cylinder 30 are all fixedly connected with several rings of first needle rods 56. The outer wall of the cylindrical section of the guide cylinder 26, the outer wall of the inner connecting cylinder 27, and the outer wall of the inner powder outlet cylinder 29 are all fixedly connected with several rings of second needle rods 57. The first needle rods 56 and the second needle rods 57 in each ring are evenly distributed at equal intervals in the vertical direction. The first needle rods 56 and the second needle rods 57 in each ring are evenly distributed at equal angles. The first needle rods 56 and the second needle rods 57 in adjacent rings are evenly distributed in an alternating manner.

[0051] In this embodiment, when the powder is conveyed from the powder guiding hose 19 to the powder holding cone 18, the powder passes through the gap between adjacent support plates 49 and enters the powder holding cone 18. The second guide cap 50 ensures the powder is evenly distributed at the bottom of the powder holding cone 18. During powder loading, the guide cylinder 26 and the guide sealing ring 31 abut against the outlet of the powder holding cone 18 to seal it, facilitating powder loading. Simultaneously, the second stator 51 drives the second rotor 52, rotating the connecting sleeve 53 and causing each flat stirring frame 54 to rotate, performing flat stirring of the powder inside the powder holding cone 18, ensuring the powder is evenly distributed around the guide cylinder 26. When discharging powder, the guide cylinder 26 separates from the guide sealing ring 31, maintaining a gap. Under the influence of gravity and the top powder discharge pressure, the powder falls evenly in a ring, maintaining a uniform distribution of powder quantity across the ring surface, thus ensuring uniform powder discharge. When the guide cylinder 26 is driven by the first rotor 25 to rotate at a uniform speed, each of the second needle rods 57 rotates at a uniform speed, and the second needle rods 57 and the first needle rods 56 continuously intersect, preventing powder from accumulating between the guide cylinder 26 and the guide straight cylinder 55, between the inner connecting cylinder 27 and the outer connecting cylinder 28, and between the inner powder discharge cylinder 29 and the outer powder discharge cylinder 30. This further ensures that the powder is evenly distributed in a ring, falls evenly, and fills the gap between the mold and the mold core evenly from bottom to top, resulting in a uniform distribution of powder throughout the final cylindrical target material.

[0052] In use, the operator positions and rotates the ITO target mold using two placement racks 5. Once one rack 5 holds an ITO target mold, it is immediately pushed into the work box 1 and support box 2 via the first sliding tables on both sides, filling the ITO target mold in that rack with powder. Simultaneously, the other rack 5 is pushed out and moved to one end of the first sliding table 6, facilitating the removal of the filled ITO target mold and the placement of the replacement mold, thus shortening the rotation interval and improving filling efficiency. During filling, a vacuum pump 9 generates suction, drawing powder from the pointed-bottom barrels 4 through the second powder inlet pipes 12 and feeding it into the work box 1 through the first powder inlet pipe 10. The powder is then transferred through a multi-channel confluencer 11. The powder drawn in by each second powder inlet pipe 12 is collected and the feed rate is adjusted to make a ratio. When it is necessary to limit the particle size of the powder, it is graded and screened by the multi-layer screening mechanism 3, and the powder of each particle size is separately fed into each pointed bottom barrel 4 through each powder outlet 13. When filling, it is limited by the multi-channel confluencer 11, so that the powder within a certain particle size range is filled to optimize the target material raw material and improve the quality of the target material. The powder in the corresponding pointed bottom barrel 4 is weighed by the scale 8, and the weight of the powder filled each time is obtained by summing the weight reduction of the powder in each barrel after suction. The conveying amount of the second powder inlet pipe 12 is controlled by the opening and closing of the valve 14, so as to accurately make a ratio of the type and particle size of the powder according to the formula.

[0053] During operation, the first slide 6 accurately moves the placement rack 5 containing the mold directly below the inner powder outlet cylinder 29. Then, the second slide 17 moves the powder-holding cone 18 downwards, allowing the inner powder outlet cylinder 29 and the outer powder outlet cylinder 30 to extend into the cylindrical gap of the mold. Powder is then fed into the powder-holding cone 18 through the first powder inlet pipe 10. The powder is guided into the mold through the gaps between the guide tube 26 and the inner wall of the powder-holding cone 18, between the inner connecting tube 27 and the outer connecting tube 28, and between the inner powder outlet cylinder 29 and the outer powder outlet cylinder 30. Simultaneously, the vibrating powder mechanism 7 strikes the mold, compacting the powder. The baghouse vacuum cleaner 47 draws air from the working box 1 and the support box 2, creating negative pressure to prevent dust leakage and protect the workers. The second slide 17 continuously moves the powder-holding cone upwards. The inner powder outlet cylinder 29 is positioned so that its lower end is kept at a certain distance from the upper end of the powder accumulation. When the powder flow ends, the push rod 22 retracts, and the outer edge of the lower end of the frustum section of the guide cylinder 26 abuts against the inner edge of the guide sealing ring 31 to form a contact seal. At the same time, the vacuum pump 9 stops pumping, thereby stopping the conveying. The powder is guided by the frustum structure of the upper end of the first guide cap 21, the frustum section of the guide cylinder 26, and the inner side wall of the guide sealing ring 31, so that the powder is input into the mold in a cylindrical shape. During conveying, the first rotor 25 drives the guide cylinder 26, the inner connecting cylinder 27, and the inner powder outlet cylinder 29 to rotate together to avoid blockage during powder conveying. By replacing the inner powder outlet cylinder 29 and the outer powder outlet cylinder 30 with different sizes, and connecting them with the inner connecting cylinder 27 and the outer connecting cylinder 28 with different sizes, the size of different molds can be adapted.

[0054] During operation, the stirring motor 15 drives the scraper frame 16 to stir and rotate the powder in the pointed-bottom bucket 4, preventing powder accumulation and adhesion, and facilitating suction from the second powder inlet pipe 12. The mold is held by the various clamping vertical rods 36, and the arc-shaped structure at the upper end of the clamping vertical rods 36 facilitates mold handling and placement. During clamping, the inclined support rod 39 rotates under force, pushing each pair of limit blocks 38 in each limit groove 37 to converge, thus accommodating molds of different diameters. The elasticity of the limit springs maintains the clamping force on the clamping vertical rods 36. The mold is fully vibrated by the impact of the powder vibrating mechanism 7 while maintaining stable support through the elastic force of the limiting spring and the support spring 34. The transmission turntable 41 is rotated by the powder vibrating motor, which drives the transmission rod 42 to periodically push the positioning cylinder 44 to reciprocate. The moving resistance is reduced by the clamping roller 43. The powder vibrating hammer 46 passes through the side wall of the support box 2 and hits the side wall of the mold, thereby vibrating and compacting the powder in the mold. The position of the powder vibrating hammer 46 can be adjusted by rotating the powder vibrating screw 45 to adapt to molds of different diameters.
