Abstract
Description
Technical Field
[0001] This invention relates to the field of feeding devices for tungsten powder preparation, and in particular to a fully automatic auxiliary feeding device for tungsten powder preparation. Background Technology
[0002] In industrial applications, tungsten trioxide is generally used as the raw material for tungsten powder preparation. The mainstream method is hydrogen reduction (yellow tungsten process), which usually involves two-stage reduction. There are also one-stage reduction and carbon reduction processes. However, regardless of the reduction process, it is generally necessary to quantitatively feed the tungsten trioxide raw material into the reaction boat, and then send the reaction boat into a tube furnace for high-level reduction.
[0003] However, existing methods for feeding tungsten trioxide raw materials into the reaction vessel typically involve weighing them quantitatively and then directly pouring them into the vessel. A scraper is then used to spread the tungsten trioxide evenly within the vessel, ensuring uniform reduction in the tube furnace. However, this direct pouring method easily leads to tungsten trioxide agglomeration, making subsequent leveling and spreading cumbersome. Furthermore, the manual weighing and spreading process is often inefficient, resulting in slow raw material feeding and low automation in tungsten powder preparation. Therefore, a fully automated auxiliary feeding device for tungsten powder preparation is proposed. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies, this invention proposes a fully automatic auxiliary feeding device for tungsten powder preparation, which solves the problems of low automation, inconvenience in uniform spreading, and inefficient feeding of tungsten trioxide auxiliary feeding equipment in the preparation of tungsten powder.
[0005] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows: A fully automatic auxiliary feeding device for preparing tungsten powder includes a base, a tray fitted inside the base, and multiple springs arranged in a circular array connecting the lower end of the tray to the upper end of the base. Telescopic components are installed on both radial sides of the tray, and a feeding cylinder is connected to the upper output end of the telescopic components on both sides.

[0011] Preferably, the swing assembly includes a sliding frame, a slider, a limiting sleeve, and a limiting rod. The sliding frame is connected to the front side of the mounting base. The slider is slidably fitted inside the sliding frame. The limiting sleeve is embedded in the slider and extends through the upper and lower ends of the slider. The lower end of the limiting rod is slidably fitted inside the limiting sleeve and is connected to the upper inner wall of the limiting sleeve by a spring. The lower end of the limiting rod slides through the lower end of the limiting sleeve and extends below it. The lower extension end of the limiting rod is fitted into the sleeve. The tray is connected to a bracket, the abutment frame is connected to the bracket, the front end of the bracket is connected to a guide rod frame, and a sleeve seat is slidably sleeved on the outside of the guide rod frame, and the slide seat is connected to the upper end of the sleeve seat.
[0012] Preferably, the upper and lower ends of the sliding frame are connected through, and guide rod frames are connected to both sides of the sliding frame.

[0013] Preferably, the drive assembly includes a servo motor and a turntable. The servo motor is mounted on the tray, and the turntable is coaxially fitted on the upper output end of the servo motor.

[0015] The beneficial effects of this invention are: 1. The technical solution of this invention uses an automated weighing device to quantitatively weigh tungsten trioxide raw materials and automatically transfers them into a feeding cylinder. A conveying device is installed at the bottom of the base for cyclically conveying the reaction boat. The conveying device is controlled to operate slowly but continuously. When the conveying device conveys the front end of the reaction boat to below the feeding hopper, the telescopic component is controlled to retract, causing the connecting plate and the feeding cylinder to move downwards. This allows the rack frame to follow and move downwards, contacting the contact frame. Consequently, the rack frame slides upwards relative to gear one on the slide bar frame, compressing spring two. During this process, the rack frame and... The meshing of gear one drives the rotating shaft to rotate downwards, which in turn causes the spreading hopper to rotate downwards towards the feeding cylinder, thus removing the blockage at the lower end of the feeding cylinder. At the same time, the spreading hopper will also rotate to an inclined state. Under the action of gravity, the rated amount of tungsten trioxide raw material weighed in the feeding cylinder will be spread onto the reaction vessel of the conveying equipment through the spreading hopper. As the reaction vessel is slowly conveyed, it is gradually spread onto the reaction vessel from right to front to back front, realizing automated feeding into the reaction vessel. The feeding and spreading are relatively uniform, which facilitates the rapid spreading of tungsten trioxide raw material in the reaction vessel and can improve feeding efficiency.
[0016] 2. The technical solution of this invention involves the telescopic component contracting to cause the rack frame to contact the contact frame and continuously move downwards. During this process, the feeding cylinder and its mounting base will move downwards accordingly. Consequently, the sliding frame and slider on the mounting base will also move downwards. The downward movement of the slider can cause the limiting rod slidably fitted in the inner limiting sleeve to move downwards and gradually be inserted into the insert on the sliding block. Then, the servo motor is controlled to run, driving the turntable to rotate. This causes the turntable to push the sliding block to slide back and forth along the guide rod frame, indirectly causing the limiting rod to slide along with it. This allows the limiting sleeve and slider to slide within the sliding frame, and causes the sliding frame and mounting base to swing horizontally around the pin shaft. As the spreading hopper gradually tilts downwards at this time, the blockage at the lower end of the feeding cylinder is removed. This allows the spreading hopper to swing horizontally while tilting and spreading the tungsten trioxide raw material in the feeding cylinder into the reaction vessel, further improving the uniformity of spreading the tungsten trioxide raw material in the reaction vessel, facilitating subsequent efficient spreading, and improving feeding efficiency.
[0017] 3. The technical solution of this invention uses the operation of a servo motor to drive the turntable to rotate, which in turn drives the second gear to rotate. The meshing of the second gear with the gear ring will drive the gear ring and the turntable to rotate. As a result, the multiple top plates connected to the lower end of the turntable will engage with the multiple top balls connected to the upper end of the base, causing the tray and its structure to vibrate relative to the base. This allows the feeding cylinder and the feeding hopper to vibrate while the tungsten trioxide raw material in the feeding cylinder is evenly spread onto the reaction vessel by the feeding hopper. This prevents the tungsten trioxide raw material from remaining on it, improves the accuracy of the feeding quality, and also improves the precision of the subsequent tungsten powder preparation process by reducing tungsten trioxide.

[0020] The following will be combined with the appendix Figure 1 To be continued Figure 10 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0021] Example 1:
[0022] like Figures 1-10 As shown, this invention discloses a fully automatic auxiliary feeding device for preparing tungsten powder, including a base 2, a tray 4 is fitted inside the base 2, and multiple springs 3 are circumferentially connected to the lower end of the tray 4 and the upper end of the base 2. Telescopic members 5 are installed on both radial sides of the tray 4, and a feeding cylinder 7 is connected to the upper output end of the telescopic members 5 on both sides. A pin seat 8 is connected to the front side of the feeding cylinder 7, and a pin 9 is rotatably fitted inside the pin seat 8. A fitting seat 10 is connected to the lower end of the pin 9, and a rotating shaft 11 is rotatably fitted through the fitting seat 10. A spreading hopper 12 that cooperates with and seals the lower end of the feeding cylinder 7 is connected to the tray 4. An abutment frame 20 is connected to the fitting seat 10. An opening and closing component is provided on the fitting seat 10. The opening and closing component is used to cooperate with the abutment frame 20 to abut when the feeding cylinder 7 moves down, and drive the rotating shaft 11 and the spreading hopper 12 to rotate downward about the rotating shaft 11 as the center, and open the bottom of the feeding cylinder 7. A slide block 27 is slidably mounted on the front side of the tray 4. An insert 28 is rotatably fitted on the upper surface of the slide block 27. A swing component is also provided on the mounting base 10. The swing component is used to engage with the insert 28 when the feeding cylinder 7 moves down and the spreading hopper 12 rotates downward around the pivot 11, and drives the mounting base 10 to swing back and forth around the pivot 9. A drive component is provided on the tray 4. The drive component is used to drive the slide block 27 to slide back and forth on the tray 4 in front of the mounting base 10. A rotating ring 43 is rotatably mounted on the tray 4. A vibration component is provided on the rotating ring 43. The vibration component is used to drive the tray 4 and the feeding cylinder 7 and spreading hopper 12 to vibrate relative to the base 2 when the slide block 27 is driven to slide back and forth. This is to ensure complete feeding of the tungsten trioxide powder in the feeding cylinder 7 and spreading hopper 12 by vibrating them during feeding.
[0023] The feeding cylinder 7 is a cylindrical structure with a smooth inner wall, and the inner wall of the spreading hopper 12 is also smooth to avoid residue of tungsten trioxide raw material on the inner walls of both during feeding. A high-precision quantitative weighing device is installed above the feeding cylinder 7 to quantitatively weigh the tungsten trioxide raw material and feed it into the feeding cylinder 7. The feeding cylinder 7 is sealed at its lower end by the spreading hopper 12 to carry the quantitatively weighed tungsten trioxide raw material. An existing conveying device is installed below the base 2 to circulate and transport the reaction boat that can be heated in the tube furnace. The conveying device is set to a slow operating speed but runs continuously, so that when the front end of the reaction boat is conveyed to the spreading hopper 12, the feeding operation can be carried out into the reaction boat.
[0024] The base 2 is radially symmetrically mounted with mounting brackets 1 on both sides, and multiple bolt holes are arrayed on the mounting brackets 1 on both sides. The output ends of the telescopic parts 5 on both sides are connected to connecting plates 6. The connecting plates 6 on both sides are arranged radially along the feeding cylinder 7, and the connecting plates 6 on both sides are close to each other and connected to the two sides of the feeding cylinder 7 respectively.
[0025] The mounting bracket 1 facilitates the stable installation of this device on existing conveying equipment and other related equipment for combined use.
[0026] The base 2 is symmetrically equipped with parallel electric slide rails 46 on both sides. A slide frame 47 is slidably arranged between the two electric slide rails 46 and perpendicular to them. A push rod motor 48 is embedded at both ends of the slide frame 47. The lower output end of the push rod motor 48 on both sides extends to the bottom of the slide frame 47 and is connected to a scraper 49 at the extended end to further scrape the tungsten trioxide powder spread in the reaction boat.
[0027] An industrial vision system is also installed on one side of the base 2. This system includes an industrial camera and an image processing unit, with the camera facing the reaction boat below the hopper 12. After the hopper 12 spreads tungsten trioxide raw material into the reaction boat, the industrial vision system acquires images of the spread material in real time and analyzes the uniformity of the powder distribution and the coverage boundary within the reaction boat through the image processing unit. If abnormalities such as local accumulation, material shortage, or spreading deviation are detected, the industrial vision system sends a feedback signal to the control system. Based on the feedback results, the control system selectively controls the telescopic component 5 and the drive assembly to coordinate their movements, allowing the hopper 12 to adjust its swing amplitude and feeding angle during subsequent feeding, achieving closed-loop control; or it controls the electric slide rail 46 and the push rod motor 48 to drive the scraper 49 to perform point-by-point leveling of the spread area. By introducing industrial vision, automatic detection and dynamic adjustment of the spreading quality are achieved, further improving the automation level and consistency of raw material conveying and spreading during tungsten powder preparation.
[0028] The scraper 49 is driven by the electric slide rail 46. When the material spreading in the hopper 12 is insufficient, the push rod motor 48 can be controlled to move the scraper 49 into the reaction vessel as it passes under the scraper 49. The scraper 49 is then further spread and leveled by the relative displacement with the reaction vessel. If it is still not level enough, the electric slide rail 46 can be controlled to move the carriage 47 back and forth quickly along the conveying direction to further spread and level the tungsten trioxide material in the reaction vessel. This achieves fully automated operation, efficiently and quickly transporting the tungsten trioxide material into the reaction vessel and spreading it to the required level. The scraper 49 also increases the redundancy of the leveling. When the spreading in the hopper 12 is insufficient, the scraper 49 can be used for further spreading.
[0029] Example 2:
[0030] like Figures 1-10 As shown, the present invention discloses an inductance testing machine for circuit board inductance components. Compared with Embodiment 1, this embodiment discloses the structure of the opening and closing assembly.
[0031] The opening and closing assembly includes a gear 13, a slide bar frame 15, a sleeve 16, and a rack frame 18. The gear 13 is arranged on both sides and is fitted onto the extension ends of the rotating shaft 11 on both outer sides of the sleeve 10. The slide bar frame 15 is connected to the sleeve 10. The sleeve 16 is slidably fitted onto the outer side of the slide bar frame 15, and a spring 17 fitted onto the outer side of the slide bar frame 15 is connected between the upper end of the sleeve 16 and the upper end of the slide bar frame 15. The rack frame 18 is connected to the sleeve 16, and the two sides of the rack frame 18 mesh with the sides of the gear 13 away from the feeding cylinder 7. The lower end of the rack frame 18 abuts against the upper surface of the contact frame 20.
[0032] The retraction of the telescopic component 5 causes the connecting plate 6 and the feeding cylinder 7 to move downwards, which in turn causes the rack frame 18 to move downwards and come into contact with the contact frame 20. The rack frame 18 then slides upwards on the slide rod frame 15 relative to the gear 13, compressing the spring 17. During this process, the meshing of the rack frame 18 and the gear 13 drives the rotating shaft 11 to rotate downwards, causing the spreading hopper 12 to rotate downwards towards the feeding cylinder 7, thus removing the blockage at the lower end of the feeding cylinder 7. At the same time, the spreading hopper 12 will also rotate to an inclined state. Under the action of gravity, the rated amount of tungsten trioxide raw material weighed in the feeding cylinder 7 will be spread onto the reaction vessel of the conveying equipment through the spreading hopper 12. As the reaction vessel is slowly conveyed, it is gradually spread from right to front to back front onto the reaction vessel, realizing automated feeding into the reaction vessel. The feeding and spreading are relatively uniform, which facilitates the rapid spreading of tungsten trioxide raw material in the reaction vessel and can improve the feeding efficiency.
[0033] The front side of the set base 10 away from the feed cylinder 7 is connected to the support plate 14, and the slide rod frame 15 is connected to the support plate 14. The front side of the feed cylinder 7 is connected to the pin seat 21, and the front end of the pin seat 21 is rotatably connected to the abutment plate 22. The two sides of the feed cylinder 7 are also connected to the connecting seats 23. The two sides of the connecting seats 23 are connected to the two ends of the abutment plate 22, and the front side of the abutment plate 22 is in contact with the rear side of the support plate 14. The two sides of the feed cylinder 7 are also connected to the top frame 50, which is in contact with the two sides of the rack frame 18.
[0034] The engagement of the support plate 14 and the abutment plate 22, as well as the engagement of the top frame 50 and the rack frame 18, ensures that when the rack frame 18 is not in contact with the abutment frame 20, the feeding hopper 12 is in a horizontal position. Furthermore, the elastic force of the spring 17 is sufficient to maintain the horizontal position of the feeding hopper 12 even when the tungsten trioxide material in the feeding cylinder 7 is fully loaded, thus sealing the lower end of the feeding cylinder 7. In this state, the feeding hopper 12 will not easily rotate around the pivot 11, and the rack frame 18, due to its engagement with the top frame 50, will not allow the mounting base 10 to easily swing horizontally around the pin 9. When the rack frame 18 is not in contact with the abutment frame 20... When the top frame 50 moves upward relative to the top frame 50, the top frame 50 cancels the horizontal contact with the rack frame 18, and the abutment plate 22 can exert a certain force on the support plate 14 under the action of the springs 24 on both sides, ensuring that the mounting base 10 is relatively stable. When the limiting rod 35 is inserted into the insert 28, the mounting base 10 can rotate back and forth under the action of external force, and simultaneously stretch the springs 24 on one side and compress the springs 24 on the other side, so that the mounting base 10 is stable when the material hopper 12 is sealing, and will not swing easily, ensuring that the material hopper 12 seals the bottom of the feeding cylinder 7 tightly.
[0035] Example 3:
[0036] like Figures 1-10 As shown, the present invention discloses an inductance testing machine for circuit board inductance components. Compared with Embodiment 2, this embodiment discloses the structure of the swing assembly.
[0037] The swing assembly includes a sliding frame 29, a slider 30, a limiting sleeve 34, and a limiting rod 35. The sliding frame 29 is connected to the front side of the mounting base 10. The slider 30 is slidably fitted inside the sliding frame 29. The limiting sleeve 34 is embedded inside the slider 30 and extends through the upper and lower ends of the slider 30. The lower end of the limiting rod 35 is slidably fitted inside the limiting sleeve 34, and a spring 36 is connected between the limiting rod 35 and the upper inner wall of the limiting sleeve 34. The lower end of the limiting rod 35 slides through the lower end of the limiting sleeve 34 and extends below it. The lower extension end of the limiting rod 35 is fitted into the insert 28.
[0038] As the telescopic component 5 retracts, causing the rack frame 18 to contact the contact frame 20 and continuously move downwards, the feeding cylinder 7 and its mounting base 10 will move downwards accordingly. Consequently, the sliding frame 29 and the slider 30 on the mounting base 10 will also move downwards. The downward movement of the slider 30 can cause the limiting rod 35, which is slidably fitted in the inner limiting sleeve 34, to move downwards and gradually be inserted into the insert 28 on the slide block 27. Then, when the drive component drives the slide block 27 to slide back and forth, it can indirectly drive the limiting rod 35 to slide along with it. This allows the limiting sleeve 34 and the slider 30 to slide within the sliding frame 29, and drives the sliding frame 29 and the mounting base 10 to swing horizontally around the pin 9. As the spreading hopper 12 gradually tilts downwards at this time, the blockage at the lower end of the feeding cylinder 7 is removed, allowing the spreading hopper 12 to swing horizontally while spreading the tungsten trioxide raw material in the feeding cylinder 7 into the reaction vessel. This further improves the uniformity of spreading the tungsten trioxide raw material in the reaction vessel, facilitates efficient subsequent spreading, and improves feeding efficiency.
[0039] A bracket 19 is connected to the tray 4, and an abutment frame 20 is connected to the bracket 19. A guide rod frame 25 is connected to the front end of the bracket 19, and a sleeve 26 is slidably sleeved on the outside of the guide rod frame 25. A slide 27 is connected to the upper end of the sleeve 26, which ensures the stability of the slide 27 reciprocating.
[0040] The upper and lower ends of the slide frame 29 are connected, and guide rod frames 21 are connected to both sides of the slide frame 29. Sleeve blocks 32 are connected to both sides of the slider 30 and are slidably sleeved on the outside of the guide rod frames 21. Each sleeve block 32 is connected to the front end of the guide rod frame 21 and is sleeved on the outside of the guide rod frame 21. This ensures the stability of the slider 30 sliding in the slide frame 29. Without external force, the spring 5 33 will push the slider 30 to slide close to the feeding cylinder 7 and return to the state of contact with the inner wall of the slide frame 29.
[0041] Example 4:
[0042] like Figures 1-10 As shown, the present invention discloses an inductor testing machine for circuit board inductor components. Compared with Embodiment 3, this embodiment discloses the structure of the driving component.
[0043] The drive components include a servo motor 37 and a turntable 38. The servo motor 37 is mounted on the tray 4, and the turntable 38 is coaxially mounted on the upper output end of the servo motor 37. A rotating plate 39 is rotatably connected between the outer edge of the upper surface of the tray 4 and the slide 27.
[0044] By controlling the servo motor 37 to run, driving the turntable 38 to rotate, the slide block 27 can be pulled back and forth on the guide rod frame 25 via the rotating plate 39.
[0045] Example 5:
[0046] like Figures 1-10 As shown, the present invention discloses an inductance testing machine for circuit board inductance components. Compared with Embodiment 4, this embodiment discloses the structure of the vibration assembly.
[0047] The vibration assembly includes a second gear 40, a frame 41, a gear ring 42, a top plate 44, and top beads 45. The second gear 40 is coaxially mounted on the lower end of the turntable 38, the frame 41 is coaxially mounted on the upper end of the tray 4, the gear ring 42 is rotatably mounted on the upper end of the frame 41, the rotating ring 43 is mounted on the outer side of the gear ring 42, the top plate 44 is arrayed and connected to the lower end face of the rotating ring 43, and the top beads 45 are circumferentially arrayed and connected to the upper end face of the base 2, and cooperate with and abut against the lower end of the top plate 44.
[0048] The operation of the servo motor 37 drives the turntable 38 to rotate, and also drives the gear 40 to rotate. The meshing of the gear 40 and the gear ring 42 will drive the gear ring 42 and the rotating ring 43 to rotate. In turn, the multiple top plates 44 connected to the lower end of the rotating ring 43 will cooperate and abut against the multiple top beads 45 connected to the upper end of the base 2, causing the tray 4 and its structure to vibrate relative to the base 2. This allows the feeding cylinder 7 and the feeding hopper 12 to vibrate while the tungsten trioxide raw material in the feeding cylinder 7 is evenly spread on the reaction vessel by the spreading hopper 12. This prevents the tungsten trioxide raw material from accumulating on it, improves the accuracy of the feeding quality, and also improves the precision of the subsequent tungsten powder preparation process by reducing tungsten trioxide.
