Description

Technical Field

[0001] This invention relates to the field of metal powder particle size detection technology, specifically to a novel metal powder particle size detection device. Background Technology

[0002] New material metal powders mainly include titanium alloys, stainless steel, aluminum alloys, high-temperature alloys, indium-based alloys, etc., which are widely used in aerospace, medical, electronics and other fields.

[0003] When detecting the particle size of new material metal powder, sieves with different aperture sizes are used to classify the powder. Vibration is used to separate the powder according to particle size. The mass of powder in each sieve layer is weighed and the particle size distribution is calculated. However, existing powder particle size detection devices, such as the metal powder particle size detection device disclosed in CN218271862U, include a support base, a support top plate, and a reciprocating assembly. A weighing sensor is installed at the top of the support base, and a tray is installed at the top of the weighing sensor. Two sets of adjustment mechanisms are installed at the bottom of the support base. A sliding plate is installed on one side of the top of the support top plate, and multiple sieve boxes are installed at the top of the sliding plate. A fixing mechanism is installed on the outside of the sieve boxes. The reciprocating assembly is installed on the other side of the top of the support top plate. The reciprocating assembly includes a linkage shaft, a rotating plate, two hinge rods, and a hinge plate. This utility model utilizes the design of a reciprocating component, which enables the slide to reciprocate. As the slide drives the screen box to reciprocate, the screen box sorts the metal powder into different particle sizes, and the weighing sensor obtains the weight of the metal powder of different particle sizes, thereby completing the particle size detection of the entire metal powder.

[0004] In actual use, the existing powder particle size detection devices mainly rely on vibration to achieve powder sieving. However, since the powder diameter is generally between 50μm and 10mm, the sieve mesh size is small, and the powder easily causes the sieve mesh to become clogged, thus affecting the normal sieving effect. In addition, small powder particles are prone to sticking together with large powder particles, and simple vibration cannot effectively separate them, thus affecting the accuracy of the detection data. Summary of the Invention

[0005] The purpose of this invention is to provide a novel material metal powder particle size detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a new material metal powder particle size detection device, comprising a main unit, wherein a vibration mechanism for vibrating sieving of metal powder is installed on the main unit;

[0007] The air blowing mechanism is used to disperse and prevent clogging of metal powder in the screening mechanism. The air blowing mechanism is installed in the main unit and is driven by the vibration mechanism.

[0008] A drive mechanism is used to drive the second rotating shaft to rotate, and the drive mechanism is connected to the vibration mechanism.

[0009] A screening mechanism is used to screen metal powder particles of different diameters, and the screening mechanism is mounted on a vibrating mechanism.

[0010] Preferably, the vibration mechanism includes a motor installed in the main unit, and a disc is fixed to the output end of the motor. A convex shaft is fixed on the disc, and the convex shaft is slidably connected to the fixed frame. The fixed frame is slidably connected to the main unit, and the fixed frame is fixed to the lower end face of the platform. The motor drives the disc and the convex shaft to rotate, and the sliding action between the convex shaft and the fixed frame can provide a basic force for the reciprocating motion of the platform, thereby providing a basic guarantee for the powder sieving in the sieving mechanism.

[0011] Preferably, the platform and the guide rod are slidably connected, and the guide rod is symmetrically fixed on the upper end face of the main unit. A spring is fixed between the platform and the main unit. The stability of the platform's movement can be ensured through the sliding guiding effect between the platform and the guide rod.

[0012] Preferably, a positioning ring is also fixed on the platform, and lead screws are symmetrically fixed on the upper surface of the platform. A pressure plate is slidably connected to the lead screw for pressing and limiting the screening mechanism. Through the above structure, the limiting function of the screening mechanism can be realized, ensuring the stable operation of the device.

[0013] Preferably, the blowing mechanism includes a sealing cylinder symmetrically fixed in the main unit, and a piston is slidably connected to the sealing cylinder. The end of the piston away from the sealing cylinder is fixed to the fixing frame. At the same time, a one-way air inlet valve is installed at the lower end of the sealing cylinder, and a one-way air outlet valve is installed at the upper end of the sealing cylinder. Through the above structure, one-way gas output can be realized, thereby providing a basic guarantee for the normal operation of the device.

[0014] Preferably, the drive mechanism includes a first rotating shaft connected to the platform by a bearing, and the first rotating shaft is slidably connected to the main unit. A gear is fixed on the first rotating shaft, and the gear is meshed with a toothed plate. The toothed plate is fixed inside the main unit. The first rotating shaft is connected to a one-way exhaust valve through a rotary joint and a conduit. Through the meshing transmission between the gear and the toothed plate, a basic force can be provided for the rotation of the first rotating shaft, thereby providing a basic guarantee for the rotation of the second rotating shaft.

[0015] Preferably, the screening mechanism includes a base that is nested with the positioning ring, and the base is nested with the lowest screen plate, and the screen plates are nested with each other. The screen mesh size gradually increases from bottom to top, and the uppermost screen plate is nested with the top cover. The top cover is positioned by contacting the pressure plate. With the above structure, metal powders of different particle sizes can be screened.

[0016] Preferably, the bearing on the base is connected to a connector, and the lower end of the connector is engaged with the first rotating shaft, and the upper end of the connector is engaged with the lower end of the second rotating shaft. At the same time, the bearing of the second rotating shaft is connected to the screen plate. Through the above structure, it can be ensured that the connector, the first rotating shaft and the second rotating shaft can rotate synchronously, thereby ensuring the normal operation of the device.

[0017] Preferably, a positioning rod is fixed to the lower end of the second rotating shaft, and the positioning rod and the connecting piece are nested together. A sealing ring is fixed to the outside of the positioning rod, and the sealing ring and the connecting piece are nested together to achieve a sealing effect. A gas distribution plate is also fixed on the second rotating shaft, and the through hole on the gas distribution plate is connected to the through hole in the middle of the second rotating shaft. Air outlets are evenly distributed on the gas distribution plate, and the air outlets are located below the screen on the sieve plate. Through the above structure, the stable delivery of gas can be ensured, and gas overflow can be avoided. The airflow ejected from the air outlet can also clean the screen mesh on the sieve plate, preventing the mesh from clogging. Furthermore, the airflow can blow the powder, increase the collision between the powders, and better meet the screening requirements.

[0018] Preferably, a sealing plug is also fixed on the top cover, and the sealing plug is nested with the second rotating shaft on the uppermost screen plate. The sealing plug seals the middle through hole of the second rotating shaft. Through the above structure, gas can be prevented from being discharged through the upper opening of the uppermost second rotating shaft, thereby ensuring the normal operation of the device.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This new material metal powder particle size detection device adopts a nested assembly screening mechanism, which can facilitate the disassembly and assembly of the entire device and improve the convenience of operation. With the linkage drive mechanism and air blowing mechanism, during the screening of new material metal powder, the high-speed airflow can not only realize the automatic cleaning of the mesh holes of the screen plate to avoid material blockage, but also increase the collision between the new material metal powder particles, thereby quickly removing small particles adhering to large particles, effectively increasing the screening effect and screening efficiency.

[0021] 2. This new material metal powder particle size detection device adopts a vibration mechanism, which can provide a basic force for the sieving mechanism to ensure the normal operation of sieving. The operation of the vibration mechanism can also provide a basic force for the operation of the air blowing mechanism, thereby effectively ensuring the normal operation of the device. Therefore, there is no need for an external air source. This not only simplifies the overall structure of the device, reduces the number of parts, and lowers the manufacturing cost and maintenance difficulty of the equipment, but also ensures the coordination between the sieving mechanism and the air blowing mechanism. In this way, it can effectively ensure the stability and reliability of the entire device during operation and improve the overall working efficiency of the equipment. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-8 The present invention provides a technical solution: a new material metal powder particle size detection device, including a main unit 1, on which a vibration mechanism 2 for vibrating sieving of metal powder is installed;

[0033] The blowing mechanism 3 is used to disperse and prevent blockage of metal powder in the screening mechanism 5. The blowing mechanism 3 is installed in the main unit 1 and is driven by the vibration mechanism 2.

[0034] Drive mechanism 4 is used to drive the second rotating shaft 505 to rotate. Drive mechanism 4 is connected to vibration mechanism 2.

[0035] The screening mechanism 5 is used to screen metal powder particles of different diameters. The screening mechanism 5 is installed on the vibration mechanism 2.

[0036] A positioning ring 208 is fixed on the platform 205, and lead screws 209 are symmetrically fixed on the upper surface of the platform 205. A pressure plate 210 is slidably connected to the lead screw 209 for pressing and limiting the screening mechanism 5. The screening mechanism 5 includes a base 501 nested with the positioning ring 208, and the base 501 is nested with the lowermost screen plate 502. The screen plates 502 are nested with each other, and the mesh size of the screen plates 502 gradually increases from bottom to top. The uppermost screen plate 502 is nested with the top cover 503, and the top cover 503 contacts the pressure plate 210 for positioning. A connecting piece 504 is connected to the base 501 by a bearing. The lower end of the connecting piece 504 is engaged with the first rotating shaft 401, and the upper end of the connecting piece 504 is engaged with the lower end of the second rotating shaft 505. The rotating shaft 505 is bearing connected to the screen plate 502; a positioning rod 506 is fixed at the lower end of the second rotating shaft 505, and the positioning rod 506 and the connecting piece 504 are nested together, and a sealing ring 507 is fixed on the outside of the positioning rod 506. The sealing ring 507 and the connecting piece 504 are nested together to achieve a sealing effect. A gas distribution plate 508 is also fixed on the second rotating shaft 505, and the through hole on the gas distribution plate 508 is connected to the middle through hole of the second rotating shaft 505. Air outlets 509 are evenly opened on the gas distribution plate 508, and the air outlets 509 are located below the screen on the screen plate 502; a sealing plug 510 is also fixed on the top cover 503, and the sealing plug 510 is nested together with the second rotating shaft 505 on the uppermost screen plate 502. The sealing plug 510 seals the middle through hole of the second rotating shaft 505.

[0037] When using this new material metal powder particle size detection device, such as Figures 1-8As shown, the screening mechanism 5 is first installed on the platform 205. The base 501 is fixed in place by nesting with the positioning ring 208. During installation, the connecting piece 504 and the first rotating shaft 401 engage to form an integral structure, with the through hole in the connecting piece 504 communicating with the through hole in the first rotating shaft 401, providing a foundation for subsequent gas transport. After the base 501 is installed, the following steps are performed: A screen plate 502 with suitable screen holes is installed, and the screen hole diameter gradually increases from bottom to top. When assembling the screen plate 502 onto the base 501, installation is achieved by nesting the base 501 with the screen plate 502. Furthermore, by nesting the lower end of the second rotating shaft 505 with the connecting piece 504, the second rotating shaft 505 and the connecting piece 504 form an integrated structure, providing a foundation for the subsequent rotation of the second rotating shaft 505. During the nested installation of the second rotating shaft 505 and the connecting piece 504, the positioning rod 506 and the connecting piece... The nesting between the connectors 504 and the sealing effect between the sealing ring 507 and the connector 504 ensure the airtightness of the connection and prevent gas leakage. When assembling multiple screens 502, installation is achieved by nesting the upper screen 502 with the lower screen 502. Furthermore, nesting the upper second rotating shaft 505 with the lower second rotating shaft 505 completes the assembly of the two second rotating shafts 505. The positioning rod 506 on the upper second rotating shaft 505 is nested with the lower second rotating shaft 505. With the sealing ring 507, the integrity and sealing of the connection of multiple second rotating shafts 505 can be guaranteed. Then, a certain amount of new material metal powder (such as 200 grams) is placed in the uppermost sieve plate 502. Finally, the top cover 503 is nested with the uppermost sieve plate 502 to achieve positioning. The through hole on the uppermost second rotating shaft 505 is sealed by the sealing plug 510 to complete the assembly of the device. Then, the pressure plate 210 is inserted through the screw 209 and contacts the top cover 503. The nut is used to lock it to complete the assembly of the device.

[0038] The vibration mechanism 2 includes a motor 201 installed inside the main unit 1, with a disk 202 fixed to the output end of the motor 201. A convex shaft 203 is fixed to the disk 202, and the convex shaft 203 is slidably connected to the fixing frame 204. The fixing frame 204 is slidably connected to the main unit 1 and is fixed to the lower end face of the platform 205. The platform 205 is slidably connected to the guide rod 206, and the guide rod 206 is symmetrically fixed to the upper end face of the main unit 1. A spring 207 is fixed between the platform 205 and the main unit 1. The air blowing mechanism 3 includes a sealing cylinder 301 symmetrically fixed to the front and rear of the main unit 1, and a sliding connection is provided on the sealing cylinder 301. A piston 302 is connected, and the end of the piston 302 away from the sealing cylinder 301 is fixed to the fixed frame 204. At the same time, a one-way air inlet valve 303 is installed at the lower end of the sealing cylinder 301, and a one-way air outlet valve 304 is installed at the upper end of the sealing cylinder 301. The drive mechanism 4 includes a first rotating shaft 401 connected to the platform 205 by a bearing. The first rotating shaft 401 is slidably connected to the main unit 1. A gear 402 is fixed on the first rotating shaft 401. At the same time, the gear 402 is meshed with the toothed plate 403. The toothed plate 403 is fixed inside the main unit 1. The first rotating shaft 401 is connected to the one-way air outlet valve 304 through a rotary joint and a conduit.

[0039] After the device is assembled, such as Figures 1-8As shown, the motor 201 is started, which drives the disc 202 and the cam shaft 203 to rotate. Combined with the sliding action between the cam shaft 203 and the fixed frame 204, the platform 205 and the screening mechanism 5 vibrate back and forth in an orderly manner. This allows the screen disc 502 to screen the new material metal powder, thereby classifying different new material metal powder particles. Simultaneously, as the fixed frame 204 moves back and forth in an orderly manner, it drives the piston 302 to move. Through the sliding action between the piston 302 and the sealing cylinder 301, the sealing cylinder 301 can be vented, allowing the gas inside the sealing cylinder 301 to be output in one direction. The output gas enters the gas distribution plate 508 through the through holes on the first rotating shaft 401, the connecting piece 504, and the second rotating shaft 505, and is ejected outward through the gas outlet 509 on the gas distribution plate 508. Since the gas outlet 509 is located below the screen on the screen disc 502, the gas is released through the gas outlet 509. The high-speed airflow ejected from the screen 502 can blow away the powder particles that clog the mesh openings, thus preventing particle blockage from affecting the normal screening process. Under the action of the high-speed airflow, the material on the screen 502 can be blown agitated, allowing the powder particles to collide with each other. Through the collision of powder particles, small particles adhering to the surface of large particles can be detached, further ensuring the separation quality of the material. When the platform 205 moves, it synchronously drives the first rotating shaft 401 and gear 402 to move. With the meshing transmission between gear 402 and toothed plate 403, the first rotating shaft 401 can rotate in both directions in an orderly manner, thereby driving the connecting piece 504, the second rotating shaft 505 and the air distribution plate 508 to rotate. By rotating the air distribution plate 508, the position of the airflow blown from the air outlet 509 can be adjusted to achieve a comprehensive unclogging effect on the mesh openings of the screen 502, thereby ensuring the normal operation of the device.

[0040] After the material screening is completed, the screening mechanism 5 is disassembled according to the above principle, and the particle size distribution of the new material metal powder is determined by weighing the powder particles carried in the multiple screen plates 502 and the base 501.
