Description

Technical Field

[0001] This invention relates to the field of steel ingot production, and in particular to an automatic filling equipment for encapsulated powder and its usage method. Background Technology

[0002] Steel ingot production is the process of solidifying qualified molten steel into solid steel blocks through a specific process. Among them, the cladding sintering method is an innovative process that combines powder metallurgy and hot pressing technology.

[0003] The specific procedure involves loading metal powder into a sealed casing (such as stainless steel, low-carbon steel, or ceramic sleeve), followed by vacuuming or filling with a protective gas, and then sintering under high temperature and pressure. This allows the powder particles to combine into a dense body through physicochemical processes such as diffusion and welding. Finally, the casing is removed to obtain the steel ingot. This method allows for precise control of composition and microstructure, reduces oxide inclusions, and is suitable for preparing high-purity alloy steel ingots with special properties, especially for materials such as high-nitrogen steel, which are difficult to achieve with traditional ingot casting.

[0004] The shortcomings of the above-mentioned existing technical solutions are: when the filling is close to full, due to the limited flowability of the powder, the powder near the filling port cannot be evenly diffused to the surrounding area of ​​the package in time, resulting in excessive powder accumulation in some areas and insufficient filling at the edges or corners, thus causing insufficient utilization of the internal space of the package. Summary of the Invention

[0005] This invention provides an automatic powder filling device that can solve the problem of insufficient filling at the edges or corners when the packaging is filled in the prior art, resulting in insufficient utilization of the internal space of the packaging.

[0006] An automatic powder filling device includes a conveyor base with a conveying mechanism for transporting packages. A slide rail bracket is suspended above the conveyor base, and a docking seat is slidably fitted on the slide rail bracket. A feeding pipe for docking with the package inlet is provided on the docking seat, through which powder is filled into the package. The docking seat can drive the feeding pipe to move along the slide rail bracket. A moving seat is provided inside the conveyor base, and a drive mechanism for reciprocating the moving seat is provided below the moving seat. A pushing mechanism is provided above the moving seat for pushing the package so that the package inlet docks with the feeding pipe. The drive mechanism can drive the moving seat to reciprocate, thereby driving the package placed above the pushing mechanism to reciprocate.

[0007] As a further embodiment of the present invention: the pushing mechanism includes an automatic telescopic rod fixedly disposed above the motion seat, the output end of the automatic telescopic rod is fixedly disposed with a support plate for carrying the package, and the support plate is fixedly disposed with positioning teeth for positioning the package.

[0008] As a further aspect of the present invention: a guide body is provided on the motion seat, and a sliding sleeve that slides with the guide body is provided below the support plate, the sliding sleeve being able to slide longitudinally along the guide body.

[0009] As a further aspect of the present invention: the driving mechanism includes a sliding housing, a transmission shaft rotatably mounted inside the sliding housing, a turntable coaxially fixed at the end of the transmission shaft, a drive wheel eccentrically mounted on the turntable, a connecting frame fixedly mounted below the motion seat, a drive rail fixedly mounted on the connecting frame, and a groove longitudinally provided on the drive rail to cooperate with the drive wheel; the sliding housing is provided with a driving assembly for driving the transmission shaft to rotate, and the driving assembly drives the drive wheel to perform circumferential motion through the transmission shaft and the turntable, thereby driving the drive rail to reciprocate.

[0010] As a further aspect of the present invention: the driving assembly includes a motor, a drive wheel is coaxially fixedly mounted on the output end of the motor, a transmission wheel is coaxially fixedly mounted on the transmission shaft, and a transmission belt is fitted on the drive wheel and the transmission wheel; a sliding groove is provided above the sliding box seat, and a guide plate that cooperates with both sides of the sliding groove and a roller that cooperates with the bottom of the sliding groove are fixedly mounted at the bottom of the moving seat.

[0011] As a further embodiment of the present invention: a negative pressure sleeve is sleeved on the outer side of the end of the conveying pipe, the side of the negative pressure sleeve is connected to the negative pressure pipe, and the other end of the negative pressure pipe is connected to a negative pressure device. After docking, the negative pressure sleeve and the end of the conveying pipe are inserted together into the sleeve input port.

[0012] As a further embodiment of the present invention: the conveyor seat is configured as a left and right support structure, and rail grooves are provided on both sides of the conveyor seat; the conveying mechanism includes a conveyor belt slidably disposed in the rail grooves, and a bearing seat for positioning the package is detachably disposed on the conveyor belt.

[0013] As a further aspect of the present invention: the bearing seat includes a bearing part located inside the rail groove and a limiting part for supporting the sleeve; a buckle plate for limiting the limiting part is fixedly provided above each set of rail grooves; an upper roller is rotatably provided above the limiting part; a lower roller that cooperates with the rail groove is rotatably provided below the bearing part; multiple sets of fastening blocks are evenly distributed on the conveyor belt; a positioning groove that cooperates with the fastening block is opened at the bottom of the limiting part.

[0014] As a further aspect of the present invention: a photoelectric sensor for determining the position of the carrier is fixedly installed on the conveyor seat.

[0015] A method of using an automatic powder filling device includes the following steps: S1: Start the conveyor belt, install the carrier on the conveyor belt, the conveyor belt drives the carrier into the track groove, and place the empty package on the carrier; S2: When the package moves with the carrier to above the moving seat, the conveyor belt stops moving, the pushing mechanism lifts the bottom of the package, and the upper end of the package connects with the docking seat, so that the material conveying pipe connects with the package inlet, and the powder is filled into the package through the material conveying pipe. S3: When the material conveying pipe is filled to a certain height, the drive mechanism is started, which drives the motion seat to move laterally back and forth. The motion seat drives the sleeve and docking seat placed above the pushing mechanism to move back and forth. S4: After the packaging is filled, the drive mechanism and the push mechanism are reset, and the filled packaging is transported away, completing one filling process.

[0016] The beneficial effects of this invention are: 1. In use, when the sleeve connects to the conveying pipe to begin powder filling, after the conveying pipe has been filled to a certain height, the drive mechanism drives the moving seat to reciprocate, thereby causing the sleeve and the connecting seat, placed above the pushing mechanism, to reciprocate together. During the reciprocating motion, the sleeve continues filling, and the powder sloshes inside the sleeve. This sloshing ensures that the powder at the top of the sleeve is evenly distributed, and that the powder can diffuse to the surrounding area of ​​the sleeve in a timely manner, avoiding the problem of insufficient filling in corners due to the inability of the powder to diffuse in time. This improves the utilization rate of the internal space of the sleeve and ensures filling quality.

[0017] 2. In use, the negative pressure sleeve is connected to the negative pressure pipe on one side, and the other end of the negative pressure pipe is connected to the negative pressure device. After connection, the negative pressure sleeve and the end of the conveying pipe are inserted together into the inlet of the sleeve. During the filling operation, the negative pressure device creates negative pressure in the negative pressure sleeve through the negative pressure pipe, and excess internal air is promptly extracted from the negative pressure sleeve. This prevents powder from scattering into the surrounding environment with the squeezed-out air, reducing powder waste and ensuring the health and safety of the operators.

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1 to 10 As shown in the figure, an automatic powder filling device and its usage method provided by an embodiment of the present invention include a conveyor base 1, on which a conveying mechanism 2 for transporting packages is provided. A slide rail bracket 7 is suspended above the conveyor base 1, and this slide rail bracket 7 is installed on the workshop ceiling beam or support frame. A docking seat 6 is slidably fitted on the slide rail bracket 7, such as... Figure 10 As shown, the docking seat 6 is provided with a material conveying pipe 8 for docking with the package inlet. Powder is filled into the package through the material conveying pipe 8, and the docking seat 6 can drive the material conveying pipe 8 to move along the slide rail bracket 7.

[0022] A moving seat 4 is provided inside the conveyor seat 1, and a drive mechanism 3 is provided below the moving seat 4 to drive its reciprocating motion. A pushing mechanism 5 is provided above the moving seat 4 to push the sleeve and connect the sleeve inlet with the conveying pipe 8. After the pushing mechanism 5 connects the sleeve with the conveying pipe 8, powder filling begins. After the conveying pipe 8 is filled to a certain height, the drive mechanism 3 is activated, which drives the moving seat 4 to reciprocate, thereby driving the sleeve and the docking seat 6 placed above the pushing mechanism 5 to reciprocate. During the reciprocating motion, the sleeve continues to be filled, shaking the powder inside, thus ensuring that the powder at the top of the sleeve is evenly distributed, preventing the powder from failing to spread evenly around the sleeve in time and causing insufficient filling in the corners.

[0023] Specifically, the conveyor seat 1 is configured with a left and right support structure, such as... Figure 3 As shown, the conveyor seat 1 has rail grooves 101 on both sides. The conveying mechanism 2 includes a conveyor belt 201 slidably disposed in the rail grooves 101, and a support seat 203 for positioning the package is detachably disposed on the conveyor belt 201. The support seats 203 are symmetrically distributed on the conveyor belt 201 on both sides, so as to facilitate supporting the package from both sides.

[0024] In this embodiment, the support base 203 includes a support portion 2031 located inside the rail groove 101 and a limiting portion 2032 for supporting the sleeve. Each set of rail grooves 101 is fixedly provided with a buckle plate 102 for limiting the limiting portion 2032. An upper roller 204 is rotatably disposed above the limiting portion 2032 and can slide along the bottom of the buckle plate 102. A lower roller 205, which cooperates with the rail groove 101, is rotatably disposed below the support portion 2031 and moves along the rail groove 101. In use, the sleeve is placed on the support portion 2031. At this time, the lower roller 205 presses against the rail groove 101. Simultaneously, the limiting portion 2032 tends to tilt upwards, and the upper roller 204 on the limiting portion 2032 is pressed against the buckle plate 102. During transportation, the limiting portion 2032 will fit tightly within the rail groove 101, thereby maintaining the stability of the sleeve during transport.

[0025] Multiple sets of fastening blocks 202 are evenly distributed on the conveyor belt 201, and the bottom of the limiting part 2032 has a positioning groove 206 that mates with the fastening blocks 202. In use, the support seat 203 can be placed on the fastening blocks 202 on the conveyor belt 201, so that the fastening blocks 202 and the positioning groove 206 are mutually adapted. This allows the fastening blocks 202 to drive the support seat 203 to move within the track groove 101 without being pressed out by the sleeve. Drive wheels (not shown in the figure) of the conveyor belt 201 are located at both ends of the conveyor seat 1. The movement of the conveyor belt 201 is controlled by controlling the rotation of the drive wheels.

[0026] When the package moves above the motion seat 4, a photoelectric sensor 9 for determining the position of the carrier 203 is fixedly installed on the conveyor seat 1 above the motion seat 4. Figure 3 As shown, the photoelectric sensor 9 can determine whether the carrier 203 and the sleeve have entered above the motion seat 4, thereby determining the pushing time.

[0027] like Figure 5 As shown, the pushing mechanism 5 includes an automatic telescopic rod 501 fixedly mounted above the motion seat 4. A support plate 502 for carrying the package is fixedly mounted at the output end of the automatic telescopic rod 501. Positioning teeth 503 for positioning the package are fixedly mounted on the support plate 502. In use, when the photoelectric sensor 9 is triggered, the conveyor belt 201 stops moving, the automatic telescopic rod 501 extends, causing the support plate 502 to move upwards, thereby lifting the bottom of the package. The positioning teeth 503 lock the front and rear positions of the package, ensuring that the package does not detach from the support plate 502 during reciprocating motion.

[0028] During reciprocating motion, the support plate 502 needs to overcome its own inertia and that of the sheath. To this end, a guide body 401 is provided on the motion seat 4, and a sliding sleeve 504 is provided below the support plate 502, sliding longitudinally along the guide body 401. When the automatic telescopic rod 501 extends, causing the support plate 502 to move upward, it will also cause the sliding sleeve 504 to move upward along the guide body 401, remaining fitted onto the side of the guide body 401. When the inertia of the sheath compresses the support plate 502, the support plate 502 will transmit the force received to the guide body 401 through the sliding sleeve 504, thus ensuring the stability of the support plate 502.

[0029] Furthermore, such as Figure 6 , Figure 7As shown, the drive mechanism 3 includes a sliding housing 301. A transmission shaft 304 is rotatably mounted inside the sliding housing 301. A turntable 306 is coaxially fixed at the end of the transmission shaft 304. A drive wheel 307 is eccentrically mounted on the turntable 306. A connecting frame 308 is fixedly mounted below the motion seat 4. A drive rail 309 is fixedly mounted on the connecting frame 308. The drive rail 309 has a groove longitudinally provided to cooperate with the drive wheel 307. A motor 302 is mounted on one side of the sliding housing 301. A drive wheel 303 is coaxially fixed at the output end of the motor 302. A transmission wheel 305 is coaxially fixed on the transmission shaft 304. A transmission belt is fitted onto the drive wheel 303 and the transmission wheel 305. After the motor 302 starts, it drives the drive wheel 303 to rotate. The drive wheel 303 drives the transmission wheel 305 to rotate via the transmission belt. The transmission wheel 305 drives the transmission shaft 304 to rotate. The transmission shaft 304 drives the turntable 306 to rotate. The turntable 306 drives the drive wheel 307 to perform circular motion. The drive wheel 307 pushes the drive rail 309 to move laterally and reciprocally. The drive rail 309 drives the connecting frame 308 to move laterally and reciprocally, which in turn drives the motion seat 4 to move laterally and reciprocally.

[0030] A sliding groove 310 is provided above the sliding box base 301. Guide plates 402 that mate with both sides of the sliding groove 310 and rollers 403 that mate with the bottom of the sliding groove 310 are fixedly provided at the bottom of the motion seat 4. Figure 7 As shown. When the motion seat 4 makes a lateral reciprocating motion, it will drive the guide plate 402 to move along the slide groove 310, and at the same time the roller 403 will roll at the bottom of the slide groove 310, thereby reducing the friction between the motion seat 4 and the sliding box seat 301.

[0031] During powder filling, the feed pipe 8 is inserted into the feed inlet of the sheath. During this process, air is squeezed out, carrying powder with it and contaminating the work environment. To prevent this, a negative pressure sleeve 801 is fitted onto the outer side of the feed pipe 8. The side of the negative pressure sleeve 801 is connected to a negative pressure pipe 802, and the other end of the negative pressure pipe 802 is connected to a negative pressure device. After connection, the negative pressure sleeve 801 and the end of the feed pipe 8 are inserted together into the sheath inlet. During the filling operation, excess internal air is extracted from the negative pressure sleeve 801, thus preventing powder from scattering.

[0032] Working principle: First, the conveyor belt 201 is started, moving within the track groove 101. The carrier seat 203 is placed on the fastening block 202 of the conveyor belt 201, ensuring that the fastening block 202 and the positioning groove 206 at the bottom of the limiting part 2032 of the carrier seat 203 are compatible. The carrier seat 203 moves with the conveyor belt 201. Then, an empty package is placed on the carrier seat 203. During transportation, the lower roller 205 of the carrier seat 203 presses against the track groove 101, and the limiting part 2032 tends to tilt upwards. The upper roller 204 on top is pressed against the fastening plate 102, and the limiting part 2032 fits tightly within the track groove 101, maintaining stability during package transportation.

[0033] Next, when the package moves with the carrier 203 to above the motion seat 4, the photoelectric sensor 9 fixedly installed on the conveyor seat 1 is triggered, confirming that the carrier 203 and the package have entered above the motion seat 4, and the conveyor belt 201 stops moving.

[0034] Subsequently, the automatic telescopic rod 501, fixed above the motion seat 4, extends, causing the support plate 502 to move upward and lift the bottom of the package. The positioning teeth 503 on the support plate 502 lock the front and rear positions of the package, ensuring that the package will not detach from the support plate 502 during subsequent movements. At the same time, the sliding sleeve 504 below the support plate 502 moves upward along the guide body 401 on the motion seat 4 and fits onto the side of the guide body 401, providing stable support for subsequent movements until the upper end of the package aligns with the docking seat 6, allowing the material conveying pipe 8 to align with the package input port.

[0035] Then, the powder is filled into the casing through the conveying pipe 8. At the same time, the negative pressure sleeve 801 is inserted into the casing inlet together with the end of the conveying pipe 8. The negative pressure device generates negative pressure in the negative pressure sleeve 801 through the negative pressure pipe 802. The internal air squeezed out during filling is drawn out from the position of the negative pressure sleeve 801 to prevent the powder from flying and polluting the working environment.

[0036] After the material conveying pipe 8 is filled to a certain height, the motor 302 is started. The motor 302 drives the drive wheel 303 to rotate, which in turn drives the transmission wheel 305 to rotate via a transmission belt. The transmission wheel 305 drives the transmission shaft 304 to rotate, which in turn drives the turntable 306 to rotate. The drive wheel 307 on the turntable 306 rotates in a circular motion, pushing the drive rail 309 to move laterally back and forth. The drive rail 309 drives the connecting frame 308 to move laterally back and forth, which in turn drives the moving seat 4 to move laterally back and forth. The moving seat 4 drives the sleeve and docking seat 6, which are placed above the pushing mechanism 5, to move back and forth. During the reciprocating motion, the sleeve continues to be filled, shaking the internal powder to ensure that the powder at the top of the sleeve is evenly distributed and to avoid insufficient filling in the corners. During the reciprocating motion of the motion seat 4, the guide plate 402 at the bottom of the motion seat 4 moves along the slide groove 310 above the sliding box seat 301, and the roller 403 rolls at the bottom of the slide groove 310, reducing the friction between the motion seat 4 and the sliding box seat 301.

[0037] Finally, after the packaging is filled, the powder conveying of motor 302 and conveying pipe 8 is stopped, the automatic telescopic rod 501 retracts, driving the support plate 502 and the packaging to move down, and the conveyor belt 201 continues to move, carrying away the filled packaging, thus completing one filling process.

[0038] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
