[0066] 1. The present invention provides an automatic loading system for a vacuum melting furnace. A conveying mechanism transports a feeding bucket to a lifting mechanism, which automatically lifts the feeding bucket. A gripping mechanism then directly grabs the feeding bucket and places it on a feeding mechanism. The feeding mechanism then transfers the feeding bucket into the feeding mechanism, achieving automatic conveying, lifting, and precise spatial movement of the bucket without manual intervention, significantly reducing labor intensity and improving loading efficiency. Furthermore, the automatic loading system for a vacuum melting furnace, through the coordinated operation of the conveying mechanism, lifting mechanism, gripping mechanism, and feeding mechanism, can more precisely control the loading speed of the feeding bucket, ensuring consistency in each loading, thereby maintaining the melting efficiency of the vacuum melting furnace.

[0067] 2. The utility model provides an automatic feeding system for a vacuum melting furnace, in which the connection between the conveying mechanism and the lifting mechanism can be disassembled. When the feeding bucket needs to be fed, the conveying mechanism and the lifting mechanism are connected. After the feeding bucket is fed, the conveying mechanism can be disassembled, thereby reducing the space occupancy rate.

[0068] 3. The utility model provides an automatic loading system for a vacuum melting furnace. The first conveying structure not only rises and falls along the frame driven by the lifting structure, but the first conveying structure can also convey the feeding barrel thereon, so that the feeding barrel can be quickly conveyed to the next link after the lifting is completed, thereby realizing the automatic lifting and automatic transmission of the feeding barrel.

[0069] 4. This utility model provides an automatic loading system for a vacuum melting furnace. When the first conveying structure rises to a specified height, the first conveying structure operates, transferring the charging bucket on it to the second conveying structure, which then transports the charging bucket. The first and second conveying structures in this utility model ensure stable and continuous transfer of the charging bucket.

[0070] 5. This utility model provides an automatic charging system for a vacuum melting furnace. Through the coordinated operation of a charging barrel, an automatic charging system for the vacuum melting furnace, a feeding mechanism, and a charging mechanism, this system enables automated loading of the charging barrel and automatic discharge of the material after discharge, eliminating the need for human intervention and significantly improving production efficiency. Furthermore, this system enables precise control and rapid addition of raw materials, while avoiding complex structures and high manufacturing costs, thereby improving melting efficiency and quality.

[0071] 6. The utility model provides an automatic feeding system for a vacuum melting furnace. Since the barrel support plate and the feeding barrel are fixed by a clamping method, it is not easy for the feeding barrel to fall off accidentally during the transportation process, thereby ensuring the stability of the feeding barrel during transportation. Because the barrel support plate of the utility model can hold up the clamping part on the feeding barrel, and by using a combination of slide rails and sliders, it can ensure that the movement trajectory of the feeding barrel during the ascent or descent process is more precise and stable. Compared with the hoisting method, the utility model can avoid the problem of shaking of the feeding barrel during the lifting process. The entire feeding barrel loading and withdrawal process can be automatically completed by the feed sliding plate and the feeding guide drive structure without manual intervention, which reduces labor intensity and speeds up the production rhythm.

[0072] 7. This utility model provides an automatic charging system for a vacuum melting furnace. The clamping portion is provided with a snap-in interface. The top of the barrel support plate is provided with a snap-in protrusion that engages with the snap-in interface. This provides a more stable connection between the barrel support plate and the charging barrel, ensuring that the charging barrel is securely positioned on the barrel support plate, reducing safety risks caused by loosening or slipping during the transfer of the charging barrel. The snap-in structure allows for precise positioning of the charging barrel, ensuring its positional accuracy during ascent and descent, thereby improving the operational accuracy of the entire system.

The automatic loading system for a vacuum melting furnace of the present invention is only a preferred embodiment and does not limit the scope of protection of the automatic loading system for a vacuum melting furnace.

[0092] A vacuum melting furnace is a complete set of vacuum smelting equipment that uses medium-frequency induction heating to melt metal under vacuum conditions. It is an important refining and smelting equipment used to produce special alloy materials such as nickel-based high-temperature alloys, precision alloys, stainless steel, and ultra-high-strength steel. Vacuum melting furnaces can be divided into master alloy melting furnaces and deformed alloy melting furnaces based on the type of material being melted; based on the type of furnace, vacuum melting furnaces can be divided into periodic furnaces and semi-continuous furnaces. The upper charging device of a vacuum melting furnace is a key component of the vacuum melting furnace. The charging mechanism in the upper charging device of the vacuum melting furnace is connected to the feed port of the vacuum melting furnace. When charging the charging mechanism, the charging barrel needs to be transferred into the charging mechanism.

[0093] Currently, traditional feeding processes mostly require manual assistance. There are also some semi-automated feeding devices on the market that use cranes and hooks to transport and lift the feeding barrels. However, this equipment requires a lot of staff participation, is labor-intensive, and has relatively low efficiency.

[0094] Based on this, the utility model provides an automatic feeding system for a vacuum melting furnace, which realizes automatic feeding of the feeding barrel through the coordinated work of a conveying mechanism, a lifting mechanism, a grabbing mechanism and a feeding mechanism, thereby reducing the intensity of manual labor.

[0095] Example 1

[0096] The specific embodiments of the present invention will be described in detail below in conjunction with the automatic feeding system for a vacuum melting furnace according to the first aspect of the present invention.

[0097] It should be noted that the automatic loading system for a vacuum melting furnace in the first aspect of the present invention is only a preferred embodiment of the present invention. The automatic loading system for a vacuum melting furnace in the present invention can adopt the automatic loading system for a vacuum melting furnace in the first aspect of the present invention, or can adopt other structures. For the convenience of explanation, the automatic loading system for a vacuum melting furnace in the first aspect of the present invention will be described in detail below.

[0098] Combine Figures 1 to 6 As shown, this embodiment discloses an automatic feeding system for a vacuum melting furnace, comprising a conveying mechanism 2 , a lifting mechanism 3 , a gripping mechanism 4 and a feeding mechanism 5 .

[0099] The conveying mechanism 2 is used to convey the feeding bucket 1 along a specified direction. The feeding bucket 1 is used to load raw materials.

[0100] The lifting mechanism 3 is arranged across one side of the conveying mechanism 2. When the feeding bucket 1 is loaded, the lifting mechanism 3 is connected with the discharge end of the conveying mechanism 2 and receives the feeding bucket 1 transmitted by the conveying mechanism 2, and then the lifting mechanism 3 lifts the feeding bucket 1 to a specified height so that the feeding bucket 1 can be sent to the grabbing mechanism 4.

[0101] The grabbing mechanism 4 is arranged on one side of the lifting mechanism 3. When the charging bucket 1 is loaded, the grabbing mechanism 4 grabs the charging bucket 1 on the lifting mechanism 3 and places it on the feeding mechanism 5.

[0102] The feeding mechanism 5 is used to transfer the feeding bucket 1 to the feeding mechanism 6 connected to the feeding port of the vacuum melting furnace.

[0103] The automatic loading system for the vacuum melting furnace described above conveys the feeding bucket 1 to the lifting mechanism 3 via the conveying mechanism 2, automatically lifting the feeding bucket 1 via the lifting mechanism 3, and then directly grabbing the feeding bucket 1 and placing it on the feeding mechanism 5 via the grabbing mechanism 4. The feeding mechanism 5 then transfers the feeding bucket 1 into the feeding mechanism 5, enabling fully automated loading of the feeding bucket 1 without manual intervention, greatly reducing labor intensity and improving loading efficiency. Furthermore, the automatic loading system for the vacuum melting furnace described above, through the coordinated operation of the conveying mechanism 2, the lifting mechanism 3, the grabbing mechanism 4, and the feeding mechanism 5, can more accurately control the loading speed of the feeding bucket, ensuring consistency in each loading, thereby guaranteeing the melting efficiency of the vacuum melting furnace.

The first conveying structure 34 is arranged on the guide structure 32 and rises and falls synchronously with the guide structure 32. When the feeding bucket 1 is loaded, the lifting structure 33 drives the first conveying structure 34 to move to a position connected with the conveying mechanism 2, so that the feeding bucket 1 on the conveying mechanism 2 can move to the first conveying structure 34.

[0105] In this embodiment, the first conveying structure 34 not only rises and falls along the frame 31 driven by the lifting structure 33, but the first conveying structure 34 can also convey the feeding bucket 1 thereon, so that the feeding bucket 1 can be quickly conveyed to the next link after the lifting is completed, thereby realizing automatic lifting and automatic transmission of the feeding bucket 1.

[0106] More specifically, frame 31 includes a support frame 311, columns 312, and guide rails 313. Support frame 311 is composed of channel steel and steel plates. It is placed on the ground and supports columns 312 and guide rails 313. Columns 312 are vertically mounted on support frame 311. Columns 312 are welded from square tubes and steel plates. Columns 312 are placed above support frame 311 and connected to guide rails 313. Guide rails 313 are machined from section steel and mounted on the inner sidewalls of columns 312. They serve to guide guide structure 32.

[0107] The guide structure 32 includes a guide frame 321 and a pulley assembly 322. The guide frame 321 is welded from square tubes and is located between the columns 312. The pulley assembly 322 consists of multiple pulleys and a fixed plate. The pulley assembly 322 is positioned on the side of the guide frame 321 and slides with the guide rail 313.

The height of the feeding barrel accommodating space 35 is higher than the height of the feeding barrel 1, so that the feeding barrel 1 output by the conveying mechanism 2 can enter the feeding barrel accommodating space 35, and then the feeding barrel 1 rises to a specified height driven by the lifting structure 33.

[0112] In some embodiments, the connection between the conveying mechanism 2 and the lifting mechanism 3 can be detachable. When the feeding bucket 1 needs to be loaded with materials, the conveying mechanism 2 and the lifting mechanism 3 are connected.

Its function is to receive the feeding bucket 1 delivered from the first conveying structure and convey the feeding bucket 1 so that the clamping structure 41 can grasp the feeding bucket 1.

[0114] When loading the feeding bucket 1, the first conveying structure 34 and the second conveying structure 43 are connected to transfer the feeding bucket 1 from the first conveying structure 34 to the second conveying structure 43. The stabilizing frame 42 is arranged above the second conveying structure 43 and is installed on the support platform 44.

The first conveying structure 34 and the second conveying structure 43 provided in this embodiment can ensure stable and continuous transportation of the feeding bucket 1.

[0117] In some embodiments, the gripping structure 41 includes a jaw track 413, a jaw 411, and a jaw drive assembly 412. The jaw track 413 is disposed on the top sidewall of the stabilizing frame 42.

The automatic charging system for a vacuum melting furnace in the present invention can adopt the automatic charging system for a vacuum melting furnace in the first aspect of the present invention, or can adopt other structures. For the convenience of explanation, the automatic charging system for a vacuum melting furnace in the second aspect of the present invention will be described in detail below.

[0123] Combine Figures 1 to 10 As shown, this embodiment discloses an automatic charging system for a vacuum melting furnace, including a charging barrel 1 , an automatic charging system for a vacuum melting furnace, a feeding mechanism 5 and a charging mechanism 6 .

[0124] The feeding mechanism 5 is connected to the automatic feeding system of the vacuum melting furnace.

[0125] The side of the feeding mechanism 6 is provided with a feeding port that can be opened and closed, and the feeding port of the feeding mechanism 6 corresponds to the discharge end of the feeding mechanism 5 .

[0126] When loading the feeding bucket 1, the automatic loading system of the vacuum melting furnace transfers the feeding bucket 1 to the feeding mechanism 5, the feeding port of the feeding mechanism 6 is opened, the feeding mechanism 5 extends into the interior of the feeding mechanism 6 and transfers the feeding bucket 1 into the feeding mechanism 6, the feeding mechanism 5 exits the feeding mechanism 6, and then the feeding port of the feeding mechanism 6 is closed.

[0127] When the feeding barrel 1 is withdrawn, the feeding port of the feeding mechanism 6 is opened, the feeding mechanism 5 extends into the feeding mechanism 6 and transfers the feeding barrel 1 to the automatic feeding system of the vacuum melting furnace, and the automatic feeding system of the vacuum melting furnace outputs the feeding barrel 1.

[0128] The above-mentioned automatic feeding system of the vacuum melting furnace realizes the automatic feeding of the feeding barrel 1 and the automatic output after unloading through the coordinated work of the feeding barrel 1, the automatic feeding system of the vacuum melting furnace, the feeding mechanism 5 and the feeding mechanism 6. No human participation is required in the whole process, which greatly improves production efficiency.

[0129] In some embodiments, the feeding barrel 1 is enclosed by thick steel plates, has a cylindrical outer shape and a vacuum interior, and is used to store raw materials. The feeding barrel 1 includes a barrel body 11 and a clamping portion 12. There are at least two clamping portions 12, each of which is arranged on the side of the barrel body 11. Preferably, the clamping portion 12 is arranged at the top position of the side wall of the barrel body 11. In this embodiment, the barrel body 11 is transported on the automatic loading system of the vacuum melting furnace in a supported manner, so there is no need to set a lifting hole on the barrel body 11. When the feeding barrel 1 is transferred on the automatic feeding system of the vacuum melting furnace, only the barrel body 11 of the feeding barrel 1 is in contact with the automatic feeding system of the vacuum melting furnace; when the feeding barrel 1 is transported to the inside of the feeding mechanism 6, the arranged clamping part 12 can directly contact the barrel support plate 623 of the feeding mechanism 6, and when the barrel support plate 623 of the feeding mechanism 6 rises, the barrel support plate 623 can lift the feeding barrel 1 as a whole upward, thereby enabling the feeding barrel 1 to be transferred from the automatic feeding system of the vacuum melting furnace to the barrel support plate 623.

[0130] In some embodiments, the feed mechanism 5 includes a feed mechanism frame 53, a feed slide plate 51, and a feed drive assembly 52. ​​The feed slide plate 51 is slidably mounted above the feed mechanism frame 53. The feed slide plate 51 is welded from steel plates and profiles and is used to store the feeding bucket 1 delivered by the gripping mechanism 4. The feed drive assembly 52 is connected to the feed slide plate 51 and is used to drive the feed slide plate 51 to move. The feed drive assembly 52 uses a servo motor and chain drive to drive the feed slide plate 51 to move into the secondary charging chamber of the vacuum melting furnace to unload the feeding bucket 1.

[0131] More specifically, the feed drive assembly 52 includes a servo motor 521, a fifth sprocket 522, a sixth sprocket 523, a seventh sprocket 524, a third chain 525, and a fourth chain 526. The servo motor 521 is mounted on the feed mechanism frame 53. The sixth and seventh sprockets 523 and 524 are both rotatably mounted on the feed mechanism frame 53. The central axes of the sixth and seventh sprockets 523 and 524 are coplanar. The fifth sprocket 522 is connected to the output shaft of the servo motor 521. The third chain 525 is sleeved between the fifth and sixth sprockets 522 and 523. The fourth chain 526 is sleeved between the sixth and seventh sprockets 523 and 524. A connecting plate 527 is provided at the bottom end of the feed slide plate 51. The connecting plate 527 is connected to the side of the fourth chain 526.

[0132] In some embodiments, the feeding mechanism 6 includes a feeding chamber 61, a feeding barrel guide structure 62 and a feeding guide drive structure 63. The side of the feeding chamber 61 is provided with a feeding port that can be opened and closed, and the bottom of the feeding chamber 61 is provided with a discharge port that can be opened and closed. The feeding barrel guide structure 62 is slidably assembled inside the feeding chamber 61 and can move vertically along the feeding chamber 61. The feeding guide drive structure 63 is connected to the feeding barrel guide structure 62 and is used to drive the feeding barrel guide structure 62 to rise and fall in the feeding chamber 61. In this embodiment, the feeding barrel guide structure 62 can lift the clamping portion 12 of the feeding barrel 1, and the barrel body portion of the feeding barrel 1 is only in contact with the second feeding sliding plate section 512, thereby enabling the feeding barrel 1 to be transferred between the feeding barrel guide structure 62 and the feeding sliding plate 51.

[0133] More specifically, the feeding guide driving structure 63 includes a second driving motor 631, a second driving sprocket set 632 and a driving chain. The second driving motor 631 is used to drive the second driving sprocket set 632 to rotate, thereby driving the driving chain to rise and fall.

[0134] The feeding barrel guide structure 62 includes a slide rail 622, a slider 621 and a barrel support plate 623. There are at least two slide rails 622, each of which is vertically arranged on the inner wall of the feeding chamber 61. The slide rail 622 is welded from a profile and a steel plate, and its function is to provide support for the slider 621. Preferably, the slide rails 622 are symmetrically arranged inside the shell. There are at least two sliders 621, each of which is slidably assembled on the slide rail 622. The slider 621 is welded from a steel plate, fixedly connected to the second drive sprocket set 632 by a chain, and moves vertically up and down along the slide rail 622. There are at least two barrel support plates 623, each of which extends inward and is connected to the side wall of a slider 621. The barrel support plate 623 is welded from steel plates and fixed to the lower side of the slider 621 by bolts. Its function is to connect with the barrel 1 in a snap-fit ​​manner after the barrel 1 enters the barrel guide structure 62, thereby driving the barrel 1 to move up and down through the up and down movement of the slider 621.

[0135] When loading the feeding barrel 1, the feeding port of the feeding mechanism 6 is opened, the feeding slide plate 51 is driven to extend into the feeding chamber 61, the barrel support plate 623 contacts the clamping portion 12 of the feeding barrel 1, and the barrel support plate 623 is driven by the feeding guide drive structure 63 to rise, so that the feeding barrel 1 is separated from the feeding slide plate 51. When retracting the feeding barrel 1, the feeding port of the feeding mechanism 6 is opened, the feeding slide plate 51 moves below the barrel support plate 623 supporting the feeding barrel 1, and the barrel support plate 623 is driven by the feeding guide drive structure 63 to place the feeding barrel 1 on the feeding slide plate 51.

[0136] In this embodiment, since the barrel support plate 623 and the feeding barrel 1 are fixed by a snap-fit ​​method, it is not easy for the feeding barrel 1 to fall off accidentally during the transportation process, thereby ensuring the stability of the feeding barrel 1 during the transportation process. In this embodiment, the barrel support plate 623 can hold up the snap-fit ​​portion 12 on the feeding barrel 1, and by using a combination of slide rails and sliders, it can ensure that the movement trajectory of the feeding barrel during the ascent or descent process is more precise and stable. Compared with the hoisting method, this embodiment can avoid the problem of shaking of the feeding barrel 1 during the lifting process. The entire loading and unloading process of the feeding barrel 1 can be automatically completed by the feed sliding plate and the feeding guide drive structure without manual intervention, which reduces labor intensity and also speeds up the production rhythm.

[0137] In some embodiments, the clamping portion 12 is provided with a snap-in interface, and the top of the barrel support plate 623 is provided with a snap-in protrusion that engages with the snap-in interface. In this embodiment, the snap-in protrusion on the top of the barrel support plate 623 engages with the clamping portion 12, thereby further strengthening the connection between the barrel support plate 623 and the feeding bucket 1. This ensures that the feeding bucket 1 is firmly positioned on the barrel support plate 623, reducing safety risks caused by loosening or slipping of the feeding bucket 1 during transportation. This snap-in structure allows for precise positioning of the feeding bucket 1, ensuring its positional accuracy during ascent and descent, thereby improving the operational accuracy of the entire system.

[0138] A limiting structure is provided inside the feeding chamber 61. The limiting structure is used to limit the lifting position of the feeding barrel guide structure 62, thereby controlling the forward and reverse rotation or stopping of the second drive motor 631, preventing the movement of the feeding barrel guide structure 62 beyond the set stroke, and playing a safety role. The limiting structure is a mechanical limiter or an infrared limiter, and other types of limiting structures can also be used. The specific form is not limited here. The arrangement position of the limiting structure can be arranged one at the upper and lower parts of the inner side wall of the feeding chamber 61, or two or more can be arranged in the feeding chamber 61.

[0139] In some embodiments, the feeding chamber 61 includes a housing 611, a door panel 612, and a gate valve 613. The housing 611 is welded from steel plates into a hollow rectangular parallelepiped, providing space for unloading the feeding barrel 1. A door panel 612 is provided at the side of the feeding port of the feeding chamber 61. The door panel 612 is connected to a door panel drive structure 614. The door panel 612 is driven by the door panel drive structure 614 to move laterally to open and close the feeding port. The door panel 612 is machined from a thick rectangular steel plate and serves to seal the housing 611 to achieve a vacuum environment. Among them, the door panel driving structure 614 can be a screw driving structure, including a second screw, a second nut, a connecting block and a second screw driving motor. The second screw is rotatably set on the outer wall of the feeding chamber 61, the second screw is set horizontally, and the second nut is threadedly equipped with the second screw. The side wall of the second nut is connected to the door panel 612 through the connecting block, and then the door panel driving structure 614 can drive the door panel 612 to move, thereby realizing the opening and closing of the feed port.

[0140] In the past, vacuum melting furnaces were fed from the side, a single method that resulted in complex feeding procedures and unreliable operation, leading to reduced performance and a shorter service life of the vacuum melting furnace. To address this issue, in some embodiments, a discharge port is provided at the bottom of the feeding chamber 61. A gate valve 613 is provided at the bottom discharge port of the feeding chamber 61. The gate valve 613 is connected to a gate valve drive structure 615. The gate valve 613 controls the opening and closing of the discharge port under the drive of the gate valve drive structure 615. In this embodiment, the feeding method of the feeding chamber 61 is improved to allow feeding from the top of the vacuum melting furnace, and the feeding process can be controlled by the gate valve 613.

[0141] The working process of the automatic charging system of the vacuum melting furnace is as follows:

[0142] Taking raw material A as an example, a set weight of raw material A is first added to the feeding bucket 1 in advance, and the feeding bucket 1 filled with raw material A is placed on the conveying mechanism 2 through an automatic transfer tool. The conveying mechanism 2 starts to rotate and transfers the feeding bucket 1 to the first conveying structure 34 located below the guide frame 321 of the lifting mechanism 3.

[0143] After the feeding bucket A reaches the first conveying structure 34, the first drive motor 331 in the lifting structure 33 is activated, driving the first, second, and third sprockets to rotate, which in turn drives the second chain 333 to move. The second chain 333 then drives the guide frame 321 upward along the guide rail 313 under the rolling action of the pulley block 322. When the first conveying structure 34 and the second conveying structure 43 in the gripping mechanism 4 are aligned at the same height, the first conveying structure 34 below the guide frame 321 begins to rotate, conveying the feeding bucket 1 therein to the second conveying structure 43.

[0144] An infrared sensor is provided inside the clamping structure 41 to detect the real-time position of the feeding barrel 1. When it is detected that the feeding barrel 1 reaches the set position, the second conveying structure 43 stops rotating, and the clamping structure 41 starts to perform the grabbing action, grabbing the feeding barrel 1 and placing it on the upper surface of the feed sliding plate 51, and then the clamping structure 41 releases the feeding barrel 1 and returns to the origin.

[0145] Then, the gate valve 613 below the housing 611 is closed, isolating the feeding chamber 61 from the vacuum environment of the vacuum melting furnace. The door panel 612 of the feeding chamber 61 is then opened. Simultaneously, the feed drive assembly 52 is activated, driving the feed slide 51 to move along the axis of the feed slide 51 to one side, feeding the feeding bucket 1 on the upper surface of the feed slide 51 through the lower edge of the housing 611 into the feeding bucket guide structure 62 in the feeding mechanism 6. At this point, the bucket support plate 623 on the slider 621 is lower than the upper edge of the feeding bucket 1.

[0146] When the feeding barrel 1 reaches the set position, the second drive motor 631 is activated, driving the slider 621 upward along one side of the slide rail via the second drive sprocket assembly 632. The barrel support plate 623 on the slider 621 then moves upward and snaps into contact with the upper edge of the feeding barrel 1, removing the feeding barrel 1 from the upper surface of the feed slide plate 51. The feeding barrel 1 is now suspended and detached from the upper surface of the feed slide plate 51. The feed drive assembly 52 is then activated, driving the feed slide plate 51 to move along the other side of the feed slide plate 51 axis and exit the housing 611. At this point, the door panel 612 of the feeding chamber 61 is closed, creating a vacuum environment. The gate valve 613 below the housing 611 is then opened to connect to the vacuum environment of the vacuum melting furnace. The second drive motor 631 is then activated, driving the slider 621 downward along one side of the slide rail via the second drive sprocket assembly 632. The bucket support plate 623 on the slider 621 then moves downward, driving the feeding bucket 1 downward until the bottom of the feeding bucket 1 reaches a certain distance above the crucible of the vacuum melting furnace. The discharge port of the feeding bucket 1 is then opened to allow the feeding operation.

[0147] When raw material A in feeding bucket 1 is completely emptied, the second drive motor 631 is activated, driving the slider 621 upward along one side of the slide rail via the second drive sprocket assembly 632. The bucket support plate 623 on the slider 621 then moves upward, driving the feeding bucket 1 upward until it reaches the set retracted position. The gate valve 613 below the housing 611 is then closed, isolating the feeding chamber 61 from the vacuum environment of the vacuum melting furnace.

[0148] At this time, the door panel 612 of the feeding chamber 61 is opened again, and then the feeding drive assembly 52 is started, driving the feeding slide plate 51 to move to one side along the axis of the feeding slide plate 51. When the upper surface of the feeding slide plate 51 is flush with the bottom of the feeding barrel 1 after unloading, the second driving motor 631 is started, and the slider 621 is driven to move downward along one side of the slide rail through the second driving sprocket assembly 632. The barrel support plate 623 on the slider 621 moves downward accordingly, driving the feeding barrel 1 after unloading to move downward. When the upper surface of the feeding slide plate 51 is completely in contact with the bottom of the feeding barrel 1 after unloading, the slider 621 continues to move downward for a certain distance, so that the barrel support plate 623 is separated from the upper edge of the feeding barrel 1. Then the feeding drive assembly 52 is started, driving the feeding slide plate 51 to move to the other side along the axis of the feeding slide plate 51, driving the feeding barrel 1 to move out of the feeding chamber 61. When the clamping structure 41 detects that the feeding bucket 1 has reached the set position, the clamping structure 41 starts to perform a grabbing action, grabs the feeding bucket 1 and places it on the second conveying structure 43. At the same time, the door panel 612 of the feeding chamber 61 is closed.

[0149] The second conveying structure 43 rotates, transporting the unloaded charging bucket 1 to the first conveying structure 34 below the guide frame 321. The first drive motor 331 of the lifting structure 33 is activated, driving the guide frame 321 downward along the guide rail 313 under the rolling action of the pulley block 322. When it reaches the ground, the first conveying structure 34 below the guide frame 321 begins to rotate, transporting the unloaded charging bucket 1 therein to the conveying mechanism 2.

[0150] Then the conveying mechanism 2 starts to convey the feeding barrel 1 along the other side of the axis of the conveying mechanism 2. Finally, the automatic transfer tool returns the unloading feeding barrel 1 to the preparation area to wait for the next feeding, and this cycle repeats.

[0151] This new system, by installing multiple automated conveying and lifting devices, effectively saves space compared to existing technologies. It only requires basic maintenance personnel and does not require excessive manual labor. It significantly improves the efficiency of feeding time and greatly saves manpower and time costs. The new system uses various sensors and servo motors to better ensure the stability and safety of continuous feeding.

[0152] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
