Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for aluminum melting furnaces, specifically to a feeding mechanism for an aluminum melting furnace. Background Technology

[0002] In the production and processing of aluminum products, aluminum melting furnaces are commonly used equipment. Their main function is to heat and melt aluminum ingots into molten aluminum for subsequent processing steps such as casting.

[0003] Traditionally, aluminum ingots and other raw materials are fed into the aluminum melting furnace manually. Workers use forklifts, cranes, or manual handling to move the ingots to the open crucible of the furnace and then place them inside. Using forklifts or cranes is inaccurate, and manual handling is time-consuming and labor-intensive. Furthermore, workers near the furnace face the risk of burns from the high temperatures, necessitating improved safety measures.

[0004] To improve feeding accuracy, efficiency, and safety, conveyors (belt conveyors, chain conveyors) or elevators (bucket elevators, chain elevators) are currently used to transport aluminum ingots from the raw material area to the crucible opening of the aluminum melting furnace. The use of conveyors or elevators avoids workers approaching the aluminum melting furnace and enables mechanical feeding, thus improving feeding accuracy, efficiency, and safety.

[0005] However, aluminum ingots are stacked in piles and bundled with straps or steel bands when leaving the manufacturer's warehouse. When using conveyors or elevators to transport aluminum ingots to the aluminum melting furnace, the stacked ingots cannot be used directly; they must be unstacked first. That is, a robotic arm must be used to place the aluminum ingots one by one onto the conveyor so that the conveyor can transport them smoothly; or, a robotic arm must be used to tilt the aluminum ingots onto the bottom of the elevator so that the elevator can lift and transport them.

[0006] The aforementioned material feeding method, which combines a conveyor (or elevator) and a robotic arm, requires two separate systems—the robotic arm and the conveyor (or elevator)—thus increasing the floor space required. Therefore, reducing the floor space and improving space utilization is a key technical challenge that needs to be addressed. Utility Model Content

[0007] To address the aforementioned shortcomings of existing technologies, this invention proposes a feeding mechanism for an aluminum melting furnace, which can reduce the floor space required and improve space utilization.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A feeding mechanism for an aluminum melting furnace includes an aluminum melting furnace body, a column, a crossbeam, a rotating assembly, a lifting assembly, an electromagnetic chuck, and an aluminum ingot stack. The top of the aluminum melting furnace body is provided with a crucible opening. The column is located on one side of the aluminum melting furnace body. The middle part of the crossbeam is rotatably connected to the top of the column in a horizontal plane. The rotating assembly is located on the top of the column and is used to drive the crossbeam to rotate in a horizontal plane. Lifting assemblies are provided at both ends of the crossbeam. An electromagnetic chuck is provided at the output end of the lifting assembly. One electromagnetic chuck is located above the crucible opening, and the other electromagnetic chuck is located above the aluminum ingot stack.

[0009] Furthermore, the lifting assembly includes a lifting telescopic component, a guide component, and a lifting seat. The lifting telescopic component is located at the end of the cross frame, and the output end of the lifting telescopic component is provided with a lifting seat. The lifting seat is slidably connected to the end of the cross frame in the vertical direction through the guide component, and the bottom of the lifting seat is provided with the electromagnetic chuck.

[0010] Furthermore, the guide component includes a guide rod and a sleeve. The bottom of the guide rod is located on the lifting seat, and the sleeve is located at the end of the crossbeam. The guide rod and the sleeve slide in a vertical direction.

[0011] Furthermore, it also includes a covering assembly, which includes a rotating frame, a cover plate, and a covering telescopic component. The middle part of the rotating frame is rotatably connected to the side of the lifting seat in a vertical plane. The lower part of the rotating frame has a vertical part, and the bottom of the vertical part has a cover plate. The upper part of the rotating frame has a horizontal part, which is rotatably connected to the lower end of the covering telescopic component. The upper end of the covering telescopic component is rotatably connected to the upper part of the lifting seat. When the covering telescopic component is in its shortest state, the cover plate is located directly below the electromagnetic chuck.

[0012] Furthermore, the rotating assembly includes a motor frame, a motor, a reducer, a drive gear, and a driven gear. The motor is mounted on the upper part of the column, and the reducer is mounted on the motor frame. The input end of the reducer is connected to the output end of the motor, and the output end of the reducer is equipped with a drive gear. The driven gear is located in the middle of the crossbeam, and the drive gear and the driven gear cooperate with each other.

[0013] Furthermore, the bottom of the cross frame is provided with a support cylinder, the top of the column is provided with a central shaft, the central shaft is rotatably connected to the inner ring of the support cylinder through a bearing, and the outer ring of the support cylinder is provided with the driven gear.

[0014] The beneficial effects of this utility model are: 1. This utility model uses rotary motion instead of linear conveying. With the column as the center and the crossbeam as the diameter, the entire feeding mechanism rotates in a vertical space. The material picking point and feeding point can be covered by rotation alone, eliminating the need for long-distance conveying lines. The site occupation is optimized from "planar" to "point-based", reducing the equipment base area and improving space utilization.

[0015] 2. This utility model adopts a dual-station design: when one electromagnetic chuck is performing the feeding action at the open crucible, the other electromagnetic chuck can simultaneously retrieve material from the aluminum ingot stack. The exchange between the "retrieving" and "feeding" actions can be completed with one rotation of the crossbeam, saving idle waiting time, making the operation cycle more compact, and improving feeding efficiency.

[0016] 3. The covering component can reduce heat loss from the aluminum melting furnace body by covering the crucible opening after the aluminum ingot is put in. This not only reduces energy consumption but also maintains a stable furnace temperature, which is beneficial to improving smelting quality and efficiency.

[0017] 4. The covering component is not a separate additional device, but is integrated into the lifting base, making the overall feeding mechanism compact and further improving space utilization.

[0018] 5. The lifting telescopic component provides the main power, and in conjunction with the guide rod and sleeve, it improves the stability of the lifting seat and the electromagnetic chuck at its bottom during the lifting process, and enhances the reliability of material picking and unloading.

[0021] To better understand this utility model, it will be further described below with reference to the accompanying drawings. It is worth noting that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings. They are used for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Example 1: like Figure 1 , Figure 2 and Figure 3 As shown, an aluminum melting furnace feeding mechanism includes an aluminum melting furnace body 1, a column 2, a crossbar 3, a rotating assembly 4, a lifting assembly 5, an electromagnetic chuck 6, and an aluminum ingot stack.

[0023] See Figure 1 and Figure 2 The top of the aluminum melting furnace body 1 is provided with a crucible opening 101. When aluminum ingots are added, they are added through the crucible opening 101; when molten aluminum is poured out, it is poured out through the crucible opening 101.

[0024] See Figure 1 The column 2 is located on one side of the aluminum melting furnace body 1, and the column 2 is fixedly installed on the ground.

[0025] See Figure 1 The middle part of the cross frame 3 is rotatably connected to the top of the column 2 in the horizontal plane via the rotating component 4.

[0026] Specifically, see Figure 1 and Figure 4The rotating assembly 4 includes a motor frame 401, a motor 402, a reducer 403, a drive gear 404, and a driven gear 405. The motor frame 401 is fixedly mounted on the upper part of the column 2. The reducer 403 is fixedly mounted on the motor frame 401. The output end of the motor 402 is connected to the input end of the reducer 403, and the drive gear 404 is fixedly mounted on the output end of the reducer 403. A support cylinder 301 is fixedly mounted at the bottom of the cross frame 3, and a central shaft 201 is fixedly mounted at the top of the column 2. The central shaft 201 is rotatably connected to the inner ring of the support cylinder 301 via bearings. The driven gear 405 is fixedly mounted on the outer ring of the support cylinder 301 and meshes with the drive gear 404. When the motor 402 is started, power is transmitted to the driven gear 405 via the reducer 403 and the drive gear 404, thereby driving the entire cross frame 3 to rotate around the column 2 in the horizontal plane.

[0027] See Figure 2 A lifting assembly 5 is installed at both ends of the cross frame 3. The lifting assembly 5 includes a lifting telescopic component 501, a guide component, and a lifting seat 502. The lifting telescopic component 501 (e.g., a hydraulic cylinder or electric push rod) is vertically fixed to the end of the cross frame 3. The lifting seat 502 is fixedly installed at the output end of the lifting telescopic component 501. The guide component includes a guide rod 503 and a sleeve 504. The sleeve 504 is fixed to the end of the cross frame 3, the bottom of the guide rod 503 is fixed to the lifting seat 502, and the upper part of the guide rod 503 is inserted into the sleeve 504 and can slide vertically, thereby guiding and stabilizing the lifting movement of the lifting seat 502. An electromagnetic chuck 6 is installed at the bottom of each lifting seat 502.

[0028] See Figure 3 At the initial workstation, one electromagnetic chuck 6 is positioned directly above the aluminum ingot stack, and another electromagnetic chuck 6 is positioned directly above the crucible opening 101 of the aluminum melting furnace body 1. The aluminum ingot stack is formed by stacking multiple layers of aluminum ingots 7, which are elongated strips. The aluminum ingot stack can be transported to its position by workers using forklifts or overhead cranes.

[0029] The work process is as follows: First, the lifting assembly 5 located above the aluminum ingot stack activates, driving the electromagnetic chuck 6 below it to descend and pick up several aluminum ingots 7 before rising. Then, the rotating assembly 4 drives the horizontal frame 3 to rotate 180°, causing the electromagnetic chuck 6 carrying the aluminum ingots 7 to rotate above the crucible opening 101, while the empty electromagnetic chuck 6 rotates above the aluminum ingot stack. Next, the lifting assembly 5 above the crucible opening 101 drives the electromagnetic chuck 6 to descend, de-energizing it and releasing the aluminum ingots 7, which fall into the crucible for melting. The lifting assembly 5 then drives the electromagnetic chuck 6 to move upward away from the crucible opening 101. Simultaneously, the lifting assembly 5 above the aluminum ingot stack drives the electromagnetic chuck 6 to descend and pick up the next batch of aluminum ingots 7, preparing for the next work cycle. The two electromagnetic chucks 6 work alternately, achieving continuous feeding operations.

[0030] Through the above working process, it can be seen that this embodiment has the following advantages: First, this embodiment uses rotary motion instead of linear conveying. With column 2 as the center and crossbeam 3 as the diameter, the entire feeding mechanism rotates in a vertical space. The material pick-up point and feeding point can be covered by rotation alone, eliminating the need for long-distance conveying lines. The site occupation is optimized from "planar" to "point-based", reducing the equipment base area and improving space utilization.

[0031] Secondly, this embodiment adopts a dual-station design: when one electromagnetic chuck 6 performs the feeding action at the crucible opening 101, the other electromagnetic chuck 6 can simultaneously retrieve material from the aluminum ingot stack. The exchange of the "retrieving" and "feeding" actions can be completed with one rotation of the crossbeam 3, saving idle waiting time, making the operation cycle more compact, and improving feeding efficiency.

[0032] Third, the lifting telescopic component 501 provides the main power, and in conjunction with the guide rod 503 and the sleeve 504, it improves the stability of the lifting seat 502 and the electromagnetic chuck 6 at its bottom during the lifting process, and improves the reliability of the material picking and unloading process.

[0033] Example 2: This embodiment 2 is an improvement upon embodiment 1: See Figure 5 and Figure 6 A cover assembly 8 is also installed on the side of the lifting seat 502. The cover assembly includes a rotating frame 801, a cover plate 802, and a cover telescopic member 803. The middle part of the rotating frame 801 is rotatably connected to the side of the lifting seat 502 in the vertical plane via a pivot. The lower part of the rotating frame 801 is a vertical part, and the cover plate 802 is fixedly installed at its bottom. The cover plate 802 is preferably made of ceramic plate or graphite plate. The upper part of the rotating frame 801 is a horizontal part. The lower end of the cover telescopic member 803 (e.g., a cylinder) is rotatably connected to the horizontal part, and its upper end is rotatably connected to the upper part of the lifting seat 502.

[0034] The working principle is as follows: After the electromagnetic chuck 6 is de-energized and releases the aluminum ingot 7 into the crucible, the cover telescopic component 803 retracts, pulling the rotating frame 801 to rotate, causing the cover plate 802 to swing downwards. When the cover telescopic component 803 retracts to its shortest state, the cover plate 802 is directly below the electromagnetic chuck 6. At this point, see [the diagram / reference needed]. Figure 5 Then, the lifting assembly 5 drives the cover plate 802 to move down, and the cover plate 802 covers the crucible opening 101 to reduce heat loss.

[0035] When it is necessary to open the crucible opening 101, the lifting component 5 drives the cover plate 802 to move upward, so that the cover plate 802 and the electromagnetic chuck 6 move upward together away from the aluminum melting furnace body 1, thereby opening the crucible opening 101.

[0036] When the electromagnetic chuck 6 is needed to pick up the aluminum ingot 7, the cover telescopic component 803 extends, driving the rotating frame to rotate in the opposite direction 801, causing the cover plate 802 to rotate to the side of the electromagnetic chuck 6. (See below for further details.) Figure 6 The cover plate 802 will not obstruct the electromagnetic chuck 6 from picking up the aluminum ingot 7.

[0037] Based on the above working principle, it can be seen that Embodiment 2 has the following advantages: The covering component 8 reduces heat loss from the aluminum melting furnace body 1 by covering the crucible opening 101 after the aluminum ingot 7 is added. This not only reduces energy consumption but also maintains a stable furnace temperature, which is beneficial for improving smelting quality and efficiency.

[0038] The covering component 8 is not a separate additional device, but is integrated into the lifting seat 502, which makes the overall feeding mechanism compact and further improves the space utilization.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
