Description

Technical Field

[0001] This application relates to the field of tin furnace technology, and more specifically, to a tin furnace that is easy to handle. Background Technology

[0002] Tin is a silvery-white metal that is soft and has good ductility. It is also a low-melting-point metal with a melting point of 232°C. Tin ingots are the product form of tin smelters and are the basic raw material for all deep processing of tin. When producing solder such as tin bars, tin balls, and tin wires in factories, tin ingots need to be processed. The first step is to melt the tin ingots in a tin furnace. Heating elements are used to heat the crucible in the tin furnace. When the tin ingots are melted into molten tin, they are placed in a casting mold for cooling and shaping.

[0003] To optimize the tin ingot melting process, existing technologies typically employ mechanical stirring mechanisms. During crucible heating, these mechanisms use controllable-speed stirring blades to accelerate the convection circulation of molten tin, effectively improving heat transfer efficiency and enhancing the uniformity of tin ingot heating. Once the tin ingot is completely melted, a specially designed scoop is needed to manually transfer the molten tin into a pre-prepared casting mold. However, the stirring mechanism may cause interference during the material handling process, increasing operational complexity and creating safety hazards in the confined workspace, thus affecting material handling operations and hindering efficiency improvements. Summary of the Invention

[0004] The purpose of this application is to provide a tin furnace that facilitates material handling, which can solve the technical problem that the stirring mechanism of the tin furnace may cause interference during the material handling process, which not only increases the complexity of operation, but also creates safety hazards in a narrow working space, affects the material handling operation, and restricts the improvement of work efficiency.

[0037] like Figures 1 to 3As shown, this application embodiment provides a tin furnace for easy material handling, including a tin furnace body 1, a crucible 2 and a first mounting frame 3 located above the crucible 2 inside the tin furnace body 1, a second mounting frame 4 rotatably mounted on the bottom of the first mounting frame 3, a mounting plate 5 hinged on the second mounting frame 4, a stirring assembly 6 for stirring the molten tin in the crucible 2 mounted on the mounting plate 5, a swing drive assembly 7 for swinging the mounting plate 5 mounted on the second mounting frame 4, a rotation drive assembly 8 for rotating the second mounting frame 4 mounted on the first mounting frame 3, and a lifting drive assembly 9 for lifting the first mounting frame 3 mounted on the tin furnace body 1.

[0038] In use, tin ingots are placed in crucible 2 and heated to form molten tin. While heating, the molten tin in crucible 2 is stirred by stirring component 6. When it is necessary to remove material, stirring component 6 is stopped, and then lifting drive component 9 drives first mounting frame 3 to rise. Stirring component 6 rises with first mounting frame 3 until it leaves crucible 2. Then, swing drive component 7 drives mounting plate 5 to swing upward. Stirring component 6 swings upward with mounting plate 5. At the same time, rotation drive component 8 drives second mounting frame 4 to rotate. Stirring component 6 rotates with second mounting frame 4 until stirring component 6 extends out of the operating port of tin furnace body 1 and moves away from the operator's material removal position. Then, material removal can be performed.

[0039] This device, through coordinated lifting, rotation, and swinging movements, enables the stirring component 6 to quickly and automatically move away from the crucible 2, expanding the working space, reducing interference with operators, facilitating material handling, reducing safety hazards, and improving work efficiency. The device features a lifting drive component 9 to adjust the axial stirring depth of the stirring component 6, a swinging drive component 7 to adjust the radial stirring angle of the stirring component 6, and a rotation drive component 8 to adjust the circumferential stirring position of the stirring component 6. This allows for different stirring requirements, enhancing the device's applicability and stirring coverage. The stirring component 6 flexibly adjusts its position and movement within the crucible 2, achieving efficient stirring of the molten tin and material handling avoidance.

[0040] like Figures 1 to 5 As shown, in this embodiment, the stirring assembly 6 includes a first motor 61 and a stirring rod 62.

The first motor 61 is fixedly mounted on the mounting plate 5, and the output shaft of the first motor 61 is connected to the stirring rod 62.

[0041] When in use, the first motor 61 is turned on to drive the stirring rod 62 to rotate, and the stirring blades of the stirring rod 62 stir the molten tin in the crucible 2.

[0042] like Figures 1 to 5As shown, in this embodiment, the swing drive assembly 7 includes a second motor 71, a screw 72, a slide bar 73, a movable block 74, and a connecting rod 75. The screw 72 is rotatably mounted on the second mounting bracket 4 via a bearing. The output shaft of the second motor 71 is connected to the screw 72. The slide bar 73 is fixedly mounted on the second mounting bracket 4. The movable block 74 is threaded onto the screw 72 and slidably mounted onto the slide bar 73. A through slot 41 is provided on the second mounting bracket 4. The connecting rod 75 passes through the through slot 41 and is hinged between the movable block 74 and the mounting plate 5.

[0043] When in use, the second motor 71 is turned on to drive the screw 72 to rotate. The screw 72 drives the movable block 74 to move along the slide bar 73. The movable block 74 drives the mounting plate 5 to swing through the connecting rod 75. The stirring assembly 6 swings together with the mounting plate 5. The cooperation between the movable block 74 and the slide bar 73 plays a guiding and limiting role for the movable block 74.

[0044] like Figure 1 and 2 As shown, in this embodiment, the rotation drive assembly 8 includes a third motor 81 and a rotating rod 82. The rotating rod 82 is rotatably mounted on the first mounting bracket 3 via a bearing, and the rotating rod 82 is fixedly connected to the second mounting bracket 4. The output shaft of the third motor 81 is connected to the rotating rod 82.

[0045] When in use, the third motor 81 is turned on to drive the rotating rod 82 to rotate, the second mounting bracket 4 rotates together with the rotating rod 82, and the stirring assembly 6 rotates together with the second mounting bracket 4.

[0046] like Figure 1 and 2 As shown, in this embodiment, a slider 42 is fixedly provided on the top of the second mounting bracket 4, and an annular groove 31 is provided on the bottom of the first mounting bracket 3. The slider 42 is slidably connected to the annular groove 31.

[0047] The cooperation between the slider 42 and the annular groove 31 makes the second mounting bracket 4 rotate more smoothly and steadily, improving its stability.

[0048] like Figure 1 and 2 As shown, in this embodiment, the lifting drive assembly 9 includes a cylinder 91, which is fixedly mounted on the tin furnace body 1, and the piston rod end of the cylinder 91 is connected to the first mounting bracket 3.

[0049] When in use, the cylinder 91 is turned on to drive the first mounting frame 3 to move up and down, and the stirring component 6 moves up and down together with the first mounting frame 3.

[0050] like Figure 1 and 2As shown, in this embodiment, a guide rod 32 is fixedly provided on the top of the first mounting frame 3, and the guide rod 32 is slidably connected to the top of the solder pot body 1; the cooperation between the guide rod 32 and the solder pot body 1 can limit the first mounting frame 3 to only make vertical movements, prevent horizontal deviation during the lifting process, and improve the stability of use.

[0051] like Figure 1 and 2 As shown, in this embodiment, a reinforcing rib 33 is provided at the connection between the piston rod end of the cylinder 91 and the first mounting bracket 3; the triangular reinforcing rib 33 is welded to the connection between the piston rod end of the cylinder 91 and the first mounting bracket 3 to form a rigid support, disperse the concentrated load, and avoid stress concentration leading to fracture.

[0052] Working principle: When using the tin furnace provided in this application, which is easy to handle, tin ingots are placed in crucible 2 and heated to form molten tin. At the same time as heating, the first motor 61 is turned on to drive the stirring rod 62 to rotate. The stirring blades of the stirring rod 62 stir the molten tin in crucible 2.

[0053] When material needs to be removed, stop the stirring assembly 6, then activate cylinder 91 to raise the first mounting frame 3. The stirring assembly 6 rises with the first mounting frame 3 until it leaves the crucible 2. Then, activate the second motor 71 to rotate the screw 72. The screw 72 moves the movable block 74 along the slide bar 73. The movable block 74 drives the mounting plate 5 to swing upward through the connecting rod 75. The stirring assembly 6 swings upward with the mounting plate 5. At the same time, activate the third motor 81 to rotate the rotating rod 82. The second mounting frame 4 rotates with the rotating rod 82. The stirring assembly 6 rotates with the second mounting frame 4 until the stirring assembly 6 extends out of the operating port of the tin furnace body 1 and moves away from the operator's material removal position. Then, the material removal operation can be carried out.

[0054] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
