[0002] An aluminum alloy sprocket is a sprocket made of aluminum alloy material. Aluminum alloy has the advantages of light weight, high strength, corrosion resistance, etc., so it is widely used in various mechanical equipment. The manufacturing process of aluminum alloy sprockets is exquisite. Through high-precision processing and heat treatment, the accuracy and strength of the sprockets are ensured. The surface of the sprockets has been specially treated, with high hardness and wear resistance, and can maintain good performance during long-term use. The advantages of aluminum alloy sprockets include light weight, which can reduce the weight of the entire mechanical equipment and improve the transportation and handling efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-4, the present utility model provides a technical solution: a melting furnace for producing aluminum alloy rear sprockets, including a housing 1, a feed inlet 2, heating tubes 3, a motor 4, a limit block 5, a lead screw 6, a rotating ring 7, a pushing rod 8, a connecting ring 9, a material tray 10, a sliding groove 11, a rotating rod 12, a slag collection box 13, a rotating plate 14, a filter screen 15, a partition screen 16, and a blanking pipe 17.

[0029] Embodiment 1

[0030] The melting furnace for producing aluminum alloy rear sprockets is provided with a rotating melting structure, and the rotating melting structure can make the materials evenly heated and melted on the material tray 10. Specifically:

[0031] The side surface of the housing 1 is provided with a feed inlet 2, and further includes heating tubes 3. The heating tubes 3 are arranged in the inner wall sandwich of the housing 1. The housing 1 is connected with a rotating melting structure. The rotating melting structure drives the material tray 10 to move through the rotation of the lead screw 6, so that the rotating ring 7 drives the material tray 10 to move. The rotating melting structure includes a motor 4. The motor 4 is installed on the upper surface of the housing 1, and the lower end of the motor 4 is connected with a limit block 5. The lower surface of the limit block 5 is connected with a lead screw 6. The lower surface of the limit block 5 is penetrated and installed with a telescopic rod, and the lower end of the telescopic rod is installed on the upper surface of the rotating ring 7. The outer surface of the rotating ring 7 is installed with a pushing rod 8, and the lower end of the rotating ring 7 is rotatably connected with a connecting ring 9. The outer surface of the connecting ring 9 is installed with a material tray 10. The outer surface of the material tray 10 is symmetrically provided with convex blocks, and the convex blocks are slidably installed in the sliding groove 11. The sliding groove 11 is installed on the inner wall surface of the housing 1. The upper surface of the material tray 10 is equally spaced with slots, and the pushing rod 8 is arranged in a comb-shaped structure;

[0032] When the melting furnace for producing aluminum alloy rear sprockets is in use, as Figure 2 shown, first, the aluminum alloy materials enter the housing 1 through the feed inlet 2, and the materials fall above the material tray 10. At this time, the heating tubes 3 are turned on for heating, and at the same time, the motor 4 is turned on, so that the limit block 5 rotates. Then, the limit block 5 drives the rotating ring 7 to rotate on the upper surface of the connecting ring 9 through the telescopic rod, so that the pushing rod 8 arranged on the outer surface of the rotating ring 7 rotates, and the materials on the upper surface of the material tray 10 are pushed, so that the materials are evenly heated. At the same time, when the limit block 5 rotates, it drives the lead screw 6 to rotate. Since the outer surface of the lead screw 6 is rotatably connected with the connecting ring 9, and the material tray 10 provided on the outer surface of the lead screw 6 is provided with convex blocks slidably installed in the sliding groove 11, the connecting ring 9 moves downward on the outer surface of the lead screw 6, and the connecting ring 9 drives the material tray 10 and the rotating ring 7 to move downward together. The telescopic rod on the upper surface of the rotating ring 7 will expand when moving downward. The temperature at the bottom inside the housing 1 is relatively high, and the molten liquid melted from the aluminum alloy will leak through the slots on the upper surface of the material tray 10. The materials slowly enter the high-temperature area, so that the heating process during melting is buffered, the waste residue after melting can be reduced, and the quality of the subsequent produced aluminum alloy rear sprockets can be better.

[0033] Example 2

[0034] The melting furnace for producing the aluminum alloy rear sprocket is also provided with a slag collection structure. The slag collection box 13 of the slag collection structure rotates to intercept the waste slag in the molten liquid. Specifically:

[0035] The lower end of the lead screw 6 is connected with a slag collection structure. The slag collection structure can make the rotary plate 14 of the slag collection box 13 open to collect waste slag by rotating the lead screw 6. The slag collection structure includes a rotating rod 12. The rotating rod 12 is installed on the lower surface of the lead screw 6 and is rotatably installed on the upper surface of the partition net 16. The partition net 16 is arranged on the inner wall surface of the outer shell 1. Two slag collection boxes 13 are symmetrically arranged on the lower surface of the rotating rod 12. The front surface of the slag collection box 13 is rotatably installed with a rotary plate 14. The rear surface of the slag collection box 13 is provided with a filter screen 15. The lower surface of the outer shell 1 is provided with a blanking pipe 17. The partition net 16 is arranged in a mesh structure;

[0036] When the aluminum alloy is melted into molten liquid, it will contain some waste slag. At this time, the molten liquid on the upper layer of the partition net 16 is filtered by the mesh-structured partition net 16, so that the waste slag is intercepted above the partition net 16. At the same time, the lead screw 6 drives the rotating rod 12 to rotate, so that the rotating rod 12 drives the slag collection box 13 on the lower surface to rotate. When the slag collection box 13 rotates, the rotary plate 14 installed on the front surface will be impacted by the molten liquid and thus rotate and open. After the molten liquid enters the interior of the slag collection box 13, the waste slag will be intercepted by the filter screen 15 arranged on the rear surface of the slag collection box 13, so that the waste slag flows inside the slag collection box 13, reducing the waste slag in the molten liquid and improving the quality of the molten liquid output. Finally, the molten liquid is discharged through the blanking pipe 17.

[0037] Working principle: When using the melting furnace for producing the aluminum alloy rear sprocket, a rotary melting structure is provided. The rotary melting structure can make the materials on the material tray 10 be evenly heated and melted by the pushing of the pushing rod 8. A slag collection structure is also provided. The slag collection box 13 of the slag collection structure rotates to intercept the waste slag in the molten liquid, increasing the overall practicability.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
