Description

Technical Field

[0001] The utility model relates to the technical field of accessories for roasting furnaces, and particularly relates to a feeding mechanism for a roasting furnace. Background Technique

[0002] In the casting process of train parts, a roasting furnace is mainly used for heat-treating materials or castings before casting. Through high-temperature treatment, the roasting furnace can effectively remove impurities and moisture in the materials, improve the purity and stability of the materials, and lay a good foundation for the subsequent casting process. The materials treated by roasting are more easily formed during the casting process, and the internal structure of the castings is more dense, reducing the generation of defects such as pores and shrinkage porosity, and improving the overall quality of the castings.

[0003] During the roasting in the existing parts casting process, some parts need to be placed on a material bearing frame and then sent into the roasting furnace. For loading and unloading, the frame needs to be taken out separately, and another trolley is set to transfer the frame out of the roasting furnace. In the automatic feeding machine for a zinc oxide production and smelting roasting furnace disclosed in the existing patent publication number CN216011755U, it includes a trolley mechanism and a pushing and pulling structure. The pushing and pulling structure drives the trolley mechanism, and the wheels of the trolley mechanism slide on the guide rail. In the above automatic feeding machine for the roasting furnace, the feeding is driven by a pushing and pulling structure, and the trolley mechanism is not convenient to directly move into the roasting furnace, and its usability still needs to be improved. In view of the above problems, a feeding mechanism for a roasting furnace is proposed. Content of the Utility Model

[0027] Please refer to Figures 1-4 , in this embodiment, a feeding mechanism for a roasting furnace includes a sealed door 11, a guide rail 15, and a material placing rack 12 connected to one side of the sealed door 11;

[0028] The bottom of the material placing rack 12 is connected with moving wheels 13 that can move on the guide rail 15, and a horizontal positioning plate 16 is connected to the guide rail 15;

[0029] Two sets of lifting grooves 21 connected to the outside are provided inside the sealing door 11. A positioning column 22 is slidably connected inside the lifting groove 21. A rotating rod 24 is rotatably connected inside the sealing door 11. A threaded area that is threadedly engaged with the positioning column 22 is provided on the rod body of the rotating rod 24 placed in the lifting groove 21. A third bevel gear 25 is installed on the rotating rod 24. A driving rod 20 is rotatably installed inside the sealing door 11. A fourth bevel gear 26 that meshes with the third bevel gear 25 is installed at the end of the driving rod 20. An adjusting member is installed on the sealing door 11 for adjusting the rotation of the driving rod 20.

[0030] A positioning hole 17 that is inserted and matched with the bottom end of the positioning column 22 is provided on the horizontal positioning plate 16.

[0031] Fixing members are connected to both sides of the sealing door 11 for fixing the sealing door 11 to one side of the roasting furnace.

[0032] In this embodiment, materials to be roasted can be placed on the material placing rack 12. The guide rail 15 extends into the roasting furnace. By operating the adjusting member to rotate the driving rod 20, the fourth bevel gear 26 can be driven to rotate. Thus, the rotating rod 24 is driven to rotate through the transmission of the third bevel gear 25. Driven by the threaded area, the height of the positioning column 22 can be adjusted. The bottom end of the positioning column 22 is inserted into the corresponding positioning hole 17, which can limit the horizontal movement of the mechanism. The material placing rack 12 is placed outside for loading and unloading materials. The fixing of the sealing door 11 can stabilize the position of the mechanism. When the material placing rack 12 is placed in the roasting furnace and the sealing door 11 is fixed to one side of the roasting furnace, the feeding of materials can be completed, facilitating subsequent roasting operations.

[0033] As Figure 3 shown, the adjusting member includes a first bevel gear 18 rotatably installed on the sealing door 11. An operating disk 34 is connected to the shaft end of the first bevel gear 18 and is arranged outside the sealing door 11. A second bevel gear 19 that meshes with the first bevel gear 18 is connected to the driving rod 20. Rotating the operating disk 34 can drive the first bevel gear 18 to rotate, thereby driving the driving rod 20 to rotate through the transmission of the second bevel gear 19.

[0034] As Figure 3 shown, the two sets of fourth bevel gears 26 are symmetrically arranged, and the helix directions of the two sets of threaded areas are opposite. When the driving rod 20 rotates, the two sets of rotating rods 24 rotate in opposite directions. The setting of the threaded area enables the two sets of positioning columns 22 to perform synchronous lifting and lowering.

[0035] As Figure 1 and Figure 3 shown, limiting sliders are connected to both sides of the positioning column 22. Limiting grooves 23 for the limiting sliders to slide are provided on both sides of the lifting groove 21.

[0036] As Figure 1 and Figure 3As shown, the fixing member includes a fixing plate 27 and a sleeve rod 28 connected to one side of the fixing plate 27. The fixing plate 27 is fixed to one side of the sealing door 11 by bolts. The sleeve rod 28 is slidably connected to a sliding rod 29. One end of the sliding rod 29 away from the fixing plate 27 is fixedly connected to a threaded seat 30. A screw rod 31 is threadedly connected to the threaded seat 30. One end of the screw rod 31 is connected to a turntable 32. One side of the sleeve rod 28 is connected to a handle 33. The setting of the handle 33 facilitates pushing or pulling the sealing door 11 to move.

[0037] In actual use, a screw hole corresponding to the screw rod 31 is opened on one side of the roasting furnace or a threaded sleeve corresponding to the screw rod 31 is installed. According to the installation position, the sliding rod 29 can be adjusted to slide in the sleeve rod 28, so that the screw rod 31 is connected to the target position, and the sealing door 11 is stably fixed on one side of the roasting furnace.

[0038] As Figure 1 and Figure 2 shown, at least two groups of the transverse positioning plates 16 are provided. When the mechanism moves away from the roasting furnace and the material placing rack 12 is moved out, the sealing door 11 can be fixed on one group of the transverse positioning plates 16. When the mechanism moves close to the roasting furnace, the sealing door 11 can be fixed on the transverse positioning plate 16 on the side close to the roasting furnace.

[0039] As Figure 1 shown, guide strips 14 are connected to both sides of the material placing rack 12. In actual use, a guide track for the guide strips 14 to slide can be arranged in the roasting furnace, which is beneficial to the stable feeding of the mechanism.

[0040] When the utility model is in use, materials to be roasted can be placed on the material placing rack 12. The guide rail 15 extends into the roasting furnace. Rotating the operation disk 34 can drive the first bevel gear 18 to rotate, and then drive the driving rod 20 to rotate through the transmission of the second bevel gear 19, which can drive the fourth bevel gear 26 to rotate, and then drive the rotating rod 24 to rotate through the transmission of the third bevel gear 25. Driven by the threaded area, the positioning column 22 can be adjusted in height. The two rotating rods 24 rotate in opposite directions. The setting of the threaded area enables the two positioning columns 22 to move up and down synchronously. The bottom end of the positioning column 22 is inserted into the corresponding positioning hole 17, which can limit the horizontal movement of the mechanism. The material placing rack 12 is placed outside for loading and unloading materials. The fixing of the sealing door 11 can stabilize the position of the mechanism. When the material placing rack 12 is placed in the roasting furnace and the sealing door 11 is fixed on one side of the roasting furnace, the feeding of materials can be completed, which is convenient for subsequent roasting operations. According to the installation position, the sliding rod 29 can be adjusted to slide in the sleeve rod 28, so that the screw rod 31 is connected to the target position, and the sealing door 11 is stably fixed on one side of the roasting furnace.

[0041] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms.
