Description

Technical Field

[0001] This utility model relates to the field of annealing furnace technology, and in particular to a high-stability roller conveyor for a roller hearth annealing furnace. Background Technology

[0002] A roller hearth annealing furnace is a continuous heat treatment equipment that uses internal roller conveyors to transport workpieces and completes the annealing process in a controlled atmosphere or protective gas environment. It is widely used in the mass production of metal sheets (such as steel plates, aluminum plates, and copper strips), glass, and ceramics.

[0003] The annealing furnace is equipped with conveyor rollers to facilitate the transport of workpieces. During transport, the workpieces need to be placed on the conveyor rollers. When the workpieces are placed off-center, they are located on one side of the rollers. The rollers are subjected to force on one side, resulting in uneven load and low stability during transport, which makes the rollers easy to damage. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable conveyor roller for a roller bottom annealing furnace, which solves the problem that when the roller conveys workpieces, the roller is subjected to force on one side, resulting in uneven load and easy damage to the roller.

[0005] To achieve the above objectives, a highly stable roller conveyor for a roller hearth annealing furnace is provided, comprising a base frame, side plates fixedly connected to both the left and right sides of the base frame, a plurality of output shafts rotatably connected between the side plates on the left and right sides, a conveyor roller body fixedly connected to the outer side of the plurality of output shafts, and a limit unit provided on the outer side of the conveyor roller body.

[0006] The limiting unit includes a moving ring, which is disposed on the outer side of the left and right ends of the conveying roller body. A base block is fixedly connected to the lower side of the moving ring. A rotating block 1 is fixedly connected to the outer side of the base block.

A lifting block is fixedly connected to the lower side of the rotating block 2. A lifting plate is fixedly connected to the lower side of the lifting block. An electric push rod is fixedly connected between the base frame and the lifting plate.

[0007] According to the high-stability roller conveyor of the roller hearth annealing furnace, a base plate is fixedly connected to the lower side of the lifting plate, and two stabilizing plates are fixedly connected to the upper side of the base plate. The upper side of the stabilizing plate passes through the upper side of the side plate and is fixedly connected to a protective plate.

[0008] According to the high-stability roller conveyor of the roller hearth annealing furnace, an extension plate is fixedly connected to the outer side of the moving ring, and the extension plate is arranged in a triangular structure.

[0009] According to the high-stability roller conveyor of the roller hearth annealing furnace, the stabilizing plate is slidably connected to the side plate.

[0010] According to the high-stability roller conveyor of the roller hearth annealing furnace, the moving ring is slidably connected to the conveyor roller body.

[0011] According to the high-stability roller conveyor of the roller hearth annealing furnace, the control board is set with an inclined structure.

[0012] According to the high-stability roller conveyor of the roller hearth annealing furnace, the bottom frame is configured with a U-shaped structure.

[0013] According to the high-stability roller conveyor of the roller hearth annealing furnace, the control plates on the left and right sides are symmetrically distributed.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] By incorporating side plates, an output shaft, a conveyor roller, a moving ring, a control plate, a lifting plate, a lifting block, and an electric push rod, the conveyor roller can control the moving rings and extension plates on both sides to move closer together when conveying workpieces, so that the workpiece is transported in the middle of the roller and avoids the roller being subjected to force on one side, thus preventing damage to the roller.

[0025] Example 1

[0026] Reference Figures 1-4 This utility model provides a high-stability roller conveyor for a roller bottom annealing furnace, comprising a base frame 2, with side plates 1 fixedly connected to both the left and right sides of the base frame 2. Multiple output shafts 3 are rotatably connected between the left and right side plates 1. Conveying roller bodies 4 are fixedly connected to the outer sides of the multiple output shafts 3. Limiting units 5 are provided on the outer side of the conveying roller bodies 4. The side plates 1, base frame 2, and limiting units 5 are all made of high-temperature resistant materials, specifically high-temperature resistant steel plate 310S. The electric push rod 512 is model AIDI-GT800, which has excellent high-temperature resistance. The base frame 2 is installed inside the furnace body.

[0027] The limiting unit 5 includes a moving ring 501, which is located on the outer sides of the left and right ends of the conveying roller body 4. A base block 503 is fixedly connected to the lower side of the moving ring 501. A rotating block 504 is fixedly connected to the outer side of the base block 503. A control plate 505 is rotatably connected to the outer side of each of the rotating blocks 504. A rotating block 506 is rotatably connected to the outer side of the lower end of the control plate 505. A lifting block 507 is fixedly connected to the lower side of the rotating block 506. A lifting plate 508 is fixedly connected to the lower side of the lifting block 507. An electric push rod 512 is fixedly connected between the bottom frame 2 and the lifting plate 508. An extension plate 502 is fixedly connected to the outer side of the moving ring 501, and the extension plate 502 has a triangular structure. The moving ring 501 is slidably connected to the conveying roller body 4. The control plate 501 is slidably connected to the conveying roller body 4. 5 is an inclined structure, and the bottom frame 2 is a U-shaped structure. The control plates 505 on the left and right sides are symmetrically distributed. When conveying the workpiece, the workpiece is placed on the conveying roller 4 for conveying. During the conveying process, the control electric push rod 512 drives the lifting plate 508 to descend. The lifting plate 508 drives the lifting block 507 to descend. The lifting block 507 drives the control plate 505 to rotate. The control plate 505 drives the moving ring 501 on the bottom block 503 to move. Since the moving rings 501 on both sides are symmetrically arranged, the moving rings 501 on both sides are brought closer to each other, so that the moving rings 501 drive the extension plate 502 to move. This makes it convenient for the moving rings 501 and the extension plate 502 to push the workpiece, so that the workpiece is concentrated in the middle of the conveying roller 4, avoiding the roller being subjected to force on one side and being damaged.

The stabilizing plate 510 is slidably connected to the side plate 1. The protective plates 511 on both sides can conveniently protect the workpiece and prevent the workpiece from shifting and touching the inner wall of the furnace.

[0031] Working principle: When in use, the workpiece is placed on the upper side of the conveyor roller 4. The conveyor roller 4 transports the workpiece. The electric push rod 512 is controlled to drive the lifting plate 508 to descend. Under the action of the control plate 505 and the bottom block 503, the moving rings 501 and the extension plate 502 on both sides are controlled to concentrate the workpiece in the middle of the conveyor roller 4, so as to avoid the roller being subjected to force on one side and the roller being damaged.
