Description

Technical Field

[0001] This application relates to the field of refractory material production technology, specifically a mullite refractory brick turning mechanism after molding. Background Technology

[0002] When forming mullite refractory bricks, to facilitate demolding, the textured or grooved side faces upwards. Mechanical gripping typically requires grasping the large flat surface of the brick for stable handling, stacking, or kiln loading. The bottom-facing position after forming makes it difficult for the gripping mechanism to directly and effectively grasp the target surface.

[0003] Currently, the common practice is to manually flip the bricks. This method has significant problems: manual flipping is slow, becoming a bottleneck for automated production lines; refractory bricks are heavy, manual flipping is labor-intensive, and manual operation easily leads to bricks bumping, falling, causing edge damage or even overall breakage, affecting product quality and yield; high-temperature environments (some brick blanks require heat treatment) and heavy-load handling pose safety risks. Therefore, there is an urgent need for a mullite refractory brick flipping mechanism after molding to connect the molding process with the subsequent gripping and handling process. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide a mullite refractory brick turning mechanism after molding, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a mullite refractory brick forming and turning mechanism, comprising a frame, wherein the frame is rotatably connected to a turning frame via two connecting shafts, the turning frame is provided with two parallel conveying structures, and the conveying structures are connected to the turning frame via an adjustment mechanism, a positioning plate is provided between the two conveying structures, and the two ends of the positioning plate are fixedly connected to the turning frame, a turning motor for driving the turning frame to rotate is provided at one end of the frame, the power output shaft of the turning motor passes through the frame and is connected to a first gear, a first external gear ring meshes with the outer side of the first gear, the first external gear ring is fixed on one of the connecting shafts, and a drive structure for providing power to the conveying structures is provided on the other side of the frame.

[0006] Furthermore, the adjustment mechanism includes a screw and nuts. The screw is fixedly connected to the tilting frame, and there are two nuts, which are screwed onto the screw and located on both sides of the tilting frame.

[0007] Furthermore, the drive structure includes a drive motor, a drive gear, a double gear ring assembly, a second gear, a first sprocket, a chain, and a second sprocket. The drive motor is located on one side of the frame, and the drive motor's power output shaft passes through the frame and is connected to the drive gear. The drive gear meshes with the double gear ring assembly on its outer side. The double gear ring assembly is rotatably connected to a connecting shaft. Two second gears mesh with the outer side of the double gear ring assembly. One end of the second gear is rotatably connected to the tilting frame via a shaft, and the other end of the shaft is equipped with a first sprocket. The first sprocket is connected to the second sprocket via a chain, and the second sprocket is mounted on the conveying structure.

[0008] Furthermore, the double gear ring assembly includes a second external gear ring and a third external gear ring, which are rigidly connected by a sleeve and coaxially arranged. The second external gear ring meshes with the drive gear, and the third external gear ring meshes with the second gear.

[0009] Furthermore, the conveying structure includes a fixed plate, a rotating roller, and a conveyor belt. There are two fixed plates and two rotating rollers. The rotating rollers are rotatably connected between the two fixed plates. The outer sides of the two rotating rollers are connected by the conveyor belt.

[0013] Compared with the prior art, this application, through the setting of two parallel conveying structures, can still carry out conveying operations after flipping. The adjustment mechanism realizes the adjustment of the distance between the two conveying structures, which is compatible with different specifications of brick blanks. Through the setting of the positioning plate, the material brick can be positioned. When the material brick moves to the positioning plate, the flipping motor drives the first gear to rotate, and the first external gear ring drives the flipping frame and the two conveying structures to flip. The drive structure drives the conveying structure to transport the flipped material brick, reducing the labor intensity of workers and improving the material feeding efficiency.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0021] Please see Figure 1-5 This application provides a technical solution for a mullite refractory brick forming and turning mechanism: a mullite refractory brick forming and turning mechanism includes a frame 1, and the frame 1 is rotatably connected to a turning frame 3 through two connecting shafts 2 inside the frame 1.

[0022] Furthermore, the tilting frame 3 includes side plates 4 and support rods 5. There are two side plates 4, which are connected by four support rods 5. The side plates 4 are connected to the frame 1 through connecting shafts 2.

[0023] The frame 1 is a welded steel structure frame with bearing seat holes symmetrically opened on both side walls. Two coaxial connecting shafts 2 pass through the side walls of the frame via bearings to realize the rotation support of the tilting frame 3. The two side plates 4 of the tilting frame 3 are rigidly connected by four support rods 5 to form a stable frame structure.

[0024] The tilting frame 3 has two parallel conveying structures 6 inside. The conveying structure 6 includes a fixed plate 7, a rotating roller 8 and a conveyor belt 9. There are two fixed plates 7 and two rotating rollers 8. The two fixed plates 7 are rotatably connected by the rotating rollers 8.

[0025] The roller 8 is mounted on the fixed plate 7 via bearings, and the conveyor belt 9 is sleeved on the outside of the two rollers 8 to form a conveying plane. One end of one of the rollers 8 is connected to the second sprocket 21 in the drive structure 15, and the two conveying structures 6 move in the same direction.

[0026] Furthermore, at least two connecting rods 10 are provided between the two rotating rollers 8. The two ends of the connecting rods 10 are connected to the fixed plate 7. The connection rods 10 can improve the stability of the fixed plate 7 and limit the movement of the material bricks during the flipping process.

[0027] Furthermore, the conveying structure 6 is connected to the tilting frame 3 via an adjustment mechanism.

[0028] Furthermore, the adjustment mechanism includes a screw 24 and a nut 25. The screw 24 is fixedly connected to the tilting frame 3. There are two nuts 25, which are screwed onto the screw 24 and located on both sides of the support rod 5 in the tilting frame 3. By adjusting the position of the two nuts 25, the distance between the two conveying structures 6 can be precisely controlled to accommodate bricks of different widths.

[0029] A positioning plate 11 is provided between the two conveying structures 6, and both ends of the positioning plate 11 are fixedly connected to the tilting frame 3.

[0030] Furthermore, a positioning plate 11 is fixed in the middle of the two side plates 4. The positioning plate 11 can position the material brick and support it when it is flipped to prevent the brick from bending or deforming during the flipping process.

[0031] One end of the frame 1 is provided with a flipping motor 12 that drives the flipping frame 3 to rotate. The power output shaft of the flipping motor 12 passes through the frame 1 and is connected to the first gear 13. The outer side of the first gear 13 is meshed with a first external gear ring 14, which is fixed on one of the connecting shafts 2.

[0032] The flipping motor 12 is fixed to the frame 1 by bolts. When the flipping motor 12 is started, it drives the connecting shaft 2 and the flipping frame 3 to rotate 180° around the axis through gear transmission, thereby flipping the brick.

[0033] A drive structure 15 that provides power to the conveying structure 6 is provided on the other side of the frame 1.

[0034] Furthermore, the drive structure 15 includes a drive motor 16, a drive gear 17, a double gear ring assembly, a second gear 18, a first sprocket 19, a chain 20, and a second sprocket 21. The drive motor 16 is located on one side of the frame 1. The power output shaft of the drive motor 16 passes through the frame 1 and is connected to the drive gear 17. The double gear ring assembly meshes with the outer side of the drive gear 17. The double gear ring assembly is rotatably connected to the connecting shaft 2. Two second gears 18 mesh with the outer side of the double gear ring assembly. One end of the second gear 18 is rotatably connected to the tilting frame 3 through a shaft, and the other end of the shaft is equipped with a first sprocket 19. The first sprocket 19 is connected to the second sprocket 21 through the chain 20. The second sprocket 21 is mounted on the conveying structure 6.

[0035] Furthermore, the double gear ring assembly includes a second external gear ring 22 and a third external gear ring 23, which are rigidly connected by a sleeve and coaxially arranged. The second external gear ring 22 meshes with the drive gear 17, and the third external gear ring 23 meshes with the second gear 18.

[0036] The double gear ring assembly of the drive structure is made of forged steel in one piece. Its second external gear ring 22 meshes with the drive gear 17, and its third external gear ring 23 meshes with the second gear 18. The two external gear rings are coaxially rigidly connected through interference fit to ensure synchronous power transmission.

[0037] With this configuration, the drive motor 16 drives the drive gear 17 to rotate, which in turn drives the second outer gear ring 22 and the third outer gear ring 23 to rotate. The second gear 18, which meshes with the third outer gear ring 23, drives the first sprocket 19 to rotate. The chain 20 drives the second sprocket 21 to rotate, which in turn drives the rotating roller 8 to rotate. The rotating roller 8 then drives the conveyor belt 9 to rotate, thus transporting the bricks.

[0038] When in use: the tilting frame 3 is in a horizontal position. By adjusting the position of the two nuts 25, the distance between the two conveying structures 6 can be precisely controlled to accommodate bricks of different widths.

[0039] Material feeding and conveying: The drive motor 16 starts, and the drive motor 16 drives the drive gear 17 to rotate, thereby driving the second outer gear ring 22 and the third outer gear ring 23 to rotate. The second gear 18, which meshes with the third outer gear ring 23, drives the first sprocket 19 to rotate. The chain 20 drives the second sprocket 21 to rotate, thereby driving the roller 8 to rotate. The roller 8 drives the conveyor belt 9 to rotate, and the brick blank is sent to the positioning plate 11 to complete the positioning.

[0040] Tilting operation: The connecting shaft 2 and the tilting frame 3 are rotated 180° around the axis by gear transmission to realize the tilting of the brick. The brick blank is inverted with the two conveyor belts 9 and the brick blank is moved out between the two conveyor belts 9.

[0041] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
