Description

Technical Field

[0001] This utility model relates to the field of ultra-low density (0.4 density) lightweight refractory brick preparation technology, specifically a lightweight refractory brick blanking device. Background Technology

[0002] Lightweight refractory brick blank separation refers to the process of cutting and separating lightweight refractory brick blanks after forming, drying and other processes according to predetermined specifications and dimensions. This step is crucial to ensuring the quality and dimensional accuracy of lightweight refractory bricks. Lightweight refractory brick blank separation equipment is an important piece of equipment in the field of refractory brick processing technology.

[0003] In the prior art, patent CN214561784U discloses a brick blank cutting device for refractory brick production, including a cutting mechanism and a pushing mechanism. The cutting mechanism includes a base, and two U-shaped rods are installed on the upper surface of the base. The two U-shaped rods are equipped with the same support frame II. The upper surface of the support frame II is equipped with a cutting mechanism. The top of the two U-shaped rods is equipped with the same screw. Both ends of the screw are rotatably connected to the two U-shaped rods respectively through a bearing I, and a handle is fixedly connected to one end of the screw. By setting the base and setting two U-shaped rods on the upper surface of the base, a sliding sleeve is slidably sleeved on the U-shaped rods, so that the support frame II can slide up and down on the U-shaped rods. This allows the height of the support frame II to be adjusted according to production needs, thereby enabling the cutting of brick blanks of different thicknesses.

[0004] This type of refractory brick production brick blank cutting device uses a pulley to drive a crank connecting rod mechanism to realize the periodic movement of the push plate. It requires many parts and has high requirements for the coordination efficiency of each part. The equipment itself has high cost and occupies a lot of working space. The screw drives the support frame to move, which is a slow and cumbersome process, affecting the efficiency of splitting lightweight refractory bricks. Utility Model Content

[0011] Furthermore, the conveying mechanism also includes an L-shaped plate, which is symmetrically fixedly connected to the upper surface of the blank-dividing platform. Ribs are provided at both ends of the conveying plate, and the ribs are installed in conjunction with the upper ends of the horizontally adjacent L-shaped plates to provide guidance and limit the movement of the conveying plate on the upper end of the blank-dividing platform.

[0012] Furthermore, the lifting mechanism includes a notch, a first connecting rod, a second connecting rod, and a connecting shaft.

[0016] 1. The motor drives the pulley mechanism, which in turn drives the conveyor plate to rotate via the transmission belt.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 This embodiment provides a technical solution: a lightweight refractory brick splitting device, including a splitting platform 1, a splitting frame 6 fixedly connected to the middle of the upper surface of the splitting platform 1, a lifting plate 4 inside the splitting frame 6, a cutting blade 5 at the lower end of the lifting plate 4, a controller 8 in the middle of the right side surface of the splitting frame 6, the input end of the controller 8 being electrically connected to an external power source, and also includes a conveying mechanism 2 and a lifting mechanism 3.

[0023] Conveying mechanism 2 includes a sliding chute 21, a support 22, a rotating shaft 23, a drive pulley 24, and a conveying plate 26. The sliding chute 21 is located in the middle of the blank-dividing platform 1. The lower end of the sliding chute 21 is fixedly connected to symmetrically distributed supports 22. A rotating shaft 23 is rotatably connected between two horizontally adjacent supports 22. A drive pulley 24 is fixedly connected to the middle of the front rotating shaft 23, and a driven pulley is fixedly connected to the middle of the rear rotating shaft 23. The driven pulley and the drive pulley 24 are connected by a transmission belt. Conveying plates 26 are fixedly connected to both the upper and lower ends of the transmission belt. Conveying mechanism 2 also includes a motor 25, which is located at the right end of the front support 22. The left end of the output shaft of the motor 25 is fixedly connected to the right end of the front rotating shaft 23. The input end of the motor 25 is electrically connected to the output end of the controller 8. Conveying mechanism 2 also includes... L-shaped plates 27 are symmetrically fixedly connected to the upper surface of the blanking platform 1. Ribs are provided at both ends of the conveyor plate 26. The ribs are installed in conjunction with the upper ends of the adjacent L-shaped plates 27. The motor 25 is driven by the controller 8. The output shaft of the motor 25 rotates, which drives the front shaft 23 to rotate. The front shaft 23 rotates, which drives the drive pulley 24 to rotate. In turn, the drive belt drives the driven pulley to rotate. The drive belt rotates, which moves the two conveyor plates 26. When the conveyor plate 26 reaches the front end of the blanking platform 1, the ribs at both ends of the upper conveyor plate 26 are slidably connected to the upper ends of the adjacent L-shaped plates 27. The two L-shaped plates 27 provide guidance and limit for the movement of the conveyor plate 26 on the upper surface of the blanking platform 1. At the same time, the upper conveyor plate 26 contacts the lightweight refractory brick and pushes the lightweight refractory brick backward.

[0024] Lifting mechanism 3: It is used to drive the lifting of the cutting blade 5. The lifting mechanism 3 includes a notch 31, a connecting rod 32, a connecting rod 33, and a connecting shaft 34. The notches 31 are symmetrically arranged on the upper end of the blank-separating frame 6. The interior of each notch 31 is rotatably connected to a connecting rod 32. The lower ends of two longitudinally adjacent connecting rods 32 are rotatably connected to the corresponding ends of the same connecting shaft 34. The upper end of each lifting plate 4 is rotatably connected to a connecting rod 33. The two longitudinally adjacent connecting rods 33 are rotatably connected to the corresponding ends of the vertically adjacent connecting shafts 34. The lifting mechanism 3 also includes a fixed seat 35 and an electric push rod 36. The fixed seat 35 is fixedly connected to the middle of the two connecting shafts 34 respectively. The electric push rod 36 is arranged between the two fixed seats 35. The input end of the electric push rod 36 is electrically connected to the output end of the controller 8. The left and right ends of the upper surface of the lifting plate 4 are fixedly connected to guide rods 7. The upper end of the blank-separating frame 6 is provided with symmetrically distributed sliding openings. The interior of each sliding opening is rotatably connected to the corresponding end of the vertically adjacent connecting shaft 34. The outer surfaces of the adjacent guide rods 7 are slidably connected. When the lightweight refractory brick reaches the required position, the controller 8 activates the electric push rod 36. The extension end of the electric push rod 36 extends and pushes both connecting shafts 34 to move away from the center of the lifting plate 4. The outward movement of the connecting shafts 34 drives the lower end of connecting rod 1 32 and the upper end of connecting rod 2 33 to move away from the center of the lifting plate 4. Connecting rod 1 32 and connecting rod 2 33 rotate away from the center of the lifting plate 4. The length of the support arm formed by connecting rod 1 32 and the vertically adjacent connecting rod 2 33 increases, thereby pushing the lifting plate 4 to move downward. The downward movement of the lifting plate 4 drives the cutting blade 5 to move downward. At the same time, the guide rods 7 slide inside the corresponding sliding openings to provide guidance for the movement of the lifting plate 4. When the cutting blade 5 contacts the lightweight refractory brick, it cuts the lightweight refractory brick. After the cutting is completed, the controller 8 activates the electric push rod 36, and the extension end of the electric push rod 36 retracts, thereby moving the cutting blade 5 upward.

[0025] The working principle of the lightweight refractory brick splitting device provided by this utility model is as follows: During operation, the operator first stably places the splitting platform 1, the splitting frame 6, and other mechanisms in a horizontal working area. After stable placement, the operator places the lightweight refractory bricks to be split onto the front end of the upper surface of the splitting platform 1 using an external conveying device. Then, the operator uses the controller 8 to activate the motor 25. The output shaft of the motor 25 rotates, driving the front rotating shaft 23 to rotate. The rotation of the front rotating shaft 23 drives the drive pulley 24 to rotate, thereby... The drive belt drives the driven pulley to rotate, which in turn moves the two conveyor plates 26. When the conveyor plates 26 reach the front end of the blanking table 1, the ribs at both ends of the upper conveyor plate 26 slide in connection with the upper ends of the adjacent L-shaped plates 27. The two L-shaped plates 27 provide guidance and limit for the movement of the conveyor plates 26 on the surface of the blanking table 1. At the same time, the upper conveyor plate 26 contacts the lightweight refractory brick, pushing it backward. When the lightweight refractory brick reaches the desired position, the operator activates the controller 8. When the electric push rod 36 is in operation, its telescopic end extends, pushing both connecting shafts 34 to move away from the center of the lifting plate 4. This outward movement of the connecting shafts 34 causes the lower ends of connecting rod 1 32 and the upper ends of connecting rod 2 33 to move away from the center of the lifting plate 4. Both connecting rod 1 32 and connecting rod 2 33 rotate away from the center of the lifting plate 4, increasing the length of the support arm formed by connecting rod 1 32 and the vertically adjacent connecting rod 2 33. This, in turn, pushes the lifting plate 4 downward, causing the cutting blade 5 to move downward. Meanwhile, the guide rods 7 slide inside the corresponding sliding openings, providing guidance for the movement of the lifting plate 4. When the cutting blade 5 contacts the lightweight refractory brick, it cuts the lightweight refractory brick. After the cutting is completed, the controller 8 activates the electric push rod 36, and the telescopic end of the electric push rod 36 retracts, thereby moving the cutting blade 5 upward. When the cutting blade 5 stops contacting the lightweight refractory brick, the controller 8 activates the motor 25, and the conveyor plate 26 continues to push the lightweight refractory brick backward, and then waits for the next cutting of the lightweight refractory brick.

[0026] It is worth noting that the controller 8 disclosed in the above embodiments controls the operation of the motor 25 and the electric push rod 36 using methods commonly used in the prior art.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
