Technical Field

[0001] This utility model belongs to the field of refractory fiber product manufacturing technology, and relates to a cutting device for strong and tough microporous plate products. Background Technology

[0002] The edges of the strong, microporous refractory fiberboard (CFFB) are irregular after molding, requiring edge trimming and reshaping. Square CFFB boards offer unique advantages, such as easier modular installation, reduced cutting waste, more even stress distribution, and higher installation efficiency. Traditionally, trimming square CFFB boards involves using one cutting machine to cut the left and right sides, then transferring the board to another cutting machine. During this transfer, the board is rotated 90 degrees to cut the front and back sides, resulting in a square CFFB board. This method has several drawbacks: first, it requires two cutting machines, leading to high equipment costs and low equipment utilization; second, the long conveying path, combined with the need for two cutting machines, results in a large overall equipment footprint and significant space consumption. Summary of the Invention

The distance sensor, position sensor, drive device, lifting cylinder, and conveyor roller are all connected to a controller circuit for controlling the operation of the lifting cylinder, drive device, and conveyor roller based on the positioning signals obtained by the position sensor and distance sensor.

Detailed Implementation

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of this utility model, and are not intended to limit the protection scope of this utility model.

[0017] Example: Please refer to Figure 1-3 This utility model provides the following technical solution: a strong and tough microporous plate product cutting device, applied to cutting square refractory fiberboard 8, including a conveyor roller 1 for conveying the refractory fiberboard 8, a cutting device 2 on the conveyor roller 1 for cutting the left and right sides of the refractory fiberboard 8; a lifting cylinder 3 is provided below the conveyor roller 1 on the outlet side of the cutting device 2, the upper end of the lifting cylinder 3 is connected to a connecting plate 31, the upper end of the connecting plate 31 is connected to multiple sets of columns 32, each set of columns 32 is located in the gap between two adjacent conveyor rollers 11 of the conveyor roller 1, and its upper end is connected to the lower end of a support plate 33, so that when the lifting cylinder 3 extends, the support plate lifts the refractory fiberboard 8; a U-shaped plate 4 is provided above the conveyor rollers 11, the left and right sides of the U-shaped plate 4 are connected to downwardly extending clamping plates 41, the top of which is connected to A rotating shaft assembly 5 is rotatably connected to a support frame 6 at its upper part. Its top end extends out of the support frame 6 and is connected to a drive device mounted on the support frame 6 to drive the U-shaped plate 4 to rotate. An L-shaped support arm 42 is fixed to the front side of the U-shaped plate 4. The front side of the L-shaped support arm 42 extends downward to form a baffle portion 43, which is used to prevent the refractory fiberboard 8 from moving forward. A position sensor 44 is connected to the lower end of the baffle portion 43. A distance sensor 63 is connected to the support frame 6 to detect the lifting distance of the refractory fiberboard 8. The distance sensor 63, position sensor 44, drive device, lifting cylinder 3, and conveyor roller 1 are all connected to a controller circuit to control the operation of the lifting cylinder 3, drive device, and conveyor roller 1 based on the positioning signals obtained by the position sensor 44 and distance sensor 63.

[0018] In operation, the conveyor roller 1 first rotates forward, transporting the refractory fiberboard 8. When the refractory fiberboard 8 passes the cutting device 2, its left and right sides are cut. It then continues to move forward until it is blocked by the baffle part 43 and stops on the conveyor roller 1. At this time, the position sensor 44 detects that the refractory fiberboard 8 has reached its position and sends the position signal to the controller, which then controls the conveyor roller 1 to stop. Then, the lifting cylinder 3 is extended to lift the refractory fiberboard 8 until it enters between the two clamping plates 41 of the U-shaped plate 4. At this time, the distance sensor 63 detects the position signal of the refractory fiberboard 8 and controls the lifting cylinder 3 to stop. Then, the control drive device drives the rotating shaft assembly 5 to rotate, causing the two clamping plates 41 and the baffle part 43 of the U-shaped plate 4 to rotate together, driving the refractory fiber board 8 to rotate 90 degrees and then stop. After the drive device stops, the controller controls the conveyor roller 1 to rotate in the reverse direction according to the built-in control program, and then controls the lifting cylinder 3 to retract until the refractory fiber board 8 falls onto the conveyor roller 1 and is conveyed backward to the cutting device 2 to cut the other two sides. At this time, the L-shaped support arm 42 fixed to the U-shaped plate 4 has not been reset, and the baffle part 43 is located on the side (left or right) of the conveyor roller 1. After the cutting is completed, the conveyor roller 1 moves forward, conveying the refractory fiber board 8 forward until it passes through the area of ​​the U-shaped plate 4. When it passes through the area of ​​the U-shaped plate 4, it is detected by the position sensor 44 and a position signal is sent to the controller, controlling the conveyor roller 1 to continue moving forward until the position signal disappears, indicating that the refractory fiber board 8 has passed through the area of ​​the U-shaped plate 4. Then the control drive device is reset, causing the baffle part 43 and the position sensor 44 to rotate 90 degrees and return to their initial positions. Repeat the above steps to cut the next piece of refractory fiberboard 8. The gap between the conveyor roller 1 and the U-shaped plate 4 is sufficient for the refractory fiberboard 8 to pass through, and the extension / retraction distance of the lifting cylinder 3 and the length of the column 32 are sufficient to lift the refractory fiberboard 8 to the height between the two clamping plates 41. The length of the support plate 33 is less than the length of the conveyor roller 11, while the width of the refractory fiberboard 8 is greater than the length of the support plate 33. During turning, the clamping plates 41 and the L-shaped support arm 42 will not interfere with the support plate 33.

[0019] To reduce wear between the refractory fiberboard 8 and the support plate 33 during rotation, the upper end of the support plate 33 is provided with a plurality of evenly distributed ball bearings 34.

[0020] The drive device can be a belt drive mechanism connected to the rotating shaft assembly 5, and the belt drive mechanism is connected to the motor or electric motor 7. In this preferred embodiment, the drive device includes a driven gear 51 fixed to the top of the rotating shaft assembly 5. The driven gear 51 meshes with a driving gear 71, and the center of the driving gear 71 is connected to the output shaft of the electric motor 7. The electric motor 7 is fixed to the support frame 6. The electric motor 7 is connected to the rotating shaft assembly 5 through a gear pair, allowing for precise position control. Removing the gears allows for easy replacement of the electric motor 7 or the rotating shaft assembly 5, facilitating maintenance.

[0021] To reduce dust hazards, a dust collection hood 21 is fitted over the cutting device 2 to extract the dust generated during cutting. Since there is only one cutting device 2, the number of dust collection devices is reduced, thus lowering costs.

[0022] To broaden its applicability, square fire-resistant fiberboards 8 of various sizes can be cut. The U-shaped plate 4 includes an insert plate 45 fixed to the lower end of the rotating shaft assembly 5. The upper part of the clamping plate 41 is provided with a slot 46. The insert plate 45 is inserted into the slot 46, allowing the spacing between the two clamping plates 41 to be adjusted. The top of the clamping plate 41 is provided with multiple threaded holes 47 for connecting bolts 48. The threaded holes 47 communicate with the slot 46, and are used to fix the position of the clamping plate 41 when the bolts 48 are tightened.

[0023] In one exemplary embodiment, the support frame 6 includes a portal frame 61, with a horizontal frame 62 fixedly connected to the upper part of the portal frame 61. The horizontal frame 62 is suspended above the conveyor roller conveyor 1. The upper part of the rotating shaft assembly 5 is rotatably connected to the horizontal frame 62, and the driving device is fixedly connected to the upper surface of the horizontal frame 62. The distance measuring sensor 63 is fixedly connected to the lower end of the horizontal frame 62.

[0024] The advantages of this embodiment are as follows: First, a single cutting device 2 cuts all four sides of the refractory board, reducing the number of cutting and dust removal devices and lowering equipment costs. Second, the steering mechanism is close to the cutting equipment, resulting in a short conveying distance and reduced space occupation. Third, the refractory fiberboard 8 is not driven by a gripping method, avoiding excessive local pressure on the refractory fiberboard 8 by the robotic arm and preventing damage, thus ensuring product quality. Fourth, the cutting, limiting, lifting, rotating, lowering, and traveling steps of the refractory fiberboard 8 are all completed automatically, with a high degree of automation, reducing human intervention, lowering labor intensity, avoiding the uncertainty of manual operation, reducing errors, and improving product quality.

[0025] In summary, this embodiment uses a single cutting device to automatically cut off the four edges of the refractory fiberboard 8, reducing equipment costs, occupying less space, and improving production efficiency and product quality.
