Description

Technical Field

[0001] This utility model relates to the field of waste removal technology for automatic production of refractory bricks, specifically a waste removal device for automatic production of refractory bricks. Background Technology

[0002] Refractory bricks are an important type of refractory material, made from refractory clay, high-alumina bauxite, siliceous or magnesia raw materials, etc., through high-temperature firing. They possess excellent high-temperature resistance, thermal shock resistance, and erosion resistance. Their shapes are mostly standard brick types, but custom-shaped bricks can also be made to order. Refractory bricks are widely used in high-temperature industries such as steel, cement, glass, and ceramics. As lining materials for critical components such as furnace linings and kiln walls, they effectively protect equipment structures, extend service life, and reduce energy consumption. Depending on their composition and application, refractory bricks can be divided into various types, including clay bricks, high-alumina bricks, silica bricks, and magnesia bricks, to meet the needs of different industrial scenarios.

[0003] In the existing refractory brick production process, there are serious problems with the sorting of defective products. Currently, it mainly relies on manual operation, where workers need to check the size, appearance, strength, and other indicators of each refractory brick on the production line. This is not only extremely inefficient, with a large amount of time wasted on manual screening, resulting in a slow overall production pace, but also susceptible to subjective factors. Different workers have different standards, and fatigue after long hours of work can easily lead to missed inspections and misjudgments. Once defective products enter the market, it will affect the product quality reputation and cause economic losses to the company. There is an urgent need to improve the sorting method. Therefore, we need a waste rejection device for automatic refractory brick production. Utility Model Content

To address the problems of low efficiency and error-proneness in the sorting of defective refractory bricks in the existing technology, which relies on manual operation, this application achieves accurate identification and efficient recycling of defective products by setting up a linkage between laser detection feedback and an automated sorting mechanism. When a defective product is detected, the software system automatically triggers the first motor to drive the double-headed screw, which pushes the defective product to the sorting area through the linkage between the threaded sleeve and the connecting plate. Subsequently, the second motor drives the threaded rod, which moves the pneumatic gripper to move the defective product above the recycling bin and releases it.

To address the problems in existing technologies where refractory bricks are difficult to clamp stably for different sizes during transport, and their positions are prone to shifting during transport, affecting the accuracy of subsequent testing, this application proposes a third motor that drives a linkage structure including a fixed rod, gears, and racks. This allows a movable plate to move the clamping arm and clamping plate, which, in conjunction with a sliding sleeve sliding along the support rod, effectively clamps refractory bricks of different sizes and allows for flexible adjustment of their positions. This design ensures that the refractory bricks remain centered on the conveyor belt and are stably transported to the laser sensor for accurate testing, improving testing efficiency and accuracy and ensuring the smooth operation of the production process.

[0015] 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.

[0016] This utility model embodiment provides a waste removal device for automatic refractory brick production, such as... Figure 1 and Figure 2As shown, the system includes a conveyor belt 1, with refractory bricks 2 on top of the conveyor belt 1, a clamping assembly 3 fixedly connected to the top of the conveyor belt 1, a laser sensor 4 fixedly connected to the top of the conveyor belt 1, an adjusting assembly 5 at the bottom of the conveyor belt 1, and a recycling bin 6 on one side of the conveyor belt 1. The clamping assembly 3 includes a fixing frame 301, which is fixed to the top of the conveyor belt 1. A first motor 302 is fixedly connected to the bottom of the fixing frame 301. The output shaft of the first motor 302 is fixedly connected to a double-ended screw 303 through a coupling. A threaded sleeve 304 is threadedly connected to the outer wall of the double-ended screw 303. A connecting block 305 is hinged to the bottom of the threaded sleeve 304. A connecting plate 306 is hinged to one end of the connecting block 305. A slider 307 is fixedly connected to one side of the connecting plate 306. A sliding rod 308 is slidably connected inside the slider 307. A second motor 307 is fixedly connected to the bottom of the connecting plate 306. 9. The output shaft of the second motor 309 is fixedly connected to a threaded rod 310 through a coupling. A threaded connecting sleeve 311 is threadedly connected to the outer wall of the threaded rod 310. A pneumatic gripper 312 is fixedly connected to the bottom of the threaded connecting sleeve 311. When a defective product is detected, the laser detection feeds the data back to the software system, automatically starting the first motor 302, which drives the double-headed screw 303 to rotate. Its two independent threads cause the two threaded sleeves 304 to move in different directions, thereby driving the connecting block 305, connecting plate 306, and slider 307 to slide along the sliding rod 308. After reaching the appropriate position, the pneumatic gripper 312 is activated to clamp the defective product. Then the second motor 309 is activated to drive the threaded rod 310 to rotate, pushing the threaded connecting sleeve 311, so that the pneumatic gripper 312 moves with the defective product. When it moves above the recycling bin 6, the pneumatic gripper 312 is released, and the defective refractory brick 2 falls into the recycling bin 6 to complete the recycling.

[0017] Furthermore, such as Figure 2 As shown, the second motor 309 forms a threaded structure with the threaded rod 310 and the threaded connecting sleeve 311. One end of the threaded rod 310 is threaded through the threaded connecting sleeve 311 and connected thereto, while the other end of the threaded rod 310 is connected to the output end of the second motor 309. The second motor 309 can drive the threaded rod 310 to rotate and push the threaded connecting sleeve 311 through it.

[0018] Furthermore, such as Figure 2 As shown, the threaded sleeve 304 forms a linkage structure with the connecting plate 306 through the connecting block 305. The bottom of the threaded sleeve 304 is hinged to one end of the connecting block 305, and the other end of the connecting block 305 is hinged to the top of the connecting plate 306. Through the threaded sleeve 304, the threaded sleeve 304 can drive the connecting block 305 to move, and the connecting block 305 can drive the connecting plate 306 to push.

[0019] Furthermore, such as Figure 2 As shown, the connecting plate 306 forms a sliding structure with the slider 307 and the slide rod 308. The outer diameter of the slide rod 308 matches the inner diameter of the slider 307, and the outer wall of the slide rod 308 is fitted to the inner wall of the slider 307. Through the connecting plate 306, the connecting plate 306 can drive the slider 307 to move, and the slider 307 can slide along the outer wall of the slide rod 308.

[0020] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the adjustment assembly 5 includes a third motor 501, which is located at the bottom of the conveyor belt 1. The output shaft of the third motor 501 is fixedly connected to a fixed rod 502 via a coupling. A gear 503 is fixedly connected to the outer wall of the fixed rod 502. A rack 504 is meshed with one side of the gear 503. A movable plate 505 is fixedly connected to the top of the rack 504. A sliding sleeve 506 is fixedly connected to the bottom of the movable plate 505. A slide rail 507 is slidably connected to the inner wall of the sliding sleeve 506. A clamping arm 508 is fixedly connected to the top of the movable plate 505. A clamping plate 509 is fixedly connected to one side of the clamping arm 508. A clamping plate 509 is fixedly connected to one side of the clamping plate 509. The sliding sleeve 510 has a support rod 511 slidably connected to its inner wall. The refractory brick 2 is placed on the conveyor belt 1 and started to transport it. The third motor 501 is started, which drives the fixed rod 502 and gear 503 to rotate, thereby causing the rack 504 to move. This causes the movable plate 505 and the sliding sleeve 506 to slide along the slide rail 507. The movable plate 505 drives the clamping arm 508 and the clamping plate 509 to clamp the refractory brick 2. The clamping plate 509 drives the sliding sleeve 510 to slide along the support rod 511. This completes the clamping of refractory bricks 2 of different sizes and adjusts their position to ensure that the refractory brick 2 is centered on the conveyor belt 1 and stably transported to the laser sensor 4 for detection.

[0021] Furthermore, such as Figure 3 As shown, the third motor 501 forms a rotating structure with the gear 503 via the fixed rod 502. One end of the fixed rod 502 is fixedly connected to the output shaft of the third motor 501, and the outer wall of the fixed rod 502 is fixedly connected to the inner wall of the gear 503. The third motor 501 can drive the fixed rod 502 to rotate, which in turn drives the gear 503 to rotate.

[0022] Furthermore, such as Figure 3As shown, the rack 504 forms a linkage structure with the clamping arm 508 through the movable plate 505, and the top of the rack 504 is fixedly connected to the bottom of the movable plate 505, and the top of the movable plate 505 is fixedly connected to the clamping arm 508. Through the rack 504, the rack 504 can drive the movable plate 505 to move, and the movable plate 505 can drive the clamping arm 508 to move.

[0023] Working principle: First, refractory brick 2 is placed on conveyor belt 1. Starting conveyor belt 1 allows it to transport refractory brick 2. Starting the third motor 501 rotates the fixed rod 502, which in turn rotates the gear 503. The gear 503 then moves the rack 504, which in turn moves the movable plate 505. The movable plate 505 then moves the sliding sleeve 506, which slides along the slide rail 507. The movable plate 505 drives the clamping arm 508 to move, which in turn drives the clamping plate 509 to clamp the refractory brick 2. The clamping plate 509 then drives the sliding sleeve 510 to move, allowing the sliding sleeve 510 to slide along the support rod 511. This process clamps refractory bricks 2 of different sizes and adjusts their position, ensuring they remain centered and stably transported to the laser sensor 4 for detection. When a defective product is detected, the laser detection data is sent back to the software system. The system then automatically starts the first motor 302, which drives the double-ended screw 303 to move. The double-ended screw 303 rotates by passing through two threaded sleeves 304 with two independent threads, allowing the two threaded sleeves 304 to move in different directions. The threaded sleeves 304 drive the connecting block 305 to move, which in turn drives the connecting plate 306 to move. The connecting plate 306 then drives the slider 307 to move, allowing the slider 307 to slide along the sliding rod 308. When it reaches the... When the product is in the appropriate position, the pneumatic gripper 312 is activated to clamp the defective product. By activating the second motor 309, the second motor 309 drives the threaded rod 310 to rotate, which in turn pushes the threaded connecting sleeve 311 through it. This causes the threaded connecting sleeve 311 to move the pneumatic gripper 312, which in turn moves the defective product. When the defective product moves above the recycling bin 6, the pneumatic gripper 312 is released, allowing the defective refractory brick 2 to fall into the recycling bin 6 for recycling.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
