Description

Technical Field

[0001] This invention relates to the field of powder processing, and more specifically, to a feeding and leveling device for a roller conveyor sintering furnace. Background Technology

[0002] Sintering is a key technology that uses high temperatures to induce physicochemical reactions between powder particles, forming materials with specific properties. It is widely used in fields such as electronic ceramics, powder metallurgy, new energy materials (such as lithium battery cathode materials), and specialty ceramics. Roller sintering furnaces, as continuous production equipment, are characterized by high efficiency, low energy consumption, and suitability for large-scale production; however, they have extremely high requirements for the uniformity of raw materials. The uniformity of the raw material's thickness and density directly affects temperature conduction, the consistency of chemical reactions, and product yield during the sintering process.

[0003] Existing roller conveyor sintering furnaces use unautomated production lines for feeding and leveling powder materials. This often requires manual operation, which results in low feeding accuracy, easy overfeeding, and inaccurate powder weight. This affects the quality of the products fired in the sintering furnace. Furthermore, manual operation can lead to powder inhalation, which can negatively impact health over long periods and reduce the efficiency of powder processing.

[0004] Therefore, a feeding and leveling device for roller conveyor sintering furnace is proposed. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a feeding and leveling device for a roller conveyor sintering furnace, which can achieve the following:

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A feeding and leveling device for a roller conveyor sintering furnace includes a conveying platform. Multiple drive rollers are arranged on the inner surface of the conveying platform. An infrared sensor is installed on the upper front surface of the conveying platform, and an infrared sensor is installed on the upper rear surface of the conveying platform. A weighing platform is installed on the bottom surface of the inner wall of the front end of the conveying platform, and a support frame is installed on the upper surface of the weighing platform. A hydraulic jack is fixedly installed through the surface of the support frame, and a top block is installed on the upper surface of the hydraulic jack. A protective cover is installed on the outer surface of the conveying platform, and a sealing cover is installed on the upper front surface of the protective cover.

[0008] Furthermore, a feeding tank is provided on the upper surface of the sealing cover, and a feeding hopper is provided on the lower surface of the feeding tank.

[0009] Furthermore, a servo motor is provided on one side surface of the hopper, and a rotating rod is provided at the output end of the servo motor. A rotating bearing is provided on the outer surface of the end of the rotating rod, and a guide plate is provided on the outer surface of the rotating rod.

[0010] Furthermore, a connecting sleeve is fixedly installed through the upper surface of the sealing cover, and a limiting slide rod is slidably installed on the inner surface of the connecting sleeve, and a buffer pad is provided on the lower surface of the limiting slide rod.

[0011] Furthermore, a damping shock absorber is installed on the upper outer surface of the limiting slide rod, and the damping shock absorber consists of a damping rod, a damping spring, and a damping washer.

[0012] Furthermore, a leveling station is provided on the bottom surface of the inner wall at the rear end of the conveying platform, and drive belts are installed on both sides of the upper surface of the leveling station.

[0013] Furthermore, a guide groove is provided on the upper rear surface of the protective cover, and a helical drive rod is rotatably installed on the inner wall of the guide groove, and a servo motor is provided at the end of the helical drive rod.

[0014] Furthermore, a sliding block is helically mounted on the surface of the helical drive rod, and the outer surface of the sliding block and the inner surface of the guide groove are configured to slide together.

[0015] Furthermore, an electric telescopic rod is provided on the lower surface of the sliding block, and a connecting plate is provided on the lower surface of the electric telescopic rod.

[0016] Furthermore, a limiting slide rod two is slidably installed through the surface of the connecting plate, and a pressure relief spring is provided on the upper outer surface of the limiting slide rod two, and a scraper is provided on the lower surface of the limiting slide rod two.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through the configuration of a conveying platform, drive rollers, infrared sensor one, infrared sensor two, protective cover, weighing platform, support frame, hydraulic jack, top block, sealing cover, feeding tank, and feeding hopper, utilizes infrared sensor one to automatically feed the crucible. When the crucible passes above the hydraulic jack, the jack is activated, causing the top block to contact the bottom of the crucible and lift it to the inner surface of the sealing cover. After sealing, the raw material is automatically fed into the crucible via the feeding hopper. This automatic feeding method increases the powder loading speed while eliminating manual labor and preventing workers from inhaling powder, ensuring production safety. The sealing cover seals the crucible upon entering its inner surface, preventing powder leakage and environmental pollution during feeding. The weighing platform accurately weighs the falling powder, ensuring precise feeding and consistent quality in subsequent sintering furnace processing, thus improving the material yield. 2. This invention, through the configuration of a servo motor, a rotating rod, a rotating bearing, and a guide plate, allows the servo motor to be controlled to rotate intermittently in both forward and reverse directions during material feeding using a hopper. This controls the guide plate mounted on the outer surface of the rotating rod to rotate inside the hopper, achieving angle adjustment and ensuring that the powder falls evenly onto the inner wall of the crucible. This prevents powder from accumulating in one place and affecting the weighing accuracy of the weighing platform. 3. This invention incorporates a buffer pad, a limiting slide rod, a connecting sleeve, and a damping shock absorber. The buffer pad, during the crucible's ascent, contacts the upper surface of the crucible to reduce vibration and impact when the crucible contacts the sealing cover, preventing excessive impact force from damaging the sealing cover. The damping shock absorber, through friction, slows down the buffer pad as it moves upward, further reducing impact. 4. This invention, through the configuration of a leveling station, drive belt, guide groove, servo motor II, spiral drive rod, sliding block, electric telescopic rod, connecting plate, limit slide rod II, pressure relief spring, and scraper, utilizes an infrared sensor II to detect when the crucible moves to the leveling station. The electric telescopic rod below the sliding block then drives the scraper into the crucible. After the scraper contacts the powder, the servo motor II rotates the spiral drive rod, causing the sliding block to slide along the guide groove, thus automatically leveling the powder inside the crucible. This eliminates the need for manual leveling and improves the efficiency of powder leveling. The pressure relief spring ensures that if excessive downward pressure is generated when the scraper contacts the material inside the crucible, its rebound characteristic can cause the scraper to shift, providing pressure relief protection.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please see Figures 1 to 5A feeding and leveling device for a roller conveyor sintering furnace includes a conveying platform 1. Multiple drive rollers 101 are arranged on the inner surface of the conveying platform 1. An infrared sensor 102 is installed on the upper front surface of the conveying platform 1, and an infrared sensor 103 is installed on the upper rear surface of the conveying platform 1. Using this technical solution, the conveying platform 1 can transport the crucible, facilitating powder processing. The infrared sensor 102, when sensing that the crucible has passed above a hydraulic push rod 202, activates the hydraulic push rod 202 to bring the top block 203 into contact with the bottom of the crucible, lifting it to the inner surface of a sealing cover 204. After sealing by the sealing cover 204, the raw material is automatically fed into the crucible via a feeding hopper 206 using a feeding tank 205. This automatic feeding method increases the powder loading speed while eliminating manual labor, preventing workers from inhaling powder during operation, and ensuring production safety.

[0022] A weighing platform 2 is provided on the bottom surface of the inner wall of the front end of the conveying platform 1, and a support frame 201 is provided on the upper surface of the weighing platform 2. By adopting the above technical solution, the falling powder can be accurately weighed through the setting of the weighing platform 2, ensuring the accuracy of powder feeding, ensuring the consistency of the quality produced in the subsequent sintering furnace, and improving the qualification rate of material production.

[0023] A hydraulic push rod 202 is fixedly installed through the surface of the support frame 201, and a top block 203 is provided on the upper surface of the hydraulic push rod 202. By adopting the above technical solution, the crucible can be lifted and lowered to complete the loading of materials through the setting of the hydraulic push rod 202.

[0024] The outer surface of the conveying platform 1 is provided with a protective cover 104, and the upper front surface of the protective cover 104 is provided with a sealing cover 204. By adopting the above technical solution, the sealing cover 204 can seal the crucible when it enters the inner surface of the sealing cover 204, thus preventing the powder from escaping during the feeding process and causing pollution to the environment.

[0025] The upper surface of the sealing cover 204 is provided with a feeding tank 205, and the lower surface of the feeding tank 205 is provided with a feeding hopper 206. By adopting the above technical solution, the powder can be continuously fed into the interior of the crucible through the setting of the feeding tank 205.

[0026] Figure 6As shown, a servo motor 3 is installed on one side surface of the feeding hopper 206, and a rotating rod 301 is installed at the output end of the servo motor 3. A rotating bearing 302 is installed on the outer surface of the end of the rotating rod 301, and a guide plate 303 is installed on the outer surface of the rotating rod 301. With the above technical solution, by setting the guide plate 303, when feeding material using the feeding hopper 206, the servo motor 3 can be controlled to perform intermittent forward and reverse rotation. This allows the guide plate 303 installed on the outer surface of the rotating rod 301 to rotate inside the feeding hopper 206 to achieve the purpose of angle adjustment, so that the powder falls evenly onto the inner wall of the crucible, avoiding the accumulation of powder in one place, which would affect the weighing accuracy of the weighing platform 2. By setting the rotating bearing 302, the wear caused by rotation can be reduced when the rotating rod 301 rotates, and the service life of the rotating rod 301 and the guide plate 303 can be improved.

[0027] Figure 7 As shown, a connecting sleeve 402 is fixedly installed through the upper surface of the sealing cover 204, and a limiting slide rod 401 is slidably installed on the inner surface of the connecting sleeve 402. A buffer pad 4 is provided on the lower surface of the limiting slide rod 401. By adopting the above technical solution, the buffer pad 4 contacts the upper surface of the crucible to reduce the vibration and impact generated when the crucible contacts the sealing cover 204, and avoid the excessive impact force when the crucible rises, which may damage the sealing cover 204.

[0028] A damping shock absorber 403 is installed on the upper outer surface of the limiting slide bar 401. The damping shock absorber 403 is composed of a damping rod, a damping spring and a damping pad. By adopting the above technical solution, the damping shock absorber 403 can reduce the impact by decelerating the buffer pad 4 through friction during its upward movement.

[0029] Figures 8 to 9 As shown, a leveling station 5 is provided on the bottom surface of the inner wall of the rear end of the conveying platform 1, and drive belts 501 are installed on both sides of the upper surface of the leveling station 5. By adopting the above technical solution, the drive belts 501 can be used to push the crucible back into the sintering furnace for processing after the powder inside the crucible has been leveled. After the infrared sensor 103 detects that the crucible has moved to the leveling station 5, the electric telescopic rod 506 below the sliding block 505 will drive the scraper 510 into the crucible. After the scraper 510 contacts the powder, the servo motor 503 can be started to drive the spiral drive rod 504 to rotate, so that the sliding block 505 slides along the guide groove 502 to drive the scraper 510 to automatically level the powder inside the crucible, saving the time of manual leveling and improving the efficiency of powder leveling.

[0030] The upper rear surface of the protective cover 104 is provided with a guide groove 502, and a spiral drive rod 504 is rotatably installed on the inner wall of the guide groove 502. A servo motor 503 is provided at the end of the spiral drive rod 504. By adopting the above technical solution, the spiral drive rod 504 can stably drive the sliding block 505 to slide along the inner surface of the guide groove 502 through the spiral transmission, so that the scraper 510 can perform a leveling operation on the powder inside the crucible.

[0031] The surface of the spiral drive rod 504 is spirally mounted with a sliding block 505, and the outer surface of the sliding block 505 and the inner surface of the guide groove 502 are slidably connected. By adopting the above technical solution, the sliding direction of the sliding block 505 can be limited by the setting of the guide groove 502, so as to avoid it from deviating during the displacement process and affecting the leveling operation of the scraper 510.

[0032] An electric telescopic rod 506 is provided on the lower surface of the sliding block 505, and a connecting plate 507 is provided on the lower surface of the electric telescopic rod 506. A limiting slide rod 508 is slidably installed through the surface of the connecting plate 507, and a pressure relief spring 509 is provided on the upper outer surface of the limiting slide rod 508. A scraper 510 is provided on the lower surface of the limiting slide rod 508. With the above technical solution, by setting the pressure relief spring 509, if the downward pressure generated when the scraper 510 contacts the material inside the crucible is too large, the pressure relief spring 509 can drive the scraper 510 to move by the rebound characteristic, so as to relieve pressure on the scraper 510.

[0033] In operation, after the crucible enters the automated processing flow, it is first placed on the conveyor platform 1. The drive roller 101 of the platform provides stable conveying power to the crucible through continuous rotation, allowing it to move smoothly along the preset track. When the crucible passes through the monitoring area of ​​the infrared sensor 102, the sensor quickly captures the position information of the crucible and transmits the signal to the control system. Upon receiving the signal, the control system immediately triggers the hydraulic push rod 202 to start, driving the top block 203 to move vertically upward. This allows the top block 203 to precisely fit against the bottom of the crucible, slowly raising the crucible with a stable thrust until its top touches the inner surface of the sealing cover 204. During the crucible's ascent, its top first contacts the buffer pad 4. The damping shock absorber 403 above the buffer pad 4 plays a crucial role, generating damping force through friction to effectively slow down the crucible's ascent. As the crucible continues to rise, the buffer pad 4 gradually comes into close contact with the inner surface of the sealing cover 204, forming a reliable sealing structure and creating a good sealing environment for the subsequent raw material feeding process. After sealing, the feeding tank 205 starts working, and the raw material continuously falls into the crucible through the feeding hopper 206. To ensure uniform distribution of the raw material, the servo motor 3 starts synchronously, driving the rotating rod 301 to rotate intermittently in both directions. The guide plate 303 on the outer surface of the rotating rod 301 rotates flexibly within the feeding hopper 206, guiding the falling powder at multiple angles and effectively preventing local accumulation of powder in the crucible. At the same time, the weighing platform 2 monitors the weight of the material in real time. When the preset threshold is reached, the control system quickly instructs the hydraulic push rod 202 to reset, and the crucible falls back to the conveying platform 1 to continue forward conveying. When the crucible moves to leveling station 5, infrared sensor 103 detects the crucible's position and sends a signal back to the control system. The control system then activates the electric telescopic rod 506, driving the scraper 510 to descend vertically. The scraper 510 slowly extends into the crucible and, upon contact with the powder surface, if the electric telescopic rod 506 continues to press down, the pressure relief spring 509 will contract under pressure, causing the scraper 510 to slide along the limiting slide bar 508, thus protecting the scraper 510 from damage. After the electric telescopic rod 506 stops pressing down, servo motor 503 starts, driving the spiral drive rod 504 to rotate, which in turn drives the sliding block 505 to slide smoothly along the guide groove 502, thereby causing the scraper 510 to move horizontally within the crucible and level the powder surface. After the powder leveling process is completed, the electric telescopic rod 506 drives the scraper 510 to reset. At this time, the drive belt 501 starts, transporting the processed crucible to the subsequent sintering furnace to start a new processing stage.

[0034] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
