Description

Technical Field

[0001] This utility model relates to the field of amorphous material spraying adjustment technology, specifically an amorphous material spraying adjustment mechanism. Background Technology

[0002] Amorphous materials are solid materials with disordered atomic arrangement and no long-range periodicity of crystal structure. They are also known as metallic glasses. They are formed by rapidly cooling molten metal or alloy to suppress the regular arrangement of atoms into crystals, thus forming an amorphous structure similar to glass. Due to their unique properties, amorphous materials are widely used in industrial fields. In the production of amorphous thin strips, spraying is the core component of molten metal spraying.

[0003] The existing amorphous material spraying adjustment mechanism first fixes the spraying bag inside the spraying machine with a support frame, so that the outlet of the spraying bag is directly above the cooling roller. Then, the molten amorphous material in the crucible is poured into the spraying bag and sprayed through the nozzle to the outside of the cooling roller, so that the amorphous material cools down and solidifies rapidly. After being scraped off by a scraper, when there is a need to produce amorphous thin strips of different widths, the equipment is stopped and the operator manually rotates the dial to rotate the screws on both sides (clockwise or counterclockwise), pushing or pulling the baffle to move horizontally, directly changing the nozzle width.

[0004] Existing amorphous material spraying adjustment mechanisms require machine shutdown and rely on manual rotation of the dial, which cannot meet the needs of rapid changeover in continuous production. Manual operation makes it difficult to ensure the synchronization of the screws on both sides, which can easily lead to baffle tilting and uneven nozzle width. Therefore, we propose an amorphous material spraying adjustment mechanism. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an amorphous material spraying adjustment mechanism that can achieve precise synchronous adjustment of the baffle position, avoid subjective errors of manual operation, reduce manual intervention, reduce the risk of operational errors, and ensure production stability and safety. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an amorphous material spraying adjustment mechanism, including a bracket, wherein a spraying bag is provided inside the bracket, and a nozzle width adjustment mechanism is also included;

[0007] Nozzle width adjustment mechanism: It includes guide groove, baffle, slide groove, slide column, connecting rod and connecting block. The bottom end of the spray bag is provided with guide grooves on the front and rear inner walls respectively. The two guide grooves are slidably connected with symmetrically distributed baffles. The front side of the baffle is provided with a slide column near the center of the spray bag. The bottom side of the front side of the spray bag is provided with a slide groove corresponding to the slide column. The outside of the slide column is slidably connected to the inside of the longitudinally adjacent slide groove. The front end of the slide column is rotatably connected with a connecting rod. The two connecting rods are rotatably connected to the inside of a connecting block near the center of the spray bag. It realizes precise synchronous adjustment of the baffle position, avoids subjective error of manual operation, reduces manual intervention, reduces the risk of operation error, and ensures production stability and safety.

[0008] Furthermore, a microcontroller is installed on the outside of the bracket, and the input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0009] Furthermore, the nozzle width adjustment mechanism also includes a telescopic plate, which is fixedly connected between two baffles on the same side. The upper and lower sides of the telescopic plate are in contact with the upper and lower inner walls of the guide groove to prevent amorphous materials from entering the guide groove.

[0010] Furthermore, the nozzle width adjustment mechanism also includes an electric push rod, which is located at the bottom of the front side of the spray pack. The telescopic end of the electric push rod is fixedly connected to the top of the connecting block, and the input end of the electric push rod is electrically connected to the output end of the microcontroller to provide adjustment drive.

[0011] Furthermore, the upper end of the bracket is provided with grooves, and a support plate is fixedly sleeved on the upper outer end of the spray bag. The bottom ends of the front and rear sides of the support plate are slidably connected to the inside of the grooves. A guide rod is provided between the left and right inner walls of the rear groove. The bottom end of the rear side of the support plate is slidably connected to the outside of the guide rod. A screw is rotatably connected between the left and right inner walls of the front groove. The bottom end of the front side of the support plate is threadedly connected to the screw, thereby realizing the adjustment of the spray bag position.

[0012] Furthermore, corrugated tubes are provided between the left and right sides of the front end of the support plate and the left and right inner walls of the groove on the front side, and the lead screw is located inside the corrugated tubes to prevent impurities from affecting the transmission of precision components.

[0013] Furthermore, a motor is provided at the front left side of the bracket. The right end of the motor's output shaft is fixedly connected to the left end of the lead screw, and the input end of the motor is electrically connected to the output end of the microcontroller to provide spray pack position adjustment.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This amorphous material spraying adjustment mechanism has the following advantages:

[0015] The electric push rod drives the connecting block to move up and down, and the connecting rod drives the sliding column to slide inside the slide groove. When the two side baffles move towards the center, the nozzle width narrows, and when the baffles move to the sides, the nozzle width widens, thus realizing the adjustment of the spray bag nozzle width. The electric push rod drives the connecting rod mechanism to move the two side baffles synchronously. Compared with the manual adjustment of the transmission, it can greatly shorten the adjustment time and accurately adjust the baffle position, ensuring the stability of production and the safety of personnel.

[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 1-4This embodiment provides a technical solution: an amorphous material spraying adjustment mechanism, including a bracket 1, a spraying bag 2 inside the bracket 1, and a nozzle width adjustment mechanism 6. A microcontroller 5 is installed outside the bracket 1, and the input end of the microcontroller 5 is electrically connected to an external power supply. Grooves 4 are respectively opened on the upper end of the bracket 1. A support plate 3 is fixedly sleeved on the upper end of the spraying bag 2. The bottom ends of the front and rear sides of the support plate 3 are slidably connected to the inside of the grooves 4. A guide rod 7 is provided between the left and right inner walls of the rear groove 4. The bottom end of the rear side of the support plate 3 is slidably connected to the outside of the guide rod 7. A lead screw 8 is rotatably connected between the left and right inner walls of the front groove 4. The bottom end of the front side of the support plate 3 is threadedly connected to the lead screw 8. Corrugated tubes 9 are provided between the left and right sides of the front end of the support plate 3 and the left and right inner walls of the front groove 4. The lead screw 8 is located inside the corrugated tubes 9. A motor 10 is provided at the front left side of the bracket 1. The right end of the output shaft of motor 10 is fixedly connected to the left end of lead screw 8. The input end of motor 10 is electrically connected to the output end of microcontroller 5. When the amorphous material spraying machine needs to use spray bag, the spray bag 2 is first fixed to the inside of the spraying machine through bracket 1 so that the nozzle at the bottom of the spray bag 2 is directly above the cooling roller. Then, through the control of microcontroller 5, motor 10 starts to run, and the output shaft drives lead screw 8 to start to rotate. The threaded support plate 3 drives the spray bag 2 to slide under the guidance of guide rod 7. The corrugated pipe 9 between the front end of support plate 3 and the inner wall of groove 4 moves with support plate 3 and extends and retracts, covering lead screw 8 to prevent amorphous material or dust from entering the transmission mechanism of lead screw 8. The spray bag 2 is adjusted to a suitable position. Then, the amorphous material melted inside the crucible is poured into the inside of spray bag 2 and sprayed through the outlet of spray bag 2 onto the high-speed rotating cooling roller. Then, the solidified amorphous material on the cooling roller is scraped off by scraper.

[0023] Nozzle width adjustment mechanism 6: It includes guide groove 61, baffle 62, slide groove 63, slide column 64, connecting rod 65, and connecting block 66. Guide groove 61 is provided on the front and rear inner walls of the bottom end of the spray bag 2. Baffle 62 is symmetrically distributed between the two guide grooves 61. Slide column 64 is provided on the front side of the baffle 62 near the center of the spray bag 2. Slide groove 63 corresponding to slide column 64 is provided on the bottom of the front side of the spray bag 2. The outside of the slide column 64 is slidably connected to the inside of the longitudinally adjacent slide groove 63. The front end of the slide column 64 is rotatably connected to the connecting rod 66. 5. The ends of the two connecting rods 65 near the center of the spray pack 2 are rotatably connected to the inside of a connecting block 66. The nozzle width adjustment mechanism 6 also includes a telescopic plate 67, which is fixedly connected between two baffles 62 on the same side. The upper and lower sides of the telescopic plate 67 are in contact with the upper and lower inner walls of the guide groove 61. The nozzle width adjustment mechanism 6 also includes an electric push rod 68, which is located at the bottom of the front side of the spray pack 2. The telescopic end of the electric push rod 68 is fixedly connected to the top of the connecting block 66. The input end of the electric push rod 68 is electrically connected to the output end of the microcontroller 5. When producing thin strips of different widths, the electric push rod 68 starts operating under the control of the microcontroller 5. The telescopic end of the electric push rod 68 drives the connecting block 66 to move up and down. When the electric push rod 68 extends, the connecting block 66 moves downward, driving the sliding column 64 to slide towards the center along the sliding groove 63 via the connecting rod 65. When the electric push rod 68 retracts, the connecting block 66 moves upward, driving the sliding column 64 to slide to both sides along the sliding groove 63 via the connecting rod 65. When the baffles 62 on both sides move towards the center, the nozzle width decreases; when the baffles 62 move to both sides, the nozzle width increases, thus limiting the spray. The spray width of package 2 is such that when the two baffles 62 move, the telescopic plate 67 between the two baffles 62 on the same side extends or compresses with the movement of the baffles 62 (the telescopic plate 67 is composed of a first plate, a second plate that is slidably connected in the inner sliding opening of the first plate, and a third plate that is slidably connected between the inner sliding openings of the two second plates, and the upper and lower sides of the first plate, the second plate and the third plate are slidably connected to the inner wall of the guide groove 61, which can effectively prevent amorphous materials from entering the interior of the guide groove 61. After a long period of time and a large amount of accumulation, the baffle 62 is easily jammed and cannot slide).

[0024] The working principle of the amorphous material spraying adjustment mechanism provided by this utility model is as follows: When the amorphous material spraying machine needs to use a spraying bag, the spraying bag 2 is first fixed inside the spraying machine by the bracket 1, so that the nozzle at the bottom of the spraying bag 2 is directly above the cooling roller. Then, through the control of the microcontroller 5, the motor 10 starts to run, and the output shaft drives the lead screw 8 to start rotating, so that the threaded support plate 3 drives the spraying bag 2 to slide under the guidance of the guide rod 7. The corrugated tube 9 between the front end of the support plate 3 and the inner wall of the groove 4 extends and retracts with the movement of the support plate 3, covering the lead screw 8 to prevent amorphous material or dust from entering the transmission mechanism of the lead screw 8, so that the spraying bag 2 is adjusted to a suitable position. Then, the amorphous material molten inside the crucible is poured into the interior of the spraying bag 2 and sprayed onto the high-speed rotating cooling roller through the outlet of the spraying bag 2. Then, the solidified amorphous material on the cooling roller is scraped off by the scraper. When facing the production of thin strips of different widths, through the control of the microcontroller 5, the electric push rod 68 starts to run. The extension and retraction end of the electric push rod 68 will drive the connecting block 66. When the electric push rod 68 extends, the connecting block 66 moves downward, driving the sliding column 64 to slide towards the center along the sliding groove 63 via the connecting rod 65. When the electric push rod 68 retracts, the connecting block 66 moves upward, driving the sliding column 64 to slide towards both sides along the sliding groove 63 via the connecting rod 65. When the two side baffles 62 move towards the center, the nozzle width decreases. When the baffles 62 move towards both sides, the nozzle width increases, thereby limiting the spray width of the spray bag 2. When the two baffles 62 move, the telescopic plate 67 between the two baffles 62 on the same side extends or compresses with the movement of the baffles 62. (The telescopic plate 67 is composed of a first plate, a second plate that is slidably connected in the inner sliding port one of the first plate, and a third plate that is slidably connected between the inner sliding ports two of the two second plates. The upper and lower sides of the first plate, the second plate, and the third plate are all slidably connected to the inner wall of the guide groove 61, which can effectively prevent amorphous materials from entering the interior of the guide groove 61. After a long period of accumulation, the baffle 62 is prone to jamming and cannot slide).

[0025] It is worth noting that the microcontroller 5 disclosed in the above embodiments can be an STM32F103RB, the motor 10 can be a BMR-50, and the electric actuator 68 can be a DYTP. The microcontroller 5 controls the operation of the motor 10 and the electric actuator 68 using methods commonly used in the prior art.
