Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing technology, specifically an automatic weighing and feeding machine for refractory bricks. Background Technology

[0002] Refractory bricks are a type of special ceramic material made from refractory raw materials such as clay, silica, and high-alumina bauxite as the main components, through batching, molding, and high-temperature sintering. They have high refractoriness, excellent high-temperature stability, and mechanical strength. Their core function is to serve as the lining of high-temperature industrial equipment, protecting the main structure of the equipment through heat insulation and resistance to high-temperature erosion. They are an indispensable basic material in high-temperature industrial fields such as metallurgy, building materials, and energy.

[0003] However, in the current refractory brick production process, manual material placement is still the main method for some companies. Manual material placement requires workers to frequently move raw materials and manually fill molds. Moreover, the working environment is often accompanied by high temperature and dust. Workers need to be in close contact with equipment such as presses and heavy molds. This not only leads to high labor intensity, but also long-term exposure to dust environment can easily cause occupational health problems such as respiratory diseases. At the same time, the randomness of manual operation can also cause uneven material placement, affecting the stability of the quality of finished bricks.

[0004] In addition, even if some production lines use mechanically assisted feeding, raw material dust can still easily remain on the surface of the conveyor belt during the operation of the conveyor equipment. This dust will fall into the production area as the conveyor belt moves, causing waste of refractory materials and increasing raw material loss costs. On the other hand, the spread of dust will further deteriorate the workshop working environment and increase the pressure of cleaning and environmental protection.

[0005] Based on this, the present invention provides an automatic weighing and placing machine for refractory bricks to solve the above problems. Utility Model Content

Detailed Implementation

[0029] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 6 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0030] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0031] This utility model relates to an automatic weighing and feeding machine for refractory bricks, comprising a housing 1, which is generally rectangular in shape. A conveyor belt 2 is fixedly installed on the housing 1 to continuously transport raw materials to the processing point. An N-shaped intercepting frame 3 is fixedly installed at the end of the conveyor belt 2, and an intercepting cylinder 4 is fixedly installed on the intercepting frame 3. An intercepting plate 5 is fixedly installed on the output shaft of the intercepting cylinder 4. When the material is delivered to the required amount, the intercepting cylinder 4 extends, driving the intercepting plate 5 downward to cut off the material. A weighing box 6 is fixedly installed on the housing 1 below the conveyor belt 2. The weighing box 6 is hollow inside and open at both the top and bottom. The weighing box 6 is equipped with a weighing system connected to a power supply and a controller. Weighing cylinders 7 are hinged to both sides of the weighing box 6, and weighing plates 8 are hinged to the output ends of the weighing cylinders 7. The upper ends of the weighing plates 8 are rotatably mounted on the weighing box 6. When the material in the weighing box 6 reaches the required weight, the weighing cylinders 7 on both sides of the weighing box 6 change from the initial extended state to the retracted state. When the weighing cylinders 7 retract, they drive the weighing plates 8 to rotate around the weighing box 6, and the weighing plates 8 open to both sides, allowing the material to be fed to the next process. A conveyor belt 2 is connected to a conveyor motor 9, which is connected to a power supply and a controller.

[0032] As an example, a material distribution box 10 corresponding to the weighing box 6 is installed below the weighing box 6. Material distribution cylinders 11 are hinged to both sides of the material distribution box 10. Material distribution plates 12 are hinged to the output ends of the material distribution cylinders 11. The upper ends of the material distribution plates 12 are rotatably mounted on the material distribution box 10. When the material distribution box 10 moves to the designated position, the material distribution cylinders 11 change from the initial extended state to the retracted state. When the material distribution cylinders 11 retract, they drive the material distribution plates 12 to rotate around the material distribution box 10. The material distribution plates 12 then open to both sides, thereby feeding the material into the next process.

[0033] As one embodiment, a sliding frame 13 is slidably mounted on the outside of the fabric box 10 and inside the machine housing 1. The fabric box 10 is fixedly mounted on the sliding frame 13. Mounting frames 14 are fixedly mounted on both sides of the sliding frame 13. Rail wheels 15, which are respectively placed at the upper and lower ends of the sliding frame 13, are rotatably mounted on the mounting frames 14. The mounting frames 14 can drive the fabric box 10 to slide to the processing point along the rail wheels 15. A fabric push rod 16 is fixedly mounted inside the machine housing 1. The fabric push rod 16 is connected to a power supply and a controller. The output end of the fabric push rod 16 is fixedly mounted on the sliding frame 13. When the fabric push rod 16 extends, it can drive the sliding frame 13 to slide synchronously.

[0034] In actual use, in the initial state, the intercepting plate 5 is raised, and both the weighing plate 8 and the material distribution plate 12 are closed. The material distribution box 10 is positioned directly below the weighing box 6. After the controller starts the conveying motor 9, the conveying conveyor belt 2 transports the raw material to the weighing box 6. The weighing system monitors the weight in real time. When the preset value is reached, the controller immediately stops the conveying conveyor belt 2 and controls the intercepting cylinder 4 to extend, driving the intercepting plate 5 to cut off the raw material transport. Subsequently, the weighing cylinder 7 retracts, driving the weighing plate 8 to open to both sides, unloading the material into the lower material distribution box 1. After unloading is completed, the weighing plate 8 is reset, the flow cut-off plate 5 is raised, and the conveyor belt 2 is restarted to prepare for the next round of weighing. Then, the controller controls the material push rod 16 to extend, pushing the sliding frame 13 to drive the material box 10 to slide along the track wheel 15 to the designated processing point. After reaching the point, the material cylinder 11 retracts, driving the material plate 12 to open and put the material into the next process. After the material is put into the next process, the material plate 12 is reset, and the material push rod 16 retracts, so that the material box 10 returns to the weighing box 6. This process effectively improves the material feeding efficiency.

[0035] As an example, an oil spray valve 17 is fixedly installed at one end of the sliding frame 13. The oil spray valve 17 is connected to a power supply and a controller. A sensor 18 is fixedly installed on the sliding frame 13 next to the oil spray valve 17. The sensor 18 can be a limit sensor, a contact sensor, etc. The sensor 18 is connected to a power supply and a controller. When the sliding frame 13 moves the material box 10 to the processing position, the sensor 18 receives a signal. At this time, the oil spray valve 17 sprays oil at the unloading point to prevent the material from sticking together during demolding.

[0036] As an example, a press 19 corresponding to the fabric placing machine is fixedly installed on the side of the machine box 1. The press 19 is equipped with a hydraulic system, which is connected to a power supply and a controller. A rectangular pressing groove 20 is opened on the press 19 for unloading the fabric box 10. A pressing mold 21 is slidably installed above the pressing groove 20. The pressing mold 21 can slide into the pressing groove 20 to compress and shape the material.

[0037] In practical use, the sliding frame 13 drives the material box 10 from below the weighing box 6, and slides along the guide wheel 15 towards the press 19 under the action of the material push rod 16. When the material box 10 moves to directly above the pressing groove 20 of the press 19, the sensor 18 on the sliding frame 13 is triggered and sends a signal to the controller. The controller immediately instructs the oil injection valve 17 to start, spraying grease into the material feeding point in the pressing groove 20. After the oil spraying is completed, the controller controls the material cylinders 11 on both sides of the material box 10 to retract, driving the material plate 12 to move to both sides. Open the press and feed the material into the pressing groove 20 of the press 19. After the material is fed, the material plate 12 is reset and the material box 10 is moved back to the weighing box 6 along with the sliding frame 13. At the same time, the controller starts the hydraulic system of the press 19, which drives the lower pressing mold 21 above the pressing groove 20 to slide down and into the pressing groove 20 to compress and shape the material in the pressing groove 20. After the shaping is completed, the lower pressing mold 21 moves up and resets, waiting for the next material feeding and compression. This process links the material feeding process with the shaping process, effectively reducing labor costs.

[0038] As an example, a feeding cylinder 22 is fixedly installed on the casing 1. The feeding cylinder 22 is hollow inside, and the lower end discharge port is located directly above the conveyor belt 2. A vibration motor 23 is fixedly installed outside the feeding cylinder 22 to continuously vibrate the raw materials inside the feeding cylinder 22 to prevent stratification. A screen 24 is fixedly installed inside the feeding cylinder 22 to screen large pieces of material. A stirring shaft 25 is rotatably installed inside the feeding cylinder 22 to continuously stir the material inside the feeding cylinder 22 to prevent accumulation. The stirring shaft 25 is connected to a stirring motor 26. Both the vibration motor 23 and the stirring motor 26 are connected to a power supply and a controller.

[0039] As one embodiment, a raw material cylinder 27 is fixedly installed on the side of the casing 1. The raw material cylinder 27 is filled with raw material. A support frame 28 is fixedly installed on the raw material cylinder 27. The support frame 28 is fixedly installed outside the discharge port on the raw material cylinder 27 by two support rods. A feeding conveyor belt 29 is fixedly installed on the support frame 28. The raw material can be transported to the feeding cylinder 22 through the feeding conveyor belt 29. Baffles 30 are fixedly installed on both sides of the feeding conveyor belt 29 to prevent the material from spilling from both sides of the feeding conveyor belt 29. The feeding conveyor belt 29 is connected to a feeding motor 31. The feeding motor 31 is connected to a power supply and a controller.

[0040] As an example, a sealing plate 32 is slidably installed outside the discharge port of the raw material cylinder 27 to block the raw material inside the raw material cylinder 27. A feeding push rod 33 is fixedly installed on the support frame 28. The feeding push rod 33 is connected to a power supply and a controller. The output end of the feeding push rod 33 is connected to the sealing plate 32, so that the feeding push rod 33 can drive the sealing plate 32 to open and close up and down, thereby blocking the discharge port.

[0041] In practical use, initially, the sealing plate 32 of the raw material cylinder 27 is closed, preventing the raw material from falling. After the controller is started, it first controls the feeding push rod 33 to retract, causing the sealing plate 32 to slide upward and open the discharge port of the raw material cylinder 27. At the same time, the feeding motor 31 is started to drive the feeding conveyor belt 29 to rotate. The raw material falls from the raw material cylinder 27 into the feeding conveyor belt 29 and is conveyed into the feeding cylinder 22 under the obstruction of the side baffles 30. After the raw material enters the feeding cylinder 22, the controller simultaneously starts the stirring motor 26 and the vibration motor 23, and the stirring shaft 2... Driven by the stirring motor 26, the material continuously rotates to stir the raw materials and prevent them from accumulating and clumping. The vibrating motor 23 causes the feeding cylinder 22 to vibrate as a whole, which, together with the stirring action, ensures that the raw materials are evenly distributed and avoids stratification due to density differences. At the same time, the screen 24 inside the feeding cylinder 22 screens the raw materials, intercepting large impurities or undissolved clumps of material, ensuring that the raw materials falling into the next process have uniform particle size. After being screened, stirred and vibrated, the raw materials fall from the discharge port at the lower end of the feeding cylinder 22 onto the conveyor belt 2 and enter the subsequent processing steps.

[0042] As an example, a scraper 34 is provided below the end of the feeding conveyor belt 29. The scraper 34 is arc-shaped and is rotatably mounted on the support frame 28. A circumferential pin 35 is fixedly installed on both sides of the scraper 34. Arc-shaped grooves 36 for sliding of the pins 35 are provided on both sides of the support frame 28. Sleeves 37 corresponding to the pins 35 are fixedly installed on both sides of the support frame 28. The same tension spring 38 is fixedly sleeved on the pins 35 and the sleeves 37. The tension spring 38 is always in a stretched state and generates tension on the pins 35, so that the scraper 34 is always in contact with the surface of the feeding conveyor belt 29 and scrapes the surface of the feeding conveyor belt 29. This process effectively avoids the technical problem of some raw materials spilling.

[0043] As an example, a dustproof plate 39 is fixedly installed around the upper end of the feeding cylinder 22 to block the dust generated by the raw materials falling from the feeding conveyor belt 29 into the feeding cylinder 22.

[0044] The working principle of this utility model is as follows: In the initial state, the sealing plate 32 of the raw material cylinder 27 is closed, the feeding and conveying conveyor belt 2 stops rotating, the weighing plate 8 and the material distribution plate 12 are closed, and the material distribution box 10 is located directly below the weighing box 6. After the controller is started, the feeding push rod 33 on the support frame 28 next to the raw material cylinder 27 is first controlled to retract, which drives the sealing plate 32 to slide up and open the discharge port. At the same time, the feeding motor 31 is started to drive the feeding conveyor belt 29 to rotate. The baffles 30 on both sides of the conveyor belt prevent the raw material from spilling. The arc-shaped scraper 34 at the end scrapes off the residual raw material on the belt surface and smoothly conveys the raw material to the feeding cylinder 22.

[0045] After the raw material enters the feeding cylinder 22, the controller simultaneously starts the stirring motor 26 and the vibration motor 23. The screen 24 inside the feeding cylinder 22 intercepts large impurities, and the dustproof plate 39 at the top blocks dust. The pre-treated raw material falls from the bottom outlet of the feeding cylinder 22 onto the conveyor belt 2 on the machine box 1.

[0046] The material conveying motor 9 drives the conveyor belt to feed the material to the end. The material falls into the weighing box 6 below. The weighing system in the weighing box 6 monitors the weight in real time. When the preset value is reached, the controller stops the material conveying motor 9 and at the same time controls the intercepting cylinder 4 on the intercepting frame 3 to extend, driving the intercepting plate 5 to move down and cut off the material conveying. Then the weighing cylinders 7 on both sides of the weighing box 6 retract, driving the weighing plate 8 to open and unload the material into the material distribution box 10 below.

[0047] Next, the controller starts the fabric push rod 16 inside the machine box 1, which pushes the sliding frame 13 to move the fabric box 10 to the side press 19. When the sensor 18 on the sliding frame 13 detects that the fabric box 10 has reached the top of the pressing groove 20 of the press 19, it immediately sends a signal to the controller. The controller instructs the oil spray valve 17 at one end of the sliding frame 13 to start and spray oil into the material feeding point in the pressing groove 20 to prevent sticking.

[0048] After the oil spraying is completed, the material cylinders 11 on both sides of the material box 10 retract, causing the material plate 12 to open and feed the raw material into the pressure groove 20. Then the controller starts the hydraulic system in the press 19, driving the lower pressing mold 21 above the pressure groove 20 to slide down and slide into the pressure groove 20 to compress and shape the raw material. After the shaping is completed, the hydraulic system drives the lower pressing mold 21 to move up and reset, waiting for the next batch of raw material to be fed.

[0049] The present invention has the following technical effects.

[0050] 1. By incorporating a material conveyor belt 2, a weighing box 6, and a flow interceptor 3, this utility model enables the material conveyor belt 2 to continuously transport raw materials, the flow interceptor cylinder 4 to drive the flow interceptor plate 5 to cut off the excess material, and the material distribution push rod 16 to drive the material distribution box 10 to slide to the processing point, thus significantly improving the overall material distribution efficiency.

[0051] 2. This utility model achieves continuous material conveying by adding a feeding conveyor belt 29, baffles 30, scrapers 34, etc., while the baffles 30 on both sides prevent material spillage. The tension spring 38 pulls the scraper 34 to always be in contact with the belt surface to scrape off residue, eliminating the need for manual cleaning of the conveyor belt and reducing material spillage.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
