Description

Technical Field

[0001] This utility model belongs to the technical field of aerated concrete block production equipment, specifically a feeding device for the production of autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks, or simply AAC blocks, are aerated concrete blocks produced using a high-temperature autoclaving process. AAC blocks are characterized by their light weight, good thermal insulation, strong earthquake resistance, good processing performance, certain high-temperature resistance, good sound insulation, and strong adaptability.

[0003] During the production of aerated concrete blocks, the mixed slurry needs to be poured into the mold. When unloading, workers need to level the surface of the slurry in the mold, which is time-consuming and labor-intensive and affects the processing speed.

[0004] Therefore, this utility model provides a feeding device for the production of autoclaved aerated concrete bricks. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A feeding device for the production of autoclaved aerated concrete bricks, comprising a support frame; grooves are provided on both sides of the support frame, and a sliding rod is slidably connected within the grooves; a servo motor is fixedly connected to the middle of the sliding rod, and a threaded rod is fixedly connected to the bottom of the servo motor; a push plate is threadedly connected to the outer side of the threaded rod; a scraper is provided at the bottom of the push plate; a spring is fixedly connected to one side of the scraper, and a mold block is fixedly connected to one end of the spring; during operation, slurry falls into the mold block, at which point the servo motor is activated, and the rotation of the servo motor drives the threaded rod to rotate. The push plate descends under the drive of the threaded rod, and the descending push plate contacts the scraper, causing it to squeeze. The scraper is pushed forward by the force, thus achieving the effect of smoothing the surface of the slurry. At this time, the servo motor rotates in the reverse direction, and the push plate moves upward under the action of the threaded rod. The scraper gradually loses its pushing force and resets under the action of the spring. After that, the servo motor rotates in the forward direction again, driving the push plate to apply pushing force to the scraper, smoothing the surface of the slurry again, and then resets. This cycle repeats until the material is finished, and the surface of the slurry in the mold block tends to be at the same horizontal line. By adjusting the position of the slide rod in the groove, the surface of the slurry at different heights can be smoothed.

[0007] Preferably, a support rod is fixedly connected to the top of the scraper, and cleaning rods are fixedly connected to both ends of the support rod. During operation, the scraper is subjected to the pushing force and unloading force of the push plate and reciprocates within the mold block. The support rod moves with the scraper, and the cleaning rods approach the outer wall of the mold block. When the scraper moves, the cleaning rods clean the outer wall of the mold block. This can reduce the adhesion of slurry to the outer wall of the mold block during material feeding, making it easier to clean the mold block subsequently.

[0008] Preferably, multiple hollow blocks are fixedly connected to both sides of the mold block, and steel balls are movably installed inside the hollow blocks. During operation, when the cleaning rod reciprocates outside the mold block, the cleaning rod will touch the hollow blocks, causing the steel balls inside the hollow blocks to shake, which in turn will strike the mold block, causing the mold block to vibrate. This arrangement can accelerate the movement of the slurry inside the mold block, expel the air in the slurry, and make the slurry evenly fill the mold block.

[0009] Preferably, the spring is provided with an elastic cloth on its outer side. One end of the elastic cloth is fixedly connected to the scraper, and the other end of the elastic cloth is fixedly connected to the mold block. During operation, the scraper is pushed and the spring undergoes elastic deformation. The elastic cloth deforms along with the spring. The elastic cloth can protect the spring from being contaminated by the slurry during feeding and ensure that the spring can operate normally.

[0010] Preferably, the mold block is provided with a storage groove on the outside, and the storage groove is fixedly connected to the mold block. During operation, the cleaning rod cleans the outside of the mold block, and the scraped slurry will fall into the storage groove, which facilitates the recycling and reuse of the slurry.

[0011] Preferably, sponge blocks are provided on both sides of the scraper, and the sponge blocks are fixedly connected to the scraper. During operation, the sponge blocks are close to the inner wall of the mold block. When the scraper moves, it will drive the sponge blocks to wipe the inner wall of the mold block and wipe the slurry adhering to the inner wall of the mold block, so that it falls into the mold block and mixes with other slurries. This not only cleans the inner wall of the mold block, but also reduces the waste of slurry.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The feeding device for the production of autoclaved aerated concrete bricks described in this utility model is configured to push a scraper downward by a pusher plate. The rotation of a servo motor drives the threaded rod to rotate, causing the pusher plate to move downward. The pusher plate pushes the scraper plate, allowing the scraper plate to move on the surface of the slurry, so as to achieve the purpose of the scraper plate leveling the slurry. The servo motor reverses, so that the scraper plate is reset under the action of the spring. During this process, the scraper plate performs scraping operation on the surface of the slurry again.

[0014] 2. The feeding device for autoclaved aerated concrete brick production described in this utility model, by setting up hollow blocks and steel balls, when the cleaning rod reciprocates on the outside of the mold block, the cleaning rod will touch the hollow block, causing the steel ball inside the hollow block to shake, which in turn will knock on the mold block, causing the mold block to vibrate; this setting can accelerate the movement of slurry in the mold block, expel the air in the slurry, and make the slurry evenly fill the mold block.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4As shown in the embodiment of this utility model, a feeding device for the production of autoclaved aerated concrete bricks includes a support frame 1. Grooves 11 are provided on both sides of the support frame 1. A sliding rod 12 is slidably connected within the grooves 11. A servo motor 13 is fixedly connected to the middle of the sliding rod 12. A threaded rod 14 is fixedly connected to the bottom of the servo motor 13. A push plate 15 is threadedly connected to the outer side of the threaded rod 14. A scraper 16 is provided at the bottom of the push plate 15. A spring 17 is fixedly connected to one side of the scraper 16. A mold block 18 is fixedly connected to one end of the spring 17. By setting the push plate 15 to press the scraper 16 downwards, the servo motor 13 rotates, driving the threaded rod 14 to rotate, causing the push plate 15 to move downwards. The push plate 15 pushes the scraper 16, allowing the scraper 16 to move on the surface of the slurry, achieving the purpose of leveling the slurry. The servo motor 13 reverses, causing the scraper 16 to reset under the action of the spring 17. During this process, the scraper 16 performs another scraping operation on the slurry surface.

[0024] like Figures 1 to 4 As shown, a support rod 2 is fixedly connected to the top of the scraper 16, and cleaning rods 21 are fixedly connected to both ends of the support rod 2. The scraper 16 is subjected to the pushing force and unloading force of the push plate 15 and reciprocates within the mold block 18. The support rod 2 moves with the scraper 16, and the cleaning rods 21 approach the outer wall of the mold block 18. When the scraper 16 moves, the cleaning rods 21 clean the outer wall of the mold block 18. This can reduce the adhesion of slurry to the outer wall of the mold block 18 during material feeding, making it easier to clean the mold block 18 subsequently.

[0025] like Figures 1 to 5 As shown, multiple hollow blocks 3 are fixedly connected to both sides of the mold block 18. Steel balls 31 are movably disposed inside the hollow blocks 3. When the cleaning rod 21 reciprocates outside the mold block 18, the cleaning rod 21 will touch the hollow block 3, causing the steel balls 31 inside the hollow block 3 to shake, which in turn will strike the mold block 18, causing the mold block 18 to vibrate. This arrangement can accelerate the movement of the slurry inside the mold block 18, expel the air in the slurry, and make the slurry fill the mold block 18 evenly.

[0026] like Figures 1 to 4 As shown, an elastic cloth 4 is provided on the outside of the spring 17. One end of the elastic cloth 4 is fixedly connected to the scraper 16, and the other end of the elastic cloth 4 is fixedly connected to the mold block 18. When the scraper 16 is pushed, the spring 17 undergoes elastic deformation, and the elastic cloth 4 deforms along with the spring 17. The elastic cloth 4 can protect the spring 17 from being contaminated by the slurry during feeding, and protect the spring 17 so that it can operate normally.

[0027] like Figures 1 to 4As shown, the mold block 18 is provided with a storage groove 5 on the outside. The storage groove 5 is fixedly connected to the mold block 18. The cleaning rod 21 cleans the outside of the mold block 18. The scraped slurry will fall into the storage groove 5, which makes it easy to recycle and reuse the slurry.

[0028] like Figures 1 to 4 As shown, sponge blocks 6 are provided on both sides of the scraper 16. The sponge blocks 6 are fixedly connected to the scraper 16. The sponge blocks 6 are close to the inner wall of the mold block 18. When the scraper 16 moves, it will drive the sponge blocks 6 to wipe the inner wall of the mold block 18 and wipe the slurry adhering to the inner wall of the mold block 18, so that it falls into the mold block 18 and mixes with other slurries. This not only cleans the inner wall of the mold block 18, but also reduces the waste of slurry.

[0029] Working principle: When the slurry falls into the mold block 18, the servo motor 13 is activated. The rotation of the servo motor 13 drives the threaded rod 14 to rotate, and the push plate 15 descends under the action of the threaded rod 14. The descending push plate 15 contacts the scraper 16 and squeezes it. The scraper 16 is pushed forward by the force, thereby achieving the effect of smoothing the surface of the slurry. Then the servo motor 13 rotates in the reverse direction, and the push plate 15 moves upward under the action of the threaded rod 14. The scraper 16 gradually loses its pushing force and resets under the action of the spring 17. After that, the servo motor 13 rotates in the forward direction again, driving the push plate 15 to move against the scraper. 16. Apply a pushing force to level the slurry surface again, then reset, repeating this cycle until the slurry surface inside the mold block 18 is at a similar horizontal level. Adjusting the position of the slide rod 12 within the groove 11 allows for leveling of slurry surfaces at different heights. The scraper 16, subjected to the pushing and unloading forces of the push plate 15, reciprocates within the mold block 18. The support rod 2 moves with the scraper 16, and the cleaning rod 21 approaches the outer wall of the mold block 18. As the scraper 16 moves, the cleaning rod 21 cleans the outer wall of the mold block 18. This reduces the time required for slurry feeding. The adhesion of the slurry to the outer wall of the mold block 18 facilitates subsequent cleaning of the mold block 18. When the cleaning rod 21 reciprocates on the outside of the mold block 18, the cleaning rod 21 will touch the hollow block 3, causing the steel ball 31 inside the hollow block 3 to shake, which in turn will knock on the mold block 18, causing the mold block 18 to vibrate. This arrangement can accelerate the movement of the slurry inside the mold block 18, expel the air in the slurry, and make the slurry fill the mold block 18 evenly. The scraper 16 is pushed by the spring 17 to undergo elastic deformation, and the elastic cloth 4 deforms with the spring 17. 4 can protect the spring 17 from being contaminated by the slurry during feeding, ensuring the normal operation of the spring 17. The cleaning rod 21 cleans the outside of the mold block 18, and the scraped slurry will fall into the collection tank 5, which facilitates the recycling and reuse of the slurry. The sponge block 6 is close to the inner wall of the mold block 18. When the scraper 16 moves, it will drive the sponge block 6 to wipe the inner wall of the mold block 18, wiping away the slurry contaminated on the inner wall of the mold block 18, causing it to fall into the mold block 18 and mix with other slurries. This not only cleans the inner wall of the mold block 18, but also reduces the waste of slurry.
