Description

Technical Field

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

[0002] The molding of autoclaved aerated concrete (AAC) blocks is a systematic and precise process. First, siliceous materials (such as fly ash and sand) and calcareous materials (such as cement and lime) are used as core raw materials, along with auxiliary materials such as a foaming agent (commonly aluminum powder). These are mixed in strict proportions to form a uniform slurry, ensuring the slurry has suitable fluidity to meet the requirements of subsequent processes. Next, the slurry is poured into molds. At 50-80℃, the foaming agent reacts chemically with the calcareous materials, releasing hydrogen gas, causing the slurry to expand uniformly and fill the mold. After a static curing phase, the slurry solidifies and hardens to form a green body with a certain strength. After demolding, it is cut into blocks of the designed specifications. Finally, the blocks are placed in an autoclave and cured in a steam environment at 170-200℃ and 0.8-1.5MPa pressure. This promotes deep hydration reactions between the raw materials, generating stable cementitious substances, ultimately forming lightweight, high-strength, porous high-quality blocks. Throughout the entire process, the process parameters at each stage must be precisely controlled to ensure the quality and performance of the blocks.

[0003] For example, patent CN119610420A discloses a liftable water quality monitoring buoy, including a float that can be suspended on aquaculture water. A cavity is provided inside the buoy, and a guide cylinder is installed inside the cavity. The top of the guide cylinder communicates with the cavity, and the bottom of the guide cylinder communicates with the outside. A water quality sensor is installed inside the guide cylinder, and a lifting motor is installed inside the cavity. The lifting motor is linked to a connecting mechanism via a lifting shaft. One end of the connecting mechanism is fixedly connected to the lifting shaft, and the other end is connected to the water quality sensor. The water quality sensor can move up and down along the inner wall of the guide cylinder under the drive of the lifting motor and the connecting mechanism. However, in the use of existing devices, the concrete blocks are prone to positional displacement during edge cutting, leading to a chain reaction of poor edge cutting accuracy and dimensional defects, affecting product quality. Furthermore, the edge cutting process is slow and inefficient, making it difficult to meet the demands of high-efficiency production. At the same time, a large amount of dust is generated during the cutting operation, polluting the environment and adversely affecting the cleanliness of the production site and the working conditions of the operators.

[0004] Therefore, in order to solve such problems, we propose a cutting device for forming autoclaved aerated concrete blocks. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting device for forming autoclaved aerated concrete blocks, in order to solve the problems mentioned in the background art. When using the existing device, the concrete blocks are prone to positional displacement during cutting, which leads to a chain reaction of poor cutting accuracy and unqualified dimensions, affecting product quality. In addition, the cutting process is slow and inefficient, making it difficult to meet the needs of high-efficiency production. At the same time, a large amount of dust is generated during the cutting operation, which not only pollutes the environment but also has an adverse effect on the cleanliness of the production site and the working conditions of the operators.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for forming autoclaved aerated concrete blocks, comprising a base, with first grooves on both sides of the top of the base, a double-threaded rod rotatably connected in the first groove, a first motor fixedly connected to the right end of the double-threaded rod, a first slider threadedly connected to the double-threaded rod, a side plate fixedly connected to the top of the first slider, a first buffer spring evenly fixedly connected to the inner wall of the side plate, a support plate fixedly connected to the side of the first buffer spring away from the side plate, a second groove on the side of the support plate away from the first buffer spring, a sliding rod fixedly connected in the second groove, a second slider movably connected to both ends of the outer wall of the sliding rod, and a protective spring movably sleeved on the outer wall of the sliding rod, and a limit plate fixedly connected to the outer end of the second slider.

[0007] Furthermore, a second motor is fixedly connected to the middle of the bottom surface of the base, and a rotating shaft is fixedly connected to the output end of the second motor. The rotating shaft passes through the middle of the base, and a turntable is fixedly connected to the top of the rotating shaft.

[0008] Furthermore, both sides of the top of the base are fixedly connected to fasteners. A third motor is fixedly connected to the outer wall of the right fastener on the top of the base. A rotating rod is fixedly connected to the output end of the third motor. A rotating disk is fixedly connected to the left side of the rotating rod. An eccentric bolt is fixedly connected to the side of the rotating disk away from the rotating rod. A transmission rod is movably connected to the eccentric bolt. A U-shaped piece is movably connected to the bottom of the transmission rod. A U-shaped frame is fixedly connected to the bottom of the U-shaped piece.

[0009] Furthermore, a second buffer spring is fixedly connected to the bottom of the U-shaped frame, a fixed plate is fixedly connected to the bottom of the second buffer spring, and a cutter is fixedly connected to the middle of the bottom surface of the fixed plate.

[0010] Furthermore, a third sliding groove is provided on the inner wall of the fixing member, and a third slider is fixedly connected to the outer walls on both sides of the U-shaped frame, and the fixing member and the U-shaped frame are slidably connected through the third sliding groove.

[0011] Furthermore, a fourth sliding groove is provided on the inner wall of the U-shaped frame, and a fourth slider is fixedly connected to the outer walls on both sides of the fixed plate. The U-shaped frame and the fixed plate are slidably connected through the fourth sliding groove and the fourth slider.

[0012] Furthermore, a connecting rod is fixedly connected to the rear of the top right side plate of the base, and a plunger is fixedly connected to the connecting rod. A tank is fixedly connected to the rear of the top side plate of the base, and the plunger is located inside the tank. A nozzle is fixedly connected to the front outer wall of the tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are: a cutting device for forming autoclaved aerated concrete blocks adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The cutting device for forming autoclaved aerated concrete blocks can precisely adjust the distance between the two side plates through the threaded engagement of the double threaded rod and the first slider, adapting to concrete blocks of different specifications. The first buffer spring on the inner wall of the side plate can provide buffering to prevent the block from being damaged due to excessive rigidity when clamping the block. At the same time, the sliding rod, the second slider and the protective spring on the support plate drive the limiting plate to further clamp the block from both sides. Even if there are slight differences in the size of the block, the elasticity of the protective spring can ensure that the limiting plate is always tightly attached to the block, effectively preventing the block from shifting position during cutting. This solves the problems of poor cutting accuracy and non-compliant size. The second motor on the bottom of the base drives the rotating shaft and turntable to rotate, which makes it convenient to adjust the placement angle of the block. Multi-directional cutting can be completed without re-clamping, further ensuring the cutting accuracy.

[0015] (2) The cutting device for forming autoclaved aerated concrete blocks uses a third motor to drive the rotating rod to rotate. The eccentric bolt on the rotating plate drives the U-shaped frame to move up and down reciprocally through the transmission rod. The third sliding groove of the fixed part cooperates with the third slider of the U-shaped frame to ensure the stability of the U-shaped frame. The U-shaped frame drives the fixed plate and the cutter to move synchronously through the second buffer spring. The fourth sliding groove of the U-shaped frame cooperates with the fourth slider of the fixed plate to ensure the smooth movement of the cutter, so that the cutter can complete the cutting action quickly and efficiently. Compared with the traditional cutting method, the cutting efficiency is greatly improved, which meets the needs of high-efficiency production. A plunger is fixed on the connecting rod behind the right side plate at the top of the base. The plunger is located inside the tank. When the side plate moves, it will drive the connecting rod and the plunger to move inside the tank, so that the nozzle on the outer wall in front of the tank can spray the medium to suppress and clean the dust generated during the cutting operation, reduce dust flying, protect the environment, and improve the cleanliness of the production site and the working conditions of the operators.

[0016] Furthermore, the first buffer spring and the protective spring provide good cushioning when clamping the blocks, preventing the blocks from being damaged by excessive rigidity. The second buffer spring between the U-shaped frame and the fixed plate absorbs the impact force when the cutter cuts the blocks, reducing the wear of the cutter, extending the service life of the cutter, and also reducing equipment wear.

[0024] 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.

[0025] This utility model provides the following technical solution: a cutting device for forming autoclaved aerated concrete blocks.

[0026] Example 1: A trimming device for forming autoclaved aerated concrete (AAC) blocks. Through the threaded engagement of a double-threaded rod 11 and a first slider, the side plates 12 on both sides move relative to each other. Simultaneously, through the coordinated action of a first buffer spring 13, a support plate 14, and a limiting plate 15, the limiting plate 15 limits and fixes the concrete block. Furthermore, under the action of a turntable 16 and a rotating shaft, the placement angle of the concrete block can be easily adjusted, preventing the concrete block from easily shifting position during trimming, which could lead to poor trimming accuracy, dimensional defects, and other chain reactions affecting product quality. Figure 1 - Figure 4As shown, a cutting device for forming autoclaved aerated concrete blocks includes a base 1. First grooves are provided on both sides of the top of the base 1. A double-threaded rod 11 is rotatably connected within the first groove. A first motor is fixedly connected to the right end of the double-threaded rod 11. A first slider is threaded onto the double-threaded rod 11. A side plate 12 is fixedly connected to the top of the first slider. First buffer springs 13 are uniformly fixedly connected to the inner wall of the side plate 12. A support plate 14 is fixedly connected to the side of the first buffer spring 13 away from the side plate 12. A second groove is provided on the side of the support plate 14 away from the first buffer spring 13. A sliding rod is fixedly connected within the second groove. Second sliders are movably connected to both ends of the outer wall of the sliding rod, and a protective spring is movably sleeved on the outer wall of the sliding rod. A limit plate 15 is fixedly connected to the outer end of the second slider. A second motor is fixedly connected to the middle of the bottom surface of the base 1. A rotating shaft is fixedly connected to the output end of the second motor, and the rotating shaft passes through the middle of the base 1. A turntable 16 is fixedly connected to the top of the rotating shaft.

[0027] The first motor is started, which drives the double threaded rod 11 to rotate in the first groove at the top of the base 1. Since the first slider is threadedly connected to the double threaded rod 11, the first slider will drive the top side plate 12 to move relative to each other, causing the side plates 12 on both sides to move closer to the middle. The first buffer spring 13 on the inner wall of the side plate 12 pushes the support plate 14 to move. The second slider in the second groove on the support plate 14 slides on the slide rod, causing the limiting plate 15 to gradually approach and clamp the block. The protective spring on the outer wall of the slide rod is compressed, and its elastic force makes the limiting plate 15 fit tightly against the block, thus fixing the block. When it is necessary to adjust the cutting angle of the block, the second motor in the middle of the bottom surface of the base 1 is started. The output end of the second motor drives the rotating shaft to rotate. The rotating shaft passes through the middle of the base 1 and drives the top turntable 16 to rotate. The block placed on the turntable 16 rotates with the turntable 16, thereby realizing the adjustment of the block angle. After adjusting to the appropriate angle, the second motor is turned off.

[0028] Example 2: Unlike Example 1, the height of the cutter 25 can be adjusted through components such as the rotating rod 21, transmission rod 22, U-shaped frame 23, and fixed plate 24. Dust is then cleaned by the connecting rod 3 and plunger 31, preventing slow, inefficient cutting processes that cannot meet the demands of high-efficiency production. Furthermore, the large amount of dust generated during cutting pollutes the environment and negatively impacts the cleanliness of the production site and the working conditions of operators. Figure 5 - Figure 6As shown, fixing parts 2 are fixedly connected to both sides of the top of the base 1. A third motor is fixedly connected to the outer wall of the fixing part 2 on the right side of the top of the base 1. A rotating rod 21 is fixedly connected to the output end of the third motor. A rotating disk is fixedly connected to the left side of the rotating rod 21. An eccentric bolt is fixedly connected to the side of the rotating disk away from the rotating rod 21. A transmission rod 22 is movably connected to the eccentric bolt. A U-shaped part is movably connected to the bottom of the transmission rod 22. A U-shaped frame 23 is fixedly connected to the bottom of the U-shaped part. A second buffer spring is fixedly connected to the bottom of the U-shaped frame 23. A fixing plate 24 is fixedly connected to the bottom of the second buffer spring. A cutter 25 is fixedly connected to the middle of the bottom surface of the fixing plate 24. A third sliding groove is provided on the inner wall of component 2. A third slider is fixedly connected to the outer walls of both sides of the U-shaped frame 23. The fixing component 2 and the U-shaped frame 23 are slidably connected through the third sliding groove. A fourth sliding groove is provided on the inner wall of the U-shaped frame 23. A fourth slider is fixedly connected to the outer walls of both sides of the fixing plate 24. The U-shaped frame 23 and the fixing plate 24 are slidably connected through the fourth sliding groove. A connecting rod 3 is fixedly connected to the rear of the right side plate 12 at the top of the base 1. A plunger component 31 is fixedly connected to the connecting rod 3. A tank is fixedly connected to the rear of the top side plate 12 at the top of the base 1. The plunger component 31 is located inside the tank. A nozzle is fixedly connected to the front outer wall of the tank.

[0029] The third motor is started, which drives the rotating rod 21 to rotate. The rotating disk on the left side of the rotating rod 21 and the eccentric bolt on the rotating disk rotate accordingly. The eccentric bolt drives the U-shaped part to move through the transmission rod 22 connected to it, which in turn causes the U-shaped frame 23 to slide up and down along the third slide groove on the inner wall of the fixing part 2. The second buffer spring at the bottom of the U-shaped frame 23 pushes the fixing plate 24 to move. The fixing plate 24 slides along the fourth slide groove on the inner wall of the U-shaped frame 23 through the fourth sliders on both sides, which drives the cutter 25 on the bottom surface of the fixing plate 24 to move up and down to cut the block. During the movement of the side plate 12 and the cutting operation, the connecting rod 3 behind the right side plate 12 at the top of the base 1 will move accordingly. The plunger 31 on the connecting rod 3 reciprocates in the tank, causing the medium in the tank to be sprayed out through the nozzle to treat the dust generated by the cutting and achieve the dust removal effect.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
