Description

Technical Field

[0001] The invention belongs to the technical field of special machinery manufacturing for building material production, in particular to a production and forming device for autoclaved lime bricks which is easy to demould. Background Art

[0002] Autoclaved sand-lime bricks, made from sand, lime, and industrial waste, are environmentally friendly, and their low energy consumption and high strength achieved through high-pressure steam curing have made them a leading new wall material. The core of their production, the autoclaved sand-lime brick forming unit, achieves high efficiency and energy conservation through process optimization and equipment innovation. This not only aligns with national energy conservation and environmental protection policies, but also promotes the building materials industry's transition towards a low-carbon, sustainable future.

[0003] When the existing autoclaved lime brick production and molding device is in use, first, the autoclaved ash raw materials that meet the standards, such as fly ash, coal slag, etc., are measured and mixed with lime, gypsum and aggregate in a scientific ratio. These raw materials are fully stirred by adding water in a mixer to ensure uniform mixing. Subsequently, the stirred materials enter the digestion bin for digestion, so that the quicklime is fully digested and undergoes a pre-hydration reaction with materials such as fly ash, thereby improving the plasticity of the mixture. Next, the materials are sent to the molding machine for press molding and are pressed into brick blanks. The formed brick blanks are stacked on a curing trolley and sent to a static curing kiln for grouping and static parking, so that the brick blanks reach a certain strength before autoclaving. Finally, the brick blanks are sent to the autoclave, where they undergo a hydrothermal reaction under high-temperature saturated steam curing to form stable hydration products, thereby obtaining the required strength and performance.

[0004] However, in the existing autoclaved lime brick production and molding equipment, since the autoclaved lime brick raw materials are made by stirring and mixing, they have a certain viscosity. Before each pressing and molding, the staff needs to apply a release agent to each mold groove. This process is extremely cumbersome. There are many mold grooves, and manual coating one by one not only consumes a lot of time, but also increases labor costs, seriously slowing down the production progress and resulting in low production efficiency. Moreover, after each pressing and forming, the upper surface of the pressed autoclaved gray brick is relatively dry, because the mold surrounds the brick, the contact area between the upper surface and the mold is relatively small, and it is directly exposed to the external environment. After pressing and forming, moisture moves from the inside of the brick to the upper surface, and the evaporation channel of moisture on the upper surface is more direct and the evaporation rate is faster, which causes the upper surface to dry. Therefore, dry powder will be produced on its surface. These dry powders not only affect the appearance quality of the bricks, making their surface rough and unsightly, but may also cause dust to fly during the subsequent transportation and stacking process, polluting the production environment and posing a threat to the health of workers. In addition, the presence of dry powder may also affect the bonding performance between bricks, reducing the overall quality of the finished autoclaved gray bricks.

[0005] To this end, the present invention provides a production and forming device for autoclaved lime bricks which is easy to demould. Summary of the Invention

After the auxiliary spring is squeezed, the connecting hole on the surface of the convex plate is aligned with the positioning hole inside the push plate. At this time, the release agent in the storage box is pressurized and passes into the connecting hole along the positioning hole, and then flows into the connecting groove opened on the push plate, and then flows into the auxiliary tube fixed on the side, and finally flows from the nozzle on the lower surface of the spray plate to the mold groove.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] Example 1: Figures 1 to 8 As shown, an autoclaved gray brick production and forming device that is easy to demould described in an embodiment of the present invention includes a body, a first hydraulic cylinder is fixedly connected to the top of the body, an output end of the first hydraulic cylinder is fixedly connected to a top plate, a lower surface of the top plate is fixedly connected to a plurality of extrusion blocks, a plurality of mold grooves are opened in the middle of the body, a discharge port is opened at the bottom end of the body, a spraying assembly is arranged inside the body, the spraying assembly includes a plurality of sealing plates rotatably arranged inside the body, two push plates are slidably connected inside the body, the two push plates are driven by a third hydraulic cylinder arranged on one side of the body, a rotating plate is rotatably arranged on both sides of one of the push plates, a spray plate is fixedly connected to one side of the rotating plate, a nozzle is opened on the lower surface of the spray plate, an auxiliary pipe is fixedly connected to one side of the rotating plate, the auxiliary pipe is communicated with a connecting groove opened inside the push plate, and the connecting groove is communicated with a storage box arranged on the outer wall of the body; A humidifying assembly is provided on the inner wall of the discharge port, and the humidifying assembly includes a first guide rail fixedly connected to both sides of the inner wall of the discharge port, a slider is slidably connected in the first guide rail, a rotating roller is rotatably connected to one side of the slider, a spray plate is fixed on the circumferential surface of the rotating roller, and a plurality of spray holes for spraying water mist are opened on one side of the spray plate.

[0024] Specifically, in the existing autoclaved lime brick production and molding equipment, since the autoclaved lime brick raw materials are made by stirring and mixing and have a certain viscosity, workers need to apply a release agent to each mold groove before each pressing and molding. This process is extremely cumbersome. There are many mold grooves, and manual coating of each groove not only consumes a lot of time, but also increases labor costs, seriously slowing down production progress and resulting in low production efficiency. Moreover, after each pressing and forming, the upper surface of the pressed autoclaved lime brick is relatively dry, because the mold surrounds the brick, the contact area between the upper surface and the mold is relatively small, and it is directly exposed to the external environment. After pressing and forming, moisture moves from the inside of the brick to the upper surface, and the evaporation channel of the moisture on the upper surface is more direct and the evaporation rate is faster, which causes the upper surface to dry out. As a result, dry powder will be produced on its surface. This dry powder not only affects the appearance quality of the brick, making the surface rough and unsightly, but may also cause dust to fly during the subsequent transportation and stacking process, polluting the production environment and posing a threat to the health of workers. In addition, the presence of dry powder may also affect the bonding performance between bricks, reducing the overall quality of the finished autoclaved lime brick. Therefore, the present invention sets the above structure to solve the above problem. First, when the device is working, the mixed material is poured into the mold groove, and then the first hydraulic cylinder is started to push the top plate downward, and the extrusion block extrudes the material in the mold groove to form. After the extrusion is completed, the brick blank is discharged to complete the one-time forming. At this time, the push plate is driven to move by starting the third hydraulic cylinder to release the fixation of the rotating plate. The rotating plates on both sides of the push plate drive the spray plate to rotate to the position just above the mold groove. Then, the release agent in the storage box enters the spray plate through the connecting groove and the auxiliary pipe, and is sprayed from the nozzle to spray the mold groove. After that, the push plate continues to move in the opposite direction to drive the rotating plate to return to the inside of the machine body, and then the material is refilled to press and form the brick blank. In addition, a humidifying component is provided at the discharge port. When the brick blank is formed and moves down to the discharge port, the first guide rail is started, and the slider can slide in the first guide rail. The rotating roller drives the spray plate to rotate to a suitable angle. The spray plate sprays water mist through the spray hole to humidify the brick blank to prevent the product from cracking due to excessive drying. By setting up the spraying component, the mold groove can be sprayed in time after the product is formed and unloaded, which improves production efficiency. The humidification component can effectively avoid defects such as cracks in the product due to rapid drying during the discharge process, ensuring the integrity and aesthetics of the product. The entire device integrates extrusion molding, spraying and humidification processes, reducing the transfer time of the product between different processes, improving the continuity and automation of production, reducing labor costs and labor intensity, and helping to improve overall production efficiency and meet the needs of large-scale production.

[0025] like Figure 6As shown, the spraying assembly of this embodiment includes two positioning plates fixedly connected to one side of the push plate, a torsion spring is arranged between the two positioning plates, the rotating plate is fixed to the torsion spring, and assists in resetting the rotating plate. Both sides of the push plate are slidably connected with a push rod, one end of the push rod is fixedly connected to a telescopic rod, the circumferential surface of the telescopic rod is sleeved with a compression spring, one end of the push rod is fixedly connected to a moving rod, the end of the moving rod is fixedly connected to a hook block, and the end of the rotating plate is fixedly connected to a hook plate.

[0026] Specifically, when spraying is carried out, the push plate is pushed, and the push rod squeezes the inner wall of the machine body, thereby squeezing the compression spring, compressing the compression spring, and the push rod pushes the moving rod to slide. The sliding of the moving rod causes the hook block to move, so that the hook block releases the limit on the hook plate. At this time, the rotating plate pushes the sealing plate under the action of the torsion force of the torsion spring, and the rotating plate is horizontally mounted above the mold groove, and the spray plate adds the release agent into the mold groove; during the spraying work, a series of linkage actions are triggered by pushing the push plate, so that the rotating plate is automatically horizontally mounted above the mold groove, which can quickly create a relatively independent space for subsequent spraying, avoiding waste and pollution caused by overflow of the release agent. At the same time, the spray plate accurately adds the release agent to the mold groove, which helps the product to be smoothly demolded in the future, reduces product damage caused by demolding difficulties, ensures product quality, and improves production efficiency and yield.

[0027] like Figure 6 As shown, one end of the push plate of this embodiment is slidably connected to a convex plate, the tip of the convex plate is in the same position as the tip of the push rod, one end of the convex plate is fixedly connected to two auxiliary springs, the two auxiliary springs are fixedly connected to the inner wall of the push plate, a connecting hole is opened on the surface of the convex plate, and a positioning hole is opened inside the push plate.

[0028] Specifically, when the push plate is pushed, the convex plate contacts the inner wall of the machine body, and the convex plate contracts toward the inside of the push plate to squeeze the auxiliary spring. After the auxiliary spring is squeezed, the connection hole on the surface of the convex plate is aligned with the positioning hole inside the push plate. At this time, the mold release agent in the storage box is pressurized and flows into the connection hole along the positioning hole, then flows into the connection groove provided on the push plate, and then flows into the auxiliary pipe fixed on the side, and finally flows from the nozzle on the lower surface of the spray plate into the mold groove; During the pushing process of the push plate, the convex plate contacts the inner wall of the machine body to trigger a series of actions, so that the release agent can flow into the mold groove accurately and orderly. With the help of auxiliary springs, the connecting holes and the positioning holes are automatically aligned, ensuring the smooth flow of the release agent delivery channel and avoiding interruption of the release agent supply due to blocked channels. The whole process is highly automated and can efficiently and accurately add the release agent to the mold groove, creating good conditions for product demoulding and improving production efficiency and quality.

[0029] Example 2: Figures 1 to 8As shown, comparative example 1, another embodiment of the present invention is: the humidifying component includes a second guide rail fixedly connected to the upper surface of the first guide rail, a connecting block is slidably connected in the second guide rail, the top of the connecting block is fixedly connected to an auxiliary plate, the lower surface of the auxiliary plate is fixedly connected to a connecting pipe, the bottom end of the connecting pipe is fixedly connected to an auxiliary ring, and an auxiliary hole is opened on the circumferential surface of the rotating roller.

[0030] Specifically, when the humidification work is carried out, the rotating roller is driven to rotate, and the auxiliary hole on the circumferential surface of the rotating roller rotates a certain angle to align with the connecting pipe on the circumferential surface of the auxiliary ring. At this time, the fixed box fixed to one side of the body pressurizes water through the hose to the inside of the auxiliary plate through the built-in pressure, and then flows into the interior of the rotating roller along the connecting pipe and is sprayed out from the spray hole of the spray plate to humidify the autoclaved lime bricks; By driving the rotating roller to rotate, the auxiliary hole and the connecting pipe are precisely aligned to ensure smooth water flow and achieve precise control of the humidification process. By using a fixed box to pressurize water supply, water can be sprayed out from the spray plate nozzle at an appropriate pressure, so that the humidification mist evenly covers the autoclaved gray bricks, ensuring the consistency of the humidification effect. This not only effectively prevents the gray bricks from having quality problems due to uneven drying, but also improves the humidification efficiency, ensuring production stability and product quality.

[0031] like Figure 7 As shown, the lower surface of the auxiliary plate of this embodiment is fixed with a fixing frame, the interior of the fixing frame is fixed with a motor, the output end of the motor is fixed with an auxiliary wheel, the auxiliary wheel is engaged with a gear fixed with one end of the rotating roller, and both ends of the rotating roller are also rotatably connected to coating rollers.

[0032] Specifically, after the spraying assembly has finished filling the mold groove bottom wall with the release agent, the second hydraulic cylinder provided on the bottom wall of the machine body is started, and the second hydraulic cylinder drives the mold bottom plate to move downward. At this time, the motor is started to drive the auxiliary wheel to drive the gear to rotate a certain angle, so that the coating roller contacts the mold plate, and then the first guide rail and the second guide rail are started to drive the rotating roller to drive the coating roller to apply the release agent to the mold plate. First, the mold base is driven downward by the second hydraulic cylinder to create space and conditions for subsequent coating, which is flexible and efficient in operation. Then, the motor drives the gear to rotate so that the coating roller contacts the mold plate accurately. The first and second guide rails drive the rotating roller to drive the coating roller to apply the release agent, ensuring the uniformity and comprehensiveness of the coating, effectively reducing the dead corners of the release agent residue, improving the demoulding effect, reducing the difficulty of product demoulding, and ensuring product quality and production efficiency.

[0033] Working principle: first, when the device is working, the mixed material is poured into the mold groove, and then the first hydraulic cylinder is started to push the top plate downward, and the extrusion block extrudes the material in the mold groove to form. After the extrusion is completed, the brick blank is discharged to complete the primary forming. At this time, the push plate is driven to move by starting the third hydraulic cylinder. After the push plate is pushed to move, the push rod squeezes the inner wall of the machine body, thereby squeezing the compression spring, compressing the compression spring, and the push rod pushes the moving rod to slide. The sliding of the moving rod causes the hook block to move, so that the hook block releases the limit of the hook plate. At this time, the rotating plate pushes the sealing plate under the action of the torsion force of the torsion spring. After the fixation of the rotating plate is released, the rotating plates on both sides of the push plate drive the spray plate to rotate to the position just above the mold groove; When the push plate is pushed, the convex plate contacts the inner wall of the machine body, and the convex plate contracts and squeezes the auxiliary spring toward the inside of the push plate. After the auxiliary spring is squeezed, the connection hole on the surface of the convex plate is aligned with the positioning hole inside the push plate. At this time, the mold release agent in the storage box is pressurized and flows into the connection hole along the positioning hole, then flows into the connection groove opened on the push plate, and then flows into the auxiliary pipe fixed on the side, and finally flows from the nozzle on the lower surface of the spray plate into the mold groove; During the pushing process, the convex plate contacts the inner wall of the machine body to initiate a series of actions, allowing the release agent to flow into the mold groove accurately and orderly. The auxiliary spring automatically aligns the connecting hole and the positioning hole, ensuring the smooth flow of the release agent delivery channel and avoiding interruptions in the release agent supply due to channel obstruction. The entire process is highly automated, and can efficiently and accurately add the release agent to the mold groove, creating good conditions for product demoulding and improving production efficiency and quality. When the spraying assembly has finished filling the mold groove bottom wall with the release agent, the second hydraulic cylinder provided on the bottom wall of the machine body is started, and the second hydraulic cylinder drives the mold bottom plate to move downward. At this time, the motor is started to drive the auxiliary wheel to drive the gear to rotate a certain angle, so that the coating roller contacts the mold plate. Then, the first guide rail and the second guide rail are started to drive the rotating roller to drive the coating roller to apply the release agent to the mold plate. After that, the push plate continues to move in the opposite direction to drive the rotating plate to return to the inside of the machine body, and then the material is added again to press and form the bricks. In addition, a humidifying component is set at the discharge port. When the humidifying work is carried out, the rotating roller is driven to rotate, and the auxiliary hole on the circumference of the rotating roller rotates a certain angle to align with the connecting pipe on the circumference of the auxiliary ring. At this time, the fixed box fixed to one side of the machine body pressurizes water through the hose to the inside of the auxiliary plate through the built-in pressure, and then passes into the inside of the rotating roller along the connecting pipe and is sprayed out from the spray hole of the spray plate to humidify the autoclaved lime bricks. By driving the rotating roller to rotate, the auxiliary hole and the connecting pipe are precisely aligned to ensure smooth water flow and achieve precise control of the humidification process. By using a fixed box to pressurize water supply, water can be sprayed out from the spray plate nozzle at an appropriate pressure, so that the humidification mist evenly covers the autoclaved gray bricks, ensuring the consistency of the humidification effect. This not only effectively prevents the gray bricks from having quality problems due to uneven drying, but also improves the humidification efficiency, ensuring production stability and product quality.
