Description

Technical Field

[0001] This utility model belongs to the technical field of production equipment for non-removable composite formwork for construction, and particularly relates to a wet molding production line for non-removable formwork for construction. Background Technology

[0002] Non-removable composite formwork, as the name suggests, does not need to be removed after concrete pouring, but remains permanently in the building as part of the structure. The formwork itself is a composite board composed of cement, aggregate, fiber, steel mesh, etc., and its compressive strength, flexural strength, and impact resistance are significantly superior to conventional cement-pressed boards; for details, see the applicant's earlier application for a prefabricated non-removable composite formwork, publication number CN213062545U.

[0003] The following problems exist in actual production: Uneven mixing: Existing production processes for non-removable composite formwork require precise proportioning and uniform mixing of various raw materials. Current production lines typically use mechanical or manual mixing to combine cementitious materials, aggregates, additives, and other raw materials to form a finished slurry with specific properties. However, due to factors such as the nature of the raw materials, the precision of the mixing equipment, and the skill level of the operators, the uniformity of material mixing is often difficult to achieve. Uneven mixing can lead to significant performance fluctuations in the non-removable composite formwork, affecting its performance during use.

[0004] Dust pollution is a significant environmental concern during the wet molding process of non-removable composite formwork for construction. Dust pollution, in particular, significantly impacts the normal operation of the production line and the surrounding environment. During the mixing process, friction and collision between materials inevitably generate dust. This dust generation increases dramatically, especially when materials are dry or unevenly mixed. Dust not only pollutes the production environment, affecting aesthetics and cleanliness, but more importantly, it poses a serious threat to the health of operators. Long-term inhalation of dust can lead to respiratory illnesses and even occupational diseases. Furthermore, dust can adhere to production equipment, affecting its normal operation and lifespan, and increasing maintenance costs.

[0005] To address dust pollution, various dust removal devices and methods have emerged in existing technologies. For example, twin-shaft dust humidifying mixers control the amount of water added to humidify and mix dry powdery materials to a suitable humidity level, thereby reducing dust emissions. Baghouse dust collectors utilize filter bags to capture dust particles from dust-laden gas, achieving dust removal. However, these devices and methods are mostly designed for specific stages or single pieces of equipment, making it difficult to achieve comprehensive dust removal throughout the batching and mixing process.

[0006] Furthermore, in the field of batching and mixing, there are still problems such as low batching accuracy and poor equipment adaptability. Traditional batching and mixing integrated machines can often only process single or a few types of aggregates, making it difficult to meet complex batching needs. At the same time, the equipment has limitations in adapting to different types, particle sizes, and moisture content of aggregates, affecting production efficiency and product quality.

[0007] Water pollution during molding: In the preparation of non-removable composite formwork, the mortar material undergoes a hydration reaction, leaving some residual moisture. This moisture often occupies space in traditional processes, weakening the formwork's strength. To ensure the quality of the formwork's molding, high-pressure presses are necessary for drainage. However, unfortunately, existing molding equipment lacks an effective filtration mechanism, failing to prevent mortar material from being discharged along with the pressure-filtered water. We have conducted a comprehensive and in-depth analysis of this significant technical deficiency.

[0008] The fabrication of non-removable composite templates requires a compression molding process. Existing production lines typically use equipment such as hydraulic presses and pressure machines for compression molding.

[0009] Current compression molding equipment lacks filtration capabilities, making it impossible to prevent mortar materials from being discharged along with the filter water. This is primarily due to the absence of an effective filtration mechanism in these machines. This deficiency leads to several problems, primarily in resource waste and increased costs. During the molding process, a large amount of mortar material, rich in valuable resources such as cementitious materials and aggregates, is discharged along with the filter water. This loss not only represents a direct waste of building materials but also forces companies to increase raw material procurement, thereby raising production costs. Simultaneously, the filter water containing impurities cannot be directly recycled, further wasting water resources.

[0010] Environmental pollution is another major problem. The direct discharge of untreated filter water containing mortar materials poses a serious threat to surrounding water bodies. Harmful substances such as chemical solvents and heavy metals in the water can have long-term effects on water quality and damage aquatic ecosystems. If the filter water seeps into the soil, it will also pollute the soil, affecting crop growth and soil ecological balance, and ultimately threatening human food safety.

[0011] In terms of product quality, the loss of mortar material leads to uneven composition of the molded composite formwork, potentially impairing its mechanical properties and service life. Furthermore, the lost material may create voids, cracks, and other surface defects during molding, severely reducing the market competitiveness of the composite formwork. Production efficiency is also affected. Prolonged operation of molding equipment in an environment containing large amounts of mortar material easily causes wear and blockages, increasing equipment maintenance costs. Extended downtime due to equipment blockages or malfunctions further reduces production efficiency, impacting the company's economic benefits.

[0012] More seriously, this deficiency also makes existing compression molding equipment perform poorly in terms of environmental protection and sustainability. With increasing environmental awareness and stricter environmental regulations, equipment lacking filtration capabilities can no longer meet environmental requirements, limiting its application and promotion in the market. In the context of a circular economy and resource conservation, the inability to effectively recycle and reuse lost mortar materials and water resources makes this technology particularly outdated and unsustainable.

[0013] In conclusion, the environmental dust pollution and molding water pollution problems existing in the wet molding production line of non-removable formwork for construction cannot be ignored. To solve these problems, effective control measures need to be taken, such as strengthening dust collection and treatment, ensuring the cleanliness of water sources, and standardizing the use and management of molding water.

The upper part of the storage silo 1-2 is provided with a fine aggregate inlet 1-3. A sloping guide silo 1-4 is connected to the storage silo 1-2. The lower end of the sloping guide silo 1-4 is provided with a feed pipe 1-5. Inside the sloping guide silo 1-4... The feeding pipe 1-5 has N inlets 1-5-1 along its length. A spiral feeding shaft 1-5-2 is installed inside the feeding pipe 1-5 to push the gelled dry powder material. The spiral feeding shaft 1-5-2 is connected to a spiral feeding motor 1-5-3 that drives the spiral feeding shaft to rotate. The spiral feeding motor 1-5-3 can be directly connected to the spiral feeding shaft 1-5-2, or it can be connected to the spiral feeding shaft 1-5-2 by a transmission component, such as a belt, synchronous belt, or chain.

[0081] Technical Principle: The technical principle of this fine aggregate dry powder storage silo for construction products is mainly based on the combination of sealed storage and mechanical conveying. The silo body 1-1 constitutes the main structure of the storage silo 1-2, used to store fine aggregate dry powder. A fine aggregate inlet 1-3 located at the top of the storage silo 1-2 allows for convenient loading of fine aggregate into the storage silo 1-2. A ramp guide silo 1-4 is connected to the storage silo 1-2, and its design allows the fine aggregate to flow smoothly into the feed pipe 1-5. N feed inlets 1-5-1 arranged along the length of the feed pipe 1-5 ensure that the fine aggregate can enter the feed pipe 1-5 evenly from the storage silo 1-2. A screw feeder shaft 1-5-2 installed inside the feed pipe 1-5 rotates under the drive of a screw feeder motor 1-5-3, pushing the gelled dry powder material along the feed pipe 1-5, achieving continuous and uniform output of fine aggregate. The screw feeder motor 1-5-3 can be connected to the screw feeder shaft 1-5-2 via direct connection or transmission components (such as belts, timing belts, and chains), providing a flexible choice of drive method.

[0082] Furthermore, an inlet opening adjustment device 1-6 is installed within the inclined flow guide chamber 1-4 to adjust the inlet opening. This allows the inlet opening to be flexibly adjusted according to actual needs. This design not only improves the controllability of fine aggregate feeding but also effectively prevents uneven feeding or blockage caused by excessively large or small openings. By adjusting the inlet opening, the flow state of fine aggregate can be optimized, ensuring the stable operation of the storage silo, improving construction efficiency, and reducing maintenance costs.

[0083] More preferably, the inlet opening adjustment device 1-6 includes an adjustment rod 1-6-1 parallel to the axis of the feed pipe 1-5. A support rod 1-6-2 is vertically provided on the adjustment rod 1-6-1 corresponding to the inlet position. A flow control plate 1-6-3 is fixedly provided at the lower end of the support rod 1-6-2. The inner wall of the flow control plate 1-6-3 is an arc-shaped structure with the same diameter as the outer diameter of the feed pipe 1-5. One end of the adjustment rod 1-6-1 extends into the end plate of the inclined guide chamber 1-4. A driving component is provided on the outside of the end plate of the adjustment rod 1-6-1 to drive the adjustment rod to move in the axial direction. The driving component can preferably have the following structure: the end of the adjusting rod is provided with a threaded section, and a lead screw nut disc is fitted on the threaded section. The outer circumference of the lead screw nut disc is a worm gear, which is connected to a worm. The worm is connected to an opening adjustment motor or a handwheel. Rotating the handwheel or the opening adjustment motor drives the lead screw nut disc to rotate. The lead screw nut disc has no axial displacement, and thus, under the threaded engagement, the lead screw nut disc drives the adjusting rod to move linearly along the axis of the feed pipe. Alternatively, a hydraulic cylinder or a pneumatic cylinder can be used to drive the adjusting rod 1-6-1 to move linearly along the axis of the feed pipe 1-5. In this technical solution, the inlet opening adjustment device 1-6 achieves the adjustment of the inlet opening through a combination structure of the adjusting rod 1-6-1, the support rod 1-6-2, and the flow control plate 1-6-3. The adjusting rod 1-6-1 is set parallel to the axis of the feed pipe 1-5. The support rod 1-6-2 is vertically fixed on the adjusting rod 1-6-1 at the position corresponding to the feed inlet. The flow control plate 1-6-3 is fixed to the lower end of the support rod 1-6-2. Its inner wall has an arc-shaped structure with the same diameter as the outer diameter of the feed pipe 1-5, which can fit tightly against the feed pipe 1-5, thereby controlling the opening of the feed inlet. One end of the adjusting rod 1-6-1 extends out of the end plate of the inclined guide chamber 1-4, and is driven to move axially by a drive component (such as a screw nut disc and an opening adjustment motor or handwheel, hydraulic cylinder, pneumatic cylinder, etc.), thereby adjusting the position of the flow control plate 1-6-3 and achieving precise control of the feed inlet opening. At the same time, when the feed inlet is obstructed, the reciprocating linear motion of the adjusting rod driven by the drive component can cut the material and loosen it, ensuring smooth feed from each feed inlet.

[0084] Preferably, the side wall of the storage silo 1-2 is provided with a maintenance manhole 1-2-1. This facilitates the inspection and maintenance of the interior of the storage silo 1-2, improving the maintainability and ease of use of the equipment.

[0085] Preferably, the top of the storage silo 1-2 is equipped with a dust removal fan 1-7. This effectively reduces dust escape, improves the working environment, protects worker health, reduces environmental pollution, and maintains pressure balance inside and outside the silo.

[0086] Furthermore, the storage silo 1-2 is provided with reinforcing ribs 1-8. This improves the structural strength and stability of the silo body 1-1, effectively resists external forces, reduces the risk of deformation and damage, and extends the service life of the equipment.

[0087] For further recommendations, please refer to [link / reference]. Figures 8 to 17 The dust removal, batching, and mixing integrated machine 2 includes a mixing frame 2-1, which is primarily constructed of steel as the supporting structure for the entire equipment. The mixing frame not only provides stable support but also allows for efficient collaboration among various components through a rational layout. Its design considers the overall stability and ease of maintenance, ensuring the stability and durability of the equipment during long-term operation. At least two aggregate bins 2-2 are installed on the mixing frame for storing fine and / or coarse aggregates. This design allows the equipment to simultaneously store multiple types of aggregates (such as fine and coarse aggregates, or aggregates of different colors), improving the flexibility and efficiency of batching. Users can quickly switch or mix different aggregates according to production needs without frequent replacement of aggregate bins, thus saving time and labor costs. A sloping cofferdam 2-2-1 can also be added to the upper edge of the aggregate bins 2-2 to expand the volume of the aggregate bins and provide protection. Please refer to [link to relevant documentation]. Figure 15The aggregate bin is also equipped with reinforcing ribs 2-2-2 to improve its strength. The mixing and batching bin 2-3 is used for mixing and batching. An aggregate inlet bin 2-4 is installed above the mixing and batching bin. The aggregate inlet bin optimizes the material flow path, reducing blockage and dust generation during the inlet process. A reasonable bin structure and discharge port design ensure smooth material entry into the mixing and batching bin. The aggregate inlet bin is connected to the dust collection chamber 2-5 via a flexible cover 2-5-1. This flexible cover effectively isolates dust, preventing it from escaping into the environment. The flexible cover design also considers vibration and deformation during operation, ensuring reliable and airtight connections. Dust collector bags 2-6 are installed inside the dust collection chamber, and a fan 2-7 is installed on top of the dust collection chamber, forming a highly efficient dust collection system. The dust collection chamber design considers dust collection and emission efficiency, ensuring timely removal of dust generated during equipment operation. As a core component of the dust collection system, the filter bag boasts highly efficient dust collection capabilities. Its materials and structural design are carefully selected and optimized to maintain high-efficiency dust collection over the long term, while also being easy to maintain and replace. The filter bag provides the necessary power support for the dust collection system. By adjusting the fan speed and airflow, the negative pressure and dust emission rate within the dust collection chamber can be controlled, ensuring effective dust collection while reducing energy consumption. The fan can be installed on the side or top of the dust collection chamber, significantly improving space utilization and maintenance convenience. Side installation effectively utilizes vertical space, resulting in a compact equipment layout and improved overall workshop space utilization. Top installation frees up horizontal space, facilitating material flow and the installation of other equipment. During maintenance, side installation allows for easy access to the fan for quick inspection and repair, reducing maintenance costs. While top-mounted installation requires consideration of maintenance platform setup, the overall layout is more flexible, allowing for adjustments to maintenance strategies based on actual needs. In summary, the selection of fan installation locations must comprehensively consider both space and maintenance requirements to achieve optimal technical results. Fans from different integrated mixers in the same workshop can be connected in parallel. The advantages of parallel fan operation include: airflow regulation and distribution: After connecting fans from different integrated mixers in parallel within the same workshop, airflow can be flexibly adjusted and distributed by regulating the speed or number of fans in operation. This optimizes the airflow supply according to the actual needs of different integrated mixers, ensuring each device receives sufficient dust removal capacity. System efficiency improvement: Parallel fan operation significantly increases the total airflow of the system, thereby improving the dust removal efficiency of the entire workshop. Simultaneously, because the fans can complement and share the load, the stability and reliability of the system are also improved. Operation and control: The operation and control of parallel fans require more precise and intelligent control.By integrating and controlling the parallel fans, unified management and scheduling can be achieved, enabling automatic airflow adjustment and fault warning functions, reducing the need for manual intervention and improving operation and maintenance efficiency. Each aggregate bin 2-2 has an aggregate conveyor belt 2-8 at its bottom, responsible for transporting aggregates from the aggregate bin to the aggregate inlet bin. Its design considers the characteristics of the material and conveying efficiency, ensuring uniform and continuous material transport. The discharge end of the aggregate conveyor belt is adjacent to the aggregate inlet 2-4-1 of the aggregate inlet bin 2-4. A self-weight tilting door 2-4-2 is hinged to the upper edge of the aggregate inlet inside the aggregate inlet bin, automatically opening and closing due to its own weight. When the material on the aggregate conveyor belt reaches a certain weight, the self-weight tilting door automatically opens to allow material to enter the aggregate inlet bin; after the material transport is completed, the door automatically closes to prevent dust escape. This design not only simplifies the operation process but also improves the automation level of the equipment. The dust removal chamber is equipped with spray nozzles 2-9, which are connected to the water inlet pipe. These nozzles spray water within the dust removal chamber to serve as a mixing medium and to moisten the dust and promote its settling. A mixing shaft 2-10 is installed inside the mixing and batching silo, with mixing blades 2-11 mounted on it. A mixing and stirring drive motor 2-12, connected to the mixing shaft, is installed at the bottom of the mixing and batching silo. Weighing sensors 2-13 are located around the mixing and batching silo, with their upper ends connected to the mixing frame. These sensors are used to monitor the weight of the materials in real time. Feedback signals to the control system allow for precise control of the amount of materials added to ensure accurate proportioning. In this embodiment, the weight of each aggregate is recorded primarily by increasing its weight. A discharge port 2-3-1 is provided on the mixing and batching silo 2-3 corresponding to the finished slurry conveyor. A discharge gate assembly 2-14 is installed on the discharge port to control the outflow of the finished slurry. The discharge gate assembly is connected to a drive cylinder 2-15 that drives the discharge gate to move or rotate; the drive cylinder enables the gate to move or rotate, thereby precisely controlling the discharge volume. This design not only improves the accuracy of discharge but also reduces energy consumption and noise. The aggregate inlet bin, flexible cover, or mixing bin is connected to the dry powder storage bin via a screw conveyor. The screw conveyor is used to transport dry powder materials from the storage bin to the mixing bin or aggregate inlet bin. Its design takes into account the characteristics of the material and conveying efficiency, and adopts a screw propulsion method to achieve continuous and stable conveying.

[0088] Further preferably, a pulse-jet cleaning device 2-16 is installed on the dust collection chamber. In summary, although the pulse-jet cleaning device itself is known technology, when combined with this invention, it exhibits unique technical effects by optimizing the cleaning process, improving cleaning efficiency, extending filter bag lifespan, enhancing dust collection effect, reducing operating costs, and increasing adaptability. These effects collectively improve the overall performance and economy of the dust collection system, providing a more efficient and reliable solution for the industrial dust collection field.

[0089] Further preferably, the aggregate inlet bin 2-4-1 is provided with a viewing window 2-4-3, and a transparent glass 2-4-4 is installed on the viewing window. This design improvement greatly facilitates monitoring and observation during actual operation. During the mixing process, operators can directly observe the mixing situation inside the aggregate inlet bin through the transparent glass, without opening the bin door or interrupting the mixing process, thus ensuring the continuity and stability of the mixing process. At the same time, the high clarity of the transparent glass can accurately reflect the mixing state of the materials inside the bin, providing operators with intuitive visual feedback. This design not only improves the controllability of the mixing process, but also helps to promptly detect and handle possible uneven mixing or abnormal situations, ensuring mixing quality and production efficiency. In summary, the viewing window design in this utility model is a practical and efficient improvement.

[0090] For further recommendations, please refer to [link / reference]. Figure 14 The discharge gate assembly 2-14 includes a gate 2-14-1, which has a fan-shaped structure. This design allows the gate to perfectly fit the outlet of the mixing silo during rotation, effectively preventing material leakage and ensuring the accuracy and sealing of the discharge. A rotating shaft 2-14-2 is mounted at the center of rotation of the gate, and is securely installed on the side wall of the mixing silo via a bearing seat, ensuring the stability and durability of the gate's rotation. The rotating shaft is hinged to a bearing seat 2-14-3, which is also mounted on the side wall of the mixing silo. A drive arm 2-14-4 is mounted on the rotating shaft and is tightly connected to the rotating shaft. It is hinged to a drive cylinder, enabling flexible rotation of the discharge gate. The drive arm is hinged to a drive cylinder 2-15, which drives the discharge gate's rotation. The drive cylinder is mounted on the side wall of the mixing silo in a convenient and easy-to-operate and maintain position. The entire unloading gate assembly has a compact structure, with close cooperation between its various parts and strong overall integrity, effectively improving the unloading efficiency and reliability of the mixing and batching silo. This design not only meets production needs but also reflects a high degree of attention to the rationality and integrity of the equipment structure.

[0091] For further recommendations, please refer to [link / reference]. Figure 16 The inner wall of the aggregate bin is equipped with air cannons 2-2-3. These air cannons utilize compressed air to generate instantaneous impact force, effectively breaking up any material bridging or blockages that may form within the aggregate bin, ensuring smooth aggregate flow. This design improves the continuity and stability of aggregate conveying, reduces downtime caused by blockages, and thus enhances overall production efficiency. Simultaneously, the use of air cannons simplifies the aggregate bin cleaning process and reduces maintenance difficulty.

[0092] A further preferred embodiment is that when two aggregate bins are installed, they are symmetrically arranged on both sides of the mixing and batching bin. This technical solution brings significant technical benefits. First, the symmetrical layout makes the overall structure of the equipment more balanced and stable, improving the smoothness of equipment operation. Second, with the two aggregate bins located on opposite sides of the mixing and batching bin, it is convenient to simultaneously or independently convey aggregates to the mixing and batching bin, improving the flexibility and efficiency of batching. In addition, the symmetrical arrangement optimizes the material flow path, reducing resistance and energy consumption during material conveying. At the same time, this layout also facilitates maintenance and repair by operators, improving the maintainability and ease of use of the equipment.

[0093] For further recommendations, please refer to [link / reference]. Figure 17 A screen 2-17 is installed above the aggregate bin. This improvement greatly enhances the screening efficiency of fine aggregates. The inclined screen not only increases the screening area but also makes it easier for large aggregate particles to roll off under gravity. This design cleverly utilizes physical principles, making the screening process more efficient and smooth.

[0094] In a further preferred embodiment, the screen is inclined, and a receiving trough 2-18 is provided at the lower edge of the screen, with the receiving trough inclined downwards away from the aggregate inlet bin. This design ensures that large aggregate particles screened out can automatically roll into the receiving trough, achieving centralized collection. This not only avoids interference from large aggregate particles in subsequent production processes but also improves the continuity and stability of production. In summary, this preferred design, through the ingenious combination of the screen and the receiving trough, effectively separates large particles from fine aggregates, ensuring the smooth operation of subsequent production. At the same time, the automatic rolling and centralized collection design also reduces the labor intensity of workers, improves production efficiency, and brings new technological innovation to the aggregate processing industry.

[0095] Example 2, please refer to Figures 18 to 20 When four aggregate bins are set up, two aggregate bins are located on each side of the mixing bin, with the aggregate conveyor belts below the two bins on the same side arranged horizontally in a staggered pattern. Firstly, this design allows for the simultaneous storage and addition of four different materials, greatly improving the flexibility and versatility of batching. This meets the needs of complex production processes requiring multiple material ratios, enabling the mixing bin to adapt to the production of a wider variety of products. Secondly, the horizontally staggered aggregate conveyor belt arrangement avoids mutual interference during transport, ensuring that each material is accurately and stably delivered to the mixing bin. This improves production accuracy and stability, and reduces the production failure rate caused by material conveying problems.

[0096] Example 3, please refer to Figures 21 to 23When four aggregate bins are set up, two aggregate bins are set on each side of the mixing and batching bin, and the aggregate conveyor belts under the two aggregate bins on the same side are stacked one on top of the other. This layout can make full use of vertical space, making the structure of the entire equipment more compact, occupying less area, and improving the utilization rate of the site.

[0097] Please see 24 to Figure 27 The molding quantitative feeder 5 includes a frame 5-1, a receiving cylinder 5-2 mounted above the frame, and a mixing unit 5-3 installed inside the receiving cylinder. The frame serves as the supporting structure for the entire machine, ensuring the stability and reliability of the equipment. The receiving cylinder, mounted above the frame and equipped with the mixing unit, achieves uniform mixing of the material, providing an accurate basis for subsequent metering. This design improves the overall working efficiency of the equipment and the uniformity of material processing. The mixer unit 5-3 mainly includes a motor bracket 5-3-1 installed above the receiving cylinder, on which a mixing motor 5-3-2 is installed. The mixing motor is equipped with mixing blades 5-3-3. A discharge port 5-2-1 is installed at the lower end of the receiving cylinder. A pull-out metering component 5-4 is installed below the receiving cylinder to measure the amount of material discharged from the discharge port. The pull-out metering component includes a guide cylinder 5-4-1 located on the bottom plate of the receiving cylinder corresponding to the discharge port position. A suspension plate 5-4-2 is fixedly installed on the lower end face of the guide cylinder. A metering sealing support plate 5-4-3 is connected to the lower part of the suspension plate through a suspension rod. A feeding plate 5-4-4 is provided on the lower surface of the suspension plate. The front end of the feeding plate is a metering area 5-4-40, and the rear end is a sealing area 5-4-41. A metering cylinder 5-4-5 is provided in the metering area. The metering cylinder and the metering sealing support plate form a closed metering space, ensuring accurate control of the material quantity during the metering process. The metering cylinder corresponds to the discharge port, ensuring smooth material entry into the metering space and improving metering efficiency and accuracy. The sealing area is connected to a feeding cylinder 5-5, which is fixedly connected to a receiving cylinder 5-2. When receiving material, the metering cylinder aligns with the discharge port. During feeding, the feeding cylinder extends, pushing the metering sealing plate forward, gradually transitioning from the metering area to the sealing area, thus ensuring that material does not leak from the receiving cylinder while feeding. This equipment not only accurately measures the material quantity but also ensures the stability and safety of the material during the metering process. Furthermore, the equipment is easy to operate and maintain, greatly improving the production efficiency and product quality of precast building components.

[0098] More preferably, a movable measuring cylinder 5-4-6 is fitted onto the measuring cylinder, and the side wall of the movable measuring cylinder is fixedly connected to the measuring cylinder by fastening bolts 5-4-7. This design allows the movable measuring cylinder to be easily adjusted relative to the measuring cylinder, thereby achieving flexible adjustment for different product quantitative requirements. Quantitative adjustment for different materials or different production needs can be achieved without disassembling or replacing the measuring cylinder. This not only greatly improves the adaptability and flexibility of the equipment but also significantly reduces downtime and costs caused by replacing the measuring cylinder.

[0099] In a further preferred embodiment, a compression spring 5-4-8 is installed on the suspension rod below the metering sealing tray 5-4-3. The compression spring ensures that the metering sealing tray is always in contact with the metering cylinder or movable measuring cylinder. On the one hand, it ensures the sealing of the metering space, preventing material leakage during the metering process and thus guaranteeing the accuracy of the metering. On the other hand, the cushioning effect of the compression spring also reduces friction and wear between the metering sealing tray and the metering cylinder or movable measuring cylinder, extending the service life of the equipment. In addition, this design simplifies the equipment maintenance process, reduces maintenance costs, and improves the overall performance and reliability of the equipment.

[0100] More preferably, the suspension plate is provided with feeding plate support roller sets 5-6 on both sides. The support roller sets provide stable support for the metering sealing pallet, enabling it to remain stable during movement and reducing metering errors caused by shaking or tilting. Secondly, the design of the support roller sets reduces friction between the metering sealing pallet and the suspension plate, reducing wear and extending the service life of the equipment.

[0101] In a further preferred embodiment, the feed plate support roller assembly on the same side has two 5-6 rollers. This enhances the stability of the metering sealing plate, further reduces shaking, improves metering accuracy, and ensures the smoothness and reliability of equipment operation.

[0102] In summary, this utility model proposes a precast building component molding metering machine equipped with a pull-out metering component. This metering machine, through a unique pull-out metering component design and the ingenious coordination of the flow guide tube, suspension plate, metering sealing tray, and metering cylinder, achieves accurate metering of raw materials. This design not only improves the accuracy and stability of metering but also facilitates equipment maintenance and operation, providing strong technical support for the production of precast building components.

[0103] Please see Figures 28 to 31The compression molding machine includes a base 6-11, with columns 6-12 installed at the four corners of the base, an upper beam 6-13 installed on the upper part of the columns, a slider 6-14 installed on the columns, and a sealing mold frame 6-15 installed on the slider. The upper end of the sealing mold frame is connected to a sealing mold cavity hydraulic cylinder 6-16, and a mold core 6-17 is provided inside the sealing mold frame. The upper end of the mold core is connected to a forming hydraulic cylinder 6-18 that drives the mold core to move up and down. A movable lower mold moving assembly 6-19 is installed on the base, and a lower mold 6-191 is fixedly installed on the movable lower mold moving assembly. A guide rail 6-192 extends from the base toward the compression molding machine, and a drive cylinder 6-193 is installed at the outer end of the guide rail. The drive cylinder is connected to the lower mold moving assembly 6-194, and the lower mold moving assembly reciprocates along the guide rail under the drive of the drive cylinder. The design of the compression molding machine 1 fully considers the actual needs of template production. From the base 6-11 to the column 6-12, the upper beam 6-13, the slider 6-14, and the edge sealing mold frame 6-15, a stable yet flexible framework is formed. Driven by the edge sealing mold cavity hydraulic cylinder 6-16, the edge sealing mold frame 6-15 enables fast and accurate edge sealing operations, providing solid protection for the edges of the template and preventing cracking or damage during subsequent use. Simultaneously, the mold core 6-17 moves up and down under the drive of the forming hydraulic cylinder 6-18, ensuring precise forming of the template's internal structure and meeting the stringent requirements for template strength, flatness, and dimensional accuracy. Guided precisely by the guide rail 6-192, the lower mold reciprocates along the guide rail under the powerful push of the drive cylinder 6-193, acting like a "carrier" on a precise production line. This design primarily enables the lower mold to move back and forth between the compression metering machine and the compression molding machine, ensuring seamless material transfer from the metering machine to the molding machine. This efficient material transfer method not only improves production efficiency but also ensures the continuity and stability of template production, providing a strong guarantee for the large-scale production of non-removable composite templates for construction. The lower mold 6-191 is equipped with drainage holes 6-1910, effectively solving the problem of moisture accumulation during material pressing and filtration, ensuring smooth water drainage and avoiding impact on the template's forming quality and subsequent use. The upper surface of the lower mold is equipped with precast steel reinforcement cage positioning columns 6-1911, providing precise positioning for the internal steel reinforcement cage, ensuring the structural strength and stability of the template. This design simplifies the installation process of the steel reinforcement cage, improves production efficiency, and ensures accurate template forming. A rigid support mesh 6-1912 is laid on the upper surface of the lower mold. The laying of the rigid support mesh 6-1912, as a rigid support structure, effectively prevents the drainage holes from being blocked, avoids airtightness during pressing, and ensures smooth drainage. A filter cloth with a mesh size greater than that of the rigid support mesh (6-1913) is laid on the upper surface of the rigid support mesh to achieve the pressure filtration effect on the material.The filter cloth has a larger mesh size than the rigid support mesh, allowing for finer filtration of moisture and impurities in the material. This ensures that the material is drained away with the filtrate during placement, thereby improving the compactness of the template and the quality of the finished product. The rigid support mesh and filter cloth are mounted on the positioning column 6-1911, and both the rigid support mesh 6-1912 and the filter cloth are reusable. The lower mold moving assembly 6-194 includes a trolley 6-1941 that moves on a guide rail. A lower mold base 6-1942 is slidably mounted on the trolley. Elastic reset members 6-1943, which are elastic rubber pads, are provided around the lower mold base and on the upper surface of the trolley. The lower mold 6-191 is mounted on the upper surface of the lower mold base. A lower mold base support plate 6-195 is provided on the trolley corresponding to the lower mold base. A pallet support frame 6-196 is provided on the trolley adjacent to the automatic pallet feeding system side. A pallet support platform 6-1960 is provided on the pallet support frame, which is used to support empty pallets or pallets with non-removable composite templates. The lower mold 6-191 has drainage holes 6-1910, and the non-removable composite template precast steel reinforcement skeleton positioning columns 6-1911 are also provided. Additionally, the rigid support mesh enhances the load-bearing capacity of the bottom of the template, improving the overall stability of the template. Regarding the laying of filter cloth 6-1913, in summary, the design of the lower mold 6-191, through the integration of multiple technical features such as drainage holes, positioning columns, rigid support mesh, and filter cloth, achieves comprehensive optimization of the template forming process. This design not only improves production efficiency but also ensures the forming quality of the template and the stability of its subsequent use, providing reliable technical support for the production of non-removable composite templates for construction. To achieve the recycling of filter water, a filter water collection pool or collection box is preferably set at the bottom of the molding machine. The pallet support frame is equipped with a pallet longitudinal positioning component 6-197 and / or a flip-type transverse positioning component 6-198 adjacent to the automatic pallet stacking and feeding system side. The pallet longitudinal positioning component 6-197 includes a longitudinal positioning cylinder 6-1970, which is connected to a positioning plate 6-1971. The pallet longitudinal positioning component 6-197 adopts a cylinder-driven positioning plate design, with the positioning plate higher than the pallet height. This setting ensures accurate positioning of the pallet in the longitudinal direction. When the pallet enters or leaves the molding machine, the cylinder drives the positioning plate to quickly reach its position, effectively preventing pallet offset and wobbling, and improving production stability and accuracy. The lateral positioning component 6-198 is a flip-type lateral positioning component, including a lateral positioning cylinder 6-1980, which is hinged to a positioning post 6-1981. The positioning post extends out of the lateral positioning groove 6-1982 at the end of the pallet support platform. The flip-type lateral positioning component 6-198 achieves the flipping function of the positioning post by hinged to the positioning post by the cylinder. When the pallet exits the molding machine, the positioning post flips to the lateral positioning position under the drive of the cylinder, ensuring accurate alignment of the pallet.When pallets are supplied from the automated palletizing system, the positioning posts flip downwards to create clearance, providing space for the pallets to enter smoothly. This design not only improves production flexibility but also effectively avoids collisions and damage to the pallets during the supply process. Further preferably, a guide post 6-1990 is provided between the pallet support frame and the pallet support platform, and a return spring 6-1991 is fitted onto the guide post. This technical feature has the following technical effects: Stable support and precise positioning: The presence of the guide post ensures stable vertical movement of the pallet support platform, effectively preventing the pallet from shifting or tilting due to external forces during support, thus ensuring that empty pallets or pallets with non-removable composite templates can be accurately placed in the predetermined position. The return spring 6-1991 provides continuous elasticity, allowing the pallet support platform to automatically return to its initial position when no external force is applied. This helps maintain the stability and consistency of the entire support system and improves the accuracy of automated operations. Buffering and Pallet Protection: When the pallet is placed on the pallet support platform, the return spring 6-1991 acts as a buffer, absorbing the impact force when the pallet falls, reducing potential damage to the pallet and the non-removable composite template, and extending the service life of the pallet and template. During the operation of the automatic palletizing system, minor collisions may occur due to inaccurate mechanical movement or uneven material stacking. The elastic buffering capacity of the return spring can effectively reduce the damage of these collisions to the pallet support frame and the pallet itself. More preferably, a first protective plate 6-201 is provided around the lower mold base. More preferably, a second protective plate 6-202 is provided around the trolley. The lower mold base and / or the trolley are provided with protective plates. This technical feature effectively prevents external impurities such as mud, water, and dust from entering the sliding fit space between the lower mold base and the trolley. The first and second protective plates act as a barrier, protecting the sliding parts from contamination and wear, and extending the service life of the equipment. At the same time, it also improves the reliability of the equipment, reduces failures and maintenance costs caused by impurities, and ensures the continuity and stability of the production process.

Alternatively, it can be a cylinder, with the front end of the cylinder's piston rod serving as the driving end to rotate the pallet lifting frame. In this embodiment, a cylinder is preferred, with the end of the cylinder's piston rod hinged to the pallet lifting frame 7-5-1. L-shaped brackets 7-5-63 are provided at both ends of the pallet clamping beams. First, under the action of the pallet clamping cylinder, the beams rotate upwards to avoid the pallet, then pass over the pallet and return to their original position. The horizontal part of the L-shaped bracket 7-5-63 supports the lower surface of the pallet, thereby enabling the lifting or lowering of the finished pallet. The pallet clamping cylinder 7-5-62 drives the pallet clamping beam 7-5-61 to flip upwards to avoid the pallet. After the pallet enters the correct position, the clamping cylinder resets the clamping beam, and the horizontal part of the L-shaped bracket 7-5-63 supports the lower surface of the pallet.
