Description

Technical Field

[0001] This utility model belongs to the technical field of precast building component production equipment, and particularly relates to a molding quantitative feeder for precast building component production. Background Technology

[0002] Compression molding technology is widely used in the production of precast building components due to its high efficiency and precision. However, the key to compression molding technology lies in the accurate measurement of raw materials, as the proportions and quantities of raw materials directly affect the quality and performance of precast components. This is especially true in the production of non-removable composite formwork, where the measurement requirements for various compression molding materials are particularly stringent and must be ensured to be absolutely accurate.

[0003] Currently, existing production lines typically use equipment such as electronic scales and metering pumps to measure raw materials. While these devices meet production needs to a certain extent, they also present some significant problems. On one hand, the accuracy and stability of equipment like electronic scales and metering pumps are affected by various factors, such as the manufacturing precision of the equipment itself, wear and tear during use, and changes in ambient temperature and humidity, all of which can lead to errors in the measurement process. On the other hand, operator negligence or improper operation is also a major cause of measurement errors.

[0004] The existence of such measurement errors may not only affect the performance of the non-removable composite formwork, causing it to fail to meet design requirements, but may also negatively impact the overall quality of precast components. During use, non-removable composite formwork that does not meet performance requirements may experience cracking, deformation, and other problems, severely affecting its performance and lifespan.

[0005] Therefore, there is an urgent need for a new type of molding quantitative feeder to solve the measurement error problem existing in the prior art. This utility model provides a molding quantitative feeder for the production of precast building components. Utility Model Content

[0013] The advantages and technical effects of this utility model are as follows: This molding quantitative feeder for the production of precast building components achieves efficient, accurate and stable material metering and feeding through a carefully designed structure and optimized functional configuration.

[0014] First, the frame, serving as the supporting structure for the entire machine, ensures the stability and reliability of the equipment, providing a solid foundation for the entire feeding process. The mixing unit installed inside the receiving cylinder achieves uniform mixing of the materials, providing an accurate basis for subsequent metering and greatly improving the uniformity of material processing and overall work efficiency.

[0015] The pull-out metering assembly is ingeniously designed. Through the coordinated action of components such as the flow guide cylinder, suspension plate, and metering sealing support, precise control of the material quantity is achieved. In particular, the closed metering space formed by the metering cylinder and suspension plate ensures accurate control of the material quantity during the metering process while preventing material leakage. The introduction of the feeding cylinder makes the feeding process smoother, ensuring that the material enters the metering space smoothly while preventing material leakage from the receiving cylinder during feeding.

[0016] Furthermore, the modular design of the measuring cylinder allows the equipment to be flexibly adjusted to meet the quantitative requirements of different products without disassembling or replacing the measuring cylinder, greatly improving the adaptability and flexibility of the equipment and significantly reducing downtime and costs.

[0017] The installation of compression springs further ensures the sealing of the metering space, prevents material leakage, guarantees metering accuracy, and reduces friction and wear between components, thus extending the service life of the equipment.

[0018] In addition, the feed plate support rollers on both sides of the suspension plate provide stable support for the metering sealing plate, reducing metering errors caused by shaking and tilting, reducing wear, and further improving the stability and reliability of the equipment.

[0019] In summary, this molding quantitative feeder, through a series of innovative designs, achieves efficient, accurate, and stable material metering and feeding. It is easy to operate and maintain, greatly improving the production efficiency and product quality of precast building components, and providing strong support for the production of precast components in the construction industry.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] Please see Figures 1 to 4 A precast molding quantitative feeder for producing precast building components includes a frame 1, a receiving cylinder 2 mounted above the frame, and a mixing unit 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 materials, 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 3 mainly includes a motor bracket 3-1 installed above the receiving cylinder, on which a mixing motor 3-2 is mounted. The mixing motor has mixing blades 3-3. A discharge port 2-1 is installed at the lower end of the receiving cylinder. A pull-out metering component 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 4-1 positioned on the bottom plate of the receiving cylinder corresponding to the discharge port. A suspension plate 4-2 is fixedly mounted on the lower end face of the guide cylinder. A metering sealing support plate 4-3 is connected to the lower part of the suspension plate via a suspension rod. A feeding plate 4-4 is located on the lower surface of the suspension plate. The front end of the feeding plate is a metering area 4-40, and the rear end is a sealing area 4-41. A metering cylinder 4-5 is located 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 metering. The metering cylinder corresponds to the discharge port, ensuring smooth entry of material into the metering space and improving the efficiency and accuracy of metering. The sealing zone is connected to a feeding cylinder 5, which is fixedly connected to a receiving cylinder 2. During material receiving, the metering cylinder aligns with the discharge port. When feeding, the feeding cylinder extends, pushing the metering sealing plate forward, gradually transitioning from the metering zone to the sealing zone, thus ensuring that material does not leak from the receiving cylinder while feeding. This equipment not only accurately measures the amount of material 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.

[0026] More preferably, a movable measuring cylinder 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 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.

[0027] In a further preferred embodiment, a compression spring 4-8 is installed on the suspension rod below the metering sealing tray 4-3. The compression spring-type 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 can also reduce 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.

[0028] More preferably, the suspension plate is provided with feed plate support roller groups 6 on both sides. The support roller groups 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 groups reduces friction between the metering sealing pallet and the suspension plate, reducing wear and extending the service life of the equipment.

[0029] In a further preferred embodiment, two feed plate support rollers are provided on the same side. This enhances the stability of the metering sealing plate, further reduces shaking, improves metering accuracy, and ensures the smoothness and reliability of equipment operation.

[0030] 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.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
