Abstract

This invention discloses a filling device and method for composite dry-fillable masonry blocks, relating to the field of building material production equipment technology. It overcomes the defects of existing dry-filling methods, such as air gaps and loose internal structure. The device includes a filling line for conveying masonry blocks. Above the line, along the conveying direction, a filling mechanism, a pressing and compacting mechanism, and a surface leveling mechanism are sequentially arranged. The filling mechanism is used to inject material into the filling port of the masonry block; the pressing and compacting mechanism is used to press down the material inside the masonry block; and the surface leveling mechanism is used to scrape off and level the excess material on the surface. Its innovation lies in the placement of a vibration mechanism below the filling line, corresponding to the pressing and compacting mechanism, forming a composite compaction mode of "upper pressure and lower vibration." This effectively promotes the flow and dense filling of the filling material inside the masonry block, completely eliminating internal air gaps. This invention integrates filling, compaction, and leveling functions, achieving continuous automated production and significantly improving the filling quality and production efficiency of the masonry blocks.

Description

Technical Field

[0001] This invention relates to the field of building material production equipment technology, specifically to an automated grouting device for dry filling, compaction, and surface leveling of the internal cavities of composite blocks. Background Technology

[0002] Composite blocks are a common building wall material, typically with an internal cavity structure. To improve their thermal insulation, sound insulation, or load-bearing performance, the internal cavity of the block needs to be filled with dry, semi-dry, or wet filler materials such as foamed concrete, insulating granules, or lightweight aggregate concrete.

[0003] Currently, the filling processes for these types of blocks often suffer from the following problems: First, simple pouring methods easily create air gaps and voids inside the blocks, resulting in incomplete filling and affecting the final performance of the blocks; second, the internal material is loose after filling, and if not compacted, it may settle during transportation and use, leading to upper cavities; third, excess material usually remains on the surface of the blocks after pouring, requiring subsequent cleaning, which increases production steps and costs. Existing technologies lack an automated device that integrates pouring, efficient air venting and compaction, and surface treatment, making it difficult to meet the demands for high-quality and high-efficiency production.

[0004] Therefore, there is an urgent need for a grouting device that can achieve continuous operation, ensure that the filling material is dense and uniform inside the block, and automatically complete the surface cleaning. Summary of the Invention

[0005] The primary objective of this invention is to overcome the shortcomings of the prior art and provide a grouting device for composite block dry fillable materials that is highly automated, has a dense filling effect, and a clean surface finish.

[0006] The second objective of this invention is to provide a method for pressurizing composite block dry fillable materials.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A filling device for composite block dry fillable material includes a filling line for conveying blocks, the key feature of which is that the filling line is provided with the following components arranged sequentially above it along its conveying direction:

[0009] A filling mechanism for injecting the fillable material into a filling port on the upper surface of the block;

[0010] The downward compaction mechanism is located downstream of the filling mechanism and is used to press down the filling material inside the block to eliminate internal air gaps and perform preliminary compaction.

[0011] A surface leveling mechanism, located downstream of the pressing and compacting mechanism, is used to scrape off and level the excess fillable material on the surface of the block.

[0012] A vibration mechanism is provided below the filling line, corresponding to the position of the pressing and compacting mechanism. The vibration mechanism works in conjunction with the pressing and compacting mechanism to promote the flow and compaction of the fillable material inside the block.

[0013] Furthermore, the filling mechanism includes a filling funnel located at the upper part of the filling line, the outlet of the filling funnel being aligned with the upper filling port of the block; the upper surface of the block is provided with a filling groove, and the bottom of the filling groove is provided with a filling hole communicating with the filling port of the block.

[0014] Furthermore, the filling tank is elongated and has a flared cross-section with a gradually widening opening. This flared structure facilitates the guidance of material in and prevents spillage.

[0015] Furthermore, the vibration mechanism is a vibration conveyor, which is supported below the filling line, and its vibration transmission surface is in close contact with the conveying surface of the filling line or connected by a component.

[0016] Furthermore, at least one vibration pump is provided inside or outside the vibrating conveyor to provide a vibration source.

[0017] Furthermore, the pressing and compaction mechanism includes a pressing drive component and a pressing head assembly connected to its lower part. The pressing head assembly has multiple protrusions adapted to the shape of the internal cavity of the block. These protrusions can extend into each individual cavity of the block for precise compaction.

[0018] Furthermore, the pressing and compacting mechanism also includes a limiting component for limiting the block when the pressing drive component presses down, so as to prevent the block from shifting or being damaged when compressed.

[0019] Furthermore, the limiting component includes a limiting stop bar disposed at the end of the pressing drive component, and / or extrusion plates disposed on both sides thereon for laterally clamping the block.

[0020] Furthermore, the surface leveling mechanism includes a mounting frame, rotatable rollers mounted on the mounting frame, and a scraper positioned in front of or behind the rollers for contacting the surface of the block. The rollers can roll and level slightly raised surfaces, while the scraper is responsible for removing most of the excess material.

[0021] A method for filling composite blocks with dry fillable material using the aforementioned filling device, comprising the following steps:

[0022] S1, Feeding and Filling: The blocks are conveyed by the filling line. When the blocks move to the bottom of the filling funnel, the material falls into the filling tank through the discharge port and enters the internal cavity of the blocks through the filling hole.

[0023] S2, Vibration and Compaction: After the grouting is completed, the block continues to move forward to the compaction station. This station is formed by the combined action of the upper compaction mechanism and the lower vibration mechanism. The high-frequency micro-amplitude vibration is generated by the built-in or external vibration pump. This vibration is transmitted to the block on it through the closely contacting conveyor surface. The upper pressing drive component drives the pressing head assembly to move downward. The bottom of the pressing head assembly has multiple protrusions that correspond one-to-one with each cavity inside the block. These protrusions are inserted into the cavities to directly press down the filler. The end of the pressing drive component is equipped with a limit stop bar, and movable extrusion plates are set on both sides to clamp the block from the side before or during the pressing head assembly to prevent it from moving or tilting.

[0024] S3, Scraping and Rolling: After compaction, the blocks enter the surface leveling station. The surface leveling mechanism includes a mounting frame that spans the filling line. The mounting frame is equipped with freely rotating rollers. A scraper is set in front of or behind the rollers. When the block passes through, a cylinder is set on the upper part of the hard scraper, which presses against the surface of the block to scrape away most of the excess material on the surface of the block. Subsequently, the rollers roll over any slight bumps that may exist, finally making the upper surface of the block flat and smooth.

[0025] S4, Curing or Packaging: After the blocks have undergone the above processes, and provided that their internal filling is dense and their appearance is neat, they can be directly transferred to the curing or packaging stage.

[0026] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0027] 1. Integration and Automation: By connecting the three processes of filling, compaction and leveling in a series through the filling line, continuous automated production is achieved, which significantly improves production efficiency;

[0028] 2. High filling density: It creatively combines "top pressure and bottom vibration". The bottom pressure compaction mechanism squeezes the material from the top, while the bottom vibration mechanism rearranges the filling material particles and enhances the fluidity through vibration. The two work together to effectively remove internal air, so that the filling reaches extremely high density and avoids voids and settlement.

[0029] 3. Excellent surface treatment effect: The surface leveling mechanism can scrape and finely level the upper surface of the block immediately after filling and compaction, so that the block has a clean appearance when it leaves the factory, eliminating the need for subsequent cleaning and saving manpower and costs;

[0030] 4. Highly targeted structure: The pressure head assembly is adapted to the shape of the block cavity, achieving precise compaction; detailed designs such as the flared filling groove and limiting components further ensure the accuracy of the grouting process and the stability of the production process.

[0031] 5. The filling and pressing method of the present invention, through filling, compaction, scraping and rolling, not only improves the overall quality of composite blocks, but also saves the maintenance time of composite blocks due to the use of dry filling materials, and can greatly save storage space and improve turnover efficiency.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1 , Figure 2 As shown, the present invention provides a filling device for a composite block dry fillable material, the core of which is a continuously operating filling line 7, on which blocks 10 are placed in sequence and transported through each station.

[0039] First, the blocks 10 are conveyed to the bottom of the filling mechanism. The filling mechanism mainly includes a filling funnel 1 that stores dry fillable materials (such as lightweight concrete mix). Figure 3 As shown, the upper surface of the block 10 is pre-formed with a filling groove 5, which is preferably elongated and has a V-shaped or U-shaped flared cross-section to facilitate material reception. A filling hole 6 is opened at the bottom of the filling groove 5, which communicates with the complex cavity inside the block 10. When the block 10 moves to below the filling funnel 1, the material falls into the filling groove 5 through the discharge port and enters the internal cavity of the block 10 through the filling hole 6.

[0040] After the grouting is completed, the block 10 continues to the lower compaction station. This station is formed by the combined action of the upper lower compaction mechanism and the lower vibration mechanism. The lower vibration mechanism is preferably a vibrating conveyor 2, which generates high-frequency micro-amplitude vibrations through a built-in or external vibrating pump 8. This vibration is transmitted to the block 10 on it through the closely contacting conveyor surface. At the same time, as Figure 4 As shown, the upper pressing drive component 4 (which can be a cylinder, hydraulic cylinder, or electric push rod) drives the pressing head assembly 9 to move downwards. The bottom of the pressing head assembly 9 has multiple protrusions, the shape, size, and distribution of which correspond one-to-one with the cavities inside the block 10, allowing it to be inserted into the cavities to directly press down the filler material. To ensure the stability of the block 10 during pressing, a limiting stop 11 can be provided at the end of the pressing drive component 4, and movable extrusion plates 12 can be provided on both sides to clamp the block 10 from the side before or during pressing down, preventing it from moving or tilting. Under the synergistic effect of this "static pressing" and "dynamic vibration," the friction between the filler material particles is effectively overcome, the material flows fully to fill every corner, and internal air is completely expelled, achieving initial compaction and curing.

[0041] After compaction, the surface of the block 10 may have excess material or be uneven due to compression. The block 10 then proceeds to the surface leveling station. See [link / reference]. Figure 1 , Figure 2 The surface leveling mechanism includes a mounting frame 3 spanning the filling line 7. The mounting frame 3 is equipped with freely rotating rollers 13. To enhance the rolling force of the rollers 13, a cylinder can be installed on the mounting frame 3, acting on the rollers 13 to provide sufficient rolling force to act on the surface of the block 10, thus leveling off excess fillable material. A scraper 14 is positioned in front of or behind the rollers 13. As the block 10 passes, the rigid scraper 14, with a cylinder on its upper part, abuts against the surface of the block 10 to prevent it from being lifted, scraping away most of the excess material from the surface of the block 10. Subsequently, the rollers 13 roll over any slight bulges that may exist, ultimately making the upper surface of the block smooth and flat.

[0042] After the above processes, the block 10 is densely filled and has a clean appearance. It can be directly transferred to the curing or packaging stage, or the above steps can be repeated to ensure that the product filling quality meets the expected requirements, thus completing the entire process from filling to finished product.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
