Description

Technical Field

[0001] This utility model relates to the field of anti-crack mesh fabric technology, specifically an automatic anti-crack mesh fabric laying machine for mortar construction. Background Technology

[0002] During construction, in order to prevent the cement surface from cracking, it is necessary to install wire mesh. This ensures that the cement surface will not crack after it solidifies. The wall mesh, with its high-strength material and mesh structure, can effectively enhance the overall strength of the wall, improve its load-bearing capacity and stability. At the same time, when the wall is affected by factors such as temperature changes, humidity changes, and foundation settlement, the wall mesh can buffer and disperse stress, preventing cracks from appearing on the wall surface.

[0003] Existing crack-resistant mesh fabrics are generally laid manually. First, a base coat of mortar is applied to the wall surface. Before the base coat sets, the cut mesh fabric is laid flat on top of the mortar, and then gently pressed from the center outwards with a trowel to ensure the mesh fabric is fully embedded. Finally, a layer of mortar is applied to completely cover the mesh fabric, ensuring a smooth surface with no exposed mesh fabric. This completes the mesh installation. However, traditional manual installation is slow, requires multiple people to complete the processes of coating, laying, and troweling, and is labor-intensive. In large-scale construction, labor costs increase significantly, and the construction period is extended, making it difficult to guarantee the construction schedule and increasing the risk of quality fluctuations.

[0019] Please see Figure 1-4An automatic mortar crack-resistant mesh laying machine includes a machine body 1, a lifting mechanism for lifting and laying the mesh, a lifting frame 2, and a laying mechanism on the lifting frame 2. The laying mechanism includes a support structure for supporting the mesh, an unwinding structure for uniformly unwinding the mesh, an extrusion structure for embedding the mesh into the wall mortar, and a cutting structure for cutting the mesh. The machine body 1 also includes a spraying mechanism for spraying mortar onto the laid mesh. The spraying mechanism includes a hopper 17, a screw pump 18, and a spraying end 16. The machine body 1 serves as the basic frame of the equipment, supporting and fixing all components such as the lifting mechanism, laying mechanism, and spraying mechanism to ensure the stability of the overall structure. Through the integrated operation of the lifting mechanism, laying mechanism, and spraying mechanism, the unwinding, embedding, cutting, and mortar spraying of the mesh can be completed simultaneously, reducing the time between processes. It is especially suitable for large-area construction, significantly shortening the construction period and accelerating the construction progress.

[0020] Please see Figure 1-3The machine body 1 is externally equipped with a lifting frame 2. A lead screw 3 is rotatably mounted on the lifting frame 2. A lead screw nut 4 is engaged with the lead screw 3. A mounting frame 5 is externally positioned to limit the movement of the lead screw nut 4. A drive motor 6 is mounted on the lifting frame 2, with its output end connected to one end of the lead screw 3. The support structure is a rotating roller 7 for supporting the rolled mesh fabric. The rotating roller 7 is mounted on the mounting frame 5. The unwinding structure consists of two sets of unwinding rollers 8 that can cooperate with each other. A motor 11 is mounted on one end of the unwinding roller 8. The unwinding roller 8 is mounted on the mounting frame 5 and positioned in parallel. Below the rotating roller 7, the cutting structure includes a housing 9 mounted on the mounting frame 5 and located below the unwinding roller 8. The housing 9 has a through groove 12. Inside the housing 9 are a movable cutting blade 14 and a cutting block 13 that cooperates with the cutting blade 14. Inside the housing 9 is an electrically operated telescopic column 15 whose output end is connected to the outside of the cutting blade 14. The extrusion structure is an extrusion roller 10 rotatably mounted on the mounting frame 5, located below the housing 9. The lifting frame 2 connects the machine body 1 and the lifting drive component, and is a wire... Screw 3, drive motor 6, and other components provide the mounting carrier, enabling the vertical lifting and lowering movement of the laying mechanism. Drive motor 6 outputs power to drive screw 3 to rotate, controlling the lifting speed and position of the lifting frame 2, allowing the laying mechanism to be installed on walls at different heights. Screw 3 and screw nut 4, through meshing transmission, convert the rotational motion of drive motor 6 into the linear lifting and lowering motion of mounting frame 5, realizing the height adjustment of the laying mechanism. Rotary roller 7 supports the rolled anti-crack mesh fabric, and its rotatable design allows the mesh fabric to unroll smoothly during unwinding, avoiding tangling. The two sets of unwinding rollers 8 work together and are driven to rotate by motor 11 to release the mesh fabric at a uniform speed. The unwinding speed and tension are controlled to ensure that the mesh fabric is laid flat. The extrusion roller 10 rotates to press the unfolded mesh fabric into the mortar already applied to the wall, ensuring that the mesh fabric adheres tightly to the wall and enhancing the crack prevention effect. The housing 9 and the through groove 12 provide a transmission channel for the mesh fabric, guiding the mesh fabric to the cutting position. The electric telescopic column 15 drives the cutting blade 14 to move downward, which works with the cutting block 13 to cut the mesh fabric, achieving precise control of the laying length.

[0021] Please see Figure 2 The mounting frame 5 is equipped with two sets of support frames 20. Each set of support frames 20 is equipped with multiple sets of telescopic electric support columns 24. The output ends of the telescopic electric support columns 24 are connected to the outside of the extrusion roller 10 and the spraying end 16, respectively. The support frames 20 are fixed on the mounting frame 5. The position and pressure of the extrusion roller 10 and the spraying end 16 can be adjusted by the telescopic electric support columns 24 to adapt to the needs of different construction scenarios.

[0022] Please see Figure 1 and Figure 4A hopper 17 is mounted on the machine body 1, and a screw pump 18 is located below the hopper 17. The outlet of the hopper 17 is connected to the interior of the screw pump 18. A pump head 19 is provided at the output end of the screw pump 18. An air compressor 21 is installed inside the machine body 1, and the output end of the air compressor 21 is connected to the pump head 19 through a pipe 22. A conveying pipe 23 is provided on the pump head 19, and one end of the conveying pipe 23 is connected to the spraying end 16. The hopper 17 stores the mortar raw material to be sprayed, providing a continuous supply for the spraying operation. Material supply: The screw pump 18 pressurizes and delivers the mortar in the hopper 17 to the pump head 19 through the rotation of the screw, ensuring the stability and uniformity of mortar delivery. The air compressor 21 provides compressed air, which is delivered to the pump head 19 through the pipe 22. After mixing with the mortar, it forms a high-pressure fluid, which causes the mortar to be sprayed evenly from the spray end 16. The conveying pipe 23 connects the pump head 19 and the spray end 16 to transport the mortar. The spray end 16 sprays the mortar evenly onto the surface of the laid mesh cloth, covers and fixes the mesh cloth, and completes the construction.

[0023] Working principle: The rotating roller 7 supports the rolled mesh fabric. As the drive motor 6 controls the lead screw 3 to rotate, it drives the mounting frame 5 to rise and fall along the lifting frame 2. The motor 11 drives the unwinding roller 8 to rotate at a constant speed, unfolding the mesh fabric from the rotating roller 7 and conveying it downwards. The pressing roller 10, pushed by the telescopic electric support column 24, presses the mesh fabric into the mortar already applied to the wall, ensuring a tight fit. When the preset length is reached, the electric telescopic column 15 drives the cutting blade 14 to move, cooperating with the cutting block 13 to cut the mesh fabric, completing a single laying operation. During the process, the screw pump 18 draws mortar from the hopper 17 and delivers it to the conveying pipe 23 through the pump head 19. The air compressor 21 provides compressed air, which mixes with the mortar at the pump head 19 through the pipe body 22 to form a high-pressure fluid. The mortar reaches the spraying end 16 through the conveying pipe 23 and is evenly sprayed onto the surface of the laid mesh cloth under the adjustment of the telescopic electric support column 24, covering and fixing the mesh cloth. This makes the laying of the mesh cloth more stable and allows construction workers to apply the surface layer of the mesh cloth more quickly, reducing labor costs.
