Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a fiber mesh spraying device for auxiliary coating spraying of building exterior wall insulation and paint spraying. Background Technology

[0002] In modern building construction, external wall insulation systems are a crucial component for achieving building energy conservation. During the construction of the insulation and coating layers, to prevent surface cracking and enhance the tensile strength and impact resistance of the protective layer, a layer of reinforcing fiber mesh is typically laid on the outside of the insulation layer before subsequent coating or surface mortar application.

[0003] Currently, the installation of this type of fiber mesh fabric relies almost entirely on manual labor. Workers first need to apply a layer of polymer mortar to the wall, then unfold and cut the pre-made roll of mesh fabric, quickly lay it flat and press it into the wet mortar, and finally level it.

[0004] This traditional construction method has obvious shortcomings: First, the entire process (applying, cutting, laying, pressing, and leveling) relies entirely on manual labor, resulting in cumbersome steps, low efficiency, and high labor intensity, making it unsuitable for large-scale, rapid construction. Second, the quality of manual laying is highly dependent on the worker's skill level, making it difficult to ensure that the depth and flatness of the mesh fabric are completely uniform. This can easily lead to defects such as hollow areas, wrinkles, or improper overlaps, thus affecting the overall stability and crack resistance of the exterior wall system.

[0005] In response to the aforementioned related technologies, this utility model proposes a fiber mesh spraying device to assist in building exterior wall insulation and paint spraying, thereby overcoming the shortcomings of the existing technology. Utility Model Content

The first drive plate 309 is provided with a mounting hole 312.

[0040] The implementation principle of this application embodiment is as follows:

[0041] Firstly, during use, the drive mechanism 1 is installed and fixed on the exterior wall of the building. The multiple columns 101 of the drive mechanism 1 are connected by a horizontal column 103. The lifting wheels 105 at both ends of the horizontal column 103 rotate and move up and down in the first slide rail 102 of the column 101. The groove 403 of the base assembly 4 is engaged on the second slide rail 104 fixedly connected above the horizontal column 103. The drive wheel 402 rotates inside the second slide rail 104, thereby driving the second base 401 to move left and right. Through the up and down movement of the lifting wheel 105 and the left and right movement of the drive wheel 402, the base assembly 4 is positioned over a wide range on the wall facade.

[0042] After positioning, when it is necessary to adjust the orientation of the equipment, the first motor 407 of the base assembly 4 is started. The first motor 407 drives the first drive gear 406 to rotate. The first drive gear 406 meshes with the first main gear 405, thereby driving the first main gear 405, which is fixedly connected to the base plate 601, to rotate. Since the housing 404 is rotatably connected above the second base 401, this structure realizes the rotation of the base plate 601, i.e. the entire moving assembly 6, relative to the base assembly 4, to adjust the spraying orientation.

[0043] Before spraying, a heat-absorbing material, such as silicon carbide, is applied to the wall surface to effectively assist the high-temperature glass fiber in cooling and solidification. Then, the glass fiber particles are placed into the heating hopper 201 of the heating supply assembly 2. The heating hopper 201 is slidably mounted inside the first groove 205 of the first mounting plate 204 via a T-shaped guide rail 202 and supported by the first base 203. After the particles are heated and melted inside the heating hopper 201, they are fed into the dispensing hopper 508 of the spraying assembly 5. The second motor 503 is started, driving the second main gear 506 to rotate. The second main gear 506 meshes with and drives the second drive gear 507. Since the second drive gear 507 is fixedly connected to the feed pipe of the high-temperature resistant ceramic nozzle 505, and the surface of the high-temperature resistant ceramic nozzle 505 is provided with an anti-sticking coating, the high-temperature resistant ceramic nozzle 505 is driven to rotate. The head 505 rotates at high speed; the molten material is sprayed from the distribution bin 508 through the high-temperature resistant ceramic nozzle 505. The size of the orifice of the high-temperature resistant ceramic nozzle 505 ensures that the sprayed glass fiber can be drawn into fine filaments by the high-speed airflow. By controlling the distance between the high-temperature resistant ceramic nozzle 505 and the wall, the flight distance of the molten glass fiber from the high-temperature resistant ceramic nozzle 505 to the wall is extended, allowing it more time to exchange heat with the air before impacting the wall. Combined with the heat-absorbing coating pre-coated on the wall, it can cool down rapidly after contact with the building wall. The orifice on the high-temperature resistant ceramic nozzle 505 is a conical orifice with a small inlet and a large outlet, forming a gradually expanding flow channel, effectively preventing the probability of blockage. For areas such as inside corners, supplementary spraying is carried out through the vertical fixed nozzle 502 and the horizontal fixed nozzle 504, which are both connected to the distribution bin 508.

[0044] During the spraying process, the second drive plate 603 can be pushed to slide in the second slide groove 602 of the base plate 601 by the third electric push rod 604, so as to realize the overall back-and-forth movement of the spraying assembly 5; at the same time, the spraying assembly 5 can be driven to move back and forth relative to the second drive plate 603 by the second electric push rod 501 to expand the adjustment range; when it is necessary to install auxiliary tools such as baffles or grinding blades, the robotic arm assembly 3 is started, and the chassis 301 connected above the second drive plate 603, the first swing arm 304 driven by the first swing motor 302, the second swing arm 305 driven by the second swing motor 303, and the second mounting plate 307 driven by the third swing motor 306 are rotated to move the end of the robotic arm to the target position; then the first electric push rod 308 drives the first drive plate 309 (which slides in the limiting groove 310 through the limiting plate 311) to move up and down, and the mounting holes 312 on the first drive plate 309 are used to realize the installation and operation of tools.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
