Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to a device for spraying exterior wall thermal insulation and sound insulation paint. Background Art

[0002] In the construction industry, exterior wall insulation and soundproofing are key to improving building comfort and energy efficiency. Traditional exterior wall insulation and soundproofing processes often rely on multiple independent devices and cumbersome manual operations.

[0003] During the wall pretreatment stage, wall smoothness is typically achieved using handheld sanding tools, such as sandpaper grinders or small electric sanders. These tools are not only inefficient but also struggle to ensure uniform flatness across large wall surfaces. Due to the lack of precise detection and automated control mechanisms, workers rely solely on experience and visual inspection to detect unevenness. This can lead to over-sanding or missing unpolished areas, severely impacting the adhesion of subsequent thermal and sound insulation coatings and overall construction quality.

[0004] During the paint spraying process, common spray equipment is limited in functionality and can only spray paint, without the ability to effectively recycle excess paint. This not only results in a large amount of paint waste and increases construction costs, but the uncontrolled flow of waste paint also pollutes the construction site environment, which is inconsistent with the environmental protection concept of modern green building construction.

[0005] Furthermore, the large amount of dust generated during the grinding process permeates the construction site, not only endangering the health of construction workers, such as causing respiratory diseases, but also causing serious dust pollution in the surrounding environment, affecting the quality of life and ecological environment of surrounding residents. Furthermore, traditional spray equipment typically relies on an external air pressure source, which consumes a lot of energy and makes it difficult to ensure air pressure stability, which can easily lead to problems such as uneven spray thickness and unstable coating quality.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Please see the attached Figure 1 - Attachment Figure 8The embodiment of the present invention provides an exterior wall thermal insulation and sound insulation paint spraying device, including a base 1 and a high-pressure pump, a turntable 2 is embedded and fixed on the upper part of the base 1, the rotating surface of the turntable 2 is fixedly connected to a slide rail 3, and two symmetrical brackets 4 are slidably connected to the upper part of the slide rail 3, and the two brackets 4 are respectively connected to the side walls of the slide rail 3 through a cylinder 5, one of the brackets 4 is installed with a grinding device, and the other bracket 4 is installed with a spraying device, a lifting platform 6 is fixedly connected to the bottom of the base 1, and a walking device 7 is provided at the bottom of the lifting platform 6, the grinding device includes a grinding unit 8 and a detection unit 9, wherein the grinding unit 8 is used to grind the wall surface, and the detection unit 9 is used to detect the flatness of the wall surface, and the spraying device includes a spraying unit 10 And the paint recovery unit 11, wherein the spraying unit 10 is used to spray the paint evenly on the wall, and the paint recovery unit 11 is used to scrape the paint on the wall smooth and recover excess paint. The high-pressure pump is provided with two air inlets and two exhaust parts, and is respectively provided with a valve. One of the air inlets is connected to the polishing unit 8, and a filter is provided between the two. The dust generated in the process of polishing the wall by the polishing unit 8 is recovered by air extraction by the high-pressure pump. The other air inlet is connected to the paint recovery unit 11, and the excess paint is recovered by vacuuming the air by the high-pressure pump to generate negative pressure. One of the exhaust parts is connected to the pressure supply tank of the sprayer to increase the internal air pressure of the pressure supply tank, and the other exhaust part is directly connected to the outside world.

[0027] This device integrates a polishing device and a spraying device, providing the functions of polishing, flatness detection, spraying, and paint recovery. The detection unit 9 allows for smoothness detection of the polished wall surface. The single-point detection feedback mode accurately detects uneven areas on the wall surface. Combined with the synchronous movement of the polishing unit 8, this achieves a fixed-point polishing effect, quickly smoothing uneven areas on the wall and improving polishing efficiency. Furthermore, the detection unit 9 can be used to detect the distance between the device and the wall surface, facilitating control of the polishing depth and spraying distance. Furthermore, the paint recovery unit 11 and the high-pressure pump allow excess paint to be recycled after spraying, eliminating the problem of paint waste. Furthermore, the polishing unit and the high-pressure pump allow for the recovery of dust generated during polishing, preventing dust pollution. The high-pressure airflow generated by the high-pressure pump after recovering paint and dust is then fed into the sprayer's pressure tank, increasing the internal pressure of the pressure tank and providing pressure power for subsequent spraying, thereby reducing energy consumption.

[0028] The grinding unit 8 includes a screw linear guide 801, the movable end of the screw linear guide 801 is fixedly connected to a grinder 802, the outer cover of the grinder 802 is provided with a dust hood 803, and the edge of the opening of the dust hood 803 is provided with dense brushes 804. The grinding end of the grinder 802 is located between the brush 804 and the opening of the dust hood 803, and the internal chamber of the dust hood 803 is connected to the air inlet of the filter through the dust suction pipe 805.

[0029] The linear guide 801, acting as the driving element for the sander 802, precisely controls its position and trajectory. When the sanding device begins operating, the linear guide 801 receives commands from the controller and moves the sander 802 toward the wall. The sander 802 can utilize a rotating sanding disc or a vibrating sanding head, whose high-speed rotation or vibration effectively removes uneven surfaces.

[0030] The densely packed brushes 804 at the edge of the opening of the dust hood 803 not only perform the initial cleaning of dust and debris from the wall, but also, to a certain extent, prevent dust generated by grinding from being blown away. When the sander 802 sands the wall, the generated dust is sucked into the filter through the dust suction pipe 805 under the action of the negative pressure inside the dust hood 803. The filter can effectively filter out large particles of impurities in the dust, preventing them from clogging or damaging the subsequent high-pressure pump and recovery system. The relatively pure air after filtration then enters the high-pressure pump and participates in the air pressure circulation system of the entire device.

[0031] The detection unit 9 includes a base 901, the outer wall of the base 901 is fixedly connected to one of the brackets 4, the outer wall of the screw linear guide 801 is embedded in and fixedly connected to the lower part of the base 901, and a plurality of evenly arranged grooves 902 are provided in the upper part of the base 901. A detection rod 903 is slidably connected in the groove 902, one end face of the detection rod 903 is connected to the inner end face of the groove 902 by a spring 904, and the other end face of the detection rod 903 is fixedly connected to a roller 905. A sliding rheostat 906 is fixedly connected to the upper part of the groove 902, and the outer wall of the detection rod 903 is fixedly connected to the slider end of the sliding rheostat 906. The detection unit 9 also includes a controller, a signal receiving end of the controller is communicatively connected to the signal transmitting end of the sliding rheostat 906, and the controller determines the extension length of each detection rod 903 according to the received resistance signal and controls the operation of the screw linear guide 801 and the grinder 802. When the cylinder 5 drives the grinding device to move toward the wall, the roller 905 first contacts the wall.

[0032] When the device begins operating, cylinder 5 drives the polishing device (including the detection unit) toward the wall, and roller 905 first contacts the wall. Due to variations in wall flatness, roller 905 rolls up and down with the wall's undulations, thereby driving detection rod 903 to slide within groove 902. For example, when roller 905 encounters a protrusion on the wall, detection rod 903 is pushed into groove 902, compressing spring 904. Conversely, when it encounters a depression on the wall, spring 904 pushes detection rod 903 out of groove 902.

[0033] As the detection rod 903 slides, the position of the slider of the connected sliding rheostat 906 changes, causing the resistance of the sliding rheostat 906 to change. These resistance change signals are transmitted in real time to the signal receiving end of the controller. The controller processes and analyzes the received resistance signals according to a pre-set program and algorithm to determine the extended length of each detection rod 903.

[0034] Based on the extension length information of the detection rod 903, the controller can further infer the flatness of the wall. If the extension length of the detection rod 903 in a certain area is obviously inconsistent, it means that the wall in that area is uneven. At this time, the controller will issue an instruction to control the movement of the moving end of the screw linear guide 801, so that the grinder 802 can be accurately positioned to the uneven place, and the grinder 802 can be started to perform the grinding operation. During the grinding process, the detection unit 9 continuously monitors the condition of the wall, and the controller adjusts the grinding parameters of the grinder 802, such as grinding force, grinding time, etc., according to the continuously updated detection data until the flatness of the wall in that area reaches the preset standard.

[0035] For example, if the extension length of a certain detection rod 903 is significantly smaller than that of other detection rods 903, it indicates that there is a protrusion on the wall at that location. The controller will immediately control the screw linear guide 801 to drive the grinder 802 to move to that location and start the grinder 802 to grind the protrusion. During the grinding process, the detection unit 9 continuously monitors the changes in the flatness of the wall at that location. When it detects that the flatness of the wall at that location reaches the preset standard, the controller stops the operation of the grinder 802 and controls the grinder 802 to continue moving to the next uneven area for grinding.

[0036] At the same time, through the coordinated operation of multiple detection rods 903, the overall inclination and curvature of the wall can also be detected, providing more accurate parameter basis for subsequent spraying work. For example, if the wall has a large inclination, the controller can adjust the spraying angle of the spray device to ensure that the paint can be evenly covered on the wall.

[0037] The spraying unit 10 includes a spraying main pipe 1001, and a plurality of evenly distributed nozzles 1002 are provided on one side of the spraying main pipe 1001, and the two are connected. The other side of the spraying main pipe 1001 is connected to the output end of the sprayer. The paint is output from the sprayer to the spraying main pipe 1001 and finally sprayed out by the nozzle 1002.

[0038] The main spray pipe 1001 of the spray unit 10 serves as a paint delivery channel, evenly distributing the paint output from the sprayer to each nozzle 1002. The design and layout of the nozzles 1002 have been carefully optimized to ensure that the paint is sprayed onto the wall at the appropriate angle, flow rate, and atomization level, thereby achieving a uniform and efficient spraying effect.

[0039] The paint recovery unit 11 includes a recovery box 1101, and the spray main pipeline 1001 is located in the upper part of the recovery box 1101. The upper part of the recovery box 1101 is provided with an upward inclined opening facing the wall, and the cross-section of the opening is fixedly connected to a scraper 1102 and is parallel to the wall. The lower part of the recovery box 1101 gradually converges toward the middle thereof to form a slope structure. The bottom of the recovery box 1101 is the lowest point of the slope and is connected to the recovery tank through a recovery pipeline 1103.

[0040] The paint recovery unit 11's recovery bin 1101 plays a key role in the spraying process. After the spray nozzle 1002 sprays paint onto the wall, excess paint flows down the wall and into the recovery bin 1101. A scraper 1102 on top of the recovery bin 1101 smoothes the paint, evenly distributing it and collecting excess paint into the recovery bin 1101.

[0041] The sloped structure at the bottom of recovery bin 1101 facilitates centralized collection of paint. Under the influence of gravity, the paint flows along the slope to the lowest point at the bottom of recovery bin 1101, then flows through recovery pipe 1103 into a recovery tank. The recovery tank allows for temporary storage and preliminary processing of the recovered paint, such as filtering out impurities and bubbles, to facilitate subsequent reuse.

[0042] Throughout the entire process, the high-pressure pump works closely with the paint recovery unit 11. By creating negative pressure in the recovery tank, which is then connected to the recovery box 1101, the high-pressure pump extracts excess paint from the recovery box 1101, improving paint recovery efficiency. Simultaneously, the high-pressure airflow generated during the paint recovery process is directed into the sprayer's pressure supply tank, providing additional air pressure power to the sprayer, reducing its reliance on external air sources and lowering energy consumption.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
