Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to an automated spraying equipment for building walls. Background Technology

[0002] Building wall spraying is a key process in building decoration and exterior wall protection projects. Its construction quality directly affects the aesthetics, durability, and overall efficiency of the wall.

[0003] Traditional manual spraying relies mainly on operators holding spray guns by hand. Workers need to hold heavy spray guns for long periods of time and move them repeatedly. This not only leads to huge physical exertion but also slows down the spraying speed and makes the overall construction cycle long. In addition, the uniformity of manual spraying depends entirely on the operator's experience and skill. During the construction process, factors such as worker arm fatigue, uneven movement speed, and fluctuations in the distance and angle between the spray gun and the wall can easily cause quality problems such as uneven coating thickness, runs, orange peel, or even missed spraying, which seriously affect the appearance and protective effect.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an automated spraying equipment for building walls.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0026] like Figures 1 to 5 As shown, an automated building wall spraying device according to one embodiment of the present invention includes a support 1 and a feeding device. A transmission belt 3 is installed on the support 1 via a rotating roller 2. A first drive motor is provided on the support 1. The output end of the first drive motor is fixedly connected to the input end of one of the rotating rollers 2 for driving the transmission belt 3. A connecting frame 4 is fixedly connected to the transmission belt 3. An adjustable spray gun 5 is installed on the connecting frame 4. A first electric telescopic rod 6 is hinged to the connecting frame 4. The other end of the first electric telescopic rod 6 is hinged to the spray gun 5.

[0027] The first drive motor drives the active roller 2 to rotate, causing the transmission belt 3 surrounding the two rollers 2 to move continuously. During this process, the connecting frame 4, which is fixedly installed on the transmission belt 3, moves back and forth horizontally with the spray gun 5, forming a transverse spraying path. Furthermore, by extending and retracting the first electric telescopic rod 6, the spray gun 5 can be pushed to rotate around the hinge point, thereby flexibly changing the spray angle of the paint, which enables multi-angle spraying operations.

[0028] The support frame 1 includes two movable frames 101, each of which is slidably connected to a lifting frame 102. A second electric telescopic rod 103 is fixedly connected to each movable frame 101, and the top end of each second electric telescopic rod 103 is fixedly connected to the lifting frame 102 for driving the lifting frame 102 to move vertically. In this way, the components mounted on the lifting frame 102 and the spray gun 5 can be raised or lowered as a whole.

[0029] Two rollers 2 are provided, both rotatably connected to the lifting frame 102. These two rollers 2 support and drive the transmission belt 3. Guide rollers 15 are rotatably connected to both movable frames 101, and are located inside the transmission belt 3 to tension it. This effectively prevents the transmission belt 3 from slipping or deviating during operation.

[0030] Both mobile frames 101 are equipped with casters 104, allowing the equipment to be easily moved around the construction site or workshop. A sleeve 105 is installed between the two mobile frames 101, and a set of connecting rods 106 is slidably connected inside each sleeve 105. The ends of each set of connecting rods 106 that are furthest apart are fixedly connected to the mobile frame 101. Each sleeve 105 is threaded with a locking bolt 107 for securing the connecting rods 106. The sleeve 105 connecting the two mobile frames 101 and the connecting rods 106 form a telescopic crossbeam. By pulling the connecting rods 106 outward or pushing them inward, the distance between the two mobile frames 101 can be flexibly adjusted to adapt to walls or construction spaces of different widths. After adjusting to the appropriate width, tightening the locking bolts 107 secures the equipment, ensuring its stability during operation.

[0031] Each of the two movable frames 101 is fixedly connected to a fixed frame 13. Each fixed frame 13 is threaded with two support screws 14. The bottom end of each support screw 14 is fixedly connected to an anti-slip seat, and the top end of each support screw 14 is fixedly connected to a turntable. When the equipment moves to the designated work position, the operator rotates the turntable, causing the support screws 14 to screw downwards into the threaded holes of the fixed frame 13, firmly pressing the anti-slip seats at their bottoms onto the ground. This makes the entire equipment a stable working platform.

[0032] The feeding device includes a material tank 8, inside which a conveying pump is installed. The output end of the conveying pump is fixedly connected to a feeding pipe 7, and the other end of the feeding pipe 7 is connected to the input end of the spray gun 5. After the conveying pump built into the material tank 8 is started, it can continuously pump out the paint in the tank. The paint is transported to the spray gun 5 through the feeding pipe 7 and then sprayed outward.

[0033] Many coatings experience pigment and filler sedimentation and liquid separation when left to stand. Therefore, a mixing device 11 is installed on the material tank 8. The mixing device 11 includes a second drive motor 1101 fixedly mounted on the material tank 8. A rotating shaft 1102 is fixedly connected to the output end of the second drive motor 1101, and multiple stirring blades 1103 are fixedly connected to the rotating shaft 1102. Both the rotating shaft 1102 and the stirring blades 1103 are located inside the material tank 8. In use, starting the second drive motor 1101 drives the rotating shaft 1102 and the stirring blades 1103 to rotate, thereby shearing and mixing the coating to make it uniformly suspended in the liquid medium.

[0034] A feeding port is fixedly connected to the material tank 8, and a sealing head 9 is installed inside the feeding port. A discharge pipe 10 is fixedly connected to the bottom of the material tank 8, and a control valve is installed on the discharge pipe 10. Operators can add paint to the material tank 8 through the feeding port. The sealing head 9 can prevent foreign matter from falling in and paint from evaporating. The discharge pipe 10 can be used to empty and clean the material tank 8 after the operation is completed, making it convenient to change to different colors or types of paint.

[0035] A horizontal plate 12 is fixedly connected to both sleeves 105, and the feeding device is fixedly connected to the horizontal plate 12. This allows the feeding device and the horizontal plate 12 to be integrated into one unit, making the device more integrated.

[0036] Working principle: In use, the equipment is moved to a suitable position in front of the wall to be sprayed by the moving wheels 104. By adjusting the extension and retraction of the connecting rod 106 inside the sleeve 105, the distance between the two moving frames 101 can be adjusted to adapt to different spraying operations. Then, the turntable on the fixed frame 13 is rotated, driving the support screw 14 to move downward, so that the anti-slip seat at the bottom is pressed tightly against the ground, thereby stably supporting the entire equipment and preventing it from moving during spraying. Next, the second electric telescopic rod 103 is activated to adjust the working height of the lifting frame 102, realizing the synchronous vertical lifting and lowering of the transmission belt 3 and the spray gun 5, so that the equipment can adapt to different spraying operations. For walls of different heights, during spraying, the paint is pumped from the material tank 8 by a delivery pump and continuously and stably delivered to the spray gun 5 through the delivery pipe 7. During the spraying process, the first drive motor is started to drive the rotating roller 2 to rotate, which drives the transmission belt 3 and the spray gun 5 to reciprocate in the horizontal direction. At the same time, by controlling the extension and retraction of the first electric telescopic rod 6, the pitch angle of the spray gun 5 is adjusted, thereby changing the direction of paint spraying. In addition, the second drive motor 1101 drives the rotating shaft 1102 and the stirring blade 1103 to rotate in the material tank 8 to continuously stir the paint, prevent pigment sedimentation, and ensure that the paint concentration is uniform.
