Description

Technical Field

[0001] This utility model relates to the field of coating spraying technology, and in particular to an automatic spraying device for heat insulation coating. Background Technology

[0002] In existing technologies, wall insulation coatings are a new type of coating that integrates reflection, radiation, and barrier functions, also known as nano-insulation coatings for walls. They achieve high reflectivity of visible and near-infrared light in the 400-2500nm range, and utilize materials such as nano-hollow microspheres to reduce thermal conductivity (up to 0.04W / mK) to block heat conduction, achieving a thermal reflectivity of over 90% and a heat insulation efficiency of approximately 90%.

[0003] A search revealed Chinese patent application number 202422827485.3, which discloses an automatic spraying device for heat-insulating transparent coating on high-rise glass. Through the coordinated use of a suspension mechanism and a drive mechanism, and by utilizing ropes to stably lower the vehicle body, the device further increases stability during descent, improving operational reliability and safety. Through the design of the adjustment mechanism, when the vehicle body descends and contacts the glass, a spring compresses a sliding component. This, via the transmission of connecting rod one, movable column, connecting rod two, connecting rod three, and connecting rod four, allows the spraying roller to automatically adapt to and adhere to the glass surface. This design not only simplifies the operation process but also improves the adhesion between the spraying roller and the glass surface, thereby ensuring that the coating is applied evenly and effectively to the glass.

[0004] When applying thermal insulation coating to the exterior walls due to their large width, a suspended platform is typically used to support the workers and spraying equipment. The workers then manually spray the coating. During this process, the suspended platform is easily affected by wind and may sway, which in turn affects the quality of the coating application, resulting in uneven coating and affecting the actual performance of the coating. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an automatic spraying device for heat insulation coating.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic spraying device for heat insulation coating, comprising: The suspended platform has controllable electric telescopic rods installed on the upper and lower parts of its inner walls on both sides. The telescopic end of the electric telescopic rod passes through the front of the suspended platform and extends outward. The end of the extended end is fixedly installed with a support roller, and multiple laser rangefinders are installed on the front of the suspended platform. A support spraying frame is fixedly installed at the top of the front of the support basket, and a transverse slider is slidably installed inside the support spraying frame. A mounting connector is fixedly installed at the top of the transverse slider, and a paint spraying gun is fixedly installed in the middle of the mounting connector. A paint supply pump is installed inside the support basket, and a three-way connecting pipe is fixedly installed at the inlet of the paint supply pump.

The paint extraction pipes are connected to a paint storage tank, and a paint supply hose is fixedly installed at the outlet of the paint supply pump. The paint supply hose is connected to a paint spray gun.

[0007] As a further improvement of this utility model: a limiting slide rod and a transmission threaded rod are installed inside the bearing spraying frame, and both the limiting slide rod and the transmission threaded rod pass through the transverse sliding block.

[0008] As a further improvement of this utility model: the limiting slide rod is slidably connected to the transverse slider, and the transmission threaded rod is threadedly connected to the transverse slider.

[0009] As a further improvement of this utility model: a micro servo motor and a counterweight are fixedly installed at both ends of the bearing spraying frame, and the micro servo motor is connected to one end of the transmission threaded rod through a coupling.

[0010] As a further improvement of this utility model: a protective mounting bracket is fixedly installed at the bottom of the paint supply pump, and a battery pack is fixedly installed inside the protective mounting bracket.

[0011] As a further improvement of this utility model: a main controller is fixedly installed on the inner wall of the front of the supporting basket, and connecting cantilever arms are fixedly installed on the top of the outer walls on both sides of the supporting basket.

[0012] As a further improvement of this utility model: a protective top cover is fixedly installed on the top of the paint storage box, and an installation cylinder is fixedly connected to the middle of the top of the protective top cover.

[0013] As a further improvement of this utility model: a positioning and mounting tube is fixedly connected to one end of the top of the protective cover, and a liquid level sensor is fixedly installed inside the positioning and mounting tube.

[0014] Compared with the prior art, the present invention provides an automatic spraying device for heat insulation coating, which has the following beneficial effects: 1. This automatic thermal insulation coating spraying device uses four laser rangefinders to monitor the distance between the suspended platform and the wall in real time. The main controller dynamically adjusts the extension length of the four corner electric telescopic rods to ensure that the front of the suspended platform is always parallel to the outer wall. This design can adapt to outer wall surfaces with different flatness, avoiding uneven spraying or equipment misalignment caused by the tilt of the suspended platform, thus improving construction quality. The bearing spraying frame has a built-in transmission threaded rod driven by a micro servo motor, which, together with the limit slide rod, guides the horizontal sliding block to move at a uniform speed, driving the spray gun to operate horizontally at a uniform speed. After a single spraying is completed, the suspended platform only needs to descend by one spraying width to repeat the action, achieving continuous, efficient, and uniform spraying, greatly reducing manual intervention and improving construction efficiency.

[0015] 2. This automatic heat insulation coating spraying device uses two symmetrical coating storage tanks to simultaneously extract coatings, avoiding equipment tilting caused by excessive load on one side; the counterweight balance block further maintains the stability of the center of gravity of the bearing spraying frame, ensuring smooth operation of the device during spraying and reducing the impact of shaking on spraying accuracy; the coating supply pump draws material from the dual storage tanks through a three-way connecting pipe, and the supply hose is connected to the spray gun, ensuring stable material supply; the storage tanks are equipped with protective top covers, injection pipes, and sealing structures to prevent impurities from contaminating the coating and ensure spraying effect.

The top of the horizontal sliding block 7 is fixedly installed with a mounting connection seat 8, and the middle of the mounting connection seat 8 is fixedly installed with a paint spray gun 9. The paint spray gun 9 is controlled by the main controller 21.

[0027] A protective mounting frame 16 is fixedly installed on the inner wall of the bottom of the supporting basket 1. A battery pack 22 is fixedly installed inside the protective mounting frame 16, and the battery pack 22 supplies power to the whole device. A paint supply pump 17 is fixedly installed at the top of the protective mounting frame 16. A three-way connecting pipe 18 is fixedly installed at the inlet of the paint supply pump 17. Paint extraction pipes 19 are fixedly installed at both ends of the three-way connecting pipe 18. A paint supply hose 20 is fixedly installed at the outlet of the paint supply pump 17.

[0030] Working principle: Refer to Figures 1 to 3 Assemble the device as shown in the figure. Before use, connect the two steel cables of the cable winding device to the connecting cantilever 2. Establish a wireless signal connection between the cable winding length monitor and the main controller 21. Establish a wireless signal connection between the drive motor and brake of the cable winding device and the main controller 21. Establish a wireless signal connection between the main controller 21 and the mobile terminal (the terminal held by the worker) for remote control by the worker. When the device is in operation, the cable winding device is fixedly installed on the roof, the supporting basket 1 moves from top to bottom, and the paint spray gun 9 sprays paint onto the exterior wall in sequence. When using this device, the main controller 21 first activates the four electric telescopic rods 13. The electric telescopic rods 13 extend, and the supporting rollers 14 contact the outer wall. The four laser rangefinders 15 simultaneously send data back to the main controller 21. Based on the feedback data, the main controller 21 adjusts the extension length of the four electric telescopic rods 13 so that the front of the supporting basket 1 is parallel to the wall. Then, the main controller 21 controls the paint supply pump 17 to start and turns on the paint spray gun 9. The paint spray gun 9 sprays the paint in the paint storage tank 23 in a fan shape. At the same time, the micro servo motor 10 starts, and through the transmission thread... Rod 6 drives the transverse slider 7 to move at a low and uniform speed, which in turn drives the paint spray gun 9 to move synchronously, spraying the paint evenly onto the exterior wall. When the transverse slider 7 moves from one end of the transmission threaded rod 6 to the other end, the paint spray gun 9, the micro servo motor 10, and the paint supply pump 17 are simultaneously shut down. The main controller 21 sends a descent command to the steel cable unwinding device, and the steel cable is unwound, causing the supporting basket 1 to move downwards by a distance equal to the paint spraying width. Then, the micro servo motor 10 reverses, and its structure starts synchronously, spraying the exterior wall again. The above operation is repeated to spray the entire exterior wall.
