Description

Technical Field

[0001] The invention belongs to the technical field of spraying equipment, and in particular relates to a uniform and fine spraying equipment for building wall paint and a spraying method thereof. Background Art

[0002] Wall paint spraying equipment is a professional device that uses mechanical devices to spray or apply paint. It is widely used in architectural decoration, industrial manufacturing and other fields. This equipment is easy to operate and is suitable for spraying operations on various walls and ceilings, which can greatly improve construction efficiency.

[0003] For example, the national patent publication number CN116427666A describes a high-rise building wall facade spraying device, which aims to solve the problem of unstable quality control of wall facade painting in the prior art. It is slidably installed on the handrail of the hanging basket, and a counterweight equipment box is provided toward the inside of the hanging basket, including a rod-shaped frame, on which a vertical painting frame is slidably installed, and on which a slider driven by a screw lifting mechanism is provided. The slider is provided with at least three claw-shaped pressing-type painting mechanisms, and a feeding device is provided below the pressing-type painting mechanism. The advantages are: it is suitable for situations where fine-tuning is required, the equipment is simple and the working steps are complex, and at the same time, the complex working steps can be extended to a variety of usage methods, and it should have a wide range of uses. However, the conventional device still has the following problems when used: Due to the high-altitude operation, the stability of the above-mentioned device is relatively low. Especially during the mechanical movement of the sliding device, the inertia of movement and the offset of the center of gravity of the device will cause the hanging basket to swing slightly. At this time, the spraying direction and the spraying axis of the spraying mechanism will gradually radiate and produce a large offset, which seriously affects the uniform and fine spraying of the spraying equipment. This swinging process can only rely on the rope to drive itself to gradually stabilize, and the stabilization efficiency is slow, which affects the spraying efficiency and quality.

At this time, the present invention The swing force is transmitted to the wall by the pressure of the pressing roller 9, so that the swing force in random directions is fixedly transmitted to the lateral movement, and the fixed vertical gravity of the four points of the hanger 1 by the crane simultaneously offsets the inertia of part of the lateral movement, so that the present invention can be fast and stable, ensuring the stability of the spraying equipment, thereby improving the spraying efficiency and quality, and achieving uniform and detailed spraying. In the present invention, the adjustment springs 19 on the two rotating rollers 7 are installed in a mirror direction.

By installing the tension spring 12 and the telescopic adjustment rod 11, the present invention has a certain Z-axis elasticity, achieving fast and stable results. In the present invention, the paint in the liquid carrier 35 is transmitted to the atomizing operation nozzle 30 through the output pipe 32 for spraying. The staff controls the rotation of the electronically controlled bearing 25 through the central console 34, which can realize the adjustment of horizontal and vertical uniform and detailed spraying, with a more flexible operation mode and an adjustable operating range, which improves the applicability of the present invention. In the present invention, when the hanger 1 falls to the ground, the connecting base plate 4 rotates below the supporting base plate 2. At this time, the rotating roller 7 will be engaged in the stable card slot 21, achieving a stable placement effect and avoiding shaking.
