[0027] The first motor 2 is mounted on the frame 1, the storage hopper 3 is mounted on the frame 1 through the base 5, the output end of the first motor 2 extends into the storage hopper 3, the feeding end of the feeding structure is located in the storage hopper 3 and is connected to the output end of the first motor, the discharging end of the feeding structure is directly opposite to the brush roller 15, the brush roller 15 is rotatably mounted on the moving head fixture 4 through the axle 14, the driving mechanism is fixed on the moving head fixture 4, the end of the axle 14 is mounted with a large gear 16, and the driving mechanism is in transmission connection with the large gear 16. The setting of the base 5 can prevent the paint from leaking and connect and seal the storage hopper and the first motor.

[0028] The feeding structure comprises a first feeding component and a second feeding component, and the first feeding component is connected with the second feeding component.

[0029] The first feeding assembly includes a feeding shaft 6, a spiral shaft 7 and a metal tube 8. The feeding shaft 6 is connected to the output end of the first motor 2. The spiral shaft 7 is arranged on the outer wall of the feeding shaft 6. The spiral shaft 7 has a tapered spiral shaft body upward, and the reduced spiral shaft body has a certain length. The metal tube 8 is sleeved on the outside of the spiral shaft 7 as the shape of the spiral shaft changes, and there is a gap between the metal tube 8 and the spiral shaft 7. Driven by the first motor 2, the feeding shaft drives the spiral shaft to rotate, thereby transporting the material from the gap between the metal tube 8 and the spiral shaft 7 to the second feeding assembly.

[0030] The second feeding assembly includes a silicone tube 9 and a feeding body 10. One end of the silicone tube 9 is connected to the metal tube 8, and the other end is connected to the feeding body 10. A shaftless spiral blade 11 is arranged inside the silicone tube 9. The feeding port of the feeding body 10 faces the coating mechanism. The upper end of the silicone tube 9 is connected to a three-way pipe, and the three-way pipe is connected to the three pipe heads of the feeding body 10 through a hose. The feeding body 10 is like two hands with five fingers together and the knuckles bent together. Two inner feeding plates are inside and two outer feeding plates are outside, forming a coating channel body with an inner cavity, one inside and one outside, which is the feeding body.

[0031] The driving mechanism includes a second motor 12 and a pinion 13 . The second motor 12 is mounted on the moving head fixture 4 , and an output end of the second motor 12 is connected to the pinion 13 . The pinion 13 is meshed with a large gear 16 .

[0032] To further optimize the technical solution, front guard plates 17 are provided on both sides of the brush roller 15 , and a tube body is connected to the rear end of the front guard plate 51 . A thin metal shaft is provided through the tube body, and the thin metal shaft is fixedly mounted on the moving head assembly 4 .

[0033] To further optimize the technical solution, a closed lid 18 is fastened to the upper opening of the storage hopper 3 , and a material injection port is provided on the lid 18 , through which the coating liquid can be injected into the interior of the storage hopper 3 .

[0034] To further optimize the technical solution, a track holder 19 is installed on the side of the moving head fixture 4 away from the front guard plate 17.

[0035] The principle of the present invention is to use the thick and bent nylon hair of the brush roller to store the paint. The brush roller will generate a strong centrifugal force during high-speed rotation. This force can "throw", "hit" and "stack" the paint on the wall, thereby replacing the heavy manual physical painting work. The principle is that when the paint slurry enters the brush body, since the hair is bent, it can first lock the slurry. Secondly, under the action of centrifugation, the thrown material will move in a curved arrangement. Therefore, when the brush roller throws the material, the paint will be subdivided into 0.1-0.4 particles. Spraying 0.1-0.4 granular paint on the wall is the best wall aggregation effect. Such machine operation not only has a fast operation speed, uniform paint, and good effect, but also has minimal pollution, is light and easy to use. The present invention can reduce the waste and pollution of paint through the structural setting of the brush roller, and at the same time improve the bonding strength between the paint and the wall surface, making the wall coating more uniform and firm. The feeding structure can ensure the stable supply and uniform delivery of the paint, further improving the stability and reliability of the construction, and aims to improve the operation efficiency, ensure the construction quality, reduce the labor intensity of workers, reduce safety risks, and reduce the pollution burden on the environment through mechanization and automation. The introduction of this innovative technology can promote technological innovation in the construction industry and contribute to the realization of green, efficient and safe modern construction methods.

[0036] Small aeration during operation: The principle of short-distance centrifugal parabolic coating is similar to that of air pressure spraying, but there are significant differences. Due to the short distance of the coating, under the action of the isolation plate, the parabolic force can prevent the coating from generating a large chaotic flow in the air, thereby ensuring that there is almost no aeration during the coating process, greatly reducing the occurrence of polluting operations.

[0037] The paint is firmly bonded to the wall: The particle diameter of the centrifugal parabolic paint is between 0.1 and 0.4, and it will not cause bubble isolation when it is thrown on the wall, so the close contact rate between the paint and the wall is extremely high. In addition, the paint slurry can be embedded in the micro grooves of the wall, creating excellent conditions for material aggregation.

[0038] Energy saving: The paint particles are small and viscous, and the shaftless screw pusher requires very little power. The principle is not to rely on the power to achieve the paint work of strong material pushing, but to complete its functional mission by simply delivering the paint to the parabolic wheel. The actual forceful spraying operation is mainly concentrated on the parabolic wheel at the mouth end, and the parabolic wheel only needs a relatively small power motor to drive it.

[0039] Small size: The function formed by this structure is very suitable for various indoor decoration and other spraying operations, and can be combined and coordinated with many mechanical devices to form an integrated device. The machine is exquisitely designed and can be operated by one person.

[0040] The operation process of the present invention is as follows: the paint liquid is injected into the storage hopper 3, and the first motor 2 drives the feeding shaft 6 to rotate. The spiral shaft 7 of the feeding shaft 6 rotates the paint liquid into the shaftless spiral blade 11, and the shaftless spiral blade 11 pushes the paint into the feeding body 10. The paint passes through the inner feeding plate to fill a line of the material mouth on the brush roller 15, and the paint is evenly provided to the brush roller 15. The paint is pushed into the inside of the bent hairs of the brush roller 15. Because of the high-speed rotation of the brush roller 15 and the centrifugal force generated, the paint stored in the internal of the bent hairs is hit, pressed, and accumulated on the wall along the gaps between the thousands of threads with paint particles of about 0.1-0.4, thereby forming the new wall surface, new practical effects, new atmosphere and style, and a brand-new feeling experience that people expect.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
