[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0018] Example: like Figure 1 - Figure 7 As shown, this embodiment proposes a coating spraying device for the inside of a cylinder 2, comprising a housing 1, a cylinder 2, a spraying assembly, a rotating assembly and a driving unit, wherein the rotating assembly comprises a turntable 3 arranged on the housing 1, and the cylinder 2 is arranged on the surface of the turntable 3, and the spraying assembly comprises a spraying head 4 arranged in the housing 1 and extending through the housing 1 and the turntable 3 to the inside of the cylinder 2, wherein as the spraying head 4 sprays, the driving unit drives the turntable 3 to rotate, so that the cylinder 2 rotates accordingly, thereby coating the inside of the cylinder 2; By placing the open end of the cylinder 2 that needs to be coated on the surface of the carrier plate 17, as the cylinder 2 squeezes the carrier plate 17, the spring 16 deforms, so that the cylinder 2 is inserted into the second circular groove 14, and abuts against the outer wall of the cylinder 2 through the baffle 15, so as to complete the fixation of the cylinder 2, and then the paint in the storage tank 5 is transferred to the spray head 4 through the suction pipe 6, so that the inner wall of the cylinder 2 is sprayed. While spraying, as the motor 18 drives the second gear 19 to rotate, the second gear 19 is meshed with the first gear 11, and then drives the first gear 11 to rotate, the moving column 13 slides in the second circular groove 14 along the length direction of the second circular groove 14, driving the turntable 3 to rotate, so that the cylinder 2 rotates accordingly, so that the spray head 4 can spray more evenly during coating. Evenly, by spraying a coating on the inner wall of the cylinder 2, the coating can effectively protect the inner wall of the cylinder 2 and reduce the deformation and damage of the cylinder 2 caused by wear and corrosion. The coating in the storage tank 5 is PTFE (polytetrafluoroethylene). PTFE has an extremely low friction coefficient, usually between 0.05 and 0.1, which greatly reduces the friction between the inner wall of the cylinder 2 and the piston, thereby reducing energy loss and improving engine efficiency. PTFE has stable chemical properties and good corrosion resistance to most chemicals. It can effectively protect the inner wall of the cylinder 2 from erosion by corrosive components in fuel and lubricating oil. By reducing the friction between the inner wall of the cylinder 2 and the piston, the PTFE coating can reduce the mechanical loss of the engine, thereby improving fuel economy and power output.

When the cylinder 2 is inserted into the second circular groove 14, the four baffles 15 can abut against the outer wall of the cylinder 2, so as to limit the cylinder 2 and improve the stability of the cylinder 2 during the rotation process. A plurality of springs 16 are arranged in the second circular groove 14, and a bearing plate 17 is installed on the upper surface of the spring 16. When the cylinder 2 is inserted into the second circular groove 14, the cylinder 2 falls on the surface of the bearing plate 17 and squeezes the bearing plate 17. After being squeezed, the spring 16 is deformed and elastically reacts to the bearing plate 17, so that the bearing plate 17 can generate a certain top force on the cylinder 2, so as to facilitate the subsequent staff to take the cylinder 2.
