DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 4 As shown, the utility model provides a stainless steel elbow pipe finishing device, including a frame 1, both ends of the bottom wall of the frame 1 are fixedly connected with a support seat 2 for placing the elbow pipe fitting 3, one end of the top of the frame 1 is rotatably connected with a screw rod 5, and the other end of the top of the frame 1 is fixedly connected with a fixed rod 6 arranged parallel to the screw rod 5, and a motor 4 is fixedly installed on the outside of the frame 1, and the output shaft of the motor 4 is fixedly connected to the screw rod 5. A movable seat 7 is threadedly connected to the screw rod 5, and the end of the movable seat 7 away from the screw rod 5 is slidably connected to the fixed rod 6, and a paint spraying mechanism 8 is provided on the inner side of the movable seat 7 for cooperating with the translation of the movable seat 7 to spray paint on the outside of the elbow pipe fitting 3.

[0020] By starting the motor 4 to rotate the screw rod 5, the movable seat 7 and the screw rod 5 rotate relative to each other, and the movable seat 7 translates along the axial direction of the screw rod 5, so that the paint spraying mechanism 8 translates with the movable seat 7 and sprays paint on the outside of the elbow pipe fitting 3, thereby realizing the painting work on the elbow pipe fitting 3.

[0021] Among them, the paint spraying mechanism 8 includes a slider 81, which is slidably connected to the inner side of the movable seat 7, and a return spring 82 is welded to one end of the slider 81. The end of the return spring 82 away from the slider 81 is welded to the inner wall of the movable seat 7, and the bottom of the slider 81 is rotatably connected to a rotating rod 83. The bottom end of the rotating rod 83 is fixedly connected to a paint spraying part 84 mounted on the outside of the elbow pipe fitting 3, and a guide mechanism 9 is provided on the inner side of the frame body 1 to guide the rotating rod 83 to translate along the pipeline of the elbow pipe fitting 3.

[0022] Through the translation of the movable seat 7, the rotating rod 83 will translate along the pipeline of the elbow pipe fitting 3 under the guidance of the guide mechanism 9, which enables the paint spraying part 84 arranged on the outside of the elbow pipe fitting 3 to translate along the pipeline of the elbow pipe fitting 3 to spray paint, thereby realizing rapid painting of the elbow pipe fitting 3 and greatly improving the painting effect.

[0023] The guide mechanism 9 includes a mounting plate 91, which is fixedly connected to the inner side of the frame 1. A through guide groove 92 is provided on the mounting plate 91. The rotating rod 83 is slidably connected to the inner wall of the guide groove 92. The shape of the guide groove 92 matches the shape of the elbow pipe 3. When the movable seat 7 is translated, the rotating rod 83 slides along the inner wall of the guide groove 92, and the return spring 82 can make the rotating rod 83 elastically contact with the inner wall of the guide groove 92, thereby avoiding the problem of the rotating rod 83 being stuck in the guide groove 92.

[0024] Among them, the paint spraying part 84 includes an annular sleeve 841, which is sleeved on the outside of the elbow pipe fitting 3. The inner wall of the annular sleeve 841 is fixedly connected with an annular tube 842, and a plurality of paint spraying heads 843 are fixedly connected to the annular tube 842. The plurality of paint spraying heads 843 are distributed at equal angles around the annular tube 842. A paint guide hose 844 is fixedly connected to the outside of the annular tube 842. The outlet end of the paint guide hose 844 is connected to the inside of the annular tube 842, and the inlet end of the paint guide hose 844 is externally connected to a corresponding paint supply device.

[0025] Working principle: By starting the motor 4 to rotate the screw rod 5, the movable seat 7 and the screw rod 5 rotate relative to each other, which makes the movable seat 7 translate along the axial direction of the screw rod 5, so that the rotating rod 83 slides along the inner wall of the guide groove 92, thereby making the annular tube 842 translate along the pipeline of the elbow pipe fitting 3, and at the same time, the paint spraying head 843 sprays paint on the outer wall of the elbow pipe fitting 3, thereby achieving uniform painting of the outer wall of the elbow pipe fitting 3, effectively solving the problem of inconvenience in painting the elbow pipe fitting 3 in the prior art.
