[0002] A surface coating device for packaging steel strip production is used to uniformly spray a protective or decorative coating onto the surface of packaging steel strips. It typically consists of a paint supply system, a spray gun, a transmission mechanism, and a control system. The paint supply system stores and delivers the paint; the spray gun atomizes the paint and sprays it onto the steel strip; the transmission mechanism drives the steel strip to move at a constant speed to ensure uniform coating; and the control system precisely regulates various spraying parameters, thereby improving the rust resistance, wear resistance, and appearance quality of the steel strip.

[0003] The prior art discloses a surface treatment spraying device for cold-rolled stainless steel strip production, application number 202221461184.8, comprising a base plate, a support frame, and guide rollers. The support frame is symmetrically welded to the surface of the base plate, and the guide rollers are equidistantly rotatably arranged inside the support frame. A spraying frame is welded to the surface of the base plate, and a traction rod is slidably inserted into the surface of the spraying frame. The top end of the traction rod is fixedly connected to the traction frame, and the bottom end of the traction rod is fixedly connected to the spraying hood. A guide pipe is conductively connected to the upper surface of the spraying hood. A cleaning frame is welded to the surface of the base plate, and a cleaning cotton pad is adhered to the bottom of the cleaning frame. The stainless steel strip is directionally fed along the guide rollers of the support frame.

[0024] The spraying mechanism 2 includes an atomizing spraying unit and an auxiliary transmission unit. The atomizing spraying unit is movably connected to the inside of the supporting mechanism 1, and the auxiliary transmission unit is fixedly connected to the inside of the supporting mechanism 1.

[0025] The bearing mechanism 1 consists of a spray box 101, a drain valve 102, a pipe interface 103, a splash guard 104, and a transmission port 105. The drain valve 102 is fixedly connected to the surface of the spray box 101, the pipe interface 103 is fixedly connected to the surface of the spray box 101, the splash guard 104 is fixedly connected to the top of the spray box 101, and the transmission port 105 is opened on the left and right sides of the spray box 101, which serves as a bearing and can collect and recycle excess spray.

[0026] The atomizing spray unit consists of a first support frame 201, an annular frame 202, a guide pipe 203, a connecting pipe 204, and atomizing nozzles 205. The first support frame 201 is fixedly connected to the inside of the spray box 101, the annular frame 202 is fixedly connected to the top of the first support frame 201, the guide pipe 203 is fixedly connected to the surface of the annular frame 202, the connecting pipe 204 is fixedly connected between the pipe interface 103 and the guide pipe 203, and the atomizing nozzles 205 are fixedly connected to the inside of the annular frame 202, serving as the spraying process. The atomizing nozzles 205 are connected to the guide pipe 203, serving to conduct liquid material. The atomizing nozzles 205 are distributed on the inner side of the annular frame 202, facilitating the wrapping and spraying of the steel strip, enabling simultaneous spraying of the entire steel strip, and improving processing efficiency. The auxiliary transmission unit consists of a second support frame 211, a driven roller 212, a guide rail frame 213, and a lifting frame 21. 4. The system consists of a drive roller 215, a cylinder 216, a telescopic rod 217, and a drive motor 218. The second support frame 211 is fixedly connected to the left and right ends inside the spray box 101. The driven roller 212 is rotatably connected to the top of the second support frame 211. The guide rail frame 213 is fixedly connected to the top of the second support frame 211. The lifting frame 214 is movably connected to the surface of the guide rail frame 213.
