[0002] In the field of color steel plate production, high-quality spraying plays a crucial role. It not only significantly improves the appearance quality of color steel plates, making their surfaces smoother and colors more vibrant, but also has a decisive effect on enhancing the corrosion resistance of color steel plates. The degree of precision in spraying directly affects the durability and service life of color steel plates. Therefore, adopting advanced spraying technology and strict quality control processes to ensure that each layer of paint uniformly and stably covers the surface of the steel plate is the key to producing high-quality color steel plates. In addition, the choice of spraying materials is also crucial. High-quality paint can provide better protection against environmental erosion, ensuring that color steel plates maintain their aesthetic and functional properties in various harsh conditions. Therefore, color steel plate production enterprises must pay attention to every aspect of the spraying process, from technical training to equipment maintenance, from material selection to process flow, to ensure the excellent quality of the final product.

[0033] Working principle: Color steel plate is placed on the steel plate transmission belt 318, and the device is started by controlling the panel 319. The steel plate transmission belt 318 starts to run, and the color steel plate is transported into the spraying protective box 311 from one of the access openings 317. At the same time, the spray head adjusting part 4 adjusts the position of the spray head 4119 as needed to spray the color steel plate. The excess paint generated during the spraying process falls into the recycling hopper 312 through the strip-shaped opening 3111, and is discharged through the discharge pipe 313 for recycling.

[0034] When the steel plate transmission belt 318 starts, it circulates in the spraying protective box 311. The color steel plate is placed on it, and the friction is increased by the grooves on the strip-shaped support block 3112 to prevent the color steel plate from sliding. The color steel plate moves in the spraying protective box 311 with the movement of the steel plate transmission belt 318, and is sprayed in turn by the spray head 4119. The recycling hopper 312 is located at the bottom of the spraying protective box 311, and receives the excess paint falling from the strip-shaped opening 3111 on the steel plate transmission belt 318 through the communication with the spraying protective box 311. The discharge pipe 313 is in communication with the recycling hopper 312, discharges the recycled paint, and can be connected to a paint recycling treatment system or a storage device. The on-off valve 314 is used to control the on-off of the discharge pipe 313, facilitating the discharge operation of the paint when needed.

[0035] When the motor 417 starts, the output end drives the rotating slide rod 418 to rotate. The rotating slide rod 418 is kept in a stable rotating state by the positioning sleeve 419, which is fixed on the outer wall of the limiting block two 413 to provide support and positioning for the rotating slide rod 418. The threaded screw rod 41111 is rotated by the rotating slide rod 418. One end is connected with the rotating slide rod 418, and the other end is connected with the limiting block one 411 through the rotating rod and the rotating sleeve. The rotation of the threaded screw rod 41111 makes the adjusting slide block 414 move on its outer wall. The threaded sleeves 415 on both sides of the adjusting slide block 414 are screwed with the threaded screw rod 41111 to ensure that the adjusting slide block 414 can move along the axial direction of the threaded screw rod 41111. The adjusting slide block 414: the fixed rod 4111 at the bottom is slidingly connected with the moving slide groove 316 to ensure the stability of the adjusting slide block 414 during movement. With the movement of the adjusting slide block 414, the fixed rod 4111 slides in the moving slide groove 316, thereby changing the position of the spray head 4119 in the horizontal direction.

[0036] The telescopic end of the air cylinder 4117 is fixedly connected with the storage tank 4118, and the height of the storage tank 4118 can be adjusted through the telescopic action. The storage tank 4118 is slidably connected with the positioning hole on the fixed plate 4112 through the slide rod 4115, so that the movement of the storage tank 4118 in the vertical direction is stable. When the air cylinder 4117 is telescoped, the storage tank 4118 is driven to move up and down, so that the position of the spray head 4119 in the vertical direction is adjusted. The storage tank 4118: stores paint inside, and sprays the paint out through the spray head 4119 at the bottom, so as to perform the spray coating work on the color steel plate. The communicating water pipe 4114 communicates with the storage tank 4118, and provides paint supply for the storage tank 4118. The water pipe fixing sleeve 4113 is used for fixing the communicating water pipe 4114, so as to ensure the stability of the communicating water pipe 4114 during the work.
