Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, and more precisely to a double-sided spraying device. Background Art

[0002] In modern industrial production, coating technology is increasingly used. Whether it is to improve the corrosion resistance and wear resistance of products or to enhance the aesthetics of products, spraying is a key link.

[0003] However, current spray coating systems on the market present numerous practical challenges. For one thing, many can only coat one side of a workpiece. For workpieces requiring double-sided coating, two separate spraying operations are often required, or the workpiece must be manually flipped over to achieve double-sided coating. This not only consumes significant time and labor costs, but also, due to the time between spraying cycles and the uncertainty of manual operation, can easily lead to uneven coating, compromising product quality.

[0004] On the other hand, some equipment capable of double-sided spraying usually uses two sets of independent lateral and longitudinal displacement mechanisms to control the two nozzles respectively. This design makes the equipment structure complex, costly, and also brings great difficulties in operation and maintenance. Utility Model Content

The workbench is also provided with a workpiece carrier and a feeding mechanism for driving the workpiece carrier to move.

[0008] Furthermore, the workbench is provided with a first transverse slide groove and a second transverse slide groove; the transverse displacement mechanism includes a transverse screw rod arranged in the first transverse slide groove and a transverse displacement motor driving the transverse screw rod to rotate, the mounting frame is threadedly connected to the transverse screw rod, a transverse guide rod is fixedly connected in the second transverse slide groove, and the mounting frame is slidably sleeved on the transverse guide rod.
