Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying for machine tool processing, in particular to a paint spraying device for processing a bed of an engraving machine. Background Art

[0002] When producing engraving machines, the body needs to be treated with anti-rust paint.

[0003] A Chinese patent application, publication number CN214811931U, discloses a paint spraying device for machining a CNC engraving machine bed with an angle adjustment function. The device comprises a support block, a paint spraying device, a machine housing, a movable door, an activated carbon box, and a movable cover. The paint spraying device is fixed to one side of the lower end of the machine housing. Connecting pipes are welded to the middle of the upper ends of both sides of the machine housing, and the connecting pipes are at right angles. The lower ends of the connecting pipes are connected and mounted on the paint spraying device. A plastic bellows is connected and mounted on the end of the connecting pipe facing away from the paint spraying device. A nozzle is connected and mounted on the end of the plastic bellows facing away from the connecting pipe. A through hole is formed in the middle of the upper end of the machine housing, and a connecting groove is fixed to the upper end of the machine housing outside the through hole. A sealing ring is fixed inside the movable cover, and the movable cover is threadedly mounted on the upper end of the connecting groove. This utility model has the advantage of facilitating the angle adjustment of the nozzle of the paint spraying device.

[0004] However, the device still has the following disadvantages: the device uses a nozzle to spray paint, but the position of the nozzle and the workpiece cannot be adjusted, and the painting position cannot be changed, resulting in a small painting range and the need to adjust the position of the workpiece later, which reduces the processing efficiency. To solve this problem, we proposed a painting device for engraving machine bed processing. Utility Model Content
