Description

Technical Field

[0001] The utility model belongs to the technical field of plastic part coating, and in particular relates to a plastic part coating device. Background Art

[0002] Plastic parts need to be sprayed after production. In this process, a coating device is needed to apply paint to the surface of the plastic parts.

[0003] Existing coating devices generally include a conveyor belt and multiple clamping mechanisms installed on the conveyor belt. Multiple plastic parts are clamped on the conveyor belt in sequence by the clamping mechanisms. Since the clamping mechanisms do not have the function of rotating the plastic parts, in order to improve the uniformity of coating of the plastic parts, multiple paint spraying mechanisms for spraying the plastic parts at multiple angles are generally arranged on the conveyor belt, or multiple paint spraying mechanisms are added in multiple directions at a workstation. When the plastic parts pass through multiple workstations, the paint spraying has layers on the plastic parts due to the intervals in the paint spraying time. In addition, when multi-directional spraying is performed at a workstation, the paint spraying thickness in some areas will increase, resulting in uneven spraying thickness of the plastic parts, affecting the coating effect of the plastic parts.
