Description

Technical Field

[0001] The utility model relates to the technical field of bicycle production, in particular to a paint spraying device for bicycle frame production. Background Art

[0002] A bicycle, also known as a cycle or bike, is usually a small two-wheeled land vehicle. People ride the bicycle and use the pedals as power. It is a green and environmentally friendly means of transportation and can be used as an environmentally friendly means of transportation for commuting and traveling. More and more people use bicycles as fitness equipment for cycling exercises and bicycle travel. Cycling itself is also a sport. The bicycle frame is the skeleton of a bicycle and is the main load-bearing structure.

[0003] Nowadays, bicycles need not only good performance but also beautiful appearance. Therefore, bicycle frames need to be sprayed with a layer of paint during the production process. This not only improves the appearance but also delays rusting of the bicycle frames. However, at present, bicycle frames are often sprayed with a handheld spray nozzle. This method of spraying paint easily leads to a decrease in the uniformity of the paint, thereby reducing the aesthetics of the bicycle. In addition, paint has certain hazards to the human body. Workers who spray paint for a long time are prone to physical damage. Utility Model Content
