Description

Technical Field

[0001] This utility model belongs to the technical field of automotive painting equipment, specifically, it relates to a color-changing valve structure and a robotic atomizer. Background Technology

[0002] In the automotive manufacturing industry, the painting process is a crucial factor determining the appearance quality and durability of a vehicle. With the increasing demand for personalized and diverse colors in the automotive market, automotive painting production lines need to frequently change paint colors. Traditional color-changing methods typically employ multiple independent painting systems, each corresponding to a different color. This approach suffers from problems such as large equipment footprint, high costs, long color-changing times, and significant paint waste.

[0003] Application CN216182397U discloses a color-changing structure for an anti-overflow needle valve, including a valve needle and a valve sleeve. The valve sleeve has a flow channel, and the needle valve is cylindrical. The valve sleeve has a needle channel, and the valve needle is slidably disposed within the needle channel of the valve sleeve. The flow channel is connected to the needle channel, and the interface between the flow channel and the needle channel is located at the opening of the needle channel. This invention has the following advantages: by reducing the contact area between the valve needle and the plastic and reducing the contact time between the valve needle and the molten plastic, wear during the valve needle's movement is reduced, and the discharge speed is not decreased.

[0004] However, the aforementioned patent still has the following problems: When atomizing the paint, the internal structure of the color-changing valve is complex, and some pigment is easily retained in the flow channels and needle channels. During color-changing operations, the new pigment will inevitably mix with the residual pigment. This mixing leads to impure colors, resulting in quality problems such as color differences and spots, seriously affecting the exterior painting effect of the car, preventing the car from meeting the expected color standards, reducing the product's market competitiveness, and causing numerous connection points between the multiple sets of paint pigment tubes and the color-changing valve, making it difficult to effectively guarantee sealing performance.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content
