Description

Technical Field

[0001] This utility model relates to the field of surface coating technology, specifically to a spraying device for surface treatment of castings. Background Technology

[0002] In the surface treatment process of castings, spraying is a key process for corrosion prevention, wear resistance, and decoration, which directly affects the service life and appearance quality of the castings. Traditional spraying methods mostly use manual hand-held spray guns or fixed spraying equipment, which have problems such as uneven coating, low spraying efficiency, and high labor intensity. Especially for castings with complex structures, manual spraying is difficult to guarantee the coverage of corners, grooves, and other parts, which can easily lead to uneven coating thickness and affect product performance. Traditional equipment lacks an effective waste recycling system, and excessive paint mist and particulate matter generated during the spraying process can easily cause environmental pollution and increase subsequent cleaning costs.

[0003] While automated spraying equipment on the market can partially replace manual labor, it still suffers from drawbacks such as poor adaptability and difficulty in changing models. For example, some equipment uses fixed clamps, which are difficult to adapt to iron parts of different sizes and shapes, resulting in insufficient production flexibility. Rotary spraying mechanisms often rely on complex transmission systems, which have high maintenance costs and are easily affected by wear. Existing waste collection systems for spraying devices generally use single-stage filtration, which does not completely separate paint mist and metal particles, easily clogging pipes or reducing recycling efficiency. Therefore, a spraying device for surface treatment of castings is proposed to address the above issues. Utility Model Content

Combined with a multi-axis adjustable spray gun array, it ensures uniform coating coverage. It is suitable for difficult-to-spray areas such as corners and grooves of complex castings, reducing coating thickness deviation. The sliding rail spray carriage supports simultaneous operation of multiple spray guns, greatly improving the consistency of mass production and reducing rework rate.

[0014] This utility model, through the structural design of the material collection box, uses heated rollers to pre-separate metal debris and filters to intercept paint mist particles. Combined with negative pressure suction, the waste is collected and recycled into the collection box, avoiding the clogging that is common in traditional single-stage filtration. It separates and reuses recyclable paint, reducing material waste. The standardized setting of the exhaust pipe interface facilitates connection to the factory's environmental protection system, controls dust emissions during the spraying process, and reduces cleaning and maintenance costs.
