Compact Spray Paint Machine

Model: SL-TSRB

Bring automatic spraying, clean-air supply, overspray capture, and panel conveying into one compact finishing cell. Four height-adjustable spray guns move with the reciprocating mechanism to cover flat workpieces, while positive-pressure filtered air and a circulating water curtain manage the spray environment around the coating zone.

Application Materials:

  • Fiber cement board, Magnesium oxide board, Calcium silicate board
  • Wood, MDF, Particleboard, Plywood, PVC, PET
  • Glass, Metal, Ceramics, Plastic, Special material, etc.

Application Coatings:

  • PU, PE, NC, AC, UV, Ink, Water-based paint
  • Fluorocarbon paint, Glue, Special paint, etc.

Compact Spray Paint Machine for Flexible Panel Finishing

The compact spray paint machine combines reciprocating coating application, filtered air supply, overspray capture, and workpiece conveying inside one enclosed finishing cell. Four height-adjustable spray guns move above the panel path while product detection controls gun activation as each workpiece enters the spray zone. You can process wood-based panels, PVC, PET, glass, metal, ceramics, calcium silicate board, and other compatible flat materials with a range of decorative or functional coatings.

Keep the Spray Pattern Moving With the Workpiece

The reciprocating mechanism carries the spray guns across the panel instead of relying on a fixed spray position. Gun height and operating settings can be adjusted around the workpiece and coating process, while the diaphragm pump maintains paint delivery to the spraying section.

The standard spray setup brings several functions together:

  • Four height-adjustable IWATA air spray guns
  • Reciprocating motion across the workpiece path
  • Automatic gun activation based on product detection
  • Continuous paint delivery through a diaphragm pump
  • Automatic lubrication for the reciprocating guide system

GRACO and KREMLIN spray guns are also available when your coating specification calls for a different gun configuration.

Control the Air Around the Coating Zone

A clean spray environment starts above the workpiece. Filtered positive-pressure air enters through the upper section of the booth, helping limit airborne contamination around the wet coating.

Overspray moves toward the circulating water curtain behind the spraying area, where paint particles are captured by the water flow. The rear stainless-steel filtration section provides another treatment stage before the extracted air reaches the external exhaust connection. Spray application and mist control therefore remain concentrated around the same enclosed work area.

Keep Operation Close to the Spray Cell

The cantilevered HMI sits beside the machine and can move with the operator position. Product-detection signals feed the PLC, which coordinates spraying and gun activation as workpieces pass through the booth.

You can adjust the spray configuration around different coatings while retaining the same compact machine layout. PU, PE, NC, AC, UV, water-based paint, fluorocarbon coatings, ink, glue, and other compatible materials are listed for the equipment.

Continue From Spraying Into the Finishing Line

Once coated, panels can move directly toward the required drying or curing stage. The machine can sit within a broader spray paint machine setup or connect with a UV spray painting line when compatible UV coatings are used.

Where the coating requires hot air, infrared, UV, or another drying method, the appropriate section can be selected from the paint drying oven range. This keeps spraying, overspray management, and downstream drying connected within the same production route.

Excellent Adaptability for Rolls and Sheets

This compact spray paint machine features a precision reciprocating spraying mechanism, offering excellent adaptability for various coil and sheet workpieces. Its stable conveying system and controllable spraying motion prevent workpiece deformation while ensuring full coating coverage. Compared to roller coating or curtain coating methods, this machine achieves more uniform coating and penetration on edges and other hard-to-reach recesses.

Balancing Efficiency and Convenience

The compact spray paint machine integrates high-efficiency mass production with flexible and convenient operation. Equipped with a variable frequency drive, its production speed is adjustable according to workpiece width, coating thickness and drying time requirements, enabling stable large-scale manufacturing. The system features simplified parameter configuration, with easy operation, routine cleaning and maintenance.

Saving Space and Costs

Compared to our heavy-duty dual-arm reciprocating spray painting machine, this compact spray paint machine conserves valuable production space and lowers equipment investment costs. At the same time, it retains important functions, such as a positive-pressure air system and paint recovery, and remains compatible with various decorative and functional coatings, meeting high-quality finishing requirements for diverse workpiece materials.

Standard Characteristics

Reciprocating Spraying System

The compact spray paint machine features a top-mounted reciprocating spray mechanism and four height-adjustable Japanese IWATA high-pressure air spray guns to ensure uniform spraying. A high-flow diaphragm pump delivers a stable, continuous supply of paint. An integrated automatic lubrication system regularly injects fresh lubricating oil into the guide rails, ensuring consistent and smooth operation.

Cyclic Water Curtain System

The spray booth is equipped with a high-efficiency circulating water curtain system. Combined with the positive-pressure air system at the top of the machine, excess overspray paint mist is captured and absorbed by the circulating water flow, separating the paint particles from the exhaust gas. The system maintains a clean, pollution-free internal environment, ensuring a high-quality spray effect while reducing smell.

Paint Filtration System

The top of the spray painting machine is equipped with a high-efficiency air filter, and positive-pressure airflow passes through the filter to maintain a clean, dust-free environment inside the paint chamber. A two-stage, all-stainless-steel rear filtration system on the back of the machine purifies paint mist before it is emitted. A high-power fan connected to the outlet duct draws the paint mist away.

Automatic PLC Control HMI

The cantilevered, movable user interface is bilingual (Chinese and English), and custom languages can be selected upon request. The color touchscreen allows for precise parameter adjustment, and the PLC system automatically controls the spraying operation and spray gun activation based on product detection signals, ensuring stable, accurate, and efficient automatic spraying.
