Reciprocating Spray Painting Machine

Model SL-TSWP

The reciprocating spraying machine is an automatic spraying equipment that can be used for mass painting.
It is suitable for manufacturers who require large-scale one-time spraying of the surface and four edges of products. Its compatibility allows it to match various coatings, such as UV paint, PU paint, water-based paint, metallic paint, primer and topcoat, etc. Even for products of different sizes, shapes, and materials, it can handle them with ease.
Integrated with a spacious paint booth, this machine is equipped with eight spray guns on two horizontal axes, running in the same or opposite direction for spraying. It has a complete positive pressure air system, automatic cleaning and paint recycling functions.
In practical applications, it is usually connected to dust cleaners, drying ovens, and sanding machines to achieve more efficient and labor-saving goals.

Advantages

Mass production

With a daily output of 1200-1800m2, the spray painting machine has excellent performance in mass production and enables significant improvement in your productivity.

Fine spray effect

The advanced automatic spraying system delivers outstanding spraying effects on the surface and sides of products, ensuring customer satisfaction.

High compatibility

Suitable to almost all panel products spraying surface and four sides, no matter what material, shape, or coating. Besides, the spraying machine can be customized for special needs.

Easy to operate

Automatic scanning, generating data, spraying, recycling the coating, and self-cleaning, the spraying machine simplifies manual operation and enhances user-friendliness.

Saving cost

Automation can significantly lower labor costs, as the machine replaces expensive painters. Moreover, an advanced spraying system can reduce paint waste and improve paint utilization to 80-95% ( depending on coating properties ).

Environment-friendly

Automated painting reduces harmful gases breathed in by humans and lowers the risk of occupational diseases. The specialized device can centrally filter and treat the paint mist in the air.

Standard Characteristics

GRACO air mix spray gun

Eight adjustable GRACO middle-pressure air mix spray gun can achieve uniform atomization and gentle spray, improve the paint transmission efficiency, and reduce the paint mist rebound.

GRACO bellows pump

GRACO Merkur bellows plunger pump has 24:1 pump pressure ratio and 9L flow, can quickly switch and recover, easy to rinse and make color change, less pulse achieve even spraying effect.

Straight quiet guide rail

Two spray axes at two ends reciprocate interactively, spraying fully the moving products evenly, its HIWIN quiet straight guide rail with automatic lubricating device ensures fast and smooth action.

Bonner light curtain

High-resolution and accuracy grating U.S. Bonner light curtain with solenoid valves, automatically detects the products, controls the spray range and the switch of the spray guns.

Servo motors

The two spray axes are driven by servo motors independently, controlled by PLC ensuring accurate spray motion and precise speed adjustment.

PE belt conveyor

The PE belt has high tensile strength, good winding, oil resistance, and easy cleaning, with the automatic rectification device and internal scraper that delivers steady keep clean.

Clean trolley

At the exit of the spray booth, the automatic belt clean trolley scratched redundant paint for recycling, then wash the running belt in two stages constantly to ensure it is clean and dry during work.

Air pressure system

The big fan and filter supply the large fresh air from the top of the spray booth, creating a pressured airflow space to reduce paint mist and bring down to the back multiple filter exhausts.

FAQs

1. How does reciprocating spray painting machine work?

The mechanical structure of this machine mainly consists of an automatic spraying system, a spraying booth, a conveying system, a liquid coating recycling and cleaning system, and a paint mist recycling system.

Substrates are transported at a uniform speed through a conveying system. Before entering the spraying booth, the detection light curtain will transmit the signal to the spraying control system. When substrates enter the spraying booth, two gun racks loaded with several spray guns will move back and forth at a constant speed. At the same time, the coating injected into the spray gun through the pump will be evenly sprayed onto the surface and four sides of the substrates.

After spraying, the substrates will enter the subsequent drying oven, and the excess paint remaining on the conveyor belt will be collected and cleaned centrally. The paint mist evaporated in the air will also be recovered and filtered by a specialized device.
2. What industries use spray painting machine?

Spray painting machines are widely used across industries. It is common in wood furniture, cabinets, doors, bathrooms, floors, glass, marble, fiber cement walls, stainless steel, and other fields. In recent years, its applications have expanded to more industries such as medical devices, sewage treatment, acoustical materials, transportation, and auto parts.
3. What is the history of reciprocating spray painting machine?

The reciprocating spraying machine has its roots in the early days of woodworking. Its development can be traced back to the 19th century, with early attempts to create a machine capable of spraying wood evenly and efficiently. In the 20th century, the concept of the reciprocating sprayer gained momentum, driven by the increasing demand for precise and efficient woodworking tools.

One of the earliest examples of a reciprocating spraying machine was the "spreader" developed by the German company "Hanser." This machine was designed to spray wood evenly over a surface, with its mechanism allowing for precise control over the spraying process. Over time, the concept evolved into more advanced designs, with the introduction of air compressors and other innovations that enhanced its performance.
