Product Description

double Head Lacquer Sanding Machine

Lacquer sanding machine is a device that replaces manual polishing of the paint surface. It has significant effects on improving production efficiency, improving yield and reducing labor intensity. Since the surface coating of the primer is very thin, the process requires that the primer coating cannot be sanded through. Therefore, it is a special equipment with high precision requirements and an important equipment in painting equipment.

The Lacquer sanding machine generally consists of an overall frame, a workbench lifting system, a workbench conveying system, a pressing system, etc.

Purpose of Lacquer sanding machine

Primer sanding—After sanding, the unevenness of the workpiece surface can be eliminated to improve the smoothness and prepare for the topcoat process. This equipment can be used alone or in conjunction with PE paint coating and PU paint coating;

Thick edge sanding—After the plate stacking and edge spraying, the four sides of the plate surface will be thick, which can be eliminated by sanding;

Pretreatment sanding—The workpiece can be sanded before painting to eliminate the black edge phenomenon;

Composition of the assembly line, supporting the roller coating assembly line and the spraying assembly line, etc., realizes production automation and improves production efficiency.

Features of Lacquer Sanding Machine

1. Suitable for fine sanding of painted surfaces such as various furniture, wooden doors, cabinets, etc.

2. The equipment frame is welded from thick-walled rectangular steel pipes. After aging treatment, it is strong and stable and not easy to deform, which reduces the vibration of the body when sanding the plate and ensures the sanding accuracy.

3. The crossbeam is made of high-quality manganese steel, which is not easy to break and has high bending strength, which improves the stability of the sanding roller during operation.

4. The surface of the conveyor bed is mirror-finished with high flatness. After high-temperature aging, the material is stable and will not deform, and the accuracy and stability are extremely strong.

5. The rollers are tested by a dynamic balancing tester, and the correction accuracy can be controlled within the range of 1g-3g, which is 20% higher than the national standard, improving the sanding accuracy and avoiding the generation of ripples.

6. The integrated structure of the sanding roller and the pulley has stable performance, firm structure and convenient maintenance.

7. The original imported V-belt runs smoothly without jitter. The European special narrow V-belt structure is soft and can withstand a large preload, prolongs life and increases transmission power.

Working principle of Lacquer Sanding Machine

The sanding belt is connected into a ring shape according to the process, and is put on the sanding rubber roller. The steel roller is started on the device. The sanding belt maintains a certain tension. The sanding main roller rotates at the required speed, driving the abrasive cloth to rotate at a uniform speed; the workpiece is fed through the workbench. The system transports forward at a constant speed, appropriately adjusts the lifting height of the workbench, and the panels pass through the surface of the sanding belt under appropriate pressure, physically removing various defects on the surface of the primer. The surface of the primer is automatically sanded, and the surface can be sanded out through simple adjustments.

Application Of Lacquer Sanding Machine

Lacquer sanding machine is mainly used for primer grinding, paint thick edge grinding, and pre-treatment grinding. It is suitable for a variety of paint types, such as UV, PU, ​​PE, water-based paint, fluorocarbon paint and other flat plate primer layers. Primer sanding machine plays an important role in the woodworking industry, especially in panel furniture, wooden doors, wardrobes, cabinets, exterior wall insulation decoration integrated panels, wooden floors, decorative materials and other fields.

FAQ

A: It sands and polishes UV, PU, PE, NC, water‑based, and fluorocarbon paint surfaces on flat panels. Our ZZCHRYSO machine handles primer sanding, thick edge sanding, and pre‑treatment sanding (removing black edges). It’s ideal for panel furniture, wooden doors, cabinets, flooring, and decorative materials.

A: Two sanding heads (each with a sanding belt and contact roller) rotate at high speed. The workpiece moves on a conveyor under the sanding belts. The machine physically removes primer defects without sanding through the thin coating. An automatic thickness measurement system adjusts workbench height. The dust extraction system (8200 m³/h) captures sanding dust.

A: Three models: CRS‑MSG630R‑R (working width 630 mm), CRS‑MSG1000R‑R (1000 mm), and CRS‑MSG1300R‑R (1300 mm). Thickness range: 2–100 mm; min. working length: 270–310 mm; conveyor speed is variable frequency controlled; air pressure: 0.6 MPa; voltage: 380V 50Hz; dust extraction airflow: 8200 m³/h.

A: Heavy‑duty steel frame (thick‑wall rectangular pipes, aged for stability). Crossbeam made of high‑quality manganese steel for high bending strength. Conveyor bed mirror‑finished and high‑temperature aged to prevent deformation. Rollers dynamically balanced to 1–3g (20% above national standard) to avoid ripples. Sanding roller and pulley are an integrated structure for easy maintenance. Original imported V‑belts for smooth operation and long life.

A: Yes. The combination of automatic thickness measurement, variable frequency conveyor speed, and precise roller pressure control allows you to remove surface defects without cutting through the primer (which is only about 0.1 mm thick). The double head design also provides a gentler progressive sanding action.

A: The machine includes safety guards, emergency stops, and low air pressure protection. Dust extraction airflow is 8200 m³/h, keeping the work area clean and protecting operators from fine paint dust. The dust ports are sized appropriately for each model.

A: Daily: clean dust from belts and ports, check air pressure. Weekly: inspect belt wear, clean sensors, lubricate bearings. Monthly: check roller dynamic balance, calibrate thickness measurement system, test emergency stops. The integrated sanding roller and pulley design simplifies belt changes.

A: Panel furniture manufacturing, wooden door production, wardrobe and cabinet making, exterior wall insulation decoration integrated panels, wooden flooring, and decorative material processing. It can be used alone or integrated into painting lines (roller coating or spray lines).

A: Yes. It works with UV, PU, PE, NC, water‑based, and fluorocarbon paints. The variable frequency conveyor speed and soft rubber rollers adapt to different coating hardnesses and thicknesses. It’s also effective on melamine paper and raw wood pre‑treatment.

A: Absolutely. It includes automatic thickness measurement, variable frequency conveyor speed, and a dust extraction system that can be connected to a central collector. The machine can be placed between a roller coater and a drying tunnel or UV curing unit for continuous automated production.
