Double Roller Coater Description

Glass Surface Roller Coating Machine

Our glass roller coater is engineered to apply specialized glass coatings with exceptional precision. This coating machine ensures an even and thorough application without light leakage. The surface finish is smooth and uniform, with no oil accumulation at the edges or corners. Its special design not only scrapes away excess ink and coating but also recycles it, significantly surpassing traditional methods like spraying or screen printing. This enhances productivity and reduces the need for rework.

Main Applications

  • Cover glass for smartphones, tablets, automotive glass, and commercial displays.
  • Photovoltaic glass (solar glass).
  • Home appliance glass (screens, TVs, refrigerators, microwaves, etc.).
  • Architectural glass, decorative engineering glass, and art glass.
  • Smart home glass: furniture glass and switch panel glass.
  • Functional glass: heat-insulating, UV-protective, and conductive glass.

Working Principle

The glass roller coater operates based on a precise and efficient mechanism. The coating roller and the smoothing wheel are aligned parallel to each other and rotate inwardly at a consistent speed, creating a V-shaped space where the coating material is uniformly distributed. By adjusting the tightness between the coating roller and the smoothing wheel, we can control the thickness and uniformity of the coating material on the roller. As the glass moves forward on the conveyor belt at a steady pace, it makes appropriate contact with the coating roller. This contact transfers the coating material from the roller onto the glass surface evenly.

Configurations & Line Layout

The entire glass coating line consists of glass loading machine, roller coater, transfer conveyor, IR dryer, cooling system and glass unloading machine.

Roller Direction Details

The coating rolls can rotate in both the same or opposite directions to control film thickness and transfer efficiency.

Control System

Independent DC converter motors for conveyor belt, coating roll, and pressure roll ensure precise adjustment.

Frequently Asked Questions

Q1: What types of glass can the roller coater process?
It is suitable for a wide range of flat glass, including smartphone cover glass, solar glass, home appliance glass, architectural glass, and functional conductive glass.
Q2: How does the roller coater prevent coating accumulation on edges?
The machine uses a precise parallel roller design and an inward rotation mechanism that ensures an even application, scraping away excess coating to prevent accumulation at corners.
Q3: Is the coating material recycled?
Yes, the special design of the roller coater includes a recycling system that captures excess ink and coating, reducing waste and operating costs compared to spraying.
Q4: What is the thickness range of the glass that can be coated?
The standard working thickness for most models is between 3mm and 20mm, suitable for various industrial and commercial glass applications.
Q5: Can the machine handle different widths?
Yes, we offer multiple models with working widths ranging from 900mm up to 3400mm to accommodate different production line requirements.
Q6: What determines the thickness of the coating film?
The film thickness is controlled by the rotation speed of the rollers and the direction of rotation (same or opposite), as well as the tightness between the coating and smoothing rollers.
