LIJIANG Glass adopts the front and rear squeeze wheel drive, the front and rear wheels are powered, and glass of any size and thickness can pass through smoothly; like the drying section of the insulating glass production line of other manufacturers, some use supporting rollers, and the rear wheel is used as the driving wheel, and the front wheel is used as the driven wheel. These methods are easy to turn over when processing small-size glass, and easy to move when processing large-size glass, which affects the processing efficiency.
LIJIANG Glass uses a round-head Low-E Glass coating detection probe instead of a needle-type detection probe, which will not pierce the glass; it also does not use the photoelectric detection probe commonly used by other manufacturers. The disadvantage of photoelectric detection is that it encounters some high-transparency Low-E Glass is easy to detect the coating.
in the third section, one piece of 2.5-meter glass can be parked at the same time, and two pieces of 2-meter glass can be parked at the same time.
The glue depth of the aluminum frame installation of the upper frame section can be adjusted through the digital handle, which is simple and intuitive.
The fifth section, which could called the Flat Press Loading Section, measures the thickness of the glass and aluminum frame, mainly to provide accurate data for the sixth section of inflation and pressing, because the inflatable beam and the pressing section need servo motors to control the pressing distance, and the glass of the same specification does not need Measure glass thickness and aluminum frame thickness each time.
What structure is used by other manufacturers, and what are the advantages?

The inflatable beam and the conveyor belt in the pressure section of the LIJIANG Glass inflatable plate adopt an integrated synchronous belt structure. This method has better sealing performance, and the insulating glass is not easy to leak during the process of inflating and assembling; other manufacturers use a separate structure for the transmission wheel and the inflating beam. In this way, the bottom is prone to air leakage during the inflating and closing process.
The air hole in the pressure section of the LIJIANG Glass inflatable plate adopts the method of direct blowing air into the inside of the two pieces of glass, the argon-gas intake filling speed is faster, and the inflating effect is better when processing large-format glass; compared with other manufacturers, the air intake is reflected to the aluminum bar In the way of filling the inside of the two pieces of glass, the argon-gas intake filling speed is relatively slow. When processing large-format glass, the wide aluminum strip will block the flow of gas, and the gas filling concentration is difficult to reach the standard.
The plate pressing plate surface of the LIJIANG Glass inflatable plate pressing section can be adjusted individually, divided into 74 points for adjustment.
