LJBZ2025 Automatic Vertical Laminated Insulating Glass Double Glasing Production Line 

Details Display

The whole insulating glass production line usually includes 7 parts: 

(from right to left)

1, The Loading section(with Low-E checking)  
2, The washing and drying section(can washing Low-E glass) 
3, The conveyor section  
4, The checking and assembly section  
5, The conveyor measure, and the sensor section 
6, The press part with gas filling  
7, The unloading section.

The second part: the washing and drying section.

In this glass cleaning section, there are three pairs of soft brushes and four pairs of water spray for washing and drying glass. The air knife is float designed, which part always keeps the right and suitable distance between the glass and air knife in the press and design section. ( Entirely as same as the LISEC ) 

The transfer wheel from this section: The front and back transfer wheel is all-direction moved, all actively transferred. Whatever the glass size is big or small, it always guarantees the glass pass through smoothly. ( Entirely as same as the LISEC ) 

The axle and bearing of brushes adopt all stainless steel, which could keep the machine can washing stabilized and using for a long time. The whole drying machine uses a sound insulation design, which could reduce noise pollution effectively.

The 6th parts: the pressing and gas filling section.

In this section, it could adopts online input the suitable gas proportion value, all the data could showed off on the touch screen, and during the gas filling processing, the touch screen can show off the whole gas filing process visually. However, how to show off the percentage of the argon gas filling on the touch screen online, is the importance technology on insulating glass producing. Jinan Lijiang Glass, which is the first and the only one manufactory, could master this technology very well from China. 

There is no doubt that it could be very useful for customers, when argon gas are filling, it will show off the whole processing on the screen. When it reach the customers setting data, It will alarm and stop immediately. So it not only can save the argon gas, but also can save the processing-time. By the way, the bottom of gas filling is our special structure.(Entirely as same as the structure of LISEC)  

Whole press and gas filling section are divided into five parts (per 750mm), when the small size glass (less than 750mm) pass through the pressing and gas filling section, only one part could work. When the difference size glass, which glass is more than 750mm but less than 1500mm, pass through the pressing and gas filling section, it will two parts work, no need the whole press and gas filling section work, to saving more the argon gas.

Main Feature

The coating inspection

To Avoid the Low-E glass put inverse side and Leave wheel marks or scratch low-e Coating, Jinan LIJIANG Glass uses coating inspection -metal film conductive. (others suppliers from China, usually use the photoelectric detection, and it's actually little hard to recognize for higher transparent)

The pressing box uses the high precision servo motor.

The servo motor could be accurately calculated the thickness of the Insulated glass and aluminum spacer. Compared with traditional hydraulic station. And also, it could guarantee the precise working pressure and protect the glass from damage, at the same time increasing the working speed.

Air floating technology - Optional

The front and back transfer wheel are all moved, all actively transferred. It can guarantee the big and thick glass pass through smoothly. The equipment adopts the new air – floating technology uses air to support glass and transfer glass. When glass is washed clearly from the washing machine, using air to transport the glass, it won't be contaminated. Ensure that the produced insulating glass is of the highest quality.

The first one to use adjustable points to ensure that the platen will never deform.

The whole equipment adopts CNC technology into the pressing board. It was designed the adjustable points inside the pressing board to keep the backplate straight all the time. In China, except LIJIANG, no more others suppliers could guarantee that the pressing board will remain vertical andstraight all the time after used over 10 or 20 years. 

It uses six soft (Low-E Glass) brushes with the 0.1mm diameter only.

It has 6 brushes which are all soft brush, could wash and dry more difference types and sizes ofr low-e glass, flat glass, tempered glass and so on. It has a diameter of less than 0.1mm bristles, never damage glass, especially for low-e glass cleaning.

The whole washing machine all uses 304 stainless steel materials

The whole washing and drying section adopt 304 stainless steel materials, including the plate and interior spare parts. The thickness plate can up to 4mm and the interior plate can be 8mm.The equipment performance is better and service life is much longer than other suplliers.

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 hollow line of other manufacturers, some use supporting rollers, and some 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 this discharging 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 air intake 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 air intake 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.
