The comparison of two design structures of  large-panel insulated glass production lines

For example, the maximum size of insulating glass required for a construction project is 3m*6m.

① The equipment structure: 

Extended size equipment + Inside combination technology + Two plate-pressing sections + Online argon-gas filling function

Each section of the production line needs to be designed and extended to the maximum size of the large-panel insulating glass, and the equipment size of all processing sections except the vertical glass washing and drying machine is upgraded to more than 6m. At the same time, the plate pressing section is made into two sections, and the processing method of combining the plates inside the plate is adapted to meet the requirement that the maximum length reaches 6m.

Advantage:
1. It can realize the one-time plate press molding of large plate insulating glass, and complete the argon filling function at one time, without the need for multiple processing operations;
2. It can realize simultaneous pressing and inflating of two pieces of insulating glass to improve production efficiency.

Disadvantages:
1. The production line occupies a large workshop area;
2. The price is relatively high.

Know More

②The equipment structure: 

Normal size equipment + Outside combination technology + Only one plate-pressing sections + Offline argon-gas filling function

It using the method of outside combination sheet + single plate press, it is necessary to combine two pieces of 3m*6m glass together outside the plate press, and the glass enters the plate press two or more times Pressing for the second time, and then manually inflating to complete the processing of insulating glass.

Advantage:
1. The equipment of the second structure is about 4 meters shorter than the double-plate press of the first structure, and the floor space is smaller.
2. The price is relatively lower than LIJIANG Glass LJBZ3370 Automatic Jumbo Size Insulating Glass Production Line.

Disadvantages:
1. The length of the plate press is not enough, it needs to be pressed twice or more times, which will cause uneven pressing of the first sealant butyl rubber coating and affect the sealing effect of the glass.
2. There is no way to fill the glass with argon gas online. The only way is to move the glass offline to punch holes and then manually inflate the gas. Manual inflation takes a long time, and it is difficult to meet the standard requirements of a gas content.
3. During the processing of large glass plates, multiple pressings are required, and the production efficiency will also be reduced.

Operating Steps

1. Turn on the power, turn on the operating switch on the control console, and press the oil pump to start.
2. Adjust the stroke. Pay attention to adjusting the stroke before use; and a gap must be set when the bending machine travels up and down to the bottom. Setting without gap will cause certain wear and tear on the bending machine equipment.
3. Selection of the notch of the bending machine. The selection basis is: the thickness of the glass plate is about 8 times the width. For example, if the thickness of the glass plate is 5cm, then the notch needs to be 40cm.
4. Manually or electrically fine-tune the stopper behind the bending machine.
5. Press the foot pedal switch to perform bending.
6. During the processing, the status and processing effect of the glass must be observed at all times to prevent equipment failure or defective products.
7. When the bending machine stops working, turn off the operating switch on the operating table, then turn off the power, and clean the work surface of the bending machine to make the surface clean and tidy for next use.

• The buytl cylinder adopts the pull-up structure, which is convenient for changing the butyl extruder coating.

Operation Steps

The following steps should be followed before and after each operation:

1. Start the conveyor belt

Adjust the conveyor belt to the appropriate speed, with an adjustable range of 8-30m/min.

2. Adjust the position of the rubber extrusion head

According to the width requirements of the spacer, adjust the distance between the two extrusion heads, the range is 6-16mm. When adjusting, the spacer (frame) should be centered with the small pressure wheel and the butyl extrusion nozzle, and the positions of the conveyor belt frame, butyl extrusion seat, and butyl extrusion head should be adjusted according to the height of the adhesive tape.

3. Butyl extruder temperature adjustment before work

Generally, the heating control switch is turned on about 1-2 hours before work, and the glue head temperature is set to 120-140℃ and the glue tank temperature is 110-120℃. Since the heating temperatures and process parameters specified for butyl rubber produced by various manufacturers are different, the above heating temperatures and times are for reference only.

4. Adjustment of opening and closing of the butyl extruder valve

After the heating system reaches the set temperature, do not open the hydraulic station first, but proceed as follows:

Process time setting:

According to the screen prompts, switch to the screen that needs to be adjusted, press the SET key, and the adjustable value will flash. The "←, →" keys change the position of the value; press the "↑" key to increase the value; press the "↓" key to decrease the value. After setting, press the ENT key and the data will be automatically stored, otherwise, the data will remain at the original value.

A. Adjust the time of the right pressing wheel: Make the front end of the spacer frame (strip) on the conveyor belt and the center of the extrusion head, so that the right pressing wheel presses on the aluminum spacer frame (strip). Before the end of the spacer frame (strip) passes through the right pressure wheel, the right pressure wheel can be lifted smoothly, which is very important for the bent spacer frame.

B. Adjust the time of the left pressing wheel: make the front end of the spacer frame (strip) on the conveyor belt, and make the left pressing wheel press on the aluminum spacer frame (strip). Before the end of the spacer frame (strip) passes through the left pressure wheel, the left pressure wheel can be lifted smoothly, which is very important for the bent spacer frame.

C. Adjust the butyl extruder spraying time: When the front end of the spacer frame (strip) is on the conveyor belt and is in the center of the butyl extrusion head, the butyl valve cylinder moves and the buytl valve opens; when the end of the spacer frame (frame) passes the butyl nozzle, close the butyl valve, no excess butyl leaks out.

5. Turn on the hydraulic station:

Before opening the hydraulic station, check the relative positional alignment of the butyl extrusion piston and the center of the butyl cylinder to ensure that the butyl extrusion piston can be correctly pressed into the butyl cylinder. Otherwise, damage to the butyl cylinder and the oil cylinder will occur. When the pumping station starts, the cylinder lift switch should be adjusted to the middle position (zero position). At this time, the pressure regulating valve should be in the open state. After the pumping station starts, gradually adjust the pressure regulating valve to increase the system pressure to the working pressure, but The working pressure shall not exceed 18MPa. When the room temperature is too high in summer and the hydraulic station works for a long time, the temperature will rise too high and the hydraulic oil will become thinner and lose working pressure. At this time, the hydraulic station should be suspended and restarted after the oil temperature drops.

6. Butyl extruder injection

A. Adjust the cylinder lift switch to the middle position and start the hydraulic station. When the hydraulic station starts and stabilizes, turn the cylinder lift switch to the "up" position to lift the cylinder piston away from the rubber tank and reach the highest position.

Note: If there is still butyl left in the glue tank and the piston of the butyl tank is not lifted after operation, the piston of the butyl tank should be heated to the specified temperature before lifting, otherwise the equipment will be damaged.

B. Start operating the swing mechanism

First, lift the piston of the butyl tank to leave the butyl tank, push the cylinder by hand to leave the cylinder mouth, and then insert the butyl ingot. After completion, reset the cylinder piston.

7. Air pressure adjustment:

The pressure of the doublet shall not be less than 0.6MPa. The air pressure of the swing motor that drives the small pressure wheel is individually adjusted to 0.15-0.4MPa by the pressure regulating valve.
