The insulating glass production line is a type of glass deep processing equipment, which is mainly used to process and make insulating glass.
Introduction to terms
The insulating glass production line is a type of glass deep processing equipment. It is mainly used to process and make insulating glass. The original glass pieces are cut and then entered into the insulating production line.
Mainly through washing, drying, making the spacer frames, filling with desiccant, first sealing (coating with butyl extruder sealant), Inspection, frame closing, tablet pressing, second sealing (polysulfide sealant or silicone sealant), and tablet unloading. The processed products are of high quality and the processing speed is very fast.
The insulating glass production line mainly has four sections: the glass loading and unloading section, the washing and drying section, the inspection section, and the plate pressing section. The four sections are all installed vertically at the same inclination angle. They are compact in structure, economical and practical, high in efficiency, and easy to maintain. The washing tank is made of stainless steel, and the transmission rollers are acid and alkali-resistant rubber rollers; the glass washing situation can be easily observed at any time through the organic glass window; the feeding section and the washing and drying section are driven by manual step-less speed regulating motors, and the glass is driven by the best the speed runs smoothly. The drying section uses a strong wind-inclined air knife to dry the glass surface. The inspection section is equipped with light tubes, which can check the washing quality of the glass; the combined section is equipped with glass positioning and aluminum frame positioning devices, which can complete the functions of glass positioning and aluminum frame positioning. The glass is supported and transported by the transmission rubber roller. The transmission roller is driven by the motor (roller section motor) through the frequency converter and the sprocket. The glass enters this section from the cleaning and drying section at a low speed. After passing the inspection, it accelerates to the next work. section to improve work efficiency; the frequency converter controls the running speed of the speed-regulating motor in this section, and the photoelectric switch controls the glass to enter the next working section. The washing waterway system of the insulating glass production line is a circulation system. The water tank is equipped with a constant temperature water heating device, and the water temperature can be automatically maintained within a reasonable range.
Water is drawn from the water tank by a water pump and sprayed onto the glass surface through the spray pipe. After cleaning the glass, it flows back to the water tank for recycling. If the water quality is poor, a water treatment device (prepared by the user) needs to be equipped. The water will enter the water tank after treatment and be recycled according to the above steps.
Airpath system: The fan passes through a pair of inclined air knives to dry the glass.
Installation conditions
The factory building where the insulating glass equipment is installed should have an air source and 380V/220V (50Hz) AC power three-phase four-wire power supply configuration, that is, three-phase live wire and one phase neutral wire; solid concrete floor; industrial tap water source, drainage ditch, and site clean and dust-free.
Insulating glass production lines are divided into fully automatic, semi-automatic, airbag type, rotary type, and large plate type according to process, equipment, and functional characteristics. Each type has different characteristics, such as degree of automation, production efficiency, investment cost, and scope of application. Which type to choose needs to be evaluated based on product requirements, production scale, budget, and market demand.
The types and differences of insulating glass production lines are mainly divided according to their process flow, equipment configuration, and functional characteristics. The following are several common types of insulating glass production lines and their differences:
These are the common types and differences of insulating glass production lines. The specific type of production line to choose needs to be comprehensively evaluated and selected based on product requirements, production scale, investment budget, and market demand.
Main production equipment:
With the development of the glass deep processing industry and people's deepening understanding of the advantages and performance of insulating glass, the application scope of insulating glass is constantly expanding, in glass curtain wall buildings, train side windows, freezer display cabinet sliding windows, etc. In addition to being widely used, it has now begun to enter the homes of ordinary people. This is mainly due to the application of insulating glass, which not only improves the thermal and sound insulation effects of the building but also simplifies the structural design of ventilation and heating facilities. This not only reduces the cost of building decoration but increases the effective practical space in the building.
As the application fields of insulating glass continue to expand, people's quality requirements for insulating glass are getting higher and higher. How to seize the market development opportunities of glass deep processing and provide high-quality and reliable insulating proportions has become a problem that insulating glass manufacturers often study.
LIJIANG Glass first introduces the types of insulating glass and the five indicators in the insulating glass industry standards:
The classification
There are two common types of insulating glass currently on the domestic market:
Aluminum strip type insulating glass: This type of insulating glass was introduced in the United States in the 1980s and is relatively mature, but the processing technology is complex.
Rubber strip type insulating glass: This type of insulating glass has just started in developing countries. It was jointly developed by FENZI and Swiggle Super Spacers. However, the processing technology is relatively simple, so it has a wide range of applications and is promoted quickly.
Five indicators in the insulating glass industry standards
According to the testing standards of the insulating glass industry, how to arrange the production of glass deep processing to meet the processing requirements of insulating glass? Since the two types of insulating glass have many similarities in the process flow, let's first briefly analyze their common process flow.
Glass cutting and blanking
The original glass is generally colorless float glass or other colored glass, sunshade glass, tempered glass, or laminated glass, and the thickness is generally 3mm~12mm. The above glass must comply with the regulations on first-class and superior glass in the insulating glass industry standards. , it can be used only after passing the inspection. Glass cutting can be done by hand or machine, but the size requirements should be ensured. During this cutting process, workers should always pay attention to the fact that there should be no scratches on the glass surface, that the inner quality should be uniform, and that there should be no obvious defects such as bubbles or lanes.
Glass washing and drying
Glass washing must be carried out with automated equipment because manual washing cannot guarantee the washing quality. Before washing, check that the glass is not scratched. To ensure the adhesion between the sealant and the glass, it is best to use deionized water. In addition, to ensure multiple recycling of washing water and save water resources, the water can be filtered to ensure long-term use. The washed glass must pass a light inspection to check whether there are water droplets, water stains, and other stains on the glass surface; if there are water droplets, water stains, and other stains, the machine operating speed, heating temperature, air volume, and brush clearance need to be inspected. Adjust until perfect results are achieved. The washed glass should be assembled into insulating glass within 1 hour. In addition, it is necessary to ensure that there is no friction or scratch between the glass and the glass. It is best to have a semi-finished glass storage trolley at the production site to separate the glass sheets from each other.
Assembly of rubber strip type insulating glass and aluminum strip type insulating glass
Strip-type insulating glass assembly:
(1) Environmental requirements: The processing temperature of strip-type insulating glass should be between 10℃~20℃ in winter and between 20℃~30℃ in summer.
(2) Relative humidity requirements: Since the strip-type insulating glass desiccant is in powder form and the desiccant works slowly after being evenly mixed with butyl glue, the relative humidity of the strip assembly area should be kept low.
Aluminum strip type insulating glass assembly:
(1) Environmental requirements: The temperature should be between 10℃~30℃.
(2) Relative humidity requirements: This type of insulating glass has slightly lower requirements for relative humidity, which is sufficient under normal conditions.
However, it should be noted that the molecular sieve desiccant should be qualified products from regular manufacturers to ensure the effective use of the molecular sieve desiccant. It is best to use the molecular sieve desiccant within 24 hours after opening. Because polysulfide rubber has greater air permeability and poor sealing, double sealing is required. Generally speaking, for the bonding between insulating glass and spacers, butyl extruder coating is used as the first seal, which plays the role of isolating gas; polysulfide glue is used as the second seal, whose main function is bonding, and secondly. It's the air barrier effect. The practice has proved that the service life of single-pass sealed insulating glass is only about 5 years, while the service life of double-pass sealed insulating glass can be as long as 20 or even more than 40 years. Therefore, the development of double-pass sealed insulating glass is the general trend.
Glass tablets
When pressing strip-type insulating glass sheets, attention should be paid to aligning the edges of the sheets. When pressing, leave a small opening at the back to allow the gas after drying the molecular sieve to escape from the small opening, and then seal it immediately after pressing. At this point, the processing of strip-type insulating glass is completed.
For aluminum strip type insulating glass, after joining the sheets, there should be a distance of 5mm~7mm between the outer edge of the aluminum frame and the edge of the glass, which is used for applying the second sealant; and the polysulfide glue should be applied evenly along one side to prevent If bubbles are generated, scrape off the residue on the glass surface after coating. At this point, the processing of aluminum strip insulating glass is completed.
Placement of insulating glass
Whether the insulating glass is placed correctly or not will also have an impact on the final quality of the insulating glass, whether in production, transportation, or glass application. When storing insulating glass, first of all, the design requirements of the stacking rack must take into account the characteristics of the insulating glass. The stacking rack must have a certain inclination, but the bottom plane and the side should always maintain 90° to ensure that the two pieces of insulating glass are The bottom edge can be placed vertically on the stacking rack. Also note that the bottom of the glass should not be stained with oil stains, lime, and other solvents, as they can corrode the second sealant of the insulating glass to varying degrees, thereby affecting the sealing performance of the insulating glass.
Debugging method
1. Place the insulating glass production line lightly in the installation position, and place the positions of each section of the insulating glass production line in the correct order.
2. Level the fuselage. Adjust the height of the leveling bolts on the base of the machine so that the supporting surfaces of the transfer roller and the supporting nylon wheel are at the same height, the backing wheel on the inclined frame is coplanar, and each section is relatively parallel, and then tighten the nut.
3. Connect and tighten the parts that need to be connected between each section, and connect the transmission chain from the loading section to the washing and drying section. Place the wind fan and water tank correctly, and connect the air ducts and water pipes according to the water and air system diagrams.
4. Comprehensively check whether all fastener connections of the machine are loose due to transportation vibration, and tighten them one by one (especially whether the connections of each terminal block are loose).
5. The grounding wire should be a soft copper core yellow-green insulated wire with a cross-sectional area of not less than 4 square millimeters, and the grounding resistance should not be greater than 4 ohms.
6. Connect the air source and check whether the pipeline is smooth and damaged. The air source pressure requirement is 0.6~0.8Mpa.
7. Turn on the power and test whether the rotation direction of each motor is correct and whether the transmission sprockets of each section are flexible and stable.
8. Clean the entire machine and tidy up the work area.
With the continuous promotion and application of insulating glass, people's requirements for insulating glass are getting higher and higher. As glass deep processing practitioners, we should constantly improve the processing technology of insulating glass, strive to improve the technical level and product quality of glass, and promote the development of insulating glass in a higher, newer, and stronger direction.
