Molecular sieve spacing bar, manufacturing method and equipment

Abstract

The invention belongs to the technical field of glass deep processing, and discloses a molecular sieve spacing bar, a manufacturing method and equipment. A molecular sieve in the molecular sieve spacing bar is bonded into a strip-shaped object through an adhesive; the outer surface of the molecular sieve is wrapped with a layer of adhesive, and the spacing bar which takes the molecular sieve as a supporting framework and has a certain porosity is formed through mutual bonding of the adhesive; and the spacing bar is directly bonded on glass in an online manufacturing and online placing mode to form a spacing frame. According to the molecular sieve spacing bar, the moisture absorption function is added to the spacing bar, the supporting function is added to the molecular sieve, the molecular sieve and the spacing bar are combined into a whole, the existing molecular sieve filling process is omitted, and therefore the production cost is reduced; various additives can be added into the spacing bar, and various functional strips can be compounded, so that the performance of the spacing bar is improved; and the cost of the spacing bar is not higher than that of an existing lowest aluminum alloy strip, and the performance of the spacing bar is not lower than that of an existing highest-end TPS strip and TSS strip.

Description

technical field [0001] The invention belongs to the technical field of glass deep processing, and in particular relates to a molecular sieve spacer, a manufacturing method and equipment. Background technique [0002] At present: The energy consumption of buildings has accounted for more than 30% of the total energy consumption of the society. Improving the thermal insulation performance of doors and windows is the main way to promote energy saving in buildings; due to the good heat insulation and sound insulation performance of insulating glass, it is low in cost, large in production capacity, and easy to install and use. Convenient, so it has been widely used. The spacer frame is one of the important components of the insulating glass. It not only connects two pieces of glass to form a hollow cavity, but also plays a role in sealing the hollow cavity, and is also related to the wind pressure resistance of the insulating glass. The spacer frame is generally made of spacer s...

AI Technical Summary

Problems solved by technology

The spacer frame is generally made of spacer strips by splicing or bending. The spacer frame made by splicing has been gradually eliminated due to many seams and poor sealing performance; the existing domestic spacer frames are mainly made of aluminum alloy. The bar is made by a bending machine. The main disadvantage is that the thickness of the aluminum alloy bar is about 6.5mm. When bending, the inner surface is under pressure, the outer surface is under tension, and the two sides are bulging outward. Therefore, not only the aluminum alloy bar is required The strip has good ductility, and must have a certain wall thickness, otherwise it is easy to deform or break; if the wall thickness is large, not only the cost is high, but also the thermal conductivity is good and the heat insulation performance is poor; and the bending radius is relatively large, It does not match the right angle of the glass, and the corners are prone to lack of glue when applying structural glue with a glue machine, and need to be repaired manually

In order to absorb the water vapor in the hollow cavity and prolong the service life of the insulating glass, molecular sieves need to be filled in the spacers. The existing technology is to use a molecular sieve filling machine to fill the outer surfaces of the two sides of one corner of the spacer frame after the spacer frame is made. Pour molecular sieves into the cavity of the spacer by punching holes respectively, and then seal the filling hole with butyl rubber. Sealing with glue, but the sealing can only prevent the molecular sieve from flowing out and cannot guarantee watertightness and airtightness; when the existing molecular sieve is filled, dust is likely to be generated due to the wear and collision of the molecular sieve during transportation, and the dust will enter the spacer along with the molecular sieve During the transportation of glass, dust will also enter the hollow cavity through the moisture absorption holes on the spacer, thus polluting the insulating glass

After the spacer frame is filled with molecular sieves, butyl rubber is applied on one side and the other side of the spacer frame. The disadvantage is that the four sides of the spacer frame need to be glued separately. When the butyl rubber is more and sometimes less, it is easy to break the glue and cause the seal to fail, and it is difficult to apply glue when the size of the spacer frame is large

The existing spacer frame production, molecular sieve filling, butyl rubber, and spacer frame placement generally use semi-manual and semi-mechanical methods, which require about 3-4 people, and there is no equipment connection, and transportation is required in the middle, so the degree of automation is relatively high. Low, the labor intensity of workers is relatively high, and the product quality is not stable

[0003] The existing spacers can be divided into factory-made and on-site production according to the production method. The factory-made spacers are finished products, such as aluminum spacers, etc., and then made into spacers at the insulating glass production site. The disadvantage is that it takes up labor. Many, poor heat insulation performance, cannot be mechanized installed on the glass, etc.; the spacers made on site are disposable spacers, such as TPS warm edge strips, etc., although it can solve the main problem of aluminum spacers, but its shortcomings The equipment is expensive, the investment is large, the price of the materials used is high, and the cost of the spacer is several times that of the ordinary spacer, so it cannot be popularized and applied on a large scale

[0005] (1) Existing spacers need to punch holes on the outer surface of the spacer frame, which destroys the airtightness of the spacer frame. The plugging can only prevent the outflow of molecular sieves and cannot guarantee watertightness and airtightness.

[0006] (2) The existing molecular sieve spacer is easy to enter the dust during the preparation, which will pollute the insulating glass

[0007] (3 The existing spacer frame production, filling molecular sieve, butyl rubber, and spacer frame placement generally adopt semi-manual and semi-mechanical methods, which require about 3-4 people, and there is no equipment connection, and transportation and automation are required in the middle The degree is relatively low, the labor intensity of workers is relatively high, and the product quality is not stable

[0008] The difficulty in solving the above problems and defects is that the existing spacers are difficult to simultaneously meet the requirements of small equipment investment, low production cost, good heat insulation and sealing performance, automatic winding, and high mechanization.
