Artificial many, labor intensity is big, low production efficiency；Two be select material be mostly it is complicated, for example：Chinese patent
CN2889770Y discloses one kind《Automobile sun-shading cover》, the material used in it is thermal insulation layer, the piece of upper and lower surface layer by middle part
Material is bonded to be formed, and wherein upper and lower surface layer is is coated with aluminium reflector layer on film, and described thermal insulation layer is to use bubble type polyethylene
Or polypropylene is fitted with foamed polyethylene and formed；Or described thermal insulation layer is with hardboard and polyethylene or polypropylene bubble type film
Laminating is formed, its thermal insulation layer it is complicated, thickness and weight are big, and cost is high, is difficult to deposit in smaller limited space in the car
Put.
The content of the invention
It is an object of the invention to provide a kind of simple production process, production efficiency is high, production cost is low, lightweight, Yi Cun
The lightweight sun shield and its production technology put.
The object of the present invention is achieved like this：
A kind of production technology of lightweight sun shield, comprises the steps：
(1) selection：Manufacture or selection upper, middle and lower layer be bonded successively with aluminum membranous layer, bubble film layer, aluminum membranous layer one
The sheet material of body formula；
(2) cut out：Sheet material selected by step (1) is cut into the outline of the sun shield of expansion；
(3) suppress：Be spaced with heat-sealing machine in sun shield it is hot-forming go out some vertical or horizontal fold lines, fold
Bubble film layer at line is by the soft lamella of thermal synthesis；
(4) trimming：Trim effluent or step (2) during because of heat seal and cut out irregular excess portion；
(5) pack：Tied up after the product of step (4) formation is folded with rope band or/and in packaging bag.
Above-mentioned rope band is the elastic band or tether of binding.
Above-mentioned elastic band is endless belt.
The outline of above-mentioned steps (2) sun shield is that base is straight, have the quadrangle of lower concave part, quadrangle in the middle part of top
Corner's rounding off.
Above-mentioned steps (3) pressing process include along sun shield annular periphery it is hot-forming go out flanging, described folding
Line insertion flanging.
The width of above-mentioned flanging and fold line is 5-20mm.
The thickness of above-mentioned bubble film layer is 2-7mm.
The compressing heat-seal temperature of above-mentioned heat-sealing machine is 50-260 DEG C.
The lightweight sun shield produced with a kind of production technology of above-mentioned lightweight sun shield.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that：
As long as the 1st, the present invention by sheet material cut out it is rear pressed on heat-sealing machine with the metal pattern bar after heating, production technology
Simply, labor intensity is low, production efficiency is high, production cost is low.
2nd, the present invention due to using bubble chamber film and aluminium foil as material of main part, foldable storage, using and convenient transportation, weigh
Amount is light, compared with prior art lightweight more than one times of the lightweight sun shield of same specification.
3rd, the product that the present invention is produced compared with prior art, because raw material and processing cost are low, the overall cost of product
It is low, it is adaptable to make the sun shield of vehicle glass.
Brief description of the drawings
Fig. 1 is the deployed condition schematic diagram of the present invention.
Fig. 2 is the schematic perspective view of the folded state of the present invention.
Fig. 3 is the partial sectional view of the sheet material of the present invention.
Embodiment
With specific embodiment, the invention will be further described below in conjunction with the accompanying drawings, referring to Fig. 1-Fig. 3：
A kind of production technology of lightweight sun shield, comprises the steps：
(1) selection：Manufacture or selection upper, middle and lower layer bonded successively with aluminum membranous layer 11, bubble film layer 12, aluminum membranous layer 11 and
Into integral type sheet material 10；
(2) cut out：Sheet material 10 selected by step (1) is cut into the outline of the sun shield 1 of expansion；
(3) suppress：With heat-sealing machine in the sun shield 1 interval it is hot-forming go out some vertical or horizontal fold lines 40,
Bubble film layer at fold line 40 is by the soft lamella of thermal synthesis；
(4) trimming：Trim effluent or step (2) during because of heat seal and cut out irregular excess portion；
(5) pack：Tied up after the product of step (4) formation is folded with rope band 50 or/and in packaging bag.
Above-mentioned rope band 50 is the elastic band or tether of binding.
Above-mentioned elastic band is endless belt.
The outline of above-mentioned steps (2) sun shield 1 is that base is straight, have the quadrangle of lower concave part 30, four in the middle part of top
