D) get crash roll and put into that mould is sheared, cold moudling, the demoulding obtains photography bag crash roll finished product.
Preferably, outside described flannelette, band is fine hair, and is inboard for weaving cotton cloth.The fine hair in the outside prevents dividing plate scratch photographic goods, and inboard convenient bonding with the EVA expanded material for weaving cotton cloth.
Preferably, described EVA expanded material is flat.Make size and the thickness of crash roll according to the size of photography bag, to adapt to different actual conditions.
Preferably, evenly smear with the adhesive of smearing below above described EVA expanded material.Evenly smear and be more conducive to the bonding of EVA expanded material and flannelette.
Preferably, the baking temperature of baking box is that 120 degree are to 200 degree.Through repeatedly constantly experiment, find oven temperature at 120 degree to 200 degree, the EVA expanded material neither can affect because of excess Temperature performance, also is beneficial to the moulding of EVA expanded material, and for reduce process time, Cost reduction.
Preferably, in baking box, the time of baking is 2 minutes to 4 minutes.Through repeatedly constantly experiment, find stoving time the scope of 2 minutes to 4 minutes, the EVA expanded material neither can affect because stoving time is long performance, also is beneficial to the moulding of EVA expanded material.
Preferably, the die cavity edges of mould is sharp edge.Directly the EVA expanded material is sheared from raw material, reduced post-production.
Preferably, the mould intracavity wall of mould is provided with corresponding die cavity for the shape according to photography bag crash roll.Bending impression or the decorating of photography bag crash roll form by the disposable compacting of mould, reduce post-production.
With further, described flannelette also can replace with oxford or velvet.
According to the inventive method, can make easily the crash roll that protection top layer and expanded material height are fitted, in conjunction with tight, difficult drop-off, long service life.Finished product is sheared, the surface configuration one-shot forming, reduces the post-production cost.
The specific embodiment
Below for specific embodiment describes the present invention, but not as limitation of the invention.
A kind of photography bag crash roll preparation method, its step comprises:
A) on the EVA expanded material and below smear respectively adhesive, the expanded materials such as sponge are not easy to the later stage and are pressed into fixing shape, so use the EVA expanded material, smearing adhesive is that fixedly flannelette is prepared, the crash roll that the method on fixing expanded material and protection top layer is made is made in employing, expanded material and top layer applying degree are not high, affect service life;
B) get above the EVA expanded material that two smooth being attached to of flannelette are coated with adhesive and below, fix flannelette, photography bag crash roll is tentatively made, be pasted on EVA expanded material upper and lower surface with flannelette, protection EVA expanded material is not damaged, and the fine hair of crash roll outer surface protects other products not by scratch;
The crash roll that c) will post flannelette is put the baking box baking into, makes EVA expanded material preheating deliquescing, is convenient to mould and is pressed into fixing shape, if directly crash roll is suppressed with mould, the EVA expanded material can be out of shape bounce-back, affects the moulding of crash roll;
D) get crash roll and put into that mould is sheared, cold moudling, the demoulding obtains photography bag crash roll finished product.
Preferably, outside described flannelette, band is fine hair, and is inboard for weaving cotton cloth.The fine hair in the outside prevents dividing plate scratch photographic goods, and inboard convenient bonding with the EVA expanded material for weaving cotton cloth.
Preferably, described EVA expanded material is flat.Make size and the thickness of crash roll according to the size of photography bag, to adapt to different actual conditions.The size of EVA expanded material is decided according to the size of baking box and mould, and the thickness of EVA expanded material is decided according to the actual demand size of crash roll.
