Description
Technical field
It the utility model is related to the technical field of paper mould preparation, and in particular to a kind of swollen type of paper mould wet pressing rubber
Device.
Background technology
Paper mould also known as paper support, be with carton leftover pieces, newsprint, white pure paper pulpboard (wood-pulp board, sugarcane pulpboard,
Bamboo pulp plate etc.) etc. be raw material, by pulping and allocate the slurry of proportional concentration, slurry on the numerical control mould of customization,
Through vacuum adsorption molding, the wet base of forming handles through drying, hot pressing integer and trimming and forms variety classes and purposes again
Environment-friendlypaper paper product.
The production process of paper mould is discharged without waste water, waste gas, and production process is recycled with water seal.It is main used in production
Raw material are waste paper, and abundance, cheap main raw material(s) are waste paper, and abundance, price are low, and the synthesis for belonging to waste is opened
Hair utilizes.Paper mould completes its shockproof guarantor of buffering to packed article during the commodity circulations such as storage, transport, sale
After protecting mission, its discarded object recyclable regenerative as common paper utilizes, even if abandoning in natural environment also paper one as
Sample is easy to rot to resolve into string.
Paper mould anti-vibration protected to the buffering of packed article is elastic and its well-designed sky by fiber in itself
Chamber geometry is realized.Shown by substantial amounts of practical application and test, its protective foot to packed article is to substitute
Polystyrene plastics foam, it is to solve " white pollution " preferable environment-friendly type substitute.
The manufacturing process of paper mould：The manufacture craft of paper mould, divide dry-pressing manufacture craft and wet pressing manufacture craft.
Dry-pressing manufacture craft：
1) pulp board is added water after pulping by, allocates the slurry of proportional concentration；
2) slurries are on the suction oar mould of customization, and through vacuum adsorption molding, the demoulding dries；
3) the wet base of formings, the dry body of water about 20% is fabricated to by drying (dry or dry)；
4) dry bodies pass through optical mode hot pressing shaping, turn into finished product after trimming.
The characteristics of dry-pressing manufacture craft：Made first, substep making is noncontinuity；Second, it is not high to make precision.
Wet pressing manufacture craft：
1) slurrying：By pulp board plus water after pulping, the slurry of proportional concentration is allocated；
2) is molded：Slurry is on the suction oar mould of customization, through vacuum adsorption molding；
3) cold extrusions：The wet base of oar mould adsorption forming is being inhaled, with cold-extruded press-fitting mould, the moisture in wet base is being extruded, together
When the wall thickness of wet base is squeezed it is thin；This cold extrusion is hard fashion of extrusion；
4) is hot-forming：Wet base after cold extrusion is transferred to heat supply network mould, and hot optical mode matched moulds, in certain pressure and
At temperature (about 150 degree), by the hot pressing of about 90 seconds, the demoulding.
5) trimmings：Through trimming after the demoulding, you can as finished product.
The characteristics of wet pressing manufacture craft：First, continuous making is that shaping-cold extrusion-hot-briquetting modeling process is connected in equipment
Continuous progress, automaticity is high；Second, it is higher to make ratio of precision；Third, the product of low-angle side wall, i.e. draft angle can be made
Degree can be with very little, about 1 degree.
But the difficult point of wet pressing manufacture craft is：Decrement≤0.8 millimeter when paper support side wall is hot-forming, during cold extrusion
Decrement≤0.6--0.8 millimeters because excessive decrement, can be caused in matched moulds " pusher ", therefore paper support side wall can produce
Raw crackle.Example：Paper support be hot pressed into after 1 millimeter of sidewall thickness：Then inhale about 2.4 millimeters of wet base sidewall thickness after oar, cold extrusion
About 1.7 millimeters of wet base sidewall thickness afterwards.
Therefore, will except having to slurry (such as concentration, beating degree) when making side wall low-angle (demoulding angle) product
Beyond asking, there is higher requirement to the wet base of cold extrusion before hot pressing：The sidewall thickness of wet base after cold extrusion, after hot-forming
The sidewall thickness of dry body is big≤and 0.8 millimeter.Example：Paper support be hot pressed into after 1 millimeter of sidewall thickness, the then wet base after cold extrusion side
Wall thickness≤1.8 millimeter.
Common practice is in the industry of the wet base cold extrusion of paper support, and after setting amount of compression, wet base is adsorbed on midge mould, with
Cold extruding die matched moulds under stress, wet base moisture is extruded, while side wall is thinned to hot extrusion molding requirement.Technique above is done
Method, the thicker paper support of wall thickness can not be made, thin-walled paper support is yielding, greatly limit his application.
Technique way above, can not make the thicker paper support of wall thickness, and thin-walled paper support is yielding, greatly limit his
Application.
