Background technology
In daily life, mattress or other mats are conventional liner articles for use, for mattress, mattress is to ensure that user secures good health and comfortable sleep and the one article between human body and bed used, for reaching the requirement making people feel comfortably cool, mattress one is which kind of sleeping posture no matter requirement be in, and the backbone of people can keep straight unfolding; Two is that requirement pressure is impartial, and people's whole body of overlieing can fully be loosened.But, current all kinds of mats, although kind, material are various, substantially still with spring or soft-filler for main formation, be difficult to meet the demands in comfort level, and relative complex when manufacturing.
Summary of the invention
In order to overcome the defect of prior art, providing the liner that a kind of structure is simple, easily manufactured, neither too hard, nor too soft, the invention discloses a kind of loose elastic mattress and manufacture method thereof.
The present invention reaches goal of the invention by following technical solution:
A kind of loose elastic mattress, comprise plastic optical fibre, it is characterized in that: plastic optical fibre is at least divided into different three groups of bearing of trend, plastic optical fibre all undulate extends, wherein have the extension plane of three groups of plastic optical fibres orthogonal between two, often the spacing organized in plastic optical fibre between each bar plastic optical fibre is not more than 10mm, and the point of intersection of each group plastic optical fibre adopts hot melting cohesion, the envelope of all plastic optical fibre end points and outermost plastic optical fibre outer rim is cuboid, and described cuboid is elastic mattress.
Described loose elastic mattress, is characterized in that: the diameter of plastic optical fibre is not more than 5mm; Plastic optical fibre is hollow fibre, and plastic optical fibre internal diameter is 50% ~ 80% of external diameter; The density of elastic mattress is 300g/m
3~ 800g/m
3.
The manufacture method of described loose elastic mattress, is characterized in that: implement successively as follows:
Granular plastics are dropped into hopper as raw material, raw material is heated to 190 DEG C ~ 200 DEG C through hopper input baking oven, and to make with plastics be molten condition, the plastics input extruder of molten condition, through extruder clamp-on become thin filament-type plastic after mould after extrude from the wire vent hole of mould again, tank is provided with below mould, two relative format rolls are provided with in tank, namely filament shape and the plastics of molten to immerse in tank and cooled fast by water between two format rolls after extruding from the wire vent hole of mould, in quick cooling procedure, the filamentous plastics of original multiply are curled and are wound around mutually, thus formation extends and elastic mattress adhered to one another again separately along horizontal plane and vertical plane, spacing between two format rolls and the thickness of elastic mattress, elastic mattress is pulled machine travel effluent trough subsequently, Cutting platform is sent into after two roller roller rolls, cut into required size, complete the manufacture of elastic mattress.
The manufacture method of described loose elastic mattress, is characterized in that: the particular plastics as raw material selects polypropylene particles, and the quantity in mould wire vent hole is not less than 300, and the hauling speed of hauling machine is 0.1mm/sec ~ 20mm/sec.
Manufacturing process of the present invention is simple, and the heating-up temperature of reasonable adjusting baking oven is applicable to different plastics, regulates the thickness of the spacing regulating stretch pad between two format rolls, regulates density and the sponginess of the hauling speed regulating stretch pad of hauling machine.Elastic force of the present invention is moderate, and as mattress, after human body is lain down, elastic deformation can occur mattress is fitted human body, comfort level is good, is unlikely to again to cause discomfort because of too soft, and simultaneously material is loose and porous structure, light weight and good springiness, and elastic force keeps lasting.
The invention has the beneficial effects as follows: structure is simple, easily manufactured, neither too hard, nor too soft, applied widely.
