Description
Technical field
The utility model is related to a kind of equipment technical fields for producing light diffusing sheet, do not discharge discontinuously more particularly to a kind of
Extruder die head.
Background technology
Light diffusing sheet is by means chemically or physically, and being expert in track using light, it is different to encounter two refractive index
During medium, the physical phenomenon of refraction, reflection and scattering occurs, by adding inorganic diffusion on the Substrate basis such as PMMA, PS, PP
Agent or the artificial adjustment light of the array of organic light diffusing agent or the micro-feature structure for passing through substrate surface arrangement send out light
Refraction, reflection and the scattering of raw different directions so as to change the conduct route of light, realize that incident light is fully scattered and generate light with this
Learn the effect of diffusion.
At present, it when producing light diffusing sheet, is carried out using parallel dual-screw complex extruder or single screw extrusion machine
It is granulated, then the particle of Screw Extrusion is expressed by extruder in die head, is then passed through the die head of adjustable width, thickness
It spues, using three-roll formation, forms final light diffusing sheet.
This process seems simple, but is made using twin-screw complex extruder or using single screw extrusion machine
Grain, as long as being preset, then the speed of granulation is all certain, and by be granulated be expressed into extruder die head when
It waits, speed is also certain, that is, the amount of the master batch arrival extruder die head after thawing is constant always.In actual production process
In, if production is stablized, without being adjusted, it is a kind of extraordinary production status that this state, which is consistent, but if
It is related to tune machine, such as needs to improve the finished product thickness of light diffusing sheet, then if discharging speed is constant, it is necessary to will produce
Speed reduces；It is reduced again if necessary to the finished product thickness of light diffusing sheet, then if discharging speed is constant, it is necessary to by production speed
Degree improves；It is again if necessary that the width tune of the finished product of light diffusing sheet is narrow, then it needs to increase blocking to extruder die head；For another example fruit
It needs the width tune of the finished product of light diffusing sheet is wide, then needs to reduce blocking to extruder die head, and promote speed of production.But
Be, if to promote speed of production, there is one it is very serious the problem of because granulation is directly expressed into extruder by extruder
In die head, extruder die head, which directly will be granulated to spue, forms sheet light diffusing sheet finished product, this allows for promoting extruder die head
Discharge speed when, if the speed being granulated adjust it is improper, it is easy to granulation is caused to spue insufficient, the result finally directly resulted in
It is exactly that finished product light diffusing sheet is interrupted, thickness is inconsistent, the phenomenon that being even broken.If there is fracture, then need to adjust machine again simultaneously
Plate guiding is diffused, this needs to expend very big manpower, and serious waste production efficiency.
