Description
Technical field
Light diffusing sheet involved in the present invention produces and processes field, specially the trimming recovery process of light diffusing sheet.
Background technique
Light diffusing sheet is by means chemically or physically, and being expert at using light, to encounter two refractive index on the way different for diameter
When medium, the physics that refraction, reflection and scattering occurs is imagined, inorganic by adding in the Substrate basis such as PMMA, PC, PS, PP
Or organic light diffusing agent or by the artificial adjustment light of array arrangement of the micro-feature structure of substrate surface, make light
Refraction, reflection and the scattering of different directions realize that incident light sufficiently dissipates color and generates light with this to change the travelling route of light
The effect of diffusion is learned, light diffusing sheet is widely used in liquid crystal display, LED illumination and imaging display system.Its major function
It is to scatter incident light sufficiently, realizes softer, uniform radiation response.
In the flow forming process of light diffusing sheet, since the light diffusing sheet Forming Quality of widthwise edges is poor, so to lead to
Cross the using effect that the edge excision of light diffusing sheet is guaranteed entire light diffusing sheet by trimming device.The production of traditional light diffusing sheet
In technique, often the edge of light diffusing sheet is got off by the saw blade sawing of 3mm, is easy to produce the break flour pollution workshop ring of splashing
Border, next break flour are difficult to Collection utilization and raw material availability are caused to decline；Secondly, the rim charge after traditional light diffusing sheet trimming is scattered
In workshop beside sawing machine device, save bit by bit it is a certain amount of after again by workshop operator collection be transported to Material disintegrator concentrate carry out
Particle recycling.In traditional edge recycling technique, the rim charge by sawing machine often accumulates the excessive walking smooth degree for influencing operator,
Operator even is tripped, brings unforeseen hidden danger to the personal safety of operator.The light diffusing sheet rim charge being packed together
The rim charge that larger space aggravates the dirty and messy degree in workshop, and stores together is occupied to be easy incorporation impurity or spread with different types of light
The mixing of edges of boards material brings difficulty for subsequent recycling.
In order to solve the above-mentioned technical problem, it the invention proposes the trimming recovery process of light diffusing sheet, specifically includes: trimming
Recovery process, rim charge pre-separation, rim charge separation, rim charge transmission and particle carry out light diffusing sheet by blade of carving knife non-penetrating
Formula cutting and subsequent crack propagation process are completely separated rim charge with light diffusing sheet, and the rim charge cut is transmitted in Material disintegrator
Real-time particle is carried out, instead of traditional sawing machine sawing rim charge, the way of unified particle is artificially collected, improves shopwork environment, keep away
Exempting from rim charge pollution can not recycle, and trimming recovery process realization of the present invention is increasingly automated, substantially reduce light diffusion
The production cost of plate and production cycle.
Summary of the invention
The trimming recovery process of light diffusing sheet, specifically includes:

Cut the art knife that tool is thickness 0.2mm or so；Non-penetrating type, which is carried out, using relatively thin art knife cuts avoidable break flour
Generation, improve stock utilization while improve shopwork environment.
Rim charge pre-separation: it by the light diffusing sheet cooling after the cutting of non-penetration and rolls, expands cutting crack depth
Exhibition, cooling temperature are 0 DEG C~30 DEG C；Using cooling equipment instantaneous touch light diffusing sheet and light diffusing sheet is rolled, is utilized
Thermal expansion and contraction principle and crack propagation principle promote crackle to extend to depth direction, prepare for next procedure.
Rim charge separation: it is completely separated rim charge with light diffusing sheet ontology using rim charge separator；Wherein, rim charge separation dress
It is set in above transfer table and applying shearing splitting power to the crackle of rim charge is completely separated rim charge with light diffusing sheet ontology；
Rim charge transmission and particle: the two sides rim charge after separating with light diffusing sheet ontology is sent in Material disintegrator and is carried out immediately
Particle；
Wherein, the top position of workshop transfer table two sides is respectively equipped with hollow metal pipe, and side is straight linear metallic
Pipe, the other side are part or the turning formula metal tube across transfer table, are equipped with Material disintegrator, light in straight linear metallic pipe side
The rim charge of diffusion board width two sides is directly come into Material disintegrator by the guidance of metal tube to be blended.
The above-mentioned trimming recovery process for light diffusing sheet is simple to operation to rely on simple mechanical automation equipment
It completes, is participated in without artificial.It is blended in real time by the rim charge for cutting light diffusing sheet and avoids workshop inner edge material packing phenomenon, purified
Workshop condition and avoid light diffusing sheet pollute or different types of light diffusing sheet between occur mixing phenomenon, convenient for the rim charge later period
Recycling.
Preferably, in the trimming recovery process of the light diffusing sheet, the transversely equidistant chopping of the rim charge of rectangular strip, and
Rim charge after particle is collected into the collecting bag with identification rim charge raw material information mark.Rim charge is by equal in width on light diffusing sheet
It cuts, same to size, congener rim charge are of same size, and rim charge is transversely equidistantly cut to the rectangle particle of isometric surface area, make
Particle melts down fusion temperature indifference, and melting is more uniform, meanwhile, rectangle particle corner angle are unobvious, avoid piercing through collecting bag extension
The access times of collecting bag；Secondly, by directly being put by the particle being discharged in Material disintegrator with identification rim charge raw material information mark
It avoids misusing while making rim charge and light diffusing sheet that there is trackability in the collecting bag of knowledge.
Preferably, in the trimming recovery process of the light diffusing sheet, the cut lengths of rectangle rim charge are as close as possible to same type
The size of light diffusing sheet feed particles.Convenient for guaranteeing the melting synchronous with feed particles of broken rim charge, dissolve raw material molten slurry uniformly.
A kind of device being automatically separated for light diffusing sheet rim charge, comprising: U-shaped connecting rod 1 separates rectangle frame 2, the U
Shape connecting rod 1 is welded on the center of plane on separation rectangle frame 2, wherein two sides separation rectangle frame two side frames close to each other
Outer edge be overlapped with the parch crack of light diffusing sheet.
Preferably, the device being automatically separated for light diffusing sheet rim charge, at least symmetrically placed separation rectangle in two sides
The cross section of the side frame close to each other of frame 2 is placed in light diffusing sheet parch crack side for apex angle one end of triangle and triangle.Point
The side cross-sectional area for being used to separate rim charge and light diffusing sheet ontology 1 from rectangle frame 2 is triangle of the apex angle towards crackle side
Convenient for rim charge and light diffusing sheet are completely separated.
