Abstract
The present invention discloses a plastic optical fiber sheet material drawing process and a device with multiple core mould heads, relates to a plastic optical guide fiber sheet material molding process and a device, and belongs to the technical field of plastic optical fiber manufacture. The present invention is characterized in that a plurality of core mould heads of an extruding machine are used for extruding a plurality of optical fiber core wires for synchronously coating and molding an optical fiber sheath by a plurality of cores; after being dried, optical fibers are arranged into sheets and dipped in an adhesive for combining sheet material; the sheet material is dried and directly coiled. The present invention has the advantages that optical fiber sheet material can be molded in one step; the present invention has few working procedures and reduces middle links and loss; consequently, the optical fiber sheet material has a smooth appearance and a high optical guide rate; simultaneously, the present invention largely enhances a production rate, reduces the cost, and largely reduces labor strength. The present invention has high economic and social benefits.
Description
A kind of multi-core mould drawing plastic optical fibre and sheet forming process and device belong to plastic optical fiber manufacturing process and equipment technical field.
Plastic optical fiber because have that flexibility is good, core diameter is thick, numerical aperture is big, with source-coupling efficiency height, handling ease, advantage such as easy to use, cheap, since sixties appearance, application constantly enlarges, and develops very fast.Domestic research plastic optical fiber starts from the seventies, but up to the present, most of producers still adopt single hole die head drawing plastic optical fibre, only has only a few producer to adopt four casement heads to draw.Its production efficiency is low, and the cost height.Plastic optical fiber is mainly used to make handicrafts such as flower, bird, worm, fish at present, at this moment also will be after the single bonding one-tenth sheet material of plastic optical fiber usefulness bonding agent, cut into different shape more as required, boundling is made fiber optic articles more at last, its operation is many, and in addition, plastic optical fiber is through repeatedly processing subject to damage, influence passes optical property, take a lot of work, time-consuming, labour intensity is also big.
Task of the present invention is development and has designed direct drawing plastic optical fibre and sheet forming process and device, extrude some fiber cores silks from the extruder multi-core mould, carry out the synchronous coating molding fibre sheath of multicore, oven dry, again that some optical fiber arrangements are in blocks, and impregnation is bonded to sheet material, and drying is directly batched sheet material again.
Technological process of the present invention is as follows:
The extruder multi-core mould is extruded the core silk, and---------------------row's silk---sheet material oven dry---batches sheet material to frictioning to impregnation to the synchronous coating molding fibre sheath of multicore again in the doubling gathering in the doubling arrangement in oven dry
Apparatus of the present invention are seen accompanying drawing 1:
1.-multi-core mould 2.-foreskin applicator 3.-drying oven 4.-row's roll dies
5.-broach 6.-and roll dies 7.-steeping vat 8.-doctor kiss coater
9.-jockey pulley 10.-sheet material drying oven 11.-sheet material batches device
The multi-core mould 1 that links to each other with extruder is n core hole, n is 8～72, be laterally multi-row staggered being arranged on the die head, the core silk of being extruded by multi-core mould applies cortex synchronously through cladding applicator 2, and the cladding applicator is provided with a corresponding n notch, put into cladding in the applicator, the core silk applies cortex synchronously by each notch respectively, enters drying oven 3 immediately, uses hot-air seasoning, otherwise can produce " turning white " phenomenon, influence passes optical property.Optical fiber after the oven dry is arranged in parallel optical fiber by row roll dies 4 and broach 5, the notch and the number of teeth on row's roll dies 4 and the broach 5, n is 8～72, by being provided with circular arc that radius is R and roll dies 6 it is drawn in flakes then, and the radian R on the roll dies 6 is if being not easy to optical fiber too greatly draws in, R is too little, then optical fiber is easily overlapping, usually R is 20～60mm, and the plastic optical fiber after closing up enters steeping vat 7, with n root plastic optical fiber bonding in flakes, by doctor kiss coater 8, scrape off unnecessary cementing agent,, further arrange silk again by jockey pulley 9, the arrangement sheet material, to prevent overlapping or distortion, sheet material after the moulding is entered sheet material drying oven 10, use hot-air seasoning, batch sheet material by batching device 11 at last, its sheet width can not waited by 5～50mm according to core number what and silk size directly, can directly make various handicrafts with this sheet material.
By the direct drawing plastic optical fibre sheet material of multi-core mould with arrange bonding after single hole or 4 casement heads are pulled out optical fiber again and compare in flakes: this technology and device can be with the sheet material one-shot formings, operation is few, cut down the number of intermediate links and loss, thereby optical fiber and sheet material flat appearance, light-conductive rate height, throughput rate improves and the cost reduction greatly simultaneously, labour intensity also reduces greatly, and the present invention has high economic benefit and social benefit.
Embodiment:
The plastic optical fiber and the sheet material that draw diameter phi=0.3mm with 36 core heads are example: the polystyrene material grain in the extruder is machined to about 200 ℃, by multi-core mould 1, its n=36, that is 36 core silks are extruded simultaneously, enter in the applicator that is provided with 36 notches, apply foreskin synchronously, enter 60～70 ℃ of hot blasts of drying oven 3 usefulness and dry the row's of entering roll dies 4 and broach 5 immediately, optical fiber is arranged in parallel, enter and roll dies 6, optical fiber is drawn in, and roll dies 6 is provided with the circular arc of radius R=30mm, silk is drawn in flakes, enter the steeping vat 7 that fills cementing agent, with the plastic optical fiber bonding in flakes, scrape off unnecessary cementing agent by doctor kiss coater 8, again by jockey pulley 9, further row's silk arrangement, to prevent that optical fiber overlapping or distortion is wherein arranged, the sheet material after the arrangement enters drying oven 10 again, use hot-air seasoning, by batching device 11, with the speed of 30 meters of per minutes sheet material is batched at last, its sheet width is about 12mm.With the sheet material of this method moulding, its work efficiency improved more than 10 times than originally, and the sheet material light-conductive rate reaches more than 70%.
