Description
Technical field
The present invention relates to optical film processing technique field, in particular to a kind of wrap-up for reducing pipe coining, preparation method
And winding method.
Background technique
Science and technology is maked rapid progress development, and the appearance of many products changes people's lives habit, in response to the appearance of these products,
Identical material has different functions to meet various demands on different processing programs, by taking thin-film material as an example: in food packet
Fill the material of industry, it is desirable that, light-proofness good to oxygen barrier performance be strong, acid and alkali-resistance；In the material of building trade, weatherability it is strong,
Appearance abrasion-resistant；In electronics industry, reflection, prism, resists the functions such as dizzy, anti-pollution, anti-scratch ... at diffusion.But because material price is expensive,
Processing program is cumbersome or multiple functions cannot achieve on a kind of material, and each industry is developing complex technique, to save life
Cost is produced, process is simplified, meets product demand.But compound product is two or more material, by different processing journeys
Mutually bonding again after sequence, often material generates variation because after front process processing, improves in compound stage degree of difficulty.It solves again
Production determined after compound stage degree of difficulty topic, it is the important pass part for reducing cost that product, which winds tube bottom transfer,.The prior art is thin
In membrane material wrapup procedure, generally thin-film material is bonded in core mechanism using adhesive tape, with reference to attached drawing 1, what such method made
Thin-film material and material joint place generate step, in wrapup procedure, since joint place unit area pressure increases, be easy to cause
Thin-film material deformation generates impression.Meanwhile for needing to carry out compound thin-film material, the compound stage fitting glue also not
Solidification will be wound, and the tube bottom transfer generated in this way namely the rice up to a hundred of impression up to tens, this seriously affects product quality.
To solve the problems, such as that above-mentioned thin-film material generates impression, Chinese patent thin-film material rolling-up mechanism (patent No.:
201420025500.6) a kind of technical solution is disclosed, which makes thin-film material and volume concentric mechanism by joint adhesive band
Be bonded and form multi-stage stairs in joint place, and at the lowermost level step of joint adhesive band on the outside of be fitted at least one transition glue
Band, by the transition at the step of joint adhesive band of transition glue band, makes step after the thin-film material so made is connect with volume concentric mechanism
Gradually increase, drop slows down, to reduce step corner angle caused by thin-film material compared with the compressing of small area, avoids thin-film material
Deformation generates impression.Although the thin-film material deformation of above-mentioned 2014200255006 patent very good solution leads to the problem of impression,
But deficiency existing for above-mentioned patent is: the joint adhesive band and transition glue band of wrap-up need accurately to cooperate, wind-up operation
Complexity influences processing efficiency.
Therefore, market need it is a kind of reduction tube bottom transfer, reduce production cost, improve product quality reduce pipe coining
Wrap-up, preparation method and winding method.
Summary of the invention

Core, the lining form are PET lining form.
Compared with prior art, wrap-up beneficial effect of the invention is: first is that, the lining form of wrap-up is PET
Lining form can reduce the tube bottom transfer of production product, reduce production cost, improve production quality；Second is that the repeatable benefit of wrap-up
With saving production cost；Third is that wrap-up structure is simplified, it is easy to use.
According to the second aspect of the invention, the another technical solution that the present invention takes is as follows: a kind of to prepare first aspect
A kind of method of the wrap-up of reduction tube bottom coining, includes the following steps:
It is to be spooled to match with roll paper core axial width that step I uses banding machine that PED lining form cut into width
Lining form；
Step II is matched in lining form one end to be spooled pastes 3M double-sided adhesive at viscous joint location, and passes through 3M double-sided adhesive
By the docking Nian Jie with the cylinder core in the take-up roll for being set in banding machine of bonding head and lining form to be spooled；
Step III, is synchronized using banding machine and is cut and wound to lining form, the lining form thickness wound on cylinder core
The lining form for reaching 19~20mm and/or winding will be bonded the step pressing that head and cylinder core are formed；
Lining form is cut off and is formed docking step using Jie's knife by step IV, using tearing docking step of the adhesive tape by lining form
End is fixed with the lining form gluing wound.
According to the third aspect of the invention we, the another technical solution that the present invention takes is as follows: a kind of to use first aspect
