Abstract
The utility model provides a diffusion piece divides strip material collecting device, includes upper portion open -ended material collecting box, the material collecting box lateral wall is opened has the feed inlet, is equipped with heating rod group in proper order and receives the material winding up roller from feeding hole end, wherein heating rod group contains the staggered arrangement's more than three heating rod, the heating rod of receiving material winding up roller and heating rod inter block is by motor drive, the direction of rotation homogeneous phase of all heating rods with and unanimous with minute billot direction of advance, receive the rolling direction of material winding up roller and the rolling opposite direction of diffusion piece masterbatch. Use the device, can obviously reduce the warpage because of the masterbatch rolling produces to only need short storage period.
Description
Technical field
This utility model relates to die-cutting device technical field, divides bar material collecting device especially with regard to diffusion sheet.
Background technology
Diffusion sheet has the effect of diffusing light, and diffusion sheet is normally on light guide plate, according to scattering of light principle, by being distributed on exiting surface of the uniform light penetrated in light guide plate.Most of diffusion sheet is all to be coated with astigmatic optics granule over the transparent substrate, to reach the purpose of light scattering.
The masterbatch of diffusion sheet is usually rolling packaging, because the plasticity principle of base material, so when masterbatch being carried out cross cutting process (especially with the masterbatch of internal diameter less tube core rolling), often warping phenomenon occurs after die-cut, warpage not only affects attractive in appearance, and extremely affect subsequent treatment, fly as blown by ion blower, be difficult to assembling etc..In actual production, in order to prevent the generation of warpage, some manufacturers use the astigmatism granule at diffusion sheet to add the mode such as particular matter and process diffusion sheet itself, but result also in the rising of relative cost, and it is the warpage produced for variations in temperature that this kind processes majority, and the best to the warping effect produced due to masterbatch rolling.For the warpage produced because of masterbatch rolling, veteran operator can select to place reverse for bundling material rolling, it is possible to play certain effect, but one is to need longer standing time (about one week), and two is the DeGrain that warpage eliminates.
Summary of the invention
For solving above-mentioned technical problem, this utility model provides a kind of diffusion sheet and divides bar material collecting device, while guaranteeing that reducing warpage in a large number occurs, and only needs shorter standing time.
The technical solution of the utility model is as follows: a kind of diffusion sheet divides bar material collecting device, rewinding box including upper opening, rewinding box sidewall has charging aperture, it is sequentially provided with heating rod group and rewinding winding up roller from feed inlet end, wherein heating rod group comprises the staggered heating rod of more than three, heating rod in rewinding winding up roller and heating rod group is driven by motor, the direction of rotation of all heating rods is the most identical and consistent with point billot direction of advance, and the rolling direction of rewinding winding up roller is in opposite direction with the rolling of diffusion sheet masterbatch.
Further, described heating rod group comprises five heating rods.
Further, the heating-up temperature of described heating rod group is less than the maximum operating temperature of diffusion sheet.
Use device described in the utility model, it is possible to significantly reduce the warpage produced because of masterbatch rolling, and only need shorter standing time.Below in conjunction with detailed description of the invention, technical scheme described in the utility model is further detailed.
Figure of description
Fig. 1 is this utility model structural representation.
Detailed description of the invention
As shown in Figure 1, rewinding box 1 including upper opening, rewinding box 1 sidewall has charging aperture 2, it is sequentially provided with heating rod group 3 and rewinding winding up roller 4 from charging aperture 2 end, wherein heating rod group 3 comprises the staggered heating rod of more than three, heating rod in rewinding winding up roller 4 and heating rod group 3 is driven by motor, and the direction of rotation of all heating rods is the most identical and consistent with point billot 6 direction of advance, and the rolling direction of rewinding winding up roller 4 is in opposite direction with the rolling of diffusion sheet masterbatch 5.
When masterbatch 5 is after slitting cutting, billot 6 is divided to enter rewinding box 1 by the charging aperture 2 on rewinding box, through heating rod group 3, choose whether a point billot 6 is heated and heating-up temperature according to masterbatch 5 speciality, a point billot 6 after heated moves on, and arrives rewinding winding up roller 4, opens the driving motor of rewinding winding up roller 4, make it in opposite direction with the rolling of masterbatch 5, to reach to reduce so that eliminating masterbatch rolling and the warpage that produces.
Special attention should be that, point billot using described in the utility model point of bar material collecting device should use as early as possible, through actual observation, after rewinding completes, between two to three days, using effect is optimal, too short meeting causes warpage eradicating efficacy the best, long, may cause the warpage in opposite direction with masterbatch rolling.
