Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] Such as Figure 1-2 As shown, a kind of combined doctor blade coating head structure of the present invention, comprises coating back roller 1, feeding roller 2, coating tank 8 and scraper device, coating back roller 1, feeding roller 2, coating Groove 8 and scraper device are all fixedly connected with coating machine frame, and these are prior art, do not go into detail here; Release paper film 3 comes out through coating back roll 1 again after feeding roller 2 coating. The coating back roller 1 is arranged tangentially directly above the feeding roller 2; the coating groove 8 is arranged directly below the feeding roller 2, and one side of the feeding roller 2 is in contact with the coating in the coating groove 8, and the scraper device One end is in contact with the coating back roller 1; the inner cavity of the coating tank 8 is provided with three inner...

The invention belongs to the technical field of release paper, and particularly relates to a combinational knife coating head structure. The combinational knife coating head structure comprises a coating back roller, a feeding roller, a coating groove and a knife device, wherein the coating back roller is arranged right above the feeding roller in a tangent manner; the coating groove is arranged right below the feeding roller; one side of the feeding roller is in contact with coating in the coating groove; one end of the knife device is in contact with the coating back roller; the inner cavity of the coating groove is partitioned into three inner cavities through a rear scraper board and a front scraper board; coating is arranged in the middle inner cavity; one side of feeding roller is immersed in the middle inner cavity; the top-end section of the rear scraper board is cone-shaped; the top end of the front scraper board is provided with an arc surface matched with the circular wall of the feeding roller; the arc surface and the circular wall of the feeding roller are arranged at intervals. When the combinational knife coating head structure is used, by scraping redundant coating on the feeding roller through the rear scraper board and limiting the coating thickness on the feeding roller through the front scraper board, the uniformity of the coating thickness is greatly ensured. The combinational knife coating head structure is simple, reasonable in setting, low in manufacturing cost and the like.
Description
technical field [0001] The invention relates to the technical field of release paper production, in particular to a combined scraper coating head structure. Background technique [0002] Release paper is also called release paper, anti-adhesive paper, silicone oil paper; it is a anti-adhesive paper that prevents prepreg from sticking and protects prepreg from contamination. The classification of release paper can be classified according to plastic release paper and non-plastic release paper. There is a plastic release paper, because the release agent has a certain permeability, if there is no certain barrier, the release agent will penetrate into the paper, resulting in poor curing and a large amount of release agent (too high cost), etc. factor. Therefore, it is necessary to do plastic coating on the paper (commonly known as lamination); it is the release paper produced by coating the release agent on the lamination surface after the base paper is laminated. It is diffic...
