The method of fixed arranging single sheet of paper in sequence continuously through corona treatment
Technical field
The present invention relates to print, packing, paper product industries carry out the method for corona treatment to the surface of plane sheet-fed, especially under the continuous feed status in plane to carry out the method for corona treatment by the sheet-fed surface of permanent order arrangement mode.
Background technology
At present, the technology that corona treatment plant is carried out on known surface to individual flaky material of plane is individual flaky material to be sent into several between the upper and lower discharge electrode that resistance shelves dielectric material is housed by transport, be close to bottom discharge electrode medium below the flaky material, leave certain air gap between another side and top discharge electrode extreme, make the two poles of the earth of discharge to produce the surface that hepatic corona goes to impact flaky material and reach the purpose that changes the material surface performance by the air gap.This device is effective for not needing to carry out surface treatment by the flat and hard flaky material that fixed form is arranged, but the stationary arrangement displacement in proper order that corona treatment will cause its and discharge electrode to touch causing paper because of natural out-of-flatness of sheet-fed and paper sheet thickness different is carried out on the surface of carrying continuously the sheet-fed of arranging by permanent order on platform, also can cause discharge electrode inhomogeneous or puncture, thereby influence the corona effects of paper and the normal operation of corona equipment the corona of paper.Just because of the sheet-fed that does not have can be on platform to carry permanent order to arrange continuously to need in known technology carries out the device of corona treatment, thus many on planar working table, need to the sheet-fed that continuous conveying permanent order is arranged print, therefore the technology of coating, glazing, multiple film just can't adopt the mode of corona treatment to change the surface property of paper.
Summary of the invention
In order to realize the sheet-fed surface that continuous conveying is arranged by permanent order is carried out the purpose of corona treatment at planar working table, the technical method that the present invention takes is: plane conveyer belt upper and lower be provided with several to degree of tightness by the self-regulating letterweight plain-barreled roll of spring tube, be provided with the corona discharge utmost point that can horizontally slip and locate adjustment between the neutral gear of roller and roller according to the fabric width of paper.When paper passes through letterweight plain-barreled roll tube, can only be close to conveyer belt by discharge electrode, and can not contact with discharge electrode.And owing to discharge electrode can slide and locate, so the working width of discharge electrode can be adjusted with the fabric width of paper within the specific limits, thus this method can reach that discharge electrode only produces corona on the paper of sheet-fed and paper can be constantly by the purpose of stationary arrangement sequentially-fed and motion.The beneficial effect that it produces is that the capillary application demand that feasible method by corona treatment changes sheet-fed is accomplished, thereby improves the quality of printing packaging technologies such as printing, glazing, coating, multiple film, reduces production costs.
Purpose of the present invention, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
