Problems solved by technology
[0004] The above-mentioned on-line laminating device in the prior art uses rubber rollers to press the film. Since the plastic film is very soft, and the rubber roller itself has many micropores, its surface is not as smooth as the surface of the metal paper roller, and the film is pulled by the rubber roller. There will be unevenness on the surface after tightness, and many tiny bubbles will often appear on the surface of the paper after it is covered on the paper, which cannot meet the customer's appearance requirements for coated paper products

Embodiment Construction
[0011] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0012] see figure 2 , the present invention provides an online laminating device for a printing machine, comprising a side plate 40, a metal passing roller 50 for tensioning the film material 400 and for pressing the paper tape 300 and the film material 400 tightly against the film material 400. The rubber roller 60 on the metal paper passing roller 50, the metal passing paper roller 50 can be arranged on the side plate 40 along its own axial rotation and is located above the conveying path of the paper belt 300, and the rubber roller 60 can rotate along its own The rubber roller 60 is arranged under the conveying path of the paper belt 300 axially and rotatably, and the rubber roller 60 is arranged parallelly under the metal paper passing roller 50 so as to move up and down in translation. In this embodiment, the metal paper passing roller...

The invention provides an online film covering device for a printer. The online film covering device is characterized by comprising a side plate, a metal paper passing roller for tensioning a film material, and a rubber roller for compressing a paper belt and the film material on the metal paper passing roller; the metal paper passing roller can be rotatably arranged on the side plate along the own axial direction, and is positioned above the conveying way of the paper belt; and the rubber roller can be rotatably arranged below the conveying way of the paper belt along the own axial direction, and can be movably arranged in parallel below the metal paper passing roller in an up-to-down translation manner. Compared with the prior art, the online film covering device can greatly reduce the phenomenon that bubbles are generated on the surface of a film covering roll paper product when being used for covering a film on the paper.
Description
technical field [0001] The invention relates to the field of printing machinery, in particular to an online coating device used for printing machines that can reduce air bubbles in paper coatings. Background technique [0002] In web printing, it is often necessary to coat the printed paper. The surface of the coated paper is covered with a thin and transparent plastic film, which makes the surface of the paper smoother and brighter, and not only improves the gloss of the printed matter. And color fastness, prolonging the service life of the printed matter, at the same time, the plastic film also plays a protective role such as waterproof, anti-fouling, wear-resistant, folding-resistant, and chemical corrosion-resistant. [0003] see figure 1 , in the prior art, the on-line laminating device used for the printing machine is mainly composed of a side plate 10 and a metal paper roller 20 and a rubber roller 30 installed on the side plate, and the rubber roller 30 can move up ...
