Description

Technical Field

[0001] The utility model relates to the technical field of partial film lamination of roll paper connection lines, in particular to an intermittent paper-plastic laminating device. Background Art

[0002] Lamination is a common post-printing process. A layer of film is applied to the paper surface through a laminating device to protect the paper and improve the glossiness. Traditional label lamination covers the entire label surface with film. The amount of film used must be consistent with the total length of the material.

[0003] For partial lamination processes, such as those found on medical booklet labels, only a portion of the label is laminated. Traditional laminating devices do not have this capability. If traditional laminating devices are used to achieve partial lamination of a product, the product must be cut after lamination, or the film must be cut in advance and the lamination angle and position precisely controlled. This operation is cumbersome, production is difficult, and further improvement in production efficiency is difficult. Utility Model Content

[0004] The disclosed embodiments relate to an intermittent paper-plastic laminating device to solve the problem of partial lamination, such as the partial lamination on medical book labels, where only part of the label is laminated. Conventional laminating devices do not have the function of partial lamination. If conventional laminating devices are used to achieve partial lamination of products, it is necessary to cut the film after lamination, or cut the film in advance and precisely control the lamination angle and position. The operation is cumbersome, the production is difficult, and the production efficiency is difficult to further improve.

[0008] In at least some embodiments, a fixed film cutting plate is fixedly connected to the lower edge of the outlet of the lifting film outlet frame, and a cutting edge is formed on the right edge of the fixed film cutting plate by bending and grinding.

[0009] In at least some embodiments, the cutting knife holder is internally slidably connected to a lifting cutter, the lifting cutter is perpendicular to the upper surface of the laminating table, the upper edge of the lifting cutter is provided with a cutter connecting plate, and the right surface of the cutting knife holder is fixedly connected to a feed push cylinder, and the lower end of the push rod of the feed push cylinder is fixedly connected to the cutter connecting plate.

[0010] In at least some embodiments, the two pressing rollers are arranged longitudinally, the rear ends of the pressing rollers are fixedly connected with pressing linkage gears, the pressing linkage gears at the rear ends of the two pressing rollers are meshed and connected, and the front end of the support shaft of the upper pressing roller is fixedly connected to the rotating shaft of the pressing drive component through a coupling.

[0011] The utility model provides an intermittent paper-plastic laminating device, which has the following beneficial effects:

[0012] The paper-plastic laminating device in the present invention is provided with a pre-cutting function of the film. When performing intermittent partial laminating operations, the electric eye sensor can identify the pre-made reserved electric eye in the film and trigger the cutter to cut the film, thereby cutting off the film and realizing the intermittent film feeding function. At the same time, the paper located above the laminating table continues to be transported to the right at a uniform speed to form a laminating space, thereby realizing partial lamination of the product. Compared with the traditional coating device, for the intermittent laminating process, there is no need to pre-cut the film.
