Description
Technical field
The utility model relates to a kind of at the production process of film or the vacuum flattening device in the reprocessing process at film.
Background technology
The film of the film of indication general reference thickness below 30 μ in the utility model, it comprises plastic sheeting or metallic film (take the metal platinum film as common).
in the production process of film, there are membrane and wrapup procedure, due to after film is stretched to certain thickness, the dual-side of film is easy to wrinkling, if film is not flattened, during rolling, the rolling rear film will produce fold, this does not conform to the symbol product requirement, therefore, in the production process of film, can be in the moving process of film, install some leveling rollers additional, leveling roller commonly used is the screw thread leveling roller, be distributed with the screw thread that tilts to both sides respectively from the mediad bilateral symmetry on the surface of screw thread leveling roller, when film contacts its flat of thread, the screw thread that flattens on roll surface with screw thread produces friction, the screw thread that tilts with base material to the two ends expansion of screw thread leveling roller, film is flattened.This screw thread leveling roller is to rely on film and the screw thread that flattens on roll surface with screw thread to produce friction, and film is flattened, still, in the production process of film, what often the screw thread on film and screw thread flattening roll surface can not be pressed is too tight, otherwise, will cause the transition of film longitudinal stretching.Therefore, to flattening lower than the film below 30 μ, it flattens effect is not very desirable with the screw thread leveling roller.
In the reprocessing process of film, generally all need through unreeling, after film surface processes (as coating, stamp or plastic uptake etc.), rear processing (as drying), carry out again rolling, in these processes, all need film is flattened effectively, otherwise, fold can be produced in each stage, in case film produces fold, the product of producing will become substandard products or waste product.In the reprocessing process of film, the most frequently used flattening method is to use the screw thread leveling roller, the screw thread leveling roller is the screw thread that is distributed with from the mediad bilateral symmetry on the surface of screw thread leveling roller to tilt to both sides respectively, when film contacts its flat of thread, the screw thread that flattens on roll surface with screw thread produces friction, the screw thread that tilts to the two ends expansion of screw thread leveling roller, is flattened film base material.As previously mentioned, this screw thread leveling roller is to rely on film and the screw thread that flattens on roll surface with screw thread to produce friction, and film is flattened, but in the production process of film, often film and screw thread flatten too tight that screw thread on roll surface can not press, otherwise, will cause the transition of film longitudinal stretching.Therefore, to flattening lower than the film below 30 μ, it flattens effect is not very desirable with the screw thread leveling roller.
Someone has proposed some schemes, and wish solves the flattening problem of film in operational process, but the flattening effect of its scheme neither be very desirable.Thin film cladding device as disclosed in Chinese patent CN102582209 and coating film vacuum flattening method, wherein, disclosed film vacuum flattening method utilization flattens inner N the cavity that arranges of case and is connected to form negative pressure through the admission port of corresponding solenoid control and negative-pressure air fan, N=1,2 ... n; This flattening case adsorption pore produces adsorption affinity to the band shape that moves the along its length coating film of pressing close on it, making the coating film be adjacent to the angled protrusions muscle that flattens on case moves, and be subject to the guiding of raised ribs and flatten to coating thin-film width direction two outsides, coating film fold is flattened.Not only there are complex structure in this flattening device and method, and it is in practice, and the existence owing to flattening the angled protrusions muscle on the case bottom surface also can make film produce the secondary fold in the process that flattens film.
The utility model content
In order to overcome the problems referred to above, the utility model provides a kind of film in moving process to society, can make film to flattening perpendicular to the both sides of moving direction, bandwagon effect good and to film without the film vacuum flattening device that injures.
The utility model provides a kind of vacuum flattening device, comprise the negative pressure source device that is connected with negative pressure source and the adsorption piece that is provided with many adsorption holes, described adsorption piece moves with respect to described negative pressure source device, and is communicated with the external world by the part adsorption hole on the selective control adsorption piece of negative pressure source device.
