Because the process variables are unstable, there are some problems of uneven distribution of tension in the finished film; if so, when the film is cut later 'The film after cutting often shows curling or curling, etc., which affects the progress of the cutting process and the subsequent processing of the film after cutting. Furthermore, even if the tension distribution of the film product itself is uniform, the current film cutting mechanism has the following problems in performing the film cutting operation; that is, the film to be cut is often caused by the cutter ( Such as: the cutting edge of the cutting force Μ ^ ring 'will still cause curling or curling (four) phenomenon, so that for the after-hand 溥 _ application process, will undoubtedly cause the processing difficulties, and then The non-performing rate of the finished product is increased. In view of this, Zaomu ^Ming people have been carefully researched and developed for many years in the development and manufacturing experience of related industries, and finally have the invention. 20 [Summary of the Invention] The purpose of the ruling is to provide a kind of mechanism, which can make the item material material have no obvious curls, 'because the thin sheets are higher in the subsequent stages. < $日' will be smoother, and the final application product yield is also 4 13.01428. In order to achieve the above purpose, the household of the present invention is used to cut a film, and the _ Μ, the kind of cutting mechanism has a seat Body, w-cutting device, the cutting device is provided with a cutting piece and a steam red, which can be placed by the cylinder, and along the carrier film of the path_ _System 2 = Previous k^, sent and has a front clamp and a rear clamp, the hai-clip firmware is sub-readable as the film, so that the film between the two clamps maintains a predetermined tension The cutting member is directed along the cutting path toward the film axis between the two clamp members and cuts the film. In other words, the cutting mechanism of the present invention has a predetermined tension by fixing the film before and after the cutting end, so that the film after cutting and the film to be cut are less likely to curl. Further, the subsequent transfer operation of the film to be cut, and the subsequent processing procedures of the cut film are smoother, and the final film application product yield is also 15 13⁄4 [Embodiment] First to fifth figures According to a cutting mechanism 丨00 of a preferred embodiment of the present invention, the cutting mechanism 100 includes a cutting device 1 , a guiding device 30 and a carrier film 2 device 20, in the embodiment, the cutting device The device 1 is mounted on a machine together with the film-carrying device 2 (not shown), the film-carrying device 2 can be any mechanism capable of transporting the film 99 along a film feeding path D1 (due to The transfer of the film is not the focus of the present invention, and the details of the film feeding can be referred to the inventor's application No. 95147741, the film feeding machine, and the case. The cutting mechanism 100 of the embodiment of the 1301428 is described below. : The guiding device 30 has A stand 31 is provided with a guide rail 32, wherein the guide 32 is axially oriented parallel to the direction of the film feed path di. • The cutting device 10 has a body 14 having everything on the body 14. • 5 broken pieces (in this embodiment, an electric hot cutting line U), a cylinder 12, and a servo motor π; the cutting piece 11 is erected on the straight frame 15 and fixed to a horizontal line via the straight frame 15 The frame 16 is connected to the cylinder 12 and is reciprocally movable along the cutting path D2 perpendicular to the film feeding path D1 by the steamer cylinder 12, and the length of the electric heat cutting line 11 is greater than the length of the film 99. The film 10 is hot-cut by the film 99, and the cutting device 10 can be driven along the guide rail 32 of the guiding device 30 through the driving of the servo motor 13, that is, precisely displaced along the parallel film feeding path D1. The film-carrying device 20 is located on the side of the cutting device 1 and has a front clamping member 21 and a rear clamping member 22. The front and rear clamping members 21 and 22 are all on the 15th. , the corresponding two clamping cylinders (211) (212) (221) (222) stupid constitute 'their permeable control system (not shown) The operation is to clamp or loosen the opposite ends of the film 99 parallel to the film feeding path D1. In addition, in the present embodiment, the front clamping member 21 can be subjected to the moving device of the film carrying device 20.
