The present invention relates to a cutting device for wrapping filim. Especially, a wrapping film made of vinyl chloride, polyethylene, aluminum foil, etc., which is wound on a spool, can be cut into a suitable size for use. It relates to a device that can.

In recent years, in the storage and delivery of products such as food and food, the tendency to use transparent or opaque film or foil in order to maintain the freshness for a long time and to enhance the design sense of the packaging has increased. And widely used in processing industries.

Looking at the state of use of such a conventional packaging film, first, as a simple use, by wrapping a suitable amount of film in a small diameter spool and placing it in a packaging container with a cutting blade, the film is taken out of the spore container for packaging. It is to be used by cutting with a cutting blade attached to the container itself. On the other hand, as a large-capacity one used in public or food processing businesses, a long-length film is wound around a large diameter spool and mounted on a separate electric drive cutting device to cut a predetermined length.

By the way, in the said simple packaging film, it is made to be wrapped by its own packaging container, and there exists a problem that it is difficult to take out when winding up a large quantity of film.

On the other hand, when a large-capacity packaging film is used, the film is usually cut to a predetermined length by holding a cylindrical packaging film by hand and cutting it with scissors or a knife, or by using an expensive electric drive cutting device as described above. Therefore, inconvenience in use and economic burden of the user had a big problem.

Accordingly, the present invention aims to solve the above-described problems, and according to the present invention, a cutting device for a packaging film having a simple structure, simple handling, and low cost is provided.

Next will be described in detail with reference to the accompanying drawings an embodiment of the present invention.

1 is a perspective view of a cutting device according to a first embodiment of the present invention, wherein reference numeral 1 denotes the entire framework of the cutting device, which is two side walls 1a and 1a 'and two side walls 1a and 1a. It consists of the partition wall 1b which divides between (') into predetermined space | intervals, and the front wall 1c and the bottom surface 1d which support the said side wall 1a (1a') and the partition wall 1b.

Between the side wall 1a and the partition wall 1b, three rollers, namely, the support rollers 2a and 2b for supporting the packaging film F of the cylinder and the tensioning roller 2c for adjusting the tension when the packaging film is pulled out, are provided. Are installed, which are fixed by the corresponding shaft number 4 via the shafts 3a, 3b and 3c protruding at each end as shown in the cross-sectional view of FIG. The distance between the opposing surfaces of the support rollers 2a and 2b is set smaller than the outer diameter of the spool S sandwiched in the film F of the cylinder, so that when the entire film F is almost consumed, the spool S It does not fall between these support rollers 2a and 2b.

The rollers 2a ', 2b' and 2c 'are fixed between the side wall 1a' and the partition wall 1b in the same structure as described above, and the lengths of the rollers 2a ', 2b' and 2c 'are fixed. Is shorter than the length of the rollers 2a, 2b, and 2c, so that films having different widths can be used together.

On the other hand, at the upper end of the front wall 1c, a cutting blade 5 for cutting the drawn film to a predetermined length is mounted.

In the above-described configuration, although the rollers 2a, 2b and 2c of the large size are attached in parallel with the rollers 2a ', 2b' and 2c 'of the small size, they can be configured separately. It may be. 3 is an enlarged perspective view of the main portion showing the second embodiment of the present invention, in this embodiment, to prevent the tip of the film remaining on the roller 2c side after the film is cut off between the rollers 2c and 2b. For this purpose, the check roller 2d is provided at the dotted line in Fig. 2, that is, on the roller 2c. In detail, the check roller 2d is connected near the end of the arm 6 via the shaft 3d, which is fixed integrally to the side wall 1a. This check roller 2d can be provided at one end or at both ends of the rollers 2c and 2c '.

4 is a longitudinal sectional view showing a third embodiment of the present invention. Since the cutting blade 5 shown in FIGS. 1 and 2 is exposed to the upper end of the front wall 1c, the blade may be damaged or the user's hand may be injured by a hard object. Therefore, in this embodiment, as a means for preventing such a problem in advance, as shown in FIG. At the same time as the cutting blade 5 is attached to the 7) side, the inclined surface 1e is bent and formed integrally with the front wall 1c on the side facing the cutting blade 5. Under such a configuration, not only the cutting edge damage and the user's injuries are reduced, but the tip of the film on the cutting device side after the cutting of the film extends over the inclined surface 1e, so that the check roller 2d is not employed. Even if the tip of the film does not slide down to the bottom of the device can be prevented.

According to the embodiments of the present invention as described above is provided with a cutting device for cheap packaging film is promoted the dissemination of packaging film showing a high hygiene effect is expected to contribute to long-term storage and freshness of food, and also drawings According to the constitution of the present invention as shown in the present invention, since it is possible to use films having different widths at the same time, the effect of reducing the waste of the film can also be achieved.
