Description

Cutting machine of synthetic resin film {CUTTING MACHINE FOR PLASTIC FILM}

The present invention relates to a cutting machine for a synthetic resin film.

Since the resin film is thin and flexible depending on the type, it stretches well even with slight force, so when cutting the film into a rectangle, the resin film is laid out on a flat table and cut vertically with a cutter such as scissors or a sharp razor blade to the desired size. And then cut horizontally.

In addition, the raw film wound on the bobbin is cut in the longitudinal direction of a certain width using a simple rotary cutter, and then the cut film is cut back to the desired length horizontally with scissors or a sharp cutter.

The cutting of the conventional synthetic resin film used a small cutting machine that is operated by a movable knife plate up and down like a paper cutting machine to be cut by a fixed blade and a scissor action.

However, because the film is wound on the bobbin there is a problem that can not be cut in the longitudinal direction with small head.

Therefore, to cut a film into a rectangle, you must first cut it with scissors or a knife to a certain width, and then cut the cut film vertically.

In addition, two rotary cutters are installed at the left and right intervals on the rotating shaft to cut the bobbin wound in the bobbin between the rotary cutters and cut them vertically to a desired width. However, since only the rotary cutter does not have a horizontal cutting function, the vertically cut film should be cut horizontally with a certain length using small pieces, scissors or a knife.

As such, the conventional cutting machine has a one-way cutting function, and there is no cutting function of both directions of the Y-axis and the X-axis. Both stretched and deformed, it was difficult to cut to the exact size of the rectangle.

Therefore, there is not much loss of film during the cutting, the film surface is easily damaged, and the handling is difficult, which makes the work inconvenient and difficult to efficiently cut many films.

An object of the present invention is to provide a portable cutting machine having a bi-directional cutting function of the Y-axis and the X-axis that is cut into a rectangle of the desired width and length in the bobbin wound synthetic film.

Still another object of the present invention is to make it possible to use as a cutting machine that can cut a variety of synthetic resin fabrics and wallpapers, such as synthetic resin film at the same time in a desired exact size of the rectangle.

The present invention is provided with a pair of rollers for supplying the film to the cutting machine main body, and a pair of rollers for conveying while sandwiching the supplied film in a planar manner, the rotary cutter and the knife roller in the main body at any interval along the guide rail Horizontal cutting means for cutting the film vertically by cutting and vertically cutting the film, and rotating cutter and rack gear are installed on the guide rail coaxially and cut horizontally of the film width while moving left and right of the guide rail by the chain. It is coupled to the means by driving the roller by a drive mechanism installed on the side plate of the main body is to cut the horizontal and vertical rectangle while continuously moving the synthetic film supplied from the bobbin.

In more detail, the vertical cutting means and the horizontal cutting means of the present invention have a unit structure, respectively, which can be assembled or separated on the main body, and are simultaneously sandwiched by the supply means for assembling the main body and feeding the film wound on the bobbin horizontally. The film is first cut longitudinally by a plurality of rotary cutter mechanisms set to a predetermined width in a state of being horizontally sandwiched by the means.

Subsequently, the vertically cut film is horizontally cut by the rotation cutter of the horizontal cutting means moving along the guide rail by the chain in a state sandwiched in the plane.

At this time, the cutting width of the film is adjusted to the interval of the rotary cutter mechanism by a scale scale attached to one surface of the guide rail of the longitudinal cutting means.

The cutting length of the film can be numerically grasped by the counter, not shown, the distance traveled by the feed roller, and can be cut by measuring the length of the film to be directly cut.

Since the cutting machine of the present invention operates the vertical cutting means and the horizontal cutting means at the same time, one cutting machine has a bi-directional cutting function of the Y-axis and the X-axis so that the exact size of the film released from the bobbin in place without twisting or rubbing the film in place Rectangles can be cut more efficiently at once.

In addition, the cut film maintains the flatness of the fabric and is not partially stretched or deformed, so it can be cut to an exact specification.

In addition, since each mechanism constituting the cutting machine of the present invention can be assembled by division of labor production, the production cost is cheap and can be produced in large quantities more efficiently.

In addition, the cutting machine of the present invention is a lightweight portable, easy to transport to the work site, easy to handle, anyone can use it easily without any special technology. In addition, since the rotary cutter mechanism is located inside the cutting machine, there is no risk of getting injured without touching the hand, so it can be used more safely.

If any part breaks down during use, only the unit of the part can be removed and replaced or repaired.

The cutting machine of the present invention has no failure point other than wear of the rotary cutter, and the blade of the rotary cutter may be used by grinding or replacing.

The cutting machine of the present invention can be usefully used for cutting not only the ultraviolet coating film but also various kinds of films, paper wallpapers, and the like, and particularly for cutting fabrics wound on bobbins.
