Description

Cutting device for roll tape

Embodiments disclosed herein relate to a cutting device for a roll tape, and more particularly, to a cutting device for a roll tape capable of performing taping and cutting the tape through a tape unwound from a cylindrical bobbin.

In general, in order to pack a box in which goods are stored, the opening and closing part of the box is closed and then the opening and closing part is sealed using an adhesive tape. As such, roll tape is most commonly used to seal the opening and closing part of the box.

In other words, roll tape is a type of adhesive tape wound around the outer circumference of a cylindrical bobbin, and is widely used for packaging because it is easy to use continuously. It is a cutting device for roll tape for box packaging that is used to make it easy and convenient.

Conventional roll tape cutting fixtures form a holder at the rear of the main body so that the bobbin of the roll tape can be fitted to the holder, and the tape cover covering the roll tape inserted into the holder is rotatably coupled to the main body on the upper part of the main body, Inside, a guide roller for guiding the roll tape, a pressure roller for pressing the tape when attaching the roll tape to the box are installed, and a cutting blade for cutting the attached roll tape is installed on the front of the main body.

When packaging a box using the conventional roll tape cutting device for box packaging as described above, the opening and closing part of the box is first covered and closed, and then the end of the roll tape inserted into the holder of the roll tape cutting machine for box packaging is attached to the side of the box.

In this state, when the body of the cutting machine is pulled and moved, the roll tape inserted into the holder rotates and the tape is continuously released. Since this is done at the same time, it is possible to quickly seal the opening and closing part of the box.

And after the box sealing is completed, if the surface of the roll tape used for attaching the box is pressed using the cutting blade installed on the front of the main body of the cutting machine, the roll tape is cut and the box packaging is completed.

By the way, the conventional cutting device as described above has a configuration in which the tape and the circular pressure roller are in point contact on the cross section, so that the tape flows arbitrarily while being separated from the pressure roller after taping.

Accordingly, the conventional cutting device is inconvenient to perform taping while moving the main body after holding and adhering the front end of the tape by hand during taping.

In addition, since the conventional cutting device has a configuration in which the tape flows arbitrarily without adhering to the pressure roller, the tape may deviate from side to side during taping, and furthermore, there is a problem that the tape may separate from the cutter.
