Description

[Detailed Description of the Invention] The present invention relates to an adhesive tape cutting tool (tape cutter) used in a sealing device or the like.

There are two types of tape cutters known in the past: one with a fixed structure and one with a movable cutting blade. In both types, the adhesive tape is guided from a tape reel and passed through a guide roller. The material is pressed and adhered by a pressing roller, and then cut by a cutting blade.

At this time, since the tape is held only by the cutting blade, there is a drawback that if the tape is peeled off from the cutting blade, the tape must be pulled out from inside again.

In order to deal with these drawbacks, it has been proposed to provide a holding roller between the guide roller and the pressure roller.

However, although this type of tape can hold the tape, the tape sticks to the holding roller, making it difficult to feed the tape.
A new drawback arises: it does not move.

The present invention is an attempt to solve the above-mentioned drawbacks of a tape cutter with a fixed cutting blade in which a holding roller is provided between a guide roller and a suppression roller. The present invention is characterized in that a holding member having a shape is provided, and the tape can be held in point contact on the holding member.

Next, embodiments of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a frame formed by two side plates facing each other at a predetermined interval, and inside the frame 1, a suppressing member 2 is rotatably mounted at its left end on a shaft 3. ing.

A spring 4 is interposed between the frame 1 and the pressing member 2, and the spring 4 always urges the pressing member 2 to rotate counterclockwise about the shaft 3.

5 is a tape reel supported by the frame 1.

A guide roller 6 , a holding member 7 , and a suppressing roller 8 are arranged in this order from the left side on the lower surface of the suppressing member 2 , and a cutting blade 9 is fixed to the frame 1 at a position adjacent to the suppressing roller 8 . It is provided.

10 shows the adhesive tape in use.

The holding member 7 consists of a plate with upwardly curved ends (see Figures 2 and 3), and the tape 10 engages with the holding member 7 in point contact at its pointed end portions 7a and 7b at both ends. , is to be retained.

Note that it is desirable that the distance 11rL between the guide roller 6 and the tip portion 7b be as small as possible;
The tape 10 is held in such a manner as to hold the tape 10 therein, thereby ensuring that the tape is held securely and allowing smooth movement of the tape.

The use of this tape cutter is the same as the conventional one.

That is, the frame body 1 is positioned on the soil part of the bonding point.

Then, the back surface 2a of the pressing member 2 is pressed. This suppression causes the tape to move between the guide roller 6, the holding member 7, and the pressure roller 8.
move downward together with the suppressing member 2.

Since the pressure roller 8 is located at the lowest position among these three members, the pressure roller 8 comes into contact with the surface to be adhered, and at this time, the tape 10 is adhered between the pressure roller 8 and the surface to be adhered. It turns out.

While maintaining this state, when the frame body 1 is moved to the left, the tapes sequentially supplied from the reel 5 are supplied to the lower side of the pressure roller 8 via the guide roller 6 and the holding member 7, and are sequentially pasted. go.

When pasting is completed, the pressure on the pressing member 2 is released.

Then, the pressing member 2 is moved to −E by the restoring force of the spring 4.
Rotate in the direction.

At this time, the cutting blade 9 remains in its original position because it is fixed to the frame 1, but the guide roller 6, holding member 7,
Since the pressing roller 8 rotates upward together with the pressing member 2,
The tape 10 is pulled and cut by the cutting blade 9.

The above operation is the same as that of a conventional tape cutter with a fixed cutting blade.

During the above operation, the tape cutter of the present invention cuts the tape 10.
Since the tape is always held only by the pointed ends 7a and 7b of the holding member 7, the tape will not move unnecessarily after being cut, and the tape will move smoothly during the adhesion operation.

In the conventional type with a holding roller, the holding roller is provided on the adhesive side of the tape (the guide roller and the pressure roller are located on the non-adhesive side of the tape, and the tape is placed on the non-adhesive side of the tape, Because the tape is guided in an S-shape by However, as described above, the tape moves smoothly in the present invention, so the above-mentioned drawbacks can be overcome.

As described above, the present invention is directed to a tape cutter with a fixed cutting blade, and a holding member that holds the tape at the pointed end is provided between the guide roller and the pressure roller, thereby holding the tape. As a result, the tape can be held reliably and the movement of the tape will not be hindered, making it easier to use the tape cutter, and the practical effects of the present invention are remarkable. .
