Description

The present invention relates to a tape cutter that can easily peel off the release paper of a double-sided tape.

Double-sided tapes are widely used in everyday life as well as in industrial and commercial fields. However, peeling off the release paper by hand can be time-consuming and laborious, and improvements in convenience are needed.

Although many tape cutters for double-sided tapes have been developed in the past, no cutter for double-sided tapes has been developed that creates a claw at the cutting point of the double-sided tape for peeling off the release paper.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following, the same reference numerals in different drawings indicate parts having the same functions, and duplicated explanations in each drawing will be omitted as appropriate.

In the present invention, the "double-sided tape" refers to a tape having adhesive surfaces on both sides, one of which has a release paper attached thereto.

Fig. 1 is an external view of the double-sided tape cutter as seen from the right side of the tape cutting section 1b, and Fig. 2 is an external view as seen from the left side of the tape cutting section 1b. The double-sided tape cutter is made up of the parts and structure shown in Figs. 1 to 7.

FIG. 1 shows an external view of a tape cutter for double-sided tape according to an embodiment of the present invention. The cutter base main body 1 is roughly divided into a tape placement section 1a at the rear and a tape cutting section 1b at the front. The tape cutting section 1b is provided with a guide support section 3b and a guide receiving section 3c for mounting a guide member 3a for slidably supporting the cutter section 2. A groove for clamping one end of the guide member 3a is provided at the top of the guide support section 3b, and the guide member 3a is supported rotatably by a bolt 1d and a nut 1e. A groove for clamping and holding the other end of the guide member 3a is provided at the top of the guide receiving section 3c, and holds the guide member when cutting the tape. The groove may be shaped so that the opening is slightly larger than the bottom to facilitate the insertion of the guide member 3a.

4 shows a view from below of the cutter section 2. Inside the cutter section 2, there is a perforated rotary blade 6 for cutting only the tape portion, and a rotary blade 7 for cutting the entire double-sided tape including the tape portion and the release paper, with a spacer 8 sandwiched between the two blades to separate them from each other, and the two blades 6, 7 and the spacer 8 are rotatably fixed by bolts 2a and nuts 2b.

The tape shaft 4 is fixed to the cutter table main body 1 through the core of the cylindrically wound double-sided tape body 11. Fig. 5B is a cross-sectional view of Fig. 5A taken along the line A-A, as viewed from the back of the double-sided tape cutter. A tape shaft fixing groove 1c for passing the tape shaft 4 is provided on the inside of the cutter table 1. Fig. 6 is an overall view of the tape shaft 4. Fixing protrusions 4a are provided on both ends of the tape shaft 4, and these protrusions are fitted into the tape shaft fixing groove 1c to fix the tape shaft 4. The tape shaft 4 is inserted from the top of the cutter table main body 1, and then moved to the tape cutting section 1b side and fixed to the cutter table 1. The tape shaft fixing groove 1c may be inclined from the top to the bottom so as to approach the tape cutting section 1b side.

The tension rod 5 is a part to prevent the double-sided tape from sagging. The tape pulled out from the tape shaft passes under the first tension rod on the side closer to the tape placement section 1a, and then passes over the second tension rod on the side closer to the tape cutting section 1b. This prevents the tape from sagging until it reaches the cutting section.

The tension rod 5 should be Teflon-coated to prevent the tape from sticking to it. The rod itself may be designed to rotate so that the tape can be pulled out smoothly.

7 is a top view of the tape cutting section 1b. The groove 9 for the perforated rotary blade and the groove 10 for the cutter blade are provided on the upper surface of the tape cutting section 1b so that the double-sided tape can be cut in a straight line when the cutter section 2 is moved and the blade can firmly bite into the tape. The groove 9 for the perforated rotary blade is located at a position farther away from the tape placement section 1a than the groove 10 for the cutter blade. The groove 9 for the perforated rotary blade is fitted with the perforated rotary blade 6, and the groove 10 for the rotary blade is fitted with the cutter blade 7 as a cutter blade, to form perforations in the double-sided tape and cut the double-sided tape, respectively. The cutter blade does not necessarily have to rotate, and may be a knife-like blade.

The tape portion of the double-sided tape that was cut off by the two blades remains on the surface between the perforated rotary blade groove 9 and the cutter blade groove 10 of the tape cutting portion 1b. Therefore, this portion needs to be made rough so that the tape portion can be easily attached and peeled off.

The method of using this tape cutter is shown in Figures 8A to 8D. First, the double-sided tape body 11 wound into a cylindrical shape and threaded on the tape shaft 4 is set on the cutter stand body 1, and the double-sided tape peeled off from the double-sided tape body 11 is passed up and down the tension rod 5 to the tape cutting section 1b. When pulling out the double-sided tape, the guide member is lifted up so that the cutter section 2 does not get in the way (Figure 8A).

After the double-sided tape is pulled out and attached to the tape cutting section 1b, the cutter section 2 is lowered to a position where it contacts the cutting section 1b, and the double-sided tape is fitted into the gap between the cutter section 2 and the tape cutting section 1b (FIG. 8B).Then, the cutter section is moved along the guide member to form a cutting line and perforations in the pulled out double-sided tape.

After the cutting line and perforations are formed in the double-sided tape, the cutter section 2 is lifted (FIG. 8C). At the end of the double-sided tape on the tape cutting section 1b, perforations and a cutting line are formed to form a tape peeling mark (the part of the cut end surface of the double-sided tape where there is no double-sided tape with an adhesive side and only the release paper is exposed).

The double-sided tape of the part to be cut is peeled off from the cut portion 1b from the side to be cut to the part with the mark (perforation), and the tape is pulled toward the user, so that only the tape part is cut at the part with the mark and remains attached to the cut portion 1b (FIG. 8D). The double-sided tape thus cut off is as shown in FIG. 9A, which is seen from above, and FIG. 9B, which is seen from the side. At the end surface of the cut off double-sided tape, the tape part 11b remains at the cut portion 1b from the end surface of the double-sided tape to the part with the mark (perforation), so that the tape part of this part is cut off in the cut off double-sided tape. Then, a claw part 11c without the tape part 11b is formed on the release paper 11a from the end of the release paper 11a of the cut off double-sided tape to the part with the mark. When the cut off double-sided tape is applied to a necessary place, the part where only the release paper remains is not applied, so this part becomes the claw part 11c and the release paper can be peeled off.

By adjusting the diameter of the tape shaft, the present invention can be applied to double-sided tapes of various sizes, and because it has a certain width, it is also possible to store multiple rolls of double-sided tape in a single tape cutter.

The present invention makes it easier to remove double-sided tape by creating a claw on the release paper. In addition, it is possible to store various sizes and numbers of double-sided tapes, which is expected to reduce storage space. Furthermore, the blade that cuts the tape is mostly covered inside the cutter case, and it is inserted into the groove when cutting, so the work can be done safely.
