Description

A knife unit for cutting box packaging tape and a box packaging tape cutting apparatus using the same. {A knife unit for cutting box packaging tape and a box packaging tape cutting apparatus using the same}

The present invention relates to a box tape cutting device, and more specifically, to a box tape cutting blade unit that can reduce the cutting resistance of the tape and enable sequential attachment and cutting of the box tape, and a box tape cutting device using the same. It's about.

In general, shopping is carried out in various types of spaces such as large supermarkets, home shopping, online shopping, and offline shopping, and in relation to these purchases, various products are packaged in packaging boxes of a certain size. The boxes used to package these products have their covers sealed with relatively wide box tape.

Republic of Korea Patent No. 10-1868272 discloses a tape cutting device, and Republic of Korea Patent No. 10-2246379 discloses a tape applicator. This tape cutting device and the cutting blade installed in the tape attacher have a structure in which sharp protrusions are formed to cut the box tape by cutting it.

When attaching and cutting tape to a packaging box using such a tape cutting device or attachment device, there is a problem in that the cut area of the tape is not uniform and unevenness occurs. The occurrence of these irregularities poses a problem in that the adhesive support at the end cannot be increased because the cut portion of the tape is not completely adhered.

Taking this into account, a tape cutter is posted in Republic of Korea Patent No. 10-0814244 (2008.03.10.), and a tape cutter is posted in Republic of Korea Patent Publication No. 10-2015-0044016 (2015.04.23). Registered Patent No. 10-2069009 (January 16, 2020) discloses a tape cutting device.

The conventional tape cutters described above have a structure in which the blade is rotated to cut the tape using the lifting displacement caused by the pressing force applied by the tape fixing table and the lifting members to the tape being cut.

These conventional tape cutters have a structure that cuts the tape by forming a cut or notch on the edge of the tape with a moving blade. Since the blade starts moving in a vertical state, the edge of the tape is smoothly cut or notched. There is a problem in that the cutting power of the tape is reduced because the formation of the tape is not performed smoothly.

In addition, the conventional tape cutter has a problem in that the lifting member is lowered by the tape during the process of attaching the tape, resulting in the tape being cut in an unwanted area.

Also, after the tape is attached by the tape cutter, the end of the tape supported by the tape cutter is not supported, so there is a problem in that the end of the tape is not aligned. For subsequent work, the user must align the end of the tape to the adhesive area. There is a problem that needs to be addressed.

In particular, when using a conventional tape cutter, the tape roll mounted on the tape support portion rotates in the opposite direction of the direction in which the tape is unwound due to the reaction force resulting from the removal of tension when the tape is cut. In this case, the end of the tape is connected to the tape mount or lift. There is a problem that the taping work cannot be performed smoothly because it is separated from the member.

Therefore, the load caused by cutting the tape 201 by the cutting blade 45 can be reduced.

When the tape 201 is cut as described above, the rotating member 41 is rotated to its initial state by the elastic support part 38 and the lifting member is raised.

When the tape is cut by the cutting blade 45, the tension applied to the tape 201 is removed, so the tape roll 200 supported on the tape roll mounting unit 21 is rotated in reverse by the reaction force. , reverse rotation is prevented in the cutter body 20 of the invention by a reverse rotation prevention unit 50. That is, the ratchet member 52 constituting the reverse rotation prevention portion 50 is in close contact with the outer peripheral surface of the tape roll 200, and thus reverse rotation of the tape roll 200 is prevented. The end of the tape cut in this process is supported by the tape support part 29, so that subsequent work can be performed without operator intervention.

As described above, the blade unit for cutting box packaging tape and the box packaging tape cutting device using the same according to the present invention can minimize the cutting load due to cutting the tape and prevent reverse rotation of the tape roll, thereby stably cutting the tape. Taping work for packaging is possible.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will understand that various modifications and other equivalent embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the attached registered claims.
