The present invention relates to an adhesive tape cutting device that can cut the adhesive tape for product packaging to a certain length.

Packaging of goods requires a relatively large amount of adhesive tape.

And so far, such adhesive tapes are mainly used in roll tapes or adhesive tape pieces of adhesive bases.

However, in the use of the adhesive tape as described above, the electronic roll tape must pull the tape wound on the roll tape to a predetermined length every time, and cut the tape by pressing the pulled tape to the cutting knife attached to the roll. Not only could not cut a large amount of adhesive tape, but also the cut length was not constant, so the appearance of the packaging was unsatisfactory.The latter tape piece of adhesive base had to be peeled off one by one. With the hassle of using it, it had a problem that it takes a lot of time to pack.

In addition, in recent years, an electric cutting device that rotates the thermal adhesive tape by using the electric force has been proposed, but since the structure is complicated and large, the price is not only expensive but also frequently broken and inconvenient to use. It is

It is an object of the present invention to provide an adhesive tape cutting device capable of cutting and using a large amount of adhesive tape at a predetermined depth in one simple operation in view of the conventional problems as described above.

In more detail, the present invention is a single tape operation tape cutting device having a mechanism for cutting a certain length of cutting tape pieces at a time by a large amount, and when the adhesive tape is cut so that it must be cut An object of the present invention is to provide an adhesive tape cutting device having a mechanism for securely holding a tape.

In addition, the present invention has another object to provide an adhesive tape cutting device having a structural feature that makes it easier and faster to remove the cut tape fragments with a finger.

22 is a partially exploded perspective view showing another embodiment of the operation method by the rotary knob 6 of the present invention, the device is a gear group using the idle gear (7), ratchet gear (9) and the drive lever (90) It is configured to operate the ratchet gear (9) by the operation of the drive lever 90 to rotate the rotating roller (10) by interlocking the main gear (4) in contact with it.

The driving lever 90 is operated by the reciprocating motion of the driving lever 90 in the lever groove 78, that is, when the upper and lower presses the cutting device, and the spring is returned to its original position by the restoring force. .

Next, the effect of the present invention will be described.

First, a plurality of ordinary roll tapes 50 are selectively inserted into the rail roller 40, and then the end of the tape 51 is passed between the rotation roller 10 and the pressure roller 20 and the end is rotated again. It is used to guide and guide between the roller (10) and the cutting roller (30).

Subsequently, when the rotary knob 6 is rotated in the clockwise direction, the main gear 4 and the rotating roller 10 arranged on the coaxial 11 are rotated in the same manner, and at this time, the rotating roller 10 is moved by the rotation of the rotating roller 10. The presser roller 20 press-contacted to the contact surface 15 of the rotational roller 10 has a slight flow toward the opposite side of the rotational roller 10 while the tangy piece 27 elastically responds to the pressure according to the contact. ), The tape 51 of the roll tape 50 wound on the roll tape 50 is reliably conveyed. At the same time, as the driven gear 5 in contact with the main gear 4 rotates, the cutting roller 30 constructed on the coaxial 31 is rotated, and each cutting knife 32 thereof rotates the rotating roller ( The tape piece 52 is cut by cutting the tape 51 while the tape 32 is exactly inserted into each groove 14 of the rotating roller 10 while being exactly matched and inserted into each groove 14 of the rotating roller 10. Adhesion to the contact surface 15 is to wait for use.

In addition, as shown in FIGS. 17A and 17B, the protrusion of the rotational roller 10 which makes direct contact therewith by minimizing the length l of the rotational radius of the cutting knife 32 of the cutting roller 30 to a minimum. Since the length (l ') of the turning radius of (13) is relatively long, the size of the pupil 12 formed between the protrusions 13 is formed to the maximum size, thereby adhering to the contact surface 15. The tape piece 52 can be quickly and easily peeled off with a finger, thereby enabling efficient packaging.

Further, since the protrusions of the rotational roller of the present invention can be alternately formed into half-sections or detachables as described above, the lengths of the tapes to be cut can be simultaneously selected as long or short as needed. 60) can be used to cut to any length if you want to use longer.

Therefore, the present invention is to insert a plurality of roll tapes 50 at the same time to the roller 40 to cut a certain length or a long or short tape at the same time or any length, so that efficient cutting can be performed, and The tape 51 passing through the squeegee roller 20 securely holds the tape 51 when the contact surface 15 of the rotation roller 10 is cut by the cutting knife 32 to perform a perfect cutting operation. It can be.

In addition, the present invention has a very practical effect because the structure is simple, not only easy to use and operate, but also provide a low failure rate and low cost.

Various modifications as described above may provide the same effect as the implementation according to the present invention, and other various embodiments may be proposed by those skilled in the art, but all of these It is to be understood that the present invention is intended to be embodied as the scope of the present invention, and such embodiments and embodiments are naturally and reasonably included within the scope of the contribution of the present invention by the present technology.
