The bottom wall 23 has a guiding surface 231 which is concave in the shape of a circular arc, the guiding surface 231 facing the first end 25.

The reel 3 is rotatably pivoted to the base 2 in the recess 24 and adjacent to the first end 25 for the tape 1 to be wound. The take-up roller set 4 is rotatably pivotally connected to the base 2 in the recess 24 and spaced between the second end 26 and the reel 3, and includes a second portion perpendicular to the first direction D1 A first roller 41 extending in the direction D2 and extending through the sidewalls 22 and a second roller 42 disposed below the first roller 41 and extending in the second direction D2 and extending through the sidewalls 22 . The first roller 41 is adjacent to the discharge wall 21 and is rotatable in a first rotational direction R1. The second roller 42 is rotatable in a second rotational direction R2 opposite to the first rotational direction R1. The first roller 41 is configured to wrap the tape body 11 and move it toward the second end 26 . The second roller 42 is used to engage the first roller 41 to move the tape body 11 toward the second end 26 . Wherein, the second roller 42 is optional, and is only suitable for supporting the tape body 11 with the first roller 41 reinforcing guide, even if the second roller 42 is removed.

The guiding unit 5 includes a first guiding rod 51 which is disposed in the second direction D2 and is adjacent to the side wall 22 of the base 2 and is adjacent to the reel 3, and the second guiding unit 2 is disposed in the second direction D2. a side wall 22 adjacent to the second guide rod 52 of the deriving roller set 4, a third guide rod 53 extending along the side wall 22 of the base 2 in the second direction D2 and adjacent to the first guide rod 51, and a The second direction D2 is disposed on the side walls 22 of the base 2 and is located between the first roller 41 and the second roller 42 of the deriving roller set 4, a first spring 55, a second spring 56 a third spring 57 and a fourth spring 58. The distance between the first guiding rod 51 and the top surface of the base 2 is greater than the distance between the second guiding rod 52 and the top surface of the side walls 22. The first guiding rod 51 is used for the second portion of the tape body 11. The surface 112 is wound, and the second guiding rod 52 is used for winding the first surface 111 of the tape body 11. The distance between the third guiding rod 53 and the top surface of the base 2 is greater than the distance between the second guiding rod 52 and the top surface of the base 2. The third guiding rod 53 is used for the first surface 111 of the tape body 11. Winding. The fourth guiding rod 54 is used for winding the second surface 112 of the tape body 11 and guiding the tape body 11 to be discharged through the passage 211 of the discharging wall 21. The first spring 55 is sleeved on the first guiding rod 51 for winding the second surface 112 of the tape body 11 , and the second spring 56 is sleeved on the second guiding rod 52 for the tape body 11 . The first surface 111 is wound, and the third spring 57 is sleeved on the third guiding rod 53 for winding the first surface 111 of the tape body 11. The fourth spring 58 is sleeved on the fourth guiding rod 54. For this, the second face 112 of the tape body 11 is wound. The first to fourth springs 55, 56, 57, and 58 are all compression springs of the same specification, and the function thereof is to reduce the adhesive area of the tape body 11 by about 50%, so that the process of the tape body 11 traveling can be smoother. Therefore, it is possible to use even the first to fourth springs 55, 56, 57, 58 without the addition. It should be noted that the function of the third guiding rod 53 and the third spring 57 is to strengthen the guiding tape body 11 with the first guiding rod 51 and the first spring 55, so even if the third guiding rod 53 and the third spring are removed, 57 is still feasible.

The cutting mechanism 6 is disposed at the second end 26 of the base 2 and adjacent to the take-up roller set 4, and the cutting mechanism 6 is used for cutting the tape body 11 which is led out through the lead-out roller set 4, Actually two tools are placed above and below the channel 211. The operation panel 7 is a top surface of one of the side walls 22 of the base 2 for adjusting various settings of the cutting, such as length, frequency, and the like, and as a switch of the novel tape cutting device. Two baffles 8 are respectively disposed between opposite sides of the reel 3 and the side walls 22 of the base 2 to prevent the reel 3 from being displaced relative to the side walls 22 in the second direction D2 It is avoided that the tape 1 and the reel 3 are shaken in the second direction D2 during the operation, resulting in a decrease in the cutting precision and causing the tape 1 to be skewed during traveling without being smooth. In other embodiments, the number of the baffles 8 may also be one, which is disposed between one side of the reel 3 and the corresponding side wall 22, as well as preventing the reel 3 from being opposite to the corresponding side wall 22 The displacement in the two directions D2.

The following describes the use process of the new tape cutting device: first, before use, the user needs to peel off the release film 12 of the tape 1 from the tape body 11, and then follow the path of the tape body 11 along the path shown in FIG. The first spring 55, the third spring 57, the second spring 56, the first roller 41 and the fourth spring 58 of the lead roller group 4 are wound on the guide unit 5, and the operation panel 7 is operated to start the new tape cutting. The first roller 41 and the second roller 42 of the deriving roller group 4 are respectively intermittently rotated in the first rotation direction R1 and the second rotation direction R2 according to the set frequency, thereby driving the tape body 11 of the tape 1 along The path shown moves outwardly toward the passage 211 of the discharge wall 21. After the tape body 11 passes through the passage 211 for a predetermined length, the cutting mechanism 6 starts to operate the cutting tape body 11 to obtain a section. The tape body 11 used. In such a process, the bent portion 122 of the release film 12 is initially subjected to the force of the forward force and the weight of the tape by the adhesive portion 121 of the tape body 11 and is subjected to the tape body 11 The front side is downwardly driven, and finally contacts the circular guide surface 231 of the bottom wall 23 of the base 2, which faces the reel 3 for blocking the bending section 122, so that the bending section 122 will eventually follow substantially The route shown in Figure 2 extends toward the first end 25 of the base 2 from the recess 24. As described above, the present tape cutting device can automatically separate the release film 12 from the tape body 11 before cutting the tape 1.

In summary, the cutting device of the present type of tape 1 is combined with the roller group 4 by the arrangement of the guiding unit 5, so that the tape body 11 of the tape 1 is driven by the leading roller group 4 and can be separated from the release film 12 first. The cutting mechanism 6 is cut to achieve the effect of automatically separating the tape 1 from the release film 12 before being cut, so that the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
