Description

  The present invention relates to a tape cutter capable of forming a folded portion at a cut end of an adhesive tape when the adhesive tape is pulled out and cut.

  As a tape cutter capable of forming a folded portion at the end portion of the tape, one as described in Patent Document 1 has been proposed. In other words, as a configuration in which the adhesive surfaces are bonded together by bending the tip of the tape, when the working rod with the cutting blade attached pulls out the adhesive tape, the adhesive tape is pulled out to the cutting position and cut by the cutting operation. The hook is rotated by a spring to the roller on the tape side, to which the adhesive tape is attached, and a folded portion is formed at the end of the tape. However, the adhesive tape is pulled out, and the working rod with the blade attached is pulled out to the cutting position. However, the adhesive tape may be cut unexpectedly in the middle of pulling out, and depending on the quality of the adhesive tape, there is a thin adhesive paste. The sliding blade may not rotate to the cutting position on the blade.

  In the case of Patent Document 2, two tape adhesive parts, a fixed adhesive part and a swinging plate that becomes a movable adhesive part, are provided and fixed between the adhesive tape mounted on the base and the tape cutter blade installed on the same base. With the adhesive tape pulled out from the adhesive tape attached to the movable adhesive part urged by the adhesive part, pull it out to the cutting blade, and after the cut, the movable adhesive part of the adhesive tape stretched between the two adhesive parts Is rotated to the original fixed adhesive portion to form a tape ring with the adhesive surface of the adhesive tape inside.

  The adhesive tape pulled out in this way is affixed onto the rocking plate, and the tape is pulled out and cut to the cutting blade. When the rocking plate returns to the fixed adhesive portion by the spring, tension is applied to the fixed adhesive portion and the adhesive tape. Therefore, there is a problem that the portion attached to the fixed adhesive portion is easily peeled off and the tape cannot be formed, and there is a problem that the cutting blade is exposed and a cutting blade having high cutting ability cannot be mounted.

  The present invention solves the above-mentioned problems, can be mounted with a cutting blade that can be cut well, has good operability, and is surely formed with a folded portion at the end of the adhesive tape, so that the blade does not come out when not in use. A cutter is provided.

  Provided at one end of the support base and the above support base, and is provided on the adhesive tape side in the tape tape support portion for supporting the adhesive tape and the adhesive tape withdrawing path, and can be contacted with the adhesive tape from which the upper end portion is drawn out. The lower end portion is supported between the first rotating member disposed at the position, the stopper provided at the other end of the support base and serving as the adhesive tape cutting position, and the first rotating plate and the stopper. A rotating blade, an urging means for constantly urging the rotating blade toward the adhesive tape, and a contact between the rotating blade and the first rotating plate. A second rotating member arranged at a possible position, and the upper end of the rotating blade is always farther from the adhesive tape drawn out than the upper end of the second rotating member, and the rotating blade Against the stopper against the biasing force of the biasing means When rotating to the upper end of the times moving blade has the upper end of the second pivot plate is configured so as to approach the adhesive tape.

  According to this invention, the cutting blade at the tip of the rotating blade is placed below the tip of the second rotating member, so that the drawn adhesive tape is stuck to the tip of the second rotating plate. However, it is possible to cut the adhesive tape by cutting operation, and at the same time the rotating blade is moved by the biased torsion spring. It can be turned together with the two rotary plates to the tip of the first rotary plate to form a folded portion, but at the same time, the first rotary plate also turns to the tape side and there is no tension between them. The attached tape can be peeled off and the folded part can be formed reliably, and when it is not in use, the cutting blade can be cut well. Good operability There is a point.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an overall configuration. A tape cutter of the present invention is provided with a rotating shaft member 23 which is held at one end of a heavy support base 22 so as to be detachable and rotatable. The rotating shaft member 23 is held at the intermediate portion in the length direction of the support base 22 that is configured such that the annular core 11a of the adhesive tape 11 is detachably fitted.

  The other end of the support base 22 is formed with a standing portion 24 that extends to a position slightly higher than the center position of the rotary shaft member 23, and the standing portion 24 has a cutting position of the rotary blade 37 that cuts the adhesive tape 11. A stopper 39 is provided. A space between the stopper 39 and the adhesive tape 11 is a drawing path for pulling out the adhesive tape 11 that is cut to a desired length.

  On the adhesive tape side, a first rotating plate 30 having a to-be-adhered portion 33 at the tip is provided together with a rotating shaft 31, and this rotating range rotates a small distance between the fixed portions 32 and 41. The second rotating plate 34 is rotatably supported by a second rotating shaft 38 and rotates to a stopper 39. A rotating blade 37 is interposed between the second rotating plate 34 and the stopper 39. Since the torsion spring 40 is provided so as to be rotatably supported by the tape 38 and always biased toward the tape side, the rotary blade 37 moves the second rotary plate 34 to the first rotary plate 30 side. Is pressed against.

  When the first rotary plate tip 33 and the second rotary plate tip 35 are in contact, the cutting blade tip of the rotary blade 37 is positioned below the second rotary plate tip 33. When the rotation shaft is provided, the distal end portion 35 of the second rotation plate is bent inward at an appropriate angle over the entire width, and when the distal end portion 35 is pulled out to the stopper 39 attached to the drawn adhesive tape. The rotary shafts are provided so that the cutting blade portion at the tip of the rotary blade 37 protrudes above the tip of the second rotary plate 35 by the amount necessary for tape cutting.

The tape cutter configured as described above is used as follows.
Pulling out the end of the adhesive tape 11 in a little more detail, as shown by the phantom line in FIG. 2, the adhesive tape is pulled out, and the adhesive tape is attached to the tip 35 of the second rotating plate 34. The cutting blade at the tip of the moving blade 37 is below the upper end of the second rotating plate 34, and the tape is further pulled out, and the adhesive tape is stopped from the tip of the adhesive tape to a desired length by the stopper 39. However, since the tip of the cutting blade comes out above the tip of the second rotary plate 35 immediately before reaching the stopper position, the adhesive tape can be cut by the cutting operation.

  Simultaneously with the cutting, the rotating blade 37 is rotated in the direction of the first rotating plate 30 by the torsion spring 40 as shown by the phantom line in FIG. 3, and the second rotating plate 34 is also moved in the direction of the first rotating plate 30. When the second rotary plate tip 35 approaches the first rotary plate 30, the rotary blade tip portion of the rotary blade 37 is lowered below the second rotary plate tip 33, and the tape is rotated. Is attached to the second rotating plate tip 35, so that a folded portion is formed with the first rotating plate tip 33. At the same time, the first rotating plate 30 slightly returns to the tape side. Since some slack is generated in 25 and the tension is lost, peeling of the adhesive tape stuck to the first rotating plate tip 33 is eliminated, and a folded portion is surely formed.

  The adhesive tape is mostly used as a temporary fix, and when it is securely bonded, it is rarely used from the viewpoint of durability and reliability. If it can be applied, the purpose of temporary fixing can be further achieved, and scratches and dirt can be minimized when the attached wrapping paper is peeled off.

  In addition, there is a merit that leads to ecology such that they can be reused, and since the cutting blade does not come out on the surface when not in use, it can be attached with a cutting blade that can cut well with high cutting ability, and it is extremely safe with good operability, Safe to use in any environment.
