Description

[Technical field]

[0001] The present invention relates to a tape cutter, and more particularly to a combination tape application shaft. [Background technology]

[0002] When using tapes, the tapes are loaded onto a rotating shaft, which is then loaded into various tape cutters, such as tabletop tape cutters, hand tape cutters, bag sealers, etc. The various tapes available on the market are of different sizes, and therefore have different inner diameters of the shaft holes, which is inconvenient to use. In particular, in order to accommodate different sizes of cellophane tape, it is necessary to purchase tape cutters with different sizes of rotating shafts for loading the tape. In other words, in order to use different sizes of cellophane tape, tape cutters of different sizes are required, which is a hassle for consumers and tape cutter manufacturers. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE PRESENT EMBODIMENT The main object of the present invention is to provide a composite tape mounting shaft which is simple in structure and assembly and can be used with two sizes of cellophane tape, particularly 3 inch and 3.5 inch. [Means for solving the problem]

[0004] In order to solve the above-mentioned problems, the composite tape mounting rotating shaft comprises a rotating member and a sleeve. The rotating member has a shaft, an axial hole penetrating the shaft, and a plurality of claws arranged to protrude radially outward from the shaft with the shaft as the center of a circle. The sleeve has an outer peripheral annular portion and a plurality of locking holes. The multiple locking holes are arranged corresponding to the shapes and positions of the multiple claws of the rotating member. The multiple locking holes are interconnected to form a storage space. The rotating member is stored in the storage space, and each of the claws fits into the corresponding locking holes.

[0005] When using the composite tape mounting rotary shaft, one cellophane tape can be mounted on the rotating member, or the rotating member and the sleeve can be joined together and then different sizes of cellophane tape can be mounted thereon.

[0006] In a more preferable case, each of the plurality of claws has two side walls, one end of each of which is connected to the shaft and the other ends of which are connected to each other to form a connecting portion.

[0007] In a more preferable case, the two side walls have a protruding locking portion at the connecting position. Radially outward The projection 14 is disposed so as to protrude in the direction of the arrow. [Brief description of the drawings]

[0009] The present invention will now be described with reference to the accompanying drawings, in which: FIG. 1 is a perspective view of a multi-tape loading shaft according to the present invention; FIG. 2 is a perspective view of a multi-tape loading shaft according to the present invention;

[0010] (One embodiment) As shown in FIGS. 1 to 4, a composite tape mounting shaft according to an embodiment of the present invention includes a rotating member 10 and a sleeve 20. As shown in FIG.

[0011] The rotating member 10 has a shaft 11, an axial hole 12 penetrating the shaft 11, and a plurality of claw portions 13 arranged to protrude radially outward from the shaft 11 with the shaft 11 as the center of a circle. In this embodiment, an example having three claw portions 13 will be described. That is, the number of claw portions 13 is not limited to three, and may be four, five, or six. Each claw portion 13 has two side walls 131. One end of each of the two side walls 131 is connected to the shaft 11, and the other ends are connected to each other to form an arc-shaped connecting portion 132. The two side walls 131 have a protruding locking portion 133 at the connecting position. The protruding locking portion 133 is connected to the shaft 11. Radially outward Since the width of each of the claws 13 is smaller than the axial width of the shaft 11, there are two separate annular walls 14 between the claws 13 and both ends of the shaft 11, as shown in FIG.

[0012] The sleeve 20 has an outer peripheral annular portion 21, a plurality of convex portions 22, and a plurality of locking holes 23. The plurality of convex portions 22 are formed on the surface of the outer peripheral annular portion 21 and are arranged in the radial direction away from the center of the outer peripheral annular portion 21. The plurality of locking holes 23 correspond to the shapes and positions of the plurality of claw portions 13 of the rotating member 10. The plurality of locking holes 23 are connected to each other to form a storage space 24. The rotating member 10 is stored in the storage space 24, and each of the claw portions 13 fits into the corresponding locking holes 23. In this embodiment, the locking holes 23 of the sleeve 20 are arranged to correspond to the arc-shaped connecting portions 132 of the claw portions 13, and have concave portions 25 on their sides. The convex locking portions 133 of the claw portions 13 fit into the concave portions 25.

[0013] Due to the above-mentioned structural features, the composite tape attachment shaft according to the present invention can be applied to tape cutters with different tape sizes and uses, such as tabletop tape cutters, hand tape cutters, and bag sealers. When using the composite tape attachment shaft according to the present invention, it is sufficient to mount the composite tape attachment shaft according to the present invention to the tape cutter via the shaft hole 12 of the rotating member 10 or the shaft 11 of the rotating member 10. As shown in Figure 7, the composite tape attachment shaft according to the present invention is mounted to the bag sealer by the annular wall 14 between the shaft 11 and the claw 13.

[0014] The outermost diameter of the rotating member 10 corresponds to the inner diameter of the cylindrical portion T of the cellophane tape having a diameter of 3 inches. When using 3-inch cellophane tape, it is sufficient to use only the rotating member 10. When the rotating member 10 fits into the cylindrical portion T of the cellophane tape, the multiple protruding engagement portions 133 come into contact with the inner wall of the cylindrical portion T of the cellophane tape as shown in FIG. 5.

[0015] When using 3.5 inch cellophane tape, the sleeve 20 is placed over the rotating member 10 and the multiple protruding engagement portions 133 are fitted into the engagement holes 23 of the sleeve 20 to join the rotating member 10 and the sleeve 20 together. Next, as shown in Figure 6, the outer peripheral annular portion 21 of the sleeve 20 is covered with the cylindrical portion T of the cellophane tape and the protruding portions 22 of the outer peripheral annular portion 21 are brought into contact with the inner wall of the cylindrical portion T of the cellophane tape, and the tape cutter can be attached to the shaft 11 of the rotating member 10 as the rotation axis for use. Due to the structural features described above, the same tape cutter can be used for two different sizes of cellophane tape.

[0016] As described above, the present invention is not limited to the above-described embodiment, and can be embodied in various forms without departing from the spirit of the invention. [Explanation of symbols]
