The paper web 2 is connected to the reel 1. The winding drum 1 is fixedly provided with a winding shaft 14. The end plate 16 of the winding drum 1 is provided with shaft holes 17 corresponding to the winding shaft 14, and two ends of the winding shaft 14 extend out of the winding drum 1 from the corresponding shaft holes 17. The take-up reel 14 can be rotated when the paper tape 2 is drawn or wound. One end of the paper tape 2 positioned inside the winding drum 1 is connected with a winding shaft 14, and one end of the paper tape 2 positioned outside the winding drum 1 is fixedly connected with a positioning board card 3 which can be pinched by fingers; the length, width or thickness of the positioning board card 3 is larger than the paper opening 11.

In this embodiment, the length, thickness or width of the positioning board card 3 is greater than the corresponding length, width or thickness of the paper opening 11 of the roll 1, so that the positioning board card 3 cannot enter the roll 1 through the paper opening 11, and the paper tape 2 is prevented from being excessively wound into the roll 1, which results in the phenomenon that the paper tape 2 cannot be normally used.

The implementation principle of the tape sticking reel convenient to store provided by the embodiment of the utility model is as follows: one end of the paper strap 2 (as will be appreciated by those skilled in the art, the paper strap 2 is a flexible, spoolable strap of a length in this embodiment) is connected to a take-up spool 14. The paper tape 2 is rolled in the reel 1 through the rolling shaft 14, the locating board card 3 is held when in use, the paper tape 2 is drawn outwards, and paper-paste products on the paper tape 2 are selected. After use, the winding shaft 14 is rotated to extend out of one end of the outside of the winding drum 1, and the paper tape 2 is rewound into the winding drum 1 again. The paper tape 2 is conveniently contained in the winding drum 1, and the paper tape 2 is not stored in a book or paper card mode any more, and is convenient to carry and avoid extrusion in a box containing mode. Meanwhile, the contents on the paper tape 2 are displayed in a drawing mode, a specific sequence of pictures can be formed, and the user experience (including use interestingness) is greatly improved.

The embodiment of the utility model discloses a tape pasting reel convenient to store. As shown in fig. 4, this embodiment differs from the other embodiments in that: the positioning board card comprises two clamping pieces 31, and one end of the paper tape 2 positioned outside the winding drum 1 is clamped and fixed between the two clamping pieces 31.

The implementation principle of the tape sticking reel convenient to store provided by the embodiment of the utility model is as follows: in this embodiment the clamping piece 31 is glued to the paper web 2. When in use, fingers grip the two side clamping sheets 31 to draw the paper tape 2. The double-sided grip tab 31 protects the end of the paper strap 2 on the one hand and facilitates gripping of the paper strap 2 on the other hand.

In other embodiments of the present utility model, the use of the locating plate card 3 with the single-sided clamping piece 31 or other locating plate cards 3 that cannot protect the end of the paper strap 2 is found to be inferior to this embodiment.

The embodiment of the utility model discloses a tape pasting reel convenient to store. As shown in fig. 5, this embodiment differs from the other embodiments in that: one side of the two clamping pieces 31 is fixedly connected through a connecting part 32.

The implementation principle of the tape sticking reel convenient to store provided by the embodiment of the utility model is as follows: the two clamping sheets 31 which are originally split are formed into a whole, so that the integrally formed positioning board card 3 can be used in the material selection production, the production efficiency is convenient to improve, and the production cost is reduced. Meanwhile, a protective surface is added, and the protection performance on the end part of the paper tape 2 is further improved.

The embodiment of the utility model discloses a tape pasting reel convenient to store. As shown in fig. 2 and 3, this embodiment differs from the other embodiments in that: the winding drum 1 is a split winding drum 1, and the split winding drum 1 comprises a first split drum 12 and a second split drum 13; the first sub-cylinder 12 and the second sub-cylinder 13 are buckled to form a cavity capable of accommodating the winding shaft 14; the winding shaft 14 comprises a shaft body 141 and two baffle plates 142 fixedly arranged on the shaft body 141, and when the winding shaft is in a winding state, the paper tape 2 is wound on the periphery of the shaft body 141 between the two baffle plates 142; the flap 142 is located inside the spool 1.

The first sub-cylinder 12 and the second sub-cylinder 13 are detachably fixed through a buckling mechanism. One part of the shaft hole 17 is positioned on the first sub-cylinder 12, the other part of the shaft hole 17 is positioned on the second sub-cylinder 13, and when the first sub-cylinder 12 and the second sub-cylinder 13 are buckled, a complete shaft hole 17 is formed.

The snap-fit mechanism comprises a bump 18 on the end plate 16 of the first barrel 12 and a notch 19 on the end plate 16 of the second barrel 13; the convex point 18 protrudes outwards from the end plate 16 of the first sub-cylinder 12, and the shape of the notch 19 is matched with that of the convex point 18; when the first sub-cylinder 12 and the second sub-cylinder 13 are buckled and fixed, the convex points 18 are clamped in the notch 19.

Further, in some embodiments, the blocking pieces 142 are annular, the radius of the blocking piece 142 is larger than that of the shaft hole 17, and the two blocking pieces 142 cannot pass through the shaft hole 17 and are accommodated inside the winding drum 1. In other embodiments, the blocking pieces 142 extend along the outer circumference of the shaft 141 and protrude outside the shaft 141, and a position in which the paper tape 2 is wound is formed between the blocking pieces 142. The stopper 142 prevents the tape 2 from excessively moving in the axial direction of the shaft 141.

Referring to fig. 6, the shaft body 141 is provided with a bayonet 1411. The end of the strip 2 inside the reel 1 extends into the bayonet 1411. The bayonet 1411 extends a certain length in the axial direction of the shaft 141 and penetrates the shaft 141 (in this embodiment, the bayonet 1411 has no partition 1412, and other structures are identical to those of fig. 6).

The implementation principle of the tape sticking reel convenient to store provided by the embodiment of the utility model is as follows: in the process of assembling the paper tape 2, the winding drum 1 is separated, the shaft body 141 is taken out, the paper tape 2 and the shaft body 141 are fixed and coiled, then the shaft body 141 is put into the first sub-drum 12, and finally the second sub-drum 13 is buckled with the first sub-drum 12. When fixing the paper tape 2, one end of the paper tape 2 is inserted into the bayonet 1411 and then is tightly coiled along the periphery of the shaft 141, so that the end of the paper tape 2 is not easy to separate along with the rotation of the shaft 141. The protruding points 18 are provided with arc surfaces or inclined surfaces to a certain extent, in the process of buckling the first sub-cylinder 12 and the second sub-cylinder 13, the protruding points 18 press the end plate 16 where the notch 19 is located from the arc surfaces, so that the end plate 16 is elastically deformed, and is slightly bent outwards until the protruding points 18 reach the position where the notch 19 is located (at the moment, a 'click' sound is generated), the protruding points are buckled into the notch 19, and the deformation returns, so that buckling is completed.

In some embodiments of the present utility model, without the bayonet 1411 structure, the paper tape 2 is directly coiled on the shaft 141, and the product using effect of these embodiments is slightly inferior to that of the embodiment with the bayonet 1411 because the relative slip between the paper tape 2 and the shaft 141 appears to some extent during the rolling process of the paper tape 2.

The embodiment of the utility model discloses a tape pasting reel convenient to store. As shown in fig. 6 and 7, this embodiment is different from the other embodiments in that: the bayonet 1411 is fixedly provided with a separation rib 1412 inside, the separation rib 1412 separates the bayonet 1411 into an upper part and a lower part, and the separation rib 1412 extends along the length direction of the bayonet 1411.

The implementation principle of the tape sticking reel convenient to store provided by the embodiment of the utility model is as follows: when the paper tape 2 is fixed, one end of the paper tape 2 is inserted from the upper part of the bayonet 1411, passes through the upper part of the bayonet 1411, and then turns into the lower part of the bayonet 1411 to form a turning anti-drop structure. In this way, the connection stability between the paper tape 2 and the shaft body 141 is further improved, and the phenomenon of slipping and spinning of the reel in the winding process is further reduced.

In addition, we further describe the positioning board 3: referring to fig. 8, in the design process, the arrangement of the structure of the positioning board card 3 is finally determined by considering the easy-rolling property of the whole cylindrical product. In the embodiment with the locating board card 3, the structure that the locating board card 3 and the winding drum 1 are combined has very good rolling stopping effect when being convenient for storage and use, when the winding drum 1 is thrown on a table top, a desk or falls on the ground, the winding drum 1 inevitably has a trend of relative rolling due to the fact that the winding drum 1 is in a cylindrical shape, and in the process, the paper tape 2 is fixedly connected with the locating board card 3 in a relatively straight structure, so that the rolling distance is reduced. In one embodiment of the utility model, the length h of the locating plate 3 is equal to the diameter of the spool 1. In other embodiments of the utility model, the length h of the positioning card 3 is greater than the diameter of the spool 1, where the slowing effect is optimal. In other embodiments of the present utility model, the length h of the positioning card 3 is reduced to be smaller than the diameter of the reel 1, and the rolling slowing effect is reduced along with the reduction of h, but the rolling slowing effect is still provided.

The embodiment of the utility model discloses a tape pasting reel convenient to store. As shown in fig. 9 and 10, this embodiment differs from the other embodiments in that: the end plate 16 of the second sub-cylinder 13 is fixedly provided with the plectrum part 4, the notch 19 is arranged on the plectrum part 4, when the second sub-cylinder 13 is buckled with the first sub-cylinder 12, the plectrum part 4 deforms under the extrusion of the convex point 18, and the convex point 18 enters the notch 19 and then the plectrum part 4 recovers the deformation. The paddle portion 4 is provided with a bevel 41 on a side thereof adjacent to the end plate 16 of the first sub-cartridge 12. In the present embodiment, the paddle portion 4 is formed by extending the end plate 16 outward.

The implementation principle of the tape sticking reel convenient to store provided by the embodiment of the utility model is as follows: referring to fig. 10, the finger tip pulls the paddle portion 4 outwardly with the bevel 41 as a support point. The finger tip is forced outwards by taking the bevel 41 position as a supporting point, and simultaneously the first sub-cylinder 12 and the second sub-cylinder 13 are forced towards the separating direction, so that the separation can be performed. The removal speed is faster than in other embodiments where the bevel 41 is not provided, and no pry plate is needed for force application.

As shown in fig. 10 and 11, the portion of the take-up shaft 14 extending out of the roll 1 is optimized for further improvement of the ease of use. One of the modes is as follows: a positioning piece 5 is fixedly arranged at the end part of the shaft body 141, and the positioning piece 5 is positioned outside the winding drum 1. Another way is: the end of the shaft body 141 is fixedly provided with a rubber sleeve 6, and the rubber sleeve 6 is positioned outside the winding drum 1.

When the paper tape 2 is required to be reeled after being drawn out, the shaft body 141 is required to be pinched by fingers, and the shaft body 141 has a short extending end due to the compact overall structure, so that the phenomenon of hand release easily occurs in the rotation process. The two fingers hold the end of the shaft 141, and the outer sides of the finger abdomen use the positioning piece 5 as a force application point to prevent the hand from being pulled off. The scheme of the rubber sleeve 6 is adopted in the same way.

Preferably, at least a part of the lateral plates 15 of the roll 1 is a transparent lateral plate 15, and the transparent lateral plate 15 forms a window capable of presenting the content on the paper tape 2 at the corresponding position inside the roll 1 to a user.

The implementation principle of the tape sticking reel convenient to store provided by the embodiment of the utility model is as follows: the characters and icons on the rolled paper tape 2 are presented to a user through the window, and can be selected in the process of drawing the paper tape 2. In addition, in some embodiments, the tape 2 has a scene with a more continuous pattern, which can provide a manual animation when the tape 2 is pulled more quickly.

In some embodiments of the present utility model, the first and/or second cartridges 12, 13 are made of a transparent material.

The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
