Description

Technical Field

[0001] This utility model belongs to the field of adhesive tape technology, and in particular relates to a packaging adhesive tape. Background Technology

[0002] Adhesive tape is a widely used adhesive material in daily life and industrial fields. Existing adhesive tapes have the following drawbacks: the tape is exposed, which makes it susceptible to damage from external impacts, and it is also prone to accumulating dust and dirt, affecting its future use.

[0003] Existing patent document (publication number: CN223329233U) discloses "a packaging tape", which also has the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a packaging tape with a novel structure. The protective shell protects the tape body and prevents the tape body from accumulating dust and dirt, which would affect its next use. The protective shell is easy to disassemble and facilitates the replacement of the tape body.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A packaging tape includes a tape body, characterized in that: the tape body is covered by a protective shell, the protective shell having an outlet for the head of the tape body to pass through; the protective shell includes two half-shells and a central shaft, the tape body is sleeved on the central shaft, a gap exists between the roll of the tape body and the central shaft, the inner side of the half-shells has a protrusion, and both sides of the central shaft have positioning grooves corresponding to the protrusions, the central shaft is detachably connected to the half-shells. This tape has a novel structure; the protective shell protects the tape body, preventing the tape body from accumulating dust and affecting its next use; the protective shell is easy to disassemble, facilitating the replacement of the tape body.

[0007] Furthermore, an elastic band connects the two half-shells, and a limiting groove corresponding to the elastic band is formed on the side of the half-shell. When the elastic band is embedded in the limiting groove, it cannot freely come out of the limiting groove, resulting in high installation stability. The elastic band clamps the two half-shells together through its elastic force, preventing the half-shells from separating from the central shaft, thus ensuring reliable assembly.

[0008] Furthermore, a magnet is provided on the protrusion, and an iron block is provided in the positioning groove. The iron block and the magnet are attracted by magnetism. Through the magnetic attraction, the protrusion is restricted from freely coming out of the positioning groove. The assembly is reliable, replacing the screw fixing method. The operation is simple, labor-saving and convenient.

[0009] Furthermore, the gap is 3-6mm. Reasonably controlling the gap size ensures that it does not affect the assembly of the central shaft and the tape body, and also ensures that the drum rotates smoothly and the tape body is easily pulled out.

[0010] Furthermore, a toothed blade is provided on one side of the outlet, which can be used to cut the peeled portion of the tape body without the need for external cutting tools, thus improving convenience.

[0011] Furthermore, the tape body includes a base layer, a biodegradable layer, and an abrasion-resistant layer, with the biodegradable layer located between the abrasion-resistant layer and the base layer. The abrasion-resistant layer improves the abrasion resistance of the tape body, making it less prone to wear and breakage; the biodegradable layer improves the biodegradability of the tape body, making it environmentally friendly.

[0012] Furthermore, the protective case is transparent, allowing users to easily see the tape itself and make the process simple and convenient.

[0013] Furthermore, the cross-section of the protrusion is a polygonal structure, which on the one hand restricts relative rotation between the half-shell and the central axis, resulting in high stability of the assembled structure, and on the other hand facilitates the alignment of the two half-shells to form a complete protective shell, reducing the difficulty of docking.

[0014] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0015] 1. The protective shell protects the tape itself, preventing it from accumulating dust and dirt, which could affect its future use.

[0016] 2. The elastic band clamps the two half-shells together with its elasticity, preventing the half-shells from separating from the central shaft. This makes the protective shell less likely to fall apart, ensuring reliable assembly. It replaces screw fixing, saving effort and making the process convenient.

[0017] 3. By using magnets to attract iron blocks, the protrusions are prevented from freely detaching from the positioning grooves. This achieves accurate alignment between the half-shell and the central shaft, ensuring that the two are connected together and cannot be separated freely. The assembly is reliable, replacing screw fixation, and is simple, labor-saving, and convenient to operate. Attached Figure Description

Detailed Implementation

[0028] like Figures 1 to 4 The image shown is an embodiment of this utility model.

[0029] A packaging tape includes a tape body 1 with a roll 2 at its center. The tape body 1 includes a base layer 3, a biodegradable layer 4, and an abrasion-resistant layer 5. The base layer 3 is made of polylactic acid. The biodegradable layer 4 is bonded to the base layer 3 and is made of biomass fiber material, which improves the biodegradability of the tape body 1 and makes it environmentally friendly. The abrasion-resistant layer 5 is coated on the outer surface of the biodegradable layer 4 and is made of polyurethane coating, which improves the abrasion resistance of the tape body 1 and makes it less prone to wear and breakage.

[0030] The tape body 1 is covered by a protective shell 6. The protective shell 6 has an outlet 7 for the head of the tape body 1 to pass through. The protective shell 6 protects the tape body 1, preventing dust and dirt accumulation that could affect its next use. The protective shell 6 is transparent, allowing users to easily see the condition of the tape body 1 during use, making it simple and convenient.

[0031] A toothed blade 8 is provided on one side of the outlet 7. The toothed blade 8 can be used to cut the peeled part of the tape body 1 without the need for external cutting tools, which improves convenience.

[0032] The protective shell 6 includes two half shells 9 and a central shaft 10. The tape body 1 is fitted onto the central shaft 10. The length of the central shaft 10 is greater than the length of the drum 2. The gap between the drum 2 and the central shaft 10 is 3-6mm. By reasonably controlling the size of the gap, on the one hand, it does not affect the assembly of the central shaft 10 and the tape body 1, and on the other hand, it can ensure that the drum 2 rotates smoothly and the tape body 1 can be pulled out easily.

[0033] The inner side of the half shell 9 is provided with a protrusion 11, and both sides of the central shaft 10 are provided with positioning grooves 12 corresponding to the protrusion 11. An elastic band 13 is connected between the two half shells 9. The elastic band 13 is made of elastic fiber. The side of the half shell 9 is symmetrically provided with limiting grooves 14 corresponding to the elastic band 13.

[0034] During assembly, first insert the central shaft 10 into the spool 2, then insert the protrusion 11 into the positioning groove 12 so that the two half-shells 9 fit around the central shaft 10. Next, insert the elastic band 13 into the limiting groove 14 so that the elastic band 13 fits around the two half-shells 9. The elastic band 13 cannot freely come out of the limiting groove 14, resulting in high installation stability. The elastic band 13 clamps the two half-shells 9 with elastic force, preventing the half-shells 9 from separating from the central shaft 10. The protective shell 6 is not easy to come apart freely, making assembly reliable. It replaces the screw fixing method, saving effort and making it convenient. The protective shell 6 is easy to disassemble, making it easy to replace the tape body 1.

[0035] The cross-section of the protrusion 11 is a polygonal structure, which on the one hand restricts the relative rotation between the half shell 9 and the central axis 10, resulting in high stability of the assembled structure; on the other hand, it facilitates the alignment of the two half shells 9 to form a complete protective shell 6, reducing the difficulty of docking.

[0036] like Figures 5 to 7 The image shown is a second embodiment of this utility model.

[0037] In the technical solution based on Embodiment 1, a magnet 15 is fixed on the protrusion 11, and an iron block 16 is fixed in the positioning groove 12. The iron block 16 and the magnet 15 are magnetically attracted to each other.

[0038] Insert the protrusion 11 into the positioning groove 12 so that the magnet 15 and the iron block 16 are attracted to each other, thus preventing the protrusion 11 from freely coming out of the positioning groove 12. This not only achieves accurate docking between the half shell 9 and the central shaft 10, but also connects the two together so that they cannot be separated freely. The assembly is reliable, replaces the screw fixing method, and is simple, labor-saving and convenient to operate.

[0039] like Figure 8 The image shown is Embodiment 3 of this utility model.

[0040] Combining the technical solutions of Embodiment 1 and Embodiment 2, the elastic band 13 and the adsorption of the iron block 16 and the magnet 15 effectively restrict the separation of the half shell 9 from the central shaft 10, ensuring reliable assembly. Even when the elastic band 13 breaks or the magnet 15 loses its magnetism, the half shell 9 and the central shaft 10 are not easily separated, resulting in high stability of the assembled structure.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
