Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive tape technology, and in particular to a steel wire adhesive tape. Background Technology
[0002] When ships, trucks, and cars are powder coated or painted, steel wire tape is needed for cutting and separating the edges. The specific operation is as follows: stick the steel wire tape on the exterior of the car to distinguish the spraying area. After the spraying is completed, remove the masking paper, then pull up the thin steel wire in the cutting tape, and then cut the edge of the wear-resistant elastic coating film into a neat and beautiful straight edge. This completes the cutting and separating of the edges.
[0003] Existing steel wire tape is only suitable for simple straight-line application and is not suitable for applying tape to areas enclosed by curves, such as circular or elliptical areas. When steel wire tape is bent to form a circular or elliptical area, one side of the tape cannot remain parallel to the other. Furthermore, when forming a circular or elliptical area, the two sides of the steel wire tape form an inner circumference and an outer circumference, which are not the same length. Because the two sides of the existing steel wire tape are parallel to each other, the two sides of the tape are stretched and compressed respectively. This can result in the outer circumference lifting up and failing to adhere to the car's exterior, or the inner circumference being compressed and lifting up, also failing to adhere to the car's exterior. Consequently, the steel wire tape cannot form a neat boundary, resulting in an unsightly and aesthetically pleasing edge after spraying. Utility Model Content

[0035] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.
[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0038] This utility model embodiment provides a steel wire tape, such as Figure 1-3 As shown, it includes double-sided tape 1 and masking paper 2 pasted on one side of the double-sided tape 1. The double-sided tape 1 is folded in half to form a double-layer structure, and at least one steel wire 3 is provided in the double-layer structure.
[0039] The double-sided tape 1 has multiple notches 101 arranged at equal intervals on both sides, and the notches 101 are triangular in structure.
[0040] The masking paper 2 includes a masking paper body 202 and a plurality of redundant structures 201. The plurality of redundant structures 201 are equidistantly arranged on the masking paper body 202 and connected to the two sides of the masking paper body 202.
[0041] The redundant structure 201 is a folded structure, and the position of the redundant structure 201 corresponds to the position of the notch 101. The redundant structure 201 extends and contracts adaptively as the shielding paper body 202 bends.
[0042] In this embodiment, the multiple notches 101 on the double-sided tape 1 and the multiple redundant structures 201 on the masking paper 2 make adaptive extension and compression actions when the steel wire tape is bent, so as to adapt to the change in the length of the two sides of the steel wire tape, thereby solving the problem that the steel wire tape cannot form a relatively neat boundary when it is bent and attached.
[0043] Specifically, when the steel wire tape is bent, the two sides of the double-sided tape 1 are stretched and compressed respectively because their lengths remain unchanged. When one side of the double-sided tape 1 is stretched, the redundant structure 201 and the notch 101 are subjected to tension. The redundant structure 201 and the notch 101 unfold to increase the length of the outer side of the double-sided tape 1. When one side of the double-sided tape 1 is compressed, the redundant structure 201 and the notch 101 are compressed and converged to reduce the length of the outer side of the double-sided tape 1. This achieves a change in the length of the two sides of the double-sided tape 1. The two sides of the double-sided tape 1 are not subjected to stretching and compression and do not undergo physical changes, thus forming a relatively neat boundary.
[0044] like Figure 4 As shown, the double-layer structure is formed by folding the two sides of the double-sided tape 1 towards the middle, and two steel wires 3 are provided inside the double-layer structure;
[0045] The two steel wires 3 are respectively arranged on both sides of the double-layer structure and are adaptively bent along the notch 101.
[0046] In this embodiment, the purpose of setting a steel wire 3 on each side of the double-sided tape 1 is to enhance the overall structural strength of the steel wire tape, prevent the steel wire tape from being damaged when it is bent and applied. At the same time, due to the increased structural strength, the steel wire tape is less likely to flip or bulge when it is bent and applied, further ensuring that the steel wire tape can form a relatively neat boundary when it is bent and applied.
[0047] Furthermore, the steel wire 3 bends along the notch 101 to form a corner 301, and the corner 301 is also a triangular structure.
[0048] In this embodiment, the corner 301 is set as a triangular structure. In the triangular structure, the two sides can rotate a certain amount around one endpoint to increase or decrease the angle between the two sides.
[0049] Furthermore, the redundant structure 201 is a U-shaped fold body formed by longitudinally folding the masking paper body 202; the U-shaped fold body includes a folding part 2011 and a folding opening 2012, and the folding part 2011 is disposed on the side of the masking paper 2 away from the double-sided adhesive tape 1.
[0050] In this embodiment, the U-shaped fold is a first specific embodiment of the redundant structure 201, such as... Figure 3As shown, its structure is simple. The two ends of the U-shaped fold can adapt to the change in length of both sides of the double-sided tape 1 when it is bent and applied. Specifically, when one side of the double-sided tape 1 is compressed, the fold opening 2012 closes, thereby reducing the overall length of one side of the double-sided tape 1. When one side of the double-sided tape 1 is stretched, the fold opening 2012 opens, and the fold part 2011 cooperates with the fold opening 2012 to open, thereby increasing the overall length of one side of the double-sided tape 1.
[0051] Furthermore, the width of the fold opening 2012 is the same as the width of the notch 101;
[0052] The notches 101 on both sides of the double-sided tape 1 are aligned with each other. The number of U-shaped folds is the same as the number of notches 101 on one side of the double-sided tape 1. The position of the fold opening 2012 corresponds to the position of the notches 101 on both sides of the double-sided tape 1.
[0053] In this embodiment, the width of the fold opening 2012 is the same as the width of the notch 101 in order to ensure that the U-shaped fold and the notch 101 can be extended and compressed simultaneously.
[0054] Furthermore, the redundant structure 201 is a conical groove disposed on both sides of the masking paper body 202, the conical groove protruding from the side of the masking paper 2 away from the double-sided tape 1;
[0055] The number and position of the conical grooves correspond one-to-one with the number and position of the notches 101. It should be noted that, as... Figure 5 As shown, the conical groove includes two identical right-angled triangles. The right-angled sides of the two right-angled triangles are connected to each other, and the hypotenuses of the two right-angled triangles are connected to the masking paper body 202. The right-angled triangles protrude from the side of the masking paper 2 away from the double-sided tape 1, and the area of the masking paper 2 covered by the two right-angled triangles is cut to form a triangular opening. The triangular opening has the same structure as the notch 101.
[0056] In this embodiment, the conical groove is a second specific embodiment of the redundant structure 201. The structure at the bottom of the conical groove is the same as or similar to the structure of the notch 101, which can more accurately synchronize with the stretching and contraction of the notch 101, ensuring the linkage of the overall structure of the steel wire tape during the bending and application process.
[0057] Furthermore, the width of the double-sided tape 1 is the same as the width of the masking paper 2, and the ends of the conical grooves correspond one-to-one with the ends of the notches 101.
[0058] In this embodiment, the purpose of having the ends of the conical groove correspond one-to-one with the ends of the notch 101 is to ensure that the conical groove can be more precisely synchronized with the stretching and contraction of the notch 101.
[0059] Furthermore, the included angle of the notch 101 is 30°-90°;
[0060] The maximum distance from the end of the notch 101 to the outer side of the double-sided tape 1 is one-fifth of the width of the double-sided tape 1.
[0061] In this embodiment, the included angle of the notch 101 can determine the maximum distance between the end of the notch 101 and the outer side of the double-sided tape 1, as well as the overall structural strength of the steel wire tape. When the included angle of the notch 101 is 30°-90°, the maximum distance between the end of the notch 101 and the outer side of the double-sided tape 1, as well as the overall structural strength of the steel wire tape, can be reasonably balanced.
[0062] Furthermore, the thickness of the redundant structure 201 is less than the thickness of the shielding paper body 202.
[0063] In this embodiment, the thickness of the redundant structure 201 can increase or decrease the ductility of the redundant structure 201. If the thickness of the redundant structure 201 is less than the thickness of the shielding paper body 202, the structural strength of the redundant structure 201 can be reduced and the ductility of the redundant structure 201 can be increased.
[0064] Furthermore, the redundant structure 201 is an opening provided on both sides of the shielding paper body 202. The opening is a triangular structure, and the ends of the opening correspond one-to-one with the ends of the notch 101.
[0065] The number and location of the openings correspond one-to-one with the number and location of the notches 101.
[0066] In this embodiment, the opening is a third specific embodiment of the redundant structure 201, such as... Figure 6 As shown, its structure is the same as that of notch 101, and it can stretch and shrink synchronously with notch 101. Compared with the specific embodiments of the three redundant structures 201 mentioned above, its process is simple and the molding cost is low.
[0067] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
