Technical Field

[0001] This utility model relates to the field of double-sided tape, and in particular to a double-sided tape that is easy to tear. Background Technology

[0002] Foam double-sided tape, widely used for bonding, fixing, and sealing, has excellent adhesion and cushioning properties. To meet the needs of different sizes and shapes, foam double-sided tape often needs to be cut into shorter pieces during use.

[0003] However, due to the lack of effective cutting guidance, users often encounter uneven cut surfaces when cutting foam double-sided tape. Furthermore, the release paper is prone to breakage during the cutting process, resulting in some foam double-sided tape being exposed and causing material waste. This not only increases production costs but also affects the product's manufacturing quality. Therefore, this solution proposes an easy-to-tear double-sided tape to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided adhesive that is easy to tear, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-sided adhesive tape that is easy to tear, comprising:

[0006] A foam double-sided adhesive, wherein the foam double-sided adhesive is wound into a disc shape, and a through hole is provided in the center of the disc of the foam double-sided adhesive;

[0007] A sealing structure, wherein the sealing structure is wrapped and attached to one side of the double-sided foam adhesive;

[0008] A support mechanism, comprising a support part and a cutting part, wherein the support part is inserted into a through hole and is used for supporting the double-sided foam adhesive during winding; and the cutting part is inserted into the support part and is used for cutting the double-sided foam adhesive and the sealing structure.

[0009] Preferably, the sealing structure includes release paper, which is adhered to one side of the foam double-sided adhesive, and the side of the release paper away from the foam double-sided adhesive has multiple dividing grooves arranged in an array.

[0010] Preferably, the support portion includes a support block, which is inserted into the through hole, and the cutting portion is inserted into the middle of the support block.

[0011] Preferably, a storage groove is provided on one side of the support block, and the cutting part includes a connecting block, one end of which is inserted into the storage groove.

[0012] Preferably, the side wall of the storage slot is provided with a docking slot, and the side of the connecting block is fixedly connected with a docking strip, which is slidably inserted into the docking slot.

[0013] Preferably, the connecting block is provided with a plurality of puncture needles at one end near the support block, and the puncture needles are used for puncturing the foam double-sided adhesive.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention features a structural design for the support mechanism. Traditional foam double-sided tape uses only a cardboard tube as support in the middle of the winding mechanism. In contrast, this design incorporates a cutting section at the support section, which resembles a cardboard tube. When it is necessary to cut the foam double-sided tape, the cutting section is used to puncture and cut the tape, resulting in a neater surface without damaging the release paper. This allows unused foam double-sided tape to continue to be covered and protected, preventing waste. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: This utility model provides the following... Figure 1 and Figure 2The double-sided tape shown includes:

[0024] The foam double-sided adhesive 1 is arranged in a disc shape, and a through hole is provided in the center of the disc.

[0025] It should be noted that the foam double-sided adhesive 1 is prepared by combining a foam substrate and a double-sided coated adhesive. The foam substrate is made of polyurethane, polyethylene, or polypropylene polymers. These materials undergo a foaming process to form a foam structure with good elasticity and toughness. The micro-bubbles of the foam provide excellent cushioning, effectively absorbing impacts and vibrations. The density and thickness of the foam substrate can be adjusted according to different application requirements to achieve the desired performance. Both sides of the foam substrate are coated with a high-performance adhesive, which is one of acrylic, rubber-based, or silicone adhesives. These adhesives have excellent adhesion and temperature resistance, and can form strong bonds on different substrate surfaces.

[0026] A sealing structure is attached to one side of the foam double-sided adhesive 1;

[0027] Specifically, the sealing structure includes release paper 2, which is adhered to one side of the foam double-sided adhesive 1, and multiple dividing grooves 201 are arrayed on the side of the release paper 2 away from the foam double-sided adhesive 1.

[0028] It should be noted that, in order to protect the adhesiveness of the double-sided adhesive, a layer of release paper 2 is covered on the surface of the foam double-sided adhesive. The release paper 2 has a low surface energy, which can prevent the adhesive from adhering when not in use and make it easy for the user to peel off when using. In this solution, after the release paper 2 covers one side of the foam double-sided adhesive 1, the foam double-sided adhesive 1 is wrapped and adhered to the other side to form a disc shape.

[0029] Example 2: This utility model provides the following... Figure 3 - Figure 5 The support mechanism shown is applied to a tearable double-sided adhesive in Embodiment 1. The support mechanism includes a support part and a cutting part. The support part is inserted into the through hole and is used to support the foam double-sided adhesive 1 when it is wrapped. The cutting part is inserted into the support part and is used to cut off the foam double-sided adhesive 1 and the sealing structure.

[0030] Specifically, the support part includes a support block 3, which is inserted into the through hole. The cutting part is inserted into the middle of the support block 3. A storage groove 301 is provided on one side of the support block 3. The cutting part includes a connecting block 4, one end of which is inserted into the storage groove 301.

[0031] It should be noted that when the foam double-sided adhesive 1 needs to be wound into a disc shape, it can be wound around the outer wall of the support block 3. At this time, the support block 3 is equivalent to the cardboard tube structure in the middle of the traditional double-sided adhesive, which is used to support the foam double-sided adhesive 1 to be wound into shape. The outer wall diameter of the connecting block 4 is the same as the opening diameter of the storage groove 301, and the two can form a kind of tenon and mortise type of interlocking.

[0032] Furthermore, the side wall of the storage slot 301 is provided with a docking slot 302, and the side of the connecting block 4 is fixedly connected with a docking strip 401. The docking strip 401 is slidably inserted into the docking slot 302. A plurality of puncture needles 402 are provided at one end of the connecting block 4 near the support block 3. The puncture needles 402 are used for puncturing the foam double-sided adhesive 1.

[0033] It should be noted that the interlocking connection of the connecting strip 401 and the connecting slot 302 guides the interlocking connection between the connecting block 4 and the storage slot 301, thus facilitating the interlocking of the connecting block 4 at the storage slot 301. The piercing needle 402 is used to pierce and punch holes in the release paper 2 and the foam double-sided adhesive 1 to form a tear seam, which facilitates the smooth cutting of the release paper 2 and the foam double-sided adhesive 1, avoiding waste of adhesive caused by uneven cutting. The dividing groove 201 opened in the release paper 2 facilitates the piercing of the piercing needle 402, and provides a reference and guidance for the piercing direction and angle of the piercing needle 402, making the cutting of the release paper 2 and the foam double-sided adhesive 1 more stable.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
