[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] This application provides a paperless double-sided tape, which solves the problem that the adhesion strength between the adhesive and the backing paper of existing tapes gradually weakens over time, and when the tape is finally torn off, glue residue is often left, making it difficult to remove the glue from the object. If a paperless substrate is used as the double-sided tape, it is not easy to cut quickly, and a lot of force is required when peeling off the backing paper, which is inconvenient to use.

[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0035] Example 1:

[0036] This utility model discloses a paperless double-sided adhesive tape, according to the attached... Figures 1-4 As shown, it includes a tape body 1, a limiting frame 2, a support base 3, a cutting unit 4, and a clamping mechanism 5;

[0037] The tape body 1 consists of a substrate layer 11, an adhesive layer 12, and a separator layer 13. The substrate layer 11 serves as the supporting base of the tape, and the adhesive layer 12 is attached to the substrate layer 11, providing adhesion to achieve the adhesive function. The separator layer 13 is used to protect the tape externally, preventing the adhesive layer 12 from being contaminated or sticking when not in use.

[0038] The substrate layer 11 is composed of water-soluble PVA or PLA film, and the adhesive layer 12 is 0.05-0.15mm thick. It is directly coated and cured on the substrate surface to form an integral, non-peelable material.

[0039] The tape body 1 adopts a paperless design. When using it, simply tear off the separator layer 13 to expose the adhesive layer 12 for pasting. Compared with traditional tapes, the paperless design eliminates the need to consider the adhesion between the backing paper and the adhesive, making it less likely to leave residue when the tape is removed.

[0040] The limiting frame 2 is located outside the tape body 1 and provides support for the tape body 1. The limiting frame 2 is provided with a shaft 21, and the tape body 1 is in the shape of a roll with its axis positioned on the shaft 21, which facilitates the rotation and unwinding of the tape body 1.

[0041] The support base 3 is mounted on the limiting frame 2, and the support base 3 is provided with a connecting frame 32 to provide support for the installation of the cutting unit 4.

[0042] The support base 3 serves as the mounting base for the cutting unit 4, ensuring that the cutting unit 4 can stably cut the tape body 1 during operation.

[0043] The cutting unit 4 includes a lead screw 41, a movable plate 42, and a cutter 43. The lead screw 41 is threadedly connected to the connecting frame 32, the movable plate 42 is rotatably connected to the lead screw 41 and slidably connected below the connecting frame 32, and the cutter 43 is mounted on the movable plate 42. The movable plate 42 has a slot 421, and the lead screw 41 has a rotating handle 411 for easy rotation by the operator.

[0044] When the handle 411 is turned, the lead screw 41 rotates. Since the lead screw 41 is threadedly connected to the movable plate 42, the movable plate 42 slides along the connecting frame 32 under the drive of the lead screw 41, thereby driving the cutter 43 to move and cut the tape body 1. The support base 3 has a cutting groove 31 corresponding to the position of the cutter 43. The cutting groove 31 ensures that the cutter 43 can easily cut the tape body 1;

[0045] The clamping mechanism 5 includes a slide 51, a spring 52, and a locking block 53. The slide 51 is slidably connected to the limiting frame 2, the spring 52 is disposed between the slide 51 and the support base 3, and the locking block 53 is disposed on the slide 51 and engages with the tape body 1.

[0046] Spring 52 applies a spring force to slide 51 in the direction of tape body 1, so that the locking block 53 can tightly lock the tape body 1 and prevent the tape body 1 from rotating or loosening when not in use.

[0047] The steps for using this paperless double-sided tape are as follows:

[0048] The central position of the roll-shaped tape body 1 is fitted onto the shaft 21 of the limiting frame 2, and is limited and fixed by the sleeve 22 and the positioning pin 23.

[0049] The spring 52 of the clamping mechanism 5 pushes the slide 51 and the locking block 53, so that the locking block 53 locks the tape body 1, ensuring the stability of the tape body 1 during use.

[0050] Pulling the tape body 1 will cause the tape body 1 to rotate and pull out the tape body 1 of the target length;

[0051] Rotate the handle 411 of the cutting unit 4, the lead screw 41 rotates, driving the movable plate 42 and the cutter 43 to move, cutting the tape body 1 of the target length.

[0052] Tear off the separating layer 13 of the main body of the tape 1 to expose the adhesive layer 12.

[0053] The cut tape is then pasted onto the desired location through the adhesive layer 12 and the substrate layer 11.

[0054] Example 2:

[0055] This utility model discloses a paperless double-sided adhesive tape, according to the attached... Figures 1-4 As shown, it includes a tape body 1, a limiting frame 2, a support base 3, a cutting unit 4, and a clamping mechanism 5;

[0056] The tape body 1 consists of a substrate layer 11, an adhesive layer 12, and a separator layer 13. It adopts a paperless design. The adhesive layer 12 is attached to the substrate layer 11, and the separator layer 13 is used to protect the outside of the tape. The separator layer 13 is torn open when in use.

[0057] The limiting frame 2 is located outside the tape body 1 and supports the tape body 1;

[0058] The support base 3 is mounted on the limiting frame 2, and the support base 3 is provided with a connecting frame 32;

[0059] Cutting unit 4 is mounted on support base 3 and is used to cut tape body 1;

[0060] The clamping mechanism 5 is mounted on the limiting frame 2 and is used to clamp and limit the tape body 1.

[0061] The limiting frame 2 is also provided with a sleeve 22 for limiting the shaft 21. A positioning pin 23 is threaded between the sleeve 22 and the shaft 21 to ensure the stable installation of the shaft 21 on the limiting frame 2.

[0062] Through the cooperation of the shaft 21, the sleeve 22, and the positioning pin 23, the tape body 1 can be stably set on the limit frame 2 and can rotate smoothly, which is convenient for cutting and use.

[0063] The movable plate 42 is provided with a support rod 44, which is slidably connected to the connecting frame 32 and plays a supporting and guiding role for the movable plate 42.
