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.

[0030] Reference Figures 1-5 One embodiment provided by this utility model:

[0031] An electronic tape that is not easily affected by moisture includes a tape core 1 and a tape head finding mechanism 4. A slot 2 is provided on the inner wall of the tape core 1 near the front end. A tape body 3 is wound around the outer end of the tape core 1. The tape body 3 includes a protective coating 301, an antistatic layer 302 is provided at the lower end of the protective coating 301, a moisture-proof layer 303 is provided at the lower end of the antistatic layer 302, and an adhesive layer 304 is provided at the lower end of the moisture-proof layer 303. The protective coating 301 is made of fluoropolymer, the antistatic layer 302 is made of polypropylene doped with carbon black, the moisture-proof layer 303 is made of polyvinyl alcohol film, and the adhesive layer 304 is made of silicone pressure-sensitive adhesive. The protective coating 301, the antistatic layer 302, the moisture-proof layer 303, and the adhesive layer 304 are all bonded together with epoxy resin adhesive.

[0032] Specifically, the protective coating 301 of the tape body 3 is made of fluoropolymer, giving it high chemical resistance and the ability to resist the erosion of various chemicals, ensuring stable tape performance. The antistatic layer 302 is made of polypropylene doped with carbon black, effectively reducing static electricity accumulation and preventing ESD damage to sensitive electronic components, thus improving safety. The moisture-proof layer 303 is made of polyvinyl alcohol film, which effectively blocks moisture penetration, protecting internal electronic components from moisture and extending service life. The adhesive layer 304 is made of silicone pressure-sensitive adhesive, which has excellent adhesion properties, ensuring that the tape adheres well to various surfaces during application and is not easily peeled off. In addition, the protective coating 301, antistatic layer 302, moisture-proof layer 303, and adhesive layer 304 are all bonded together with epoxy resin adhesive, ensuring that each layer is firmly bonded and not easily delaminated or peeled off, thereby increasing overall durability.

[0033] Reference Figures 6-8 The tape head finding mechanism 4 includes a fixed column 401, a fixed plate 402 fixedly mounted at the rear end of the fixed column 401, an installation groove 403 opened at the upper front end of the fixed plate 402, a telescopic rod 404 fixedly mounted inside the installation groove 403, a first spring 406 sleeved on the outer side of the inner rod of the telescopic rod 404, a scraper 405 fixedly mounted at the upper end of the telescopic rod 404, and placement grooves 407 opened on both sides of the front end of the fixed column 401, with second springs installed inside the two placement grooves 407. 408, two second springs 408 are fixedly provided with locking posts 409 on opposite sides, and two locking posts 409 are fixedly provided with toggle blocks 410 at their front ends. The fixing post 401 is placed inside the tape core 1, the fixing plate 402 is located behind the tape core 1, the lower end of the scraper 405 is fixedly connected to the first spring 406, the lower end of the scraper 405 is in contact with the outer surface of the tape body 3, the two toggle blocks 410 pass through the two placement slots 407, and the two locking posts 409 are movably arranged inside the slot 2.

[0034] Specifically, when locating the tape head, rotating the tape roll core 1 causes the locking pin 409 to rotate within the locking groove 2. Because the scraper 405 has a first spring 406 and a telescopic rod 404 at its lower end, the scraper 405 can continuously contact the outer surface of the tape body 3 and push the tape head up, eliminating the need for manual searching. This significantly improves ease of use and saves time. After the tape is used up, the user simultaneously moves the two levers 410, causing the two locking pins 409 to exit from the locking groove 2 and move into the placement groove 407. When the two locking pins 409 are close together, the user can easily remove the fixing pin 401 from the tape roll core 1 and install it into a new tape roll core 1. This design simplifies the tape replacement process and reduces operational difficulty. The scraper 405 has an arc-shaped design, which prevents the tape from being too thick or having an uneven surface.

[0035] Working principle: The protective coating 301 of the tape body 3 is made of fluoropolymer, which can resist the corrosion of various chemicals. The antistatic layer 302 is made of polypropylene doped with carbon black, which effectively reduces static electricity accumulation. The moisture-proof layer 303 is made of polyvinyl alcohol film, which can effectively block moisture penetration. The adhesive layer 304 is made of silicone pressure-sensitive adhesive, which has excellent adhesion performance. In addition, the protective coating 301, antistatic layer 302, moisture-proof layer 303 and adhesive layer 304 are all bonded with epoxy resin adhesive to ensure that each layer is firmly bonded and not easily delaminated or peeled.

[0036] Secondly, when searching for the tape head, rotate the tape roll core 1. The locking pin 409 will rotate in the locking groove 2. Since the scraper 405 has a first spring 406 and a telescopic rod 404 at its lower end, the scraper 405 can continuously contact the outer surface of the tape body 3 and push the tape head up. After the tape is used up, the user simultaneously moves the two levers 410, and the two locking pins 409 will exit from the locking groove 2 and move into the placement groove 407. When the two locking pins 409 are close together, the user can easily remove the fixing pin 401 from the tape roll core 1 and install it in the new tape roll core 1. The scraper 405 has an arc-shaped design, which can prevent the tape from being too thick or the surface from being uneven.

[0037] 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.
