It has the functions of sealing and shock absorption, and has excellent sealing, compression deformation resistance, flame retardancy, wettability, etc. The products are widely used in electronic and electrical products, mechanical parts, various small household appliances, mobile phone accessories, industrial instruments, computers and peripheral equipment, auto parts, audio-visual equipment, toys, cosmetics, etc.

[0003] The prior art has the following deficiencies: the existing foam tape has poor protective performance and poor waterproof performance, which may cause water vapor outside the foam tape to enter the interior of the article, affecting the adhesion effect between the foam tape and the article, failing to meet the needs of users, and reducing the practicality of the highly protective foam tape.

[0004] An existing patent (publication number: CN214400347U) discloses a high-protective foam tape, comprising a tape body, a PU foam layer is arranged on the outer surface of the tape body, a substrate layer is arranged on the side of the PU foam layer away from the tape body, and a waterproof layer is arranged on the side of the substrate layer away from the PU foam layer. The advantages of good protective performance and good waterproof performance are achieved by arranging the cooperation of the tape body, the PU foam layer, the substrate layer, the release paper layer, the foam layer, the adhesive paper layer, the waterproof layer, the waterproof coating, the waterproof adhesive layer, the waterproof film layer, the outer layer, the impact-resistant layer, the wear-resistant material layer and the corrosion-resistant layer, thereby solving the problem that the existing foam tape has poor protective performance and poor waterproof performance, which will cause water vapor outside the foam tape to enter the interior of the article, which will affect the adhesion effect of the foam tape and the article, and cannot meet the needs of users, thereby reducing the practicality of the high-protective foam tape.

[0005] However, the above technical solution still has certain defects. In the process of using the foam tape, the foam tape is thicker than the general tape, which makes it difficult to tear the foam tape apart conveniently. Generally, scissors are needed to cut the foam tape at the place where it needs to be cut, which makes the process of using the foam tape too troublesome. Therefore, a highly protective foam tape is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A highly protective foam tape, such as Figures 1 to 4As shown, it comprises a shell 1, the inner wall of the shell 1 is rotatably connected with a rotating shaft 6, the outer wall of the rotating shaft 6 is rolled with a tape body 7, the side wall of the shell 1 is connected with a glue outlet 2, and the inner wall of the glue outlet 2 is provided with a glue cutting mechanism 4;

[0028] The glue cutting mechanism 4 includes two groups of guide bars 401, the two groups of guide bars 401 are fixedly connected to the inner wall of the glue outlet 2, a group of pressing plates 402 are slidably connected between the two groups of guide bars 401 and the glue outlet 2, a cutting knife 403 is slidably connected between the two groups of guide bars 401, and a pushing block 404 extending to the outside of the glue outlet 2 is slidably connected to the top of the cutting knife 403, and two groups of pushing rods 405 are fixedly connected to the side wall of the pushing block 404, and the two groups of pushing rods 405 are respectively abutted against one The side wall of the group pressure plate 402, the pushing block 404 is fixedly connected to an abutment sheet 406 at one end outside the glue outlet 2, the outer wall of the abutment sheet 406 is provided with a rubber coating, and a plurality of anti-slip grooves are provided on the top of the abutment sheet 406. The end of the tape body 7 extends to the outside of the glue outlet 2, and the tape body 7 passes under the two groups of pressure plates 402. The bottom end of the shell 1 is rotatably connected to a pressure roller 3, and a plurality of protrusions are provided on the outer wall of the pressure roller 3. The length of the pressure roller 3 is the same as the width of the tape body 7.

[0029] By pushing the abutment sheet 406, the abutment sheet 406 drives the pushing block 404 to move, and in the process of the pushing block 404 moving, the two sets of pushing rods 405 are driven to move, and the two sets of pushing rods 405 are driven by the pushing block 404 to contact the pressing plate 402, and push the pressing plate 402 to slide downward, so that the two sets of pressing plates 402 press the part of the tape body 7 to be cut, and then as the pushing block 404 continues to move, the bottom end of the pushing block 404 contacts the side wall of the cutting knife 403, so that the pushing block 404 pushes the cutting knife 403 to slide between the two sets of guide strips 401, so that the cutting knife 403 slides on the tape body 7 A V-shaped opening is cut on the top, so that the user can easily tear off the tape body 7 from the V-shaped opening, and the foam tape is thicker than ordinary tape, so that the two ends of the foam tape are easy to be lifted up from the wall when subjected to external friction. By creating a V-shaped opening in the tape body 7 during cutting, the end of the tape is an inclined surface, which is not easily lifted up by external friction. The tape body 7 is pulled out from the inside of the shell 1. After the tape body 7 is pasted to the specified position, the pressure roller 3 is pressed above the tape body 7 to roll the tape body 7, so that the tape body 7 can be more adhered and more firmly.

[0030] Please refer to Figure 3 and Figure 4The side wall of the glue outlet 2 is provided with a cutting mechanism 5, and the cutting mechanism 5 includes two groups of guide rails 501, and the outer walls of the two groups of guide rails 501 are respectively slidably connected with two groups of sliders 502, and a blade 503 is fixedly connected between the two groups of sliders 502 on the same side.

The side wall of the limit pin 504 is fixedly connected with a return spring 506 located inside the slider 502, and the end of the return spring 506 is fixedly connected to the inner wall of the slider 502.

[0031] By pushing the limit pin 504 before use, the limit pin 504 compresses the return spring 506 and slides out from the limit groove 505, and then the slider 502 slides on the outer wall of the guide rail 501, so that the slider 502 drives the blade 503 to move, thereby changing the distance between the two sets of blades 503 and the position of the two sets of blades 503, and then the limit pin 504 is released so that the return spring 506 pushes the limit pin 504 to reset. At this time, the limit pin 504 is inserted into the other set of limit grooves 505, so that the limit grooves 505 block the movement of the limit pin 504, and the blade 503 cannot move at this time. Then, in the process of pulling out the tape body 7, the tape body 7 is cut into thin strips by the blade 503 based on the blade 503, so that when the tape needs to be cut in some special circumstances, the tape body 7 can be quickly cut into thin strips.

[0032] When in use, when the foam tape needs to be cut, the abutment sheet 406 is pushed so that the pushing block 404 pushes the cutting knife 403 and the pushing rod 405 to move respectively, so that the pressing plate 402 presses the tape body 7 to be cut, and the cutting knife 403 cuts the tape body 7, so that a V-shaped notch appears on the tape body 7, so that the user can easily tear off the tape body 7 along the V-shaped notch. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
