[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] like Figure 1As shown, a waterproof foam tape includes a tape 1 and a bracket 2. The tape 1 is installed on the bracket 2 and is unwound from the bracket 2. The tape 1 can be pasted on electronic products and has waterproof, flame retardant and buffering effects, thereby protecting the electronic products from being affected by water immersion, high temperature, burning and collision. The bracket 2 can unwind the tape 1, calculate the unwinding length of the tape 1, and cut the tape 1, thereby improving the pasting accuracy of the tape 1 and better protecting the electronic products.

[0020] like Figure 2 As shown, the tape 1 includes a foam layer 15, a flame retardant layer 14, a waterproof layer 13, a first adhesive layer 16, a second adhesive layer 12 and a release film layer 11. The first adhesive layer 16 is coated on the bottom of the foam layer 15, the flame retardant layer 14 is compounded on the upper end of the foam layer 15, the waterproof layer 13 is compounded on the upper end of the flame retardant layer 14, the second adhesive layer 12 is coated on the upper end of the waterproof layer 13, and the release film layer 11 is coated on the upper end of the second adhesive layer 12. The flame retardant layer 14 is a polyurethane Pu layer, and a tiny individual bubble structure is arranged inside the flame retardant layer 14. By arranging the tiny bubble structure inside the flame retardant layer 14, the absorption of impact force can be increased and the toughness of the foam tape can be enhanced. The waterproof layer 13 can make the foam tape have better waterproof performance. The release film layer 11 is used to protect the second adhesive layer 12. The above-mentioned foam tape can be adhered to the equipment through the second adhesive layer 12 and the first adhesive layer 16 to protect the equipment and prevent the equipment from being severely bumped and damaged.

[0021] Please combine Figure 1 、 Figure 3 、 Figure 4 As shown, the bracket 2 includes a tape sleeve 21, a sleeve bracket 22, a metering structure 23 and a cutting knife 24. The tape 1 is installed on the tape sleeve 21. The sleeve bracket 22 can be rotatably set on the tape sleeve 21. The metering structure 23 and the cutting knife 24 are installed on the sleeve bracket 22. The metering structure 23 can calculate the unwinding length of the tape 1, and the cutting length 24 can cut the tape 1.

[0022] Specifically, the metering structure 23 includes an encoder 231, a pressure roller 232 and a display screen 233. The pressure roller 232 is installed on the sleeve bracket 22. The encoder 231 is connected to the pressure roller 232. A guide plate 222 is provided on the sleeve bracket 22. The guide plate 222 is fixed on the sleeve bracket 22 and is located below the pressure roller 232. The end of the tape 1 can be placed on the guide plate 222. The pressure roller 232 presses the tape 1 tightly against the guide plate 222, so that the encoder 231 can accurately measure the unwinding length of the tape 1. At the same time, by setting the guide plate 222, the end of the tape 1 is separated from the tape roll, and the end of the tape 1 can be quickly clamped to pull the end of the tape 1 for unwinding. The display screen 233 is installed on the upper end surface of the sleeve bracket 22 for displaying the unwinding length of the tape 1.

[0023] Specifically, the tape sleeve 21 is provided with fixed protruding rings 211, which are arranged at both ends of the tape sleeve 21 to prevent deviation of the tape roll during unwinding and improve the recognition accuracy of the meter-counting structure 23. The tape sleeve 21 is provided with a clamping slot 212, and the sleeve bracket 22 is provided with a clamping ring 221. The clamping ring 221 is clamped in the clamping slot 212, thereby installing the sleeve bracket 22 into the tape sleeve 21. The clamping ring 221 can freely rotate through the clamping slot 212, so that the sleeve bracket 22 rotates as the tape 1 is unwound. The tape sleeve 21 is provided with an arc-shaped protrusion 213, which is arranged near the clamping slot 212 and can quickly guide the clamping ring 221 to clamp into the clamping slot 212.

[0024] The above-described embodiments are merely preferred examples of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features, and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
