Detailed Implementation

[0022] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] The embodiments provided by this utility model are as follows: Figures 1-4 As shown, an easy-tear double-sided tape includes a take-up reel 10 with a double-sided tape 20 wound around it. The double-sided tape 20 includes a release layer 21, an adhesive layer 22, and a tear layer 23. The release layer 21 is attached to the adhesive layer 22 and completely covers the upper surface of the adhesive layer 22. One end of the adhesive layer 22 is fixed to the take-up reel 10. The tear layer 23 includes a fixing part 231 and two rotating parts 232. The fixing part 231 is fixedly disposed on the release layer 21, and the two rotating parts 232 are fixedly disposed on the release layer 21. The moving part 232 is connected to the left and right sides of the fixed part 231 respectively, and rotates around the connection point. Multiple first tear lines 30 are fixedly provided on the release layer 21 along the length direction. Multiple second tear lines 40 are fixedly provided on the adhesive layer 22 along the length direction. Multiple third tear lines 50 are fixedly provided on the tear layer 23 along the length direction. The third tear lines 50 are provided on the fixed part 231 and the rotating part 232, and their number and position correspond to the first tear lines 30.

[0024] Preferably, the number and position of the second tear lines 40 correspond to the first tear lines 30.

[0025] The user pulls out one end of the double-sided tape 20, determines the required length of the double-sided tape 20 according to the needs of use, and then selects the corresponding first tear line 30. With one hand, the user holds down the release layer 21 and the tear layer 23 of the lower double-sided tape 20, and with the other hand, tears the double-sided tape 20 from the side along the first tear line 30, tearing it into one or more tear units. Since the user holds down the tear layer 23 of the lower double-sided tape, the rotating part 232 of the lower tear layer 23 will not be lifted. Then, the user sticks the tear unit to the area of ​​use, selects the rotating part 232 on one side according to convenience, and pulls the rotating part 232 upward to separate the release layer 21 from the adhesive layer 22.

[0026] It should be noted that the first tear line 30, the second tear line 40, and the third tear line 50 selected at this time are on the same vertical plane. Tearing off the first tear line 30 means tearing off the second tear line 40 and the third tear line 50 at the same time.

[0027] Preferably, the adhesive layer 22 includes a substrate layer 221, a first adhesive layer 222 and a second adhesive layer 223. The first adhesive layer 222 is adhered to the upper surface of the substrate layer 221, the second adhesive layer 223 is adhered to the lower surface of the substrate layer 221, and the release layer 21 is attached to the first adhesive layer 222.

[0028] Preferably, the first tear line 30 is evenly distributed on the release layer 21, and the second tear line 40 is evenly distributed on the adhesive layer 22. This arrangement allows for the cutting of tape of the same or multiple lengths, making it convenient to use.

[0029] Preferably, the first tear line 30 has a first notch 60 at both ends, so that the user can tear the first tear line 30 along the first notch 60, making the operation more convenient.

[0030] Preferably, the second tear line 40 has a second notch 70 at both ends, so that the user can tear the second tear line 40 along the second notch 70, making the operation more convenient.

[0031] Preferably, the upper surface of the release layer 21 is provided with several scale lines, and the user can judge the length of the double-sided tape 20 according to the numbers on the scale lines and tear the double-sided tape 20 as needed.

[0032] Preferably, the width of the release layer 21 is greater than the width of the adhesive layer 22, so that the user can peel off the release layer 21 along the side when necessary, providing more ways to remove the release layer 21.

[0033] Preferably, the winding roller 10 has a through hole 80 at its center for fingers to pass through. This design provides more ways to place the double-sided tape when it is not in use, and allows users to pass their fingers through the through hole 80 when using the double-sided tape, making it convenient for them to tear the double-sided tape 20.

[0034] The easy-tear double-sided adhesive of this utility model has a tear-off layer 23 on the release layer 21. The tear-off layer 23 includes a fixing part 231 and two rotating parts 232. The fixing part 231 is fixedly disposed on the release layer 21, and the two rotating parts 232 are respectively connected to the left and right sides of the fixing part 231 and rotate about the connection point as the axis. This allows the user to easily separate the release layer 21 from the adhesive layer 22 after the double-sided adhesive is pasted to the use area, which facilitates the use of the double-sided adhesive.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
