[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model sets multiple longitudinal indentations on the masking paper, and neoprene rubber resin is set in the longitudinal indentations. The neoprene rubber resin has both the elasticity of rubber and the processing characteristics of resin, thereby improving the toughness of the masking paper and enabling it to withstand higher tensile forces; by moving the extension plate up and down, the extension plate moves up and down, driving the rotating plate and the cutter head to move up and down. The cutter head is in close contact with the masking paper, which is conducive to adapting to tape components with different usage levels. The up and down movement of the extension plate drives the sliding plate to move up and down, and the up and down movement of the sliding plate causes the tension spring to undergo elastic deformation and be stretched. When the extension plate is released, the tension spring that has undergone elastic deformation and been stretched returns to its original position, pushing the sliding plate back to its initial position. The sliding plate being pushed back to its initial position causes the extension plate to move back to its initial position, causing the cutter head to return to its initial position. At this time, the vertical support can be rotated, and the rotation of the vertical support drives the rotation of the sliding plate, which in turn drives the rotation of the extension plate, which in turn drives the rotation of the rotating plate and the cutter head on it to rotate. The cutter head rotates to a suitable position to assist in cutting the masking paper, which is conducive to adapting to tapes of different thicknesses;

[0019] 2. By rotating the cutter head, the rotation of the cutter head drives the rotating plate to rotate. The rotation of the rotating plate causes the limiting opening on the rotating plate to move away from the protrusion of the metal spring. When the cutter head is switched, one of the limiting openings of the rotating plate moves to the position of the protrusion of the metal spring, fixing the rotating plate in place. At this time, the switched cutter head can be used to cut the masking paper. This facilitates quick change of cutter head to cut the masking paper, resulting in different textures at the cut.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-9 A high-toughness masking tape with an auxiliary cutting mechanism includes a core 1, and further includes: a tape assembly 2, a damping rotation mechanism 3, a pressing and cutting mechanism 4, and a size adjustment mechanism 5. The tape assembly 2 is disposed on the core 1, the damping rotation mechanism 3 is installed inside the core 1, the pressing and cutting mechanism 4 is installed on the upper side of the damping rotation mechanism 3, and the size adjustment mechanism 5 is installed on the lower side of the damping rotation mechanism 3. The tape assembly 2 includes: masking paper 21, a primer 22, and an adhesive 23. The masking paper 21 is wound around the core 1, and the masking paper 21 has multiple longitudinal indentations 24. The longitudinal indentations 24 contain neoprene rubber resin. The side of the masking paper 21 closest to the core 1 is coated with the primer 22, which can be an acrylic resin. The adhesive 23 is disposed on the side of the primer 22 away from the masking paper 21, and the adhesive 23 can be an acrylic pressure-sensitive adhesive.

[0033] When tape assembly 2 is unfolded for use, the pressing and cutting mechanism 4 is rotated to the appropriate position to cut tape assembly 2. The damping rotation mechanism 3 restricts the rotation of the pressing and cutting mechanism 4. After tape assembly 2 is used up, the size adjustment mechanism 5 adjusts the size and removes the core 1. At this time, new tapes of different sizes can be placed, which is conducive to reuse.

[0034] Multiple longitudinal indentations 24 are provided on the masking tape 21. Neoprene rubber resin is placed in the longitudinal indentations 24. Neoprene rubber resin combines the elasticity of rubber and the processing characteristics of resin, thereby improving the toughness of the masking tape 21 and enabling it to withstand higher tensile forces. The primer 22 can be made of acrylic resin, and the adhesive 23 can be made of acrylic pressure-sensitive adhesive. The primer 22 is used to improve the adhesion of the adhesive 23 on the masking tape 21, ensuring that the adhesive 23 is completely adhered to the primer 22. When the tape is removed, the adhesive 23 falls off completely, avoiding residue.

[0035] The pressing and cutting mechanism 4 includes an extension plate 41, a rotating plate 42, and a cutting head 43. The extension plate 41 is disposed on the upper side of the masking paper 21. The rotating plate 42 is rotatably connected to the lower side of the extension plate 41 via a rotating shaft. Multiple cutting heads 43 are fixedly installed on the side wall of the rotating plate 42. The cutting heads 43 are of different types and can form different cutting patterns when cutting the masking paper 21. Multiple limiting holes 44 are provided on the rotating plate 42, and irregular grooves 45 are provided on the extension plate 41.

[0036] Tear the masking tape 21 off the core 1 and unfold it. Move the unfolded part of the masking tape 21 to the cutter head 43. The cutter head 43 acts as a support to cut the masking tape 21.

[0037] The pressing and cutting mechanism 4 further includes a limiting component, which is installed on the upper side of the extension plate 41.

[0038] The limiting component includes a metal spring 46 and fixing screws 47. The metal spring 46 is disposed in the irregular slot 45. The two fixing screws 47 pass through the front and rear sides of the metal spring 46 and are threaded to the extension plate 41. A protrusion 48 is provided on the middle side of the metal spring 46, and the protrusion 48 is disposed in the limiting opening 44.

[0039] When the cutter head 43 needs to be replaced, rotate the cutter head 43. The rotation of the cutter head 43 drives the rotating plate 42 to rotate. The rotation of the rotating plate 42 causes the limiting opening 44 on the rotating plate 42 to move away from the protrusion 48 of the metal spring 46. When the cutter head 43 is switched, one of the limiting openings 44 of the rotating plate 42 moves to the position of the protrusion 48 of the metal spring 46, fixing the rotating plate 42 in a limited position. At this time, the switched cutter head 43 can be used to cut the masking paper 21. This facilitates the quick replacement of the cutter head 43 to cut the masking paper 21, resulting in different textures at the cut.

[0040] Example 2: In some embodiments, such as Figures 1-9 In a preferred embodiment of the present invention, the limiting component further includes an elastic pressing component, which is mounted on the extension plate 41. The elastic pressing component includes a sliding plate 49 and a tension spring 410. The upper side of the sliding plate 49 is fixedly mounted on the front side of the extension plate 41. One end of the tension spring 410 is fixedly connected to the lower side of the sliding plate 49, and the other end of the tension spring 410 is fixedly connected to the damping rotation mechanism 3.

[0041] The damping rotation mechanism 3 includes: an upper arc frame 31, a circular support plate 32, and a vertical bracket 33. The upper arc frame 31 is disposed on the upper side inside the core 1. The circular support plate 32 is fixedly installed on the front side of the upper arc frame 31. The vertical bracket 33 is rotatably connected to the middle side of the circular support plate 32 via a rotating shaft. Multiple circular slots 34 are arranged in a circular array with the center of the circular support plate 32 as the center. A strip-shaped opening 35 is provided on the lower side of the circular support plate 32.

[0042] The extension plate 41 moves up and down, which in turn drives the rotating plate 42 and the cutter head 43 to move up and down. The cutter head 43 is in close contact with the masking tape 21, which is beneficial for adapting to tape components 2 with different usage levels. The up and down movement of the extension plate 41 drives the sliding plate 49 to move up and down. The up and down movement of the sliding plate 49 causes the tension spring 410 to undergo elastic deformation and be stretched. When the extension plate 41 is released, the stretched tension spring 410 returns to its original position and pushes the sliding plate 49 back to its initial position. The sliding plate 49 pushes back to its initial position, which causes the extension plate 41 to move back to its initial position, and the cutter head 43 returns to its initial position. At this time, the vertical support 33 can be rotated. The rotation of the vertical support 33 drives the sliding plate 49 to rotate, which in turn drives the extension plate 41 to rotate. The rotation of the extension plate 41 drives the rotating plate 42 and the cutter head 43 on it to rotate. The cutter head 43 rotates to a suitable position to assist in cutting the masking tape 21.

[0043] The sliding plate 49 is slidably connected to the upper arc frame 31, and the other end of the tension spring 410 is fixedly connected to the upper side of the vertical support 33 of the damping rotation mechanism 3.

[0044] The damping rotation mechanism 3 further includes a rotation assembly mounted on a vertical support 33. The rotation assembly includes a fixed base 36, a sliding rod 37, a round head 38, a first magnet 39, and a second magnet 310. The fixed base 36 is fixedly mounted on the rear side wall of the vertical support 33. The sliding rod 37 is slidably connected to the end of the fixed base 36 away from the vertical support 33. The round head 38 is fixedly mounted on the end of the sliding rod 37 away from the fixed base 36. The first magnet 39 is fixedly mounted inside the fixed base 36. The second magnet 310 is fixedly mounted on the end of the sliding rod 37 located inside the fixed base 36. The first magnet 39 and the second magnet 310 repel each other. The round head 38 is disposed in a circular slot 34.

[0045] The rotation of the vertical support 33 drives the fixed seat 36 of the rotating component to rotate, the rotation of the fixed seat 36 drives the sliding rod 37 to rotate, the rotation of the sliding rod 37 drives the round head 38 to rotate, and the round head 38 rotates away from the circular slot 34 and enters the next circular slot 34, so that the rotation of the vertical support 33 produces a damping and limiting effect, and so that the blade 43 of the pressing and cutting mechanism 4 produces a damping and limiting effect when rotating and adjusting.

[0046] The size adjustment mechanism 5 includes a lower arc frame 51 and an adjusting screw 52. The lower arc frame 51 is disposed inside the lower side of the core 1. The lower arc frame 51 is slidably connected to the lower side of the circular support plate 32. The adjusting screw 52 is threadedly connected to the circular support plate 32. The lower arc frame 51 is threadedly connected to the end of the adjusting screw 52 away from the circular support plate 32.

[0047] When the masking tape 21 is used up, loosen the adjusting screw 52 of the size adjustment mechanism 5, remove the lower arc frame 51 from the circular support plate 32, pull out the core 1 from the upper arc frame 31, and replace it with a new core 1 on the upper arc frame 31. If the size of the new core 1 is the same as the size of the old core 1, simply put the lower arc frame 51 and the adjusting screw 52 back into their initial positions. If the size of the new core 1 is different from the size of the old core 1 and is larger than the old core 1, unscrew the adjusting screw 52, ​​move the lower arc frame 51 downwards to a suitable position, and after the adjusting screw 52 passes through the strip opening 35, it is threaded onto the lower arc frame 51 to quickly fix the new core 1.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
