Description

Technical Field

[0001] This utility model relates to the field of masking tape technology, and in particular to a masking tape with a lifting edge. Background Technology

[0002] Masking tape is a roll of adhesive tape made primarily from masking paper and pressure-sensitive adhesive. One side is coated with pressure-sensitive adhesive, and the other side is coated with an anti-sticking material. It is commonly known in the industry as masking paper pressure-sensitive adhesive tape. Based on different temperatures, it can be divided into room temperature masking tape, medium temperature masking tape, and high temperature masking tape; based on different adhesion levels, it can be divided into low-tack masking tape, medium-tack masking tape, and high-tack masking tape; and based on different colors, it can be divided into uncolored masking paper and colored masking paper, etc.

[0003] Masking tape with a pull edge is a functional adhesive product with structural optimization based on traditional masking tape. It has a pull edge on one side or a specific position of the tape body, which is made of a different material than the base tape and is not coated with pressure-sensitive adhesive. It is also called a peel edge or tear strip. It is still a sub-type of masking pressure-sensitive adhesive tape. It can ensure the integrity of the base tape and the masking boundary does not shift during the peeling process, avoiding damage to the protected surface or leakage of masking coating due to violent tearing. However, in the existing masking tapes with pull edges, there is local unsealing because the pull edge is not glued. The pull edge only makes physical contact with the object being adhered to, without an adhesive layer. If the surface of the object being adhered to is uneven, it is easy to form a small gap, which can seep into the masking area, resulting in uneven color separation boundary. It is necessary to treat the leakage marks and increase the construction process. Utility Model Content

[0017] 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.

[0018] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a masking tape with a lifting edge, comprising an adhesive tape 1, a lifting mechanism 2 fixedly connected to the outer wall of the adhesive tape 1, the lifting mechanism 2 being used for quick lifting of the tape, and an adjusting mechanism 3 fixedly connected to one side of the outer wall of the adhesive tape 1, the adjusting mechanism 3 being used for connecting the tape; the lifting mechanism 2 includes an adhesive tape edge 201, the adhesive tape edge 201 being fixedly connected to the front and rear sides of the outer wall of the adhesive tape 1, a plurality of cutting holes 202 being opened around the outer wall of the adhesive tape 1, a fixing adhesive 203 being fixedly connected to the inner center of the cutting holes 202, and a fixing ring 204 being fixedly connected to the inner center of the adhesive tape 1, the fixing ring 204 being fixedly connected to the inner center of the adhesive tape 1. An adjusting ring 205 is rotatably connected to one side of the outer wall of the adjusting ring 205. A fixing component 206 is installed in the middle of the inner wall of the adjusting ring 205. The fixing component 206 includes an adjusting rod 2061. The adjusting rod 2061 is slidably connected to the outer wall of the adjusting ring 205. A fixing block 2065 is fixedly connected to each adjacent side of the outer wall of the adjusting rod 2061. A positioning shaft 2062 is rotatably connected to the side of the outer wall of the adjusting rod 2061 that is far away from it. A gear 2063 is rotatably connected to the middle of the inner wall of the adjusting ring 205. A plurality of sliding grooves 2064 are opened in the middle of the inner side of the gear 2063. The fixing block 2065 is slidably connected to the middle of the inner wall of the sliding groove 2064. Specifically, the adhesive edges 201 on the front and back sides of the adhesive tape 1 have weak adhesion, allowing users to quickly pull the tape off the roll by pinching it, avoiding contact with the adhesive surface with their fingers. This solves the problems of traditional masking tape being sticky and difficult to peel off. The adhesive tape 1 has regularly distributed cutting holes 202 around its perimeter, eliminating the need for a knife during cutting; simply tear along the holes to break the tape along a preset path, achieving convenient cutting. The fixing adhesive 203 inside the cutting holes 202 ensures the integrity of the tape before cutting, preventing natural breakage. The fixing ring 204 on the inner wall of the adhesive tape 1 connects to the core of the roll, and the adjusting ring 205 on the outer side can rotate relative to the fixing ring 204. Rotating the adjusting ring 205 will drive the gear 1 2063 to rotate, and its inner side tilts... The inclined or spiral-shaped groove 2064 causes the fixing block 2065 to move along the track, which drives the adjusting rod 2061 to slide on the outer wall of the adjusting ring 205. The positioning shaft 2062 at the end of the adjusting rod 2061 extends and retracts accordingly. When the positioning shaft 2062 extends, it can abut against the inner wall of the external roller or the fixing device, and fix the adhesive tape 203. When retracted, it can adapt to rollers of different diameters, improving versatility. When in use, the user pulls up the adhesive tape 1 through the tape edge 201 and tears it along the cutting hole 202 as needed. When installed on the bracket, the adjusting ring 205 is rotated to extend and retract the positioning shaft 2062 to achieve a stable connection or disassembly. This design takes into account the needs of convenient access, precise cutting and flexible installation of masking tape.

[0019] Reference Figure 1 , Figure 2 and Figure 5 The adjusting mechanism 3 includes a fixed plate 301, which is fixedly connected to one side of the outer wall of the adhesive tape 1. A connecting plate 302 is fixedly connected to the other side of the fixed plate 301. A handle 303 is fixedly connected to the middle of the inner wall of the connecting plate 302. A fixed shaft 304 passes through the other side of the connecting plate 302. A limiting plate 305 is rotatably connected to the right side of the outer wall of the fixed plate 301. The limiting plate 305 is engaged with the fixed shaft 304. A driving assembly 306 is installed in the middle of the inner wall of the fixed plate 301. The driving assembly 306 includes a second gear 3061, which is rotatably connected to the left side of the inner wall of the fixed plate 301. A third gear 3062 is rotatably connected to the right side of the inner wall of the fixed plate 301. The second gear 3061 and the third gear 3062 are meshed. A connecting shaft 3063 is fixedly connected to the front side of the outer wall of the third gear 3062. Specifically, the fixing plate 301 is a fixed base and is connected to the external structure through the connecting plate 302. Rotating the handle 303 can drive the fixing shaft 304 that passes through the connecting plate 302 to rotate. When the fixing shaft 304 engages with the right limit plate 305 of the fixing plate 301, it can lock the relative position of the connecting plate 302 and the fixing plate 301. When the engagement is released, the connection angle or position can be adjusted. The drive assembly 306 on the inner wall of the fixing plate 301 is responsible for power transmission. Gear 2 3061 and gear 3 3062 mesh. When gear 2 3061 is rotated by external force, it drives gear 3 3062 to rotate synchronously. The power is transmitted to the fixing ring 204 through the connecting shaft 3063 on the front side of gear 3 3062, realizing the rotation adjustment or position linkage of the tape roll. It works with the lifting mechanism 2 and the fixing assembly 206 to complete the tape picking, fixing and other operations.

[0020] Reference Figure 1 , Figure 2 and Figure 3 A spring 4 is fixedly connected to the top right side of the fixing plate 301. A limit rod 5 is fixedly connected to one end of the outer wall of the spring 4. A positioning plate 6 is fixedly connected to the right side of the outer wall of the fixing plate 301. Multiple fixing holes 7 are opened around the outer wall of the connecting plate 302. A gasket 8 is fixedly connected to the right side of the inner wall of the fixing plate 301. A spring 9 is fixedly connected to the rear side of the outer wall of the gasket 8. A gear 10 is rotatably connected to the bottom of the outer wall of the fixing ring 204. A bolt 11 passes through the middle of the inner wall of the gear 10. Specifically, the fixing plate 301 serves as the basic load-bearing component. Spring 4 on its top right side provides continuous thrust to the limiting rod 5 through elastic force, allowing the limiting rod 5 to engage with the fixing hole 7 on the connecting plate 302, thus fixing the connecting plate 302 and the fixing plate 301 relative to each other. When it is necessary to adjust their positions, external force pulls the limiting rod 5 to compress the spring 4, disengaging it from the fixing hole 7, thereby adjusting the position of the connecting plate 302. After release, the spring 4 resets, causing the limiting rod 5 to re-engage with the corresponding fixing hole 7 to complete the positioning. The gasket 8 on the inner wall of the fixing plate 301 acts as a buffer... The shock absorption function is achieved by the spring 29 connected to it, which can further absorb the impact of external forces and enhance the structural stability. The gear 4 10 at the bottom of the fixing ring 204 is positioned and rotated by the through bolt 11. When the bolt 11 is tightened, the position of the gear 4 10 is fixed. When it is loosened, the gear 4 10 can rotate freely and mesh with the gear 1 206 for transmission. Together with the adjusting ring 205 and other components, the overall adjustment function of the tape roll is realized. The positioning plate 6 is used to limit the movement range of the connecting plate 302 and prevent it from falling off the fixing plate 301, so as to ensure the operational stability of the entire adjusting mechanism 3.

[0021] Working principle: The adhesive tape 1 has tape edges 201 on the front and back sides. These edges are not sticky or have weak adhesion. Users can directly pinch the tape edges 201 to quickly pull the tape off the roll, avoiding contamination or sticking caused by fingers touching the adhesive surface. This solves the problem of traditional masking tape edges 201 being sticky and difficult to peel off. Multiple cutting holes 202 are regularly distributed around the adhesive tape 1. When cutting the tape, users do not need a knife; they can simply tear along the cutting holes 202 to cut it. The tape breaks along a preset trajectory for easy cutting. The fixing adhesive 203 inside the cutting hole 202 ensures the integrity of the tape before cutting, preventing it from breaking naturally due to the presence of the cutting hole 202. The fixing ring 204 on the inner wall of the adhesive tape 1 is used to connect the roll. The adjusting ring 205 on its outer side can rotate relative to the fixing ring 204. When the adjusting ring 205 is rotated, it will drive the gear 2063 on the inner wall to rotate synchronously. The sliding groove 2064 on the inner side of the gear 2063 is inclined or spiral. The design allows for the following: when gear 2063 rotates, the fixed block 2065, slidably connected within the slide groove 2064, moves along the track of the slide groove 2064, thereby causing the connected adjusting rod 2061 to slide away from the center of the adjusting ring 205. The positioning shaft 2062 at the end of the adjusting rod 2061 extends and retracts with the movement of the adjusting rod 2061. When the positioning shaft 2062 extends outward, it can abut against the inner wall of the external roll or fixing device, stably fixing the entire tape roll to the support. 2. When retracting inward, it can adapt to rolls of different diameters, improving the versatility of the tape. When using it, the user can easily pull up the adhesive tape 1 through the tape edge 201, pull it out to the required length, and then tear it along the cutting hole 202. If the tape roll needs to be installed on the bracket, the adjusting ring 205 can be rotated, and the positioning shaft 2062 can be extended or retracted through the transmission of gear 2063 and slide 2064, so as to achieve a stable connection or disassembly with the bracket, taking into account the needs of convenient access, precise cutting and flexible installation of masking tape. The fixed plate 301 serves as a basic support and connects to the external structure via the connecting plate 302. Rotating the handle 303 drives the fixed shaft 304, which passes through the connecting plate 302, to rotate. When the fixed shaft 304 engages with the limiting plate 305 on the right side of the fixed plate 301, it locks the relative position of the connecting plate 302 and the fixed plate 301. Releasing the engagement allows adjustment of the connection angle or position. The drive assembly 306 on the inner wall of the fixed plate 301 is responsible for power transmission: gears 2 (3061) and 3 (3062) mesh with each other. When gear 2 (3061) rotates under external force, it drives gear 3 (3062) to rotate synchronously. Power is then transmitted to the fixed ring 204 via the connecting shaft 3063 on the front side of gear 3 (3062), enabling rotational adjustment or positional linkage of the tape roll. This, combined with the lifting mechanism 2 and the fixed assembly 206, completes operations such as tape dispensing and fixing. 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.
