Description

Technical Field

[0001] This utility model relates to the field of composite tape technology, specifically a composite tape. Background Technology

[0002] Composite tape is a type of tape product with multiple functions and properties. It refers to tape made by combining two or more materials of different materials or functions through specific processing techniques. These materials typically include a substrate, adhesive, and release paper or release film. Common substrates include plastic films such as polyester film and polypropylene film, fabrics, and foam; adhesives vary depending on the application requirements, using different types of adhesives such as pressure-sensitive adhesives, hot melt adhesives, and rubber-based adhesives; release paper or release film is mainly used to protect the tape's tackiness before use and facilitates storage and processing.

[0003] In the prior art, the patent application number CN202322551182.9 mentions a composite tape that can be easily cut by a cutting component. Therefore, for multi-layer composite tape, it can be easily cut and used even without tools, and the user's hand will not be injured by the cutting blade. However, the above device is a vertical cutting method, and the force required to cut the composite tape is very large, which is very inconvenient to use. Therefore, we propose a composite tape.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A composite adhesive tape includes a base 1, with a mounting frame 2 positioned above the base 1. The base 1 is made of high-strength aluminum alloy, ensuring the stability and durability of the overall structure. The base 1 and the mounting frame 2 are connected by two connecting posts 10, which are threaded for easy installation and disassembly, improving maintenance convenience. The mounting frame 2 has an L-shaped cross-section, which not only enhances its load-bearing capacity but also optimizes the aesthetics of the overall structure. Two side plates 8 are located at the lower end of the mounting frame 2. One side plate 8 is fixedly connected to the lower end of the mounting frame 2 by welding, ensuring a strong connection. A connecting shaft is fixedly connected to the side wall of the side plate 8, and the adhesive tape body 9 is sleeved on the connecting shaft. The other side plate 8 is connected to the mounting frame 2 via a rotating device. The rotating device allows the side plate 8 to rotate flexibly, improving operational convenience. The rotating device includes two rotating shafts mounted on the side wall of the mounting frame 2. The rotating shafts are made of stainless steel, offering good wear resistance and corrosion resistance. Two rotating shafts are mated to the side plates 8 at corresponding positions. The mating joint is precision-machined to ensure smooth rotation. A rotating groove with a depth of 3mm is provided through the side wall of the side plate 8, allowing the connecting shaft to slide smoothly. The other end of the connecting shaft is mated in the rotating groove, and the mating joint uses a snap-fit ​​design to prevent the connecting shaft from falling off during rotation. A limit pin 7 is slidably connected to the upper end of the device frame 2 at the corresponding position, which can effectively limit the position of the side plate 8. A limit groove is provided through the upper end of the side plate 8, which matches the diameter of the limit pin 7 to ensure the accuracy of the limit. The tail end of the limit pin 7 is located in the limit groove, and the tail end is designed with a smooth shape to reduce wear on the side plate 8.

[0020] The device frame 2 includes a pressing plate 3 at its upper part, with a non-slip textured surface for improved user comfort. A cutting device, made of high-hardness alloy steel, is fixedly connected to the lower end of the pressing plate 3, ensuring sharpness and durability. The cutting device includes a moving plate 11 fixedly connected to the lower end of the pressing plate 3. A moving groove runs through the side wall of the device frame 2, providing sufficient space for the moving plate 11 to move. The moving plate 11 slides within the moving groove, using lubricating grease at the sliding connection to reduce friction and improve smoothness. A blade groove runs through the lower end of the moving plate 11, ensuring stable installation. A cutting blade 12, triangular in shape, is fitted into the blade groove for quick cutting of the tape.

[0021] Specifically, a spring-loaded device is slidably connected through the side wall of the pressing plate 3. This spring-loaded device allows the pressing plate 3 to automatically return to its original position after being pressed, improving operational convenience. The spring-loaded device includes two sliding rods 4 slidably connected through the side wall of the pressing plate 3. Both sliding rods 4 are fixedly connected to the side wall of the device frame 2 using bolts for easy disassembly and maintenance. Springs 6 are fitted onto the side wall of each sliding rod 4 located below the pressing plate 3. The springs 6 are made of high-elasticity stainless steel, providing good rebound performance and durability. A pressing groove 5 with a depth of 2mm is provided through the upper end of the pressing plate 3 to facilitate the application of pressing pressure.

[0022] It is worth mentioning that a handle 13 is fixedly connected to the side wall of the device frame 2. The surface of the handle 13 is covered with soft rubber, which improves the comfort and anti-slip properties of the grip.

[0023] In this utility model, after the operator pulls out the limiting pin 7 on one side, he can move the corresponding side plate 8 to open it, pull out the tape body 9 on the connecting shaft for replacement, and after the replacement is completed, let the side plate 8 return to its original position and insert the limiting pin 7 to complete the connection.

[0024] After normal use of the tape body 9, the pressing plate 3 can be lowered by pressing the pressing groove 5 at the corresponding position with your finger. The spring 6 below helps the pressing plate 3 to reset. The pressing plate 3 moves down and can bring the moving plate 11 down. The cutting blade 12 below can contact the side wall of the tape body 9. The triangular blade tip can directly cut the tape, which can quickly cut and reduce the difficulty of cutting.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
