Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, and in particular to a high-strength cowhide adhesive tape. Background Technology

[0002] Adhesive tape consists of two parts: a substrate and an adhesive. It connects two or more unconnected objects together by bonding. Its surface is coated with an adhesive. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives. In modern times, various polymers are widely used. Adhesives can stick things together because their molecules form bonds with the molecules of the objects to be connected. These bonds can firmly bind the molecules together. The composition of adhesives varies depending on the brand and type, and there are various polymers. Kraft paper tape is one type of tape.

[0003] Existing kraft paper tapes have a relatively simple structure, and their strength needs to be improved. Otherwise, tape breakage will cause inconvenience to users and unnecessary impacts. Furthermore, existing kraft paper tapes are inconvenient to use. For example, the tear-off end of the tape is difficult to find and easily tear. Some users even use their fingernails or other sharp objects to tear the end, easily damaging the flatness of the tape end, affecting its usability and appearance. In addition, after the tape is used up, the torn end may not be able to be accurately and perfectly repositioned, which may lead to the adhesive end being exposed and thus ineffective, affecting future use and causing waste. To address these issues, we have designed a high-strength kraft paper tape to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength cowhide tape to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-strength cowhide tape includes a tape body and a mounting base. The tape body is wound around the outside of a tape core. The mounting base includes a base plate, a movable support plate, a fixed support plate, and a rotating column. Rotating shafts are symmetrically arranged on the left and right sides of the rotating column. The movable support plate and the fixed support plate are respectively provided with mounting holes for adjacent rotating shafts to be inserted. The rear surface of the fixed support plate is provided with an outer plate in a horizontal direction. The front surface of the outer plate is provided with multiple telescopic columns. The front ends of the multiple telescopic columns are connected to the same movable plate. The lower part of the front surface of the movable plate is provided with an abutment plate. Springs are sleeved on the outside of the telescopic columns. The tape body includes an outermost cowhide layer. A waterproof layer is provided inside the cowhide layer. A fiber mesh layer is provided inside the waterproof layer. A metal wire mesh layer is provided inside the fiber mesh layer. An adhesive layer is provided inside the metal wire mesh layer.

[0007] As a preferred embodiment of this utility model: a slot is provided on the side surface of the outer plate near the movable support plate, and an inner plate is slidably inserted into the slot. The other end of the inner plate is fixedly connected to the rear surface of the movable support plate through a connecting block.

[0008] As a further preferred embodiment of this utility model: the bottom of the movable support plate is provided with a slider, and the top of the base plate is provided with a sliding groove for the slider to slide into. A threaded rod is rotatably provided in the sliding groove. The slider is threadedly sleeved on the outside of the threaded rod. The end of the threaded rod away from the fixed support plate passes through to the outside of the sliding groove and is connected to a knob. The knob is rotatably set on the outer surface of the base plate.

[0009] As a further preferred embodiment of this utility model: the tape core is rotatably sleeved on the outside of the rotating column, the rotating column is rotatably disposed between the movable support plate and the fixed support plate, the movable support plate is slidably disposed on one side of the top of the base plate, and the fixed support plate is fixedly disposed on the other side of the top of the base plate.

[0010] As a further preferred embodiment of this utility model: the movable plate is located behind the rotating column.

[0011] As a further preferred embodiment of this utility model: the length of the abutment plate is equal to the width of the tape body, the abutment plate is inclined, and the bottom of the abutment plate is blade-shaped.

[0012] The beneficial effects of this utility model are as follows: This device has a multi-layer structure, and through the combined effect of the leather layer, fiber mesh layer, and metal wire mesh layer, the strength of the tape body is greatly improved. Specifically, the installation before use is as follows: By rotating the knob, the threaded rod is rotated, which in turn moves the slider along with the movable support plate. This allows adjustment of the distance between the movable support plate and the fixed support plate, thus maximizing the distance between them. At this point, the rotating column can be removed, and the tape core can be fitted onto the outside of the rotating column. Then, the rotating shaft is aligned with the mounting hole, and the distance between the movable support plate and the fixed support plate is minimized, so that the rotating shaft is embedded in the mounting hole, completing the installation of the tape body. Similarly, the disassembly of the tape body is also very simple and convenient, facilitating replacement. When using this device: The pulling end of the tape body starts from the bottom of the rotating column. The tape extends outwards. When the user cannot find the end of the tape or has difficulty tearing it, the device's design incorporates a spring that pushes a moving plate towards the rotating column. This ensures the abutment plate remains in contact with the outer surface of the tape. The user can then rotate the tape until the end of the tape contacts the bottom of the abutment plate. Because the bottom of the abutment plate is blade-shaped, it easily lifts the tear-off end of the tape, making it easy for the user to locate and proceed with subsequent operations. When the tape is no longer in use, the user can rotate it. In this case, the abutment plate cannot lift the tear-off end; instead, it flattens and straightens the tear-off end to prevent the adhesive from being exposed, thus improving the device's usability.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Please see Figure 1-5 In this embodiment of the present invention, a high-strength cowhide tape includes a tape body 1 and a mounting base. The tape body 1 is wound around the outside of the tape core 2. The mounting base includes a base plate 3, a movable support plate 7, a fixed support plate 10, and a rotating column 19. The tape core 2 is rotatably sleeved on the outside of the rotating column 19. The rotating column 19 is rotatably disposed between the movable support plate 7 and the fixed support plate 10. The movable support plate 7 is slidably disposed on one side of the top of the base plate 3, and the fixed support plate 10 is fixedly disposed on the other side of the top of the base plate 3. Rotating shafts 6 are symmetrically provided on the left and right sides of the rotating column 19. Mounting holes 11 are respectively provided on the movable support plate 7 and the fixed support plate 10 for the adjacent rotating shafts 6 to be rotatably embedded.

[0022] The rear surface of the fixed support plate 10 is provided with an outer plate 9 in the horizontal direction. The front surface of the outer plate 9 is provided with a plurality of telescopic columns 17. The front ends of the plurality of telescopic columns 17 are connected to the same movable plate 16. The movable plate 16 is located behind the rotating column 19. The lower part of the front surface of the movable plate 16 is provided with an abutment plate 18 for abutting against the surface of the tape body 1. The length of the abutment plate 18 is equal to the width of the tape body 1. The abutment plate 18 is inclined and the bottom of the abutment plate 18 is blade-shaped. A spring 15 is sleeved on the outside of the telescopic column 17.

[0023] The tape body 1 includes an outermost cowhide layer 14, an inner waterproof layer 23, an inner fiber mesh layer 22, an inner metal wire mesh layer 21, and an adhesive layer 20.

[0024] A slot is provided on the side surface of the outer plate 9 near the movable support plate 7, and the inner plate 8 is slidably inserted into the slot. The other end of the inner plate 8 is fixedly connected to the rear surface of the movable support plate 7 through a connecting block.

[0025] The bottom of the movable support plate 7 is provided with a slider 5, and the top of the base plate 3 is provided with a sliding groove 12 for the slider 5 to slide into. A threaded rod 4 is rotatably provided in the groove 12. The slider 5 is threadedly sleeved on the outside of the threaded rod 4. The end of the threaded rod 4 away from the fixed support plate 10 passes through to the outside of the groove 12 and is connected to a knob 13. The knob 13 is rotatably set on the outer surface of the base plate 3.

[0026] Compared to traditional leather tape, this device features a multi-layered structure. Through the combined action of the leather layer 14, fiber mesh layer 22, and metal wire mesh layer 21, the strength of the tape body 1 is significantly improved. Specifically, the installation process before use involves rotating the knob 13 to rotate the threaded rod 4, which in turn moves the slider 5 along with the movable support plate 7. This allows adjustment of the distance between the movable support plate 7 and the fixed support plate 10, maximizing the gap between them. At this point, the rotating column 19 can be removed, and the tape core 2 can be fitted onto the outside of the rotating column 19. Then, the rotating shaft 6 is aligned with the mounting hole 11, and the distance between the movable support plate 7 and the fixed support plate 10 is minimized, allowing the rotating shaft 6 to embed into the mounting hole 11, completing the installation of the tape body 1. Similarly, disassembling the tape body 1 is also very simple and convenient, facilitating replacement. During use, the pulling end of the tape body 1 is from the rotating... The column 19 extends outwards at its lower end. When the user cannot find the end of the tape or has difficulty tearing it, the structure of this device is designed so that the spring 15 pushes the moving plate 16 towards the rotating column 19, thereby ensuring that the abutment plate 18 is always in contact with the outer surface of the tape body 1. Therefore, the user can rotate the tape body 1 until the end of the tape body 1 contacts the bottom of the abutment plate 18. Since the bottom of the abutment plate 18 is blade-shaped, it can easily lift up the tear-off end of the tape body 1, making it easier for the user to find the tear-off end of the tape body 1 for subsequent operations. When the tape body 1 is finished for one use, the user can rotate the tape body 1. At this time, the abutment plate 18 cannot lift up the tear-off end of the tape body 1. The abutment plate 18 can only flatten and straighten the tear-off end of the tape body 1 to prevent the adhesive at the end from being exposed, which would affect the next use and improve the practicality of the device.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
