Description

Technical Field

[0001] The utility model relates to the technical field of masking paper, in particular to a masking paper tape with high toughness. Background Art

[0002] Masking paper is a kind of high-tech decorative and spraying paper (also known as color separation tape paper due to its special performance in use), which is widely used in indoor decoration, painting of household appliances and spraying of high-grade luxury cars.

[0003] Patent No. CN202321306303.7 discloses a masking paper tape with high toughness, which relates to the technical field of masking paper tape. In order to solve the problems that in the existing masking paper tape, the solvent flows out from the inside of the wrapping layer to the surface of the bonded object for adhesion, but the solution inside the tape will solidify after a long time without use, and the built-in solution will affect the overall structural strength of the tape,

[0004] Although the above-mentioned patent tears adjacent two masking paper tapes through the tape tearing opening during use, so that the hook surface of the magic tape is separated from the loop surface of the magic tape, and the masking paper tape reinforces the edge position of the tape through the internal plastic tape, so that the edge position of the masking paper tape is not easy to wrinkle and break, thereby improving the toughness of the tape. The masking paper tape can increase the toughness and tensile resistance of the masking paper tape through the external wrinkle texture layer, reducing the risk of tape breakage. However, in the actual use process, since the rolled masking paper is not used up at one time, during the placement process, the free end of the masking paper is prone to warping. After warping, the adhesive layer on its inner wall will be contaminated, and the warped end needs to be torn off during subsequent use, resulting in waste. Therefore, there is an urgent need for a masking paper tape with high toughness to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a masking paper tape with high toughness.

[0006] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0007] A masking paper tape with high toughness includes a carrier ring, on the outer side of which masking paper is wound. A pressing component is installed on the inner wall of the carrier ring, and the pressing component is composed of a guide groove, a guide block, a carrier block, a locking bolt, a connecting frame, a concave cavity, a telescopic column, a spring, a slider and a pressing roller.

[0008] Preferably, one end of the masking paper is fixed on the carrier ring, and an adhesive layer is applied on the inner wall of the masking paper.

[0009] Preferably, the carrier ring is made of plastic, the guide groove is formed on the inner wall of the carrier ring, the guide block is slidably connected with the guide groove, and the guide block is of an arc-shaped structure.

[0010] Preferably, the bearing block is fixed on the surface of the guiding block, and the locking bolt is threadedly connected to both the bearing block and the guiding block.

[0011] Preferably, the connecting frames are symmetrically fixed at both ends of the bearing block. The connecting frames are of an L-shaped structure, and the concave cavity is formed on the connecting frames.

[0012] Preferably, the fixed part of the telescopic column is connected to the bottom end of the concave cavity by screws, and the spring is welded on the outer side wall of the telescopic column.

[0013] Preferably, the movable end of the telescopic column is connected to the slider by screws. The slider matches the specifications of the concave cavity and is slidably connected to the concave cavity. The pressing roller is rotatably installed between the sliders.

[0014] The beneficial technical effects of the present utility model are as follows:

[0015] By designing a pressing mechanism composed of a guiding groove, a guiding block, a locking bolt, a telescopic column, a spring, and a pressing roller, during the use of the masking tape, the combination of the telescopic column and the spring can keep the pressing roller in contact with the surface of the masking tape all the time. Furthermore, the position of the pressing roller can be adjusted to its position by sliding the guiding block in the guiding groove according to the position of the free end of the masking tape, and the adjusted position can be fixed by the locking bolt. The free end of the masking tape is pressed by the pressing roller, which can effectively prevent the phenomenon of edge warping, thereby avoiding waste and ensuring its use effect.

[0022] To make the technical solutions of the present invention clearer and more definite to those skilled in the art, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings, but the implementation manners of the present invention are not limited thereto.

[0023] As Figures 1 - 4 shown, a masking paper 2 tape with high toughness provided in this embodiment includes a carrying ring 1, the masking paper 2 is wound around the outside of the carrying ring 1, and a pressing assembly 3 is installed on the inner wall of the carrying ring 1. The pressing assembly 3 is composed of a guide groove 303, a guide block 304, a carrying block 305, a locking bolt 306, a connecting frame 301, a concave cavity 307, a telescopic column 309, a spring 310, a slide block 308 and a pressing roller 302.

[0024] One end of the masking paper 2 is fixed on the carrying ring 1, and an adhesive layer is applied on the inner wall of the masking paper 2. The adhesive layer can bond the masking paper 2 to the article to be used. The material and structure of the masking paper 2 are the same as those of the masking paper 2 used in the comparative patent.

[0025] The material of the carrying ring 1 is plastic. The guide groove 303 is formed on the inner wall of the carrying ring 1. The guide block 304 is slidably connected to the guide groove 303. The guide block 304 is an arc-shaped structure and can slide in the guide groove 303.

[0026] The carrying block 305 is fixed on the surface of the guide block 304. The locking bolt 306 is threadedly connected to both the carrying block 305 and the guide block 304. The locking bolt 306 can fix the position of the guide block 304.

[0027] The connecting frames 301 are symmetrically fixed at both ends of the carrying block 305. The connecting frames 301 are L-shaped structures. The concave cavity 307 is formed on the connecting frames 301. The concave cavity 307 provides an installation space for the telescopic column 309 and the spring 310.

[0028] The fixed part of the telescopic column 309 is connected to the bottom end of the concave cavity 307 by screws. The spring 310 is welded on the outer side wall of the telescopic column 309. In the initial state, the telescopic column 309 and the spring 310 are in a stretched state. As the masking paper 2 is used, the telescopic column 309 and the spring 310 retract.

[0029] The movable end of the telescopic column 309 is connected to the slider 308 by screws. The slider 308 matches the specifications of the concave cavity 307 and is slidably connected to the concave cavity 307. The pressing roller 302 is rotatably installed between the sliders 308. The pressing roller 302 can always be in contact with the surface of the masking paper 2, so as to press and fix its free end, avoiding the phenomenon of warping.

[0030] The working principle of this device: During use, the masking paper 2 is adhered to the item to be used through the adhesive layer. When the use is completed, since the telescopic column 309 is combined with the spring 310, the pressing roller 302 can always be in contact with the surface of the masking paper 2. Then, according to the position of the free end of the masking paper 2, the pressing roller 302 can be adjusted to its position by sliding the guide block 304 in the guide groove 303, and the adjusted position is fixed by the locking bolt 306. The free end of the masking paper 2 is pressed by the pressing roller 302, which can effectively prevent the phenomenon of warping, thus avoiding waste and ensuring its use effect.

[0031] The above are only further embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent substitutions or changes, all belong to the protection scope of the present utility model.
