[0032] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0033] See also Figure 1-Figure 7 As shown, the present embodiment aims to provide a guide device for a light-shielding material cutting machine, comprising a bearing plate 1, on which a guide portion 2 and a material portion 4 for placing light-shielding tape are fixedly provided, and a cutting portion 3 for adjusting the cutting width of the light-shielding tape is slidably provided on the guide portion 2;

[0034] The guide portion 2 includes a straight guide rail 21 , one end of which is horizontally rotated to be provided with an inclined guide rail 22 , and the inclined guide rail 22 is used for beveling and can adjust the beveling angle.

[0035] In electronic product screens, beveled shading tape can better fit the edges of the screen, reducing light leakage and reflection, which helps improve the screen's display effect, making the image clearer and more vivid, and reducing glare. Beveled shading tape can more precisely control the propagation path and range of light.

[0036] First fixed blocks 26 are fixedly provided at the upper and lower ends of the side walls of the straight guide rail 21, and second fixed blocks 27 are fixedly provided at the upper and lower ends of the side walls of the inclined guide rail 22. A fixed shaft 23 is provided between the straight guide rail 21 and the inclined guide rail 22. The first fixed block 26 is fixed on the fixed shaft 23, and the second fixed block 27 is rotatably provided on the fixed shaft 23, so that the inclined guide rail 22 is rotatably provided on the fixed shaft 23, and then the bevel cutting angle can be adjusted according to the cutting requirements of the shading material, and force is required to achieve rotation.

[0037] The inclined guide rail 22 shares the same structure as the straight guide rail 21, but features a unique tilt angle. It is similarly constructed from high-quality materials such as steel or aluminum to ensure sufficient hardness and rigidity. The design of the inclined guide rail 22 allows for horizontal rotation at one end to connect with the straight guide rail 21, enabling adjustment of the bevel angle. This allows the inclined guide rail 22 to precisely guide the beveling process of the shading material, ensuring accuracy and stability. By adjusting the bevel angle, the light-blocking effect of the shading tape can be flexibly adjusted to meet diverse optical design requirements.

[0038] The straight guide rail 21 includes a first guide rail 212 and a second guide rail 213. The side wall of the second guide rail 213 is provided with a groove, and a screw 25 is threaded through the groove. The side wall of the first guide rail 212 is fixed with a protrusion, which is inserted into the groove. The screw 25 inserts the first guide rail 212 into the groove, thereby inserting the first guide rail 212 on the second guide rail 213. The spacing between the first guide rail 212 and the second guide rail 213 can be adjusted by adjusting the tightening degree of the screw 25 to meet the cutting requirements of light-shielding tapes of different thicknesses. The change in spacing will directly affect the sliding resistance and friction of the cutting part 3 on the guide rail, thereby controlling the forward speed of the cutting part. When the spacing is large, the cutting force is weakened, and vice versa. Appropriate cutting force can ensure that the light-shielding tape is cut evenly and flatly, avoiding quality problems caused by cutting too deep or too shallow.

[0039] Both the straight guide rail 21 and the oblique guide rail 22 are penetrated by a through slot 211, and the side wall of the through slot 211 is provided with a plurality of rotating slots, in which a guide roller 24 is rotatably installed. A motor is fixedly installed on the straight guide rail 21, and the output shaft of the motor is connected to the center of the second guide roller 24 in the entrance of the through slot 211, driving the guide roller 24 to rotate to drive the cutting part 3 to move, and the guide roller 24 rotates from the straight guide rail 21 to the oblique guide rail 22.

[0040] The cutting portion 3 includes a slide plate 31 slidably mounted in the through groove 211, and the through groove 211 at the connection between the oblique guide rail 22 and the straight guide rail 21 has a larger diameter. When the slide plate 31 moves from the straight guide rail 21 to the oblique guide rail 22, the enlarged portion of the through groove 211 provides sufficient space so that the slide plate 31 can move unhindered following the new direction of the oblique guide rail 22, ensuring the continuity and stability of the slide plate 31 during the bevel cutting process and avoiding movement jams or errors caused by angle changes.

[0041] A sliding groove is provided in the skateboard 31, and a connecting rod 34 is slidably installed in the skateboard 31. The connecting rod 34 is slidably installed in the sliding groove. One end of the connecting rod 34 is fixedly connected to a protective shell 35, and the connecting rod 34 is located above the center of the side wall of the protective shell 35. A tool 36 is rotatably set in the protective shell 35.

[0042] A limiting groove 341 is provided at one end of the connecting rod 34, and a screw 32 is rotatably installed in the limiting groove 341. A limiting block is provided at one end of the screw 32, and the diameter of the limiting block is larger than the diameter of the screw 32. The limiting block is rotatably installed in the limiting groove 341, and the screw 32 is threadedly installed on the slide 31. The distance between the tool 36 and the side wall of the guide rail is adjusted by adjusting the tightening degree of the screw 32, so that the shading tape of appropriate width can be cut according to needs.

[0043] A power source 33 is fixedly provided through the slide plate 31 . The power source 33 is preferably a micro motor. The output shaft of the power source 33 is connected to the center of the tool 36 .

[0044] The material part 4 includes a fixed block fixed on the load-bearing plate 1, in which a support block is slidably installed. After adjusting to an appropriate position, the fixed block is fixed by screws. A light-shielding tape is fixed on the side wall of the support block, and the position of the light-shielding tape is adjusted according to cutting requirements.

[0045] When the present invention is used in practice, the shading tape is fixed to the material part 4, and the first guide rail 212 is inserted and arranged on one side of the second guide rail 213 according to the thickness of the shading tape. The spacing is adjusted by adjusting the tightness of the screw 25, so as to control the cutting force to cut the shading tape evenly and smoothly. According to the requirements of bevel cutting, the inclined guide rail 22 is horizontally rotated to a suitable bevel cutting angle, and the spacing between the connecting rod 34 and the side wall of the slide 31 is adjusted by adjusting the tightness of the screw 32, thereby adjusting the spacing between the tool 36 and the side wall of the slide 31 to adapt to shading tapes with different cutting width requirements. The slide 31 is slidably installed in the through groove 211, and the motor is driven. The guide roller 24 rotates to drive the slide 31 to move from the straight guide rail 21 to the inclined guide rail 22, thereby driving the connecting rod 34 to move. Since the tool 36 is fixedly installed on the connecting rod 34, the tool 36 also moves accordingly. During this process, the tool 36 is driven to rotate by the power source 33 to achieve cutting.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
