However, due to the brittleness of glass fibers, short fibers can easily fall off during the cutting process. These short fibers are harmful to the human body, posing a safety hazard during prolonged fiberglass fabric cutting. Therefore, there is an urgent need to develop a safe fiberglass fabric cutting mechanism. Utility Model Content

[0012] 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.

[0013] Example 1:

[0014] like Figure 1-Figure 5As shown, the utility model discloses a safe cutting mechanism for glass fiber fabric, comprising a frame 1 and a cutting platform 2 arranged on the frame 1, vertical plates 3 are arranged on both sides of the cutting platform 2, a crossbeam 4 is arranged on the top of the vertical plates 3, vertical guide grooves 14 are arranged on the opposite inner sides of the two vertical plates 3, a cutting knife 11 is horizontally placed between the guide grooves 14, the two ends of the cutting knife 11 are slidably connected in the guide grooves 14, a vertical upward guide rod 6 is arranged on the upper end of the cutting knife 11, and a guide rod 6 is arranged on the crossbeam 4 corresponding to the guide rod 6. A guide hole is provided, and the guide rod 6 slides through the guide hole. A first cylinder 5 is provided vertically downward on the crossbeam 4, and the telescopic end of the first cylinder 5 is connected to the cutting knife 11; a first dust hood 12 is provided between the vertical plates 3 on both sides of the cutting knife 11, and the dust suction port of the first dust hood 12 is a long strip structure. The dust suction port of the first dust hood 12 is toward the part that contacts the cutting platform 2 during the downward movement of the cutting knife 11. A dust suction pipe 10 is provided on each first dust hood 12, and the dust suction pipe 10 is connected to the dust suction equipment.

[0015] Under normal circumstances, the glass fiber fabric to be cut is transported from the cutting platform 2 and driven by the corresponding conveying mechanism, such as a cloth winding roller, a pressure roller, etc. In actual work, when the part to be cut moves to the point directly below the cutting knife 11 on the cutting platform 2, it stops moving. At this time, the first cylinder 5 pushes the cutting knife 11 downward in the guide groove 14 to cut the glass fiber fabric. When the cutting knife 11 contacts the cutting platform 2, the glass fiber fabric is cut. The dust collection device is an existing known device, such as a vacuum cleaner. When the cutting knife 11 cuts the glass fiber fabric, the short fibers of the generated glass fiber can be sucked away by the suction force of the first dust hood 12, so that the cutting platform 2 and the end of the cut glass fiber fabric are free of short fibers, and the operator's operation and handling process is also safer. The ends of the cutting blade 11 are slidably connected to the guide groove 14. To ensure stable lifting and lowering, the horizontal cross-section of the guide groove 14 can be rectangular, while the ends of the cutting blade 11 are also rectangular, with corresponding dimensions, to ensure stable lifting and lowering of the cutting blade 11 within the guide groove 14. At the same time, the guide rod 6 on the cutting blade 11 cooperates with the guide hole on the crossbeam 4, further ensuring stable lifting and lowering of the cutting blade 11, thereby improving the cutting accuracy of the glass fiber fabric.

[0016] During the cutting process of the glass fiber fabric, some short fibers are located on the upper surface of the glass fiber fabric, while others are located on the lower surface. Therefore, the first dust hood 12 can only remove the short fibers on the upper surface of the glass fiber fabric during the suction process. The short fibers remaining on the lower surface of the glass fiber fabric cannot be removed. Therefore, during the actual processing process, the cut glass fiber fabric will move forward with the short fibers, causing them to scatter around and pose a certain risk to the operator. Although the amount of short fibers is relatively small in this case, the safety level is still not high enough.

[0017] A hollow area 15 is provided on the cutting platform 2 directly below the cutting knife 11, and the downward projection of the cutting knife 11 is located within the scope of the hollow area 15. Vertical guide columns 7 are provided on the frame 1 on both sides of the hollow area 15, and a lifting platform 8 is slidably connected to the guide columns 7. The upper surface of the lifting platform 8 corresponds to the cutting knife 11, and a second vertically upward cylinder 9 is provided on the frame 1 below the lifting platform 8. The telescopic end of the second cylinder 9 is connected to the lifting platform 8; when the second cylinder 9 drives the lifting platform 8 to move to the top, the upper surface of the lifting platform 8 is flush with the upper surface of the cutting platform 2; second dust suction covers 13 are provided on the lower surface of the cutting platform 2 on both sides of the lifting platform 8. The dust suction port of the second dust suction cover 13 is a long strip structure, and the dust suction port of the second dust suction cover 13 faces the hollow area 15. A dust suction pipe 10 is also provided on the second dust suction cover 13, and the dust suction pipe 10 is connected to the dust suction equipment.

[0018] A hollow area 15 is provided on the cutting platform 2, and a lifting platform 8 is provided below the hollow area 15. The lifting platform 8 is driven by the second cylinder 9 to perform lifting motion. When cutting is required, the lifting platform 8 rises to a level with the cutting platform 2. At this time, the cutting knife 11 descends and cuts the glass fiber fabric in correspondence with the lifting platform 8. Among the short fibers of glass fiber produced in this process, the short fibers located on the upper surface of the glass fiber fabric can be sucked away by the first dust hood 12, while the short fibers located on the lower surface of the glass fiber fabric can be sucked away by the second dust hood 13. In addition, some short fibers located on the upper surface of the lifting platform 8 are sucked away by the second dust hood 13 when the lifting platform 8 passes through the second dust hood 13 during its descent. This allows all the short fibers of glass fiber to be sucked away during the cutting process, thereby ensuring the safety of the operator in subsequent operations on the glass fiber fabric and improving safety.
