To improve cutting accuracy, a vacuum system is installed to extract air from the fabric on the conveyor belt, making the fabric more compact and improving cutting precision. During vacuuming, the extracted air is discharged through an exhaust pipe. However, the exhaust pipe main of the existing vacuum system for cutting tables has the drawback of poor noise reduction. Utility Model Content
[0003] This invention provides an exhaust manifold structure for a cutting bed vacuum system capable of noise reduction, solving the problem of poor noise reduction effect of the cutting bed's exhaust manifold.
[0004] The above technical problems are solved by the following technical solution: a main exhaust pipe structure for a cutting bed vacuum system, comprising a main exhaust pipe, characterized in that the main exhaust pipe includes an inlet section and an outlet section, the outlet section includes an outlet section end ring, an outlet section outer pipe, and an outlet section inner pipe passing through the outlet section outer pipe, an outlet section filling channel is formed between the outlet section outer pipe and the outlet section inner pipe, the outlet section filling channel is filled with outlet section suction cotton, the outlet section inner pipe is provided with a plurality of outlet section inner pipe mesh holes, there are two outlet section end rings, the two outlet section end rings are correspondingly sealed at both ends of the outlet section filling channel, the outlet section inner pipe is provided with an inlet hole in the middle, and the inlet section passes through the outlet section inner pipe outer pipe and is connected to the inlet hole. It can reduce the noise generated during vacuuming and exhausting, and can connect the exhaust pipe to one end of the air outlet section and close the other end as needed, so that the cutting bed with this utility model can better adapt to the use of different spaces and the exhaust pipe does not interfere with the installation.
[0005] Preferably, the inner diameter of the outlet section's inner tube is smaller than the inner diameter of the inlet section. This improves the effectiveness of sound entering the outlet section's filling channel, resulting in better noise reduction.
[0006] Preferably, the outer circumferential surface of the inner pipe of the air outlet section is provided with a plurality of air outlet section inner pipe reflective rings distributed along the extension direction of the inner pipe of the air outlet section. The air outlet section inner pipe reflective rings extend circumferentially along the inner pipe of the air outlet section, and the air outlet section inner pipe reflective rings are provided with a plurality of air outlet section inner pipe sound transmission holes, which penetrate the air outlet section inner pipe reflective rings. This can increase the noise rebound area and improve the noise reduction effect.
[0007] Preferably, both end faces of the reflector ring in the inner tube of the air outlet section are conical surfaces, with one end larger than the other facing the air inlet. This results in better noise reduction.
[0008] Preferably, the reflective ring of the inner pipe of the air outlet section is sealed and abutted against the inner surface of the outer pipe of the air outlet section. This can improve the noise reduction effect.
[0009] Preferably, both the inner and outer pipes of the air outlet section are circular pipes, and the sound transmission holes on the reflective rings of adjacent inner pipes are staggered radially. When the peaks and troughs of the sound wave are circumferentially oriented towards the inner pipe, they can be disrupted by the pipe wall; when the peaks and troughs are radially oriented towards the inner pipe, they are disrupted by the sound transmission holes, thereby improving the noise reduction effect.
