Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology, and in particular to a cutting bed exhaust pipe structure. Background Technology

[0002] In production and daily life, it is necessary to cut fluffy fabrics, which is done through a cutting table. In order to improve the cutting accuracy, a vacuum structure is set up to extract air from the fabric on the alignment conveyor belt, making the fabric more compact and improving the cutting accuracy. During vacuuming, the extracted air is discharged through an exhaust pipe. However, the exhaust pipe of the existing cutting table has the drawback of being noisy. Utility Model Content

[0003] This invention provides a cutting bed exhaust pipe structure with good noise reduction effect, which solves the problem of high noise during the exhaust of the cutting bed exhaust pipe.

[0004] The above technical problems are solved by the following technical solution: a cutting bed exhaust pipe structure, including an exhaust pipe head connected to the end of the exhaust main pipe, characterized in that it further includes a muffler pipe. Several positioning strips distributed circumferentially along the end face of the exhaust pipe head are connected to the end face of the exhaust pipe head. The positioning strips enclose the muffler pipe installation space, and limiting gaps are formed between adjacent positioning strips. Several limiting protrusions are provided on the outer circumferential surface of the muffler pipe. The muffler pipe is pluggably inserted into the muffler pipe installation space. The end face of the muffler pipe is supported on the end face of the exhaust pipe head with the positioning strips. The limiting protrusions are correspondingly inserted into the limiting gaps. In use, exhaust is discharged through the muffler pipe, thereby reducing noise. The muffler pipe is easy to install and remove; it can be pulled out by gripping the limiting protrusions. It is convenient to use and does not cause excessive rotation.

[0005] Preferably, the limiting protrusion is an elongated strip extending along the extension direction of the muffler tube. This increases the strength of the muffler tube.

[0006] Preferably, a lifting gap is provided between the limiting protrusion and the end face of the tube head with the positioning strip. This further facilitates the pulling out of the silencer tube.

[0007] Preferably, the muffler pipe includes a muffler end ring, a muffler outer tube, and a muffler inner tube passing through the muffler outer tube. A muffler filling channel is formed between the muffler outer tube and the muffler inner tube. The muffler filling channel is filled with muffler suction cotton. The muffler inner tube has several muffler mesh holes. There are two muffler end rings, which are correspondingly sealed at both ends of the muffler filling channel. This provides a specific structure for the muffler pipe.

[0008] Preferably, the inner diameter of the inner tube of the muffler section is smaller than the inner diameter of the end of the outlet pipe with the positioning strip. This improves the effect of sound entering the filling channel of the muffler section, resulting in better noise reduction.

[0009] Preferably, the outer circumferential surface of the inner tube of the muffler section is provided with a plurality of muffler section reflective rings distributed along the extending direction of the inner tube. The muffler section reflective rings extend circumferentially along the inner tube of the muffler section, and each reflective ring has a plurality of inner tube muffler section reflective ring sound transmission holes, which penetrate the reflective rings. This increases the noise rebound area and improves the noise reduction effect.

[0010] Preferably, both end faces of the muffler's reflector ring are conical surfaces, with one end larger than the other facing the inlet of the muffler's inner tube. This results in better noise reduction.

[0011] This invention has the following beneficial effects: it effectively eliminates noise during exhaust. Attached Figure Description
