Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology, and in particular to a cutting bed with an adsorption system that allows for interchangeable air outlet directions. 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. In existing cutting tables, the exhaust pipe is fixed on one side of the cutting table. When the cutting table is installed in different parts of the workshop, interference will occur. Utility Model Content

[0003] This invention provides a cutting bed with an adsorption system that allows the exhaust pipe to be installed on either side of the cutting bed, thus solving the problem of interference caused by the exhaust pipe of the cutting bed being installed on only one side.

[0004] The above technical problems are solved by the following technical solution: a cutting bed with an adsorption system having a changeable exhaust direction, comprising a frame, characterized in that the frame is provided with a feeding conveyor belt, a discharging conveyor belt connected to the discharging end of the feeding conveyor belt, a cutting blade for cutting the material covered with a film on the feeding conveyor belt, and an adsorption system for vacuuming the material located on the feeding conveyor belt, the adsorption system comprising an exhaust fan, an air intake structure connected to the inlet end of the exhaust fan, and an exhaust manifold connected to the outlet end of the exhaust fan, the air intake structure comprising an air intake chamber closed at the upper end by the feeding conveyor belt and an air intake pipe connecting the air intake chamber and the inlet end of the exhaust fan, the exhaust manifold comprising an air intake section and an air outlet section, the air outlet section extending from one end of the frame in the width direction to the other end, the air intake section being connected to the middle of the air outlet section, both ends of the air outlet section being detachably connected to an air outlet pipe cover or an exhaust pipe, the air outlet pipe cover and the exhaust pipe being each connected to one end of the air outlet section. It can vacuum-absorb and flatten materials, resulting in clean cuts. The exhaust pipe can be connected to either side of the frame, depending on the installation location, avoiding interference.

[0005] Preferably, the air outlet section includes an air outlet section end ring, an outer air outlet section tube, and an inner air outlet section tube passing through the outer air outlet section tube. An air outlet section filling channel is formed between the outer and inner air outlet section tubes. The air outlet section filling channel is filled with air outlet section suction cotton. The inner air outlet section tube has several mesh holes. There are two air outlet section end rings, each correspondingly sealing one end of the air outlet section filling channel. An air inlet hole is provided in the middle of the inner air outlet section tube. The air inlet section passes through the outer air outlet section tube and connects to the air inlet hole. This design reduces noise generated during vacuum exhaust and allows the exhaust pipe to be connected to one end of the air outlet section while the other end is closed, enabling the cutting bed with this invention to better adapt to different spaces without the exhaust pipe interfering with installation.

[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, 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.

[0009] Preferably, the main air intake chamber is equipped with an isolation plate, which isolates an air intake cavity within the main air intake chamber. The isolation plate has filter holes in its isolation plate portion. The inlet end of the air intake pipe is located within the air intake cavity. A filter cover connected to the inlet end of the air intake pipe is installed within the air intake cavity. The filter cover has filter holes in its filter cover portion, the diameter of which is smaller than the diameter of the filter holes in the isolation plate portion. The filter cover has a tubular structure, with an end cap at one end and the other end connected to the inlet end of the air intake pipe. In use, the material conveyed at the feeding end is compressed by vacuuming. The vacuumed airflow flows sequentially through the main air intake chamber, the air intake cavity, and the filter cover before reaching the air intake pipe. During vacuuming, the chips generated during cutting by the cutting bed are filtered and blocked sequentially by the filter holes in the isolation plate portion and the filter holes in the filter cover portion, thereby preventing them from entering the exhaust fan and damaging the equipment or polluting the air.

[0010] Preferably, the wall of the air inlet cavity is provided with a filter cover removal hole, and the end cap is detachably connected to the filter cover removal hole to close it. When the filter cover needs cleaning, the end cap is detached from the filter cover removal hole, and then the filter cover is removed. This facilitates filter cover maintenance.

[0011] Preferably, the air inlet cavity is provided with a tubular section, one end of which forms the filter cover disassembly hole, and the filter cover is inserted inside the tubular section. This allows airflow to converge and enter the air inlet duct.

[0012] Preferably, the exhaust fan is located below the frame.

[0013] The present invention has the following advantages: the exhaust pipe can be installed on either the left or right side of the cutting bed. Attached Figure Description
