[0030] Refer to Figures 1-6, an embodiment provided by the present utility model: a fabric cutting machine, including a frame 1, a conveying mechanism 2 is arranged at the top of the frame 1. The conveying mechanism 2 can facilitate the transmission work of the fabric, so as to facilitate the continuous automatic transmission and cutting work of the fabric. A fixed frame 3 is fixedly connected to the top of the frame 1, and an electric push rod 4 is fixedly installed on the fixed frame 3. The output end of the electric push rod 4 and at the inner top end of the fixed frame 3 is fixedly connected with a lifting frame 5. A moving frame 6 is arranged below the lifting frame 5, and an electric guide rail 7 is installed between the lifting frame 5 and the moving frame 6. A second motor 8 is arranged in the moving frame 6, and a cutting wheel 9 is fixedly installed at the output end of the second motor 8. The electric push rod 4 drives the lifting frame 5 to descend. The lifting frame 5 can drive the moving frame 6 to descend, and the moving frame 6 drives the cutting wheel 9 to descend close to the fabric to be cut. A fixed block 10 is fixedly connected to the bottom of the lifting frame 5, and a pressing frame 11 is arranged at the bottom of the fixed block 10. A pressing mechanism is arranged between the fixed block 10 and the pressing frame 11. The pressing mechanism cooperates with the pressing frame 11 to press the fabric to be cut, so as to ensure the stability of the fabric positioning during cutting, and it is not easy to slide or shift, so as to ensure the flatness and stability of the cut of the fabric during cutting. A centralized groove 16 is arranged in the pressing frame 11, and an extraction hole 17 communicated with the centralized groove 16 is arranged on one side of the outer surface of the pressing frame 11. A plurality of extraction holes 17 are arranged and evenly distributed on the pressing frame 11. An extraction pipe 18 with the bottom end communicated with the centralized groove 16 is arranged outside the fixed frame 3. A suction fan 19 and a treatment box 20 are respectively arranged at the top of the fixed frame 3. The top end of the extraction pipe 18 is communicated with the air inlet end of the suction fan 19, and the air outlet end of the suction fan 19 is communicated into the treatment box 20. A filter screen structure is arranged in the treatment box 20, and an air outlet 23 is arranged on the treatment box 20. When the pressing frame 11 presses the fabric, after cutting is completed, when the suction fan 19 works, the fabric debris and dust generated during cutting are sucked into the centralized groove 16 from the extraction holes 17, then into the extraction pipe 18, and finally sent into the treatment box 20. After being filtered by the filter screen structure, the fabric debris and dust can be filtered out.

[0031] The conveying mechanism 2 includes a plurality of conveying rollers 201 arranged on the frame 1. A conveying belt 202 is drivingly connected to the plurality of conveying rollers 201. A first motor 205 with an output end fixedly connected to the central axis of one of the conveying rollers 201 is arranged on the frame 1. There are two conveying mechanisms 2 in total and they are located on both sides of the fixing frame 3. Synchronous sprockets 203 are nested and fixedly connected to the central axes of two adjacent conveying rollers 201 on the two adjacent conveying mechanisms 2 that are close to each other in position. The two synchronous sprockets 203 are drivingly connected by a synchronous chain 204. The two groups of conveying mechanisms 2 can perform stable conveying work on the fabric. When the first motor 205 drives one of the conveying rollers 201 to rotate, it can drive the conveying belt 202 to move, so that the conveying work of the fabric can be carried out. The cooperation setting of the synchronous sprockets 203 and the synchronous chain 204 can make the two conveying belts 202 run synchronously, so that the two parts of the fabric after cutting can be conveyed and moved.

[0032] The pressing mechanism includes an inner groove 12 arranged in the fixing block 10. A movable block 13 is slidably connected in the inner groove 12, and a buffer spring 14 is connected between the top of the inner wall of the inner groove 12 and the top of the movable block 13. A connecting block 15 penetrating through the bottom wall of the inner wall of the inner groove 12 is fixedly connected to the bottom of the movable block 13. The connecting block 15 is fixedly connected to the pressing frame 11. When the lifting frame 5 drives the fixing block 10 to descend, when the fixing block 10 drives the pressing frame 11 to descend and fit onto the surface of the fabric and press it, at this time the pressing frame 11 pushes the movable block 13 to rise through the connecting block 15, and the movable block 13 compresses the buffer spring 14. After the buffer spring 14 is compressed, its elastic effect can make the pressing frame 11 firmly and stably press on the fabric, ensuring the stability of its pressing, so as to ensure that when the fabric is cut, it is not easy to deviate or skew.
