When the top rod 14 moves downward, it drives the tensioning roller 15 to move downward to tighten the fabric 9. At this time, the wrinkles on the surface of the fabric 9 are opened. At the same time, when the top rod 14 moves downward, it drives the cross bar 11 to move downward, so that the telescopic rod 16 connected to the other end of the cross bar 11 is shortened, driving the cleaning roller 21 to move downward and fit closely with the fabric 9, so that the dust and debris in the wrinkles can be fully cleaned, thereby improving the cleaning effect.

When the cutting length needs to be adjusted, the adjusting motor 49 is started to make the bidirectional threaded rod 45 start to rotate. When the bidirectional threaded rod 45 rotates, it drives the sliders 43 threadedly connected thereto to start synchronously moving toward each other on both sides of the bidirectional threaded rod 45, driving the spacing between the cutting knives 44 to increase or decrease, thereby adjusting the cutting distance of the fabric 9; when the slider 43 moves, it drives the connecting frame to move accordingly, so that the baffle 50 at the other end of the connecting frame moves accordingly when the cutting knife 44 moves, thereby ensuring that the position of the fabric 9 when passing through the right reversing roller 41 is directly below the right reversing roller 41, thereby avoiding the fabric 9 from being skewed during movement.

[0032] When the fabric 9 moves, it passes under the nozzle 31 at the bottom of the ironing device 28. At this time, the steam generator 25 is started, so that the high-temperature steam flows into the ironing device 28 along the air inlet pipe 27, and then is sprayed out through the nozzle 31 to iron the fabric 9, remove the wrinkles on the surface of the fabric 9, and ensure the flatness of the fabric 9 during cutting. After ironing, the fabric 9 flows out along the discharge port 26. The high-temperature steam sprayed out by the nozzle 31 condenses into liquid after cooling and passes through the filter plate 33 to flow into the interior of the liquid collecting tank 32, so as to facilitate its recycling. When the fabric 9 enters the feed port 24, it contacts the friction block 36. The friction block 36 moves to the right under the action of the friction force, so that the piston rod 37 moves to the right. When the piston rod 37 moves, it drives the first piston 38 to move toward the right end of the piston cylinder. When the wrinkles on the surface of the fabric 9 are deeper, the friction force on the friction block 36 is greater, and the amplitude of the rightward movement is greater, so that the wrinkle degree of the fabric 9 can be determined while ironing.

[0033] When the first piston 38 moves to the right, it pushes the hydraulic oil inside the first piston cylinder 34 to flow along the pipeline into the top of the second piston cylinder 10, so that the second piston 12 moves to the bottom of the second piston cylinder 10, and the spring 13 is compressed to generate elastic force in the opposite direction. The downward movement of the second piston 12 drives the push rod 14 to move downward, so that the tensioning roller 15 moves downward synchronously, so that the fabric 9 at the bottom of the tensioning roller 15 is tightened, reducing the depth of the wrinkles of the fabric 9 during ironing and improving the ironing effect; when the fabric 9 passes through the bottom of the tensioning roller 15, friction is generated, so that the tensioning roller 15 rotates counterclockwise. When the tensioning roller 15 rotates, it drives the driving wheel 18 to start rotating through the connecting shaft. When the driving wheel 18 rotates The driven wheel 19 is driven by the cross transmission belt 20 meshing therewith to start rotating in the opposite direction. When the driven wheel 19 rotates, the cleaning roller 21 is driven by the cleaning shaft to rotate in the opposite direction of the tensioning roller 15, so that the cleaning brush 22 on the surface of the cleaning roller 21 rotates synchronously to clean the dust and debris on the surface of the fabric 9. When the top rod 14 moves downward, it drives the tensioning roller 15 to move downward to tighten the fabric 9. At this time, the wrinkles on the surface of the fabric 9 are opened. At the same time, when the top rod 14 moves downward, it drives the cross bar 11 to move downward, so that the telescopic rod 16 connected to the other end of the cross bar 11 is shortened, driving the cleaning roller 21 to move downward and fit closely with the fabric 9, so that the dust and debris in the wrinkles can be fully cleaned, thereby improving the cleaning effect.

[0034] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
