[0041] Working principle: When in use, the staff can place the cloth to be processed on the operating table 1, and it is located below the sewing machine body 3. The cloth can be processed and sewn by the operation of the sewing machine body 3. At this time, the staff can push the cloth forward to pass through the bottom of the conveying roller 43, and then the servo motor 576 and the dust suction pump 52 can be operated. When the servo motor 576 is in operation, it will drive the rotating rod 42 to rotate through the belt 421. When the rotating rod 42 rotates, it will drive the conveying roller 43 to rotate. When the conveying roller 43 rotates, the cloth can be transported forward, and before transportation, the knobs 484 on both sides can be rotated to drive the adjacent threaded sleeves 482 to rotate. When the threaded sleeves 482 rotate, the adjacent threaded rods 481 will move downward, and when the threaded rods 481 move downward, they will jointly drive the pressing plate 48 to move downward and contact the cloth, so as to prevent wrinkles during mobile transportation, and when the rotating rod 42 rotates, it can also drive the movable gear 44 to rotate. When the movable gear 44 rotates, The rack plate 45 meshing therewith is driven to rotate. When the rack plate 45 rotates, the adjusting seats 47 on both sides are driven to move backward synchronously through the fixed plate 46, the first connecting rod and the second connecting rod. At this time, the pressing plate 48 will also drive the cloth to move synchronously with the conveying roller 43, thereby improving the conveying effect, and there is no need for manual pushing by the staff. When the dust suction pump 52 is running, the dust suction hood 51 will generate suction, thereby absorbing the residual thread ends on the operating table 1, causing them to fall into the collecting tank 12 for collection, and the thread ends adsorbed on the filter screen 53 will fall under the action of the scraper 54 moving back and forth. When the servo motor 576 rotates, it will drive the worm 574 to rotate. When the worm 574 rotates, it will drive the transmission rod 572 to rotate through the worm gear 573. When the transmission rod 572 rotates, it will drive the movable rod 57 to rotate through the transmission belt 571. When the movable rod 57 rotates, it will drive the reciprocating screw 56 to rotate. When the reciprocating screw 56 rotates, it will drive the scraper 54 to move back and forth on the filter screen 53 through the screw nut 55, thereby playing a cleaning role.
