[0026] Working principle: Woven bags are woven from materials such as plastic, paper and grass, and are usually used to store or carry items. They are light, strong and environmentally friendly, and are widely used in supermarket shopping bags and handicraft packaging bags. In order to facilitate use, woven bags need to be divided into suitable sizes during production. When the existing cutting machine is used, if the woven bag is folded or wrinkled during transportation, the cutting device cannot smooth it out, resulting in an uneven cutting position of the woven bag, making it impossible to use it normally. In order to solve this problem, a cutting mechanism and a feeding mechanism are set to insert the woven bag into the bottom side of the driving roller 19 and the driven roller 22, and the servo motor 20 is controlled to drive the output end driving roller 19 to rotate, and at the same time drive the driving wheel 23 to rotate. At this time, under the cooperation of the belt 25 and the driven wheel 24, the driven roller 22 is driven to rotate, and the driven roller 22 and the driving roller 19 have the same rotation direction and speed, thereby pushing the woven bag on the bottom side to move on the surface of the processing table 1, and at the same time, the woven bag will drive the feed roller 13 to rotate. The feed roller 13 drives the gear 14 to rotate, thereby bending the elastic block 15, and then under the action of elastic force, the elastic block 15 is buckled at the position of the next tooth on the gear 14, thereby preventing the feed roller 13 from rotating under the action of inertia, so that the woven bag is in a taut and straight state, and in the conveying process, when the woven bag passes through the fixed platform 16, the scraper 17 flattens the wrinkles on the surface of the woven bag, and the woven bag cutting position is conveyed to the top side of the cutting groove 11, and the cylinder 9 is controlled to push the cutting blade 3 down through the piston rod 10. At this time, the flat plate 6 contacts the woven bag, and the cutting blade 3 continues to descend, thereby pushing the connecting rod 5 to rotate around the shaft rod 4. At this time, the flat plates 6 on both sides will stretch the woven bag to both sides, thereby smoothing and straightening its folds or wrinkles. At this time, the cutting blade 3 cuts the woven bag with the cooperation of the cutting groove 11, and then the cylinder 9 is controlled to drive the cutting blade 3 to rise, and the spring 8 pulls the connecting rod 5 to retract the flat plate 6 to complete the cutting process, thereby solving the problem that the existing cutting device cannot smooth the folds or wrinkles of the woven bag, resulting in uneven incision of the woven bag.
