[0002] In the processing fields of flexible materials such as garments and luggage, the cutting of the bag mouth is a key process affecting the structural accuracy and aesthetics of the finished product. Traditional bag mouth cutting equipment generally adopts a fixed bottom plate mechanism, and the adjustment of the bag mouth size and shape depends on manually replacing templates or mechanical positioning adjustments, resulting in low adjustment efficiency of the bottom plate bag mouth. The existing mechanical adjustment mechanism manually adjusts the position of the baffle through a screw or a slide rail, and needs to be repeatedly measured and calibrated, which cannot meet the requirement of quickly switching multiple specifications of bag mouths. Especially in small-batch customized production, it takes a long time. At the same time, in order to adapt to this adjustment, the overall structure of the existing mechanical adjustment mechanism is relatively complex and the volume of the device is large, and corresponding sensing components are designed for adjustment. For customized production, the actual cost of the equipment device is relatively high. Summary of the Invention

At this time, the sixth rack 631 and the seventh rack 632 respectively engage with the bottom small gear rings of two second gear sets 633, and the top large gears of the second gear sets 633 engage with the eighth rack 635, thereby causing the limiting members 636 on the eighth rack 635 to approach each other, thereby performing corresponding limiting on the length of the bag mouth to be cut, and reversely driving the second motor 61 according to the need for bag mouth sewing of the cut fabric to realize the mutual separation of the material pulling members 616 and perform the tensioning work on the cutting side end of the fabric bag mouth.

[0027] Specific implementation process: The technical solution of this application is mainly used in the process of opening, cutting, and sewing bags for fabrics. First, drive the first motor 51 to drive the screw rod on the output shaft to rotate. The screw rod engages with the first screw sleeve seat 52, and enables the Z-shaped folding plate 53 to displace directionally in the front slot of the rear vertical plate 12, thereby driving the L-shaped rack 55 to slide horizontally. The L-shaped rack 55 engages with the lower part of the first thick gear 56, the upper part of the first thick gear 56 engages with the short rack 57, and drives the upper bottom plate 513 to reciprocate through the sliding setting of the slide rail 512 and the second sliding sleeve 514 by the T-shaped plate 59 fixed by the bolt at the upper end of the short rack 57. At the same time, drive the second limiting plate 517 connected to the third connecting plate 516 on the cylinder seat 515 by the third cylinder 511 to limit the fabric on the upper side of the fabric bag opening position to set the width of the bag mouth; Start the second motor 61. Utilize the engagement between the lead screw 62 and the second screw bushing 63. The second screw bushing 63 then drives two first racks 65 to engage with the upper half of the second thick gear 67 through the first connecting rod 64, and the lower half of the second thick gear 67 engages with the second rack 610, thereby driving the third rack 612 at the front ends of the two second racks 610 to slide longitudinally with the ninth rack. At this time, the third rack 612 and the ninth rack respectively engage with the bottom small gear rings of two first gear sets 613, and the top large gears of the first gear sets 613 engage with the tenth rack 615, so that the material pulling members 616 on the tenth rack 615 approach each other. At the same time, start the third motor 620. Utilize the engagement between the screw 621 and the third screw bushing 622. The third screw bushing 622 then drives two fourth racks 625 to engage with the upper half of the third thick gear 627 through the second connecting rod 623, and the lower half of the third thick gear 627 engages with the fifth rack 628, thereby driving the sixth rack 631 and the seventh rack 632 at the front ends of the two fifth racks 628 to slide longitudinally. At this time, the sixth rack 631 and the seventh rack 632 respectively engage with the bottom small gear rings of two second gear sets 633, and the top large gears of the second gear sets 633 engage with the eighth rack 635, so that the limiting members 636 on the eighth rack 635 approach each other, thereby performing corresponding limiting settings on the length of the bag mouth to be cut. Lay the fabric flat on the working plane of the extension plate 2, and send the fabric under the laser cutting device for bag mouth cutting with preset parameters. Secondly, an external servo drive device drives the lead screw to rotate, and cooperates with the slide bar to axially position and adjust the sliding bushing 42. Subsequently, start the second cylinder 46, and the limiting plate 48 connected to the output shaft connecting plate 47 of the second cylinder 46 slides, and the fabric is limited and hemmed on the lower side of the bag opening position of the fabric. According to the required sewing size of the bag mouth of the cut fabric, drive the first cylinder 43. The material pulling plate 45 connected to the front end connecting plate 44 of the output shaft of the first cylinder 43 will limit the lower side of the bag mouth dynamically after the fabric is opened. Then drive the fourth cylinder 519 to drive the material pulling plate 521 at the front end of the cylinder connecting plate 520 to complete the positioning of the upper sewing line position of the bag mouth, achieving corresponding tensioning, so as to ensure the accuracy of sewing during the subsequent placement and sewing of the bag mouth strips, and ensure the flatness of the stitch in the subsequent automatic sewing process. Finally, drive the second motor 61 in reverse to realize the mutual separation of the material pulling members 616, perform tensioning work on the cut side end of the fabric bag mouth, and then fold the fabric bag mouth through an external hemming mechanism, thereby completing the subsequent sewing work.
