A pair of pulleys 56 are fixedly mounted on the drive end of the third motor 54 and the axle of the third gear 55, respectively, and can drive the third gear 55 to rotate. The transmission belt 57 is movably fitted between the pair of pulleys 56. One end of the stop bar 58 is movable. The telescopic opening of the telescopic frame 53 is through which teeth are provided in the middle of the lower wall of the stop bar 58, which meshes with the third gear 55; a pair of brackets 51 provide stable support for the fifth electric slide rail 52; the fifth electric slide rail 52 drives the telescopic frame 53 to move as a whole, realizing the lateral position adjustment of the stop bar 58 to adapt to the folding positioning requirements of materials of different widths; the third motor 54 starts, and drives the third gear 55 to rotate through the transmission cooperation of a pair of pulleys 56 and a transmission belt 57; the third gear 55 meshes with the stop bar The teeth on the lower wall of 58 mesh with each other, converting the rotational motion into linear motion, which drives the stop rod 58 to extend or retract along the telescopic opening of the telescopic frame 53. After the stop rod 58 extends, it forms a reliable blocking limit at the folding part of the material, and cooperates with the folding structure 4 to complete the precise centering folding of the material. After folding, it cooperates with the material to move and ensure that the folded edge is neat and without misalignment. The stop rod 58 is used to block the folding part of the material, and the stop rod 58 is located between the second pressure frame 155 and the first pressure frame 153.

[0036] Through the transmission of the third motor 54 and the third gear 55, the stop bar 58 is engaged with the stop bar 58 to achieve extension and retraction, and the fifth electric slide rail 52 is adjusted laterally. It can flexibly adapt to the folding positioning requirements of materials of different sizes. Together with the folding structure 4, it can achieve precise alignment, centering limit, and stable guidance, effectively avoiding material folding deviation, wrinkles, and springback, significantly improving the folding forming quality and bag symmetry, and providing a reliable guarantee for subsequent sewing and sealing.

[0037] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0038] After the equipment is started, the woven bag substrate is guided into the feeding table 21 by the guide roller 22 of the feeding structure 2. Driven by the main body 23 of the second hydraulic cylinder, the crossbeam 24 drives the cutter 25 to press down and complete the fixed-length cutting of the substrate. After the cutting is completed, the third electric slide rail 26 drives the conveyor belt assembly 27 to descend and press the material, and transport the material to the turntable 20 in the reversing groove. The first motor 29 on the frame 28 drives the turntable 20 to rotate, realizing the orientation change of the material in the length and width directions. After the orientation change, the conveyor belt assembly 27 continues to transport the material to the unloading table 11 of the unloading structure 1. After the material reaches the designated position, the folding structure 4 is activated. The air pump body 491 provides negative pressure to generate suction force in the suction cup 49. The second electric push rod 48 pushes the suction cup 49 to adsorb the end of the material. The third hydraulic cylinder body 43 drives the second gear frame 44 to move linearly, meshing with the second gear 42 to drive the rotating shaft 40 to rotate, causing the fourth electric slide rail 41 to rotate the adsorption component. This, together with the adjustment plate 46, the adjustment seat 47, and the second motor 45, achieves material adsorption and traction. At the same time, the material blocking structure 5 is activated. The fifth electric slide rail 52 supported by the bracket 51 adjusts the lateral position of the telescopic frame 53. The third motor 54 drives the third gear 55 to rotate through the pulley 56 and the transmission belt 57, causing the stop rod 58 to extend and form a limit at the folding point of the material. This, together with the folding structure 4, completes the precise folding of the material. The material is then moved to the middle limit by the stop rod 58, allowing one end of the material to be folded in the center by the traction of the suction cup 49. After folding, the stop bar 58 and suction cup 49 can be moved to the left in sync, so that the folded edge is located at the weaving groove; at the same time, the pressing component 15 is activated, the first hydraulic cylinder body 152 on the first mounting bracket 151 drives the first pressing frame 153 to press down, and the second electric slide rail 154 drives the second pressing frame 155 to adjust the clamping position, firmly pressing the material at the L-shaped weaving groove 8 to prevent it from shifting during sewing, and the distance between the second pressing frame 155 and the first pressing frame 153 corresponds to the stop bar 58; Subsequently, the weaving unit 3 works, and the Y-axis electric slide rail 31, X-axis electric slide rail 32 and Z-axis electric slide rail 33 work together to drive the sewing machine body 34 to move along the weaving groove 8 track, complete the L-shaped sealing sewing of the bag edge, and thus add the edge of the fold to form a bag with an opening on one side. After sewing is completed, the bag can be detached via the stop bar 58 and pulled to the unloading plate 142 by the suction cup 49. The unloading group 14 is activated, and the first tooth frame 144 is driven by the first electric push 145 to move along the sliding groove 9 and mesh with the first gear 143 to drive the unloading plate 142 to rotate around the flipping seat 141. The finished bag body is flipped and falls onto the stacking platform 13 through the flipping opening 6. The first electric slide rail 12 drives the stacking platform 13 to decrease as the number of stacks decreases, so as to realize the continuous and orderly stacking of finished products and complete a complete process of woven bag cutting, reversing, folding, sewing and unloading.

[0039] In summary, the woven bag substrate is conveyed and cut to a fixed length by the feeding structure 2, and the length and width orientation of the material is adjusted by the turntable 20. Then it is sent to the unloading table 11, where the folding structure 4 and the blocking structure 5 work together to fold the material in the center. The pressing component 15 presses the folded material tightly at the weaving groove 8, and the weaving unit 3 drives the sewing machine body 34 to complete the sealing sewing along the L-shaped trajectory through the linkage of the three-axis slide rail. Finally, the unloading component 14 flips and unloads the material, and the finished product falls onto the stacking table 13 controlled by the electric slide rail and is stacked in an orderly manner, realizing the integrated automatic processing of cutting, reversing, folding, sewing and unloading.
