[0037] Furthermore, the lifting assembly three 37 includes a pair of support plates 371 vertically fixed on the top of the rectangular frame one 33, a pair of rotating shafts 372 horizontally located on both sides of the support plates 371 and rotating on the transfer frame 32, two pairs of gears 373 respectively fixedly installed on the rotating shafts 372 and symmetrically located on both sides of the support plates 371, two pairs of racks 374 respectively fixed on both sides of the support plates 371 and respectively meshing with the two pairs of gears 373, two pairs of connecting rods 375 respectively fixedly hinged on the two rotating shafts 372 at one end, two pairs of sliders 376 slidably arranged on the rectangular frame two 36 and respectively movably hinged to the other ends of the two pairs of connecting rods 375, and the two pairs of connecting rods 375 and the two pairs of sliders 376 are symmetrically located on both sides of the support plate 371.

[0038] By adopting the above technical solution, when the rectangular frame 1 33 rises or falls, the racks 374 on both sides of the support plate 371 will mesh with the gears 373 on the two rotating shafts 372, so that the rotating shafts 372 drive the two connecting rods 375 to flip in the closing or expanding direction, and then the two sliders 376 hinged to one end of the two connecting rods 375 will slide relatively close to or away from each other on the long square frame 2 under the flipping of the two connecting rods 375, and during the sliding process, drive the rectangular frame 2 36 to fall or rise, thereby realizing the alternating lifting and lowering of the rectangular frame 1 33 and the rectangular frame 2 36 in this way.

[0042] The working principle of this embodiment:

[0043] When it is necessary to cut and sew the plastic woven bag, firstly, the unwinding roller 13 with the rolled cloth roll is placed on two pairs of supporting rollers 12, and part of the woven cloth roll is manually pulled out to pass through the tensioning roller 14 at the upper end of each unwinding frame 11, the bottom of the pressing roller 22 on the cutting processing platform 21 and the middle of the gate-shaped bracket 24, and then the worm gear reduction motor 23 is started to drive the pressing roller 22 to rotate, so that the pressing roller 22 pulls the unwinding roller 13 to unwind the cloth roll through friction, until a certain length of the woven cloth roll passes through the cutting groove 27 under the gate-shaped bracket 24, the worm gear reduction motor 23 will stop driving the pressing roller 22, and the cylinder 26 will drive the cutter 25 to extend downward into the cutting groove 27, and then the long strip of woven cloth roll is automatically cut in this way;

[0044] At the same time, the lifting component 37 will lower the rectangular frame 2 36 before the above-mentioned woven tube cloth is cut, so that the lower surface of the belt 2 383 in the belt conveying component 2 38 is close to the surface of the cutting processing platform 21, and until one end of the belt 2 383 presses the woven tube cloth passing through the gate-shaped bracket 24, and then under the drive of the servo motor 2 384 of the belt conveying component 2 38, the pulley 2 382 will drive the belt 2 383 to press the woven tube cloth gradually away from the gate-shaped bracket 24, thereby keeping the surface of the woven tube cloth flat in this way;

[0045] Then, the woven tube cloth cut into small portions will continue to be conveyed a certain distance by the belt conveyor assembly 2 38, so that part of it moves to the bottom of the belt conveyor assembly 1 35, and then the cylinder 2 34 and the lifting assembly 3 37 will work simultaneously to make the rectangular frame 1 33 descend and the rectangular frame 2 36 rise. When the belt 2 383 in the belt conveyor assembly 2 38 is lifted away from the woven tube cloth and one end of the belt 1 353 in the belt conveyor assembly 1 35 presses the woven tube cloth, the servo motor 1 354 in the belt conveyor assembly 1 35 will immediately drive the pulley 1 352 to rotate, so that the belt 1 353 presses the woven tube cloth and conveys it in the direction away from the cutting processing platform 21.

[0046] Finally, when the woven tube cloth reaches the bottom of the feeding tray, the cylinder 2 34 and the lifting assembly 3 37 will work again, causing the rectangular frame 1 33 to rise and the rectangular frame 2 36 to fall. When the belt 1 353 in the belt conveying assembly 1 35 is lifted away from the woven tube cloth and the feeding tray on the rectangular frame 1 33 presses the woven tube cloth, the worm gear reduction motor 2 310 will immediately drive the rotating shaft 1 39 to rotate, causing the feeding tray to press the woven tube cloth to move to the belt 3 414 of the belt conveying assembly 3 41. At the top, since the upper surface of belt three 414 is flush with the surface of the conveying platform 31, and a plurality of pressing plates 322 are pressed on belt three 414, when the worm gear reduction motor three 415 drives pulley three 413 to rotate, belt three 414 and the pressing plates 322 thereon will convey the woven tube cloth away from the conveying platform 31, and during the conveying process, one end of the woven tube cloth will be automatically sewed and sealed by the automatic sewing machine 42, thereby realizing the continuous cutting and sewing processing of the plastic woven bag.

[0047] The above-mentioned fully automatic process of cutting and sewing plastic woven bags not only completely replaces manual labor and reduces the labor cost of plastic woven bags, but also a fast and automatic transfer mechanism 3 is provided between the cutting and sewing processes, thereby effectively shortening the production time of plastic woven bags and greatly improving the production efficiency of plastic woven bags.
