The output end of the cylinder 5 is fixedly connected to the top of the cutting knife 6. A feeding assembly 7 is installed on the operating table 1, and limiting assemblies 8 are slidably installed on both sides of the operating table 1. First, manually pass one end of the plastic woven bag on the unwinding roller 3 through the feeding assembly 7 and pull it to the other end of the operating table 1. Then, slide and adjust the position of the limiting assembly 8 according to the length of a single plastic woven bag to limit the moving stroke of the feeding assembly 7. Next, use the feeding assembly 7 to convey the plastic woven bag, thus achieving the purpose of using the feeding assembly 7 to replace the traditional conveyor belt or rotating roller to convey the plastic woven bag, avoiding the situation of slipping when the conveyor belt or rotating roller conveys the plastic woven bag, which affects the cutting accuracy of the plastic woven bag. Finally, start the cylinder 5 to drive the cutting knife 6 to descend in the fixed frame 4 to cut and trim the plastic woven bag.
[0019] The feeding assembly 7 includes a sliding plate 74, and the sliding plate 74 is slidably clamped on the operating table 1. A lead screw 72 is rotatably installed in the operating table 1, and the lead screw 72 is threadedly inserted into the sliding plate 74.
[0020] By adopting the above technical solution, the lead screw 72 drives the sliding plate 74 to reciprocate on the operating table 1.
[0021] A positive and negative motor 71 is fixedly installed at one end of the operating table 1, and the output end of the positive and negative motor 71 is fixedly connected to one end of the lead screw 72.
[0022] By adopting the above technical solution, start the positive and negative motor 71 to drive the lead screw 72 to rotate forward and backward.
[0023] Driving gears 76 are rotatably installed at both ends of the sliding plate 74, and threaded rods 77 are fixedly installed on both driving gears 76. Clamping plates 75 are threadedly sleeved on the two threaded rods 77.
[0024] By adopting the above technical solution, the driving gear 76 drives the threaded rod 77 to rotate, and the threaded rod 77 drives the clamping plate 75 to move up and down to clamp and loosen the plastic woven bag.
[0025] Both sides of the operating table 1 are provided with sliding grooves 11. Tooth plates 73 are slidably clamped in the two sliding grooves 11, and the tooth plates 73 are meshed with corresponding driving gears 76.
[0026] By adopting the above technical solution, the tooth plate 73 slides in the sliding groove 11, and the driving gear 76 meshes with the tooth plate 73 to drive the driving gear 76 to rotate.
[0027] Both of the two limiting components 8 include limiting blocks 81, and the limiting blocks 81 are slidably clamped in the corresponding sliding grooves 11.
[0028] By adopting the above technical solution, the position of the limiting block 81 is slidably adjusted according to the length of a single plastic woven bag to limit the tooth plate 73.
[0029] Bolts 82 are fixedly installed on both of the two limiting blocks 81, and locking nuts 83 are threadedly sleeved on the two bolts 82.
[0030] By adopting the above technical solution, the position of the limiting block 81 is slidably adjusted according to the length of a single plastic woven bag, and the locking nut 83 is rotated to fix the limiting block 81 to limit the tooth plate 73.
[0031] One end of the operating table 1 close to the fixing frame 4 is fixedly installed with a sliding plate 12, and a collection box 2 is placed directly below the sliding plate 12.
[0032] By adopting the above technical solution, the cut and trimmed plastic woven bags slide into the collection box 2 through the sliding plate 12.
[0033] Working principle: First, manually pass one end of the plastic woven bag on the unwinding roller 3 through the feeding assembly 7 and pull it to the other end of the operating table 1. Then, slide and adjust the position of the limit block 81 according to the length of a single plastic woven bag, and rotate the locking nut 83 to fix the limit block 81 to limit the toothed plate 73, thereby limiting the moving stroke of the feeding assembly 7. Next, start the forward and reverse motor 71 to drive the lead screw 72 to rotate. The lead screw 72 drives the sliding plate 74 to slide on the operating table 1 towards the unwinding roller 3. While the sliding plate 74 slides, it pushes the toothed plate 73 to slide in the chute 11 through the driving gear 76. When the toothed plate 73 slides to one end of the chute 11, the driving gear 76 meshes with the toothed plate 73 and drives the driving gear 76 to rotate. The driving gear 76 drives the threaded rod 77 to rotate, and the threaded rod 77 drives the clamping plate 75 to descend to clamp the plastic woven bag. Then, reverse the forward and reverse motor 71 to drive the lead screw 72 to rotate in the reverse direction. The lead screw 72 drives the sliding plate 74 to slide on the operating table 1 towards the fixed frame 4 to convey the plastic woven bag. While the sliding plate 74 slides, it pushes the toothed plate 73 to slide in the chute 11 through the driving gear 76. When the toothed plate 73 slides to contact the limit block 81, the driving gear 76 meshes with the toothed plate 73 and drives the driving gear 76 to rotate in the reverse direction. The driving gear 76 drives the threaded rod 77 to rotate, and the threaded rod 77 drives the clamping plate 75 to rise to release the clamping of the plastic woven bag. Finally, start the cylinder 5 to drive the cutting knife 6 to descend in the fixed frame 4 to cut and trim the plastic woven bag. The cut and trimmed plastic woven bag slides into the collection box 2 through the slide plate 12.
