[0020] 1. This utility model, by setting up a feeding mechanism, allows for continuous cutting by simply placing one end of the plastic woven bag under one of the feeding mechanisms. The second cylinder is activated to lower the feeding roller and press down on the plastic woven bag. Then, the first motor is activated to rotate the feeding roller, which feeds the plastic woven bag towards the cutting mechanism. After cutting, the second cylinder of the other feeding mechanism is activated to lower the feeding roller and press down on the plastic woven bag.

[0030] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] This utility model provides a technical solution:

[0032] Please see Figures 1-4 A device for cutting and pressing rough edges of plastic woven bags includes a cutting table 1, a cutting mechanism 2, and a feeding mechanism 3. The cutting mechanism 2 is located in the middle of the cutting table 1. The cutting mechanism 2 includes a cutting frame 21 fixedly installed on the cutting table 1. A first cylinder 22 is fixedly installed at the bottom of the cutting frame 21. A heating plate 23 is fixedly connected to the piston end of the first cylinder 22. A cutter 24 is fixedly connected to the bottom of the heating plate 23. By setting the cutting mechanism 2, when the plastic woven bag is sent to the bottom of the cutting frame 21, the first cylinder 22 can be activated to drive the cutter 24 to descend, so that the cutter 24 can cut the plastic woven bag without manual cutting.

[0033] Furthermore, the cutting table 1 has a blade groove 11 located directly below the cutter 24, and the heating plate 23 is equipped with a heating wire 27. By setting the heating plate 23 and the heating wire 27, the heating plate 23 is heated by the heating wire 27 during cutting. When the cutter 24 falls into the blade groove 11 to complete the cutting of the plastic woven bag, the heating plate 23 will press on the cut seam of the plastic woven bag to smooth the rough edges of the plastic woven bag and improve the flatness of the cut.

[0034] Furthermore, pressure plates 25 are provided on both sides of the cutter 24. A drive assembly 26 for driving the pressure plates 25 to rise and fall is provided inside the cutting frame 21. The drive assembly 26 includes a screw 261 rotatably installed inside the cutting frame 21 and a second motor 262 for driving the screw 261 to rotate. A movable plate 263 is threaded onto the screw 261. A connecting rod 264 is fixedly connected between the movable plate 263 and the pressure plate 25. A guide rod 265 is fixedly installed inside the cutting frame 21. The 63 is slidably connected to the guide rod 265. By setting the pressure plate 25 and the drive assembly 26, before starting the first cylinder 22 to control the cutter 24 to descend, the second motor 262 is started to drive the screw 261 to rotate. The screw 261 drives the movable plate 263 to slide vertically along the guide rod 265. The movable plate 263 drives the pressure plate 25 to descend through the connecting rod 264. The pressure plate 25 presses down on the plastic woven bags on both sides of the cutter 24, ensuring the stability of the plastic woven bags during cutting and improving the cutting quality.

[0035] Furthermore, a maintenance door 28 is hinged to one side of the cutting frame 21, which facilitates the maintenance of the interior of the cutting frame 21.

[0036] Reference Figure 1 and Figure 4 The feeding mechanism 3 is located on both sides of the cutting mechanism 2. The feeding mechanism 3 includes a feeding frame 31 fixedly installed on the cutting table 1. A second cylinder 32 is fixedly installed on the top of the feeding frame 31. A connecting frame 33 is fixedly connected to the piston end of the second cylinder 32. A feeding roller 34 is rotatably installed on the bottom of the connecting frame 33. A first motor 35 for driving the feeding roller 34 to rotate is fixedly installed on one end of the connecting frame 33. By setting the feeding mechanism 3, during continuous cutting, only one end of the plastic woven bag needs to be placed under one of the feeding mechanisms 3. The second cylinder 32 is activated to lower the feeding roller 34 and press down on the plastic woven bag. Then, the first motor 35 is activated to rotate the feeding roller 34, causing the feeding roller 34 to feed the plastic woven bag toward the cutting mechanism 2. After cutting, the second cylinder 32 of another feeding mechanism 3 is activated to lower the feeding roller 34 and press down on the plastic woven bag. Then, the first motor 35 is activated to rotate the feeding roller 34, causing the feeding roller 34 to deliver the cut plastic woven bag. This achieves automatic loading and unloading, reduces manual operation, and improves work efficiency.

[0037] Furthermore, limit rods 36 are fixedly connected to the top of both ends of the connecting frame 33. The limit rods 36 slide through to the top of the feeding frame 31. By setting the limit rods 36, the connecting frame 33 can be limited.

[0038] Furthermore, a rubber sleeve 37 is fixedly fitted onto the surface of the feeding roller 34. By setting the rubber sleeve 37, the friction of the surface of the feeding roller 34 can be increased, making the feeding roller 34 convey plastic woven bags more stably.

[0039] In practical use, the working principle of this utility model is as follows:

[0040] First, during continuous cutting, simply place one end of the plastic woven bag under one of the feeding mechanisms 3, start the second cylinder 32 to drive the feeding roller 34 to descend and press down the plastic woven bag, and then start the first motor 35 to drive the feeding roller 34 to rotate, so that the feeding roller 34 feeds the plastic woven bag toward the cutting mechanism 2.

[0041] Next, when the plastic woven bag is delivered to the bottom of the cutting frame 21, the second motor 262 is started to drive the screw 261 to rotate, so that the screw 261 drives the movable plate 263 to slide vertically along the guide rod 265, so that the movable plate 263 drives the pressure plate 25 to descend through the connecting rod 264, so that the pressure plate 25 presses down on the plastic woven bags on both sides of the cutter 24 to ensure the stability of the plastic woven bag during cutting.

[0042] Next, the first cylinder 22 can be activated to drive the cutter 24 to descend, so that the cutter 24 cuts the plastic woven bag. During the cutting, the heating plate 23 is heated by the heating wire 27. When the cutter 24 falls into the cutting groove 11 and completes the cutting of the plastic woven bag, the heating plate 23 will press on the cut of the plastic woven bag to smooth the rough edges of the plastic woven bag and improve the flatness of the cut.

[0043] After cutting, the second cylinder 32 of another feeding mechanism 3 is activated to drive the feeding roller 34 to descend and press down the plastic woven bag. Then, the first motor 35 is activated to drive the feeding roller 34 to rotate, so that the feeding roller 34 sends out the cut plastic woven bag, realizing automatic loading and unloading.

[0044] In summary, this plastic woven bag cutting and hot-edge pressing device, by setting up a cutting mechanism 2 and a feeding mechanism 3, can automatically load and unload plastic woven bags and perform cutting operations, reducing manual operation and improving work efficiency.

[0045] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
