A plurality of cutting grooves 14 are provided on the top of the base plate 1. By providing the cutting grooves 14, it is possible to prevent the cutter 95 from directly cutting on the base plate 1, thereby damaging the base plate 1 or failing to cut the plastic woven bag located at the bottom. By providing a plurality of cutting grooves 14 at the same time, the scope of application is also wider. By providing an open groove 5 on the two top rods 4 and providing a movable rod 3 between the two open grooves 5, the rotating motor 8 and the electric telescopic rod 7 can make the plastic woven bag on the movable rod 3 fall on the top of the base plate 1 in a zigzag shape, and then the woven bag can be cut by the cutting assembly 9 to achieve one-time cutting of multiple woven bags. This structure can improve the cutting efficiency.

[0025] Please participate Figure 3As shown, a sliding groove 10 is provided on one side of the left push rod 4 and above and below the opening groove 5. A stud screw 11 is slidably connected to the inner surface of the sliding groove 10. The stud screw 11 serves to fix the mounting plate 15, and when the movable rod 3 moves on the inner surface of the opening groove 5, the stud screw 11 synchronously slides on the inner surface of the sliding groove 10. A mounting plate 15 is provided between the outer surfaces of the two stud screws 11. A rotating motor 8 is fixedly connected to one side of the mounting plate 15. The rotating motor 8 is electrically connected to an external power supply. The output end of the rotating motor 8 passes through the mounting plate 15 and extends to the outside of the mounting plate 15. The output end of the rotating motor 8 is fixedly connected to one end of the movable rod 3. The outer surfaces of both ends of the stud screw 11 are threadedly connected with connecting nuts 12. The cutting assembly 9 includes a slide plate 91 located on both sides of the top of the base plate 1, the inner surfaces of the two slide plates 91 are slidably connected with a sliding rod 92, a support plate 93 is fixedly connected between the tops of the two sliding rods 92, a cylinder 94 is fixedly connected to the top of the support plate 93, the cylinder 94 is electrically connected to an external power supply, the output end of the cylinder 94 passes through the support plate 93 and extends to the outside of the support plate 93, and the output end of the cylinder 94 is fixedly connected to a cutter 95.

[0026] Please participate Figure 4 As shown, both sides of the surface of the cutter 95 are fixedly connected with a wrapping sleeve 96, and the front and back sides of the wrapping sleeve 96 are fixedly connected with a mounting sleeve 97 through a positioning piece 98. The top of the inner cavity of the mounting sleeve 97 is fixedly connected with a spring 99, and the bottom end of the spring 99 is fixedly connected with a connecting rod 910. The bottom end of the connecting rod 910 penetrates the mounting sleeve 97 and extends to the outside of the mounting sleeve 97. The bottom end of the connecting rod 910 is fixedly connected with a pressing block 911, and the material of the pressing block 911 is rubber. By arranging the wrapping sleeve 96 on the surface of the cutter 95 and utilizing the limiting sleeve 13 included thereon, when the cutter 95 moves downward, the pressing block 911 can first contact with the plastic woven bag, thereby pressing the plastic woven bag tightly to prevent the plastic woven bag from being offset when the cutter 95 is cutting, resulting in different sizes of the cut plastic woven bag. This structure can improve its cutting accuracy and further improve its practicability.

[0027] In summary, by placing the woven bags in a zigzag shape on the bottom plate 1 and cutting the woven bags by the falling of the cutter 95, a plurality of woven bags can be cut out at one time, thereby improving the cutting efficiency.

[0028] The working principle of the present invention is as follows: first, by pulling the rotating motor 8, the movable rod 3 is pulled out from the connecting block 6 on one side, and then the hollow roller wrapped with the plastic woven bag is sleeved on the outer surface of the movable rod 3. At this time, the rotating motor 8 is pushed again, so that the movable rod 3 passes through the connecting block 6 and the opening groove 5 in sequence, and then the limiting sleeve 13 is screwed on one end of the movable rod 3. At this time, the stud screw 11 also passes through the inner surface of the sliding groove 10, and then the connecting nut 12 is screwed on the right end of the stud screw 11. At this time, the rotating motor 8 and the electric telescopic rod 7 are started at the same time. The rotating motor 8 drives the movable rod 3 to rotate, so that the plastic woven bag on the movable rod 3 is opened and laid flat above the bottom plate 1, and the electric telescopic rod 7 is extended and shortened, driving the movable rod through the connecting block 6 3 makes a reciprocating motion on the inner surface of the opening groove 5, so that the plastic woven bag on the movable rod 3 is laid flat on the top of the bottom plate 1 in a zigzag shape. When the movable rod 3 is laid flat, the sliding rod 92 slides on the inner surface of the slide groove plate 91 by pushing the support plate 93. When the support plate 93 slides to the top of the plastic woven bag, the cylinder 94 is started to extend, so that the cutter 95 moves downward. When the pressing block 911 contacts the plastic woven bag, the cutter 95 continues to move downward. At this time, the connecting rod 910 on the pressing block 911 slides upward on the inner surface of the mounting sleeve 97, so that the spring 99 is compressed, thereby pressing the plastic woven bag tightly until the cutter 95 falls on the inner surface of the cutting groove 14, thereby cutting a plurality of plastic woven bags at one time.
