[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example: See Figure 1-6 This utility model discloses a folding device for producing plastic woven bags, comprising a support plate 1, which is U-shaped, with a guide plate 2 horizontally fixedly connected to the upper ends of the support plate 1. An inverted U-shaped support frame 3 is fixedly connected to the upper ends of the support plate 1 on both sides of the guide plate 2. A lifting mechanism is installed at the lower end of the inverted U-shaped support frame 3, and positioning mechanisms are installed on both sides of the lifting mechanism. A bending mechanism is installed on one side of the positioning mechanism, and a pressing mechanism is installed at the rear end of the bending mechanism. Through the U-shaped design of the support plate 1, in conjunction with the guide plate 2, the inverted U-shaped support frame 3, and the lifting, positioning, bending, and pressing mechanisms, the integrated operation of folding plastic woven bags is easily achieved. The lifting mechanism includes lifting grooves 4 vertically formed on both sides of the inverted U-shaped support frame 3. The vertical direction of the lifting grooves 4... A fixed plate 11 is slidably installed, and a lifting plate 7 is fixedly connected between the fixed plates 11. An electric telescopic rod 5 is installed on the inverted U-shaped support frame 3 at the upper middle part of the lifting plate 7. The telescopic end of the electric telescopic rod 5 passes through the inverted U-shaped support frame 3 and is fixedly connected to the middle of the upper part of the lifting plate 7. Through the sliding cooperation between the lifting groove 4 on the inverted U-shaped support frame 3 and the fixed plate 11, and the connection between the electric telescopic rod 5 and the lifting plate 7, the vertical lifting adjustment of the lifting plate 7 can be easily realized. The positioning mechanism includes a rotating rod that is rotatably installed between the lower ends of the fixed plates 11. A fixed roller 12 is sleeved in the middle of the rotating rod. Moving rings are slidably sleeved on both sides of the fixed roller 12. Through the rotating rod, the fixed roller 12 and the moving rings at the lower end of the fixed plate 11, the bending position of the plastic woven bag can be initially positioned and limited.

[0022] In this invention, a bidirectional screw 15 is rotatably mounted between the fixed plates 11, and a servo motor 6 is mounted on one side of the fixed plates 11. The output end of the servo motor 6 is snapped into one end of the bidirectional screw 15. The servo motor 6 on one side of the fixed plates 11 drives the bidirectional screw 15 to rotate, which facilitates the horizontal movement control of the moving ring and the sliding seat 13. The bending mechanism includes a sliding seat 13 that is movably sleeved on both ends of the bidirectional screw 15 by threaded connection. The lower end of the sliding seat 13 is rotatably snapped into one side of the moving ring, and a T-shaped moving groove 8 is opened on one side of the lifting plate 7 at the upper end of the sliding seat 13. A moving plate 9 is horizontally slidably mounted in the T-shaped moving groove 8, and the upper end of the moving plate 9 is fixed to the lifting plate 7 by fixing bolts. Furthermore, the lower end of the movable plate 9 is provided with an adjustment groove, in which a positioning plate 16 is fixedly installed by an adjustment bolt. A triangular folding plate 17 is horizontally installed at the lower end of the positioning plate 16 by a positioning bolt. It is connected to the sliding seat 13 by a double-ended screw 15. With the T-shaped movable groove 8, movable plate 9, positioning plate 16 and triangular folding plate 17, it is easy to achieve precise folding of the plastic woven bag. The pressing mechanism includes fixed blocks 14 movably installed on both sides of the support plate 1. A telescopic spring is installed between the upper end of the fixed block 14 and the support plate 1, and a pressure roller 10 is rotatably installed between the fixed blocks 14. Through the fixed blocks 14, telescopic spring and pressure roller 10 on both sides of the support plate 1, it is easy to press the folded woven bag.

[0023] Working principle: When using this utility model, the woven bag is first passed from one end of the guide plate 2 on the upper end of the support plate 1 to the other end. At this time, the electric telescopic rod 5 is activated to move the lifting plate 7 downward, thereby initially guiding and limiting the woven bag through the fixed roller 12. Then, the servo motor 6 is activated to drive the bidirectional screw 15 to rotate. Since the threads at both ends of the bidirectional screw 15 rotate in opposite directions, the sliding seats 13 on both sides move inward or outward along the bidirectional screw 15, while simultaneously driving the moving rings on both sides of the fixed roller 12 to slide, thereby allowing the woven bag to move inward. The side edge is raised upwards. Then, according to the width of the woven bag and the folding size requirements, the position and angle of the positioning plate 16 and the triangular folding plate 17 are adjusted by adjusting the bolts to set the width and shape of the fold. Then, by pushing the moving plate 9 to slide in the T-shaped moving groove 8, the triangular folding plate 17 folds the raised edge of the woven bag downwards. After the woven bag is folded, the elastic force of the telescopic spring pushes the pressure roller 10 to press the folded woven bag downwards, pressing the folded edge to ensure that the fold is flat and firm, and to prevent the fold from springing back.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
