Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0025] This embodiment provides a plastic woven bag folding machine. Figures 1 to 5 As shown, it includes a conveyor 1, and two limit plates 2 symmetrically distributed front and back are installed at the upper end of the conveyor 1. The limit plate 2 is used to limit the position of the plastic woven bag. A vertical plate 3 is installed at the rear end of the conveyor 1, and the middle part of the front end of the vertical plate 3 is connected to the first baffle 4 through a support frame. A folding part 5 is installed at the upper and middle part of the front end of the vertical plate 3. The folding part 5 includes a third cylinder 53, and the third cylinder 53 is installed on the vertical plate 3. The output end of the third cylinder 53 is fixedly connected to the second cylinder 51, and the output end of the second cylinder 51 is fixedly connected to the folding plate 52. The folding plate 52 is located above the first baffle 4, and a second baffle 7 is provided on the front side of the first baffle 4; when in use, the woven bag filled with materials is placed on the conveyor 1, and the conveyor 1 drives the woven bag to move to the left, and the limit plate 2 limits the moving direction of the woven bag. Position, so that the opening of the woven bag moves to between the first baffle 4 and the second baffle 7. When the opening moves to the vicinity of the folding part 5, the conveyor 1 is controlled to stop running, and the output end of the second cylinder 51 is controlled to drive the folding plate 52 to move forward above the second baffle 7, so that the top of the woven bag is an inverted L-shaped structure. Then the output end of the third cylinder 53 is controlled to drive the second cylinder 51 to move downward, and drive the bending part of the woven bag to move downward, so as to complete the folding of the woven bag. However, due to the uncertain shape of the opening of the woven bag, the folding part of the woven bag is not easy to move between the first baffle 4 and the second baffle 7 when used. If the woven bag is not correctly guided into the folding area at the folding part, the folding part will be unstable or unevenly folded, and manual adjustment or intervention will be required, which reduces the degree of automation and production efficiency of the folding process.

[0026] In order to improve the above-mentioned disadvantages, the folding part of the woven bag is driven to move to the first baffle 4 and the second baffle 7 through the cooperation of the splint 10, the support block 9 and the driving component 12. To this end, a movable support block 9 is provided at the lower right side of the first baffle 4, and two rotatable splints 10 are provided at the front end of the support block 9. The two splints 10 fix the opening of the woven bag at the front end of the support block 9, and the support block 9 moves synchronously with the conveyor 1 to move the opening of the woven belt between the first baffle 4 and the second baffle 7; the front end of the support block 9 is equipped with two support seats 13 symmetrically distributed on the left and right, and the lower ends of the two support seats 13 are movably connected to the connecting rod 14, and the two splints 10 are movably sleeved on the two The lower ends of the two connecting rods 14 are respectively connected to the two rotating cylinders installed under the support block 9; the front end of the vertical plate 3 is equipped with a driving component 12, which is used to drive the support block 9 to move. The driving component 12 includes a bearing seat 122, which is installed on the vertical plate 3. The right end of the bearing seat 122 is movably connected to a screw rod 121, and a slider 123 is provided on the outer surface of the screw rod 121. The right end of the screw rod 121 is connected to the second motor installed on the vertical plate 3. The rear end of the slider 123 is slidably connected to the vertical plate 3. The front end of the slider 123 is equipped with an electric cylinder 124, and the rear end of the support block 9 is fixedly connected to the output end of the electric cylinder 124;

[0027] When the woven bag moves to the front side of the support block 9, the conveyor 1 is controlled to stop running, and the output end of the electric cylinder 124 is controlled to extend, driving the support block 9 to move forward so that the support block 9 is against the back side of the woven bag. Then, the two rotary cylinders are controlled to respectively drive the two clamping plates 10 to rotate toward the woven bag through the connecting rod 14, so that the clamping plates 10 fix the top of the woven bag on the support block 9. The rotary cylinder is controlled to rotate the screw rod 121, which drives the slider 123 to move left, and the slider 123 drives the support block 9 to move left. At the same time, the conveyor 1 is controlled to start, so that the belt on the conveyor 1 moves synchronously with the support block 9. Then, the top of the woven bag is guided between the first baffle 4 and the second baffle 7, facilitating the subsequent folding, improving the stability of the folding or folding flatness, and eliminating the need for manual adjustment or intervention, thereby improving the automation and production efficiency of the folding process. After the guidance is completed, the rotary cylinder is controlled to drive the clamping plates 10 to return to their original position, and the output end of the electric cylinder 124 is controlled to return to its original position. The driving component 12 is controlled to drive the support block 9 to return to its original position.

[0028] In order to reduce the supporting pressure at the output end of the electric cylinder 124, a through groove 31 is opened at the rear end of the vertical plate 3, and a guide rod 125 is arranged in the through groove 31. The guide rod 125 movably passes through the slider 123 and is fixedly connected to the rear end of the support block 9. Two guide rods 125 are provided, and the support block 9 can be supported by the guide rods 125.

[0029] In addition, in order to ensure that the splint 10 can accurately fix the opening of the woven bag, a support member 11 is installed above the support block 9. The support member 11 is composed of two symmetrically arranged support rods 114. The opening of the woven bag is opened by the two support rods 114 moving in opposite directions. Specifically, an L-shaped frame 111 is installed on the upper end of the support block 9, and a first cylinder 112 is installed on the upper end of the L-shaped frame 111. The output end of the first cylinder 112 is movable through the upper wall of the L-shaped frame 111 and is fixedly connected to a two-way cylinder 113. The two conveying ends of the two-way cylinder 113 are fixedly connected to the support rods 114. Before the woven bag is fixed, the control The output end of the first cylinder 112 drives the two-way cylinder 113 to move downward, so that the support rod 114 moves into the woven bag. By controlling the two output ends of the two-way cylinder 113 to extend respectively, driving the two support rods 114 away from each other, the top of the woven bag can be opened. After the top of the woven bag is opened, the bag opening can be displayed more flatly, which helps the splint 10 to fix the bag opening more accurately and avoid the situation where the woven bag is not firmly fixed or offset due to wrinkles or looseness. After the splint 10 is fixed, the output end of the two-way cylinder 113 is controlled to reset, and the output end of the first cylinder 112 is controlled to drive the support rod 114 away from the woven bag.

[0030] In addition, a pressing plate 6 is provided on the upper left side of the first baffle 4 and the second baffle 7. The pressing plate 6 is fixed on the vertical plate 3. The pressing plate 6 is an L-shaped structure. The pressing plate 6 extends to the front side of the second baffle 7. There is a gap between the vertical area of ​​the pressing plate 6 and the second baffle 7. There is a gap between the horizontal position of the pressing plate 6 and the upper ends of the first baffle 4 and the second baffle 7. When the folding of the woven bag is completed, the pressing plate 6 can prevent the folding of the woven bag from being reset, ensuring that the folding can be sealed with a sewing machine later. The front end of the pressing plate 6 is provided with a screw hole and a groove for conveniently fixing the sewing machine. In order to fix the second baffle 7, this embodiment also installs an L-shaped plate 8 on the front end of the second baffle 7. The L-shaped plate 8 is installed on the vertical plate 3.
