Under the tension of the tension springs 9 on both sides, the second conveyor belt 8 and the first conveyor belt 5 are abutted.

[0037] A woven bag cutting device provided by an embodiment of the present disclosure includes a support seat 1, a mounting plate 2, an active roller 3, a driven roller 4, a first conveyor belt 5, a roller shaft 6, a roller 7, a second conveyor belt 8 and a tension spring 9. The mounting plate 2 is connected to the support seat 1 and is located on both sides of the support seat 1 along the height direction of the support seat 1. The planes of the upper and lower mounting plates 2 overlap each other and are both perpendicular to the ground. The active roller 3 is rotatably mounted on the lower mounting plate 2 to drive the first conveyor belt 5 to rotate. The driven roller 4 is rotatably mounted on the lower mounting plate 2 to support the first conveyor belt 5. Along the width direction of the support seat 1, the driven roller 4 and the active roller 3 are located on both sides of the support seat 1, thereby supporting the first conveyor belt 5 sleeved between the active roller 3 and the driven roller 4, so that the first conveyor belt 5 can move along a specific trajectory.

When cutting the woven bag, lift the first conveyor belt 5 upward, and the tension spring 9 can be stretched. Thus, a gap is formed between the first conveyor belt 5 and the second conveyor belt 8, and the woven bag can be placed on the second conveyor belt 8. Then release the first conveyor belt 5, and under the tension of the tension spring 9, the first conveyor belt 5 can move downward, thereby pressing the woven bag placed on the second conveyor belt 8. Then control the active roller 3 to rotate, and under the support of the driven roller 4, the first conveyor belt 5 can rotate. Under the action of friction and the support of the rollers 7 on both sides, the second conveyor belt 8 can rotate synchronously. Thus, the woven bags located on the first conveyor belt 5 and the second conveyor belt 8 are continuously conveyed, realizing the automatic feeding function and improving the cutting efficiency of the woven bag.

[0049] During use, the cylinder 13 is controlled to work, which can drive the moving plate 14 to move. Then the cutter 15 is driven to move, and finally the woven bag is cut. At the same time, driven by the springs 16 on both sides, the pressing plates 17 on both sides will move synchronously until they collide with the woven bag and press and fix the woven bag.
