[0026] Furthermore, a pressing mechanism 9 is provided below each of the two mounting plates 11. The pressing mechanism 9 includes a housing 901, a connecting plate 902, and a roller box 903. The housing 901 is fixedly connected to the mounting plate 11. The connecting plate 902 is located below the housing 901, and the upper end of the connecting plate 902 extends into the interior of the housing 901. The roller box 903 is fixedly installed below the connecting plate 902. A pressure roller 10 is rotatably installed inside the roller box 903. A motor is fixedly installed at the front end of the roller box 903. The output end of the motor is fixedly connected to the pressure roller 10. The conveying of the woven bag is realized through the rolling pressing of the pressure roller 10 and the drive of the motor.

[0027] Furthermore, a compression spring 19 is provided inside the housing 901. The upper end of the compression spring 19 is fixedly connected to the housing 901, and the lower end of the compression spring 19 is fixedly connected to the connecting plate 902.

The combination of the conveyor belt 12 and the belt rollers 13 realizes the automatic conveying of woven bags, simplifies the operation process, improves production efficiency, and is also conducive to continuous operation.

[0031] Working principle: During use, the conveyor belt 12 is driven by the drive motor to rotate the belt roller 13, realizing the automatic conveying of woven bags to the cutting table 14. Before cutting, the electric cylinder 2 5 drives the mounting plate 11 and the fixed pressure plate 16 and rubber pad below it to descend quickly, firmly pressing the woven bag to prevent deviation. At the same time, the compression spring 19 is compressed, causing the pressure roller 10 to elastically press down on the woven bag. Subsequently, the electric cylinder 1 4 drives the knife holder 7 and the cutting knife 8 to move up and down to perform the cutting action. During this period, the guide block 18 and the guide slide cooperate to prevent cutting deviation and ensure cutting accuracy. After cutting, the fixed pressure plate 16 is driven to move up a certain distance and make the pressure roller 10 still in contact with the woven bag. By driving the pressure rollers 10 in the two roller boxes 903 respectively, the cut woven bags are output and subsequent woven bags are conveyed to the cutting table 14.
