[0024] Working principle: During operation, the valve bag enters the conveying mechanism 3 away from the side of the fixed-length cutting mechanism 5, and the motor 514 drives the driving pulley 515 to rotate. Under the transmission of the transmission belt 516, the driven pulley 512 drives the roller 501 to rotate.

[0025] During the valve bag conveying process, when it is conveyed to the position of the fixed-length cutting mechanism 5, the cutter 509 rotates one circle to cut the valve bag under the engagement of the second lower gear 510 and the second upper gear 511, thereby achieving fixed-length cutting; preferably, the diameter of the rotating roller 501 of the device is smaller than the diameter of the conveying roller 301, so that when the motor 514 is driven, the rotation direction of the rotating roller 501 is opposite to the direction of the conveying roller 301, thereby avoiding conflict with the conveyance of the valve port.
