1. Type: Horizontal multi-stage differential conveying to produce separation counting and paper stacking effects
2. First conveying section: suction conveying for quick separation and cutting of paper, quick waste discharge device.
3. Second conveying section: The suction tail conveying can be controlled by single or continuous action, and the paper can be adjusted to be sent out in a tile like manner
4. Paper delivery section: Refined paper separator, which can be adjusted in conjunction with the paper width.
5. The pressure feeding wheel can increase the stability of the paper and avoid paper offset
