Non-indentation type pressing and clinging device of single facer in corrugated board production and pressing and clinging method

The invention discloses a non-indentation type pressing and clinging device of a single facer in corrugated board production and a pressing and clinging method, a plurality of grooves are formed in the upper end of a shell, square grooves are formed below the grooves, pressing and clinging devices are arranged in the grooves, and the pressing and clinging devices are arranged in the square grooves. The pressing and attaching device comprises a device body, a flexible paper pressing roller, a pressurizing air cylinder assembly, a pressurizing spring assembly and a touch pressing plate type arc-shaped paper pressing plate assembly. The device has the beneficial effects that a corrugated paper core pressed by an upper corrugated roller and a lower corrugated roller and corrugated surface paper entering through a square groove can be drafted through the flexible paper pressing roller arranged in the device main body, and the corrugated paper core cannot be damaged due to indentation in the drafting process; the c
