[0061] In another embodiment of the present invention, Figure 8 As shown, the front-suction double-sheet-free pasting machine also includes a material picking mechanism 70 for picking out paper; the material picking mechanism 70 includes a material picking connecting shaft 71 and a plurality of discharge blades 72, and the two ends of the material picking connecting shaft 71 in the length direction are respectively tightly connected to the two ends of the inner wall of the mounting cavity 12, and the material picking connecting shaft 71 is arranged on the side of the first roller 53, and the discharge blades 72 are evenly spaced on the material picking connecting shaft 71 and are connected to the surface of the first roller 53 for picking out paper. Specifically, a material removal connecting shaft 71 is installed on the side of the first roller 53, and six unloading blades 72 are installed on the material removal connecting shaft 71. The angles of the six unloading blades 72 can be adjusted by rotating the material removal connecting shaft 71. The six unloading blades 72 are all connected to the surface of the first roller 53. After the paper is output from the other end of the second roller 54 and the third roller 55, the six unloading blades 72 can scrape the paper off the surface of the second roller 54 to prevent the paper from sticking to the surface of the second roller 54 and preventing paper jams.

[0062] In another embodiment of the present invention, Figure 1As shown, the front suction double-sheet pasting machine further includes a folding plate 80; the folding plate 80 is retractably arranged beside the support seat 21 for supporting paper. Specifically, a folding plate 80 is further arranged beside the support seat 21, and the folding plate 80 is retractably installed at the bottom of the support seat 21. When the folding plate 80 is needed, the folding plate 80 can be pulled out from the bottom of the support seat 21 to increase the paper placement area. When the folding plate 80 is not needed, the folding plate 80 can be retracted to the bottom of the support seat 21 to save space and facilitate supporting paper of different shapes.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
