Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In a specific embodiment of the present invention, Figure 1-2 As shown, a carton fast pre-folding tool comprises a frame 1, a first pre-folding guide rail 2 disposed on the frame 1 and used for pre-folding a front side wall 101 and a rear side wall 102 of a carton bottom, a second pre-folding guide rail 3 for pre-folding a left side wall 103 of a carton bottom, and a third pre-folding guide rail 4 for pre-folding a right side wall 104 of a carton bottom, wherein the first pre-folding guide rail 2 is located between the second pre-folding guide rail 3 and the third pre-folding guide rail 4;

[0021] A cavity 200 is provided between the first pre-folding guide rail 2 and the second pre-folding guide rail 3 and the third pre-folding guide rail 4, respectively, for inserting the left side wall 103 and the right side wall 104 of the bottom of the carton. The length of the first pre-folding guide rail 2 is less than the length of the second pre-folding guide rail 3 and the third pre-folding guide rail 4. The distance d1 between the second pre-folding guide rail 3 and the third pre-folding guide rail 4 changes from large to small. Specifically, during the carton pre-folding process, the distance d1 between the second pre-folding guide rail 3 and the third pre-folding guide rail 4 is initially greater than the carton width d2, facilitating the insertion of the left side wall 103 and the right side wall 104 of the bottom of the carton. The distance d1 at the end is less than the carton width d2. The design of the carton fast pre-folding tool of the present invention greatly reduces the time for manual pre-folding of cartons and improves the pre-folding efficiency of cartons.

[0022] Specifically, in this embodiment, the frame 1 is composed of a first H frame 11, a second H frame 12, and a first connecting rod 13 and a second connecting rod 14 connecting the first H frame 11 and the second H frame 12. The first H frame 11 is arranged parallel to the second H frame 12. One end of the first pre-folding guide rail 2 is fixed on the horizontal frame 111 of the first H frame 11. The second pre-folding guide rail 3 includes a first vertical segment 31 and a first straight segment 32.
