The structure of the existing rolling forming head is shown in FIG. Figures 1-3 The straight-line tile mold 2 has the structure shown in FIG. Figure 4

[0003] As shown in FIG. Figure 5 The production process of the straight-line tile 5 is as follows: a plurality of straight-line tile molds 2 are arranged in sequence on the conveying line 3 and transported from left to right into the rolling forming head 1, the left side of the rolling forming head 1 is provided with a pusher to help the straight-line tile molds 2 on the conveying line 3 enter the rolling forming head 1. The feed hopper 4 located above the rolling forming head 1 feeds the semi-dry concrete raw materials, the feeding claws 12 in the rolling forming head 1 are responsible for uniformly dispersing the raw materials, the rotating circular forming roller 13 rolls the raw materials between the circular forming roller 13 and the straight-line tile mold 2, and finally forms the straight-line tile 5 shown in FIG. Figure 6 The straight-line tile 5 and the straight-line tile mold 2 are output from the right side of the rolling forming head 1.

[0004] However, when the straight-line tile 5 is under stress, the force is concentrated on a certain part of the straight-line tile 5, which cannot effectively disperse the pressure, resulting in low structural strength of the straight-line tile 5 and easy deformation or damage of the roof.
