The folding area is provided with a vertical folding triangular bucket, and the feeding part of the folding area is provided with a 45-degree turning frame. After the material is discharged by the swing arm, it bypasses the roller and goes around to the upper part of the 45-degree turning frame, and then passes through the roller and is folded in half through the folding triangular bucket. When it is put into production, the material is inevitably offset when being transported through the turning frame, rollers and folding triangular bucket. Due to the lack of a correction mechanism, errors occur in the folding of the material, which affects the normal operation of subsequent processes and thus affects the quality of the finished product.

There are photoelectric components c5 for detecting whether the material is deflected, and two groups of anti-deflection components c6 distributed up and down for intermittently pressing the material. The material input side of the folding frame c1 is provided with a folding correction component c7 for adjusting the material. The folding correction component c7 comprises a correction motor c71 fixed on the folding frame c1, and a correction screw rod c72 arranged at the output end of the correction motor c71.

The upper and lower end surfaces of the suspended end of the folding anti-deflection mounting frame c61 are respectively connected to the first pressing wheel mounting arm c62 and the second pressing wheel mounting arm c63. One end of the first pressing wheel mounting arm c62 is connected to the folding anti-deflection mounting frame c61, and the other end extends toward the folding edge c42 of the folding triangle plate c4 and is provided with a pressing wheel cylinder c64. The output end of the pressing wheel cylinder c64 is provided with a first pressing wheel c65. One end of the second pressing wheel mounting arm c63 is connected to the folding anti-deflection mounting frame c61. The first pressing wheel c65 is rotatably arranged on the first U-shaped pressing wheel frame c67, and the second pressing wheel mounting arm c63 has a second U-shaped pressing wheel frame c68 at the end thereof.
