[0035] There are two clamp arm assemblies 3 , and the two clamp arm assemblies 3 are arranged opposite to each other.

[0036] Specifically, in this embodiment, two mutually parallel guide rails 2 are installed at the bottom of the frame 1, and two sets of clamp arm assemblies 3 are respectively installed at both ends of the guide rails 2 in the length direction. Each set of clamp arm assemblies 3 includes a bottom plate 31, a clamp 32, a first driving member 33, a second driving member 34 and a bearing seat 35. The first driving member 33 adopts an oil cylinder, and the second driving member 34 adopts an oil cylinder. The bearing seat 35 is fixedly connected to the bottom plate 31, and one end of the clamp 32 is rotatably connected to the bearing seat 35. The other end of the clamp 32 is used to clamp the base paper 100. First, the two second driving members 34 respectively drive the clamps 32 so that the central axes of the free ends of the two clamps 32 coincide with the central axis of the base paper 100, and then the two first The driving member 33 drives the two bottom plates 31 respectively to synchronously drive the clamps 32 to move toward the direction of the base paper 100, that is, the two clamps 32 respectively contact the two ends of the base paper 100 and clamp the base paper 100, and then enters the correction stage. The two second driving members 34 respectively drive the swing angles of the two clamps 32 to achieve the purpose of correcting the center overlap of the two clamps 32 and the base paper 100. Then, the two first driving members 33 respectively drive the two bottom plates 31 to slide in the direction of approaching each other, so that the two clamps 32 clamp the base paper 100. Finally, the two second driving members 34 respectively drive the two clamps 32 to swing, so that the base paper 100 rotates to a preset position to prepare for the next process.

[0037] By setting two clamping arm assemblies 3, each clamping arm assembly 3 includes a base plate 31, a clamp 32, a first driving member 33, and a second driving member 34, the purpose of independently controlling the swing and horizontal movement of each clamp 32 is achieved, the purpose of accurately correcting the base paper 100 is achieved, the production efficiency is improved, and the energy consumption is reduced.
