[0042] In this embodiment, an upper pressing roller 2 and a lower pressing roller 3 are arranged on the frame 1, and the upper pressing roller 2 and the lower pressing roller 3 form a forming gap 4. The upper pressing roller 2 and the lower pressing roller 3 are both rotatably arranged on the frame 1. A core wire 5 is also arranged on the frame 1, and the core wire 5 is used to overlap paper. After the paper is overlapped on the core wire 5, the upper pressing roller 2 and the lower pressing roller 3 rotate to drive the paper to be wound on the core wire 5, thereby forming a core rod, realizing the automated production of the core rod, improving the efficiency of the core rod production, and also reducing the generation of defective core rods.

[0043] Furthermore, it also includes: a blowing pipe 6 arranged on the frame 1, and the blowing pipes 6 are respectively located on both sides of the core wire 5. The blowing pipe 6 has an air outlet 7, and the air outlet 7 on one side of the core wire 5 faces the bottom surface of the paper, and the air outlet 7 on the other side faces the top surface of the paper.

The blowing pipes 6 on both sides have air outlets 7. The air outlets 7 are used for blowing air, and the blowing directions of the blowing outlets located on both sides of the core wire 5 are opposite. When the paper is overlapped on the core wire 5, the blowing outlets on the blowing pipes 6 start to discharge air, so that the paper on the core rod has a tendency to be wound on the core wire 5. The setting of the blowing pipes 6 enables the process of the upper pressing roller 2 and the lower pressing roller 3 driving the paper to form a core rod to have a higher forming rate, further reduces the generation of defective core rods, and improves the production efficiency and quality.

[0045] Furthermore, it also includes: a first telescopic member 8 arranged on the frame 1; a push plate 9 arranged on the telescopic end of the first telescopic member 8, the push plate 9 has a penetration hole 10, the push plate 9 is penetrated on the core wire 5 through the penetration hole 10, and after the first telescopic member 8 is extended and retracted, the push plate 9 is pushed to slide along the core wire 5.

[0046] In this embodiment, a first telescopic member 8 and a push plate 9 are provided on the frame 1.

The second telescopic member 11 and the third telescopic member 12 drive the upper pressure roller 2 and the lower pressure roller 3 to adjust the size of the forming gap 4, thereby further facilitating the sliding of the push plate 9 so that the process of detaching from the core rod will not be interfered with. When the blowing tube 6 starts to blow, the upper pressure roller 2 and the lower pressure roller 3 are both away from the core wire 5, so that the blowing tube 6 can blow the paper with a larger movement amplitude, and then the upper pressure roller 2 and the lower pressure roller 3 move to directly fold and press the paper after being blown by the blowing tube 6, thereby further increasing the forming rate of the core rod forming.
