[0027] In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0028] Please refer to Figures 1-4 The embodiment aims to provide a paper feeding device of automatic paper folding machine, which comprises a paper feeding mechanism 1, a cutting mechanism 2 and a workbench 4, a driving motor 6 is located below the workbench 4 and is connected with a rotating shaft 12 through a conveying belt 7. When the driving motor 6 is started, it drives the rotating shaft 12 to rotate through the conveying belt 7, and then drives the action of the whole cutting mechanism 2. The rotating shaft 12 penetrates through two side plates 20 and is provided with rotating darts 9 on both sides, the surfaces of the rotating darts 9 are provided with central grooves 13, the rotating shaft 12 is inserted into the central grooves 13, so that the rotating darts 9 can stably rotate with the rotating shaft 12. The surfaces of the rotating darts 9 are also provided with grooves for embedding fixing bolts 11.

[0029] The fixing bolts 11 are movably arranged in the grooves on the surfaces of the rotating darts 9 and are connected with the bottom ends of L-shaped rods 19. The L-shaped rods 19 are located in the U-shaped grooves 10 of the fixing frames 8, the U-shaped grooves 10 not only provide accurate guide paths for the L-shaped rods 19, but also play a limiting role, so that the L-shaped rods 19 can stably move up and down in the predetermined track. With the rotation of the rotating darts 9, the fixing bolts 11 push or pull the L-shaped rods 19 to move in the vertical direction in the U-shaped grooves 10, so that the effective conversion from rotary motion to linear motion is realized.

[0030] The upper end of the L-shaped rod 19 is fixedly connected with a connecting plate 17, and the bottom end of the connecting plate 17 is provided with a cutting knife 18. Therefore, with the vertical movement of the L-shaped rod 19, the connecting plate 17 and the cutting knife 18 also rise or fall. When the rotating dart 9 rotates to a certain angle, the L-shaped rod 19 is pushed upward, so that the cutting knife 18 contacts and cuts the continuous paper 3; when the rotating dart 9 continues to rotate, the L-shaped rod 19 falls again, so that the cutting knife 18 is separated from the paper, and a complete cutting cycle is completed. Such a design ensures the consistency and accuracy of each cutting action, and improves the quality of the finished product.

[0031] The two side plates 20 are provided with a placement table 5 for supporting and guiding the continuous paper 3. The continuous paper 3 on the placement table 5 is sent to the subsequent process after being cut. In order to further enhance the stability and flexibility of the system, the middle part of the opposite side of the side plate 20 is provided with a fixed sliding groove block 15, and the connecting plate 17 is provided with a sliding block 16 at the corresponding position. The sliding block 16 can vertically slide in the fixed sliding groove block 15, so that the connecting plate 17 always maintains a vertical state during the upward and downward movement, and the cutting error caused by inclination is avoided.

[0032] In addition, the two side plates 20 are also vertically movable with a movable plate 14, which is provided with symmetrical through grooves. The rotating dart 9 is crossly arranged with the movable plate 14 through the upper end groove, which enhances the adaptability of the system to paper of different thickness and material. The design of the movable plate 14 enables the machine to flexibly adjust the cutting depth and position according to actual needs, so as to adapt to the needs of paper of various specifications.

[0033] In summary, through the cooperative work of the above components, the effective conversion from rotary motion to precise straight cutting is realized, the stability and precision of the cutting process are ensured, and the working efficiency and product quality of the entire automatic paper folding machine are improved. This design not only simplifies the mechanical structure and reduces the maintenance cost, but also significantly improves the ability of the equipment to process diversified paper, and meets the needs of modern industrial production for high efficiency and high precision processing.

[0034] Working principle: In specific work, through the drive motor 6 start driving the conveyor belt 7 and the rotating shaft 12 rotation, and then make the installation on the rotating shaft 12 on the rotating dart 9 synchronous rotation. With the rotation of the rotating dart 9, the fixed bolt 11 in the groove on its surface pushes the L-shaped rod 19 along the U-shaped groove 10 of the fixed frame 8 to move vertically. The connecting plate 17 connected to the upper end of the L-shaped rod 19 drives the cutting knife 18 to complete the cutting action. When the rotating dart 9 rotates to a certain angle, the L-shaped rod 19 is pushed up, and the cutting knife 18 contacts and cuts the continuous paper 3; continue to rotate, the L-shaped rod 19 drops, and the cutting knife 18 is separated from the paper, completing a cutting cycle. The setting table 5 supports the continuous paper 3, ensuring its stable conveying; the movable plate 14 and the fixed sliding block 15 between the side plate 20 cooperate with the sliding block 16, ensuring the vertical stability and adaptability in the cutting process. Through the coordinated work of these components, the whole system realizes the effective conversion from rotary motion to precise linear cutting, ensuring efficient and stable cutting effect.
