[0017] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 5 As shown, the sheet feeding machine of this utility model includes a mounting base 20, on which a driving device is fixed; a sheet loading rack 1, which is fixed on the mounting base 20, and one end of the sheet loading rack 1 is provided with a sheet feeding port; a sheet conveyor belt 12, which is located below the sheet feeding port; and a sheet transfer device, which is rotatably mounted on the mounting base 20 and located between the sheet feeding port and the sheet conveyor belt 12. The sheet transfer device is driven by the driving device to transfer the sheet located at the sheet feeding port to the sheet conveyor belt 12. This setup allows for automated feeding of sheet 2 using a sheet feeding machine, replacing traditional manual feeding. This improves work efficiency and saves labor. Specifically, in the initial state, multiple sheets 2 are stacked side-by-side on the sheet loading rack 1. During feeding, a drive device drives the sheet transfer device, which cyclically transfers the sheet 2 located at the sheet feeding port to the sheet conveyor belt 12. The sheet 2 is then transported to the next process via the sheet conveyor belt 12.

[0019] The sheet 2 is a paper sheet material, which can be any sheet material among folding paper boxes, cardboard, and paper.

[0020] Furthermore, the sheet transfer device includes a rotating shaft 4, a swing arm 5, an air pipe 6, and a vacuum suction cup 7. The rotating shaft 4 is rotatably mounted on the mounting base 20. The first end of the swing arm 5 is fixedly connected to the rotating shaft 4. The air pipe 6 is rotatably mounted on the second end of the swing arm 5. At least one vacuum suction cup 7 is provided on the air pipe 6, and the air pipe 6 is provided with an air pipe connection port 21 for connecting an external vacuum generator. The rotating shaft 4 is driven to rotate in both directions by a driving device, so that the air pipe 6 drives the vacuum suction cup 7 to circulate between the sheet feeding port and the sheet conveyor belt 12. A steering assembly is provided between the air pipe 6 and the mounting base 20. The steering assembly is used to adjust the rotation angle of the air pipe 6 relative to the swing arm 5, thereby adjusting the angle of the vacuum suction cup 7. With this configuration, in the initial state (e.g. Figure 4 and Figure 5 As shown), the air pipe 6 drives the vacuum suction cup 7 to be positioned at the sheet feeding port, and works with the vacuum generator to create a vacuum to hold the sheet 2 in place; during feeding, the drive device drives the rotating shaft 4 to rotate counterclockwise, and the rotating shaft 4 drives the swing arm 5 to rotate counterclockwise around the rotating shaft 4 as the axis. During this process, the swing arm 5 drives the air pipe 6 to move relative to the sheet conveyor belt 12 until the feeding state is reached (as shown). Figure 1 and Figure 2 (As shown), and then with the help of a vacuum generator to introduce air, a vacuum is created. The suction cup 7 places the sheet 2 on the sheet conveyor belt 12, which transports the sheet 2 to the next process. The drive device drives the rotating shaft 4 to rotate clockwise. When the rotating shaft 4 rotates, it drives the swing arm 5 to rotate clockwise around the rotating shaft 4. During this process, the swing arm 5 drives the air pipe 6 to move relative to the sheet feeding port until it returns to its initial state (as shown). Figure 4 and Figure 5 (As shown), repeat this process until all sheets 2 have been cut. During the movement of the air pipe 6 driven by the swing arm 5, the air pipe 6 is adjusted by the steering component to rotate the vacuum suction cup 7 relative to the swing arm 5. Specifically, in the initial state, the vacuum suction cup 7 faces the sheet feeding port. During feeding, the vacuum suction cup 7 changes from facing the sheet feeding port to facing the sheet conveyor belt 12.

[0021] Furthermore, the drive device includes a servo motor 3, a driving wheel 13, a driven wheel 14, and a synchronous belt 15. The servo motor 3 is mounted on the mounting base 20, the driving wheel 13 is mounted on the output end of the servo motor 3, the driven wheel 14 is fixedly connected to the rotating shaft 4, and the synchronous belt 15 is wound around the driving wheel 13 and the driven wheel 14. With this configuration, when the servo motor 3 is working, it drives the driving wheel 13 to rotate. When the driving wheel 13 rotates, it drives the synchronous belt 15 and the driven wheel 14 to rotate. When the driven wheel 14 rotates, it drives the rotating shaft 4 to rotate.

[0022] Furthermore, the steering assembly includes a steering rod 8, a mounting bracket 9, a steering component 10, and a linear bearing 11. The mounting bracket 9 is fixed to the mounting base 20, the steering component 10 is rotatably mounted on the mounting bracket 9, and the linear bearing 11 is fixed to the steering component 10. The first end of the steering rod 8 is fixed to the air pipe 6, and the second end of the steering rod 8 passes through the linear bearing 11, with the steering rod 8 and the linear bearing 11 slidably connected. With this configuration, in the initial state (e.g....), Figure 4 and Figure 5As shown), at this time, the suction port of the vacuum suction cup 7 faces the sheet material discharge port; when the drive device drives the swing arm 5 to move the air pipe 6 relative to the sheet conveyor belt 12, the position between the steering rod 8 and the steering component 10 changes. Specifically, when the air pipe 6 approaches the sheet conveyor belt 12, the steering rod 8 extends relative to the linear bearing 11. During the extension process, the swing arm 5 drives the air pipe 6 to move in an arc around the rotating shaft 4. The end of the steering rod 8 connected to the air pipe 6 rotates around the end connected to the steering component 10, realizing the rotation of the air pipe 6. At the same time, the steering component 10 will rotate a certain angle relative to the fixed frame 9. When the air pipe 6 rotates to be below the steering component 10, the suction port of the vacuum suction cup 7 faces the sheet conveyor belt 12. As the air pipe 6 continues to approach the sheet conveyor belt 12, the steering rod 8 extends relative to the linear bearing 11 until the material discharge form (as shown) is reached. Figure 1 and Figure 2 As shown), complete the cutting of sheet 2.

[0023] Furthermore, the mounting base 20 is provided with two first bearing seats 22 spaced apart, and the rotating shaft 4 is rotatably mounted between the two first bearing seats 22. The first bearing seats 22 are provided with first ball bearings that cooperate with the rotating shaft 4. With this arrangement, the rotating shaft 4 is limited by the two first bearing seats 22, so that when the swing arm 5 drives the air pipe 6 to rotate, it rotates around the rotating shaft 4 as the axis.

[0024] Furthermore, the fixed frame 9 is provided with a second bearing seat 23, and the steering component 10 is rotatably mounted on the second bearing seat 23. The second bearing seat 23 is provided with a second ball bearing that cooperates with the steering component 10. In this configuration, the second bearing seat 23 limits the steering component 10, so that when the steering component 10 rotates, it rotates around the second ball bearing as the axis.

[0025] The steering component 10 has a through hole, and the linear bearing 11 is inserted into the through hole.

[0026] Furthermore, the sheet loading rack 1 includes a base plate 16 and two side plates 17. The two side plates 17 are symmetrically installed on both sides of the base plate 16 and form a U-shaped sheet receiving groove. The base plate 16 is installed at an incline on the mounting base 20, with the lower end of the base plate 16 corresponding to the feed end of the sheet conveyor belt 12. The sheet discharge port is located at the lower end of the base plate 16. With this configuration, multiple sheets 2 can be easily stacked into the U-shaped sheet receiving groove, and the incline of the base plate 16 facilitates the sequential movement of multiple sheets 2 in the U-shaped sheet receiving groove to the sheet discharge port position under gravity along the inclined base plate 16.

[0027] Furthermore, a gantry frame 18 is provided on the sheet feeding port, and a sheet limiting member 19 is provided on the gantry frame 18. With this configuration, in the initial state, the sheet limiting member 19 provides a certain limit to the sheet 2 located at the sheet feeding port, preventing the sheet 2 from detaching from the sheet feeding port on its own. When the vacuum suction cup 7 abuts against the sheet 2 at the sheet feeding port, the sheet 2 is adsorbed and fixed under the action of the vacuum generator. When the air pipe 6 moves the vacuum suction cup 7 away from the sheet feeding port, the surface of the sheet 2 deforms under the action of force, and can detach from the sheet limiting member 19.

[0028] Specifically, since sheet 2 is a paper-like material, the vacuum suction cup 7 is adsorbed at the center of the surface of sheet 2. Under the action of force, the surface of sheet 2 arches up and undergoes arc-shaped deformation. At this time, sheet 2 can slide out relative to sheet limiting member 19.

[0029] The sheet limiting member 19 can limit only the left and right sides or the top and bottom sides of the outer periphery of the sheet 2, and the limiting range is small, such as 1 cm or less, so that the sheet 2 can be removed from the gantry frame 18.

[0030] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present utility model.
