Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 A paper feeder for a cardboard processing machine includes a mounting frame 1 and a base 2 fixedly connected to the bottom wall of the mounting frame 1. The inner side of the base 2 is provided with a conveying structure for conveying cardboard.

[0021] like Figure 1 As shown, the conveying structure includes a ball bearing base plate 3 slidably connected to the inner bottom wall of the base 2, a motor 4 fixedly connected to the upper surface of the ball bearing base plate 3, a drive rod 5 fixedly connected to the output shaft of the motor 4, a drive gear 6 fixedly connected to the outside of the drive rod 5, racks 7 respectively meshing with the left and right sides of the drive gear 6, a connecting block 8 rotatably connected to the top of the drive rod 5, a placement platform 9 fixedly connected to the upper surface of the connecting block 8, a fixing plate 10 fixedly connected to the inner side of the placement platform 9, electric push rods 11 fixedly connected to the left and right sides of the fixing plate 10 respectively, a connecting plate 12 fixedly connected to the opposite ends of the left and right electric push rods 11 respectively, elastic telescopic rods 13 fixedly connected to the opposite side walls of the left and right connecting plates 12 respectively, and clamping plates 14 fixedly connected to the opposite ends of the left and right elastic telescopic rods 13 respectively.

[0022] It should be noted that the left and right racks 7 are fixedly connected to the inner top wall of the base 2, and the upper surface of the base 2 is provided with a connecting slide that is compatible with the connecting block 8.

[0023] The left and right sides of the bottom of the placement platform 9 are fixedly connected to the support block 15, and the left and right sides of the upper surface of the base 2 are provided with support slides that are compatible with the support block 15. The bottom of the support blocks 15 on both sides are fixedly connected to the support rods 16, and the bottom ends of the support rods 16 on both sides are fixedly connected to the upper surface of the ball bearing base plate 3.

[0024] The movable end of the left electric push rod 11 moves through the inner left side wall of the placement platform 9 and is fixedly connected to the left connecting plate 12, and the movable end of the right electric push rod 11 moves through the inner right side wall of the placement platform 9 and is fixedly connected to the right connecting plate 12.

[0025] Insert cylinders 17 are fixedly connected to the opposite side walls of the left and right connecting plates 12. Insert rods 18 are inserted into the inner sides of the left and right insert cylinders 17. Top plates 19 are fixedly connected between the top ends of the left and right insert rods 18.

[0026] There are two elastic telescopic rods 13 on each side, and the two elastic telescopic rods 13 on the same side are arranged sequentially along the vertical direction of the connecting plate 12 on the same side.

[0027] Rubber pads 1401 are fixedly connected to the opposite side walls of the left and right side plates 14, and the width and height of the rubber pads 1401 are equal to the width and height of the side plates 14, respectively.

[0028] In addition, the front of the base 2 is hinged with a maintenance door for repairing the internal components of the base 2.

[0029] The working principle of the above embodiments is as follows:

[0030] First, several cardboard pieces are stacked on the placement table 9. Then, the electric push rod 11 is activated. When the electric push rod 11 receives a control signal, its movable end retracts, driving the connecting plate 12 and the clamping plate 14 to move closer to the center of the cardboard, thereby clamping the cardboard. Furthermore, the elastic telescopic rod 13 provides the necessary buffer and self-adaptive capability for the clamping plate 14, which can automatically adjust the clamping force according to the size of the cardboard to avoid being too tight or too loose. At the same time, the rubber pad 1401 fixed on the clamping plate 14 further enhances the flexibility of the clamping and protects the cardboard from damage. In addition, by inserting the insertion rod 18 into the insertion cylinder 17, the top plate 19 is fixed to the top of the clamping plate 14, thereby forming a stable frame structure for the entire clamping component, enhancing the overall rigidity and stability of the clamping component.

[0031] Then, the motor 4 is started, and its output shaft drives the drive rod 5 and drive gear 6 to rotate. The drive gear 6 meshes with the racks 7 on the left and right sides, thereby converting the rotational motion into linear motion in the front and back direction. This drives the connecting block 8 and the placement table 9 to move linearly in the front and back direction along the connecting slide, thereby conveying the cardboard. Furthermore, since the ball bearing base plate 3 is slidably connected to the inner bottom wall of the base 2 through the bottom balls, the frictional resistance is reduced, and the smoothness and stability of the structural movement are improved. In addition, the design of the support block 15 and the support rod 16 further enhances the connection strength between the placement table 9 and the ball bearing base plate 3, so that the entire conveying structure remains stable during dynamic processes.

[0032] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
