[0023] Specific implementation examples Figure 1 As shown, this utility model relates to a horizontal fine-tuning mechanism for a paper feeding table, including a fixed frame 1. The fixed frame 1 is provided with a lifting platform 2 and a paper feeding table 3. The paper feeding table 3 is located at the upper end of the lifting platform 2. Crucially, the lifting platform 2 and the paper feeding table 3 are separate structures. The fixed frame 1 is provided with a horizontal movement drive unit. The drive end of the horizontal movement drive unit is connected to a first vertical guide rail 4. The paper feeding table 3 is guided and connected to the first vertical guide rail 4. The first vertical guide rail 4 has a degree of freedom to move horizontally relative to the fixed frame 1 by means of the drive of the horizontal movement drive unit. The paper feeding table 3 has a degree of freedom to move horizontally relative to the lifting platform 2 by means of the push of the first vertical guide rail 4. This invention designs the lifting platform 2 and the paper feeding table 3 as separate structures. When the lifting platform 2 rises, the paper feeding table 3 is lifted by the lifting platform 2; when the lifting platform 2 falls, the paper feeding table 3 falls with the lifting platform 2 under the action of gravity, so that the paper feeding table 3 is guided and connected to the first vertical guide rail 4. The first vertical guide rail 4 is driven to move laterally relative to the lifting platform 2 by the transverse drive unit. During the transverse movement of the first vertical guide rail 4, the paper feeding table 3 is also moved laterally, which corrects the paper on the paper feeding table 3 and ensures that the paper on the paper feeding table 3 can enter the correct conveying path and be accurately conveyed, thereby improving the fit between the paper and the feeder and improving the quality of the die-cut products.

The motor 5 drives the screw 6 to rotate, and the nut 7 moves linearly along the axial direction of the screw 6, thereby realizing the transverse movement of the first vertical guide rail 4 relative to the lifting platform 2. The driving method of this transverse drive unit has a simple structure and high transmission accuracy, and can accurately control the transverse movement distance of the paper feeding table 3, thereby improving the accuracy of the position of the paper at the top of the paper feeding table 3.

[0028] The paper feeding table 3 is guidingly connected with the first vertical guide rail 4 through the connecting assembly 10, as shown in Figure 2 , the connecting assembly 10 includes a guide sliding block 11 and a connecting block 12, the guide sliding block 11 is arranged in pairs with the first vertical guide rail 4, and the two ends of the connecting block 12 are fixedly connected with the paper feeding table 3 and the guide sliding block 11 respectively. During the horizontal movement, the first vertical guide rail 4 transmits power to the paper feeding table 3 through the guide sliding block 11 and the connecting block 12, so that the paper feeding table 3 moves horizontally synchronously with the first vertical guide rail 4.

[0029] The second vertical guide rail 13 is fixedly connected to the fixed frame 1, and the lifting table 2 is guidingly connected with the second vertical guide rail 13, so that the lifting table 2 moves more stably during the lifting movement, thereby ensuring that the paper feeding table 3 can maintain consistent horizontal fine adjustment accuracy at different height positions.
